introduction : the purpose of this study was to examine and compare the social adjustment in balanced and non-balanced patterns of the parent-child relationship.  methods : the research population was all female gifted students in the farzanegan high school in the first educational district of tehran in 2013-14. the sample research included 96 female gifted students who answered the parent-chil...

We use generating functions over group rings to count polynomials finite fields with the first few coefficients and a factorization pattern prescribed. In particular, we obtain different exact formulas for number of monic n-smooth degree m field, as well prescribed trace coefficient.

The properties of nonlinear interference pattern between atomic bright solitons are characterized analytically, with the aid exact solutions dynamical equation in mean-field approximation. It is shown that relative velocity, phase, and interaction strength can be measured from pattern. proposed to design soliton interferometry Bose–Einstein condensate. As an example, we apply them measure gravi...

How do the k-core structures of real-world graphs look like? What are the common patterns and the anomalies? How can we use them for algorithm design and applications? A k-core is the maximal subgraph where all vertices have degree at least k. This concept has been applied to such diverse areas as hierarchical structure analysis, graph visualization, and graph clustering. Here, we explore perva...

An n × n sign pattern Sn is spectrally arbitrary if, for any given real monic polynomial g(x) of degree n, there is a real matrix having sign pattern Sn and characteristic polynomial g(x). All n × n star sign patterns that are spectrally arbitrary, and all minimal such patterns, are characterized. This subsequently leads to an explicit characterization of all n × n star sign patterns that are p...
