– Conformal field theory predicts finite-size scaling amplitudes of correlation lengths universally related to critical exponents on sphere-like, semi-finite systems S×R of arbitrary dimensionality d. Numerical studies have up to now been unable to validate this result due to the intricacies of lattice discretisation of such curved spaces. We present a cluster-update Monte Carlo study of the Is...

We consider the effective motion along a cylinder of a particle that freely diffuses in the bulk and intermittently binds to the cylinder. From an exact approach we derive the different regimes of the effective motion along the cylinder characterized by physical rates for binding/unbinding and the bulk diffusivity. We obtain a transient regime of superdiffusion and, interestingly, a saturation ...

We analyze the magnetic mode structure of axially magnetized finite-length nanoscopic cylinders in a regime where exchange interaction dominates, along with simulations frequencies ferrimagnet yttrium iron garnet. For bulk modes, we find that can be represented by an expression given Herring and Kittel using wavevector components obtained fitting patterns emerging from these simulations. In add...

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...

Loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. One of the most important durability problems in diesel engines is due to the cracks valves bridge area. The purpose of this study is a thermo-mechanical analysis of cylinder heads of diesel engines using a two-layer viscoplasticity model. The results of the thermo-mechani...

Introduction: The inflatable penile prosthesis (IPP) has been used to treat erectile dysfunction for 40 years. Loss of penile length following IPP remains the single biggest patient complaint. We describe a preoperative and postoperative patient preparation protocol to assist in setting realistic patient expectations and decreasing the complaint of reduced penile length. Materials & Methods: 75...
