WR22 = HD 92740 is a bright (V 6.4 $mag$), intrinsically luminous, double-line WN7h + O9III-V binary exhibiting one sharp 8\% deep eclipse near periastron in its elliptical (e 0.6) 80-day orbit, when the WR-star passes front of O star, with no secondary eclipse. We apply two models (L96, A13) to probe optical space-based light curves from {\em BRITE-Constellation}, including three separate, com...

The paper considers the conjecture that forecasts from preferred economic models or theories d-separate forecasts from less preferred models or theories from the actual realization of the variable for which a scientific explanation is sought. Dseparation provides a succinct notion to represent forecast dominance of one set of forecasts over another; it provides, as well, a criterion for model p...

In order to address the question whether Hayek might have been an Agent-based Computational Economist (ACE) avant-la-lettre, we consider an ACE model concerning the phenomenon of information contagion. Alongside increasing returns, network externalities, and information cascades, information contagion has been presented in the literature as an explanation for particular patterns of macrobehavio...

The Net Present Value maximizing model has a respectable ancestry and is considered by most scholars a theoretically sound decision model. In real-life applications, decision makers use the NPV rule, but apply a subjectively determined hurdle rate, as opposed to the “correct” opportunity cost of capital. According to a heuristics-and-biases-program approach, this implies that the hurdle-rate ru...

At present, with the progress and innovation of technology, the radar communication dual function wave has become a hot research at home and abroad. Excellent integrated waveform can make full use resources of combat platform, reduce the size of equipment, and realize the actual functionality of the reality of the battle-field without affecting the radar communication function. The MSK-LFM dual...
