摘要： The increasing trend of global energy demand due to rising population,comfort expectations and living standards has caused a prevalent concern about the state of the supply-demand chain of energy in the upcoming years.Considering that the building sector is responsible for about one-third of the final energy demand and related greenhouse gas emissions,it is important to take actions in order to reduce the energy demand of building sector and consequent release of greenhouse gas emissions[1].Moreover,energy need of the globe is expected to be doubled by 2050.

摘要： There’s a lot of value in data.The collection,fusion and mining of multi-source data will release the potential of data and bring into play the value of data.At the same time,due to their respective interests and risks of privacy exposure,there are obstacles in the development of mul­ti-data fusion,and the phenomenon of“isolated data is­land”is common,which hinders the development of data fusion.

摘要： On Apr 12,at a release ceremony jointly held by the Institutes of Science and Development of Chinese Academy of Sciences,Chinese Academy of Sciences(CASISD)and Springer Nature,the report New Energy Technology Research—Opportunities and Challenges went public.

摘要： The hepatitis C virus(HCV),an obligatory intracellular pathogen,highly depends on its host cells to propagate successfully.The HCV life cycle can be simply divided into several stages including viral entry,protein translation,RNA replication,viral assembly and release.Hundreds of cellular factors involved in the HCV life cycle have been identified over more than thirty years of research.Characterization of these cellular factors has provided extensive insight into HCV replication strategies.Some of these cellular factors are targets for anti-HCV therapies.In this review,we summarize the well-characterized and recently identified cellular factors functioning at each stage of the HCV life cycle.

摘要： Nanomaterial-based drug sustainable release systems have been tentatively applied to bone regeneration.They,however,still face disadvantages of high toxicity,low biocompatibility,and low drug-load capacity.In view of the low toxicity and high biocompatibility of polymer nanomaterials and the excellent load capacity of hollow nanomaterials with high specific surface area,we evaluated the hollow polydopamine nanoparticles(HPDA NPs),in order to find an optimal system to effectively deliver the osteogenic drugs to improve treatment of bone defect.Data demonstrated that the HPDA NPs synthesized herein could efficiently load four types of osteogenic drugs and the drugs can effectively release from the HPDA NPs for a relatively longer time in vitro and in vivo with low toxicity and high biocompatibility.Results of qRT-PCR,ALP,and alizarin red S staining showed that drugs released from the HPDA NPs could promote osteogenic differentiation and proliferation of rat bone marrow mesenchymal stem cells(rBMSCs)in vitro.Image data from micro-CT and H&E staining showed that all four osteogenic drugs released from the HPDA NPs effectively promoted bone regeneration in the defect of tooth extraction fossa in vivo,especially tacrolimus.These results suggest that the HPDA NPs,the biodegradable hollow polymer nanoparticles with high drug load rate and sustainable release ability,have good prospect to treat the bone defect in future clinical practice.

摘要： 一种用于将在后模具部分(21)和前模具部分(22)之间的腔中模制的并且粘附于其上的透镜脱开的装置和方法。将柱(30)设置为支承后部分的凸缘(20)，同时前部分保持与该柱分开。后部分在施加于后部分的外凹面(29a)的销(40)与该柱之间受到挤压，从而最初使后部分的外围区域脱开，随后使其余部分脱开。在分离之后，前部分连同透镜(10)下降到该柱上，从而使其外凸面(29a)置于该柱上。具有气体通道(53)的套环单元(50)压住前部分的凸缘(200)，同时气体射流朝该透镜周围形成的“单体”环(11)之间的界面吹气。按照这种方式，最初是“单体”环然后是透镜的外围区域与前部分分开。

摘要： 本发明涉及一种涉及信誉值机制的基于Gradual Release的公平交换方法，其特征在于，当系统中任意两交换方准备进行交换时，将首先根据系统中对方的信誉值决定是否交换。双方都同意交换后，就采用基于Gradual Release的交换方法对信息分片，然后逐步传输信息分片。传输结束后，参与交换的双方都将对对方在此次交换中的行为进行评分，并作为交换参与者的一部分信誉记录保存在本地。信息分片数由交换双方中信誉值较低的一方的信誉值决定。本方法通过将信誉值机制引入公平交换，一方面改进了Gradual Release的公平交换方法，极大地提高了高信誉值用户进行公平交换的效率；另一方面采用信誉值机制在不需要第三方参与的情况下激励交换双方尽可能的遵守协议，减少破坏协议公平性行为的发生。同时在交换双方具体进行交换时，将由信誉值较低的一方首先发出自己的信息分片，在一定程度上解决了原有Gradual Release的“最后一比特的不公平性”问题。本发明适用于难于找到TTP或者希望花费较少代价即可进行公平交换的场合。
