We prove that any completely regular code with minimum eigenvalue in geometric graph Γ corresponds to a the clique of Γ. Studying interrelation these codes, complete characterization codes Johnson graphs J(n,w) covering radius w−1 and strength 1 is obtained. In particular this result finishes J(n,3). also classify J(n,4) only one case for eigenvalues left open.

We introduce regular charts as physical reference frames in spacetime, and we show that general spacetimes can always be fully captured by regular charts. Effective quantum field theories (QFTs) can be conveniently defined in regular reference frames, and the definition is independent of specific background metric and independent of specific regular reference frame. As a consequence, coupling t...

The objective of this review to be submitted in two independent parts, for steel frames and for RC frames, is to compare their structural performance with respect to the proposed N2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. A preliminary investigation is presented on a pushover analysis used for the seismic perf...

UNLABELLED WiGID, wireless genome information database, is a new application for mobile internet and can be reached through wireless application protocol (WAP). The main purpose of WiGID is to give easy access to information on completely sequenced genomes. Genome entries in WiGID can be queried by the number of open reading frames (ORFs), genus and species name and year published. Initial sear...

Schwarz and Weck-Schwarz have shown that a T2-ordered space (X, τ, ) whose underlying topological space (X, τ) is completely regular need not be a completely regularly ordered space (that is, T3.5 + T2-ordered T3.5-ordered). We show that a completely regular T2-ordered space need not be completely regularly ordered even under more stringent assumptions such as convexity of the topology. One exa...
