Autor: Alqattan, D, Sun, R, Liang, H, Nicosia, G, Snasel, V, Ranjan, R, Ojha, V

Publikováno v: 33rd International Conference on Artificial Neural Networks (ICANN) (2024)

Hierarchical federated learning (HFL) is a promising distributed deep learning model training paradigm, but it has crucial security concerns arising from adversarial attacks. This research investigates and assesses the security of HFL using a novel m

Interacting tachyonic scalar field II

Autor: Ojha, V K, Rao, Adithya A, Pathak, S D

The existence of dark energy is essential to explain the cosmic accelerated expansion. We consider a homogenous interacting tachyonic scalar field as a possible candidate for the dynamical dark energy. The interaction between the tachyonic field and

Interacting tachyonic scalar field

Autor: Kundu, A, Pathak, S D, Ojha, V K

Publikováno v: Commun. Theor. Phys. 73 025402(2021)

We discuss the coupling between dark energy and matter by considering a homogeneous tachyonic scalar field as a candidate for dark energy. We obtained the functional form of scale factor by assuming that the coupling strength depends linearly on the

Novel synthesis of topological insulator based nanostructures (Bi2Te3) demonstrating high performance photodetection

Autor: Sharma, Alka, Senguttuvan, T D, Ojha, V N, Husale, Sudhir

Publikováno v: Scientific Reports, 9, 3804, 2019

The rapid progress in 2D material research has triggered the growth of various quantum nanostructures-nanosheets, nanowires, nanoribbons, nanocrystals and the exotic nature originating through 2D heterostructures has extended the synthesis of hybrid

Proximity-induced supercurrent through topological insulator based nanowires for quantum computation studies

Autor: Bhattacharyya, Biplab, Awana, V. P. S., Senguttuvan, T. D., Ojha, V. N., Husale, Sudhir

Publikováno v: Scientific Reports (2018) 8:17237

Proximity induced superconducting energy gap in the surface states of topological insulators has been predicted to host the much wanted Majorana fermions for fault tolerant quantum computation. Recent theoretically proposed architectures for topologi

Light Induced Electron-Phonon Scattering Mediated Resistive Switching in Nanostructured Nb Thin Film Superconductor

Autor: Kazim, Shafaq, Sharma, Alka, Yadav, Sachin, Gajar, Bikash, Joshi, Lalit M., Mishra, Monu, Gupta, Govind, Husale, Sudhir, Gupta, Anurag, Sahoo, Sangeeta, Ojha, V. N.

Publikováno v: Scientific Reports, 7, 881 (2017)

The elemental Nb is mainly investigated for its eminent superconducting properties. In contrary, we report of a relatively unexplored property, namely, its superior optoelectronic property in reduced dimension. We demonstrate here that nanostructured
