SUMMARY:Colloquium: M. Yusuf Ali
DESCRIPTION:This special Physics department colloquium is scheduled for Monday 5/18/15 at 3:30 pm in Room 135.  Coffee\, tea and cookies are served at 3:15 pm in the same room.  Anyone is welcome. \nMyosin V: A Molecular Motor designed for intracellular cargo transport\nDr. M. Yusuf Ali\, Assistant Professor\, Department of Molecular Physiology and Biophysics\, College of Medicine\, University of Vermont \nIntracellular cargo transport is ciritical for normal cellular function in all living organisms.  Myosin V is a molecular motor responsible for carrying a variety of intracellular cargoes.  It is a tiny\, biological nano-machine that walks along actin filament tracks and powers this movement by hydrolyzing ATP and converting chemical energy into mechanical work.  While carrying cargo\, each molecule can travel long distances (~1µm) at a speed of 400 nm/s\, taking 36nm hand-over-hand steps and generating ~2 piconewton forces.  Although a single myosin V is sufficient to transport cargo in vitro\, a team of motors is required to transport cargo to its destination within cells.  I have initiated a unique set of single-molecule biophysical experiments to understand how multiple myosin V motors communicate\, cooperate\, or even interfere with each other while transporting cargo through the complicated cytoskeletal network of actin tracks.  In addition\, myosin V-based transport may be regulated by adapter proteins\, which are binding partners of myosin V.  However\, the role of these adapter proteins are poorly understood.  Therefore\, my long-term research goals are to understand the molecular basis of intracellular cargo transport by teams of molecular motors.

Anyone is welcome. \nMutant Ribosomes and the Action of Antibiotics\nDr. Hasan Demirci\, Research Associate\, Stanford PULSE Institute; Research Associate\, Stanford Synchrotron Radiation Lighthouse\, SLAC National Accelerator Laboratory\, Menlo Park\, CA \nHigh-resolution ribosome structures determined by X-ray crystallography have provided important insights into the mechanism of translation and antibiotic action.  Such studies thus far have relied on large ribosome crystals kept at cryogenic temperatures to reduce radiation damage.  I will first describe my work on mechanisms of streptomycin action\, streptomycin resistance and streptomycin dependence carried out at synchrotron light sources.  then I will discuss the application of Serial Femtosecond X-ray crystallography (SFX) using an X-ray free-electron laser (XFEL) to obtain diffraction data from ribosome microcrystals in liquid suspension at ambient temperature.  30S ribosomal subunit microcrystals diffracted to beyond 3.5 Å resolution in preliminary experiments\, demonstrating the feasibility of using SFX for structural studies of ribosomes.  The ability to collect diffraction data at near-physiological temperatures promises to provide new fundamental insights into the structural dynamics of ribosome complexes.

Anyone is welcome. \nNew Views of Black Hole Disk Winds\nDr. Jon M. Miller\, Dept. of Astronomy\, University of Michigan  \nHigh-resolution X-ray spectroscopy has been central to revealing the nature of X-ray winds from accreting massive black holes.  These winds may ultimately have important effects on the evolution of host galaxies.  However\, early studies with Chandra may have given a partially skewed view of the radii at which such winds originate\, and the mechanisms by which they are driven. \nWith an eye toward the coming Astro-H era\, I will briefly review past results\, and then highlight some new and emerging views of black hole disk winds.  Where possible\, I will draw analogies between parallel investigations in accreting stellar-mass black holes.  Overall\, new results may suggest that disk winds may originate closer to the black hole\, and carry more mass than previously appreciated.

