类风湿关节炎(RA)是一种以全身多发关节炎为主要表现的慢性系统性炎症性疾病,以双手和腕关节等小关节受累为主。RA的病理表现为关节滑膜的慢性炎症、血管翳形成,并出现关节的软骨和骨破坏,最终导致关节畸形和功能丧失。RA为反复发作性疾... 详细信息

类风湿关节炎(RA)是一种以全身多发关节炎为主要表现的慢性系统性炎症性疾病,以双手和腕关节等小关节受累为主。RA的病理表现为关节滑膜的慢性炎症、血管翳形成,并出现关节的软骨和骨破坏,最终导致关节畸形和功能丧失。RA为反复发作性疾病,致残率高,目前尚无有效根治方法,而中医药在减轻RA炎症反应方面效果显著。因此,深入研究中医药在RA中的应用及炎症反应机制,可以为RA的治疗提供新思路。

As a new software paradigm evolved by the Internet, Internetware brings many challenges for the traditional software development methods and techniques. Though architecture-based component composition （ABC） approach is originated in the traditional software paradigm, it supports the engineering of Internetware effectively due to its philosophy, rationales and mechanisms. ABC has three major contributions to the en- gineering of Internetware in detail. First, the feature oriented domain modeling method can structure the ＂disordered＂＂software entities＂ to ＂ordered Internetware＂ bottom-up in the problem space. Second, the architecture centric design and analysis method can support the development of self-adaptive Internetware. Third, the component operating platform is a reflective and self-adaptive middleware that not only provides Internetware with a powerful and flexible runtime infrastructure but also enables the self-adaptation of the structure and individual entities of Internetware.

A novel low-swing interface circuit for high-speed on-chip asynchronous interconnection is proposed in this paper. It takes a differential level-triggered latch to recover digital signal with ultra low-swing voltage less than 50 mV, and the driver part of the interface circuit is optimized for low power using the driver-array method, With a capacity to work up to 500 MHz, the proposed circuit, which is simulated and fabricated using SMIC 0.18-pm 1.8-V digital CMOS technology, consumes less power than previously reported designs.

This paper investigates the problem of almanac affecting the signal acquisition time with two constraints: different age of data and multi-sets of almanac. The contributions made in this paper include: 1) the exploiting of signal acquisition concept to extend well-known almanac function of predicting visible satellite and initializing signal acquisition to minimizing the signal acquisition time; 2) a model based on code phase and Doppler frequency to reflect the impact of multi-sets of almanac on the signal acquisition time; 3) the evaluation of the existing GPS almanac with different broadcast strategy. The theoretical analyses and simulations conducted on three sets of almanac show that the model proposed in this paper is general and efficient for almanac design and application.
