肝肾疾病患者血清转铁蛋白和铜蓝蛋白含量的分析

对肝肾疾病进行转铰蛋白(Transferren简称TF)和铜蓝蛋白(Ceruloplasmin简称CP)测定,结果表明:各组肝炎病人的TF均显著低于正常组,且谷丙转氨酶异常和HBsAg阳性者TF含量明显低于正常者,TF可作为判断肝病预后的一个指标。肾炎病人的TF也比正常人低,CP含量各组不一,肝癌患者的CP(52.44±8.73mg％)显著高于正常人(46.75±7.92mg％),乙型肝炎病人和正常组间未见差异.肝豆状核变性患者CP非常显著低于正常人,故检测CP有助于鉴别肝硬化和肝癌,同时对临床诊断肝豆状桉变性提供一项可靠的客观指标.     

Walsh Operational Matrices for Fractional Calculus and Their Application to Distributed Systems

The Walsh operational matrix for performing integration and solving state equations is generalized to fractional calculus for investigating distributed systems. A new set of orthogonal functions is derived from Walsh functions. By using the new functions, the generalized Walsh operational matrices corresponding to √s, √(s²+ 1), e^-s and e^-√s etc. are established. Several distributed parameter problems are solved by the new approach.

新形势下中国企业培育国际竞争力分析

面对经济转型和全球化的影响,提升国际竞争力和参与中国乃至世界市场与行业的整合,已经成为中国企业突破市场、资源和环境约束,实现可持续发展的必然选择。在提升国际竞争力的过程中,中国企业必须克服制度因素、企业因素和互动因素三个方面的限制;必须在中国政府进一步的改革和中国企业战略行为调整的基础上,充分发挥国家特定优势和企业特定优势来培育中国企业的国际竞争力;必须充分将资源高度集中于主业,通过横向和纵向整合做强主业,提升在主业上与国外跨国企业动态互动的能力。     

Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy

Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.     

Understanding divergent domestication traits from the whole-genome sequencing of swamp- and river-buffalo populations

Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.     

基于GOCI影像的杭州PM2.5遥感建模及时空变异分析

地球静止卫星上的GOCI(geostationary ocean color imager)传感器具有较高的时间分辨率,在研究短时间尺度内大气PM2.5浓度时空变化方面具有一定的应用潜力.本文根据GOCI影像的波段特征,利用2011-2013年实测PM2.5浓度、大气气溶胶光学厚度(aerosol optical depth,AOD)与气象因子数据,分别进行了GOCI PM2.5浓度单变量和多变量反演建模研究,并结合2013年12月6日的GOCI AOD数据,实现了单日杭州市PM25浓度遥感反演与时空变异分析.结果表明:在单变量模型中,分季节模型的平均相对误差最高值28.11％比年度模型的平均相对误差34.04％低,分季节模型精度优于年度模型;单变量模型的平均相对误差34.04％比多变量模型的平均相对误差48.96％低,单变量模型精度优于多变量模型;把单变量冬季模型应用于杭州GOCI AOD数据,得出逐时大气PM2.5的空间分布,并计算了PM2.5浓度的变异系数,发现杭州各区县变异系数大都在0.5以下,东部和北部的数值较高,中西部地区的值较低.     

Adaptive fuzzy CMAC-based nonlinear control with dynamic memory architecture

An adaptive fuzzy cerebellar model articulation controller-based (CMAC) nonlinear control with the advantage of architecture learning is proposed. To cope with the tradeoff between the complexity of CMAC architecture and the quality of system convergence, a dynamic architecture learning scheme is introduced, where the associative memory reinforcement and the associative memory reorganization are involved. In the memory reinforcement process, new associative memories will be generated when the memory cells in the current architecture are found insufficient. On the other hand, the inefficient memories will be detected and reorganized in the memory reorganization process. With the proposed approach, the task of fuzzy CMAC architecture determination by preliminary knowledge or trials can be freed when a well-organized and well-parameterized CMAC is represented to achieve desired approximation performance. Thus, with the proposed CMAC, a dynamic control approach is presented. In this paper, according to the adaptive control theory, the fuzzy CMAC (FCMAC) is utilized as the main controller to mimic the ideal computation controller and a supervisory controller is designed to compensate the approximation error. In the FCMAC, all the controller parameters are online tuned based on the Lyapunov stability theorem such that the stability of closed-loop system can be guaranteed. Simulation results and comparisons are presented for verification.     

主控式IT外包——高校信息化实践模式的新思路

国内高校信息化主要采取自主研发和厂商合作方式来完成,按照高校实施策略的不同,大致可分为"自主研发型"和"IT外包型",自主开发具有贴近用户、修改便捷、信息安全相对有保障等优点,但是对IT技能和项目管理能力等要求较高;IT外包具有节约成本、快速提升信息化水平、提升业务管理能力等优点,但容易造成对厂商过度依赖、形成技术黑洞、维护学校权益困难等缺点。在信息化实践中逐步产生融合两者优点又能消除其弊端的实践模式——主控式外包,即高校在自身的技术力量、管理能力基础上,利用IT厂商的成熟技术和人才资源,掌握信息化实施的主导权,参与项目的各个环节建设,从而达到安全性高、可维护性强、项目满意度高等效果。
