426 Stevens, KennethAlgorithms for MIS vector generation and pruningIgnoring the effect of simultaneous switching for logic gates causes silicon failures for high performance microprocessor designs. The main reason to omit this effect is the run time penalty and potential over-conservatism. Run times are directly proportional to the vector sizes. Efficient algorithm...2006
427 Crow, Franklin C.The aliasing problem in computer-synthesized shaded imagesThis paper describes work toward improving the quality of computer-synthesized shaded images. Current (practical) hidden-surface algorithms produce an image whose precision is strictly limited by the number of picture elements. Problems caused by this limitation are described and explained in the t...aliasing problem; shaded images; hidden-surface algorithms1976
428 McDaniel, SusanAlice in demographyland: how it looks from the other side of the looking glassThe challenges are many in reflecting on women in demography in Canada in the 1990's. On the one hand, so much is known about women in academia and the hurdles that still need to be overcome " institutionally and intellectually. So much more research exists in the area than it did only a decade ago....Women; Universities; Academic life1992
429 Schvaneveldt, Nena; Stone, Sean; Brody, Erica R.; Clairoux, Natalie; Lubker, Irene M.; Nevius, Amanda M.; Porcello, Lorraine; Bissram, Jennifer S.Aligning Information Literacy and Evidence-Based Dentistry Concepts in a Rubric to Improve Dental EducationUnderstanding of the alignment of key concepts in both evidence-based dentistry and information literacy could lead to greater collaboration between librarians and dental faculty. To identify these areas of partnership, a group of dental librarians from across North America created a rubric aligning...curriculum; dental education; evidence-based dentistry; information literacy; standards
430 Armentrout, Peter B.Alkali metal cation interactions with 12-crown-4 in the gas phase: revisitedQuantitative interactions of alkali metal cations with the cyclic 12-crown-4 polyether ligand (12C4) are studied. Experimentally, Rb+(12C4) and Cs+(12C4) complexes are formed using electrospray ionization and their bond dissociation energies (BDEs) determined using threshold collision-induced dissoc...2012-01-01
431 Firmage, Edwin B.Allegiance and stewardship: holy war, just war, and the Mormon tradition in the nuclear ageThe present escalation in nuclear weapons technology between the United States and the Soviet Union has progressed beyond the point where any increase in such weaponry necessarily results in increased national security. It has become, in fact, the ultimate act of idolatry, a reliance upon technology...Nuclear weapons; Salvation; Peacemakers1983
432 Coley, Phyllis D.; Lokvam, John; Kursar, Thomas A.Allelochemic function for a primary metabolite: the case of L-tyrosine hyper-production in Inga umbellifera (Fabaceae)Young leaves of tropical forest trees experience far higher herbivory pressure than mature leaves of the same species. Selection on young leaves has led to diverse forms of defense chemical expression. Though most allelochemicals are secondary metabolites, allelochemic function for a primary metabol...5-amino-4-hydroxy-pentanoic acid; Panama; Barro Colorado Island; Fabaceae; Inga umbellifera; Primary metabolite; Heliothis virescens2006
433 Smith, Ken R.Allied health manpower strategies: estimates of the potential gains from efficient task delegationThis 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
434 Wolfinger, Nicholas H.Alone in the ivory tower: how birth events vary among male and female fast-track professionalsWe 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; Census2009-06-10
435 Beckerle, Mary C.ALP-enigma protein ALP-1 functions in actin filament organization to promote muscle structural integrity in Caenorhabditis elegansMutations 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; Kettin2009
436 Lindstrom, Gary E.Alpha-beta pruning on evolving game treesThe 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 trees1979

438 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.)

439 Churchwell, John C.; Lopez-Larson, Melissa; Yurgelun-Todd, Deborah A.Altered frontal cortical volume and decision making in adolescent cannabis usersAnticipating 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
440 Adler, Frederick R.Alternating host cell tropism shapes the persistence, evolution and coexistence of Epstein-Barr virus infections in humanEpstein-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

442 Codding, BrianAlternative aboriginal economies: Martu livelihoods in the 21st centuryIn 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 foraging2015
443 Olivera, Baldomero M.Alternative splicing in the pore-forming region of shaker potassium channelsWe 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 splicing1997

445 Hawkes, KristenAlyawara plant use and optimal foraging theoryVarious 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.

446 Mattis, Daniel C.; Sutherland, BillAmbiguities with the relativistic δ-function potentialIn 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 states1981-09
