primitive neuroectodermal tumor (penets) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. in more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). immunohistochemical staining may be required for diagnosis of penet. the cells of tumor express cd99, vimentin, nse, fl1 but do not express ck, lca, myogenin, and wt1. w...

Alex Sarch’s recent book, Criminally Ignorant: Why the Law Pretends We Know What Don’t is a wonderfully rich work.1 Sarch provides and defends an explanatorily powerful theory of criminal culpab...

To commit credibly in bargaining is crucial: In the ultimatum game with its one– sided early commitment power the “proposer” gets (nearly) the whole pie while the “responder” is left with (almost) nothing. When both parties commit simultaneously the (a)symmetric Nash(1950)–bargaining solution, however, predicts (more or less) equal shares. Relying on a continuous connection of these two games b...

We analyze how voter ignorance effects competing candidates’ policy choices and election outcomes. We show that voter ignorance of policy positions has no effect in large elections provided voters know the preference distribution in the electorate. We then explore a model where voters are ignorant of policy positions and of the preference distribution. In that case limit equilibria (as the numb...

In this paper we find sufficient conditions on primitive inverse topological semigroup S under which: the inversion inv : (H(S)) (H(S)) is continuous; we show that every topologically periodic countable compact primitive inverse topological semigroups with closed H-classes is topologically isomorphic to an orthogonal sum P i2= Bi (Gi) of topological Brandt extensions Bi (Gi) of countably compac...

The classical Gibbs paradox concerns the entropy change upon mixing two gases. Whether an observer assigns increase to process depends on their ability distinguish A resolution is that "ignorant" observer, who cannot gases, has no way of extracting work by them. Moving thought experiment into quantum realm, we reveal new and surprising behaviour: ignorant can extract from different even if gase...

this is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. histopathologically, small round blue cell tumor was diagnosed. immunoh...
