Eavesdropping Mobile App Activity via Radio-Frequency Energy Harvesting

Radio-frequency (RF) energy harvesting is a promising technology for Internet-of-Things (IoT) devices to power sensors and prolong battery life. In this paper, we present a novel side-channel attack that leverages RF energy harvesting signals to eavesdrop mobile app activities. To demonstrate this novel attack, we propose AppListener, an...

Ultra-low-frequency radio astronomy observations from a Seleno-centric orbit: First results of the Longjiang-2 experiment

This paper introduces the first results of observations with the Ultra-Long-Wavelength (ULW) —- Low Frequency Interferometer and Spectrometer (LFIS) on board the selenocentric satellite Longjiang-2. We present a brief description of the satellite and focus on the LFIS payload. The in-orbit commissioning confirmed a reliable operational status...

A Novel Unspecific Peroxygenase from Galatian marginata for Biocatalytic Oxyfunctionalization Reactions

Unspecific peroxygenases (UPOs, EC 1.11.2.1) are promising oxyfunctionalization catalysts because of their unique stereoselectivity. However, so far only a few UPOs have been reported. In this study, gene mining was used to identify a gene from Galerina marginata that coded for a novel UPO (GmaUPO). GmaUPO was expressed in Pichia pastoris X...

How To Break the Janus Effect of H ₂ O ₂ in Biocatalysis? Understanding Inactivation Mechanisms To Generate more Robust Enzymes

H ₂ O ₂ , is an attractive oxidant for synthetic chemistry, especially if activated as percarboxylic acid. H ₂ O ₂ , however, is also a potent inactivator of enzymes. Protein engineering efforts to improve enzyme resistance against H ₂ O ₂ in the past have mostly focused on...
