We study the behavior of the longitudinal components of strongly focused electromagnetic fields. These components possess phase singularities and phase saddles that can be annihilated when the aperture angle of the lens is changed.
abstract: literature is said beautiful words of poetry or prose that excites reader’s or listener’s feel. certainly, to be effective, such a text should have certain characteristics. the four elements of the literature: thought, imagination, emotion and style make a text to be literary and effective. emotion and imagination are specific elements of literary texts, while thought and style a...
When one expands a Schur function in terms of the irreducible characters of the symplectic (or orthogonal) group, the coefficient of the trivial character is 0 unless the indexing partition has an appropriate form. A number of q-analogues of this fact were conjectured in [8]; the present paper proves most of those conjectures, as well as some new identities suggested by the proof technique. The...
The influence of dislocations on nitrogen±oxygen (N±O) complexes in nitrogen-doped Czochralski (NCZ) silicon was investigated. It was found that N±O complexes were generated during annealing at 650 C for 10 min. In the early stage of annealing the amount of the N±O complexes in NCZ silicon with dislocations was almost the same as in dislocation-free NCZ silicon. However, the N±O complexes in NC...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
This paper presents a new explanation of the width gamma-ray spectra based on Rahm's electronegativity scale. quantitatively proves, for first time, that positrophilic electrons in positron-electron annihilation process are exactly valence electrons. suggests replacement Full Width at Half Maximum (FWHM) with newly defined physical quantity Average Doppler Shift (ADS). Both FWHM and ADS light e...
Optical vortices are always created or annihilated as vortex dipoles-pairs with opposite topological charge. Here a quantity, consisting of the transverse first and second derivatives of the optical field, is derived with which one can distinguish between vortex dipole annihilation and creation events. Analytical and numerical examples are provided as a demonstration of the method.
A finitely generated $R$-module is said to be a module of type ($F_r$) if its $(r-1)$-th Fitting ideal is the zero ideal and its $r$-th Fitting ideal is a regular ideal. Let $R$ be a commutative ring and $N$ be a submodule of $R^n$ which is generated by columns of a matrix $A=(a_{ij})$ with $a_{ij}in R$ for all $1leq ileq n$, $jin Lambda$, where $Lambda $ is a (possibly infinite) index set. ...
