Caractérisation de micro-commutateurs MEMS pour des applications cryogéniques et quantique

Dans le cadre d’un projet de recherche, des micro-commutateurs MEMS ont été fabriqués sur une ligne de prototypage industrielle 200 mm. Ces dispositifs millimétriques sont compacts et consomment très peu d’énergie, ce qui les rend particulièrement intéressants pour des environnements cryogéniques nécessitant une dissipation de chaleur minimale. Ce projet vise à évaluer les performance et […]

Associations between sleep disturbances and cognitive performance in Parkinson’s disease: a multimodal neuroimaging study

This project aims to explore the association between sleep disturbances and cognitive function in Parkinson’s disease (PD) through multimodal neuroimaging. Sleep issues, including insomnia, excessive daytime sleepiness, and rapid eye movement sleep behavior disorder, affect a significant portion of PD patients and are linked to cognitive impairments. This project will investigate how these sleep disturbances […]

Personnalisation des prothèses unicompartimentales du genou : Estimation des contraintes articulaires durant diverses tâches de la vie quotidienne

Ce projet vise à évaluer l’efficacité fonctionnelle des prothèses unicompartimentales personnalisées (PUCP) pour le genou, en comparant leurs performances à celles des prothèses standard (PUC). À partir de l’analyse biomécanique de diverses tâches fonctionnelles (marche, montée d’escalier, squat et lever de chaise) de 22 patients opérés (avec PUCP et standards) et 22 participants sains, des […]

Metabolic control of reproductive maturation

There is a critical period during late gestation in humans and perinatally in atricial animals like rats and mice , during which the building blocks of energy homeostasis, including the hypothalamic regulation of food intake and energy balance become established. During this early postnatal period, neuronal dendritic and axonal elongation as well as pruning takes […]

Production of cellulose-based membranes with nanoadditions for air filtration

Global warming is one of the most pressing challenges of our time. Greenhouse gases like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) trap heat, causing the planet’s temperatures to rise. Currently, the challenge is to achieve systems that solve problems such as environmental pollution through the design of green products and sustainable processes. […]

Dietary protein impact on post-prandial hepatic metabolic fluxes.

Obesity and type 2 diabetes (T2D) affect millions of people worldwide. When considering dietary strategies to offset T2D, the focus has been mainly to reduce amounts and specific types of fat and carbohydrates, with very little consideration given to protein sources. Earlier studies done by the applicant and colleagues showed that dietary protein composition influences […]

Use of platinum nanoparticles to enhance the sensitivity of microfluidic diagnostic tests

Rapid diagnostic tests play a crucial role in preventative medicine and epidemiology. Despite their widespread adoption in the industry, obtaining precise, quantitative results for low concentrations of analyte remains a significant challenge. For example, point-of-care (POC) tests for COVID-19 can exhibit a 70% rate of false negatives in some cases. The aim of this project […]

Étude de plasmas à onde de surface par spectroscopie d’émission

Le projet de recherche de Téo Clergereaux dans le groupe du Pr Luc Stafford au département de physique de l’université de Montréal vise à étudier le fonctionnement d’un plasma lors d’une injection pulsée de gaz. Cette étude reposera sur des mesures de spectroscopie d’émission optiques temporelles. Cette étude s’intègre dans un projet beaucoup plus large […]

Data collection and cross-domain representation models for trajectory analysis

Due to the vast amount of available tracking sensors in recent years, high-frequency and high-volume streams of data are generated every day. Such tracking sensors include but are not limited to vessel, airplane or vehicle tracking data, drones, smartwatches and smart bands as well as cameras and earth observation sensors. Despite the overabundance of data […]

Biais de publication des études examinant les risques associés aux médicaments pris pendant la grossesse

Devant le nombre grandissant d’études sur l’effet des médicaments pris pendant la grossesse, les chercheurs et cliniciens sont confrontés à une multitude de résultats, parfois contradictoires. Les méta-analyses peuvent aider à évaluer la qualité et à synthétiser ces études. Les résultats des méta-analyses peuvent toutefois être biaisés par le biais de publication, qui survient lorsque […]

Improving Differentially Private Deep Learning Models

Machine Learning (ML) models are known to leak information about the data they were trained on, enabling membership and reconstruction attacks [7]. Such privacy risks damage trust in ML, and hinder the broad adoption of model co-training, through Federated Learning or cloud-based co-training. This is especially true in sensitive domains that could significantly benefit from […]
