We construct Adams operations on higher algebraic K-groups induced by operations such as symmetric powers on any suitable exact category, by constructing an explicit map of spaces, combinatorially defined. The map uses the S-construction of Waldhausen, and deloops (once) earlier constructions of the map.

It is the lack of a common, transdisciplinary language and a metaphorical map encompassing the existing major systems that constrains progress on evolutionary theory. A modification of Eldredge and Gould`s model of "punctuated equilibria" can create such a map. This map should highlight a universal sequence for organizational change processes within and among systems. If this map combines this ...

We provide a new property, called Non-Type-Preserving, for a mixing layer which guarantees protection against algebraic attacks based on the imprimitivity of the group generated by the round functions. Our main result is to present necessary and sufficient conditions on the structure of the binary matrix associated to the mixing layer, so that it has this property. Then we show how several fami...

1. Extended Abstract This talk will describe a general framework which has been established after several years of work within which it is possible to show that the solution of a general uniication problem may be viewed as that of calculating the intersection of a certain family of aane varieties ((6]). In this way, the usual realm, in which the problem of symbolic expression uniication is form...

It is shown that every map on the torus satisfying the obvious necessary conditions has a straight-line representation on the flat torus R2/Z 2. The same holds for the Klein bottle, and the two-bordered flat surfaces the cylinder and the M6bius band. I . Stra ightl ine m a p s By a well-known result of Wagner [13] (usually attributed to Ffiry [4]), every simple plane graph admits a straight-lin...

Five high-molecular-weight microtubule-associated proteins (MAPs) were identified in brain tissue in previous work from this laboratory (Bloom et al., 1984). These proteins were termed MAP 1A, 1B, 1C, 2A, and 2B. The MAP 1's differed from the MAP 2's, and showed little evidence of interrelationship on the basis of immunological and biochemical comparison. We report here that MAP 1A and MAP 1B a...

| In this paper, we describe the design and implementation of a scientiic database for the map assembly tasks performed by the geneticists at the University of Michigan Human Genome Center. Our system managescomplex genomicdata and supportsthe automationof the associatedmap assembly tasks. For this purpose, we have developed an overlap reenement hierarchy characterizing the types of overlap and...

Advanced Encryption Standard (AES) algorithm is considered as a secured algorithm. Still, some security issues lie in the S-Box and the key used. In this paper, we have tried to give focus on the security of the key used. Here, the proposed modified algorithms for the AES have been simulated and tested with different chaotic variations such as 1-D logistic chaos equation, cross chaos equation a...

High-density linkage maps are valuable tools for conservation and eco-evolutionary issues. In salmonids, a complex rediploidization process consecutive to an ancient whole genome duplication event makes linkage maps of prime importance for investigating the evolutionary history of chromosome rearrangements. Here, we developed a high-density consensus linkage map for the brown trout (Salmo trutt...

Informally speaking, a map is stratified if it is proper and there is a partition S of X into manifolds so that over each manifold S ∈ S the map f(S)→ S is a fiber bundle. One perspective on this question uses the open sets of X to define a functor F̂ : Open(X)→ Set that assigns to each open U the set π0(f (U)) of path components. This functor satisfies a gluing axiom reminiscent of the usual va...
