Recent experience has shown that interior-point methods using a log barrier approach are far superior to classical simplex methods for computing solutions to large parametric quantile regression problems. In many large empirical applications, the design matrix has a very sparse structure. A typical example is the classical fixed-effect model for panel data where the parametric dimension of the ...

Par un heureux concours de circonstances, ce dossier, elabore a l’occasion du centenaire la fondation l’American Library in Paris (ALP), partage rubrique « Eclairages » numero d’IdeAs, Idees d’Amerique avec celui consacre aux etudes americaines en Europe, sous direction Serge Jaumain et Sonia Lehman-Frisch. De fait, creation mai 1920 d’une bibliotheque langue anglaise dans capitale francaise re...

We study the necessary condition under which a resonantly driven exciton polariton superfluid flowing against an obstacle can generate turbulence. The value of critical velocity is well estimated by transition from elliptic to hyperbolic operator following ideas developed Frisch, Pomeau, Rica for flow around obstacle, though nature equations governing quite different. find analytical estimates ...

We study the complexity of network dynamics in a couple of very different model classes: The traditional random Boolean networks (RBN) and Frisch-Hasslacher-Pomeau lattice gas automata (FHP). For this we formulate the FHP dynamics as a probabilistic Boolean network (PBN). We use the set complexity of successive network states to assess the complexity of the dynamics. We find that the complexity...

In previous studies (Tanrhis and Frisch, 1951a,b) it was found that a human blood medium was satisfactory for determining the susceptibility of Mycobacterium tuberculosis to streptomycin. This investigation was undertaken to determine whether the same medium would be suitable also for performing isoniazid susceptibility tests, and to compare it with the American Trudeau Society (Report of the C...

The variation of the monomeric friction coefficient of styrene butadiene copolymer (SBR) and natural rubber (NR) with various degrees of cure was analyzed. Samples with different levels of cure were prepared. Loss tangent measurements of the samples were performed by means of a damped torsion pendulum between 173 K and 373 K. Data were analyzed in the frame of the Kloczkowsky, Mark and Frisch m...

Successful honey bee foragers communicate where they have found a good resource with the waggle dance, a symbolic language that encodes a distance and direction. Both of these components are repeated several times (1 to > 100) within the same dance. Additionally, both these components vary within a dance. Here we discuss some causes and consequences of intra-dance and inter-dance angular variat...
