The authors compute the dynamical phase diagram for relaxation of a classical spin, exchange coupled to local magnetic moment at an edge site one-dimensional spinful Su-Schrieffer-Heeger model. role topological state and its internal Zeeman splitting spin-relaxation process, as well incomplete spin on long time scales, can be explained within framework renormalized linear response approach, whe...

influence of soil organic matter (som) on the adsorption, desorption and transport of polycyclic aromatic hydrocarbons (pahs) has already been given full investigation in soils. in this paper, confocal laser scanning microscope (clsm) was used to elucidate aqueous leaching of pahs in different types of soil with soil columns, which enhanced understanding on transport of pahs appreciably. four t...

Using the calculation of coefficients multiple linear regression two-dimensional correlation, we studied mutual influences (functional connectivity) between amplitudes EEG rhythms in people with mental retardation. Multiple equations were geometrically interpreted using polycyclic multigraphs. As a result studies and calculations, it was found that retardation, number correlation is determined ...

background & objective : there are over 3 million mental retarded all over the world. so that promotion of oral and dental health of these patients is one of the major challenges in every society. this study was conducted to determine the periodontal treatment needs for these patients in tabriz institutes.   materials & methods : three hundred and eighty six mental retarded patients between 4 t...

introduction: congenital hypothyroidism is the most common cause of mental retardation in the world. the presence of hypothyroidism in fetal is lead to abnormalities in major organs, including nervous system and central skeleton. aim of this study was to investigate epidemiologic situation of neonatal hypothyroidism in ilam province between 2005 -2011. materials and methods: this was a cross-se...

Radially symmetric pupil plane phase retardation functions are derived that extend focal depth and alleviate third-order spherical aberration (SA) effects. The radial symmetry of these functions means that they can be more conveniently manufactured by use of traditional techniques such as diamond machining than previously reported filters with rectangular symmetry. The method employs minimizati...
