Comprehensive studies were carried out to investigate the light extraction efficiency of thin-film flip-chip (TFFC) light-emitting diodes (LEDs) with anatase TiO(2) microsphere arrays by employing the finite-difference time-domain method. The quantum well position and the resonant cavity effect were studied to obtain optimum light extraction for the planar TFFC LED. Further enhancement in light...

BACKGROUND AND PURPOSE The purpose of this study was to measure the changes in the intraaneurysmal fluid pressure and parent vessel flow characteristics resulting from packing the aneurysmal sac with hydrogel-coated coils. METHODS Platinum coils coated with an expansible hydrogel were used to embolize a silicone model of the basilar tip aneurysm. The intraaneurysmal fluid pressure was measure...

Packing of monosized spheres in a cylindrical container of a fixed diameter is a frequently discussed subject in recent studies. It is motivated by the high applicability of these models, particularly by the advances in nanomaterial science and engineering, associated with the development of hierarchically ordered matters of specific structures and properties. Their features strongly depend on ...

Using replica density functional theory and Monte Carlo computer simulations we investigate a system of annealed hard spherocylinders adsorbed in a matrix of quenched hard spheres. Theoretical predictions for the partition coefficient, defined as the ratio of density of rods in the matrix and that in a reservoir, agree well with simulation results. Theory predicts the isotropic-nematic transiti...

The Split Packing algorithm [14, 24] is an offline algorithm that packs a set of circles into shapes (triangles and squares) at an optimal packing density. In this paper, we develop an online alternative to Split Packing to handle an online sequence of insertions and deletions, where the algorithm is allowed to reallocate circles into new positions at a cost proportional to their areas. The alg...

Despite the suitability of various lattice geometries for coarse-grained modeling of proteins, the actual packing geometry of residues in folded structures has remained largely unexplored. A strong tendency to assume a regular packing geometry is shown here by optimally reorienting and superimposing clusters of neighboring residues from databank structures examined on a coarse-grained (single-s...

the model fluids containing hard ellipses (hes) and gay-berne (gb) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using monte carlo simulation, nvt ensemble. the dependency of fluid pressure with respect to the wall distances is studied. the oscillatory behaviors are seen in this quantity against wall ...

A new class of spherical codes called wrapped spherical codes is constructed by “wrapping” any sphere packing in Euclidean space onto a finite subset of the unit sphere in one higher dimension. The mapping preserves much of the structure of , and unlike previously proposed maps, the density of wrapped spherical codes approaches the density of as the minimum distance approaches zero. We show tha...
