The quality of the image formed by an optical system is reduced by aberrations. This paper points out and attempts to correct blindness of lens aberration. Therefore modified Zernike moments were introduced to present lens aberration model within which their coefficients were estimated through poly-spectral analysis. The model parameters are divided into asymmetric and symmetric which are estim...
Stem cells have the remarkable ability to undergo proliferative symmetric divisions and self-renewing asymmetric divisions. Balancing of the two modes of division sustains tissue morphogenesis and homeostasis. Asymmetric divisions of Drosophila neuroblasts (NBs) and sensory organ precursor (SOP) cells served as prototypes to learn what we consider now principles of asymmetric mitoses. They also...
We propose to study hadron-hadron scattering using lattice QCD in an asymmetric box which allows one to access more non-degenerate low-momentum modes for a given volume. The conventional Lüscher’s formula applicable in a symmetric box is modified accordingly. To illustrate the feasibility of this approach, pion-pion elastic scattering phase shifts in the I = 2, J = 0 channel are calculated with...

In Letter [1], we reported our finding on the physical origin of wide band-gap opening in planar nanostrips, as derived by application of periodic width modulations in the magnetic waveguides. K. Di et al. in their Comment[2], however, argued that the band gap can be reduced remarkably by applying a linear combination of symmetric and antisymmetric fields (see 'A+B' in the inset of Fig. 1(a)). ...

Background: To define the dynamic organization of the neuromuscular system, we need useful tools that allow for the expression of the neuromuscular system in low dimensional term (i.e one variable), so it seems that relative phase provides a better measure of organization of the neuromuscular system. Besides, selection of a measure for research or clinical use should be motivated by several f...
in this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. this paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (st) decomposition. by this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix s and a fuzzy triangular matrix t.