DESCRIPTION:This special Physics department colloquium is scheduled for Tuesday 5/5/15 at 4:00 pm in Room 135.  Coffee\, tea and cookies are served at 3:45 pm in the same room.  Anyone is welcome. \nBroken Time-Reversal in High-Tc Superconductors\nManoj Kumar Kashyap\, PhD Candidate/UWM Dept. of Physics \nA century after the discovery of superconductivity at the lab of Kamerlingh Onnes in 1911\, it is noticeable that the phenomenon is quite ubiquitous in nature.  In addition to a long list of superconducting alloys and compounds\, almost half the elements in the periodic table superconduct.  By the late seventies\, superconductivity was thought to be well understood.  This turned out to be a myth\, with the discovery of unconventional superconductors that defied Bardeen-Cooper-Schrieffer (BCS) theory.  Cuprates have been the most prominent example since their discovery in 1986 by Bednorz and Müller.  This discovery was followed by yttrium barium copper oxide (YBCO) in 1987\, commencing the era of high temperature superconductivity.  The astonishingly rich phase diagram of cuprates includes the pseugap phase which was earlier thought to be a precursor to superconductivity.  Now signatures of broken symmetries have been seen\, indicating a true phase transition.  Is it possible to describe all these broken symmetries within a single theory?  Here I describe a translational invariant magnetoelectric (ME) loop current order parameter which naturally arises out of pair density wave (PDW) order as an explanation for the pseudogap phase.

SUMMARY:Colloquium: Tomas M. Linz
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nModeling Binary Black Hole Systems with Black Hole Perturbation Theory\nTomas M. Linz\, PhD Candidate\, UWM Dept. of Physics  \nAccording to Einstein’s theory of general relativity\, systems of two or more bodies should emit an oscillating gravitational signal that we call a gravitational wave.  The detection and characterization of these waves would provide an enormous scientific benefit to the fields of astronomy\, cosmology\, and fundamental physics.  Unfortunately\, these signals are very weak\, so that in addition to needing extremely sensitive equipment\, we also need to have very accurate models of the waves created by the possible sources.  A physically compelling system for study is a system of two black holes with an extreme mass ratio; in this case it is natural to treat the smaller black hole as a point particle whose field perturbs that of the larger black hole.  The goal of my research is to create an accurate model of the point particle’s orbit by accounting for the force it feels from interacting with its own field\, which we call the gravitational self-force.  The calculation of the self-force is complicated by the fact that the point particle’s own field diverges at the location of the particle\, precisely where we need to evaluate it. \nIn this talk\, I will discuss how we overcame the inherent challenges in computing the self-force.  I will also discuss how\, with the aid of some recent results\, it will be possible to significantly reduce the computational time required to compute the gravitational self-force\, possibly to the point where we could generate self-force corrected trajectories and compute the resulting gravitational wave signals.

SUMMARY:Colloquium: Ionel Popa
DESCRIPTION:This special Physics department colloquium is scheduled for Thursday 4/30/15 at 4:00 pm in Room 135.  Coffee\, tea and cookies are served at 3:45 pm in the same room.  Anyone is welcome. \nUncovering the nano-mechanics of giant muscle protein titin using a novel single molecule approach\nDr. Ionel Popa\, Postdoctoral Research Scientist\, Department of Biological Sciences\, Columbia University\, New York\, NY \nCurrent theories of muscle contraction propose that the power of stroke of a myosin motor is the sole source of mechanical energy driving the sliding filaments of a contracting muscle.  These models exclude titin\, the largest protein in the human body\, which determines the passive elasticity of muscle tissue.  Using a technique developed during my postdoctoral training based on a combination of Halo Tag covalent attachment and magnetic tweezers\, we have discovered that titin Ig domains from the elastic I band region undergo unfolding/folding reactions at physiological forces of 6-8 pN.  The spontaneous folding contraction can take place at forces below 10 pN\, delivering up to 105 zJ of additional contractile energy\, a value larger than the mechanical energy delivered by the power stroke of a myosin motor.  Based on hour-long recording of single multidomain proteins investigated under force-clamp condition\, we have demonstrated a new approach of the construction of the free energy of a protein under force\, which includes the physics of extending the polypeptide.  The experimental and theoretical advances that I will present strongly suggest the need for the addition of a new force-generating element\, titin\, to the actomyosin theory of muscle contraction and provide a more realistic modeling for tissue elasticity.  Fully deciphering how proteins operate in vivo under force will be a critical area of research as this may provide key insights into developing new theories for muscular dystrophy\, cancer or misfolding diseases.

