Agricultural practices as natural climate solutions in the Canadian Prairies

Management practices focused on environmental outcomes in agriculture can increase soil organic carbon (SOC) and reduce greenhouse gas (GHG) emissions, complementing farm production practices that provide food and a wide variety of other social-ecological services. However, evide...

Statistical Methods for Assessing Non-Replicable, Outlying, and Influential Studies

Quantitative evidence synthesis has become a central tool for integrating findings across multiple studies, multi-centre trials, and multi-source cohort data. However, the identification and interpretation of non-replicable, outlying, and influential studies remain insufficiently...

A Comparison of Machine Learning Models for ICH Prognostication: An Analysis of ATACH-2 and Qatar Stroke Database

INTRODUCTION: Multiple prognostic scores have been developed to predict morbidity and mortality in patients with spontaneous intracerebral hemorrhage (sICH). These scoring models were traditionally based on statistical methods involving a limited set of variables. The advent of m...

The frequency of spawning and skipped migration in a central Canadian population of anadromous Arctic char inferred using acoustic telemetry

Understanding spawning frequency and migration behaviour is essential for managing iteroparous anadromous fishes such as Arctic char (Salvelinus alpinus). Using a decade of acoustic telemetry data from southern Victoria Island, Nunavut, we examined the frequency of marine migrati...

Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles

Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dar...

Cyclic stress–induced Bauschinger effect in wear of in situ formed TiC x -reinforced white iron composite

Abstract Bauschinger effect in wear of in situ formed TiC x /high Cr white iron composite (TiC x /HCWI) against 440C steel counter-ball was studied. Friction coefficients as a function of time and time of changes in direction when cycles numbers (CN) of 0, 1, 2, 5, 10 were tested...

The lingering phenomenon and pattern formation in a nonlocal population model with cognitive map

Abstract The rates at which individuals memorize and forget environmental information strongly influence their movement paths and long-term space use. To understand how these cognitive time scales shape population-level patterns, we propose and analyse a nonlocal population model...

Spleen-derived circulating intercellular adhesion molecule 2 promotes osteosclerosis in chronic myelofibrosis

Abstract Mutations in the gene coding G6b-B, Mpig6b in mice, and MPIG6B in humans lead to myelofibrosis, progressive splenomegaly and osteosclerosis. Aberrant megakaryocyte function in bone marrow and spleen may affect bone cells through cell-cell contact or soluble factors. We a...

Correlates of Multidimensional Sleep Profiles of Young Children

ABSTRACT Despite sleep's multidimensional nature, previous research has focused on correlates of individual sleep dimensions. This study aimed to characterise young children's nighttime sleep profiles based on duration, timing, latency and quality, and to examine potential correl...

Trends in opioid containing drug seizures described as pills between 2020 and 2024 in Canada

People who use drugs may access prescription opioids from unregulated markets to avoid fentanyl and lower toxicity risk, though concerns regarding counterfeit pills have emerged. To better understand the composition of pills that may be circulating in the unregulated drug supply,...

Intersectional futures: gender equity, transgender inclusion, and the politics of sport governance in Alberta

This paper examines the intersection of gender equity, transgender inclusion, and sport governance in Alberta within a broader context of colonialism, misogyny, and digital gender-based violence. Drawing on intersectional feminist theory, critical sport scholarship, and contempor...

A Narrative Inquiry Into the Menopause Experiences of Women With Spinal Cord Injury

Menopause presents distinct medical and social challenges for women with spinal cord injury (SCI), yet little is known about the lived experiences of this population, in part due to gender bias in SCI research and care. This narrative inquiry explores how disability, gender, and...

How to manage: acute-on-chronic liver failure

Acute on chronic liver failure has emerged as a distinct clinical entity over the past few decades. While mortality remains highest for patients who develop liver and multiple non-liver organ failures, earlier recognition of the syndrome, including identification and management o...

Climate, degradation, and biodiversity interactions drive herb biomass in the Hindukush mountain ecosystem

Abstract Understanding the drivers of herbaceous productivity is crucial for managing vulnerable mountain ecosystems under changing climate and land use pressures. This study investigates the direct and indirect drivers governing herb biomass in the Hindukush Himalaya (HKH) using...

From Awareness to Action: Co‐Designing Culturally Safe and Equitable Rehabilitation in Canada – Protocol for the Two‐Phase Ireach Qualitative Study

ABSTRACT Background Inequities in access, engagement, and outcomes persist across outpatient rehabilitation services in Canada, disproportionately affecting Indigenous Peoples, newcomers and refugees, gender‐ and sexually‐diverse individuals, and people with lower income. Althoug...

Unlocking functional potential of underutilized macrophytes: a pyrolysis-based screening approach for resource recovery

Abstract Invasive aquatic macrophytes constitute a significant proportion of biomass waste in tropical and subtropical regions across the world, posing substantial ecological, economic, and public health challenges. Converting these invasive plants into biochar, a porous carbon-r...

Sex Disparity in Enrolment to Clinical Trials for Onchocerciasis and Trachoma

To determine whether female enrolment in randomized interventional clinical trials for onchocerciasis and trachoma reflects the real-world sex distribution of disease burden, and to evaluate sex-based differences across trial characteristics. We performed a cross-sectional analys...

Mechanically Robust and Underwater‐Stable Hydrogels via Synergistic Molecular Locking and Topological Entanglement

ABSTRACT Highly entangled hydrogels typically suffer from swelling‐induced dilution of chain entanglements in aqueous environments, leading to compromised energy dissipation and mechanical integrity. Herein, we report an underwater‐stable and highly entangled poly(acrylamide–acry...

Maternal and fetal cardiovascular response to moderate-to-vigorous intensity exercise in singleton and twin pregnancies

Objective Current guidelines suggest limiting physical activity in pregnant individuals carrying twins but this recommendation is not based on empirical evidence. We assessed maternal and fetal cardiovascular response to submaximal exercise testing in singleton versus twin pregna...

Examining the pregnancy and postpartum experiences of Para athletes in elite sport: a qualitative description study

Objective Pregnancy and postpartum experiences in elite sport remain underexplored for para athletes, despite the unique disability-related demands they face. The purpose of this study was to describe the lived experiences of pregnant and postpartum elite para athletes and to ide...
