We introduce a fast algorithm for the numerical application to arbitrary vectors of several special function transforms. The algorithm requires O(n log(n)) operations to apply to an arbitrary vector any n×n matrix such that the rank of any p×q contiguous submatrix is bounded by a constant times pq/n. These rank bounds are proven here for the case of the Fourier-Bessel transform. Numerical exper...

abstract background: pregnancy can be in conflict with sexual function which can be affected by physical and psychological changes during pregnancy. therefore, comparison of the effect of face‑to‑face education with group education on sexual function during pregnancy in couples was the purpose of this research. materials and methods: in this quasi‑experimental pre‑test post‑test study, 64 pregn...

Let X be a a complete hyperbolic threefold of a finite volume with only one cusp. For a unitary local system ρ of rank one on X, one may associte the Ruelle L-function Rρ(z). Suppose the restriction of ρ to the cusp is nontrivial. We will show that the Ruelle L-function has a pole at the origin whose order is equal to −2dimH(X, ρ). Moreover we will prove if dimH(X, ρ) is zero Rρ(0) is equal to ...

Native proteins perform an amazing variety of biochemical functions, including enzymatic catalysis, and can engage in protein-protein and protein-DNA interactions that are essential for life. A key question is how special are these functional properties of proteins. Are they extremely rare, or are they an intrinsic feature? Comparison to the properties of compact conformations of artificially g...

this paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. to this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. the g...

The purpose of the current study was to evaluate a new measure, the Autism Self-Efficacy Scale for Teachers (ASSET) for its dimensionality, internal consistency, and construct validity derived in a sample of special education teachers (N = 44) of students with autism. Results indicate that all items reflect one dominant factor, teachers' responses to items were internally consistent within the ...

Previous work from our laboratories has shown that monolingual Japanese adults who were given intensive high-variability perceptual training improved in both perception and production of English /r/-/l/ minimal pairs. In this study, we extended those findings by investigating the long-term retention of learning in both perception and production of this difficult non-native contrast. Results sho...

I argue that there are at least two concepts of law of nature worthy of philosophical interest: strong law and weak law. Strong laws are the laws investigated by fundamental physics, while weak laws feature prominently in the “special sciences” and in a variety of non-scientific contexts. In the first section, I clarify my methodology, which has to do with arguing about concepts. In the next se...

Twenty-five years ago educational services for children with disabilities were frequently fragmented, underfunded, highly segregated, and unreliable. Public schools were often ill prepared and unwilling to provide special and necessary services to children with disabilities. Over the past two decades, efforts to provide an appropriate education for children with disabilities in America—through ...