SUMMARY:Colloquium: Kendra King Frederick
DESCRIPTION:This special Physics department colloquium is scheduled for Monday 4/27/15 at 4:00 pm in Room 135.  Coffee\, tea and cookies are served at 3:45 pm in the same room.  Anyone is welcome. \nTowards in vivo NMR: Putting prions in context\nDr. Kendra King Frederick\, Postdoctoral Scholar\, Whitehead Institute\, Cambridge\, MA \nProtein folding and assembly into macromolecular structures happens in crowded environments with the coordinated participation of many biomolecules.  Yet\, limitations on the specificity and sensitivity of biophysical techniques typically restrict structural investigations to purified systems at concentrations that are orders of magnitude above endogenous levels.  I apply a sensitivity-enhancement technique for solid state Nuclear Magnetic Resonance spectroscopy (NMR)\, dynamic nuclear polarization\, to investigate a protein at endogenous concentrations in its native environment.  With the goal of understanding how proteins involved in human pathologies such as neurodegenerative diseases interact at both the atomic and molecular levels within cells\, work on the yeast prion protein establishes genetic\, biochemical and spectroscopic techniques that enable structural and mechanistic investigation of proteins in biologically relevant contexts.

SUMMARY:Colloquium: Dr. Anna Frebel
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nHunting the First Generations of Stars and Galaxies\nDr. Anna Frebel\, Associate Professor\, Dept. of Physics\, Massachusetts Institute of Technology  \nThe new Australian SkyMapper 1.3m telescope is carrying out a photometric survey of the entire Southern Sky.  From using an ugriz filter plus an additionally narrow filter placed at the Ca K line at 3933 Å\, stellar parameters can be obtained for all stars observed.  This allows for an efficient selection of a variety of stellar types\, including metal-poor stars.  Recent efforts to search for the most metal-poor stars have indeed delivered a new record holder the the most iron-poor star:  no iron lines were detected in the high-resolution follow-up Magellan spectrum and only an upper limit of [Fe/H]<-7.1 could be determined.  Contrary to its iron deficiency\, the star has a significant amount of carbon.  This abundance pattern can be explained with the star being a second-generation star in the universe which formed from a gas cloud enriched by only one PopIII first star.  What was the environment in which these early stellar generations formed?  A spectro-scopic study of the faintest dwarf galaxy Segue 1 has shed light on this question.  Given the chemical abundance patterns of some its only few stars (with metallicities ranging from -4<[Fe/H]<-1) suggest that this tiny galaxy may be a surviving first galaxy from the early universe. \nThis suggestion is in line with recent age measurements for similar ultra-faint dwarfs which showed these galaxies to be single-age stellar systems that are about as old as the universe itself.

DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nMeasuring the Neutron-Star Equation of State Using Advanced Gravitational-Wave Detectors\nLeslie E. Wade\, PhD Candidate\, UWM Dept. of Physics \nIt is widely anticipated that the first direct detections of gravitational waves will be made by advanced gravitational-wave detectors\, such as the two Laser Interferometer Gravitational-waves Observatories (LIGO) and Virgo interferometer.  Arguably the most promising source for ground-based interferometers are coalescing binary neutron stars (NSs).  NSs are stellar remnants resulting from the gravitational collapse of massive stars.  They are extremely dense objects whose radius is the size of Milwaukee but whose mass is roughly 1.5 times the mass of the Sun!  Through the detection of a coalescing binary NS system\, advanced gravitational detectors can measure certain properties of the system.  In particular\, they are capable of constraining the NS equation of state (EOS)\, which is highly unconstrained at present.  Much like how the Ideal Gas Law is an EOS relating state variables of an ideal gas\, the NS EOS is a relationship that relates state variables of a NS.  For instance\, the NS EOS can relate mass to radius and density to pressure. \nIn this talk\, I will explain how gravitational-wave detectors can measure EOS effects in binary NS systems\, and I will present a new method of directly measuring the NS EOS by estimating the parameters of a 4-piece polytropic model that matches theoretical EOS candidates to a few percent.  I will finish by discussing important sources of error in EOS measurements that is the last remaining obstacle in unlocking the secrets of the NS EOS through gravitational waves.

