751 Stringfellow, Gerald B.Bandgap control of GaInP using Sb as a surfactantThe use of surfactants to control specific aspects of the vapor-phase epitaxial growth process is beginning to be studied for both the elemental and III/V semiconductors. To date, most reported surfactant effects for semiconductors relate to the morphology of the growing films. However, semicondu...Band-gap energy; Growth process; Epitaxial growth1999-09-27
752 Stevens, KennethBandwidth optimization in asynchronous NoCs by customizing link wire lengthThe bandwidth requirement for each link on a network-on-chip (NoC) may differ based on topology and traffic properties of the IP cores. Available bandwidth on an asynchronous NoC link will also vary depending on the wire length between sender and receiver. We explore the benefit to NoC performance ...2010
753 DeTar, CarletonBaryon density correlations in high temperature hadronic matterAs part of an ongoing effort to characterize the high temperature phase of QCD, in a numerical simulation using the staggered fermion scheme, we measure the quark baryon density in the vicinity of a fixed test quark at high temperature and compare it with similar measurements at low temperature and ...Baryon density; Staggered fermions; Quark plasma1994-06
754 Mastrangelo, Carlos H.Batch fabrication of flowable colorimetric pressure sensing particles via surface micromachiningThe batch fabrication and test of artificial optical resonator slab-type micro particles (14 μm diameter, 0.7 μm gap) is presented as a means to map absolute pressure within microscopic environments. The pressure-sensing particles consist of a semi-transparent elastic polysilicon shell enclosi...2010
755 Morrow, CarolynBaudelaire as seen through Les Fleurs du MalModern phychology emphasizes the similarity of the dream to works of art, especially poetry. The dreamer or the poet works through symbols, which express his inner self, a self largely unknown to the conscious mind.1 There can be no "difference irreductible entre le 'moi' subjectif and le 'je' crea...1964
756 Solomon, Douglas KipBayesian evaluation of groundwater age distribution using radioactive tracers and anthropogenic chemicalsThe development of a Bayesian modeling approach for estimation of the age distribution of groundwater using radioactive isotopes and anthropogenic chemicals is described. The model considers the uncertainties associated with the measured tracer concentrations as well as the parameters affecting the ...2012-01-01
757 Ehleringer, James R.Bayesian integration of isotope ratio for geographic sourcing of castor beansRecent years have seen an increase in the forensic interest associated with the poison ricin, which is extracted from the seeds of the Ricinus communis plant. Both light element (C, N, O, and H) and strontium (Sr) isotope ratios have previously been used to associate organic material with geographic...2012-01-01
758 McDaniel, SusanBecoming inventors: women who aspire to inventDespite growing awareness of women's contributions to technological advances in the past, almost nothing is known about contemporary women inventors and the challenges they face. Although greater attention has been given recently to women's contributions to technology and innovation, understanding...Inventions; inventing; technology1990
759 Johnston, Susan S.Beginning augmentative communication systemsTo be unable to produce communicative behavior that can be understood by others represents one of the most frustrating experiences imaginable. Communicating through a communication board or with gestures lessens this frustration but does not eliminate it. Since 1975, remarkable advances have been ma...Intervention; Challenging behavior; Symbols1992
760 Miller, Jan D.The behavior of arsenic trioxide in non-ferrous extractive metallurgical processingStudy of the acid bake-leach process has shown potential advantages for the treatment of enargite (Cu3AsS4) concentrates. Among the most important advantages of the process is the transformation of enargite to water-soluble copper sulfate and highly soluble arsenic trioxide (arsenolite). Because ars...acid bake; enargite; vapor pressure; arsenolite; claudetite; copper sulfate2014-01-01
761 Codding, BrianBehavioral ecology and the future of archaeological scienceThe future of archaeological science relies as much (if not more) on theoretical as on methodological developments. As with anything in biology, explaining past human behavior will require the application of evolutionary theory. As with anything in archaeology, theory is useless without clear ties t...2015-01-01
762 Yaffe, JoanneBehaviorism, social learning, and exchange theoryBehaviorism focuses on learning and the way in which behavior is shaped by its antecedent conditions and consequences. In rejecting mentalistic constructs such as mind, consciousness, and other internal processes, behaviorism stresses the importance of studying observable behavior rather than pheno...2006
763 Vardeny, Zeev ValentineBelow-gap excitation of ∏-conjugated polymer-fullerene blends: implications for bulk organic heterojunction solar cellsWe used a variety of optoelectronic techniques such as broadband fs transient and cw photomodulation spectroscopies, electroabsorption, and short-circuit photocurrent in bulk heterojunctions organic solar cells for studying the photophysics in ∏-conjugated polymer-fullerene blends with below-gap...pi-conjugated polymers; Fullerene blends; Below-gap excitations; Bulk heterojunctions; Bulk organic heterojunction solar cells; Photophysics2008-07
764 Pershing, David W.Bench and pilot scale process evaluation of reburning for in-furnace NOx reductionThis paper describes a combined experimental and theoretical study which was undertaken to quantify the impact of fuel and process parameters on reburning effectiveness and provide the scaling information required for commercial application of reburning under highly varied industrial conditions.

