Understanding Syllogistic Reasoning in LLMs from Formal and Natural Language Perspectives
Aheli Poddar, Saptarshi Sahoo, Sujata Ghosh
We study syllogistic reasoning in LLMs from the logical and natural language perspectives. In process, we explore fundamental reasoning capabilities of the LLMs and the direction t…
Sleepy Chauffeur Detection and Alert Techniques for Road Safety
Himel Ghosh, Sayak Chatterjee, Antik Ganguly +2
The most startling of the contemporary problems is the sleepiness of chauffeur which causes lots of car accidents. Prevention of those impending accidents by detecting and alerting…
Phase space analysis of Rényi Holographic dark energy model
Santanu Das, Nilanjana Mahata
Recent observational evidences point out towards a late time acceleration of the universe. In order to study the accelerated expansion, scientists have incorporated the existence o…
From Geometry to Observation: Gravitational Waves and the Raychaudhuri Equation
Sougata Bhunia, Anubhab Dutta, Debashis Gangopadhyay +1
Gravitational waves (GWs) are independent of any particular theory of gravity. The universality of this notion is highlighted by the Raychaudhuri equation (RE), which is independen…
Non-Affine Extensions of the Raychaudhuri Equation in the K-essence Framework
Samit Ganguly, Goutam Manna, Debashis Gangopadhyay +2
We present a new avenue of the Raychaudhuri Equation (RE) by introducing a non-affine parametrization within the k-essence framework. This modification accounts for non-geodesic fl…
Insights of Transitions to Thermoacoustic Instability in Inverse Diffusion Flame using Multifractal Detrended Fluctuation Analysis
Somnath De, Soham Bhattacharya, Arijit Bhattacharya +3
The inverse diffusion flame (IDF) can experience thermoacoustic instability due to variations in power input or flow conditions. However, the dynamical transitions in IDF that lead…
On Laplacian and Distance Laplacian Spectra of Generalized Fan Graph & a New Graph Class
Subarsha Banerjee, Soumya Ganguly
Given a graph , the Laplacian matrix of , is the difference of the adjacency matrix and , where is the diagonal matrix of vertex…
Cosmological implications of non-minimally coupled f(Q) gravity
Santanu Das, Nilanjana Mahata, Priyanka Ray
We experience some challenges in general gravitational theory owing to Einstein to explain late time acceleration of universe. To address this issue, geometric components of gravit…
Search for the origin of wobbling motion in the region: The case of Xe
S. Chakraborty, S. Bhattacharyya, R. Banik +24
In-beam -ray spectroscopy of Xe has been carried out to study the structure of the intruder band. Excited states were populated via an -induced fusion…
Quantum harmonic oscillator in a time dependent noncommutative background
Manjari Dutta, Shreemoyee Ganguly, Sunandan Gangopadhyay
This work explores the behaviour of a noncommutative harmonic oscillator in a time-dependent background, as previously investigated in [1]. Specifically, we examine the system when…
A Dynamic Weighted Federated Learning for Android Malware Classification
Ayushi Chaudhuri, Arijit Nandi, Buddhadeb Pradhan
Android malware attacks are increasing daily at a tremendous volume, making Android users more vulnerable to cyber-attacks. Researchers have developed many machine learning (ML)/ d…
Time Evolution of a Supply Chain Network: Kinetic Modeling
Biswajit Debnath, Rihab El-Hassani, Amit K Chattopadhyay +3
Resilient supply chains are often inherently dependent on the nature of their complex interconnected networks that are simultaneously multi-dimensional and multi-layered. This arti…
Common origin of and dark matter within the flavor symmetric scoto-seesaw framework
Joy Ganguly, Janusz Gluza, Biswajit Karmakar
To understand the observed pattern of neutrino masses and mixing as well as to account for the dark matter we propose a hybrid scoto-seesaw model based on the discrete flavor…
