That’s what makes the report from Philadelphia so exciting. It’s the latest in a small but growing series of studies that point to the first signs of declining rates of obesity among children in places like New York City and California (2,3). In New York City, declines were seen citywide, but the largest changes were among white and Asian students, who already had the lowest rates (2). In Calif...

1886 CMAJ, November 8, 2011, 183(16) © 2011 Canadian Medical Association or its licensors Jusie (Yoo-sie) had many stories to tell and I only had an hour before I had to catch my flight back to Montréal. “I could tell you stories for two days,” he said, gesturing from the chair beside my desk. Jusie was 82 years old and had been referred to me for quite another matter. A small compact man with ...

Most studies of the relation between economic freedom and growth of GDP have found a positive relation. One problem in this area is the choice of economic freedom measure. A single measure does not reflect the complex economic environment and a highly aggregated index makes it difficult to draw policy conclusions. In this paper we investigate what specific types of economic freedom measures tha...

We propose the theory of quantum gravity with interactions introduced by topological principle. The fundamental property of such a theory is that its energymomentum tensor is an BRST anticommutator. Physical states are elements of BRST cohomology group. The model with only topological excitations, introduced recently by Witten is discussed from the point of view of induced gravity program. We f...

Eigenstates of two-dimensional charged electron-hole complexes in magnetic fields are considered. The operator formalism that allows one to partially separate the center-of-mass motion from internal degrees of freedom is presented. The scheme using magnetic translations is developed for calculating in strong magnetic fields the eigenspectra of negatively charged excitons X−, a bound state of tw...

Exotic Mesons and Hadrons are high energy states of Quark oscillations. Taking into account the Planck Distribution Law of the electromagnetic oscillators, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Lattice QCD gives the same results as the diffraction patterns of the electromagnetic oscillators, explaining the color confinement and the asymptotic freedom...

We will discuss recent results on the thermodynamics of QCD in the presence of light dynamical quark degrees of freedom. In particular, we will concentrate on an analysis of the flavour and quark mass dependence of the QCD phase diagram, the equation of state and the transition temperature. Moreover, we present recent results on the heavy quark free energy.

This paper addresses the dimensional synthesis of parallel kinematics machines. A multiobjective optimization problem is proposed in order to determine optimum structural and geometric parameters of parallel manipulators. The proposed approach is applied to the optimum design of a three-degree-of-freedom planar parallel manipulator in order to minimize the mass of the mechanism in motion and to...

A systematic analysis is performed on the effectiveness of removing degrees of freedom from hydrogen atoms andror increasing hydrogen masses to increase the efficiency of molecular dynamics simulations of hydrogen-rich systems such as proteins in water. In proteins, high-frequency bond-angle vibrations involving hydrogen atoms limit the time step to 3 fs, which is already a factor of 1.5 beyond...

Title of Document: FREEDOM TO TWEET OR TWEET TO FREEDOM: THE RELATIONSHIP BETWEEN FREEDOM STATUS AND TWEETS DURING ELECTIONS Zahra Ashktorab, Master of Science 2013 Directed By: Jen Golbeck, Assistant Professor, College of Information Studies In this thesis, I conduct an exploratory study of the relationship between a country's freedom and the twitter activity during elections. While there have...
