Caenorhabditis elegans exhibits spontaneous motility in isotropic environments, characterized by periods of forward movements punctuated at random by turning movements. Here, we study the statistics of turning movements-deep Omega-shaped bends-exhibited by swimming worms. We show that the durations of intervals between successive Omega-turns are uncorrelated with one another and are effectively...

One of the most challenging problems in econometrics is the prediction of turning points in financial time series. We compare ARMAand Vector-Autoregressive (VAR-) models by examining their abilities to predict turning points in monthly time series. An approach proposed by Wecker[1] and enhanced by Kling[2] forms the basis to explicitly incorporate uncertainty in the forecasts by producing proba...

The dynamics of one dimensional iterative maps in the regime of fully developed chaos is studied in detail. Motivated by the observation of dynamical structures around the unstable fixed point we introduce the geometrical concept of a turning point which represents a local minimum or maximum of the trajectory. Following we investigate the highly organized and structured distribution of turning ...

Turning points in commodity returns are important for decisions of policy makers, commodity producers and consumers reliant on medium term outcomes. However, forecasting of turning points has been a neglected feature of forecasting, especially in commodity markets. I forecast turning points in metals price returns using Bayesian Decision Theory. The method produces a probabilistic statement abo...

We investigate the motion of a test particle in a d-dimensional, spherically symmetric and static space-time supported by a mass M plus a Λ-term. The motion is strongly dependent on the sign of Λ. In Schwarzschild-de Sitter (SdS) space-time (Λ > 0), besides the physical singularity at r = 0 there are cases with two horizons and two turning points, one horizon and one turning point and the compl...

Resettling into a new country may pose many challenges for unaccompanied refugee minors (URMs). In this study we seek to get better understanding of these through analysing interviews with 48 URMs five years after their arrival in Norway, using the concept turning points as an analytic frame. Gaining sense security, feeling affiliated, being loved and cared for, becoming independent were identi...
