A novel large-strain kinematic framework for fiber-reinforced laminated composites and its application in the characterization of damage

Shivam, Sandipan Paul

In this paper, a novel kinematic framework for fiber-reinforced composite materials is presented. For this purpose, we use the multiple natural configurations in conjunction with t…

Search for Accelerator-Produced Sub-GeV Dark Matter with the NOvA Near Detector

S. Abubakar, M. Acero, B. Acharya +184

The NuMI facility at Fermilab produces a high-intensity beam of muon neutrinos and antineutrinos, designed to study neutrino oscillations. This beam may also be a source of dark ma…

Asymptotically Optimal Sequential Confidence Interval for the Gini Index Under Complex Household Survey Design with Sub-Stratification

Shivam, Bhargab Chattopadhyay, Nil Kamal Hazra

We examine the optimality properties of the Gini index estimator under complex survey design involving stratification, clustering, and sub-stratification. While Darku et al. (Econo…

Possibility of Meson Condensation in Neutron Star: Unified Approach of Chiral SU(3) Model and QCD Sum Rules

Shivam, Arvind Kumar

In the present work the conjunction of chiral SU(3) model with QCD sum rules is employed to explore the possibility of meson condensation in neutron stars. The quark and gluon…

Joint neutrino oscillation analysis from the T2K and NOvA experiments

NOvA, T2K Collaborations, : +597

The landmark discovery that neutrinos have mass and can change type (or "flavor") as they propagate -- a process called neutrino oscillation -- has opened up a rich array of theore…

Measurement of the double-differential cross section of muon-neutrino charged-current interactions with low hadronic energy in the NOvA Near Detector

M. A. Acero, B. Acharya, P. Adamson +208

The NOvA collaboration reports cross-section measurements for charged-current interactions with low hadronic energy (maximum kinetic energy of 250 MeV for protons and 175 M…
