Vaccination Unavailability or Delayed Vaccination: Two Plausible Pandemic Scenarios Applied to the COVID-19 Outbreak in Puerto Rico

This study examines two plausible pandemic scenarios, vaccine unavailability and delayed vaccination, using deterministic compartmental models calibrated to the COVID-19 pandemic in Puerto Rico. An SEIsIaHRD model for the pre-vaccination phase and an SVEIsIaHRD model (susceptible...

LLM-Mediated Findability of Research Datasets

This study evaluates the LLM-mediated findability of research datasets. The sample uses 100 datasets randomly selected from GESIS. Experiments were run using web-search-based models from OpenAI and Gemini. Six different query strategies combine metadata such as topic, geography,...

A unified and accurate approach to simulating monotonic and cyclic failure effects of metallic and concrete materials

Purpose A unified and accurate approach is established for the purpose of simulating monotonic and cyclic failure effects of metallic and concrete materials based on an all-through strength-degrading elastoplasticity model. This new model makes no reference to any usually postula...

Mathematical Analysis of Multi-Route Tuberculosis Transmission with Airborne Environmental Reservoirs and Treatment Failure

Despite the availability of effective treatment, tuberculosis (TB) remains a major public health problem worldwide. Related factors that promote continued transmission include treatment failure, residual infectiousness during treatment, environmental contamination, and progressio...

E8 Phase-Locked Resonance Principle — E8 Intelligence Research

The 240 root vectors of the E8 lattice form a closed reflection group that, when excited at the base frequency of 132 Hz, establish a self‑consistent standing wave pattern. Adjacent root vectors couple with a phase offset proportional to the golden ratio φ, producing a globally c...

Budget Transparency and the Prevention of Fund Misuse in Student Organisations: A Citizenship Perspective on Civic Integrity

Misuse of student organisation funds often starts small. This article draws on two online interviews with student organisation leaders and a review of related studies on student organisation finance, nonprofit fraud, and citizenship. It suggests that clear budget reports, members...

Axial Length–Adjusted Normative Reference Values for Retinal Layer Thickness in a Population-Based OCT Study

Purpose: To establish axial length-adjusted normative reference values for retinal layer thickness using population-based optical coherence tomography (OCT) data and evaluate their clinical implications in highly myopic eyes. Methods: This cross-sectional study used Korea Nationa...

Composition of the gut microbiota in treatment-naive patients with newly diagnosed type 2 diabetes mellitus

Alterations in the gut microbiota (GM) are increasingly recognized as a key contributor to the pathogenesis of type 2 diabetes mellitus (T2DM). However, its taxonomic composition, as well as the structural characteristics of enterotypes (ETs) and microbiota-based cooperative netw...

Home Learning Environment and School Readiness of Kindergarten Learners in Cordova Central School

This study assessed the influence of the home learning environment on the school readiness of kindergarten learners. Specifically, it described the profile, determined the level of the home learning environment, assessed the level of school readiness, and examined the significant...

Efficiencies of Single-Objective Linear Programing and Multi-Objective Optimization: A Case of Electricity Generation in Thailand

Single-objective linear programming has been employed as an optimization technique for most single-objective problems to obtain the best solutions for further enhancement. Recently, practical problems are required to fulfill more than one objective function. Although repeated app...

Governing artificial intelligence in science: Evidence from a bibliometric analysis of research integrity

The increasing integration of artificial intelligence into scientific research has raised worries about scientific ethics and research integrity. This research offers a thorough bibliometric analysis. Of 2969 publications Scopus index from 2015 until 2025 to examine the field's e...

The truncated Weil quadratic form: inertia, visibility, structural measurements, and no-go theorems for the Riemann Hypothesis

We record observations on the truncated (window) Weil quadratic form that, to our knowledge, are not stated explicitly in the literature as of October 2026, together with negative results and retracted claims. None of this proves or approaches a proof of the Riemann Hypothesis. T...

Long-term variability of Indian monsoon rainfall related to warming of Indian and Pacific oceans

Abstract Summer monsoon rainfall over India, vital for the socio-economic welfare of more than a billion people, exhibits large interannual variability. The sea surface temperatures of the Pacific and Indian oceans have been identified as the two most dominant factors affecting t...

Functional seizures: care experiences of U.S. Veterans and their care partners

Functional seizures (FS) present substantial diagnostic and treatment challenges, particularly for Veterans with multiple medical and psychiatric comorbidities including post traumatic stress disorder, mood disorders and traumatic brain injury. To more effectively care for Vetera...

Dominant-Pole-Based Tuning Criterion for Coordinated Needle–Deflector Control in Pelton Turbines for Hybrid Wind–Hydro Power Systems

The increasing penetration of converter-interfaced renewable generation in hybrid wind–hydro power systems strengthens the frequency-regulation requirements imposed on hydropower plants, particularly in isolated power systems. In Pelton turbine installations, the deflector, tradi...

Heat Perceptions, Behaviors, and Barriers of Unhoused Individuals in Germany

ABSTRACT Heat waves pose critical health risks for unhoused people. However, little is known about how this population perceives and copes with heat, particularly in Europe. Employing a sequential mixed‐methods approach, we investigated dimensions of unhoused individuals’ heat pe...

Smartphone Dependence, Sleep Quality, and Suicidal Ideation Across Adolescence: A Six-Year Longitudinal Study

Suicide is a leading cause of death during adolescence, and both smartphone dependence and poor sleep have been associated with suicidal ideation. However, it remains unclear whether these associations reflect stable differences between adolescents or year-to-year changes within...

HCCO Nanoreactor-Integrated Electrochemical Paper-Based Analytical Device for Anti-EBNA1 IgA Detection toward Nasopharyngeal Carcinoma Screening

Abstract Serological detection of anti-Epstein–Barr virus nuclear antigen 1 immunoglobulin A (anti-EBNA1 IgA) is clinically relevant to nasopharyngeal carcinoma screening, but conventional immunoassays rely on centralized instrumentation and multistep procedures. Here, we develop...

Influence of high performers on knowledge hiding and seeking of other employees: evidence from China

Drawing on conservation of resources and social comparison theories, this study examines how high-performing coworkers, who occupy more resources, affect the territoriality and knowledge-management behaviors of other employees. Data were collected from 323 employees at three time...

Do high-impact scholars exhibit greater knowledge innovation and flash ideas?

Purpose Knowledge innovation manifests through the emergence of new keyword nodes or relational ties within co-word networks. Such structural changes enable individual scholars to perceive the field’s evolving knowledge architecture and support research teams in tracking innovati...
