On the parameterization of all admissible pairs in a class of CCF-ILC algorithms

This paper extends some recent results on the parameterization of all admissible pairs in a class of 2-parameter current-cycle-feedback ILC algorithms. In addition, a necessary and sufficient condition is given under which the associated set of equivalent controllers coincides with the set of all stabilizing controller

Rate and Mechanism of the Oxidative Addition of Benzoic Anhydride to Palladium(0) Complexes in DMF

The rate constant of the oxidative addition of the benzoic anhydride (PhCO)2O to [Pd0(PPh3)4] has been determined in DMF and compared to that of phenyl halides and phenyl triflate. The following reactivity order has been established: PhI >> (PhCO)2O > PhOTf > PhBr. The oxidative addition of (PhCO)2O proceeds by activation of one C−O bond. Two acyl-PdII complexes are formed: a neutral complex trans-[(PhCO)Pd(OCOPh)(PPh3)2] and a cationic complex trans-[(PhCO)PdS(PPh3)2]+ (S = DMF) showing that the decarbonylation process is highly endergonic. The exchange of PPh3 by the bidentate ligand dppp does not favor the decarbonylation process.

Massive galaxies with very young AGN

Gigahertz Peaked Spectrum (GPS) radio galaxies are generally thought to be the young counterparts of classical extended radio sources and live in massive ellipticals. GPS sources are vital for studying the early evolution of radio-loud AGN, the trigger of their nuclear activity, and the importance of feedback in galaxy evolution. We study the Parkes half-Jansky sample of GPS radio galaxies of which now all host galaxies have been identified and 80% has their redshifts determined (0.122 < z < 1.539). Analysis of the absolute magnitudes of the GPS host galaxies show that at z > 1 they are on average a magnitude fainter than classical 3C radio galaxies. This suggests that the AGN in young radio galaxies have not yet much influenced the overall properties of the host galaxy. However their restframe UV luminosities indicate that there is a low level of excess as compared to passive evolution models.Comment: To appear in the proceedings of "Formation and Evolution of Galaxy Bulges", IAUS 245; M.

Influence of Phosphoramidites in Copper-Catalyzed Conjugate Borylation Reaction

Copper(I) has become the preferred metal to catalyze the β-boration of α,β-unsaturated carbonyl compounds, and now we demonstrate that easily accessible monodentate chiral ligands, such as phosphoramidites and phosphites, can be convenient alternative ligands to induce asymmetry in the enantioselective version of this reaction, particularly in the β-boration of α,β-unsaturated imines.

Veranderingsprocessen in ziekenhuizen : de contouren van een antwoord op een complexe problematiek

In de twee voorgaande boeken van dezelfde redactie, die als ondertitel hadden ‘bedrijfskundig instrumentarium voor de ziekenhuismanager’, worden zowel de bedrijfskundige instrumenten als de (feitelijke en mogelijke) toepassingen daar van beschreven, toegespitst op instellingen voor gezondheidszorg c.q. ziekenhui zen. Het gaat om instrumenten, gericht op de sturing van (zorg)processen en structurering van de (zorg)organisatie. Kenmerkende thema’s zijn onder andere (opname- en operatie)planning, werklastmeting, procesbeheersing, rooster afstemming, coördinatie, kwaliteit, informatievoorziening, prestatiesturing, unitmanagement en divisiestructuren. Het bedrijfskundig instrumentarium en de genoemde thema’s zijn in ziekenhuizen niet aan de orde als doel op zich. De verwachting is dat er hoe dan ook een bij drage wordt geleverd aan een beter functionerende organisatie. ‘Beter functione ren’ is op zichzelf een loze kreet; bet gaat om doelstellingen en de mate waarin doelstellingen worden gerealiseerd. Dit hoofdstuk gaat expliciet in op de samen hang tussen bedrijfskundig instrumentarium en organisaties in verandering. Daar naast wordt getracht een kader te geven voor de veranderkundige elementen uit de overige bijdragen in dit boek

Modeling and prediction of surgical procedure times

Accurate prediction of medical operation times is of crucial importance for cost efficient operation room planning in hospitals. This paper investigates the possible dependence of procedure times on surgeon factors like age, experience, gender, and team composition. The effect of these factors is estimated for over 30 different types of medical operations in two hospitals, by means of ANOVA models for logarithmic case durations. The estimation data set contains about 30,000 observations from 2005 till 2008. The relevance of surgeon factors depends on the type of operation. The factors found most often to be significant are team composition, experience, and daytime. Contrary to widespread opinions among surgeons, gender has nearly never a significant effect. By incorporating surgeon factors, the accuracy of out-of-sample prediction of case durations of about 1,250 surgical operations in 2009 is improved by up to more than 15 percent as compared to current planning procedures.planning;ANOVA model;European hospital;current procedure terminology (CPT);health care management;lognormal distribution;operation room;surgeon factors
