On Abrams’ theorem
Abrams’ theorem describes a necessary and sufficient condition for the closedness of a linear image of an arbitrary set. Closedness conditions of this type play an important role in the theory of duality in convex programming. In this paper we present generalizations of Abrams’ theorem, as well as Abrams-type theorems characterizing other properties (such as relatively openness or polyhedrality...
متن کاملAaron Abrams and Saul Schleimer
J. Hempel in [6] showed that the set of distances of the Heegaard splittings (S,V , hn(V)) is unbounded, as long as the stable and unstable laminations of h avoid the closure of V ⊂ PML(S). Here h is a pseudo-Anosov homeomorphism of a surface S while V is the set of isotopy classes of simple closed curves in S bounding essential disks in a fixed handlebody. With the same hypothesis we show that...
متن کاملHepatotoxicity induced by horse ATG and reversed by rabbit ATG: a case report
BACKGROUND The use of antilymphocyte agents has improved patient and graft survival in hematopoietic stem cell and solid organ transplantation but has been associated with the development of short-term toxicities as well as long-term complications. CASE PRESENTATION We report a young female with Fanconi anemia who received antithymocyte globulin as part of the conditioning regimen prior to he...
متن کاملMultiple pleural biopsy with the Abrams needle.
Multiple pleural biopsies (up to 10) were taken with the Abrams needle through a single aspiration site in 55 patients with pleural effusions. A definite positive or suggestive pleural biopsy diagnosis was made in 33 patients (60%). In 32 of the 33 patients the pathological abnormality was confined to only a proportion of the biopsies. Pleural biopsies were positive or suggestive in 26 out of 3...
متن کاملPleural biopsy with Cope and Abrams needles.
The object of this study was to compare the diagnostic yield of Abrams and Cope needles. Pleural biopsies were performed in 24 patients with both needles. In two patients, the procedure was repeated within a few days. All patients had pleural effusion. The biopsies were performed at the same time; the biopsy sites were no more than 5 cm distant from each other. Diagnoses were exclusively pathol...
