This paper uses approximate linear programming (ALP) to compute average cost bounds for queueing network control problems. Like most approximate dynamic programming (ADP) methods, ALP approximates the differential cost by a linear form. New types of approximating functions are identified that offer more accuracy than previous ALP studies or other performance bound methods. The structure of the infinite constraint set is exploited to reduce it to a more manageable set. When needed, constraint sampling and truncation methods are also developed. Numerical experiments show that the LPs using quadratic approximating functions can be easily solved on examples with up to 17 buffers. Using additional functions reduced the error to 1-5% at the cost of larger LPs. These ALPs were solved for systems with up to 6-11 buffers, depending on the functions used. The method computes bounds much faster than value iteration. It also gives some insights into policies. The ALPs do not scale to very large problems, but they offer more accurate bounds than other methods and the simplicity of just solving an LP. © 2015 Elsevier Ltd. All rights reserved. Source

Brightness measurements made during 1963-1965 and 1991-2009 are used in constructing models of the brightness of the Saturn system in the Johnson B, V, R and I system. The models cover nearly the full range of phase angles and ring opening angles visible from the Earth and are believed to be accurate to 0.03-0.05 magnitudes. A U-filter model is also selected which covers ring opening angles of between 4° and 14° The model is the first such one that treats the light from the rings as a function of the saturnicentric latitude from the Earth and Sun in a way that is consistent with observations and theoretical considerations. Six conclusions of this work are: (1) the Saturn system brightens as the solar phase angle decreases, (2) the Saturn system has an opposition surge, (3) the opposition surge increases as the ring opening angle increases, (4) the solar phase angle coefficient increases as the ring opening angle increases, (5) the B-V, V-R and R-I color indexes change by up to 0.2 magnitudes as Saturn orbits the Sun and (6) the V-filter model in this report is a better fit to the 1963-2009 data than the one proposed by Harris (Harris, D.L.

We propose a mesoscopic particle-exchange heat engine realized via coupled quantum dots. The engine is able to extract work from a bosonic reservoir and can be used as a refrigerator. The electric current is derived from a master-equation method and is readdressed under a thermodynamic context. The quantum-mechanical result is found to be consistent with thermodynamic analysis. © 2011 American Physical Society. Source

Are children better than adults in acquiring new skills ('how-to' knowledge) because of a difference in skill memory consolidation? Here we tested the proposal that, as opposed to adults, children's memories for newly acquired skills are immune to interference by subsequent experience. The establishment of long-term memory for a trained movement sequence in adults requires a phase of memory consolidation. This results in substantial delayed, 'offline', performance gains, which nevertheless remain susceptible to interference by subsequent competing motor experience for several hours after training, unless sleep is afforded in the interval. Here we compared the gains attained overnight (delayed gains) by 9-year-olds and adults after training on a novel finger-to-thumb movement sequence, with and without subsequent interference by repeating a different movement sequence. Our results show that, in 9-year-olds, but not in adults, an interval of 15 min. between the training session and interfering experience sufficed to ensure the expression of delayed, consolidation phase, gains. Nevertheless, in the 9-year-olds, as well as in adults, the gains attained with no interference were significantly larger. Altogether, our results show that while the behavioral expressions of childhood and adult consolidation processes are similar, procedural memory stabilizes, in the waking state, at a much faster rate in children. We propose that, in children, rapid stabilization is a mechanism whereby the constraints on consolidating new experiences into long-term procedural memory are relaxed at the cost of selectivity. © 2014 John Wiley & Sons Ltd.

Abstract This paper investigates the matching between banks and firms in the loan market. We estimate a many-to-one two-sided matching model using the Fox (2010) matching maximum score estimator. Using data on the U.S. loan market from 2000 to 2003, we find evidence of positive assortative matching of sizes. Moreover, we show that banks and firms prefer partners that are geographically closer, giving support to the importance of physical proximity for information gathering and expertise sharing. We also show that banks and firms prefer partners with whom they had prior loans, indicating that prior loan relationship plays an important role in the selection of current partners. © 2013 Elsevier B.V.
