In a sample of 291 adolescents (mean age 13 yr), seven psychosocial factors, including family support, were examined in relation to accelerometry-derived physical activity (PA) measured after school and during the weekend. Genderspecific stepwise linear regression analyses determined which combinations of factors explained the variance in nonschool moderate to vigorous PA and nonschool total PA after adjusting for % BF, age, and maturity (p ≤ 0.05). Being praised by a family member and % BF explained 13% of the variance in female nonschool MVPA, while being praised and maturity explained 13% of the variance in nonschool total PA. Having a family member watch him participate, % BF, and age explained 11.5% of the variance in male nonschool MVPA, while having a family member participate with him explained 6.4% of the variance in nonschool total PA. Despite adolescents' growing independence, family support continues to influence PA levels. © 2012 Human Kinetics, Inc.

We consider the groupoid C*-dynamical systems (A, G, α) where A is a C*-algebra in B(H),G is a certain groupoid, and α is an embedding groupoid action of G, acting on A in B(H). In particular, we are interested in the case where the groupoid G is a fractaloid, a groupoid with fractal property. Moreover, we restrict our interests to the case where G is generated by finitely many partial isometries in B(H). We observe the basic properties of such C*-dynamical systems. © 2009 Birkhäuser Verlag Basel/Switzerland.

In this paper, by establishing free-probabilistic models on the Hecke algebras (Formula presented.) , we construct canonical free probability spaces (Formula presented.) , where (Formula presented.) , for primes (Formula presented.). Dependent upon such free-probabilistic structures, we study corresponding representations of (Formula presented.) , and consider spectral properties of operators realized under representations. © 2014, Springer Basel.

In this paper, we study certain (Formula presented.)-valued functions induced by given graphs called graph zeta functions. In particular, we are interested in factorizations of such functions. We show that the factorizations of graph zeta functions are characterized by certain subgraphs of given graphs. Based on this factorization property on graph zeta functions, we define-and-study the non-factorizability of graphs. © 2015 Springer Basel

This project is focused on increasing enrollment and graduation rates in industrial engineering, mechanical engineering and physics. The expectation is to serve more than 15 students yearly through the articulation of a seamless transfer from the community clleges. It is particularly noteworthy that the program builds on proven in house methods that have yielded excellent retention results and that it continues to focus on underserved populations. Enhancements to be included are adopting and enhancing a STEM Summer Research Program and a Student Success Center, hiring tutors and research assistants, faculty mentors to help with retention, utilizing good connections with industry, and integrating two good recruitment tools (Girls Night Out and The Robotic Hand).
