| 10:00 - 11:00 Computational Soft- and Bio-materials group biweekly journal club Flory theory of randomly branched polymers School NANO SCIENCES Flory theory of randomly branched polymers Randomly branched polymer chains (or trees) are a classical subject of polymer physics with connections to the theory of magnetic systems, percolation and critical phenomena. More recently, the model has been reconsidered for RNA, supercoiled DNA and the crumpling of topologically-constrained polymers. While solvable in the ideal case, little is known exactly about randomly branched polymers with volume interactions. Flory theory provides a simple, unifying description for a wide range of branched systems, including isolated trees in good and teta-solvent, and tree melts. In particu ... 10:00 - 17:00 International Conference on p-adic Aspects of Automorphic Forms School MATHEMATICS International Conference on p-adic Aspects of Automorphic Forms ... 13:30 - 15:00 Weekly Seminar Integral Field Unit in Astronomy School ASTRONOMY Integral field Unit (IFU) is an optical instrument enabling us to obtain a 3D view of the galaxy in one shot. The IFU data contain both spectrographic and imaging information of every single pixel of the field. Astronomers use IFU information to measure the motion of gasses ripped out of galaxies, the distance of the galaxies and etc. In this talk, the IFU instrument and its different configurations are introduced. I further demonstrate experimental results derived from existing IFUs data. Finally, our progress in Technology Development Division toward fabricating an IFU for INO340 telescope is reported. ... 14:00 - 15:00 Weekly Seminar Combinatorics and Computing School MATHEMATICS Hypergraph extensions of the Erd?s-Gallai theorem ... 14:00 - 17:00 Weekly Seminar Operator Algebra and its Applications School MATHEMATICS Rokhlin dimension for compact group actions. ... 14:00 - 15:00 Weekly Seminar Plasmonic (Linear/Nonlinear)- Biomedical Applications School NANO SCIENCES Plasmonic (Linear/Nonlinear)- Biomedical Applications Localized Surface Plasmon Resonance (LSPR) in metallic nanostructures has found lots of different applications over the last decade; integrated optic, energy, material characterization, imaging and medicine. The sensitivity of the SPR to the localized and dynamic characteristics of surrounding makes them a bright candidate as a sensing element for label free characterizations in single molecule level. The resulted enhancement of electric field in SPR can be exploited not only in linear applications, but in nonlinear techniques as well; nonlinear plasmonic . In this ... 15:00 - 16:00 Weekly Seminar Plasma-Based High-Gradient Accelerator School PARTICLES AND ACCELERATORS The highest conventional electron energy accelerator, Stanford Linear Accelerator (SLAC), has got an accelerating gradient of 0.001 keV/?m. CERN prepares to test revolutionary plasma based mini-accelerator, promising to shrink costs and size of particle accelerators for science, medical applications and industry significantly. Laser-driven plasma accelerator at Lawrence Berkeley National Lab achieved the acceleration gradient of 10 keV/?m. Magnetic coaxial plasma accelerator, MCPA, provides the highest gradient of 100 keV/?m. IAEA has recognized this device as a first test bench for testing of plasma facing materials, diagnostic development a ... |
