In this work are studied the Jacobians of certain singular transformations and the corresponding measures which support the jacobian computations.

BACKGROUND The effect of peer-led training in basic life support (BLS) in the education of medical students has not been assessed. SUBJECTS AND METHODS This study was a randomized controlled trial with a blinded outcome assessor. A total of 74 fourth-year medical students at Ehime University School of Medicine, Japan were randomly assigned to BLS training conducted by either a senior medical ...

The proposition is advanced that many current measures of kinship strength may paradoxically indicate inadequate or weakened kinship structures. That is so because they rely on measures that emphasize continuous proximity. This curious paradox is a consequence of inattention to the relationship between technology, services, and proximity. This article presents nonproximity indicators of kinship...

Our main result states that two signed measures μ and ν with bounded support contained in the zero set of a polynomial P (x) are equal if they coincide on the subspace of all polynomials of polyharmonic degree NP where the natural number NP is explicitly computed by the properties of the polynomial P (x). The method of proof depends on a definition of a multivariate Markov transform which is an...

The goal of this paper is the construction of measures μ on R(n)enjoying three conflicting but fortunately compatible properties: (i) μ is a sum of weighted Dirac masses on a locally finite set, (ii) the Fourier transform μ f μ is also a sum of weighted Dirac masses on a locally finite set, and (iii) μ is not a generalized Dirac comb. We give surprisingly simple examples of such measures. These...
