We carried out different research projects by using our expertise in the field of the study of equilibria in solution, the synthesis and the NMR characterisation of cyclodextrin derivatives, capillary electrophoresis techniques, and electrospray mass spectrometry for the detection and the characterisation of the involved analytes. The most of our work concerns the separation science, and partic...

This paper establishes a new fact about the compositional changes in the pool of unemployed over the U.S. business cycle. Using micro-data from the Current Population Survey for the years 1962-2012, it documents that in recessions the pool of unemployed shifts towards workers with high wages in their previous job. These shifts are associated with both observed and unobserved factors in the wage...

Efficient liquid-liquid separations are an integral part of many industrial processes. Water entrained in oil and other hydrocarbon products can impede quality specifications. Entrained oil in process water streams puts additional demands on effluent treatment systems. Under the present economic environment, processing production demands push plants and existing equipment beyond the original de...

We define and study a new notion of “robust simulations” between complexity classes which is intermediate between the traditional notions of infinitely-often and almost-everywhere, as well as a corresponding notion of “significant separations”. A language L has a robust simulation in a complexity class C if there is a language in C which agrees with L on arbitrarily large polynomial stretches o...

Properties of Boolean functions on the hypercube that are invariant with respect to linear transformations of the domain are among some of the most well-studied properties in the context of property testing. In this paper, we study the fundamental class of linear-invariant properties called matroid freeness properties. These properties have been conjectured to essentially coincide with all test...

Capillary electrophoresis (CE) has become a powerful tool for enantiomer separations during the last decade. Since 1993, the author has investigated enantiomer separations by affinity capillary electrophoresis (affinity CE) with some proteins and by cyclodextrin electrokinetic chromatography (CDEKC) with some charged cyclodextrins (CDs). Many successful enantiomer separations are demonstrated f...
