Residual Stress Properties of the Welded Thick Underwater Spherical Pressure Hull Based on Finite Element Analysis

Residual stress inevitably occurs at the weld in the process of manufacturing thick pressure hulls for manned submersibles, which affects the bearing capacity of the hull.In this study, an electron-beam-welded 32 mm-thick Ti-6Al-4V plate specimen is first tested, then the measured data of residual stress distribution is applied to validate the accu

Early postnatal interactions between beige adipocytes and sympathetic neurites regulate innervation of subcutaneous fat

While beige adipocytes have been found to associate with dense sympathetic neurites in mouse inguinal subcutaneous white fat (iWAT), little is known about when and how this patterning is established.Here, we applied whole-tissue imaging to examine the Door Stop Bracket development of sympathetic innervation in iWAT.We found that parenchymal neurite
