Several years ago we noted that narrow graphene ribbons exhibited resistances that are always close to 26 k Ohms, which corresponds to the resistance quantum h\/e2 where h is Planck\u2019s constant an e is the charge of the electron, that turned out to be caused by a unique state at the edge of the ribbon.

Moreover, several of its properties resemble those of a Majorana fermion which was predicted in 1937. Very recently we have also discovered that the first graphene layer to grow on the silicon terminated silicon carbide crystal face, which has long been considered to an insulator, is in fact an excellent semiconductor when it is properly annealed. It is found to have a band gap of 0.6 eV and a room temperature mobility that exceeds 5000 cm2\/Vs, which is greater than that of silicon and exceeds all other 2D semiconductors by a factor of 20 or more (Nature, in press).

For over two decades, intracellular actin filaments have been thought to elongate at their barbed ends and depolymerize from pointed ends. This process, referred to as \u201ctreadmilling\u201d has formed the central bedrock of our understanding of actin dynamics. Recent results from our lab however suggest that the treadmilling dogma might not always hold true. Using a combination of \u003Cem\u003Ein vitro\u003C\/em\u003E multicolor single molecule and single filament reconstitution experiments, we have discovered two new activities that call for reevaluation of the treadmilling dogma. First, we discovered the first-ever pointed-end polymerase VopF that processively polymerizes filament pointed ends in cells and from purified proteins. Further, VopF accelerates polymerization in presence of profilin and is a mechanosensitive protein - its rate of polymerization increases under pN-range pulling forces. Second, we have recently discovered that twinfilin, a member of the cofilin family of proteins, induces depolymerization of filament barbed ends. Interestingly we find that the depolymerase twinfilin, polymerase formin and blocker CP form a multicomponent complex at the filament barbed end. Importantly, both of these processes persist in physiological conditions containing high concentrations of profilin-bound monomers \u2013 strongly indicating intracellular implications for these newly discovered activities. Taken together, our findings call for taking a fresh look at actin treadmilling and its implications in cellular actin dynamics.\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003EBiography: \u003C\/span\u003E\u003C\/span\u003E\u003C\/strong\u003E\u003Cbr \/\u003E\r\n\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EDr. Shashank Shekhar is an assistant professor of physics and cell biology at Emory University.

For over two decades, intracellular actin filaments have been thought to elongate at their barbed ends and depolymerize from pointed ends. This process, referred to as \u201ctreadmilling\u201d has formed the central bedrock of our understanding of actin dynamics. Recent results from our lab however suggest that the treadmilling dogma might not always hold true. Using a combination of \u003Cem\u003Ein vitro\u003C\/em\u003E multicolor single molecule and single filament reconstitution experiments, we have discovered two new activities that call for reevaluation of the treadmilling dogma. First, we discovered the first-ever pointed-end polymerase VopF that processively polymerizes filament pointed ends in cells and from purified proteins. Further, VopF accelerates polymerization in presence of profilin and is a mechanosensitive protein - its rate of polymerization increases under pN-range pulling forces. Second, we have recently discovered that twinfilin, a member of the cofilin family of proteins, induces depolymerization of filament barbed ends. Interestingly we find that the depolymerase twinfilin, polymerase formin and blocker CP form a multicomponent complex at the filament barbed end. Importantly, both of these processes persist in physiological conditions containing high concentrations of profilin-bound monomers \u2013 strongly indicating intracellular implications for these newly discovered activities. Taken together, our findings call for taking a fresh look at actin treadmilling and its implications in cellular actin dynamics.\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003EBiography: \u003C\/span\u003E\u003C\/span\u003E\u003C\/strong\u003E\u003Cbr \/\u003E\r\n\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EDr. Shashank Shekhar is an assistant professor of physics and cell biology at Emory University.

While many chaotic systems have known governing equations and are deterministically ``solved,\u0022 we still lack a comprehensive framework for predicting, controlling, and simply making sense of such systems. And while recent advances in technology allow us to explore these systems through direct numerical simulation better than ever before, the need for an insightful theoretical framework is still very much alive.\u0026nbsp;\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nSuch a framework exists in a subset of chaotic systems, known as Axiom A chaotic systems and, as a result, Axiom A systems are understood quite well. However, the requirements for a system to be Axiom A are quite strict, and the overlap between systems that are Axiom A and those that are physically significant is quite small.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nA very important concept in Axiom A systems is the notion of shadowing, which allows the chaotic dynamics to be decomposed piecewise-in-time in terms of much easier to analyze solutions known as periodic orbits.

