In this paper, the adaptive bipartite output containment problem is investigated, for a signed graph of heterogeneous multi-agent systems (HMASs). An adaptive state feedback algorithm and an output feedback algorithm are designed to ensure that cooperative and antagonistic agents enter different convex hull. A novel protocol is proposed for heterogeneous systems to deal with the bipartite output containment problem, where only the leader’s neighbours can learn the leader’s system matrix without all followers. Then, based on output regulation approach, Lyapunov stability analysis and some other methods guarantee that the bipartite output containment control problem is implemented. Finally, the validity of our analytical results is verified by the numerical simulations provided.

Risk-informed safety classification of structures, systems and components (SSCs) is very important forensuring the safety and economic efficiency of nuclear power plants (NPPs). However, previous methodsfor safety classification of SSCs do not take the plant operating modes or the operational process of SSCsinto consideration, thus cannot concentrate on the safety and economic efficiency accurately. In thiscontribution, a new method for safety classification of SSCs based on the categorization of plant operating modes is proposed, which considers the NPPs operating history to improve the economic efficiencies while maintaining the safety. According to the time duration of plant configurations in plantoperating modes, average importances of SSCs are accessed for an NPP considering the operationalprocess, and then safety classification of SSCs is performed for plant operating modes. The correctnessand effectiveness of the proposed method is demonstrated by application in an NPP's safety classificationof SSCs

<P>Thermoresponsive biopolymeric microstructures are prepared by exploiting the thermal phase transitions of emulsified elastin-like polypeptides (ELPs). ELP microbeads prepared below the transition temperature (<I>T</I><SUB>t</SUB>) have positively thermoresponsive pores. ELP microcapsules prepared above <I>T</I><SUB>t</SUB> have negatively thermoresponsive pores. Interestingly, the ELP microcapsules prepared at the temperature of the transition state displayed bidirectional thermoresponsive behavior.</P> <P>Graphic Abstract</P><P>The responsiveness and morphology of ELP microstructures were controlled through the temperature used during the crosslinking process in an emulsion. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3cc49044k'> </P>
A Study on the Corporate Culture of Tongrentang

The importance of corporate culture for its development has always been a classic research. Through excellent corporate culture, we can analyze the secrets of company success and provide important reference significance for other company brands. Since the outbreak of COVID-19, Traditional Chinese Medicine (TCM) has greatly increased its international recognition with its excellent efficacy, which has brought development opportunities to the TCM industry. The object of this research is the Beijing Tongrentang Group Co., Ltd. Tongrentang is a representative of Chinese time-honored brands in TCM industry. It has a development history of more than 350 years. It carries the traditional Chinese culture and Chinese medicine culture. The corporate culture of Tongrentang was thus extended and developed into 'Benevolence & love', 'Honesty & trustworthiness' and 'Quality first'. We can see that a good corporate culture is particularly important. This paper studies the unique Corporate culture of Tongrentang, and the reasons of company success. Hoping to help the company through this pap
Bicluster and Pathway Enrichment Analysis of HCV-induced Cirrhosis and Hepatocellular Carcinoma

Background: Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the most common form of liver cancer. However, while it is associated frequently with hepatitis C virus (HCV) there is only an elementary understanding of its molecular pathogenesis. Methods: To gain insight into the molecular mechanisms of HCV-induced hepatocarcinogenesis, we performed microarray analysis on 75 surgical liver samples from 48 HCV-infected patients. Results: There were 395 differentially expressed geness between cirrhotic samples and HCC samples. Of these, 125 genes were up-regulated and 270 genes were down-regulated. We performed pathway enrichment analysis and screened as described previously. Conclusions: The differentially expressed genes might be involved in hepatocarcinogenesis through upregulating the pathways of ECM-receptor interaction, focal adhesion, cell adhesion molecules and other cancer-related pathways, and downregulating the pathways of "complement and coagulation cascades". We hope our results could aid in seeking of therapeutic targets for HCV-induced hepatocellular carcinoma.

To gain an insight into the function of heat shock proteins (HSPs) in insects during thermal stress, three HSP cDNAs were identified in the transcriptome of adult Heortia vitessoides, one of the most destructive defoliating pests in Aquilaria sinensis (Loureiro) Sprenger forests. The open reading frames of HvHsp60, HvHsp70, and HvHsp90 were 1,719, 2,070, and 2,151 bp in length, respectively, and encoded proteins with molecular weights of 61.05, 75.02, and 82.23 kDa, respectively. Sequence analysis revealed that all three HSPs were highly conserved in structure. Regarding the stage‐specific expression profiles, HvHsp60, HvHsp70, and HvHsp90 mRNAs were detected in all developmental stages. Regarding the tissue‐specific expression profiles, the expression levels of the three HSP genes were different in various larval and adult tissues. Moreover, the expression patterns of heat‐stressed larvae, pupae, and adults indicated that HvHsp60, HvHsp70, and HvHsp90 were heat‐inducible. In particular, HvHsp60 transcripts increased dramatically in larvae and pupae that were heat‐stressed at 40°C and were upregulated in adults that were heat‐stressed at 35°C and 40°C. The expression of HvHsp70 significantly increased in all of the three different developmental stages at 35°C, 40°C, and 45°C. The expression of HvHsp90 obviously increased at 30°C, 35°C, and 40°C in larvae and could be induced at 35°C in pupae and adults. The results suggest that HSP60, HSP70, and HSP90 play a major role in protecting H. vitessoides against high‐temperature stress.
