Topological transitions in core-annular ow of oil and water are described. Drops of one liquid are suspended in the second liquid and transported through a pipeline under a pressure gradient. We examine the merging of an array of drops in this twouid ow. Larger drops are found to merge and the ow undergoes a topological transition to core-annular ow. In core-annular ow of two liquids, one liqui...
STUDY DESIGN Systematic review and meta-analysis of comparative studies. OBJECTIVE To characterize the association of annular defect width after lumbar discectomy with the risk of symptom recurrence and reoperation. SUMMARY OF BACKGROUND DATA Large annular defect width after lumbar discectomy has been reported to increase risk of symptom recurrence. However, this association has not been ev...
We report the observation of plasmonic modes of annular resonators in nanofabricated Ag and Au surfaces that are imaged by spectrally resolved cathodoluminescence. A highly focused 30 keV electron beam is used to excite localized surface plasmons that couple to collective resonant modes of the nanoresonators. We demonstrate unprecedented resolution of plasmonic mode excitation and by combining ...
Eosinophilic annular erythema is a rare, benign, recurrent disease, clinically characterized by persistent, annular, erythematous lesions, revealing histopathologically perivascular infiltrates with abundant eosinophils. This report describes an unusual case of eosinophilic annular erythema in a 3-year-old female, requiring sustained doses of hydroxychloroquine to be adequately controlled.
Annular pancreas can present in adult life, usually when inflammation of the pancreatic ring causes duodenal stenosis. Although peptic ulcer is often associated with annular pancreas, an association with gastric carcinoma has not been previously described. Here we report a patient with annular pancreas, chronic alcoholic pancreatitis and gastric carcinoma, who was successfully treated by radica...
Annular subvalvular left ventricular aneurysm was first reported in 1962. This type of aneurysm usually arises from the annular subaortic or submitral region of the left ventricle. It should be differentiated from the left ventricular false aneurysm, which was caused by myocardial necrosis. The etiology of subvalvular aneurysm remains unclear. We have presented a case of annular submitral left ...
