| 1 | Analysis of t-test misuses and SPSS operations in medical research papers显示文摘In medical research papers,the selection of appropriate statistical methods serves as one of the pivotal premises to ensure the quality of papers and credibility of their results[1–3].To correctly perform the statistical analysis of quantitative data,two key points should be considered.One is to identify the type of experimental design correctly,and the other is to check whether data meets the preconditions of parameter test[2–4].Otherwise,it may cause different misuse in some situations and may even draw different or opposite conclusions about the same data. | Guangping Liang Wenliang Fu Kaifa Wang | 2019 | Burns & Trauma2019，7，1： | 3 |
| 2 | Vibration analysis of piezoelectric sandwich nanobeam with flexoelectricity based on nonlocal strain gradient theory显示文摘A nonlocal strain gradient theory(NSGT) accounts for not only the nongradient nonlocal elastic stress but also the nonlocality of higher-order strain gradients,which makes it benefit from both hardening and softening effects in small-scale structures.In this study, based on the NSGT, an analytical model for the vibration behavior of a piezoelectric sandwich nanobeam is developed with consideration of flexoelectricity. The sandwich nanobeam consists of two piezoelectric sheets and a non-piezoelectric core. The governing equation of vibration of the sandwich beam is obtained by the Hamiltonian principle. The natural vibration frequency of the nanobeam is calculated for the simply supported(SS) boundary, the clamped-clamped(CC) boundary, the clamped-free(CF)boundary, and the clamped-simply supported(CS) boundary. The effects of geometric dimensions, length scale parameters, nonlocal parameters, piezoelectric constants, as well as the flexoelectric constants are discussed. The results demonstrate that both the flexoelectric and piezoelectric constants enhance the vibration frequency of the nanobeam.The nonlocal stress decreases the natural vibration frequency, while the strain gradient increases the natural vibration frequency. The natural vibration frequency based on the NSGT can be increased or decreased, depending on the value of the nonlocal parameter to length scale parameter ratio. | Shan ZENG Kaifa WANG Baolin WANG Jinwu WU | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，6： | 2 |
| 3 | Argonaute protein as a linker to command center of physiological processes显示文摘MicroRNAs (miRNAs) post-transcriptionally regulate gene expression by binding to target mRNAs with perfect or imperfect complementarity, recruiting an Argonaute (AGO) protein complex that usually results in degradation or translational repression of the target mRNA. AGO proteins function as the Slicer enzyme in miRNA and small interfering RNA (siRNA) pathways involved in human physiological and pathophysiological processes, such as antiviral responses and disease formation. Although the past decade has witnessed rapid advancement in studies of AGO protein functions, to further elucidate the molecular mechanism of AGO proteins in cellular function and biochemical process is really a challenging area for researchers. In order to understand the molecular causes underlying the pathological processes, we mainly focus on five fundamental problems of AGO proteins, including evolution, functional domain, subcellular location, post-translational modification and protein-protein interactions. Our discussion highlight their roles in early diagnosis, disease prevention, drug target identification, drug response, etc. | Kaifa Wei Lingjuan Wu Yanhui Chen Yina Lin Yanmei Wang Xiaoyao Liu Daoxin Xie | 2013 | Chinese Journal of Cancer Research2013，25，4： | 2 |
| 4 | Fracture mechanics analysis of delamination in a thermoelectric pn-junction sandwiched by an insulating layer显示文摘A fracture mechanics analysis is conducted for a delamination problem of a multilayered thermoelectric material(TEM) that consists of an n-type layer and a p-type layer sandwiched by an insulating layer. A time-varying energy release rate is presented when the n-type layer delaminates from the insulating layer. Effects of the temperature difference across the system and the applied electric current on the energy release rate are identified. The influence of the thickness ratio of the insulating layer to the thermoelectric(TE) layer is also examined. Based on the energy release rate criterion,the critical temperature difference for delamination propagation is obtained. Some useful conclusions are given. | Youjiang CUI Kaifa WANG Baoling WANG | 2018 | Applied Mathematics and Mechanics(English Edition)2018，39，10： | 1 |
