PURPOSE In the present study, the authors examined lexical naming in children with cochlear implants (CIs). The goal was to determine whether children with CIs have deficits in lexical access and organization as revealed through reaction time in picture-naming and verbal fluency (VF) experiments. METHOD Children with CIs (n = 20, ages 7-10) were compared with 20 children with normal hearing (...

This paper presents the modeling of high speed distributed networks characterized by S-parameters frequency data using rational Krylov fitting (RKFIT) algorithm. Numerical examples illustrate effectiveness method to compute stable approximation that fit given data. In addition, it is shown RKFIT has some advantages when compared well-established Vector Fitting (VF) method, such as more accurate...

1. In the unanesthetized spinal cord, conditioning stimulation of low-threshold afferents (below 1.3 times threshold strength) in the biceps semitendinosus (BST) nerve often reduced the peak amplitude of the monosynaptic Ia EPSPs evoked in gastrocnemius motoneurons without affecting the monosynaptic component of the EPSPs evoked by stimulation of the ipsilateral ventral funiculus (VF) in the th...

Oil–water two-phase flow as a typical type widely exists in various industrial processes and the accurate measurement of oil volume fraction (VF) plays significant role transporting separating oil–water mixture processes. Electrical impedance tomography (EIT) merging technology with advantages noninvasive, low cost, real-time is applied field to measure VF for different types flows. However, pr...

PURPOSE The cumulative sum (CUSUM) is proposed and tested in a group of glaucoma patients and healthy subjects as a method for monitoring disease progression and for identifying clinically significant step changes in visual structure or function. METHODS The CUSUM procedure is the recommended method for the timely detection of small step changes in manufacturing process control. The CUSUM pro...

BACKGROUND Dynamically induced heterogeneities of repolarization may lead to wave-front destabilizations and initiation of ventricular fibrillation (VF). In a computer modeling study, we demonstrated that specific sequences of premature stimuli maximized dynamically induced spatial dispersion of refractoriness and predisposed the heart to the development of conduction block. The purpose of this...

BACKGROUND Ventricular tachycardia (VT) and ventricular fibrillation (VF) are the most serious cardiac arrhythmias that require quick and accurate detection to save lives. Automated external defibrillators (AEDs) have been developed to recognize these severe cardiac arrhythmias using complex algorithms inside it and determine if an electric shock should in fact be delivered to reset the cardiac...

Arrhythmias correlate with disorders of either K(2+) channels in sarcolemma or calcium modulating system in sarcoplasmic reticulum which handles Ca(2+) intracellularly. We hypothesized that an activated endothelin (ET) signaling pathway, which may be associated with an alteration of K(+) channels and Ca(2+) uptake activity in the myocardium, participated in the exaggerated ventricular fibrillat...

PURPOSE We measured macular inner retinal layer thicknesses using frequency-domain optical coherence tomography (fd-OCT) and correlated these measures with visual field (VF) in eyes with temporal hemianopia from chiasmal compression and band atrophy (BA) of the optic nerve. METHODS Macular fd-OCT scans and VFs were obtained from 33 eyes of 33 patients with temporal hemianopia and 36 control e...

BACKGROUND Trabeculectomy is frequently performed in patients with glaucoma who are deteriorating, although its effects on rates of visual field (VF) progression are not fully understood. We studied the rate of VF progression post trabeculectomy comparing with medically treated patients matched for VF loss. METHODS Medical records of patients who underwent trabeculectomy alone or combined wit...
