Bounds for entries of matrix functions based on Gauss-type quadrature rules are applied to adjacency matrices associated with graphs. This technique allows to develop inexpensive and accurate upper and lower bounds for certain quantiti...

Unramified coverings of the affine line in characteristic two are constructed having alternating groups as Galois groups. The proof uses Jacobson's criterion for the Galois group of an equation to be contained in the alternating group. ...

The neutron total cross-section of samples of uranium-233 has been measured from 0·0015 eV to 11 eV. The cross-section of U-233 at 0·0253 eV was found to be (590 ± 15) barns, and peaks were observed at 1·78 eV, 2·27 eV, 3·7 eV, 4...

From a study of ultrasonic velocity Air Jordan High Heel Black White in, and density and heat capacity of the pure components and their equimolar mixture, the excess molar heat capacity and excess isothermal compressibility of the syste...

Let C denote a crumpled n-cube in the n-sphere Sn such that every Cantor set in its boundary is tamely embedded in Sn. The main theorem shows C to be universal in the sense that however it is sewn to a crumpled n-cube D of type 2A, a l...

Results are presented showing how the specific area of grain boundaries changes during plastic straining for an initial structure comprised of random equi-axed grains. These calculations for homogeneous strain are also compared with het...

At a meeting on Matrix Theory and its Applications in Dublin in October of 1980, organized by the Irish Mathematical Society, two participants browsing in a bookstore discovered by chance the existence of a castle named Castle Matrix. I...

A new needle holder is described that has jaws metallurgically bonded with tungsten carbide particles that enhance needle holding security without causing sutural damage during instrument ties. Scissors have also been incorporated into...

A graph-theoretical approach to the problem of optimizing the sequence of plot commands is presented. The mesh to be drawn is described by a graph which is extended to an Euler graph. In the extended graph an Euler tour is found, which...

For any positive integer ss, a [2,2s][2,2s]-factor in a graph GG is a connected even factor with maximum degree at most 2s2s. We prove that if every induced S(K1,2s+1)S(K1,2s+1) in a graph GG has at least three edges in a block of degre...
