Taguchi-Optimized Green Synthesis of a Novel Nickel-bis-thiazoline Complex: A Bifunctional Platform for Sustainable Ullmann-type N-Arylation and Antibacterial Applications

A novel bis-thiazoline ligand and its nickel(II) complex were synthesized via an environmentally benign and mild protocol.Synthesis parameters were systematically optimized using the Taguchi Design of Experiments (DoE), achieving high yields (> 98%) and ensuring a scalable, repro...

A short note on differential equations and on Geometry

A short note on differential equations. We add some lines of interest about Some topics in Geometry.

A standardized permafrost ground temperature collection for Canada 2025

Abstract. Ground temperature is an essential variable for monitoring the thermal state of permafrost, developing models, and conducting fundamental research. However, the usability of GT data in Canada is often hampered by inconsistent file formats, a lack of metadata standardiza...

Ultraprocessed Food Intake and Adiposity, Vascular Brain Injury, and Cognition in Middle-Aged Adults

Importance Ultraprocessed foods (UPFs) account for a substantial and increasing proportion of dietary intake in Canada. Although UPFs are consistently associated with adiposity and cardiometabolic disease, their associations with subclinical vascular brain injury (VBI) and cognit...

Use of Telestroke Prior to Endovascular Stroke Treatment in Canada: Results from the OPTIMISE Registry

BACKGROUND: Telestroke allows rapid assessment of acute stroke patients for intravenous thrombolysis and endovascular thrombectomy (EVT). While its safety and efficacy for thrombolysis are well established, evidence regarding EVT decision-making via telestroke is scarce. METHODS:...

Distal Radial Access for Thoracic Branch Endoprosthesis Deployment: Two Cases of Successful TEVAR with Left Subclavian Artery Revascularization

Background and Clinical Significance: Thoracic endovascular aortic repair (TEVAR) involving zone 2 of the aortic arch frequently necessitates left subclavian artery (LSA) revascularization to reduce the risk of neurologic and ischemic complications. If endovascular methods are em...

Short Communication on Email Management Systems

We present the opportunity to Manage Emails with More in-depth Computing Systems. Many options and examples are of interest.

Improving the CLASSIC (v1.8) snow model to better simulate Arctic snowpacks

Abstract. This study enhances the snow model of the Canadian Land Surface Scheme including Biogeochemical Cycles (CLASSIC), with a particular focus on Arctic environments. Key snow model physics improvements include adjustments to the thermal conductivity at the top of the first...

Field experiments predict ecological response to a large-scale epidemic of an anti-keystone pathogen

Knowledge of how pathogens, in the context of a changing environment, shape the structure of ecological communities remains limited, and little information exists on the ability of small-scale field experiments to predict the consequences of large-scale environmental impacts. We...

Short Communication on Objects Found on Road

We have found some Objects on Road in Montreal City. Some Remarks are made.

Optimizing HIV testing uptake among pregnant women in Burkina Faso: machine learning prediction and scenario-based intervention simulations using 2021 Demographic and Health Survey data

HIV testing uptake among pregnant women remains a public health priority in Burkina Faso. This study aimed to identify and rank key predictors of HIV testing uptake using machine learning (ML) approaches and to estimate potential gains under scenario-based intervention simulation...

Did Congress Trade Ahead of the 2026 Iran War? Disclosure Delays and the Value of Early Entry

Did Congress trade ahead of the 2026 Iran War? We examine 135 disclosed transactions made by members of Congress in ten geopolitically exposed industries during the escalation. Members traded heavily in industries that subsequently rose, and congressional trading volume peaked ro...

Impact of Primary Health Care Reforms in Quebec’s Health Care System: A Systematic Review

Introduction: Primary health care (PHC) reforms in Quebec between 2000 and 2023 aimed to improve accessibility, continuity, efficiency, and equity through organisational transformation, notably the Family Medicine Groups (FMGs), centralised waiting lists (Guichets d’accès), the a...

Exploring the Mechanisms of in-Hospital Emergency Department Diversion: A Qualitative Single-Case Study

Healthcare workers (HCWs) are at risk of substance use disorders (SUD) due to factors such as burnout, stress, and occupational trauma, which may contribute to drug diversion (theft or unauthorized redirection of controlled substances), placing HCWs at risk of overdose, death, pr...

Multivariate analysis identifies distinct latent components and highlights the contribution of motor cortex neurochemistry to clinical variance in amyotrophic lateral sclerosis

Abstract Amyotrophic lateral sclerosis (ALS) is marked by substantial clinical heterogeneity across motor and extramotor domains, yet how different neuroimaging modalities jointly relate to this heterogeneity remains poorly understood. Prior ALS neuroimaging studies have largely...

Early-life microbiota direct an epithelial S100 program required for neonatal immunity

Despite appreciation that neonatal immune responses differ markedly from those of adults, the mechanisms that enable early-life immunity remain poorly understood. Here, we find that healthy newborn mice express high concentrations of the S100 calcium-binding protein A8/A9 (S100A8...

Sleep Healthy Using the Internet: A Meta-Analysis of Twenty Years of Research on a Digital Cognitive Behavioral Therapy for Insomnia Program

Abstract Study Objectives To summarize two decades of research on Sleep Healthy Using the Internet (SHUTi), among the most-studied digital Cognitive Behavioral Therapy for Insomnia programs. Methods PubMed, CINAHL, Web of Science, and PsycINFO were comprehensively searched throug...

A global consistent database of plankton and detritus from in situ imaging by the Underwater Vision Profiler 5

Plankton and detritus are essential components of the Earth's oceans influencing biogeochemical cycles and carbon sequestration. Climate change impacts their composition and fluxes, and marine ecosystems as a whole. To improve our understanding of these changes, standardized obse...

Adjuvanted Influenza Vaccines Versus Other Influenza Vaccines in Adults Aged ≥60 Years: A Systematic Review and Meta-Analysis of Relative Effectiveness for Preventing Influenza-Related Hospitalization
