E. S. Kozlova,

In this work the "central" surface plasmon-polariton was obtained by using frequency dependent difference time-domain method for the TMpolarized light at 532 nm, which was propagating through the silver nano-strip, placed on silica glass in an aqueous medium. The height and width of nanostrip was equal to 20 nm and 215 nm respectively. The intensity of surface plasmon-polariton was 4 times high...

The endodermis in roots acts as a selectivity filter for nutrient and water transport essential for growth and development. This selectivity is enabled by the formation of lignin-based Casparian strips. Casparian strip formation is initiated by the localization of the Casparian strip domain proteins (CASPs) in the plasma membrane, at the site where the Casparian strip will form. Localized CASPs...

Associate Professor, Graduate Aeronautical laboratories, California Institute of Technology, Pasadena, Calif. The tip velocity of a crack propagating through a vi scoelastic material depends on geometry, apptied toad and its history , and material properties. A consideration of the work done by the unloading tractions at the crack tip shows that, f or a large crack propagating throitgh an infin...

one of the problems in the ground-based circular synthetic aperture radar is the dependence of the azimuth resolution to the antenna rotation radius and operational limitation of increasing it. to enhance the image quality in azimuth, model-based image formation through three methods: matched filter, inverse filter and optimum filter is suggested and analyzed. for the purpose of comparison, thr...

We have studied the effect of oxidation on the propagation loss and surface roughness of silicon-on-oxidized-porous-silicon strip waveguides fabricated using proton-beam irradiation and electrochemical etching. A thin thermal oxide is formed around the core of the waveguide, enabling the symmetric reduction of core size and roughness on all sides. Significant loss reduction from about 10 dB/cm ...

Plants achieve mineral ion homeostasis by means of a hydrophobic barrier on endodermal cells called the Casparian strip, which restricts lateral diffusion of ions between the root vascular bundles and the soil. We identified a family of sulfated peptides required for contiguous Casparian strip formation in Arabidopsis roots. These peptide hormones, which we named Casparian strip integrity facto...

Good algorithms exist for solving the 2D rectangular strip packing problem when the objective is to minimize the amount of wasted material. However, in some applications other criteria are also important. We describe new heuristics for strip packing that optimize not only for wastage, but also for the efficient use of the cutting equipment, by minimizing the number of independent cuts required ...

Photorealistic rendering methods have been at the centre of much computer graphic research and remain in that position to date. The aim of photorealism is to produce computer graphic images that cannot be distinguished from photographs. Such methods have produced impressive results, and in some cases the aim has been met. However, photorealism is not always a desirable goal, sometimes a hand-dr...

deficiency. It is not applicable to newborn or mass screening with use of ifiterpaper specimens, but is satisfactory for liquid urine screening. In one variant of sulfite oxidase deficiency, due to a defect of its molybdate cofactor metabolism, the concentration of uric acid in serum is decreased. Thus, an unexplained low serum uric acid, especially in a young patient with neurologic abnormalit...

In this paper we introduce a simple and efficient scheme for encoding the connectivity and the stripification of a triangle mesh. Since generating a good set of triangle strips is a hard problem, it is desirable to do this just once and store the computed strips with the triangle mesh. However, no previously reported mesh encoding scheme is designed to include triangle strip information into th...
