The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is a major maize pest worldwide and has caused huge economic loss. To explore the control tactics of S. frugiperda in mountain maize planting fields, studies were performed in China from 2020 to 2021 for screening the S. frugiperda-resistant maize variety, seed coating agents, chemical insecticides, and biological agents. The results showed that 75 g/hm 2 Emamectin benzoate had better controlling efficacy (with a control efficacy of 91.05% at 1d) than other chemicals, so it was recommended in the high incidence period of pests. Compared with other seed coating treatments, 50% Lumi ngwei TM625FS (with a control efficacy of 76.19% at 10d) was the best seed coating against S. frugiperda. The biological control “Telenomus remus + Picromerus lewisi” and “T. remus + Eocanthecona furcellata” had good control efficacy on S. frugiperda with 76.01%, 64.10% at 20d, respectively. Additionally, there were lower numbers of S. frugiperda in maize variety GuiDan6, BaoYu9, and YanBaiYu8. In summary, this research rec ommended four effective pest management strategies (GuiDan6-resistant maize variety, 50% Lumingwei TM625FS-seed coating agents, 5% emamectin benzoate-chemical pesticide, and “T. remus + P. lewisi”-biological control) in mountain maize planting fields. The study provided effective control strategies for
Metastasis-associated Factors Facilitating the Progression of Colorectal Cancer

Tumor metastasis remains the principal cause of treatment failure and poor prognosis in patients with colorectal cancer. It is a multistage process which includes proteolysis, motility and migration of cells, proliferation in a new site, and neoangiogenesis. A crucial step in the process of intra- and extra-vasation is the activation of proteolytic enzymes capable of degrading the extracellular matrix (ECM). In this stage, urokinase plasminogen activator receptor (uPAR) and matrix metalloproteinases (MMPs) are necessary. Micrometastases need the presence of growth factor and vascular growth factor so that they can form macrometastasis. In addition, cell adhesion molecules (CAMs) and guanine nucleotide exchange factors (GEFs) play important roles in the progression of colorectal cancer and metastatic migration. Further elucidation of the mechanisms of how these molecules contribute will aid in the identification of diagnostic and prognostic markers as well as therapeutic targets for patients with colorectal metastasis.

High performance robust force control of hydraulic load simulator with constant but unknown hydraulic parameters is considered. Incontrast to the linear control based on hydraulic linearization equations, hydraulic inherent nonlinear properties and uncertainties makethe conventional feedback proportional-integral-derivative (PID) control not yield to high performance requirements. Furthermore, thehydraulic system may be subjected to non-smooth and discontinuous nonlinearities due to the directional change of valve opening. In thispaper, based on a nonlinear system model of hydraulic load simulator, a discontinuous projection-based nonlinear adaptive robust backsteppingcontroller is developed with servo valve dynamics. The proposed controller constructs a novel stable adaptive controller andadaptation laws with additional pressure dynamic related unknown parameters, which can compensate for the system nonlinearities anduncertain parameters, meanwhile a well-designed robust controller is also synthesized to dominate the model uncertainties coming fromboth parametric uncertainties and uncertain nonlinearities including unmodeled and ignored system dynamics. The controller theoreticallyguarantee a prescribed transient performance and final tracking accuracy in presence of both parametric uncertainties and uncertainnonlinearities; while achieving asymptotic output tracking in the absence of unstructured uncertainties. The implementation issues arealso discussed for controller simplification. Some comparative results are obtained to verify the high-performance nature of the proposedcontroller.

포스트 모던 사상이 중국에 들어오면서, 중국의 사회, 문화 문제를 해결하고자 하는 젊은 예술가들의 작품 경향은 이전 세대의 예술가들과는 극명한 대조를 이루고 있다. 본 논문은 차오페이(曹斐)의 미디어 아트 <RMB City, 2007>를 연구대상으로 하여 작품 속 미시적 서사(Micro Narrative)의 특징을 분석한다. 이를 통해 중국 현대 미디어 아트 작품은 미시적 서사 측면에서 시대와 사회의 급격한 변화를 반영하고 있음을 알 수 있다. As post-modern ideas enter China, the tendency of young artists to work to solve social and cultural problems in China is in stark contrast to that of previous generations. This paper analyzes the characteristics of micro narration in the work with Cao Fei's media art <RMB City, 2007>. This shows that contemporary Chinese media art works reflect the rapid changes in the times and society in terms of micro-description.

Cordycepin exerts neuroprotective effects against excitotoxic neuronal death. However, its direct electrophysiological evidence in Alzheimer's disease (AD) remains unclear. This study aimed to explore the electrophysiological mechanisms underlying the protective effect of cordycepin against the excitotoxic neuronal insult in AD using whole-cell patch clamp techniques. ${\beta}$-Amyloid ($A{\beta}$) and ibotenic acid (IBO)-induced injury model in cultured hippocampal neurons was used for the purpose. The results revealed that cordycepin significantly delayed $A{\beta}$ + IBO-induced excessive neuronal membrane depolarization. It increased the onset time/latency, extended the duration, and reduced the slope in both slow and rapid depolarization. Additionally, cordycepin reversed the neuronal hyperactivity in $A{\beta}$ + IBO-induced evoked action potential (AP) firing, including increase in repetitive firing frequency, shortening of evoked AP latency, decrease in the amplitude of fast afterhyperpolarization, and increase in membrane depolarization. Further, the suppressive effect of cordycepin against $A{\beta}$ + IBO-induced excessive neuronal membrane depolarization and neuronal hyperactivity was blocked by DPCPX (8-cyclopentyl-1,3-dipropylxanthine, an adenosine $A_1$ receptor-specific blocker). Collectively, these results revealed the suppressive effect of cordycepin against the $A{\beta}$ + IBO-induced excitotoxic neuronal insult by attenuating excessive neuronal activity and membrane depolarization, and the mechanism through the activation of $A_1R$ is strongly recommended, thus highlighting the therapeutic potential of cordycepin in AD.
Novel Five-Level Three-Phase Hybrid-Clamped Converter with Reduced Components
Bin Chen,Wenxi Yao,Zhengyu Lu 전력전자학회 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.6
This study proposes a novel five-level three-phase hybrid-clamped converter composed of only six switches and one flying capacitor (FC) per phase. The capacitor-voltage-drift phenomenon of the converter under the classical sinusoidal pulse width modulation (SPWM) strategy is comprehensively analyzed. The average current, which flows into the FC, is a function of power factor and modulation index and does not remain at zero. Thus, a specific modulation strategy based on space vector modulation (SVM) is developed to balance the voltage of DC-link and FCs by injecting a common-mode voltage. This strategy applies the five-segment method to synthesize the voltage vector, such that switching losses are reduced while optional vector sequences are increased. The best vector sequence is then selected on the basis of the minimized cost function to suppress the divergence of the capacitor voltage. This study further proposes a startup method that charges the DC-link and FCs without any additional circuits. Simulation and experimental results verify the validity of the proposed converter, modulation strategy, and precharge method.
