面向Agent的需求分析环境

提出了一种面向Agent的信息处理模型及其支撑环境.该模型将客观世界中具有信息处理能力的自主实体视为Agent,通过对Agent的自主行为及它们之间协同工作的描述,建立信息处理过程的模型.由于该建模方法与人们认识现实世界的方法一致,因此,基于该模型的支撑环境更容易适应现实世界.

Supply Network Structure,Visibility, and Risk Diffusion: A Computational Approach

Understanding and managing supply chain risks is a critical functional competency for today's global enterprises. A lack of this competency can have significant negative outcomes, including costly production and delivery delays, loss of future sales, and a tarnished corporate image. The ability to identify and mitigate risks, however, is complicated as supply chains are becoming increasingly global, complex, and interconnected. Drawing on the complex systems and epidemiology literature, and using a computational modeling and network analysis approach, we examine the impact of global supply network structure on risk diffusion and supply network health and demonstrate the importance of supply network visibility. Our results show a significant association between network structure and both risk diffusion and supply network health. In particular, our results indicate that small‐world supply network topologies consistently outperform supply networks with scale‐free characteristics. Theoretically, our study contributes to our understanding of risk management and supply networks as complex networked systems using a computational approach. Managerially, our study illustrates how decision makers can benefit from a network analytic approach to develop a more holistic understanding of system‐wide risk diffusion and to guide network governance policies for more favorable health level outcomes. The article concludes by highlighting the main findings and discussing possibilities of future research directions.     

二维凝胶体系中生物分子及络合剂对草酸钙晶体生长的影响

在二维凝胶体系中加入生物分子及络合剂诱导草酸钙晶体生长，采用XRD、FTIR拍摄晶体形貌，并对其进行表征。结果表明：在分别加入植酸、尿酸、天冬氨酸的体系中都出现了COM、COT和COD的晶型晶体，对比没有加入这些生物分子的体系，COM的量明显降低，COD的量显著增加，且COD主要沿着（222）面生长。而在分别加入柠檬酸钠、乙二胺四乙酸钠和葡萄糖的体系中只存在COT和COD晶型晶体，说明它们在一定条件下可以抑制尿结石主要成分COM的形成。     

Agent‐Based Simulation for Human‐Induced Hazard Analysis

Terrorism could be treated as a hazard for design purposes. For instance, the terrorist hazard could be analyzed in a manner similar to the way that seismic hazard is handled. No matter how terrorism is dealt with in the design of systems, the need for predictions of the frequency and magnitude of the hazard will be required. And, if the human‐induced hazard is to be designed for in a manner analogous to natural hazards, then the predictions should be probabilistic in nature. The model described in this article is a prototype model that used agent‐based modeling (ABM) to analyze terrorist attacks. The basic approach in this article of using ABM to model human‐induced hazards has been preliminarily validated in the sense that the attack magnitudes seem to be power‐law distributed and attacks occur mostly in regions where high levels of wealth pass through, such as transit routes and markets. The model developed in this study indicates that ABM is a viable approach to modeling socioeconomic‐based infrastructure systems for engineering design to deal with human‐induced hazards.     

论身体行为句式

身体行为句式是汉语里的一种常见句式,其基本结构模式为"n1+v+n2",例如"他摇了摇头"。句子中通常有两个名词,一个指人,一个指人身体的某部分。句中的动词和名词之间的语义关系特别是施受关系比较特殊。身体行为句式属于可变换句式,句式之间的变换形式丰富多样。
