Mattis, Daniel C. | Few-body problem on a lattice | The author explores some of the inherent simplifications of "quantum lattice physics." He distinguishes between fermions and bosons and analyzes the n-body problem for each, with n = 1,2,3... typically a small number. With delta-function (zero-range) interactions, the three-body problem on a lattice... | Quantum; Electrons; Spin | 1986 |

Morse, Michael David | Spectroscopic analysis of jet-cooled AICu | Diatomic AlCu has been interrogated using resonant two-photon ionization spectroscopy in a supersonic expansion of helium. The ground state is shown to be X l?+, deriving from the 3&3dgd configuration, in agreement with theoretical predictions. The closed-shell nature of this molecule results in a l... | 1993 | |

Hughes, Kelly T. | Flagellar anti-σ factor FlgM actively dissociates Salmonella typhimurium σ28 RNA polymerase holoenzyme | The anti-σ factor FlgM of Salmonella typhimurium inhibits transcription of class 3 flagellar genes through a direct interaction with the flagellar-specific σ factor, σ28. FlgM is believed to prevent RNA polymerase (RNAP) holoenzyme formation by sequestering free σ28. We have analyzed FlgM-media... | sigma-factors; transcription; FlgM; Flagellum | 1998 |

Jorgensen, Erik | μ2 adaptin facilitates but is not essential for synaptic vesicle recycling in Caenorhabditis elegans | Synaptic vesicles must be recycled to sustain neurotransmission, in large part via clathrin-mediated endocytosis. Clathrin is recruited to endocytic sites on the plasma membrane by the AP2 adaptor complex. The medium subunit (u 2) of AP2 binds to cargo proteins and phosphatidylinositol-4,5-bisph... | Synaptic vesicles; Caenorhabditis elegans; Adaptin | 2008 |

Zick, Cathleen D. | Over-scheduled or at loose ends? The shifting balance of adolescent time use | Little is known about the time use of American youth. In this study, time diary data from 1977-78 and 2003-05 are used to investigate time use in middle adolescence with the goals of ascertaining (1) changes in time use, (2) how socioeconomic and familial factors influence adolescent time allocation... | Adolescents; Adolescent time use; Adolescent wages; Leisure | 2007-05-18 |

Gopalakrishnan, Ganesh | Specification-driven design of custom hardware in HOP | We present a language "Hardware viewed as Objects and Processes" (HOP) for specifying the structure, behavior, and timing of hardware systems. HOP embodies a simple process model for lock-step synchronous processes. Processes may be described both as a black-box and as a collection of interacting s... | HOP; hardware systems; Structure; Behavior; Timing; custom hardware | 1988 |

Coley, Phyllis D. | Uprooting and snapping of trees: structural determinants and ecological consequences | The influence of mechanical and architectural properties of trees on growth rates, mortality rates, and relative probabilities of snapping and uprooting were examined on Barro Colorado Island, Republic of Panama. Of 310 fallen trees, 70% snapped, 25% uprooted, and 5% broke off at ground level. Stepw... | Snapping; Uprooting | 1983 |

Smith, Ken R.; Bean, Lee Lawrence; Mineau, Geraldine Page; Fraser, Alison M.; Lane, Diana | Infant deaths in Utah, 1850-1939 | Of all the health revolutions that have taken place in the United States since 1850, the reduction of infant mortality is arguably the most dramatic and far-reaching. Because of the incompleteness and unreliability of surviving vital records,, we will probably never know precisely the rate of infan... | Death; Utah; Infant mortality | 2002 |

Vardeny, Zeev Valentine | Universal properties of quasi-one-dimensional excitons in semiconducting single-walled carbon nanotubes and ∏-conjugated polymers | The nature of the primary photoexcitations in semiconducting single-walled carbon nanotubes (S-SWCNTs) is of strong current interest. We have studied the emission spectra of S-SWCNTs and two different rr-conjugated polymers in solutions and films, and have also performed ultrafast pump-probe spectr... | Carbon nanotubes; pi-conjugated polymers; SWCNT; Photoexcitation; Optoelectronic properties; Quasi-one-dimensional | 2006 |

Rajamani, Raj | Advances in discrete element method application to grinding mills | Discrete element method (DEM) has made significant impact in the design and operation of grinding mills. The internal charge motion of grinding balls and ore can be readily examined. As a result, this method enables one to design and examine mill internals via simulation. This manuscript details es... | 2014-01-01 | |

Mattis, Daniel C. | Theory of magnetothermomechanics | We show that in both ferromagnetic and antiferromagnetic systems with weak magnetostrictive coupling the coefficient of thermal expansion gives a useful measure of the magnetic specific heat. We also analyze the strong coupling situation by means of our simplified, but soluble model, and find it pos... | Magnetothermomechanics; Magnetostriction | 1963-01 |

Bromley, Benjamin C. | Periodic standing-wave approximation: nonlinear scalar fields, adapted corrdinates, and the eigenspectral method | The periodic standing wave (PSW) method for the binary inspiral of black holes and neutron stars computes exact numerical solutions for periodic standing-wave spacetimes and then extracts approximate solutions of the physical problem, with outgoing waves. The method requires solution of a boundary-... | Periodic standing wave method; Black holes; Neutron stars | 2005 |

Yu, Zhou | Misleading comparisons of homeownership rates when the variable effect of household formation is ignored: explaining rising homeownership and the homeownership gap between Blacks and Asians | Despite ominous signs of housing market stress in the U.S., the homeownership rate reached an all time high in 2006. The conventional definition of homeownership, which is based on the share of households and ignores the effects of variable household formation, confounds the measurement of "success"... | 2010-01-01 | |
