Obscured Rhythms: Using Rhythmanalysis to Understand How Symptoms Associated With Menopause Shape Everyday Experiences of Physical Activity

Physical activity (PA) is frequently promoted as a means of managing symptoms associated with the menopause transition (MT), yet little is known of how the embodied, emotional and temporal disruptions of menopause influence the experiences of, and possibilities for, movement. Tak...

270. Performance of Early-Weaned Beef Calves Grazing Annual Ryegrass Under Different Concentrate Supplementation Strategies.

Abstract The objective of this study was to evaluate the effects of concentrate supplementation levels and delivery strategy on the growth performance of early-weaned beef calves grazing annual ryegrass (Lolium multiflorum). Three experiments were conducted at the UF/IFAS Range C...

Incidence and Predictors of Complications After Transcatheter Aortic Valve Implantation According to VARC‐3 Criteria: A Systematic Review and Meta‐Analysis

BACKGROUND: Despite continuous advancements in devices and techniques, transcatheter aortic valve implantation remains associated with complications impacting outcomes. In 2021, the Valve Academic Research Consortium (VARC) introduced the VARC-3 criteria to better classify proced...

Patient Risk Factors for Incidental Pathology After Uterovaginal Surgery for Apical Prolapse: Systematic Review and Global Expert Consensus Statements

Abstract Introduction and Hypothesis Uterus preservation is increasingly used for uterovaginal prolapse (U-POP) repair despite ongoing concerns regarding future uterine, cervical, and adnexal pathology. We evaluated incidental pathology rates, associated risk factors, and created...

Awareness, interest and use of a hospital-based overdose prevention site in Vancouver, Canada: a cross-sectional study

An overdose prevention site (OPS) was implemented as a harm-reduction strategy to mitigate the consequences associated with the injection of substances at one Canadian hospital. This study sought to examine awareness, interest, and use of a hospital-based OPS among individuals wh...

Antibiotic-directed polymerization enables tunable antibacterial polydopamine coatings

Polydopamine (PDA) is a nature-inspired coating material due to its strong adhesion, excellent biocompatibility, and rich surface chemistry; however, pure PDA generally exhibits limited intrinsic antibacterial activity. In this study, PDA coatings containing structurally distinct...

Diminished sialoside binding in novel H5N1 influenza hemagglutinin variants identified in a human patient

In 2024, an adolescent female in British Columbia was hospitalised presenting with severe symptoms including respiratory failure due to infection with a novel H5N1 influenza strain (BC24). Using cryogenic electron microscopy, we show here that the N169 α2,3-linked auto-glycan tha...

Enabling Data-Efficient Machine Learning through Multi-Target Training Set Design via Greedy Neighborhood Coverage

Abstract Machine learning is increasingly used to guide asymmetric catalysis, but each enantioselectivity measurement remains experimentally expensive. Prior work established that predictive accuracy in these datasets is dominated by reactions that are structurally similar to the...

Scalable Fabrication of Piezoelectric Paper Composite: The Interplay of Pulp Fibrillation, BaTiO3 Particle Loading, and Aging Effects of Refined Pulp

Abstract This paper reports the fabrication process of a piezoelectric material with a peak piezoelectric coefficient, d33 = 48 ± 6 pC/N, achieved using highly refined wood pulp at 528 kWh/t specific refinement energy (the highest level tested). The process involves functionaliza...

Vision-Language Model-Based Demonstrators for Imitation Learning in Construction Robotic Timber Assembly

Abstract Intelligent construction robots are deemed the future of on-site construction for improved productivity and safety. To automate the construction process, imitation learning (IL) has been adopted to train construction robots in a repertoire of tasks. However, collecting d...

Dual Compartmentalization of GSTA4 Suppresses Ferroptosis to Drive Antiandrogen Resistance in Prostate Cancer

ABSTRACT Resistance to second‐generation antiandrogens poses a major therapeutic challenge in castration‐resistant prostate cancer (CRPC). While ferroptosis evasion has been implicated in treatment failure, the key molecular determinants driving this evasive process are poorly un...

Biosynthesis of Spatially Differentiated Cellulose for Flexible All‐in‐one Supercapacitors

ABSTRACT Bacterial cellulose (BC) is a sustainable scaffold for flexible energy‐storage devices, but conventional biosynthesis provides limited control over through‐thickness structure, making it difficult to integrate distinct functional regions within a monolithic structure. He...

The spatial lives of a failed idea: US industrial policy after Fordism

This article asks why the US industrial policy debate of the 1970s and 1980s, around an idea widely regarded as a defeated alternative to neoliberalism, nonetheless left a durable imprint on American political economy, using the case as a vantage point through which to develop a...

Do cork oak trees grow in the dry, hot summer of the mediterranean climate?

Abstract Monitoring stem radial intra-annual growth dynamics is a useful approach for characterising tree growth responses to climate change. In the Mediterranean there have been only a few studies reporting growth responses of cork oak ( Quercus suber L.) to seasonal water short...

Projecting Impacts of Marine Heatwaves and Their Effects on Long‐Term Changes in Marine Ecosystems Over the 21st Century

ABSTRACT Marine heatwaves (MHWs) are increasing in frequency, duration and intensity under climate change. Although current MHWs trigger broad ecological impacts, such as coral bleaching, mass mortality of seagrass meadows, and declines in important fish stocks, the cascading eff...

A review of FDG-PET biomarker analysis methods in Parkinson's disease

Despite well-established clinical diagnostic criteria for Parkinson's disease (PD), challenges remain in early-stage diagnosis, differentiating atypical parkinsonism disorders, and understanding of underlying disease mechanisms. Neuroimaging, particularly positron emission tomogr...

Measuring the association between women’s empowerment using SWPER index and utilization of maternal and newborn health services from pregnancy to postpartum in Nepal

Women’s empowerment is a global development priority that serves as both an independent goal and a critical determinant of maternal and newborn health (MNH) outcomes. This study aimed to assess the association between women’s empowerment and utilization of MNH services from pregn...

Challenges in establishing epidemiological cut-off values for the Burkholderia cepacia complex

ABSTRACT The Burkholderia cepacia complex (BCC) is comprised of 24 species of gram-negative bacteria that cause opportunistic infections. While antimicrobial susceptibility testing (AST) has historically been used to guide treatment for BCC infections, recent work highlighting pr...

Instability of thin-film flows with temperature-dependent viscosity

We explore thermo-viscous instabilities in an idealised setting motivated by ice-sheet flow, modelled as a shallow layer of fluid with a temperature-dependent viscosity flowing down an inclined plane and subject to a constant geothermal heat flux. In this setting, multiple steady...

Physics-Informed Machine Learning Overcomes Particle-Size Nonlinearities That Confound the Raman Spectrometry of Granular Carbonaceous Materials

Abstract Raman spectroscopy supports multivariate regression models that can offer a rapid and nondestructive approach to quantifying the composition of granular materials. Soils constitute a class of such materials for which chemical analysis provides vital information for agric...
