Accurately calculating detachment capacity is the most fundamental issue when establishing a soil erosion process model.Colluvial deposits of Benggang are typical soil-gravel mixtures,whereas the understanding of the soil detachment of colluvial deposits is limited.This work investigated the effects of the gravel contents on the soil detachment capacity of colluvial deposits and its hydrodynamic mechanism.The colluvial sample was collected in Anxi County,Fujian Province,Southeast China,and a small-sample scouring test was used.The slope steepness ranged from 18%to 84%,unit discharge ranged from 0.56×10^(-3)to 2.22×10^(-3)m^(2)s^(-1),and gravel content ranged from 0%to 70%.The results indicated that the gravel content is the primary factor that influences the detachment capacity,followed by the discharge and then the slope.The detachment capacity trend with the gravel content varied over different slopes and discharges.Stream power represents the best hydrodynamic parameter for modelling the detachment capacity of colluvial deposits and can be used to establish a fitting equation for the colluvium together with the mean weight diameter(MWD)(Nash-Sutcliffe efficiency(NSE)=0.96).As the gravel content increased,the soil erodibility parameters increased several folds,in some cases more than 10 folds,mainly because the soil shear strength decreased gradually.Meanwhile,as the gravel content increased,the gravel specific surface area increased,the obstruction of gravel to runoff increased,and the energy needed for runoff to overcome gravel obstruction increased,leading to 2-3 folds higher critical shear stress of runoff for soilgravel mixtures compared with pure soil.In summary,gravel can influence the detachment capacity by changing the soil properties,and the gravel content also affects the relationship between soil detachment capacity and the hydrodynamic parameters.These findings deepen the understanding of the influence of gravel on soil erosion and provide a basis for establishing a soil erosion process model in co

High-throughput sequencing technology is increasingly used in the study of nematode biodiversity.However,the annotation difference of commonly used primers and reference databases on nematode community is still unclear.We compared two pairs of primers(3NDf/C_1132rmod,NF1F/18Sr2bR)and three databases(NT_V20200604,SILVA138/18s Eukaryota and PR2_v4.5 databases)on the determination of nematode community from four different vegetation types in Changbai Mountain,including mixed broadleaf-conifer forest,dark coniferous forest,betula ermanii Cham and alpine tundra.Our results showed that the selection of different primers and databases influenced the annotation of nematode taxa,but the diversity of nematode community showed consistent pattern among different vegetation types.Our findings emphasize that it is necessary to select appropriate primer and database according to the target taxonomic level.The difference in primers will affect the result of nematode taxa at different classification levels,so sequencing analysis cannot be used for comparison with studies using different primers.In terms of annotation effect in this study,3NDf/C_1132rmod primers with NT_v20200604 database could provide more information than other combinations at the genus or species levels.

基于科学的企业是由科学家主导或参与创建,从事基础科学研究,通过基础科学成果的应用开发和商业转化获取经济利益,并在此过程中做出补充性科学研究的企业。针对基于科学的企业外部治理的研究呈现碎片化特征,有必要对现有研究进行系统性梳理和回顾。通过对相关文献检索和分析发现,由于基于科学的企业其特殊性,其外部治理框架相较于传统企业呈现出独特的外部治理视角:主要围绕传统的外部治理元素(政府规制、资本市场)和独特的外部治理元素(科技教育界行规)展开,因此本文着重深入关注这三类治理元素及其治理机制,以政府规制、资本市场、科技教育界行规为逻辑框架,对基于科学的企业外部治理机制涉及的元素、过程、治理效果及理论机制进行分析,全面回顾和总结了基于科学的企业外部治理研究现状和相关主题内容,归纳整合了基于科学的企业外部治理机制的全过程模型,并指出了未来的研究方向。本文丰富和拓展了基于科学的企业外部治理研究框架,为启发中国情境下基于科学的企业的外部治理理论与实践提供借鉴。

The occupational identity of nonexecutive directors exerts a considerable influence on their way of designing and distributing executive pay as well as ordinary employee pay in the focal firm.Integrating the status characteristics theory into the corporate governance literature,I theorize that status contest effect comes into play in the process of setting executive pay in the focal firm,specifically when its nonexecutive directors serve as executives on stakeholders.More often than not,such executive identity triggers the status competition with focal firm executives,which motivates nonexecutive directors to reduce the focal firm executive pay so as to secure and aggrandize their own status within the focal firm.However,since ordinary employees pose no threat to nonexecutive directors in the focal firm,they tend to increase ordinary employee pay.Basing upon the empirical test which adopts the data of China’s Shanghai and Shenzhen A-share listed firms,I find that the greater the focal firm’s nonexecutive director ratio,the less will be the top executives’pay in the focal firm;the greater the focal firm’s nonexecutive director ratio,the greater will be ordinary employees’pay in the focal firm;the greater the focal firm’s nonexecutive director ratio,the smaller will be the pay gap between top executives and ordinary employees in the focal firm.In addition,I also find that ownership power and gender can moderate the relationship between nonexecutive director ratio and executive pay:top executive ownership can alleviate the negative relationship between focal firm’s nonexecutive directors and top executives’pay;female nonexecutive directors are more likely to increase focal firm’s ordinary employee pay than their male counterparts.