Anyone is welcome. \nHow Culture Helps or Hinders You and Your Colleagues\nDr. Edmund Bertschinger\, Dept. of Physics & The Institute Community & Equity Office\, Massachusetts Institute of Technology  \nCulture is the dark energy of our lives; it is an invisible force that shapes our environment for work and life.  Culture shapes climate\, and climate affects individual and group satisfaction and accomplishment.  A culture of exclusion is one that fails to recognize and correct for unconscious bias\, marginalization of out-group members\, privilege\, etc.  A culture of inclusion advances a respectful and caring community to leverage the power of diversity\, improve employee success\, and enhance the quality of life for everyone. \nI will describe a study of community and culture at MIT\, and steps we have taken and are taking to create a culture of empowerment and respect for everyone.

SUMMARY:Colloquium: Lucianne Walkowicz
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nAstrobiology and Anomalies: Applications of Machine Learning in Astronomical Surveys\nDr. Lucianne Walkowicz\, Adler Planetarium \nSince its launch in 2009\, NASA’s Kepler Mission has transformed our knowledge of exoplanetary system demographics.  Kepler’s primary mission goal — to quantify the occurrence rate of habitable zone Earth-size planets around Sun-like stars — has a clear connection to astrobiology.  However\, in addition to its planet-finding capabilities\, the Kepler data may also be used to study other questions of astrobiological interest. \nIn this talk\, I will discuss my work on two such ongoing projects; the quantification of the stellar flare rate\, which influences planetary habitability through its influence on atmospheric photochemistry and escape; and the detection of anomalous stellar variability as a form of signal-agnostic optical SETI.  Both of these lines of research employ machine learning techniques\, making them applicable to the current and future datasets that now dominate the astronomical landscape.

SUMMARY:Colloquium: Dr. Bangalore S. Sathyaprakash
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135. Coffee and cookies are served at 2:45 pm in the same room. Anyone is welcome. \nThe Two-Body Problem a Century After Einstein\nDr. Bangalore S. Sathyaprakash\, School of Physics & Astronomy\, Cardiff University \nThe two-body problem is exactly solvable in Newtonian gravity but no such solution exists in Einstein’s theory of gravity. It is necessary to employ approximate methods and numerical simulations to understand the two-body dynamics. The past three decades have seen remarkable progress in Einstein’s theory of gravity which have helped unearth a lot of interesting effects. \nIn this talk I will examine recent advances and future challenges in understanding the dynamics of binary black holes and neutron stars\, and how observation of gravitational waves from such systems can impact our insight into fundamental physics\, astrophysics and cosmology.

DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135. Coffee and cookies are served at 2:45 pm in the same room. Anyone is welcome. \nLSST: Physicists and Astronomers of the World\, Unite!\nDr. Željko Ivezić\, Professor of Astronomy/LSST Project Scientist\, University of Washington \nThe Large Synoptic Survey Telescope (LSST) will be the most comprehensive optical sky survey project ever undertaken. LSST will take panoramic images of the entire sky twice each week for 10 years\, resulting in what can be called “the greatest movie of all time.” The resulting hundreds of petabytes of imaging data for close to 40 billion objects will be used for investigations ranging from cataloging dangerous near-Earth asteroids to fundamental physics such as characterization of dark matter and dark energy. \nI will overview LSST science drivers and system design and then discuss the main methods for studying Dark Universe. As an illustration of related ongoing work\, I will describe determination of the Milky Way dark matter halo properties using data obtained by SDSS. I will also briefly comment on how to efficiently prepare our students to be ready for this Big Data era.

