Weyl group multiple Dirichlet series were associated with a root system Φ and a number field F containing the n-th roots of unity by Brubaker, Bump, Chinta, Friedberg and Hoffstein [3] and Brubaker, Bump and Friedberg [4] provided n is sufficiently large; their coefficients involve n-th order Gauss sums and reflect the combinatorics of the root system. Conjecturally, these functions coincide wi...

Marie-Anne Félix is a Research Director at the CNRS (Centre National de la Recherche Scientifique, France) and a Principal Investigator at the Institut Jacques Monod in Paris. She started her scientific career in cell biology, and later turned to development and evolution. In the last years, her laboratory focused on evolution of vulva development in the nematode Caenorhabditis elegans and othe...

This had been a celebratory year for Anne McLaren. In April, her 80th birthday was marked in Cambridge, UK by a special symposium in her honor on germ cells and stem cells, two subjects very close to her heart and the main themes of her research endeavors throughout her career. Many of her colleagues and friends from all over the world gathered to participate in lively scientific sessions, grea...

S UBACUTE bacterial endocarditis involves the left side of the heart in nearly all cases. The complete descriptions of the disease by Libman and Friedberg,’ Blumer,2 and Middleton and Burke3 refer chiefly to this common type. The vegetations are confined to the right side of the heart in less than 4 per cent of the cases.4*6 In patent ductus arteriosus complicated by subacute bacterial endarter...

Assume V ̸= L. Then L is not E-Recursively Enumerable in any member of L via a forcing argument inspired by Friedberg [1]. This approach leads to an extension of Levy-Shoenfield absoluteness. §
