How accurately can we measure weak gravitational shear?

How accurately can we measure the W cross section?

We study the QCD sources of systematic uncertainties in the experimental extraction of the W cross section at hadron colliders. The uncertainties appear in the evaluation of the detector acceptances used to convert the number of observed events into a total production cross section. We consider the effect of NLO corrections, as well as of the inclusion of parton showers, and evaluate the impact...

How can we begin to measure recovery?

BACKGROUND There is a lack of consensus in the addiction treatment literature regarding the definition of substance abuse "recovery". METHODS This study utilized a review of the literature together with a participatory research design to construct a conceptual model of recovery from the perspectives of addiction treatment professionals, those recovering from addictions, and researchers. RES...

How can we measure machine translation quality?

In this opinion paper, we describe our research work on machine translation evaluation approaches that include mechanisms for human feedback and are designed to allow partial adaptation of the translation models which are being evaluated. While there exists a plethora of different automatic evaluation metrics for machine translation, their output in terms of scores, distances, etc. quite often ...

How can we enhance the value of laboratory tests?

Today, the pressures on the healthcare systems for the controlling of the costs are extreme and all sectors try to demonstrate the value of their services by justifying the activities and expenditures so the value can be describe in terms like quality, efficiency, effectiveness, patient satisfaction, cost effectiveness .The value of the lab testing is generally directed to their costs and the c...
