Development of small molecules targeting GPCRs (PAR2 and LPA1) for potential use in cancer diagnosis and therapy
(2025)Lung cancer continues to be the leading cause of cancer-related mortality for both men and women worldwide. Over the past two decades, advancements in prevention, screening, and treatment have contributed to reducing the ... -
Demethylation of sulfobutylated kraft lignin and its application as phenol-formaldehyde adhesives
(2025)The shift toward sustainable and eco-friendly adhesives has led to increased research into renewable alternatives for petroleum-derived components in phenol-formaldehyde (PF) resins. Lignin, a natural phenolic polymer, ... -
Integrating multi-omics data via latent space construction for breast and bladder cancer analysis
(2025)Cancer remains one of the most complex and heterogeneous diseases, driven by intricate interactions across genetic, epigenetic, and transcriptional landscapes. Accurately understanding and predicting tumor characteristics, ... -
Petrogenesis of the Sunday Lake Intrusion, Jacques Township, Ontario, Canada
(2025)The Sunday Lake Intrusion (SLI) is an early-phase (1109.0±1.3 Ma) mafic-ultramafic intrusion associated with the Midcontinent Rift System. It was emplaced along the Crock Lake Fault, a splay of the regional Quetico fault. ... -
Geochemistry and geochronology of the Shebandowan greenstone belt in the vicinity of the Moss Lake deposit, NW Ontario
(2025)This thesis presents a detailed investigation of the geology, geochemistry, and geochronology of the Archean Shebandowan Greenstone Belt (SGB) in the vicinity of the Moss Lake gold deposit in Northwestern Ontario. The ... -
Petrology and geochemistry of the Saddle North Cu-Au porphyry deposit, British Columbia, Canada.
(2025)The Saddle North porphyry Cu-Au deposit, northwestern British Columbia, Canada, is located in the Upper Triassic Stuhini Group and is associated with the Late Triassic to Early Jurassic Tatogga Suite intrusions. This study ... -
Improving performance of NOMA and RSMA systems with improper Gaussian signaling
(2025)With the new wave of beyond fifth generation (B5G) and sixth generation (6G) communication systems, there is a perpetual demand for more wireless services with higher data rates, lower latency, and greater connectivity. ... -
Cultivating pedagogy: exploring the influence of intentional time spent outdoors on pre-service and novice educators’ teaching practice and philosophy development
(2025)The objective of this study was to examine how intentional time spent outdoors impacts pre-service and novice educators’ teaching practice and the development of their teaching philosophy. Current literature surrounding ... -
A special case of the range of invariant problem for AF type actions of Z₂
(2025)Elliott and Su gave a classification of inductive Limit type Z2 actions on AF algebras using a K-theoretic invariant. In this paper, we consider the range of invariant problem, and give a sufficient condition for an ... -
Functionalized lignin derivatives for flame retardant, thermal insulation, and coating applications
(2025)Lignin, a highly branched and heterogeneous biopolymer composed of phenolic units, is a key structural component of plant cell walls, providing mechanical strength, water resistance, and protection against microbial ... -
Effect of lignin content on the performance grade and stability of asphalt binders used in Thunder Bay
(2025)The design roads relies solely on bitumen as a binding agent because it provides superior adhesive properties and waterproofing capabilities. The main source of bitumen production from crude oil oil refining results in ... -
Upward book embeddings of DAGs: constraint-based methods and embeddability analysis
(2025)The k-page upward book embedding (kUBE) problem is a fundamental challenge in graph theory with applications in circuit layout, scheduling, and hierarchical visualization. Despite its relevance, the problem—particularly ... -
Tools from above: evaluating drone-borne aerial remote sensing systems for archaeological site and feature identification
(2025)Archaeological investigations are rapidly changing due to developing digital technologies. They affect data collection, processing, interpretation, and analysis, but have spawned new approaches to archaeological ... -
Predator-prey interactions under thermal pressure
(2025)Ectotherms' ecological performance is directly linked to their thermal environment, many of which are warming due to climate change. If predator and prey thermal niches differ, warming may impact the intensity of ... -
A process design for the purification of carbon contaminated with Cu-Bi alloy from catalytic methane decomposition
