In many polychaete species filamentous, pectinate or arborescence branchiae may be present. In species with well-developed parapodia, such as Amphinomidae and Eunicidae, they are often associated with the notopodia. Mostly they arise close to the dorsal cirrus. Whereas the branchiae are regarded as the main site for respiration, the cirri function as segmentally repeated mechanosensory and chemosensory...
A novel algorithm for multienergy X-ray radiography systems that simultaneously estimate multiple measurements with energy diversity is presented. In contrast to conventional dual source X-ray radiography which utilizes simple weighted subtractions, the proposed algorithm aims for an accurate material decomposition of more than two materials. The numerical simulation as well as the real experiment...
