DeTar, Carleton | Critical behavior in Nt=4 staggered fermion thermodynamics | Quantum chromodynamics with two zero mass flavors is expected to exhibit a phase transition with O(4) critical behavior. Fixing the universality class is important for phenomenology and for facilitating the extrapolation of simulation data to physical quark mass values. Other groups have reported r... | Staggered fermions; Phase transitions | 2000-01 |

Golden, Kenneth M. | Critical behavior of transport in lattice and continuum percolation models | It has been observed that the critical exponents of transport in the continuum, such as in the Swiss cheese and random checkerboard models, can exhibit nonuniversal behavior, with values different than the lattice case. Nevertheless, it is shown here that the transport exponents for both lattice a... | Ising model; Magnetization; Scaling | 1997 |

Golden, Kenneth M. | Critical behavior of transport in percolation-controlled smart composites | The electrical transport properties of many smart composites and other technologically important materials are dominated by the connectedness, or percolation properties of a particular component. Predicting the critical behavior of such media near their percolation threshold, where one typically obt... | Matrix-particle composites | 1997 |

Mattis, Daniel C. | Critical curves and thermodynamic phases of lattice fluids and antiferromagnets with structured interactions | We study the classical lattice gas with hard cores, nearest-neighbor repulsive forces, and next-nearest-neighbor attractive forces. We find several thermodynamic phases (vapor, liquid, and solid) and unusually shaped critical curves, yet no critical point or triple point. We find and discuss discont... | Ising antiferromagnet; Molecular field theory | 1971-06 |

Capecchi, Mario R. | Critical role of tissue angiotensin-converting enzyme as revealed by gene targeting in mice | Angiotensin-converting enzyme (ACE) generates the vasoconstrictor angiotensin II, which plays a critical role in maintenance of blood pressure in mammals. Although significant ACE activity is found in plasma, the majority of the enzyme is bound to tissues such as the vascular endothelium. We used ta... | Blood pressure; ACE activity; Enzyme | 1997-03-06 |

Bohs, Lynn A. | Crossing studies in Cyphomandra (Solanaceae) and their systematic and evolutionary significance | A crossing program involving eight species of Cyphomandra was instituted to elucidate systematic relationships between the taxa and evolutionary mechanisms operating in the genus. The results show that gametophytic self-incompatibility is widespread in Cyphomandra. Pollen tubes were able to reach ... | Solanum maternum; Crossing studies | 1991 |

Beckerle, Mary C. | CRP1, a LIM domain protein implicated in muscle differentiation, interacts with α-actinin | Members of the cysteine-rich protein (CRP) family are LIM domain proteins that have been implicated in muscle differentiation. One strategy for defining the mechanism by which CRPs potentiate myogenesis is to characterize the repertoire of CRP binding partners. | CRP1; Cysteine-rich proteins; Actinin; Protein-protein interactions; LIM domains | 1997 |

Miller, Joel Steven | Crystal engineering or crystal mysticism? A case study | The de novo design and synthesis of a crystalline motif of a substance is a holy grail for a growing number of organic and inorganic synthetic chemists. Achievement of targeted architectural arrangements is less reliable as the complexity increases. Simple substitution of, for example, alkyl penda... | Synthesis, Structure, Chemistry | 2005 |

Gesteland, Raymond F.; Krapcho, Karen J.; Talbot, Phil; Thulin, Craig | Crystallization of the MS2 translational repressor alone and complexed to bromouridine | The coat protein from the MS2 bacteriophage plays a dual role by encapsidating viral RNA and also by binding RNA as a translational repressor. In order to study the isolated dimer in a conformation not influenced by capsid interactions, a mutant molecule was crystallized that is defective in capsid ... | Crystallization; RNA Bacteriophage; RNA Hairpin; Translational Repressor | 1995 |

Vardeny, Zeev Valentine | Cylindrical micolasers and light emitting devices from conducting polymers | Substantially improved, photopumped polymer lasers are demonstrated using microrings and microdisks of various diameters D ranging from 5 to 200 mm. Various cavity-dependent laser modes were observed, which for D,10 mm were dominated by a single longitudinal mode with linewidth of less than 1 Å.

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 America | 1994 |

Beckerle, Mary C. | Cysteine-rich protein family of highly related LIM domain proteins | Here 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 proteins | 1995 |

Beckerle, Mary C. | Cytoskeleton-associated PDZ-LIM protein, ALP, acts on serum response factor activity to regulate muscle differentiation | In 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 architecture | 2007 |

Gondolo, Paolo | Daily modulation due to channeling in direct dark matter crystalline detectors | The 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 |

Gondolo, Paolo | Dark matter and relic particles | For 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.

Gondolo, Paolo | Dark matter and the first stars: a new phase of stellar evolution | A 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 stars | 2008-02 |

Gondolo, Paolo | Dark matter annihilation at the galactic center | Cold 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 flux | 1999-08 |

Gondolo, Paolo | Dark matter axions revisited | We 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 angle | 2009-08 |

Gondolo, Paolo | Dark matter in the MSSM golden region | Dark 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 mass | 2009-02 |
