A spin-labeled derivative of rabbit muscle creatine kinase has been prepared by reaction of the essential sulfhydryl group at the active sites with a stoichiometric amount of the nitroxide radical N-( I-oxyl-2,2,5,5-tetramethyl-d-pyrrolidinyl) iodoacetamide. The spin-labeled enzyme retains the ability to bind nucleotide substrates although it lacks the phosphotransferase and ATPase activities o...

purpose :   this study was designed to compare the effects of two different relaxation techniques, namely progressive muscle relaxation (pmr) and autogenic relaxation (agr) on moods of young soccer players . methods :   sixteen adolescent athletes (mean age: 14.1 ± 1.3) received either pmr or agr training. using profile of mood states-adolescents, their mood states were measured one week before...

Decoherence induced by laser frequency noise is one of the most important obstacles in quantum information processing. In order to suppress this decoherence, power spectral density needs be accurately characterized. particular, spectrum measurement based on coherence characteristics qubits would a meaningful and still challenging method. Here, we theoretically analyze experimentally obtain cont...

Material property viscoelastic inversion studies often rely on the continuous -time framework for Fourier analysis, which may not accurately represent real experimentally collected data. In this paper, we address discrete and finite nature of functions obtained from experiments discuss impact these characteristics frequency spectrum analysis. We derive equations Discrete-Time Transform (DTFT) a...
