Thermoplastic epoxy designed using Vitrimer chemistries
Globally, 70 million tons of epoxy thermosets are manufactured at a perplexing rate which constitutes approximately a quarter of polymer generation by weight. A thermosetting polymer contains a permanent crosslinked network ... -
Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ... -
Transition in the Conformational Ensemble of Intrinsically Disordered Proteins: Implications for Phase Separation and Aggregation
Intrinsically disordered proteins (IDPs) are enriched with charged and polar residues and lack a unique three-dimensional structure. Due to the high fraction of charged residues, IDPs are disordered and dynamic, transitioning ... -
Feynman Integral Calculus and Hypergeometric Functions: New Results, Interconnections and Computer Algebra
Feynman integrals play a fundamental role in perturbative calculations within the realm of quantum field theory. In this thesis, we study several important mathematical properties of multi-loop multi-leg Feynman Integrals ... -
Metabolic and Pharmacological Modulations During IFN-γ signaling
Interferons, initially discovered for their antiviral properties, play pivotal roles in various biological processes, including host defense against pathogens, tumor surveillance, and disease pathogenesis. Interferon-gamma ... -
An arbitrary lagrangian eulerian volume of fluid method for floating body dynamics simulation
The floating body dynamics is treated as a Fluid-Structure Interaction (FSI) problem. A FSI problem is where the forces from the fluid move/deform the interacting structure, and the movement of the structure, in turn, ... -
Decentralized information flow control for the robot operating system
The Robot Operating System (ROS) is a popular open-source middleware widely used in the robotics community. While ROS provides extensive support for robotic application develop- ment, it lacks certain fundamental security ... -
