Enantioselective cross-coupling of monosubstituted ferrocenes in chiral ionic liquids
(2024)Planarly chiral ferrocenes have applications in pharmaceuticals, agrochemicals, and biomedical research for their use as ligands or catalysts in asymmetric synthesis. Previous methods of enantioselective synthesis of ... -
The status of turtle populations in Point Pelee National Park: a 20 year update
(2024)Long-lived species such as turtles may appear to have healthy persistent populations if adults are consistently observed; however, study of size structures can reveal declining populations left vulnerable by limited ... -
Ground improvement of non-cohesive soil using nanoparticles, specifically, laponite
(2024)Ground improvement through densification is a widely used techniques to mitigate the risk of liquefaction and significant soil deformations. Traditional site stabilization techniques have certain limitations such as ... -
The design of fast-transient cap-less low-dropout voltage regulators
(2024)This thesis provides a theoretical and experimental study of cap-less LDO regulators for high speed applications. The three different architectures used in LDO designs are re- viewed in detail along with their advantages ... -
Symptoms of premenstrual dysphoric disorder and cycle phase are associated with enhanced facial emotion detection: An online cross-sectional study
(Sage, 2024)Background: Premenstrual dysphoric disorder is a depressive disorder affecting 5%–8% of people with menstrual cycles. Despite evidence that facial emotion detection is altered in depressive disorders, with enhanced detection ... -
Revolutionizing Women’s health: the quest for materials for next-generation, non-hormonal intrauterine devices
(Springer Nature, 2024)With over 200 million users worldwide, copper intrauterine devices (Cu-IUDs) are the world’s most popular, non-hormonal, long-acting, and reversible contraception method. Cu-IUDs cause uncomfortable side effects such as ... -
Short-term responsive mating intentions increase with estradiol and testosterone across the menstrual cycle: scale development and an observational study
(MDPI, 2024)The extent to which estradiol, progesterone, and testosterone influence mating behavior across the menstrual cycle is unclear. The Proactive and Responsive Mating Strategies Scales (PARMSS) were developed to separately ... -
Privacy-preserving EEG data frameworks for brain-computer interfaces
(2024)Non-invasive brain-computer interface (BCI) systems rely on brainwave activity, predomi- nantly captured through Electroencephalography (EEG), to facilitate seamless interactions with digital platforms. Throughout its ... -
Formation and nanoscale characterization of self-assembled molecular structures on Au(111) and Ag(111) surfaces
(2024)The growing interests in nanomaterials stem from remarkable properties arising from reduced dimensionality. On-surface synthesis utilizes surface/nanoscale science techniques to design and make nanomaterials through a ... -
Reliability analysis of slopes with truncated quantile functions from small, truncated/censored samples
(2024)Truncated and censored samples encountered in geotechnical engineering arise from various factors such as equipment limitations, formation characteristics, sample disturbance, unsuitable sampling methods, environmental ... -
Probabilistic reliability analysis of slopes with truncated random variables from censored samples
(2024)Probabilistic reliability analysis and design have been a research topic of intense interest in geotechnical engineering in recent decades due to the inherent uncertainty in soil property data obtained from field or ... -
Usability, quality, and factors influencing acceptance of a resilience app (JoyPopTM) among university students
(2024)Campus mental health (MH) services are struggling with increasing postsecondary student MH needs, and many students face barriers to MH care, which can have long-term negative impacts on their well-being. MH smartphone ... -
Design, synthesis, and evaluation of novel aurora kinase inhibitors for cancer diagnosis and therapy
(2024)Cancer is the second leading cause of death globally. Advances in cancer diagnosis and therapeutics plays a critical role in global health and a patient’s life. Aurora kinases, as mitotic kinases, regulate multiple mitotic ... -
Assessing the efficacy of magnetic susceptibility as an archaeological characterization tool within a Canadian subarctic context
(2024)This thesis addresses experimental investigation of magnetic susceptibility and the utility of the Terraplus KT-10 magnetic susceptibility meter to characterize subarctic archaeological deposits. The Hogarth Tree Farm, ... -
Evaluation of multi-angle imaging with planar organ-targeted positron emission tomography detectors
(2024)Positron Emission Tomography (PET) with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18F-FDG) is a functional imaging modality which is capable of detecting cancer tumors based on their increased metabolic activity – a ... -
Policies, procedures, and guidelines: are universities effectively ensuring AI (academic integrity) in the era of generative AI?
(2024)The objective of this study was to analyze Generative AI guidelines and policies at Canadian universities, examining how these universities are ensuring academic integrity in the face of challenges posed by using Generative ... -
An improved semi-supervised learning framework for Image semantic segmentation
(2024)Traditional supervised learning methods depend heavily on labeled data, which is both costly and time-intensive to acquire. Self-supervised learning approaches present a promising alternative to supervised learning, ... -
