摘要： Hong Kong’s young people are encouraged to tap employment and entrepreneurship opportunities on the mainland,thus better integrated into national development.CHINA’S five-star red flag and the regional flag of Hong Kong Special Administrative Region (HKSAR) flew high over Golden Bauhinia Square,with the "Forever Blooming Bauhinia" golden sculpture glittering in the sunshine.It was a solemn occasion at the hall of the Hong Kong Convention and Exhibition Center,where the election of HKSAR’s sixth-term chief executive kicked off at 9:00 a.m.on May 8,2022.

摘要： 毫无疑问,英特尔第12代酷睿处理器的发布给AMD带来了不小的压力,Golden Cove新架构与DDR5内存、Intel 7工艺技术的结合显著提升了英特尔处理器的游戏性能。所以如果要在市场竞争中获得优势,得到消费者更多的青睐,AMD同样需要提升处理器的游戏性能,特别是需要一款能在游戏性能上可以压制第12代酷睿处理器的产品。而在第12代酷睿发布不到半年后,AMD展现了他在设计与制造上的效率,迅速拿出了反击的产品—首款采用3D堆叠三级缓存的AMD处理器:锐龙75800X3D。那么AMD为什么要为处理器配上3D堆叠三级缓存,它的性能表现如何,能否在游戏性能上战胜强劲的第12代酷睿处理器呢?

摘要： Understanding speciation has long been a fundamental goal of evolutionary biology.It is widely accepted that speciation requires an interruption of gene flow to generate strong reproductive isolation between species.The mechanism of how speciation in sexually dichromatic species operates in the face of gene flow remains an open question.Two species in the genus Chrysolophus,the Golden Pheasant(C.pictus)and Lady Amherst’s Pheasant(C.amherstiae),both of which exhibit significant plumage dichromatism,are currently parapatric in southwestern China with several hybrid recordings in field.In this study,we estimated the pattern of gene flow during the speciation of the two pheasants using the Approximate Bayesian Computation(ABC)method based on data from multiple genes.Using a newly assembled de novo genome of Lady Amherst’s Pheasant and resequencing of widely distributed individuals,we reconstructed the demographic history of the two pheasants by the PSMC(pairwise sequentially Markovian coalescent)method.The results provide clear evidence that the gene flow between the two pheasants was consistent with the predictions of the isolation with migration model during divergence,indicating that there was long-term gene flow after the initial divergence(ca.2.2 million years ago).The data further support the occurrence of secondary contact between the parapatric populations since around 30 kya with recurrent gene flow to the present,a pattern that may have been induced by the population expansion of the Golden Pheasant in the late Pleistocene.The results of the study support the scenario of speciation between the Golden Pheasant and Lady Amherst’s Pheasant with cycles of mixing-isolation-mixing,possibly due to the dynamics of geographical context in the late Pleistocene.The two species provide a good research system as an evolutionary model for testing reinforcement selection in speciation.

摘要： 随着单元化方案的普及,越来越多的银行业务也实施了单元化改造。其中银行的代收付业务就可以按照分行所处地域进行单元化拆分,按业务需求使用南北两个数据库集群分别承载业务数据。使用单元化设计可以按分行业务数据进行拆分,减少耦合度,并按照区域就近部署业务,提升业务的响应速度。但单元化设计也给一些全行类的统计查询业务带来不便。业务需要开发专门的归并逻辑,分别从南北两个数据库集群获取数据并做进一步处理,逻辑复杂,并行运算速度慢。

摘要： Southwest China’s Yunnan Province witnessed historic expansion of its coffee industry in the first half of 2022.The average price of raw coffee beans soared to 30 yuan(US$4.2)per kilogram,and the price of coffee reached a historic 10-year high.Exports of raw coffee beans by Yunnan Agricultural Reclamation Coffee Co.,Ltd.expanded 622.81 percent year on year,a new record.Behind the high growth is burgeoning demand in both domestic and international markets.Statistics from the London-based International Coffee Organization(IOC)showed that global coffee consumption grows at an average annual rate of 2 percent,while the growth rate in the Chinese market has reached 15 percent.

摘要： 1.Why Water Biology and Security?Water is an essential natural resource for human survival and development,by providing ecosystem services(drinking water,aquatic foods,transportation,hydropower,biodiversity support).Globally,aquatic foods provide more than 20%of the animal protein for the world's human population,with this percentage reaching 50%in some developing countries(FAO,2020).Aquaculture has been transformed from a farming practice into a modern industry with important contributions to global food security(Gui et al.,2018;Naylor et al.,2021;Golden et al.,2021).

摘要： DEAR EDITOR, Despite the vulnerability of primates to the negative impacts of human activities and climate change, there is still room for optimism. Notably, years of conservation efforts may have paid off for the golden snub-nosed monkey(Rhinopithecus roxellana). Our field surveys confirmed the existence of 188 to 220 wild multilevel societies(MLS) of R. roxellana, with an estimated 22 710 to 26 130 individuals in 2019。

摘要： On an April evening,a golden glow casts down upon the endlessly vast grassland.In the distance,there are flocks after flocks of Tibetan antelopes and wild donkeys sometimes lowering their heads to eat grass and at othertimes dashing off.This is the Changtang National Nature Reserve,which is wellknown as a"no-man’s land"where it is severely difficult for human life to flourish,with the average altitude being more than 5,000 meters.
