    • Slow light enhanced singlet exciton fission solar cells with a 126% yield of electrons per photon 

      Thompson, Nicholas J.; Goldberg, David; Menon, Vinod M.; Baldo, Marc A.; Congreve, Daniel Norbert (Association for Computing Machinery (ACM), 2013-12)
      Singlet exciton fission generates two triplet excitons per absorbed photon. It promises to increase the power extracted from sunlight without increasing the number of photovoltaic junctions in a solar cell. We demonstrate ...
    • Slow Moving Debt Crises 

      Lorenzoni, Guido; Werning, Ivan (American Economic Association, 2019-09)
      We study slow moving debt crises: self-fulfilling equilibria in which high interest rates, due to the fear of a future default, lead to a gradual but faster accumulation of debt, ultimately validating investors’ fear. We ...
    • Slow scrambling in disordered quantum systems 

      Swingle, Brian; Chowdhury, Debanjan (American Physical Society, 2017-02)
      In this work we study the effect of static disorder on the growth of commutators—a probe of information scrambling in quantum many-body systems—in a variety of contexts. We find generically that disorder slows the onset ...
    • Slow-γ Rhythms Coordinate Cingulate Cortical Responses to Hippocampal Sharp-Wave Ripples during Wakefulness 

      Remondes, Miguel; Wilson, Matthew A.; Wilson, Matthew A. (Elsevier, 2015-11)
      Behavioral changes in response to reward require monitoring past behavior relative to present outcomes. This is thought to involve a fine coordination between the hippocampus (HIPP), which stores and replays memories of ...
    • Slower recovery in space before collapse of connected populations 

      Dai, Lei; Korolev, Kirill Sergeevich; Gore, Jeff (Nature Publishing Group, 2012-11)
      Slower recovery from perturbations near a tipping point and its indirect signatures in fluctuation patterns have been suggested to foreshadow catastrophes in a wide variety of systems. Recent studies of populations in the ...
    • Slowing of Magnetic Reconnection Concurrent with Weakening Plasma Inflows and Increasing Collisionality in Strongly Driven Laser-Plasma Experiments 

      Fox, W.; Stoeckl, C.; Li, Chikang; Zylstra, Alex Bennett; Seguin, Fredrick Hampton; e.a. (American Physical Society, 2015-05)
      An evolution of magnetic reconnection behavior, from fast jets to the slowing of reconnection and the establishment of a stable current sheet, has been observed in strongly driven, β ≲ 20 laser-produced plasma experiments. ...
    • A SLOWLY EVOLVING HOST MOVES FIRST IN SYMBIOTIC INTERACTIONS 

      Damore, James A.; Gore, Jeff (Wiley Blackwell, 2011-04)
      Symbiotic relationships, both parasitic and mutualistic, are ubiquitous in nature. Understanding how these symbioses evolve, from bacteria and their phages to humans and our gut microflora, is crucial in understanding how ...
    • Slowly reducible genetically encoded green fluorescent indicator for in vivo and ex vivo visualization of hydrogen peroxide 

      Piatkevich, Kiryl (Multidisciplinary Digital Publishing Institute, 2019-06-27)
      Hydrogen peroxide (H2O2) plays an important role in modulating cell signaling and homeostasis in live organisms. The HyPer family of genetically encoded indicators allows the visualization of H2O2 dynamics in live cells ...
    • Slug and Sox9 Cooperatively Determine the Mammary Stem Cell State 

      Guo, Wenjun; Keckesova, Zuzana; Donaher, Joana Liu; Shibue, Tsukasa; Tischler, Verena; e.a. (Elsevier, 2012-03)
      Regulatory networks orchestrated by key transcription factors (TFs) have been proposed to play a central role in the determination of stem cell states. However, the master transcriptional regulators of adult stem cells are ...
    • The SM protein Sly1 accelerates assembly of the ER-Golgi SNARE complex 

      Demircioglu, Fatma Esra; Fasshauer, Dirk; Burkhardt, Pawel (National Academy of Sciences (U.S.), 2014-09)
      Soluble N-ethylmaleimide–sensitive factor attachment protein receptor (SNARE) and Sec1/Munc18 (SM) proteins constitute the core of an ancient vesicle fusion machine that diversified into distinct sets that now function in ...
    • Small and Large Ribosomal Subunit Deficiencies Lead to Distinct Gene Expression Signatures that Reflect Cellular Growth Rate 

