How to compute suitable vicinity parameter and sampling time of recurrence analysis
We show how the maximum of recurrence-microstates entropy configures a new way to properly compute appropriate recurrence vicinity parameter and time sampling to perform recurrence analysis of continuous data....

Puzzle in inverse problems: Tsallis noise and Tsallis norm
Inverse problems are challenging in several ways, and we cite the non-linearity and the presence of non-Gaussian noise. Least squared is the standard method to construct a equivalent functional for optimizatio...

Effect of Chemical and Visual Cues in the Maze Performance of the Ant Dinoponera quadriceps
Ants use chemical, visual, magnetic and/or solar cues during foraging activity. Orientation is important, since foragers need to return to the nest. In this study, we analyze the maze performance of the Dinoponer...

Open AccessEphaptic entrainment in hybrid neuronal model
In recent decades, there has been a growing interest in the impact of electric fields generated in the brain. Transmembrane ionic currents originate electric fields in the extracellular space and are capable o...

Using data from nesting beach monitoring and satellite telemetry to improve estimates of marine turtle clutch frequency and population abundance
Population abundance data are often used to define species’ conservation status. Abundance of marine turtles is typically estimated using nesting beach monitoring data such as nest counts and clutch frequency ...

Full-waveform Inversion Based on q-Laplace Distribution
Full-waveform inversion (FWI) is a powerful methodology employed in estimating subsurface physical parameters. FWI is classically formulated as a data-fitting problem based on minimizing the squared ...

Nonextensive statistical mechanics for robust physical parameter estimation: the role of entropic index
The problem of inferencing parameters of complex systems from measured data has been extensively studied based on the inverse problem theory. Classically, an inverse problem is formulated as an optimisation ta...

Open AccessWaiting-time statistics in magnetic systems
Many complex systems, from earthquakes and financial markets to Barkhausen effect in ferromagnetic materials, respond with a noise consisting of discrete avalanche-like events with broad range of sizes and dur...

Lunar phases and hawksbill sea turtle nesting
The behavior of sea turtle species can be influenced by the lunar cycle, possibly due to moonlight variability. We analyzed the relationship between nesting behavior and moon phase using nesting hawksbill turt...

Topologic distance in the Lucena network
The Lucena network (LN) is the dual of a multifractal partition of the square. We analyze the relation between the typical topologic distance l and the number of vertices N of the LN. The multifractal partition ...

Open AccessOmnivory by Planktivores Stabilizes Plankton Dynamics, but May Either Promote or Reduce Algal Biomass
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by...
