fe49co33ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 oe and 0.58 to200 oe and 0.105, respectively), indicating the increase in m...

We establish a composition theorem of Stepanov almost periodic functions, and, with its help, a composition theorem of Stepanov-like pseudo almost periodic functions is obtained. In addition, we apply our composition theorem to study the existence and uniqueness of pseudo-almost periodic solutions to a class of abstract semilinear evolution equation in a Banach space. Our results complement a r...

In this paper, we are concerned with new weighted pseudo almost periodic solutions of the semilinear evolution equations with nonlocal conditions x′(t) = A(t)x(t) + f(t, x(t)), x(0) = x0 + g(x), t ∈ R. By applying the Banach fixed point theorem, the theory of the measure theory, the theory of semigroups of operators to evolution families and the properties of a class of new weighted pseudo almo...

Recent work on public goods contributions has examined the relationship between gender and free-riding behavior in studies using laboratory public goods. This research furthers this line of inquiry by examining gender as a possible explanation of hypothetical bias, which occurs in valuation studies using real world public goods. Results show that gender differences exist in hypothetical valuati...

We present a theorem of Kollár on the density property of valued PAC fields and a theorem of Abraham Robinson on the model completeness of the theory of algebraically closed non-trivial valued fields. Then we prove that the theory T of non-trivial valued fields in an appropriate first order language has a model completion T̃ . The models of T̃ are non-trivial valued fields (K, v) that are ω-imper...

Motivated by [17], in this paper, wegive sufficient conditions ensuring that the space SpPAP(R,Z, ?, ?) of (?, ?)-pseudo almost periodic functions Stepanov?s sense is invariant translation. Also, we provide new composition theorems Stepanov.
