Airborne system is developing towards the direction of integration, intelligence and automation. The integration of the system is usually realized by the way of cross-linking of the system. The cross-linking relationship among systems is complex, and the number of cables is large, which can increase the complexity of the whole airborne system. Requirements for hardware resources of the airborne system are very high, and the contradiction between the high demand for the integrated airborne system and the slow upgrade speed of hardware resources appears. The demands for intelligent airborne systems are also developed. A distributed cloud-edge-terminal intelligent architecture for airborne system is proposed, which combines cloud-edge-terminal technology, distributed network control technology and distributed integrated modular avionics system technology. The architecture is reasonably constructed through cloud management platform, edge control platform and terminal platform, and is configured with high-speed secure real-time network and container software technology. The architecture proposed in this paper can increase the degree of integration of the multi-aircraft airborne system while without increasing the whole aircraft complexity. The architecture can meet the requirement of the new technologies application such as artificial intelligence, information fusion, large data processing, and the expansion of new functions.

Population size is a critical indicator used to assess the demographic profile and conservation status of animal species living in disturbed habitats. Using GIS technology, we calculated the remaining habitat area and estimated the population size of the Guizhou snub-nosed monkey (Rhinopithecus brelichi), an Endangered primate endemic to China. The last remaining population of this species resides in the Fanjingshan National Nature Reserve (FNNR). We combined data on forest cover and patterns of group movement to estimate the size and continuity of their habitat. The results indicated that the area of remaining suitable habitat is 69.6 km2. However the monkeys are confined to an area of only 27.8 km2 (6.6% of the total reserve area of 419 km2) located in the northern part of the reserve. The remaining 28.5 km2 of suitable habitat is located in the southern part of the reserve and inaccessible to the monkeys because of the recent construction of an aerial tram. Based on estimates of population density, we calculated that the remaining world’s population of R. brelichi is approximately 125–336 individuals. In order to protect this species from extinction, we recommend that the highly fragmented evergreen and deciduous broadleaf mixed forest adjacent to the remaining troop’s home range be given protected status and an active program of forest regeneration in this area be implemented immediately.

Ecological factors are known to influence the activity budgets of Yunnan snub-nosed monkeys (Rhinopithecus bieti). However, little is known about how activity budgets vary between age/sex classes, because the species is difficult to observe in the wild. This study provides the first detailed activity budgets subdivided by age/sex classes based on observations of the largest habituated group at Xiangguqing in Baimaxueshan Nature Reserve. This study was conducted from June 2008 to May 2009. We found that adult females spent more time feeding (44.8%) than adult males (39.5%), juveniles (39.1%), and infants (14.2%). Adult males allocated more time to miscellaneous activities (12.5%) than did adult females (3.8%). Infants were being groomed 6.9% of the time, which was the highest proportion among all age/sex classes. Adults spent more time feeding, while immature individuals allocated more time to moving and other activities. There are several reasons activity budgets may vary by age/sex class: 1) differential reproductive investment between males and females; 2) developmental differences among the age categories; 3) social relationships between members of different age/sex classes, particularly dominance. In addition, group size and adult sex ratio may also impact activity budgets. These variations in activity budgets among the different age/sex classes may become a selective pressure that shapes the development and growth pattern in this species.

As traditional drivers fade, cultivating new drivers has become the key to the high-quality development of China’s economy. In the new round of scientific and technological revolution and industrial transformation, the digital economy plays a strategic role in promoting high-quality economic development in China, by using data as a new key production factor and innovation as the driving force, and driving impetus change, efficiency change and quality change to increase total factor productivity. thee mechanism for the digital economy to cultivate new drivers for the high-quality development of China’s economy is through four dimensions, namely allocation optimization, economies of scale, industrial integration, and innovation-driven growth. In the context of the digital economy, accelerating the cultivation of new drivers calls for the following efforts: speeding up digital innovation and promoting the driving force change, efficiency change, and quality change; accelerating the process of digital industrialization and pushing advanced industrial basic capabilities; using industrial digital transformation to promote the modernization of the industrial chain; and advancing the high-quality development of the manufacturing industry, and promoting the deep integration of the digital economy and the real economy.

Sex-biased dispersal is common in group-living animals. Due to differences in local demographic and environmental factors, sex-biased dispersal presents many irregular patterns. In this study, a habituated, individually identified Yunnan snub-nosed monkey Rhinopithecus bieti group was observed over 9 years; 192 dispersal events, including 97 male dispersal events (25 natal dispersal and 72 secondary dispersal) and 95 female dispersal events (34 natal dispersal and 61 secondary dispersal) were observed. Males and females showed different dispersal paths, dispersal ages, and dispersal patterns. Females had 2 dispersal paths, whereas males had 4 paths. In terms of age of dispersal, the male age of natal dispersal was younger than for females. Males prefer single dispersal, whereas females prefer parallel dispersal. Our study indicates that the dispersal pattern of R. bieti should be classified as a bisexual dispersal pattern. The differences in dispersal path, average age at dispersal, and dispersal path pattern indicate that Yunnan snub-nosed monkeys may still retain a loose matrilineal social system.