The epithelial-mesenchymal transition(EMT)is a highly complex phenotypic conversion during embryogenesis,and is important for metastasis,which contributes to tumor deterioration and poor prognoses of cancer patients.Lung carcinoma has a high tendency to develop the EMT.Circular RNAs(circ RNAs)are involved in EMT-related cell invasion and metastasis in various types of cancers.Moreover,circ RNAs have been found to be a link to EMT-related transcription factors and EMT-associated signaling pathways.This review mainly focuses on the influence of EMT-related circ RNAs on lung carcinomas.More specifically,the roles of EMT-inducingand EMT-suppressive circ RNAs in lung carcinomas are discussed.With circ RNAs potentially becoming promising biomarkers and therapeutic targets for cancer managements,they will hopefully stimulate the interest of medical workers in the early diagnosis,personalized treatment,and positive prognoses in the era of precision oncology.

Rice blast,caused by the fungal pathogen Magnaporthe oryzae,is one of the most important diseases of rice.Utilization of blast-resistance genes is the most economical,effective,and environmentally friendly way to control the disease.However,genetic resources with broad-spectrum resistance(BSR)that is effective throughout the rice growth period are rare.In this work,using a genome-wide association study,we identify a new blast-resistance gene,Pijx,which encodes a typical CC-NBS-LRR protein.Pijx is derived from a wild rice species and confers BSR to M.oryzae at both the seedling and panicle stages.The functions of the resistant haplotypes of Pijx are confirmed by gene knockout and overexpression experiments.Mechanistically,the LRR domain in Pijx interacts with and promotes the degradation of the ATP synthase β subunit(ATPb)via the 26S proteasome pathway.ATPb acts as a negative regulator of Pijx-mediated panicle blast resistance,and interacts with OsRbohC to promote its degradation.Consistently,loss of ATPb function causes an increase in NAPDH content and ROS burst.Remarkably,when Pijx is introgressed into two japonica rice varieties,the introgression lines show BSR and increased yields that are approximately 51.59%and 79.31%higher compared with those of their parents in a natural blast disease nursery.In addition,we generate PPL^(Pijx Pigm) and PPL^(Pijx Piz-t) pyramided lines and these lines also have higher BSR to panicle blast compared with Pigm-or Piz-t-containing rice plants.Collectively,this study demonstrates that Pijx not only confers BSR to M.oryzae but also maintains high and stable rice yield,providing new genetic resources and molecular targets for breeding rice varieties with broad-spectrum blast resistance.

Objective:The purpose of this study was to explore the function and gene expression regulation of the newly identified lnc RNA DPP10-AS1 in lung cancer,and its potential value as a prognostic biomarker.Methods:q RT-PCR and Western blot were conducted to detect the expression of DDP10-AS1 and DPP10 in lung cancer cell lines and tissues.The effects of DDP10-AS1 on DPP10 expression,cell growth,invasion,apoptosis,and in vivo tumor growth were investigated in lung cancer cells by Western blot,rescue experiments,colony formation,flow cytometry,and xenograft animal experiments.Results:The novel antisense lnc RNA DPP10-AS1 was found to be highly expressed in cancer tissues(P<0.0001),and its upregulation predicted poor prognosis in patients with lung cancer(P=0.0025).Notably,DPP10-AS1 promoted lung cancer cell growth,colony formation,and cell cycle progression,and repressed apoptosis in lung cancer cells by upregulating DPP10 expression.Additionally,DPP10-AS1 facilitated lung tumor growth via upregulation of DPP10 protein in a xenograft mouse model.Importantly,DPP10-AS1 positively regulated DPP10 gene expression,and both were coordinately upregulated in lung cancer tissues.Mechanically,DPP10-AS1 was found to associate with DPP10 m RNA but did not enhance DPP10 m RNA stability.Hypomethylation of DPP10-AS1 and DPP10 contributed to their coordinate upregulation in lung cancer.Conclusions:These findings indicated that the upregulation of the antisense lnc RNA DPP10-AS1 promotes lung cancer malignant processes and facilitates tumorigenesis by epigenetically regulating its cognate sense gene DPP10.DPP10-AS1 may serve as a candidate prognostic biomarker and a potential therapeutic target in lung cancer.
