Elucidating the TSC2-mediated transcriptional regulation of miR-514b-3p
The PI3K-AKT-MTOR signalling axis is pivotal in regulating cell survival, proliferation, and growth. Tuberous sclerosis complex (TSC) is a well-established negative regulator of this pathway, which primarily acts by ... -
Structure-Preserving Physics-Informed Neural Networks for Anisotropic Porous Media with Pressure Dependent Viscosity
Modeling flow through porous media with realistic physical constraints remains a longstanding challenge in subsurface engineering. Anisotropy in permeability, pressure-dependent viscosity, and non-negativity requirements ... -
Robust and Accurate Kinetic Schemes based on Flexible Velocities for Compressible Flows
Kinetic theory based schemes offer a unique approach to numerically solving the hyperbolic nonlinear Euler equations. These methods start with the Boltzmann equation as the governing equation at the kinetic level and then ... -
Influence of population bottlenecks on the evolution of sociality in synthetic life-cycle
Cooperation requires individuals to invest their resources for the benefit of others. Cooperative behaviours often involve the secretion of costly public goods, which can be exploited by spontaneous mutant cheater cells ... -
Investigations on Food Tourism in India
Tourism is vital to the Indian economy, contributing significantly to employment, foreign exchange earnings, and overall economic growth. India attracts millions of domestic and international travelers annually as one of ... -
Some dual realizations of Bergman and Hardy spaces on convex domains via integral transforms
The Fantappi{\`e} and Laplace transforms identify abstract spaces of analytic functionals with concrete function spaces, converting geometric support conditions into analytic growth conditions. Specifically, the space of ... -
Nucleophilic Boron Chemistry: Catalytic approaches to C-X (X= Br, Cl, O, N) Bond Activation in Metal/Metal-free Conditions
The boron-carbon bond occupies a central position in organic synthesis, functioning as a versatile “universal connector” to a broad range of functional groups. As a result, organoboranes have become indispensable synthetic ... -
Machine Learning Methods for Soil property prediction using VNIR and MIR Spectroscopy
Soil plays a key role in food security, freshwater regulation, biodiversity and climate mitigation. Soil intersects directly or indirectly with at least seven of the United Nations Sustainable Development Goals. Among the ... -
Enhancing Privacy and Efficiency of Distributed Encryption
The primary objective of a distributed system is to eliminate reliance on a central authority. In a distributed encryption scheme, users should be able to generate their key materials independently while securely sharing ... -
Tuning the Circuit, Steering the Swarm: CASY-1 in Synaptic and Behavioral Modulation
Disruptions in neuromodulatory signaling are a hallmark of several neurodevelopmental and psychiatric disorders. However, the molecular mechanisms that fine-tune neuromodulation across circuits and behaviors remain poorly ... -
Kobayashi geometry and a metric notion of negative curvature
In this thesis, we study some problems that represent various aspects of Kobayashi geometry. Our problems are, in some sense, motivated by a close examination---which forms a part of this thesis---of a property that may ... -
Structure and Polar Properties of SrTiO3-xNa0.5Bi0.5TiO3 Ferroelectric System
Ferroelectric materials exhibit interesting dielectric and piezoelectric properties. While for over six decades, lead-zirconate titanate (PZT) has been the most sought after piezoelectric material for actuator, transducer, ... -
Complexity and Randomness in the Dynamics of Quantum Systems
This thesis explores two complementary facets of quantum dynamics: the growth of operator complexity in open quantum systems and the certification of quantum randomness from temporal correlations in single-qubit dynamics. ... -
Finite field computational techniques for exact solution of numerical problems
In this dissertation, we consider the application of residue arithmetic for the exact computation of g-inverses in order to obviate the round-off errors normally associated with their computation. It turns out that for ... -
Secondary flows and heat transfer in non-newtonian fluids
The thesis consists of four chapters. In chapter I we have described the non-Newtonian fluids which we have discussed in the text and have also derived the equations of motion in the systems of coordinates which we have ... -
Stability and allied problems in magnetohydrodynamics
We note that the expressions (1.20)�(1.27) are real for all real values of the angular momentum MMM. In the numerical computations, we fixed V0V_0V0? and MMM, then obtained the values of (r,z)(r, z)(r,z) from the given ... -
Some magneto-hydrodynamical problems with an application to astoronomy
Part A: A steady flow with the effect of a controlling field of low conductivity past a rotating cylindrical surface in the case of a dissipative medium and its corresponding flow past a magnetized sphere. Part B: The ... -
Mathematical models of some physiological system
This thesis presents some theoretical investigations on certain problems concerning the respiratory, excretory, and circulatory systems in human physiology, from a fluid mechanics point of view. It consists of an introductory ... -
Hydromagnetic surface waves
The ASW propagates as a dispersive wave along the boundaries of a bounded plasma column. At the interface of a plasma slab surrounded by two identical plasma media, two modes-symmetric and asymmetric-propagate with a phase ... -
Nega-base computer arithemetic-theory and applications
This dissertation presents a detailed study of negative base number representation—the theory as well as the development of suitable algorithms for building the arithmetic unit of a digital computer. The idea of negative ...
