Threshold-activated transport stabilizes chaotic populations to steady states
We explore Random Scale-Free networks of populations, modelled by chaotic Ricker maps, connected by transport that is triggered when population density in a patch is in excess of a critical threshold level. Our central result is that threshold-activated dispersal leads to stable fixed populations, for a wide range of threshold levels. Further, suppression of chaos is facilitated when the thresh...
متن کاملLattice Approach to Threshold States
I review lattice QCD results relevant to the recently discovered hadrons: X(3782), Y (4260), and Ds(2317), because these seem, to me at least, to be the most interesting states from the perspective of solving and understanding QCD . The physical picture behind lattice QCD calculations is that an interpolating operator creates a hadron in the QCD vacuum. and after a specific time interval the ha...
متن کاملSteady States in Hierarchical Structured Populations with Distributed States at Birth
We investigate steady states of a quasilinear first order hyperbolic partial integro-differential equation. The model describes the evolution of a hierarchical structured population with distributed states at birth. Hierarchical size-structured models describe the dynamics of populations when individuals experience size-specific environment. This is the case for example in a population where in...
متن کاملApplication of a steady states transport model to condensation of water droplets on a substrate
The employed transport model consists of a periodic lattice and a gas of indistinguishable particles, so that each site i is occupied by zero or mi particles. At every time step a random site i is chosen and a particle may leave to an adjacent site with probability proportional to a hopping rate u(mi|mi−1,mi+1). The hopping rate is chosen so that particles tend to condensate by incorporating a ...
متن کاملLocalization of Chaotic Resonance States due to a Partial Transport Barrier.
Chaotic eigenstates of quantum systems are known to localize on either side of a classical partial transport barrier if the flux connecting the two sides is quantum mechanically not resolved due to Heisenberg's uncertainty. Surprisingly, in open systems with escape chaotic resonance states can localize even if the flux is quantum mechanically resolved. We explain this using the concept of condi...
