Comparison between the various impact factors of a few Russian journals demonstrates the deficiencies of the popular citation indices. DOI: 10.1134/S1990478909030065 Since recently there has been much ado invoked in science by incessant attempts at replacing expertise with numerical manipulations. Of especial relevance to the Russian mathematical community are the following indices: • MCQ, the ...

Background: Job-related allergic contact dermatitis (ACD) mayprolong the disease duration, increase disabilities, and decreasethe patient’s quality of life. The aim of this study was to determinecommon allergens causing ACD, investigating certain featuresof the disease and evaluating its relation to the patients’ jobs.Method: In this cross-sectional study, relevant data was obtainedfrom patch t...

A vertex irregular total k-labeling of a graph G with vertex set V and edge set E is an assignment of positive integer labels {1, 2, ..., k} to both vertices and edges so that the weights calculated at vertices are distinct. The total vertex irregularity strength of G, denoted by tvs(G)is the minimum value of the largest label k over all such irregular assignment. In this paper, we study the to...

The performance of automatic vehicle identification systems based on automatic number plate recognition can be improved radically with the addition of vehicle make and model recognition systems. Current approaches recognize make and model when the query image contains a properly segmented vehicle with no background clutter. In this paper, we present a new probabilistic patch based framework to ...

Microsoft attempted to implement theWichmann–Hill RNG in Excel 2003 and failed; it did not just produce numbers between zero andunity, itwould also produce negative numbers. Microsoft issued a patch that allegedly fixed the problem so that the patched Excel 2003 and Excel 2007 now implement the Wichmann–Hill RNG, as least according to Microsoft. We show thatwhatever RNG it is thatMicrosoft has ...

A partition of a natural number n is any integer sequence λ = (λ1, λ2, . . . ) such that λ1 ≥ λ2 ≥ · · · ≥ 0 and λ1 + λ2 + · · · = n (notation: λ ⊢ n). In particular, λ1 = max{λi ∈ λ}. Every partition λ ⊢ n can be represented geometrically by a planar shape called the Young diagram, consisting of n unit cell arranged in consecutive columns, containing λ1, λ2, . . . cells, respectively. On the s...

Using the basic fact that any formal power series over the real or complex number field can always be expressed in terms of given polynomials {pn(t)}, where pn(t) is of degree n, we extend the ordinary Riordan array (resp. Riordan group) to a generalized Riordan array (resp. generalized Riordan group) associated with {pn(t)}. As new application of the latter, a rather general Vandermonde-type c...
