The correlation coefficient is commonly used as a measure of the divergence of gene expression profiles between different species. Here we point out a potential problem with this statistic: if measurement error is large relative to the differences in expression, the correlation coefficient will tend to show high divergence for genes that have relatively uniform levels of expression across tissu...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Research supported by NSERC, the Natural Sciences and Engineering Research Council of Canada. Some rapidly convergent formulae for special values of the Riemann zeta function are given. We obtain a generating function formula for (4n+3) that generalizes Apéry’s series for (3), and appears to give the best possible series relations of this type, at least for n< 12. The formula reduces to a finit...
We introduce a new divergence measure, the bounded Bhattacharyya distance (BBD), for quantifying the dissimilarity between probability distributions. BBD is based on the Bhattacharyya coefficient (fidelity) , and is symmetric, positive semi-definite, and bounded. Unlike the Kullback-Leibler divergence, BBD does not require probability density functions to be absolutely continuous with respect t...
Abstract. We present an involution for a classical identity on the alternate sum of the Gauss coefficients in terms of the traditional Ferrers diagram. It turns out that the refinement of our involution with restrictions on the height of Ferrers diagram implies a generalization of the Gauss identity, which is a terminating form of the q-Kummer identity. Furthermore, we extend the Gauss identity...
در این مطالعه، محیط کلریمتریک آنتی بیوگرام که در دانشگاه الزهرا طراحی گردیده است با محیط quicolor شرکت سالوبریس آمریکا و محیط مولر هینتون آگار مقایسه گردید. الگوی حساسیت صد جدایه انترو باکتریاسه با شش آنتی بیوتیک مختلف مشخص گردید. توافق هر سه روش با آنالیزکاپا بررسی گردید. با ده بار تکرار تست حساسیت آنتی بیو تیکی دو سوش استاندارد و دو جدایه بالینی از خانواده انتروباکتریاسه، در هر سه محیط مقادیر...
is a Carleson measure in a Lipschitz domain Ω ⊂ R, n ≥ 1, (here δ (X) = dist (X, ∂Ω)). If the harmonic measure dωL0 ∈ A∞, then dωL1 ∈ A∞. This is an analog to Theorem 2.17 in [8] for divergence form operators. As an application of this, a new approximation argument and known results we obtain: Let L be an elliptic operator with coefficients A and drift term b; L can be in divergence or nondiver...
