  • Halilov, Samed; Ashman, Christopher R.; Hellberg, C. Stephen (American Physical Society, 2010-07)
    We present a density-functional theory investigation of strained Ca[subscript 0.5]Sr[subscript 0.5]TiO[subscript 3] (CSTO). We have determined the structure and polarization for a number of arrangements of Ca and Sr in a ...
  • Garrity, Kevin; Kakekhani, Arvin; Ismail-Beigi, Sohrab; Kolpak, Alexie M. (American Physical Society, 2013-07)
    Ferroelectric surfaces provide a promising method for modifying surface reactions via an external electric field, which can potentially provide an avenue for tunable molecular binding and surface catalysis. Using ...
  • Wioland, Hugo; Woodhouse, Francis G.; Goldstein, Raymond E.; Dunkel, Joern (2016-01)
    Despite their inherently non-equilibrium nature [1], living systems can self-organize in highly ordered collective states [2, 3] that share striking similarities with the thermodynamic equilibrium phases [4, 5] of conventional ...
  • Parolari, Anthony Joseph; Goulden, M. L.; Bras, Rafael L. (American Geophysical Union (AGU), 2012-04)
    Nitrogen limits leaf gas exchange, canopy development, and evapotranspiration in many ecosystems. In dryland ecosystems, it is unclear whether increased anthropogenic nitrogen inputs alter the widely recognized dominance ...
  • Schwartz, Ernst; Kasprian, Gregor; Gruber, Gerlinde M.; Prayer, Daniela; Langs, Georg; Jakab, András; Schöpf, Veronika (Frontiers Research Foundation, 2014-10)
    The functional connectivity architecture of the adult human brain enables complex cognitive processes, and exhibits a remarkably complex structure shared across individuals. We are only beginning to understand its heterogeneous ...
  • Chou, Song; Flygare, Johan; Lodish, Harvey F. (Elsevier, 2013-02)
    We have developed a coculture system that establishes DLK[superscript +] fetal hepatic progenitors as the authentic supportive cells for expansion of hematopoietic stem (HSCs) and progenitor cells. In 1-week cultures ...
  • Chou, Song; Lodish, Harvey F. (National Academy of Sciences, 2010-03)
    Previously we showed that the ~2% of fetal liver cells reactive with an anti-CD3ε monoclonal antibody support ex vivo expansion of both fetal liver and bone marrow hematopoietic stem cells (HSCs); these cells express two ...
  • Young, David Y.; Young, John D.; Martel, Jan; Wu, Cheng-Yeu (Public Library of Science, 2009-11)
    Serum-derived granulations and purported nanobacteria (NB) are pleomorphic apatite structures shown to resemble calcium granules widely distributed in nature. They appear to be assembled through a dual inhibitory-seeding ...
  • Surmeier, D. James; Graybiel, Ann M. (Elsevier, 2012-07)
    In this issue of Neuron, Threlfell et al. (2012) report that synchronous activation of cholinergic interneurons evokes striatal dopamine release by activating presynaptic nicotinic acetylcholine receptors. These findings ...
  • Sheffer, Adam; de Zeeuw, Frank; Zahl, Joshua (Springer Berlin Heidelberg, 2014-10)
    We study the structure of planar point sets that determine a small number of distinct distances. Specifically, we show that if a set PP of n points determines o(n) distinct distances, then no line contains Ω(n[superscript ...
  • Bajcsy, Michal; Hofferberth, Sebastian; Balic, Vlatko; Peyronel, Thibault Michel Max; Zibrov, A. S.; Hafezi, Mohammad; Vuletic, Vladan; Lukin, M. D. (Society of Photo-Optical Instrumentation Engineers, 2009-02)
    Cold atoms confined inside a hollow-core photonic-crystal fiber with core diameters of a few photon wavelengths are a promising medium for studying nonlinear optical interactions at extremely low light levels. The high ...
  • Vuletic, Vladan; Peyronel, Thibault Michel Max; Lukin, M. D.; Zibrov, A. S.; Hafezi, Mohammad; Balic, Vlatko; Hofferberth, Sebastian; Bajcsy, Michal (The International Society for Optical Engineering, 2009-02)
    Cold atoms confined inside a hollow-core photonic-crystal fiber with core diameters of a few photon wavelengths are a promising medium for studying nonlinear optical interactions at extremely low light levels. The high ...
  • Ku, Mark Jen-Hao; Sommer, Ariel Tjodolv; Cheuk, Lawrence W.; Zwierlein, Martin Wolfram; Houcke, K. Van; Werner, F.; Kozik, E.; Prokofev, N.; Svistunov, B.; Schirotzek, A. (Nature Publishing Group, 2012-03)
    Precise understanding of strongly interacting fermions, from electrons in modern materials to nuclear matter, presents a major goal in modern physics. However, the theoretical description of interacting Fermi systems is ...
  • Raj, Bhiksha; Turicchia, Lorenzo; Schmidt-Nielsen, Bent; Sarpeshkar, Rahul (Hindawi Publishing Corporation, 2007-06)
    We describe an FFT-based companding algorithm for preprocessing speech before recognition. The algorithm mimics tone-to-tone suppression and masking in the auditory system to improve automatic speech recognition performance ...
  • Chen, Pei-Yu; Qin, Lingfeng; Barnes, Carmen; Charisse, Klaus; Yi, Tai; Zhang, Xinbo; Ali, Rahmat; Medina, Pedro P.; Yu, Jun; Slack, Frank J.; Kotelianski, Victor E.; Wang, Fen; Tellides, George; Simons, Michael; Anderson, Daniel Griffith (Elsevier, 2012-11)
    Maintenance of normal endothelial function is critical to various aspects of blood vessel function, but its regulation is poorly understood. In this study, we show that disruption of baseline fibroblast growth factor (FGF) ...
  • Delaware, Benjamin James; Pit-Claudel, Clement F.; Gross, Jason S.; Chlipala, Adam (Association for Computing Machinery, 2015-01)
    We present Fiat, a library for the Coq proof assistant supporting refinement of declarative specifications into efficient functional programs with a high degree of automation. Each refinement process leaves a proof trail, ...
  • Mekkaoui, Choukri; Huang, Shuning; Chen, Howard H.; Dai, Guangping; Reese, Timothy G; Kostis, William J; Thiagalingam, Aravinda; Maurovich-Horvat, Pal; Ruskin, Jeremy N; Hoffmann, Udo; Jackowski, Marcel P; Sosnovik, David (BioMed Central Ltd, 2012-10)
    Background: The study of myofiber reorganization in the remote zone after myocardial infarction has been performed in 2D. Microstructural reorganization in remodeled hearts, however, can only be fully appreciated by ...
  • Tsai, Tsung-Han; Zhou, Chao; Fujimoto, James G. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    An improved design for fiber bundle fluorescence endomicroscopy is demonstrated. Scanned illumination and detection using coherent fiber bundles with 30,000 elements with 3 μm resolution enables high speed imaging with ...
