Recent studies on immigrants’ health shed light on the importance of selection and acculturation processes, but also point out differences according to the country of origin. We study how differences in overweight between natives and immigrants can vary according to birthplace, country of arrival, acculturation, and socioeconomic status. Based on national health interview surveys in Spain and F...

This paper presents two results on the dynamical behaviour of some finite binary one-dimensional threshold automata, where the interaction coefficient between two cells i, j is a decreasing function of ii-jl.

To provide an objective measure of the correlation between the internal energy content of ions generated by matrix-assisted laser desorption/ionization (MALDI) and the matrix properties, a series of well-characterized benzyl-substituted benzylpyridinium salts were used as thermometer molecules (TMs). To determine the internal energy variations of analyte ions, the survival yields of TM molecula...

In this work, the e-PPC-SAFT equation of state has been parameterized to predict phase equilibrium system H2 + CH4 H2O Na+Cl? in conditions temperature, pressure and salinities interest for gas storage salt caverns. The ions parameters have adjusted match salted water properties such as mean ionic coefficient activities, vapor pressures molar densities. Furthermore, binary interaction between h...

Characterizing fundamental ion transport is necessary for the modification and development of electrolytes. In this study, we investigated local bulk properties 1 M NaPF6 in binary EC:PC (1:1), ternary 5EC:3PC:2DEC (5:3:2) solvents, as well their 2 wt.% FEC modulated versions. We determined 1H, 19F 23Na Nuclear Magnetic Resonance (NMR) spin-lattice relaxation time (T1), self-diffusion coefficie...

where x̄ and ȳ are the sample means of both variables. ρ measures whether, on average, xi and yi are associated. For a single variable, say x, I will measure whether xi and xj , with i 6= j, are associated. Note that with ρ, xi and xj are not associated since the pairs (xi, yi) are assumed to be independent of each other. In the study of spatial patterns and processes, we may logically expect th...

Let Lk denote the Lebesgue constants of the Walsh system. The following exact result is established by means of Mellin transforms: ∑ 1≤k<n Lk = n 4 log2 n+ nF (log2 n)− Ln 2 , for n ≥ 1, where F (u) is a continuous periodic function with period 1 whose Fourier coefficients can be explicitly expressed in terms of Riemann’s zeta function. This improves an old result of Fine.

We estimate Fourier coefficients of a Boolean function which has recently been introduced in the study of read-once branching programs. Our bound implies that this function has an asymptotically “flat” Fourier spectrum and thus implies several lower bounds of its various complexity measures.

Based upon the formalism recently developed by one of us (MS), we analytically perform the post-Newtonian expansion of gravitational waves from a test particle in circular orbit of radius r0 around a Schwarzschild black hole of mass M . We calculate gravitational wave forms and luminosity up to v8 order beyond Newtonian, where v = (M/r0) 1/2. In particular, we give the exact analytical values o...

Programs capable of running on small computers accept designer's lines from two-dimensional curves and allow them to be faired into a threedimensional surface of smoothly blended contours. Hydrodynamic performance is not calculated directly, but information which will help the designer determine this is available from the program outputs. Calculations are speedily performed for displacement, th...
