Analyzing the ploidy levels of plants is important for identifying species, selecting parental lines, identifying the relationships between species, and determining evolutionary patterns. The genus Chrysanthemum is widely distributed throughout the world and exhibits different ploidy levels. We used flow cytometry to analyze the ploidy levels of nine species of Chrysanthemum L. collected from different regions and geographical locations in China. Three diploids from Henan and Wuhan provinces corresponded to Chrysanthe- mum lavandulifolium and two species of C. nankingense, while three tetraploids from various regions corresponded to C. indicum and two species of C. chanetii. Two hexaploids corresponding to C. vestitum were collected at Funiu moun- tain （Henan province）, and C. zawadskii was collected at Huangshan mountain （Anhui province）. We found that OTTO extraction buffer was suitable for extracting nuclei from most species, apart from C. zawadskii. Flow cytometry proved to bea simple, rapid, and highly accurate method for identifying ploidy levels in Chrysanthemum species.

In this scheme, N non-maximally entangled particle pairs are used as quantum channel to teleport an unknown N-particle entangled GHZ state via entanglement swapping. In order to realize this teleportation, the sender Alice operates Bell-state measurement on particles belonging to herself. Then she informs the results to the receiver Bob through classical communication. According to the results, Bob operates corresponding transformation to reconstruct the initial state. The advantage of this scheme is that it needs only one common unitary matrix for Alice＇s different results, which has a more general meaning. As a special case, teleporting an unknown three-particle entangled GHZ state is proposed.

Endovascular aneurysm repair （EVAR） has been proven to be an effective and safe technique for abdominal or iliac artery aneurysm. However, for aneurysms extending to both iliac bifurcations, routine EVAR will occlude both internal iliac arteries （llAs）, which may increase the risk for pelvic ischemia. New endovascular techniques have been developed to preserve the pelvic perfusion in EVAR for such situation. This article reports an endovascular repair of an aortoiliac aneurysm with an external iliac artery （EIA） to the IIA endograft to preserve the pelvic perfusion. First, an endograft was advanced into the left IIA under the help of an inflated aortic balloon. Coils were deployed to embolize the distal type-1 endoleak from the tunnel around the endograft, and an aortouniiliac endograft and an iliac extension were deployed below the renal arteries extending to the right EIA. Finally, a right-to-left femoro-femoral artery bypass was constructed. Angiography at completion and computed tomography after 6 months demonstrated patency of all grafts and complete exclusion of the aneurysm without any endoleak. Endovascular repair with an EIA-to-IIA endograft to preserve the pelvic inflow is a feasible and effective technique for aortoiliac aneurysms. Coil embolization might be an option to repair the distal type of endoleak. The balloon assisted U-turn technique may help advance the endovascular device over a sharp-angled vessel bifurcation.

西南天山变质俯冲杂岩带的内部结构——来自木扎尔特剖面的启示

作者： Yi-lin xue Kun-ling WU jiang-wei xue Beijing Sport University Library Hainan Normal University

In this paper, The non deterministic bidding procurement decision system is introduced, which is an improved method to solve the bottleneck of deterministic procurement decision system and its disconnection from the procurement bidding process, that makes the deterministic project bidding changed into non-deterministic project bidding, and makes the non-deterministic price decision changed into deterministic price decision, in a word, the deterministic procurement decision can be realized by way of the bidding of uncertain procurement projects, as a result, the status and state of the supply and demand sides in the procurement game will be changed, and the fairness and justice of the whole process of government procurement will be realized, and the corresponding embodiment, case of library purchase database is introduced.

西南天山高压-超高压变质带是世界上少有的经历深俯冲的增生杂岩带,是古天山洋向北俯冲的结果。针对该俯冲杂岩带内部结构的研究目前仍存在争论。本文以木扎尔特地区一条长约4 km的南北向剖面为例,对西南天山高压-超高压变质带的野外特征、矿物学和变质演化研究进行了综述。目前的研究表明,木扎尔特地区存在超高压和高压两类硬柱石榴辉岩,但绝大部分都经历了强烈的退变质和变形改造,被蓝片岩相或绿片岩相矿物组合取代。这些变基性岩在空间上构成北部和南部两个榴辉岩带,二者为构造接触。木扎尔特超高压硬柱石榴辉岩与其围岩经历相似的峰期压力构成西南天山超高压带的西端。与东侧阿克牙孜地区超高压榴辉岩相比,它们在变形特征、岩石组合和变质演化方面表现出一定的独特性,很可能说明深俯冲板片在折返过程中沿构造带走向存在差异变质-变形演化。这些基础研究对全面认识冷俯冲增生杂岩带的变质演化及其俯冲和折返的地球动力学机制具有重要意义。

《冯少墟集》为明代关学重要人物冯从吾的文集,该集在明清两代增补多次,现存八种刻本俱出于已佚的万历四十年本。存世明刻本皆为冯氏在世时付梓,均未收录天启元年后的作品。清刻本中,康熙本内容较完整,讹误较少,是较好的版本;光绪本内容虽为最全,但讹漏较多,且打破了《冯少墟集》原有结构;《四库全书》本多有删改,且未收《冯少墟集》续集部分;《广明儒理学备考》本仅为选集。综合比较,在现存版本中康熙本最佳,后两者文献价值一般,故整理是书正集应以天启本为底本,康熙本为校本,并参校万历四十五年本、云南省图书馆藏本,续集应以康熙本为底本,光绪本为校本。
