Multiagent resource allocation defines the issue of having to distribute a set of resources among a set of agents, aiming at a fair and efficient allocation. Resource allocation procedures can be evaluated with regard to properties such as budget balance and strategy-proofness. Designing a budget-balanced and strategy-proof allocation procedure that always provides a fair (namely, envyfree) and...

This paper presents the results of a set of experiments performed to test the properties of a bargaining mechanism (called the sealed-bid mechanism) used to structure bargaining under incomplete information. Our results indicate that the mechanism performs quite well. When using it, experimental subjects are able to capture a large portion of the potential gains from trade. In addition, the beh...

The aim of this in vitro study is to compare the microleakage of a root perforation sealed with MTA (mineral trioxide aggregate) (group M) to that sealed with MTA following Er:YAG laser irradiation (group ML). Forty-two recently extracted human monoroot teeth were used. Two cavities were prepared on each root surface. Randomly, on each root, the exposed dentine of one cavity was irradiated prio...

Seventy-one caries-free human occlusal fissures were used for this study. Twenty-two fissures were sealed with a glass ionomer sealant (Fuji Ionomer Type III--G-C Dental Industrial Corp., Tokyo, Japan), 24 were widened with a diamond bur and sealed with the glass ionomer sealant, and 25 were left unsealed. After one week, the sealants were removed as completely as possible with a probe. All fis...

Reproductive boll weevil populations are typically identified by the presence of a frass seal and protuberance at the oviposition site in cotton squares. However, despite the occurrence of other oviposition puncture seal types and their use in previous fecundity studies, the relationship of these respective puncture seal types and oviposition has not been clearly examined. In this study, newly ...
