DNA G‐quadruplexes (G4s) have been identified as critical elements in modulating genomic functions and many other biological processes. Their functions are highly dependent on the primary nucleotides and secondary folding structures. Therefore, to understand their functions, methods to identify and differentiate structures of G4 with speed and accuracy are required but limited. In this report, we...

The hybrid high voltage direct current (Hybrid HVDC) system based on line commutated converter (LCC) and modular multilevel converter (MMC) is a feasible solution for long distance bulk power transmission. In order to handle the dc-side short-circuit fault, two kinds of methods can be adopted. The first one is to replace half-bridge sub-modules (HBSMs) with full-bridge SMs or clamp-double SMs which...
A novel soft-switching single-phase three-arm dynamic voltage restorer (DVR) is analyzed and designed. The proposed soft-switching three-arm DVR which can solve the abnormal voltage problems such as voltage swell, voltage sag, over-voltage, under-voltage and harmonics. The proposed scheme is composed of a three-arm topology which operates as a rectifier and an inverter. Rather than the conventional...
This paper presents a soft-switching single-phase three-arm dynamic voltage restorer which aimed at solving voltage disturbances such as voltage swell, voltage sag, over-voltage and under-voltage. The proposed scheme is composed of a three-arm topology which operates as a rectifier and an inverter. Rather than the conventional four-arm topology, the proposed three-arm topology not only reduces the...
A memory system that meets the bandwidth, power efficiency, and capacity needs of future computing systems is presented in this paper. A 6.4 Gbps single-ended DDR memory interface for the controller and the DRAM was designed in a 28-nm CMOS process for a main memory system with dual-rank DIMMs. The architecture features a novel clocking scheme, per-pin timing adjustment, dynamic point-to-point signaling...
Based on the idea of generating NC tool-path from the point cloud directly, the topology reconstruction methods of scattered point cloud are emphatically studied in this paper. The scattered point cloud is divided at equal intervals and stored in link list structure in the process of topology reconstruction. In each data region, the points are reduced and projected to a middle slice plane, obtaining...
This paper study how to establish topology graphs from a topology embryonic graph with the help of computer in type synthesis of parallel mechanisms. The character of TGs are depicted by character arrays. Define what is isomorphic CAs in virtue of the concept of character string. Then put forward the new approach to identify isomorphism of CAs by using identification matrix. The program finding all...
