数字保存的经济属性解析

作为一种经济产品,数字保存具有基本经济属性和核心经济属性。数字保存的基本经济属性是供给与需求,影响数字保存基本经济属性的因素有数字资源的保存价值、保存决策者的保存动机以及数字保存利益相关方承担的保存职责。数字保存的核心经济属性包括数字保存是一种派生需求、数字保存对象是一种价值递减产品、数字保存对象是一种非排斥性消费产品、数字保存是一种路径依赖性过程。

Amplification of SPPS150 and Salmonella typhi DNA with a high throughput oscillating flow polymerase chain reaction device

In this paper, a novel oscillating flow polymerase chain reaction (PCR) device was designed and fabricated to amplify SPPS150 and salmonella typhi. In this new design, the samples are shuttled (oscillating flow) inside a microfluidic chip to three different temperature zones required for DNA amplification. The amplification cycle time has markedly been reduced as the reagent volume used was only about 25% of that used in conventional PCRs. Bubble formation and adsorption issues commonly associated to chip based PCR were also eliminated. Based on the performance evaluated, it is demonstrated that this oscillating flow PCR has the advantages of both the stationary chamber and continuous flow PCR devices.

Synchronization within synchronization: transients and intermittency in ecological networks

Transients are fundamental to ecological systems with significant implications to management, conservation and biological control. We uncover a type of transient synchronization behavior in spatial ecological networks whose local dynamics are of the chaotic, predator–prey type. In the parameter regime where there is phase synchronization among all the patches, complete synchronization (i.e. synchronization in both phase and amplitude) can arise in certain pairs of patches as determined by the network symmetry—henceforth the phenomenon of  ‘synchronization within synchronization.’ Distinct patterns of complete synchronization coexist but, due to intrinsic instability or noise, each pattern is a transient and there is random, intermittent switching among the patterns in the course of time evolution. The probability distribution of the transient time is found to follow an algebraic scaling law with a divergent average transient lifetime. Based on symmetry considerations, we develop a stability analysis to understand these phenomena. The general principle of symmetry can also be exploited to explain previously discovered, counterintuitive synchronization behaviors in ecological networks.

中学数学课堂创新教学的思考

现代教学理论认为,数学课堂教学的本质是教师与学生、学生与学生之间以数学知识为媒介进行的一种沟通与交流,教师应树立“教学活动”的观念,围绕学生的学习活动和培养学生的问题意识设计教学、开放教学,切实让学生成为课堂的主人,让课堂焕发出生命的活力。课堂教学是实施素质教
