Quantum dynamical maps are defined and studied for quantum statistical physics based on Orlicz *** complements earl.e. work[26]where we made a strong case for the assertion that statistical physics of regular systems should properly be based on the pair of Orlicz spaces(lcosh-1,l log(l+1)),since this framework gives a better description of regular observables,and also allows for a well-defined entropy *** the present paper we"complete"the picture by addressing the issue of the dynamics of such a system,as described by a Markov semigroup corresponding to some Dirichlet form(see[4,13,14]).Specifically,we show that even in the most general non-commutative contexts,completely positive Markov maps satisfying a natural Det ailed Balance condition canonically admit an action on a large class of quantum Orlicz *** is achieved by the development of a new interpolation strategy for extending the action of such maps to the appropriate intermediate spaces of the pair(l∞,l1).As a consequence,we obtain that completely positive quantum Markov dynamics naturally extends to the context proposed in[26].

A new anurognathid pterosaur specimen from the Middle Jurassic Tiaojishan Formation of Qinglong, northern Hebie Province is described. The new specimen is referred to Dendrorhynchoides, based on the general morphology of the skeleton, but it represents a new species, named here as Dendrorhynchoides mutoudengensis sp. nov.. It is characterized by the presence of short, robust and straight teeth, and bearing wing metacarpal approximately 40% of the length of humerus. The new specimen provides further osteological information for anurognathid pterosaurs, especially the presence of a relatively elongate tail.

Rana Gruber AS is a mining company situated in northern Norway, just south of the artic circle. The hematite/magnetite ore is low grade, steeply dipping and intensively fol.e.. The company excavates about 1.2 million tonnes of ore annually. The mining method is sublevel stoping. The final products are a hematite concentrate and different magnetite-products. The bits and bytes based methods and systems implemented for production planning and controlling are presented in the paper. Focus is on geological modelling, utilisation of variations in the deposit and associated uncertainty accumulating throughout the val.e.chain. The methods and systems enable the mining department in greater extent than before, to deliver fragmented ore according to the specifications given by the processing plant.

The microcracking behaviour of TiAl-based alloys with the duplex and fully-lamellar microstructures was studied during compression. It was found that the fracture invol.e. propagation of the existing microcracks and development of more new nuclei, instead of being a nucleation-control.e. event. The lamellar interfaces, especially those having an angle of about 0 similar to 30 degrees C to the loading axis, were found to be the favourable nucleation sites. Microcrack nucleation is likely to be initiated by tensile normal stress concentrated on the lamellar interfaces.

This paper introduces the notion of Tokamak Magneto-Hydrodynamics （TMHD）, which explicitly reflects the anisotropy of a high temperature tokamak plasma. The set of TMHD equations is formulated for simulation of macroscopic plasma dynamics and disruptions in tokamaks. Free from the Courant restriction on the time step, this set of equations is adequate to plasma dynamics with realistic parameters of high performance plasmas and does not require any extension of the MHD plasma model. At the same time, TMHD requires the use of magnetic field aligned numerical grids. examples of their use in 2-dimensional cases of tokamak equilibria and dynamics of the wall touching kink mode are presented. For the 3-dimensional case of an ergodic magnetic field, this paper introduces the reference magnetic coordinates as a practical algorithm for generating adaptive grids for TMHD.
