Tool for robust stochastic parsing using optimal maximum coverage

This report presents a robust syntactic parser that is able to return a "correct" derivation tree even if the grammar cannot generate the input sentence. The following two step solution is prop osed: the finest corresponding most probable optimal maximum coverage is generated first, then the trees from this coverage are glued into one resulting tree. We discuss the implementation of this method with the SLP toolkit and libkp library

Multicriteria decision analysis to support HTA agencies : benefits, limitations, and the way forward

Objective Recent years have witnessed an increased interest in the use of multicriteria decision analysis (MCDA) to support health technology assessment (HTA) agencies for setting healthcare priorities. However, its implementation to date has been criticized for being “entirely mechanistic,” ignoring opportunity costs, and not following best practice guidelines. This article provides guidance on the use of MCDA in this context. Methods The present study was based on a systematic review and consensus development. We developed a typology of MCDA studies and good implementation practice. We reviewed 37 studies over the period 1990 to 2018 on their compliance with good practice and developed recommendations. We reached consensus among authors over the course of several review rounds. Results We identified 3 MCDA study types: qualitative MCDA, quantitative MCDA, and MCDA with decision rules. The types perform differently in terms of quality, consistency, and transparency of recommendations on healthcare priorities. We advise HTA agencies to always include a deliberative component. Agencies should, at a minimum, undertake qualitative MCDA. The use of quantitative MCDA has additional benefits but also poses design challenges. MCDA with decision rules, used by HTA agencies in The Netherlands and the United Kingdom and typically referred to as structured deliberation, has the potential to further improve the formulation of recommendations but has not yet been subjected to broad experimentation and evaluation. Conclusion MCDA holds large potential to support HTA agencies in setting healthcare priorities, but its implementation needs to be improved

Terahertz sensing of supercooled glycerol using a 1D photonic crystal

International audienceWe have developed a 1D photonic crystal that can be used for sensing purposes at terahertz frequencies and which requires less then one microliter of sample material. Using this sensor we have obtained temperature dependent measurements of refractive index and extinction coefficient of glycerol in the temperature range 100 - 294 K
