Goldman [Gol] and Turaev [Tur] found a Lie bialgebra structure on the vector space generated by non-trivial free homotopy classes of curves on a surface. When the surface has non-empty boundary, this vector space has a basis of cyclic reduced words in the generators of the fundamental group and their inverses. We give a combinatorial algorithm to compute this Lie bialgebra on this vector space ...

These lectures describe Hecke algebra isomorphisms and types for depth-zero principal series blocks, a.k.a. Bernstein components Rs(G) for s = sχ = [T, e χ]G, where χ is a depth-zero character on T (O). (Here T is a split maximal torus in a p-adic group G.) We follow closely the treatment of A. Roche [Ro] with input from D. Goldstein [Gol] and L. Morris [Mor]. We give an elementary proof that (...

Background: In polyarticular juvenile idiopathic arthritis (pJIA) biologic therapies are often combined with methotrexate (MTX). This combination was shown to increase efficacy in adult rheumatoid patients. MTX may also have a protective effect on the formation of anti-drug antibodies and thus prolong drug survival. pJIA, there few sometimes controversial data available. Objectives: To compare ...

The LHCb Outer Tracker is a straw drift detector with a modular design and a total of 53760 readout channels distributed over a sensitive area of 12 double layers of 6x5 m each. The main electronics readout requirement is the precise ( 0.5 ns) drift time measurement at an occupancy of ∼4% and 1 MHz readout. A total of 128 channels are read out by one Front-End box. About half of the FE−Boxes ha...

A comparison of chlorophyll data from SeaWiFS imagery and modeling results from a 3D hydrodynamical model was performed over the northwestern Mediterranean for the entire year of 2001. The study aims at investigating the information content brought by satellite-derived chlorophyll concentration ([Chl]) maps concerning surface dynamics in coastal zone. The study is mainly focused on the Gulf of ...

English. Despite the impressive results achieved by ASR technology in the last few years, state-of-the-art ASR systems can still perform poorly when training and testing conditions are different (e.g., different acoustic environments). This is usually referred to as the mismatch problem. In the ArtiPhon task at Evalita 2016 we wanted to evaluate phone recognition systems in mismatched speaking ...
