The continuum limit of icosahedral Goldberg–Coxeter fullerenes: the flat icosahedron with twelve cone points

Let G_ν = GC_{ν,0}(D) be the Goldberg–Coxeter fullerene of the dodecahedron D, with 20ν² vertices, and let L_ν = 3I − A_ν be its graph Laplacian. Omori, Naito and Tate showed that the bottom o(ν²) eigenvalues tend to 0. We identify the limit of the rescaled bottom spectrum ν²λ_k(...

Carotid energy pulsatility index provides complementary hemodynamic information to renal function in a community-based cohort

Abstract Conventional hemodynamic, including Carotid–femoral pulse wave velocity (cfPWV), characteristic impedance (Zc), and brachial pulse pressure, do not directly quantify pulsatile energy transmission through the arterial system. Carotid energy pulsatility index (PI), derived...

Study on pathways to improve the capacity for vertical collaboration of medical personnel in county-level medical alliances: an empirical exploration based on the CLFI collaboration model

To explore the key factors affecting the vertical collaboration of county and township medical personnel within county-level medical alliances and the paths for improvement, in order to provide suggestions for enhancing the intrinsic motivation for collaboration among county and...

nusantara_motif: a parametric grammar for Javanese batik motifs and its inversion from images

A parametric grammar for five Javanese batik motif families, with an inverse fitter and an image front end, together with the result tables for every number in the accompanying manuscript.

To Tell or Not to Tell: Self-(Non)Disclosure to Parents Across Three Cultures

In Western contexts, self-disclosure is commonly considered beneficial, while nondisclosure is often viewed as dysfunctional. The current research challenges the universality of this assumption about nondisclosure by examining the tendencies, mechanisms, and psychological consequ...

Patterns and Predictors of Repeated Medication Nonadherence in Glaucoma: A Population-Based Study

Background/Objectives: We aimed to evaluate nonadherence to topical glaucoma therapy and identify risk factors for repeated prescription fulfillment failure in a large national population-based cohort. Methods: The electronic medical records from a large health maintenance organi...

Phenotypic, bioactive and metabolomic diversity among indigenous Southern African underutilised monkey orange (Strychnos spinosa Lam.) fruit accessions

Strychnos spinosa Lam. is an indigenous African fruit tree with considerable phenotypic diversity, yet the extent to which visible fruit morphotypes correspond to biochemical and metabolic variation remains poorly resolved. This study integrated fruit morphology, physicochemical...

A Wizard-of-Oz Shuttle as an Experimental Platform for Research on Future Automated Public Transport

Automated public shuttles have the potential to improve road safety, transport accessibility, and passenger experience. However, before such systems can be widely deployed, their sensing, interaction, monitoring, and assistance functions must be systematically designed and evalua...

Beyond the surface: A dual Lens on blog-mediated destination images

This study examines the explicit–implicit duality of blog-mediated destination images. It challenges three traditional assumptions: these images derive from a monolithic source, they are equally accessible, and they primarily concern first-time tourists. Using a mixed-methods des...

The Meaning and Function of Twelve-Step Mutual-Help Groups During Recovery: A 10-Year Qualitative Follow-Up of Persons Treated for Substance Use Problems in Sweden

Background: Twelve-step treatment for substance use problems is a commonly employed intervention in both international and Swedish contexts. An advantage of twelve-step treatment is the possibility of continuing support for the recovery process through participation in mutual-hel...

Phenotypic Associations in Resistance to Medically Important Antibiotics Among Highly Resistant Bacteria Isolated from Cambodian Dairy Farms

Antimicrobial resistance (AMR) is recognized by global health authorities as one of the foremost public health and development challenges confronting humanity today, leading the WHO to establish categories of medically important antibiotics for humans and animals. On farms with a...

Governance innovation for crisis-stricken smart cities: A roadmap to recovery and sustainability

Over the past decade, cities have emerged as centres of economic, social and environmental development. Challenges such as an ageing population, issues of inclusion, evolving poverty, migration patterns and environmental preservation are among the issues urban areas faced. In suc...

Artificial Intelligence for Engineering-Grade Parametric CAD: A Critical Review of Representations, Large Language Models, and Agentic Design Systems

Artificial intelligence (AI) is rapidly expanding computer-aided design (CAD) from shape generation toward generative, conversational, and agentic engineering. However, most AI–CAD evaluations remain dominated by geometric similarity and execution success, while industrial CAD de...

Golden-Ratio Polyhedra as Projections of Higher-Dimensional Lattice Collapse — E8 Intelligence Research

FINDING: The rhombic triacontahedron and its stellations encode φ² and φ³ relationships, with 30 face centers mapping to a 6-cube projection, linking golden-ratio polyhedra to higher-dimensional lattice collapse. | MATH: φ = (1+√5)/2 ≈ 1.6180339887; φ² = φ+1 ≈ 2.6180339887; φ³ =...

The Reciprocal Longitudinal Associations Between Short-Form Video Addiction and Cyberbullying Perpetration Among Vocational School Students

Previous research has demonstrated the prevalence of short-form video addiction and cyberbullying perpetration among adolescents. Nevertheless, longitudinal evidence clarifying the directional associations between the two behaviors, particularly whether such associations reflect...

Increased pathological severity of Familial Dysautonomia enriches murine gut microbial composition

Familial dysautonomia (FD) is the most prevalent type of Hereditary Sensory and Autonomic Neuropathies, which are rare genetic neurological disorders that affect both the peripheral and central nervous systems. Previous studies have found significant alterations in the gut microb...

Firm‐Level Productivity and Stock Return: Evidence from Taiwan

Abstract We examine whether firm‐level total factor productivity (TFP) in Taiwan predicts the cross section of stock returns. We estimate TFP in Taiwan and find that, in contrast to negative relationships documented for US firms, high TFP firms earn higher expected returns than l...

Corrosion–Wear Synergistic Effect of Laser-Clad WC/Ni-Based Protective Coatings on P550 Nonmagnetic Drill Collar

The coupled corrosion–wear damage of P550 nonmagnetic drill collars severely restricts their service reliability in downhole environments. However, the asymmetric synergistic interaction between corrosion and wear, and the underlying microscopic damage mechanism of P550 steel and...

Optimization of expression in Escherichia coli BL21 (DE3), IMAC purification, storage, and preliminary functional characterization of recombinant Chitinase C from Pseudomonas aeruginosa

Chitin is a homopolymer that is found in the abdominal lining and exoskeleton of various insects. Given the increasing environmental pollution due to chemical insecticides used in agriculture, there is great interest in the development of bioinsecticides. Proteins that hydrolyze...
