Viscous cosmology in the Weyl-type gravity
Gaurav Gadbail, Simran Arora, P. K. Sahoo
Bulk viscosity is the only viscous influence that can change the background dynamics in a homogeneous and isotropic universe. In the present work, we analyze the bulk viscous cosmo…
Metadata Shaping: Natural Language Annotations for the Tail
Simran Arora, Sen Wu, Enci Liu +1
Language models (LMs) have made remarkable progress, but still struggle to generalize beyond the training data to rare linguistic patterns. Since rare entities and facts are preval…
Power-law cosmology in Weyl-type gravity
Gaurav Gadbail, Simran Arora, P. K. Sahoo
Gravity is attributed to the spacetime curvature in classical General Relativity (GR). But, other equivalent formulation or representations of GR, such as torsion or non-metricity…
A complete study of conformally flat pseudo-symmetric spacetimes in the theory of F(R)-gravity
Avik De, Simran Arora, Uday Chand De +1
We investigate the geometrical and physical structures of a pseudo-symmetric spacetime with timelike vector under the condition of conformal flatness. We classify it into…
On the Opportunities and Risks of Foundation Models
Rishi Bommasani, Drew A. Hudson, Ehsan Adeli +111
AI is undergoing a paradigm shift with the rise of models (e.g., BERT, DALL-E, GPT-3) that are trained on broad data at scale and are adaptable to a wide range of downstream tasks.…
Bulk viscous matter and the cosmic acceleration of the universe in gravity
Simran Arora, S. K. J. Pacif, Abhishek Parida +1
We have studied bulk viscosity in the modified gravity theory formalism, where represents the non-metricity and denotes the trace of energy-momentum tensor within…
