软件过程是人和计算机化的工具交互完成的可能持续长时间的复杂实体。软件过程比商业过程自动化程度要低,因为需要更多的人的参与和软件工具的支持,也有更多不断持续改进的需求。软件过程首先要建模,因此建模语言扮演了一个非常关键的角色。从管理的角度出发,CMM提出了一个软件过程概念框架。既要支持软件过程语言的要求的特性,又要支持CMM,基于CMM的软件过程定义语言必须把这个一般性和特殊性的要求结合起来。本文描述的软件过程定义语言CSPDL采用了图形和XML文本相结合的表示方式。同时,软件过程定义工具是支持建模的必需的支持。要尽量地支持软件过程语言的特性,还需要很多工作要做。

种子活力在发育中逐渐形成,成熟期随着水分的减少,种子获得最大活力。期间发生了许多重要的生理生化反应,如营养物质大量积累、酶和mRNA的钝化等,为种子活力的保持和萌发做好准备。植物中有20%~30%的核基因组DNA胞嘧啶处于甲基化状态,DNA甲基化可以调节基因的表达,维持植物基因组稳定。而植物的DNA甲基化状态在不同器官、不同组织、甚至发育的不同阶段都是不同的,这与遗传和外界环境的刺激相关。在种子的活力形成和萌发过程中,DNA甲基化状态也发生了复杂的变化,这种变化具有种属特异性。种子活力的遗传基础复杂,且受到环境因素的影响。种子经历逆境胁迫时,DNA甲基化状态会发生改变,种子活力水平也会下降,这可能是由于逆境胁迫相关基因的DNA甲基化状态发生变化引起的。

Selective modification of peptides has always been a challenging issue. The selective alkylation of peptides can alter the biological activity and physical properties of molecules, and it has gained significant research interest. We herein disclose an intriguing gold-catalyzed alkylation of peptides using bench-stable unactivated alkyl bromides under photoredox catalysis. A wide range of structurally diverse primary, secondary and tertiary alkyl bromides serve as effective coupling partners to precisely connect with the α-C(sp3)–H in glycine residue of peptides. This protocol demonstrates an exceptionally broad scope for alkyl halides and excellent tolerance for a wide range of useful functional groups. A series of relay transformations to construct cyclic peptides, to proceed click reaction and to realize peptide fluorescence labeling further enhance its synthetic practicality. In addition, mechanistic studies and density functional theory(DFT) calculations reveal an inner-sphere and subsequent outersphere single electron transfer(SET) mechanism.

Based on the geochemical prospecting data, we have calculated the gamma absorbed dose rates in air 1 m above the ground surface in the Chengdu Plain, analyzed the relationship between the geological conditions and the distribution of the natural radionuclides, and preliminarily studied the influence of the geological conditions on the terrestrial radiation level in the Chengdu Plain. The result shows that the terrestrial radiation level in the Chengdu Plain is slightly lower than the average values of China and varies greatly according to the complex geological conditions.

Product innovation is creation of new concepts to plan and realize technological and functional details in the product to satisfy market and customer needs. One of the key drivers to product innovation is reactions of the product to users’ needs. Product innovation needs a cognitive design method based on needs of variant users for the product personalization. In this paper, an open concept is introduced to provide ways to meet user’s individual need in product lifespan. It is for industries to propose product concepts based on open sources, develop and support the product on the public capability. Using the open concept in the product architecture, called open?architecture product(OAP), can improve the product personalization leading to massive product innovation. To promote this promise of the OAP, effective methods are discussed for the OAP development. This paper introduces research on OAPs using adaptable design methods to meet product personalization. Adaptable design is based on the modular structure for product adaptability using function modules and adaptable interfaces. The proposed method provides solutions for planning modules and implementation of OAPs. Methods of OAP module planning, detail and interface design are described for transformation of product concepts into physical structures. A multiple?purpose electrical car is developed in a case study to show effectiveness of the proposed method.
