BACKGROUND/AIMS Most pesticide formulations contain both chief and additive ingredients. But, the additives may not have been tested as thoroughly as the chief ingredients. The surfactant, nonyl phenoxypolyethoxylethanol (NP40), is an additive frequently present in pesticide formulations. We investigated the effects of NP40 and other constituents of a validamycin pesticide formulation on cell v...

For a category $${\textsf{B}}$$ with finite products, we first characterize pseudofunctors from to $$\mathbb {C}\textsf{at}$$ whose associated opfibration is Cartesian monoidal. Among those, then the ones which extend internal groups 2-groups. If additive, this case precisely when has groupoidal fibres.

Using the tools of category theory and diierential geometry, we extend the geometric notions consequent of Gaussian detection problems to non-Gaussian ones. The nominal probability measures associated with the hypotheses in a binary detection problem form points on an innnite dimensional manifold. These measures may correspond to non-additive as well as additive noise situations and can express...

‎This paper develops a basic theory of $H$-groups‎. ‎We‎ ‎introduce a special quotient of $H$-groups and‎ ‎extend some algebraic constructions of topological groups to the category‎ ‎of H-groups and H-maps and then present a functor from this category to the category of quasitopological groups‎.

This is an introductory survey on cluster algebras and their (additive) categorification using derived categories of Ginzburg algebras. After a gentle introduction to cluster combinatorics, we review important examples of coordinate rings admitting a cluster algebra structure. We then present the general definition of a cluster algebra and describe the interplay between cluster variables, coeff...

Using an auditory semantic priming paradigm, Moss, Ostrin, Tyler and Marslen-Wilson (1995, Experiment 2) demonstrated facilitation for category coordinates and functionally-related stimuli both with and without the additive effect of normative association strength. In this paper we replicate these results computationally using a corpus-derived Contextual Similarity measure. In Experiment 1 we c...

in addition to exploring constructions and properties of limits and colimits in categories of topologicalalgebras, we study special subcategories of topological algebras and their properties. in particular, undercertain conditions, reflective subcategories when paired with topological structures give rise to reflectivesubcategories and epireflective subcategories give rise to epireflective subc...

these are notes from introductory survey lectures given at the institute for studies in theoretical physics and mathematics (ipm), teheran, in 2008 and 2010. we present the definition and the fundamental properties of fomin-zelevinsky’s cluster algebras. then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generators of ...

This paper presents a basic database for the joint actions of 44 binary mixtures of various organic toxicants on Escherichia coli. The multiple toxicity behaviors observed from the E. coli organisms were analyzed and compared with previous works based on the Microtox tests. The two kinds of tests produced quite different responses, in terms of the joint action mode and the sum of toxic units, t...