Particularly, we have observed a high-energy astrophysical diffuse neutrino flux using the IceCube Neutrino Observatory at the South Pole for the past 10 years. However, the specific sources that contribute to this flux are not known. More recently, IceCube reported evidence of neutrino emission from the nearby AGN and Seyfert II galaxy NGC 1068. In this work, I present a new method to ask: Is NGC 1068 a time-variable neutrino source? By applying this method to an identical data sample that was used to report the evidence of emission, I conclude that the neutrino emission from NGC 1068 is consistent with a steady source. This new method can be applied to future candidate point sources observed by IceCube and serves as a source characterization tool. \u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EHawking radiation elegantly unifies quantum field theory, general relativity, and thermodynamics.

The transformation from primordial to heavier elements starts with the first generation of stars, through nuclear fusion in their cores. These first stars, called Population III or Pop III, are the first radiating objects, formed from metal-free gas clouds in the very early universe. The supernova deaths of these stars leads to the enrichment of their local environments with new metals, and can leave behind neutron stars as remnants. These compact objects can end up in binary systems with other neutron stars, and eventually merge, which allows for the rapid neutron capture (r-process) to take place.

The transformation from primordial to heavier elements starts with the first generation of stars, through nuclear fusion in their cores.

The supernova deaths of these stars leads to the enrichment of their local environments with new metals, and can leave behind neutron stars as remnants.

Liquid crystal (LC), one of the textbook soft matter, is the core material of our Digital Age which still amazes us with new findings and applications. In this talk, I will introduce a series of LC-based systems under microscopy to see how the partial order of LCs gives rise to novel phenomena in a wide range of materials problems. First, I will show the confined LCs having unique elastic properties manifest unexplored topological aspects of chiral materials. In the second part, pulsating bubbles dispersed in LC reveal a critical role of spatiotemporal symmetry breaking of the anisotropic medium in the bubbles\u0026#39; propulsion. Extending this problem, we adopt motile bacteria in LC to study how bacteria interact with liquid-liquid interfaces. Lastly, unveiling skin formation in drying deposits of aqueous LCs and solutions, I will share my vision for future soft matter research utilizing X-ray\/neutron radiography.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBio: \u003C\/strong\u003EJoonwoo Jeong is currently an associate professor in the Department of Physics at UNIST (Ulsan National Institute of Science and Technology), Korea.

I will discuss my recent works on spin liquids in two types of such manageable systems: moire heterostructures in van der Waals materials where many tuning knobs are available; and monitored quantum circuits where designer gates and measurements are exploited as new sources of frustrations.\u003C\/em\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Constructive approaches to frustrated magnetism: Moir\u00e9 and Measurements"}],"uid":"35687","created_gmt":"2023-01-09 23:52:22","changed_gmt":"2023-01-09 23:54:46","author":"kcolebrooke3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-01-12T11:00:00-05:00","event_time_end":"2023-01-12T12:00:00-05:00","event_time_end_last":"2023-01-12T12:00:00-05:00","gmt_time_start":"2023-01-12 16:00:00","gmt_time_end":"2023-01-12 17:00:00","gmt_time_end_last":"2023-01-12 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"166937","name":"School of Physics"},{"id":"4215","name":"colloquium"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"662941":{"#nid":"662941","#data":{"type":"event","title":"Georgia Tech Observatory: Lunar Eclipse","body":[{"value":"\u003Cp\u003EOn Tuesday, the Georgia Tech Observatory will be open from 4 a.m. EST until sunrise, and will stream the partial and total lunar eclipse\u0026nbsp;on YouTube via our Aloha Telescope program.\u003C\/p\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003E\u003Cstrong\u003ELivestream:\u003C\/strong\u003E \u003Ca href=\u0022http:\/\/youtube.com\/c\/thegeorgiatechobservatory\u0022\u003Eyoutube.com\/c\/thegeorgiatechobservatory\u003C\/a\u003E\u003C\/li\u003E\r\n\t\u003Cli\u003E\u003Cstrong\u003EIn Person:\u003C\/strong\u003E \u003Ca href=\u0022https:\/\/astronomy.gatech.edu\/\u0022\u003EGeorgia Tech Observatory at Howey Physics Building\u003C\/a\u003E\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ELunar Eclipse Timeline for Atlanta:\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003E4:09 am Tue, Nov 8\u0026nbsp;\u0026nbsp;\u0026nbsp;

