Scanning tunneling microscopy studies are integrated with development of a realistic atomistic model to both characterize and elucidate the complex mounded morphologies formed by deposition of Ag on Ag(111) at 150 and 180 K. Threefold symmetric lateral shapes of islands and mounds are shown to reflect the influence of a nonuniform step edge barrier inhibiting interlayer transport. Modeling of s...

Intravenous pressure bag Theatre table TECHNiQUE An intravenous fluid pressure bag is placed under the pelvis at the start of the procedure. To protect the patient from direct contact with the bag and the plastic components of the device, the bag is placed under a gel pad. The pump protrudes over a lateral edge of the operating table. Having reached the point when the modified position is requi...

A 2+1 dimensional PDE traveling wave model describing spatial-lateral dynamics of edge-emitting broad area semiconductor devices is considered. A numerical scheme based on a split-step Fourier method is presented and implemented on a parallel compute cluster. Simulations of the model equations are used for optimizing of existing devices with respect to the emitted beam quality, as well as for c...

Microscopic appearances Sections showed a small circumscribed but unencapsulated oxyphil cell adenoma on the lateral edge of the caruncle. It appeared to originate from and replace the surface epithelium (Fig. I). The tumour was composed of distinctive eosinophilic granular cells arranged in solid cords, tubules, and acini (Fig. 2). A small group of lacrimal acini was present in the subjacent d...

A two terminal spin-injection device is fabricated using a nanostencil process with a Co–Cu–Co stack. The stack can be deposited both by sputtering and by electron-beam evaporation. A better edge definition is observed in evaporation-deposited films under cross section transmission electron microscopy. Both methods succeeded in producing junctions with sub-100 nm lateral dimensions and show spi...

We consider the effect of nucleation on a one-dimensional stepped surface, finding that step-flow growth is metastable for any strength of the additional step-edge barrier. The surface is made unstable by the formation of a critical nucleus, whose lateral size is related to the destabilization process on a high-symmetry surface. Arguments based on a critical nucleus of height two, which suggest...

We study the electronic transport through a quantum wire (QW) with a strong side coupled quantum dot (QD). We obtain a linear conductance with lateral peaks when the gate voltage, is located near the edge of the conduction band. The calculated density of states shows, that these peaks are associated with renormalized localized levels out side of the conduction band. These results are compatible...

Two specimens of an undescribed species of pontoniine shrimp of the genus Periclimenaeus Borradaile 1915 from Maui Island, Hawaiian Islands, are described and illustrated, raising to three the number of species known from the Hawaiian Islands. The new species is remarkable for the greatly reduced molar process and sharp lateral cutting edge on the major second pereiopod dactyl and most closely ...

We have constructed an atomic force microscope enabling one to image the topography of a sample, and to monitor simultaneously ultrasonic surface vibrations in the MHz range. For detection of the distribution of the ultrasonic vibration amplitude, a part of the position-sensing light beam reflected from the cantilever is directed to an external knife-edge detector. Acoustic images taken on the ...

Suggested scheme for the treatment of onychomycosis A stepped therapeutic approach to the treatment of onychomycosis is suggested. The risks of failure of treatment include the fungal involvement of the lunula portion, the lateral edge of the nail and the subungual area. Infection of the subungual area may lead to extensive onycholysis or dermatophytoma presenting as a hard subungual mass or as...
