In a repeated game with perfect monitoring, correlation among a group of players may evolve in the common course of play (online correlation). Such a correlation may be concealed from a boundedly rational player. The feasibility of such online concealed correlation'' is quantified by the individually rational payoff of the boundedly rational player. We show that ``strong'' players, i.e., players whose strategic complexity is less stringently bounded, can orchestrate online correlation of the actions of ``weak'' players, in a manner that is concealed from an opponent of ``intermediate'' strength. The result is illustrated in two models, each captures another aspect of bounded rationality. In the first, players use bounded recall strategies. In the second, players use strategies that are implementable by finite automata.

We study a repeated game in which one player, the prophet, acquires more information than another player, the follower, about the play that is going to be played. We characterize the optimal amount of information that can be transmitted online by the prophet to the follower, and provide applications to repeated games played by finite automata, and by players with bounded recall.

The dynamics of a chain of vibrational bonds which develop a classical solitary compression wave is simulated. A converged fully correlated quantum mechanical calculation is compared with a time dependent mean field approach (TDSCF) and with a classical simulation. The dynamics were all generated from the same Hamiltonian. The TDSCF and classical calculations show a fully developed solitary wave with the expected dependence of group velocity on amplitude. The full quantum calculations show a solitary-like wave which propagates for a while but then degrades. The robustness of the compression wave depends on the initial preparation. Evidence of partial recurrence of the wave has also been observed. (C) 2003 American Institute of Physics.
This paper develops a political economy model that is consistent with the fact that democracies have a preference for increasing marginal tax rates on income. We present a model in which there is an exogenous set of political parties with preferences over the set of admissible tax schedules. This set contains virtually any increasing and piecewise linear continuous function. Each party decides whether or not to present a candidate for election. There is a fixed cost of running. The elected candidate implements one of her preferred tax policies. Our main results provide conditions under which a Strong Nash Equilibrium exists, and a tax schedule with increasing marginal tax rates is implemented in some Nash Equilibria and in any Strong Nash Equilibrium.
Rheol. properties of the interfacial layers of gelatins chem. modified with N-hydroxysuccinimide ester of caprylic acid (the degree of modification is 10, 30, and 85%) are studied. Interfacial layers are spontaneously formed at the aq. gelatin soln.-toluene interface. Rheol. characteristics (yield strength, modulus of elastic deformation, Schwedoff and Bingham viscosities) increase in proportion to the degree of modification (hydrophobization) of gelatin.

Stabilized concd. citrate-reduced silver nanocolloids for use as pigments in ink-jet inks were prepd. CM-cellulose was used as a polymeric stabilizer providing both electrostatic and steric stabilization. X-ray diffraction pattern, optical properties (UV-visible spectroscopy), size (TEM and dynamic light scattering), and zeta potentials of the nanoparticles were studied. It was shown that the product is silver with cubic symmetry. Absorption spectra are characterized, as a rule, by asym. absorption bands with maxima at 417-440 nm and shoulders at 350-352 and 380-382 nm. TEM images of unstabilized and stabilized colloids indicate the formation of nanoparticles of different shapes (spheres, hexagons, cubes, and rods) with rather wide size distribution in the range from several nanometers (spheres) up to several hundreds of nanometers (rods). CMC was found to be an effective stabilizer of silver nanoparticles, and the av. particle size at CMC concns. from 0.025 to 0.2 wt. % does not exceed 50 nm. Both unstabilized and stabilized silver nanoparticles display neg. zeta potentials in the pH range from 2 to 9; the maximal neg. values are obsd. at pH 6-8 (-27 ± 5 mV for unstabilized and -33 ± 5 mV for CMC-stabilized colloids, resp.). Concd. dispersions of silver nanoparticles (1.1 wt. % of silver), which were stable for at least 7 mo, were prepd. by exhausted lyophilization of the freshly prepd. colloids followed by redispersion. These nanoparticles in the presence of proper wetting agent, such as Disperbyk, can be used as pigments in ink-jet ink formulations for printing on various substrates (paper, glass, and transparencies). The stabilizing agent, CM-cellulose, also acts as a binder, providing good adhesion of ink to the substrates. [on SciFinder(R)]
