Motivated by ideas from the consistent histories approach to quantum mechanics, we examine a simple model of hydrodynamic coarse graining for a scalar field. It consists in averaging the field over spatial regions of size L and constructing the evolution equations for the coarse grained quantities, identifying dissipation and noise.

We prove a version of the Fundamental Theorem of Asset Pricing, which applies to Kabanov’s approach to foreign exchange markets under transaction costs. The financial market is modelled by a d × d matrix-valued stochastic process (Σt)t=0 specifying the mutual bid and ask prices between d assets. We introduce the notion of “robust no arbitrage”, which is a version of the no arbitrage concept, ro...

We use a λΦ4 scalar quantum field theory to illustrate a new approach to the study of quantum to classical transition. In this approach, the decoherence functional is employed to assign probabilities to consistent histories defined in terms of correlations among the fields at separate points, rather than the field itself. We present expressions for the quantum amplitudes associated with such hi...

Introduction In “The Ethics of Dynamic Pricing,” Faruqui (Faruqui 2010) lays out a case for improved efficiency in using dynamic prices for retail electricity tariffs and addresses various issues about the distributional effects of alternative pricing mechanisms. The principal contrast is between flat or nearly constant energy prices and time-varying prices that reflect more closely the margina...

Effect of electronegative substituents on ring opening of [2.2.2]propellane was examined by quantum chemical calculations at CASSCF and CASPT2 level of theory. Comparison of the results with those obtained with MR-AQCC calculations indicated that calculations beyond CASSCF level were needed for reliable description of the process. Calculations show a strong effect of fluorination on the central...

Building on a new definition and characterization of probabilistic event structures, a general definition of distributed probabilistic strategies is proposed. Probabilistic strategies are shown to compose, with probabilistic copy-cat strategies as identities. A higher-order probabilistic process language reminiscent of Milner’s CCS is interpreted within probabilistic strategies. W.r.t. a new de...

Density functional calculations have been performed on the excited states of Cr(CO)6. In contrast to the generally accepted assignment of the spectrum by Gray and Beach1,2 but in agreement with recent CASSCF/CASPT2 calculations by Pierloot et al.3 we find the low-intensity absorption at the low-energy side of the first charge-transfer (CT) band not to be due to ligand-field (LF) excited states,...

Many theorists would agree that, had it not been for the unproven unification of 802.11b and IPv7, the simulation of I/O automata might never have occurred. After years of essential research into superblocks, we demonstrate the study of consistent hashing. In this work we use flexible methodologies to argue that Boolean logic and cache coherence can collude to address this quandary. This follow...
