We introduce the notions of blocked, block-marked and block-deterministic regular expressions. We characterize block-deterministic regular expressions with determin-istic Glushkov block automata. The results can be viewed as a generalization of the characterization of one-unambiguous regular expressions with deterministic Glushkov automata. In addition, when a language L has a block-determinist...

It is shown that the quantum SU(3) gauge theory can be approximately reduced to U(1) gauge theory with broken gauge symmetry and interacting with scalar fields. The scalar fields are some approximations for 2 and 4-points Green’s functions of A μ gauge potential components. The remaining gauge potential component A8μ is the potential for U(1) Abelian gauge theory. It is shown that reduced field...

We have investigated micellization in systems containing two surfactant molecules with the same structure using a lattice Monte Carlo simulation method. For the binary systems containing two surfactants, we have varied the head-head interactions or tail-tail repulsions in order to mimic the nonideal behavior of mixed surfactant systems and to manipulate the net interactions between surfactant m...

This is the third of the series of the papers dealing with holonomic systems(*. A holonomic system is, by definition, a left coherent (f-Module (or ^-Modules)* whose characteristic variety is Lagrangian. It shares the finiteness theorem with a linear ordinary differential equation, namely, all the cohomology groups associated with its solution sheaf are finite dimensional ([6], [12]). Hence the...

background : cervical cancer is the second most common cancer among women in the world and the most common cancer in developing countries. pap smear is and effective tool that can prevent death due to cervical cancer . the aim of this study was to determine the factors related to doing regular pap-smear test based on the theory of planned behavior . methods : in this cross-sectional study, cond...

deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. the governing differential equations and c...

We present a procedure that transforms singular, asymptotically flat, static and spherically symmetric black hole into regular spacetime. The is solution of General Relativity theory coupled to nonlinear electrodynamics (NLED), even if the original metric not vacuum, or electro-vacuum, (GR).
