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.

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.

Digital Reconstruction of a Feminist Literary Past: Topic Modelling Elisa Mújica's Newspaper Criticism (1972–1974)
Elisa Mújica (1918–2003) is increasingly recognised as one of the most important Colombian women writers of the twentieth century. Yet her work as a critic in the Lecturas Dominicales supplement in the newspaper El Tiempo – a central venue in the Colombian literary field – remains under-studied. This article presents a mixed-methods analysis of Mújica's columns from 1972 to 1974, combining topic modelling with close reading under the framework of data feminism. Using latent Dirichlet allocation implemented in R on a corpus of 572 document segments derived from digitised columns, I model six topics. Rather than treating these topics as purely formal clusters, I read them as traces of gendered practices in a literary field still dominated by male authors and authorities. Guided by data feminism (D'Ignazio and Klein 2020), I argue that topic modelling can help make visible the asymmetrical distribution of gendered authority in the archive, while close reading reveals how Mújica simultaneously participates in and questions masculinised canons. The article demonstrates how computational methods and feminist theory can jointly illuminate the politics of literary value in twentieth-century Latin America.Published version, formatted by the journal.

The Wikibase Ecosystem in DH and GLAM
DARIAH-EU Working Group DHwiki presents this White Paper about Wikibase and the Wikibase Ecosystem as a digest of its permanent activity in providing documentation about MediaWiki-based software solutions to researchers. The output of the Working group is accessible on its Wikibase instance at https://dhwiki.wikibase.cloud. As diverse as the Working Group itself is the target group of this report: DH researchers, GLAM institutions, contributors to the software platforms provided by Wikimedia, and software developers. When starting to engage with Wikidata and Wikibase, we have seen ourselves sometimes lost in a diverse landscape of disperse documentation resources with different scope and aimed at differently skilled readers. With this contribution, we hope to provide a comfortable pathway towards adopting Wikibase in FAIR Linked Data publishing and collaborative data curation workflows.To help users navigate these platforms, this article brings together the main elements of the Wikibase ecosystem with a specific focus on DH and GLAM usecases. It explains the main structure and features of Wikibase, discusses key processes such as data round-tripping and reconciliation, and examines the role of Wikidata and Wikibase in managing identifiers, authority data and controlled vocabularies. By bringing these aspects together, the paper aims to supportthe use of Wikibase in FAIR-compliant and collaborative data workflows, while also drawing attention to wider issues such as sustainability, governance andreuse.
