background and aims: one of the main goals of standard orthodontic treatment is having the roots of teeth adjacent to extraction sites parallel to each other. the purpose of this study was to compare standard edgewise and preadjusted straight wire (mbt) methods in achieving this goal. materials and methods: for comparing root parallelism, 228 maxillary quadrants and 225 mandibular quadrants of ...

In this article, the aim of the authors is to study the role of repetition in creating music and parallelism in Nimayee poems in the three collections of poems by Mehdi Akhavan Sales: Zamestan, Akhere Shahname and Az Avesta. Accordingly, the researchers have investigated the various manners of repetition in creating parallelism in the poems at three levels: phonological parallelism, lexical par...

The Schur method for computing a matrix square root reduces the matrix to the Schur triangular form and then computes a square root of the triangular matrix. We show that by using either standard blocking or recursive blocking the computation of the square root of the triangular matrix can be made rich in matrix multiplication. Numerical experiments making appropriate use of level 3 BLAS show s...

Developing software applications for emerging and future heterogeneous systems with diverse combinations of hardware is significantly harder than for homogeneous multicore systems. In this paper, we identify three root causes that underlie the programming challenges: (1) diverse parallelism models; (2) diverse memory architectures; and (3) diverse hardware instruction set semantics. We believe ...

Mark Twain made use of repetition and parallelism as two comedic literary devices to bring comic effect to the readers. Linguistic devices of humor, repetition and parallelism seemed to create many difficulties in the translation of literary texts. The present study applied Delabatista‟s strategies for translating wordplays such as repetition and parallelism in the translation of humorous texts...
