We analyse phase and frequency synchronization in the human cardio-respiratory system. The method for analysis of noisy nonstationary bivariate data is applied to simultaneously measured cardiac and respiratory activity. Short epochs of phase and/or frequency locking between respiratory and...

Signals derived from the human cardiovascular system are well known to exhibit highly complex, nearly periodic, oscillatory behaviour whose nature is something of an enigma. It has, for example, been variously described as chaotic, fractal, stochastic, and subject to 1/f fluctuations—and its...

Electric circuits, which produce oscillations at widely separated time scales, cause a huge computational effort in a numerical simulation of the mathematical model based on differential-algebraic equations (DAEs). Alternatively, a multidimensional signal model yields a description via multirate...

The functional integral formalism is used to provide a unified treatment of the effect of squeezing of the bath and frequency modulation of the system–bath coupling on the decoherence and dissipation properties of an open quantum system. The system chosen is a standard one consisting of a...

This study aims at evaluating the accuracy of mitosis detection on multispectral histopathological images by developing a solution specifically designed to take advantage of multi-spectral information. The proposed framework includes a selection of spectral bands and focal plane, detection of...

Fraud und Wirtschaftskriminalität ist unverändert ein Thema für Unternehmen und deren Stakeholder. Berücksichtigt man die mediale Aufmerksamkeit, die in den vorangegangenen Monaten Wirtschafts- und Bilanzskandalen gewidmet wurde, kann man sogar sagen, Fraud und Wirtschaftskriminalität sind...

Informationsüberflutung bei Konsumenten, Mitarbeitern und Führungskräften führt – nacheiner Reihe von Studien – zu erheblichen wirtschaftlichen Verlusten und sozialen Problemen.Ein fruchtbares Forschungsthema mit Differenzierungspotenzial ist demnach die Situierungund Individualisierung....

Das Gesundheitswesen in Deutschland steht vor großen Herausforderungen. Diedemographische Entwicklung führt zu einer wachsenden Anzahl älterer undsomit oft auch hilfebedürftiger Menschen (vgl. [Bund01], S. 69.). Gleichzeitigsinkt aber der Anteil der erwerbstätigen Bevölkerung und somit die...

The aim of the research was to determine the impact of selected corporate governance mechanisms on the scope of disclosures related to control system over financial reporting in Poland and Germany. The research group comprised of companies from the Warsaw WIG 30 index and the German DAX index in...

This study empirically investigates the relationships of control levers (belief and boundary systems, Simons 1995) and control context (social and performance management context, Gibson and Birkinshaw 2004) with contextual ambidexterity and firm performance. Based on cross-sectional survey data...