It was Finkelstein\u0026rsquo;s extension of the Schwarzschild metric which provided Penrose with an opening into general relativity and set him on the path to his 1965 discovery celebrated by this year\u0026rsquo;s prize.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe other half of the 2020 Nobel Prize in Physics was awarded jointly to Reinhard Genzel and Andrea Ghez for the discovery of \u0026mdash; in Ghez\u0026rsquo;s words \u0026mdash; \u0026quot;The Monster at the heart of the Milky Way,\u0026quot; a black hole whose existence had been hypothesized since the early 1970s.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn order to visually observe an object that famously does not emit any light, precise measurements of stars moving in the black hole\u0026rsquo;s gravitational field had to be carried out. The independent work of Genzel and Ghez mapping the positions of these stars over many years has led to the clearest evidence yet that the center of our Milky Way galaxy contains \u0026ldquo;The Monster\u0026rdquo;, that possibly every galaxy contains a black hole, and that the environment near it looks nothing like what was expected.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003ELearn more: \u003Ca href=\u0022https:\/\/cos.gatech.edu\/news\/2020-nobel-prizes-chemistry-and-physics-explained-genetic-scissors-black-holes-and-milky-ways\u0022\u003E2020 Nobel Prizes in Chemistry and Physics, Explained\u003C\/a\u003E\u003C\/em\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Ca href=\u0022https:\/\/primetime.bluejeans.com\/a2m\/live-event\/bpahkcyb\u0022\u003EJoin us on BlueJeans\u003C\/a\u003E as local experts from Georgia Tech and Emory University help explain the 2020 Nobel Prize in Physics \u0026mdash; from the pioneering theoretical work on black holes, to observing the galactic center of our Milky Way.

In this talk, we will present growth and structure data as well as ARPES measurements showing the new semiconducting graphene bands. \u0026nbsp;I will show what growth conditions lead to these new semiconducting bands.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Discovery of New Form of Semiconducting Graphene"}],"uid":"27664","created_gmt":"2016-02-23 10:16:54","changed_gmt":"2017-04-13 21:16:31","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-03-01T10:00:00-05:00","event_time_end":"2016-03-01T11:00:00-05:00","event_time_end_last":"2016-03-01T11:00:00-05:00","gmt_time_start":"2016-03-01 15:00:00","gmt_time_end":"2016-03-01 16:00:00","gmt_time_end_last":"2016-03-01 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"166937","name":"School of Physics"},{"id":"166896","name":"seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:amorain@gatech.edu\u0022\u003Eamorain@gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"505041":{"#nid":"505041","#data":{"type":"event","title":"The packing of hard particles: From granular media, to metallic glasses, to protein cores.","body":[{"value":"\u003Cp\u003EThe packing of hard particles has fascinated scientists for centuries: from Kepler\u0027s conjecture about dense sphere packings, to Hales\u0027 experiments on the respiration ability of peas, to Bernal\u0027s studies of ball bearings that describe liquid structure.\u0026nbsp; In this talk, I will describe theoretical and computational studies that employ hard-particle models (with purely repulsive contact interactions) to describe: 1) the variation of the number of interparticle contacts in packings of frictional spheres, 2) the glass-forming ability of bulk metallic glasses (BMGs), and 3) the side chain conformations of hydrophobic residues in protein cores.

In OPNMR, one uses optical pumping with circularly polarized light to create spin-polarized electrons in a semiconductor. The electron spin can be transferred to the nuclear spin bath through the Fermi contact hyperfine interaction which can then be detected by conventional NMR. The resulting NMR signal can be enhanced four to five orders of magnitude or more over the thermal equilibrium signal. We report on our OPNMR and magneto-optical studies in semiconductor nanostructures such as GaAs and InMnSb quantum wells. We focus on the theoretical calculations for the average electron spin polarization at different photon energies for different values of external magnetic field in both unstrained and strained quantum wells. The calculations are based on the 8- band Pidgeon-Brown model generalized to include the effects of the quantum confinement potential as well as pseudomorphic strain at the interfaces.

