    Chaos and 3-cycle: Tales from UGA Physics

    Chaos and 3-cycle: Tales from UGA Physics

    Guest: Prof. M. Howard Lee , UIGA Department of Physics
    Thursday, January 12, 2012 4:00 pm - 5:00 pm
    Location: Physics 202

    The progress on chaos made at UGA was not by design, but by some happenstance in circumstances, tales of which will be woven into this talk. The technical details are as follows:

    The clearest definition of chaos is given by Sharkovskii's theorem, which says that the existence of a 3-cycle in a chaotic map implies chaos. Thus showing a 3-cycle exists is of deepest interest. For the logistic map I have solved the 3-cycle problem[1,2].  At the fully developed chaos I have also proved that the trajectories are ergodic as well by a concept from measure theory.  The same conclusion is reached by my ergometric theory[3].

  • Departmental Colloquium Jan 19, 2012

    The Interaction of the Solar (and Stellar) Winds with the Interstellar Medium

    The Interaction of the Solar (and Stellar) Winds with the Interstellar Medium

    Guest: Prof. Gary Zank , Center for Space Plasma and Aeronomic Research, and Department of Physics, University of Alabama in Huntsville
    Thursday, January 19, 2012 4:00 pm - 5:00 pm
    Location: Physics 202

    The interaction of the solar wind with the interstellar medium is complicated by the presence of a substantial neutral component, interstellar hydrogen. The self-consistent inclusion of neutral hydrogen (and other heavier atoms) requires that models include the effects of charge exchange and scattering properly. With the crossing of the heliospheric termination shock by the Voyager 1 and 2 spacecraft, understanding the outer heliosphere and the heliospheric boundaries has become a topic of great interest. IBEX is now returning observations of Energetic Neutral Atoms (ENAs) created in the solar wind – interstellar medium boundary regions, and these are providing both new insights and new challenges to our understanding of the physics in this complex region. We will describe the status of modeling the solar wind-local interstellar medium interaction, its relationship to Voyager 1 and 2 and IBEX and other remote observations, and the implications for the interaction of stellar winds with their local interstellar environments. The discovery of the hydrogen wall around our heliosphere and other “astrospheres” will be discussed.

  • NanoSEC Seminar Jan 20, 2012

    Imaging and mapping brain architectures

    Imaging and mapping brain architectures

    Guest: Professor Tianming Liu, Department of Computer Science, UGA
    Friday, January 20, 2012 4:00 pm - 5:00 pm
    Location: Riverbend Research South Laboratory Auditorium

    Understanding and mapping the organizational architecture of the brain has been of keen interest for centuries. With the advancements of modern imaging techniques, the pace of scientific discoveries of principles underlying the evolution, development, and organization of brain architectures has been accelerated. This talk will present our recent efforts in discovering general principles of structural, connectional and functional brain architectures by applying macro-scale neuroimaging and micro-scale bioimaging techniques and computational methods. The applications of these discovered principles in neuroscience, medicine and computer science will also be showcased and discussed.
