A trace pairing and Elliott invariant for groupoid homology

Abstract For an étale groupoid, we define a pairing between the Crainic–Moerdijk groupoid homology and the simplex of invariant Borel probability measures on the base space. The main novelty here is that the groupoid need not have totally disconnected base space, and thus the pai...

Outcomes of living related kidney donors of recipients with familial mediterranean fever-associated Amyloid A Amyloidosis

BACKGROUND: Living kidney donation among carefully selected individuals is generally considered safe but post-donation health risks vary by factors including family history. Data on long-term outcomes of related living kidney donors of recipients with familial Mediterranean fever...

Localization of feline gammaherpesvirus 1 in lymphoid tissues and pulmonary fibrotic lesions of naturally infected cats

Feline gammaherpesvirus 1 (FcaGHV1) is a recently identified member of the Gammaherpesvirinae detected in domestic cats; however, its tissue distribution and pathological relevance remain incompletely defined. This study investigated the localization of FcaGHV1 in naturally infec...

Optimal Size of Electrocorticography Grids for Classification of Hand Movements

Abstract Implanted Brain-Computer Interfaces (BCIs) hold significant promise as a replacement for conventional assistive technologies for people with extensive motor impairments. In recent years, significant progress has been made in enhancing BCI performance, bringing clinically...

Enhanced Photolysisand Photocatalysis Assisted byHydrodynamic Cavitation for the Removal of Methylene Blue Dye

Abstract This study investigates the synergistic integration of hydrodynamic cavitation (HC) with photolysis and photocatalysis to enhance the degradation of synthetic dyes in aqueous systems. Methylene blue (MB) is selected as a model pollutant, and tap water is used as the work...

Temporal trends and age-period-cohort effects of tuberculosis incidence among older adults in western China, 2005–2020

Abstract Background Tuberculosis remains a major public health challenge in China, and older adults in western China bear a disproportionate burden. This study examined the temporal trends in TB incidence among older adults in western China and assessed the independent effects of...

Case-cohort designs to improve efficiency for detecting effect modification

Abstract In analyses of time-to-event outcomes, we may utilize efficient sampling designs to save effort, cost, and valuable specimens. The originally proposed case-cohort design is one such design, and performs analysis on a random sample selected from the full cohort supplement...

Engineering N-site isomerism in donor-acceptor covalent organic frameworks for efficient Fenton-like water purification

Abstract Covalent organic frameworks (COFs) have emerged as promising candidates for singlet oxygen ( 1 O 2 ) generation via peroxymonosulfate (PMS) activation, yet their structure-property-activity relationships remain poorly understood. Herein, three constitutionally isomeric d...

Location-private traffic flow prediction via an encrypted geometric recruitment framework

Accurate traffic flow prediction at specific road segments is essential for optimizing signal control, mitigating congestion, and improving the efficiency of urban transportation systems. Mobile Crowdsensing (MCS) enables large-scale monitoring by collecting geotagged data from p...

What constitutes successful collaborative conjecturing-and-proving processes? Relations between beginning undergraduates’ resources, conjecturing-and-proving processes, and performance

Abstract Students’ difficulties with mathematical argumentation, conjecturing, and proving, as well as with collaborating effectively, have long been documented in the literature. While there is some research on what constitutes successful proving processes, systematic investigat...

Evolution of South Asian mountain biota: dispersal, fine-scale biogeography, phylogenetics and systematics of Nannenini jumping spiders

The northward drift of the Indian subcontinent and its biotic exchanges with adjacent landmasses have shaped biodiversity in South Asia. We investigate biogeographic patterns and evolutionary relationships within a clade of spiders endemic to South Asia, focusing on two newly ide...

Investigating Associations Between Signal Intensity of Silent MR Angiography and Hemodynamic Information From 4D Flow MRI in Brain Arteriovenous Malformation

BACKGROUND: Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. OBJECTIVES: To evaluate the relationship between Silent MRA SI and 4D flow-derived hemodynamic parameters and examine whether Silent MRA-based me...

Parents of youth and young adults with intellectual and developmental disabilities: Barriers experienced during transition

PurposeThe purpose of this study was to explore the experiences of parents of youth and young adults with intellectual and developmental disabilities who have undergone the transition from pediatric to adult healthcare as well as community-based transition and adult-focused servi...

An exploratory multi-indicator assessment of freshwater ecosystem health in two South African reservoirs

Abstract This study assessed freshwater ecosystem health by integrating chemical, biological, and microbial indicators. We conducted an exploratory comparison of Loskop Dam and Nwanedi-Luphephe Dam, South Africa, using water quality parameters, fish Health Assessment Index (HAI)...

Sand Influx Effect on Barchan Steady-state Profile

In this study, based on the crest line model, a differential equation-based mathematical approach to dune dynamics, we investigate the effect of non-contact interactions between barchans through sand flow on their morphodynamics, which is a largely unexplored topic. Numerical cal...

Pharmacotherapeutic Potentials of Spinosaurus Tooth Fossils: Discovering the Ancient Healer

Fossils are generally studied as records of ancient life, geological transformation, and evolutionary history. However, fossilized vertebrate hard tissues such as dinosaur teeth may also be viewed as ancient biomineral systems with potential relevance to pharmacology, biomaterial...

A decision-making architecture for sustainability: Optimization of human resource management with triple bottom line in the extractive sector using a multi-objective approach

Purpose This research develops a mathematical decision-making model to optimise sustainable human resource management (HRM) performance based on the Triple Bottom Line (TBL), using the Iranian oil industry as an empirical case within resource-intensive sectors. Design/methodology...

“But how does flying work on gravity when you just go up?”: An Investigation of Children’s Science Questions While Reading Life and Physical Science Books in Early Childhood

Abstract Children’s question-asking during early childhood plays a central role in cognitive development, reflecting children’s natural curiosity about the world. While research on early science learning has focused on informal contexts (e.g., home) where adults play a key role,...

ECG-based detection of occlusion myocardial infarction: a dedicated deep neural network versus multimodal large language models and physicians — a retrospective diagnostic accuracy study

Abstract Background Accurate electrocardiogram (ECG) interpretation for acute coronary occlusion is a critical, time-sensitive task in emergency care. The field is increasingly shifting from the ST-segment elevation myocardial infarction paradigm to the broader concept of occlusi...

Density Modeling of Sequences: A Path-First Theory of Autoregression, Masked Diffusion, Adaptive Insertion, and the Price of Order

We develop a path-first theory of discrete sequence generation. A generator first defines a probability law on chronology-augmented construction paths; the terminal sequence law is the pushforward of that path law. The full geometric signature faithfully encodes every finite acti...
