The TOPOS study

VASA. Zeitschrift fur Gefasskrankheiten
Background: We aimed to study the long-term safety and efficacy of oblique venous stents for post-thrombotic syndrome (PTS) with iliac vein compression. Patients and methods: In the multinational, prospective, single-arm TOPOS study, PTS patients scheduled for endovascular therapy with the sinus-Obliquus$^{®}$ stent and optional distal extension with ...

On comparability in a topos

Proceedings of the American Mathematical Society, 1986
While studying the category of "finite" sets associated to a nonstandard model of arithmetic [ 4 ], it became apparent that the law of trichotomy plays an important role in that context. The object of this note is to point out the strength of the obvious variants of trichotomy in a general ...

Topos Österreich | Topos Austria

2020
Karl Kraus called Austria the “testing facility for the apocalypse”, but also noted that “the streets of Vienna are paved with culture; the streets of other cities with asphalt”. Hugo von Hofmannsthal dismissed the idea that there was an Austrian form of literature as fiction.

When is a variety a topos?

Algebra Universalis, 1985
Besides categories of M-sets, where M is a monoid, the categories of Jonsson-Tarski algebras seem to be the only other known examples of varieties, which are also topoi. The (binary) Jonsson-Tarski variety was first observed to be a topos by P. Freyd. This example was generalized, first by the reviewer and then by Z. Barel.

Of Topo and Maxwell's Dream

Science, 1997
[ David E. Pulleyblank ][1] Topoisomerases are remarkable enzymes that remove knots and kinks from DNA. In this issue [ Rybenkov et al .][2] report that topoisomerase II (topo II) and the closely related topoisomerase IV (topo IV) actually drive a population of catenated, supercoiled, and knotted DNA molecules to an untangled state far from equilibrium.

Fuzziness in a topos

1998 IEEE International Conference on Fuzzy Systems Proceedings. IEEE World Congress on Computational Intelligence (Cat. No.98CH36228), 2002
Elementary topos can be seen as a categorical axiomatization of the classical set theory. They are basically categories in which each subobject can be uniquely described by reference to a subobject (named "true") of a distinguished object, the subobject classifier.
