This note proposes a new get-rich-quick scheme that involves trading in a stock with a continuous but not constant price path. The existence of such a scheme, whose practical value is tempered by its use of the Axiom of Choice, shows that imposing regularity conditions (such as measurability) is essential even in the foundations of game-theoretic probability. . . . these results do not give a p...

This paper applies quantal response equilibrium (QRE) models (McKelvey and Palfrey, 1995, Games and Economic Behavior) to ultimatum bargaining games. When the strategy space is discrete, as the noise vanishes, the QRE of the normal-form representation converges to a Nash equilibrium in which an equilibrium o er is between 0 and a half of the pie while the QRE of the extensive-form representatio...

Training agents in a virtual crowd to achieve a task can be accomplished by allowing the agents to learn by trial-and-error and by sharing information with other agents. Since sharing enables agents to potentially reach optimal behavior more quickly, what type of sharing is best to use to achieve the quickest learning times? This paper categorizes sharing into three categories: realistic, unrea...

It is demonstrated that unique and simple analytical functions are justified for the atomic charge dependences q of the T (T = Al, P) and O atoms of aluminophosphates (AlPOs) using DFT calculations with several basis sets, starting from STO-3G to 3-21G and 6-21G**. Three internal (bonds, angles, ...) coordinates for the charge dependences of the T atoms and four coordinates for the O are suffic...

An 18-week-old umbrella cockatoo presented for continuous vocalization and one episode of regurgitation. The bird had been purchased 3 weeks before presentation and was the first large pet bird owned by this family. The cockatoo was fed a commercial baby bird formula that the owners were heating in the microwave before feeding. The owner had been instructed on formula feeding by the pet store p...

Abstract A simplified model of the bird skeleton along with elongation parameters for the flight feathers is used to explore the diversity of bird shapes. Varying the small number of parameters simulates a wide range of observed bird silhouettes. The model may serve to examine developmental factors involved in these forms, help museum curators develop computational approaches to bird morphometr...

Auditory expertise has mostly been studied in relation to musical processing, but expert auditory processing can also involve nonmusical auditory stimuli, such as birdsongs in bird experts. In this study, the neural correlates of bird expertise were investigated by using electroencephalography to measure auditory-evoked potentials in bird experts and novices. Auditory stimuli in three categorie...
