This paper presents a texture synthesis algorithm that was designed for the tile-less generation of large images of arbitrary size from small sample images. The synthesised texture shows features that are visually similar to the sample over a wide frequency range. The development of the algorithm aimed at achieving high quality results for a large range of natural textures, incorporation of the...

Liver is the largest internal organ in human body. It lies under right ribs just beneath right lung, shaped like a pyramid and divided into four different lobes. It is the only internal organ which has the property of regeneration of lost tissue. It plays major role in metabolism, emulsification of lipids and stores nutrients. Accurate segmentation of liver is still a challenge due to differenc...

Given a quiver algebra A with relations defined by a superpotential, this paper defines a set of invariants of A counting framed cyclic A-modules, analogous to rank-1 Donaldson–Thomas invariants of Calabi–Yau threefolds. For the special case when A is the non-commutative crepant resolution of the threefold ordinary double point, it is proved using torus localization that the invariants count ce...

The insular claustrum of the cat was studied using Kopsch modification of the Golgi technique. Neurons with or without dendritic spines were found. Among spiny neurons large pyramid-like cells with one main dendrite (S I type) appeared most frequently. Spindle-shaped neurons with two main dendrites (S II type) and multipolar ones (S III type) occurred much less frequently. Two types of aspimny ...

Pyramid-shaped InGaN/GaN micro-light-emitting diodes (μ-LEDs) were grown on a sapphire substrate using the selective area growth technique. A stable emission wavelength of single μ-LED pyramid at 412 nm was observed under an injection current from 0.05 to 20 mA, despite non-uniformity thickness and composition multiple quantum wells (MQWs) sidewall. An efficient carrier confinement and, thus, h...

We discuss the parallelization of a Velocity-Stress FDTD (VS-FDTD) code for the simulation of the propagation of mechanical waves in three-dimensional microstructures. The C++ code has been parallelized using MPI making extensive use of the Blitz++ library for local computation. We present numerical results for pyramid shaped domains, representing the tip of a focusing lens, that we have obtain...
