- The jiuding Ridge (Sichuan, China) has been explored during the past several years by a team from chengdu Institute of Biology. Chinese Academy of Sciences, and three undescribed species of Corydalis DC. (Fumariaceae) have been revealed and are apparently endemic to this mountain. The new species were observed in forest (C. capitata X.F. Cao, Liden & Y.W. Wang), and alpine rocky limestone areas (C. schistostigma X.F. Cao, Liden, Y.W. Wang & Y.L. Peng). The two first species have their closest relatives in the Wolong-Balangshan District in the Wolong-Balangshan District (Wenchuan. Sichuan). Corydalis aeaeae differs from C. panada Liden & Y.W. Wang in its small size, few-flowered racemes, and broadly obtuse outer petals with low, short erests. Corydalis capitata differs from the C. flexuosa Franchet complex in the capitate racemes, small flowers with deeply serrate petals, and the peculiar, thin, strictly ecect lateral branches. corydalis schistostinma is unique in the C. curviflora Maximowicz ex Hemsley group, in the deeply cleft stigma and very forward-projecting crests to the inner petals, and possibly has iits affinities more to the north and northwest in the Hengduan Mountains.

- In the cloud computing era, service provider cloud and context service cloud store all your personal context data. This is a positive aspect for value-added context-aware service cloud as it makes that context information collection are easier than was the case previously. However, this computing environment does add a series of threats in relation to privacy protection. Whoever receives the context information is able to deduce the status of the owners and, generally owners are not happy to share this information. In this paper, we propose a privacy preserved framework which can be utilized by value-added context-aware service cloud. Context data and related services access privileges are determined by context-aware role-based access control (CRAC) extended from role-based access control (RAC). Privacy preserved context service protocol (PPCS) is designed to protect user privacy from exposed context information. Additionally, user network and information diffusion is combined to evaluate the privacy protection effect.
