A Novel Architecture for Future Classical‐Quantum Communication Networks

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
The standardisation of 5G is reaching its end, and the networks have started being deployed. Thus, 6G architecture is under study and design, to define the characteristics and the guidelines for its standardisation. In parallel, communications based on quantum‐mechanical principles, named quantum communications, are under design and standardisation ...

The effects of the ratio of pellets of wheat and barley grains to ground corn grain in the diet on sorting and chewing activities of heat stressed dairy cows

Veterinary Medicine and Science, Volume 7, Issue 4, Page 1409-1416, July 2021., 2021
Heat stressed dairy cows fed diets with different ratio of grains. Increasing barley and wheat grain ratio motivated cow to sort against long particles A more fluctuation in daily eating behaviour was also observed with the increasing of the grain ratio.

A two‐branch network with pyramid‐based local and spatial attention global feature learning for vehicle re‐identification

CAAI Transactions on Intelligence Technology, Volume 6, Issue 1, Page 46-54, March 2021., 2021
Abstract In recent years, vehicle re‐identification has attracted more and more attention. How to learn the discriminative information from multi‐view vehicle images becomes one of the challenging problems in vehicle re‐identification field. For example, when the viewpoint of the image changes, the features extracted from one image may be lost in ...
