Impact of high temperatures on healthcare utilisation among older adults: a scoping review

Abstract Background Rapid global ageing coincides with rising temperatures and increasing strain on healthcare services. High temperatures are associated with increased healthcare demand, yet evidence on older people’s healthcare utilisation remains fragmented and is often servic...

Diffusion-Based Nanostructure and Self-Healing Characterization of Asphalt Binders Using Molecular Dynamics Simulations

Abstract Conventional macroscale and microscale experiments have not fully elucidated the thermodynamical behaviors of asphalt binders’ self-healing, particularly under varying thermal conditions and fracture dimensions, limiting understanding of nanoscale molecular processes. Th...

Pepsinogen Assay Findings in Individuals With Gastric Atrophy and Intestinal Metaplasia

Serum pepsinogen (PG) testing is widely used as a non-invasive biomarker for gastric atrophy; however, its clinical interpretation varies depending on the severity and distribution of gastritis as well as on the assay methods. Autoimmune gastritis is characterized by markedly dec...

Rehabilitation of Bukharan markhor Capra falconeri heptneri Zalkin, 1945 numbers in Uzbekistan

During the first half of the twentieth century, Bukharan markhor (Capra falconeri heptneri Zalkin, 1945) experienced a pronounced population decline in Uzbekistan, creating an urgent need for the establishment of specially protected areas to conserve and restore the species. Curr...

Axisymmetric p-harmonic modes in circular cones: nodal classification and two-term asymptotics

We study homogeneous axisymmetric solutions of the p-Laplace equation in a circular cone with zero lateral boundary values. A lifted phase gives one positive and one negative homogeneity exponent for each nodal index. An energy argument excludes an additional continuously differe...

Evaluating bromeliads as environmental reservoirs for Batrachochytrium dendrobatidis and amphibian disease dynamics in equatorial forests

Abstract The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) is widely distributed across tropical ecosystems, yet the microhabitats that facilitate its environmental persistence remain poorly understood. We evaluated Bd detection in bromeliad tank contents and infec...

Machine learning-assisted mRNA vaccine pharmacovigilance: a systematic review of multi-source real-world data

Abstract Background The rapid deployment of mRNA vaccines during the COVID-19 pandemic exposed limitations in traditional pharmacovigilance systems, including delayed reporting, high underreporting rates, and inability to calculate true incidence. Machine learning (ML) offers new...

Investigations of Pseudo-Shouten symmetric spacetimes in f ( R )-gravity vacuum solutions

Pseudo-Schouten symmetric spacetimes are examined under a differential condition on the Schouten tensor, producing explicit relations for the scalar curvature, the Ricci tensor, and the associated covector field. It is shown that the associated covector is a Ricci eigenvector and...

Integrated endocrine–oxidative–metabolic and trace element responses to heat and cold stress in dromedary camels (Camelus dromedarius)

Abstract Background The dromedary camel ( Camelus dromedarius ) possesses remarkable physiological adaptations to withstand harsh desert conditions, including heat stress and drought. This study aimed to evaluate the effects of heat and cold stress on oxidative stress biomarkers,...

Undetected Gastric Angiodysplastic Lesion Causing Obscure Gastrointestinal Bleeding

Obscure gastrointestinal bleeding (OGIB) has traditionally been defined to as bleeding originating from the small intestine that is beyond the reach of esophagogastroduodenoscopy and colonoscopy. However, gastric lesions associated with chronic intermittent bleeding may be undete...

Research catalogue: twelve public preprints and their verified repository links, 9 September 2026

A dated finding aid to twelve public research preprints by R. E. W. Kho. This catalogue is not an additional research study, a journal-acceptance list, or evidence of peer review or clinical benefit. It includes the new incomplete radiology evaluation and the correction of unsupp...

Design and Implementation of the Zero-Query Name System (ZNS): Evaluating Transport-Independent State Replication Against Distributed DNS Querying

The Domain Name System (DNS) operates on a distributed request-response paradigm formulated under the constraints of 1980s network topologies: resolvers issue queries over the network, cache answers for a bounded Time-To-Live (TTL), and re-query upon expiration. While resilient,...

Medicaid ACO Implementation and Pediatric Asthma Care Equity

OBJECTIVES: Poorly controlled asthma disproportionately impacts children from lower-income and racially or ethnically minority groups. We examined whether Massachusetts Medicaid Accountable Care Organization (ACO) implementation was associated with improved pediatric asthma care...

A cyanate-bridged binuclear center in bovine cytochrome c oxidase

Cytochrome [Formula: see text] oxidase (C[Formula: see text]O) catalyzes the four-electron reduction of oxygen to water while coupling this reaction to proton translocation across biological membranes. The catalytic chemistry occurs at the binuclear center (BNC), composed of heme...

The landslide dam breach disaster in Hualien, Taiwan on 23 September 2025

Abstract Landslide damming is a typical landslide hazard chain in regions with strong tectonic activities or frequent rainstorms. On 19 July 2025, Typhoon Wipha caused severe rainfall in Hualien, Taiwan, triggering the largest landslide (23.715°E, 121.299°N) (about 290 × 10 6 m 3...

Solving the standing-start paradox in track cycling

Abstract Standing starts in track cycling appear paradoxical: a departure ‘from rest’ can exhibit a non-zero bike velocity at the official signal. We resolve this apparent contradiction by identifying a brief transitional regime, initiated around the gate-release window and prece...

MULTIPATH PROPAGATION'S IMPACT ON ESTIMATING THE SIZE OF UNDERWATER NETWORKS

Abstract The number of node (cardinality)’ is an important operation parameter in networks, and the parameter can be obtained through conventional protocol-based approaches, yet these methods have several drawbacks for underwater presence, including great propagation delay, high...

Spatial distribution modeling of the Barbary sheep (Ammotragus lervia) under current and future climate conditions in the Chihuahuan Desert, Mexico

Context Dryland ecosystems are highly vulnerable to biological invasions because of strong climatic constraints and limited resource availability. In the Chihuahuan Desert, the introduced ungulate Ammotragus lervia represents an increasing conservation concern owing to its potent...

Organic Room-Temperature Phosphorescence and Triplet-Singlet Energy Transfer in Aqueous (Bio)templated Coassemblies

Abstract We report here (bio)polymer-template-induced generation of room-temperature phosphorescence (RTP) in trimeric halogenated phenylpyridinium derivatives in aqueous media and in the film state. For this purpose, two different types of anionic templates were introduced: hepa...

Serial optical coherence tomography angiography reveals progressive retinal reperfusion and structural recovery following immunosuppressive therapy in pediatric bilateral occlusive retinal vasculitis

Abstract We report a case of bilateral occlusive retinal vasculitis in a previously healthy 6-year-old girl who developed severe visual loss 7 days after streptococcal infection. At presentation, best-corrected visual acuity was 0.125 in the right eye and 0.08 in the left eye. Fu...
