NAD(P)H dehydrogenase quinone 2 (NQO2) is a quinone reductase whose functions include the reduction of both oxidative stress during the redox cycle and neurotoxicity caused by the metabolism of catecholamines. We have investigated a functional non-synonymous exon 3 single nucleotide polymorphism (rs1143684) within the NQO2 gene for association with(More)
The propagation of steady plane shock waves in metallic materials is considered. Following the constitutive framework adopted by R. for analyzing elastic–plastic transient waves, an analytical solution of the steady state propagation of plastic shocks is proposed. The problem is formulated in a Lagrangian setting appropriate for large deformations. The(More)

This paper describes a new technique for fabrication of nondestructive inspection (NDI) standards with real cracks. This includes cracks in holes, on curved surfaces, on shot peened surfaces, in and under coatings and at buried surfaces. The method uses permanently mounted MWM ®-Array eddy current sensors to detect crack initiation and monitor crack growth.(More)
Multiplying memory span by mental speed, we obtain the information entropy of short-term memory capacity, which is rate-limiting for cognitive functions and corresponds with EEG power spectral density. The number of EEG harmonics (n = 1, 2,..., 9) is identical with memory span, and the eigenvalues of the EEG impulse response are represented by the(More)
Multiplying memory span by mental speed, we obtain the information entropy of short-term memory capacity, which is rate-limiting for cognitive functions and corresponds with EEG power spectral density. From psychometric and EEG data follows a fundamental of about 3.14 Hz. The number of harmonics (n = 1, 2,...,9) is identical with memory span, and the(More)
Late auditory evoked potentials (50-500 msec latency) can be evoked by tonal stimuli but their instability prevents their use in many clinical situations. In contrast, the early responses (up to 10 msec) are stable, regardless of sleep or sedation, but they can only be evoked by transient, non-tonal stimuli. Therefore neither type may be used for an(More)
An analogy exists between the mathematical models of psychological test theory and quantitative genetics. From this analogy we can conclude, that longitudinal correlation and heritability in the broad sense are equivalent expressions for the reliability in the long run. Since long-range prediction is the aim of index construction for personnel selection in(More)
An analogy exists between the mathematical models of psychological test theory and quantitative genetics, as well as between the parameters, reliability and heritability, derived from these models. With the same results, heritability and correlation in longitudinal studies are only different approaches to the same problem, the reliability of measurement in(More)
