Efficient Signal Processing and Radio Resource Management for High-Throughput and Low-Latency Massive MIMO Cellular Systems – Year two

Future cellular systems must accommodate increasing demand for very high throughput and low latency data services.
Massive multiple-input multiple-output (MIMO) approach involving base stations equipped with much larger numbers
of antennas than the numbers of users served promises to significantly increase network capacity, while nonorthogonal
multi-carrier transmission is expected to dramatically reduce the latency. Integration of these techniques
will require novel efficient transceiver signal processing and radio resource management solutions, such as reducedcomplexity precoding and user scheduling algorithms. These algorithms will need to be robust to typical
imperfections, such as antenna coupling in large arrays of limited physical size and also possible non-reciprocity of
uplink and downlink hardware chains, resulting in inaccurate channel state information at transmitters and reduced
capacity. 3D beamforming in massive MIMO will also be investigated. TELUS Communications has expressed great
interest in the proposed work and will support it in the amount of $30k per year.

Validation of wearable device for use in predicting high and low levels of stress and anxiety in daily life

The project explores the application of physiological sensors in psychology, mental health, and mindfulness by integrating artificial intelligence for emotional classification. It aims to validate a wearable physiological monitoring system, using devices like Fitbit Versa 6 and Emotibit, to predict stress and anxiety levels through machine learning. This initiative is crucial given the prevalence of mental health issues in Canada, affecting 20% of Canadians annually, and demonstrating a desperate need for effective solutions.
By understanding emotional states and external influencing factors, the project seeks to improve mental health monitoring. Wearable technology can capture physiological signals—heart rate variability (HRV), heart rate (HR), skin conductance, and blood oxygenation—that correlate with emotional changes. Numerous studies have linked HRV to mental health conditions like anxiety and depression, establishing it as a reliable measure of the autonomic nervous system’s response to stress.

Emma Lake Environmental Research and Stewardship Internship

Emma Lake is one of many recreational lakes located in the boreal forest of west central Saskatchewan that has experienced increased cultural eutrophication due to increased lake development and urbanization. Cultural eutrophication refers to artificially enhanced nutrient loading associated with shoreline development, vegetation removal, and factors related to sedimentation, increased use of fertilizers, and proliferation of septic pump-out systems. Concern for the lake environment has been steadily increasing as the lake experiences increased algal and weed growth, reduced water clarity, and diminishing environmental quality. The objective of this research is to identify metrics that are relatable and indicative of aquatic ecosystem health especially as it pertains to cultural eutrophication.

Automated gated quantum-dot 3D model generation and tuning for technology-computer aided design of realistic spin-qubit systems

Spin qubits—nanoscale quantum bits made in semiconductor materials—are a promising technology for building future quantum computers. They are highly miniaturized, can work at relatively higher temperatures than competing technologies, and can be made using standard industrial semiconductor-chip fabrication techniques, which makes them ideal for scaling up. However, traditional chip design software is not adequate for these devices because they operate under extremely low-temperature conditions and follow quantum physics rules.

To solve this, Nanoacademic created QTCAD®, the first commercial software designed to simulate spin qubits. QTCAD® is already used by researchers and engineers around the world. As devices get more complex, users need more automation to save time. This internship project will develop tools that automatically create 3D models of devices from simpler 2D designs and tune settings to get the desired performance—tasks that currently take a lot of manual work.

The intern’s work will become part of QTCAD®, helping users work more efficiently and supporting Nanoacademic’s efforts to provide tools and training for both academic and industry partners. These improvements will not only benefit users but also support Nanoacademic’s services, such as contract research and training in quantum technology programs worldwide.

Forecasting Levodopa-Induced Dyskinesia in Human Subjects with Parkinson’s Disease

We have developed a novel data augmentation procedure that significantly enhances machine learning-based classification of different brain imaging scans. Having successfully demonstrated proof-of-concept in a rodent model, we are now expanding this approach to clinical applications in humans. Specifically, we aim to utilize this technology to identify early biomarkers of neurodegenerative diseases, enabling personalized treatment strategies based on individual disease progression rates.

As a starting point, we will focus on Parkinson’s disease, which affects approximately 100,000 Canadians and is the second most prevalent neurodegenerative disorder. Over half of patients develop levodopa-induced dyskinesia, a challenging motor side effect. Our previous research demonstrated that individuals who develop this side effect exhibit distinct brain activity patterns from those who do not—even on the first day of levodopa treatment.

With our advanced machine learning technology, we believe we can accurately identify “at-risk” patients before symptoms manifest. This capability will provide clinicians with a powerful tool to tailor treatment strategies, mitigate dyskinesia risk, and uncover novel therapeutic targets. Ultimately, this project aims to establish imaging-based classification as a clinically viable approach for early-stage disease detection and personalized intervention.

Medical Microrobots for Anti-cancer Drug Delivery

This project focuses on developing innovative, biocompatible microrobots for targeted drug delivery, particularly in cancer treatment. By integrating smart hydrogels with magneto-active properties, these tiny robots can navigate the body and deliver highly precise chemotherapy drugs, reducing side effects and improving patient outcomes. Advanced 3D microfabrication techniques, such as two-photon lithography and digital light processing, will be used to create these microrobots, while external stimuli like radiofrequency (RF) fields and infrared (IR) illumination will control their movement and drug release. The collaboration between institutions provides access to cutting-edge equipment and expertise, ensuring that these microrobots are effectively designed, fabricated, and tested. This research has the potential to revolutionize targeted therapy, making cancer treatment more effective and less invasive.

Evaluating Mutational Signatures from Circulating Tumor DNA: A Comparative Analysis with Whole-Genome Sequencing

Cancer leaves behind unique mutation patterns, known as mutational signatures, which provide insights into its origins and potential treatments. Traditionally, these signatures are identified using tumor tissue samples, but obtaining biopsies can be invasive and challenging. A promising alternative is circulating tumor DNA (ctDNA)—small fragments of tumor DNA found in the blood. Liquid biopsies offer a less invasive way to study cancer mutations, but it remains unclear whether they capture the same mutational signatures as traditional tissue sequencing.

This project aims to compare mutational signatures derived from ctDNA and whole-genome sequencing of tumor tissue to assess their concordance. By analyzing data from both sources, we will determine whether ctDNA can reliably replace tissue biopsies for mutational signature analysis. If successful, this approach could improve non-invasive cancer detection and monitoring, reducing the need for surgical biopsies. The findings may also enhance computational tools for analyzing ctDNA, making cancer diagnostics more accessible and precise. Ultimately, this research brings us closer to personalized and less invasive cancer care, using simple blood tests to decode tumor biology.
