Galaxies undergo perturbations, either gravitational or hydrodynamic in origin, which can generate extragalactic structures such as rings and tails, where in situ star formation ma…
Star formation in interacting galaxy systems: UVIT imaging of NGC 7252 and NGC 5291
Geethika Santhosh, Rakhi R, Koshy George +2
Interactions play a significant role in the formation and evolution of galaxies in the Universe. The galaxy systems, NGC 7252 and NGC 5291 are two nearby interacting systems that a…
Turbulence dynamics and flow speeds in the inner solar corona: Results from radio-sounding experiments by the Akatsuki spacecraft
Richa N. Jain, R. K. Choudhary, Anil Bhardwaj +3
The solar inner corona is a region that plays a critical role in energizing the solar wind and propelling it to supersonic and supra-Alfvenic velocities. Despite its importance, th…
Chandrayaan-3 Alternate Landing Site: Pre-Landing Characterisation
K. Durga Prasad, Dibyendu Misra, Amitabh +5
India's third Moon mission Chandrayaan 3 will deploy a lander and a rover at a high latitude location of the Moon enabling us to carry out first ever in-situ science investigations…
Recognition of chordal graphs and cographs which are Cover-Incomparability graphs
Arun Anil, Manoj Changat
Cover-Incomparability graphs (C-I graphs) are an interesting class of graphs from posets. A C-I graph is a graph from a poset with vertex set , and the edge-set is t…
Steady state correlations and induced trapping of an inertial AOUP particle
N Arsha, K P Jepsin, M Sahoo
We study the dynamics of an inertial active Ornstein-Uhnlenbeck particle self-propelling in a confined harmonic well. The transport behaviour of the particle is investigated by ana…
Inertial active Ornstein-Uhlenbeck particle in the presence of magnetic field
M Muhsin, M Sahoo
We consider an inertial active Ornstein-Uhlenbeck particle in an athermal bath. The particle is charged, constrained to move in a two-dimensional harmonic trap, and a magnetic fiel…
Variability-aware Memristive Crossbars -- A Tutorial
Alex James, Leon Chua
Memristor crossbar architecture is one of the most popular circuit configurations due to its wide range of practical applications. The crossbar architecture can emulate the weighte…
First-order logic axiomatization of metric graph theory
Jérémie Chalopin, Manoj Changat, Victor Chepoi +1
The main goal of this note is to provide a First-Order Logic with Betweenness (FOLB) axiomatization of the main classes of graphs occurring in Metric Graph Theory, in analogy to Ta…
TMS-Crossbars with Tactile Sensing
R. Chithra, A. R. Aswani, A. P. James
The first stage of tactile sensing is data acquisition using tactile sensors and the sensed data is transmitted to the central unit for neuromorphic computing. The memristive cross…
Accuracy and speed of elongation in a minimal model of DNA replication
M Sahoo, Arsha N, P R Baral +1
Being a dual purpose enzyme, the DNA polymerase is responsible for elongation of the newly formed DNA strand as well as cleaving the erroneous growth in case of a misincorporation.…
Orbital Magnetism of Active Viscoelastic Suspension
M Muhsin, M Sahoo, A Saha
We consider a dilute suspension of active (self-propelling) particles in a visco-elastic fluid. Particles are charged and constrained to move in a two dimensional harmonic trap. Th…
Low-dimensional magnetism of BaCuTeO
