Consider a hypergraph $H_n^d$ where the vertices are points of $d$-dimensional combinatorial cube $n^d$ and edges all sets $n$ such that they in one line. We study structure group automorphisms $H_n^d$, i.e., permutations preserving edges. In this paper we provide complete characterization. Moreover, consider Colored Cube Isomorphism problem deciding whether for two colorings there exists an au...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

Among the most intriguing forms of Ca(2+) channel modulation is the regulation of L-type and P/Q-type channels by intracellular Ca(2+), acting via unconventional channel-calmodulin (CaM) interactions. In particular, overexpressing Ca(2+)-insensitive mutant CaM abolishes Ca(2+)-dependent modulation, hinting that Ca(2+)-free CaM may "preassociate" with these channels to enhance detection of local...

Observers can quickly search among shaded cubes for one lit from a unique direction. However, replace the cubes with similar 2-D patterns that do not appear to have a 3-D shape, and search difficulty increases. These results have challenged models of visual search and attention. We demonstrate that cube search displays differ from those with "equivalent" 2-D search items in terms of the informa...

Let Ps(d) be the probability that a random 0/1-matrix of size d× d is singular, and let E(d) be the expected number of 0/1-vectors in the linear subspace spanned by d − 1 random independent 0/1-vectors. (So E(d) is the expected number of cube vertices on a random affine hyperplane spanned by vertices of the cube.) We prove that bounds on Ps(d) are equivalent to bounds on E(d): Ps(d) =

A better understanding of the wave-induced pore pressure accumulations (i.e., residual pore pressure) is a key factor in the analysis of the wave-induced liquefaction in marine sediments. In this paper, the residual mechanism of nonlinear wave-induced pore water pressure accumulation in marine sediments is examined. Unlike previous investigations, the second-order Stokes wave theory is consider...
