Yangbajain Cosmic Ray Observatory——The world＇s largest experimental base on high elevation

Cosmic rays are flows of high-energy particles coming from the deep of the universe as material samples voluntarily making their way to the Earth from an extra-terrestrial origin. They are involved with some key, unsolved and long-standing puzzles on the cosmic history, evolution of celestial bodies,     

The impact of business models on new - high - tech firms＇ -- Improvement research on Zott model

在互联网时代,随着数字技术的不断发展和市场全球化的加速普及,商业模式对企业经营绩效的影响日益显现,尤其是它在高新技术商业化进程中所具有的价值获取功能,成为影响高新技术企业发展轨迹的重要因素,然而该因素产生作用的机制和条件迄今尚未明确。本文以Zott模型（2008）为基础,将商业模式和竞争战略因素纳入同一模型中,构建了一个整合商业模式与竞争战略的匹配模型。研究表明,在高新技术企业样本分析中,二者的匹配性与盈利性业绩指标呈显著性线性正相关关系,与成长性业绩指标则呈非显著性相关关系。据此扩展了Henry Chesbrouch＆Richard S.Rosebloom（2002）的研究结论,为进一步研究提供了新的依据和方向。

The Max Planck Institute for Biological Cybernetics and Me——True Cooperation Based on True Friendship

I present a series of anecdotes illustrating the friendship and cooperation I have experienced with German scientists. As the sun's rays can be refracted in a tiny drop of water while a whole organism can be cloned from a single somatic cell, my own experiences depict the fruitful past, an encouraging present and a promising future for the flourishing long-term cooperation between the Chinese Academy of Sciences (CAS) and the Max Planck Society (MRS).     

The triad-iodine deficiency,hyperlipidaemia, high coronary risk— in a ‘maternal-neonate’ population of rural Africa

In order to see the pattern of changes in differential serum lipid and lipoprotein fractions as a risk marker of coronary complication in paired ‘maternal—neonate’ blood samples in an iodine deficient zone, 26 pregnant women and their corresponding new born infants at term delivery from the iodine deficient Bassa region of Plateau state, Nigeria were assessed and the results were compared with those seen in a similar 44 group of women and their newborns assessed in non lodine deficient region of Jos. The serum thyroid function and lipid and lipoprotein profiles were determined by ‘ELISA’ and ‘enzymatic’ methods respectively. Urinary iodide excretion level was also measured in 14 pregnant women in Bassa, 23 pregnant women in Jos and 16 non pregnant control from Jos. Results indicate that the pregnant women assessed in Bassa were iodine deficient (P<0.01) and their thyroid status was strikingly reduced as reflected by a drop in serum level of T4/TBG ratio (P<0.01) and a rise in TSH (P<0.005) in comparison to that seen in Jos. There was marked hypertriglyceridaemia and total hypercholesterolaemia (P<0.005), with differential significant rise in LDL cholestotol fraction (P<0.005) in the women assessed in Bassa as compared to Jos. The HDL cholesterol however dropped less significantly in the group (P<0.05) with a concurrent marked rise (P<0.001) in the serum ratio of LDL cholesterol/HDL cholesterol, total cholesterol/HDL cholesterol and triglycerides/HDL cholesterol in the lodine deficient group. A similar pattern of changes were seen in the corresponding neonates in the Bassa group as compared to Jos group. It is concluded that the pregnant women and their newborn offsprings living in a longstanding environmental iodine deficiency run a higher risk of developing coronary complications than those living in non endemic region. It is striking that such newborns surrounded by a continued state of lodine deficient may at a later adult-period of life develop marked risk of coronary complication and other features of hyperlipidaemias associated with varying thyroid insufficiency and accompanied iodine deficiency disorders. Prophylaxis measures as intervention has been highlighted.     

The World's Most Powerful Laser Sheds Light on the GPCR-arrestin Signaling Pathway—— A major breakthrough in structure determination of drug target based on an innovative approach

<正>The structure of Rhodopsin-arrestin complex,which plays a critical role in light perception and visual generation,had long bewildered scientists due to the extremely tiny size of its crystals.Recently an international team led by Prof.H.Eric Xu from the Shanghai Institute of Materia Medica(SIMM),CAS managed to reveal its high-resolution 3D structure at the atomic resolution,using X-ray freeelectron laser(XFEL),the brightest in the world.
