Impact of van der Waals epitaxy on structural and optoelectronic properties of layered solids
Emergence of Graphene, Transition metal dichalcogenides (TMDCs) and other van der Waals materials promises to rede fine the building blocks of the future materials and technologies. These materials have gained enormous ... -
Generation and Bandwidth Scaling of silicon modulator based Integrated High Repetition rate Optical Frequency Combs
Optical Frequency Combs (OFC) are laser sources that consist of discrete, equally spaced lines in frequency space, have found extensive use in metrology, spectroscopy, sensing and optical communications. Generation of ... -
Efficient Algorithms for Learning Restricted Boltzmann Machines
The probabilistic generative models learn useful features from unlabeled data which can be used for subsequent problem-specific tasks, such as classification, regression or information retrieval. The RBM is one such important ... -
Modified-graphene and carbon nanodots for nitrogen dioxide sensing: Effects of interfacial electronic modulation and dimensionality on gas interaction
Currently, there is an enormous demand for the development of high performance nitrogen dioxide (NO2) gas sensors for environmental pollution monitoring. Hence, there is a constant quest to replace traditional metal oxide ... -
Structural and functional studies on DNA damage inducible protein 1 (Ddi1) from protozoa
Structural and functional investigations on DNA-damage inducible protein1 (Ddi1) from Entamoeba histolytica, Trypanosoma cruzi and Toxoplasma gondii have been carried out. Ddi1 belongs to the ubiquitin receptor family of ... -
Design, Synthesis and Conformational Analysis of Hydrogen Bond Surrogate (HBS) Stabilized Helices in Natural Sequences. Helically Constrained Peptides for Potential DNA-Binding
Thesis titled, “Design, Synthesis and Conformational Analysis of Hydrogen Bond Surrogate (HBS) Stabilized Helices in Natural Sequences. Helically Constrained Peptides for Potential DNA-Binding”, describes the development ... -
Wide Band Gap Oxides as the Probes for Optical Based Sensing Applications
Temperature is a very critical and widely measured variable by both researchers and engineers. In this regard, most of the available temperature sensors are based on contact mode of operation. In this consideration, the ... -
Computational Investigation of Heterogeneous Lateral Organisation in Biological Membrane
The study of lateral heterogeneity on membrane surface has come a long way from the fluid mosaic model. Simulations and experimental studies have observed non-random mixing of lipids and proteins in the membrane. In this ... -
Local Structural Investigations of Composition-driven Changes in Inorganic Solid Solutions
A smaller sized dopant replacing a larger sized element in a compound creates chemical pressure, resulting in a contraction of the lattice parameter and likewise a “negative” pressure is created by substitution of larger ... -
Studies on alkali activated compressed earth bricks for structural masonry
Earth based construction materials are acknowledged as low carbon and low embodied energy materials. The investigations dealt in the thesis were mainly focused on exploring the geopolymer and lime-ground slag binders for ... -
Vibrational Spectroscopic studies of Dynamics of BSA unfolding, Lysozyme-Ethanol interaction and Tissue Imaging
Vibrational spectroscopy has served as a powerful tool for understanding various structural properties of the molecules since decades. In the recent years, it has also emerged as an invaluable tool in understanding various ... -
A framework for optimizing immunotherapy for long-term control of HIV
HIV infects around 1 million people every year. Antiretroviral therapy (ART) is used to suppress viral replication and control disease progression but it cannot eradicate the virus. ART is therefore lifelong. Today, e ... -
EMF: System Design and Challenges for Disaggregated GPUs in datacenters for Efficiency, Modularity and Flexibility
With Dennard Scaling phasing out in the mid-2000s, architectural scaling and hardware specialization take centre stage to provide performance bene fits with already stalling Moore's law. An outcome from this hardware ... -
Development of Synchro-Phasor Algorithms on Parallella - A Credit Card Sized Super Computer
In recent years, usage of GPS time-stamped phasor magnitude and angle measure- ments of voltage and current samples, called synchrophasors, is getting great atten- tion for wide area monitoring, protection, and control ... -
Low Power Analog Neural Network Framework with MIFGMOS
Ever since the beginning of the notion behind the term 'cloud computing,' i.e., to share the pro- cessing and storage capabilities of a centralized system, there has been a signi cant increase in the availability of raw ... -
SRF regulates the generation of neuroprotective astrocytes in the brain
In response to injuries, infections or in neurodegenerative disorders, astrocytes get activated to become reactive. This phenomenon is called astrogliosis and is marked by a spectrum of changes which encompasses structural, ... -
Trends and Variability in Terrestrial Carbon Fluxes and Stocks over India in the 20th and 21st centuries: A Multi-model Based Assessment
Terrestrial ecosystems play an important role in the global carbon cycle by naturally taking up carbon from the atmosphere through photosynthesis and storing this carbon as biomass and soil carbon. There exists a strong, ... -
Coarse-grained dynamics derived structural ensemble for prediction of metal binding sites of protein and phenotypic effects of variants
Structures of proteins play a key role in determining their functions. Knowledge of structure, especially the details of specific sites of a protein can help us understand their contribution to the overall activity. ... -
Neural Representation Learning for Speech and Audio Signals
Representation learning is the branch of machine learning consisting of techniques that are capable of automatically discovering meaningful representations from raw data for efficient information extraction. In recent ... -
The influence of landscape composition on butterfly populations: A behavioural ecological approach
Overall, taking behavioural ecological and trait-based approaches, my study suggests that the distribution of a species and patterns in its population densities in a landscape are affected by diverse ecological variables, ...
