In this paper, we present a new algorithm for fast correlation attacks on stream ciphers with improved cryptanalysis results on the Sosemanuk stream cipher, one of the 7 finalists in the eSTREAM project in 2008.The new algorithm exploits the direct sum construction of covering codes in decoding phase which approximates the random vectors to a neare

Abstract Background According to recent research, the Internet and social media are shaping and changing how we die and mourn.However, the use of social media after bereavement by suicide remains poorly understood.Thus, emerging research is needed to better assess the role that social media can play after bereavement by suicide.The objective of our

N-containing gaseous compounds, such as trimethylamine (TMA), triethylamine (TEA), ammonia (NH3), nitrogen monoxide (NO), and nitrogen dioxide (NO2) exude irritating odors and are harmful to the human respiratory system at high concentrations.In this study, we investigated the sensing responses of five sensor materials—Al-doped ZnO (AZO) nano
