The mudstone, gray tuffite and carbonaceous shale in the Upper Carboniferous Batamayineishan Formation（Bashan Formation） are essential source rocks for the volcanic reservoir in eastern Junggar, northwestern China. The kerogen components, vitrinite reflectance, Rock-Eval pyrolysis, lipid biomarkers and isotope compositions were measured to understand the provenance and depositional environment of Bashan Formation under the background of volcanic activities. There were 10 and 4 periods of volcanic eruptions identified in the wells CS and DZ, respectively. The source rocks developed in the late or intermittent phase of volcanic activity. The original island arcs of the Early Carboniferous evolved into the Wucaiwan sag and the Dishuiquan sag in the Bashan Formation. The Wucaiwan sag inherited the restricted, closed residual sea, which had a slightly anoxic and hypersaline environment. The Dishuiquan sag was generally an oxidizing lacustrine environment, influenced by a marine transgression that may have occurred at the end of the DZⅢperiod during the Late Carboniferous. Although the total organic matter decreased due to the volcanic eruption, ash could cause an increase of aquatic organisms, coinciding with increases in salinity and reducibility in the Dishuiquan sag.

Background: Phylogeographical patterns and population dynamics are usually interpreted by environmental disturbances and geographic barriers of the past. However, sister species may exhibit disparate patterns of genetic structures and population dynamics due to their habitat preference and altitude segregation. In this study, we tested how species-specific altitude habitat affected phylogeographical patterns in two sister snowcock species, Tibetan(Tetraogallus tibetanus) and Himalayan Snowcocks(T. himalayensis).Methods: A panel of seven microsatellite loci and a fragment of Mitochondrial DNA Control Region were used to investigate genetic structures and population dynamics in hope of revealing the underlying evolutionary processes through the identification of possible past demographic ***: Our results suggest that T. himalayensis showed a significant phylogeographical signal in mtDNA(FST microsatellite(F the glacial-interglacial cycles in the = 0.66, p < 0.001) and ST Pleistocene and followed demog= 0.11, p < 0.001) data and is stable duringraphic contraction until 0.003 million years(Mys) ago. The phylogeographical signal of T. tibetanus is lower than the level of genetic difference among populations in mtDNA(FST icrosatellite(F= 0.41, p < 0.001) and mST s been experien= 0.09, p < 0.001) data, likely benefiting from stable habitats over a long period of time.

Background: In birds, the trade-off between the quality and number of nestlings is one of the most important theories of the evolution of life history of birds, which is closely related with climate. We investigated variation in egg and clutch size of the Black Redstart(Phoenicurus ochruros) on the northeastern edge of the Qinghai-Tibetan Plateau in order to explore and test the relation between egg size and clutch size and the rules governing the variation in these two components with climate ***: We monitored each located nest daily to determine the exact laying order of the eggs and measured their sizes. The variations in egg volume and clutch size between 2008 and 2009 were studied by independent sample t tests. The difference in egg volume in the sequence of the laying order was tested by Kendall's W test and we employed Pearson correlations to investigate the relation between egg size and laying order. All statistical analyses were performed with IBM SPSS Statistics, version 19.0Results: In 2008, the mean egg volume of the Black Redstart was 2.40 and clutch size wer± 0.20 cm^3(n e 2.26 = 50), and the mean clutch size 4.90 ± 0.57(n = 11). In 2009, the mean egg volumeation between eg± 0.18 cm^3(n g size and layin= 74) and 5.20 g order(r ± 0.26(n = 15) respectively. We found a significantly positive correl, while egg size was strongly and negatively correlated with clutch size(r = 0.397, p = 0.030) smaller eggs but a larger clutch in a brood in a resource-rich year, w= h-0.274, p ereas large= 0.002). Black Redstarts tend to layr eggs but smaller clutches are produced in a harsh ***: The Black Redstart adopted a "brood survival strategy" to ensure that more offspring could survive. The Black Redstart' trade-off in egg volume and clutch size would guarantee that it will gain maximum benefit in any case.

Himalayan snowcock Tetraogallus himalayensis are distributed in alpine and subalpine areas in China. We used mi- tochondrial DNA control-region data to investigate the origin and past demographic change in sixty-seven Himalayan snowcock T. himalayensis. The fragments of 1155 nucleotides from the control region of mitochondrial DNA were sequenced, and 57 poly- morphic positions defined 37 haplotypes. A high level of genetic diversity was detected in all populations sampled and may be associated isolation of the mountains and habitat fragmentation and deterioration from Quaternary glaciations. In the phylogenetic tree, all haplotypes grouped into four groups： clade A （Kunlun Mountains clade）, clade B （Northern Qinghai-Tibetan Plateau clade）, clade C （Tianshan Mountains clade） and clade D （Kalakunlun Mountains clade）. We found a low level of gene flow and significant genetic differentiation among all populations. Based on divergence time we suggest that the divergence of Himalayan snowcock occurred in the middle Pleistocene inter-glaciation, and expansion occurred in the glaciation. Analysis of mtDNA D-loop sequences confirmed demographic population expansion, as did our non-significant mismatch distribution analysis. In conclusion, limited gene flow and a pattern of partial isolation phylogeographic was found in geographic populations of T. hima- layansis based on the analysis on mtDNA D-loop sequences [Current Zoology 57 （6）： 758-767, 2011].

工业企业是能源消费大户,对工业用电量进行短期预测既有助于电力系统及时进行能源调度和平衡管理,也有利于工业企业优化生产计划和能源结构,提高能源利用率。然而,随着信息安全和数据保护要求的不断提高,现有的集中训练预测模型面临着无法获取大量用户数据的问题。基于云边协同系统架构,提出了一种结合联邦学习框架和长短期记忆神经网络的方法应用于工业企业电能消耗预测,旨在实现数据隐私保护和准确预测的目标。根据五个不同工业企业电能消耗数据的实验结果,该方法表现出较强的泛化能力,其整体预测的平均绝对百分比误差结果优于多个现有深度学习模型,在不共享原始数据的情况下,实现了更高效的数据处理和模型训练。
