An Integrated Geospatial and Socio-economic Assessment of Flood Risk in North-western Nigeria Using Multi-Criteria Decision Analysis

Flood disasters have become increasingly frequent and severe in Nigeria, driven by a combination of climatic shifts and anthropogenic pressures. This research paper assesses flood risk vulnerability across the seven states of the Northwest geopolitical zone (Sokoto, Kebbi, Zamfar...

Q Quantum Theory III-B: Quantum Gravity -- Quantum and Ultraviolet Structure

Part III-A defines Q gravity through a single full $A=OP$ response field on a physical Minkowski reference spacetime. This companion develops its finite-order quantum structure as one Batalin--Vilkovisky (BV)/contact theory. In the minimal metric-coupled branch the local orientat...

Performance Optimization and Prospects of Double Network Hydrogels for Flexible Electronic Devices

Dual‐network (DN) hydrogels possess tunable polymer network architectures, exceptional mechanical robustness, and superior water retention capability. They demonstrate substantial potential in structural optimization and performance stabilization, thus garnering widespread attent...

Phloroglucinol derivatives from Dryopteris championii

Two previously undescribed phloroglucinol derivatives, drychamphloros A and B (1 and 2), were obtained from the whole plant of Dryopteris championii, together with seven known congeners (3–9). Their structures were determined via ECD (Electronic Circular Dichroism) calculations i...

What Works Against Populist Rhetoric? The Effects of Counter-Arguments on Democratic Attitudes

Abstract Politicians use populist rhetoric – arguments that portray politics as an enduring conflict between “the good people” and “the evil elites” – to generate support for attacks on constitutional safeguards, the media, and minorities. Yet, little is known about how to counte...

Early-warning surveillance of West Nile and Usutu viruses in wetland and larval habitat waters and in mosquito excreta using digital PCR

West Nile virus (WNV) and Usutu virus (USUV) are mainly avian mosquito-borne pathogens, increasingly cause human and equine disease in temperate regions. Mostly asymptomatic, current surveillance in France is reactive, based on clinical and veterinary reports, delaying signals fo...

Trends and Projections of Esophageal Cancer Incidence and Mortality in China, 1990 to 2050

Goals: The study aims to analyze and project esophageal cancer trends in China from 1990 to 2023 using GBD 2023 data. Background: Esophageal cancer (EC) remains a major public health challenge in China. Updated evidence on long-term trends and future burden is needed to inform pr...

Who cares for the caregivers? Health check-up participation among mothers caring for children with developmental disabilities in Korea: findings from the National Health Insurance Service database and a nationwide survey

Caregiving burden may hamper caregivers’ access to healthcare services. This study assessed participation rates of national health check-ups among mothers caring for children with developmental disabilities (MCCDD) in Korea and explored reasons for non-participation. We analyzed...

Perceptions and emergency medical service use for acute myocardial infarction among community-dwelling older adults: an embedded mixed method study

Acute myocardial infarction is a medical emergency where timely treatment is critical to improving survival. Older adults, however, delay seeking treatment and experience increased mortality because of misunderstandings and negative attitudes toward emergency medical services, es...

Comparison of the Sensitivity of Histopathological and Immunohistochemical Analyses With That of Serum Hormone Measurements for Early Detection of Antithyroid Effects in Rats Treated With Iodide Uptake Inhibitors

ABSTRACT Serum thyroxine (T4), triiodothyronine (T3), and thyroid‐stimulating hormone (TSH) measurements are widely used to detect antithyroid effects in rodent toxicity studies. However, the assays used to measure these hormones are costly and highly variable depending on the bl...

„V krvi důkaz, ztratíš průkaz!“ aneb k trestnému činu opilství v socialistickém Československu

The article focuses on the offence of drunkenness, understood as an endangerment offence, with particular emphasis on drink-driving. It combines a doctrinal legal analysis with an examination of criminal files from the District Court for Prague 1 and surveys the interpretation of...

Ὁ Πενταμετρικὸς Κύκλος: A Nested Palindrome Encoding the Pythagorean Consonances

We present the Pentametric Cycle (Ὁ Πενταμετρικὸς Κύκλος), a structure generated by an integer-valued quadratic formula 𝔓(n), the Pentametric Formula: 𝔓(n) = (n² + 4C(m))/5, with m = 4n² mod 10 and C(m) = (26m − 5m²)/24. We show that the correction term C(m), the Interval Map, co...

Ultrathin high-performance circular polarizers based on MoOCl2/NbOCl2 van der Waals heterostructures

Circularly polarized light (CPL) holds immense promise for diverse applications, including 3D displays, quantum information processing, biosensing, and optical imaging. However, high-performance, ultrathin, and easily integrable devices for CPL manipulation and discrimination rem...

Effect of generative artificial intelligence training on the competencies of border guard agents.

This study assessed whether a generative artificial intelligence training model develops the professional competencies of border guard agents in training more than traditional instruction. A quasi-experimental pretest and posttest design was applied to 168 agents at a training sc...

Machine learning-based performance prediction and intelligent screening of compound collector for low-rank coal with varying slime contents

The traditional trial-and-error development of compound collectors for low-rank coal (LRC) flotation is inefficient, and the process is susceptible to slime interference. To address this, a data-driven machine learning (ML) strategy was proposed to predict and screen optimal coll...
