Elucidating mechanisms regulating GC-C signalling in colorectal cancer
Colorectal cancer is the third most frequently diagnosed cancer and the second major cause of cancer death worldwide. Classical therapies for treating colorectal cancer are mostly nonspecific and, therefore, are associated ... -
Studies of Models of Superfluids from Nanometres to Astrophysical Scales
In this thesis, we study various models of superfluids applicable across a broad range of systems, from laboratory flows to astrophysical scales. At zero temperature, we utilize the Gross-Pitaevskii model of superfluid 4He ... -
Neuroimmune Regulation in Caenorhabditis elegans: The Roles of the Amphid Sensory Neurons and Olfaction in Host Immune Responses
The ability of hosts to rapidly sense invading pathogens and mount an appropriate response is paramount for host survival. Pathogens, pervasive in the natural world, present a perpetual threat to host organisms. Examining ... -
Synthesis, characterization and morphology control of colloidal MoS2 quantum dots and their applications
The quantum dots (QDs) are known as artificial atoms due to their size of the order of 2-10 nm. After their discovery in 1980, QDs have attracted significant attention due to their enhanced optical, electronic, and chemical ... -
Dynamics of a Suspended Microchannel Resonator
Micro-Electro-Mechanical-System (MEMS) mass sensing devices have a wide variety of applications in healthcare diagnostics and biosciences. Typically, mass sensing on a MEMS device works by physisorption and chemisorption ... -
Integrating magnetic swimmer with fluorescent color centers
Nitrogen vacancy (NV) centers in diamonds are of current interest as quantum sensors, single photon sources, and biological nano-materials due to their unique optical and spin properties, bio-compatibility, and robust ... -
Advancing the Communication Complexity Landscape of Perfectly Secure Multiparty Computation
Secure multiparty computation (MPC) allows n distrustful parties to jointly compute a function on their inputs while keeping their inputs private. The distrust is modelled as an adversary that controls up to t parties and ... -
Integration of Resonant Plasmonic Nanostructures with 2D Materials: Strategies and Applications beyond the Visible regime
Plasmonics deals with the interaction of incident electromagnetic waves with the free electron gas within metal nanostructures, enabling rapid signal processing and the confinement of light into subwavelength scales, leading ... -
Regulatory events governing host-C. albicans interaction: potential implications for wound healing
Regulatory events governing host-C. albicans interaction: potential implications for wound healing. Candida albicans is an opportunistic fungal pathogen that resides commensally in 50% of the world population and is known ... -
Explorations of singularities in some hydrodynamical partial differential equations
The global regularity problem for the 3D Euler equations remains unsolved. The presence of finite-time singularities (FTS) can signal the breakdown of the PDE as a physical model for fluid flow; it is also conjectured to ... -
Identifying novel molecular players involved in patterning the dorsal longitudinal muscles of Drosophila melanogaster
Pattern formation, a fundamental concept in developmental biology, describes how living systems organise complex structures from initially undifferentiated cells. This process, influenced by genetic information, underpins ... -
Development of Pulsed Power Systems and Tooling Coils for Electromagnetic Manufacturing Applications
Electromagnetic pulse manufacturing is an emerging non-conventional manufacturing technique used for the forming of workpieces at very high strain rates. The manufacturing assembly consists of the tooling coil (or actuator), ... -
Monte Carlo Simulations With Novel Sampling Variance Reduction Schemes For Structural Reliability Estimation
The work reported in this thesis is in the area of computational structural reliability modelling. The primary focus of the study is on the estimation of structural reliability using Monte Carlo simulations with sampling ... -
On the nature of transonic buffet in a finite span wing
Transonic buffet, or self-sustained shock oscillations caused by shock boundary layer interactions, creates lift and drag fluctuation on the wing of an aircraft. This aerodynamic instability limits the flight envelope of ... -
Studies of light-matter interaction in driven circuit quantum electrodynamics (cQED) systems
Quantum information processing leverages the principles of quantum mechanics to process information in ways that classical systems cannot. The principle of superposition and entanglement can allow quantum computers to solve ... -
Collaboration Models for Ride-hailing and Transit Service Providers to Facilitate First- and Last-mile Connectivity
Mobility-as-a-Service (MaaS) has gained significant popularity in the past few years. Various ride-hailing service providers (RSPs, e.g., Uber, Lyft, Didi, Ola, etc.) have entered the transportation market to provide this ... -
Targeting RNA with Drug-Like Small Molecules and Fluorescent Probes for Mapping Cell Fate
Part A Ribonucleic acid (RNA) plays a central role in various essential functions such as cellular information transfer and gene regulations in living organisms.1 Recent studies have shown that RNA is involved in various ... -
Zero-Knowledge Proofs with Enhanced Deniability
In cryptography, deniability is a crucial concept that allows a participant to plausibly deny taking part in executing a scheme or protocol. Non-interactive zero-knowledge (NIZK) proofs enable a party (the prover) to ... -
Learning Multiple Initial Conditions using Physics Informed Neural Networks
Physics-Informed Neural Networks (PINNs) and its variants have emerged as a tool for solving differential equations in the past few years. Although several variants of PINNs have been proposed, the majority of these ... -
