Abstract Background The human foetus typically needs to rotate when passing through the tight birth canal because of the complex shape of the pelvis.In most women, the upper Car Window Nets part, or inlet, of the birth canal has a round or mediolaterally oval shape, which is considered ideal for parturition, but it is unknown why the lower part of
Recently, with the increasing adoption of synthetic aperture radar (SAR) ship detection methods on mobile platforms, the lightweighting of detection methods has become a research focus.Despite certain achievements, there are still several limitations: 1) Existing studies Turners have mainly focused on reducing model complexity through shallow netwo
Dynamic analysis of a rotor-bearing-pedestal system with multiple bearing clearances is conducted in this study.Firstly, Jones-Harris method is used to deduce the equivalent nonlinear support stiffness of angular contact high-speed ball Car Window Nets bearing with preload considered.Ignoring the structural deformation, the contact model of inner a
Abstract Ghost moths are an unusual family of primitive moths Pet Supplies (Lepidoptera: Hepialidae) known for their large body size and crepuscular adult activity.These moths represent an ancient lineage, frequently have soil dwelling larvae, and are adapted to high elevations, deserts, and other extreme environments.Despite being rather speciose
