We define a 2-category whose objects are fuzzy sets and whose maps are relations subject to certain natural conditions. We enrich this category with additional monoidal and involutive structure coming from t-norms and negations on the unit interval. We develop the basic properties of this category and consider its relation to other familiar categories. A discussion is made of extending these re...

Let M be a transitive model of set theory. There is a canonical interpretation functor between the category of regular Hausdorff, continuous open images of Čech-complete spaces of M and the same category in V , preserving many concepts of topology, functional analysis, and dynamics. The functor can be further canonically extended to the category of Borel subspaces. This greatly simplifies and e...

Given a categorical crossed module H→ G, where G is a group, we show that the category of derivations, Der(G,H), from G into H has a natural monoidal structure. We introduce the Whitehead categorical group of derivations as the Picard category of Der(G,H) and then we characterize the invertible derivations, with respect to the tensor product, in this monoidal category. 2000 Mathematics Subject ...

this study investigates correlation between journal self – citation and impact factor in agriculture and veterinary subject category through the scientific journals indexed in isc's pjcr during 2001 to 2007. citation analysis is used to conduct the research. the results indicate a significant correlation between impact factor and journal self – citation (r=0.425, sig= 0.000); that is, journals ...

Fox (1994) purports to determine the appropriateness of the normative data for the Logical Memory subtest of the Wechsler Memory Scale-Revised for individuals in litigation and suggests that "...many of these people would have been incorrectly diagnosed as having a neuropsychological problem that did not exist." His data do not support such a conclusion, but rather appear simply to demonstrate ...

We used functional magnetic resonance imaging (fMRI) to investigate within-subject reproducibility of activation in higher level, category-specific visual areas to validate the functional localization approach widely used for these areas. The brain areas investigated included the extrastriate body area (EBA), which responds selectively to human bodies, the fusiform face area (FFA) and the occip...

1 olearia, illuminate its adaptation to growth from 20ºC to 79ºC 2 Abstract 1 7 Temperature is one of the defining parameters of an ecological niche, and ambient temperature change is 1 8 a physiological challenge faced by all living cells. Most organisms are adapted to growing within a 1 9 temperature range that rarely exceeds ~ 30°C, but the deep subsurface bacterium Kosmotoga olearia is 2 0 ...

We present a comparative study of certain invariants defined for group actions and their analogues orbifolds. In particular, we prove that Fadell's equivariant category $G$-spaces coincides with the Lusternik-Schnirelmann orbifolds when is finite.

The notion of proof-net category defined in this paper is closely related to graphs implicit in proof nets for the multiplicative fragment without constant propositions of linear logic. Analogous graphs occur in Kelly’s and Mac Lane’s coherence theorem for symmetric monoidal closed categories. A coherence theorem with respect to these graphs is proved for proof-net categories. Such a coherence ...