Anyone is welcome. \nThe Promise and Perils of Proton Therapy in the War on Cancer\nDr. Brian Tonner\, Dept. of Radiation Oncology\, Moffitt Cancer Center (Tampa\, FL) \nThe latest weapon in the arsenal of cancer therapy is Proton Therapy\, which uses intense beams of protons in the 100-250 MeV energy range to kill cancer tumors. There are sound\, fundamental physical reasons for expecting proton therapy to exceed other radiation therapy methods in effectiveness\, but its implementation has been met with unforeseen difficulties\, and even controversy. My research has considered the application of a method from condensed matter physics\, Proton Induced X-ray Emission or PIXE\, to address some of the difficulties faced in having proton therapy achieve its true promise. \nThis talk will discuss the background and application of proton therapy to cancer treatment from a physics perspective.

SUMMARY:Colloquium: Dr. Maura McLaughlin
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135. Coffee and cookies are served at 2:45 pm in the same room. Anyone is welcome. \nA Galactic Scale Gravitational Wave Obervatory\nDr. Maura McLaughlin\, Professor of Physics and Astronomy\, West Virginia University\nPhysics – Room 481 \nPulsars are rapidly rotating neutron stars with phenomenal rotational stability that can be used as celestial clocks in a variety of fundamental physics experiments. One of these experiments involves using an array of precisely timed millisecond pulsars to detect perturbations due to gravitational waves. The gravitational waves detectable through pulsar timing will most likely result from an ensemble of supermassive black hole binaries. I will describe the efforts of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav)\, a collaboration which monitors an array of over 40 millisecond pulsars with the Green Bank Telescope and Arecibo Observatory. The most recent limits on various types of gravitational wave sources will be presented\, and I will show how these limits are already constraining models for galaxy formation and evolution and the tension of cosmic strings. \nI will then describe the dramatic gains in sensitivity that are expected from discoveries of millisecond pulsars\, more sensitive instrumentation\, im-proved detection algorithms\, and international collaboration and show that detection is possible before the end of the decade.

SUMMARY:Colloquium: Dr. Leonard Parker
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135. Coffee and cookies are served at 2:45 pm in the same room. Anyone is welcome. \nThe Creation of Bosons\, Fermions\, Gravitational Perturbations and Waves in the Expanding Universe\nDr. Leonard Parker\, Distinguished Professor Emeritus\, UW-Milwaukee\, Dept. of Physics\nPhysics – Room 481 \nQuantum field theory predicts that particles\, perturbations and gravitational waves may be created from the vacuum in an expanding universe. The quantum field theory basis for this particle creation from vacuum was first shown and thoroughly studied in my Ph.D. Thesis (Harvard University\, 1966) and my related papers (Phys. Rev. Lett\,\, 1968\, and Phys. Rev. 1969 and 1971). I go over the physical basis for these processes that follow from quantum field theory and general relativity. The effect of the creation of perturbations and particles is observed today in the small temperature anisotropies of the isotropic CMB radiation. Furthermore\, part of the recently observed B-wave polarization pattern of the CMB radiation may result from the creation of gravitational wave perturbations by the early expanding universe. \nFinally\, I discuss the quantum field theory basis for the vacuum state of the exponentially expanding inflationary universe. I show how the inflationary vacuum state may arise by dynamical evolution from an initial Minkowski vacuum state in a flat space-time that spontaneously fluctuates to form some subregions undergoing inflationary exponential expansion.

