The genetic relationship of American plains bison (Bison bison bison) and wood bison (Bison bison athabascae) was quantified and compared with that among breeds and subspecies of cattle. Plains bison from 9 herds (N = 136), wood bison from 3 herds (N = 65), taurine cattle (Bos taurus taurus) from 14 breeds (N = 244), and indicine cattle (Bos taurus indicus) from 2 breeds (N = 53) were genotyped...

disasters provide physical, social, political and environmental development windows of opportunities that can be used not only to reconstruct the impacted areas, but also to improve the socio-economic and physical conditions of the impacted population in the long run. it is argued, however, that there is a limited time frame of approximately four years for such opportunities to be utilized effi...

Escherichia coli is one of the predominant species of facultative anaerobes in the human gut and usually harmless to the host; however, a group of pathogenic E. coli has emerged that causes diarrheal disease in humans. Referred to as Diarrheagenic E. coli (28) or commonly as pathogenic E. coli, these groups are classified based on their unique virulence factors and can only be identified by the...

In the synchronous discrete model, the average memory capacity of bidirectional associative memories (BAMs) is compared with that of Hopfield memories, by means of a calculat10n of the percentage of good recall for 100 random BAMs of dimension 64x64, for different numbers of stored vectors. The memory capac1ty Is found to be much smal1er than the Kosko upper bound, which Is the lesser of the tw...

This paper gives a brief explanation of the earthquake in Bam. It also reports on the rescue and relief operations, including the construction of emergency shelters and temporary housing, and on the country’s plan for the reconstruction of the city, which includes debris removal, the rebuilding of rural and urban residential and commercial units, the reconstruction of state and public buildings...

In contrast to conventional feedback bidirectional associative Memory (BAM) network models, a feedforward BAM network is developed based on a one-shot design algorithm of O(p(2)(n+m)) computational complexity, where p is the number of prototype pairs and n, m are the dimensions of the input/output bipolar vectors. The feedforward BAM is an n-p-m three-layer network of McCulloch-Pitts neurons wi...

Autotransporters are a superfamily of bacterial virulence factors consisting of an N-terminal extracellular ('passenger') domain and a C-terminal β barrel ('β') domain that resides in the outer membrane (OM). The mechanism by which the passenger domain is secreted is poorly understood. Here we show that a conserved OM protein insertase (the Bam complex) and a molecular chaperone (SurA) are both...

This is a study of paradigmatic relations and of their significance for the link between phonology and phonetics *. A paradigm is a set of words sharing a morpheme of phrases sharing a word (e.g.{bomb, the bomb, ...}). The main component of the analyses presented here is the preference for uniform paradigms, that is paradigms sharing contextually invariant morphemes. A Paradigm Uniformity (PU) ...

Bidirectional Associative Memories (BAMs) are artificial neural networks that can learn and recall various types of associations. Although BAMs have shown great promise at modeling human cognitive processes, these models have often been investigated under optimal conditions in which the network is fully connected. Whereas some BAM models have shown to be robust to connection sparseness, those p...
