Ferlito A, Devaney KO, Rinaldo A, et al. Ear cholesteatoma versus cholesterol granuloma. Ann Otol Rhinol Laryngol 1997;106:79–85 This is an excellent histopathology-based review (no images) that defines and differentiates these two entities. Very interesting information. Authors reiterate that cholesteatoma is a misnomer: it is not a neoplasm (-oma), there are no cholesterol crystals (chole-), ...

We give sufficient conditions for the universality of tensor products fTnf #Rn : nANg of sequences of operators defined on Fréchet spaces. In particular we study when the tensor product Tf #R of two operators is chaotic in the sense of Devaney. Applications are given for natural operators on function spaces of several variables, in Infinite Holomorphy, and for multiplication operators on the al...

Chaos is a nonlinear behavior that shows chaotic and irregular responses to internal and external stimuli in dynamic systems. This behavior usually appears in systems that are highly sensitive to initial condition. In these systems, stabilization is a highly considerable tool for eliminating aberrant behaviors. In this paper, the problem of stabilization and tracking the chaos are investigated....

today we are facing with a turbulent world full of complexity and change. contemporary problems are too complicated for rational, logical solutions. they admit insights, not answers. chaos theory is a solution to reveal insights into the structure and the dynamics of complex systems. chaos theory is in formative stage, but we can use it in management practices. this article is about application...

analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. this paper compares the performance of chaos theory with anfis model and discusses ...

chaos theory discusses unstable and non-periodic behavior of non-linear fluctuating dynamicsystems. since evaporation level variations of lakes have a dynamic identity, chaos theory can have a uniquerole in collecting data of these variations. therefore it is an important and challenging problem in the field ofplanning and qualitative and quantitative management of urmia lake to verify whether ...

The Charged System Search (CSS) is combined to chaos to solve mathematical global optimization problems. The CSS is a recently developed meta-heuristic optimization technique inspired by the governing laws of physics and mechanics. The present study introduces chaos into the CSS in order to increase its global search mobility for a better global optimization. Nine chaos-based CSS (CCSS) methods...

In this paper, we study rational functions of the form [Formula: see text] with fixed and at least text], hold either or while other varies. We locate some homeomorphic copies Mandelbrot set in text]-parameter plane for certain ranges as well text]-plane text]-ranges. use techniques first introduced by Douady Hubbard [1985] that were applied subfamily Devaney [2006]. These involve polynomial-li...

Atmospheric flows, an example of turbulent fluid flows, exhibit fractal fluctuations of all space-time scales ranging from turbulence scale of mm sec to climate scales of thousands of kilometers – years and may be visualized as a nested continuum of weather cycles or periodicities, the smaller cycles existing as intrinsic fine structure of the larger cycles. The power spectra of fractal fluctua...
