I provide a full characterization of the set of absolutely expedient learning rules introduced in Börgers et al. . The expected change in the expected payoff can be written as a quadratic form on the vector of relative expected payoffs of the strategies. This permits use of standard linear algebra arguments to provide a characterization in terms of the matrix defining this quadratic form.
Some physical factors affecting the relative advantages of organic and inorganic electroluminescence are discussed. Especial attention is given to carrier transport, the strength of radiative transitions and carrier-carrier interactions. Speculations Air Max 2014 Bleu
are made concerning devices in which organic electroluminescence could compete effectively with existing technologies.
Necessary and sufficient conditions for transforming into the Wiener process a one-dimensional diffusion process descibed by a Kolmogorov or by a Langevin equation are provided, and the transformation is determined. The relationship of these conditions with the criterion due to Cherkasov is exploited. A few examples are discussed.
We describe Air Vortex Femme
a nonlinear interferometric setup to perform a complete optical Bell measurement, i.e. to unambiguously discriminate the four polarization-entangled EPR-Bell photon pairs. The scheme is robust against detector inefficiency.
