Braking indices as probes of r-mode spin-down in young pulsars
Shahram Abbassi, Armin Memarian, Evelyn Sophia Guest +1
The paper develops a timing-based framework using a four‑torque spin‑down model to interpret braking‑index measurements of young pulsars and to constrain possible r‑mode (current‑q…
Restricted nonlinear shrinkage of high-dimensional residual covariance matrices in multivariate regressions
Hamid Karamikabir, Mohammad Arashi
We study estimation of the p*p residual scatter (shape) matrix in a high-dimensional multivariate linear regression, where p and n grow proportionally. When the coefficient matrix…
Mens: Nonlinear shrinkage estimation in nonparanormal models for financial applications
Hamid Karamikabir, Mohammad Arashi
We develop a theory of nonlinear shrinkage covariance estimation for nonparanormal (Gaussian-copula) models, in which each observed coordinate is an unknown strictly increasing tra…
Quantum Adversarial Machine Learning: From Classical Adaptations to Quantum-Native Methods
Roozbeh Razavi-Far, Mohammad Meymani, Erfan Mahmoudinia +6
Machine learning has revolutionized numerous industrial domains. Despite recent advances, machine learning models remain vulnerable to adversarial threats. Adversarial machine lear…
Impact of momentum-dependent drag coefficient on energy loss of charm and bottom quarks in QGP
Marjan Rahimi Nezhad, Fatemeh Taghavi-Shahri, Kurosh Javidan
This paper investigates the influence of heavy-quark momentum on their interaction rate and the resulting drag coefficient in a quark-gluon plasma. To go beyond simplified treatmen…
