This study considers the multivariate segmentation procedure under the assumption of the multivariate Gaussian mixture. Jensen-Shannon divergence between two multivariate Gaussian distributions is employed as a discriminator and a recursive segmentation procedure is proposed. The daily log-return time series for 30 currency pairs consisting of 12 currencies for the last decade (January 3, 2001 ...

Abstract Quantum walks are powerful tools for building quantum search algorithms. However, these success probabilities far below 1. Amplitude amplification is usually used to amplify probability, but the souffl'e problem follows. Only stop at right step can we achieve a maximum probability. Otherwise, as number of steps increases, probability may decrease, which will cause troubles in practical...

short timeframe, and rapid approaches are needed to assess log Pow values of these compounds (2,4,7). Several separation-based approaches for indirectly determining log Pow values in a rapid fashion have been reported, including reversed-phase high performance liquid chromatography (HPLC) (2,3,8–11), thin-layer chromatography (12,13), micellar electrokinetic chromatography (MEKC) (7,14–16), and...

The transmembrane anion transport activity of a series of synthetic molecules inspired by the structure of tambjamine alkaloids can be tuned by varying the lipophilicity of the receptor, with carriers within a certain log P range performing best.

Finding audiovisual material for reuse in new programs is an important activity for news producers, documentary makers, and other media professionals. Such professionals are typically served by an audiovisual broadcast archive. We report on a study of the transaction logs of one such archive. The analysis includes an investigation of commercial orders made by the media professionals and a chara...

Die asymptotische Entwicklung der Funktion Z(t) = eζ(1/2 + it) für reelle t → +∞ (dabei ist θ(t) = = log Γ(1/4 + it/2)− (t log π)/2 und ζ(1/2 + it) die Riemannsche Zetafunktion auf der kritischen Geraden <(s) = 1/2) – heute allgemein als Riemann-SiegelFormel bezeichnet – wird auf neue Weise mit Hilfe der Sattelpunktmethode aus der sogenannten Riemann-Siegel-Integralformel hergeleitet. Die Forme...
