信用担保的两阶段定价模型

随着金融市场的日渐完善,信用担保的使用日趋频繁。目前对担保的定价是在单阶段清偿的前提下,采用经验定价和单阶段期权定价两种方法。注意到在担保中存在很多展期的情况。据此,提出了两阶段担保模型,并给出其理论定价及计算实例。     

Experimental Study on the Mechanical Properties of Novel Plate-knitted Composite Tracheal Stents

A new knitted composite artificial tracheal stent made of polyglactin(PGLA) and polypropylene (PP) filaments for reinforcement and regeneration of human trachea has been developed by plated-knitting technique on a small-diameter circular knitting machine. Both tensile and compressive tests were carried out to determine the Young's modulus and the critical pressure corresponding to crushing of the stent. The experimental results confirmed that the new type of knitted composite artificial stent is mechanically feasible.     

Study on the Medical Image Distributed Dynamic Processing Method

To meet the challenge of implementing rapidly advanced, time-consuming medical image processing algorithms, it is necessary to develop a medical image processing technology to process a 2D or 3D medical image dynamically on the web. But in a premier system, only static image processing can be provided with the limitation of web technology. The development of Java and CORBA (common object request broker architecture) overcomes the shortcoming of the web static application and makes the dynamic processing of medical images on the web available. To develop an open solution of distributed computing, we integrate the Java, and web with the CORBA and present a web-based medical image dynamic processing methed, which adopts Java technology as the language to program application and components of the web and utilies the CORBA architecture to cope with heterogeneous property of a complex distributed system. The method also provides a platform-independent, transparent processing architecture to implement the adva

Meteorotropy and medical-meteorological forecasts

The meteorotropic reaction of the human organism is a function of different factors, such as the type and intensity of the effects of the physical environment as well as individual conditions like adaptive capacity and state of health. Many medical-meteorological studies show causal correlations between conditions in the lower atmosphere and reactions of the human organism, but also combined or synergistic effects of different weather situations, which can only be proved stochastically. These effects are described and the methodology of the investigations, as well as the results, critically discussed. Furthermore, application of the results in the areas of medical-meteorological consultation, with the goal of improving living conditions, is considered.     

The consequences of the discovery by W. C. Röntgen for present-day medical physics and radiation protection

When the German physicist W. C. Röntgen discovered X-rays, which were named after him, he introduced a new development in medicine and biology: together with the discoveries of A. H. Becquerel and M. Curie, radiology with its diagnostic and therapeutic methods was made possible. The medical physicist has an important task to fulfill in modern radiotherapy, nuclear medicine and radiodiagnostics. The longtime interdisciplinary collaboration has won the international recognition of medical physics as a scientific discipline, a health care profession and a university subject. Several incidents, including contemporary ones, show that the efforts made towards radiation protection must remain an important domain of the specialist.
