Continuum theory of gene expression waves during vertebrate segmentation [PDF]
The segmentation of the vertebrate body plan during embryonic development is a rhythmic and sequential process governed by genetic oscillations. These genetic oscillations give rise to traveling waves of gene expression in the segmenting tissue.

Approach to predictability via anticipated ynchronization [PDF]
8 pages.-- PACS nrs.: 05.45.Xt, 95.10.Fh, 87.18.Sn.Predictability of chaotic systems is limited, besides the precision of the knowledge of the initial conditions, by the error of the models used to extract the nonlinear dynamics from the time series.

Chaos Synchronization and Spontaneous Symmetry Breaking in Symmetrically Delay Coupled Semiconductor Lasers [PDF]
PACS: 05.45.Xt, 42.55.Px, 42.65.SfWe present experimental and numerical investigations of the dynamics of two device-identical, optically coupled semiconductor lasers exhibiting a delay in the coupling.

Coupled phase oscillators model a variety of dynamical phenomena in nature and technological applications. Non-local coupling gives rise to chimera states which are characterized by a distinct part of phase-synchronized oscillators while the remaining ...

Reconstructing effective phase connectivity of oscillator networks from observations
We present a novel approach for recovery of the directional connectivity of a small oscillator network by means of the phase dynamics reconstruction from multivariate time series data. The main idea is to use a triplet analysis instead of the traditional

Large-deviation properties of resilience of power grids
We study the distributions of the resilience of power flow models against transmission line failures via a so-called backup capacity. We consider three ensembles of random networks, and in addition, the topology of the British transmission power grid ...

Basins of attraction for chimera states
Chimera states—curious symmetry-broken states in systems of identical coupled oscillators—typically occur only for certain initial conditions. Here we analyze their basins of attraction in a simple system comprised of two populations.

Curing critical links in oscillator networks as power flow models
Modern societies crucially depend on the robust supply with electric energy so that blackouts of power grids can have far reaching consequences.
