| 426 |  | Wen, Ming | Air pollution shortens life expectancy and health expectancy for older adults: the case of China | Background: Outdoor air pollution is one of the most worrying environmental threats China faces today. Comprehensive and quantitative analysis of the health consequences of air pollution in China is lacking. This study reports age-sex-specific life expectancy (LE) and health expectancies (HEs) corre... | 2012-01-01 | |
| 427 |  | Scarpulla, Michael | Air shear driven flow of thin perfluoropolyether polymer films | We have studied the wind driven movement of thin perfluoropolyether (PFPE) polymer films on silicon wafers and CNx overcoats using the blow-off technique. The ease with which a liquid polymer film moves across a surface when sheared is described by a shear mobility xS , which can be interpreted both... | Perfluoropolyether; Polymer films; Air shear; Shear mobility | 2003 |
| 428 |  | Miller, Jan D. | Air sparged hydrocyclone for fine coal flotation | The cleaning of fine coal to achieve compliance specifications generally is a challenging problem for coal preparation engineers.

| 429 |  | Chapman, David S. | Air, ground, and groundwater recharge temperatures in an alpine setting, Brighton Basin, Utah | Noble 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 | |
| 430 |  | Lupton, John Mark | Air-induced fluorescence bursts from single semiconductor nanocrystals | We 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 bursts | 2004 |
| 431 |  | Miller, Jan D. | Air-sparged hydrocyclone (ASH) technology for cyanide recovery | An 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.

| 434 |  | Wu, Yong-Shi | Algebraic and geometric aspects of generalized quantum dynamics | We 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 identity | 1994-06 |
| 435 |  | Tasdizen, Tolga | Algebraic curves that work better | An 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 | |
| 436 |  | Wu, Yong-Shi | Algebraic solution for a two-level atom in radiation fields and the Freeman resonances | Using 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; Quasienergies | 2006-02 |
| 437 |  | Stevens, Kenneth | Algorithms for MIS vector generation and pruning | Ignoring 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 | |
| 438 |  | Crow, Franklin C. | The aliasing problem in computer-synthesized shaded images | This 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 algorithms | 1976 |
| 439 |  | McDaniel, Susan | Alice in demographyland: how it looks from the other side of the looking glass | The 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 life | 1992 |

| 442 |  | Firmage, Edwin B. | Allegiance and stewardship: holy war, just war, and the Mormon tradition in the nuclear age | The 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; Peacemakers | 1983 |
| 443 |  | 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.

| 446 |  | 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.

| 447 |  | 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 |
