7Community phylogenetic structure of grasslands and its relationship with environmental factors on the Mongolian Plateau显示文摘The community assembly rules and species coexistence have always been interested by ecologists. The community phylogenetic structure is the consequence of the interaction process between the organisms and the abiotic environment and has been used to explain the relative impact of abiotic and biotic factors on species co-existence. In recent years, grassland degradation and biodiversity loss have become increasingly severe on the Mongolian Plateau, while the drivers for these changes are not clearly explored, especially whether climate change is a main factor is debated in academia. In this study, we examined the phylogenetic structure of grassland communities along five transects of climate aridity on the Mongolian Plateau, and analyzed their relations with environmental factors, with the aims to understand the formation mechanism of the grassland communities and the role of climatic factors. We surveyed grassland communities at 81 sites along the five transects, and calculated their net relatedness index(NRI) at two different quadrat scales(small scale of 1 m2 and large scale of 5 m2) to characterize the community phylogenetic structure and analyze its relationship with the key 11 environmental factors. We also calculated the generalized UniFrac distance(GUniFrac) among the grassland communities to quantify the influence of spatial distance and environmental distance on the phylogenetic β diversity. The results indicated that plant community survey using the large scale quadrat contained sufficient species to represent community compositions. The community phylogenetic structure of grasslands was significantly overdispersed at both the small and large scales, and the degree of overdispersion was greater at the large scale than at the small scale, suggesting that competitive exclusion instead of habitat filtering played a major role in determination of community composition. Altitude was the main factor affecting the community phylogenetic structure, whereas climatic factors, such as precipitation and temperature, had limited influence. The principal component analysis of the 11 environmental factors revealed that 94.04% of their variation was accounted by the first four principal components. Moreover only 14.29% and 23.26% of the variation in community phylogenetic structure were explained by the first four principal components at the small and large scales, respectively. Phylogenetic β diversity was slightly significantly correlated with both spatial distance and environmental distance, however, environmental distance had a less explanatory power than spatial distance, indicating a limited environmental effect on the community phylogenetic structure of grasslands on the Mongolian Plateau. In view of the limited effect of climatic factors on the community phylogenetic structure of grasslands, climate change may have a smaller impact on grassland degradation than previously thought.DONG Lei LIANG Cunzhu LI Frank Yonghong ZHAO Liqing MA Wenhong WANG Lixin WEN Lu ZHENG Ying LI Zijing ZHAO Chenguang Indree TUVSHINTOGTOKH 2019Journal of Arid Land2019,11,4:2
8Comparing the VGCG model as the unification of dark sectors with observations显示文摘Current observations indicate that 95% of the energy density in the universe is the unknown dark component.The dark component is considered composed of two fluids:dark matter and dark energy.Or it is a mixture of these two dark components,i.e.,one can consider it an exotic unknown dark fluid.With this consideration,the variable generalized Chaplygin gas(VGCG)model is studied with not dividing the unknown fluid into dark matter and dark energy parts in this paper.By using the Markov Chain Monte Carlo method,the VGCG model as the unification of dark sectors is constrained,and the constraint results on the VGCG model parameters are,n=0.00057+0.0001+0.0009-0.0006-0.0006,α=0.0015+0.0003+0.0017-0.0015-0.0015and B s=0.778+0.016+0.030-0.016-0.035,obtained by the cosmic microwave background data from the 7-year WMAP full data points,the baryon acoustic oscillation data from Sloan Digital Sky Survey(SDSS)and 2-degree Field Galaxy Redshift(2dFGRS)survey,and the Union2 type Ia supernova data with systematic errors.At last,according to the evolution of deceleration parameter it is shown that an expanded universe from deceleration to acceleration can be obtained in VGCG cosmology.LU JianBo CHEN LiDong XU LiXin LI TianQiang 2014Science China(Physics,Mechanics & Astronomy)2014,57,4:2
9Interleukin 1 beta-induced chloride currents are important in osteoarthritis onset:an in vitro study显示文摘Persistent hypotonic and inflammatory conditions in the joint cavity can lead to the loss of cartilage matrix and cell death,which are the important mechanisms of osteoarthritis(OA)onset.Previous studies have confirmed that the existence of a hypotonic environment is a red flag for inflammation,as hypotonic environment induces the opening of the chloride channel of the cell and promotes chloride ion efflux,which prompts the cell volume to increase.Chloride channels play an important role in the regulation of mineralization and chondrocyte death.Here,we reported that OA chondrocytes showed a significant increase of cell death rate and the imbalance of cartilage matrix catabolism.We found that the distribution of skeleton protein F-actin was disordered.In addition,the volume-sensitive chloride current of OA chondrocytes decreased significantly with the increase of the expression levels of inflammation-related proteins caspase-1,caspase-3,and NLRP3.Moreover,interleukin-1β(IL-1β)showed a potential to activate the chloride current of normal chondrocytes.These results indicate that IL-1β-induced chloride channel opening in chondrocytes may be closely related to the occurrence of OA.This chloride channel opening process may therefore be a potential target for the treatment of OA.Zhiqin Deng Zicong Lin Qing Zhong Minqiang Lu Huankun Fang Jianquan Liu Li Duan Lixin Chen Liwei Wang Daping Wang Wencui Li 2021Acta Biochimica et Biophysica Sinica2021,53,4:2

12Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications.Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han 2018Journal of Semiconductors2018,39,3:1
13Bullet-like vanadium-based MOFs as a highly active catalyst for promoting the hydrogen storage property in MgH_(2)显示文摘The practical application of magnesium hydride(MgH_(2))was seriously limited by its high desorption temperature and slow desorp-tion kinetics.In this study,a bullet-like catalyst based on vanadium related MOFs(MOFs-V)was successfully synthesized and doped with MgH_(2) by ball milling to improve its hydrogen storage performance.Microstructure analysis demonstrated that the as-synthesized MOFs was consisted of V_(2)O_(3) with a bullet-like structure.After adding 7wt%MOFs-V,the initial desorption temperature of MgH_(2) was reduced from 340.0 to 190.6℃.Besides,the MgH_(2)+7wt%MOFs-V composite released 6.4wt%H_(2) within 5 min at 300℃.Hydrogen uptake was started at 60℃under 3200 kPa hydrogen pressure for the 7wt%MOFs-V containing sample.The desorption and absorption apparent activity energies of the MgH_(2)+7wt%MOFs-V composite were calculated to be(98.4±2.9)and(30.3±2.1)kJ·mol^(-1),much lower than(157.5±3.3)and(78.2±3.4)kJ·mol^(−1) for the as-prepared MgH_(2).The MgH_(2)+7wt%MOFs-V composite exhibited superior cyclic property.During the 20 cycles isothermal dehydrogenation and hydrogenation experiments,the hydrogen storage capacity stayed almost unchanged.X-ray diffraction(XRD)and X-ray photoelectron spectrometer(XPS)measurements confirmed the presence of metallic vanadium in the MgH_(2)+7wt%MOFs-V composite,which served as catalytic unit to markedly improve the hydrogen storage properties of Mg/MgH_(2) system.Zhiyu Lu Jiahuan He Mengchen Song Yan Zhang Fuying Wu Jiaguang Zheng Liuting Zhang Lixin Chen 2023International Journal of Minerals,Metallurgy and Materials2023,30,1:1
