This paper describes the application of hypergraph grammars to drive a linear computational cost solver for grids with point singularities. Such graph grammar productions are the first mathematical formalisms used to describe solver algorithms, and each indicates the smallest atomic task that can be executed in parallel, which is very useful in the case of parallel execution. In particular, the...

The rare decays B ! K `` , B ! K )  and Bs ! + are analyzed in a generic scenario where New Physics e ects enter predominantly via Z penguin contributions. We show that this possibility is well motivated on theoretical grounds, as the sbZ vertex is particularly susceptible to non-standard dynamics. In addition, such a framework is also interesting phenomenologically since the sbZ coupling is r...

Purpose – This study examines the relationships between a firm’s CSR activities and its performance and risk. We hypothesize that industry-level effects are highly determinant of the sign and magnitude of these relationships to establish a ranking of industries to identify the position of the most prominent tourism-related industries: hotels and airlines. Based on the cybernetic model of decisi...

We report our results on nonlinear optical properties of 2(3), 9(10), 16(17), 23(24) tetra tert-butyl phthalocyanine and 2(3), 9(10), 16(17), 23(24) tetra tert-butyl Zinc phthalocyanine studied using Z-scan technique with 800 nm femtosecond and 532 nm nanosecond pulses. Nonlinear absorption behavior in both femtosecond and nanosecond domains was studied in detail. We observed three-photon absor...

We study direct CP violation in hadronic B-decays in the ρ 0-ω interference region, and focus specifically on the rate asymmetry in B ± → ρ ± ρ 0 (ω) → ρ ± π + π −. In this channel, the strong phase is dominated by isospin violation, so that it can be essentially determined by e + e − → π + π − data in the ρ 0-ω interference region. We find that the asymmetry in the ρ ± π + π − channel is of or...

BACKGROUND This study aimed to assess the effect of new package of interventions on scientific productions rate in Shahid Beheshti University of Medical Sciences. METHODS Through a health system research, we extracted policies from the strategic plan of the university and 10 interventions were developed to increase the scientific productions in terms of quality, quantity and commercialization...

The acquisition of a foreign phonetic contrast requires the second language (L2) learner to attend to those acoustic dimensions that are informative for the distinction and to manipulate values along those dimensions during production. The discovery of informative dimensions in L2 can be complicated by the contrasts present in the native (L1) language. A well-known example is the difficulty tha...

In this paper, a new method is introduced for improving the efficiency of the Residue Number System, which uses both binary and residue representations in order to represent a number. A residue number system uses the remainder of the division in several different modules. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

This study was an attempt to investigate the developmental rate of fluency, accuracy and complexity among 12 EFL learners within the framework of chaos complexity theory. To carry out this study, 6 female and 6 male participants in two levels of proficiency (pre-and upper-intermediate) were put in two classes taught by the same teacher and following the same course. Every two months (for a peri...
