Convection from a Source in an Ocean Basin
(Elsevier, 1990)A model is presented for the deep interior stratification and upwelling in an ocean basin connected to a marginal sea. Three elements make up the model: a marginal sea, a turbulent boundary current and an interior region. ... -
Convective injection and photochemical decay of peroxides in the tropical upper troposphere: Methyl iodide as a tracer of marine convection
(Wiley-Blackwell, 1999)The convective injection and subsequent fate of the peroxides H2O2 and CH3OOH in the upper troposphere is investigated using aircraft observations from the NASA Pacific Exploratory Mission-Tropics A (PEM-Tropics A) over ... -
Convective outflow of South Asian pollution: A global CTM simulation compared with EOS MLS observations
(Wiley-Blackwell, 2005)A global 3-D chemical transport model is used to analyze observations of carbon monoxide (CO) and upper tropospheric clouds from the EOS Microwave Limb Sounder (MLS). MLS observations during 25 August–6 September 2004 ... -
Convective transport over the central United States and its role in regional CO and ozone budgets
(Wiley-Blackwell, 1994)We have constructed a regional budget for boundary layer carbon monoxide over the central United States (32.5°–50°N, 90°–105°W), emphasizing a detailed evaluation of deep convective vertical fluxes appropriate for the month ... -
Convergence
(University of Chicago Press, 1992)A key economic issue is whether poor countries or regions tend to grow faster than rich ones: are there automatic forces that lead to convergence over time in the levels of per capita income and product? We use the ... -
Convergence in Multispecies Interactions
(Elsevier BV, 2016)The concepts of convergent evolution and community convergence highlight how selective pressures can shape unrelated organisms or communities in similar ways. We propose a related concept, convergent interactions, to ... -
Convergence in pigmentation at multiple levels: mutations, genes and function
(The Royal Society, 2010)Convergence—the independent evolution of the same trait by two or more taxa—has long been of interest to evolutionary biologists, but only recently has the molecular basis of phenotypic convergence been identified. Here, ... -
Convergence or Collision? Archival Appraisal and the Expanded Role of Special Collections in the Research Library
(2016)The deadpan comedian Steven Wright has a joke I have always been fond of. “You can’t have everything. Where would you put it?” My role today is to give perspective from special collections and archives within the research ... -
Convergence to equilibrium of conservative particle systems on ℤ\bmd
(Institute of Mathematical Statistics, 2003)We consider the Ginzburg--Landau process on the lattice ℤdZd whose potential is a bounded perturbation of the Gaussian potential. We prove that the decay rate to equilibrium in the variance sense is t−d/2t−d/2 up to ... -
Convergence, Adaptation, and Constraint
(Wiley, 2011)Convergent evolution of similar phenotypic features in similar environmental contexts has long been taken as evidence of adaptation. Nonetheless, recent conceptual and empirical developments in many fields have led to a ... -
Convergences and Divergences Between God and Hero in the Mnesiepes Inscription of Paros
(Archaeological Institute of Paros and Cyclades, 2008)In his pathfinding book, Archilochos Heros, Diskin Clay has questioned the applicability of a well-known formula for distinguishing between the cult of heroes and the cult of gods in archaic, classical, and postclassical ... -
Convergent Evolution of Novel Protein Function in Shrew and Lizard Venom
(Elsevier BV, 2009)How do proteins evolve novel functions? To address this question, we are studying the evolution of a mammalian toxin, the serine protease BLTX [1], from the salivary glands of the North American shrew Blarina brevicauda. ... -
Convergent evolution of phenotypic integration and its alignment with morphological diversification in Caribbean Anolis ecomorphs
(Wiley-Blackwell, 2011)The adaptive landscape and the G-matrix are keys concepts for understanding how quantitative characters evolve during adaptive radiation. In particular, whether the adaptive landscape can drive convergence of phenotypic ... -
Convergent Evolution of Sexual Dimorphism in Skull Shape Using Distinct Developmental Strategies
(Wiley-Blackwell, 2013)Studies integrating evolutionary and developmental analyses of morphological variation are of growing interest to biologists as they promise to shed fresh light on the mechanisms of morphological diversification. Sexually ... -
Convergent evolutionary reduction of atrial septation in lungless salamanders
(Wiley-Blackwell, 2016)Nearly two thirds of the approximately 700 species of living salamanders are lungless. These species respire entirely through the skin and buccopharyngeal mucosa. Lung loss dramatically impacts the configuration of the ... -
Convergent Excitatory Pathways Mediate the Zebrafish Escape Behavior
(2015-05-14)Scientists have long been fascinated by how anatomical structures in the brain can generate the diversity of behaviors apparent in the animal kingdom. While the ultimate goal of neuroscience is to understand complex brain ... -
Convergent Interactions Among Pitcher Plant Microcosms in North America and Southeast Asia
(2016-08-03)Ecosystems are composed of diverse suites of organisms whose interactions are mediated by both the biotic and abiotic constraints of their environments. The complexity of ecosystems makes them both resilient and difficult ... -
Convergent regulatory evolution and loss of flight in paleognathous birds
(American Association for the Advancement of Science (AAAS), 2019-04-04)A core question in evolutionary biology is whether convergent phenotypic evolution is driven by convergent molecular changes in proteins or regulatory regions. We combined phylogenomic, developmental, and epigenomic analysis ... -
Converging in Crisis: The International Impact of Europe’s Energy Crisis on Natural Gas Prices
(2023-06-30)In the span of seven years, the United States has switched from being a net importer of LNG to the largest LNG exporter in the world. This is a historic shift in energy markets that has received little attention in the ... -
A Conversation with Herman Chernoff
(Institute of Mathematical Statistics, 1996)Herman Chernoff was born in New York City on 1 July 1923. He went to school there and later received the B.S. degree from the City College of New York in 1943, majoring in mathematics with a minor in physics. For a year ...
