The Study of Relational Chains: An Area of Social Network Analysis to Be Developed

The study of relational chains is one of the approaches used in social network analysis. It consists of documenting the activation of relationships between people in processes of accessing resources or other people. This approach makes it possible to study the phenomena of embeddedness (the dependence of various social activities on networks of relationships between individuals) and, more generally, the overall structure of networks in various socio-historical contexts.

Frequent Itemset-based Graph Numbering using Execution Traces for Cache Misses Reduction in Graph Analysis Tasks

Graph analysis applications are increasingly used on large-scale datasets, where memory access patterns have a significant impact on performance. In such applications, poor data locality leads to a high number of cache misses, which in turn degrades execution time. To address this issue, several graph numbering techniques have been proposed to reorganize data in memory, mainly based on structural properties of the graph. More recently, execution trace-based approaches such as NumBaClus have been introduced, leveraging clustering techniques to group nodes with similar access patterns. However, these methods do not explicitly capture the co-occurrence of nodes within the same execution contexts. In this paper, we propose NumBaFrIt, a new graph numbering approach based on frequent itemset mining of execution traces. By modeling execution traces as transactional data, our method identifies groups of nodes that are frequently accessed together and reorganizes them in memory to improve data locality. Experimental results show that NumBaFrIt improves base numbering and significantly enhances existing ordering strategies when used as a preprocessing step, leading to better cache efficiency and reduced execution time. This is for example the case on user machine with 3072 KB of cache memory, our proposal got the best cache misses reduction through the combination NumBaFrit-sup70_cn-order with 48.96% compared to 17.15% of cache misses reduction gotten with Cn-order_cl-h (an existing numbering of NumBaClus).

TESTS DE MONTE CARLO DE DETECTION DE RUPTURE(S) – APPLICATION A LA DETECTION D'UN CHANGEMENT BRUSQUE DU CLIMAT

The commonly employed test for detecting change-point are quite generally based on asymptotic approximations which may not provide good size control in finite samples (Diebold et Chen (1996)). There has been a number of recent studies (BAI and PERRON, 1998, SHAO and ZHANG, 2010) that seek to improve the reliability of common tests for change-point detection using EDGEWORTH and bootstrap methods. Yet the latter remain approximate.In this companion paper, we propose two tests for change-point detection in linear regression contexts. The first is a Monte Carlo (MC) test for one change-point. The second is a new sequential test for detecting one or more change-point in time series. The finite-sample behaviour of the proposed tests is investigated through Monte Carlo experiments. The results show that tests which are widely used in the studies dealing with climatic changes in West and Central Africa exhibit important size distortions, while MC test achieve complete size control and display good power.

Le prieuré San Samonta à Saint-Montan (Ardèche, France). Analyse archéologique du bâti des édifices cultuels

L'intérêt patrimonial de l'église priorale de San Samonta est souligné dès 1910 par son classement au titre des Monument Historique. L'édifice est malgré tout méconnu. Il est composé de deux bâtiments distincts : une église principale dédiée à saint Montan et une chapelle dédiée à Saint-Jean-Baptiste. Quelques notices anciennes datent la première du XIIe siècle et la seconde du XIe siècle. Toutefois, le déroulé du chantier de construction de ces édifices n'a pas été étudié. Ainsi, à l'aune de l'archéologie du bâti, nous proposons de nouvelles hypothèses sur la construction de la priorale et sur sa fonction au Moyen Âge.

Une relecture architecturale des vestiges de l’odéon de Vienne

L’odéon de Vienne est un monument mentionné dès le XVIIIe siècle par P. Schneyder évoqué. Il a fait l’objet de plusieurs campagnes de dégagement intermittentes entre 1946 et 1976. Malgré son caractère exceptionnel, il a été peu étudié et les connaissances sur ses vestiges restent lacunaires. Les recherches menées sur l’odéon, réalisées dans le cadre d’une prospection thématique, complètent un travail universitaire de Master 2 (Université Lumière Lyon 2), soutenu en 2022 sous la direction de J.-Ch. Moretti et A. Borlenghi. L’analyse non-intrusive des maçonneries a permis de compléter le plan de l’édifice en s’appuyant sur des comparaisons dans le monde antique. Ce travail a conforté les ressemblances déjà suggérées avec l’odéon de Lyon. Enfin, il a aussi été possible de remettre en question l’hypothèse de deux états de l’édifice de Vienne.

Graded identities for matrix algebras of order two over a finite field

Let $G$ be an arbitrary group and let $\mathbb{F}$ be a finite field. In this paper, we determine bases for the $T_G$-ideals of graded polynomial identities of the algebra $M_2(\mathbb{F})$ for all possible $G$-gradings. The bases obtained consist of finitely many non-trivial graded identities, and are finite whenever $G$ is finite.

Action accessibility in the variety of skew braces

In this paper, we answer negatively to a question posed in the context of the 2025 Oberwolfach Mini-Workshop ``The Yang-Baxter Equation and Representations of Braid Groups'' regarding the existence of split extensions classifiers in the category of skew braces. To this end, we show that the variety of skew braces is not action accessible by investigating the categorical notion of centraliser in the sense of Huq. In light of their intrinsic relationship with skew braces, an analogous result is proven for the variety of post-Lie algebras over a fixed field.

A Categorical Realization of the (2-)Category of Monoids via Sch{ü}tzenberger Categories and Strict Factorization Systems

We construct a category equivalent to the category $\mathbf{Mon}$ of monoids and monoid homomorphisms, based on the Sch{ü}tzenberger category of semigroups and categories with strict factorization systems. This equivalence is then extended to the category $\mathbf{Mon_s}$ of unital semigroups and semigroup homomorphisms. By introducing suitable natural transformations, we turn these equivalences into 2-equivalences between 2-categories. The 2-category $\mathbf{Mon_s^{(2)}}$ constructed this way proves the good one to study Morita equivalence of monoids.

Compositionality in algorithms for smoothing

Backward Filtering Forward Guiding (BFFG) is a bidirectional algorithm proposed in Mider et al. [2021] and studied more in depth in a general setting in Van der Meulen and Schauer [2022]. In category theory, optics have been proposed for modelling systems with bidirectional data flow. We connect BFFG with optics by demonstrating that the forward and backwards map together define a functor from a category of Markov kernels into a category of optics, which is furthermore lax monoidal in the case when the guiding kernels coincide with the generative dynamics

Participatory governance and railway transport planning: what are the challenges for SERMs

Participatory governance, seen as a key lever to guide and legitimize public action in urban planning and mobility, is at the heart of French Metropolitan Regional Express Services (SERM) projects. However, their specificities - service-oriented, multimodal, multiscale and multistakeholder - make their planning more complex, without a theoretical or operational framework being clearly established. This article sheds light on these issues through a critical review of participatory approaches in railway transport planning, whether mandatory or voluntary. It also relies on an in-depth analysis of the Clermont-Auvergne SERM, where focus groups and mapping tools are evaluated for their contribution to co-design. Our review shows that participatory approaches for infrastructure planning, whether mandatory or voluntary, often remain limited to top-down information sharing, with weak integration into project engineering. Voluntary approaches to service planning seem better suited but are rare. For SERM-type projects, despite tools better suited to capture service dynamics and territorial complexity, participation remains uneven and poorly integrated into decision-making. The case study highlights the value of an anticipated, progressive and visual approach, promoting iteration, understanding of the issues, and co-construction of proposals. It also reveals the persistent limitations of innovative geo-governance approaches that hinder co-design: lack of inclusion, weak appropriation, and absence of methodological framework. The proposed recommendations aim to structure an active, reproducible participatory method tailored to multicriteria criteria planning of complex services like SERM, within a dynamic of cross-fertilization between research and action to realize the participatory ambition.

