Recent years have witnessed a significant rise in the footprint of electronics in variety of fields like healthcare, energy harvesting, human computer interaction etc., due to the discovery of new materials and better ... -
Investigation of the stress-induced translatome of matrix-deprived cancer cells
Cancer remains one of the leading causes of death worldwide, in spite of all the ongoing research in the field of oncology. While there have been some breakthroughs in the past 50 years, metastatic tumors remain the bane ... -
Non-intrusive reduced order modeling of dynamical systems with large stochastic dimensions
The work done in this thesis falls under the broad category of computational mechanics. This thesis addresses the computational challenge of high-dimensional regression and interpolation within the framework of a proper ... -
Integrating Coarse Semantic Information with Deep Image Representations for Object Localization, Model Generalization and Efficient Training
Coarse semantic features are abstract descriptors capturing broad semantic information in an image, including scene labels, crude contextual relationships between objects in the scene, or even objects described using ... -
Dynamically isotropic Gough-Stewart platform for micro-vibration isolation in spacecraft
Rotating components such as reaction wheels and momentum wheels on spacecraft generate micro-vibrations up to 250 Hz during on-orbit operations. While the use of Gough-Stewart Platforms (GSPs) for six degrees of freedom ... -
Investigations on Flow in Supercritical CO2 Ejectors
Adopting natural eco-friendly refrigerant carbon dioxide (CO2) in energy conversion devices is gaining prominence globally. Supersonic ejectors are passive devices that energize and compress a secondary stream using a ... -
Dielectric property studies on Poly vinylidene fluoride composites with Graphene Oxide and functionalized Carbon nanotube fillers
Embargo up to November 1, 2025 Graphene Oxide (GO) and functionalized Carbon nanotubes (FCNT) are promising materials in the field of polymer composites due to their ability to disperse nicely in the polymer matrix. The ... -
3D printing for biomedical applications: Hybrid nanoparticle reinforced hydrogels for soft tissue regeneration and bone flaps for cranial reconstruction
This dissertation focuses on the quantitative insights into process v science behind the development of tissue-engineered grafts using additive manufacturing (AM) technology. Additive manufacturing, commonly referred to ... -
Hominini-specific regulation of cell cycle by stop codon readthrough of FEM1B
In certain mRNAs ribosomes continue translation beyond the canonical stop codon to generate longer isoform with a C-terminal extension. This phenomenon is termed stop codon readthrough (SCR). Previously, a genome-wide ... -
Dual-Polarized Multi-Frequency Phased Antenna Array with Suppressed Higher Order Modes
5G base stations operating in sub-6 GHz frequencies typically utilize full-dimensional or 3D beamforming with precise steering, using electronically scanned phased array antennas (PAA). Additionally, Radar systems for ... -
Ankora: Notions of Multi-party Computation and Zero-knowledge Beyond Conventional Models
In the era of digitalization, data privacy and integrity are of utmost importance. Secure multiparty computation (MPC) and zero-knowledge (ZK) facilitate data privacy and integrity. MPC enables privacy-preserving collaborative ... -
Computational Studies of Heavier Main Group Elements: Control of Lewis Acidity of Bi and Sb by Charge and Ligand Design, and Structural Variations of [Fe(CO)4]2E2 and E2CH2 Isomers (E = C–Pb)
Traditional main group compounds demonstrate Lewis acidity due to the presence of vacant p- orbitals. Hydrides of lighter main group elements, such as NH3, function as Lewis bases. However, introducing highly electronegative ... -
Photodynamic Therapy and Cellular Imaging using Platinum(II) Conjugates of Boron-dipyrromethene and Curcumin
The present thesis portrays the rational design and successful synthesis of platinum(II) complexes for achieving photoactivated dual action anticancer properties. The research project centers on synthesis, comprehensive ... -
Structural characterization of Staphylococcal γ-hemolysin in the presence of a lipid environment using single particle cryo-EM
γ-Hemolysin (γ-HL) is a quintessential bicomponent β-pore forming toxin (β-PFT) belonging to the arsenal of “superbug” Staphylococcus aureus. Here, we performed negative staining-TEM and single particle cryo-EM-based ... -
Ultrafast Processes in Energetic Molecules
The thesis has been presented in two parts. In first part of the thesis, ultrafast relaxation dynamics of UV excitation induced chemistry via electronically excited states has been discussed. Taking one example from each ... -
PZT Based High-speed Electro-Optic Modulator- Material Development, Fabrication, and Photonic Device Characterization
