We have developed a FORTRAN programme for scanning DNA sequences for potential Z-DNA forming regions using the One-Sample Runs Test. The programme also detects other non-random arrangements of purines and pyrimidines on the same strand and will detect purine- or pyrimidine-rich strands and G:...
1 新型不对称三电平四桥臂逆变器 对文献[4]中不对称结构进行扩展,提出一种新型三相不对称三电平四桥臂Z源逆变器如图1所示。 在逆变器的直流输入端与逆变桥之间引入一个Z源网络,直流侧上下电容电压可通过逆变器的上下直通来进行控制。其中C1=C2,L1=L2,UL1=UL2=UL,UC1=UC2=UC。直流电源电压为Udc。CS1=CS1...
In addition to the physical and optical characteristics, the synergistic effect between g-C3N4 and M88A was examined through electrochemical analysis and zeta potential analysis, and the reaction mechanism was elucidated in detail.

In this study, different varieties of natural starch, modified starch, and synthetic size materials are evaluated, and properties like retrogradation and desizability were studied to investigate their potential for modern weaving conditions. Comparison is made between various materials and it is observed...
Analysing 4641 data of potential accidents recorded in past two years, ICTCLAS(Chinese Lexical Analysis System) and Pareto rule are used to extract high-frequency keywords, and association rule algorithm is used for mining relationships. The study suggests that some potential accidents and hazards ...