Effects of port positioning in liner shipping networks on port efficiency

This study examines the impact of container ports’ positions within the global maritime network – particularly their degree of centrality – on port efficiency. Using data from 117 maritime routes in 2010, we analyze 85 international ports located in Asia, Europe, and North America. Several indicators derived from network theory, including centrality, clustering, and the maximum distance of a direct maritime link - which captures a port’s ability to serve distant markets - are incorporated into a two-stage Data Envelopment Analysis (DEA) model following the double bootstrap methodology proposed by Simar and Wilson (2007). The results reveal significant regional disparities in port efficiency, with Asian ports – especially those in China – achieving the highest performance levels. The second-stage analysis shows that both centrality and clustering have a positive effect on port efficiency. This latter effect is particularly evident among a North American port community benefiting from shipping lines’ service design choices. Overall, the findings underscore not only the importance of port positioning within the global maritime network but also the influence of port community structures on port efficiency.

Practices of Research Data Management and Sharing. Feedback from four SSH Projects Awarded the Open Science Prize 2025

This article presents a comparative study on four research projects awarded the Open Science Prize 2025 from social sciences and humanities (digital humanities, linguistics, quantitative and longitudinal sociology), focusing on their research data management practices. Based on qualitative interviews, the study examines the types of data produced, management approaches, responsibilities, as well as data sharing and outreach strategies. The analysis is structured around the FAIR principles (Findable, Accessible, Interoperable, Reusable). The results highlight a strong heterogeneity of practices, but also a convergence towards increased professionalization of data management and a gradual integration of open science requirements. Particular attention is paid to the impact of the Open Science Award for Research Data, whose effects appear mainly in terms of recognition, visibility, and consolidation of practices.

Multivalued forbidden numbers of two-rowed configurations -- the missing cases

The present paper considers extremal combinatorics questions in the language of matrices. An $s$-matrix is a matrix with entries in $\{0,1,\ldots, s-1\}$. An $s$-matrix is simple if it has no repeated columns. A matrix $F$ is a configuration in a matrix $A$, denoted $F\prec A$, if it is a row/column permutation of a submatrix of $A$. $\text{Avoid}(m,s,F)$ is the set of $m$-rowed, simple $s$-matrices not containing a configuration of $F$ and $\text{forb}(m,s, F)=\max\{|A|\colon A \in \text{Avoid}(m,s,F)\}$. Dillon and Sali initiated the systematic study of $\text{forb}(m,s, F)$ for $2$-matrices $F$, and computed $\text{forb}(m,s, F)$ for all 2-rowed $F$ when $s>3$. In this paper we tackle the remaining cases when $s=3$. In particular, we determine the asymptotics of $\text{forb}(m,3,p\cdot K_2)-\text{forb}(m,3,p\cdot I_2)$ for $p>3$, where $K_2$ is the $2\times 4$ simple $2$-matrix and $I_2$ is the $2\times 2$ identity matrix, as well as the exact values of $\text{forb}(m,3,F)$ for many 2-rowed $2$-matrices $F$.

On the Multi-Robber Damage Number

We study a variant of the Cops and Robbers game on graphs in which the robbers damage the visited vertices, aiming to maximize the number of damaged vertices. For that game with one cop against $s$ robbers a conjecture was made by Carlson, Halloran and Reinhart that the cop can save three vertices from being damaged as soon as the maximum degree of the base graph is at least $\binom{s}{2} + 2$. We are able to verify the conjecture and prove that it is tight once we add the assumption that the base graph is triangle free. We also study the game without that assumption, disproving the conjecture in full generality and further attempting to locate the smallest maximum degree of a base graph which guarantees that the cop can save three vertices against $s$ robbers. We show that this number is between $2\binom{s}{2} - 3$ and $2\binom{s}{2} + 1$. Furthermore, after the game has been previously studied with one cop and multiple robbers, as well as with one robber and multiple cops, we initiate the study of the game with two cops and two robbers. In the case when the base graph is a cycle we determine the exact number of damaged vertices. Additionally, when the base graph is a path we provide bounds that differ by an additive constant.

Potential of biochars from agricultural residues in domestic wastewater treatment using vertical flow filters vegetated with Echinochloa pyramidalis.

The treatment of domestic wastewater by vegetated filters is proposed as an alternative better suited to the socio-economic conditions of developing countries. The use of biochar in these filters in partial or total substitution of conventional filter substrate was the main aim of the present study. The effectiveness of three biochars produced from three crop wastes (Corn cobs, coconut shells and palm nut shells) in improving the purification performance of vertical flow filters vegetated with antelope grass was studied. The experimental set-up consisted of three biochar filters plus a control replicated thrice. The filters were supplied at a hydraulic loading rate of 142 l/m2/jr. The physi-co-chemical characteristics of the water were measured 30 and then 60 days from the beginning of the test; the physical growth parameters of randomly selected plants were measured weekly between the 30th and the 60th day, i.e. 4 times. The results reveal an increase in pH, an improvement in the reduction of nitrogen, iron, phosphorus, and microbes content effluents from biochar filters compared to those from conventional sand filters. Overall, the corn cob biochar filter showed better results after two months. It remains important for future studies to monitor the parameters over a longer period and to test the effect of the combination of the three biochars in one filter.

Method for quantifying urban mine flows: the case of clay bricks in Ile-de-France

The building sector is a large consumer of resources and a major producer of waste. In a context of resource depletion, the building sector will have to implement strategies to become more circular. One possible solution is to resort to urban mining, i.e., to see existing buildings as a resource pool available for future construction or renovation of the building stock during their deconstruction or renovation. This article proposes a method to compare the quantities generated by deconstruction and renovation to the needs of new construction or renovation projects. After deconstruction, building components may be suitable for various secondary uses from reuse to recycling. The uses issued from reuse and recycling are identified and the quantities of materials corresponding to each of them are determined with adequate units (m2, kg...) to be compared with the new buildings’ project’s needs. These units facilitate the comparison between the recovered materials and the demand of components and materials. The method assumes that circular economy is fully developed and that the focus is only on the technical feasibility of recovery methods, ignoring the socio-economic obstacles to reuse and recycling. To illustrate the method, the case of clay bricks in Ile-de-France is detailed. During the year 2020, 153 kt of clay bricks were produced by the demolition of buildings in this territory, allowing to obtain, for example, a maximum surface of more than 21,000 m2 of masonry bricks, in reuse, and 9.2 kt of aggregates for concrete manufacturing.

The Functional Machine Calculus III: Control

The Functional Machine Calculus (Heijltjes 2022) is a new approach to unifying the imperative and functional programming paradigms. It extends the lambda-calculus, preserving the key features of confluent reduction and typed termination, to embed computational effects, evaluation strategies, and control flow operations. The first instalment modelled sequential higher-order computation with global store, input/output, probabilities, and non-determinism, and embedded both the call-by-name and call-by-value lambda-calculus, as well as Moggi's computational metalanguage and Levy's call-by-push-value. The present paper extends the calculus from sequential to branching and looping control flow. This allows the faithful embedding of a minimal but complete imperative language, including conditionals, exception handling, and iteration, as well as constants and algebraic data types. The calculus is defined through a simple operational semantics, extending the (simplified) Krivine machine for the lambda-calculus with multiple operand stacks to model effects and a continuation stack to model sequential, branching, and looping computation. It features a confluent reduction relation and a system of simple types that guarantees termination of the machine and strong normalization of reduction (in the absence of iteration). These properties carry over to the embedded imperative language, providing a unified functional-imperative model of computation that supports simple types, a direct and intuitive operational semantics, and a confluent reduction semantics.

Traces via Strategies in Two-Player Games

Traces form a coarse notion of semantic equivalence between states of a process, and have been studied coalgebraically for various types of system. We instantiate the finitary coalgebraic trace semantics framework of Hasuo et al. for controller-versus-environment games, encompassing both nondeterministic and probabilistic environments. Although our choice of monads is guided by the constraints of this abstract framework, they enable us to recover familiar game-theoretic concepts. Concretely, we show that in these games, each element in the trace map corresponds to a collection (a subset or distribution) of plays the controller can force. Furthermore, each element can be seen as the outcome of following a controller strategy. Our results are parametrised by a weak distributive law, which computes what the controller can force in a single step.

