The spindle assembly checkpoint (SAC) arrests mitosis until bipolar attachment of spindle microtubules to all chromosomes is accomplished. However, when spindle formation is prevented and the SAC cannot be satisfied, mammalian cells can eventually overcome the mitotic arrest while the checkpoint is still activated. We find that Aspergillus nidulans cells, which are unable to satisfy the SAC, in...

Spatial autocorrelation (SAC) is the dependence of a given variable’s values on the values of the same variable recorded at neighboring locations (Cliff and Ord 1973; Fortin and Dale 2005). When high values are associated with relatively high values at neighboring locations, SAC is said to be positive and, conversely, where high values correspond to relatively low values at neighboring location...

Background: Outbreak of bluetongue virus serotype-8 (BTV-8) infection in domestic ruminants in Northern Europe. Objective: To investigate the South American camelids’ (SAC) susceptibility to BTV-8 infection, their role in the epidemiology of the disease, and the use of currently available serological screening tests in SAC in an endemic region. Animals: Three hundred and fifty-four unvaccinated...

The female gametophyte of flowering plants, the embryo sac, develops within the diploid (sporophytic) tissue of the ovule. While embryo sac-expressed genes are known to be required at multiple stages of the fertilization process, the set of embryo sac-expressed genes has remained poorly defined. In particular, the set of genes responsible for mediating intracellular communication between the em...

in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...

Neighbourhood singleton arc consistency (NSAC) is a type of singleton arc consistency (SAC) in which the subproblem formed by variables adjacent to a variable with a singleton domain is made arc consistent. This paper describes two extensions to neighbourhood SAC. The first is a generalization from NSAC to k-NSAC, where k is the maximum length of the shortest path between the singleton variable...
