Under partial trade credit,suppliers usually require retailers to pay a fraction of the purchase cost immediately when ordering and the remaining payment is deferred at the end of the sales *** a supply chain consisting of a risk-neutral supplier and multiple loss-averse retailers,we develop models under partial trade *** analyze the optimal decisions of a supplier and retailers under decentralized *** study shows that there is a unique Nash equilibrium among the retailers,and the optimal total order quantity of retailers increases as the delayed payment ratio increases and as the degree of retailers'competition increases,but decreases with an increase in the loss *** studies are conducted to demonstrate the solution procedures and the effects of the parameters on decisions and profits.

BACKGROUND： Capillaries are the only blood supply for optic nerves, which makes the system more vulnerable to impaired blood circulation. OBJECTIVE： To observe the ultrastructural changes in the optic nerves and capillaries in rabbits following intracanalicular segment injury to the optic nerve. DESIGN, TIME AND SETTING： Comparative, observational, pathological morphology was performed at the Department of Anatomy, Weifang Medical College from September to November 2007. MATERIALS： Models of intracanalicular segment injury to the optic nerve were induced in the right eye of thirty healthy, adult rabbits by a free-falling metal cylinder. The H-7500 transmission electron microscope was provided by Hitachi, Japan. METHODS： All rabbits were randomly assigned into experimental （n = 25） and control （n = 5） groups. Optic nerve specimens were obtained from the experimental group at 0.5, 6, 12, 48, and 96 hours, respectively, following injury. Ultrastructural changes to the optic nerves and their capillaries were observed by electron microscopy. Optic nerve injury was not established in the control group, but optic nerve specimens were collected similarly to the experimental group. MAIN OUTCOME MEASURES： Ultrastructural changes in the injured optic nerves and their capillaries. RESULTS： Thirty rabbits were included in the final analysis. In the control group, cross-sections of the optic nerves exhibited varied thicknesses with regularly arranged fibers. The axons appeared to be smooth with condensed myelin sheaths and oval mitochondria. The microtubules and microfilaments were clearly seen. The lumens of the capillaries were regular with densely arranged endothelial cells and visible mitochondria. In the experimental group, 30 minutes after injury to the optic nerves, swollen axons, sparse myelin sheath, disordered microtubules and microfilaments, swollen mitochondria, and a decreased number of pinocytosis vesicles and microfilaments in endothelial cells of the capillaries w

Eucommia ulmoides, also called hardy rubber tree, is an economically important tree; however, the lack of its genome sequence restricts the fundamental biological research and applied studies of this plant species. Here, we present a high-quality assembly of its ~l.2-Gb genome （scaffold N50 = 1.88 Mb） with at least 26 723 predicted genes for E. ulmoides, the first sequenced genome of the order Garryales, which was obtained using an integrated strategy combining Illumina sequencing, PacBio sequencing, and BioNano mapping. As a sister taxon to lamiids and campanulids, E. ulmoides underwent an ancient genome triplication shared by core eudicots but no further whole-genome duplication in the last ~125 million years. E. ulmoides exhibits high expression levels and/or gene number expansion for multiple genes involved in stress responses and the biosynthesis of secondary metabolites, which may account for its considerable environmental adaptability. In contrast to the rubber tree （Hevea brasiliensis）, which produces cis-polyisoprene, E. ulmoides has evolved to synthe- size long-chain trans-polyisoprene via farnesyl diphosphate synthases （FPSs）. Moreover, FPS and rub- ber elongation factor/small rubber particle protein gene families were expanded independently from the H. brasiliensis lineage. These results provide new insights into the biology of E. ulmoides and the origin of polyisoprene biosynthesis.

Lau效应是非相干光照明下双光栅干涉形成的光学自成像现象。本文从描述光场传输的波方程出发,基于空间-时间对偶性,建立了时域光学系统脉冲响应函数与ABCD矩阵之间关系,在此基础上设计基于时域非相干光源光场强度关联的二阶Lau成像方案,最后得到描述二阶时域Lau效应的强度涨落关联表达式和周期性光脉冲的再现与介质的群延迟色散(GDD)参量之间的关系,并分析再现的周期性光脉冲的分布规律。结果一方面表明周期性时域脉冲的非局域叠加再现源于关联光脉冲之间的联合色散,另一方面表明当两个时域光栅之间色散介质的群延迟色散参量等于Talbot群延迟色散参量的整数倍时,可获得周期性光脉冲成像。当两个时域光栅之间色散介质的群延迟色散参量等于二分之一Talbot群延迟色散参量的奇数倍时,可实现周期性光脉冲的重现但有半个周期的平移。该结果有助于促进光场强度关联在时域光学中的应用特别是周期性光脉冲在色散介质中的遥感传输。
