1Soil Erosion and Vegetation Succession in Alpine Kobresia Steppe Meadow Caused by Plateau Pika——A Case Study of Nagqu County, Tibet显示文摘This paper evaluated the impacts of mounds created by the plateau pika (Ochotona curzoniae) on the vege- tation composition, structure, and species diversity of an alpine Kobresia steppe meadow in Nagqu County, Tibet Autonomous Region, China. Based on mound height or the depth of erosion pit, we defined five stages of erosion and compared the floristic features of communities at these stages with those in undisturbed sites. In the study area, the mounds and pits covered up to 7% of the total area. Lancea tibetica, Lamiophlomis rotata, and Potentilla bifurca were the dominant species in erosion pits, and Kobresia pygmaea, the dominant species in undisturbed sites, became a com- panion species in eroded areas. In the process of erosion, the original vegetation was covered by soil ejected by the pika, then the mounds were gradually eroded by wind and rain, and finally erosion pits formed. The vegetation coverage in- creased with increasing erosion stages but remained significantly lower than that in undisturbed sites. Improved coverage eventually reduced soil erosion, and pit depth eventually stabilized at around 20cm. Aboveground biomass increased with increasing erosion stage, but the proportion of low-quality forage reached more than 94%. The richness index and Shannon-Wiener index increased significantly with increasing erosion stage, but the richness index in mound and pit areas was significantly lower than that in undisturbed sites.WEI Xinghu LI Sen Yang Ping Cheng Huaishun 2007Chinese Geographical Science2007,17,1:22

4A Continuous Leader-following Consensus Control Strategy for a Class of Uncertain Multi-agent Systems显示文摘In this paper, we study the robust leader-following consensus problem for a class of multi-agent systems with unknown nonlinear dynamics and unknown but bounded disturbances. The control input of the leader agent is nonzero and not available to any follower agent. We first consider a class of high order chain integrator-type multi-agent systems.By employing the robust integral of the sign of the error technique, a continuous distributed control law is constructed using local information obtained from neighboring agents. Using Lyapunov analysis theory, we show that under a connected undirected information communication topology, the proposed protocol achieves semiglobal leader-following consensus. We then extend the approach to a class of more general uncertain multiagent systems. A numerical example is given to verify our proposed protocol.Chuanrui Wang Xinghu Wang Haibo Ji 2014IEEE/CAA Journal of Automatica Sinica2014,1,2:6

6Changes in plant species composition and diversity of alpine Kobresia (Kobresia pygmaea) steppe meadow at different stages of desertification in the North Tibetan plateau显示文摘The impacts of desertification on the vegetation composition, structure, and species diversity of alpine Kobresia steppe meadow were evaluated in an area of severe desertification in Anduo County, Tibet Autonomous Region, northern China. We investigated and analyzed the floristic features of communities at four different stages of desertification (slight desertification [SLD], moderate desertification [MD], severe desertification [SD], and very severe desertification [VSD]). The composition and structure of the alpine Kobresia steppe meadow at the SLD site differed significantly from that at the MD, SD, and VSD sites. Species that were more drought resistant and inedible by livestock were the dominant species at the SD site. No plants were found in the shifting dunes of the VSD site. Species diversity also decreased with increasing desertification. The SLD site had the largest mean number of species and individuals and the largest richness index; the MD grassland had the largest Shannon-Wiener index and evenness index, but the smallest Simpson's index. The vegetation cover declined from 91.8% to 34.8% as desertification increased from SLD to SD, and reached 0% in VSD areas with shifting dunes.XingHu Wei 1*, Ping Yang 2, Sen Li 1, YuXiang Dong 3, ChunLai Zhang 41.

