The Extracellular Matrix of Staphylococcus aureus Biofilms Comprises Cytoplasmic Proteins That Associate with the Cell Surface in Response to Decreasing pH
(American Society of Microbiology, 2014)ABSTRACT Biofilm formation by Staphylococcus aureus involves the formation of an extracellular matrix, but the composition of this matrix has been uncertain. Here we report that the matrix is largely composed of cytoplasmic ... -
Extracellular matrix stiffness causes systematic variations in proliferation and chemosensitivity in myeloid leukemias
(National Academy of Sciences, 2016)Extracellular matrix stiffness influences biological functions of some tumors. However, it remains unclear how cancer subtypes with different oncogenic mutations respond to matrix stiffness. In addition, the relevance of ... -
Extracting All the Randomness and Reducing the Error in Trevisan's Extractors
(Elsevier, 2002)We give explicit constructions of extractors which work for a source of any min-entropy on strings of length n. These extractors can extract any constant fraction of the min-entropy using O(log<sup>2</sup><i>n</i>) additional ... -
Extracting black-hole rotational energy: The generalized Penrose process
(American Physical Society (APS), 2014)In the case involving particles the necessary and sufficient condition for the Penrose process to extract energy from a rotating black hole is absorption of particles with negative energies and angular momenta. No torque ... -
Extracting Randomness from Samplable Distributions
(IEEE Computer Society Press, 2000)The standard notion of a randomness extractor is a procedure which converts any weak source of randomness into an almost uniform distribution. The conversion necessarily uses a small amount of pure randomness, which can ... -
Extracting Sequence Features to Predict Protein–DNA Interactions: A Comparative Study
(Oxford University Press, 2008)Predicting how and where proteins, especially transcription factors (TFs), interact with DNA is an important problem in biology. We present here a systematic study of predictive modeling approaches to the TF–DNA binding ... -
Extracting the Density Profile of an Electronic Wave Function in a Quantum Dot
(American Physical Society, 2011)We use a model of a one-dimensional nanowire quantum dot to demonstrate the feasibility of a scanning probe microscope (SPM) imaging technique that can extract both the energy of an electron state and the amplitude of its ... -
Extraction and sequencing of human and Neanderthal mature enamel proteins using MALDI-TOF/TOF MS
(Elsevier BV, 2009)We report here the first results of a method to extract and sequence mature enamel proteins from modern human and Neanderthal tooth enamel. Using MALDI-TOF/TOF mass spectrometry and a combination of direct sequencing and ... -
Extraction phenomena in synchronous TAG syntax and semantics.
(Association for Computational Linguistics, 2007)We present a proposal for the structure of noun phrases in Synchronous Tree-Adjoining Grammar (STAG) syntax and semantics that permits an elegant and uniform analysis of a variety of phenomena, including quantifier scope ... -
Extragalactic Transients in the Era of Wide-Field Radio Surveys. I. Detection Rates and Light Curve Characteristics
(IOP Publishing, 2015)The impending era of wide-field radio surveys has the potential to revolutionize our understanding of astrophysical transients. Here we evaluate the prospects of a wide range of planned and hypothetical radio surveys using ... -
Extranatural Inflation
(American Physical Society, 2003)We present a new model of inflation in which the inflaton is the extra component of a gauge field in a 5D theory compactified on a circle. The chief merit of this model is that the potential comes only from nonlocal effects ... -
Extraordinary Late‐Time Infrared Emission of Type IIn Supernovae
(American Astronomical Society, 2002)Near-infrared observations are presented for five Type IIn supernovae (SN 1995N, SN 1997ab, SN 1998S, SN 1999Z, and SN 1999el) that exhibit strong infrared excesses at late times (tgreater than or similar to100 days). H- ... -
Extraordinary Sex Ratios and the Evolution of Male Neoteny in Sib-Mating Ozopemon Beetles
(Oxford University Press (OUP), 2002-03)The weevil subfamily Scolytinae includes at least seven groups of regularly sib-mating species with extremely female-biased offspring sex ratios. The enigmatic SE-Asian bark beetle genus Ozopemon (25 spp.) belong to the ... -
Extrapolating the evolution of galaxy sizes to the epoch of reionization
(Wiley-Blackwell, 2011)We use data on the high-redshift evolution of the size distribution and luminosity function of galaxies to constrain the relationship between their star formation efficiency and starburst lifetime. Based on the derived ... -
Extrapolation of Galactic Dust Emission at 100 Microns to Cosmic Microwave Background Radiation Frequencies Using FIRAS
(IOP Publishing, 1999)We present predicted full-sky maps of submillimeter and microwave emission from the diffuse interstellar dust in the Galaxy. These maps are extrapolated from the 100 μm emission and 100/240 μm flux ratio maps that Schlegel, ... -
Extrasolar planet detection by binary stellar eclipse timing: evidence for a third body around CM Draconis
(EDP Sciences, 2008-03)Aims. Our objective is to elucidate the physical process that causes the observed observed-minus-calculated (O-C) behavior in the M4.5/ M4.5 binary CM Dra and to test for any evidence of a third body around the CM Dra ... -
Extremal Limits and Black Hole Entropy
(Springer, 2009)Taking the extremal limit of a non-extremal Reissner-Nordstrom black hole (by externally varying the mass or charge), the region between the inner and outer event horizons experiences an interesting fate--while this region ... -
Extreme Brightness Temperatures and Refractive Substructure in 3C 273 with RadioAstron
(American Astronomical Society, 2016)Earth–space interferometry with RadioAstron provides the highest direct angular resolution ever achieved in astronomy at any wavelength. RadioAstron detections of the classic quasar 3C 273 on interferometric baselines up ... -
Extreme Host Galaxy Growth in Powerful Early-Epoch Radio Galaxies
(IOP Publishing, 2012)During the first half of the universe's life, a heyday of star formation must have occurred because many massive galaxies are in place after that epoch in cosmic history. Our observations with the revolutionary Herschel ...
