Speech production requires the precise control of vocal tract movements to generate individual speech sounds (phonemes) which, in turn, are rapidly organized into complex sequences. Multiple productions of the same phoneme can exhibit substantial variability, some of which is inherent to control of the vocal tract and its biomechanics, and some of which reflects the contextual effects of surrou...

introduction: since international increase of scientific productions is an indicator in assessing different countries, the purpose of this research is to investigate the scientific productions of iranian type i pharmacy faculty members (universities of isfahan, tabriz, shiraz, tehran and mashhad) in the institute for scientific information (isi) during 2006-2008. methods: in this scientometric ...

In March 2020, more than 100 governments around the world imposed partial or full lockdown policies prohibiting people to leave their homes except for activities deemed essential (e.g. procuring food, going work) reduce SARS-CoV-2 transmissions. Furthermore, authorities, media and peers encouraged adopt physical distancing behaviors, requesting not touch each other even keep a distance of at le...

The evolution of digital technologies in all sectors of society, including education, implies a paradigm shift in teaching methods. In Portugal, the new national curriculum for Portuguese language teaching at Elementary School level highlights the role of technologies, considering that these new methods, “require mastery of multiple literacies, namely digital and computer literacies – associate...

Polynomial threshold gates are basic processing units of an artificial neural network. When the input vectors are binary vectors, these gates correspond to Boolean functions and can be analyzed via their polynomial representations. In practical applications, it is desirable to find a polynomial representation with the smallest number of terms possible, in order to use the least possible number ...

We study the phase structure and condensates of two-flavor QCD at finite isospin chemical potential in the framework of a confining, Dyson-Schwinger equation model. We find that the pion superfluidity phase is favored at high enough isospin chemical potential. A new gauge invariant mixed quark-gluon condensate induced by isospin chemical potential is proposed based on Operator Product Expansion...

These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras. Then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generator...

The Υ(1S + 2S + 3S) → ee cross section is measured at mid-rapidity (y) in p + p collisions and in d+Au collisions at center-of-mass energy √ s = 200 GeV with the STAR detector at RHIC. In p + p, the measured cross section is found to be consistent with the world data trend as a function of √ s, in agreement with the Color Evaportaion Model (CEM), and underestimated by the Color Singlet Model (C...
