Shock induced star formation in a stellar density wave scenario produces an azimuthal gradient of ages across the spiral arms which has opposite signs on either side of the corotation resonance (CR). We present a method based on the Fourier analysis of azimuthal profiles, to locate the CR and determine the arm character (trailing or leading) in spiral galaxies. Basically, we compare the behavio...

Aimed at sixth-generation (6G) mobile communication applications, three fifth-order novel ultra-compact hairpin bandpass filter is proposed. Through-Silicon Via (TSV), a three-dimensional integration technology, used to implement the arms of units, and some units consist four arms. In this letter, design method proposed filters introduced, filtering characteristics are verified by HFSS, an indu...

BACKGROUND Studies comparing acceleromyography and mechanomyography indicate that the two methods cannot be used interchangeably. However, it is uncertain to what extent differences in precision between the methods and the naturally occurring arm-to-arm variation have influenced the results of these studies. Accordingly, the purpose of this study was to examine the precision and the arm-to-arm ...