7The causes and processes responsible for rocky desertification in karst areas of southern China显示文摘The karst region of southern China is a fragile ecological zone with widespread rocky desertification. This paper describes the rocky desertification occurring in this region in terms of both natural and anthropogenic factors. During geological time periods, the region's changing environment governed the natural rocky desertification processes, whereas during historical and modern times, anthropogenic processes have been superimposed on these natural processes. Human activities have accelerated and exacerbated rocky desertification. The period from the beginning to the middle of the Qing dynasty was an important transitional period in which human activities began to exert a particularly strong influence on rocky desertification. Since then, the effect of anthropogenic factors has increasingly exceeded the effect of natural factors. The rocky desertification process in southern China's karst region combines surface ecological processes (including vegetation degradation and loss, soil erosion, surface water loss, and bedrock solution) with a reduction of the land's biological productivity, leading to degradation that produces rocky desert. Controlling rocky desertification requires comprehensive development of sustainable agriculture and economic development that provides employment alternatives to agriculture and thereby promotes the rehabilitation of rocky desertified land.Sen Li 1,2*, XingHu Wei 1, JinGuo Huang 1, XiZhi Wang 1, GuanYao Lu 1, HuiXia Li 11.

9Culturing adequate CAR-T cells from less peripheral blood to treat B-cell malignancies显示文摘Objective:Chimeric antigen receptor-modified T(CAR-T)cells have shown impressive results against relapsed/refractory B cell malignancies.However,the traditional manufacture of CAR-T cells requires leukapheresis to isolate large amounts of peripheral blood T cells,thus making some patients ineligible for the procedure.Methods:We developed a simple method for CAR-T cell preparation requiring small volumes of peripheral blood.First,CD3+T cells isolated from 50 mL peripheral blood from patients(B-cell malignancies)were stimulated with immobilized anti-CD3/RetroNectin in 6-well plates and then transduced with CAR-expressing lentiviral vector.After 4 d,the T cells were transferred to culture bags for large-scale CAR-T cell expansion.In vitro and animal experiments were performed to evaluate the activity of the manufactured CAR-T cells.Finally,29 patients with B-cell acute lymphoblastic leukemia(B-ALL)and 9 patients with B-cell lymphoma were treated with the CAR-T cells.Results:The CAR-T cells were expanded to 1–3×10^(8) cells in 8–10 d and successfully killed B cell-derived malignant tumor cells in vitro and in vivo.For patients with B-ALL,the complete remission rate was 93%1 month after CAR-T cell infusion;after 12 months,the overall survival(OS)and leukemia-free survival rates were 69%and 31%,respectively.For patients with lymphoma,the objective response rate(including complete and partial remission)was 78%2 months after CAR-T cell infusion,and after 12 months,the OS and progression-free survival rates were 71%and 43%,respectively.Cytokine-release syndrome(CRS)occurred in 65.51%and 55.56%of patients with B-ALL and B-cell lymphoma,respectively;severe CRS developed in 20.69%of patients with B-ALL and in no patients with lymphoma.Conclusions:Our novel method can generate sufficient numbers of CAR-T cells for clinical use from 50–100 mL peripheral blood,thus providing an alternative means of CAR-T cell generation for patients ineligible for leukapheresis.Lu Han Jian Zhou Linlin Li Keshu Zhou Lingdi Zhao Xinghu Zhu Qingsong Yin Yufu Li Hongqin You Jishuai Zhang Yongping Song Quanli Gao 2021Cancer Biology & Medicine2021,18,4:2

18A novel method for the synthesis of carbon dots assisted by free radicals显示文摘Carbon dots(CDs)have gradually become a widely favored type of fluorescent nanomaterials with unlimited and promising applications.This work reports a means of breaking the shackle of method to develop new red and white CDs by introducing free radicals.The resulting white emissive CDs in this strategy are employed to demonstrate electroluminescent white-light-emitting diodes(WLEDs)and achieve a record-high external quantum efficiency(0.95%)of one-step-produced white CDs(WCD)-LEDs,which dramatically simplifies the whole fabrication processes of WLEDs.With additional passivation treatment,the red CDs(RCD2)with excellent properties such as N and S co-doping,bright(quantum yield=49%)and stable photoluminescence(PL),large positive zeta potential(+20.5 mV),and two-photon fluorescence are obtained.Such RCD2 are used for rapid staining(5 min)of yeast cells.The two CDs synthesized via this method have outstanding performance in different aspects,which provides new promise of CDs for further functionalization and applications.Xinyue Zhou Kebing Yi Yeling Yang Guohua Xie Xinghu Ji Zhike He 2022Nano Research2022,15,10:1
