J-PAS: Semisupervised Sim-to-Obs Transfer for Robust Star–Galaxy–Quasar Classification

Abstract Modern astrophysics and cosmology increasingly rely on simulations and cross-survey analyses, yet differences in instrumentation, calibration, and modeling introduce distribution mismatches between simulated and observed datasets (domain shift). This occurs when the join...

Learning behaviour is consistent across time and tasks in Formica fusca ants

Abstract Research on interindividual behavioural and cognitive variability has gained momentum over the last few decades. Most studies focused on vertebrates, revealing that individual cognitive performance can be stable across time and tasks and linked to other behavioural trait...

Organizational Monsters and the Shaping of Systemic Irresponsibility

Abstract Organizational monsters populate capitalist societies and shape the conditions of systemic irresponsibility. Building on organizational sociology and critical approaches, I argue that organizational monsters are powerful yet ambiguously organized and unevenly recognized...

Timing of PCI in Patients Undergoing Transcatheter Aortic-Valve Implantation

BackgroundApproximately one half of patients undergoing transcatheter aortic-valve implantation (TAVI) have concomitant coronary artery disease. Although percutaneous coronary intervention (PCI) is often performed before TAVI, the preferred treatment strategy has not been establi...

Multiple orthoflaviviruses secrete sfRNA in mosquito saliva to promote transmission by inhibiting MDA5-mediated early interferon response

Abstract Numerous orthoflaviviruses transmitted through the bites of different mosquito species infect more than 500 million people annually. Skin infection at the bite site represents a critical and conserved step in transmission and a deeper understanding of this process will p...

Cancer in systemic sclerosis: clinical associations and prognostic impact from the EUSTAR registry

BACKGROUND: Cancer represents a major cause of mortality in systemic sclerosis (SSc). Established risk factors are limited to specific subsets, particularly early diffuse anti-RNA polymerase III (POLR3)-positive disease, needing further exploration. METHODS: We performed a nested...

Cyberknife radiosurgery for hemifacial spasm

Background: Surgical management of hemifacial spasm (HFS) may be contraindicated in medically unfit patients or declined because of the potential risks associated with surgery. Therefore, minimally invasive and non-invasive alternatives merit investigation. This preliminary study...

Shoulder MRI for Forensic Age Estimation: Ossification Staging of the Proximal Humeral Epiphysis

Background/Objectives: Magnetic resonance imaging (MRI) of the proximal humeral epiphysis offers a radiation-free alternative for forensic age estimation in living individuals. This study aimed to characterize the relationship between chronological age and epiphyseal maturation u...

Ultraslow brain dynamics as neurophysiological markers of information sampling during learning

To learn, we must actively sample information from our environment: selecting, prioritizing, and extracting relevant cues. Here, we investigated whether ultraslow event-related potentials (ERPs) could track information sampling as participants learned new words from sentence cont...

Biomarkers in facioscapulohumeral muscular dystrophy

PURPOSE OF REVIEW: Facioscapulohumeral muscular dystrophy is one of the most frequent myopathies. Its clinical presentation and genetic background are unique. FSHD needs reliable and measurable biomarkers to monitor the disease and assess the efficacy of therapeutic approaches. T...

Entropy maximization and weak Gibbsianity of quasi-free fermionic states

Abstract In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invariant states with a fixed two-point function and suggested that the maximizer is unique. In s...

Magnetic Field Tuning of Modulated Magnetic Orders in CrOCl at the Two‐Dimensional Limit

Chromium oxychloride is a van der Waals magnet with intrinsic competing exchange interactions, including a strong antiferromagnetic one, source of a very rich magnetic phase diagram, with ferrimagnetic, antiferromagnetic, and canted states, up to high magnetic fields. We investig...

Scaffold, Not Seed -- Except One: Positional Encoding and the Emergent Group Representations of Grokking Transformers

A small transformer that groks modular addition famously discovers the Fourier representation of Z/p on its own. Prior work asks what algorithm is learned and which irreducible representations are used, always with the architecture held fixed. We ask one level up the causal chain...

Transposed-letter effects as a function of the location of transpositions

We examined how Transposed-Letter effects (TL effects: e.g., ASBENT, derived from ABSENT, compared to the substituted-letter [SL] control ALPENT) might vary as a function of the location of the TL effects relative to fixation. The positions of the TL and the initial fixation loca...

Detection of spiking motifs of arbitrary length in neural activity using bounded synaptic delays

In the context of spiking neural networks, the temporal coding hypothesis is increasingly preferred over the rate coding hypothesis due to its advantages in processing speed and energy efficiency. In temporal coding, synaptic delays are crucial for processing signals with precise...

What does a territory tell? Co-constructing heritage through complex social values in inner contexts

Italian inner areas are increasingly affected by depopulation, demographic ageing, and territorial fragmentation. In these contexts, cultural heritage is frequently mobilised as a resource for local development and regeneration. While heritage studies have widely recognised that...

Quality of life assessment in individuals with schizophrenia: a COSMIN-based systematic review of S-QoL41 and S-QoL18 incorporating neurobiological support

Background Quality of life is a key outcome in schizophrenia, requiring valid patient-reported outcome measures. We evaluated Schizophrenia Quality of Life (S-QoL) instruments. Methods We searched PubMed, PsycINFO, and Web of Science from inception to Dec 10, 2025. Measurement pr...

Widespread thermophilization but weak link to climate warming in Europe’s summit plant communities

Abstract Recent changes in alpine vegetation are often attributed to climate warming, particularly community composition shifts towards more warmth-associated species, or thermophilization. Here we assess the link between thermophilization and warming across 53 European mountain...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ 56 Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Gu...
