Fluid Flow as Transport of Probability: Entropy, Compressibility, and Irreversibility
Ankit Bhattacharjee
The continuity equation serves as a fundamental principle for mass transport in continuous media. While its mathematical structure mirrors that of probability transport and the Lio…
Effects of radial conductivity variation on the Ponomarenko dynamo
Shipra Verma, Kannabiran Seshasayanan
We study the effects of conductivity variation on the Ponomarenko dynamo. Taking monotonically increasing/decreasing and sinusoidally varying radial profiles, we study the kinemati…
Large small-scale kinematic dynamo in protoneutron stars
Shipra Verma, Kannabiran Seshasayanan, Raphaël Raynaud +1
Magnetars are young, isolated neutron stars that possess an exceptionally strong magnetic field, with surface dipolar strengths on the order of G. One of the plausible sc…
Sequence Recognition in Bharatnatyam dance
Himadri Bhuyan, Rohit Dhaipule, Partha Pratim Das
Bharatanatyam is the oldest Indian Classical Dance (ICD) which is learned and practiced across India and the world. Adavu is the core of this dance form. There exist 15 Adavus and…
Signatures of charged rotating regular black holes: quasinormal modes, grey-body factors and shadows
Abhisek Barman Maji
We construct and study possible astrophysical signatures of the rotating counterparts of two charged regular black holes, namely the Ayón--Beato--García (ABG) and Balart--Panotopou…
Phonon anomalies and critical scaling in the spin- trimer chain NaCuGeO
P. Srikanth Patnaik, A. K. Bera, Srishti Bhardwaj +4
Low-dimensional quantum magnets provide an ideal platform to explore spin-lattice coupling-mediated quantum correlations, which give rise to emergent quasiparticle excitations. The…
Orbital Hybridization Induces Giant Cubic Rashba Effect at Cu/WO Interface
Md Aktar Hossain, Saikat Das
Harnessing Rashba spin-orbit interaction and related spintronic functionalities has traditionally relied on metallic surfaces or interfaces containing elemental heavy metals. Here,…
Curvature-Weighted Gradient Diversity: A Noise Measure for Geometry-Adaptive SGD Schedules
Muhammad Hamza, Ayush Goel
The standard convergence analysis of mini-batch stochastic gradient descent (SGD) models gradient noise using a single variance term that treats all parameter directions equally, i…
Radio emission from ultra-diffuse galaxies residing in galaxy clusters
Dharam V. Lal, Jeyasiona Murugesh
Ultra-diffuse galaxies (UDGs), defined by their extremely low surface brightness (-band mag arcsec) and large effective radii (3--10 arcsec), remain one of…
Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21
The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…
Impact of Disorder Dynamics and Multi-Domain Kinetics on the Sliding Ferroelectricity of CVD-Grown 3R-WSe2 Bilayers
Sourav Paul, Prasenjit Ghosh, Krishna Prasad Maity +9
Sliding ferroelectricity in van der Waals (vdW) layered systems has emerged as a promising route toward non-volatile nanoscale devices, where interlayer displacement in non-centros…
Co-rotating Vortices on Surfaces of Variable Negative Curvature: Hamiltonian Structure and Curvature-Induced Drift
Gaurang Mangesh Joshi, Rickmoy Samanta
Vortices in fluids and superfluids are fundamental to phenomena ranging from Bose-Einstein condensates and superfluid films to neutron stars and hydrodynamic micro-rotors, where ba…
MTRBO: Multiple trust-region based Bayesian optimization
Sourav Das, Debjani Chakraborty, Pabitra Mitra
Bayesian Optimization (BO) is a popular framework for optimizing black-box functions. Despite its effectiveness, BO is often inefficient for high-dimensional problems due to the ex…
Two-dimensional clay channels for tunable nanofluidic memristor
Sangeeta Yadav, Raj Kumar Gogoi, Aziz Lokhandwala +4
Dynamic reconfiguration of charge carriers in confined ion-channels under electrical stimulation produces memory effects, where the internal resistance depends on history of the el…
Non-Floquet oscillations of a parametrically driven rigid planar pendulum
Rebeka Sarkar, Krishna Kumar, Sugata Pratik Khastgir
The linear and nonlinear motions of a damped rigid planar pendulum, driven by vibrating its pivot sinusoidally, are reexamined. The pendulum is known to exhibit periodic, quasiperi…
EXTree: Towards Supporting Explainability in Attribute-based Access Control
Shanampudi Pranaya Chowdary, Shamik Sural
With increasing emphasis on transparency in digital governance, users expect more than silence when their access requests are denied by a system. However, authorization methods are…
MuSimA: A Tool with Multi-modal Input for Generating Bespoke ABAC Datasets
Saket Jha, Karthikeya S. M. Yelisetty, Singabattu Sathya +1
Recent advances in research on Attribute-based Access Control (ABAC) has led to the development of several ingenious methods for representing and enforcing organizational security…
AFGNN: API Misuse Detection using Graph Neural Networks and Clustering
