Previous studies have shown that octamer-binding transcription factor 4（Oct4） plays a significant role in early embryonic development of mammalian animals, and different Oct4 expression levels induce multi-lineage differentiation which are regulated by DNA methylation. To explore the relationship between the methylation pattern of Oct4 gene exon 1 and embryonic development, in this work, five different tissues（heart, liver, lung, cerebrum and cerebellum） from three germ layers were chosen from low age（50–60 d） and advanced age（60–70 d） of fetal cattle and the differences between tissues or ages were analyzed, respectively. The result showed that the DNA methylation level of Oct4 gene exon 1 was significant different（P〈0.01） between any two of three germ layers in low age（〈60 d）, but kept steady of advanced age（P〉0.05）（〉60 d）, suggesting that 60-d post coital was an important boundary for embryonic development. In addition, in ectoderm（cerebrum and cerebellum）, there was no significant methylation difference of Oct4 gene exon 1 between low age and advanced age（P〉0.05）, but the result of endoderm（liver and lung） and mesoderm（heart） were on the contrary（P〈0.01）, which indicated the development of ectoderm was earlier than endoderm and mesoderm. The methylation differences from the 3rd, 5th and 9th Cp G-dinucleotide loci of Oct4 gene exon 1 were significantly different between each two of three germ layers（P〈0.05）, indicating that these three loci may have important influence on bovine embryonic development. This study showed that bovine germ layers differentiation was significantly related to the DNA methylation status of Oct4 gene exon 1. This work firstly identified the DNA methylation profile of bovine Oct4 gene exon 1 and its association with germ layers development in fetus and adult of cattle. Moreover, the work also provided epigenetic information for further studying bovine embryonic development and cellular reprogramming.

分组密码的安全性主要依赖于S盒(向量值密码函数)的各项安全性指标.分组密码S盒的最优选择就是差分均匀度为4的向量值密码函数.逆函数是最著名的差分均匀度为4各项安全性指标均优良的向量值函数.著名的AES分组密码算法、Camellia分组密码算法、CLEFIA分组密码算法和SMS4分组密码算法均采用有限域F2.上与逆函数仿射等价的向量值函数作为S盒.目前对于与逆函数仿射等价S盒的研究,主要侧重于研究分组密码算法经过多轮后活跃S盒的数量.与以往的研究角度有所不同,该文要研究有限域F_(p^n)上与逆函数仿射等价向量值密码函数的计数问题.若能计算出与逆函数仿射等价密码函数的数量,在实际应用中就知道有多少个与逆函数仿射等价的S盒可供算法设计者选择.将有限域F_(2.n)上的逆函数推广成有限域F_(p^n)上的逆函数,其中p≥2.一个素数,这是一个更为一般的逆函数.首先,该文定义(T_1,R_1)和(T2.R_2.之间的运算"*"为(T2.R_2.*(T_1,R_1)··=■,其中(T_1,R_1),(T2.R_2.∈Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q),Aff_n^(-1)(F_q)是有限域F_q上的n×n阶可逆仿射变换群,q=p^m,p≥2.一个素数,m≥1是一个正整数,"■"表示映射的合成.证明了Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)关于运算"*"是一个群;使得等式F=■成立的可逆仿射变换对(V,W)∈Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)关于运算"*"是Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)的一个子群.然后,利用以上结论和有限域的一些性质证明了,当p≥3且n≥2.,或者p=2.n≥4时,对于有限域F_(p^n)上的逆函数F(x)=x^(-1)=x^(p^n-2.,使得等式F=■成立的可逆仿射变换μ和ν线性化多项式的形式只能是μ(x)=S_tx^(p^t)和ν(x)=S_t^(p^n-t) x^(p^n-t),0≠St∈F_(p^n),t=0,1,…,n-1.于是,使得等式F=■成立的所有可逆仿射变换对(ν,μ)的数量为n(p^n-1).利用这些可逆仿射变换对(ν,μ)所形成的子群对群Aff_n^(-1)(Fp)×Aff_n^(-1)(Fp)划分等价类,商集中陪集首的个数即为与逆函数仿射等价密码函数的数量.因此,在这种情况下,与逆函数仿射等价密码函数的数量为■.最后,当p=2.n=3时,对于有限域F_2.3上的逆函数F(x)=x^(-1)=x^(2.3-2.,利用计算机作为辅助手段测试出使得等式F=■成立的可逆仿射变换对(ν,μ)的数量为168.利用这些可逆仿射变换对(ν,μ)所形成的子群对群Aff_3^(-1)(F2.×Aff_3^(-1)(F2.划分等价类,商集中陪集首的个数即为与逆函数仿射等价密码函数的数量.因此,在这种情况下,与逆函数仿射等价密码函数的数量为10 752.研究结果表明,在实际应用中,有限域F2.8上有■个与逆函数仿射等价的密码函数可作为分组密码的S盒使用.

