Four cDNA clones homologous with a murine prostaglandin E2 receptor have been isolated from a rabbit kidney cortex cDNA library. These cDNAs encode related proteins that differ only in their COOH-terminal sequences. Southern blot analysis of rabbit genomic DNA indicates that these receptor cDNAs represent alternatively spliced variants derived from a single(More)
A two-stage 3.1to 10.6-GHz ultrawideband CMOS low-noise amplifier (LNA) is presented. In our design, a parallel resistance–capacitance shunt feedback with a source inductance is proposed to obtain broadband input matching and to reduce the noise level effectively; furthermore, a parallel inductance–capacitance network at drain is drawn to further suppress(More)
This paper presents the methodology of implementations and performance measurements of our mobile ad-hoc network (MANET) platforms. The work is prompted by the lack of published results concerning the issues associated with the implementation of MANET facilities on actual wireless networks, as opposed to results of simulation experiments. Our MANET is(More)
Field tests of the transmission performance of the ATSC DTV system have been conducted in Taiwan. The test results as well as comparisons against the NTSC system performance are reported and analyzed. From the measured results the reception characteristics of the DTV can be deduced and can provide guidelines for television stations to design transmission(More)
Large-scale video surveillance systems typically deploy many video cameras over a wide area and display video streams on separate screens. Operators of this kind of systems have difficulties perceiving the whole pictures of intermixed views and are prone to losing track of targets. This paper presents a surveillance system which integrates videos from(More)
