MYBs are a vital family of transcription factorsthat play critical roles in plant development and stressresponse. However, knowledge concerning the functions ofMYBs in the non-model plants is still limited. In this study,we isolated a R1-type MYB gene from maize (Zea mays L.),designated as ZmMYB48. Quantitative RT-PCR analysisdemonstrated that ZmMYB48 expression was induced bydrought and ABA treatments. Subcellular localization analysisrevealed that ZmMYB48 protein was targeted to the nucleusin tobacco leaf epidermal cells. Transactivation assay in yeastdemonstrated that ZmMYB48 had transcriptional activationability. Heterologous overexpression of ZmMYB48 inArabidopsis remarkably improved plant tolerance to droughtstress, as determined through physiological analyses ofsurvival rate, relative water content, malonaldehyde content,relative electrolyte leakage and proline content. Moreover,overexpression of ZmMYB48 enhanced the expression ofstress/ABA-responsive genes such as P5CS1, RD22, RD29Band ABI1. In addition, ZmMYB48-overexpressing plantsaccumulated higher content of ABA than WT plants underdrought stress. These results demonstrate that ZmMYB48might act as a positive regulator that participates in thedrought stress response through ABA signalling.

Polymer dielectrics are insulators or energy storage materials widely used in electrical and electronic devices. Polymer dielectrics are needed with outstanding dielectric characteristics than current technologies. In this study, the self-assembly of boron nitride nanosheets (BNNSs) was applied to form an inorganic–organic nanocoating on various common polymer dielectrics. It is inexpensive and easy to fabricate this thin coating on a large scale. The coating has a wide bandgap and thus can significantly improve the breakdown strength of polymer dielectrics. The charge characteristics and trapping parameters of nano-domains on the surfaces of polymer dielectrics were measured, and the coating had shallow trap levels. This facilitated the dissipation of surface charges and thus greatly increased the flashover voltage. The coating also effectively improved the temperature stability and dielectric constant of the polymer dielectric. This nanocoating shows potential as a method to effectively improve the dielectric characteristics of polymer dielectrics and outperform existing composite polymer dielectrics, which are crucial for large-scale applications in energy storage and power and electronic devices.

Wang, Wen-Long,Liu, Ming-Hui,Zhao, Xi-Cai 대한전기학회 2014 The Journal of International Council on Electrical Vol.4 No.2
The network structure of the smart substation in common use was introduced, and the technical problem of the shared-network of sampled measured value (SMV) and generic object oriented substation event (GOOSE) was analyzed, such as the processing ability of network device and the intelligent device, the data real-time property and the network reliability, the effects to the substation in the condition of network fault, and so on. On this basis, the feasibility of the shared-network of SMV and GOOSE was discussed, the implement scheme were presented, and eventually came to the solution of the shared-network of SMV and GOOSE, which based on the applications of the message priority control, restricting the switch number, virtual local area network (VLAN) and GARP multicast registration protocol (GMRP) classification flow control, etc. In the test-bed, the cases of shared-network and separate-network of SMV and GOOSE were compared and analyzed, and the result was valuable for reference.

Novel polyvinylidenefluoride (PVDF) hybrid ultrafiltration membranes with antifouling and antibacterialproperties are prepared by embedding N-halamine functionalized silica nanospheres (HFSNs). With theaddition of HFSNs, the antifouling properties of PVDF membranes are significantly improved. The resultsreveal that the highest pure water permeationflux of 559.8 L m 2 bar 1 h 1 is attained when the 0.6 wt%HFSNs is added in the casting solution. The membrane of M-3 with 0.9 wt% HFSNs addition shows thehighest sterilization ratios of 97.1% and 97.0% against (escherichia coli) E. coli and (staphylococcus aureus)S. aureus respectively. After 6 times of inhibition-activation cycles, the membrane still remains 72.3%against E.coli.

왕제(Wang, Jie),종명희(Zhong, Ming-Xi),김동식(Kim, Dongsik) 한국주거학회 2021 한국주거학회 학술대회논문집 Vol.33 No.2
As we enter an aging society, the good and bad of elderly care facilities are emerging as a social concern. Accordingly, the selection criteria for elderly care facilities are expanding from the inside to the outside. Currently, there are not many studies on the space outside the building in nursing homes for the elderly. Therefore, there is a desperate need for overall planning and research on the environment of the space outside the building of the elderly care facility. This paper examines the external spaces of two elderly care facilities, focusing on four specific areas of the external space: entry space, exercise space, rest space, and empty space. In order to improve the efficiency of the outer space of elderly care facilities, research is conducted and plans are presented in accordance with seven criteria of NEAP (Nursing Home Environmental Assessment Process). The purpose of this paper is to present a direction for reference during the research and practice process that enables the elderly to provide a comfortable, safe and efficient residential environment through research.

