Smith, Ken R. | Allied health manpower strategies: estimates of the potential gains from efficient task delegation | This study analyzes the potential impact of physician extenders on the productivity of primary care practices and considers the consequent implication for future health manpower requirements. A number of previous investigations have evaluated a variety of extenders in experimental settings. This stu... | | 1973 |

Wolfinger, Nicholas H. | Alone in the ivory tower: how birth events vary among male and female fast-track professionals | We use data from the 2000 Census Public Use Microsample to examine the likelihood of a birth event, defined as the household presence of a child under two years old, for male and female professionals. Physicians have the highest rate of birth events, followed in order by attorneys and academics. W... | Fertility; Family; Occupation; Academic careers; Census | 2009-06-10 |

Beckerle, Mary C. | ALP-enigma protein ALP-1 functions in actin filament organization to promote muscle structural integrity in Caenorhabditis elegans | Mutations that affect the Z-disk-associated ALP-Enigma proteins have been linked to human muscular and cardiac diseases. Despite their clear physiological significance for human health, the mechanism of action of ALP-Enigma proteins is largely unknown. In Caenorhabditis elegans, the ALP-Enigma prot... | Actin; Caenorhabditis elegans; Contractility; alp-1 mutants; Z-disks; Kettin | 2009 |

Lindstrom, Gary E. | Alpha-beta pruning on evolving game trees | The alpha-beta strategy is a widely used method for economizing on the size of game trees. Heretofore, its application has been limited to depth-first tree growth in recursive search functions. However, many modern game players use retentive (i.e. coroutine-based) control to achieve greater attentio... | Alpha-beta pruning; Game trees | 1979 |

Capecchi, Mario R. | Altered enzymes in drug-resistant variants of mammalian tissue culture cells. | Two selective procedures are compared in an effort to isolate variants of mouse L cells containing structural gene mutations. Among the resulting variant cloned cell lines are found two types of alterations in theenzyme hypoxanthine phosphoribosyl transferase (EC 2.4.2.8.)

Churchwell, John C.; Lopez-Larson, Melissa; Yurgelun-Todd, Deborah A. | Altered frontal cortical volume and decision making in adolescent cannabis users | Anticipating future outcomes is central to decision making and a failure to consider long-term consequences may lead to impulsive choices. Adolescence is a vulnerable period during which underdeveloped prefrontal cortical systems may contribute to poor judgment, impulsive choices, and substance ab... | | 2010 |

Adler, Frederick R. | Alternating host cell tropism shapes the persistence, evolution and coexistence of Epstein-Barr virus infections in human | Epstein-Barr virus (EBV) infects and can persist in a majority of people worldwide. Within an infected host, EBV targets two major cell types, B cells and epithelial cells, and viruses emerging from one cell type preferentially infect the other. We use mathematical models to understand why EBV infec... | | 2011 |

Codding, Brian | Alternative aboriginal economies: Martu livelihoods in the 21st century | In the western deserts of Australia, hunting and gathering endures as an important social and economic activity. That foraging persists within the boundaries of developed industrialized nation states may come as a surprise to those who evaluate foraging as less profitable than agricultural, wage or ... | Aboriginal economics; Aboriginal foraging | 2015 |

Olivera, Baldomero M. | Alternative splicing in the pore-forming region of shaker potassium channels | We have cloned cDNAs for the shaker potassium channel gene from the spiny lobster Panulirus interruptus. As previously found in Drosophila, there is alternative splicing at the 59 and 39 ends of the coding region. However, in Panulirus shaker, alternative splicing also occurs within the pore-forming... | Panulirus interruptus; Conotoxins; Shaker; Stomatogastric ganglion; Pore-forming region; Alternative splicing | 1997 |

Coffin, Cheryl M.; Capecchi, Mario R. | Alveolar rhabdomyosarcomas in conditional Pax3:Fkhr mice: cooperativity of Ink4a/ARF and Trp53 loss of function. | Alveolar rhabdomyosarcoma is an aggressive childhood muscle cancer for which outcomes are poor when the disease is advanced. Although well-developed mouse models exist for embryonal and pleomorphic rhabdomyosarcomas, neither a spontaneous nor a transgenic mouse model of alveolar rhabdomyosarcoma has... | Cell Differentiation; Forkhead Transcription Factors; Myogenic Regulatory Factors | 2004-11-01 |

Hawkes, Kristen | Alyawara plant use and optimal foraging theory | Various authors have remarked on the importance of seeds in the pre-European diet of central Australian Aborigines. The Alyawara, an Arandic-speaking group, were typical in this respect. They collected edible seeds from nearly half the eighty-five plant species in their traditional subsistence inven... | Australia; Aborigines; Foraging; Seeds | 1981 |

Mattis, Daniel C.; Sutherland, Bill | Ambiguities with the relativistic δ-function potential | In many cases of physical interest, the 6-function potential is a very convenient approximation to more structured, and more difficult, short-ranged potentials. In relativistic theories, its use is often mandated because only a mathematical point has a relativistically invariant shape. Neverthele... | Delta function; Energy states | 1981-09 |