Des croquis comme support de raisonnement et de changement de registres

We are convinced of the usefulness of sketches and diagrams during mathematical work but the observation is made in our practices that they are not spontaneously used by students. In order to study the understanding and use of sketches by mathematics students, we designed and then proposed a test at different university levels. The test consists of five exercises.The first concerns different representation registers of a set of numbers, the second on a graphic proof of an implicative algebraic proposition and the last three on the graphic approch to the notions of injectivity, surjectivity, bijectivity in the context of the analysis. The sketches, proposed or requested in each exercise, are intended to be aids to changes of register and reasoning. We present what motivated the choices and developments of the exercises then we analyze the results of these tests. In each case, we see difficulties in understanding and the sketches proposed, which leads to think that the sketch must be the subject of specific work at the university level.

Peer assessment in mathematics: activity of students evaluating proofs

This article deals with peer-assessment in the context of higher education teaching in mathematics, and examines the nature of student activity when assessing work,more precisely proofs, produced by peers. After an overview of research on peer assessment, we propose an experiment with students in a specific post-secondary scientific class, and analyze the activity of the students involved. Our analyses are based on a priori analyses of the proposed tasks and tools from research on students personal mathematical work. We base on written notes of assessments, observations of pairs in assessment situations, and answers to a questionnaire on the perception of their activity. We have identified some specific student activities during the peer assessment process, in particular related to the analysis and correction of proofs, but also to the awareness of the issues associated with evaluation. This enables us to argue for the potential of peer assessment in higher mathematics education.

Bloch-Ogus theory for smooth and semi-stable schemes in mixed characteristic

We study Bloch-Ogus theory and the Gersten conjecture for homology theories with duality satisfying certain properties, in particular for étale cohomology with finite coefficients coprime to the residue characteristic of the base, for smooth and semi-stable schemes in mixed characteristic. We prove the Gersten conjecture in the smooth case and prove a special case in the semi-stable situation. As a corollary of the smooth case, we obtain the surjectivity of the Galois symbol map for arbitrary local rings over an excellent discrete valuation ring.

G3-Criteria and Applications

The G3-property of a subvariety was introduced by Hironaka-Matsumura, and plays an important role for deducing connectedness and extension results. Unfortunately, it's a rather elusive notion, which is not always easy to establish. Most of the existing work is concentrated on subvarieties of homogeneous varieties. The first goal of this article is to show that mobility assumptions on the subvariety, considered in works of Badescu, Chow, Debarre, Voisin, yield a certain partial positivity property, slightly stronger than G3, previously introduced by the author. Second, we apply the result to prove that, in numerous situations, the splitting of the normal bundle of a smooth two-codimensional subvariety implies that it is a complete intersection.

Management of diagnostic uncertainty in teleconsultation by General Practitioners (GPs) in primary care

IntroductionDiagnostic uncertainty is ubiquitous in general practice. General practitioners perceive it more frequently duringteleconsultations, where the clinical reasoning process is altered, the physician physician-patient relationship is disrupted, and physica lexamination is limited or absent. In 2020, general practitioners feared that teleconsultations would increase diagnostic unce r-tainty, yet no study had explored how diagnostic uncertainty is managed in this context.ObjectivesTo identify the sources and consequences of diagnostic uncertainty and to explore how general practitioners man-age diagnostic uncertainty in teleconsultations.MethodsAn inductive qualitative study based on semi semi-structured individual interviews was conducted using an interviewguide. Sampling began through networking, then was purposive as interviews progressed until data saturation was reached.Two researchers performed an inductive thematic content analysis.Results: Fifteen interviews approached data saturation. Diagnostic uncertainty was greater in teleconsultations and generatednegative emotional experiences among general practitioners, including worry, frustration, and dissatisfaction. Inappropriateconditions for teleconsultations and difficulties in identifying or interpreting symptoms via video contributed to this uncer tai nty.In response, general practitioners adapted their diagnostic approach by adopting a more exhaustive process, which some-times led to over over- or under under-prescribing and the arrangement in in-person consultations. They also involved patients by explicitlyexpressing their diagnostic uncertainty , instructing them on warning signs, and providing guidance based on symptom evolu-tion.Conclusion: To manage diagnostic uncertainty in teleconsultations, general practitioners modified their usual reasoning pro-cess, tended to over over-prescribe, and arranged in in-person consultations. While the exhaustive diagnostic approach compensatesfor uncertainty, it may also be more resource resource-intensive and less aligned with evidence evidence-based medicine.

Characteristics of patients receiving a prescription for adapted physical activity in Aubervilliers: a retrospective study

physical activity identified in the study was the desire for good mental, physical, and social health¹⁰. Due to its sustainable nature, this program, a pioneer in France since 2015, seemed conducive to studying adherence to an adapted physical activity program.The main objective of the study was to describe the sociodemographic profile of patients benefiting from this program since its creation in 2015. The secondary objective was to compare the profile of patients who received an APA prescription under this program but never attended any session with those who attended multiple sessions.METHOD Study Type and PopulationA retrospective observational study was conducted. The study population consisted of adult patients who consulted at the Aubervilliers CMS and who had received a prescription under the "exercise on prescription" program.The city of Aubervilliers is in Seine-Saint-Denis (93), a department with an over-representation of cardiovascular diseases and social precarity¹¹. The "exercise on prescription" program was created in 2015 at the Aubervilliers CMS in partnership with the municipality. It is free for beneficiaries. Initially, the GP identifies the indication, proposes it to the patient, and prescribes it. The prescribing physicians for APA could be GPs from the CMS and some private GPs in Aubervilliers who were partners in the program. The patient is then registered, and the contact details of the sports educator are provided to them.

The sports educator has validated training as a level 2 health-sport animator from the Île-de-France Regional Olympic and Sports Center. They offer an interview during which they assess the patient's functional abilities, then specify the modalities of the APA sessions, with the possibility of attending one or more weekly sessions, with multiple time slots during the week and several activities (yoga, muscle strengthening, aquagym). The number of sessions is not predetermined and depends on the participant.

Data Collection Methods

All patients who received an APA prescription from a GP practicing at the Aubervilliers CMS since the creation of the program were included in the study, regardless of whether they resided in Aubervilliers. In 2024, the Aubervilliers CMS had 6 full-time equivalent (FTE) GPs.

The theory of reachability in trace-pushdown systems

We consider pushdown systems that store, instead of a single word, a Mazurkiewicz trace on its stack. These systems are special cases of valence automata over graph monoids and subsume multi-stack systems. We identify a class of such systems that allow to decide the first-order theory of their configuration graph with reachability. This result complements results by D'Osualdo, Meyer, and Zetzsche (namely the decidability for arbitrary pushdown systems under a severe restriction on the dependence alphabet).

Paired Disjunctive Domination Number of Middle Graphs

The concept of domination in graphs plays a central role in understanding structural properties and applications in network theory. In this study, we focus on the paired disjunctive domination number in the context of middle graphs, a transformation that captures both adjacency and incidence relations of the original graph. We begin by investigating this parameter for middle graphs of several special graph classes, including path graphs, cycle graphs, wheel graphs, complete graphs, complete bipartite graphs, star graphs, friendship graphs, and double star graphs. We then present general results by establishing lower and upper bounds for the paired disjunctive domination number in middle graphs of arbitrary graphs, with particular emphasis on trees. Additionally, we determine the exact value of the parameter for middle graphs obtained through the join operation. These findings contribute to the broader understanding of domination-type parameters in transformed graph structures and offer new insights into their combinatorial behavior.

