Distributed Memory Management for Fast Data

High-volume online stream processing, also known as fast data processing, is becoming increasingly important in a number of different commercial sectors. Unlike big data processing in which data is processed asynchronously in batches, fast data processing performs synchronous data analysis that generates actionable results within a specified deadline. One of the key challenges in building a fast data processing system is in scaling with increasing volumes of data. In our proposed research, we plan to build a system to efficiently manage the available memory across the entire deployment. The system will determine which data blocks should remain in memory, where a data block should be placed, and what fault tolerance strategy the system should employ. The objective is to build a scalable processing system that can handle both current and future fast data processing demands. TO BE CONT’D

Investigations phytochimiques de la flore nordique du Québec : isolation de produits naturels bioactifs et d’ingrédients actifs

Les végétaux produisent une variété de molécules bioactives en réponse à un stimulus externe (intensité lumineuse, prédation, pathogènes, conditions climatiques, etc.). Ainsi, nous croyons que la flore nordique du Québec regorge de substances bioactives inédites étant donné qu’elle subit des stress environnementaux qui sont uniques au monde. L’identification de nouveaux produits naturels bioactifs issus de la flore nordique contribuera à illustrer l’impact de la nordicité sur la composition moléculaire des végétaux du Grand Nord du Québec. De plus, la réalisation de ce projet conduira à une collection de produits naturels purifiés qui pourront être utilisée par les industries pharmaceutiques, cosméceutiques et nutraceutiques respectivement pour le développement de médicaments, de produits de beauté et de soins de santé. En étant partenaire industriel, la compagnie SiliCycle pourra développer une expertise en isolation de composés à haute valeur ajoutée qui sont destinés aux industries pharmaceutique, cosméceutique et nutraceutique.

Méthodologie d’analyse numérique de composite à renfort tridimensionnel

Les composites à renfort tridimensionnel sont de plus en plus utilisés dans l’industrie pour la fabrication de pièces à géométrie très complexe. Malgré l’avantage certain des composites 3D sur les laminés, son implémentation reste toutefois très complexe étant donné le peu de connaissances actuelles sur le comportement mécanique de tels matériaux. En effet, la méthode textile utilisée pour fabriquer la préforme influence grandement les propriétés mécaniques du produit final. De plus, divers phénomènes physiques interviennent lors de la fabrication d’un matériau composite en fonction du procédé utilisé. Ainsi, le développement d’une méthode d’analyse numérique se basant sur une géométrie de renforts 3D réelle va permettre de prédire efficacement les propriétés mécaniques des pièces produites à l’aide de ses renforts et améliorer le temps de modélisation des pièces futures utilisant les mêmes paramètres.

Investigation of Proteomic Changes Following Chilling Exposure in Resistant and Sensitive Zea Mays

A plants’ ability to withstand chilling and frost damage will dictate the geography in which production can occur. Global warming is predicted to increase chilling and frost injury in crops. It is important to note that frost injury is one of the key factors limiting production. In corn, chilling injury is an ongoing constraint for global production and expansion which affects food, feed and fuel supplies. Corn is an important model system as it is the largest crop, on a tonnage basis, produced in the world. The project is focused around developing a predictive model to find types of corn that will perform well under cold conditions. The desired outcome of the exchange is to incorporate important information on the protein contribution to the model, which would improve its predictive power and making it more versatile for a variety of academic and industry applications.

Assessing and improving the analysis of bird migration count data for population monitoring

Counts of birds passing a geographic location during migration to or from their breeding grounds are often used to estimate long-term population change. However, birds often stop at count sites for several days to fatten for their next migratory flight, affecting probability of detection. The migratory path followed might also vary among years. The influence of such factors on population estimates are unknown. We will use simulated migration count data to test the influence of birds stopping at a site and of variation in migratory route among years on our ability to estimate population size and change. We will also assess whether population estimates can be improved by alternative sampling or analysis techniques that mitigate the effects of stopover or shifts in migration route – for example, by combining data from multiple sites to better distinguish real population change from variation in counts from alternative factors.

Constraining exotic sources of electroweak symmetry breaking

The proposed research seeks to examine and constrain possible theoretical extensions of the Standard Model of particle physics (SM). The SM is a theory which successfully describes almost all known particle interactions. With the discovery of the Higgs boson, which is responsible for the mass of elementary particles via electroweak symmetry breaking (EWSB), all the major pieces of the SM have been experimentally verified. However, there are many indications that the SM is incomplete. One possible area of the SM that could be extended is the process of EWSB. Instead of the single Higgs boson of the SM being the sole source, there could be new exotic sources of EWSB. The goal of this research is to take the simplest model that adds exotic EWSB to the SM and relate its parameters to measurable experimental quantities and processes. Experimental data can then be used to constrain the allowed values of these parameters. These constraints will initially show where new physics could be expected to be found, and if no new physics is discovered the results can be used to rule out the possibility of exotic EWSB.

