Coded Caching in Multi-access Networks
Caching is a promising technique that can reduce the amount of data transmitted over latency-prone links, effectively trading affordable memory for expensive bandwidth resources. The frequently demanded content is stored ... -
Estimation of the spatial spread of brain signals at multiple scales
Spatial spread of a particular brain signal can be defined as the area of the cortical tissue around the recording electrode that contributes to the electrical activity recorded by the electrode. More specifically, ... -
Biochemical, Genetic and Molecular characterization of TCP3 and TCP4 transcription factors in Arabidopsis thaliana
The TEOSINTE BRANCHED1, CYCLOIDEA, PROLIFERATING CELL FACTORs (TCP) family of proteins consists of plant-specific, non-canonical basic helix-loop-helix transcription factors that perform diverse developmental processes. ... -
Efficient and Resilient Stream Processing in Distributed Shared Environment
Internet of Things (IoT) deployments comprising of sensors and actuators collect observational data and provide continuous streams of data, often called streaming data or fast data. Smart Cities use such IoT technologies ... -
Checking Observational Purity of Procedures
We provide two static analysis approaches(using theorem proving) that check if a given (recursive) procedure behaves as if it were stateless, even when it maintains state in global variables. In other words, we check if ... -
Aβ42-mediated dendritic spine loss in an in-vitro model of Alzheimer’s disease
The results from this study establish the molecular mechanism underlying the Aβ42-mediated dendritic spine loss observed in the APP/PS1 mouse model of AD. Further, this study highlights the role of Aβ42 in altering the ... -
Alluaudite Class of High-Voltage Cathodes for Sodium-Ion Battery Applications: A Synthesis, Structure, Property Correlation Study
The work presented in this thesis demonstrates alluaudites as a niche class of compounds forming the rich treasure house of sodium insertion hosts. The potential of this open frame-worked alluaudites is immense and ... -
Applications of Holography
This thesis consists of four parts. In the first part of the thesis, we investigate the phase structure of Einstein-Maxwell-Scalar system with a negative cosmological constant. For the conformally coupled scalar, an ... -
Internal resonances and nonlinearities in atomically thin resonators
The advent of carbon nanotubes (CNTs) and atomically thin membranes such as Graphene and layered transition metal chalcogenides (TMDs) have spurred research in the area of Nanoelectromechanical Systems (NEMS) due to their ... -
Bayesian Techniques for Joint Sparse Signal Recovery: Theory and Algorithms
This thesis contributes new theoretical results, solution concepts, and algorithms concerning the Bayesian recovery of multiple joint sparse vectors from noisy and underdetermined linear measurements. The thesis is written ... -
A Novel Algorithm-Architecture Co-Designed System for Dynamic Execution-Driven Pre-Silicon Verification
In EDA industry, design-under-test (DUT) is a pre-silicon digital design which is still undergoing testing phase. We perform functional-verification of a DUT to verify whether the DUT conforms to the specifications. Functional ... -
Role of conserved features of initiator tRNA and ribosome heterogeneity in translation initiation in Escherichia coli
Translation is one of the fundamental and core cellular processes catalysed by a ribonucleoprotein complex called ribosome. The process involves four major steps: initiation, elongation, termination and recycling. Initiation ... -
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
Role of TCP transcription factors in seedling development, leaf morphogenesis and senescence in Arabidopsis thaliana
The TCP gene family encodes non-canonical bHLH transcription factors that act as key regulatory molecules in diverse developmental processes in plants including organ morphogenesis, plant architecture, leaf maturation, and ... -
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied for decades with only minor improvements. Boundary layer transition to turbulence in highMach number flow is one such topic, which, ... -
Design and Synthesis of Cyclic Diselenides and Selenenyl Sulfides for Biomimetic Applications
Hydrogen peroxide (H2O2) plays important roles in cell signaling and redox reactions. However, elevated levels of H2O2 and organic peroxides induce oxidative stress, resulting in damage to biomolecules such as DNA, ... -
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ... -
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ... -
Genetics of Glioblastoma: Insights into Biology and Therapy Resistance
The central nervous system contains the neural stem cells which differentiate and give rise to the neurons as well as the glial cells which are non-neuronal in nature and provide support and protection to neurons. Unlike ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ...