Vanishing Coefficient Results in Three Families of Infinite q-products

In the recent past, the work in the area of vanishing coefficients of infinite $q$-products has been taken to the forefront. Weaving the same thread as Ramanujan, Richmond, Szekeres, Andrews, Alladi, Gordon, Mc Laughlin, Baruah, Kaur, Tang, we further prove vanishing coefficients in arithmetic progressions moduli 5, 7, 11, 13, 17, 19 and 29 of the following four families of infinite products, where $\{X_{a,b,sm,km,u,v}(n)\}_{n\geq n_0}$, $\{Y_{a,b,sm,km,u,v}(n)\}_{n\geq n_0}$ and $\{Z_{a,b,sm,km,u,v}(n)\}_{n\geq n_0}$ are defined by\begin{align*}\sum_{n\geq n_0}^{\infty}X_{a,b,sm,km,u,v}(n)q^n:=&\p(q^{a},q^{sm-a};q^{sm})^u\p(q^{b},q^{km-b};q^{km})^v, \\\sum_{n\geq n_0}^{\infty}Y_{a,b,sm,km,u,v}(n)q^n:=&\p(q^{a},q^{sm-a};q^{sm})^u\p(-q^{b},-q^{km-b};q^{km})^v, \\\sum_{n\geq n_0}^{\infty}Z_{a,b,sm,km,u,v}(n)q^n:=&\p(-q^{a},-q^{sm-a};q^{sm})^u\p(q^{b},q^{km-b};q^{km})^v,\end{align*}here $a, b, s, k, u$ and $v$ are chosen in such a way that the infinite products in the right-hand side of the above are convergent and $n_0$ is an integer (possibly negative or zero) depending on $a, b, s, k, u$ and $v$. The proof uses the Jacobi triple product identity and the properties of Ramanujan general theta function.

Modular transform of free fermion generalised Gibbs ensembles and generalised power partitions

In [1] a conjecture for the modular transformation of the free fermion generalised Gibbs ensemble (GGE) was given where only the KdV charge associated to the weight four quasi primary field was inserted. In this paper we first generalise this conjecture to the case with an arbitrary, finite collection of KdV charges in the GGE. These GGEs are generalisations of the generating function of power partitions. We prove the conjectured transformation for the case with a finite number of charges inserted and discuss the case with an infinite number of charges.

Quantifying Shakespeare's Iambic Pentameter: A Metric Variability Analysis

This study develops and evaluates a computational framework for quantifying the metrical organization of Shakespeare's complete sequence of 154 sonnets. Rather than treating poetic metre as a collection of individually interpreted deviations, the framework models the relationship between lexical stress and iambic pentameter as a reproducible binary sequential structure. The corpus comprises 2,155 poetic lines, subjected to pronunciation normalization, Early Modern English correction, lexical-stress extraction, alternative metrical alignment, and minimum-deviation optimization. Automated stress assignment achieves 95.1\% agreement with independently verified annotations, providing a validated basis for subsequent corpus-level analysis. The resulting metrical representations are examined through deviation-density measures, Shannon entropy, position-specific entropy, first-order Markov transitions, principal component analysis, hierarchical clustering, recurrence analysis, and Monte Carlo hypothesis testing. The empirical results reveal a metrical system characterized by strong regularity without mechanical uniformity. Deviations exhibit pronounced positional heterogeneity, while the transition from deviation to metrical agreement occurs with probability 0.8778, indicating strong local recovery following departures from the reference pattern. Multivariate analysis shows that metrical variability is distributed across multiple dimensions rather than governed by a single latent factor: the first five principal components explain 58.40\% of variance and the first nine explain 93.35\%. Hierarchical clustering identifies a dominant metrical profile comprising 82.69\% of poetic lines alongside smaller rhythmic substructures. Most strikingly, only 174 distinct binary configurations occur across the 2,155 lines, with the observed recurrence rate of 0.020656 approximately ten times the 0.002042 mean generated by the specified randomized null model ($p<0.0001$). These findings provide quantitative evidence that Shakespearean metre is neither rigidly mechanical nor randomly variable. Instead, it exhibits a structured interaction of constraint, sequential dependence, recurrent rhythmic configurations, and continuous variation. The proposed framework transforms metrical organization into a reproducible computational object while retaining its connection to historical pronunciation and traditional prosodic scholarship, and provides a transferable methodology for quantitative studies of poetic form across authors, periods, and verse traditions.

Dialect Cartography of Erzya and Moksha Languages: Digitized Historical Sources and Evaluation of the Contemporary Data

This study investigates the correspondences between a recent map of Uralic languages that also covers the Erzya and Moksha languages in detail. We discuss our point of view in linguistic cartography more generally, but especially within the context of Uralic languages, and address various difficulties that can be recognized in defining the speaker area boundaries and choosing settlements that should be included in the traditional or contemporary speech communities. We use the historical data of Heikki Paasonen, which, we believe, is a highly reliable indicator of at least some areas that should be included in the traditional distributions of these languages as points of comparison. This data is contrasted with the contemporary language maps.

LURK: Lambda, the ultimate recursive knowledge: (Experience Report)

We introduce Lurk, a new LISP-based programming language for zk-SNARKs. Traditional approaches to programming over zero-knowledge proofs require compiling the desired computation into a flat circuit, imposing serious constraints on the size and complexity of computations that can be achieved in practice. Lurk programs are instead provided as data to the universal Lurk interpreter circuit, allowing the resulting language to be Turing-complete without compromising the size of the resulting proof artifacts. Our work describes the design and theory behind Lurk, along with detailing how its implementation of content-addressing can be used to sidestep many of the usual concerns of programming zero-knowledge proofs.

Classifying Prime Character Degree Graphs With Eight Vertices

In this paper, an effort is made to classify which prime character degree graphs having eight vertices occur for some finite solvable group. To approach this, we compile known results and constructions from the literature which are used to develop a general algorithm to begin classifying graphs of any order. We then apply the algorithm to the graphs of order eight. Of the 12,346 non-isomorphic graphs with eight vertices, 1,229 are disconnected and are fully classified. Meanwhile, thirty-seven of the 11,117 non-isomorphic connected graphs are shown to occur; thirty-four of which are constructed via joins of smaller graphs and three of which have diameter three. Fifty-eight graphs are shown not to occur, several of which fall into previously studied families, while the classification of 204 graphs is still unknown.

Geospatial challenges for urban projects environmental impact assessment

Reducing the environmental impact of the building stock (construction, use, rehabilitation, end of life) is essential in order to achieve a sustainable rate of consumption of the planet's resources. Life cycle analysis (LCA) enables stakeholders to assess several categories of impact of an urban project (damage to human health, damage to biodiversity, etc.) in order to make the most sober choices. This assessment requires a large amount of data that is as representative as possible of the concerned territories. In view of the difficulties encountered in taking into account the geographical dimension, an exploratory interdisciplinary project has been launched to identify spatial challenges to overcome when carrying out a LCA of an urban project. This article presents the initial results of the project, beginning with a description of the issues involved in the spatialization of LCA, followed by a description of some of the challenges encountered more specifically in the context of LCA of urban projects. The aim is to help define a research programme to improve the way in which the geographical dimension is taken into account in the LCA of urban projects, and to inform the geospatial scientific community of the problems encountered by environmental assessment researchers working to provide professional communities with robust and reliable LCA methods and tools.

Process of change: states, transitions, and determinants

The goal of persuasion is to change the behaviour or the attitude of a person without using any form of coercion (Oinas et al. 2010). In the last ten years, several models, approaches and theories have been developed in the research field of persuasion, producing a copious scientific literature. Different reviews of the state-of-the-art focusing on specific aspects have been proposed. Pindel et al.

Adaptation for sustainable persuasion

Making people change is difficult; making them change for ever is all the more challenging. We explore adaptation as a means for bringing diversity and thereby for killing the annoying effect of persuasive messages. The case study is TILT, a persuasive application dedicated to smartphone usage regulation. We show that adapting persuasion increases efficiency.

Bilevel Optimization of the Kantorovich Problem and its Quadratic Regularization Part III: The Finite-Dimensional Case

As the title suggests, this is the third paper in a series addressing bilevel optimization problems that are governed by the Kantorovich problem of optimal transport. These tasks can be reformulated as mathematical problems with complementarity constraints in the space of regular Borel measures. Due to the nonsmoothness that is introduced by the complementarity constraints, such problems are often regularized, for instance, using entropic regularization. In this series of papers, however, we apply a quadratic regularization to the Kantorovich problem. By doing so, we enhance its numerical properties while preserving the sparsity structure of the optimal transportation plan as much as possible. While the first two papers in this series focus on the well-posedness of the regularized bilevel problems and the approximation of solutions to the bilevel optimization problem in the infinite-dimensional case, in this paper, we reproduce these results for the finite-dimensional case and present findings that go well beyond the ones of the previous papers and pave the way for the numerical treatment of the bilevel problems.

