Insights into life-cycle stage transition of Trichomonas vaginalis and advancement in its diagnosis
Trichomonas vaginalis is a protozoan parasite and the causative agent of the most common non-viral, sexually transmitted disease (STD) in humans known as trichomoniasis. WHO estimates more than 270 million cases of ... -
Capacity Computation and Coding for Input-Constrained Channels
The setting of the transmission of information over noisy, binary-input, memoryless channels is today well-understood, owing to the work of several information theorists, beginning with Claude Shannon. It is known that it ... -
Optical and Electrical Studies of Hybrid Nanomaterial Composites Based on Noble Metal Nanostructures
Localized surface plasmon resonance (LSPR) in noble metal nanoparticles like gold (Au) and silver (Ag) results in enhancements in optical absorption and scattering by the nanoparticles, accompanied by a dramatic ... -
Experimental and numerical study of mechanics and mechanisms of mode I fracture of a textured magnesium alloy
In recent years, magnesium alloys have gained increasing application in the automotive industry to achieve weight reduction in vehicle components which is crucial for enhancing fuel efficiency and meeting stringent emission ... -
Collective Phototaxis of Chlamydomonas reinhardtii Cells
Microorganisms are omnipresent in our life and the environment, such as microbes in the gut, spermatozoa in reproductive organs, algae and protozoa in the aquatic ecosystem, and bacterial colonization and infection. ... -
Understanding the interplay between immune response and virus evolution
RNA viruses are the underlying cause of many human diseases, including the common cold, influenza, dengue fever, and COVID-19. Their ability to evolve rapidly makes them challenging to tackle, resulting in public health ... -
Molecular Approaches and Structural Insights into Correlated Triplet Pair Dynamics in Intramolecular Singlet Fission
Singlet Fission (SF) is a bichromophoric process whereby a singlet exciton is converted to two triplet excitons through an overall spin-conserved process. The last decade has seen an upsurge in SF research driven by its ... -
Studies on Metal Hydride Based Multifunctional Coupled Thermal Battery Systems
Thermal energy storage systems (TESS) based on chemisorption/thermochemical reactions have several advantages over conventional thermal storage systems based on sensible and latent heat. The advantages include high energy ... -
Atto-second Dynamics in Molecular Systems
The thesis describes the attosecond dynamics of small molecular systems, focusing on ionization delay times and hole migration delay times. These time delays are some of the fastest events in electronic dynamics. When an ... -
Machine learning and density functional theory assisted insights into the mechanical and oxidation properties of nickel-based superalloys
Due to global warming and increasing fuel costs, there is a constant thrust toward increasing fuel efficiency and reducing the emissions of gas-turbine engines, which are made out of superalloys. New superalloy materials, ... -

Tropical Teleconnections to the Indian Summer Monsoon in Observations and in a Coupled Model
An accurate seasonal prediction of Indian summer monsoon rainfall (ISMR) holds immense importance for the socio-economic well-being of South-Asian countries, as it directly impacts agricultural output and overall economies. ... -
Response of Granular Materials Towards Blast Loading
Granular media, such as sand, soil, and rocks, are commonly encountered in various engineering and geotechnical applications, and their response to blast loading is of significant interest. In this master’s thesis, the ... -
On commuting isometries and commuting isometric semigroups
This thesis consists of two parts- commuting isometries and commuting isometric semigroups. In the first part, we study the Taylor joint spectrum for a pair of commuting isometries in certain cases. We show that the joint ... -
Electron Microscopy Investigations of Surface-modulated Nanomaterials for Electrocatalytic Applications
With advancement and increasing usage of technologies, the demand for energy is also growing. However, the limited and ever-depleting stock of natural gas and fossil fuels has necessitated for better solutions in energy ... -
Exploring End-of-Life Photovoltaic (PV) Panel as a Building Material: A Case of Crystalline Silicon PV
The renewable energy share in the energy mix worldwide is rising sharply to mitigate climate change, with Solar Photovoltaics (PV) carrying a large share of 3.6%. However, the end-of-life (EoL) management of decommissioned ... -
Multimodal sleep staging and diagnosis of sleep disorders
Sleep is not a single uniform state, but rather a cyclical pattern involving multiple stages such as rapid eye movement (REM) and non-REM (NREM stages N1, N2, and N3). Polysomnography (PSG) is considered as the gold standard ... -
Computational study of membrane driven secondary structural changes in proteins
Conformational changes in proteins, the most abundant biomolecule found in all living organisms, are ubiquitous and triggered by several factors essential for protein function. Protein conformational changes typically occur ... -
