426 Chapman, David S.Air, ground, and groundwater recharge temperatures in an alpine setting, Brighton Basin, UtahNoble gases are useful tracers for constraining groundwater recharge temperature and elevation, critical in determining source areas of groundwater recharge in mountainous terrain. A monitoring network in the alpine Brighton Basin in the Wasatch Mountains of northern Utah, USA, was established to ex...2012-01-01
427 Lupton, John MarkAir-induced fluorescence bursts from single semiconductor nanocrystalsWe observe a dramatic enhancement of the fluorescence intensity from single core/shell CdSe/ZnS nanocrystals upon sudden exposure to air from an evacuated surrounding. Both the number of particles contributing to emission increases as well as the average emission intensity from a single particle, le...CdSe; ZnS; Air-induced; Fluorescence bursts2004
428 Miller, Jan D.Air-sparged hydrocyclone (ASH) technology for cyanide recoveryAn air-sparged hydrocyclone (ASH) mobile system was evaluated for continuous stripping and recovery of cyanide (the AVR process) from process water at a gold plant site. The ASH unit performed exceptionally well as an absorber. HCN was absorbed from the gas phase in a single pass with an efficiency...Cyanide recovery; Air-sparged hydrocyclone; Gold processing; Process water2005

431 Wu, Yong-ShiAlgebraic and geometric aspects of generalized quantum dynamicsWe briefly discuss some algebraic and geometric aspects of the generalized Poisson bracket and noncommutative phase space for generalized quantum dynamics, which are analogous to properties of the classical Poisson bracket and ordinary symplectic structure.Quantum dynamics; Jacobi identity1994-06
432 Tasdizen, TolgaAlgebraic curves that work betterAn algebraic curve is defined as the zero set of a polynomial in two variables. Algebraic curves are practical for modeling shapes much more complicated than conics or superquadrics. The main drawback in representing shapes by algebraic curves has been the lack of repeatability in fitting algebraic...1999
433 Wu, Yong-ShiAlgebraic solution for a two-level atom in radiation fields and the Freeman resonancesUsing techniques of complex analysis in an algebraic approach, we solve the wave equation for a two-level atom interacting with a monochromatic light field exactly. A closed-form expression for the quasienergies is obtained, which shows that the Bloch-Siegert shift is always finite, regardless of ...Bloch-Siegert shift; Freeman resonances; Quasienergies2006-02
434 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
435 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
436 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
437 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
438 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
439 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
440 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
441 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
442 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
443 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

450 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
