PURPOSE To quantitatively evaluate the impact of carotid stent cell design on vessel scaffolding by using patient-specific finite element analysis of carotid artery stenting (CAS). METHODS The study was organized in 2 parts: (1) validation of a patient-specific finite element analysis of CAS and (2) evaluation of vessel scaffolding. Micro-computed tomography (CT) images of an open-cell stent ...

This paper is the first of a two part series. In this paper, we first prove that the variety of dually quasi-De Morgan Stone semi-Heyting algebras of level 1 satisfies the strongly blended $lor$-De Morgan law introduced in cite{Sa12}. Then, using this result and the results of cite{Sa12}, we prove our main result which gives an explicit description of simple algebras(=subdirectly irreducibles) ...

Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axles and also for creating internal profiles such as rifling the gun barrels. The radial forging of tube is usually performed over a mandrel to create an internal profile and/or size the internal diameter. Most of the previous studies conducted on the radial forging process have u...

The catenary degree of an element s of a cancellative commutative monoid S is a nonnegative integer measuring the distance between the irreducible factorizations of s. The catenary degree of the monoid S, defined as the supremum over all catenary degrees occurring in S, has been heavily studied as an invariant of nonunique factorization. In this paper, we investigate the set C(S) of catenary de...

Several organisms, including Drosophila melanogaster, are apparently devoid of DNA methylation. This might reflect a highly restricted activity of DNA methyltransferases, a loss of methyltransferase activity during evolution or the dispensability of DNA methylation due to an efficient substitute mechanism. Vestiges of a Drosophila DNA methylation system have been identified recently. We show he...

Uninorms were introduced by Yager and Rybalov [13] as a generalization of triangular norms and conorms. We ask about properties of increasing, associative, continuous binary operation U in the unit interval with the neutral element e ∈ [0, 1]. If operation U is continuous, then e = 0 or e = 1. So, we consider operations which are continuous in the open unit square. As a result every associative...

The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, the finite element meshes should consider the size and histological features of the target structures. However, it is possible to verify that some methods or tools used to gener...

MKT0000528 › With recent improvements in the efficiency of integral equation solutions it is now possible to combine the integral equation procedure with the finite element method (FEM) in a hybrid Finite Element Boundary Integral approach (FEBI) [1]. In electromagnetics the FEM is a general purpose technique that solves for volumetric electric fields and can be used to accurately characterize ...

The paper presents an analytical formulation of an element removal algorithm based on dynamic equilibrium and the resulting transient change in system kinematics. The algorithm is implemented into an open-source finite element code, is numerically validated using a benchmark problem with simple element removal criteria, and is able to capture the effect of uncertainty in member capacity. Realis...

A new insertion element present in two alleles, designated IS1635.1 and IS1635.2, was identified on a plasmid of a Yersinia intermedia strain by hybridization with the Yersinia enterocolitica pYV virulence plasmid. IS1635.1 and IS1635.2 are 861 bp long, carry imperfect inverted terminal repeats and possess a single open reading frame encoding a putative transposase of the IS6 family. A truncate...
