Structure-function and evolution of a unique uracil DNA glycosylase, UdgX, from Mycobacterium smegmatis
Mycobacterium smegmatis, a soil bacterium, faces multiple challenges in its environment, including exposure to reactive oxygen species (ROS), reactive nitrogen intermediates (RNI), radiation, and various other chemical ... -
Impact of 3D distribution of Black Carbon aerosols in the atmosphere on aerosol radiative forcing over the Indian region
Black Carbon (BC) aerosols are produced by the incomplete combustion of carbonaceous materials. While they constitute an insignificant mass-fraction of the composite atmospheric aerosols, their measurement is essential in ... -
Studies on Two-Stage Air-Cooled Silica gel + Water Adsorption Cooling System
Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ... -
Robust Station-keeping and High-Precision Attitude Control for a Spacecraft on Sun–Earth L1 Halo Orbit
The halo orbits around the Sun-Earth L1 Lagrange point form an ideal location for deploying a solar observation spacecraft as they offer uninterrupted, long-duration visibility of the Sun. However, the complex orbital and ... -
Understanding the adaptive responses of Salmonella Typhimurium during bile stress
Salmonella Typhimurium (S. Typhimurium) is an enteric pathogen that causes gastroenteritis. Although gastroenteritis is usually non-life threatening in healthy adults, it can cause fatality in children and immunocompromised ... -
Efficient Learning of Koopman Structures for Model-Based Control of Nonlinear Robotic Systems
Identification of the dynamics of a complex robotic system accurately from first principles is challenging and often infeasible. Simplifying assumptions commonly made in modeling such systems often restrict their scope and ... -
Stochastic Methods in Time-Domain Electromagnetic Computations
The world is advancing towards a highly connected, fast data rate, digital trans- formation through communication technologies like 5G and 6G, high-speed data centres, Terahertz imaging etc. High-frequency RF systems are ... -
Self-Assembled Hosts for Applications in Guest Binding and Catalysis
Living organisms can perform complex chemical reactions precisely in the confined pockets of enzymes. In this regard, numerous aesthetic 2D and 3D discrete architectures have been constructed using metal-ligand coordination ... -
Prediction of multi-physical properties of fibre-reinforced composites using deep learning
This work develops a convolutional neural network (CNN) based surrogate model for simultaneous multi-physical property prediction from the binary images of fibre-reinforced composites representative volume elements (RVEs). ... -
Collective Magnetic Phases with Pentavalent Iridates
Magnetism and magnetism-driven phenomena have always remained a central theme of modern condensed matter physics. Conventional magnetic transition, such as para magnetic to ferromagnetic phase, involves symmetry breaking ... -
Studies on EEG correlates of non-ordinary states of consciousness and slow-paced breathing
Studies on the non-ordinary states of consciousness (NSCs) induced by meditation, hypnosis, trance, and slow-paced breathing are gaining visibility due to their potential efficacy in treating various clinical conditions. ... -
Temporal Point Processes for Forecasting Events in Higher-Order Networks
Real-world systems consisting of interacting entities can be effectively represented as time-evolving networks or graphs, where the entities are depicted as nodes, and the interactions between them are represented as ... -
