OBJECTIVES The aim of the study was to analyze the long-term results of congenital subvalvar aortic stenosis (SAS) relief and the risk factors associated with recurrence and reoperations. METHODS Between January 1960 and March 2005, 190 patients underwent surgical correction for discrete (n=140) and tunnel (n=50) congenital subaortic stenosis. There were 115 male and 75 female patients rangin...

S URGICAL treatment of stenotic valvular lesions' requires definitive diagnosis. The clinical differentiation of aortic stenosis from congenital subaortic stenosis has always presented certain difficulties. Such factors as age of onset, history of rheumatic fever, and the quality of the second aortic heart sound have aided in the differentiation.2-5 Review of the literature indicates that subao...

In the last few decades many papers appeared in the statistical literature on the discretization of continuous distributions. The main reasons for discretizing a continuous distributions are two fold, namely, (i) the discrete analogue of a continuous distribution provide probability mass function (pmf) that can compete with the classical discrete distributions commonly used in the statistical a...

We report large scale Monte Carlo simulations of the equilibrium discrete Laplacian roughening (dLr) model, originally introduced as the simplest one accommodating the hexatic phase in two-dimensional melting. The dLr model is also relevant to surface roughening in molecular beam epitaxy (MBE). Our data suggest a single phase transition, possibly of the Kosterlitz-Thouless type, between a flat ...

This paper extends the e cient factorization of the Gabor frame operator developed by Strohmer in [17] to the Gabor analysis/synthesis operator. The factorization provides a fast method for computing the discrete Gabor transform (DGT) and several algorithms associated with it. The factorization algorithm should be used when the involved window and signal have the same length. An optimized imple...

What is believed to be a new analysis algorithm to carry out profile measurement with low computational complexity and less noise sensitivity is presented. First, a discrete cosine transform (DCT)-based representation method is introduced to express the height distribution of a 3D surface. Then a novel shift estimation algorithm, called the DCT-based shift estimation (DCT-SE), is presented to r...

In this paper we suggest an extension of tile generalized power series distributions by including an additional parameter p. It has a natural interpretation in terms of both "zeroinflated" proportion and correlation coefficient. A new concept of p-type lack of memory property is introduced. The proposed new discrete distributions are candidates for modeling of correlated count data which exhibi...

We study the statistical mechanics of the one-dimensional discrete nonlinear Schrödinger (DNLS) equation with saturable nonlinearity. Our study represents an extension of earlier work [Phys. Rev. Lett. 84, 3740 (2000)] regarding the statistical mechanics of the one-dimensional DNLS equation with a cubic nonlinearity. As in this earlier study, we identify the spontaneous creation of localized ex...
