Several authors, e. g. Vermeer et al. [1996], have recently recognized that wavelets may not be the best fit for seismic data since they present large-scale oscillations. They have therefore investigated for instance wavelet packets, local cosine or Gabor transforms. We focus here on filter banks (FB), which can be regarded as a multichannel generalization of wavelets [Duval and Røsten, 2000]. ...

Given a graph G = (V, E), we define the transpose degree sequence d T j to be equal to the number of vertices of degree at least j. We define L G , the graph Laplacian, to be the matrix, whose rows and columns are indexed by the vertex set V , whose diagonal entry at v is the degree of v and whose value at a pair (v, w) is −1 if (v, w) ∈ E and 0 otherwise. Grone and Merris conjectured [GM] Conj...

Introduction: Magnetic data gathered by the Galileo spacecraft [1] as well as images of the tectonically active surface [2,3] provide circumstantial evidence that a soft, probably liquid, layer may exist few kilometers to few tens beneath the cold icy surface of Europa. However, the thickness and the thermal state of the icy crust still remain poorly constrained. Uncertainties mainly results fr...

The antimalarial activity of 22 xanthones against chloroquino-resistant strains of Plasmodium falciparum was evaluated. Natural caloxanthone C (1), demethylcalabaxanthone (2), calothwaitesixanthone (3), calozeyloxanthone (4), dombakinaxanthone (5), macluraxanthone (6), and 6-deoxy-gamma-mangostin (7) were isolated from Calophyllum caledonicum. 1,6-dihydroxyxanthone (8), pancixanthone A (9), iso...