A trust-region method for optimal control of ODEs with continuous-or-off controls and TV regularization

A solution algorithm for a special class of optimal control problems subject to an ordinary differential equation is proposed. The controls possess a continuous-or-off structure and are priced by a convex function. Additionally, a total variation regularization is applied to penalize switches. Our solution method combines a trust-region method and a proximal gradient method. The subproblems are solved via Bellman's optimality principle. Convergence with respect to a criticality measure is proven. As a numerical example, we solve a simple optimal control problem involving an SIR model.

Construction of pre-and post-Lie algebras for stochastic PDEs

We give and study a construction of pre-Lie algebra structures on rooted trees whose edges and vertices are decorated, with a grafting product acting, through a map $ϕ$, both on the decoration of the created edge and on the vertex that holds the grafting. We show that this construction gives a pre-Lie algebra if, and only if, the map $ϕ$ satisfies a commutation relation, called tree-compatibility. We show how to extend this pre-Lie algebra structure to a post-Lie one by a semi-direct extension with another post-Lie algebra. We also define several constructions to obtain tree-compatible maps, and give examples, including a description of all tree-admissible maps when the space of decorations of the vertices is $2$-dimensional and the space of decorations of the edges is finite-dimensional. A particular example of such a construction is used by Bruned, Hairer and Zambotti for the study of stochastic partial differential equations: when no noise is involved, we show that the underlying tree-compatible map is the exponential of a simpler one and deduce an explicit isomorphism with a classical pre-Lie algebra of rooted trees; when a noise is involved, we obtain the underlying tree-compatible map as a direct sum. We also obtain with our formalism the post-Lie algebras described by Bruned and Katsetsiadis.

An interdisciplinary essay on theories of the firm and organization.

This study examines the relationship among economics, strategic management, organizational studies, and economic sociology-four interconnected fields concerned with firms and organizations-from an interdisciplinary perspective. The argument is advanced that a descriptive approach, rather than a prescriptive one, more effectively illuminates their interactions. Recent natural and spontaneous interactions are highlighted as valuable for evaluating the effectiveness of interdisciplinary engagement. This perspective is grounded in three observations about major developments in these disciplines over the past fifty years. First, while all four fields focus on firms and organizations, they frequently operate in isolation despite overlapping interests. Second, the interactions among these disciplines should be analyzed with reference to the philosophical foundations of interdisciplinarity, particularly the ways in which disciplinary boundaries, methodological assumptions, and epistemological traditions shape knowledge production. Third, the study investigates the extent to which these interdisciplinary interactions contribute to the accumulation of knowledge. Ultimately, it is argued that adopting the complexity perspective is the most effective means of fostering interdisciplinary relationships, as it balances autonomy and collaboration, promotes pluralism, and supports authentic interdisciplinary work.

Messianic Economics. The Entrepreneur as the Agent of Uncertain Futures in Modern Economic Ecosystems

Economic innovation and transformation are future-oriented fields where financial risk-return and economic growth considerations permeate with visions of technological progress and cultural determinants of human behavior. This case study about the evolution of the entrepreneurial persona in the history of economic thought demonstrates how narrative research can contribute to understanding the growth dynamics of economic ecosystems. Rather than being indicators of flaws in otherwise rational economic processes, narrative twists and turns reflect the institutional and cultural preconditions of economic growth and innovation.

Since the early days of industrialization, economic thought takes recourse to the institutional persona of the entrepreneur to explain dynamics of innovation and transformative growth. The descriptions of the entrepreneur in the works of Robert Cantillon, Joseph Schumpeter and Frank Knight show how the parameters of innovation, cristallized in the features of entrepreneurial activity, change along the trajectories of, and reflect, industrial and economic development. What these descriptions have in common are the fundamental features of innovative activity in otherwise steady economic ecosystems: the ability to embrace the uncertainty of a future venture through an informed view about future market demand; the stamina to impose change to incumbent structures and processes; and the acumen to mobilize ample financial funding to realize an innovative venture.

The current debate around artificial intelligence and its potential to generate unprecedented future growth goes along with a messianic turn in the discourse about entrepreneurial activity. In the current debate about AI-led innovation, the entrepreneurial narrative, unchanged at its core, takes on a quasi-spiritual dimension. Entrepreneurs appear as saviour-like personae, able to break through a state of general stagnation and decline in order to enable not less than a new, technology-fuelled chapter for humanity. While the jury is out whether this scenario will unfold, the messianic turn of the entrepreneurial discourse shows that the instruments of mainstream economics do not seem to be suited to assess the growth dynamics of AI-led innovation. To assess this messianic turn of the entrepreneur and its bearings for future economic growth trajectories, a narrative turn in economic research appears warranted.

The core-mantle mode of gravitational oscillation

We present the characteristics of a mode of axial oscillation between Earth's mantle, fluid core and solid inner core that has not been previously reported. The mode involves a quasi-rigid rotation of the fluid core outside the tangent cylinder (TC) exchanging its angular momentum with the mantle via a three step process. First, by a magnetic torque with the fluid inside the TC; second by a magnetic torque between the latter and the inner core; and finally by a gravitational torque between the inner core and mantle. Although the gravitational torque is purely between the mantle and inner core, the mode involves an oscillation of the whole of the core, and we refer to it as the core-mantle gravitational (CMG) mode. This form of gravitational oscillation occurs when the magnetic field within the core is sufficiently strong that the propagation time of Alfvén waves is shorter than the mode period, which is the case for Earth. We show how the period, quality factor $Q$ and structure of the CMG mode depends on the strength of the gravitational torque and viscous relaxation time $\tau_i$ of the inner core. For Earth, the CGM mode period should be in the range of 40 to 100 years, but viscous relaxation of the inner core likely implies a small $Q$, below 1 if $\tau_i<10$ years. Our results suggest that the CMG mode may act to amplify resonantly, though only modestly, multi-decadal changes in the length of day driven by zonal accelerations in the fluid core.

Using paleomagnetic observations and geodynamo simulations to assess Earth's magnetic field morphology and variability

Multiple strategies have been suggested for quantitatively comparing numerical dynamo simulations to geomagnetic field models and paleomagnetic observations. Observationally-constrained metrics are designed to infer properties of simulations that are required to produce Earth-like behaviour and enable inferences on otherwise inaccessible properties of the geomagnetic field, such as its long-term spatio-temporal behaviour at the core-mantle boundary. However, these criteria are derived from data spanning differing timescales with fundamentally different spatio-temporal resolution, are often applied in isolation, and may not be independent assessments, so that holistic syntheses of simulated and observed field variations are currently lacking. In this work, we apply 14 existing criteria measuring field morphological and variability properties on centennial to million-year timescales to a database of 207 dynamos. Individual metrics are matched over various ranges of core-mantle boundary dipolarity (𝑓𝑑 ) and its temporal variability (𝛿 𝑓𝑑 ), though no single range conforms with all proposed metrics. The greatest overlap between simulations matching disparate criteria occurs for 𝑓𝑑 = 0.50−0.64, which is lower than the modern field value of 0.65−0.71 (1900-2025). Earth-like dynamos tend to have magnetic/kinetic energy ratio >1, consistent with a MAC force balance, and require a magnetic Reynolds number 𝑅𝑚 = 750−1200 to match the secular variation timescale. Simulations in our dataset exhibit reduced temporal variability at moderate dipolarity (𝑓𝑑 ∼ 0.5) compared to inferences from global field models, which hinders their capacity to produce Earth-like polarity reversals. This is a correction of the original manuscript where the 𝑓𝑑 value in 2025.0 was incorrectly stated. We thank Julien Aubert for his careful reading and suggestion which is now incorporated.

