Hypoxia-inducible factor 2α does not regulate cortical brain development

Dynamic changes in physiological oxygen levels are crucial for proper cortical brain development. In this context, oxygen is important not only for its role in energy metabolism but also as a signaling molecule. While much is already known about its most prominent signaling facto...

The Xenoreactome: Where Foreign Chemistry Becomes Biological Organization

Abstract Biological systems can perform chemistry beyond their evolved reaction networks, but a reaction that is chemically possible does not necessarily occur in an intact system. I define the xenoreactome as the state- and reference-dependent network through which foreign chemi...

Between the Lines: Decoding Signaling Differences in Public and Private Sector Job Advertisements

ABSTRACT To compete in the “war for talent,” public sector employers must demonstrate advantages over private employers. While public service motivation (PSM) predicts sector preference, scholars disagree on whether public employers (can) effectively signal PSM in job advertiseme...

Weaker Coherence, Weaker Reciprocity: Comparing the Semantic and Social Organization of Moltbook and Reddit

Large language models enable the creation of autonomous agents that interact in social environments, raising the question of whether agent-based platforms reproduce the organizational properties of human social networks. We compare Moltbook, a social network populated by AI agent...

Ligand-Dependent Affinity but State-Dominated Efficacy in Structure-Based GPCR Pharmacology Prediction

Abstract High accuracy in structure-based prediction of G protein-coupled receptor (GPCR) efficacy may reflect the receptor state rather than ligand-specific information. We addressed these information sources using state rules, ligand-blind baselines, matched receptor-state cont...

Density-selected topological pathways in the melting of single-particle-thick stripes

The melting of stripe-forming systems involves changes in connectivity that are not fully captured by conventional structural and orientational descriptors. We investigate a two-dimensional model with competing interactions whose low-temperature phase consists of one-particle-thi...

A CONCEPTUAL "QUICK FOODY" MULTI-SIDED BUSINESS MODEL: NURTURE B40-PRENEURS AND ENHANCE JOB OPPORTUNITIES IN AFFORDABLE BREAKFAST BUSINESS

This paper presents the "Quick Foody" conceptual business model, an innovative digital platform designed to address the distinct needs of various customer segments like breakfast consumers, breakfast food providers, and donors, with a specific focus on the B40 community and food-...

Comparative Two-Year Outcomes of Three Different Three-Piece Intraocular Lenses in Flanged Intrascleral Fixation

Background and Objectives: To compare 2-year positional stability, endothelial preservation, and visual outcomes of three three-piece intraocular lenses (IOLs) implanted by the Yamane technique: Eyecryl (polypropylene haptics, 5° haptic angulation), Sensar OptiBlue AR40e (polymet...

Extracting the pairing gap from van Hove singularities in RF spectra of the Fermi Hubbard model

We show that van Hove singularities in rf spectra of the 3D attractive Fermi Hubbard model provide a robust route to extracting the pairing gap. Four types of singularities are classified, and their spectral positions are shown to depend solely on the pairing gap $Δ$ and chemical...

Comparing SGLD and a fixed-noise predictor-corrector adaptation in canonical joint energy-based models on CIFAR-10

Abstract Joint Energy-Based Models (JEM) unify classification and generation within a single network and support out-of-distribution (OOD) detection. Canonical JEM training relies on stochastic gradient Langevin dynamics (SGLD); a theoretically motivated alternative, the Predicto...

Ets2 Is an Activity‐Dependent Transcriptional Regulator of a Fast‐Twitch Muscle Program

The functional properties of excitable cells, including skeletal muscle, are regulated by electrical activity. Distinct motoneuron firing patterns control contraction speed, strength, and endurance of fast- and slow-twitch myofibers by activating transcriptional programs that spe...

Nomophobia in the association between sport anxiety and happiness: Evidence from a cross-sectional mediation model

This study examines the relationship between sport anxiety and happiness by focusing on the mediating role of nomophobia among university students. Grounded in the Transactional Model of Stress and Coping and Uses and Gratifications Theory, the study uses these theoretical perspe...

Molecular Beam Epitaxy Synthesis of Ternary Nitride PrTaN2 and its Crystal Structure Determination

Abstract We report the discovery of a novel ternary nitride PrTaN2 synthesized as a thin film using molecular beam epitaxy. The combination of e-beam evaporation for refractory elements and a radio-frequency nitrogen radical source enables growth under a highly nitriding environm...

Breathing chimera states from purely triadic interactions

Chimera states, characterized by the coexistence of synchronized and desynchronized dynamics in identical oscillators, are typically studied in systems with pairwise interactions. Recent studies have shown that purely higher-order interactions can support chimera states. Here, we...

Boundary-driven anisotropic coarsening in conserved phase separation

Universal scaling in phase separation is typically assumed to be isotropic in systems with conserved dynamics. Here we show that boundary forcing alone can break this dynamical scaling symmetry, leading to anisotropic coarsening, with different effective global growth laws observ...

Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM

Abstract Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic and spatially varying contributions are difficult to disentangle with a single technique. Here we pr...

An Open Multi-Campus Dataset of Academic Service Requests Before and After Administrative Process Redesign

This paper presents an open, anonymized dataset of academic service requests collected before and after an administrative process redesign in a multi-campus university in Ecuador. The dataset was extracted from the Sistema Nacional Académico and covers two consecutive six-month p...

Addressing disordered eating in post-primary schools in Northern Ireland: a mixed-methods study of pupil and caregiver perspectives

The prevalence of eating disorders (ED) among children and young people is becoming an increasing issue worldwide. Also of concern is the prevalence of disordered eating (DE), with an estimated 1 in 6 children in Northern Ireland engaging in disordered eating behaviours, which is...

A Journey Through ICPIG History: From Its Origins to the 36th Edition

The International Conference on Phenomena in Ionized Gases (ICPIG) is one of the longestrunning and most influential international conferences in plasma physics. Founded in Oxford in 1953 by Hans von Engel and Gordon Francis, ICPIG has played a central role in fostering scientifi...

"Everyone remembers their first day at school". Exploring the use of phased starts as a primary school transition practice for pupils in Northern Ireland.

Transition to formal schooling is a significant milestone in children’s lives. Effective management of this is important as successful transitions are a stable predictor of later school success (Rimm-Kaufmann & Pianta, 2000). Northern Ireland (NI) has one of the lowest compulsory...