Nsyilxcn Revitalization and Documentation (Year 2)

The Nsyilxcn (Syilx Okanagan Interior Salish) language is critically endangered; fewer than fifty Elder speakers remain, no young people are learning at home and no effective school programs. Syilx people are highly invested in creating language opportunities, including teaching positions in schools, daycares, and adult programs, however no young speakers exist to staff them. Questions arise: how can we make Nsyilxcn language transmission more effective? What are the barriers to success, including linguistic, methodological, organizational, and community capacity challenges? The Syilx Language House Association endeavors to train Syilx youth to become language speakers, using cutting edge acquisition techniques. This research project is a second-year continuation of the lead researcher’s PhD and post-doctorate research in which five low-intermediate speakers were created through an intensive “Language House” model. This field is of great interest to First Nations Education, applied linguistics, as well as deeply valuable to First Nation community.

Proteome analysis of field versus chamber acclimated winter wheat and rye crowns

The most critical region for winter wheat (Triticum aestivum L.) winter survival is the crown. Exposure to different environmental cues during cold acclimation improves the crown’s resistance to freezing. This key fact is not taken into account in the design of controlled environment experiments and may not reflect actual mechanisms of cold hardiness in the field. Acclimation to multiple environmental cues under fall field conditions could explain the improved freezing survival of field as opposed to chamber acclimated plants. It is hypothesized that in field acclimated, greater accumulation of anti-freeze and dehydrin proteins in the crown’s vascular tissues improve resistance to freezing. The expected outcome of this study is to identify specific protein markers associated with enhanced freezing resistance in the current superior freeze resistant winter wheat ‘Norstar’ and more winter hardy ‘Puma’ rye. Identification of biochemical markers associated with field acclimation will be useful to breeders’ intent on improving winter hardiness in winter wheat.

Neuromorphic Computing with Stochastic Binary Weights Based on Magnetic Tunnel Junctions

Many problems which are best solved by neural networks are exhibiting rapid growth in nascent and existing fields, such as natural language processing, and image recognition for self-driving cars. Current limitations in manufacturing technologies impose limits that prevent these performance demands from being met through conventional methods. Neuromorphic computing has been proposed as a potential solution for problems best solved with artificial neural networks. The memory bandwidth intensiveness of neuromorphic computing architectures gives rise to power and performance constraints, which limit scalability. Attempts in weight quantization have been made to overcome this limitation, yet even in the case of single-bit binary weights, stochastic behaviour is required to achieve adequate performance; this is turn necessitates additional circuitry, negating the cost and performance advantages of binary weights. However, the emerging technology of Magnetic Tunnel Junctions is proposed as a method to implement inherently stochastic non-volatile Logic-in-Memory in binary weighted neuromorphic computing architectures.

The Odd Couple: Cancer and the Circadian Clock

Circadian rhythms are processes which allows animals to regulate their physiology based on time of day. These rhythms are controlled by the circadian clock, a group of transcription factors that form a feedback loop. Over 40% of the genome is transcribed rhythmically, implicating the clock in many physiological processes.
The cell cycle is another process which takes ~24h to complete in mammals. This is due to several checkpoints which are present to prevent the cell from precocious progression leading to DNA damage. The clock and the cell cycle have been proposed to be linked but this remains controversial. Unregulated passage through cell cycle checkpoints can lead to cancer formation. The proposed research will use the CRISPR/Cas9 genome editing technique to observe the potential link between the clock and the cell cycle in intestinal organoids. This research may allow for the development of novel targets in cancer therapies.

Modeling of thermoplastic pultrusion

Pultrusion is a manufacturing technique allowing to produce constant cross section beams of fiber reinforced plastics. The main challenge of pultruding thermoplastic composite is to impregnate the fiber bed with the high viscosity thermoplastic matrix. The goal of this research project is to use two existing models to model the pultrusion of thermoplastic composites. Mainly to correlate the processing parameters to the impregnation quality of the composite. This model could be used as a design tool for future pultrusion installations or used to reduce the amount of experiments necessary to produce good quality parts. At the end of this research project, a model of the pultrusion would be adapted to the pultrusion system present at Professor Nakai laboratory, and numerical results will be supported by experimental results to validate the model.

Crystal Orientation-Wetting Property Relationships for Cerium Oxide

Improving the durability of superhydrophobic surfaces is of significant interest in the surface engineering community. We have recently developed a novel superhydrophobic coating with a hard nanocrystalline nickel matrix and embedded hydrophobic polytetrafluoroethylene (PTFE) particles. To further improve the mechanical robustness of the non-wetting coating, the soft polymeric PTFE particles were replaced with hard, hydrophobic cerium oxide ceramic particles. However, the intrinsic hydrophobic properties of cerium oxide are not well understood. In the proposed research project, single crystal cerium oxide films with different crystallographic orientations will be produced by a pulsed laser deposition process and the wetting properties will be evaluated. Since the arrangement of cerium and oxygen atoms on the surface differs with orientation, we hypothesize that the wetting properties of cerium oxide surfaces vary with orientation. By understanding orientation effects on wetting properties, we can expect to be able to better engineer a durable superhydrophobic surface.
