We newly propose a novel blind separation framework for SingleInput Multiple-Output (SIMO)-model-based acoustic signals using the extended ICA algorithm, SIMO-ICA. The SIMO-ICA consists of multiple ICAs and a fidelity controller, and each ICA runs in parallel under the fidelity control of the entire separation system. The SIMO-ICA can separate the mixed signals, not into monaural source signals...

Artery Arising from the Internal Carotid Artery I read with interest the article by Chan et al. They stated that there was a rare congenital anastomosis between the vertebral artery (VA) and internal carotid artery (ICA) with an absence of communication between the common carotid and cervical ICA. I, however, diagnose that there was an acquired occlusion of the ICA at its origin with a developm...

Because of the distance between the skull and brain and their different resistivities, electroencephalographic (EEG) data collected from any point on the human scalp includes activity generated within a large brain area. This spatial smearing of EEG data by volume conduction does not involve significant time delays, however, suggesting that the Independent Component Analysis (ICA) algorithm of ...

When exploiting independent component analysis (ICA) to perform blind source separation (BSS), it is assumed that sources are mutually independent. However, in practice, the latent sources are usually dependent to some extent. Subband decomposition ICA (SDICA) is an extension of ICA to admit source dependence. It assumes that each source is represented as the sum of some independent sub-compone...

BACKGROUND Despite a high prevalence of intracranial aneurysm (ICA) in autosomal dominant polycystic kidney disease (ADPKD), rupture events are rare. The current recommendations for ICA screening are based on expert opinions and studies with low levels of evidence. OBJECTIVES The aim of our study was to describe the attitudes of practicing nephrologists in Europe towards screening for ICA usi...

Independent Component Analysis (ICA) and Blind Source Separation (BSS) have become standard tools in multivariate data analysis. ICA continues to generate a flurry of research interest, resulting in increasing numbers of papers submitted to conferences and journals. Furthermore, there are many workshops and special sessions conducted in major conferences that focus on recent research results. T...

Wang, Yong G., and Stephen L. Lipsius. Genistein elicits biphasic effects on L-type Ca21 current in feline atrial myocytes. Am. J. Physiol. 275 (Heart Circ. Physiol. 44): H204–H212, 1998.—A perforated patch recording method was used to determine the effects of genistein (Gen), a protein tyrosine kinase (PTK) inhibitor, on basal L-type Ca21 current (ICa,L) in feline atrial myocytes. Gen (50 μM) ...

Independent Component Analysis (ICA) is a popular method for extracting independent features from visual data. However, as a fundamentally linear technique, there is always nonlinear residual redundancy that is not captured by ICA. Hence there have been many attempts to try to create a hierarchical version of ICA, but so far none of the approaches have a natural way to apply them more than once...

Linear independent component analysis (ICA) learns simple cell receptive fields fromnatural images.Here,we show that linear complexvalued ICA learns complex cell properties from Fourier-transformed natural images, i.e. two Gabor-like filters with quadrature-phase relationship. Conventional methods for complex-valued ICA assume that the phases of the output signals have uniform distribution. We ...
