The key advantage of unmanned swarm operation is its autonomous cooperation. How to improve the proportion of cooperators is one of the key issues of autonomous collaboration in unmanned swarm operations. This work proposes a strategy dominance mechanism of autonomous collaboration in unmanned swarm within the framework of public goods game. It starts with the requirement analysis of autonomous collaboration in unmanned swarm;and an aspiration-driven multiplayer evolutionary game model is established based on the requirement. Then the average abundance function and strategy dominance condition of the model are constructed by theoretical derivation. Furthermore, the evolutionary mechanism of parameter adjustment in swarm cooperation is revealed via simulation,and the influences of the multiplication factor r, aspiration levelα, threshold m and other parameters on the strategy dominance conditions were simulated for both linear and threshold public goods games(PGGs) to determine the strategy dominance characteristics;Finally, deliberate proposals are suggested to provide a meaningful exploration in the actual control of unmanned swarm cooperation.

Background： Upon binding luteinizing hormone in the ovary, the luteinizing hormone/choriogonadotropin receptor （LHCGR） is necessary for follicular maturation and ovulation, as well as luteal function. We detected mutations in the LHCGR gene and evaluated their association with superovulation. Methods： Using polymerase chain reaction-single strand sequencing, we examined polymorphisms in LHCGR and Chinese Holstein heifers. conformation polymorphism （PCR-SSCP） and DNA the genotypes associated with superovulation traits in 127 Results： A G/T polymorphism （ss52050737） in exon 11 was significantly associated with the total number of ova and the number of transferable embryos. Conclusions： LHCGR may be a new predictor for superovulation in Chinese Holstein heifers.

Background： The p21-activated kinase 1 （PAK1）is essential of microtubule assembly during oocyte meiotic maturation porcine oocytes. for mitosis and plays an important role in the regulatio in mice; however, little is known about its role in Result： Total p21-activated kinase 1 （PAK1） and phosphorylated PAK1 at Thr423 （PAK1^Thr423） were consistently expressed in porcine oocytes from the germinal vesicle （GV） to the second metaphase （MII） stages, but phosphorylation of histone H3 at Serr10 （H3^ser10） was only expressed after the GV stage. Immunofiuorescence analysis revealed that PAK1Thr423 and H3^ser10 colocalized on chromosomes after the GV stage. Blocking of endogenous PAK1^Thr423 by injecting a specific antibody decreased the phosphorylation level of H3^ser10; however, it had no impact on chromatin condensation, meiotic progression, cleavage rate of blastomeres or the rate of blastocyst formation. Conclusion： Phosphorylation of PAK1^Thr423 is a spontaneous activation process and the activated PAK1^Thr423 can promote the phosphorylation of H3^ser10; however, this pathway is not required for meiotic maturation of porcine oocytes or early embryonic development.

The endometrium of sheep consists of plenty of raised intercaruncular areas （IC）. In order to better understand aglandular areas called caruncular （C）, and intensely glandular the endometrium involved mechanisms of implantation, we used LC-MS/MS technique to profile the proteome of ovine endometrial C areas and IC areas separately during the peri-implantation period, and then compared the proteomic profiles between these two areas. We successfully detected 1740 and 1813 proteins in C areas and IC areas respectively. By comparing the proteome of these two areas, we found 170 differentially expressed proteins （DEPs）（P 〈 0.05）, functional bioinformatics analysis showed these DEPs were mainly involved in growth and remodeling of endometrial tissue, cell adhesion and protein transport, and so on Our study, for the first time, provided a proteomic reference for elucidating the differences between C and IC areas, as an integrated function unit respectively, during the peri-implantation period. The results could help us to better understand the implantation in the ewes. In addition, we established a relatively detailed protein database of ovine endometrium, which provide a unique reference for further studies.

Background： Early pregnancy failure has a profound impact on both human reproductive health and animal production. 2/3 pregnancy failures occur during the peri-implantation period; however, the underlying mechanism（s） remains unclear. Well-organized modification of the endometrium to a receptive state is critical to establish pregnancy Aberrant endometrial modification during implantation is thought to be largely responsible for early pregnancy loss. Result： In this study, using well-managed recipient ewes that received embryo transfer as model, we compared the endometrial proteome between pregnant and non-pregnant ewes during implantation period. After embryo transfer, recipients were assigned as pregnant or non-pregnant ewes according to the presence or absence of an elongated conceptus at Day 17 of pregnancy. By comparing the endometrial proteomic profiles between pregnant and non-pregnant ewes, we identified 94 and 257 differentially expressed proteins （DEPs） in the endometrial caruncular and intercaruncular areas, respectively. Functional analysis showed that the DEPs were mainly associated with immune response, nutrient transport and utilization, as well as proteasome-mediated proteolysis. Conclusion： These analysis imply that dysfunction of these biological processes or pathways of DEP in the endometrium is highly associated with early pregnancy loss. In addition, many proteins that are essential for the establishment of pregnancy showed dysregulation in the endometrium of non-pregnant ewes. These proteins, as potential candidates, may contribute to early pregnancy loss.

A Kalman Filter with Progressive Measurement Update

第37届中国控制会议

作者： zhonghong wu Zhangsong Shi Li Pan Weapon Eng. College Naval Uni. of Engineering Electronics Eng. College Naval Uni. of Engineering

Under the condition of large initial error and/or accurate measurement, due to the decrease of the accuracy of the joint Gauss distribution hypothesis, the moment approximation filtering methods based on Gauss hypothesis have the problem of posteriori error matrix overestimated, which means the error of the filter is much lower than the actual error, resulting in filtering divergence. In view of this problem, a Kalman filter with progressive measurement update is proposed. Firstly, based on Gauss hypothesis, under the framework of Daum-Huang filter, the progressive Bayesian formal description of the state evolution equation is given, the linear Gauss solution of the state evolution equation is derived. Secondly, by means of the first order Taylor expansion, the approximate solution of the nonlinear condition is obtained, and at last a Kalman filter with progressive measurement update and its nonlinear extend form are proposed. Simulation results show that in the large initial error and/or accurate measurement conditions, proposed method improves position estimation accuracy by 90% than UKF（Unscented Kalman Filter） and CKF（Cubature Kalman Filter）, by 17% than EKF（Extended Kalman Filter）, by 30% than similar method when progressive step is 0.1 and by 17% when progressive step is 0.01;proposed method improves velocity estimation accuracy by 66% than UKF and by 73% than CKF, by 53% than EKF, by 23% than similar method when progressive step is 0.1 and equivalent accuracy when progressive step is 0.01.

着舰飞行过程中的轨迹跟踪控制能力是影响舰载无人直升机性能的关键因素,针对无人直升机模型不确定性和在飞行时受阵风干扰的问题,基于扩张状态观测器(extend stated observer,ESO)和动态面策略提出一种应用于无人直升机自主着舰的轨迹跟踪控制方法。首先,建立无人直升机数学模型。其次,设计复合扰动ESO,用来观测未建模动态和外界阵风扰动的影响,并采用前馈补偿的方式来抑制系统不确定性,实现系统对扰动的鲁棒性。然后,采用内外环形式的分层结构设计轨迹跟踪控制器,采取动态面策略避免反步法“微分爆炸”和控制参数调整不敏感的问题,并采用Lyapunov方法证明了整个系统是一致渐进稳定的。最后,采用课题组在研直升机进行了仿真实验,仿真结果表明该控制器具有较好的轨迹跟踪性能。
