A brief overview of Turkiye Earthquake: insight into the building damage
Rajib Biswas
The month of February 2023 had been a nightmare for the people of Turkiye. On 6th Feb, there was a devastating earthquake which jolted Turkiye like never before. The aftershock whi…
Effects of hydrophobic solute on water normal modes
Kambham Devendra Reddy, Albin Joy, Rajib Biswas
The vibrational modes of water get significantly modified by external solutes; this becomes particularly important when the solute is hydrophobic. In this work, we examine the effe…
Spatial variation of Coda Q in Kopili fault zone of northeast India as a probe for heterogeneous media
Nilutpal Bora, Rajib Biswas
Kopili fault has been experiencing higher seismic and tectonic activity ([1], [2]) during the recent years. These kinds of active tectonics can be inspected by examining coda-wave…
Theoretical Spectroscopic Investigation of Hydrogen Bonding and Hydrophobicity
Kambham Devendra Reddy, Rajib Biswas
Hydrophobic solutes significantly alters water hydrogen bond network. The local alteration of solvation struc-tures get reflected in the vibrational spectroscopic signal. Although…
CodaQback: A simplified Python Code facilitating auto-windowing for estimating Seismic Coda attenuation parameter
Nilutpal Bora, Rajib Biswas, S Vassudevan
Attenuation study of a province is considered as a basic quantity for seismic hazard assessment, ground motion simulation process and source parameter studies. It is already establ…
Influence of probe geometry of optical fibers in sensing volatile liquids through localized surface plasmon resonance
R. Biswas, D. Paul, B. S. Boruah
A comprehensive analysis of influence of probe geometry on localized surface plasmon resonance phenomenon is presented. Plasmonic responses of noble metal nanoparticles such as AuN…
Role of radon as a precursor to earthquakes:An appraisal
R. Biswas
Radon monitoring has recently gained extensive attention among seismologists. It is now widely reported as a precursssory signal prior to occurrence of a seismic event. The enhance…
Inexpensive hetero-core spliced fiber optic setup for assessing strain
R. Biswas
We report here a novel experimental scheme for the measurement of strain that utilizes a simple intensity based interrogation system, based on optical fibers. Corresponding to spli…
Assessing site response through H/V ratio in a seismic prone area of northeast India
Rajib Biswas, Saurabh Baruah
We endeavor to assess site response exploiting ambient noise measurements which we carried out at 70 sites in different parts of Shillong City, one of the seismically active region…
Delineating site response from microtremors: A case study
R. Biswas, N. Bora
We report estimation of site response in the form of fundamental frequency. Towards this objective, we deploy widely established receiver function technique. Taking locally recorde…
Quantifying Regional Body-wave attenuation in a seismic prone zone of northeast India
Nilutpal Bora, Rajib Biswas
We evaluated the body wave attenuation parameter in Kopili region of northeast India. Using the modified algorithm of coda normalization method, we delineated frequency-dependent a…
Diffusion in a rough potential revisited
Saikat Banerjee, Rajib Biswas, Kazuhiko Seki +1
Rugged energy landscapes find wide applications in diverse fields ranging from astrophysics to protein folding. We study the dependence of diffusion coefficient of a Brownian…
Melting/freezing transition in polydisperse Lennard-Jones system: Remarkable agreement between predictions of inherent structure, bifurcation phase diagram, Hansen-Verlet rule and Lindemann criteria
Sarmistha Sarkar, Rajib Biswas, Partha Pratim Ray +1
We use polydispersity in size as a control parameter to explore certain aspects of melting and freezing transitions in a system of Lennard-Jones spheres. Both analytical theory and…
Phase transition in magnetically coupled spins on a ring (SOR) model
Rajib Biswas, Biman Bagchi
We have considered a new type of 'XY' model where spins are placed on concentric ring with constant spin density in every ring. The spin executes continuous rotation under a modifi…
Dynamic coupling between the LID and NMP domain motions in the catalytic conversion of ATP and AMP to ADP by adenylate kinase
Biman Jana, Bharat V. Adkar, Rajib Biswas +1
The catalytic conversion of ATP and AMP to ADP by adenylate kinase (ADK) involves large amplitude, ligand induced domain motions, involving the opening and the closing of LID and N…
A kinetic Ising model study of dynamical correlations in confined fluids: Emergence of both fast and slow time scales
Rajib Biswas, Biman Bagchi
Experiments and computer simulation studies have revealed existence of rich dynamics in the orientational relaxation of molecules in confined systems such as water in reverse micel…