One-dimensional elastoplastic models with isotropic hardening as differential inclusions in primal form

To improve the numerical simulation of rockfall protection barriers, this work addresses an extension of a one-dimensional model for elastoplasticity using a friction element and a spring in series, to include isotropic hardening and unilateral behavior. We reformulate the resulting system of differential inclusions in primal form and develop a timestepping scheme via an extended version of Moreau's midpoint rule. The scheme handles nonsmooth dynamics consistently, allowing to include frictional contact and impacts. The results provide a rigorous and implementable framework for simulating coupled elastoplastic frictional contact systems, contributing to the analysis and computation of nonsmooth rate-independent processes.

A mixed Petrov-Galerkin Cosserat rod finite element formulation

This paper presents a total Lagrangian mixed Petrov-Galerkin finite element formulation that provides a computationally efficient approach for analyzing Cosserat rods that is free of singularities and locking. To achieve a singularity-free orientation parametrization of the rod, the nodal kinematical unknowns are defined as the nodal centerline positions and unit quaternions. We apply Lagrange interpolation to all nodal kinematic coordinates, and in combination with a projection of non-unit quaternions, this leads to an interpolation with orthonormal cross-section-fixed bases. To eliminate locking effects such as shear locking, the variational Hellinger-Reissner principle is applied, resulting in a mixed approach with additional fields composed of resultant contact forces and moments. Since the mixed formulation contains the constitutive law in compliance form, it naturally incorporates constrained theories, such as the Kirchhoff-Love theory. This study specifically examines the influence of the additional internal force fields on the numerical performance, including locking mitigation and robustness. Using well-established benchmark examples, the method demonstrates enhanced computational robustness and efficiency, as evidenced by the reduction in required load steps and iterations when applying the standard Newton-Raphson method.

Structural Liveness of Conservative Petri Nets

We show that the EXPSPACE-hardness result for structural liveness of Petri nets [Jancar and Purser, 2019] holds even for a simple subclass of conservative nets. As our main result, we prove that for structurally live conservative nets, the values of the minimal live markings are at most doubly exponential in the size of the net. This implies the EXPSPACE-completeness of structural liveness for conservative Petri nets. The result also applies to structurally bounded Petri nets, whereas the complexity of the general case remains open. As a proof ingredient of independent interest, we present an extension of known results on the bounds of minimal integer solutions to Boolean combinations of linear equalities, inequalities, and divisibility constraints.

Loops, Inverse Limits and Non-Determinism

We introduce an operator on problems in Weihrauch complexity, which we call the infinite loop or inverse limit, and which corresponds to an infinite compositional product. This operation arises naturally whenever one implements algorithms that produce a sequence of results in an infinite loop, using some fixed subroutine. We prove that the corresponding operator is monotone with respect to (strong) Weihrauch reducibility but that it is not a closure operator. One of our findings is that weak KÅ‘nig's lemma is closed under infinite loops, which implies that the class of non-deterministically computable problems is also closed under this operation. Consequently, this class allows for a high degree of flexibility in programming. As our main technical tools, we present an injective version of the recursion theorem and an infinitary version of the so-called independent choice theorem. We also show that, in general, the infinite loop operator is more powerful than the composition of the diamond operator followed by the parallelization operator. However, in many practical scenarios, these compositions yield a result, which coincides with the application of the infinite loop operator. Finally, we discuss the special situation of loops for single-valued problems and for problems on Turing degrees.

Nonparametric estimation of the jump rate in mean field interacting systems of neurons

We consider finite systems of $N$ interacting neurons described by non-linear Hawkes processes in a mean field frame. Neurons are described by their membrane potential. They spike randomly, at a rate depending on their potential. In between successive spikes, their membrane potential follows a deterministic flow. We estimate the spiking rate function based on the observation of the system of $N$ neurons over a fixed time interval $[0,t]$. Asymptotic are taken as $N,$ the number of neurons, tends to infinity. We introduce a kernel estimator of Nadaraya-Watson type and discuss its asymptotic properties with help of the deterministic dynamical system describing the mean field limit. We compute the minimax rate of convergence in an $L^2 -$error loss over a range of Hölder classes and obtain the classical rate of convergence $ N^{ - 2β/ ( 2 β+ 1)} , $ where $ β$ is the regularity of the unknown spiking rate function.

A sub-Riemannian model of neural states in the primary motor cortex

We develop a neurogeometric model for the arm area of motor cortex, which encodes complex motor primitives, ranging from simple movement features like movement direction, to short hand trajectories, termed fragments, and ultimately to more complex patterns known as neural states (Georgopoulos, Hatsopoulos, Kadmon-Harpaz et al). Based on the sub-riemannian framework introduced in 2023, we model the space of fragments as a set of short curves defined by kinematic parameters. We then introduce a geometric kernel that serves as a model for cortical connectivity and use it in a differential equation to describe cortical activity. By applying a grouping algorithm to this cortical activity model, we successfully recover the neural states observed in Kadmon-Harpaz et al, which were based on measured cortical activity. This confirms that the choice of kinematic variables and the distance metric used here are sufficient to explain the phenomena of neural state formation. The modularity of our model reflects the brain's hierarchical structure, where initial groupings in the kinematic space $\mathcal{M}$ lead to more abstract representations. This approach mimics how the brain processes stimuli at different scales, extracting both local and global properties.

Femwashing in Women’s Sports: When Commitment Fades After Competition

This article introduces the concept of femwashing within the field of sports marketing and corporate social responsibility (CSR). The term, which first appeared in online usage in 2017 and has been mobilized in academic research since 2022-2023 (Haggren, 2022; Walters, R. 2022), follows the trajectory of other “washing” practices such as greenwashing (Delmas & Burbano, 2011; Lyon & Montgomery, 2015) or pinkwashing (King, 2006). We define femwashing as the opportunistic display of egalitarian commitments without sustainable organizational transformation or structural support for women.Based on a qualitative analysis of emblematic campaigns (Adidas, Nike, Visa, Orange), we highlight a typology of femwashing in sports, structured into three forms: event-based, stereotypical, and organizational. Beyond being a simple extension of existing washings, femwashing serves as an analytical lens for examining the relationship between media visibility and CSR governance.From a theoretical perspective, it enriches the taxonomy of washing practices and bridges two domains that have remained largely siloed: CSR and sports sponsorship. From a managerial perspective, it questions organizational authenticity and opens new avenues for innovation in corporate engagement with women’s sports.

Analysis of values in the statutes of sports clubs: The case of clubs in Ticino and Vaud

This study examines how sports clubs in the Swiss cantons of Ticino and Vaud integrate ethical and social values into their governance by analysing their statutes. Sports clubs, as central actors in youth socialization, serve as key venues for the dissemination of values. The aim is to assess the extent to which these values are formalized, made explicit, and aligned with the Swiss Olympics’ Ethics Charter.A total of 190 statutes from clubs affiliated with various federations were analysed using a qualitative approach (MAXQDA). The coding framework was based on the values promoted by the International Olympic Committee (IOC), UNESCO, and Swiss Olympic.The results show that the promotion of sport (160 mentions) and team spirit (83 mentions) are the most frequent themes, while moral and ethical principles are less commonly cited (41 mentions). The complete absence of the verb “to transmit,” despite its centrality in the Ethics Charter, reveals a lack of formalization in how values are conveyed. Ticino clubs more frequently reference the Ethics Charter, whereas Vaud clubs place greater emphasis on fair play and anti-doping measures.These findings highlight a gap between the recognition of values and their practical implementation. To enhance the effective transmission of values to young athletes, it is necessary to harmonize the drafting of statutes, introduce training initiatives, and include monitoring mechanisms.

Integration of PDEs via C∞-structures

Following classical method of differential constraints, interpreted in jet space, we present a constructive procedure for the integration of partial differential equations (PDEs). The approach consists of adjoining compatible auxiliary equations to reduce the PDE to a finitetype system in which the Vessiot distribution becomes involutive on an open set. Rather than classical solvable structures, we employ C∞-structures of distributions, a generalization with relaxed bracket conditions that are systematically easier to construct, yet still guarantee integration through successive Pfaffian equations. Three explicit examples illustrate the method: the linear wave equation with affine constraints, the Liouville equation, and a non-trivial rational nonlinear PDE. In every case the procedure yields an explicit family of solutions.

