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 ... -
Role of 3D-organization of the X-inactivation centre in imprinted X-chromosome inactivation
The connection between 3D-genome organization and genome regulation is one of the fundamental questions in modern biology. In a nucleus, the genome is organized through different layers of 3D-organization such as ... -
Packaging and Functionalization of Fiber Bragg Grating Sensors for Various Sensing Applications.
In our world, numerous sensors are found everywhere, making our lives simpler and more comfortable. Among these sensors, optical sensors have undergone expeditious development, providing good performance. In particular, ... -
New Dimension in Senescence: Unraveling Cellular Senescence in Three-Dimensional Scaffolds
Aging is a ubiquitous process that results in the progressive and irreversible loss of function. It is induced by accumulating damage caused by a variety of stressors, both internal and external. Although the advancement ... -
Resource-Aware State-Triggered Networked Control Systems
State-triggered control is a popular control method in the field of networked control systems owing to its advantage of efficient utilization of resources while simultaneously achieving control objectives. In this control ... -
A Two Step Optimal Decoding for PSK and Trellis Coded Modulation in Noisy Index Coding Problem
Index coding is a communication problem in which a server has a set of messages and wants to broadcast them to a set of receivers. Each receiver is interested in a single message, but some of the receivers may have some ... -
Harnessing Strained Systems: Arynes, Donor Acceptor Cyclopropanes, and Bicyclobutanes in Annulations, Multicomponent Couplings and Insertion Reactions
More than a century ago, the discovery of aryne intermediates proved to be a valuable addition to the toolkit of organic chemists, enabling the synthesis of a diverse range of molecules using these electrophilic ... -
