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

Location of the bow shock ahead of cloud G2 at the Galactic Centre
(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
(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
(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
(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
(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
(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
(Springer, 2006) -
The Locus of Evolution: Evo Devo and the Genetics of Adaptation
(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 ... -
Locus-Dependent Epigenetic Inheritance of Polycomb-Mediated Gene Silencing
(2022-05-10)During development, it is crucial that gene expression patterns, which define cell phenotypes and “epigenetic states”, are stably inherited. The maintenance of epigenetic states involves changes in repressive histone ... -
Log or Linear? Distinct Intuitions of the Number Scale in Western and Amazonian Indigene Cultures
(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
(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 ... -
Logarithmic Singularities and Quantum Oscillations in Magnetically Doped Topological Insulators
(American Physical Society (APS), 2018-02-26)We report magnetotransport measurements on magnetically doped (Bi,Sb)2Te3 films grown by molecular beam epitaxy. In Hall bar devices, we observe logarithmic dependence of transport coefficients in temperature and bias ... -
Logarithmic Sobolev inequality for lattice gases with mixing conditions
(Springer Nature, 1996)Let μgcΛL,λμΛL,λgc denote the grand canonical Gibbs measure of a lattice gas in a cube of sizeL with the chemical potential γ and a fixed boundary condition. Let μcΛL,nμΛL,nc be the corresponding canonical measure defined ... -
Logarithmic Sobolev inequality for some models of random walks
(Institute of Mathematical Statistics, 1998)We determine the logarithmic Sobolev constant for the Bernoulli- Laplace model and the time to stationarity for the symmetric simple exclusion model up to the leading order. Our method for proving the logarithmic Sobolev ... -
Logging versus Soft Updates: Asynchronous Meta-data Protection in File Systems
(1999)The UNIX Fast File System (FFS) is probably the most widely-used file system for performance comparisons. However, such comparisons frequently overlook many of the performance enhancements that have been added over the ... -
Logic and Conversation Revisited: Evidence For a Division Between Semantic and Pragmatic Content in Real Time Language Comprehension
(Taylor & Francis, 2011-10-18)The distinction between semantics (linguistically encoded meaning) and pragmatics (inferences about communicative intentions) can often be unclear and counterintuitive. For example, linguistic theories argue that the meaning ... -
The logic in language: How all quantifiers are alike, but each quantifier is different
(Elsevier BV, 2016)Quantifier words like EACH, EVERY, ALL and THREE are among the most abstract words in language. Unlike nouns, verbs and adjectives, the meanings of quantifiers are not related to a referent out in the world. Rather, ... -
The logic of indirect speech
(National Academy of Sciences, 2008)When people speak, they often insinuate their intent indirectly rather than stating it as a bald proposition. Examples include sexual come-ons, veiled threats, polite requests, and concealed bribes. We propose a three-part ...