Volterra-Bogoyavlensky lattices and solutions of $A_{2n}^{(1)}$ invariant Painlevé equations

The objective of this work is to develop a framework that exploits the lattice structure of the $k$-th Volterra--Bogoyavlensky equations ($k\in\mathbb N$, $k>1$) to generate rational solutions of higher symmetric Painlevé equations. For $k=2$, we show that the Volterra lattice, equipped with suitable initial conditions, exactly models the one- and two-dimensional orbits generated by half-translation operators of the $A_2^{(1)}$ symmetric Painlevé IV equations. This correspondence yields explicit closed-form expressions for all solution components in terms of generalized Okamoto polynomials and leads to new algebraic recurrence relations among these polynomials. We present two generalizations of the above Volterra lattice. One is derived from a fractional translation of the $A_{4}^{(1)}$ symmetric Painlevé equations. It generalizes Volterra lattice structure in the multi-component setup of the affine $A_{4}^{(1)}$ group and it is shown to generate solutions of the $A_{4}^{(1)}$ symmetric Painlevé equations from the seed solution invariant under dihedral group $D_{5}$. The other is the $k=3$ Bogoyavlensky lattice structure. It satisfies recurrence relations that naturally extend recurrence relations of the Volterra lattice. These results shed light on connection between Volterra--Bogoyavlensky lattices, dihedral symmetries, and rational solutions of higher Painlevé systems.

Dynamics of an impulse dielectric barrier discharge in pure ammonia gas using electrical characteristics and imaging analysis

A glow nanosecond discharge from a plane-to-plane impulse dielectric barrier discharge (iDBD) with ammonia gas has been characterised by employing fast imaging and electrical diagnostics. More precisely, the aim of this study is to investigate the dynamics of the discharge establishment under various conditions of applied voltage, pressure, and gas gap. The comparison between the current measurements and the image analysis exposes a strong correlation between the fast excitation and ionization wave velocity and the rising current velocity. This correlation has been found only for diffuse mode discharge since a front wave could be clearly defined, denoted as the luminous propagation front (LPF). Furthermore, this correlation is supported by a proportionality factor of 1.5 10$^{-3}$ which is systematic over the studied conditions. Further investigations are considered to evaluate the relevance of such a value over more parameters.

Surface dielectric barrier discharge - From O3 mode to NOx mode as a function of dielectric temperature

Surface dielectric barrier discharges (SDBDs) operating in atmospheric air are efficient sources of reactive oxygen and nitrogen species (RONS), making them promising candidates for food decontamination applications. However, their chemical output strongly depends on operating conditions and environmental humidity that can affect treatment efficacy and reproducibility. In this work, we characterize the transition between ozone-dominant (O3 mode) and nitrogen-oxidesdominant (NOX mode) operating regimes by combining ICCD imaging, optical emission spectroscopy, and time-resolved absorption measurements of O3 and NO2 . We demonstrate that an increase of the applied voltage and the dielectric temperature accelerates the shift from net ozone production to rapid O₃ destruction driven by NOx catalytic cycles, while water vapor further suppresses ozone formation through enhanced OH-and H-driven reactions. Spatiotemporal ICCD measurements reveal that humidity simultaneously modifies streamer morphology and enhances overall plasma intensity. These findings establish quantitative operating windows to control RONS production for applications requiring either oxidative (O3 -rich) or nitrosative (NOx -rich) biocidal environments, providing essential knowledge for optimizing plasma-based food safety technologies.

IS IT APPROPRIATE TO USE PATIENT EDUCATORS IN THE OSCE?

Introduction : As part of the reform of the second cycle of medical studies, a collaborative development process was implemented. Methods: This was initiated with patient partners, medical students and clinical tutors. The central idea is a consultation between students and patient partners within each OSCE rotation, followed by a systematic debriefing session, thereby making the OSCE rotations formative. Results: This initiative has been institutionalised since 2022 in a medical school as a compulsory formative assessment at the end of the general practice clinical rotation. Discussion: It enables a rethinking of the role of these OSCE within the learning process offered to postgraduate medical students by integrating a progressive approach specific to pedagogical processes into the competency-based approach. Conclusion: Both students and supervisors, doctors and patients alike, perceive the benefits, which invites reflection on possible adjustments to this reform of postgraduate medical education. This is what this article aims to shed light on.

Teaching medicine with patients as partners : A mapping of patient involvement in a family medicine residency program

Background: Across Canada and around the world, an increasing number of residency programs are seeking to involve patient partners in their academic curricula, yet few detailed examples exist at the postgraduate level.Objective: To describe an innovative initiative integrating patient partners into the Family Medicine Residency Program at the Université de Montréal (UdeM), grounded in the Montreal Model of patient partnership.Description: In this program, which welcomes approximately 350 residents, patients are involved at multiple levels: governance (Educational Council, new site development committee, resident orientation), assessment (admissions committee, competency evaluation committee, direct feedback), continuing education (communication workshops, participation in mental health clinical teams, quality improvement projects), and teaching activities (co-developed and co-facilitated courses). These initiatives are supported by structured supervision from the Office of Patient Partnership, ensuring methodological rigor and alignment with the primary care context.Results: This approach, recognized as exemplary by the joint CFPC/CMQ accreditation, offers a transferable model grounded in the principles of co-construction and the valuing of experiential knowledge.Conclusion: This description provides concrete examples and actionable insights for programs seeking to sustainably integrate patients into postgraduate curricula and to contribute to the democratization of knowledge in health care.

Etude des performances zootechniques et économiques des mini-fermes laitières dans le rayon de collecte de la Laiterie du Berger

L'objectif de cette étude est de déterminer les performances technico-économiques des petites exploitations laitières dans le rayon de collecte de la LDB à Richard-Toll et d'identifier les différentes races bovines présentes afin de fournir des informations sur les paramètres de reproduction et la gestion de l'exploitation. Ce travail s’est focalisé sur les mini-fermes de 2019 (25 mini-fermes), qui sont les plus anciennes et toutes en activité. Dans ces mini-fermes, 4 à 5 vaches sont mises en stabulation et, leur production est relevée quotidiennement. Une revue exhaustive des connaissances sur les fermes et l'analyse des enquêtes de terrain ont permis d'établir un état des lieux. Cette production atteint en moyenne 8 litres par vache et par jour au pic, avec des notes d'état corporel avoisinant 3 ± 1 lors des visites, un taux de gestation de 46,29 %, et un taux de gémellité quasiment nul avec respectivement 0,17 % en 2021 et 0 % en 2022. Les vaches de ces mini-fermes sont nourries et complémentées en aliments concentrés (Nèpes, un aliment spécial pour vaches laitières, et du tourteau).

Analysis of commercialization system of local guinea fowl (Numida meleagris) in the township of Lomé (Togo)

The purpose of this study is to analyze the marketing system of local guinea fowl in municipality of Lomé. A survey was conducted among 54 traders in 10 markets in the municipality. A total of three types of actors were identified in the local guinea-fowl marketing chain: The wholesalers, the urban resellers and the retailers. Analysis of the data reveals that the majority of traders are married people (93%) and aged of 41 ± 11 years. The activity is inherited from a parent (72%) and constitutes an essential source of income to meet basic needs. In addition, the study reveals a strong representation of retailers (68%) in the market made up of women, of Ewé ethnic group, 90% of whom originated from Maritime region. Our results showed that the savannah region is the main source of local guinea fowl for the municipality of Lomé in Togo. Wholesalers and urban retailers are the major players, earning profits of 358.33 F CFA and 357.48 F CFA per guinea fowl sold, respectively, which is significantly higher than that of retailers who only earn net unit surplus of 98.48 F CFA. Overall, the marketing of local guinea fowl in the municipality of Lomé is a profitable business and deserves to be supported in order to improve the distribution of income among stakeholders with a view to sustainable development. This support will be more effective if actions are developed to promote local guinea fowl and the marketing of its products.

