Method The pre and one-year postoperative data;-{Functional Class (FC), cardiothoracic ratio (CTR) in chest x-ray, and echocardiographically Left atrium (LA), Right atrium (RA), Right ventricle (RV), left ventricle (LV), & Pulmonary Artery (PA) dimensions, PAP, tricuspid regurgitation (TR)}, of 50 patients who had Mitral valve replacement (MVR) for MS with PAH, were retrospectively analysed for...

There is a quadratic-time algorithm that determines conjugacy between finite subsets in any torsion-free hyperbolic group. Moreover, in any k-generator, δ-hyperbolic group Γ, if two finite subsets A and B are conjugate, then x−1Ax = B for some x ∈ Γ with ‖x‖ less than a linear function of max{‖γ‖ : γ ∈ A∪B}. (The coefficients of this linear function depend only on k and δ.) These results have i...

We introduce the notion of the mean-set (expectation) of a graph(group-) valued random element ξ and prove a generalization of the strong law of large numbers on graphs and groups. Furthermore, we prove an analogue of the classical Chebyshev’s inequality for ξ. We show that our generalized law of large numbers, as a new theoretical tool, provides a framework for practical applications; namely, ...

Choosing the best hospitals or avoiding the worst hospitals is important to patients, physicians, and insurers. There is a wealth of publicly reported quality data to use in making those choices, but that data is presented in ways that may conceal important information. We develop three models of how individuals might use the available data in choosing a hospital and present a model that relies...

In this paper, we study the privacy-preserving decision tree building problem on vertically partitioned data. We made two contributions. First, we propose a novel hybrid approach, which takes advantage of the strength of the two existing approaches, randomization and the secure multi-party computation (SMC), to balance the accuracy and efficiency constraints. Compared to these two existing appr...

Roughly 120,000 persons over 15 years of age in Mexico are believed to have tuberculosis.6 About 50 per cent of these have been registered with the nation’s health services, the location of the remainder being unknown. Furthermore, in the past a large share of those registered have abandoned drug therapy before the end of six months, and only about half have received the benefits of the full on...

Digital fingerprinting of multimedia data involves embedding information in the content, and offers protection to the digital rights of the content by allowing illegitimate usage of the content to be identified by authorized parties. One potential threat to fingerprints is collusion, whereby a group of adversaries combine their in&vidual copies in an attempt to remove the underlying fingerprint...

Recently, collaborative image filtering based on groupbased sparse representation has gained a popularity in image restoration. BM3D frame [1], one of the first example of such a representation, utilizes both local sparsity of small size image patches and group-sparsity of collections of selfsimilar image patches. As a sparsifying transforms in the spatial and similarity domains, fixed transfor...

This paper presents a new algorithm for distributed garbage collection and outlines its implementation within the Network Objects system. The algorithm is based on a reference listing scheme augmented by partial tracing in order to collect distributed garbage cycles. Our collector is designed to be flexible thereby allowing efficiency, expediency and fault-tolerance to be traded against complet...
