Pingping Xiao, Jizhen Wang, Tingting Li, Apeng Yang, more

Molecular Carcinogenesis > 63 > 4 > 728 - 741

Multiple myeloma (MM) remains an incurable disease. Identification of meaningful co‐expressed gene clusters or representative biomarkers of MM may help to identify new pathological mechanisms and promote the development of new therapies. Here, we performed weighted sgene co‐expression network analysis and a series of bioinformatics analysis to identify single stranded DNA binding protein 1 (SSBP1)...

Comparison of the risk of postoperative wound infection in patients with rectal cancer by laparoscopic versus open Hartmann's surgery

Yan Jiang, Rushi Liu, Qian You, Xiaoxiao Fan, more

International Wound Journal > 21 > 2 > n/a - n/a

Traditional Hartmann surgery is used when the patient is in an acute case where it might not be safe to carry out a one‐stage intestinal anastomosis. Laparoscopy has been extensively applied in the treatment of large intestine, which can significantly improve both short‐ and long‐term outcomes. While randomized, controlled studies and reviews have shown that laparoscopy is superior to that of open‐access...

Dehong Zheng, Zhiyong Zeng, Bingbing Xue, Yaoyao Deng, more

Microbiological Research > 2018 > 215 > C > 22-28

Bacillus thuringiensis has been widely used as a bio-insecticide. However, novel biological activities other than insect toxicity of B. thuringiensis are still underestimated. In this study, a new lipopeptide biosynthesis gene cluster in B. thuringiensis BMB171 was discovered by genome mining and verified by reverse genetics. Thumolycin, the lipopeptide synthesized by this gene cluster, was then isolated...

An endogenous microRNA (miRNA1166.1) can regulate photobio-H₂ production in eukaryotic green alga Chlamydomonas reinhardtii

Yuting Wang, Xiaoshan Zhuang, Meirong Chen, Zhiyong Zeng, more

Biotechnology for Biofuels > 2018 > 11 > 1 > 1-8

Background Hydrogen photoproduction from green microalgae is regarded as a promising alternative solution for energy problems. However, the simultaneous oxygen evolution from microalgae can prevent continuous hydrogen production due to the hypersensitivity of hydrogenases to oxygen. Sulfur deprivation can extend the duration of algal hydrogen production, but it is uneconomical to alternately culture...

Biotechnology for Biofuels > 2017 > 10 > 1 > 1-9

Background Chlamydomonas reinhardtii is an ideal model organism not only for the study of basic metabolic processes in both plants and animals but also the production of biofuels including hydrogen. Transgenic analysis of C. reinhardtii is now well established and very convenient, but inducible exogenous gene expression systems remain under-studied. The most commonly used heat shock-inducible system...

Torque ripple elimination based on inverter voltage drop compensation for a three-phase four-switch inverter-fed PMSM drive under low speeds

Chong Zhu, Zhiyong Zeng, Rongxiang Zhao

IET Power Electronics > 2017 > 10 > 12 > 1430 - 1437

Torque ripples under low speeds are a prominent issue of three-phase, four-switch (TPFS) inverter-fed permanent magnet synchronous motor (PMSM) drives. Due to the asymmetrical circuit topologies, the inverter voltage drops caused by semiconductor power switches have a unique influence on the performances of TPFS inverter-fed PMSM drives, producing unbalanced motor currents and pulsating torques. In...

Performance assessment for generalized delay-timers in alarm configuration

Zhiyong Zeng, Wen Tan, Rong Zhou

Journal of Process Control > 2017 > 57 > C > 80-101

False and nuisance alarms are major problems in the process industry. Generalized delay-timer is an effective technique to improve the performance of an alarm system. However, due to the increasing intermediate states, computation of the performance indices, false alarm rate (FAR), missed alarm rate (MAR) and expected detection delay (EDD), is hard and unsolved for generalized delay timer. In this...

Comprehensive Analysis and Reduction of Torque Ripples in Three-Phase Four-Switch Inverter-Fed PMSM Drives Using Space Vector Pulse-Width Modulation

Chong Zhu, Zhiyong Zeng, Rongxiang Zhao

IEEE Transactions on Power Electronics > 2017 > 32 > 7 > 5411 - 5424

As a result of their reduced number of switches, three-phase four-switch (TPFS) inverters are generally applied as cost-reduction topologies for permanent magnet synchronous motor (PMSM) drives. However, the torque ripples of PMSM severely deteriorate the performance and reliability of the entire system. Hence, comprehensive considerations for torque ripple reduction, including high- and low-frequency...

Hybrid Space Vector Modulation Strategy for Torque Ripple Minimization in Three-Phase Four-Switch Inverter-Fed PMSM Drives

Zhiyong Zeng, Chong Zhu, Xiaoliang Jin, Wen Shi, more

IEEE Transactions on Industrial Electronics > 2017 > 64 > 3 > 2122 - 2134

Three-phase four-switch (TPFS) inverters are generally applied as cost-reduction topologies for permanent-magnet synchronous motor (PMSM) drives because of their reduced number of switching devices. However, undesirable torque ripples are produced by the inverter-fed PMSMs due to the application of nonsinusoidal voltages. Because the torque ripples are strongly influenced by the employed pulse width...

Journal of Autoimmunity > 2017 > 77 > C > 67-75

Previous studies have revealed a critical role of YY1, a “Yin Yang” transcription factor, in cancer development and progression. However, whether YY1 has any role in rheumatoid arthritis (RA) remains unknown. This study aims to explore the potential role of YY1 in RA pathogenesis. In this study, we found that YY1 was over-expressed in RA patients and CIA mice. Blocking of YY1 action with YY1 shRNA...

Chong Zhu, Zhiyong Zeng, Rongxiang Zhao

Electronics Letters > 2016 > 52 > 17 > 1442 - 1444

The DC-link voltage offset in three-phase four-switch (TPFS) inverter-fed permanent magnet synchronous motor (PMSM) drives deteriorates the linear modulation range severely, restricting the performance and adjustable speed range of the PMSM. An adaptive control method is proposed in this Letter to suppress the DC-link voltage offset in TPFS inverter-fed PMSM drives. By investigating the effects of...
