A new algorithm for the stabilization or (possibly turbulent, chaotic) distributed systems,governed by linear or non linear systems of equations is *** SPA (Stabilization Parallel Algorithm) is based on a systematic parallel decompositionof the problem (related to arbitrarily overlapping decomposition of domains) and on a *** is presented here for the case of linear parabolic equations, with distributed or boundarycontrol. It extends to practically all linear and non linear evolution equations, as it will bepresented in several other publications.

The aim of this study was to correlate plumage variation with the amount of genomic hybrid content in hybrids between Azure Tits Cyanistes cyanus(Pallas,1770)and European Blue Tit Cyanistes caeruleus(Linnaeus,1758),by re-sequencing the genomes of museum specimens of non-hybrids and presumed hybrids with varying *** project was funded by crowdsourcing and initiated when two presumed Azure Tits,observed by hundreds of Swedish birdwatchers,were rejected as hybrids based on minor plumage deviations assumed to indicate hybrid contents from the European Blue *** results confirm that hybrids with intermediate plumages,so called Pleske’s Tits,are first generation hybrids(F1 hybrids).Individuals,whose plumages are similar to Azure Tits,but assessed as hybrids based on minor plumage deviations,are all backcrosses but vary in their degree of hybrid ***,some individuals morphologically recognized as pure Azure Tits expressed similar degrees of hybrid *** results indicate that:(1)hybrid content may be widespread in Azure Tits in the western part of its habitat distribution;(2)plumage deviation in backcrosses is not linearly correlated with the genetic degree of hybrid origin;and(3)all Azure Tits observed in Europe outside its natural distribution may have some degree of hybrid *** therefore suggest that it is very difficult to phenotypically single out hybrids beyond first generation *** argue that decreased sequencing costs and improved analytical tools open the doors for museomic crowd-sourced projects that may not address outstanding biological questions but have a major interest for lay citizens such as birdwatchers.

综合三维地震、钻井、岩心和薄片资料分析了该油藏的储层展布格架、油藏构造及演化、油藏类型和控制因素等。在钻井剖面对比图上依据密度和中子测井 ,将白云岩储层可划分为 4个小层。第 1、2小层由于位于圈闭构造的较高部位因而通常含油。第 3、4小层可能由于在某处与第 1、2小层连通 ,虽然也具低幅度构造和更大的厚度及孔隙度 ,但多为水层 ;又因其容易侧向尖灭 ,故有可能形成地层圈闭。　　三维地震解释和正演模型均表明 ,当第 1、2小层较厚时 ,常对应于强振幅和高频反射 ;当第 3、4小层较厚且 4个小层并存时会在原储层反射位置下方多出一个波峰同相轴 ,而且第 3、4小层的尖灭通常伴随着该同相轴的终止。这一点有助于寻找与第 3、4小层上倾尖灭有关的圈闭。Midale油藏的空间分布受局部低幅度构造和储层小层发育状况的双重控制。油藏驱动机制可能为边水和底水两种类型的结合。根据地震剖面上的地层关系和由三维地震资料所做的古构造演化图来看 ,油藏低幅度构造的形成与后期地层在前寒武基岩古隆起上的披覆及该隆起在后期多次不整合发生期间的重新活动有关。圈闭雏形形成于早志留到中泥盆世 ,最终定型于晚白垩世。区域构造演化和油气运移研究表明 ,有利的油气聚集带位于某些靠近油源区的古鼻隆的东北翼。

Whole-genome duplications are an important source of evolutionary novelties that change the mode and tempo at which genetic elements evolve within a genome. The Cucurbita genus experienced a wholegenome duplication around 30 million years ago, although the evolutionary dynamics of the coding and noncoding genes in this genus have not yet been scrutinized. Here, we analyzed the genomes of four Cucurbita species, in eluding a newly assembled genome of Cucurbita argyrosperma, and compared the gene con tents of these species with those of five other members of the Cucurbitaceae family to assess the evolutionary dynamics of protein-coding and long intergenic noncoding RNA (lincRNA) genes after the genome duplication. We report that Cucurbita genomes have a higher protein-coding gene birth-death rate compared with the genomes of the other members of the Cucurbitaceae family. C. argyrosperma gene families associated with pollination and transmembrane transport had significantly faster evolutionary rates. lincRNA families showed high levels of gene turnover throughout the phylogeny, and 67.7% of the lincRNA families in Cucurbita showed evidence of birth from the neofunctionalization of previously existing protein-coding genes. Collectively, our results suggest that the whole-genome duplication in Cucurbita resulted in faster rates of gene family evolution through the neofunctionalization of duplicated genes.

有时候我们看到照片上的某台车辆,心中就会燃起强烈的制作欲望,所以我第一次见到这台用橡胶垫当作附加装甲的塞尔维亚军M36杰克逊坦克歼击车时就被深深吸引住了。该车的外形怪异,相信有些人喜欢,有些人则觉得丑爆了。对我而言它不仅在外观上吸引了我,如何重现这种大刀阔斧的改造也是一项有趣的挑战,特别是到了涂装和旧化环节,怎样表现橡胶这种有趣的材料也是一大难题。重要的是,我们要仔细揣摩实物图片,观察其表面历经风吹日晒的外观,并善用手中的涂料将其生动地表现出来。
