Quantifying the Impact of Structural Reforms [PDF]
SSRN Electronic Journal, 2006 We estimate a dynamic, intertemporal optimisation model that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness that compares well with standard indicators of product and labour market

The structural impact of DNA mismatches [PDF]
Nucleic Acids Research, 2015 The structure and dynamics of all the transversion and transition mismatches in three different DNA environments have been characterized by molecular dynamics simulations and NMR spectroscopy. We found that the presence of mismatches produced significant local structural alterations, especially in the case of purine transversions.
