The SPOTLIGHT Pulsar Search Pipeline: A GPU-Accelerated FFT Approach
Jyotirmoy Das, Jayanta Roy, Nishant Pradeep Deo +20
We present the pulsar search component of SPOTLIGHT (Survey for sPoradic radiO bursTs via a commensaL multI-beam Gpu-powered Hpc at the gmrT), a GPU-accelerated commensal backend o…
Applications of quantum annealing to magnetic dipole hyperfine structure constants: First results beyond energies for atoms
Boni Paul, Subimal Deb, Per Jönsson +2
We report the first results of the magnetic dipole hyperfine structure (HFS) constants of neutral , Li-like , neutral , and Na-like $\mathrm{…
Coordination-Sensitive Nanoscale Analysis of Defect-Driven Phase Transformation in Si-Doped (AlXGa1-X)2O3
Shaon Das, Jith Sarker, Christopher Chae +5
Defect-driven phase instability critically influences the structural reliability of ultrawide bandgap oxides, yet direct nanoscale metrics linking local chemistry to structural tra…
Distribution Alignment for One-Shot Federated Learning via Optimal Transport
Daniele Berardini, Vito Paolo Pastore, Vittorio Murino
One-Shot Federated Learning (OSFL) addresses extreme communication regimes in which clients interact with the server only once, amplifying the impact of heterogeneous client data d…
Physics-informed time-series forecasting of perovskite photoluminescence stability
Alexander Wieczorek, Manuel Kober-Czerny, Fábio Lopes +5
Accelerated ageing using elevated temperatures and illumination is one of the most common methods to rapidly study the stability of novel semiconductor materials. However, as the p…
