Bang-Time Perturbations and Redshift Drift in LTB Cosmology: Regularity, Distance Compensation, and Light-Cone Response

We study how radial variations in the bang time affect redshift drift in Lemaître–Tolman–Bondi cosmologies. Starting from the neighboring-light-cone equations, we derive a linear response system and evaluate it for regular dust and Λ-bearing model families. In the sampled parabol...

Machine-Checked Simplicial Chain Complexes over F_2 and Metric Filtration Invariants for Relational Resolution Theory in Lean 4

We present a self-contained, machine-checked formalization in the Lean 4 theorem prover (Mathlib4) of the core algebraic-topological invariants underlying discrete metric filtrations in Relational Resolution Theory (TRR 3.0). Specifically, we formalize: (1) the monotonicity and d...

Multimodal Single-Particle Characterization of Airborne Microplastics Reveals Physicochemical Heterogeneity and Aging-Related Features

Abstract Airborne microplastics (AMPs) have emerged as an important atmospheric contaminant; however, their physicochemical characteristics at the individual particle level remain poorly understood. In this study, a multimodal single-particle analytical approach integrating fluor...

Beyond Temporary: Exploring Marketing Strategies for Pop-Up Shops and Temporary Retail Spaces

The rapid growth of e-commerce and changing consumer preferences have encouraged brands to adopt pop-up shops and temporary retail spaces as flexible tools for product launches, brand promotion, and market testing. Although interest in temporary retail continues to grow, research...

Defect‐Anchored Pt–Ov–Ti Charge Bridges Enable Iodine‐Mediated Selective Photocatalytic Gold Recovery From Electronic Waste

ABSTRACT Gold is indispensable to modern technologies, yet its supply remains heavily dependent on environmentally intensive primary mining. Rapidly accumulating electronic waste (e‐waste) represents a valuable urban mine, but Au recovery is still constrained by corrosive lixivia...

What Should We Write on End of Rotation Evaluations? A Mixed-methods Exploration of General Surgery Resident and Faculty Perspectives

BACKGROUND: Narrative comments on resident end-of-rotation (EOR) evaluations are essential to competency-based assessment in surgical training, yet residents often perceive them as poor quality and variably useful. We explored resident and faculty perspectives on satisfaction wit...

Implementing the EU Deforestation Regulation with an equity perspective and its potential regulatory impacts on forests and livelihoods

The EU Deforestation Regulation (EUDR) seeks to ban commodities associated with deforestation from the EU market. Even though uncertainty about regulatory enforcement and its impacts persists, governments, companies and civil society in origin countries of cocoa, coffee and other...

Attracting oscillations in sequential distributive multisite phosphorylation

The sequential distributive n-site phosphorylation cycle with one kinase and one phosphatase admits attracting positive periodic orbits under mass-action kinetics for every n≥3. An explicit three-site family has a fixed positive equilibrium, a transversal imaginary-eigenvalue cro...

The Black Hole Bifurcation Paradigm in Finsler-Mucini TR Gravity: Geometric Evaporation, Coherent Fusion, and Singularity Resolution during Cosmic Retraction

Résumé : Cet article formalise le rôle dynamique et l’évolution structurelle des horizons locaux des trous noirs dans le cadre de la gravité thermo-relativiste (TR) de Finsler-Maxwell. En opérant dans le fibré tangent à 8 dimensions \(TM\) de la géométrie de Finsler, nous examino...

Damage-specific evolution of a fluorine-free PDMS/TPU–ZnO coating on nylon/spandex fabric: Differential responses of Si-containing surface species and ZnO-rich surface features

Fluorine-free textile coatings require durable surface chemistry and particle-derived architecture, yet their damage-specific evolution is poorly resolved by static contact angles alone. Polydimethylsiloxane, thermoplastic polyurethane and silane-treated zinc oxide were deposited...

Emergency clinicians’ knowledge and perceptions of training, education, and resources in eating disorders

Abstract Background Emergency clinicians have an important role in the recognition, assessment, and emergency management of patients with eating disorders. International studies suggest emergency clinicians receive limited training in eating disorders; however, Irish data are lac...

Assessment of Cognitive Engagement in Virtual Reality Using Near-Infrared Spectroscopy (fNIRS)

This pilot study investigated prefrontal cortex (PFC) activation during a mental arithmetic task in a virtual reality (VR) environment, using functional near-infrared spectroscopy (fNIRS) to assess cognitive engagement. Seven university students completed a relaxation phase follo...

Critical Lorentz Bounds for Hankel Multipliers with Slow Phases

For compactly supported radial symbols with a logarithmic slow phase near a sphere, we characterize the bounds L^{p,q}_rad → L^{p,r}_rad at p = 2d/(d + 1) and p = 2d/(d − 1) for every 0 < q,r ≤ ∞. We assume Φ is C², a = Φ′ > 0, a(v) → 0, and |a′(v)| ≲ a(v)/v; neither monotonicity...

Low-Dose Glucocorticoids Adjunctive to Flow Diverter Therapy for Unruptured Intracranial Aneurysms Improve Cerebrovascular Outcomes

Abstract Flow diverter (FD) implantation is standard for unruptured intracranial aneurysms (UIAs), but cerebrovascular complications persist. This nested study within a prospective multicenter cohort evaluates whether short-term, low-dose glucocorticoid use is associated with cer...

Understanding the experience of school leaders working part-time

In Australia, although part-time employment is widespread across the teaching workforce (27%), part-time leadership remains relatively uncommon. Currently, 8% of middle leaders and 4% of senior leaders hold part-time roles. Perhaps due to this scarcity, very little research has e...

Fabrication of Polyurea-Based Ionogels for Strain Sensing with High Conductivity, Flame Retardancy, and Room-Temperature Self-Healing

Abstract Flexible sensors used under high temperatures and open flames are in high demand in fire rescue and similar scenarios, yet related research remains limited. An intrinsic flame-retardant polyurea-based ionogel with high ionic conductivity and room-temperature self-healing...

NeuroMetBench: patient-aware evidence bounds for transcript-derived metabolic representations across cancer proteogenomic contexts

Transcript-derived metabolic representations connect gene expression with pathway state, but interpretation depends on sampling unit, endpoint, cohort, and validation evidence. NeuroMetBench is a patient-aware methodology that keeps target quantity, independent unit, endpoint map...
