We present a new experimental system of monodisperse, soft, frictionless, fluorescent labeled elastic shells for the characterization of structure, universal scaling laws and force networks in 3D jammed matter. The elastic shells in a jammed packing are deformed in such a way that at each contact one of the shells buckles with a dimple and the other remain spherical, closely resembling overlapp...

INTRODUCTION To improve the fracture resistance of nickel-titanium (NiTi) files, manufacturers have introduced new alloys to manufacture NiTi files and developed new manufacturing processes. This study was aimed to examine the fatigue behavior of NiTi instruments from a novel controlled memory NiTi wire (CM Wire). METHODS Instruments of ProFile, Typhoon (TYP), Typhoon CM (TYP CM), DS-SS025042...

The influence of the ratio dimple depth-to-print diameter (λ) on highly loaded compressor cascade NACA0065-K48 is investigated based Reynolds-averaged Navier–Stokes (RANS) method. Simulations are conducted with a validated shear-stress transportation (SST) turbulence model coupled Gamma-Theta (γ−Reθ) transition at inlet Mach number 0.7. At 5~25% axial chord suction surface, four rows dimples ar...
