Cosmic ray studies with the L3 detector at LEP
No full textThe L3 detector at the LEP accelerator offers good prospects for the study of high energy cosmic ray muons. Efforts made by the collaboration to provide a new tool for cosmic ray detection are described. The experimental status and the physics perspectives are reviewed

No full textInnovation and information acquisition under time inconsistency and uncertainty
No full textThis paper analyzes the impact of hyperbolic discounting preferences on theagent's information acquisition decision who wants to undertake a potentialdangerous activity for human health or the environment. We find that belowcertain discount rate threshold, an agent prefers ignoring information andcontinuing his project. On the other hand, above this threshold, it is optimal forhim to acquire information, and the investment for acquiring the information isincreasing with the discount rate. We then conclude that hyperbolic discountingpreferences limit the information acquisition. Moreover, we explain that the lackof self-control induced by hyperbolic discounting preferences also restraints theinformation acquisition. Finally, we analyze the efficiency of the strict liabilityrule and the negligence rule to motivate the agent to acquire information.Innovation, information acquisition, uncertainty, self-control, time inconsistency,liability rules