Background Paclitaxel is a chemotherapeutic drug for cancer, which is isolated from the Pacifc yew tree. However, and the molecular mechanism and the antitumor efects of paclitaxel on osteosarcoma cell remain to be explored. Objective The aim of our study was to explore the possible molecular mechanisms of apoptosis in osteosarcoma induced by paclitaxel. Results Paclitaxel can obviously decrease the proliferation of HOS-732 cells in a dose-dependent manner. Paclitaxel could induce the cell cycle arrest at the G2/M-phase and decreases the CDK5 and CCNE1 expression in HOS-732 cells. Paclitaxel promotes cell apoptosis in HOS-732 cells, which may be contacted to the decreasing of Bcl-2 protein expression. Further, the production of ROS in HOS-732 cells was remarkably increased with the increasing concentration of paclitaxel. Moreover, paclitaxel induces the ER-stress related gene and protein expression (GRP79, DDIT3 mRNA and GRP78, XBP-1 s, IRE1α protein expression) in osteosarcoma cells. Conclusion Paclitaxel can inhibit the proliferation of HOS-732 cells and increase ROS and ER-stress response to promote cell apoptosis, suggesting that paclitaxel may represent a new therapeutic option for the treatment and prevention osteosarcoma.

Ran Wang,Weiguo Xia,Xi-Ming Sun 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10
This paper investigates the circular formation control problem of car-like robots with limited sensing range. A path following strategy is proposed to drive the robots to the target circle by controlling the steering velocity. The forward speed controller is designed using the relative position measurements of neighboring robots to guarantee collision avoidance, and finally makes the robots realize a desired spacing configuration. Simulations on enclosing a static target and a moving target with circular formation are both given to validate our results.
Phase Switching Mechanism for WiFi-based Long Distance Networks in Industrial Real-Time Applications
( Jintao Wang ),( Xi Jin ),( Peng Zeng ),( Zhaowei Wang ),( Ming Wan ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.1
High-quality industrial control is critical to ensuring production quality, reducing production costs, improving management levels and stabilizing equipment and long-term operations. WiFi-based Long Distance (WiLD) networks have been used as remote industrial control networks. Real-time performance is essential to industrial control. However, the original mechanism of WiLD networks does not minimize end-to-end delay and restricts improvement of real-time performance. In this paper, we propose two algorithms to obtain the transmitting/receiving phase cycle length for each node such that real time constraints can be satisfied and phase switching overhead can be minimized. The first algorithm is based on the branch and bound method, which identifies an optimal solution. The second is a fast heuristic algorithm. The experimental results show that the execution time of the algorithm based on branch and bound is less than that of the heuristic algorithm when the network is complex and that the performance of the heuristic algorithm is close to the optimal solution.

Background: Radiotherapy is an important treatment of choice for breast cancer patients after breast-conserving surgery, and we compare the feasibility of using dual arc volumetric modulated arc therapy (VMAT2), single arc volumetric modulated arc therapy (VMAT1) and Multi-beam Intensity Modulated Radiotherapy (M-IMRT) on patients after breast-conserving surgery. Materials and Methods: Thirty patients with breast cancer (half right-sided and half left-sided) treated by conservative lumpectomy and requiring whole breast radiotherapy with tumor bed boost were planned with three different radiotherapy techniques: 1) VMAT1; 2) VMAT2; 3) M-IMRT. The distributions for the planning target volume (PTV) and organs at risk (OARs) were compared. Dosimetries for all the techniques were compared. Results: All three techniques satisfied the dose constraint well. VMAT2 showed no obvious difference in the homogeneity index (HI) and conformity index (CI) of the PTV with respect to M-IMRT and VMAT1. VMAT2 clearly improved the treatment efficiency and can also decrease the mean dose and V5Gy of the contralateral lung. The mean dose and maximum dose of the spinal cord and contralateral breast were lower for VMAT2 than the other two techniques. The very low dose distribution (V1Gy) of the contralateral breast also showed great reduction in VMAT2 compared with the other two techniques. For the ipsilateral lung of right-sided breast cancer, the mean dose was decreased significantly in VMAT2 compared with VMAT1 and M-IMRT. The V20Gy and V30Gy of the ipsilateral lung of the left-sided breast cancer for VMAT2 showed obvious reduction compared with the other two techniques. The heart statistics of VMAT2 also decreased considerably compared to VMAT1 and M-IMRT. Conclusions: Compared to the other two techniques, the dual arc volumetric modulated arc therapy technique reduced radiation dose exposure to the organs at risk and maintained a reasonable target dose distribution.
