The conformational properties of the atrial natriuretic peptide atriopeptin III were investigated by Fourier-transform infrared spectroscopy. Infrared spectra in the amide I region were analyzed quantitatively using deconvolution and band-fitting procedures. According to this analysis, in aqueous solution the monomeric peptide has a random structure. Binding to bilayer vesicles of dimyristoyl p...

The basic principle of photogrammetry is mature and widely used in engineering. For gantry cranes, the base which usually a cylinder, measurement center cylinder cross section difficult, but its coordinates have an important impact on safety evaluation cranes. Aiming at problem measuring circle, optimization method fitting circle based Hough transform proposed. In this algorithm, effect image p...

The micro-Doppler features formed by the micro-motion of rotating blades rotors and turbines are great significance for aircraft target detection recognition. Mastering is premise radar identification. blades’ length rotation rate vital parameters classifying targets. One can instantly judge type state targets extracting features. To extract turbine target, we utilized microwave-band terahertz-...
