Synthesis, characterization and biological investigation of self-delivering and modified short interfering RNAs (siRNAs)
(2021-07-01)Aberrant gene expression is a hallmark of disease, so it is of great interest to develop targeted therapies that provide a means to regulate gene expression. The RNA interference pathway serves as a natural defense system ... -
Anodic alcohol fuel cell reactions at platinum active sites on doped metal oxide supports
(2022-12-01)Fuel cells produce electrical energy via chemical reactions, which take place on the carbon supported platinum catalyst (Pt/C). As attractive as these devices may seem, their practicality is often limited by the functionality ... -
A modular approach to image matting
(2022-11-01)Image matting is the art of creating an accurate alpha matte for the purpose of foreground separation in an image or video. Although there have been many methods which only require an input image, the best-performing image ... -
TCP congestion control using reinforcement learning
(2022-10-01)TCP, a transport layer protocol which ensures the reliable delivery of information on the network, is the basis of Internet connectivity, with 85% of the worlds Internet traffic being TCP based. TCP however, is slow to ... -
Calculating thermochemical equilibrium for multiphysics simulations of nuclear materials : development of yellowjacket gibbs energy minimiser
(2022-11-01)Nuclear fuels and structural materials are highly complex systems that are remarkably challenging to understand and model. Material behaviours are influenced by multiple physical phenomena such as mechanics, chemistry, ... -
A privacy preservation framework for smart connected toys
(2019-09-01)Advances within the toy industry and interconnectedness have resulted in the rapid and pervasive development of Smart Connected Toys (SCTs), built to aid children in learning, socialization, and development. A SCT is a ... -
Unified processing of natural language and relational data
(2022-09-01)This work outlines a method for performing natural language tasks as part of a relational framework. Utilizing features of PostgreSQL as a relational database and its extensibility to allow for word embedding without leaving ... -
The analysis of the entomological and chemical decomposition of human remains to ultimately assess the viability of the domestic pig as a substitute in forensic applications
(2022-09-01)Death investigations often rely on the minimum post mortem interval (minPMI) estimations provided by forensic entomologists. The models accepted by courts in Canada are not based on research involving humans but rather on ... -
MAVIDS: an intelligent intrusion detection system for autonomous unmanned aerial vehicles
(2021-07-01)Unmanned Aerial Vehicles (UAVs) face a large threat landscape, being used in numerous industries in hostile environments while relying on wireless communication. As attacks against UAVs increase, an intelligent Intrusion ... -
Investigation of KimiaNet's and DenseNet's deep features in lung cancer subtypes
(2020-12-01)Deep neural networks (DNN) have extended applications in the _eld of digital pathology. One of which is to act as feature extractors for content-based image retrieval (CBIR) systems. Therefore, it is necessary to investigate ... -
Forward and reverse genetic approaches to investigate cellulose biosynthesis in Physcomitrium patens
(2021-04-01)Cellulose biosynthesis is a common feature of land plants and involves multimeric complexes composed of cellulose synthase A (CESA) proteins and other structural proteins. The exact stoichiometry of CESA proteins and ... -
A heart rate and skin response module for adaptive difficulty in virtual reality
(2022-09-01)Virtual Reality (VR) is becoming an ubiquitous technology currently being in many areas as it offers simulated realistic environments suitable for training. Despite the advances in VR technology, one-size-fits solutions ... -
A nonlinear and nonlocal model for animal aggregation
(2022-09-01)An aggregation model is a kind of model used to show the dynamics of the distribution of the population of organisms. Mathematically, we can use a partial differential equation to model the density of an organism at different ... -
