A tipping point for tipping points
Oikos, EarlyView.Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Empirical assessment of bifurcation regions within new Keynesian models [PDF]
As is well known in systems theory, the parameter space of most dynamic models is stratified into subsets, each of which supports a different kind of dynamic solution.

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

On homoclinic chaos and a control chaos strategy applied to a free-joint nonholonomic manipulator
, 2015 In this work, the occurrence of chaos (homoclinic scene) is verified in a robotic system with two degrees of freedom by using Poincare-Mel'nikov method.

Stability calculations for piecewise-smooth delay equations [PDF]
, 2008 This paper describes a new method for computing the stability of nonsmooth periodic orbits of piecewise-smooth dynamical systems with delay. Stability computations for piecewise-smooth dynamical systems without delay have previously been performed using ...

Stratospheric influence on tropical cyclone evolution
Quarterly Journal of the Royal Meteorological Society, EarlyView.We developed a metric based on moist static energy to detect and quantify the intrusion of stratospheric air into the inner core of tropical cyclones. High‐resolution numerical simulations show that this stratospheric interaction forms warm anomalies (high‐level warm cores) in the upper troposphere.

Existence of Bifurcation in Macroeconomic Dynamics: Grandmont was Right [PDF]
Grandmont (1985) found that the parameter space of the most classical dynamic general-equilibrium macroeconomic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic ...

Control-based continuation for investigating nonlinear experiments [PDF]
, 2010 This paper presents a systematic experimental study of two one-degree-of-freedom nonlinear devices using the newly introduced control-based continuation method by Sieber and Krauskopf [Nonlinear Dynamics 2008].
