Developing laser processes for industrial applications is a challenging and laborious task. Conventional controllers scan systems lack the ability to predict actual path of beam on workpiece, making extensive trial-and-error testing different parameters delay settings necessary in order achieve satisfactory results. Finding balance between accuracy achieved throughput typically compromise, vari...

We examine the relationship between climate policy uncertainty ( CPU ) and stock market volatility using GARCH-MIDAS framework to accommodate variables in their available frequencies thereby circumventing information loss associated with data aggregation or splicing. find that significantly responds we further document improved forecast economic gains of observing relative ignoring it.

BACKGROUND Accumulating evidence suggests that members of society prefer some QALY gains over others. In this paper, we explore the notion of acceptable health as a reference point in assessing the value of health gains. The value of health benefits may be assessed in terms of their position relative to this reference level, benefits above the level of acceptable health being valued differently...

Coronagraphic imaging reduces PSF wings by 0.6 mag using Keck adaptive optics in the NIR, and 1.5 mag using ACS in the visible. The PSF suppression attained is roughly comparable for the two instruments. Future work should test the relative contrast gains from PSF subtractions.

We hypothesize that sharing a birthday is sucient to create a unit relationship. Two studies demonstrated that individuals cooperated more in a prisoners dilemma game when their (®ctitious) opponent shared their birthday. They also reacted more negatively to betrayal and were less sensitive to relative gains for self versus other. # 1998 John Wiley & Sons, Ltd.

Word alignments that violate syntactic correspondences interfere with the extraction of string-to-tree transducer rules for syntaxbased machine translation. We present an algorithm for identifying and deleting incorrect word alignment links, using features of the extracted rules. We obtain gains in both alignment quality and translation quality in Chinese-English and Arabic-English translation ...