      Mertins, Philipp; Regev, Aviv (Elsevier BV, 2019-01)
      In this issue of Molecular Cell, Cheng et al. report specific and dose-dependent gene expression changes resulting from decreased ribosome levels, including distinct gene expression signatures resulting from loss of genes ...
    • Small and lightweight laser retro-reflector arrays for lunar landers 

      Sun, Xiaoli; Smith, David Edmund; Hoffman, Evan D.; Wake, Shane W.; Cremons, Daniel R.; e.a. (The Optical Society, 2019-11)
      A set of small and lightweight laser retro-reflector arrays (LRAs) was fabricated and tested for use on lunar landers under NASA’s Commercial Lunar Payload Service program. Each array contains eight 1.27-cm-diameter corner ...
    • Small and strong formulations for unions of convex sets from the Cayley embedding 

      Vielma Centeno, Juan Pablo (Springer Nature America, Inc, 2018-03)
      There is often a significant trade-off between formulation strength and size in mixed integer programming (MIP). When modelling convex disjunctive constraints (e.g. unions of convex sets) this trade-off can be resolved by ...
    • The small binary asteroid (939) Isberga 

      Carry, B.; Matter, A.; Scheirich, P.; Pravec, P.; Molnar, L.; e.a. (Elsevier, 2014-11)
      In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic quantity. We aim here at characterizing the surface composition, mutual orbit, size, mass, and density of ...
    • Small Business Applications of Sourcemap: A Web Tool for Sustainable Design and Supply Chain Transparency 

      Bonanni, Leonardo Amerigo; Hockenberry, Matthew; Csikszentmihalyi, Chris; Ishii, Hiroshi; Zwarg, David (Association for Computing Machinery, 2010-04)
      This paper introduces sustainable design applications for small businesses through the Life Cycle Assessment and supply chain publishing platform Sourcemap.org. This webbased tool was developed through a year-long ...
    • Small distance expansion for radiative heat transfer between curved objects 

      Golyk, Vladyslav A.; Krueger, Matthias Helmut Guenter; McCauley, Alexander Patrick; Kardar, Mehran (Institute of Physics Publishing, 2013-02)
      We develop a small distance expansion for the radiative heat transfer between gently curved objects, in terms of the ratio of distance to radius of curvature. A gradient expansion allows us to go beyond the lowest-order ...
    • Small forces and large firms: Foundations of the RBV 

      Wernerfelt, Birger (John Wiley & Sons, Inc, 2013-06)
      This paper was originally prepared as a basis for a lecture when I received an honorary doctorate at the Copenhagen Business School. I am grateful to Nicolai Foss for suggesting that I pursue independent publication to ...
    • Small genomic insertions form enhancers that misregulate oncogenes 

      Hnisz, Denes; Li, Zhaodong; Weichert-Leahey, Nina; Rahman, Sunniyat; Liu, Yu; e.a. (Nature Publishing Group, 2017-06-20)
      The non-coding regions of tumour cell genomes harbour a considerable fraction of total DNA sequence variation, but the functional contribution of these variants to tumorigenesis is ill-defined. Among these non-coding ...
    • Small m[subscript ν] due to R-symmetry breaking for small Λ 

      Davies, Rhys; McCullough, Matthew P. (American Physical Society, 2012-07)
      We describe a class of supersymmetric models in which neutrinos are kept light by an R-symmetry. In supergravity, R-symmetry must be broken to allow for a small cosmological constant after supersymmetry breaking. In the ...
    • Small mass plunging into a Kerr black hole: Anatomy of the inspiral-merger-ringdown waveforms 

      Taracchini, Andrea; Buonanno, Alessandra; Khanna, Gaurav; Hughes, Scott A. (American Physical Society, 2014-10)
      We numerically solve the Teukolsky equation in the time domain to obtain the gravitational-wave emission of a small mass inspiraling and plunging into the equatorial plane of a Kerr black hole. We account for the dissipation ...
