Fractals are self-similar images. There are many techniques for generating fractals. IFS are one of them. IFS use a set of linear transformations for generation of fractals. We propose a method of modifying IFS such that non-linear transformations can be used for generating pleasant looking fractals. We also show a technique which ensures convergence of the fractal Images. Non-linear fractals h...

Intermediate filaments (IFs) are abundant structures found in most eukaryotic cells, including those in the nervous system. In the CNS, the primary components of neuronal IFs are alpha-internexin and the neurofilament triplet proteins. In the peripheral nervous system, a fifth neuronal IF protein known as peripherin is also present. IFs in astrocytes are primarily composed of glial fibrillary a...

Soy isoflavones (Ifs), which are natural phytoestrogens, have beneficial effects in cardiovascular disease. We have previously shown that genistein, the most active component of Ifs, inhibits pulmonary vascular structural remodeling and right ventricular hypertrophy induced by chronic hypoxia in male Wistar rats. This study aimed to evaluate the effects of Ifs on right ventricular and pulmonary...

BACKGROUND During ultrasound-guided radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC), high echoic areas due to RFA-induced microbubbles can help calculate the extent of ablation. However, these areas also decrease visualization of target tumors, making it difficult to assess whether they completely cover the tumors. To estimate the effects of RFA more precisely, we used an image ...

Intermediate filaments (IFs) are components of the cytoskeleton involved in most cellular functions, including cell migration. Primary astrocytes mainly express glial fibrillary acidic protein, vimentin, and nestin, which are essential for migration. In a wound-induced migration assay, IFs reorganized to form a polarized network that was coextensive with microtubules in cell protrusions. We fou...

We address here th e resolution of the so-called inverse problem for the iterated functions system (IFS). This problem has already been widely considered, and some studies have been performed for the affine IFS , using determin ist ic or stochast ic methods (simulated annealing or genetic algorithm). In dealing with the nonaffine IFS, the usual techniques do not perform well unless some a prior...

Two random iteration algorithms or \chaos games" for Iterated Function Systems on function spaces, namely IFS with grey level maps (IFSM), are described. The rst algorithm can be interpreted as a \chaos game in code space" and is guaranteed to work only in the case of nonoverlapping IFS maps. In the second algorithm, applicable to IFSM with overlapping IFS maps but aane grey level maps, the (no...

IFS Global non-hydrostatic simulations of mesoscale phenomena are possible with low computational cost with the “small planet” test bed available in the IFS at ECMWF. The dry non-hydrostatic dynamical core of ALADIN (Bubnova et al, 1995, Bénard et al. 2009) has been adapted to the IFS and a series of non-hydrostatic phenomena have been explored on a reduced-size sphere (Wedi and Smolarkiewicz, ...

The contribution of this paper is a new version of the escape time algorithm adapted to synthesize fractal images, identified with attractors of iterated function systems (IFS). The proposed synthesis algorithm is based on the use of shift dynamics, associated with one or another IFS. The novelty of the algorithm is grounded on two factors. Firstly, the strategy for the separation of extended d...
