基于用户所特有的击键节奏特征,提出了一种判别某一击键序列是否为某特定用户的行为的方案。该方案利用非参数方法中的Spearman 相关分析来确定计算 cityblock 距离所需的权值,进而利用预存样本与新输入样本之间的距离来判定用户的身份。所以此方案不受各种可能击键的概率分布限制。一个基于击键特征的用户身份校验系统已经使用 Java 语言成功地实现。

什么是黑洞?这个问题颇难回答.对于普通大众来说,黑洞是一种在科幻题材中经常出现的奇怪天体.而对于相关的研究人员来说,黑洞是时空中连光都逃脱不出的区域,在宇宙中实实在在的存在.虽然认识的水平有所不同,但黑洞这个物理对象对他们来说都是神秘的,神秘到至今为止我们也不能够真正地理解它.如果人们再追问:黑洞的本质是什么?不同的人也许有不同的理解.甚至有时候从事黑洞物理研究的学者们所给出的答案也会大相径庭.本文不试图给出博人眼球的解答,而是倾向于告诉读者学术界关于这一问题的主流理解方式.

Amylose content(AC) is the main factor determining the palatability, viscosity, transparency, and digestibility of rice(Oryza sativa)grains. AC in rice grains is mainly controlled by different alleles of the Waxy(Wx) gene. The AP2/EREBP transcription factor OsEBP89 interacts with the MYC-like protein OsBP5 to synergistically regulate the expression of ***, we determined that the GLYCOGEN SYNTHASE KINASE 5(OsGSK5, also named SHAGGY-like kinase 41 [OsSK41]) inhibits the transcriptional activation activity of OsEBP89 in rice grains during amylose biosynthesis. The loss of OsSK41 function enhanced Wx expression and increased AC in rice grains. By contrast, the loss of function of OsEBP89 reduced Wx expression and decreased AC in rice grains. OsSK41 interacts with OsEBP89 and phosphorylates four of its sites(Thr-28,Thr-30, Ser-238, and Thr-257), which makes OsEBP89 unstable and attenuates its interaction with OsBP5. Wx promoter activity was relatively weak when regulated by the phosphomimicvariantOsEBP89E–OsBP5but relatively strong when regulated by the nonphosphorylatable variant OsEBP89A–***, OsSK41-mediated phosphorylation of OsEBP89 represents an additional layer of complexity in the regulation of amylose biosynthesis during rice grain development. In addition, our findings provide four possible sites for regulating rice grain AC via precise gene editing.

Auxin is an important phytohormone in plants, and auxin signaling pathways in rice play key roles in regulating its growth, development, and productivity. To investigate how rice grain yield traits are regulated by auxin signaling pathways and to facilitate their application in rice improvement, we validated the functional relationships among regulatory genes such as OsIAA10, OsSK41, and OsARF21 that are involved in one of the auxin(OsIAA10) signaling pathways. We assessed the phenotypic effects of these genes on several grain yield traits across two environments using knockout and/or overexpression transgenic *** on the results, we constructed a model that showed how grain yield traits were regulated by OsIAA10 and OsTIR1, OsAFB2, and OsSK41 and OsmiR393 in the OsSK41-OsIAA10-OsARF module and by OsARF21 in the transcriptional regulation of downstream auxin response genes in the OsSK41-OsIAA10-OsARF module. The population genomic analyses revealed rich genetic diversity and the presence of major functional alleles at most of these loci in rice populations. The strong differentiation of many major alleles between Xian/indica and Geng/japonica subspecies and/or among modern varieties and landraces suggested that they contributed to improved productivity during evolution and breeding. We identified several important aspects associated with the genetic and molecular bases of rice grain and yield traits that were regulated by auxin signaling *** also suggested rice auxin response factor(OsARF) activators as candidate target genes for improving specific target traits by overexpression and/or editing subspecies-specific alleles and by searching and pyramiding the ‘best' gene allelic combinations at multiple regulatory genes in auxin signaling pathways in rice breeding programs.

The distribution of rice blast-resistant genes Pi2, Pi5, Pi9, Pi54, Pia, Pib, Pit and Pita in 36 restoring lines and 42 sterile lines were detected using functional molecular markers. The results indicated that those eight blast-resistant genes distributed in the 78 tested lines at various frequencies. Six rice blast-resistant genes were detected in the sterile line Shen 11 A, containing the most rice blast-resistant genes among the 78 lines, whereas no rice blast-resistant gene was detected in the lines 8527 A, Xu1 A and 016 A. The genetic distance-based clustering analysis showed that those 78 lines could be divided into five groups.
