1601 Bohs, Lynn A.Cyphomandra (Solanaceae)Unusual ecological aspects of Cyphomandra include its pollination syndrome and herbivore relationships. Male euglossine bees may be important pollinators of Cyphomandra flowers, and the primary attractants may not be pollen, but odor substances secreted by the anther connectives. Specialized herbi...Cyphomandra; Latin America1994
1602 Beckerle, Mary C.Cysteine-rich protein family of highly related LIM domain proteinsHere we describe a family of closely related LIM domain proteins in avian cells. The LIM motif defines a zinc-binding domain that is found in a variety of transcriptional regulators, proto-oncogene products, and proteins associated with sites of cell-substratum contact. One type of LIM-domain protei...LIM domains; Chicken embryo fibroblasts; Quail embryo fibroblasts; Cell growth; Cell development; Cysteine-rich proteins1995
1603 Thomas, Kirk R.Cytochrome P450 2B diversity and dietary novelty in the herbivorous, desert woodrat (Neotoma lepida)Detoxification enzymes play a key role in plant-herbivore interactions, contributing to the on-going evolution of ecosystem functional diversity. Mammalian detoxification systems have been well studied by the medical and pharmacological industries to understand human drug metabolism; however, little...2012-01-01
1604 Beckerle, Mary C.Cytoskeleton-associated PDZ-LIM protein, ALP, acts on serum response factor activity to regulate muscle differentiationIn this report, an antisense RNA strategy has allowed us to show that disruption of ALP expression affects the expression of the muscle transcription factors myogenin and MyoD, resulting in the inhibition of muscle differentiation. Introduction of a MyoD expression construct into ALP-antisense cells...Skeletal muscle; PDZ-LIM protein; Actin; Actinin-associated LIM proteins; Serum response factor; Cytoskeletal architecture2007
1605 Jalili, ThunderCytosolic, but not mitochondrial, oxidative stress likely contributes to cardiac hypertrophy resulting from cardiac specific GLUT4 deletion in miceWe hypothesized that oxidative stress may contribute to the development of hypertrophy observed in mice with cardiac specific ablation of the insulin sensitive glucose transporter gene (GLUT4, G4H-/-4 ). Measurements of oxidized glutathione (GSSG) in isolated mitochondria and whole heart homogenates...2012-01-01
1606 Seror, Denis D.D.C.P.L. - A distributed control programming languageIn this thesis, a computation is considered a system of asynchronously cooperating "independent" programs (coroutines) linked by paths of in formation along which messages are sent. A programming language called DCPL, a Distributed Control Programming Language, in which such computations may be ex...Distributed control programming language; DCPL1970
1607 Berzins, MartinDAG-based software frameworks for PDEsThe task-based approach to software and parallelism is well-known and has been proposed as a potential candidate, named the silver model, for exas-cale software. This approach is not yet widely used in the large-scale multi-core parallel computing of complex systems of partial differential equations...2012-01-01
1608 Gondolo, PaoloDaily modulation due to channeling in direct dark matter crystalline detectorsThe channeling of the ion recoiling after a collision with a weakly interacting massive particle (WIMP) in direct dark matter crystalline detectors produces a larger scintillation or ionization signal than otherwise expected. Channeling is a directional effect, which depends on the velocity distrib...2011
1609 Edelman, Linda S.Dangerous spaces: Using geographic information systems in injury researchPURPOSE: To provide an overview of geographic information systems (GIS) and to discuss current and future applications in injury and trauma research. DESIGN: Literature review and discourse of GIS technology related to injury and trauma research. METHOD: A search of scientific literature databases, ...Community; Public Health; Technology; Internet; Risk Assessment; Wounds and Injuries2007-08
1610 Chuaqui, Miguel BasimDanza del OcasoDanza del Ocaso (Dusk Dance) is a dance for three instruments, which evolves from a simple catchy humming tune shared by the three, in a Latin American inspired dancing 7/8 meter, to a complex contrapuntal texture, in a more abstract atonal language. Running throughout is the notion of transformati...Dusk Dance; Latin American; Three instruments1998

1612 Gondolo, PaoloDark matter and relic particlesFor the first time, we have a believable inventory of the contents of the universe. First, we have compelling evidence that the universe is flat (or at least very nearly so), consistent with the prediction of inflation. Measurements of the first acoustic peak in the angular power spectrum of the Cos...Relic particles; MACHOs; WIMP; Weakly interacting massive particles2001
1613 Gondolo, PaoloDark matter and the first stars: a new phase of stellar evolutionA mechanism is identified whereby dark matter (DM) in protostellar halos dramatically alters the current theoretical framework for the formation of the first stars. Heat from neutralino DM annihilation is shown to overwhelm any cooling mechanism, consequently impeding the star formation process and ...Dark stars2008-02
1614 Gondolo, PaoloDark matter annihilation at the galactic centerCold dark matter near the galactic center is accreted by the central black hole into a dense spike. Particle dark matter annihilation makes the spike a compact source of photons, electrons, positrons, protons, antiprotons, and neutrinos. The spike luminosity depends on the halo density profile: halo...Neutralinos; Neutrino flux1999-08
1615 Gondolo, PaoloDark matter axions revisitedWe study for what specific values of the theoretical parameters the axion can form the totality of cold dark matter. We examine the allowed axion parameter region in the light of recent data collected by the WMAP5 mission plus baryon acoustic oscillations and supernovae, and assume an inflationary...WMAP5 mission; PQ symmetry; Anharmonicity; Misalignment angle2009-08
1616 Gondolo, PaoloDark matter in the MSSM golden regionDark matter is examined within the ‘‘golden region'' of the minimal supersymmetric standard model. This region satisfies experimental constraints, including a lower bound on the Higgs mass of 114 GeV, and minimizes fine-tuning of the Z boson mass. Here we impose additional constraints (particula...MSSM golden region; Neutralinos; Higgs mass2009-02

1620 Gondolo, PaoloDark Stars: the first stars in the universe may be powered by dark matter healingA new line of research on Dark Stars is reviewed, which suggests that the first stars to exist in the universe were powered by dark matter heating rather than by fusion. Weakly Interacting Massive Particles, which may be there own antipartmers, collect inside the first stars and annihilate to produc...Dark stars; WIMP; Weakly interacting massive particles2009
1621 Clayton, Dale H.Darwins finches combat introduced nest parasites with fumigated cottonIntroduced parasites are a threat to biodiversity when naïve hosts lack effective defenses against such parasites [1]. Several parasites have recently colonized the Galápagos Islands, threatening native bird populations [2]. For example, the introduced parasitic nest fly Philornis downsi (Diptera:...2014-01-01

1623 Berzins, MartinData and range-bounded polynomials in ENO methodsEssentially Non-Oscillatory (ENO) methods and Weighted Essentially Non- Oscillatory (WENO) methods are of fundamental importance in the numerical solution of hyperbolic equations. A key property of such equations is that the solution must remain positive or lie between bounds. A modification of the ...2012-01-01
1624 Jameson, Kenneth P.Data and social science rhetoric: policy and instructionI believe that social science and empirical investigation can make important contributions to our understanding and to resolution of policy issues, but only if we are clear on the nature of social science and the role of quantification. In particular we must admit the limits of our truth claims, th...Social sciences; Quantification; Empirical investigation1996
