Detecting myocardial ischemia with 2-D CVIB imaging method--an in vivo animal experiment study

A 2-D cyclic variation of integrated backscatter (CVIB) imaging method was established for detecting myocardial ischemia. To demonstrate the feasibility and validity of this method, animal experiments were conducted. Acute myocardial ischemia was induced by occluding left anterior descending coronary artery in 10 anesthetized open-chest dogs. While scanning the normal hearts and the ischemic hearts with a B scanner, digital radiofrequency data were acquired by a real-time acquisition system in synchronism. The offline analysis to the radio-frequency signal with the 2-D CVIB imaging method was performed to verify the consistency between the imaging result and the design of the experiment. In addition, 4 dogs in experiment were treated with the heart pacemaker in order to investigate the influence of changing in heart rate on the detection of ischemic myocardium with the proposed method. The experimental result showed that the 2-D CVIB imaging method succeeded in detecting the ischemic myocardium and is a new non-invasive way for the cardiologists to both quantitatively and visually evaluate the contractile performance of the myocardium.

基于改进等分节点法的启发式布局算法

针对集成电路标准单元模式的布局问题，提出了一个全新的基于改进等分节点法的启发式标准单元布局算法(TETP)，该算法在优化布局过程中采用改进的等分节点法寻找单元目标位置，同时结合局部寻优的启发式算法，对MCNC(Microelectronics Centre of North-Carolina)标准单元测试电路进行实验。结果表明，与布局工具Timber Wolf7．0和FengShui相比，电路布局的总线长度分别平均减少了16％和17％。     

采用自举技术的不完全绝热电路

为了大规模集成电路的低能耗应用,提出了一种不完全绝热电路——自举能量回收逻辑电路(bootstrapenergyrecoverylogic,BERL)。该电路采用二相无交叠功率时钟。由于采用自举技术,使负载的冲放电过程不会产生非绝热损失,并且输出开关的导通电阻变小,使绝热损失降低。为了比较BERL电路与静态CMOS电路及PAL-2n绝热电路的能耗,设计了反相器链电路。Hspice软件仿真结果表明,BERL电路的工作频率可以超过400MHz。在10～100MHz下,BERL能耗只有静态CMOS电路的25%～33%。相对于PAL-2n电路,BERL也有较低的能耗。在200MHz下,BERL能耗只有PAL-2n的50%。负载越重,BERL电路的低能耗优势越明显。

Impoverishment of Soil Nutrients in Gully Erosion Areas in Yuanmou Basin

The impoverishment of soil nutrients of nine gully head areas in Yuanmou Basin is assessed through an integrated evaluation method established on the basis of Fuzzy mathematics and multivariate mathematical theory. Results show that soil erosion of gully erosion area in Yuanmou basin has resulted in severe impoverishment of soil nutrients. All gully head areas are at high leves of impoverishment except for one at middle. By probing into and analyzing the mechanism of impoverishment of soil nutrients, we find that soil erosion has led to impoverishment of soil nutrients in a way of compacting soil, heightening position of obstacle horizon, and reducing the content of organic matter, as well as the direct loss of nutrient elements. Finally, this paper points out that soil and water conservation arming at the prevention of soil erosion is the most effective way against impoverishment of soil nutrients in Yuanmou basin.
