Does the Truthfulness Signal Survive Code-Mixing? Probing Hidden States for Hallucination Detection in Hinglish
Tanveer Singh
Hidden-state hallucination probing - training a linear classifier on an LLM's internal activations to detect whether a generated answer is faithful to the input - is an active area…
Statistical consistency of sign-switching vacuum energy with cosmological observations
Sehjal Khandelwal, Abraão J. S. Capistrano, Suresh Kumar
We assess dataset agreement and late-time predictive adequacy in CDM and its sign-switching extension, CDM, using a suite of Gaussian and exact non-Gaussian consisten…
-CDM: A promising phenomenological extension of the standard model of cosmology
Suresh Kumar
We investigate a phenomenological extension of the standard CDM framework, the -CDM model, in which the total energy density of the universe is expanded in powers of…
Solving Infinite-Horizon Optimal Control Problems using the Extreme Theory of Functional Connections
Tanay Raghunandan Srinivasa, Suraj Kumar
This paper presents a physics-informed machine learning approach for synthesizing optimal feedback control policy for infinite-horizon optimal control problems by solving the Hamil…
New constraints on interacting dark energy from DESI DR2 BAO observations
Emanuelly Silva, Miguel A. Sabogal, Mateus Scherer +3
In its second data release (DR2), the Dark Energy Spectroscopic Instrument (DESI) publicly released measurements of Baryon Acoustic Oscillations (BAO) from over 13.1 million galaxi…
Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +2
The CDM model has successfully explained a wide range of cosmological observations, but is increasingly challenged by the emergence of cosmological tensions, particularly the Hu…
Evaluating Sugarcane Yield Variability with UAV-Derived Cane Height under Different Water and Nitrogen Conditions
Rajiv Ranjan, Tejasavi Birdh, Nandan Mandal +2
This study investigates the relationship between sugarcane yield and cane height derived under different water and nitrogen conditions from pre-harvest Digital Surface Model (DSM)…
Quantifying the tension and evidence for interacting dark energy from redshift-space distortion measurements
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +3
In recent years, Cosmic Microwave Background (CMB) observations, Weak Lensing surveys, and measurements from Redshift-Space Distortions (RSD) have revealed a significant…
CDM cosmology: Alleviating major cosmological tensions by predicting standard neutrino properties
Anita Yadav, Suresh Kumar, Cihad Kibris +1
We investigate a two-parameter extension of the CDM model by allowing variations in the effective number of neutrino species and their total mass $\sum m_ν…
Cosmological constraints on CDM scenario in a type II minimally modified gravity
Özgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5
The idea of a rapid sign-switching cosmological constant (mirror AdS-dS transition) in the late universe at , known as the CDM model, has significantly improve…
Mixed Nonlinear Response and Transition of Nonlinearity in a Piezoelectric Membrane
Nishta Arora, Priyanka Singh, Randhir Kumar +2
Nonlinearities play a critical role in the dynamics of mechanical resonators, enhancing sensitivity and enabling signal manipulation. Understanding the parameters affecting nonline…