Epistemologische Anforderungen der Zweiten Diskontinuität

Die Hochschulmathematik vermittelt ein stark verdichtetes Wissen, das sich auf mengentheoretische Definitionen und formale Beweise stützt und weitgehend von Kontextbezügen befreit ist. Dies ist die letzte Stufe einer langfristigen Entwicklung des mathematischen Denkens, die mit der physischen Wahrnehmung und dem Handeln in konkreten Situationen beginnt und in einem langen Prozess der Reformulierung und Verfeinerung wächst. Wenn ein junger Student/eine Studentin als Lehrkraft in die Schule zurückkehrt, muss er oder sie zu den Wurzeln zurückkehren und seine oder ihre Schülerinnen und Schüler in diesem Prozess begleiten und unterstützen. Diese Aufgabe ist mit vielfältigen erkenntnistheoretischen Anforderungen verbunden, auf die im folgenden Beitrag eingegangen wird.

Specificity of the knowledge in logic and its consequences on Klein's double discontinuity

In mathematics, logic is a field with a specific and transversal status. Indeed, it allows us to describe, control and validate mathematical activity. Therefore, it seems relevant to teach it in mathematics' classes.First, we present some research results from the DEMIPS’ « Logic and Proof » group. Based on interviews with university teachers, we will show different choices made for these kinds of courses and the different epistemologies relating to the proof that underlie them.Furthermore, since 2009, logic is faintly coming back in the french high school curriculum. Then, how can pre-service teachers rely on their university knowledges and transpose them to teach at high school level? We are going to answer this question of Klein's second discontinuity by presenting results from research in mathematics education about students’ difficulties and by explaining training situations we suggest.

In Georgia, Embracing the Ruptures: Between Geopolitical Shift, Mass Mobilisations, and Authoritarian Transition

This article, informed by the sociology of social movements, looks into the waves of mobilisations in Georgia between February 2022 and the summer of 2024, which preceded a phase of authoritarian consolidation of power. This pivotal period is characterised by an intensification of protests, which reveal the geopolitical tensions that exist within the country. The article draws on the theoretical framework of critical junctures to explore how these mobilisations materialise the rupture between the citizens’ aspirations and the government’s diplomatic shift. Furthermore, it examines the emergence of renewed protest practices, such as the symbolic use of Europe and Ukraine, and a general mistrust of traditional political elites. A focus on the dynamics of civil society prior to the enactment of the ‘foreign agents law’ enables a more detailed examination of the nuances of a resistance confronted with an impending institutional deadlock.

Breakdown and Continuities of Russian Imperialism in the Bessarabian Question after the Russian Revolution

This article examines the breakdown and continuities of Russian imperialism in the Bessarabian question following the 1917 Russian Revolution. It highlights the paradox of the officially anti-imperialist Soviet discourse, which combined the collapse of the old empire with the territorialization of a universalist ideology. The actions of the Communist International and the use of the principle of national self-determination allowed the USSR to transform its imperial project into an ideological model with universal ambitions. By analyzing the Bessarabian conflict and its diplomatic, ideological, and insurrectionary dimensions during the interwar period, culminating in the failure of the Tatar Bunar uprising in 1924, the article shows how the USSR attempted to project revolutionary expansion into the region. This study sheds light on the specificity of a renewed Soviet imperialism, concealed behind the rhetoric of national and social liberation.

When Words Tell Things: A Linguistic Archaeology of the Mother–Child Dyad

This paper tests the hypothesis that certain sound–meaning patterns associated with “mother” and “breast” may reflect a very ancient codiffusion, inherited from the earliest migrations of Homo sapiens and from the centrality of the mother–infant dyad. Within a framework of “linguistic archaeology,” four phonotactic traits are examined across 2,959 languages (“mother”) and 7,322 languages (“breast”) from the Lexibank and ASJP databases: [n]/[ŋ] and [na]/[ŋa] in initial position for “mother,” and [mu] and [amu] for “breast.” Their distribution is assessed through spatial analyses (Moran’s I, binomial z-scores on 2°×2° grids, random permutations, great-circle distances). The results reveal a non-random structuring for [n]/[ŋ] and [mu], with hotspots in Africa, South Asia, Island Southeast Asia, Melanesia, and Australia, regions that align with the southern routes of early Homo sapiens dispersal. The forms [na] and [amu], more geographically restricted, appear as regional archaisms. The strong geographic co-occurrence between [n]/[na] and [mu], contrasting with the limited spread of [amu], suggests an ancient lexical core linking “mother” and “breast,” not reducible to articulatory biases alone. Without positing a single protolanguage, the study shows that linguistic areology can reveal fossil traces of an early cultural structuring around the mother–infant dyad, providing partial support for the hypothesis of an initial cultural unity disseminated during the first out-of-Africa dispersals of Homo sapiens.

The contribution of social invariants to learning social work: an analysis of first-year students’ perceptions

This research examines the place and function of sociological knowledge in social work training, particularly through the teaching of social invariants proposed by Bernard Lahire (2023). These concepts, which can shed light on the fundamental structures of society, are studied here in terms of their reception and perceived usefulness by first-year students in the bachelor’s degree program in social work at Hénallux (Namur, Belgium). The study adopts a mixed approach: a questionnaire administered to 77 students, analyzed using descriptive statistics and correlation tests, is supplemented by eight interviews with students and two interviews with teachers, which are subjected to thematic analysis with a double coding cycle. The results highlight three major functions of invariants: (1) deciphering situations involving users, (2) a more complex understanding, and (3) capitalizing on solutions to address the vulnerabilities of the public. In addition, two specific advantages emerge from social invariants: their explanatory power as general concepts that can be used to elucidate social phenomena while promoting, through their contextual variation, a nuanced interpretation of situations encountered in social intervention, and the inter/transdisciplinary scope of invariants. While a minority of students remain skeptical of theoretical knowledge, the relational and pedagogical quality of teaching appears to be a decisive lever for appropriation. Despite some limitations mentioned, the study concludes that invariants are relevant as integrative tools, articulating sociological intelligibility, reflexivity, and professional intervention.

The Converse of the Real Orthogonal Holant Theorem

The Holant theorem is a powerful tool for studying the computational complexity of counting problems. Due to the great expressiveness of the Holant framework, a converse to the Holant theorem would itself be a very powerful counting indistinguishability theorem. The most general converse does not hold, but we prove the following, still highly general, version: if any two sets of real-valued signatures are Holant-indistinguishable, then they are equivalent up to an orthogonal transformation. This resolves a partially open conjecture of Xia (2010). Consequences of this theorem include the well-known result that homomorphism counts from all graphs determine a graph up to isomorphism, the classical sufficient condition for simultaneous orthogonal similarity of sets of real matrices, and a combinatorial characterization of simultaneously orthogonally decomposable (odeco) sets of symmetric tensors.

Succinct Oblivious Tensor Evaluation and Applications: Adaptively-Secure Laconic Function Evaluation and Trapdoor Hashing for All Circuits

We propose the notion of succinct oblivious tensor evaluation (OTE), where two parties compute an additive secret sharing of a tensor product of two vectors $\mathbf{x} \otimes \mathbf{y}$, exchanging two simultaneous messages. Crucially, the size of both messages and of the CRS is independent of the dimension of $\mathbf{x}$. We present a construction of OTE with optimal complexity from the standard learning with errors (LWE) problem. Then we show how this new technical tool enables a host of cryptographic primitives, all with security reducible to LWE, such as: * Adaptively secure laconic function evaluation for depth-$D$ functions $f:\{0, 1\}^m\rightarrow\{0, 1\}^\ell$ with communication $m+\ell+D\cdot \mathrm{poly}(λ)$. * A trapdoor hash function for all functions. * An (optimally) succinct homomorphic secret sharing for all functions. * A rate-$1/2$ laconic oblivious transfer for batch messages, which is best possible. In particular, we obtain the first laconic function evaluation scheme that is adaptively secure from the standard LWE assumption, improving upon Quach, Wee, and Wichs (FOCS 2018). As a key technical ingredient, we introduce a new notion of \emph{adaptive lattice encodings}, which may be of independent interest.
