| 1 | Resilient Time-Varying Formation-Tracking of Multi-UAV Systems Against Composite Attacks: A Two-Layered Framework显示文摘This paper studies the countermeasure design problems of distributed resilient time-varying formation-tracking control for multi-UAV systems with single-way communications against composite attacks,including denial-of-services(DoS)attacks,false-data injection attacks,camouflage attacks,and actuation attacks(AAs).Inspired by the concept of digital twin,a new two-layered protocol equipped with a safe and private twin layer(TL)is proposed,which decouples the above problems into the defense scheme against DoS attacks on the TL and the defense scheme against AAs on the cyber-physical layer.First,a topologyrepairing strategy against frequency-constrained DoS attacks is implemented via a Zeno-free event-triggered estimation scheme,which saves communication resources considerably.The upper bound of the reaction time needed to launch the repaired topology after the occurrence of DoS attacks is calculated.Second,a decentralized adaptive and chattering-relief controller against potentially unbounded AAs is designed.Moreover,this novel adaptive controller can achieve uniformly ultimately bounded convergence,whose error bound can be given explicitly.The practicability and validity of this new two-layered protocol are shown via a simulation example and a UAV swarm experiment equipped with both Ultra-WideBand and WiFi communication channels. | Xin Gong Michael V.Basin Zhiguang Feng Tingwen Huang Yukang Cui | 2023 | IEEE/CAA Journal of Automatica Sinica2023，10，4： | 1 |
| 2 | Expression of gastrin and cholecystokinin B receptor in Lateolabrax maculatus显示文摘Gastrin(gas)is a peptide hormone that stimulates gastric acid secretion by gastric parietal cells and stimulates gastric motility.The cholecystokinin B receptor(cckbr)can act as a receptor for gastrin,conveying regulatory information on gastrin,but there are fewer studies on its function in fish.The Lateolabrax maculatus is one of the marine aquaculture species in China,it widely distribute in coastal areas.In the study,we cloned the genes of Lateolabrax maculatus gastrin(Lm-gas)and Lateolabrax maculatus cholecystokinin B receptor(Lm-cckbr).The results showed that the full-length gene of Lm-gas is 638bp and the carboxy-terminal conserved domain(DFGRR)is the core functional domain of gastrin protein.The Lm-cckbr gene has a total nucleotide sequence of 2066 bp,and the open reading frame encodes a total of 453 amino acids.The result of protein sequence alignment showed that the similarity between Lm-cckbr protein and other different species was 50.11%-89.67%.The PCR results showed that Lm-gas and Lm-cckbr were expressed in brain and stomach.Further localization by immunehistochemical staining showed that Lm-gas protein was located in the mucosal layer of the gastric wall,but the expression signal was weak in the brain.Hunger causeed a significant decrease in these two genes.The results provided basic research data for further study on the function of Lm-gas and its recepter Lm-cckbr in the in the central nervous system and digestive system of Lateolabrax maculatus. | Tingwen Cui Jiaqi Wang Zhongjun Hu Xiaowu Chen | 2023 | Aquaculture and Fisheries2023，8，5： | 0 |