In this seminar, I will initially describe multidimensional coherent spectroscopy measurements of polariton correlations in GaAs quantum-well Fabry-Perot microcavities at 4K in order to discuss the dynamics of polariton condensate formation. These experiments measure polariton-polariton spectral correlations that produce the condensate, and their evolution on ultrafast timescales.

I show how this superexponential scaling of the turbulent lifetime in pipe flow is related to extreme value statistics, which I show is a manifestation of a mapping between transitional turbulence and the statistical mechanics model of directed percolation.\u0026nbsp; This mapping itself arises from a further surprising and remarkable connection: laminar and turbulent regions in a fluid behave as a predator-prey ecosystem. Such ecosystems are governed by individual fluctuations in the population and being naturally quantized, are solvable by path integral techniques from field theory.

In areas where wildlife experiences unrestricted movement through previously affected zones, residual, unexploded landmines present a significant and potentially lethal problem. Anecdotal reports of African elephants (Loxodonta africana), in a once war-torn Angola, avoiding mine-fields together with telemetry data suggest that the species may be able to detect concealed landmines using olfaction. Before any in-field experiments can be conducted, an elephant\u2019s olfactory capacity for the detection of the most commonly used component in landmines, trinitrotoluene (TNT), needed to be established. Using three African elephants under controlled conditions, we used operant conditioning to test whether elephants are able to detect and reliably indicate the presence of TNT using olfaction. Elephants detected and indicated TNT using olfaction at levels greater than chance, with high sensitivity and selectivity, even when in the presence of highly volatile distractor odors.

Little is known about how gut microbial communities vary in space and time: how they grow, fluctuate, and respond to various perturbations. To address this and investigate microbial colonization of the vertebrate gut, my lab applies light sheet fluorescence microscopy to a model system that combines a realistic in vivo environment with a high degree of experimental control: larval zebrafish with defined subsets of commensal bacterial species. Light sheet microscopy enables three-dimensional imaging with high resolution over the entire intestine, providing visualizations that would be difficult or impossible to achieve with other techniques. Quantitative analysis of large image datasets enables measurement of bacterial abundances and distributions. I will describe this approach and focus especially on experiments in which a colonizing bacterial species is challenged by the invasion of a second species, which leads to the decline of the first group. In one two-member system, imaging reveals dramatic population collapses that differentially affect the two species due to their different biogeographies and morphologies. The collapses are driven by the peristaltic motion of the zebrafish intestine, indicating that the physical activity of the host environment can play a major role in mediating inter-species competition. In a second two-member system, control of inter-bacterial killing allows control of succession dynamics, highlighting the role of specific biophysical machineries in shaping inter-species interactions.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"School of Physics Colloquium"}],"uid":"28004","created_gmt":"2016-08-04 15:40:38","changed_gmt":"2017-04-13 21:15:13","author":"Dione Morton","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-09-19T16:00:00-04:00","event_time_end":"2016-09-19T16:00:00-04:00","event_time_end_last":"2016-09-19T16:00:00-04:00","gmt_time_start":"2016-09-19 20:00:00","gmt_time_end":"2016-09-19 20:00:00","gmt_time_end_last":"2016-09-19 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"559511":{"id":"559511","type":"image","title":"Prof. Raghuveer Parthasarathy","body":null,"created":"1470339866","gmt_created":"2016-08-04 19:44:26","changed":"1475895364","gmt_changed":"2016-10-08 02:56:04","alt":"Prof. Raghuveer Parthasarathy","file":{"fid":"218267","name":"raghu_parasarathy_photo.png","image_path":"\/sites\/default\/files\/images\/raghu_parasarathy_photo.png","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/raghu_parasarathy_photo.png","mime":"image\/png","size":95965,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/raghu_parasarathy_photo.png?itok=Naii9d2V"}}},"media_ids":["559511"],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"166937","name":"School of Physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EDione Morton\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:dione.morton@physics.gatech.edu\u0022\u003Edione.morton@physics.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"562941":{"#nid":"562941","#data":{"type":"event","title":"Soft-matter mechanics in the initiation and robustness of bacterial biofilms","body":[{"value":"\u003Cp\u003EBiofilms are communities of microbes that are embedded in a self-produced matrix of polymer and proteins.\u0026nbsp; Biofilms cause chronic, recalcitrant infections - even bacteria that are easily cleared by antibiotics and\/or the immune system when they are in a free-swimming, so-called \u0022planktonic\u0022 state become highly resistant to both antibiotics and the immune system when they are in a biofilm.

