Long-range correlations in rectal temperature fluctuations of healthy infants during maturation. [PDF]
PLoS ONE, 2009 BACKGROUND:Control of breathing, heart rate, and body temperature are interdependent in infants, where instabilities in thermoregulation can contribute to apneas or even life-threatening events.

Statistical properties of detrended fluctuation analysis
Journal of Statistical Computation and Simulation, 2010 The main goal of this work is to consider the detrended fluctuation analysis (DFA), proposed by Peng et al. [Mosaic organization of DNA nucleotides, Phys. Rev. E. 49(5) (1994), 1685–1689]. This is a well-known method for analysing the long-range dependence in non-stationary time series.

Movement Disorders, EarlyView.Abstract Background Deep brain stimulation (DBS) targeted to the globus pallidus (GP) can effectively alleviate dystonia symptoms. However, identifying optimal therapeutic stimulation parameters is challenging due to the manual programming process and the paucity of acute effects of DBS on dystonia symptoms.

Oikos, EarlyView.Animal breeding phenology in temperate and high latitude regions is often predicted by weather variables, such as temperature. Much work on this topic has focused on taxonomic groups that employ adaptive plastic responses to annual variation in an environmental cue, with analytical approaches developed to determine when weather has an effect and the ...

Mathematics, 2020 Financial and geophysical data, like many other low and high frequency time series, are known to exhibit some memory effects. These memory effects may be long or short, permanent or temporal depending on the event that is being modeled.

Complexity signatures in the geomagnetic H component recorded by the Tromsø magnetometer (70° N, 19° E) over the last quarter of a century [PDF]
Nonlinear Processes in Geophysics, 2014 Solar disturbances, depending on the orientation of the interplanetary magnetic field, typically result in perturbations of the geomagnetic field as observed by magnetometers on the ground.

Critical Transitions In a Model of a Genetic Regulatory System
, 2014 We consider a model for substrate-depletion oscillations in genetic systems, based on a stochastic differential equation with a slowly evolving external signal. We show the existence of critical transitions in the system.
