1重磅!中国科学家NEJM发文报道非洲发现的首个耐青蒿素疟原虫显示文摘近日,由中国江苏寄生虫病研究所的曹俊领导的研究团队首次报道他们在非洲发现了一种可以耐受现有最好的抗疟疾药物青蒿素的疟原虫,使得人们对数年来为对抗这种每年危害数百万人的疾病付出的努力感到担忧。这项发现意味着非洲及东南亚地区现在都有这种蚊媒疾病的耐药疟原虫。Lu F Culleton R Zhang M 2017疾病监测2017,32,2:34
2Susceptibility variations of multiple origins of loess from the Ily Basin(NW China)显示文摘The magnetic susceptibility of loess from the Ily Basin,northwestern China shows maximum values in S0 paleosols but minimum values in other paleosols,the mechanism of which has been well debated.In this work,systematic magnetic measurements were made on a representative section from Neleke county.The results show that the loess horizons(L1,L2 and L3) have multi-domain magnetite grains of aeolian origin,S0 is characterized by production of pedogenetic ultrafine-grained ferrimagnetic minerals,and the other paleosols(S1,S2,and S3) are characterized by the formation of nonferrimagnetic minerals associated with waterlogging.The correlation between the low concentration of ferrimagnets,high paramagnetic content,high magnetic coercivity remanence,fine ferrimagnetic grain size and intensified pedogenesis suggest two competing processes of pedogenetic enhancement and pedogenetic depletion in the lower paleosols.Pedogenetic depletion dominates and is responsible for the low susceptibility.Changes in magnetic grain size distribution occur during pedogenetic depletion.The susceptibility variations are of multiple origins in the loess of the Ily Basin.Pedogenetic enhancement,pedogenetic depletion,and allochthonous input of magnetic minerals should all be taken into account to explain the variations of magnetic parameters.CHEN Qu LIU XiuMing HELLER F HIRT Ann M LU Bin GUO XueLian MAO XueGang ZHAO GuoYong FENG Hua GUO Hui 2012Chinese Science Bulletin2012,57,15:9
3Interoperability of Design Intent in Integrated Product and Process Design显示文摘Concurrent engineering is currently an overwhelming t rend in product development since it takes the down-stream product development issues and product life-cycle issues into consideration in up-front design pro cess. At this stage, evaluation, verification and validation of design concepts and design schemes is critical to the right-to-market product development. I dentification and extraction of design intent from the part digital mock-ups in different data formats and created in different CAD systems for DFX considerati on, evaluation, verification, and validation is crucial too. Traditionally, fro m manufacturing point of view, feature identification and extraction is to get t he features and feature-related information for manufacturing planning and inte gration. Presently, from the viewpoint of product development and product servi ce life cycle, design intent identification and extraction is to get all the des ign-related information for DFX consideration in early design stage, such as de sign for assembly, design for service, design for tooling, design for functional ity and design for environment etc. Therefore, how to successfully extract desi gn intent such as design and machining features and design-related information from the prototyping digital mock-ups created by different CAD systems for DFX consideration in upstream design stage is a very useful topic in integrated prod uct and process design and development. Presently, there are heterogeneous CAD systems in the market and the interoperat ion among the different CAD systems is indispensable. The interoperability of d ifferent CAD systems is by way of data exchanged technology such as STEP and IGE S. The critical weakness of this interoperation technology is that much of the design intent is lost in the interoperation process. Once the product digital m ock-ups is exchanged via data exchange technology such as IGES or STEP, the des ign intent including the dimension-driven design features and other attributes embedded in the part model are lost in the data translation process. Models rea d out of CAD systems come into other systems as featureless chunks of geometry e ntities. Obviously, the interoperation technology does not satisfy the industry need. It has been reported that this poor interoperation technology, which pro vides poor CAD models in neutral-format geometry had cost the automobile indust ry alone $1 billon per year. Fortunately, some researchers have been aware of t he criticality of this since only the United States industry spends billons of d ollars as a result of poor interoperability between computer-aided engineering software tools. In the past, product development was often done within a single company by co-located design team. In more recent years, there has been a busi ness paradigm shift in product development as the product development is being d one more often by geographically and temporally distributed design teams. There is a high level of outsourcing, not only of manufacturing but also of actual pr oduct development effort. Besides, product development across companies, and ev en within a single company, is often done within a heterogeneous software tool e nvironment. How to improve the interoperability of design intent created in het erogeneous software tool environment geographically has become a critical issue in next-generation product development system. Design intent in this research is defined as the outcome of design process. Des ign process goes from the identification of needs to satisfaction of that needs. Design intent satisfies this kind of needs. In this research, design intent i s created in a CAD system and embedded in part CAD model. The detailed design i ntent here includes design and manufacturing features and the feature-relat ed information such as feature parameters, feature relationships and some relate d characteristics such as associativity. Interoperability refers to the ability to share and communicate in the heterogeneous environment or heterogeneous softM W Fu W F Lu A Y C Nee S K Ong 2002厦门大学学报(自然科学版)2002,41,S1:2