黄铁矿作为页岩体系中最具代表性的重矿物之一,对其进行微观特征识别对于页岩沉积环境研究具有重要意义。以四川盆地泸州I区五峰组一龙一,亚段为例,通过岩心矿物实验、扫描电镜观测、网络模型优化和特征参数统计,构建了适用于黄铁矿扫描电镜图像分割的网络模型,实现了基于草莓状黄铁矿参数对研究区沉积环境的判断。结果表明:①优化后的UNet-Im模型对草莓状黄铁矿扫描电镜图像的分割精度可达0.863,证明了改进措施的优越性;②对比黄铁矿含量,龙一^(1-3)_(1)小层黄铁矿含量最高,为2.95%,随后降低至龙一^(4)_(1)小层的2.03%以及五峰组的0.83%;③基于草莓状黄铁矿特征参数,推断出黄铁矿沉积环境为深水硫化环境、深水强还原环境、深水强一弱还原环境以及深水还原一次氧化环境。实现了黄铁矿扫描电镜图像的精准化分割,对于提升行业勘探开发智能化具有借鉴意义。

在如今的数据中心中,各种分布式任务往往会对各种不同的资源进行竞争,特别是网络资源.如果没有有效的网络调度,那么这种竞争就会降低整个数据中心的运行效率.以往的网络资源调度研究由于忽视了任务里计算与网络需求之间的具体关系,对于任务性能的提升十分有限.因此,旨在探索如何通过网络调度来缩短数据中任务的完成时间(job completion time,JCT),从而提升数据中心的整体效率.通过对基于有向无环图(directed acyclic graph,DAG)的分布式任务的深度分析,发现可以在降低它们的网络占用的同时,却不影响它们的JCT.根据这个发现,提出了一个利用计算图来加速任务执行的网络调度器JIT.为了实现JIT,首先将调度问题建模成为一个整数线性规划问题(integer linear programming,ILP),然后证明了这个ILP可以通过一个等价的线性规划模型(linear programming,LP)来快速求解.此外,通过一些合理的简化,将求解时间降低到了1 s.与其他调度器的比较实验结果说明了JIT可以取得1.55倍的整体加速效果,从而有效提升数据中心的工作效率.

量子同态加密对量子态密文直接进行同态评估计算,而不是将密文解密之后再进行计算.基于相位和状态变换的d维通用酉算子,提出了一种d维(t,n)门限量子同态加密算法.在该算法中,客户端将量子态密文传送给n个服务器中的t个,这t个服务器生成评估子密钥,运行评估算法对量子态密文执行同态计算.客户端对解密之后的量子态执行CNOT门操作,t+1个粒子的聚合值就是评估算法对量子态明文计算之后的结果.该算法使用Shamir(t,n)门限机制隐藏了评估密钥,保护了客户端的隐私数据.从理论上证明了算法的正确性,各个阶段操作过程的仿真实现进一步验证了算法的正确性.
