Bayesian Model Comparison and Analysis of the Galactic Disk Population of Gamma-Ray Millisecond Pulsars

Pulsed emission from almost one hundred millisecond pulsars (MSPs) has been detected in $\gamma$-rays by the Fermi Large-Area Telescope. The global properties of this population remain relatively unconstrained despite many attempts to model their spatial and luminosity distributions. We perform here a self-consistent Bayesian analysis of both the spatial distribution and luminosity function simultaneously. Distance uncertainties, arising from errors in the parallax measurement or Galactic electron-density model, are marginalized over. We provide a public Python package for calculating distance uncertainties to pulsars derived using the dispersion measure by accounting for the uncertainties in Galactic electron-density model YMW16. Finally, we use multiple parameterizations for the MSP population and perform Bayesian model comparison, finding that a broken power law luminosity function with Lorimer spatial profile are preferred over multiple other parameterizations used in the past. The best-fit spatial distribution and number of $\gamma$-ray MSPs is consistent with results for the radio population of MSPs.Comment: 13 pages, 8 figures, 3 tables + Appendix.

Spin Dependence of Deep Inelastic Diffraction

Using a perturbative model for diffractive interactions, we derive an expression for the polarized diffractive structure function $g_1^D$ in the high energy limit. This structure function is given by the interference of diffractive amplitudes with polarized and unpolarized exchanges. For the polarized exchange we consider both two-gluon and quark-antiquark amplitudes. The polarized diffractive amplitude receives sizable contributions from non-strongly ordered regions in phase space, resulting in a double logarithmic enhancement at small $x$. The resummation of these double logarithmic terms is outlined. We also discuss the transition from our perturbative expression to the nonperturbative region. A first numerical estimate indicates that the perturbative contribution to the spin asymmetry is substantially larger than the nonperturbative one.Comment: 16 pages, LaTeX, 1 figure include

Spatial distribution of ions in a linear octopole radio-frequency ion trap in the space-charge limit

We have explored the spatial distribution of an ion cloud trapped in a linear octopole radio-frequency (rf) ion trap. The two-dimensional distribution of the column density of stored silver dimer cations was measured via photofragment-ion yields as a function of the position of the incident laser beam over the transverse cross section of the trap. The profile of the ion distribution was found to be dependent on the number of loaded ions. Under high ion-loading conditions with a significant space-charge effect, ions form a ring profile with a maximum at the outer region of the trap, whereas they are localized near the center axis region at low loading of the ions. These results are explained quantitatively by a model calculation based on equilibrium between the space-charge-induced potential and the effective potential of the multipole rf field. The maximum adiabaticity parameter \eta_max is estimated to be about 0.13 for the high ion-density condition in the present octopole ion trap, which is lower than typical values reported for low ion densities; this is probably due to additional instability caused by the space charge.Comment: 8 pages, 5 figure

Consumer acceptance of novel fruits and fruit products

The task of the Deliverable 1.3.7 Report on case studies of fruit innovations is to provide information on consumers' acceptance of innovative fruit and fruit products selected for case studies in Deliverable 1.3.2 List of selected fruit innovations, and to validate findings from previous stages of WP 1.3 research. The task of the Deliverable 1.3.9 List of characteristics for future fruit innovations is to provide a list of product characteristics and recommendations that can increase the success of fruit innovations in the future. This report presents results of case studies carried out in February and March, 2010, in four European countries: Greece, the Netherlands, Poland and Spain. It also presents product characteristics accepted by consumers and recommendations for development of future innovative fresh fruits and fruit products, as well as recommended strategies and policies, which were formulated on the basis of findings of case study and previous stages of WP1.3 research and their validation

Colored Spin Systems, BKP Evolution and finite N_c effects

Even within the framework of the leading logarithmic approximation the eigenvalues of the BKP kernel for states of more than three reggeized gluons are unknown in general, contrary to the planar limit case where the problem becomes integrable. We consider a 4-gluon kernel for a finite number of colors and define some simple toy models for the configuration space dynamics, which are directly solvable with group theoretical methods. Then we study the dependence of the spectrum of these models with respect to the number of colors and make comparisons with the large limit case.Comment: 17 pages, 4 figures, references update, to appear on EPJ

Consumer acceptance of novel fruits and fruit products

This report presents results of the consumer survey that was conducted in November, 2009, in four European countries – Poland, the Netherlands, Greece and Spain within WP 1.3 of ISAFRUIT Project. In the current deliverables (D1.3.5 and D1.3.8), the authors first focused on the influence of personal characteristics of the respondents, the evaluation of general fruit product characteristics, product evaluations of specific novel fresh fruits and fruit products and demographics on consumers' acceptance of fruit innovations. Furthermore, they identified cross cultural consumer segments, who each value different product characteristics. Moreover, these consumer segments differ in demographics, their willingness to accept fruit innovations and their personal characteristics. Policy recommendations for future product development of fresh fruits and fruit products and communication strategies were formulated, based on the results of the consumer survey and the identified cross cultural consumer segments
