Abstract We present a strong-lensing analysis of the cluster PSZ1 G311.65?18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core ( z = 0.443) lenses brightest lensed galaxy known, dubbed “Sunburst Arc” 2.3703), Lyman continuum (LyC) emitting multiply imaged 12 times. identify in this field 14 additional strongly galaxies to constra...

Intraosseous hemangioma is a rare bone tumor accounting for 0.7%-1.0% of all bone tumors. In the skull, frontal bone is the commonly involved bone. An 8-year-old female presented to our outpatient department with complaints of pain and swelling over forehead for 4 months. X-ray revealed a lytic expansile lesion involving frontal bone with sunburst pattern of bony spicules radiating to periphery...

This paper presents an approach to browse collections of web pages about music artists by means of descriptive terms and multimedia content. To this end, a user interface called Three-Dimensional CoOccurrence Browser (3D-COB) is introduced. 3D-COB automatically extracts and weights terms from artist-related web pages. This textual information is complemented with information on the multimedia c...

Intraosseous vascular lesions of the maxillofacial region are rare, and the differential diagnosis of intraosseous vascular malformations from other jaw lesions can be challenging. In the present case, magnetic resonance imaging and three-dimensional computed tomographic angiography (CTA) was used for diagnosis, and the lesion was treated wih surgical excision. Diverse characteristics such as t...

OBJECTIVES To categorize the radiological presentation of osteosarcoma of the jaws. METHODS Conventional radiographs and CT scans of nine patients with histologically proven osteosarcoma were reviewed. RESULTS Five patients were men and four women, aged between 20 and 51; four lesions were in the maxilla and five in the mandible. Three radiological presentations of osteosarcoma of the jaw w...

Osteosarcoma (OS) is a highly malignant bone forming tumor characterized by frankly to subtly anaplastic stromal cells with evidence of direct formation of osteoid and/or primitive bone by these cells. Incidence is lower in jaws as compared to long bones (4-13%). They have different biological behaviour but same histopathology. The mean age of occurrence is third to fourth decade, almost a deca...

Sequent calculus is widely used for formalizing proofs. However, due to the proliferation of data, understanding the proofs of even simple mathematical arguments soon becomes impossible. Graphical user interfaces help in this matter, but since they normally utilize Gentzen’s original notation, some of the problems persist. In this paper, we introduce a number of criteria for proof visualization...
