A large class of evolving nonequilibrium systems, known collectively as cellular structures,
are composed of nearly-uniform domains of polygonal-like or polyhedral-like shape (in two-or …

We study an experimental orbit on a two-torus with a golden-mean winding number obtained
from a forced Rayleigh-Bénard system at the onset of chaos. This experimental orbit is …

We have studied segregation in binary mixtures of different granular media subjected to
rotation in horizontal tubes. Mixtures separate into bands of different relative concentrations …

We have studied the pearling instability induced on hollow tubular lipid vesicles by hydrophilic
polymers with hydrophobic side groups along the backbone. The results show that the …

In this Letter we study the evolution of a two-dimensional soap froth. We present experimental
evidence for the existence of a limiting scale-invariant distribution of the number of sides in …

The SOS genetic network is responsible for the repair/bypass of DNA damage in bacterial
cells. While the initial stages of the response have been well characterized, less is known …

We report results from an experimental study of coarsening in thin layers of succinonitrile in
the presence of impurities. We quench the latter from the liquid phase to different …

The lysis-lysogeny decision of bacteriophage lambda (λ) is a paradigm for developmental
genetic networks. There are three key features, which characterize the network. First, after …

We have studied experimentally the dynamics of soap froths in two dimensions. We observe
two temporal regimes: a transient in which the average bubble area increases in time faster …

Cyanobacteria carry out oxygenic photosynthesis, play a key role in the cycling of carbon
and nitrogen in the biosphere, and have had a large impact on the evolution of life and the …
