Abstract: The proper functioning of the river ecosystem has been symbolised by healthy aquatic life. The river Ganga has shown signs of rejuvenation due to lockdown. In this study, an attempt has been made to analyse the ...
Discovery of Histone Deacetylase Inhibitor Using Molecular Modeling and Free Energy Calculations

Mishra, Abha; Singh, Amit (American Chemical Society, 2022-05)

The histone acetylation-deacetylation at lysine regulates the functions of many cellular proteins. An increased expression of HDAC6 can cause an increased amount of deacetylated histones, which leads to an inhibition of ...
Design and Analysis of Biomedical Scaffolds Using TPMS‐Based Porous Structures Inspired from Additive Manufacturing

Gyroid (G) and primitive (P) porous structures have multiple application areas, ranging from thermal to mechanical, and fall in the complex triply periodic minimal surface (TPMS) category. Such intricate bioinspired ...
Computational identification of natural product inhibitors against EGFR double mutant (T790M/L858R) by integrating ADMET, machine learning, molecular docking and a dynamics approach

Agarwal, Subhash M; Nandekar, Prajwal; Saini, Ravi (Royal Society of Chemistry, 2022-06)

Double mutated epidermal growth factor receptor is a clinically important target for addressing drug resistance in lung cancer treatment. Therefore, discovering new inhibitors against the T790M/L858R (TMLR) resistant ...
Bending waves in velocity space: A first look at the THINGS sample

Nandakumar, Meera; Narayan, Chaitra; Dutta, Prasun (Oxford University Press, 2022-06-01)

Detection of bending waves is a highly challenging task even in nearby disc galaxies due to their sub-kpc bending amplitudes. However, simulations show that the harmonic bending of a Milky Way-like disc galaxy is associated ...
Langmuir-Blodgett monolayer of electrochemically synthesized PANI-TiO2 nanocomposites for MSG biosensor

Sharma, Devdutt; Dutta, Hemant Sankar; Dhayal, Marshal (Elsevier B.V., 2022-08)

Nanocomposites of polyaniline titanium oxide (PANI-TiO2) have been synthesized by employing the electrochemical technique and their monolayers were prepared on a pre-chemical treated indium tin oxide (ITO) surface through ...
Physical link of the polar field buildup with the Waldmeier effect broadens the scope of early solar cycle prediction: Cycle 25 is likely to be slightly stronger than Cycle 24

Kumar, Pawan; Biswas, Akash; Karak, Bidya Binay (Oxford University Press, 2022-06-01)

Prediction of the solar cycle is challenging but essential because it drives space weather. Several predictions with varying amplitudes of the ongoing Cycle 25 have been made. We show that an aspect of the Waldmeier effect ...
Evaluation of ground vibrations induced by blasting in a limestone quarry

Paurush, Punit; Rai, Piyush (Indian Academy of Sciences, 2022-06)

Despite being a versatile and low-cost method, rock blasting produces undesirable severe effects. The pre-sent study aims to examine the ground vibrations pro-duced by blasting, which are of serious concern to mine operators ...
