Ecology of the terrestrial carbon cycle: Influence of climate and animals
The terrestrial carbon (C) cycle involves fluxes between multiple pools that determine ecosystem functions and regulate global climate. These fluxes and pools are influenced by changes in abiotic (temperature, precipitation ... -
Characterization and Control of Boundary Layer Transition Caused by Distributed Surface Roughness
Distributed roughness occurs over a variety of aerodynamic surfaces such as wind-/gas-turbine blades and aircraft wings in the form of dust, insect strikes, fouling or icing. The disturbances introduced by the roughness ... -
Integrative multi-platform approach to identify biomarkers of diabetes-associated breast cancer progression
Breast cancer (BrC) is the leading cause of cancer-related death among women worldwide, including in India. Major risk factors for BrC include genetic predisposition, mutations in BRCA genes, post-menopausal hormonal ... -
Realization of magnetic Weyl semimetallic phase in pyrochlore iridates thin films
Weyl semimetals (WSMs) are characterized by two linear non-degenerate band crossing inside the bulk of the Brillouin zone. The spin-degeneracy of the bands can be lifted by either broken inversion symmetry or broken ... -
Decoding of Attention and Behavioral State Using Local Field Potentials
Visual attention has been shown to modulate perceptual behavior and neuronal activity. Early psychophysical studies on attention showed that the subjects detected a target presented at the attended location better (i.e., ... -
Characters of classical groups twisted by roots of unity
This thesis focuses on the study of specialized characters of irreducible polynomial representations of the complex classical Lie groups of types A, B, C and D. We study various specializations where the characters are ... -
Synthesis, Structure, White-light Emission, Sensing and Catalytic Studies on Metal-organic Framework (Mof) Compounds
Metal Organic Framework (MOF) compounds are now recognized as a distinctive area of research in the fields of chemistry, materials, and other related sciences. The MOF compounds offer many potential applications towards ... -
Algorithms for Investigating, Decoding and Designing ligand recognition sites in proteins - A Structural Bioinformatics Approach to Studying Protein Function
All physical processes in living organisms are driven by specific biomolecular interactions. Elucidating the characteristics of biomolecular interactions between proteins and their respective small molecule ligands can ... -
Understanding the role of DNAJC30 and ISCU in mitochondrial homeostasis
Williams-Beuren Syndrome (WBS) is a rare multisystem genomic disorder characterized by mild to moderate cognitive impairment, unique personality traits, distinctive facial features, cardiovascular problems, and infantile ... -
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ... -
On mechanisms and conformational dynamics of Drug:H+ Antiporters
Multidrug efflux is an active transport process involving energy consumption to drive antibacterial compounds out of cells. This is performed either through primary active transport, where chemical energy, such as hydrolysis ... -
Harmonic Map Heat Flow and Framed Surface-group Representations
This thesis concerns the construction of harmonic maps from certain non-compact surfaces into hyperbolic 3-space H3 with prescribed asymptotic behavior and has two parts. The focus of the first part is when the domain ... -
High-Throughput Bending Tests for Investigating Creep Behavior Affected by Structural and Microstructural Inhomogeneities
The bending of cantilevers is an alternate technique for the extraction of power-law creep parameters of materials. It has been shown earlier that in homogeneous systems showing tension-compression symmetry, digital image ... -
Investigation of machine learning and deep learning methodologies for applications in biomechanics, additive manufacturing, and microstructure fingerprinting: A Biomaterialomics approach
Traditional approaches to developing biomaterials and implants require intuitive tuning of process variables, long innovation cycle, and high costs. Accelerating the production of personalized, implantable biomaterials and ... -
Damping of magnetic-Coriolis waves with imposed magnetic field orthogonal to the axis of rotation
Small-scale columnar structures (<10 km radius) in Earth's outer core result from inertial waves. In highly conducting fluid, magnetic field behaviour resembles stretched elastic strings and transmits disturbances as Alfvén ... -
Privacy in Information Retrieval, Delivery and Distributed Computing
The aim of our work is to address the challenges of privacy in information retrieval, information delivery, and in distributed computing systems. We focus on reducing the download and upload costs and decreasing the ... -
Ground Displacements and Stresses around Single and Twin Tunnels using Analytical and Numerical Approaches
Significant emphasis is given nowadays on exploring underground space- in the form of tunnels- for (i) fast commuting in urban areas, (ii) connectivity to remote areas under different weather conditions, (iii) military ... -
Bioinspiration for battling bacteria: Nature inspired high aspect ratio nanostructures for new age antibacterial surfaces
Bacterial colonization and biofilm formation on abiotic surfaces effectuate corrosion, fermentation, and infection resulting in tremendous economic and human losses each year. Aggravating the situation, new multi-drug ... -
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ... -
Translation in the 3'Untranslated Region of Mammalian Transcripts
Mammalian mRNAs generally have a 5'UTR (untranslated region), a coding DNA sequence, and a 3'UTR. The 3'UTR of mRNA is generally believed to be the untranslated region of the mRNA. However, there are certain instances ...
