The Resilience Scale (RS) was developed by Wagnild and Young (1993) to measure a personality characteristic or coping resource that facilitates adaptation. The RS, however, has not been evaluated with foreign-born populations. Therefore, the purpose of this study was to report the factor structure, internal consistency, and concurrent validity of a Russian(More)
Inappropriately large interelectrode spacing may result in significant errors of localization and erroneous measurements of amplitudes, due to aliasing. Oversampling with very large numbers of scalp electrodes is impractical. We present a generally applicable method for determination of optimal interelectrode spacing. This optimal spacing is computed from(More)
Cerebral cortical function was prospectively examined by electroencephalography (EEG) in 3 subgroups of 257 infants at risk for sudden infant death syndrome (SIDS). Group 1 consisted of apparently healthy infants with near-miss SIDS episodes; Group 2 consisted of siblings of SIDS victims; and Group 3 consisted of neurologically suspect infants with apnea.(More)
Artificial neural network (ANN) based signal processing methods have been shown to have significant robustness in processing complex, degraded, noisy, and unstable signals. A novel approach to automated electromyogram (EMG) signal decomposition, using an ANN processing architecture, is presented in this paper. Due to the lack of a priori knowledge of motor(More)
We have presented a new method for the decomposition of clinical electromyographic signals, NNERVE, which utilizes a novel "pseudo-unsupervised" neural network approach to signal decomposition. In this paper, we present a detailed performance analysis. We present definitions for quantitative performance criteria. NNERVE is shown to be highly reliable over a(More)
The voltage measured was that induced in a measuring coil from 3 different commercially available magnetic stimulators. The strongest stimulus was from the Cadwell, followed by Novametrix and then Digitimer. The Digitimer and Novametrix produced a monophasic pulse, whilst the Cadwell stimulator produced a polyphasic pulse, all measured by an induction coil.(More)
Four patients with human-immuno-deficiency-virus-associated neurological disease were treated with 3'-azido-3'-deoxythymidine (AZT). Three (two with chronic dementia, and one with chronic dementia and peripheral neuropathy) improved as assessed by clinical examination, psychometric tests, nerve conduction studies, and/or positron emission tomography; there(More)
OBJECTIVE Necrotizing enterocolitis (NEC) is associated with high morbidity and mortality among infants admitted for intensive care. The factors associated with mortality and catastrophic presentation remain poorly understood. Our objective was to describe the factors associated with mortality in infants with NEC and to quantify the degree to which(More)
Thermoregulatory and emotional sweating can be distinguished in humans. While the first is organized via feed back mechanisms involving thermoreceptors, thermoregulatory centers in the brain and the effector system (sympathetic nervous system and sweat glands), the latter is generated directly by cortical and limbic mechanisms without any feed back. Sweat(More)
Stretching of human thenar muscle was carried out using mechanical stimuli of different amplitudes and velocities in 50 normal subjects. Amplitudes of early M1 and late M2 reflex responses as well as cortical evoked potentials were recorded. M1 and M2 increased with a larger mechanical stimulus. Steeper mechanical stimuli generated larger M1 amplitudes,(More)
