in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...

PURPOSE The purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome. METHODS Approval from the Institutional Review Board was obtained. A retrospective review of 908 patients' sonographic images of the upper extremity from January 2001 to October 2010 revealed 10 patients suspicious for a PIN abnormality (7 male and 3 fem...

Odd-dimensional Riemannian spaces that are non-orientable, but have a pin structure, require the consideration of the twisted adjoint representation of the corresponding pin group. It is shown here how the Dirac operator should be modiied, also on even-dimensional spaces, to make it equivariant with respect to the action of that group when the twisted adjoint representation is used in the deeni...

We introduce quantum pin codes: a class of CSS codes. Quantum codes are generalization color and Reed-Muller share lot their structure properties. Pin have gauge operators, an unfolding procedure stabilizers form so-called $\ell $ -or...

Problems occurring in the use of external fixators for bone fractures include pin-bone interface necrosis, infection, and loosening. These may be initiated and enhanced by pin-bone interface stress levels. Based on stress data from finite element method (FEM) models, an analytical "closed-form" model of the local pin-bone configuration in long-bone fracture fixation is developed. This model is ...
