Structural Properties of Magnetized Neutron Stars under f (R, T ) Gravity Framework
Charul Rathod, M. Mishra, Prasanta Kumar Das
The current work investigates the structural properties of neutron stars in the presence of a strong magnetic field within the framework of f(R,T) modified gravity, where the matte…
Robust stability and preconditioning of Darcy-Forchheimer equations
Rishi Das, Harsha Hutridurga, Amiya K. Pani +1
We derive parameter-robust quasi-optimal error estimates for mixed finite element methods for the nonlinear Darcy--Forchheimer equations with mixed boundary conditions. Using the f…
Symbolic Neural Generation with Applications to Lead Discovery in Drug Design
Ashwin Srinivasan, Tirtharaj Dash, A Baskar +3
We investigate a relatively under-explored class of hybrid neurosymbolic models that integrate symbolic learning with neural reasoning to construct data generators meeting formal c…
Skill, Will, or Both? Understanding Digital Inaccessibility from Accessibility Professionals' Viewpoint
P D Parthasarathy, Rachel F. Adler, Devorah Kletenik +2
Digital inaccessibility continues to be a significant barrier to true inclusion and equality. WebAIM's 2024 report reveals that only 4.1% of the world's top one million website hom…
Scaling Accessibility Education: Reflections from a Workshop Targeting CS Educators and Software Professionals
P D Parthasarathy, Anshu M Mittal, Swaroop Joshi
Despite growing global attention to digital accessibility, research from India highlights a significant gap in accessibility training for both computing educators and software prof…
AI Ethics Education in India: A Syllabus-Level Review of Computing Courses
Anshu M Mittal, P D Parthasarathy, Swaroop Joshi
The pervasive integration of artificial intelligence (AI) across domains such as healthcare, governance, finance, and education has intensified scrutiny of its ethical implications…
Effect of Dark matter and -cut potential on radial and non-radial oscillation modes in neutron stars
Prashant Thakur, Ishfaq Ahmad Rather, Y. Lim
We study the mesonic nonlinear (NL) interaction equation of state (EoS) employing the relativistic mean-field model and investigate the effect of -cut potential (NL- cut) and…
