1不同围压下岩石中泊松比的各向异性显示文摘由弹性波纵横波速比计算得到的泊松比 ,在利用地震波反演地下结构和物质组成时 ,可以提供比单纯地利用纵波或者横波波速更强的约束 .为了研究不同岩石中泊松比及其各向异性随围压的变化 ,选取 1 9块典型的岩石样品 ,在不同围压下沿相互正交的 3个方向同时测量纵、横波速度 ,并通过计算得到了泊松比及其各向异性 .结果表明 ,在大部分样品中泊松比各向异性与纵波速度各向异性有一定的相关性 ,但在有的样品中泊松比各向异性与纵波速度各向异性没有明显的关系 ,甚至表现出完全相反的变化规律 .由于泊松比也表现出很强的各向异性 ,在排除微裂隙的影响后有的仍可以达到 30 %以上 ,在利用实际地震波传播数据通过泊松比反演地下物质结构时必须考虑其各向异性的影响 .刘斌 席道瑛 葛宁洁 王宝善 H.

5Mechanism of interaction between electromagnetic fields and living organisms显示文摘Based on nonlinear phenomena of biophoton emission observed in the past, an interference model concerning with the mechanism of interaction between living organisms and electromagnetic fields was raised. Caused by biological nonlinearly polarizable double layer, destructive interference of incoming and reflected waves establishes in the outside. As a consequence, in the inside constructive interference takes place at the same time. The interference patterns may play an important role in biological self organization and in biological functions. We investigate the boundary conditions necessary for explaining these non-linear optical effects in terms of the phase conjugation. It turns out that there are solutions of the Maxwell equations which satisfy destructive interference of biophotons in agreement with the experimental results. Necessary provisions are nonlinearly polarizable optically active double layers of distances which are small compared to the wavelength of light. In addition, they have to beFritz-Albert Popp 张锦珠 2000Science China(Life Sciences)2000,43,5:4

7Quality of life after liver transplantation:State of the art显示文摘Quality of life(QoL) after deceased donor liver transplantation is increasingly recognized as a major outcome parameter. We reviewed recent publications in this rapidly evolving field in order to summarize recent achievements in the field and to define opportunities and perspectives for research and improvement of patient care. QoL does improve after liver transplantation according to a typical pattern. During the first year, there is a significant improvement in QoL. After one year, the improvement does stabilise and tends to decline slightly. In addition to the physical condition, different psychological parameters(such as depression, anxiety, sexual function) and sociodemographic elements(professional state, sex, marital state) seem to impact QoL. Opportunities for further research are the use of dedicated questionnaires and identification of influencing factors for QoL.Louis Onghena Wouter Develtere Carine Poppe Anja Geerts Roberto Troisi Aude Vanlander Frederik Berrevoet Xavier Rogiers Hans Van Vlierberghe Xavier Verhelst 2016World Journal of Hepatology2016,8,18:3
8Superior labral anterior posterior lesions of the shoulder:Current diagnostic and therapeutic standards显示文摘Surgical treatment of superior labral anterior posterior(SLAP) lesion becomes more and more frequent which is the consequence of evolving progress in both,imaging and surgical technique as well as implants.The first classification of SLAP lesions was described in 1990, a subdivision in four types existed. The rising comprehension of pathology and pathophysiology in SLAP lesions contributed to increase the types in SLAP classification to ten. Concerning the causative mechanism of SLAP lesions, acute trauma has to be differed from chronic degeneration. Overhead athletes tend to develop a glenohumeral internal rotation deficit which forms the basis for two controversial discussed potential mechanisms of pathophysiology in SLAP lesions: Internal impingement and peel-back mechanism. Clinical examination often remains unspecific whereas soft tissue imaging such as direct or indirect magnetic resonance arthrography has technically improved and is regarded to be indispensable in detection of SLAP lesions. Concomitant pathologies as Bankart lesions, rotator cuff tears or perilabral cysts should be taken into consideration when planning a personalized therapeutic strategy. In addition, normal variants such as sublabral recess, sublabral hole, Buford complex and other less common variants have to be distinguished. The most frequent SLAP type Ⅱ needs a sophisticated approach when surgical teatment comes into consideration. While SLAP repair is considered to be the standard operative option, overhead athletes benefit from a biceps tenodesis because improved patient-reported satisfaction and higher rate of return to pre-injury level of sports has been reported.Dominik Popp Volker Sch?ffl 2015World Journal of Orthopedics2015,6,9:3
9利用光子发射研究海洋甲藻间的细胞通讯显示文摘细胞通讯,或称细胞信息传递的研究,已成为分子生物学、细胞生物学、细胞生物物理学研究的热点,引起了许多生物学家乃至物理学家们的兴趣,因为人们认识到对许多重要的生命现象,例如生长发育、细胞分化、肿瘤发生、神经信息加工等的解释,归根到底还要在对细胞通讯的研究中得到解答.近年来,人们对细胞的化学信号传递的研究取得了一些新进展,但是长距离的细胞间的通讯在理论上仍要依赖于物理方式.张锦珠 于文斗 Fritz-Albert Popp 1994科学通报1994,39,20:3

13Biophoton Emission as a Potential Measure of Organizational Order显示文摘Beginning with the quantum theory of biophoton emission,a c-number equation character-izing the excited-state dynamics of a complex system of collective biomolecules in interaction with both the'pumping'field and the biophoton field is presented,and then the order-growth process of the system interms of both determinism and statistics is investigated.A general expression describing the order-growthdynamics of biological systems,which reduces in a limiting case to the well-known growth curve,is obtained.Then a Fokker-Planck equation for probability density function of an order parameter q of the systemhas been established.The solution predicts that the system under consideration can evolute from an arbitraryinitial state to a pure state characterized by the steady-state order parameter q1.Furthermore,the evolutionof the maximum entropy of the system is discussed,which shows that the system investigated is to keep anabsolute maximum of entropy,and at the same time,to minimize its entropy value by reducing the uncertain-ty of the order parameter.Finally,some agreements of the theoretical results with the corresponding experi-mental observations of order-growth process demonstrated by the biophoton emission are shown,which indi-cates that biophoton emission may serve as a potential measure of the organizational order.顾樵 Popp Fritz-Albert 1994Science China Chemistry1994,37,9:2
