This problem can be investigated using fluid structure interaction (FSI) simulations. However, few FSI investigations have been performed on patient specific aneurysms models. With the restriction of constant thickness, Valencia et al. have compared FSI with computational structural dynamics simulations. The difference in the maximum effective stress on the aneurysms was small, but the differen...

A Lie theoretic interpretation is given to a pattern with five-fold symmetry occurring in aperiodic Penrose tiling based on isosceles triangles with length ratios equal to the Golden Section. Specifically a B(∞) crystal based on that of Kashiwara is constructed exhibiting this five-fold symmetry. It is shown that it can be represented as a Kashiwara B(∞) crystal in type A4. Similar crystals wit...

The literature outlines several surgical techniques to restore inframmammary fold definition, but symmetry of the fold is often left to irreproducible procedures. We report our personal technique to restore the symmetry of the inframmammary fold during multistep breast reconstruction.

This note introduces a quantitative measure (S(G)) of the symmetry structure of a graph G. S(G) is called the index of symmetry of G and is a function of its structural information content and the order of its automorphism group. Properties of S(G) are examined and applications to special classes of graphs are presented. In particular, the index of symmetry of a class of alkanes is shown to be ...

BACKGROUND Hemodynamics play an important role in the development and progression of carotid atherosclerosis, and may be important in the assessment of plaque vulnerability. The aim of this study was to develop a system to assess the hemodynamics of carotid atherosclerotic plaques using subject-specific fluid-structure interaction (FSI) models based on magnetic resonance imaging (MRI). MATERI...

We discuss in this paper the numerical approximation of fluid-structure interaction (FSI) problems dealing with strong added-mass effect. We propose new semi-implicit algorithms based on inexact block-LU factorization of the linear system obtained after the space-time discretization and linearization of the FSI problem. As a result, the fluid velocity is computed separately from the coupled pre...

A b s t r a c t The radius of interaction between the struck proton and spectator nucleons is close to the radius of short-distance two-nucleon correlations in nuclear matter, which makes final state interaction (FSI) an important background to production of protons with large missing momentum. We present a simple classification of the dominant FSI effects in 4 He(e, e ′ p) scattering and ident...

Numerous of studies estimate the influence of climatic factors on food-grain crops as a proxy for integrated food security in different regions of India, conclude that climate change has a significant and negative impact on food security in India [13]. Few studies used agricultural productivity of food-grain and commercial crops to assess the climatic change impact on agricultural productivity ...

The degree of aromaticity of mono-substituted derivatives of benzene has beeninvestigated using a new index based on electric field gradient index, by using two mechanicalquantum methods with Gaussian 03. Two different basis sets have applied to study and theresults compared. This strategy has demonstrated that, due to violation of symmetry in have pisystems,how the degree of aromaticity can ha...
