Background The invasion success of introduced freshwater fishes is influenced by many factors, including ecological, species, and socioeconomic characteristics. Most studies that document the importance of these characteristics are conducted at local scales and/or focus on a single step of the invasion process. In this study, we aim to determine the species characteristics, ecological characteristics, and socioeconomic characteristics of non-native freshwater fish invasions. Our assessment was done at the global scale and considers all three steps of the invasion(i.e., introduction, establishment, and impact). For this purpose, we applied generalized linear models to 20 variables collected for 307 non-native species and modeled them as a function of ecological characteristics(i.e., environmental features), species traits(i.e., functional and morphological), and socioeconomic characteristics(i.e., human use and introduction pathways). We considered the number of countries in which each species was introduced, established, or had ecological impacts as a proxy of invasion step success. We also explored the specifics of species introduced through the aquaculture and the ornamental fish trade *** We found that non-native freshwater fishes with broad diets, high parental care, and multiple introduction pathways are the most widely introduced and established worldwide. The number of countries with impacts reported was best explained by the type of introduction pathway(i.e., aquaculture or fisheries). Moreover, among non-native species introduced through aquaculture, those belonging to cypriniformes and having broad diets were the most widely introduced and established species. In contrast, the species introduced through the ornamental fish trade pathway belonged to various taxonomic orders but were mainly native to tropical *** considering several types of factors is important when analyzing the invasion success of freshwater fish and disentang

The development and application of systems strategies to biology and disease are transforming medical research and clinical practice in an unprecedented rate. In the foreseeable future, clinicians, medical researchers, and ultimately the consumers and patients will be increasingly equipped with a deluge of personal health information, e.g., whole genome sequences, molecular profiling of diseased tissues, and periodic multi-analyte blood testing of biomarker panels for disease and wellness. The convergence of these practices will enable accurate prediction of disease susceptibility and early diagnosis for actionable preventive schema and personalized treatment regimes tailored to each individual. It will also entail proactive participation from all major stakeholders in the health care system. We are at the dawn of predictive, preventive, personalized, and participatory （P4） medicine, the fully implementation of which requires marrying basic and clinical researches through advanced systems thinking and the employment of high-throughput technologies in genomics, pro- teomics, nanofluidics, single-cell analysis, and computation strategies in a highly-orchestrated discipline we termed translational systems medicine.

本研究旨在调查法国和中国消费者的购买决策。研究重点是两个方面,一方面是天然化妆品,另一方面是这些产品的起源国。如今,越来越多的消费者对其化妆品的质量是敏感的。越来越多的公共卫生问题导致消费者更多地考虑他们正在购买什么以及他们在皮肤上的含量。消费者更倾向于购买天然化妆品,而不是购买含有源自石油化学品的物质的传统化妆品。为了回应消费者的不断变化的行为,制造公司特别重视开发包含有较少化学物质和更多的自然元素的化妆品。增加公众健康关注使消费者更多地考虑他们正在购买什么以及他们把什么物质放在皮肤上。代替购买含有源自石化产品的传统化妆品,消费者更倾向于购买天然化妆品。这项研究特别考察了一个具体因素,这是这些天然化妆品的起源国。原产国的重要性在消费者的购买决定中起着重要作用,但这一重要性尚待确定。法国消费者被选中是因为法国天然化妆品市场不断增长。如今,法国天然化妆品品牌在全球知名,在全球天然化妆品市场享有很高的声誉。此外,法国天然化妆品市场是发达的,并且强烈地存在于法国消费者的心中。中国消费者也因为中国化妆品市场不断上涨而得到分析。越来越多的品牌正在推出自已的天然化妆品,以吸引客户。这项研究的目的是阐明法国和中国消费者购买行为和原产地国家的形象之间的关系。研究工作强调了天然化妆品生产国的重要性,与其他四个主要标准相比。然后本文旨在比较影响法国和中国消费者购买决策的因素。为了测试该假设,在法国和中国消费者中进行了问卷调查。抽样调查人员来自居住在法国和中国的男性和女性客户。调查问卷包含了首先评估天然化妆品原产国重要性的答案,与其他四项主要标准进行比较,其次是比较法国和中国消费者眼中起源国的重要性。研究的结果在研究的第四部分进行了描述,其中分析了获得的数据并支持或拒绝了假设。

In this paper numerical analysis of underground structures, taking account the transverse isotropy system of rocks, was done using cAST 3M code by varying the shape of excavation and the coefficient of earth pressure k. Numerical results reveal that the anisotropy behavior, the shape of hole and the coefficient of earth pressure k have significant influence to the mining induced stress field and rock deformations which directly control the stability of underground excavation design. The magnitude of horizontal stress obtained for the horse shoe shape excavation(25.2 MPa for k = 1; 52.7 MPa for k = 2)is lower than the magnitude obtained for circular hole(26.4 MPa for k = 1; 59.5 MPa for k = 2).Therefore, we have concluded that the horse shoe shape offers the best stability and the best design for engineer. The anisotropy system presented by rock mass can also influence the redistribution of stresses around hole opened. Numerical results have revealed that the magnitude of redistribution of horizontal stresses obtained for transverse isotropic rock(12.1 MPa for k = 0.5; 25.2 MPa for k = 1 and52.7 MPa for k = 2) is less than those obtained in the case of isotropic rock(27.6 MPa for k = 1;48.6 MPa for k = 2 and 90.81 MPa for k = 2). The more the rock has the anisotropic behavior, the more the mass of rock around the tunnel is stable.

The temporal behaviour of a flow separation in the hub-suction side comer of a transonic diffuser is studied thanks to unsteady numerical simulations based on the phase-lagged approach. The validity of the numerical re- sults is confn＇med by comparison with experimental unsteady pressure measurements. An analysis of the instan- taneous skin-friction pattern and particles trajectories is presented. It highlights the topology of the separation and its temporal behaviour. The major result is that, despite of a highly time-dependent core flow, the separation is found to be a ＂fixed unsteady separation＂ characterized by a fixed location of the main saddle of the separation but an extent of the stall region modulated by the pressure waves induced by the impeller-diffuser interaction.
