Dynamic pathways of maternal well-being: A longitudinal latent class analysis of risk and adaptive trajectories in low-income families

Maternal well-being is shaped by a dynamic interplay of structural, relational, and psychological factors, yet most research has examined risk processes across broad economic ranges rather than within families experiencing persistent disadvantage. Grounded in ecological systems,...

Impact of a High‐Fiber, Fruitless Diet on the Gut Microbiome, and Health of Captive Orangutans

ABSTRACT Diet is a crucial factor in modulating the gut microbiome, and understanding these interactions in captive primates is essential for their health and welfare. This study assessed the impact of the transition to a high‐fiber, low‐sugar diet on the gut microbiome, behavior...

Do Kinesiology Students Think Differently About Low Back Pain? Low Back Pain and Spinal Health Beliefs Across University Academic Programs

Low back pain is influenced by physical, lifestyle, and psychological factors. Education in human health is linked to improved outcomes in disability and pain. A survey of 201 undergraduate students documented self-reported low back pain and examined how program specialty, includ...

Electrochemical Nitrogen Reduction to Ammonia with Mesoporous Molybdenum-Carbon Electrocatalysts in a Gas Diffusion Flow Cell

Abstract Commercialization of electrochemical nitrogen reduction (eNRR) is hindered by limited catalyst performance, the lack of scalable electrochemical cell architectures, and an incomplete understanding of performance-limiting processes. This work aims to address these challen...

Process-based evaluation of green roof models for assessment of heat mitigation efficacy in WRF (v4.3.1) and EnergyPlus (v8.6.0)

Abstract. Green roofs mitigate urban heat, but to fully assess their impact, green roof models must be integrated into urban climate models, where they provide critical surface boundary conditions. Ensuring their reliability requires evaluation, yet such efforts remain limited in...

Thermal stability and CO₂ adsorption–desorption performance of synthetic hectorite and its CeO₂/NiO nanocomposites

Understanding the properties of clay minerals is crucial for developing efficient adsorbent and catalytic materials, creating new options for carbon capture technologies (CCT). This study investigates for the first time the thermal stability of synthetic hectorite (Hec), a smecti...

Light‐Weight Sustainable Composite From Virgin and Recycled Polypropylene Blends and Biocarbon for Automotive Part Application

ABSTRACT This work develops lightweight, sustainable PP/rPP/biocarbon composites targeting automotive applications. Virgin PP was blended with automotive recycled PP (rPP) at 70/30 and 50/50 ratios; the 50PP/50rPP blend exhibited the highest impact strength (31.54 J/m) with accep...

Descriptive analysis of dairy cow imports from the United States into Ontario, Canada between 2009 and 2019: implications for the risk of H5N1 introduction

Since first being identified in March 2024, infections of highly pathogenic avian influenza (H5N1) have been reported in over one thousand dairy herds in the United States. Canadian dairy cattle have remained free from H5N1 infection, due in part to the testing regulations for in...

Physics-guided residual regression and empirical-error-constrained design exploration for frp-reinforced concrete slab–column connections

Abstract Punching shear is a brittle limit state in concrete flat slabs, and its assessment is still uncertain when fiber-reinforced polymer (FRP) bars replace steel flexural reinforcement. This study develops a physics-guided residual-ridge model for interior, concentrically loa...

A Novel Neurodynamics-Based Approach to Fatigue-Aware Motion Planning in Human–Robot Collaborative Assembly

This paper proposes a neurodynamics-based motion planning framework for fatigue-aware human–robot collaborative assembly (HRCA). The proposed framework integrates human fatigue information into robot motion planning to generate fatigue-dependent trajectories with adaptive clearan...

Mergers Fall Short: Nonmerger Channels Required for Galactic Heavy Element Production

Abstract Since the discovery of the binary neutron star merger GW170817 and its associated kilonova, neutron star mergers have been established as a key production channel for r -process elements in the Universe. However, multiple lines of evidence, including the observations of...

Pheromone and morphometric features of honey bee (Apis mellifera) queens imported to Canada from around the globe

Canada imports approximately 300,000 honey bee queens annually to support the beekeeping industry, in addition to producing queens domestically during the short rearing season. Over 80% of imported queens come from the U.S., with additional contributions (~5% each) from Italy, Au...

Spatially explicit modeling of future land use and land cover dynamics in the São Francisco River Basin, Brazil

Future land use and land cover (LULC) changes in major Brazilian river basins may pose substantial challenges for water resource management by altering streamflow regimes, reducing water availability, affecting ecosystem services, and increasing pressure on vulnerable hydrologica...

Revisiting the relation between oral contraceptive use and attentional engagement in everyday life: The role of formulation

Oral contraceptives (OCs) are composed of artificial estrogen (ethinyl-estradiol) and/or progesterone (progestin), which can attach to receptors in the brain and potentially influence cognition. One prior study suggested that OC use was associated with increased mind-wandering –...

Geochemical modelling of coupled sulfide–silicate systems during sulfuric acid leaching of Ni-, Co-, and Mn-bearing minerals

Abstract The increasing demand for critical metals such as nickel (Ni), cobalt (Co), and manganese (Mn) has highlighted the need for efficient hydrometallurgical recovery from low-grade sulfide resources and mine wastes. Although sulfuric acid leaching is widely used for metal ex...

Spatial responses of ecosystem services to future climate change across China in the mid-21st century

Accurately identifying ecosystem-service (ES) responses to future climate change is essential for improving ecological conservation and restoration and for developing targeted adaptation strategies. However, coherent future response zones across multiple regulating services and t...

Comparison of arterial blood pressure and quality of induction and recovery in horses anesthetized with diazepam or guaifenesin co-induction combined with xylazine and ketamine and maintained on isoflurane.

= 0.004) arterial pressures decreased significantly at 20, 30, and 40 min in Group D. Dose of dobutamine and/or phenylephrine was similar between groups. Sedation, induction, and recovery scores were similar. Induction scores were good to excellent [both groups: 0.5 (0, 2); media...

PS12-11. Prepartum Rumen-Protected B Vitamin Complex Supplementation Improves Maternal Reserves, Colostrum Yield, and Reproductive Responses in Beef Cows.

Abstract Late gestation is characterized by increased metabolic demands that may compromise maternal reserves and influence fetal development and postpartum performance in beef cows, and B-complex vitamins act as essential cofactors in oxidative metabolism, gluconeogenesis, and o...

44. A Benchmark Study of Feeding and Management Practices, Feed Utilization, and Adoption of Growth-enhancing Technologies by the Canadian Feedlot Industry.

Abstract The Canadian feedlot industry is exceptionally diverse, in both operational practices and feeding management. Previous Canadian feedlot industry surveys lacked detailed information on feed ingredient usage, feeding management, and the use of growth and health enhancing t...

52. Transferability of Methane Emission SNP Effects from Dairy to Beef Cattle Populations.

Abstract Transferring single-nucleotide polymorphism (SNP) effects across cattle breeds has often proven to be unreliable for a range of traits, even when using higher-density SNP panels. However, methane production (MeP) may exhibit greater portability across breeds because it h...