We perform adaptive mesh simulations using Enzo including both momentum-driven AGN feedback and star formation to study the interplay between ICM cooling, AGN heating and star formation over 6.5 Gyr in an isolated cool-core cluster. We find that AGN jets globally heat up the ICM via weak shock waves and turbulence. Locally, cold clumps can cool out of the ICM due to the non-linear perturbation driven by the AGN jets. These cold clumps feed both star formation and the supermassive black hole (SMBH), triggering an AGN outburst which increases the entropy of the ICM and reduces its cooling rate. When star formation completely consumes the cold gas, leading to a brief shutoff of the AGN, the ICM quickly cools and develops multiphase gas again, followed by another cycle of star formation\/AGN outburst.

As a result, we find that \u003Cem\u003EQ\u003C\/em\u003E is mainly determined by stochastic frequency broadening rather than frictional damping, in analogy to nuclear magnetic resonance. In addition, recently several research groups have demonstrated placing graphene on hexagonal BN (hBN) with crystallographic alignment. This not only creates a protected environment yielding high-mobility devices, but also due to the resulting superlattice formed in these heterostructures, an energy gap, secondary Dirac Points, and Hofstadter quantization in a magnetic field have been observed.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn these systems, we observe a p Berry\u0026rsquo;s phase shift in the magneto-oscillations when tuning the Fermi level past the secondary Dirac points, originating from a change in topological pseudospin winding number from odd to even when the Fermi-surface electron orbit begins to enclose the secondary Dirac points. We also observe a distinct hexagonal pattern in the longitudinal resistivity versus magnetic field and charge density, resulting from a systematic pattern of replica Dirac points and gaps, reflecting the fractal spectrum of the Hofstadter butterfly.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFinally, we study the properties of additional graphene\/hBN layer electrostatically gated structures such as twisted trilayers that are comprised of AB-stacked bilayer graphene contacting a graphene monolayer through a twist angle, and hBN-encapsulated graphene bilayers with large applied perpendicular electric field. In the twisted trilayers, which couple the massive bilayer spectrum to that of the massless monolayer spectrum, the interlayer interactions and screening produce a nonlinear monolayer graphene gate capacitance and renormalize the bilayer band structure. In the encapsulated bilayers, we perform Landau level spectroscopy, measure the layer polarizability of the electrons, and observe easy-axis quantum Hall ferromagnetism.

We will present and discuss a puzzling example of viral adaptive strategy: viruses with multipartite genomes. Multipartite viruses possess fragmented genomes with fragments encapsidated in independent viral particles. This demands co-infection of cells to complete the viral cycle, a condition that poses severe restrictions on the number of viral particles infecting single cells. This kind of viruses infects mostly plants and represents about 16% of all viral species described.

This organization is driven by the forces exerted by atoms and molecules on one another. At high temperatures, the organization consists only of local conspiracies that continually form and decay but are too small to have much impact. At low temperatures, however, the conspiracies spread to become global revolutions, which bring new phases of matter that exhibit new properties reflecting the new organization. Rigidity, magnetism, liquid crystallinity, and superconductivity are just a handful of examples of such properties, which we call emergent collective properties.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EUntil recently, organization meant geometry: Picture the tidy lattice of ions in a crystal of table salt.

