Lagrangian study of surface transport in the Kuroshio Extension area based on simulation of propagation of Fukushima-derived radionuclides [PDF]
Lagrangian approach is applied to study near-surface large-scale transport in the Kuroshio Extension area using a simulation with synthetic particles advected by AVISO altimetric velocity field.

Ascertaining when a basin is Wada: the merging method
Trying to imagine three regions separated by a unique boundary seems a difficult task. However, this is exactly what happens in many dynamical systems showing Wada basins.

Statistical analysis of Lagrangian transport of subtropical waters in the Japan Sea based on AVISO altimetry data [PDF]
Northward near-surface Lagrangian transport of subtropical waters in the Japan Sea frontal zone is simulated and analysed based on altimeter data for the period from 2 January 1993 to 15 June 2015.

Realization of multivariable nonlinear systems via the approaches of differential forms and differential algebra [PDF]
summary:In this paper differential forms and differential algebra are applied to give a new definition of realization for multivariable nonlinear systems consistent with the linear realization theory.

Jamming by compressing a system of granular crosses
A disordered stress-free granular packing can be jammed, transformed into a mechanically rigid structure, by increasing the density of particles or by applying shear deformation.

Complexity of cortical wave patterns of the wake mouse cortex
The cerebral cortex has ongoing electrical activities with rich and complex patterns in space and time. Here, the authors use optical voltage imaging in mice and computational methods, relating these complexities to different levels of wakefulness.

Observability of nonlinear systems [PDF]
Summary: Observability of a general nonlinear system -- given in terms of an ODE \(\dot {x}=f(x)\) and an output map \(y=c(x)\) -- is defined as in linear system theory (i.e.\,if \(f(x)=Ax\) and \(c(x)=Cx\)). In contrast to standard treatment of the subject we present a criterion for observability which is not a generalization of a known linear test ...

Perturbation solutions of fifth order oscillatory nonlinear systems [PDF]
Oscillatory systems play an important role in the nature. Many engineering problems and physical systems of fifth degrees of freedom are oscillatory and their governing equations are fifth order nonlinear differential equations.
