Variations in perfusion detectable in advance of microstructure in white matter aging

Author(s): Robinson TD; Sun YL; Chang PTH; Gauthier CJ; Chen JJ;

One of the most promising interventional targets for brain health is cerebral perfusion, but its link to white matter (WM) aging remains unclear. Motivated by existing literature demonstrating links between declining cortical perfusion and the development of WM hyperintensities, we posit that regional WM hypoperfusion precedes deteriorating WM integrity. ...

Evolution from the physical process-based approaches to machine learning approaches to predicting urban floods: a literature review

Author(s): Md Shike Bin Mazid Anik

Urban flooding has become a growing concern for many cities due to accelerating urbanisation, changing weather, and drainage system aging. Earlier studies of floods have taken primarily the traditional process-based approach to predicting urban floods, offering limited exploration of recent advancements in AI-driven, real-time, and community-integrated ap ...

Comparative Analysis of Preferences and Willingness to Pay for COVID-19 Vaccine Among Individuals With and Without Chronic Diseases: A Discrete Choice Experiment Approach

Author(s): Begum A; Uddin MA; Ahsan SM; Islam MA;

Background and aims: The rapid development and deployment of COVID-19 vaccines have been pivotal in the global battle against the pandemic. However, vaccine acceptance remains a critical determinant of their effectiveness. While numerous studies have explored factors influencing vaccine acceptance, there is a notable dearth of research regarding preferenc ...

Disentangled representation learning for multi-view clustering via von Mises-Fisher hyperspherical embedding

Author(s): Li Z; Luo Z; Bouguila N; Su W; Fan W;

Multi-view clustering has gained significant attention due to its ability to integrate data from diverse perspectives, frequently outperforming single-view approaches. However, existing methods often assume a Gaussian distribution within the latent embedding space, which can degrade performance when handling high-dimensional data or data with complex, non ...

Unintended consequences of measuring gestational weight gain: how to reduce weight stigma in perinatal care

Author(s): Alberga AS; Incollingo Rodriguez AC; Nagpal TS;

In this commentary, we discuss how the practice of measuring gestational weight gain may perpetuate weight stigma and resultant discrimination if not thoughtfully assessed. We offer suggestions to reduce the likelihood of weight stigma and discrimination in perinatal care settings.

Effect of a single dose of lorazepam on resting state functional connectivity in healthy adults

Author(s): Ferland MC; Wang R; Therrien-Blanchet JM; Remahi S; Côté S; Fréchette AJ; Dang-Vu TT; Liu H; Lepage JF; Théoret H;

Lorazepam is a fast-acting benzodiazepine that is widely used to manage anxiety symptoms through modulation of GABAergic activity. Despite being one of the most prescribed benzodiazepines, the effects of a single dose of lorazepam on brain functional connectivity at rest is not known. In this pla ...

Deformable detection transformers for domain adaptable ultrasound localization microscopy with robustness to point spread function variations

Author(s): Gharamaleki SK; Helfield B; Rivaz H;

Super-resolution imaging has emerged as a rapidly advancing field in diagnostic ultrasound. Ultrasound Localization Microscopy (ULM) achieves sub-wavelength precision in microvasculature imaging by tracking gas microbubbles (MBs) flowing through blood vessels. However, MB localization faces challenges due to dynamic point spread functions (PSFs) caused by ...
