Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

NIOM-DGA: Nature-inspired optimised ML-based model for DGA detection [PDF]

Computers & Security
Domain Generation Algorithms (DGAs) allow malware to evade detection by generating millions of random domains daily for Command-and-Control (C&C) communication, challenging traditional detection methods. This work presents NIOM-DGA, a novel machine learning model that applies nature-inspired algorithms (NIAs) to select an optimal subset of 78 features ...
