Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dar...

Characteristic cycle and wild Lefschetz theorems

Abstract By relying on a new approach to Lefschetz type questions based on Beilinson’s singular support and Saito’s characteristic cycle, we prove an instance of the wild Lefschetz theorem envisioned by Deligne. Our main tool are new finiteness results for the characteristic cycl...

Overcoming Sampling Limitations Using Machine-Learned Interatomic Potentials: The Case of Water-in-Salt Electrolytes

Abstract Machine-learned interatomic potentials hold the promise to enable the modeling of highly concentrated liquids over meaningful time scales, far from reach for current ab initio electronic structure methods. Here we evaluate the performances of various MACE potentials in m...

Long Fluorescence Lifetime Molecular Rotors Based on the 4,4‐Dicyano‐BODIPY Core

Environmentally sensitive fluorescent probes with extended emission lifetimes are highly valuable for fluorescence lifetime imaging microscopy (FLIM) in live cells, as they enable superior temporal separation of the probe's signal from background autofluorescence. Here, we demons...

Time-varying formation control via output feedback for multi-agent systems over switching networks with hidden Markov dynamics

This paper addresses time-varying formation control for a class of multi-agent systems. In particular, distributed static output control laws are designed for homogeneous discrete-time linear multi-agent systems whose network topologies switch according to an unknown Markov chain...

School principals' burnout trajectories: Nature, predictors, and outcomes

This study seeks to achieve a dynamic person-centered understanding of the distinct burnout trajectories observed among 1574 Finnish school principals measured five times over a period of four years. Our results revealed that burnout trajectories corresponded to five main profile...

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

ABSTRACT We describe the synthesis of a family of photoemissive linear Cu(I) complexes bearing mesoionic carbenes (MIC) and amido ligands of the general formula Cu(MIC)NR 2 (NR 2 = carbazolide, diphenylamide). Careful tuning of the electronic and structural properties of both lig...

Enhancement of mechanical performance in metakaolin-based geopolymer by cyclic loading and creep process in relation with microstructural evolution

Geopolymers are more and more widely used in engineering applications as low carbon construction materials. Their mechanical properties under monotonic loading have been widely investigated. However, there is still a crucial need to investigate their mechanical responses under cy...

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

ABSTRACT Control of light emission underpins photonics and radiation detection. Strong coupling between excitons and confined electromagnetic modes forms light–matter states known as polaritons, enabling emission control. In scintillators, such effects have been investigated main...

The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP7

Cloud processes constitute one of the key uncertainties for climate change projections. The fourth iteration of the Cloud Feedback Model Intercomparison Project, CFMIP4, contributes to the Coupled Model Intercomparison Project phase 7 (CMIP7), by providing a set of global climate...

Not speaking my language: playback experiments reveal early-orphaned human-reared adult cheetahs lack interest in species-specific vocalizations

Abstract Early adult models, particularly the mother, play an essential role in tuning perception to build the multimodal representation of species-specific social signals, especially in mammals. Therefore, early maternal loss adversely impacts social integration in mammals. More...

Interpretable machine learning for automatic rock mass classification in TBM tunneling: a case study of Beishan URL

Abstract Accurate rock mass classification is essential for safe tunnel boring machine (TBM) excavation, yet raw TBM monitoring data are often affected by shutdowns, machine adjustments, and transient disturbances, weakening their correlation with geological conditions. This stud...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presenc...

Reservoir Neuromorphic Computing Based on Spin-Orbit Coupling in an Organic Crystal Resonator

Abstract Neuromorphic computing is at the basis of the recent progress in artificial intelligence, but this progress is accompanied by an increasing demand for computational resources and power supply. Reservoir neuromorphic computing uses a nonlinear physical system to replace a...

Probabilistic inference of homonymous and heteronymous recurrent inhibition in human muscles from large-scale motor neuron recordings

Understanding how spinal circuits shape motor neuron behavior during muscle contractions remains a major challenge. Here, we combined large-scale motor unit recordings with simulation-based inference to generate probabilistic estimates of homonymous and heteronymous recurrent inh...

Core open science practices in major medical journals: development of an automatized tool based on a Large Language Model

Background Open science practices are increasingly promoted to improve the transparency and reproducibility of biomedical research, and their large-scale monitoring has been identified as a priority by initiatives such as the UNESCO Recommendation on Open Science. Existing automa...

Sex Differences in Prefrontal Oxygenation and Neuromuscular Fatigue to Incremental Cycling and Cognitive Testing Lead to Similar Cognitive Performance

Purpose: Cognitive-motor dual-task performance is prevalent in many sports and appears to be impaired during high-intensity exercise, in association with central fatigue and cerebral deoxygenation. However, the extent to which these responses differ between males and females rema...

Over 400 V Field‐Plate Enhanced Vertical Diamond Schottky Diodes With Near‐Ideal Behavior and Over 2700 A/cm 2 Current Density

Vertical diamond Schottky barrier diodes with field‐plate edge termination were fabricated on 1.5 μm low‐doped () epilayers grown on heavily boron‐doped substrates. Devices with Schottky radii of 25–350 μm and FP lengths of 0–20 μm were systematically characterized. Temperature‐d...

Workflow management systems and reproducible pipelines for Plasmodium falciparum genomic surveillance: tools, design principles and infrastructure challenges

Genomic data are increasingly leveraged to enable malaria genomic surveillance, with many teams now generating Plasmodium falciparum sequence data for routine analysis. However, downstream analysis remains dependent on ad-hoc scripts and local infrastructure. This reliance limits...

Semiclassical tunneling for some 1D Schrödinger operators with complex-valued potentials

We consider the non-selfadjoint, semiclassical Schrödinger operator \mathscr{L}(h) := -h^{2}\partial_{x}^{2}+e^{i\alpha}V , where \alpha \in (-\pi,\pi) and V\colon \R\to \R_{+} is even and vanishes at exactly two (symmetric) non-degenerate minima. We establish a semiclassical tun...
