Research on SSB 1+X beam technology of 5G network by Bei LI, Yuhua HU, Xinyan WANG, Guoping XU, Guanghai LIU, Tian XIAO, Chen CHENG, Yi LI

“…Beam scanning and spatial dimensions in 5G was introduced in the 3GPP standard.When UE connects gNodeB, gNodeB uses SSB beam rotation to detect the optimal beam of UE.After UE was connected, the CSI-RS configuration information could be obtained and the CSI could be normal feedback，gNodeB adopted the optimal beam transmitted by the CSI-RS beam in turn.5G antennas flexibly configure the number of beams and take into account coverage in both horizontal and vertical dimensions.The development of broadcast beams and the horizontal 7 beams facing challenges were presented, the horizontal 7 beam and 1+X beam schemes were analyzed.Finally, efficiency was presented.…”

Physical layer security for the air-space-ground communication networks by Shuai HAN, Xiangxue TAI, Weixiao MENG

“…As a typical application of wireless communications,the air-space-ground communications networks are facing serious wireless communications security issues due to its inherent broadcast nature and wide coverage.Especially in the field of military satellite communications,the requirement of secure communications security is even more crucial.How to realize the security of communications is a problem must be faced.A model for physical layer security communication in air-space-ground communication network was proposed which was a cooperative layer-direct connect mixed-to-ground physical layer secure communication model.Based on this model,the security of the system was further improved by studying the relay selection problem and the power distribution problem of satellite and relay,and an overall scheme to enhance the confidentiality of the communication network was also proposed.…”

Strategy of routing based on layered for underwater wireless sensor networks by Jian PENG, Chang-jian HONG, Tang LIU, GYun-yong ZHAN

“…A layered-depth based routing protocol was proposed for underwater wireless sensor networks (layered-DBR). After nodes broadcast, message only could be received by nodes in predefined depth in order to control the copies of message and finally a network hierarchy model related to redundancy could be built. …”

Challenges of political communication with young people on social media by A. A. Komarova

“…In the course of the study, it was important to find out not only which communication and information channels influence the formation of political opinions of modern youth, but also how young people participate in public discussion of topical issues, with the help of which online resources they broadcast their point of view. In order to create effective communication with the youth audience, including in the field of political topics, attention should be paid to how media personalities who are attractive to young people and who can shape the moods and orientations of modern young people form their content, how they communicate, how they convey information.…”

Self-healing group key distribution scheme with revocation based on dual directional hash chain by DU Chun-lai1, HU Ming-zeng2, ZHANG Hong-li2, ZHANG Dong-yan2

“…A self-healing group key distribution scheme with revocation in MANET using dual directional hash chain was proposed.The association relation between different session keys was built.By means of broadcast information and own secrets,the legal nodes which lost some legal session keys due to network faults could be capable of recovering such lost session keys on their own,without requiring additional transmission from the group manager.The group manager could revoke the group nodes by revocation polynomial.Node was endowed with a set of masking secret according to its life-cycle.Through the security and efficiency analysis,the key distribution scheme reduces communication cost and storage cost yet still achieves security property.…”

Aide-toi, la viralité t’aidera. Ou de la création et diffusion des proverbes dans les médias by Vincenzo Lambertini

“…Thus, I will compare proverbs and virality through contrasting (French-Italian) and interdisciplinary (from biology and virology) approaches, using authentic examples drawn from social media and semi-spontaneous conversations broadcast on radio or television. This study will show not only that virality and proverbs share many features, but also that proverbs can adapt to new realities (which may allow them to evolve in the future without disappearing). …”

Evolution by natural selection is a scientific law and not just a theory by Daniel J.M. Crouch, Walter F. Bodmer

“…The developing knowledge of prokaryotic microorganisms and the discovery of DNA or RNA as the fundamental basis of inheritance in all living organisms, together with Mendel’s laws, now provide the four basic conditions for evolution by natural selection, namely reproduction that is stable, but allows for variation that can increase fitness in the broadest sense. These definitive conditions establish an exponential growth law for evolution by natural selection that applied initially for the longest period of time to the evolution of asexual clonal organisms, and through Mendel's laws, extends to bisexual multicellular organisms. …”
