Neuromedins are a family of peptides best known for their contractile activity on smooth muscle preparations. The biological mechanism of action of neuromedin U remains unknown, despite the fact that… (More)

We give a method to construct cospectral graphs for the normalized Laplacian by swapping edges between vertices in some special graphs. We also give a method to construct an arbitrarily large family… (More)

We will consider two parameters which can be associated with a nonnegative matrix: the second largest singular value of the “normalized” matrix, and the discrepancy of the entries (which is a… (More)

Hat problems have become a popular topic in recreational mathematics. In a typical hat problem, each of n players tries to guess the color of the hat they are wearing by looking at the colors of the… (More)

For a family F of graphs, a graph U is induced-universal for F if every graph in F is an induced subgraph of U . We give a construction for an induced-universal graph for the family of graphs on n… (More)

Given fixed 0 = q0 < q1 < q2 < · · · < qk = 1 a constellation in [n] is a scaled translated realization of the qi with all elements in [n], i.e., p, p + q1d, p + q2d, . . . , p + qk−1d, p + d. We… (More)

The circuit techniques used to implement a 600MHz, out-of-order, superscalar RISC Alpha microprocessor are described. Innovative logic and circuit design created a chip that attains 30+ SpecInt95 and… (More)

We consider the problem of orienting the edges of the n-dimensional hypercube so only two different in-degrees a and b occur. We show that this can be done, for two specified in-degrees, if and only… (More)

In this paper, we examine the tilings of a 2 × n “triangular strip” with triangles. These tilings have connections with Fibonacci numbers, Pell numbers, and other known sequences. We will derive… (More)
