Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease with increasing spread. Currently SFTS transmission has expanded beyond Asian countries, however, with definitive global extents and risk patterns remained obscure. Here we established an exhaustive database that included globally reported locations of human SFTS cases and the competent vector, Haemaphysalis longicornis (H. longicornis), as well as the explanatory environmental variables, based on which, the potential geographic range of H. longicornis and risk areas...

Data from: Functional and phylogenetic diversity explain different components of diversity effects on biomass production

Shurong Zhou, Mengjiao Huang, Xiang Liu & Marc W. Cadotte
The Anthropocene is defined by human-driven environmental change, with one consequence being the modern dramatic decline in biodiversity globally. This is especially worrisome given the long-acknowledged causal linkage between biodiversity and ecosystem functioning and the delivery of ecosystem services. However, the exact mechanisms driving biodiversity- ecosystem function (BEF) relationships remain unclear, specifically the linkages between species differences, measured by trait and phylogenetic distances, and how interactions, such as competitive inequality and stable coexistence via niche...

Proscillaridin A slows the prostate cancer progression through triggering the activation of endoplasmic reticulum stress

Fan Wang, Lin Liu, Yu Tong, Linfeng Li, Yanfeng Liu & Wei-Qiang Gao
Prostate cancer (PCa) is the second commonly diagnosed malignancy in men over the world. Although androgen deprivation therapy for advanced PCa patients has significantly improved their survival, the majority of these patients eventually develop castration-resistant prostate cancer (CRPC). Proscillaridin A (Pro A), a cardiac glycoside that is clinically used to treat various heart failure diseases, has been reported to have anticancer activity in several cancers. However, whether Pro A exerts an inhibitory effect on PCa...

Enterovirus 71 (EV71) is a major pathogen that causes hand, foot and mouth disease (HFMD), which is a life threatening disease in certain children. The pathogenesis of EV71-caused HFMD is poorly defined due to the lack of simple and robust animal models with severe phenotypes that recapitulate symptoms observed in humans. Here, we generated the infectious clone of a clinical isolate from a severe HFMD patient. Virus rescued from the cDNA clone was infectious in...

Composite quasi-likelihood for single-index models with massive datasets

Rong Jiang, Meng-Fan Guo & Xin Liu
The single-index models (SIMs) provide an efficient way of coping with high-dimensional nonparametric estimation problems and avoid the “curse of dimensionality.” Many existing estimation procedures for SIMs were built on least square loss, which is popular for its mathematical beauty but is non-robust to non-normal errors and outliers. This article addressed the question of both robustness and efficiency of estimation methods based on a new data-driven weighted linear combination of convex loss functions instead of...
