The advent of reconfigurable nodal elements, such as Optical Add/Drop Multiplexers (OADM) and CrossConnects (OXC) for Wavelength Division Multiplexed (WDM) networks, has led to a myriad of possible network architectures for the optical layer. In this paper we describe different architectures for resilient ring and mesh based WDM networks, and compare these architectures from a conceptual viewpo...

ownload B4 is unusual among receptor tyrosine kinases because some isoforms can be efficiently cleaved at the a membrane to release a soluble intracellular domain. The cleavage product has high kinase activity mes to the nucleus. A screen for proteins that associate with the ErbB4 intracellular domain identified ate interactors including ITCH, WWP2, Nucleolin, and Krab-associated protein 1 (Kap...

We have determined silicon self-diffusivity at temperatures 735-875 degrees C based on the Raman shift of longitudinal optical phonon frequencies of diffusion annealed 28Si/30Si isotope superlattices. The activation enthalpy of 3.6 eV is obtained in such low temperature diffusion annealing. This value is significantly smaller than the previously reported 4.95 eV of the self-interstitial mechani...

HST ultra-violet and ground-based optical spectroscopy are presented for DI 1388, an early-type star in the Magellanic Bridge. These data have been supplemented with H I radio mapping of its environment. The spectroscopy shows interstellar components at LSR velocities of 0, 90 and 200 km s-l corresponding to the local ISM, a high velocity cloud and the Magellanic Bridge ISM, respectively. The l...

HAKIJTA, KEKJI. Degree of Bilingualism and Cognitioe Ability in Mainland Puerto Rican Children. CHILD DEVELOPMENT, 1987,58,1372-1388. The relation between degree of bilingualism and cognitive ability was assessed longitudinally in low-income background Puerto Rican elemenschool children in the United States. AI1 subjects were enrolled in a transitional bilingual education program. 83 subjects, ...

Phytoncides are organic compounds, produced by plants in order to protect them from different microorganisms. Over the years a number of plants and their extracts are subjected to investigation of their antibacterial properties. The increase in the number of side reactions caused by antibiotics, and other drugs used in medical practice, turned back the attention of many scientists to studies of...
