SUMMARY:Colloquium: Dr. Carlos Castro
DESCRIPTION:The Physics department colloquia\, when scheduled\, begin at 3:30 PM on Friday afternoons\, in Lapham Hall\, Room 160 (in the Biology Bldg.). Coffee and cookies are available prior to the talks.  The public is welcome to join. \nThe title of our talk on 11 November 2016 is: “Self-assembly of DNA Nanomechanical Devices”.\nDr. Carlos Castro Assistant Professor\, Mechanical & Aerospace Engineering\, Ohio State University \nStructural DNA nanotechnology is a rapidly emerging field with exciting potential for applications such as single molecule sensing\, drug delivery\, and manipulating molecular components.  However\, the functional scope of DNA nanotechnology is limited by an inability to design dynamic mechanical behavior such as complex motion\, conformational dynamics\, or force generation.  A major focus of our lab is to develop nanomechanical devices by adapting methods used in macroscopic machine design and assembly.  I will discuss our development DNA nanostructures with programmable 1D\, 2D\, and 3D motion as well as dynamic nanostructures with controlled conformational dynamics. We aim to develop devices where nanoscale dynamic behavior (i.e. motion\, conformational distributions\, and kinetics) can be exploited to probe physical properties or manipulate nanoscale components or molecular interactions in real time.  \n   I will present our recent work on implementing a DNA nanocalipers to study the structure and structural dynamics of nucleosomes\, the fundamental packaging unit for genomic DNA in cell nuclei\, which consist of DNA wrapped around a protein core.

SUMMARY:CGCA Seminar: Dr. Christine Lynch
DESCRIPTION:The Leonard E Parker Center for Gravitation\, Cosmology and Astrophysics holds frequent seminars on a broad range of ongoing cosmology and gravitation research topics. Unless otherwise noted\, seminars are on Friday afternoons at 1:00 PM in KIRC 2175; there is a gathering for a brown bag lunch at 12:30. \nChasing Low Frequency Radio Bursts from Magnetically Active Stars \nDr. Christine Lynch\,  University of Sydney \nFlaring activity is a common characteristic of magnetically active stellar systems. These events produce emission throughout the electromagnetic spectrum\, implying a range of physical processes. A growing number of objects are observed to exhibit short-duration\, narrow band\, and highly circularly polarised (reaching 100%) radio bursts. The observed polarisation and frequency-time structure of these bursts points to a coherent emission mechanism such as the electron cyclotron maser. Due to the stochastic nature of these bursts and the sensitivity of current instruments\, the number of stars where coherent emission has been detected is few\, with numbers limited to a few tens of objects. Observations of a wider sample of active stellar systems are necessary in order to establish the percentage that exhibit coherent radio bursts and to relate occurrence of these bursts to basic physical parameters of these stellar objects. New wide-field\, low frequency radio telescopes will probe a frequency regime that is mostly unexplored for many magnetically active star systems and where coherent radio emissions are expected to be more numerous. We are currently carrying out a targeted survey of M dwarf stars with known bright radio flares using the Murchison Widefield Array. The goal of this project is to confirm the flare detections made with single dish telescopes in the 1970s and to better constrain stellar flare rates at 154 MHz. In this talk I will present a recent detection of  four coherent flares from the nearby M dwarf star UV Ceti and disscuss future prospects of detecting a larger sample of M dwarfs using what we know about our UV Ceti observation.
