Immune cell surveillance and death on silicone catheter surfaces drives bacterial biofilm formation
Silicone venous catheters are among the most used medical devices in the world with a prevalence of up to 80% in hospitalised patients. While they are used for several life-saving applications, they are also prone to ... -
Identifying and Disentangling Different Sources of Variability in Travel Choice Models
Random utility maximization (RUM)-based discrete choice models are widely used for analyzing individual choice behaviour across diverse fields, including transportation, economics, market research, healthcare, and environmental ... -
Some investigations into the methods and applications of modern Feynman Integral evaluation
Feynman Integrals appear in perturbative quantum field theories and have been the focus of intensive study for over half a century. With the rise of the Standard Model of particle physics and its various extensions and the ... -
Investigation of the oxyfuel fluidized bed combustion characteristics of high ash Indian coal
Coal continues to be an important source of energy in developing countries like India. However, Indian coal has high ash content, which causes it to have high burnout time and, hence, lower combustion efficiency in ... -
Iridium-Catalyzed Enantioselective Alkylation of Enols and Their Surrogates
This thesis, entitled “Iridium-Catalyzed Enantioselective Alkylation of Enols and their Surrogates” is divided into four chapters. In Chapter 1, the examples of the utilization of vinyl azide as amide and ketone enolate ... -
Assimilation of near-surface soil temperature and soil moisture in an unsaturated flow model: State and parameter estimation using synthetic and field experiments
Soil moisture is a key variable governing land surface hydrology, agricultural productivity, and climate dynamics, influencing crucial processes such as evapotranspiration, infiltration, and surface runoff. Accurate ... -
Development of Inorganic Perovskite Nanocrystals for Optoelectronic Applications
Metal Halide Perovskites (APbX3) have garnered appreciable attention from researchers because of their fascinating optoelectronic properties. These properties include high absorption coefficient, defect tolerance, long ... -
Insights on the Evaporation and Precipitation of Pathogen-Laden Respiratory Droplets on Inanimate Surfaces
Disease transmission via fluid ejections from infected individuals is a critical public health concern, particularly in high-risk environments like hospitals, public transport, restaurants, and schools. Respiratory droplets ... -
Investigations on Pulse Width Modulation Techniques for Split-Phase Induction Motor Drives
A split-phase induction motor (SPIM) has two sets of identical three-phase windings. These two sets of windings are separated by 30◦ in space, which are, typically fed by a three-phase voltage source inverter (VSI) each. ... -
Semi-analytical solution for eigenvalue problems of lattice models with boundary conditions
Closed-form relations for limiting eigenvalues of an infinite k-periodic spatial lattice in any number of dimensions d, and its semi-analytical extensions for any given size n of the lattice with free-free boundary ... -
Application of Finite Element Limit Analysis and Other Means to Deal with Problems Involving Foundations and Excavations
The finite elements limit analysis (FELA) is an important tool to solve any stability problem in geomechanics. This method provides lower and upper bounds on the true solution for a material following an associated flow ... -
Understanding the Mechanism and Stereoselectivity of Fe-catalyzed Carbene Insertion Reactions using Computational Tools
Transition-metal and enzyme-catalyzed carbene insertion reactions are key methods for constructing C–X (X=N, O, S) and C–C bonds, primarily using catalysts such as Rh, Pd, Au, Cu, and Fe. While most of these give high ... -
Probing Electronic States in Twisted Bilayer Graphene with Electric Fields: A study of Superconductivity, Non-Local Resistance, Magnetoresistance Hysteresis, and Thermoelectric Effects
Introducing a `twist' degree of freedom to modify the low energy band structures and engineer novel electronic phases from the constituent van der Waals 2D materials, was proposed theoretically more than a decade earlier ... -
Investigation of Consolidation Methods for Developing Load-bearing Structures from Lunar and Martian Regolith Simulants
Lunar and martian surfaces provide ideal candidates for establishing extra-terrestrial human settlements, given their proximity to the earth and potential for harbouring water. Significant recent research has focused on ... -
