Galactic cosmic rays from star clusters and nearby supernovae remnants
Cosmic rays (CRs) are high-energy particles, predominantly originating from outside the Earth’s atmosphere. These particles, ranging from protons to heavier nuclei, propagate through space at nearly the speed of light, ... -
Crystal Structure of an Effector Histone Methyltransferase Rv2067c from Mycobacterium tuberculosis H37Rv: Structural Insights into Context-Dependent Substrate Recognition Structure and Dynamics of a GNAT Family Protein Acetyltransferase HP0935 from a Gastric Pathogen Helicobacter pylori 26695
Methylation of histones is one of the important gene regulation mechanisms in eukaryotes. Histone methylation has a role in immune response to the invading pathogens. Pathogens implement effector proteins that evade host ... -
Proposals for probing BSM in unexplored corners of Top physics and Next-to-Minimal Supersymmetric Standard Model (NMSSM)
Despite its triumphs, the Standard Model (SM) fails to address many experimental observations and theoretical puzzles. Explanation of these necessitates postulation of new physics beyond those in the SM (BSM). The thesis ... -
The influence of temperature and bias voltage on bulk and two-dimensional bismuth sulfide for optoelectronic applications
The field of optoelectronics seeks sustainable, abundant, and cost-effective materials that can reliably perform under varying environmental conditions. Bismuth sulfide (Bi2S3), a narrow bandgap (1.3 eV) semiconductor has ... -
