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.

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.

Design of the IMAS interface data structure for flux-tube gyrokinetic simulations
A unified set of conventions and normalizations for the inputs and outputs of delta-f flux-tube gyrokinetic simulations has been developed within the ITER Integrated Modelling and Analysis Suite (IMAS). This new standard aims at facilitating benchmarks and data exchange between different code users, increasing the modularity of frameworks manipulating inputs and outputs from gyrokinetic simulations and serving as the basis for databases storing simulations from multiple gyrokinetic codes.

Supporting executable scientific workflows in a clustered Infrastructure: DARIAH-IT and H2IOSC
Workflows have become essential in digital humanities, enabling the formalisation, automation and reproducibility of complex research processes. As the humanities increasingly adopt data-driven methodologies, workflows offer structured approaches to manage diverse data and tools while supporting transparency and collaboration. Recognising this need, DARIAH-IT has advanced research infrastructure development by focusing on workflow-based services within the H2IOSC (Humanities and Cultural Heritage Italian Open Science Cloud) project. DARIAH-IT leads the design and implementation of a national cloud system to support digital humanities research, ensuring interoperability, FAIR data practices and semantic integration across disciplines. Central to DARIAH-IT’s effort within H2IOSC is AEON (dAriah sErvice Oriented iNfrastructure), a platform that enables the creation, execution and management of scientific workflows. AEON integrates service provisioning, semantic validation and runtime orchestration, supporting reproducible research and collaborative practices.
