Zinc(II) phthalocyanine (ZnPC) is a new photosensitizer currently undergoing phase I and II clinical trials at Lausanne's CHUV hospital for the photodynamic therapy (PDT) of early cancer in the upper aerodigestive tract. Activated oxygen species other than singlet oxygen produced during the photosensitization of ZnPC in liposomes have been examined by… (More)
Erd˝ os-Ko-Rado sets in finite classical polar spaces are sets of generators that intersect pairwise non-trivially. We improve the known upper bound for Erd˝ os-Ko-Rado sets in H(2d + 1, q 2) for d > 2 and d even from approximately q d 2 +d to q d 2 +1 .
A cross-intersecting Erd˝ os-Ko-Rado set of generators of a finite classical polar space is a pair (Y, Z) of sets of generators such that all y ∈ Y and z ∈ Z intersect in at least a point. We provide upper bounds on |Y | · |Z| and classify the cross-intersecting Erd˝ os-Ko-Rado sets of maximum size with respect to |Y | · |Z| for all polar spaces except some… (More)
