High‐entropy (Ti_0.2V_0.2Nb_0.2Mo_0.2W_0.2)Si₂ with excellent high‐temperature wear resistance

Jicheng Li, Shuna Chen, Hengzhong Fan, Qiangqiang Zhang, more

Journal of the American Ceramic Society > 107 > 4 > 2750 - 2764

The oxidation products (MoO₃ and V₂O₅) have low melting points and tend to sublimate at high temperatures despite that MoSi₂ and VSi₂ may possess good self‐lubricating properties. To cope with this challenge, a high‐entropy transition metal disilicide was designed in this work in which transition metal elements that could form high melting point oxides were deliberately added. The high‐entropy (Ti...

Acupuncture, from the ancient to the current

Jiajie Zhu, Jicheng Li, Liangjun Yang, Shan Liu

The Anatomical Record > 304 > 11 > 2365 - 2371

Acupuncture is characterized by the insertion of a fine metal needle through the skin of the human body at an acupuncture point (acupoint) in Traditional Chinese Medicine (TCM). It is an ancient form of therapy, and has a long history of prosperity and decline. Due to the persistent efforts of TCM practitioners, a number of well‐designed clinical trials regarding acupuncture have been published in...

Yang Li, Guangjian Li, Jicheng Li, Xuewei Cai, more

Genes, Brain and Behavior > 20 > 4 > n/a - n/a

Circadian rhythm dysfunction is primary symptom of depression and is closely related to depression onset. The role of the lateral habenula (LHb) of the thalamus in the pathogenesis of depression has been a research topic of great interest. The neuronal activity of this structure has circadian characteristics, which are related to the regulation of circadian rhythms. However, in depression model of...

Shuqi Zhang, Hongbo Zhang, Jicheng Li, Jiaojiao Li

Environmental Earth Sciences > 2019 > 78 > 15 > 1-15

A new hybrid model called the AGCT model has been proposed for identifying an abrupt and gradual change in a hydrological time series. This hybrid model combining the over-whitening procedure, Pettitt test, and Mann–Kendall test can measure abrupt and gradual changes in hydrological series with mixed-mode shift and weight the attributions of two types of changes to the shift. In addition, four types...

Role of autophagy in inhibiting the proliferation of A549 cells by type III interferon

Dongmei Gao, Xiaoqin Yu, Bo Zhang, Min Kong, more

Cell Biology International > 43 > 6 > 605 - 612

Interferons (IFNs) have anti‐viral and anti‐tumour effects. Type III interferon, as a member of the recently discovered interferon family, has been proved to inhibit tumour proliferation and promote the apoptosis of various tumour cells. However, whether type III IFN could inhibit the proliferation of lung cancer was not clear. In this study, we found that interferon λ (IFN λ) could inhibit the proliferation...

Journal of Inequalities and Applications > 2017 > 2017 > 1 > 1-14

Low-rank matrix recovery is an active topic drawing the attention of many researchers. It addresses the problem of approximating the observed data matrix by an unknown low-rank matrix. Suppose that A is a low-rank matrix approximation of D, where D and A are m × n $m \times n$ matrices. Based on a useful decomposition of D † − A † $D^{\dagger} - A^{\dagger}$ , for the unitarily invariant...

Transcriptome data analysis of grass carp (Ctenopharyngodon idella) infected by reovirus provides insights into two immune-related genes

Zao Dai, Jicheng Li, Chengyu Hu, Fang Wang, more

Fish & Shellfish Immunology > 2017 > 64 > C > 68-77

Grass carp (Ctenopharyngodon idella) was one of the economically important freshwater fish in China. However, hemorrhagic disease caused by grass carp reovirus (GCRV) results in a tremendous loss in the process of grass carp cultivation. Transcriptome analysis could provide a comprehensive understanding of the molecular mechanisms involved in specific biological processes and diseases for the resistance...
