Elucidating cellular architecture and cell-type evolution across species is central to understanding immune system function susceptibility disease. Adaptive immunity a shared trait of the common ancestor cartilaginous bony fishes. However, evolutionary features lymphocytes in these two jawed vertebrates remain unclear. Here, we present single-cell RNA sequencing atlas cells from (white-spotted bamboo shark) (zebrafish Chinese tongue sole) Cross-species comparisons show that same cell types...

Lower to Middle Cretaceous red sandstones were sampled at four localities in the Lanpin-Simao fold belt of Shan-Thai Block describe its regional deformational features. Most samples revealed a characteristic remanent magnetization with unblocking temperatures around 680 °C. Primary natures are ascertained through positive test. A tilt-corrected formation-mean direction for Jingdong (24.5°N, 100.8°E) locality, which is located distance 25 km from Ailaoshan–Red River Fault, northerly...

As the only surface water source for Beijing, Miyun Reservoir and its catchment (MRC) are a focus concern about degradation of ecosystem services (ES) unless appropriate payments (PES) in place. This study used contingent valuation method (CVM) to estimate costs two new PES programs, agriculture forestry, further calculate economic value ES MRC from perspective local rural households’ willingness accept (WTA). The results Logit model including WTA variables household village indicate that...

Cretaceous red sandstones of the Feitianshan Formation and Xiaoba were sampled at 33 sites from Dadeli Mishi synclines Xichang (27.9°N, 102.3°E). The study area is a part Chuan Dian fragment bounded by Xianshuihe–Xiaojiang Red River fault systems, which in turn constitute southwestern Yangtze Block. Almost all samples give characteristic palaeomagnetic direction with unblocking temperatures up to 680°C. primary nature magnetization ascertained positive fold test 99 per cent confidence level...

Previous palaeomagnetic studies have demonstrated that a large part of the South China Block (SCB) has behaved as stable body since Cretaceous. We undertook investigation Lower Cretaceous red sandstones at 24 sites within Ganzhou and Xingguo basins in southern Jiangxi Province China. The aim this study was to further constrain extent SCB, which been isolated characteristic directions higher temperature components (HTCs) with an unblocking from 650 700 °C, by progressive thermal...

At present, China's urbanization process is accelerating, urban pressure gradually increasing, and problems are becoming more serious. The GIS technology based on the powerful analysis function of computer provides a new solution response strategy for construction smart cities. This paper focuses application in city construction, mainly involving platform, resource integration, transportation, planning emergency management. And role 3D visualization, spatial real-time data sharing this...

Wetlands play an important role in the terrestrial ecosystem. However, agricultural activities have resulted a significant decrease natural wetlands around world. In Tumen River Basin (TRB), border area between China, Democratic People’s Republic of Korea (DPRK), and Russia, been reclaimed converted into farmland, primarily due to migration practices Korean-Chinese. To understand spatial temporal patterns this conversion from Landsat remote sensing images four time periods were analyzed....

Abstract Vegetation plays a crucial role in river hydrodynamic processes, and the accurate prediction of canopy drag force is essential for effective management ecosystem protection. The interactions within vegetation canopies must be quantified to understand their impact on force. Through series flume experiments, we conducted an investigation into interaction mechanism rigid emergent aquatic vegetation, particularly focusing blockage sheltering effects. Our experimental design includes...
