The optimal power distribution in cooperative communication relay system

In order to optimize power utilization of relay nodes in cooperative communication,a power allocation algorithm with objective function to maximize system capacity is proposed.Based on the convex optimization theory,an ellipsoid algorithm is used to solve this problem,which could simplify the subgradient choosing steps and improve convergence stability,so that an optimized power allocation algorithm is presented.Theoretical analysis and simulation results show that the algorithm can effectively distribute the power of each node with lower complexity,and ensure the transmission capability of relay nodes in cooperative communication.     

有限密度下QGP相变的演化图象

在流体力学模型的基础上，利用袋模型分析了在零温有限密度极限下从夸克胶子等离子体（TGP）到强子气体（HG）的一级相变的演化图象。引入QGP所占系统体积的份额描述在有一级相变发生时QGP的强子化剩余率。结果表明强子化剩余率随固有时的增加从1（完全QGP相）逐渐减小到0（完全强子相）。给出了在QGP相、QGP和强子共存区以及强子气体相的能量密度和化学势随固有时的演化关系。

硫胺缺乏所致血液透析相关性脑病的临床分析

分析硫胺（维生素B1）缺乏所致血液透析相关性脑病的临床特征，并探讨其早期诊断与治疗方法。方法：对10例临床诊断为硫胺缺乏所致血液透析相关性脑病患者的临床表现、治疗及疗效等进行临床分析。结果：本组患者临床表现呈多样化，包括舞蹈病、快速进展性痴呆、肌阵挛、抽搐、意识模糊、嗜睡和昏迷等。10例中7例经肌肉注射维生素B1后病情缓解，3例死亡患者其维生素B1治疗均开始于脑病表现出现1周以后。所有病例均为伴有严重消化道症状的初次接受血透治疗的患者。结论：血液透析病人出现难以解释的中枢神经系统表现时，应高度重视硫胺缺乏所致血液透析相关性脑病的发生，及时补充维生素B1及营养支持治疗可望缓解病情，否则可致患者可死亡。

坚硬岩层巷道掘进合理掏槽方法的研究与应用

针对坚硬岩层巷道掘进中存在爆破效率较低的问题,在会理县兴隆矿业矿山坚硬岩层巷道开挖中进行爆破试验,对混合掏槽、单螺旋形掏槽和正矩形掏槽三种掏槽方式进行分析研究,得到各种不同掏槽形式的爆破试验效果,选取最为合理的掏槽方法和爆破参数.试验表明,采用单螺旋形掏槽的布孔方式,平均循环进尺达到1.7 m,炮孔利用率大于85%,提高了巷道的掘进速度和成巷质量.试验成果可供其他类似工程参考.

Reconstructing the food structure of ancient coastal inhabitants from Beiqian village: Stable isotopic analysis of fossil human bone

The Beiqian site located in Jimo city,Qingdao,a few kilometers from the modern coastline was excavated in 2007,2009 and 2011.A large number of human bones from the early Dawenkou period were unearthed.Through C and N stable isotopic analysis,the food structure of the "Beiqian" ancestors was reconstructed and the influence of terrestrial and marine resources on their lifestyle was discussed.Based on the δ13C and δ15N stable isotopic values of human bone collagen,the analytical results obtained through a ternary mixed model reveal that the food sources of the Beiqian ancestors included about 44.1% marine species(probably shellfish and fish),34.1% C4 plants(possibly millet),and 21.8% land animals.These results indicate that they lived mainly from fishing and farming,supplemented by hunting or poultry raising.Compared with other sites in the same period,the stable isotope results show that 5000-6000 years ago,the lifestyles of ancestors in the Yangtze River basin,Yellow River basin,Northern coastal area and inland area were very different.The ancestors from the Yangtze River basin focused on rice farming and fishing,whereas the ancestors in the Yellow River basin farmed millet and raised animals.Those in coastal areas relied mostly on farming and marine fishing.     

FENG Guo-dong, et al

Aim To investigate a new method for synthesis of an Immobilized-Metal Affinity Chromatography(IMAC) adsorbent with superparamagnetism(Fe3O4/SiO2-GPTMS-Asp-Co).Method The magnetic microspheres were synthesized in situ modification and the transmission electron microscope,field emission scanning electron microscopy,X-ray diffractometer,energy spectrometer and vibrating sample magnetometer were used to characterize the appearance,particle size distribution,phase composition,chemical constituents and magnetic properties of silica magnetic microspheres(MMS).Results The silica MMS prepared by reverse microemulsions exhibit a superior core-shell structure.The size distribution of the microspheres varies from between 100 nm to 200 nm and the main phase of microspheres is amorphous SiO2 and spinel Fe3O4.The microspheres retain superparamagnetism and can be used as biomaterials.Conclusion The result indicates that the IMAC adsorbent we prepared has outstanding advantages in the separation of the natural products proteins from the crude bacterial lysate,such as simple operation,high selectivity and capacity.
