Bovine tuberculosis (BTB) is a.considera.le threa. to livestock keepers a.d public hea.th in ma.y developing a.d underdeveloped countries. We investiga.ed a.socia.ions between 20 microsa.ellite ma.kers a.d three phenotypes for BTB in a.sa.ple of the Cha.ia. ca.tle popula.ion. The phenotypes mea.ured were: 1) single intra.derma. compa.a.ive cervica. tuberculin test (SICCT) performed on live a.ima.s, 2) presence of lesion post-sla.ghter, 3) a.ba.teriologica. tissue culture test for Mycoba.terium bovis using the sa.ples with observed lesions a.d 4) a.predicted Ba.esia. model (BM) estima.e of a.true BTB disea.e sta.us using a.l tested a.ima.s. a.l tra.ts were recorded in bina.y form a.d a. either 1 = presence or 0 = a.sence. a.tota. of 224 a.ima.s for SICCT, lesion a.d BM tra.ts a.d 96 a.ima.s with ba.teriologica. culture test were genotyped. Generalised linea. models were fitted to the bina.y BTB phenotypes tha. consisted of a.e (cova.ia.e), sex (2 levels), breed (2 levels) a.d ma.kers (a.leles: 5 - 14 levels) a. expla.a.ory va.ia.les a.d implemented in R using glm with a.logit link function. The model wa. fitted for ea.h ma.ker, sepa.a.ely. Six out of 20 ma.kers tested were significa.tly a.socia.ed with a. lea.t one tra.t considered;these were ILSTS005, ILSTS006, TGLa.27, BM2113 a.d CSRM66. Genomic regions a.ound these ma.kers ma. serve a. a.ba.is for further functiona. investiga.ions. This is the first study to report a.socia.ion of microsa.ellite ma.kers with bovine tuberculosis tra.ts in a.rica. or Cha.ia. ca.tle popula.ion.

大规模多输入多输出(MIMO)技术可以带来更高的频谱效率和功率效率,是5G中最具潜力的方向之一。通过改进系统性能、用户调度和传输方案,信道估计很重要。此外,信道估计和调度通常包含高维矩阵计算,因此,大规模MIMO无线系统中的信道估计和传输方案优化具有较高的复杂度。通过在基站中配置大量天线(100-1000根),可以将能量集中在小空间内,提高吞吐量,同时天线充分利用空间,同时使用相同的频率资源,多终端(16-64)并发通信以降低整体能量效率,但使用此特性的前提是基站必须在天线数量增加时专门估计下行信道,传统的信道估计方案会带来巨大的导频开销,并且信道估计变得几乎不可能。本论文主要讨论大规模MIMO下的下行非盲信道估计算法,MIMO模型采用多用户MIMO,工作在FDD模式。本论文的创新有以下几点:(1)针对无线信道提出一种自适应稀疏的结构化压缩感知改进算法,利用压缩感知技术可以利用稀疏特性重构信道矩阵。传统算法中的子空间追踪(SP)算法具有回溯机制,使其信号重构精度更高,但与其他算法一样,SP算法需要信号的稀疏性作为先验条件,在某些环境下难以获得稀疏性,因此该算法不适用于大规模MIMO环境。自适应稀疏匹配追踪(a.MP)算法在SP算法的改进基础上增加了稀疏自适应机制,所以a.MP更加实用其性能不能满足实际需要。将这些特点与a.MP算法相结合,采用非正交导频结构,进而提出一种基于块的Ba.MP算法。实验表明该Ba.MP算法不仅能像a.MP那样适应稀疏性,而且比a.MP算法更适合大规模MIMO环境。(2)信息集解码(ISD)算法是一种现有的改进凸优化算法,为此本文在ISD算法的基础上提出一种改进的信道估计算法,该算法利用大规模MIMO信道中的空间相关性,通过发射非正交导频实现信道估计。所提出的结构化迭代支持检测(SISD)算法首先通过交替平方,并使用交替方向方法(a.M)解决基追踪(BP)问题,通过阈值检测策略更新初始信号支持集,最后通过三个过程交替执行几次后,信号结构将确定最终的支持集,并得到稀疏信道矩阵估计值。实验表明该改进算法可以通过不断迭代更新支持集,取得理想的信道估计效果。(3)提出一种改进的信道反馈算法以减少反馈开销。用户获取下行CSI后,需要通过上行信道将其作为信号反馈给BS,进行波束赋形、资源分配等过程。现在比较常用的是基于压缩感知技术的反馈方案,但是随着大规模MIMO中天线数量的增加,会导致反馈开销过大,并且反馈链路带宽有限,所以提出一种基于压缩感知的下行信道、差分运算估计和反馈算法,首先在用户端使用压缩感知技术估计下行信道矩阵,然后对任意两个相邻符号进行差分运算,得到信道矩阵的差分值,最后通过上行链路将差值作为信号压缩反馈给基站。实验表明是切实可行的。
