A study was conducted to assess the relative impact of partial sleep deprivation (restriction to 4 h sleep before testing) and full sleep deprivation (no sleep on the night before testing) on 2 h of simulated driving, compared with an alcohol treatment (mean blood alcohol content = 0.07%). Data were collected from the 64 male participants on the primary driving task, psychophysiology (0.1 Hz he...

Purpose Photoaversion (PA) is a disabling and ubiquitous feature of achromatopsia (ACHM). We aimed to help define the characteristics of this important symptom, and present the first published assessment of its impact on patients' lives, as well as quantitative and qualitative PA assessments. Methods Molecularly confirmed ACHM subjects were assessed for PA using four tasks: structured survey ...

BACKGROUND Statistical numeracy is essential for understanding health-related risks and making informed medical decisions. However, this concept has not been investigated with probabilistic national samples or compared cross-culturally. We sought (1) to investigate differences in the level of statistical numeracy between 2 countries with different educational and medical systems-the United Stat...

The primary goal for evaluation techniques is to conduct valid and reliable tests which provide data for research, development, and quality control during deployment of the developed algorithms. Quality assessment of watermarked audio tracks is a significant challenge. No single objective metric to quantify the quality of an audio track AbstRAct Methods for evaluating the quality of watermarked...

BACKGROUND Subjective cognitive impairments are frequent, but poorly understood in patients with chronic fatigue. We hypothesized that maladaptive metacognitive beliefs at baseline were associated with baseline subjective cognitive impairments, that they predict subjective cognitive impairments at treatment termination, and that a reduction in maladaptive metacognitive beliefs was associated wi...

To assess inapparent visual field defects in patients with multiple sclerosis free from optic neuritis. During 5 years period 120 patients with multiple sclerosis were examined at the University Department of Ophthalmology, Zagreb University Hospital Center. They were divided into three groups with 40 patients each: patients with acute unilateral optic neuritis, referred to ophthalmologist and ...

In this paper, we employ normalized modulation spectral analysis for voice pathology detection. Such normalization is important when there is a mismatch between training and testing conditions, or in other words, employing the detection system in real (testing) conditions. Modulation spectra usually produce a high-dimensionality space. For classification purposes, the size of the original space...
