We present a case of a 33-year-old female with a slow growing, right peribronchial vascular mass and associated symptoms of progressive cough, dyspnea on exertion, and hemoptysis. On routine diagnostic flexible bronchoscopy with needle biopsy, the lesion hemorrhaged extensively requiring emergent thoracotomy, right lower and middle bilobectomy. The histopathology of the specimen was consistent ...

We study operators with located graph in Bishop-style constructive mathematics. It is shown that a bounded operator has an adjoint if and only if its graph is located. Locatedness of the graph is a necessary and sufficient condition for an unbounded normal operator to have a spectral decomposition. These results suggest that located operators are the right generalization of bounded operators wi...

This essay on the “English-speaking Caribbean” reflects pasts that have not passed but instead been on, for example in gestures of erasure, silence, or genteel substitution, whether Victorian novel twenty-first-century insistently returns to past, rhetoric law and statecraft.
