We demonstrate the existence of a new approximate ambiguity in structure from motion which occurs as generically as the bas{relief ambiguity but applies more strongly to scenes with larger depth variation. It occurs for moderate translations and eld of view (as for the bas{relief ambiguity) and applies to multi{frame, nite{motion sequences where the camera moves roughly along a line, as well as...

Labour has long been recognized as a very painful event. Efforts have therefore been made over the years, particularly in the developed world, to relief pain in labour. Unfortunately the same attention has not been given to obstetric analgesia in Africa because of the belief that Africans cope well with labour pains. However a recent study among Nigerian women have shown that most African women...

Chronic abdominal wall pain is a well-documented complication of abdominal surgery. However, abdominal wall complex regional pain syndrome (CRPS) is a rare medical condition. We present a case of abdominal wall CRPS and its treatment with peripheral nerve field stimulation (PNfS). A 34-year-old female presented with right periumbilical pain for 2 years. She developed burning, sharp and stabbing...

Image intensity variations can result from several different object surface effects, including shading from 3-dimensional relief of the object, or paint on the surface itself. An essential problem in vision , which people solve naturally, is to attribute the proper physical cause, e.g. surface relief or paint, to an observed image. We addressed this problem with an approach combining psychophys...

Buprenorphine-naloxone (bup/nal in 4:1 ratio; Suboxone®, Reckitt Benckiser Pharmaceuticals Incorporation, Richmond, VA) is approved by the Food and Drug Administration for outpatient office-based addiction treatment. In the past few years, bup/nal has been increasingly prescribed off-label for chronic pain management. The current data suggests that bup/nal may provide pain relief in chronic pai...

History has shown that local, state, and federal governments are not well-equipped with the flexible and responsive abilities necessary to manage the short supply chain life-cycle inherent in providing appropriate disaster relief resources in a timely fashion. Unfortunately, in these unique situations these inefficiencies can cause considerable harm to the citizenry, the financial economy, and ...

A virtual haptic-audio drawing program prototype designed for visuallyimpaired children has been gradually developed in a design-evaluation loop involvingusers in four stages. Three qualitative evaluations focused on recognizing drawnshapes and creating drawings have been conducted together with a reference group of5 visually impaired children. Additionally, one formal pilot tes...

Image-Based Rendering by Warping (IBRW) creates three-dimensional scene by deforming several 2D images with depth information. Image-based rendering has an advantage compared to traditional polygon rendering that the rendering time is still constant even if a scene becomes complex. Relief texture mapping decomposes IBRW into a very simple 1D image operation and a traditional texture mapping, wh...

INTRODUCTION Magnetic stimulation of the sacral nerve roots is used for neurologic examination. However, no one has reported therapeutic efficacy of pain relief from pudendal neuralgia with sacral magnetic stimulation. METHODS Five patients with pudendal neuralgia or sciatica received 30 to 50 pulsed magnetic stimuli of the sacral nerve roots. The median age of the patients was 59 (range, 28-...
