Antigen carbohydrate 125 and brain natriuretic peptide serial measurements for risk stratification following an episode of acute heart failure.

2010

Abstract Background The prognostic utility of combining serial measurements of brain natriuretic peptide (BNP) and antigen carbohydrate 125 (CA125) is largely unknown. The aim of this work is to assess the prognostic utility of serial measurements of BNP, CA125, and their optimal combination for predicting long-term mortality, following a hospitalization for acute heart failure (AHF). Methods and results We analyzed 293 consecutive patients admitted with AHF where CA125 and BNP were measured at discharge (T1) and at the first ambulatory visit (T2: median 31days after discharge). Biomarkers were evaluated as snapshot determinations or as serial changes in absolute, relative or categorical ch…

Bayesian methods in cost-effectiveness studies: objectivity, computation and other relevant aspects.

2009

In a probabilistic sensitivity analysis (PSA) of a cost-effectiveness (CE) study, the unknown parameters are considered as random variables. A crucial question is what probabilistic distribution is suitable for synthesizing the available information (mainly data from clinical trials) about these parameters. In this context, the important role of Bayesian methodology has been recognized, where the parameters are of a random nature. We explore, in the context of CE analyses, how formal objective Bayesian methods can be implemented. We fully illustrate the methodology using two CE problems that frequently appear in the CE literature. The results are compared with those obtained with other popu…

A Short Presentation of LucSim

2017

LucSim is a cellular automata (CA) dedicated to geographical analysis and spatial simulation for researchers and advanced planning institutes, providing user-friendly software in order to analyze and simulate land use changes and dynamics. Two complementary models are integrated in the CA: (1) a Markov Chain used to calculate transition matrices from a date to another, and (2) a Decision Tree able to automatically determine a set of transition rules to be applied on land use data. LucSim includes GIS compatibility functions allowing to display ESRI shapefiles and is based on raster georeferenced images saved in TIF format. It was mostly applied on French urban case studies.

Locality-Sensitive Hashing for Massive String-Based Ontology Matching

2014

This paper reports initial research results related to the use of locality-sensitive hashing (LSH) for string-based matching of big ontologies. Two ways of transforming the matching problem into a LSH problem are proposed and experimental results are reported. The performed experiments show that using LSH for ontology matching could lead to a very fast matching process. The quality of the alignment achieved in these experiments is comparable to state-of-the-art matchers, but much faster. Further research is needed to find out whether the use of different metrics or specific hardware would improve the results. peerReviewed
