The role of quadratic on-site pinning potentials on determining the size (N) dependence of the disorder averaged steady state heat current J in an isotopically disordered harmonic chain connected to stochastic heat baths is investigated. For two models of heat baths, namely white noise baths and Rubin's model of baths, we find that the N dependence of J is the same and depends on the number of ...

Patients with stable slipped capital femoral epiphysis (SCFE) usually can ambulate at the time of diagnosis. Satisfactory results have been reported after percutaneous in situ pinning using a fracture table. The authors describe a technique to determine the skin-pin entry point for percutaneous pinning of the hip on a regular radiolucent operating table. The pin entry point determined by this m...

We discuss flux pinning and nanostructural analyzes of two intermetallic superconductors that exhibit substantial deviations from the usual flux-shear behavior. Kramer plots for a MgB 2 thin film, which contained a substantial fraction of MgO nanoprecipitates, show an additional component that is attributed to core pinning by the precipitates. Also, polycrystalline MgCNi 3 displays a crossover ...

We study traveling waves for reaction diffusion equations on the spatially discrete domain Z2. The phenomenon of crystallographic pinning occurs when traveling waves become pinned in certain directions despite moving with non-zero wave speed in nearby directions. In [1] it was shown that crystallographic pinning occurs for all rational directions, so long as the nonlinearity is close to the saw...

Percutaneous pinning after closed reduction is commonly used to treat supracondylar fractures of the humerus in children. Minor pin tract infections frequently occur. The aim of this study was to prevent pin tract infections using a rubber stopper to reduce irritation of the skin against the Kirschner (K) wire following percutaneous pinning. Between July 2011 and June 2012, seventeen children w...

BACKGROUND Throwing athletes risk medial elbow injury from extreme valgus stress generated across the medial elbow during throwing. Braces have been developed to protect the elbow joint; however, no previous study has investigated the effects of elbow bracing on medial elbow joint space gapping associated with repetitive throwing. HYPOTHESIS/PURPOSE The purpose of this study was to investigat...

AIM To evaluate the feasibility of C-arm guided closed intramedullary pinning (simple Steinmann and end threaded) techniques for the stabilization of various canine long bone fractures. MATERIALS AND METHODS The present study was conducted on 19 dogs with long bone fractures which were stabilized using simple Steinmann (Group I; n=6) and end threaded (Group II; n=13) pinning under C-arm guida...

– We demonstrate the possibility to reliably image vortices in superconducting Nb films with a low-temperature magnetic-force microscope. Our force microscope enables to monitor the surface topography as well, allowing to correlate the location of the vortices with specific topographic features. For Nb films of different thickness (32 nm–87 nm) and different Tc (7.9 K–9.1 K) we studied how the ...

Pinning control techniques have been effectively applied for the synchronization of complex networks. In this work we proposed two different hybrid pinning control strategies that guarantee not only the synchronization of the entire network but the synchronization onto a known desired solution.
