We analyze the risk-taking behavior of political candidates who are uncertain about the values voters assign to various policy platforms. We show that the majoritarian and proportional electoral systems lead to different outcomes. The proportional system penalizes risky platforms more than the winner-take-all system. Since candidates choose “safer” platforms, in the proportional system voters f...

Viability of Bordetella pertussis was preserved when glycerol broth suspensions were quick frozen and stored at -70 C for as long as 45 months.

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...

Sildenafil citrate is one of the most effective agents for treatment of erectile dysfunction which acts by inhibiting the cGMP-specific phosphodiesterase type 5. Extensive research work is focused on flash release dosage forms and especially fast dissolving films are successful to attract pharma-industry due to ease of preparation and opportunity to extend patent life. Films are widely acceptab...
