The Haagerup property is not invariant under quasi‐isometry

Abstract Using the work of Cornulier–Valette and Whyte (see Appendix A for the latter), we show that neither the Haagerup property nor weak amenability is invariant under quasi‐isometry of finitely generated groups. Appendix B shows, using the same examples, that the same holds f...

Characterizing In-Home Safety Challenges and Strategies for Children With Medical Complexity

OBJECTIVES: Medical advances have allowed more children with medical complexity (CMC) to live at home, but previous research has linked implanted tubes to patient safety events. We aimed to characterize challenges and strategies parents use to deliver their children's tube-relate...

Estimating the threat of AI-agent responding across online survey platforms

Recent research and advances in LLMs have led to widespread concern that AI agents could pose as human online survey-takers. However, it remains unclear how prevalent AI agents are on survey research platforms and how to effectively detect AI agents. We validated a series of AI d...

A self-adaptive tube restraint for free-energy calculations along path collective variables

Path collective variables reduce a high-dimensional transition to a progress coordinate, s, and an orthogonal distance, z. Computing the free energy along s often requires restraining z, so that sampling embraces a tube centered on the reference path. However, a conventional fixe...

Caregivers in a Haystack? Informatics‐Driven Clinical Trial Enrollment of Dementia Caregivers at Medical Visits

BACKGROUND: Caregiving status is not routinely documented during clinical care, rendering caregivers difficult to identify for research and supportive interventions. We describe two informatics-based strategies for identifying dementia caregivers at their own or their care recipi...

Kynurenine Pathway Activation is Associated with Poor Sleep Efficiency in Men With HIV

Background: Sleep disturbances are common in people with HIV, yet the underlying biological mechanisms remain poorly understood. Chronic immune activation in HIV can induce the tryptophan-kynurenine (TK) pathway, which both reduces melatonin synthesis and increases production of...

Association Between Interhospital Transfer, Readmission, and Inpatient Mortality Among Older Adults

ABSTRACT Background Interhospital transfer (IHT) is a key strategy for providing access to specialty care; however, it is associated with multiple adverse outcomes, including prolonged length of stay, increased risk of inpatient mortality, and reduced rates of discharge home, par...

Closing Care Gaps in Precision Oncology Through Application of Language-Based Artificial Intelligence

Artificial intelligence (AI) has the promise to close gaps in the delivery of precision cancer care. While general purpose large language models (LLMs) rely on manual prompts, they lack integration into clinical workflows, often producing inconsistent outputs. However, when optim...

“My Existence is Queer”: Understanding Trans and Nonbinary College Students’ Sexual Identities

Scientific practices surrounding sexual identity are largely based upon cisheteronormative assumptions, using terms that may not resonate with − or may exclude − trans and nonbinary (TNB) individuals and their experiences. This exploratory study examined how TNB college students...

Refining implementation determinants and strategies to scale a participation-focused assessment option for family-centered care in early intervention

Indication-Specific Adverse Events and Temporal Trends of Lumen-Apposing Metal Stents: A National Postmarketing Surveillance Analysis (2020–2025)

Background and Aims: The AXIOS stent is a lumen-apposing metal stent widely used for EUS-guided drainage of pancreatic fluid collections, biliary drainage, and gastroenterostomy. We analyzed device problems and patient adverse events reported to the FDA MAUDE database (2020–2025)...

Comparing Three Delivery Formats of a Fatigue Self-Management Intervention: Findings from a Non-Inferiority Randomized Trial

Symbolic ensemble learning enables discovery of fast accurate physics-based interatomic potentials

Machine learning has transformed materials simulation by delivering force fields with ab initio accuracy, yet bridging the gap between high-dimensional regression and physical interpretability remains a grand challenge. Conventional analytical potentials offer transparency but of...

Lateral sclerosis in amyotrophic lateral sclerosis is an upper motor neuron distal axonopathy (“dying back”): a clinical-neuropathological study

Abstract The hallmark neuropathological feature of upper motor neuron (UMN) degeneration in amyotrophic lateral sclerosis (ALS) is the “sclerosis” of the lateral corticospinal tract (CST)—the major axonal pathway connecting UMNs to lower motor neurons (LMNs). However, few studies...

Facilitating best practices in practicum training in clinical neuropsychology: introducing the North American Association of practicum sites in neuropsychology (NAPSN) organizational training guidelines

INTRODUCTION: The North American Association of Practicum Sites in Neuropsychology (NAPSN) was established in 2023 to support external practicum programs in urban, suburban, and rural areas in the United States and Canada by providing resources for member practicum programs and s...

Targeted Analysis of >1500 Plasma Proteoforms via Individual Ion Mass Spectrometry

Abstract Plasma proteomics has emerged as a powerful approach for interrogating human biology, identifying disease-associated proteomic changes, and advancing precision diagnostics. In recent years, affinity-based plasma proteomics platforms with predefined protein panels, such a...

The Identification of the Dynamic Discrete-Choice Model with Stockpiling

We study the identification of the discount factor for dynamic discrete-choice (DDC) models of demand with stockpiling of a storable good. We show that the DDC has built-in exclusion restrictions that set-identify the discount factor without requiring any auxiliary assumptions. W...

Gut microbial metabolism of amino acids and its impact on enteric infections

ABSTRACT Amino acids are the fundamental building blocks of proteins. Dietary proteins and endogenous protein turnover are the main sources of amino acids in the body. Over the past decade, our understanding of the role of the gut microbiota in amino acid metabolism has expanded...

Self-starter or sidekick? Independent and spillover effects of Opportunity Zones on housing supply in cities

The Opportunity Zone (OZ) program, created under the 2017 Tax Cuts and Jobs Act, offers capital gains tax incentives to encourage investment in low-income communities. While proponents argue the program catalyzes new development, critics contend it may subsidize projects that wou...

Impact of cervical cancer–related stigma on screening uptake in Dakar and Kedougou, Senegal: A context-specific stigma index

Cervical cancer is a major public health problem, but it can be prevented through screening and treatment of precancerous lesions. The aim of this study was to assess the association between cervical cancer-related stigma and prior cervical cancer screening uptake among women in...
