We focus on the minimization of least square loss function under a k-sparse constraint encoded by $$\ell _0$$ pseudo-norm. This is non-convex, non-continuous and NP-hard problem. Recently, for penalized form (sum penalty term), relaxation has been introduced which strong results in terms minimizers. continuous does not change global minimizers, among other favorable properties. The question tha...

Engaging parents as advocates for school success in the home is particularly important for English Language Learners (ELL). Tapping into the experiences of ELL parents in their own lives about schooling and literacy is a resource educators can use to increase parental involvement. This article describes the stories of two parents and compares their experiences with schools, their personal views...

BACKGROUND Reproducible and repeatable assessment of right heart function is vital for monitoring congenital and acquired heart disease. There is increasing evidence for the additional value of myocardial deformation (strain and strain rate) in determining prognosis. This study aims to determine the reproducibility of deformation analyses in the right heart using cardiovascular magnetic resonan...

RNA polymerase II elongation factor ELL was recently purified from rat liver as a component of a multiprotein complex containing ELL and three ELL-associated proteins (EAPs) of approximately 45 (EAP45), approximately 30 (EAP30), and approximately 20 (EAP20) kDa (Shilatifard, A. (1998) J. Biol. Chem. 273, 11212-11217). Cloning of cDNA encoding the EAP30 protein revealed that it shares significan...

The paper addresses the analysis of a single multiplexing node in ATM networks. It presents analyti al models for evaluating the performan e parameters of a multiplexer that has N identi al ON-OFF type input sour es and an output hannel with nite bu er. The hannel speed is assumed to be an integer times of the sour e speed in ON state. A two dimensional Dis rete Time Markov Chain is introdu ed ...

Anticancer drugs often show complex mechanisms of action, including effects on multiple cellular targets. Detailed understanding of these intricate effects is important for the understanding of cytotoxicity. In this study, we examined apoptosis induction by ellipticines, a class of cytotoxic plant alkaloids known to inhibit topoisomerase II. The potent ellipticine derivative 6-propanamine ellip...

BACKGROUND Pixel-based multimodality tissue tracking (MTT) is a new noninvasive method for the quantification of cardiac deformation from cine image of MRI. The aim of this study is to validate bi-ventricular strain measurement by MTT compared to strain-encoding (SENC) MRI and harmonic phase (HARP) MRI in pulmonary hypertension (PH) patients. METHODS In 45 subjects (30 PH patients and 15 norm...
