BACKGROUND Significant paravalvular aortic regurgitation (PAR) after transcatheter aortic valve implantation (TAVI) is associated with negative clinical consequences. We hypothesize that increased eccentricity of the aortic annulus is associated with greater PAR. METHODS Patients with severe aortic stenosis underwent multidetector computed tomography (MDCT) before successful TAVI with the Med...

The star HD 69830 exhibits radial velocity variations attributed to three planets as well as infrared emission at 8 − 35μm attributed to a warm debris disk. Previous studies have developed models for the planet migration and mass growth (Alibert et al. 2005, 2006) and the replenishment of warm grains (Wyatt et al. 2007). In this paper, we perform n-body integrations in order to explore the impl...

In a series of papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. However, for certain combinations of the masses and the orbital elements, the secular part of the solution failed. In the present paper, we derive a new solution for the secular part of the inner eccentricity, which corrects the pre...

ABSTRACT By means of high-resolution hydrodynamical, three-dimensional calculations with nested-meshes, we evaluate the eccentricity reached by a low-mass, luminous planet embedded in an inviscid disc constant thermal diffusivity and subjected to forces. We find that cell size at most 1/10th region heated is required get converged results. When planet’s luminosity supercritical, it reaches orde...

Visual search rate was used to assess attentional resources required for detection of opposing motions defined either by luminance or by modulations of texture contrast, flicker, or size. Though luminance-based targets were detected quickly, search through second-order motion was slow. Control experiments ruled out stimuli visibility, complexity, eccentricity sensitivity, and attributes of the ...

Tidal dissipation within a short-period transiting extrasolar planet perturbed by a companion object can drive orbital evolution of the system to a so-called tidal fixed point, in which the apsidal lines of the transiting planet and its perturber are aligned, and for which variations in the orbital eccentricities of both planet and perturber are damped out. Maintenance of the fixed-point apsida...

This paper presents a computational method for detecting vibrations related to eccentricity in ultra precision rotation devices used for nano-scale manufacturing. The vibration is indirectly measured via a frequency domain analysis of the signal from a piezoelectric sensor attached to the stationary component of the rotating device. The algorithm searches for particular harmonic sequences assoc...

Let G be a connected graph. The multiplicative Zagreb eccentricity indices of G are defined respectively as Π1(G) = ∏ v∈V (G) ε 2 G(v) and Π ∗ 2(G) = ∏ uv∈E(G) εG(u)εG(v), where εG(v) is the eccentricity of vertex v in graph G and εG(v) = (εG(v)) . In this paper, we present some bounds of the multiplicative Zagreb eccentricity indices of Cartesian product graphs by means of some invariants of t...

If the Moon’s spin evolved from faster prograde rates, it could have been captured into a higher spin–orbit resonance than the current 1:1 resonance. At the current value of orbital eccentricity, the probability of capture into the 3:2 resonance is as high as 0.6, but it strongly depends on the temperature and average viscosity of the Moon’s interior. A warmer, less viscous Moon on a higher ecc...

This paper proposes the eccentric problem in the coiling process of cold rolling mills. The wavelets multiresolution control method is designed: A wavelets multi-resolution controller is introduced in the control cycle of coiling tension control, whose purpose is to acquire the element caused by periodically change of the coiling eccentricity. Then the signal without effectiveness of the coilin...
