A Multiscale Modeling Study of Iron Homeostasis in Mycrobacterium Tuberculosis
(2018-05-10)Mycobacterium tuberculosis (M.tb), the causative agent of tuberculosis (TB), has remained the largest killer among infectious diseases for over a century. The increasing emergence of drug resistant varieties such as the ... -
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ... -
Multiscaling in three-dimensional fluid turbulence
Fluid turbulence remains one of the most fascinating unsolved problems in Physics. Different aspects of it have attracted physicists and fluid dynamicists for decades. This thesis studies multiscaling of velocity structure ... -
Nanocrystalline Titania Based Dye Sensitized Solar Cells - Effect Of Electrodes And Electrolyte On The Performance
(2015-07-22)Dye-sensitized solar cells (DSC) have attracted considerable scientific and industrial interest during the past decade as an economically feasible alternative to conventional photovoltaic devices. DSCs have the potential ... -
Nanodevices of Graphene, Carbon Nanotubes and Flow Behaviour of Graphene Oxide Gel
(2018-05-09)In the last three decades carbon nanomaterials such as fullerenes, carbon nanotubes and graphene have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical ... -
Nanoscale spatial and temporal response of lipid membranes interacting with biomolecules and nanoparticles
The cell membrane is the first point of interaction whenever any external biomolecule or nanoparticle encounters a cell. Thus the nature of interactions between the cell membrane and various proteins, nanoparticles, and ... -
Nature Of Criticality, Structuring, And Phase Behavior Of Complex Fluids
(2009-03-04)This thesis is mainly concerned with some important properties of complex fluids, and how these properties are influenced by structures in the nano/mesoscopic scale. Short-range assembly of the constituent molecules results ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ... -
Nega-base computer arithemetic-theory and applications
This dissertation presents a detailed study of negative base number representation—the theory as well as the development of suitable algorithms for building the arithmetic unit of a digital computer. The idea of negative ... -
Neuronal Correlations And Real-Time Implementation Of Spatio-Temporal Patterns Of Cultured Hippocampal Neural Networks in vitro
(2011-01-19)The study of cultured neuronal networks has opened up avenues for understanding the ion channels, receptor molecules, and synaptic plasticity that may form the basis of learning and memory. The hippocampal neurons prepared ... -
New coarse grained molecular mechanics for proteins dynamics and Its application on dynamics-function correlation
Dynamics information of proteins can be used for many purposes, ranging from evolutionary studies to biophysical analysis and drug-design processes, etc. Long timescale and compact dynamics information are obtained from ... -
New Dispersive Techniques for Quantum Field Theories
Quantum field theory has been remarkably successful in describing interactions of elementary particles, particularly through perturbative methods. However, many important regimes — including strong coupling and quantum ... -
A New Method To Determine Optimal Time-Delays Between Switching Of Digital VLSI Circuits To Minimize Power Supply Noise
(2010-06-01)Power supply noise, which is the variation in the supply voltage across the on-die supply terminals of VLSI circuits, is a serious performance degrader in digital circuits and mixed analog-digital circuits. In digital VLSI ... -
New tools to constrain EFTs and CFTs
In this thesis, we develop new methods for the S matrix bootstrap in the context of 2-2 scattering amplitudes and four-point correlators in conformal field theories (CFTs). For 2-2 scattering in quantum field theories, ... -
