this paper is devoted to the spectral theory (more precisely, tothe variational theory of the spectrum) of guided waves in anelastic half cylinder.  we use variational methods to investigateseveral aspects of propagating waves, including localization (seefigure 1), existence criteria and the formulas to find them. weapproach the problem using two complementary methods: thevariational methods fo...

introduction: the phenomenon of neglected foreign bodies is a significant cause of morbidity in soft tissue injuries and may present to dermatologists as delayed wound healing, localized cellulitis and inflammation, abscess formation, or foreign body sensation. localization and removal of neglected soft tissue foreign bodies (stfbs) is complex due to possible inflammation, indurations, granulat...

BACKGROUND Surgical resection of small pulmonary nodule is challenging via thoracoscopic procedure. We describe our experience of computed tomography (CT)-guided needle puncture localization of indeterminate pulmonary nodules prior to video-assisted thoracoscopic surgery (VATS). METHODS From January 2011 to July 2014, 78 consecutive patients underwent CT-guided marking for the localization of...

The aim of this study was to assess the clinical value of radial probe endobronchial ultrasound (RP-EBUS)-guided localization of solitary pulmonary nodules (SPNs) with the combination of ultrathin bronchoscopy and methylene blue prior to video-assisted thoracoscopic surgery (VATS). An ultrathin bronchoscope was used to localize the lesions under RP-EBUS guidance in 48 patients (18 men and 30 wo...
