We present a generalization of independent component analysis (ICA), where instead of looking for a linear transform that makes the data components independent, we look for a transform that makes the data components well fit by a tree-structured graphical model. Treating the problem as a semiparametric statistical problem, we show that the optimal transform is found by minimizing a contrast fun...

Editorial Source separation is not a new problem. We, human beings, as well as many other species, do it unconsciously at every instant of our lives. Our organisms receive a multitude of signals mixed together from the environment, and we are constantly uncovering the relevant ones in order to derive vital information to continue our lives. Other than the biological signals that are occurring a...

corticosteroid resistant and dependent nephrotic syndrome in children is a challenge and there are some difficulties in treating such patients. we reviewed the current studies that evaluated therapeutic role of a relatively new immunosuppressive drug “rituximab” in reducing proteinuria and reduction of relapse rate in less than 16 year old patients with non-responsive or steroid dependent nephr...

abstract: this paper considers the problem of scheduling n jobs on m unrelated parallel machines with sequence-dependent setup times. to better comply with industrial situations, jobs have varying due dates and ready times and there are some precedence relations between them. furthermore sequence-dependent setup times and anticipatory setups are included in the proposed model. the objective is ...

This study investigated how English as Foreign Language (EFL) learners with different learning styles (Field dependent and field independent) boost up their reading comprehension abilities as they develop their metacognitive skills. To conduct this research, 60 participants were randomly invited to sit PET (Preliminary English Test) to ensure homogeneity of the participants in terms of language...

Abstract We study the statefinder parameters of a cosmological model based on scale-dependent gravity. The effective Einstein field equations come from an average action. From dynamical system, we derive analytical expressions that improve convergence numerical solutions. determine for moderate redshift and compare them with well-known alternatives to ΛCDM.
