Dynamically Heterogeneous Solvation Environment around a G-Quadruplex in Aqueous Solutions Containing Nucleobase Ionic Liquids

Abstract G-quadruplexes (GQs) are guanine-rich non-canonical nucleic acid structures that play crucial roles in different biological processes. Their structures and functions are highly dependent on the organization and dynamics of the surrounding solvent environment. Ionic liqui...

KRISHI.AI: an explainable machine learning framework for data-driven crop recommendation

Abstract Accurate crop selection is a fundamental determinant of farm productivity under varying soil characteristics and climatic conditions. Most current AI-based advisory systems are confined to predictive outputs or generic recommendations, providing little transparency into...

Prevalence of test anxiety among medical students: a systematic review and meta-analysis

Abstract Background Test anxiety is a situation-specific construct that can markedly impair cognitive functioning and academic performance in high-stakes educational environments. Medical students are frequently exposed to evaluative situations, and test anxiety is common in this...

Ethical and governance challenges in extracorporeal membrane oxygenation: a scoping review and practical framework for clinical and system-level decision-making

Abstract Background Extracorporeal membrane oxygenation (ECMO) is an advanced life-sustaining therapy used in selected patients with severe cardiac or respiratory failure. Its increasing use has raised complex ethical, clinical, organizational, and medico-legal challenges related...

Characterizations of twisted spacetimes

Twisted spacetimes generalize Robertson-Walker cosmological models by allowing the scale factor to depend on both spatial position and time, thereby modeling inhomogeneous cosmic expansion. This article establishes geometric conditions under which a Lorentzian manifold becomes a...

Pointwise Replicable Agnostic Learning: The Additive Term Is Unnecessary and the Fixed-Confidence Order Is Exact

Hopkins, Impagliazzo, and Ye (arXiv:2510.20200) introduced $\rho$-pointwise replicable learning and proved that every class of VC dimension $d$ admits a pointwise replicable agnostic $(\alpha,\beta)$-learner with $\widetilde O(d/(\rho^2\alpha^2)+1/(\rho^2\alpha^4))$ samples, aski...

First-Principles Investigation into Structural and Optoelectronic Properties of Mixed Halide Perovskites CsPbBr3– y X y (X = I, Cl, F; y = 0, 1, 2, 3) Using GGA, mBJ, mBJ + SOC, and HSE Functionals

Abstract This study presents a comprehensive density functional theory investigation into the structural, electronic, and optical properties of inorganic halide perovskites with the general formula CsPbBr3–yXy (where X = I, Cl, F; and y = 0, 1, 2, 3). Using the Vienna Ab initio S...

Exploring the exact soliton solutions and dynamical analysis to the model in fluid dynamics and plasma physics

This research studies the modified equal-width Burgers equation, an important model in both fluid dynamics and plasma physics. This model is commonly used to describe the traffic flow, optical pulses in fibers, ion-acoustic plasma waves, shallow water waves, etc. The new P/Q-expa...

Assessment of adult structural plasticity in Drosophila neurons

Unravelling how adult neurons reshape their architecture is key to understanding post-developmental plasticity. Drosophila clock neurons, which remodel their terminals on a daily basis, offer a unique model to examine the mechanisms underlying structural plasticity. In this study...

Cyber behaviour and personality nexus: clustering around security attitudes, FoMO, problematic social media use, and cognitive and personality traits?

Abstract Our research examines whether cyber behaviours can be classified through personality factors. The study involved 642 participants, including 314 from the United Kingdom (UK) and 328 from the Arab Gulf Cooperation Council (GCC). Using conscientiousness, neuroticism and ne...

Prognostic value of HALP score, Prognostic Nutritional Index (PNI), and Lymph Node Ratio (LNR) in right-sided colon adenocarcinoma: a retrospective single-center cohort analysis with clinico-pathological correlations

Abstract Introduction Preoperative systemic immunonutritional indices offer cost-effective, host-centric prognostic insights. This study evaluated the independent long-term prognostic utility of the Prognostic Nutritional Index (PNI), Hemoglobin–Albumin–Lymphocyte–Platelet (HALP)...

Dynamic salience as a basis for behavioural meta-malleability

Abstract Salience, the degree to which cues capture attention, is not fixed but updated through experience. Learning which cues anticipate meaningful outcomes requires cue–outcome relationships to be perceptible to begin with, rendering salience a gate for behavioural change. Bec...

A Case of Gastric Juvenile-Type Polyposis With SMAD4 Mutation

Juvenile polyposis syndrome (JPS) is a rare autosomal-dominant disorder characterized by the presence of multiple hamartomatous polyps in the gastrointestinal tract. JPS has been established to be attributable to SMAD4 mutations, which are frequently associated with severe gastri...

Association of rituximab with survival outcomes in primary testicular diffuse large B-cell lymphoma: a systematic review and meta-analysis of retrospective studies

Abstract Background Primary testicular diffuse large B-cell lymphoma (PT-DLBCL) is the most common subtype of primary testicular lymphoma (PTL). Standard treatment protocols generally encompass a multimodal approach, incorporating radical orchiectomy, rituximab-based chemotherapy...

Water Dissociation on Molybdenum and Tungsten Oxide Trimers: Roles of Oxidation State, Structure, and Microsolvation

Abstract Here we present results of a density functional theory based systematic investigation of water adsorption and dissociation on Mo3O9/Mo3O8 and W3O9/W3O8 clusters. For fully oxidized Mo3O9 and W3O9, adsorption of a single water molecule is strongly exothermic (−0.81 and −0...

The effect of intravenous remdesivir on endometrial receptivity in female mice

Objective: Pregnant women with coronavirus disease 2019 (COVID-19) are more likely than nonpregnant women to require admission to an intensive care unit, and many may require antiviral therapy. Remdesivir, an antiviral drug used to treat COVID-19, may exert toxic effects on speci...

Management practices and human–horse relationships are associated with horse personality traits

Abstract The human–horse relationship has evolved through centuries of domestication, shaping how horses are managed and interact with people. Horses show interindividual behavioural differences that constitute personality, with implications for welfare, management and human–hors...

Short-Term Efficacy of Tegoprazan Compared With Esomeprazole in Patients With Non-Erosive Reflux Disease and Nocturnal Heartburn Symptoms: A Double-Blind, Randomized Controlled Trial

Objectives: Tegoprazan is a novel potassium-competitive acid blocker that rapidly suppresses acid secretion. This study aimed to evaluate the efficacy of tegoprazan 50 mg compared with esomeprazole 20 mg in patients with non-erosive reflux disease and nocturnal heartburn symptoms...
