Light scattering and phase behavior of lysozyme-PEG mixtures
(Elsevier, 2006-03-03)Measurements of liquid-liquid phase transition temperatures (cloud points) of mixtures of a protein (lysozyme) and a polymer, poly(ethylene glycol) (PEG) show that the addition of low molecular weight PEG stabilizes the ... -
Line balancing and productivity improvements in electronics assembly using modeling and simulation techniques
(SMTA: SMTA Pan Pacific Microelectronics Symposium, 2002)The study presented in this paper was to model, simulate and analyze the performance of three existing assembly lines, in an electronics assembly facility, and suggest modifications to the lines, in order to improve machine ... -
Linear pixel shuffling for image processing, an introduction
(International Society for Optical Engineering (SPIE), 1993-04)We investigate a method of ordering pixels (the elements of a rectangular matrix) based on an arithmetic progression with wrap-around (modular arithmetic). For appropriate choices of the progression's parameters, based on ... -
Linear stability conditions for a first-order three-dimensional discrete dynamic
(Elsevier Science B.V., Amsterdam, 2004-04)Linear stability conditions for a first-order three-dimensional discrete dynamic are derived in terms of the trace, determinant, and sum of principle minors of the Jacobian evaluated at the equilibrium. -
Linewidth broadening across a dynamical instability
(Elsevier Science B.V., 1998-12-21)We investigate experimentally and theoretically the variation of the emission linewidth of an optically-injected semiconductor laser across a resonant period-doubling bifurcation. Close to the dynamical instability, the ... -
A liquid culture method for rescuing immature embryos of eastern cottonwood
(Springer: Plant Cell, Tissue and Organ Culture, 1987-01)A one-step method to rescue immature embryos of eastern cottonwood (Populus deltoides Bartr.) is described. Plantlets developed from 83% of 25-day-old embryos grown in shaken culture on Murashige and Skoog (MS) liquid ... -
Liver aldolase anomeric specificity
(American Chemical Society: Biochemistry, 1980-06-10)Stopped-flow kinetic studies of liver aldolase and of mixed liver-muscle aldolase catalyzed reactions of fructose 1,6-bisphosphate (FBP) have been carried out and interpreted by computer simulation. These experiments ... -
Localized synchronization in two coupled nonidentical semiconductor lasers
(American Physical Society, 1997-06-23)The dynamics of two mutually coupled but nonidentical semiconductor lasers are studied experimentally, numerically, and analytically for weak coupling. The lasers have dissimilar relaxation oscillation frequencies and ... -
Long- and short-chain plant-produced bacterial n-acyl-homoserine lactones become components of phyllosphere, rhizosphere, and soil
(American Phytopathological Society: Molecular Plant-Microbe Interactions, 2006-03)Two N-acyl-homoserine lactone (acyl-HSL) synthase genes, lasI from Pseudomonas aeruginosa and yenI from Yersinia enterocolitica, were introduced into tobacco, individually and in combination. Liquid chromatograph–tandem ... -
Louis Leon Thurstone in Monte Carlo: creating error bars for the method of paired comparison
(The International Society for Optical Engineering (SPIE), 2003-12)The method of paired comparison is often used in experiments where perceptual scale values for a collection of stimuli are desired, such as in experiments analyzing image quality. Thurstone’s Case V of his Law of Comparative ... -

Low pump limit of the bifurcation to periodic intensities in a semiconductor laser subject to external optical feedback
(American Physical Society, 1997-06)The conditions for a bifurcation to periodic intensities (Hopf bifurcation) for low values of the pump current are examined using singular perturbation methods. We show that the frequency of the oscillations at the bifurcation ... -
Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model
(Institute of Physics, 2001-08)We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity semiconductor lasers by utilizing a simplified, three-dimensional model derived from the infinite-dimensional Lang-Kobayashi (LK) ... -
Luminescence efficiency and time dependence in a high electron affinity conjugated polymer
(Elsevier: Synthetic Metals, 1996-01)We report measurements of the efficiency and time dependence of photoluminescence in a high electron affinity cyano-substituted derivative of poly (p-phenylenevinylene). In solution the photoluminescence quantum yield is ... -
Luminescent colloidal silicon nanocrystals prepared by nanoseconds laser fragmentation and laser ablation in water
(Materials Reseach Society (MRS), 2008-03)The surface states of silicon nanocrystals (Si-ncs) considerably affect quantum confinement effects and may determinate final nanocrystals properties. Colloidally dispersed Si-ncs offer larger freedom for surface modification ... -
Magnetic field mapping
(Wiley: Magnetic Resonance in Medicine, 1988-02)Homogeneous radiofrequency magnetic fields are necessary for production of high-quality magnetic images and for most forms of magnetic resonance spectroscopy. It is often convenient to map the radiofrequency homogeneity ... -
Mainstreaming the deaf student
(Journal of Disability Policy Studies, 1991)In most areas of special eduction, Public Law 94-142 has been hailed as a breakthrough. By stipulating that children with disabilities be educated with the least restrictive environment, the law promotes schooling of these ... -
Major loci influencing serum triglyceride levels on 2q14 and 9p21 localized by homozygosity-by-descent mapping in a large Hutterite pedigree
