This work presents a lookahead-based exploration strategy for a model-based learning agent that enables exploration of the opponent’s behavior during interaction in a multi-agent system. Instead of holding one model, the model-based agent maintains a mixed opponent model, a distribution over a set of models that reflects its uncertainty about the opponent’s strategy. Every action is evaluated a...

This paper investigates the effect of founders’ professional-education background on the adoption of an open-science technology strategy, using a sample of 512 young biotechnology firms. After controlling for founders’ prior work experience and other organizational and environmental factors, I find that firms with proportionally more Ph.D.-holding entrepreneurs on the founding team have a highe...

A growing literature suggests that even in the absence of any ability to predict returns, holding options on the benchmarks or trading frequently can generate positive alpha. The ratio of alpha to its tracking error appraises a fund’s performance. This paper derives the performance-maximizing strategy, which turns out to be a variant of a buywrite strategy, and the least upper bound on such per...

This paper investigates the effect of founder professional education background on the adoption of the open-science technology management strategy by a sample of 512 young biotechnology firms. One major finding of the paper is that after controlling for founder prior work experience and other organizational and environmental factors, biotechnology firms with proportionally more Ph.D.-holding en...

BACKGROUND Breath-holding attacks are common during childhood. Iron supplementation has been claimed to reduce the frequency or severity, or both, of breath-holding attacks in children. OBJECTIVES To assess the effect of iron supplementation on the frequency and severity of breath-holding attacks in children. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CE...

This paper addresses the integrated scheduling and lot-sizing problem in a manufacturing environment which produces complex assemblies. Given the due-dates of the end items, the objective is to minimize the cumulative lead time of the production schedule (total makespan) and reduce set-up and inventory holding costs. A JIT production strategy is adopted in which production is scheduled as late ...

To provide an acceptable call blocking probability in circuit-switched cellular networks, such as the Advanced Mobile Phone System (AMPS) networks, a significant fraction of the channel capacity in each cell is normally unused. This “free” capacity can be effectively used for packet data transmissions that yield to voice traffic when necessary. Cellular Digital Packet Data (CDPD) is a packet-sw...

cross docking is a logistic strategy that plays the role of a middle knot in distribution network in the provision process. in logistic part, inventory holding is considered as an important matter in managing costs. not only cross docking reduces the inventory holding cost, but it also reduces the cost of collecting received orders, transportation and duration of sending. the products, which ar...

Locomotor activity by diving marine mammals is accomplished while breath-holding and often exceeds predicted aerobic capacities. Video sequences of freely diving seals and whales wearing submersible cameras reveal a behavioral strategy that improves energetic efficiency in these animals. Prolonged gliding (greater than 78% descent duration) occurred during dives exceeding 80 meters in depth. Gl...
