BACKGROUND A study was performed to analyze time-of-day variations of different indicators of attention and their interrelations. METHODS After a sufficiently long all-night sleep 12 healthy non-sleep-deprived subjects ran through a test battery (Stanford Sleepiness Scale, Visual Analogue Scale, Critical Flicker Fusion Test [CFF], Visualization Test, Number Facility Test, Reaction Time, Pupil...

Most information overload research has been done in cognitive load contexts and predominantly focused on normative decision-making process. This study suggests the need to divide information load into two dimensions: cognitive load that is found in prior research, and emotional load as a new dimension. The emotional dimension can affect the information overload that results from the prevalence ...

In this study, the validity of the approximation used in the modeling of resonant inverter tuning loop is discussed. With this approach, the phase-frequency relation of a resonant load around load resonant frequency can be expressed as a linear function for a reasonably high quality factor load. Results are verified by simulations.

Load balancing algorithms improve a program's performance on unbalanced datasets, but can degrade performance on balanced datasets, because unnecessary load redistributions occur. This paper presents a cost-eeective data-parallel load balancing algorithm which performs load redistributions only when the possible savings outweigh the redistribution costs. Experiments with a data-parallel polygon...

The paper shows that the excessive value of the dead load factor in the ultimate load requirements of the current structural design code implies a size effect. The size effect implied, however, does not have a rational form; it cannot distinguish among various types of failure in which very different size effects apply. This size effect partly compensates for the absence of the actual size effe...

Late-onset Alzheimer's disease (LOAD) is the most common form of dementia in the elderly. LOAD has a complex and largely unknown etiology with strong genetic determinants. Genetics of LOAD is known to involve several genetic risk factors among which the Apolipoprotein E (APOE) gene seems to be the major recognized genetic determinant. Recent efforts have been made to identify other genetic fact...
