Deducing self-interaction in eye movement data using sequential spatial point processes
2016
Eye movement data are outputs of an analyser tracking the gaze when a person is inspecting a scene. These kind of data are of increasing importance in scientific research as well as in applications, e.g. in marketing and man-machine interface planning. Thus the new areas of application call for advanced analysis tools. Our research objective is to suggest statistical modelling of eye movement sequences using sequential spatial point processes, which decomposes the variation in data into structural components having interpretation. We consider three elements of an eye movement sequence: heterogeneity of the target space, contextuality between subsequent movements, and time-dependent behaviou…
Existence, uniqueness and Malliavin differentiability of Lévy-driven BSDEs with locally Lipschitz driver
2019
We investigate conditions for solvability and Malliavin differentiability of backward stochastic differential equations driven by a L\'evy process. In particular, we are interested in generators which satisfy a locally Lipschitz condition in the $Z$ and $U$ variable. This includes settings of linear, quadratic and exponential growths in those variables. Extending an idea of Cheridito and Nam to the jump setting and applying comparison theorems for L\'evy-driven BSDEs, we show existence, uniqueness, boundedness and Malliavin differentiability of a solution. The pivotal assumption to obtain these results is a boundedness condition on the terminal value $\xi$ and its Malliavin derivative $D\xi…
Random walk approximation of BSDEs with H{\"o}lder continuous terminal condition
2018
In this paper, we consider the random walk approximation of the solution of a Markovian BSDE whose terminal condition is a locally Hölder continuous function of the Brownian motion. We state the rate of the L2-convergence of the approximated solution to the true one. The proof relies in part on growth and smoothness properties of the solution u of the associated PDE. Here we improve existing results by showing some properties of the second derivative of u in space. peerReviewed

Liiketoimintaprosessien analysointi : avainsuorituskykyindikaattorit analytiikan tukena
2015
Nykypäivän kiihtyvässä globalisaatiossa yritykset ja organisaatiot muokkaavat toimintojaan prosessiorientoituneeksi. Tämä organisaatiorakenteen muutos eroaa huomattavasti perinteisestä organisaatiomallista. Prosessiorientoituneen organisaation ytimenä toimivat liiketoimintaprosessit, jotka tuottavat yrityksen liiketoiminnan tuotteita ja palveluja. Tästä syystä liiketoimintaprosessit ovat nykyisten organisaatioiden keskeisimpiä toimintoja, joita tulee tarkkailla ja analysoida. Analysoinnin avulla pyritään ennustamaan ja tehostamaan liiketoimintaprosesseja erilaisin metodein. Analysoinnissa on tärkeää kiinnittää huomiota liiketoimintaprosessien suorituskykyyn. Suorituskykyä voidaan mitata eri…
CB(1) signaling in forebrain and sympathetic neurons is a key determinant of endocannabinoid actions on energy balance
2010
The endocannabinoid system (ECS) plays a critical role in obesity development. The pharmacological blockade of cannabinoid receptor type 1 (CB(1)) has been shown to reduce body weight and to alleviate obesity-related metabolic disorders. An unsolved question is at which anatomical level CB(1) modulates energy balance and the mechanisms involved in its action. Here, we demonstrate that CB(1) receptors expressed in forebrain and sympathetic neurons play a key role in the pathophysiological development of diet-induced obesity. Conditional mutant mice lacking CB(1) expression in neurons known to control energy balance, but not in nonneuronal peripheral organs, displayed a lean phenotype and res…
