SC1, an integral membrane glycoprotein of 100 kd, is uniquely and transiently expressed on spinal cord motoneurons early in development and appears in peripheral neurons and several other tissues during development. SC1 has been purified by immunoaffinity techniques, and SC1 cDNA clones have been obtained by screening an E4 chick embryo phage expression(More)
To meet the rapidly increasing demand for mobile data traffic, centralized-radio-access-network (C-RAN) has been attracting attention because C-RAN architecture is expected to enable operators to decrease the implementation cost of mobile access networks. There are two possible network topologies for realizing C-RAN architecture; one is tree topology and(More)
Chick embryonic motoneurons selectively grow out from the spinal cord as the first step of their selective axonal growth. In order to detect the molecules responsible for motoneuron outgrowth from the cord, we produced and immunohistochemically screened many monoclonal antibodies (MAbs) against cord and somite. We found that two of them, called M7412 and(More)
In order to analyse the spinal tract formation at early stages of development in avian embryos, chick-quail spinal cord chimeras were prepared and species-specific monoclonal antibodies (MAb) were developed. MAbs CN, QN and CQN uniquely stained chick, quail, and both chick and quail nervous tissues, respectively. All three antibodies appeared to bind to the(More)
In order to meet the bandwidth requirements for the access network, many network operators nowadays have been rapidly expanding their fiber-to-the-home (FTTH) service area. In such an area, a passive double star (PDS) network, which shares one optical fiber with multiple subscribers by using a power splitter, is commonly deployed as an infrastructure for(More)
We report on the recent progresses in the wavelength-division-multiplexed passive optical network (WDM PON) based on the reflective semiconductor amplifiers (RSOAs), including the enhanced operable temperature range, effects of reflection and its mitigation methods, 10 Gb/s operation by using electronic equalizers and forward error-correction (FEC) codes,(More)
The end-to-end QoS of streaming video on a joint metro and access network is investigated. SUCCESS DWA PON is a highly scalable broadband access network, which can bridge current TDM PON and future WDM PON smoothly and cost-effectively. The IEEE 802.17 Resilient Packet Ring is an emerging MAN standard that designs for efficient packet-based traffic(More)
