Syntheses and Structural Investigations of Iron(III) Ternary Complexes And Cu(II) Binary Complexes of Nucleotide and its Constituents
Nucleotide is the monomeric unit of DNA and RNA, being the building block of nucleic acid, it plays important roles in many biological processes. For example, Adenosine tri phosphate (ATP) acts as a storage and transporter ... -
Bandit Algorithms: Fairness, Welfare, and Applications in Causal Inference
We study regret in online learning from a welfarist perspective and explore an application of bandit algorithms in causal inference. We introduce Nash regret, which measures the difference between the optimal action ... -
An importance sampling in N Sphere Monte Carlo and its performance analysis for high dimensional integration
Statistical methods for estimating integrals are indispensable when the number of dimensions (parameters) become greater than ~ 10, where numerical methods are unviable in general. Well-known statistical methods like ... -
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ... -
Investigations into a novel process for high ash Indian coal gasification- a two-stage gasifier
India, in addressing climate change, has embarked on clean coal initiatives to reduce carbon emissions. Various measures are taken towards meeting the decarbonization process, and coal conversion through gasification is ... -
Investigating Neural Mechanisms of Word Learning and Speech Perception
Language learning and speech perception are remarkable feats performed by the human brain, involving complex neural mechanisms that allow us to understand and communicate with one another. Unravelling the mysteries of these ... -
Search for Long-Lived Particles at High Luminosity Large Hadron Collider and Beyond
Despite extensive searches, clear indications of new physics beyond the Standard Model (BSM) remain elusive. Traditionally, experimental searches at the Large Hadron Collider (LHC) during Phase I and phenomenological studies ... -
Solid Oxide Based Electrodes for CO2 Reduction
The conversion of CO2 to fuels can be instrumental in reducing future dependence on fossil fuels. High temperature (800oC) electrochemical reduction of CO2 to CO using a solid oxide electrolysis cell (SOEC) provides an ... -
Integrating Computational Tools and Models to Study Positive-sense RNA Virus Lifecycle
Positive-sense single-stranded RNA ((+)RNA) viruses pose significant challenges to public health. Notable families such as Enteroviridae, Flaviviridae, and Coronaviridae have caused epidemics (Dengue, Poliomyelitis, Zika) ... -
Topological Structures and Operators for Bivariate Data Visualization
Understanding complex phenomena in diverse scientific and engineering disciplines often relies on decoding the interplay among real-valued or scalar fields that are measured or computed over a spatial domain. This thesis ... -
Planar tunneling in twisted moire heterostructures
Quantum tunneling is a phenomenon that has excited physicists for many decades. With the ability to exfoliate two-dimensional (2D) materials from the bulk, including graphene, hexagonal boron nitride (hBN), and transition ... -
Single molecule based Super-Resolution Microscopy for disease biology
Advances in single-molecule imaging and super-resolution microscopy have revolutionized the field of cell biology, offering unprecedented insights into complex biological processes at the nanoscale. In this thesis, we ... -
Study of the Effect of Ag-Addition and Double Substitution (Te/Gd and Se) on the Thermoelectric Properties of Cu12Sb4S13 Tetrahedrite
Non-renewable energy sources, such as natural gas, coal, and oil, supply over 80% of the world’s energy demands. The earth’s atmosphere is heavily polluted with CO2 generated from fossil fuels and natural gases, raising ... -
Integrated Photonic Devices in Near-IR to Mid-IR for Agricultural and Environmental Sensing Applications
Near to mid infrared (NIR-MIR) chemical sensing is a remarkably influential analytical technique that capitalizes on the interaction between matter and infrared radiation within a specific wavelength range. Predominantly ... -
Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ... -
Single Molecule Based Spatio-temporal Super-resolution Microscopy for Visualizing Single Molecule Dynamics in Cellular System
Over the last decade, single-molecule localization microscopy (SMLM) has developed into a set of powerful techniques that have improved spatial resolution over diffraction-limited microscopy and demonstrated the ability ... -
Reduced Electrolytic Capacitor Based Single-Phase Converters: Topologies, Control, and Stability
Single-phase converters (SPC) find wide applications in different domestic and industrial appliances, ranging from a few hundred Watts to a few Megawatts. Second-harmonic ripple filtering is a critical issue in SPCs, for ... -
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
