Indumathi Prakash, a 21-year-old undergraduate student at Harvard University, is working remotely from home under the guidance of Dr. Robert Colautti, who heads a lab at Queen’s University devoted to the study of genetics and biological invasions. Prakash is helping to develop a first-of-its-kind device to quickly extract and purify DNA from ticks in the field as part of a project for rapid detection of pathogens using on-the-spot gene sequencing.
Integrated multi-trophic aquaculture (IMTA) is a technique by which the environmental impacts are minimized while efficiency is increased. However, these aquaculture activities can put a strain on their surrounding environment, as operations encroach on valuable wetland areas, act as a stressor on local water resources, and effluent waste can increase the concentrations of pollutants in nearby waterbodies. Hence, development IMTA system that can produce fish and marketable co-products without drastic water demands will improve operations.
The proposed research project is to design a microfluidic contact lens that will be used to track the fluctuations in intraocular pressure. Intraocular pressure is the primary factor to monitor the progression of glaucoma, which is a chronic disease that leads to permanent vision loss and currently has no cure, making early and frequent testing essential. By utilizing microfluidic channels embedded into a soft contact lens, the changes in corneal curvature can be captured and the intraocular pressure can be determined, as it is directly proportional.
Gallium nitride (GaN) high-electron-mobility transistors (HEMTs) are good candidates to replace the traditional silicon-based transistors. Although these devices show superior performances compared to Si and SiC-based devices, they suffer from some reliability issues. The aim of this research project is to improve the performance of the GaN HEMTs and enhance their reliability by performing a data analysis technique. This analysis would result in better understanding of GaN HEMTs’ characteristics.
Osteoarthritis (OA) is a common disease in middle-aged and older Canadians attending primary care practitioners. As the Canadian population ages and with increasing obesity, OA will become an increasing burden for individuals and the health care system. Given the potential of Electronic Medical Record (EMR) data for surveillance of the population that is at high risk of or is diagnosed with OA, we will apply text mining method to investigate this problem further.
Sea stacks are natural pillars of rock that are usually found on shorelines. They are fascinating formations that are popular destinations for geotourism, including at the Hopewell Rocks Provincial Park, New Brunswick and Flowerpot Island in Fathom Five Marine Park, Ontario. As they experience continuous wave and tidal erosion, sea stacks eventually collapse. Given their popularity, there is an elevated risk of injury or fatality to visitors that is managed by Parks by limiting access to sea stacks that are closer to collapse.
The proposed project investigates an approach to solve difficult physics problems, which are too computationally intensive for standard computers, using Xanadu’s near-term quantum computers. The goal of the project is to create a simulation tool that harnesses the exponential increase in efficiency offered by quantum computers to simulate the movement of particles and the subsequent emitted radiation at the nanometer scale. These simulations could have practical implications for experiments involving optical and laser physics and could lead to further insights concerning atomic behaviour.
The objective of the proposed internship is to help support the launch of disability inclusive content for an app created by ParticipACTION, Canada’s leading non-profit physical activity organization. The goal of the content is to motivate inactive Canadians with a disability to sit less and move more, with the aim of achieving Canada’s Physical Activity Guidelines.
The normal rhythmic beating of the heart is controlled by a set of electrical signals. When these signals are scrambled and the heart is no longer beating regularly, it produces a medical condition known as cardiac arrhythmia. There are several types of cardiac arrhythmias, the most common one being atrial fibrillation (AF) that affects more than 350,000 Canadians, which has far reaching impacts on the healthcare system and broader economy in the order of $3.6 billion/year.
Evidence has shown considerable individual variability in bacterial content of the gut microbiota, which is hypothesized to influence brain function. Research examining this relationship suggests that microbiota transplantation may aid in improving depression symptoms by recolonizing the gastrointestinal tract with healthy bacteria. The study will examine the effects of a microbial therapeutic composed of various strains of gut bacteria from a healthy donor on mood.
