The existing electronic stability control(ESC)system does not consider the steering intention of an autonomous driving system(ADS)during autonomous driving emergency *** distributed control scheme between ESC and ADS does not involve any information interaction,and the balance between path tracking and lateral stability is not optimal.A Nash game control scheme of steering and braking system is proposed to ensure that both path tracking and stability are simultaneously in the loop and solve the conflict by simulating the interaction between the two agents considering the impact on the interaction between a path following and lateral *** agent considers its interests and the opponent’s interest,resulting in a global optimal control solution of steering control and ***,using minimax optimization theory,a lateral stability strategy is proposed to make the game control architecture under emergency avoidance more robust to uncertain lateral ***,simulation and hardware in the loop experiments show that the proposed scheme can consider both vehicle’s path following performance and lateral stability in the event of an emergency.

Tibetan chicken lives in high-altitude area and has adapted well to hypoxia genetically. Shouguang chicken and Silky chicken are both lowland chicken breeds. In the present study, the complete mito-chondrial genome sequences of the three chicken breeds were all sequenced. The results showed that the mitochondrial DNAs (mtDNAs) of Shouguang chicken and Silky chicken consist of 16784 bp and 16785 bp respectively, and Tibetan chicken mitochondrial genome varies from 16784 bp to 16786 bp. After sequence analysis, 120 mutations, including 4 single nucleotide polymorphisms (SNPs) in tRNA genes, 9 SNPs and 1 insertion in rRNA genes, 38 SNPs and 1 deletion in D-LOOP, 66 SNPs in pro-tein-coding genes, were found. This work will provide clues for the future study on the association between mitochondrial genes and the adaptation to hypoxia.

Globin protein family plays an important role in storing and transporting oxygen. As a newly reported globin, the revealed function of neuroglobin includes binding and storing oxygen as well as facilitating the utilization of oxygen in neuronal cells. In the present study, mutations in exons of chicken Ngb gene were identified with the method of sequencing and created restriction site PCR in Tibet chicken and other four lowland chicken breeds. The mutations of Lys-2224(E4)-Asn and Ser-2279(E4)-Gly were identified in exon 4 of the gene. The Lys-2224(E4)-Asn mutation existed only in Tibet chicken and the mutation frequencies increased with increasing altitude. Analysis of the haplotype and diplotype of the two mutations in Tibet chicken populations of different altitudes showed that the frequencies of TG haplotype and TTGG diplotype also increased with increasing altitude, while the reverse tendency was found on GGAA diplotype. Under the hypoxic simulation incubation, the main haplotype was TG in living embryos and GA in dead embryos. The results showed that the Lys-2224(E4)-Asn mutation may be a specific mutation associated with hypoxia adaptation in Tibet chicken.
