This paper presents a low power multi-channel chirp-UWB (C-UWB) transmitter for short range communication systems. The C-UWB transmitter generates a wideband FM signal with a steep spectral roll-off, while enabling a duty-cycled operation. To achieve an optimum duty-cycle control, burst-mode transmission and steep digital gradient generation techniques are employed. A 5-to-9GHz C-UWB transmitter is implemented in 65nm CMOS for multi-channel operation with a channel bandwidth of 500MHz. The transmitter achieves 1Mb/s data rate, consuming 0.5mW from a 1V supply.

Studies using the European rabbit Oryctolagus cuniculus contributed to elucidating numerous fundamental aspects of antibody structure and diversification mechanisms and continue to be valuable for the development and testing of therapeutic humanized polyclonal and monoclonal antibodies. Additionally, during the last two decades, the use of the European rabbit as an animal model has been increasingly extended to many human diseases. This review documents the continuing wide utility of the rabbit as a reliable disease model for development of therapeutics and vaccines and studies of the cellular and molecular mechanisms underlying many human diseases. Examples include syphilis, tuberculosis, HIV-AIDS, acute hepatic failure and diseases caused by noroviruses, ocular herpes, and papillomaviruses. The use of rabbits for vaccine development studies, which began with Louis Pasteur's rabies vaccine in 1881, continues today with targets that include the potentially blinding HSV-1 virus infection and HIV-AIDS. Additionally, two highly fatal viral diseases, rabbit hemorrhagic disease and myxomatosis, affect the European rabbit and provide unique models to understand co-evolution between a vertebrate host and viral pathogens.

目的:探索μ阿片受体(MOR)在大鼠结肠肠肌丛的分布及化学神经解剖学特性。方法:取大鼠结肠右曲和左曲之间肠管行全层铺片,剥离粘膜层、粘膜下层和环形肌层,保留纵行肌层。运用免疫荧光组织化学双重标记技术染色,共聚焦显微镜下观察MOR在大鼠结肠肠肌丛的分布及与一氧化氮合酶(NOS)、肠血管活血肽(VIP)、P物质(SP)或降钙素基因相关蛋白(CGRP)等在肠神经细胞的共存关系。结果:免疫荧光组织化学染色显示:在大鼠结肠肠肌层,MOR阳性细胞聚集形成神经节,其阳性突起穿行于神经节之间形成网格状神经丛。在肠肌丛神经细胞内,可见MOR分别与NOS、VIP、SP、CGRP共存。MOR阳性神经纤维和终末分布于NOS阳性神经细胞周围,也可见部分NOS、VIP阳性神经纤维和终末分布于MOR阳性神经细胞表面。有大量SP和CGRP阳性神经纤维穿行于MOR阳性神经细胞之间并包绕于MOR阳性神经细胞的胞体周围。结论:在结肠的肠肌丛,MOR与抑制性和感觉性神经递质在肠神经细胞有共存,且相互之间有纤维联系,推测MOR可能介导了阿片类调节肠神经细胞内抑制性神经递质的释放,并可能对肠感觉信息的传递有调节作用。

A modified image matching algorithm based on robust Hausdorff distance

引用

High Technology Letters 2014年第1期20卷 29-33页

作者：吴强 Wu Xuefeng Li xuwen jia Kebin College of Electronic Information and Control Engineering Beijing University of Technology College of Life Science and Bio-engineering Beijing University of Technology

Hausdorff distance measure is one of the widely adopted feature-based image matching algo- rithms due to its simplicity and accuracy. However, it is considered that its robustness still needs to be improved. In this paper, various forms of original and improved Hausdorff distance （HD） and their limitations are studied. Focusing on robust Hausdorff distance （ RHD）, an improved RHD with an adaptive outlier point threshold selection method is proposed. Furthermore, another new form of the Hausdorff distance which possesses the merits of RHD and M-HD is prsented. Finally, a recur- sire algorithm is introduced to accelerate the image matching speed of Hausdorff algorithms. Exten- sive simulation and experiment results are presented to validate the feasibility of the proposed Haus- dorff distance algorithm.
