Inclusive hadron and photon production at LHC in dipole momentum space

Using a momentum space model for the dipole scattering amplitude we present an analysis of the saturation effects at LHC energies, describing the data on proton-proton and proton-lead collisions. The model is based on the asymptotic solutions of the Balitsky-Kovchegov equation, being ideal in the saturation domain where the target wave function has a high occupation number. We also make predictions for the nuclear modification ratios on charged hadron and prompt photon production in the forward region, where the high parton density effects are important.Comment: New section added and typos corrected.

A comparison of efficient permutation tests for unbalanced ANOVA in two by two designs--and their behavior under heteroscedasticity

We compare different permutation tests and some parametric counterparts that are applicable to unbalanced designs in two by two designs. First the different approaches are shortly summarized. Then we investigate the behavior of the tests in a simulation study. A special focus is on the behavior of the tests under heteroscedastic variances.Comment: 20 pages, 9 figures, Working Paper of the Department of Management And Enigineering of the University of Padov

Direct calorimetric measurements of isothermal entropy change on single crystal W-type hexaferrites at the spin reorientation transition

We report on the magnetic field induced isothermal entropy change, \Delta s(Ha, T), of W-type ferrite with CoZn substitution. Entropy measurements are performed by direct calorimetry. Single crystals of the composition BaCo$_0.62$Zn$_1.38$Fe$_16$O$_27$, prepared by the flux method, are measured at different fixed temperatures under an applied field perpendicular and parallel to the c axis. At 296 K one deduces a value of K$_1$ = 8.7 \times 10^{4} J m$^-3$ for the first anisotropy constant, which is in good agreement with the literature. The spin reorientation transition temperature is estimated to take place between 200 and 220 K

Is demagnetization an efficient optimization method?

Demagnetization, commonly employed to study ferromagnets, has been proposed as the basis for an optimization tool, a method to find the ground state of a disordered system. Here we present a detailed comparison between the ground state and the demagnetized state in the random field Ising model, combing exact results in $d=1$ and numerical solutions in $d=3$. We show that there are important differences between the two states that persist in the thermodynamic limit and thus conclude that AC demagnetization is not an efficient optimization method.Comment: 2 pages, 1 figur

European Museums in the 21st Century: Setting the Framework (3 Voll.)

This book grew out of the earliest work of the MeLa Research Field 6, “Envisioning 21st Century Museums,” aimed at exploring current trends in European contemporary museums. Analysing their ongoing evolution triggered by this “age of migrations” and with specific attention to their architecture and exhibition design, the volume collects the preliminary observations ensuing from this survey, complemented by the some paradigmatic examples, and further enriched by interviews and contributions from scholars, curators and museum practitioners. With contributions by Florence Baläen, Michela Bassanelli, Luca Basso Peressut, Joachim Baur, Lorraine Bluche, Marco Borsotti, Mariella Brenna, Anna Chiara Cimoli, Lars De Jaegher, Maria Camilla De Palma, Hugues De Varine, Maria De Waele, Nélia Dias, Simone Eick, Fabienne Galangau Quérat, Sarah Gamaire, Jan Gerchow, Marc-Olivier Gonset, Klas Grinell, Laurence Isnard, Marie-Paule Jungblut, Galitt Kenan, Francesca Lanz, José María Lanzarote Guiral, Vito Lattanzi, Jack Lohman, Carolina Martinelli, Frauke Miera, Elena Montanari, Chantal Mouffe, Judith Pargamin, Giovanni Pinna, Camilla Pagani, Clelia Pozzi, Paolo Rosa, Anna Seiderer

Effect of Hyperbaric Storage at Room Temperature on the Activity of Polyphenoloxidase in Model Systems and Fresh Apple Juice

The effect of hyperbaric storage (HS) on polyphenoloxidase activity (PPO) was studied in model solutions and apple juice. Model solutions containing increasing amounts of mushroom (Agaricus bisporus) PPO (up to 26 U) were stored at room temperature at pressure up to 200 MPa. During HS, samples were assessed for residual PPO activity. The enzyme was completely inactivated according to a first-order kinetic model that was used to calculate PPO decimal reduction time (Dp) and pressure sensitivity (zp = 140.8 MPa) in diluted model solutions (2 U PPO). The increase in enzyme concentration (6–26 U) nullified the effect of HS, probably due to protein structure stabilization by self-crowding. The application of HS at 100 and 200 MPa to apple juice promoted a decrease in total bacteria, lactic acid bacteria, yeasts, and molds. These changes occurred in concomitance with the inactivation of PPO (zp = 227.3 MPa). At 200 MPa, PPO inactivation followed a biphasic first-order kinetic, suggesting the presence of PPO isozymes with different pressure sensitivity. The inactivation of PPO was observed to occur more rapidly with increasing storage pressure and led to the maintenance of the original bright juice color. This study proves the capability of HS to control enzyme-related quality decay in fruit juices and, potentially, in many other food matrices suffering enzymatic alteration

From secular stagnation to robocalypse? Implications of demographic and technological changes

Los cambios demográficos y una nueva ola de innovación y de automatización son dos de las principales tendencias estructurales que configurarán el escenario macroeconómico en las próximas décadas. Utilizando un modelo de equilibrio general con una sencilla estructura demográfica, investigamos los principales mecanismos de transmisión por los cuales la demografía y la tecnología afectan al crecimiento económico. Debido a una disyuntiva entre innovación y automatización, una menor fertilidad y el envejecimiento poblacional generan una reducción en el crecimiento del PIB per cápita y en la participación de los salarios en el PIB. Durante la transición demográfica, la medida en la que el crecimiento y la participación de los factores se ven afectados depende de las diferentes configuraciones del mercado laboral y de escenarios para la integración de robots en la actividad económica.Demographic change and automation are two main structural trends shaping the macroeconomy in the next decades. We present a general equilibrium model with a tractable life-cycle structure that allows the investigation of the main transmission mechanisms by which demography and technology affect economic growth. Due to a trade-off between innovation and automation, lower fertility and population ageing lead to reductions in GDP per capita growth and the labour income share. During the demographic transition, the extent growth and factor shares are affected depends on alternative labour market configurations and scenarios for the integration of robots in economic activity
