prolapsed mitral valve syndrome is a common, benign disorder with prevalence of %0.3-6 in population. this syndrome also is known as barlows syndrome and flaapy mitral valve syndrome. prolapsed mitral valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. this malformation leads to incomplete closing of mitral valve and regurgitates the bloo...

In the work, we rebuild the masks of well-known interpolatory symmetric subdivision schemes-binary 2n-point interpolatory schemes, the ternary 4-point interpolatory scheme using only the symmetry and the necessary condition for smoothness and the butterfly scheme, and the modified butterfly scheme using the factorization property. 2006 Elsevier Inc.

This paper presents a butterfly physically unclonable function (PUF) implementation in SRAM-based field programmable gate arrays (FPGAs). To avoid output instability, we propose a delay difference test to identify reliable slices (mapped to which butterfly PUF cells are highly reliable) and then PUF reliability is significantly improved by selective mapping PUF cells to reliable slices, which i...

We present a simple model for synthesis of butterfly wing patterns. The model simulates the formation of eyespots as are called the rounded circular arrangements which appear in many butterfly species. We illustrate our results with the examples of Diatheria clymena and Automeris io species.

In this study, we are concerned with non-stationary interpolatory subdivision schemes with refinement rules which may vary from level to level. First, we derive a new class of interpolatory non-stationary subdivision schemes reproducing exponential polynomials. Next, we prove that non-stationary schemes based on the known butterfly-shaped stencils possess the same smoothness as the known Butter...

An electronic circuit realization of a modified Lorenz system, which is multiplier-free, is described. The well-known butterfly chaotic attractor is experimentally observed verifying that the proposed modified system does capture the essential dynamics of the original Lorenz system. Furthermore, we clarify that the butterfly attractor is a compound structure obtained by merging together two sim...
