Oscillatory neuronal activity can be quantified to help diagnose states of health and disease in the brain. These activities change on a fast time scale of milliseconds, which can only be captured by direct measurement of the brains electromagnetic activity. This is accomplished utilizing MEG and EEG technology, which can measure non-invasively these fast changes on the scalp surface. Moreover, using MEG, these signals can be observed within the brain volume through a localization process.
The objective of the proposed research is to investigate novel solid-state materials that have potential for hydrogen storage applications in fuel cell electric vehicles. Of interest are materials that can store hydrogen at ambient conditions and low pressures, have high gravimetric and volumetric hydrogen capacities, and can be safely packed into a hydrogen storage tank for automotive use. The research will focus on assessing the feasibility of threedimensional structures consisting of two-dimensional layered nanomaterials such as graphene as viable media to store hydrogen.
Helicopter and snowcat skiing in the backcountry involves different hazards such as avalanches, tree wells or helicopter incidents, which can result in serious injuries or even death. While the risk associated with avalanche involvements is well understood, no systematic analyses have been conducted on the other risks.
Over 350,000 Canadians live in long-term care facilities where the rate of falls is up to 3 times higher than among individuals living in the community. Wearable sensor technology holds great promise to accurately monitor an individuals fall risk based on the activity profile and to detect dangerous fall events. With the understanding that hip protectors are commonly used in this population the objective of this project is to investigate the feasibility of a sensor-based hip protector to accurately detect falls and monitor daily activities.
Recent advances in applications of deep learning in natural language processing has provided potential opportunities in building robust information retrieval and conversational models that require far less hand-crafted features for understanding the intent of queries and ultimately building question-answering systems. In particular, there has been several advances in factoid question-answering systems and some recent attempts to moving beyond factoid questions.
A complex web of federal, provincial and municipal laws, regulations and policies affect the lives and the health of people who are homeless, use drugs, and/or engage in sex work. These populations also have high incidents or elevated risk of contracting HIV and/or HCV, as well as risk of overdose death. The goal of the project is to gather province-wide data on the role of legal systems in criminalizing, and increasing the risk to life, health and safety, of these populations, and in particular, increasing the risk of contracting HIV, HCV or overdose death.
The increased incidence of traumatic brain injury (TBI) and its potentially serious long-term consequences have enormous clinical, societal and economic impacts in Canada. Yet despite its relatively high prevalence, TBI is one of the least understood neurological injuries. Emerging evidence shows that the effects of TBI are not transient and may be associated with significant long-term consequences on brain function. An impact to the head results in an immediate and direct insult to the brain, setting off a complex cascade of metabolic and neurochemical events.
Steep creek hazards such as debris flows and debris floods pose a considerable risk to mountain communities and infrastructure. Relative to other geohazards, debris flows and debris floods are particularly hazardous because they travel rapidly, provide minimal warning and occur frequently. In Canada, professionals have little experience with debris-flow risk reduction due to limited development in mountainous areas. As mountain communities and infrastructure projects expand into more rugged terrain, there will be an increased demand for debris-flow and debris-flood protection in our country.
Kelp beds are marine sanctuaries, providing some of the most productive ecosystems on the planet and serving as critical habitat and refuge for many species, including juvenile salmon. Recently, declines in kelp populations have been reported by several groups including fisherman and kelp harvesters in the Pacific Northwest. However, the extent and cause of this habitat loss is unknown. It is thought that an increase in stressors associated with climate change (rising ocean temperatures or acidification) is a major contributor.
The complexity of movement and behaviour in Pacific herring (Clupea pallasii) stocks targeted by commercial and indigenous fisheries in BC is poorly understood and often discounted in fisheries management policies, possibly contributing to recent stock declines.
