A review of sample preparation and its influence on pH determination in concrete samples [PDF]
, 2017 If we are to monitor the chemical processes in cementitious materials, then pH assays in the pore solutions of cement pastes, mortars, and concretes are of key importance.

Biomédica: revista del Instituto Nacional de Salud, 2010 Introducción. Una de las mayores dificultades en el control de la tuberculosis es la detección tardía de casos, lo que obedece, entre otros motivos, a la poca búsqueda activa de casos sintomáticos respiratorios entre los consultantes y al reducido número

Fredholm determinants, Anosov maps and Ruelle resonances [PDF]
arXiv, 2005 I show that the dynamical determinant, associated to an Anosov diffeomorphism, is the Fredholm determinant of the corresponding Ruelle-Perron-Frobenius transfer operator acting on appropriate Banach spaces. As a consequence it follows, for example, that the zeroes of the dynamical determinant describe the eigenvalues of the transfer operator and the ...

Progress on neural parton distributions
, 2007 We give a status report on the determination of a set of parton distributions based on neural networks. In particular, we summarize the determination of the nonsinglet quark distribution up to NNLO, we compare it with results obtained using other ...

Inventiones mathematicae, 1996 We introduce a sharp trace Tr# Open image in new window and a sharp determinant Det#(l−z Open image in new window ) for an algebra of operators Open image in new window acting on functions of bounded variation on the real line. We show that the zeroes of the sharp determinant describe the discrete spectrum of Open image in new window .

Some properties of associated spaces with sub-Hankel determinants [PDF]
arXiv, 2016 In this note, we show that the space associated with sub-Hankel determinant is a non-reductive, regular prehomogeneous vector space, and we give the multiplicative Legendre transforms of sub-Hankel determinants. Moreover we observe certain relations between $b$-functions of polarization of PVpolynomials and $b$-functions of sub-Hankel determinants, and

, 2012 Multicellular animals are a diverse lot, with widely varied body plans and lifestyles. One feature they share, however, is a nearly universal reliance on sexual reproduction for species propagation.

Functional gold nanoparticles for sensing applications
Nanotechnology Reviews, 2013 Nanoparticle-based technologies have played important roles in providing opportunities for the development of a new generation of sensing tools. Because of their unique optical, chemical, electrical, and catalytic properties, gold nanoparticles (AuNPs ...

Generalisations of the determinant to interdimensional transformations: a review [PDF]
arXiv, 2019 Significant research has been carried out in the past half-century on defining generalised determinants for transformations between (typically real) vector spaces of different dimensions. We review three different generalisations of the determinant to non-square matrices, that we term for convenience the determinant-like function, the vector ...
