To probe into the performance of concrete-filled double-skin elliptical steel tubular (CFDEST) members, this paper designs and conducts an experiment on CFDEST short columns imposed with axial pressure, and finite element (FE) models of the axially compressed CFDEST stub columns are established and verified by the test outcomes, taking the influenc
Ichthyodectiform fishes are an exclusively extinct basal teleost clade, with a temporal range from the Middle Jurassic (Bathonian) to Upper Cretaceous (Maastrichtian).The fish fossils here described were found from Maeshima islet in Kumamoto, Kyushu, Japan in an outcrop of the Hinoshima Formation of the Lower Cord/cordless lithium-ion clipper Subgr
