Reconstruction of a dark energy model for the Dirac-Born-Infeld scalar field with the Hubble and DESI data via Gaussian process
Sayantan Ghosh, Gaurav N. Gadbail, P. K. Sahoo +1
In this study, we reconstruct the dark energy (DE) as a Dirac-Born-Infeld (DBI) scalar field from the Hubble dataset (32 CC + 26 BAO) and the DESI dataset using the Gaussian proces…
Robotic Fabric Alignment System for Sewing Using Global Local Weighted ICP
Wenbo Dong, Dipankar Bhattacharya Member, Kai Tang +5
Accurate fabric alignment is a critical step that must be performed before sewing. This paper presents a novel automated fabric alignment system. The system estimates the poses of…
A sound-horizon-free measurement of the Hubble constant from DESI DR2 baryon acoustic oscillations using artificial neural networks
Gaurav N. Gadbail, Kazuharu Bamba
We present a model-independent, sound-horizon-free measurement of the Hubble constant using baryon acoustic oscillation tracers from the Dark Energy Spectroscopic Instrument…
Thermodynamic Topology and Photon Spheres Analysis of Black Holes in Brane-World: Insights from Barrow Entropy
Usman Zafar, Abdul Jawad, Kazuharu Bamba +4
We explore the thermodynamics and geothermodynamics of black holes with Barrow entropy in a brane-world scenario, where the horizon geometry of the black hole is regarded as a frac…
Energy conditions of bouncing solutions in quadratic curvature gravity coupled with a scalar field
Yuki Hashimoto, Kazuharu Bamba, Sanjay Mandal
We examine the validity of classical energy conditions in nonsingular bouncing cosmological solutions arising in quadratic curvature gravity minimally coupled to a scalar field. Fo…
Gravastars on the brane with a timelike extra dimension
Shounak Ghosh, Rikpratik Sengupta, Kazuharu Bamba
We construct a gravastar configuration within the Shtanov-Sahni (SS) braneworld scenario, characterized by a timelike extra dimension and negative brane tension. Unlike classical b…
