Sci Total Environ. 1991 Jan 01;101(1):101-9. doi: 10.1016/0048-9697(91)90108-q.

This paper describes the use of an interactive simulation system (SONCHES) as a model and databank system. The basic model is a physiologically based toxicokinetic model (partition coefficient concept). This model takes circulation times into consideration and includes a...

Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional imaging. It is particularly advantageous for applications where conventional microscopy is not able to image deeper layers of samples in a reasonable time, e.g. in fast moving, deeper lying...

Two delay-coupled semiconductor lasers are studied in the regime where the coupling delay is comparable to the time scales of the internal laser oscillations. Detuning the optical frequency between the two lasers, novel delay-induced scenarios leading from optical frequency...

Tristability of a semiconductor laser due to time-delayed optical feedback.

Physical review. E, Statistical, nonlinear, and soft matter physics

Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Mar;79(3):036211. doi: 10.1103/PhysRevE.79.036211. Epub 2009 Mar 30.

We present an experimental and theoretical study of multistability of a single-mode laser subject to feedback through phase tuning and amplifier sections integrated on the same chip. Closely above threshold, a regime of tristability of continuous-wave (CW) states is...

Measurements of ionic structure in shock compressed lithium hydride from ultrafast x-ray Thomson scattering.

We present the first ultrafast temporally, spectrally, and angularly resolved x-ray scattering measurements from shock-compressed matter. The experimental spectra yield the absolute elastic and inelastic scattering intensities from the measured density of free electrons. Laser-compressed lithium-hydride samples are well...

Odd-number theorem: optical feedback control at a subcritical Hopf bifurcation in a semiconductor laser.

Physical review. E, Statistical, nonlinear, and soft matter physics

A subcritical Hopf bifurcation is prepared in a multisection semiconductor laser. In the free-running state, hysteresis is absent due to noise-induced escape processes. The missing branches are recovered by stabilizing them against noise through application of phase-sensitive noninvasive delayed...

The classical oceanographic problem of deducing the unknown constant in the dynamic method-the problem of the "level of no motion"-may be treated as a geophysical inverse problem. The unknown "barotropic" velocity may be chosen to satisfy an arbitrary number...
