| 1 | Multi-dimensional scenario forecast for generation of multiple wind farms显示文摘A novel multi-dimensional scenario forecast approach which can capture the dynamic temporal-spatial interdependence relation among the outputs of multiple wind farms is proposed.In the proposed approach,support vector machine(SVM)is applied for the spot forecast of wind power generation.The probability density function(PDF)of the SVM forecast error is predicted by sparse Bayesian learning(SBL),and the spot forecast result is corrected according to the error expectation obtained.The copula function is estimated using a Gaussian copula-based dynamic conditional correlation matrix regression(DCCMR)model to describe the correlation among the errors.And the multidimensional scenario is generated with respect to the estimated marginal distributions and the copula function.Test results on three adjacent wind farms illustrate the effectiveness of the proposed approach. | Ming YANG You LIN Simeng ZHU Xueshan HAN Hongtao WANG | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，3： | 10 |
| 2 | “Three medicines and three formulas”in COVID-19:from bench to bedside显示文摘Chinese guideline has proven effective in the fight against coronavirus disease 2019(COVID-19)during the global spread of the epidemic.Traditional Chinese medicine(TCM)is widely recognized for its effectiveness in alleviating symptoms,inhibiting disease progress,reducing mortality,and improving the cure rate of patients with COVID-19.During the pandemic,“three medicines and three formulas”(TMTFs)stood out from hundreds of others in registered clinical studies,which became highly recommended as TCM for COVID-19 treatment.The TMTFs not only effectively relieve the clinical symptoms of fever,cough,fatigue,and phlegm,but also substantially shorten the time of nucleic acid negative conversion,improve lung computed tomography imaging features and inflammation,ameliorate clinical biochemical indicators,and reduce sequelae.Their potential pharmacological mechanisms are mainly related to the crosstalk between viral toxicity,endothelial damage,cytokine storm,immune response,and microthrombus.In brief,the clinical effects and the potential mechanisms of TMTFs on COVID-19 were systematically analyzed and summarized covering the entirety of disease development,including virus invasion and replication,immune response and cytokine storm,and acute respiratory distress syndrome and multiple organ dysfunction syndrome.This review provides a theoretical basis and reference for the in-depth understanding of the positive role of TMTFs in COVID-19 treatment. | Guangxu Xiao Simeng Wang Ruijiao Wang Li Tan Shibo Ma Shuang He Guanwei Fan Yan Zhu Ming Lyu | 2023 | Acupuncture and Herbal Medicine2023，3，4： | 1 |
| 3 | Dietary resistant starch alleviates Escherichia coli-induced bone loss in meat ducks by promoting short-chain fatty acid production and inhibiting Malt1/NF-κB inflammasome activation显示文摘Background:Escherichia coli(E.coli)infection in humans and animals usually comes with gut dysbiosis,which is potential culprit to skeletal health,it is still unclear to whether diet interfered gut microbiome changes can be a protective strategy to bone loss development.Here,the effects of resistant starch from raw potato starch(RPS),a type of prebiotic,on E.coli-induced bone loss and gut microbial composition in meat ducks were evaluated.Results:The results showed that dietary 12%RPS treatment improved bone quality,depressed bone resorption,and attenuated the pro-inflammatory reaction in both ileum and bone marrow.Meanwhile,the 12%RPS diet also increased the abundance of Firmicutes in E.coli-treated birds,along with higher production of short-chain fatty acids(SCFAs)especially propionate and butyrate.Whereas addition ofβ-acid,an inhibitor of bacterial SCFAs production,to the drinking water of ducks fed 12%RPS diet significantly decreased SCFAs level in cecum content and eliminated RPS-induced tibial mass improvement.Further,treatment with MI-2 to abrogate mucosa-associated lymphoid tissue lymphoma translocation protein 1(Malt1)activity replicated the protective role of dietary 12%RPS in E.coli-induced bone loss including reduced the inhibition on nuclear factorκB(NF-κB)inflammasome activation,decreased bone resorption,and improved bone quality,which were correlated with comparable and higher regulatory T cells(Treg)frequency in MI-2 and 12%RPS group,respectively.Conclusions:These findings suggested that the diet with 12%RPS could alleviate E.coli-induced bone loss in meat ducks by changing the gut microbial composition and promoting concomitant SCFAs production,and consequently inhibiting Malt1/NF-κB inflammasome activation and Treg cells expansion. | Huaiyong Zhang Simeng Qin Xiangli Zhang Pengfei Du Yao Zhu Yanqun Huang Joris Michiels Quifeng Zeng Wen Chen | 2023 | Journal of Animal Science and Biotechnology2023，14，1： | 0 |