Then, I will discuss a therapeutic strategy to exploit the fluctuations to facilitate treatment success.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Stochastic nature of bacterial eradication using antibiotics"}],"uid":"27664","created_gmt":"2016-11-11 18:00:20","changed_gmt":"2017-04-13 21:13:59","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-11-15T15:00:00-05:00","event_time_end":"2016-11-15T16:00:00-05:00","event_time_end_last":"2016-11-15T16:00:00-05:00","gmt_time_start":"2016-11-15 20:00:00","gmt_time_end":"2016-11-15 21:00:00","gmt_time_end_last":"2016-11-15 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"166937","name":"School of Physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003Eshaun.ashley@physics.gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"583816":{"#nid":"583816","#data":{"type":"event","title":"The Physics of Genes and the Promise of Personalized Medicine","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ESchool of Physics Inquiring Minds Public Lecture: Prof. Alek Aksimentiev, University of Illinois at Urbana-Champaign \u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe\u0026nbsp;twenty-first century is poised to see dramatic advances in medicine. The rapid\u0026nbsp;progress in understanding the molecular causes of disease and the emergence of new\u0026nbsp;treatment strategies are fueled by the development of physical instruments that can characterize biological\u0026nbsp;processes at extreme resolution and provide the means to harness biological systems\u0026nbsp;for technological uses.\u0026nbsp;One common target of such investigations is DNA, which,\u0026nbsp;after water and oxygen, is the most famous\u0026nbsp;molecule of life known. This is not surprising, as the eye-catching double\u0026nbsp;helix of\u0026nbsp;DNA carries instructions to manufacture and assemble all the\u0026nbsp;components of a living organism. The wealth of information encoded in DNA often\u0026nbsp;overshadows its unusual\u0026nbsp;physical properties, for example, the possibility of an\u0026nbsp;effective attraction between same-charge DNA molecules regulated by their\u0026nbsp;nucleotide sequence. Furthermore, the\u0026nbsp;methods used to determine the\u0026nbsp;informational content of DNA\u0026mdash;its nucleotide sequence\u0026mdash;until now relied on\u0026nbsp;biological processes. In this lecture, I will describe our recent efforts\u0026nbsp;to\u0026nbsp;characterize the physical properties of DNA and determine their role in\u0026nbsp;orchestrating the function of a biological cell. I will demonstrate how the\u0026nbsp;physical properties of DNA\u0026nbsp;can be used to build a physics-based reader of the\u0026nbsp;DNA sequence.

Substrate- and product-bound structures of BcsA provide the basis for substrate recognition and demonstrate the stepwise elongation of cellulose. Our structural snapshots reveal that BcsA translocates cellulose via a ratcheting mechanism involving a \u0026lsquo;finger helix\u0026rsquo; that contacts the polymer\u0026rsquo;s terminal glucose.

The power generated by a wind turbine fluctuates due to the variable wind speed that blows past the turbine. Indeed, the spectrum of wind power fluctuations is widely believed to reflect the Kolmogorov spectrum of atmospheric turbulence; both vary with frequency $f$ as $f^{-5\/3}$. This variability decreases when aggregate power fluctuations from geographically distributed wind plants are averaged at the grid {\\it via} a mechanism known as {\\it geographic smoothing}. Neither the $f^{-5\/3}$ wind power fluctuation spectrum nor the mechanism of geographic smoothing are understood.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this talk, I will chart out the non-equilibrium character of wind power fluctuations, and explain the wind power fluctuation spectrum from the turbine through the grid scales. The $f^{-5\/3}$ wind power fluctuation spectrum results from the largest length scales of atmospheric turbulence of order 200 km influencing the small scales where individual turbines operate. This long-range influence correlates outputs from geographically distributed wind plants over a range of frequencies that decreases with increasing inter-farm distance. Consequently, aggregate grid-scale power fluctuations remain correlated, and are smoothed until they reach a limiting $f^{-7\/3}$ spectrum, which is confirmed with field data.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe Spectrum of Wind Power Fluctuations\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"The Spectrum of Wind Power Fluctuations "}],"uid":"27664","created_gmt":"2016-12-07 15:56:09","changed_gmt":"2017-04-13 21:13:42","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-01-20T11:00:00-05:00","event_time_end":"2017-01-20T12:00:00-05:00","event_time_end_last":"2017-01-20T12:00:00-05:00","gmt_time_start":"2017-01-20 16:00:00","gmt_time_end":"2017-01-20 17:00:00","gmt_time_end_last":"2017-01-20 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"},{"id":"1316","name":"Green Buzz"}],"categories":[],"keywords":[{"id":"166937","name":"School of Physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003Eamorain@gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"584928":{"#nid":"584928","#data":{"type":"event","title":"Semi-Classics for Spin Chains","body":[{"value":"\u003Ch3\u003E\u003Cstrong\u003ESchool of Physics Nonlinear Physics Seminar: Maram Akila, Willkommen an der Universit\u0026auml;t Duisburg-Essen\u003C\/strong\u003E\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EIn the limit of small\u0026nbsp; h-bar, e.g. short wavelengths, the Gutzwiller trace formula relates the quantum mechanical spectrum and the periodic orbits of the classical system (and vice versa).
