The ocean returns: Mapping a mercurial Anthropocean [PDF]
Social Science Information, 2018 Humans have dumped ‘stuff’ in oceans in a particularly concentrated way since the Industrial Revolution, the effects of which we now note as evidence of the Anthropocene – or the Anthropocean. In this article, I consider what the oceans now return to us in the form of pollution.

Return-map for semiconductor lasers with optical feedback [PDF]
1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003 It is well known that a semiconductor laser exposed to moderate optical feedback and biased near threshold exhibits the phenomenon of low-frequency intensity fluctuations (LFF). While this behavior can be numerically simulated using the so-called Lang-Kobayshi model, the interpretation of the phenomenon has remained a controversy.

Contracting return maps for monotone delayed feedback
Discrete and Continuous Dynamical Systems, 2001 The existence and stability of slowly oscillating periodic solutions to the delay differential equation \[ \dot x(t)=-\mu x(t)+f(x(t-1)) \] is derived for nonlinearities \(f\) which satisfy the standard negative feedback condition, \(xf(x)0\), \(f(x)=\text{sign\,} (x)=+1\) for ...

A robust return‐map algorithm for general multisurface plasticity
International Journal for Numerical Methods in Engineering, 2016 SummaryThree new contributions to the field of multisurface plasticity are presented for general situations with an arbitrary number of nonlinear yield surfaces with hardening or softening. A method for handling linearly dependent flow directions is described. A residual that can be used in a line search is defined.
