Molecular topology is one of the important topics to study and understand the relationship between molecular structure and properties [1]. Particularly, two-dimensional (2D) materials with extremely high surface area and ultra-thin morphology have attracted considerable attention due to their unexpected properties in materials and chemistry [2,3].

Paroxysmal nocturnal hemoglobinuria （PNH） is a consequence of nonmalignant clonal expansion of one or several hematopoietic stem cells that have acquired a somatic mutation of phosphatedalinositol glycae-class A （PIGA） gene leading to deficient glycosyl phosphatidylinositol （GPI） synthesis. The pathophysiology of PNH is an abnormality in the glycolipid-anchored proteins of the membranes of blood cells. The absence of complement control proteins, including decay accelerating factor （DAF, CD55） and membrane inhibitor of reactive lysis （MIRL, CD59）, results in intravascular lysis of the abnormal cells. Patients with PNH manifest not only clinical and laboratory signs of chronic hemolytic anemia, but also formation of cytopenia and venous thromboses.

系统研究Mg-5Sn合金在不同处理条件下析出相取向的演变及其对合金热导率的影响。结果表明,在先时效后孪生处理的合金(样品AT)中,基面析出相被调整为柱面析出相,并且板条状析出相发生3.7°的刚性转动以协调孪晶剪切;而样品AT中厚度较大的六边形析出相则只发生了0.2°的刚性转动,这是由于堆垛层错能够释放部分析出相/孪晶界的应变。此外,析出相的取向显著影响合金的热导率。当热导率测试方向平行于挤压方向时,与平行于挤压方向的柱面析出相相比,垂直于挤压方向的基面析出相更有利于合金热导率的提高。基面有析出相的TA(先孪生后时效处理)样品具有最佳的热导率(137.81 W/(m·K))。

Non-stoiehiometry effect on the extreme magnetoresistanee is systematically investigated for the Weyl semimetal WTe2. Magnetoresistance and Hall resistivity are measured for the as-grown samples with a slight difference in Te vacancies and the annealed samples with increased Te vacancies. The fits to a two-band model show that the magnetoresistanee is strongly dependent on the residual resistivity ratio （i.e., the degree of non-stoichiometry）, which is eventually understood in terms of electron doping that not only breaks the balance between electron-type and hole-type carrier densities, but also reduces the average carrier mobility. Thus the compensation effect and ultrahigh mobility are probably the main driving force of the extreme magnetoresistance in WTe2.

Background Different kinds of minimally invasive surgery （MIS） procedures have now been used in total knee arthroplasty （TKA）. Compared with traditional TKA procedure with a long skin incision, clinical studies showed MIS procedures had some advantages. Quadriceps sparing （QS） procedures are the most minimally invasive MIS procedure until now. This study was aimed to find the insertion types for Chinese patients＇ vastus medialis and if the QS procedure had some advantages in patients＇ early recovery. Methods Between February 2006 and May 2007, 120 consecutive patients underwent unilateral primary TKA under general anesthesia, among whom 14 patients were lost to follow-up, the remaining 106 cases were enrolled in this study. Among the 106 cases there were 85 right knees, 21 left knees （15 men and 91 women, with a mean age of 65.1±7.4 years）; osteoarthritis in 97 patients （91.5%） and rheumatoid arthritis in 9 patients （8.5%）. MIS TKA was performed in 49 cases （MIS TKA group）, while MIS-QS TKA in 57 cases （MIS-QS TKA group）. During the operation, the type Ⅰ, Ⅱ and Ⅲ insertions of the vastus medialis for all patients were recorded. Each knee was rated post-operatively according to the Hospital of Special Surgery （HSS） scoring system. Clinical follow-up was undertaken at 1 week, 2, 6, 12 and 24 weeks. Operating time and complications were recorded. Results There was no statistically significant difference between the two groups for gender distribution, age, left or right knee incidence, pre-operative diagnosis, incidence of varus or valgus deformity. Of the 106 cases there was 1 （0.9%） case with a type Ⅰ insertion of the vastus medialis, 4 （3.8%） cases with type Ⅱ insertions, 101 （95.3%） cases with type Ⅲ insertions. The HSS scoring was significantly different between the MIS-QS TKA group and MIS TKA group within the first two weeks post operation. From 2 weeks later to 24 weeks, no significant difference was found. The average operating time was （53.3±12.4） minutes in t

研究了供应商和制造商产出随机且零售商面临随机需求的三级供应链协调模型,决策变量为供应商的原材料投入量、制造商的订购量和零售商的订购量。分析了集中决策下供应链协调基准的唯一性,论证了回购契约及其与产出风险分担组合契约的协调性。研究结果表明,对于产出和需求不确定的三级供应链,仅考虑在制造商和零售商之间采用回购契约可改善供应链绩效,但并不能实现供应链的全局最优化,而从风险分担的角度设计的回购和产出风险分担组合契约不仅能有效的协调供应链,且在一定条件下,各供应链成员的利润还能获得帕累托改进。通过算例验证了以上结论的正确性,并分析了回购价格对订购量、原材料投入量和利润的影响,以及各供应链成员对契约的偏好。