SUMMARY:Colloquium: Justin Ellis
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nSearching for Gravitational Waves With Pulsar Timing Arrays\nJustin Ellis\, PhD Candidate\, UWM Dept. of Physics \nGravitational Waves (GWs) are tiny ripples in the fabric of space-time predicted by Einstein’s theory of General Relativity.  Pulsar timing arrays (PTAs) offer a unique opportunity to detect low frequency GWs in the near future.  Such a detections would be complementary to both LISA and LIGO GW efforts.  In this frequency band\, the expected source of GWs are Supermassive Black Hole Binaries (SMBHBs) and they will most likely form in an ensemble creating a stochastic GW background with the possibility of a few nearby/massive sources that will be individually resolvable.  A direct detection of GWs will open a new window into the fields of astronomy and astrophysics by allowing us to constrain the coalescence rate of SMBHBs\, providing further tests on the theory of General Relativity\, and giving us access to properties of black holes not accessible by current astronomical techniques. \nThis dissertation work focuses primarily on the development of several robust data analysis pipelines for the detection and characterization of continuous GWs and a stochastic GW background.  The data analysis problem for PTAs is quite diffficult as one must fully take into account the timing model that must be fit in order to obtain the residuals\, uneven sampling (including large gaps)\, and potential red noise processes.  The data analysis techniques presented here can handle all of these effects completely while allowing additional freedom in parameterizing the noise present in the data.  The accumulation of work from this dissertation has resulted in a fully functional\, robust\, and efficient data analysis pipeline that has been successfully applied to the 5- and 9-year NANOGrav data releases.

Anyone is welcome. \nMapping Dynamic Nature of Molecular Machines that constitute Life\nDr. Peter Schwander\, Senior Scientist\, UW-Milwaukee (Tampa\, FL) \nFighting disease and maintaining life requires a good understanding of the machinery inside living cells.  These biological molecular machines go permanently through many conformational states\, and each state is structurally only slightly different from the previous one.  Single-particle methods take individual snapshots of molecules\, one at a time.  Single-particle methods thus avoid averaging over states and are therefore ideally suited to study conformations.  When  successful\, this allows compiling 3D movies of molecular machines at work. \nA novel analytic approach\, based on manifold embedding\, allows model-free\, quantitative analysis of the degrees of freedom and the energy landscape underlying continuous conformational changes from single-particle methods.  This approach has been successfully applied to snapshots of the eukaryotic ribosome taken with a cryogenetic electron microscope (cryoEM).  The results constitute the first direct evidence of the intersubunit rotation in three dimensions\, and suggest the ribosome to act like a Brownian ratchet. \nSimilar to cryoEM\, the emerging X-ray Free Energy Laser (XFEL) allows taking snapshots from single molecules before the intense beam destroys them\, XFEL thus provides a new source of single-particle snapshots to study conformations and will complement the more established cryoEM in the near future.

DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nComputational Methods for Protein Structure Prediction\, Protein Dynamics and Drug Discovery\nDr. Steffen Lindert\, Post Doctoral Researcher\, Department of Pharmacology\, University of California-San Diego \nComputational methods are very useful for investigating biological systems. In addition to simulating molecular scale events that may not be probed easily by experiment\, simulations can also inform experiments and vice versa.  Here\, three main computational methods are applied to probe biological processes and systems: molecular dynamics\, de novo protein structure prediction using sparse experimental restraints\, and computer-aided drug discovery.  More specifically\, molecular dynamics methods are used to investigate the opening and closing properties of the hydrophobic patch in Troponin C\, an important process in the contraction of heart muscle cells.  Furthermore\, the development of EM-Fold\, a software tool to fold proteins into medium resolution cryoEM density maps is presented. EM-Fold is able to predict the structure of large helical proteins with atomic detail.  Finally\, the relaxed complex scheme\, a computer-aided drug discovery method accounting for receptor flexibility\, was used to find potent inhibitions of two enzymes involved in bacterial cell wall synthesis.  The lead compound was shown to be effective in animal models and to have synergistic activity with methicillin.

DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135.  Coffee and cookies are served at 2:45 pm in the same room.  Anyone is welcome. \nThe Physics of the Games Cancer Plays\nDr. Robert H. Austin\, Department of Physics\, Princeton University \nCancer is a complex condition with strong ecological elements\, often consisting of stromal cells as well as cancer cells.  Stromal cell provide protection from drug-induced apoptosis in cancer via secreting growth signals and further mediate cancer cell growth and survival under treatment.  I’ll talk about a microfluidic ecology which mimics the bone marrow ecology under chemotherapy\, including extracellular matrix and stromal cells\, drug gradients\, and weakly connected micro-habitats\, to visualize the dynamics of multiple myeloma and stromal cell interactions and the emergence of resistance.  We model the observed spatial dynamics of emergent resistance using spatial evolutionary game theory\, with (i) fitness as a function of population composition and drug concentration\, and  (ii) spatial coupling via diffusive migration and fitness-driven migration of the cells. \nI’ll show that the spatial structure of a complex microecology and the stress of chemotherapy transforms a prisoner’s dilemma into a coordination game\, and enables the coexistence of multiple myeloma and stromal cells within the drug gradient\, and show that evolutionary game theory applied to two interacting cell populations can yield quantitative prediction of future densities of the two cell populations based on their fitness as a function of population composition.  I believe that evolutionary game theory successfully predicts the future densities of strains of bone marrow stromal and cancer cells\, and opens the possible clinical use of such analysis for predicting and controlling cancer progression.

SUMMARY:Colloquium: Dr. Zhong Ren
DESCRIPTION:The Physics department colloquia are usually on Friday afternoons at 3 pm in Room 135. Coffee and cookies are served at 2:45 pm in the same room. Anyone is welcome. \nMechanics and Dynamics of Protein Structures\nDr. Zhong Ren\, CEO-Renz Research \nMy research integrates experimental and computational approaches in dynamic crystallography to study mechanics and dynamics during protein function.  I will present an example to illustrate how a K+ channels gating ring achieves its function for clean opening and closing.  I will also present a recent study on the cooperative mechanism of human hemoglobin (doi:10.1371/journal.pone.0077141 and ~363) and demonstrate how a structural meta-analysis is employed to extract structural dynamics from increasingly abundant entries in the Protein Data Bank.  I will show several experimental and computational advances that would suit different types of protein crystals in dynamic studies\, which include light sensitive systems such as photoreceptors and light inert enzymes.  Finally\, I will propose a viable technical route to push time resolution of single crystal diffraction down to sub-ps using XFEL sources and speculate on what kind of structural signal that could be captured.  The structural changes we have recently observed in a simpler hemoglobin from an invertebrate at 100 ps and a fraction of such synchrotron bunch provide confidence for future XFEL experiments.

Anyone is welcome. \nProbing Complex Materials One Atom at a Time by a Combination of Theory and Microscopy\nDr. Sokrates T. Pantelides\, University Distinguished Professor of Physics and Engineering\, Dept. of Physics and Astronomy & Dept. of Electrical Engineering & Computer Science\, Vanderbuilt University and Materials Science and Techonogy Division\, Oak Ridge National Laboratory \nCalculations based on density functional theory using high-performance computers have made enormous strides in describing the atomic-scale properties of complex materials.  In parallel\, aberration-corrected scanning transmission electron microscopy has reached extraordinary levels of spatial and energy resolution\, in both imaging and electron-energy-loss spectroscopy.  The combination of theory and microscopy provides an unparalleled probe to unravel the atomic-scale processes that control vital properties for electronic\, optoelectronic\, and energy-related applications.  Your are invited to a journey through the wide world of complex materials structures – semiconductors\, superconductors\, complex oxides\, graphene\, ultrasmall nanoparticles – for a first-hand experience of the nanoscale. \nResearch supported by DOE Basic Energy Sciences; primary collaborator; Steve Pennycook (formerly at ORNL).
