With the continuous development of optical fiber access and other network infrastructure, cloud conference, online education, online office, cloud virtual-reality (VR) and other innovative services requiring high bandwidth are widely developed, which puts forward higher requirements on network bandwidth, delay, jitter and stability.Upgrading the le
Several thousands of ozone vertical profiles collected in the course of the MOZAIC programme (Measurements of Ozone, Water Vapour, Carbon Monoxide and Nitrogen Oxides by In-Service Airbus Aircraft) from August 1994 to February 2002 are investigated to bring out climatological and interannual variability aspects.The study is centred on the most freq
This paper constructs a Asian Soup Spoons theoretical model of biased production decisions due to the import of environmental intermediate goods.Additionally, it analyzes the influence of these imports on CO2 emissions based on the trade and CO2 emission data of Chinese prefecture-level cities from 2000 to 2016.Furthermore, it empirically explores
Kisspeptin peptides play major roles in the regulation of reproduction and puberty onset in mammals.While most mammals only have one kisspeptin gene, other jawed vertebrates present two or three genes.Recent data also revealed the presence of two genes in lampreys (jawless vertebrates).However, apart from gene sequence data, there is almost no info
Identifying the small number of rare causal variants contributing to disease has beena major focus of investigation in recent years, but represents a formidable statisticalchallenge due to the rare frequencies with which these variants are observed.In thiscommentary we draw attention to a formal statistical framework, namely hierarchicalmodeling, t
