Spherical splines are used to define approximate solutions to strongly elliptic pseudodifferential equations on the unit sphere. These equations arise from geodesy. The approximate solutions are found by using Galerkin method. We prove optimal convergence (in Sobolev norms) of the approximate solution by spherical splines to the exact solution. Our numerical results underlie the theoretical res...

In recent decades, decomposition techniques have enabled increasingly more applications for dimension reduction, as well as extraction of additional information from geophysical time series. Traditionally, the principal component analysis (PCA)/empirical orthogonal function (EOF) method and more recently the independent component analysis (ICA) have been applied to extract, statistical orthogon...

Some recent results are reported from the ARGUS experiment, operated at the e+estorage ring DORIS Il at DESY. In an updated analysis of semileptonic b u decays direct evidence for such transitions was obtained through reconstruction of a complete event. A study of the lepton energy spectra in +-+ E-UP and z+ P-I+ decays yielded a value for the Michel parameter which is in good agreement with a ...

Insurance markets are characterized by profound market imperfections. Insurance intermediaries reduce transaction costs and information asymmetries. From transaction cost economics, agency theory, and law and economics literature the hypothesis is derived that insurance brokers may provide more high-quality information and advisory services which are better suited for the needs of the consumers...

The observation of the T meson [1,2] as a narrow resonance in e l ec t ron-pos i t ron annihilations in the DORIS storage ring indicates that the T is a bound jPC = 1 state of a new quark and its antiquark. If this interpretat ion is correct, there should be narrow excited states of the T, in analogy with the J / ¢ family. The FNAL experiment [3], which originally discovered the q" in p ro ton-...

The wiggler beamline BW6 at DORIS is dedicated to protein crystallography. The facility is financed by the Max-Planck Society (MPG). It may be used also by other academic or industrial groups on the basis of research proposals or for proprietary research. The webpage www.mpasmb-hamburg.mpg.de/bw6/ provides further information on the access to the beamline. For academic usage, an interactive onl...
