A chemical non-equilibrium form of the superconductor like potential in the EW theory has been derived. It is obtained from the rate-equation for binding of fermions (quarks) to antifermions (antiquarks) and the spatial correlations for such pairs. In this model, the dimensionless coupling becomes a function of the fermion and antifermion field amplitudes, providing a measure of the matter-antimatter asymmetry from which the ratio between ordinary mass and dark mass is obtained. The dark mass becomes related to the Higgs boson mass and is estimated to about 192 GeV, which could be consistent with a signal observed from the Milky Way.

“…Finally, one must note that for ∆t ≥ 120 min, the number of points was inadequate to provide any proper estimate at all. 7 More precisely, we increased ϕ from 0 by increments of 0.2 and looked for λ(k, ϕ) ≈ λ(ϕ). The method is very sensitive to the proper choice of ϕ.…”

“…An ubiquitous aspect of strongly interacting systems is the lack of finite scales. The best understood examples are second order equilibrium phase transitions where renormalization group theory provides a general explanation of scaling and universality [7]. It seems that some features of the stock market can indeed be captured by these concepts: For example, the so called inverse cube law of the distribution of logarithmic returns shows a quite convincing data collapse for different companies with a good fit to an algebraically decaying tail [8,9].…”

Size matters: some stylized facts of the stock market revisited

We reanalyze high resolution data from the New York Stock Exchange and find a monotonic (but not power law) variation of the mean value per trade, the mean number of trades per minute and the mean trading activity with company capitalization. We show that the second moment of the traded value distribution is finite. Consequently, the Hurst exponents for the corresponding time series can be calculated. These are, however, non-universal: The persistence grows with larger capitalization and this results in a logarithmically increasing Hurst exponent. A similar trend is displayed by intertrade time intervals. Finally, we demonstrate that the distribution of the intertrade times is better described by a multiscaling ansatz than by simple gap scaling. Understanding the financial market as a self-adaptive, strongly interacting system is a real interdisciplinary challenge, where physicists strongly hope to make essential contributions [1,2,3]. The enthusiasm is understandable as the breakthrough of the early 70's in statistical physics taught us how to handle strongly interacting systems with a large number of degrees of freedom. The unbroken development of this and related disciplines brought up several concepts and models like (fractal and multifractal) scaling, frustrated disordered systems, or far from equilibrium phenomena and we have obtained very efficient tools to treat them. Many of us are convinced, that these and similar ideas and techniques will be helpful to understand the mechanisms of the economy. In fact, there have been quite successful attempts along this line [4,5,6]. An ubiquitous aspect of strongly interacting systems is the lack of finite scales. The best understood examples are second order equilibrium phase transitions where renormalization group theory provides a general explanation of scaling and universality [7]. It seems that some features of the stock market can indeed be captured by these concepts: For example, the so called inverse cube law of the distribution of logarithmic returns shows a quite convincing data collapse for different companies with a good fit to an algebraically decaying tail [8,9]. PACSStudies in econophysics concentrate on the possible analogies, although there are important differences between physical and financial systems. This is, of course, a trivial statement -it is enough to refer to the abovementioned self-adaptivity, to the possibility of influencing a

“…Indirect methods measure a parameter related to the sublimation energy. In many cases it is determined from the vapor pressure of the substance under study at different temperatures and then, using the Clapeyron equation, the energy of sublimation is derived [4]. Vapor pressure is usually calculated by measuring the mass flow from an oven at controlled temperature by using a Knudsen effusive cell [5].…”

Elsevier Luna, R.; Millan, C.; Domingo, M.; et ál..(2012). Upgraded sublimation energy determination procedure for icy films. Vacuum. 86(12):1969Vacuum. 86(12): -1973Vacuum. 86(12): . doi:10.1016Vacuum. 86(12): /j.vacuum.2012 AbstractA method to determine the sublimation energy of a bulk ice in high vacuum systems, allowing other simultaneous analysis techniques, is presented. Variation in frequency of a quartz crystal microbalance, due to sublimating material, during a zeroth-order desorption consents to obtain this energy. CO2 sublimation energy is obtained to check this method, its value is coherent with that reported in the literature. Our method permits to simplify the setup used so far by other authors, and to obtain relevant parameters for ices simultaneously. The procedure explained here corrects the temperature frequency dependance of the microbalance and the effect of contaminants by using an unique microbalance.
