The surface species formed following acetylene adsorption on Pd( 1 1 1) a t 300 K is identified as a vinylidene. It is oriented with its carbon+arbon axis tilted at -50’ to the surface normal which allows overlap between molecular ‘lr orbitals and the surface d-orbitals. The carbon4arbon bond is slightly longer (by -0.03 A) than for adsorbed ethylene on Pd( 1 1 1). This assignment is consistent...

Many brain imaging procedures require the careful alignment of different sets of images obtained in the same individual. The available automatic methods for brain alignment are susceptible to improvement. This paper discusses briefly a new automatic method to reinstall the tilted orientation of head images, using surface symmetry as a prior.

Condensate harvesting is the phenomenon of obtaining water from vapor in humid air condensing on a surface. The idea passive technique with no additional energy consumption, yet condensation performance surface varies many parameters. This study analytically investigates vertical, tilted, and horizontal systems. First, viscous effects, inertia, gravitational forces are examined detail to expres...

PURPOSE To investigate the level of inaccuracy of retinal thickness measurements in tilted and axially stretched optical coherence tomography (OCT) images. METHODS A consecutive series of 50 eyes of 50 patients with age-related macular degeneration were included in this study, and Cirrus HD-OCT images through the foveal center were used for the analysis. The foveal thickness was measured in t...
