Competition between Surface Layering and Surface Phase Formation in Dilute Liquid Hg−Au Alloys
(American Chemical Society, 1999)We present temperature-dependent X-ray reflectivity measurements of liquid Hg alloyed with 0.06−0.20 atom % Au. At low Au concentrations, we find temperature-dependent surface-induced layering similar to that observed in ... -
Competition between triplet superconductivity and antiferromagnetism in quasi-one-dimensional electron systems
(American Physical Society (APS), 2004)We investigate the competition between antiferromagnetism and triplet superconductivity in quasi-one-dimensional electron systems. We show that the two order parameters can be unified using a SO(4) symmetry and demonstrate ... -
Competition drives cooperation among closely related sperm of deer mice
(Nature Publishing Group, 2010)Among the extraordinary adaptations driven by sperm competition is the cooperative behaviour of spermatozoa. By forming cooperative groups, sperm can increase their swimming velocity and thereby gain an advantage in intermale ... -
Competition for Attention
(National Bureau of Economic Research, 2013)We present a model of market competition and product differentiation in which consumers' attention is drawn to the products' most salient attributes. Firms compete for consumer attention via their choices of quality and ... -
Competition, Financial Discipline and Growth
(Oxford University Press (OUP), 1999)This paper develops a general equilibrium model of technological adoption in an economy populated by 'satisficing' entrepreneurs whose main objective is to minimise innovative effort while keeping the firm alive. In such ... -
Competition, Imitation and Growth with Step-by-Step Innovation
(Oxford University Press (OUP), 2001)Is more intense product market competition and imitation good or bad for growth? This question is addressed in the context of an endogenous growth model with “step-by-step” innovations, in which technological laggards must ... -
Competition-Colonization Dynamics in an RNA Virus
(National Academy of Sciences, 2010)During replication, RNA viruses rapidly generate diverse mutant progeny which differ in their ability to kill host cells. We report that the progeny of a single RNA viral genome diversified during hundreds of passages in ... -
Compiling Polymorphism Using Intensional Type Analysis
(Association for Computing Machinery, 1995)Traditional techniques for implementing polymorphism use a universal representation for objects of unknown type. Often, this forces a compiler to use universal representations even if the types of objects are known. We ... -
Complementarities between Outsourcing and Foreign Sourcing
(American Economic Association, 2005) -
Complementarity and stability conditions
(Elsevier BV, 2017)We discuss the issue of complementarity between the confining phase and the Higgs phase for gauge theories in which there are no light particles below the scale of confinement or spontaneous symmetry breaking. We show with ... -
Complementary Rather than Contradictory: Diversity and Excellence in Peer Review and Admissions in American Higher Education
(Taylor & Francis, 2009)Diversity is largely accepted as a positive value in American society. Nevertheless, policies to encourage diversity, e.g. affirmative action, language policies and legalising illegal immigrants, are still largely disputed, ... -
Complementary strand relocation may play vital roles in RecA-based homology recognition
(Oxford University Press, 2012)RecA-family proteins mediate homologous recombination and recombinational DNA repair through homology search and strand exchange. Initially, the protein forms a filament with the incoming single-stranded DNA (ssDNA) bound ... -
Complementary targeting of liposomes to IL-1? and TNF-? activated endothelial cells via the transient expression of VCAM1 and E-selectin
(Elsevier BV, 2011)Inflammation is in part defined by the transient upregulation of cell adhesion molecules on the surface of endothelial cells (ECs) in response to cytokines. We hypothesized that liposomes with a complementary surface ... -
A Complete Generic Phylogeny of Malpighiaceae Inferred from Nucleotide Sequence Data and Morphology
(Botanical Society of America, 2010)Premise of the study: The Malpighiaceae include ∼1300 tropical flowering plant species in which generic definitions and intergeneric relationships have long been problematic. The goals of our study were to resolve relationships ... -
The complete genome sequence of a Neandertal from the Altai Mountains
(2014)We present a high-quality genome sequence of a Neandertal woman from Siberia. We show that her parents were related at the level of half siblings and that mating among close relatives was common among her recent ancestors. ... -
The Complete Genome Sequence of Proteus mirabilis Strain BB2000 Reveals Differences from the P. mirabilis Reference Strain
(American Society for Microbiology, 2013)We announce the complete genome sequence for Proteus mirabilis strain BB2000, a model system for self recognition. This opportunistic pathogen contains a single, circular chromosome (3,846,754 bp). Comparisons between this ... -
Complete Genome Sequence of Pseudomonas aeruginosa Phage AAT-1
(American Society for Microbiology, 2016)Aspects of the interaction between phages and animals are of interest and importance for medical applications. Here, we report the genome sequence of the lytic Pseudomonas phage AAT-1, isolated from mammalian serum. AAT-1 ... -
A Complete Medical Education Includes the Arts and Humanities

A Complete Multiwavelength Characterization of Faint Chandra X-Ray Sources Seen in the Spitzer Wide-Area Infrared Extragalactic (SWIRE) Survey
(IOP Publishing, 2005)We exploit deep combined observations with Spitzer and Chandra of the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE) in the ELAIS N1 region to investigate the nature of the faint X-ray and IR sources in common, ... -
A Complete Problem for Statistical Zero Knowledge
(Association for Computing Machinery, 2003)We present the first complete problem for SZK, the class of (promise) problems possessing statistical zero-knowledge proofs (against an honest verifier). The problem, called STATISTICAL DIFFERENCE, is to decide whether two ...
