Without Focal Adhesion Kinase (FAK), developing murine Schwann cells (SCs) proliferate poorly, sort axons inefficiently, and cannot myelinate peripheral nerves. Here we show that FAK is required for the development of SCs when their basal lamina (BL) is fragmentary, but not when it is mature in vivo. Mutant SCs fail to spread on fragmentary BL during development in vivo, and this is phenocopied...

ion is a gifted capability of human beings. Abstraction is a basic cognitive process of the brain at the meta cognitive layer according to the Layered Reference Model of the Brain (LRMB) (Wang, 2003a, 2007c; Wang, Liu, & Wang, 2003, 2006). Only by abstraction can important theorems and laws about the objects under study be elicited and discovered from a great variety of phenomena and empirical ...

The atmospheric boundary layer (BL) in tropical cyclones (TCs) connects deep convection within rainbands and the eyewall to the air–sea interface. Although the importance of the BL in TCs has been widely recognized in recent studies, how physical processes affect TC structure and intensity are still not well understood. This study focuses on a particular physical mechanism through which a TC-in...

of a dissertation at the University of Miami. Dissertation supervised by Professor Bruce Albrecht. No. of pages in text. (124) This dissertation investigates the impacts of meteorological factors and aerosol indirect effects on the costal marine stratocumulus (Sc) variations in the southeast Pacific, a region that has been largely unexplored and is a major challenge of the modeling community, t...

Continuous lidar observations of the top height of the boundary layer (BL top) have been performed at Leipzig (51.3 • N, 12.4 • E), Germany, since August 2005. The results of measurements taken with a compact, automated Raman lidar over a one-year 5 determination of the BL top are discussed. The most promising technique, the wavelet covariance algorithm, is improved by implementing some modific...

Bilayer (BL) MoSe2 films grown by molecular-beam epitaxy (MBE) are studied by scanning tunneling microscopy and spectroscopy (STM/S). Similar to monolayer (ML) films, networks of inversion domain boundary (DB) defects are observed both in the top and bottom layers of BL MoSe2, and often they are seen spatially correlated such that one is on top of the other. There are also isolated ones in the ...

AlxGa1−xN/GaN x 0.3 heterostructures with and without a high-temperature HT AlN interlayer IL have been grown on sapphire Al2O3 substrates and AlN buffer/Al2O3 templates by metal organic chemical vapor deposition. The effects of an AlN buffer layer BL grown on an Al2O3 substrate and an AlN IL grown under the AlGaN ternary layer TL on structural, morphological, and optical properties of the hete...

Abstract. Climate change is particularly noticeable in the Arctic. The most common type of cloud at these latitudes mixed-phase stratocumulus. These clouds occur frequently and persistently during all seasons play a critical role Arctic energy budget. Previous observations central (north 80∘ N) have shown high occurrence prolonged periods shallow, single-layer stratocumulus top boundary layer (...
