This paper is devoted to the study of a certain class of principal bundles on del Pezzo surfaces, which were introduced and studied by Friedman and Morgan in [10]: The two authors showed that there exists a unique principal bundle (up to isomorphism) on a given (Gorenstein) del Pezzo surface satisfying certain properties. We call these bundles almost(More)
The allergic mediator release inhibitor CI-949 [5-methoxy-3-(1-methylethoxy)-1-phenyl-N-1H-tetrazol-5-yl-1H-indole-2-carboxamide,l-arginine salt] was evaluated for its effect on the activation of human eosinophils, macrophages, and neutrophils by the phagocytic stimulus serum-opsonized zymosan (SOZ). CI-949 inhibited the SOZ-stimulated respiratory burst of(More)
From an embedded resolution we obtain for the local smooth fiber of a complex hypersurface singularity a decomposition in compact disjoint sets. The decomposition is invariant by the geometric monodromy. The action of the monodromy on a subset is a cyclic permutation or a cyclic root of a translation on a torus. From this decomposition one can compute(More)
The cell activation inhibitor CI-959 (5-methoxy-3-(1-methyl-ethoxy)-N-1H-tetrazol-5-ylbenzo[b]thiophene-2-carboxamide, monosodium salt) was evaluated for its effect on the activation of human eosinophils, macrophages, and neutrophils by the phagocytic stimulus serum-opsonized zymosan (SOZ). CI-959 inhibited the respiratory burst of eosinophils and(More)
We formulate the Nahm transform in the context of parabolic Higgs bundles on P 1 and extend its scope in completely algebraic terms. This transform requires parabolic Higgs bundles to satisfy an admissibility condition and allows Higgs fields to have poles of arbitrary order and arbitrary behavior. Our methods are constructive in nature and examples are(More)
0.1. Notations and Conventions. During this note, we will fix a base field k (e.g. the complex numbers C). The multiplicative group of the field k will be denoted by Gm. All the vector spaces considered will be finite dimensional vector spaces over the field k. For a given vector space V of dimension≥ 1, we will denote the dual vector space, the projective(More)
