    Chlamydomonas swims with two "gears" in a eukaryotic version of run-and-tumble locomotion (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-07-25
    Description: The coordination of eukaryotic flagella is essential for many of the most basic processes of life (motility, sensing, and development), yet its emergence and regulation and its connection to locomotion are poorly understood. Previous studies show that the unicellular alga Chlamydomonas, widely regarded as an ideal system in which to study flagellar biology, swims forward by the synchronous action of its two flagella. Using high-speed imaging over long intervals, we found a richer behavior: A cell swimming in the dark stochastically switches between synchronous and asynchronous flagellar beating. Three-dimensional tracking shows that these regimes lead, respectively, to nearly straight swimming and to abrupt large reorientations, which yield a eukaryotic version of the "run-and-tumble" motion of peritrichously flagellated bacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Polin, Marco -- Tuval, Idan -- Drescher, Knut -- Gollub, J P -- Goldstein, Raymond E -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):487-90. doi: 10.1126/science.1172667.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Wilberforce Road, Cambridge CB3 0WA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19628868" target="_blank"〉PubMed〈/a〉

    Periodicity and chaos in coupled nonlinear oscillators (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-04-07
    Description: A system of coupled tunnel diode relaxation oscillators shows a variety of complex periodic states as the external voltage is varied. The existence of chaotic or nonperiodic states is more dependent on the nature of the coupling than on the number of degrees of freedom. A simple but accurate numerical model shows many of the phenomena observed experimentally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gollub, J P -- Brunner, T O -- Danly, B G -- New York, N.Y. -- Science. 1978 Apr 7;200(4337):48-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17847328" target="_blank"〉PubMed〈/a〉

    Flagellar Kinematics and Swimming of Algal Cells in Viscoelastic Fluids (2015)
    Springer Nature
    Details
    Publication Date: 2015-03-18
    Description: The motility of microorganisms is influenced greatly by their hydrodynamic interactions with the fluidic environment they inhabit. We show by direct experimental observation of the bi-flagellated alga Chlamydomonas reinhardtii that fluid elasticity and viscosity strongly influence the beating pattern - the gait - and thereby control the propulsion speed. The beating frequency and the wave speed characterizing the cyclical bending are both enhanced by fluid elasticity. Despite these enhancements, the net swimming speed of the alga is hindered for fluids that are sufficiently elastic. The origin of this complex response lies in the interplay between the elasticity-induced changes in the spatial and temporal aspects of the flagellar cycle and the buildup and subsequent relaxation of elastic stresses during the power and recovery strokes.

    Three-dimensional instabilities of film flows (1995)

    Notes: Two-dimensional (2-D) interfacial waves on flowing films are unstable with respect to both two- and three-dimensional instabilities. In this paper, several distinct three-dimensional instabilities that occur in different regions of the parameter space defined by the Reynolds number R and the frequency f of forced two-dimensional waves are discussed in detail. (a) A synchronous 3-D instability, in which spanwise deformations of adjacent wave fronts have the same transverse phase, appears over a wide range of frequency. These transverse modulations occur mainly along the troughs of the primary waves and eventually develop into sharp and nearly isolated depressions. The instability involves many higher harmonics of the fundamental 2-D waves. (b) A 3-D surbharmonic instability occurs for frequencies close to the neutral curve fc(R). In this case, the transverse modulations are out of phase for successive wave fronts, and herringbone patterns result. It is shown that this weakly nonlinear instability is due to the resonant excitation of a triad of waves consisting of the fundamental two-dimensional wave and two oblique waves. The evolution of wavy films after the onset of either of these 3-D instabilities is complex. However, sufficiently far downstream, large-amplitude solitary waves absorb the smaller waves and become dominant. © 1995 American Institute of Physics.

    Inverting chaos: Extracting system parameters from experimental data (1996)

    Notes: Given a set of experimental or numerical chaotic data and a set of model differential equations with several parameters, is it possible to determine the numerical values for these parameters using a least-squares approach, and thereby to test the model against the data? We explore this question (a) with simulated data from model equations for the Rossler, Lorenz, and pendulum attractors, and (b) with experimental data produced by a physical chaotic pendulum. For the systems considered in this paper, the least-squares approach provides values of model parameters that agree well with values obtained in other ways, even in the presence of modest amounts of added noise. For experimental data, the "fitted'' and experimental attractors are found to have the same correlation dimension and the same positive Lyapunov exponent. © 1996 American Institute of Physics.

    Solitary wave dynamics of film flows (1994)

    Notes: The development and interaction of solitary wave pulses is critical to understanding wavy film flows on an inclined (or vertical) surface. Sufficiently far downstream, the wave structure consists of a generally irregular sequence of solitary waves independent of the conditions at the inlet. The velocity of periodic solitary waves is found to depend on their frequency and amplitude. Larger pulses travel faster; this property, plus a strong inelasticity, causes larger pulses to absorb others during interactions, leaving a nearly flat interface behind. These wave interactions lead to the production of solitary wave trains from periodic small amplitude waves. The spacings between solitary waves can be irregular for several different reasons, including the amplification of ambient noise, and the interaction process itself. On the other hand, this irregularity is suppressed by the addition of periodic forcing.
