Breaking the Symmetry Between Interaction and Replacement in Evolutionary Dynamics on Graphs
(American Physical Society, 2007)We study the evolution of cooperation modeled as symmetric 2×2 games in a population whose structure is split into an interaction graph defining who plays with whom and a replacement graph specifying evolutionary competition. ... -
Breaking the Vacuum: Ricardian and Henrician Ovidianism
(Duke University Press, 1999) -
Breaking trade-offs between translucency and diffusion in particle-doped films
(Optical Society of America (OSA), 2014)Particle-doped thin films that are translucent and diffusive have applications in cosmetics, coatings, and display technologies, but finding material combinations that produce these effects simultaneously is challenging: ... -
Breathing Room for Early Animals
(Nature Publishing Group, 1996)Did an increase in atmospheric oxygen concentration some time during the Neoproterozoic era, 1,000 to 543 million years ago, make possible the diversification of multicellular animals? -
Breed Differences in Domestic Dogs' (Canis familiaris) Comprehension of Human Communicative Signals
(John Benjamins Publishing Company, 2009)Recent research suggests that some human-like social skills evolved in dogs (Canis familiaris) during domestication as an incidental by-product of selection for “tame” forms of behavior. It is still possible, however, that ... -
Bridging cultural sociology and cognitive psychology in three contemporary research programmes
(Springer Nature, 2017)Three prominent research programs in cognitive psychology would benefit from a stronger engagement with the cultural context of cognition: studies of poverty focused on scarcity and cognitive bandwidth (CB); of the ... -
Bridging length scales to measure polymer assembly
(American Society for Cell Biology, 2017)Time-resolvable quantitative measurements of polymer concentration are very useful to elucidate protein polymerization pathways. There are numerous techniques to measure polymer concentrations in purified protein solutions, ... -
Brief communication: Contributions of enamel-dentine junction shape and enamel deposition to primate molar crown complexity
(Wiley-Blackwell, 2010)Molar crown morphology varies among primates from relatively simple in some taxa to more complex in others, with such variability having both functional and taxonomic significance. In addition to the primary cusps, crown ... -
Brief communication: Dental development and enamel thickness in the Lakonis Neanderthal molar
(Wiley-Blackwell, 2009)Developmental and structural affinities between modern human and Neanderthal dental remains continue to be a subject of debate as well as their utility for informing assessments of life history and taxonomy. Excavation of ... -
Brief communication: Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts
(Copernicus GmbH, 2018-07-27)Stratospheric aerosol geoengineering, a form of solar geoengineering, is a proposal to add a reflective layer of aerosol to the stratosphere to reduce net radiative forcing and so to reduce the risks of climate change. The ... -
A Brief History of Education in the United States
(American Economic Association, 1999)This essay is the companion piece to about 550 individual data series on education to be included in the updated Historical Statistics of the United States, Millennial Edition (Cambridge University Press 2000, forthcoming). ... -
A Brief History of Generative Models for Power Law and Lognormal Distributions
(2001)Power law distributions are an increasingly common model for computer science applications; for example, they have been used to describe file size distributions and in- and out-degree distributions for the Web and Internet ... -
Brief Report: VGLL4 Is a Novel Regulator of Survival in Human Embryonic Stem Cells
(AlphaMed Press, 2013)Human embryonic stem cells (hESCs) are maintained in a self-renewing state by an interconnected network of mechanisms that sustain pluripotency, promote proliferation and survival, and prevent differentiation. We sought ... -
Bright and Fast Multicoloured Voltage Reporters via Electrochromic FRET
(Nature Publishing Group, 2014)Genetically encoded fluorescent reporters of membrane potential promise to reveal aspects of neural function not detectable by other means. We present a palette of multicoloured brightly fluorescent genetically encoded ... -
Bright and stable luminescent probes for target engagement profiling in live cells

Bright, guided molecular beam with hydrodynamic enhancement
(AIP Publishing, 2007)The authors realize a novel high flux source of cold atoms and molecules employing hydrodynamic enhancement of an effusive aperture at cryogenic temperatures. Molecular oxygen from the source is coupled to a magnetic guide, ... -
Brightening of an Accretion Disk due to Viscous Dissipation of Gravitational Waves during the Coalescence of Supermassive Black Holes
(American Physical Society, 2008-07-25)Mergers of supermassive black hole binaries release peak power of up to similar to 10(57)erg s(-1) in gravitational waves (GWs). As the GWs propagate through ambient gas, they induce shear and a small fraction of their ... -
Brillouin Light Scattering Measurement of the Elastic Properties of Aligned Multilamella Lipid Samples
(National Academy of Sciences, 1978)Brillouin measurements of the elastic properties are presented for aligned multilamella samples of both pure dipalmitoyl phosphatidylcholine at various temperatures and water concentrations and for the same compound ... -
Brillouin Scattering from Smectic Liquid Crystals
(American Physical Society, 1973)Brillouin-scattering results are reported for monodomain samples of \(\beta\)-methyl butyl p [(p-methoxy benzylidine)amino] cinnamate in both the smectic-A and -B phases. For both phases theoretical predictions are confirmed ...