| 4 | Stacking monolayers at will:A scalable device optimization strategy for two-dimensional semiconductors显示文摘In comparison to monolayer(1L),multilayer(ML)two-dimensional(2D)semiconducting transition metal dichalcogenides(TMDs)exhibit more application potential for electronic and optoelectronic devices due to their improved current carrying capability,higher mobility,and broader spectral response.However,the investigation of devices based on wafer-scale ML-TMDs is still restricted by the synthesis of uniform and high-quality ML films.In this work,we propose a strategy of stacking MoS_(2) monolayers via a vacuum transfer method,by which one could obtain wafer-scale high-quality MoS_(2) films with the desired number of layers at will.The optical characteristics of these stacked ML-MoS_(2) films(>2L)indicate a weak interlayer coupling.The stacked MLMoS_(2) phototransistors show improved optoelectrical performances and a broader spectral response(approximately 300-1,000 nm)than that of 1L-MoS_(2).Additionally,the dual-gate ML-MoS_(2) transistors enable enhanced electrostatic control over the stacked ML-MoS_(2) channel,and the 3L and 4L thicknesses exhibit the optimal device performances according to the turning point of the current on/off ratio and the subthreshold swing. | Xiaojiao Guo Honglei Chen Jihong Bian Fuyou Liao Jingyi Ma Simeng Zhang Xinzhi Zhang Junqiang Zhu Chen Luo Zijian Zhang Lingyi Zong Yin Xia Chuming Sheng Zihan Xu Saifei Gou Xinyu Wang Peng Gong Liwei Liu Xixi Jiang Zhenghua An Chunxiao Cong Zhijun Qiu Xing Wu Peng Zhou Xinyu Chen Ling Tong Wenzhong Bao | 2022 | Nano Research2022，15，7： | 0 |
| 5 | Dietary zero-dimensional fullerene supplementation improves the meat quality,lipid metabolism,muscle fiber characteristics,and antioxidative status in finishing pigs显示文摘With the increasing demand for high-quality pork,more nutritional substances have been studied for the regulation of meat quality.Zero-dimensional fullerenes(C60)can modulate the biological behavior of a variety of cell lines and animals.In this study,we report the biological effects of C60 on finishing pigs at different concentrations.A total of 24 barrows(Duroc×Large White×Landrace),with an average body weight of 21.01±0.98 kg,were divided into 3 groups and each treated daily with C60(100 or 200 mg per kg feed)or a control diet until the end of the experiment.Our results showed that dietary C60 supplementation improved flesh color,marbling scores,and flavor amino acid contents of longissimus dorsi(LD)of growing-finishing pigs(P<0.05).C60 improved meat quality by regulating lipid metabolism and muscle fiber morphology by mediating the expression of genes,L-lactic dehydrogenase(LDH),myosin heavy chain(MyHC)IIa,MyHCIIb,peroxisome proliferator-activated receptor γ(PPARγ),and fatty acid transport protein 1(FATP1)(P<0.05).Moreover,C60 substantially promoted the mRNA expression of antioxidant enzyme genes(P<0.05),which also contributed to improving meat quality.These findings have important implications for the application of C60 in the livestock industry,especially for improving the meat quality of fattening pigs. | Simeng Liao Guang Liu Bie Tan Ming Qi Xin Wu Jianjun Li Xiaoqing Li Changfeng Zhu Jiamei Huang Shuo Zhang Yulong Tang Yulong Yin | 2022 | Animal Nutrition2022，，4： | 0 |
| 6 | Temperature/pH dual-responsive reversible morphology evolution of block copolymer microparticles under three-dimensional confinement显示文摘Development of block copolymer(BCP)microparticles with switchable morphology in response to external stimuli is important for exploiting new intelligent materials.In this work,thermo/p H dual-responsive nanoparticles(NPs)were employed as a cosurfactant to modulate the self-assembly morphology of polystyrene-b-poly(2-vinylpyridine)(PS-b-P2VP)microparticles within confined emulsion droplets.The co-surfactant was synthesized by grafting poly(acrylic acid)-b-poly(N-isopropylacrylamide)onto the surface of Fe3O4NP.The introduction of the dual-responsive co-surfactant enabled thermo/p H dual-responsive reversible morphology transition of the PS-b-P2VP microparticles by tailoring the hydrophobicity and interfacial affinity of the cosurfactant.By using this strategy,the thermo-inert PS-b-P2VP self-assembled into pupa-like microparticles at T=10℃ and p H7.5,which could transform into tulip-like microparticles when T was increased to 50℃.When the p H value was increased to 11,the pupa-like particles turned into onion-like microparticles although the PS-b-P2VP was inert to alkali.However,the pupa-like microparticles remained unchanged when both T and p H were simultaneously increased.The PAA-b-PNIPAM-grafted Fe3O4NP surfactants showed obvious advantages over the linear PAA-b-PNIPAM surfactants in modulating the morphology transition,since the linear PAA-b-PNIPAM could not induce the reversible shape transition of microparticles.Our work provides an efficient strategy to achieve reversible shape transformation of BCP microparticles while the internal phase structure is preserved,which may be utilized to switch the structural color properties of BCP microparticles. | Mengmeng Zhang Zaiyan Hou Simeng Liu Guoqiang Han Meirong Tian Jintao Zhu Jiangping Xu | 2023 | Science China Chemistry2023，66，12： | 0 |
