Background Plants have evolved excellent ability of flexibly regulating the growth of organs to adapt to changing environment, for example, the modulation of lateral root development in response to environmental stresses. Despite of fundamental discovery that some microRNAs are involved in this process, the molecular mechanisms of how these microRNAs work together are still largely unknown. Results...
By summarization of small and medium scale software development process practices to propose a CMM best practice in component-based system construction. This best practice not only ensures fast, reasonable, low cost software development process control, but also has distinct process control, can be rechecked and be understood. Adaptability adjustment is allowed during software process. By real case...
We present fully polynomial approximation algorithm for generalized maximum concurrent flow problem with budget constraint that run in time independent of the number of commodities k. We show that by modifying the algorithms by Karakostas and Fleischer. We can reduce their running time. At the same time the approximation solution of the new algorithm is closer to optimal value.
A Web Services based Online Training and Exam System is introduced and implemented in this paper. The system includes five modules which are System Management Module, Item Bank Management Module, Online Training Module, Online Exam Module and Statistical Analysis Module. And the design idea, the system architecture as well as the realizing methods of the system are also introduced in detail.
