Let X be a finite simple undirected graph and G an automorphism group of X. If G is transitive on s-arcs but not on （s ＋ 1）-arcs then X is called （G, s）-transitive. Let X be a connected （G, s）-transitive graph of a prime valency p, and Gv the vertex stabilizer of a vertex v E V（X） in G. For the case p = 3, the exact structure of Gv has been determined by Djokovid and Miller in [Regular groups of automorphisms of cubic graphs, J. Combin. Theory （Ser. B） 29 （1980） 195-230]. For the case p = 5, all the possibilities of Gv have been given by Guo and Feng in [A note on pentavalent s-transitive graphs, Discrete Math. 312 （2012） 2214-2216]. In this paper, we deal with the case p = 7 and determine the exact structure of the vertex stabilizer Gv.

作者： li yantao Xiao Di Deng Shaojiang College of Computer Science Chongqing UniversityChongqing 400044P.R.China

A new algorithm for a novel hash function, based on chaotic tent map with changeable parameter, is proposed and analyzed. The one dimensional and piecewise tent map with changeable parameters decided by the position index of blocked messages is chosen, and blocked massages translated into ASCII code values are employed as the iteration time of the chaotic tent map. The final 128-bit hash value is generated by logical XOR operation on intermediate hash values. Theoretical analysis and computer simulation indicate that the proposed algorithm can satisfy the performance requirements of hash function.

利用Illumina NovaSeq高通量测序、冗余分析和FUNGuild等方法对甘肃金徽酒10a和50a窖龄窖池及其不同空间位置窖泥的真菌群落结构、真菌菌群与理化因子之间的关系以及真菌功能预测等进行研究。结果表明,随着窖池深度的增加,10 a窖池窖泥的多样性和丰富度呈现降低趋势,50 a窖池窖泥的多样性整体呈现升高趋势,而丰富度则呈现先降低后升高趋势,其中10a窖池窖壁上层的多样性和丰富度均显著高于其他位置(P<0.05),而50a窖池窖底层的多样性和丰富度均显著高于其他位置(P<0.05)。10a窖池窖壁层的多样性和丰富度显著高于50a窖池(P<0.05),而50a窖底层的多样性和丰富度明显高于10a窖池(P<0.05)。所有窖泥样品共检测到21个真菌门和520个真菌属,其中子囊菌门(Ascomycota)、担子菌门(Basidiomycota)、被孢霉门(Mortierellomycota)和罗兹菌门(Rozellomycota)4个优势真菌门以及曲霉属(Aspergillus)和哈萨克斯坦酵母属(Kazachstania)等多数优势真菌属的相对丰度随窖池窖龄和空间位置的变化差异显著(P<0.05)。镰刀霉属(Fusarium)、Aspergillus、Kazachstania和红曲霉属(Monascus)与水分、腐殖质、K^(+)和Ca^(2+)含量呈正相关,枝孢菌属(Cladosporium)、维希尼克氏酵母属(Vishniacozyma)与pH值呈正相关。窖泥真菌营养类型主要有腐生营养型和病理-腐生-共生营养型等7种,功能类群包括4个单一功能群和7个混合功能群。通过系统分析不同窖龄窖池和空间位置的窖泥真菌群落多样性,为明确甘肃金徽酒窖泥的真菌群落结构及空间分布规律奠定了理论基础。

类固醇糖尿病(SDM)是由于体内糖皮质激素过多引起的一种糖代谢紊乱综合征。相比于常见的2型糖尿病并发糖尿病足溃疡(DFU),类固醇相关DFU患者因其体内长期糖皮质激素过多,其皮肤萎缩、皮肤屏障作用被严重削弱、机体免疫力明显下降、机会菌或者真菌感染进一步增加,患者创面愈合难度更大,致死率、致残率更高。该文报道了2例类固醇相关DFU患者,旨在提高临床医师对DFU患者明确糖尿病分型的重视,警惕SDM。对于类固醇相关DFU患者,围术期需进行糖皮质激素补充,术后糖皮质激素替代应个体化,了解类固醇相关DFU创面处理的复杂性。
