The Effect of Corona Dormancy on the Physiological Stress and Main Nutritional Components in the Transport of Trachinotus ovatus During Survival by Siwei LIU, Jiamei ZHONG, Xiuping FAN, Xiaoming QIN, Jian SHEN, Wenqi XU

“…However, the existing transportation of live fish suffers from various problems such as low survival rate, nutrient loss, and short transportation time due to stress, hypoxia, and water quality deterioration. T. ovatus is a warm temperature-loving, omnivorous migratory fish with high oxygen consumption and vigorous metabolism. …”

Trajectory planning of UUV-assisted UWOC systems based on DQN by Jiawei HU, Xiaoqian LIU, Xinke TANG, Yuhan DONG

“…As a key submarine-based communication platform, unmanned underwater vehicle (UUV) can facilitate underwater wireless optical communication (UWOC).However, fluctuating characteristics of water body, different water qualities, multi-user access present challenges to UUV-assisted UWOC systems, which could be alleviated by an appropriate path planning to maximize the system and each user performance.Deep reinforcement learning (DRL) technology was applied in the path planning of autonomous vehicles, a trajectory planning scheme for UUV-assisted UWOC systems was proposed.The UUV automatically decides the navigation direction through deep Q-network (DQN) method, thereby improving the communication capacity of the system and each user.The impact of distinct water qualities on the capacity enhancement was also investigated.Simulation results suggest that the outputted strategy of DQN can improve the link capacity of the system and each user.This capacity improvement in clear seawater is better than that in pure seawater but lower than that in coastal water.…”

Formation of the River Water Chemistry in the Middle Section of Dousitu River, China by Qian Hui, Li Peiyue, Ding Jia, Yang Chao, Zhang Xuedi

“…The study shows that when a reservoir is built in arid areas, the loss of water resources due to evaporation is huge, which can lead to the degradation of water qualities. Hence, great care should be taken to build a reservoir in arid or semi-arid regions.…”
