Redshifted absorption proÐles that resemble the high-velocity circumstellar gas features in the spectrum of b Pictoris have been detected in IUE data for the 10 Myr old Herbig Be star, HD 100546, on 1995 March 7. In addition to Mg II, Si II, and other refractory species similar to those seen in b Pic, the HD 100546 spectra are rich in accreting gas proÐles from neutral atomic gas, including C I...
Transition-metal diboride thin films, which have high melting points, excellent hardness, and good chemical thermal conductivity, severely suffer from rapid oxidation in air. Here, we explore the influence of varying B content resulting nanostructure change on properties TiBx with x = 1.43, 2.20, 2.70. Results show that all as-deposited layers columnar structure. The column boundaries TiB2.20 T...
LIN-44/Wnt and LIN-17/Frizzled (Fz) function in a planar cell polarity (PCP)-like pathway to regulate the asymmetric B cell division in Caenorhabditis elegans. We observed asymmetric localization of LIN-17/Frizzled (Fz) and MIG-5/Dishevelled (Dsh) during the B cell division. LIN-17::GFP was asymmetrically localized within the B cell prior to and after the B cell division and correlated with B c...
