background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...

A 17-year-old boy with hyperparathyroidism exhibited a large cyst in the left hemi-thorax on his chest X-ray. The cyst was identified as a hydatid cyst. He was referred for biphasic methoxy isobutyl isonitrile (MIBI) parathyroid scan. A discrete ectopic parathyroid was detected in the left upper mediastinum in addition to accumulation of the MIBI tracer in the cyst wall. Using radio-guided occu...

Non-Hermitian quasicrystal forms a unique class of matter with symmetry-breaking, localization and topological transitions induced by gain loss or nonreciprocal effects. In this work, we introduce non-Abelian generalization non-Hermitian quasicrystal, in which the interplay between effects quasiperiodic potentials create mobility edges rich among extended, critical localized phases. These gener...
