Adhesion of copper to teflon surfaces modified by vacuum UV photo-oxidation downstream from Ar microwave plasma
(The American Chemical Society: Polymeric Materials Science and Engineering, 2004)Fluoropolymers, like Teflon(r) PTFE (polytetrafluoroethylene) and FEP (fluorinated ethylene-propylene co-polymer), have been extensively used in space applications, protective coatings, microelectronics packaging and ... -
Adhesion of copper to Teflon ® poly(tetrafluoroethylene-co-perfluoropropyl vinyl ether) (PFA) surfaces modified by vacuum UV photo-oxidation downstream from argon microwave plasma
(Materials Research Society Proceedings: Materials for Space Applications, 2005)Good practical adhesion of sputter-deposited Cu is achieved to poly(tetrafluoroethylene-co-perfluoropropyl vinyl ether) (PFA) surfaces at short treatment times of vacuum UV (VUV) photo-oxidation downstream from Ar ... -
Adjunct aids in instructional prose: a multimedia study deaf college students
(Oxford University Press, 1999): A computer-based science lesson was administered to 144 deaf college students grouped into low, middle, and high reading ability levels. Five instructional conditions were compared: (1) text only, (2) text and content ... -
Adsorption of a polymeric siloxane surfactant on carbon black particles dispersed in mixtures of water with polar organic solvents
(Elsevier: Journal of Colloid and Interface Science, 2002-11-01)The adsorption of a rake-type polymeric siloxane surfactant (polydimethylsiloxane-graft-polyether copolymer) on carbon black (CB) particles dispersed in mixtures of water with polar organic solvents (ethanol, formamide, ... -
Adsorption of hydrogen on carbon single-walled nanotubes as measured by the volumetric technique
(Materials Research Society Proceedings: Symposium A: Nanotubes and Related Materials, 2000)We report on hydrogen adsorption onto carbon single-walled nanotube (SWNT) material as measured by the volumetric technique. This method determines the amount adsorbed by monitoring the pressure in a known volume at a known ... -
The Advantages of ectothermy for tetrapods
(University of Chicago Press: American Naturalist, 1980-01)The way of life of amphibians and reptiles, in contrast to that of birds and mammals, is based on low energy flow. Many of the morphological and physiological characteristics of ectothermal tetrapods that are normally ... -
Aggregation effects on the structure and optical properties of a model PPV oligomer
(Elsevier: Synthetic Metals, 2001-03-15)We report the effects of solvent-induced aggregation on photoluminescence spectra, decay dynamics and quantum yield in trimers of MEH-PPV and compare these to analogous experiments on the high molecular weight polymer. ... -
Aggregation quenching of luminescence in electroluminescent conjugated polymers
(The American Chemical Society: Macromolecules, 1999-04-08)We report measurements of photoluminescence from films of a soluble phenylenevinylene polymer that has prospective importance as the emissive material in light-emitting diodes. We show unambiguously that there is long-lived ... -
Air bubble-induced light-scattering effect on image quality in 193 nm immersion lithography
(Optical Society of America, 2005-07-01)As an emerging technique, water immersion lithography, offers the capability of reducing critical dimensions by increasing the numerical aperture that is due to the higher refractive indices of immersion liquids than ... -
ALFRED: An allele frequency database for anthropology
(Wiley: American Journal of Physical Anthropology, 2002-09)The deluge of data from the human genome project (HGP) presents new opportunities for molecular anthropologists to study human variation through the promise of vast numbers of new polymorphisms (e.g., single nucleotide ... -
ALFRED: the ALelle FREquency Database. Update
(Oxford University Press: Nucleic Acids Research, 2003-01-01)Elaboration of ALFRED (http://alfred.med.yale.edu) is being continued in two directions. One of which is developing tools for efficiently annotating the entries and checking the integrity of the data already in the database ... -
Algorithmic regularization with velocity-dependent forces
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2006-05)Algorithmic regularization uses a transformation of the equations of motion such that the leapfrog algorithm produces exact trajectories for two-body motion as well as regular results in numerical integration of the ... -
All-optical double-sideband suppressed-carrier modulation of semiconductor lasers
(American Institute of Physics, 1998-06-15)We demonstrate theoretically and verify experimentally that injection locking may be used to achieve double-sideband suppressed-carrier modulation of semiconductor lasers. Our theoretical investigation explains the suppression ... -
Allelic variation at alcohol metabolism genes (ADH1B, ADH1C, ALDH2) and alcohol dependence in an American Indian population
(Springer: Human Genetics, 2003-09)Enzymes encoded by two gene families, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), mediate alcohol metabolism in humans. Allelic variants have been identified that alter metabolic rates and influence risk ... -
Ambient-stable blue luminescent silicon nanocrystals prepared by nanosecond-pulsed laser ablation in water
(2008 Optical Society of America, 2009-01-07)Even with intensive research, air-stable blue light emission from silicon nanocrystals (Si-ncs) at room temperature still remains a challenge. We show that stable and blue-luminescent Si-ncs can be produced by ... -
Amplitude modulation in a pair of time-delay coupled external-cavity semiconductor lasers
(Elsevier Science B.V., 2003-11-03)The phenomenon of amplitude death in coupled nonlinear oscillators has been a topic of recent interest. We demonstrate that a similar phenomenon can occur in a pair of time-delay coupled, external-cavity semiconductor ... -

An Analysis of persistence, resilience, and the conservation of keystone species
(Elsevier. The definitive version can be found at http://www.elsevier.com/locate/, 2000)Ecologists and economists are increasingly in agreement that ecological and economic systems are linked and that these systems should be viewed as one system. However, because this recognition has been recent, there are ... -
Analysis of spectrophotometer specular performance using goniometric information
(The International Society for Optical Engineering (SPIE), 2003-07)The 1986 Cifi document 15.2, Colorimetry, was necessarily broad in specifying the use of the gloss trap or specular port in integrating sphere measurements. This has led to a variety of spectrophotometer configurations ...
