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 ...

In a recent meeting, RM Needham mentioned a Personal Identification Number (PIN) management scheme for bank’s cash dispenser transactions, which provides enhanced privacy and responsibility separation. This scheme was described as a brief example that supports his idea on security research under the changing computing environment. In this memo, we suggest a practical PIN management scheme based...

Angiogenin (ANG), originally identified as an angiogenic ribonuclease, has recently been shown to play a direct role in prostate cancer cell proliferation by mediating rRNA transcription. ANG is up-regulated in human prostate cancer and is the most significantly up-regulated gene in AKT-driven prostate intraepithelial neoplasia (PIN) in mice. Enhanced cell proliferation in the PIN lesions requi...
