چکیده

Analysis of variance (ANOVA) refers to statistical models and associated procedures, in which the observed variance is partitioned into components due to different explanatory variables. It provides a statistical test concerning if the means of these several groups are all equal. In its simplest form, ANOVA is equivalent to Student's t-test when only two groups are invloved. The analysis of variance were first developed by R. A. Fisher in the 1920s and 1930s1. Thus, it is also known as Fisher's analysis of variance, or Fisher's ANOVA.

A novel catalyst of WO2 nanorod for the counter electrode of dye-sensitized solar cells.

Tungsten dioxide (WO(2)) nanorods were synthesized, which showed excellent catalytic activity for the reduction of triiodide to iodide. The dye-sensitized solar cell (DSC) using WO(2) as a counter electrode (CE) reached a high energy conversion efficiency of 7.25%, which can match the performance of the DSC based on a Pt CE.

Novel counter electrode catalysts of niobium oxides supersede Pt for dye-sensitized solar cells.

Synthesized niobium oxides (Nb(2)O(5) and NbO(2)) were applied for the first time as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). The DSC using NbO(2) CE showed a higher power conversion efficiency of 7.88%, compared with that of the DSC using Pt CE (7.65%).

Hsa-miR-875-5p exerts tumor suppressor function through down-regulation of EGFR in colorectal carcinoma (CRC)

Hsa-miRNA-875-5p (miR-875-5p) has recently been discovered to have anticancer efficacy in different organs. However, the role of miR-875-5p on colorectal carcinoma (CRC) is still ambiguous. In this study, we investigated the role of miR-875-5p on the development of CRC. The results indicated that miR-875-5p was significantly down-regulated in primary tumor tissues and very low levels were found...
