    • Locally testable codes and cayley graphs 

      Gopalan, Parikshit; Vadhan, Salil P.; Zhou, Yuan (ACM Press, 2014)
      We give two new characterizations of ( 2-linear, smooth) locally testable error-correcting codes in terms of Cayley graphs over Fh2: * A locally testable code is equivalent to a Cayley graph over h2 whose set of generators ...

    • Locating a Small Cluster, Privately 

      Nissim, Kobbi; Stemmer, Uri; Vadhan, Salil P. (ACM, 2016)
      We present a new algorithm for locating a small cluster of points with differential privacy [Dwork, McSherry, Nissim, and Smith, 2006]. Our algorithm has implications to private data exploration, clustering, and removal ...

    • Locating Particles Accurately in Microscope Images Requires Image-Processing Kernels to be Rotationally Symmetric 

      Lu, Peter James; Shutman, Maor; Sloutskin, Eli; Butenko, Alexander V. (Optical Society of America, 2013)
      Computerized image-analysis routines deployed widely to locate and track the positions of particles in microscope images include several steps where images are convolved with kernels to remove noise. In many common ...

    • Location choice in two-sided markets with indivisible agents 

      Anderson, Robert M.; Ellison, Glenn; Fudenberg, Drew (Elsevier BV, 2010)
      Consider a model of location choice by two sorts of agents, called “buyers” and “sellers”: In the first period agents simultaneously choose between two identical possible locations; following this, the agents at each ...

    • Location of atoms in the first monolayer of GaAs on Si 

      Patel, J. R.; Freeland, P. E.; Hybertsen, M. S.; Jacobson, D. C.; Golovchenko, Jene Andrew (American Physical Society (APS), 1987)
      The position of Ga and As atoms at monolayer coverages of heteroepitaxial GaAs on clean Si(111) have been measured by x-ray standing waves in UHV. Though both As and Ga are incident on the surface As atoms choose to occupy ...

    • The location of ethnic and racial groups in the United States 

      Lieberson, Stanley; Waters, Mary C. (Wiley-Blackwell, 1987)

    • Location of the bow shock ahead of cloud G2 at the Galactic Centre 

      Sadowski, A.; Narayan, Ramesh; Sironi, L.; Ozel, F. (Oxford University Press (OUP), 2013)
      We perform detailed magnetohydrodynamic simulations of the gas cloud G2 interacting with the accretion flow around the Galactic Center black hole Sgr A∗ . We take as our initial conditions a steady-state, converged solution ...

    • A location-dependent runs-and-gaps model for predicting TCP performance over a UAV wireless channel 

      Kung, H. T.; Lin, Chit-Kwan; Lin, Tsung-Han; Tarsa, Stephen John; Vlah, Dario; Hague, Daniel; Muccio, Michael; Poland, Brendon; Suter, Bruce (IEEE, 2010)
      In this paper, we use a finite-state model to predict the performance of the Transmission Control Protocol (TCP) over a varying wireless channel between an unmanned aerial vehicle (UAV) and ground nodes. As a UAV traverses ...

    • The Locations of Short Gamma-Ray Bursts as Evidence for Compact Object Binary Progenitors 

      Fong, W; Berger, Edo (IOP Publishing, 2013)
      We present a detailed investigation of Hubble Space Telescope rest-frame UV/optical observations of 22 short gamma-ray burst (GRB) host galaxies and sub-galactic environments. Utilizing the high angular resolution and depth ...

    • Locking of El Nino’s Peak Time to the End of the Calendar Year in the Delayed Oscillator Picture of ENSO 

      Tziperman, Eli; Cane, Mark A.; Zebiak, Stephen E.; Xue, Yan; Blumenthal, B. (American Meteorological Society, 1998)
      El Niño events owe their name to their tendency to be locked to the seasonal cycle. A simple explanation is proposed here for the locking of the peak of ENSO’s basin-scale warming to the end of the calendar year. The ...

    • Locking the genome: nuclear organization and cell fate 

      Meister, Peter; Mango, Susan; Gasser, Susan M (Elsevier BV, 2011)
      The differentiation of pluripotent or totipotent cells into various differentiated cell types is accompanied by a restriction of gene expression patterns, alteration in histone and DNA methylation, and changes in the gross ...

    • Locomotor function of the dorsal fin in rainbow trout: kinematic patterns and hydrodynamic forces 

      Drucker, E. G.; Lauder, George V. (The Company of Biologists, 2005)
      In this study, we examine the kinematics and hydrodynamics of the soft dorsal fin in a representative basal teleost, the rainbow trout (Oncorhynchus mykiss), during steady rectilinear locomotion at 0.5–2.0 body lengths ...

    • The Locus of Ergative Case Assignment: Evidence from Scope 

      Anand, Pranav; Nevins, Andrew Ira (Springer, 2006)

    • The Locus of Evolution: Evo Devo and the Genetics of Adaptation 

      Hoekstra, Hopi E.; Coyne, Jerry A. (Wiley-Blackwell, 2007)
      An important tenet of evolutionary developmental biology (“evo devo”) is that adaptive mutations affecting morphology are more likely to occur in the cis-regulatory regions than in the protein-coding regions of genes. This ...

    • Log or Linear? Distinct Intuitions of the Number Scale in Western and Amazonian Indigene Cultures 

      Dehaene, Stanislas; Izard, Véronique; Spelke, Elizabeth S.; Pica, Pierre (American Association for the Advancement of Science, 2008)
      The mapping of numbers onto space is fundamental to measurement and to mathematics. Is this mapping a cultural invention or a universal intuition shared by all humans regardless of culture and education? We probed number-space ...

    • Logarithmic corrections to black hole entropy from Kerr/CFT 

      Pathak, Abhishek; Porfyriadis, Achilleas P.; Strominger, Andrew; Varela, Oscar (Springer Verlag, 2017)
      It has been shown by A. Sen that logarithmic corrections to the black hole area-entropy law are entirely determined macroscopically from the massless particle spectrum. They therefore serve as powerful consistency checks ...
