We prove that the local intersection cohomology of nilpotent orbit closures of cyclic quivers is trivial when the two orbits
involved correspond to partitions with at most two rows. This gives a geometric proof of a result of Graham and Lehrer, which
states that standard modules of the affine Hecke algebra of GLd corresponding to nilpotents with at most two Jordan blocks are multiplicity-free.

Summary The binding and activation of dihydrogen by simple transition metal complexes is of fundamental importance in processes as diverse as the homogeneous or heterogeneous hydrogenation of unsaturated organic molecules(1) and understanding how metalloenzymes such as nitrogenase(2) and the hydrogenases(3) work at the atomic level.Simple consideration of the oxidative-addition of dihydrogen to a coordinatively-unsaturated complex {or its reverse (reductive-elimination)} reveals that the reactions are compelled to proceed via a dihydrogen complex as shown in Equation (1).
However until recently it was considered that the dihydrogen complex had only a fleeting existence. Although there had been some reports in the literature such as that by Ashworth and Singleton(4) that the formally RuIV trihydride, [RuH3(PMe2Ph2]+ was better formulated as the Ru11 species [RuH(H2)(PMe2Ph)2]+, these could not be substantiated. In 1984, though, Kubas showed that the apparently innocuous complex [WH2(CO)3(PPr

)2] contained the side-on bonded dihydrogen molecule, established unambiguously by x-ray, and neutron crystallography and spectroscopy(5). In this highlight the current status of dihydrogen complexes, their structure, identification and in particular their reactivity will be discussed. 相似文献

Abstract— Biophysical and photobiological properties of a group of bacteriochlorins were compared with efficacy of these products for photodynamic therapy of murine tumors. Predictive factors for selective photosensitization in vivo include affinity binding to lipoproteins greater than albumin, extinction coefficient at the wavelength of irradiation and tumor/skin distribution. Efficacy was correlated with circulating plasma levels of the different sensitizers but not with the photodynamic therapy response in cell culture. 相似文献
