Elliptic flow from event-by-event hydrodynamics

We present an event-by-event hydrodynamical framework which takes into account the initial density fluctuations arising from a Monte Carlo Glauber model. The elliptic flow is calculated with the event plane method and a one-to-one comparison with the measured event plane $v_2$ is made. Both the centrality- and $p_T$-dependence of the $v_2$ are remarkably well reproduced. We also find that the participant plane is a quite good approximation for the event plane.Comment: 4 pages, 3 figures. Talk given at Quark Matter 2011, 22-28 May 2011, Annecy, Franc

Designing coordination contracts to support efficient flow-scheduling in pork chain

Risk management and efficient, well coordinated, flow-scheduling have an increasingly important role in the competitive pork production networks. Changes in input and output prices have resulted in distortions in the Finnish pig markets during the last years. The goal of this study is to estimate how different price or quantity-fixing contracts affect the values of pig and sow space unit under price risk. The values are estimated with two stochastic dynamic programming models. The results suggest that a contract which is able to control both the pattern of changes in piglet prices and the option to suspend production temporarily has a value and it can help to improve the competitiveness of the pig sector. However, it is feasible to have incentives towards the contract commitment when market situation upon accepting the commitment is favourable.vo

Abelian and Non-Abelian Induced Parity Breaking Terms at Finite Temperature

We compute the exact canonically induced parity breaking part of the effective action for 2+1 massive fermions in particular Abelian and non Abelian gauge field backgrounds. The method of computation resorts to the chiral anomaly of the dimensionally reduced theory.Comment: 13 pages, RevTeX, no figure