765 Miller, Jan D.Bench scale flotation of alunite ore with oleic acidAlunite [KA13(SO4)2(OH)6] is a promising non-bauxitic aluminum resource, the domestic reserves of which are estimated to be 800 x 106 tons at 35 percent alunite. The major gangue mineral associated with alunite is quartz. The thermochemical process that has been developed for treatment of this ore...mesh; separation; liberation1980
766 Miller, Jan D.Bench scale flotation of sedimentary phosphate rock with hydroxamic acid collectorsIt has been discovered that water insoluble alcoholic solutions of alkyl hydroxamic acids serve as selective collectors for the flotation of phosphate mineral resources. The effectiveness of the new collector chemistry has been demonstrated by the results from single stage bench scale flotation exp...flotation; insoluble collectors; hydroxamic acid; alcohol; phosphate rock; high solids conditioning; particle size2002

768 Liu, FengBending of nanoscale thin Si film induced by growth of Ge islands: hut vs. domeWe perform atomistic simulations to compute bending of freestanding nanoscale thin Si film induced by strained Ge islands. We show that a larger Ge dome island can induce smaller bending than a smaller hut island and explain the surprising experimental observation for growth of Ge islands on pattern...Bending; Nanoscale thin Si film; Ge islands; Hut islands; Dome islands; Atomistic simulations2004
769 Liu, FengBending of nanoscale ultrathin substrates by growth of strained thin films and islandsMechanical bending is ubiquitous in heteroepitaxial growth of thin films where the strained growing film applies effectively an "external" stress to bend the substrate. Conventionally, when the deposited film is much thinner than the substrate, the bending increases linearly with increasing film th...Nanoscale ultrathin substrates; Strained thin films; Islands; Heteroepitaxial growth; Si substrate; Ge film2005-08
770 Goldberg, Robert A.Beneath the hood and robe: a socioeconomic analysis of Ku Klux Klan membership in Denver, Colorado, 1921-1925The Invisible Empire of the Knights of the Ku Klux Klan was in numbers and political influence the most powerful social movement of the 1920s and probably the most significant crusade of the American right-wing. Unlike its predecessor of the Reconstruction period or its descendant of today, this Kla...1980
771 Coley, Phyllis D.Beneficios y costos de defensa en un arbusto del neotrópicoLOS beneficios y costos son de importancia capital para las teorfas de optimization de las defensas de las plantas.

773 Coley, Phyllis D.Benefits and costs of defense in a neotropical shrubBenefits and costs are central to optimality theories of plant defense. Benefit is the gain in fitness to reducing herbivory and cost is the loss in fitness to committing resources to defense. We evaluate the benefits and costs of defense in a neotropical shrub, Psychotria horizontalis.
