  • Wang, Z. T.; Pan, J.; Li, Y.; Schuh, Christopher A. (American Physical Society, 2013-09)
    The deformation of metallic glasses involves two competing processes: a disordering process involving dilatation, free volume accumulation, and softening, and a relaxation process involving diffusional ordering and ...
  • Chen, Jiahao; Van Voorhis, Troy; Welborn, Matthew Gregory (American Physical Society, 2013-11)
    We investigate how free probability allows us to approximate the density of states in tight-binding models of disordered electronic systems. Extending our previous studies of the Anderson model in one dimension with ...
  • Zhang, Xueyan; Nepf, Heidi (American Geophysical Union, 2008-08)
    Differences in water density can drive an exchange flow between the vegetated and open regions of surface water systems. A laboratory experiment has been conducted to investigate this exchange flow, using a random array ...
  • Radtke, G.; Saul, Alberto Andres (American Physical Society, 2014-03)
    Density functional calculations have been carried out to investigate the microscopic origin of the magnetic properties of β-TeVO[subscript 4]. Two different approaches, based either on a perturbative treatment of the ...
  • Faraone, Antonio; Kamitakahara, William A.; Liu, Kao-Hsiang; Mou, Chung-Yuan; Leão, Juscelino B.; Chang, Sung; Zhang, Yang; Chen, Sow-Hsin (Proceedings of the National Academy of Sciences (PNAS), 2011-06)
    A neutron scattering technique was developed to measure the density of heavy water confined in a nanoporous silica matrix in a temperature-pressure range, from 300 to 130 K and from 1 to 2,900 bars, where bulk water will ...

  • Movassagh, Ramis; Edelman, Alan (American Physical Society, 2011-08)
    We propose a method that we call isotropic entanglement (IE), which predicts the eigenvalue distribution of quantum many body (spin) systems with generic interactions. We interpolate between two known approximations by ...
  • Reinke, Matthew Logan; Rice, John E.; White, Anne E.; Greenwald, Martin J.; Howard, Nathaniel Thomas; Ennever, Paul Chappell; Hubbard, Amanda E.; Hughes, Jerry W.; Gao, Chi (IOP Publishing, 2013-01)
    The physical mechanisms that cause tokamak plasmas to rotate toroidally without external momentum input are of considerable interest to the plasma physics community. This paper documents a substantial change in both the ...
  • Halpern, Illan F.; Joss, Matthew Albert Henry; Sfakianakis, Evangelos I.; Hertzberg, Mark Peter (Elsevier, 2015-07)
    Hybrid inflation models are especially interesting as they lead to a spike in the density power spectrum on small scales, compared to the CMB, while also satisfying current bounds on tensor modes. Here we study hybrid ...
  • Kang, Eunsuk; Jackson, Daniel (Institute of Electrical and Electronics Engineers, 2010-11)
    An approach is suggested for arguing that a system is dependable. The key idea is to structure the system so that critical requirements are localized in small, reliable subsets of the system's components called trusted ...
  • Abernathey, Ryan Patrick; Marshall, John C.; Ferreira, David (American Meteorological Society, 2011-12)
    An eddy-resolving numerical model of a zonal flow, meant to resemble the Antarctic Circumpolar Current, is described and analyzed using the framework of J. Marshall and T. Radko. In addition to wind and buoyancy forcing ...
  • Feng, Wen; Crawley, Edward F.; de Weck, Olivier L.; Keller, Rene; Robinson, Bob (Design Society, 2010)
    This paper develops a qualitative/quantitative network approach, namely a “Stakeholder Value Network”, to understand the impacts of both direct and indirect relationships between stakeholders on the success of large ...
  • Fox, Jacob; Sudakov, Benny (Wiley Blackwell (John Wiley & Sons), 2010-11)
    We describe a simple and yet surprisingly powerful probabilistic technique which shows how to find in a dense graph a large subset of vertices in which all (or almost all) small subsets have many common neighbors. Recently ...
  • Lamming, Dudley W.; Mihaylova, Maria M.; Katajisto, Pekka; Baar, Emma L.; Yilmaz, Omer; Hutchins, Amanda W.; Gultekin, Yetis; Gaither, Rachel P.; Sabatini, David M. (Anatomical Society/John Wiley & Sons, Inc, 2014-07)
    Rapamycin, an inhibitor of the mechanistic target of rapamycin (mTOR), robustly extends the lifespan of model organisms including mice. We recently found that chronic treatment with rapamycin not only inhibits mTOR complex ...
  • Hajiaghayi, Mohammad Taghi; Bredin, Jonathan L.; Demaine, Erik D.; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-02)
    We consider the problem of deploying or repairing a sensor network to guarantee a specified level of multipath connectivity (k-connectivity) between all nodes. Such a guarantee simultaneously provides fault tolerance against ...
  • Liu, Tianshu; Nink, Jacob; Merati, Parviz; Tian, Tian; Li, Yong; Shieh, Tom (Springer Science + Business Media B.V., 2009-12)
    The fluid mechanics of the deposition of micron liquid (olive oil) droplets on a glass wall in an impinging turbulent air jet is studied experimentally. The spatial patterns of droplets deposited on a wall are measured by ...
  • Lanman, Douglas R.; Wetzstein, G.; Hirsch, M.; Raskar, Ramesh (IOP Publishing, 2013-02)
    With the re-emergence of stereoscopic displays, through polarized glasses for theatrical presentations and shuttered liquid crystal eyewear in the home, automultiscopic displays have received increased attention. Commercial ...
  • Rubner, Michael F.; Cohen, Robert E.; Gilbert, Jonathan Brian (National Academy of Sciences (U.S.), 2013-04)
    Functional organic thin films often demand precise control over the nanometer-level structure. Interlayer diffusion of materials may destroy this precise structure; therefore, a better understanding of when interlayer ...
  • Fabbri, Filippo; Smith, Matthew J.; Recht, Daniel; Aziz, Michael J.; Salviati, Giancarlo; Gradecak, Silvija (American Institute of Physics (AIP), 2013-01)
    We investigate the luminescence of Si supersaturated with S (Si:S) using depth-resolved cathodoluminescence spectroscopy and secondary ion mass spectroscopy as the S concentration is varied over 2 orders of magnitude ...
  • Srinivasan, Vivek J.; Sakadžic, Sava; Gorczynska, Iwona; Ruvinskaya, Svetlana; Wu, Weicheng; Fujimoto, James G.; Boas, David A. (Optical Society of America, 2009-10)
    We describe depth-resolved microscopy of cortical hemodynamics with high-speed spectral/Fourier domain optical coherence tomography (OCT). Stimulus-evoked changes in blood vessel diameter, flow, and total hemoglobin were ...
