Fogel, Alan Dale | Maternal speech to three-month-old infants in the United States and Japan | An American-Japanese comparison of maternal speech to 3-month-old infants is presented. Mother-infant dyads were videotaped in the laboratory, and the maternal speech was analysed by function and syntactic form. US mothers were more information-oriented than were Japanese mothers; they also used mor... | Maternal speech; Information-oriented; Affect-oriented; Prelinguistic infants; Baby talk | 1990 |

Bohs, Lynn A. | Solanum allophyllum (Miers) Standl. and the generic delimitation of Cyphomandra and Solanum (Solanaceae) | Solanum allophyllum has previously been placed in Cyphomandra and in Solarium. This species has a number of morphological features not found in Cyphomandra, but has been included in the genus because it has a similar growth habit, three-leaved sympodial units with inflorescences in branch forks, and... | Solanum allophyllum; Cyphomandra | 1989 |

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.

Vardeny, Zeev Valentine | Photoinduced infrared activity in polyacetylene | Photoexcitation of trans - but not cis -polyacetylene, results in the appearance of strongly-ir-active local modes at 1370 and 1260 cm-1. This observation demonstrates that the photogeneration of self-localized charge carriers is unique to the trans isomer. In spite of their localization the kineti... | Photoinduced infrared activity; Photoexcitation | 1983-06 |

Mishchenko, Eugene | Thermal conductivity of a two-dimensional electron gas with Coulomb interaction | We demonstrate that forward electron-electron scattering due to Coulomb interaction in a two-dimensional ballistic electron-gas leads to the (T ln T)21 temperature dependence of the thermal conductivity, which is logarithmically suppressed compared to the usual Fermi-liquid behavior. | Coulomb drag; Coulomb interaction | 2003-01 |

Miller, Joel Steven | Collinear ferromagnetism and spin orientation in the molecule-based magnets M[N(CN)2]2 (M=Co,Ni) | Zero-field unpolarized neutron powder diffraction has been used to study the low-T magnetic structure and T-dependent crystal structure of M[N(CN)2]2 (M=Co,Ni). Both compounds show collinear ferromagnetism with spin orientation along the c axis. The results provide the determination of a complete ma... | Magnetic; Diffraction; Structure | 1999 |

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 |

Chapman, David S.; Harris, Robert N.; Allis, Richard George | Gravity signals at the Geysers geothermal system | Three high-precision gravity and GPS surveys have been conducted over The Geysers geothermal reservoir and surrounding area. These surveys, in September 2000, April 2001, and September 2001, provide an initial baseline for future imaging studies of spatial mass changes from the Santa Rosa Efflu... | Ground water change; Gravity surveys | 2002 |

Sample, Susan | Shattering stereotypes: aging adults aren't naturally unhappy | Healthy older adults ramain engaged and interested in life. Just because they're aging doesn't mean they lose interest in life. "In this culture, we have a perception of what it's like to grow old: life isn't a whole lot of fun" We have an image of older adults whose faces are lined with fatigue as ... | Aging Adults; Depression; Geriatrics | 1998-12 |

Mathews, V. John | Subband vector quantization of images using hexagonal filter banks | Abstract Results of psychophysical experiments on human vision conducted in the last three decades indicate that the eye performs a multichannel decomposition of the incident images. This paper presents a subband vector quantization algorithm that employs hexagonal filter banks. The hexagonal filte... | 1992 | |

Zimmer, Zachary | Impact of past conflicts and social disruption on the elderly in Cambodia | Cambodia experienced violence during the rule of the Khmer Rouge in the 1970s. Many who died were the children or spouses of today's elderly. This may have resulted in an erosion of family support in a country where formal channels of assistance are virtually absent. This article examines the extent... | Cambodia; Elderly; Social Disruption; Conflicts; Poverty | 2006-06 |

Downes, Stephen M. | Heredity and heritability | Philosophical discussions of heredity have focused on the sustainability of heritability analyses and more recently on the units of heredity. Here I introduce the concept of heritability and the problems associated with it. Next the units of heredity discussion is introduced.

Blair, David F. | MotA protein of E. coli is a proton-conducting component of the flagellar motor | A number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered... | MotA protein; MotA gene; Flagellar motor; Proton-conducting | 1990 |

Mishchenko, Eugene | Coulomb drag by small momentum transfer between quantum wires | We demonstrate that in a wide range of temperatures Coulomb drag between two weakly coupled quantum wires is dominated by processes with a small interwire momentum transfer. Such processes, not accounted for in the conventional Luttinger liquid theory, cause drag only because the electron dispersion... | Coulomb drag; Quantum wires; Luttinger liquid | 2003-09 |

Liu, Feng | Creation of "quantum platelets" via strain-controlled self-organization at steps | We demonstrate, by both theory and experiment, the strain-induced self-organized formation of "quantum platelets," monolayer-thick islands of finite dimensions. They form at the early stage of heteroepitaxial growth on a substrate with regularly spaced steps, and align along the steps. In the direc... | Quantum platelets; Strain-controlled self-organization; Monolayer-thick islands; Heteroepitaxial growth | 2000-12 |

Vardeny, Zeev Valentine | Excitons in poly(para-phenylenevinylene) | We show that one-electron band theory fails to describe optical absorption in PPV and the absorption spectrum can be described only within a Coulomb-correlated model. The lowest optical state is an exciton, whose binding energy is estimated theoretically to be 0.90 ± 0 . 1 5 e V Measurements of the... | Poly(para-phenylenevinylene); PPV | 1994-11 |
