We discuss the fate of initial states of the cat type for the damped harmonic oscillator, mostly employing a linear version of the stochastic Schrödinger equation. We also comment on how such cat states might be prepared and on the relation of single realizations of the noise to single runs of experiments. Typeset using REVTEX 1

We study in detail the system of D6 branes and euclidean D2-brane instantons intersecting at angles in type IIA string theory. We find that in the absence of orientifolds the system does not contribute to the low energy superpotential, in agreement with expectations based on effective field theory arguments. We also comment on the implications of our results for dual string theory pictures.

The gauge-invariant Chern-Simons-type Lorentzand CPT-breaking term is here re-assessed and issues like causality, unitarity, spontaneous gauge-symmetry breaking are investigated. Moreover, we obtain a minimal extension of such a system to a supersymmetric environment. We comment on resulting peculiar self-couplings for the gauge sector, as well as on background contribution for gaugino masses.

Epithelial adhesive cell-to-cell contacts contain large, plasma membrane-spanning multiprotein aggregates that perform vital structural and signaling functions. Three prominent adhesive contacts are the tight junction, adherens junction, and the desmosome. Each junction type has unique cellular functions and a complex molecular composition. In this review, we comment on recent and exciting adva...

The first part of this text comes back on the standard economic viewpoint on expectational coordination, a viewpoint that the recent events have challenged. The second part reviews the existing directions for a critical assessment of the rational expectations hypothesis. The third part shows how such a critical assessment, along the lines of the socalled “eductive” learning approach, radically ...

We thank the referee for the comments. In general the reviews have lead to a substantial amount of improvements and refinements thus better specifying the instrumentation and its performance. Concerning the question “Should CARIBIC be managed as a resource to the community similar to a satellite, or should itĚ.” we note that this is a complex discussion. (if the status ”as a resource” would mea...

Every time we meet with our investment advisors, we go over the same things. We look at the amount of cash contributed during that quarter, the ratio of equities, debt, derivatives, commodities and other financial instruments. We explore the distribution of assets among economic sectors and geography. Finally, we get to the numbers that concern us most, the bottom line rate of return net of fee...
