Bioassay-guided fractionation of CHCl3 extract from the fermentation broth of a sponge Mycale plumose-derived actinomycete Saccharopolyspora sp. nov., led to the isolation of two known prodigiosin analogs - metacycloprodigiosin (1) and undecylprodigiosin (2). These compounds exhibited significant cytotoxic activities against five cancer cell lines: P388, HL60, A-549, BEL- 7402, and SPCA4. This is the first report on the significant cytotoxicity of metacycloprodigiosin (1) against human cancer cell lines.

β-Aminobutyric acid (BABA) has consistently been reported to enhance plant immunity. However, the specific mechanisms and downstream components that mediate this resistance are not yet agreed upon. Nitric oxide (NO) is an important signal molecule involved in a diverse range of physiological processes, and whether NO is involved in BABA-induced resistance is interest- ing. In this study, treatment with BABA significantly increased NO accumulation and reduced the sensitivity to Botrytis cinerea in tomato plants. BABA treatment reduced physical signs of infection and increased both the transcription of key defense marker genes and the activity of defensive enzymes. Interestingly, compared to treatment with BABA alone, treatment with BABA plus cPTIO (NO specific scavenger) not only signifi- cantly reduced NO accumulation, but also increased disease incidence and lesion area. These results sug- gest that NO accumulation plays an important role in BABA-induced resistance against B. cinerea in tomato plants.

In a rapidly growing digital economic environment, NFT has emerged as a hot topic in the art field. However, in China, NFT art is developing slowly due to constraints related to China's political economy and socio-cultural situation. Due to strict management and control, the circulation of cryptocurrency is limited, and the level of public awareness and acceptance of NFT art and market maturity are still low. Despite these limitations, this paper predicts that Chinese art creators and market participants can build an online personal art IP model that suits the characteristics of the Chinese market and explores the current status and possibilities.

To investigate the effects of electrolyzed watertreatment on the qualities of rice noodles prepared withsemidry- milled rice flour, pasting properties and thermalproperties of rice flour, and the cooking and texturalproperties of rice noodles were determined. Higher peakviscosity and lower melting enthalpy were observed inelectrolyzed water (EW) treated rice flour. The hardness,gumminess and chewiness of rice noodle in slightly acidicelectrolyzed water treated rice noodles with availablechlorine concentration (ACC) 20.32 mg/L were increasedsignificantly (p\0.05). The cooking loss decreased significantlyin strong acidic electrolyzed water treated noodleswith ACC 10.09 mg/L treatment (p\0.05). Theresults indicated that EW could promote the gelatinizationof rice flour, and improve the textural qualities of ricenoodles. Therefore EW was appropriate to be used in ricenoodle production.
An Analytical Solution for Voltage Stability Studies Incorporating Wind Power
Lin, Yu-Zhang,Shi, Li-Bao,Yao, Liang-Zhong,Ni, Yi-Xin,Qin, Shi-Yao,Wang, Rui-Ming,Zhang, Jin-Ping The Korean Institute of Electrical Engineers 2015 Journal of Electrical Engineering & Technology Vol.10 No.3
Voltage stability is one of the most critical security issues which has not yet been well resolved to date. In this paper, an analytical method called PQ plane analysis with consideration of the reactive power capability of wind turbine generator and the wake effect of wind farm is proposed for voltage stability study. Two voltage stability indices based on the proposed PQ plane analysis method incorporating the uncertainties of load-increasing direction and wind generation are designed and implemented. Cases studies are conducted to investigate the impacts of wind power incorporation with different control modes. Simulation results demonstrate that the constant voltage control based on reactive power capability significantly enhances voltage stability in comparison of the conventional constant power factor control. Some meaningful conclusions are obtained.

In the desert and Gobi regions with strong wind and large sediment discharge, sand transporting engineering is more effective than sand blocking and sand fixing measures in sand prevention. This study uses the discrete phase model of 3D numerical simulation to study the motion trail, motion state and distribution rule of sand particles with different grain diameters when the included angle between the main shaft of the feather-row lateral transportation sand barrier and the wind direction changes, and conducts a comparison in combination with the wind tunnel test and the flow field rule of common sand barrier. According to the comparison, when wind-sand incoming flow passes through a feather-row sand barrier, sand particles slow down and deposit within the deceleration area under the resistance of the feather-row sand barrier, move along the transportation area formed by the transportation force, and accumulate as a ridge at the tail of the engineering. With increasing wind speed, the eolian erosion of the sand particles to the ground and the feather-row sand barrier is enhanced, and the sand transporting quantity and throw-over quantity of the feather-row sand barrier are both increased. When sand particles with different grain diameters bypass the feather-row sand barrier, the particle size of the infiltrating sands will increase with the included angle between the main shaft of the feather-row sand barrier and the wind direction. The obtained result demonstrates that, at a constant wind speed, the flow field formed is most suitable for the lateral transportation of the wind-drift flow when the included angle between the main shaft of the feather-row sand barrier lateral transportation engineering and the wind speed is less than or equal to 30°.
A Non-Greedy Puncturing Method for Rate-Compatible LDPC Codes
Lin Zhou,Wei-Cheng Huang,Rui Zhao,Yu-Cheng He 한국통신학회 2017 Journal of communications and networks Vol.19 No.1
In this paper, we propose a non-greedy punctur-ing method for constructing binary rate-compatible low-densityparity-check codes. First, we show that the recovery error prob-ability for a punctured variable node can be reduced by allocat-ing a small number of unpunctured variable nodes in the recoverytree. Then, we redefine the recovery tree according to the princi-ple of iterative decoding with the sum-product algorithm. The pro-posed non-greedy puncturing algorithm lies mainly in the dynam-ical minimization of the number of unpunctured variable nodes inthe redefined recovery tree for the punctured variable nodes. Fi-nally, simulation results show that the proposed puncturing algo-rithm outperforms the existing best puncturing algorithms in biterror rate performances of iterative decoding.
