Polystyrene microplastics alter the accumulation and elimination dynamics of silver nanoparticles in Daphnia magna

Environmental context Microplastics are widespread aquatic contaminants that can alter the environmental behavior of co-occurring pollutants. This study shows that polystyrene microplastics substantially modify silver nanoparticle bioaccumulation in Daphnia magna, increasing wate...

Using PTL Architecture and Surface Chemistry to Control the Nucleation, Distribution, and Morphology of Self-Supported PGM-Free AEM Cathodes

Abstract Self-supported electrodes are increasingly being used in anion exchange membrane electrolyzers. However, a clear understanding of the effects of substrate chemistry and structure is lacking. NiMoO4 nanorods were hydrothermally grown from sodium molybdate and ammonium hep...

Trajectories of physical activity and screen media use in toddlers and related parenting practices: Child and Mother Physical Activity Study (CAMPAS)

<title>Abstract</title> <bold>Background:</bold> Physical activity (PA) and screen media use are key behaviors for healthy development in early childhood. This study aimed to investigate 12-month trajectories of PA and screen time among toddlers and examine their associations wit...

Efficacy of rTMS in Post‐Stroke Bilingual Aphasia: A Single Case Experimental Design

BACKGROUND: The application of non-invasive brain stimulation in the rehabilitation of bilingual individuals with aphasia following a stroke is understudied. Recent studies show benefits of anodal cerebellar transcranial Direct Current Stimulation in bilinguals, while in monoling...

Development and Evaluation of a University-Based External Coaching Program for School Behavioral Health

School behavioral health (SBH) systems coaching is a developing approach to implementation support for the delivery of high-quality behavioral health support in schools through a multi-tiered prevention and intervention framework. Articulating coaching components and understandin...

Aphasia treatment research: a decision-making tool to guide the design of phased trials from the Collaboration of Aphasia Trialists (CATs) trials for aphasia panel

Background Systematic reviews of randomised controlled trials with meta-analyses indicate that speech and language therapy for aphasia after stroke is effective in improving communication. However, high-quality evidence to identify an intervention’s target population (who), regim...

Quantifying and Counteracting the Impact of Erroneous and/or Incomplete Information via High-Order Predictive Modeling: Methodology and Illustrative Applications to Nuclear Reactor Models

This work highlights the major benefits of applying the “Fourth-Order Best-Estimate Predicted Results with Reduced Uncertainties Predictive Modeling” (4th-BERRU-PM) methodology to quantify and remedy the impact of possibly faulty computational or experimental information. After d...

Prevalence and risk factors of falls among older adults in the United States: a cross-sectional study

Several studies have examined falls among older adults in the United States; however, studies using recent nationally representative data to evaluate fall prevalence and associated factors in this population are limited. We investigated the current prevalence of falls among older...

Exploring the role of place visitation big data on small area health measure estimation

Population-level health measures at small geographic scales (e.g., census tracts), including health conditions, preventive behaviors, risk factors, and overall health status, are crucial for guiding effective health planning and policymaking. It has been well established that dem...

Residential Context and Survival Disparities in Black and White Women With Ovarian Cancer

Importance: Black women with epithelial ovarian cancer (EOC) have significantly worse survival than White women. How residential context contributes to these disparities is unclear. Objective: To examine whether there is an association of residential context with racial dispariti...

Autoimmune diseases involving the gastrointestinal tract: clinical patterns, imaging spectrum, and complications

Autoimmune diseases frequently involve the gastrointestinal (GI) tract and can present with nonspecific symptoms that delay diagnosis. Their manifestations range from subtle motility disturbances to life-threatening ischemia, perforation, or obstruction. Advances in cross-section...

Plant hormone manipulation impacts salt spray tolerance, which preempts herbivory as a driver of local adaptation in the yellow monkeyflower, Mimulus guttatus.

A major challenge in evolutionary biology is identifying the selective agents and phenotypes underlying local adaptation. Local adaptation along environmental gradients may be driven by trade-offs in allocation to reproduction, growth, and herbivore resistance. To identify enviro...

Antecedents and outcomes of corporate digital social responsibility in hospitality and tourism: a systematic review and integrative framework

This study synthesises corporate digital social responsibility (CDSR) research in hospitality and tourism and proposes an integrative framework linking antecedents, digital design characteristics, mechanisms, and outcomes. Using structured search logic and PRISMA-aligned screenin...

What Drives Schoolchildren's Food Choices? Insights from a Gamified Stated-Preference Choice Experiment in Tunisia

This paper models the drivers of schoolchildren's food choices in urban Tunisia using a gamified Stated-Preference Choice Experiment (SPCE), which includes scenario attributes (food placement, preparation, and price) and contextual factors (parental/peer modeling eating behaviors...

Automated Guided Wave Characterization of Marcelling: In-Plane Fiber Waviness in Thermoplastic Composites

Thermoplastic composite (TPC) materials often develop in-plane fiber waviness during manufacturing, a defect known as marcelling. Marcelling negatively impacts the strength and overall performance of the composite and are hard to control. While it may appear as a surface imperfec...

Perceived Effectiveness of Cigar Warnings Among Young People in the U.S.

Introduction: The effectiveness of warning size and format on cigar packaging in influencing youth and young adult smoking behaviors is not well understood. This study tested these cigar warning characteristics among youth and young adults who use or are susceptible to using litt...
