Abstract The current research of sandwich structures under dynamic loading mainly focus on the response characteristic of structure.The micro-topology of core layers would sufficiently influence the property of sandwich structure.However, the micro deformation and topology mechanism of structural deformation and energy absorption are unclear.In thi
Disinformation generates political polarization and affects the quality of democracy, so understanding attitudes towards the regulation of disinformation will help society and its leaders to develop effective and inclusive approaches to combat this phenomenon.The purpose of the research is to determine the perceptions and propensities of Andean Com
A massive rock/ice avalanche of about 100x106m3 volume took place on the northern slope of the Kazbek massif, North Ossetia, Russian Caucasus, on 20 September 2002.The avalanche started as a slope failure, that almost completely entrained Kolka glacier, traveled down the Genaldon valley for 20km, was stopped at the entrance of the Karmadon gorge, a
This paper investigates the security performance 15-20mmHg of two relay selection schemes for cooperative non-orthogonal multiple access (NOMA) systems, where K randomly distributed relays are employed with either decode-and-forward (DF) or amplify-and-forward (AF) protocols.More particularly, two-stage relay selection (TRS) and optimal relay selec
