Gradient Orbital Coupling in Mn‐Doped Asymmetric Units Amplifies Red Emission of NH 4 CdCl 3 for X‐Ray Scintillation Imaging

ABSTRACT Halide perovskites are promising for applications in light‐emitting diodes, multilevel anti‐counterfeiting, and radiation detection due to their excellent luminescence properties. Mn 2+ doping can further tailor the optical properties of perovskites, yet its microscopic...

Cross-sectional evaluation of anthropometric measures vs MRI-measured visceral and hepatic fat in a Canadian cohort

Abstract Context Accurate assessment of excess body fat and its cardiometabolic risk is essential in clinical and epidemiologic research. Body mass index (BMI), although widely used, does not capture visceral or ectopic fat. Objective To evaluate how anthropometric measures—BMI,...

Water Insecurity as Health Crisis: Everyday Embodiment and Gendered Vulnerability Among Girls in Ghana’s Upper West Region

In semi-arid Ghana, girls bear primary responsibility for household water collection in communities without on-premises access, a burden intensified by climate change associated with rising temperatures and frequent droughts. Yet little is known about how this responsibility shap...

Dynamical and conformational behavior of a polymer in a crowded solution

We investigate the structure and dynamics of a polymer in a fluid containing mobile spherical colloidal crowders of radius R. We compare and contrast the behavior with Langevin dynamics (LD) and lattice Boltzmann molecular dynamics (LBMD), the latter incorporating long-range hydr...

Mapping Nearshore Cladophora in Lake Ontario: An Automated Open-Source Sentinel-2 Workflow and Experimental Index

Abstract. Acquiring high-quality Sentinel-2 images is a key first step for nearshore remote-sensing studies, but scene-level cloud metadata can be misleading when the research window is small. This paper presents an open-source, local cloud-aware workflow for two Lake Ontario reg...

Consumer Perceptions and Behaviors Toward Fermented Foods: Insights From a Canadian Survey

ABSTRACT Chronic and autoimmune diseases continue to rise across Canada, demonstrating the need for sustainable dietary strategies that promote long‐term health. Fermented foods (FFs) have emerged as a potential approach, yet national data on consumption patterns and public perce...

Beyond the Fracture Clinic: 3 Things a Surgeon Can Do to Help Older Patients Stay Out of the Hospital

Musculoskeletal conditions, particularly osteoarthritis, account for >40 million disability-adjusted life years worldwide among persons aged 60 years and above. Research has also demonstrated that up to half of older adults have multimorbidity, which requires optimization for pos...

Response of Tetranychus urticae (Acari: Tetranychidae) to natural products

Abstract The two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), is a cosmopolitan pest of numerous crops, including grapevines, where outbreaks cause leaf chlorosis, necrosis, defoliation, and yield reduction. Intensive use of synthetic acaricides has led to res...

Characterisation of the HLA‐DPA1*01:194:01:02 Allele by Next‐Generation Sequencing

Novel HLA-DPA1*01:194:01:02 allele identified in Canadian liver transplant candidate of European descent by next-generation sequencing.

The cognitive architecture of degraded speech intelligibility

Accurate speech understanding is crucial in everyday life. Yet, speech is often degraded by a variety of talker and environmental factors, which listeners must overcome. In this online experiment, we assess how degraded speech intelligibility is supported by “elemental” cognitive...

Jack Halpern

Abstract Jack Halpern was the leading expert in applying kinetics and thermodynamics to establish the intellectual framework of modern catalytic science and the constituent elementary steps in homogeneous catalysis. He had a most impressive ability to identify the core of a mecha...

Engineering antigenic breadth against SARS-CoV-2 by pairing divergent RBDs within a single mRNA immunogen

Abstract Vaccines capable of eliciting broadly neutralising antibodies (bnAbs) are a major goal for pandemic preparedness. A persistent challenge across vaccine Wields is how to deliberately recruit the rare B cell clones that recognise conserved epitopes shared across diverse vi...

SynBio 8.0: A Portrait of a Growing Canadian Ecosystem

The 8th edition of the Annual Canadian Synthetic Biology Symposium (SynBio 8.0) was hosted at the University of Waterloo from June 15 to 17th. It brought together around 140 attendees from across Canada, as well as international participants. Organized by the Waterloo Centre for...

Finite-field QED corrections to vacuum birefringence and magnetar polarization transport

Abstract We study low-energy photon propagation in a constant magnetic field within the finite-field one-loop Heisenberg–Euler framework and apply the resulting mode-dependent refractive indices to magnetar polarization transport. In a centered-dipole model, the polarization-limi...

Multi-modal machine learning for prediction of post-anesthesia care unit recovery time

Abstract Background Efficient recovery management in the Post-Anesthesia Care Unit (PACU) is important for patient safety and care coordination, yet estimating recovery duration remains challenging. Traditional regression models and discharge scoring systems have shown limited ac...

Deep reinforcement learning for optimizing mobile depots allocation and hybrid order dispatch in last-mile delivery under multi-participants behavioral uncertainty

As last-mile delivery demand continues to grow and customer preferences become increasingly diverse, traditional single-mode logistics systems are inadequate in addressing the complexity and variability of modern urban delivery environments. In this paper, we propose an innovativ...

Spatiotemporal complexity of soluble reactive phosphorus behaviour within cold climate field-scale bioretention systems

Bioretention systems are widely implemented to improve urban runoff quality, yet the fate of phosphorus (P) within these systems remains poorly understood, particularly under field conditions in cold climates. This study investigated the spatiotemporal behaviour of soluble reacti...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

ABSTRACT Nanophotonic lenses are transformative optical elements for nanoscale light manipulation and miniaturized optical systems. For a given material platform, the finite thickness of a planar metalens limits the phase and group‐delay response available for simultaneously achi...

Social Performance Feedback and Managerial Moral Self-Regulation: The Microfoundations of Corporate Social (Ir)Responsibility

Despite growing interest in the microfoundations of corporate social activities, prior research has not articulated the full chain connecting firm-level conditions to managers' psychological processes (a topdown pathway) and back to firm-level corporate social behavior (a bottom-...

Exercise and Brain Health in Postmenopausal Women: A Review of Cognitive Benefits, Mechanisms, and Neurodegeneration Prevention

Menopause represents a major neuroendocrine transition characterized by substantial hormonal, metabolic, vascular, and inflammatory changes that may increase vulnerability to cognitive decline and neurodegenerative disease. Declining estrogen levels during the menopausal transiti...
