Prevalence and correlates of suicidal behavior among adults with chronic health conditions in Malawi
Over 70% of completed suicides occur in low- and middle-income countries. However, limited information is available on suicidal behavior encompassing ideation, plans, and attempts among high-risk populations in these settings. We investigated the prevalence and correlates of suic...

Gastric serum biomarkers are established for gastric cancer risk assessment, but their utility for extra-gastric malignancies and long-term risk stratification remains unexplored. We prospectively evaluated serum pepsinogens (PGI, PGII), gastrin-17 (G-17) and anti- H. pylori IgG...

Abstract The effect of prenatal organophosphate esters (OPEs) exposure on offspring reproductive development and the potential role of the placenta remain unclear. We investigated the associations of prenatal OPE exposure with the second-to-fourth digit ratio (2D:4D) and the medi...

Abstract Background Upper-limb impairment after stroke can restrict hand use, activities of daily living, and functional independence. Mirror therapy (MT) and soft robotic glove (SRG)-based rehabilitation represent technology-enabled approaches to upper-limb rehabilitation. The e...

Predicting insulin resistance in non-diabetics
This cross-sectional study aimed to compare obesity indicators for predicting insulin resistance using machine learning. Data were obtained from NHANES 2015 to 2018, focusing on a nondiabetic adult population. Insulin resistance was defined as HOMA-IR ≥ 75th percentile of the tra...

Oral submucous fibrosis (OSF) is a chronic, progressive, and potentially malignant disorder characterized by severe oral cavity remodeling. The condition is driven by a painful burning sensation and a pathognomonic restriction of mouth opening (trismus), severely diminishing pati...

Graduate unemployment, financial strain, and social marginalization in Pakistan: a qualitative study
Purpose This study explores how unemployment shapes the lived experiences of university graduates in the province of Khyber Pakhtunkhwa (KP), Pakistan, with particular attention to its effects on social status, decision-making agency, life-course transitions, and family dynamics....

Time-series forecasting is a foundational task in data science, yet reported improvements over naive baselines are frequently small, dataset-dependent, and rarely subjected to formal significance testing. We present a reproducible benchmark comparing three families of forecasting...

BACKGROUND: Leadless cardiac resynchronization combining WiSE system ultrasound-mediated left ventricular pacing with leadless right ventricular pacing has been reported. However, atrioventricular-sequential left ventricular pacing triggered by atrial leadless pacing impulse with...

ABSTRACT Concrete, inherently porous and prone to microcracking, is susceptible to the ingress and diffusion of aggressive external agents. Traditional protective coatings are often constrained by inadequate interfacial adhesion and suboptimal barrier performance, rendering them...

Four pre-registered attempts to learn second-order modulation in a minimal plasticity testbed found nothing, and the learners failed their own positive controls. Before improving the learners further, this note measures whether anything was there to find, by comparing hand-built...

AmpliconSuite: an end-to-end workflow for analyzing focal amplifications in cancer genomes
Abstract Here we present AmpliconSuite, a toolkit for focal amplification analysis from cancer whole-genome sequencing that identifies extrachromosomal DNA (ecDNA), breakage–fusion–bridges and other amplification modes. Its ecContext module categorizes ecDNA structures to underst...

We extend the E8 harmonic lattice framework by decomposing the 240 root vectors into two orthogonal subspaces of dimensions 128 and 112, corresponding to the 2^7-torsion and (2,2,2,2)-isogeny subdomains respectively. This decomposition generates a natural projection onto elliptic...

Abstract Linguistic racism, understood as a form of “new racism”, continues to marginalise TESOL teachers’. While its traumatic effects are acknowledged, little is known about how teachers experience and heal from such trauma. This study seeks to understand how three linguistical...

This study aimed to evaluate the impact of ultrasound-assisted extraction (UAE) on the chemical composition and biological activities of gabiroba waste oil (GWO), compared to conventional Soxhlet extraction (SE). GWO was characterized for carotenoid content and analyzed by GC-MS...

While the electroweak Brout–Englert–Higgs mechanism accounts for merely 1–2% of the mass of visible baryonic matter via current-quark Yukawa couplings (2m_u + m_d ≈ 9.0 MeV ≪ M_p = 938.272 MeV), the remaining 98–99% originates dynamically from the non-abelian scale anomaly of the...

Paneitz Resonances and Index Growth on a Sphere Times a Hyperbolic Surface
For a fixed closed connected hyperbolic surface (Sigma,h) of curvature -1, we determine the full Paneitz spectrum for g_t = g_S2 plus t^(-1)h, where the round sphere has curvature 1 and t>0. The exceptional scales with nonconstant kernel form a locally finite set, with explicit r...

Given the increasing prevalence of diabetes mellitus (DM), understanding its impact on anterior cruciate ligament reconstruction (ACLR) revision risk is important for clinical decision-making and patient counselling. This study evaluated whether DM is associated with an increased...

Groundwater-recharge planning in semi-arid hard-rock aquifers is uncertain when site selection relies only on surface indicators. This study integrates geographic information system (GIS) analysis, vertical electrical sounding (VES), and Dar-Zarrouk parameters to screen candidate...
