Salt excretion in a beach lizard (Ameiva quadrilineata, Teiidae)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1976-01)The teiid lizardAmeiva quadrilineata has a nasal salt gland that responds to NaCl loading by increasing excretion of Na+ (from 1.12 to 2.63 uM/100 gh), K+ (from 0.14 to 2.43 uM/100 gh), and Cl– (from 1.10 to 5.47 uM/100 ... -
Sarbanes-Oxley: are audit committees up to the task?
(Emerald. The definitive publisher's copy can be found at: www.emeraldinsight.com/0268-6902.htm, 2007)The Sarbanes-Oxley Act (2002) (hereafter, SOX or the Act) brought forth sweeping changes in corporate governance practices in the US. The Act stipulates more stringent internal control requirements, demands more timely ... -
Scanning tunneling optical resonance microscopy (STORM)
(Materials Research Society Proceedings: 2002 Fall Meeting: Symposium G, 2003)The ability to determine the in-situ optoelectronic behavior of semiconductor materials has become especially important as the size of device architectures are reduced and the development of complex microsystems has ... -

Seasonal seawater optical properties of the U.S. Middle Atlantic Bight
(American Geophysical Union, 1996)Optical properties of seawater on the U.S. Middle Atlantic Bight (MAB) were measured during four cruises spanning 1993-1994. Samples were collected in August and November 1993 and March and April 1994 along a cruise track ... -
Seasonal variation of CDOM in the Middle Atlantic Bight: terrestrial inputs and photooxidation
(The International Society for Optical Engineering (SPIE), 1997-02)Surveys of the fluorescence and absorption of chromophore-containing dissolved organic matter (CDOM) were made along a cruise line extending from the mouth of Delaware Bay southeast to the Sargasso Sea. With shallow ... -
Security considerations in wireless sensor networks
(Elsevier Science, 2005-01)In future smart environments, ad hoc sensor networks will play a key role in sensing, collecting, and disseminating information about environmental phenomena. As sensor networks come to be wide-spread deployment, security ... -
Selenide versus sulfide centers on (100) AgIBr surfaces: characterization and energy levels
(Maney Publishing on behalf of the Royal Photographic Society, 2003)Sensitometric and spectroscopic techniques are used to characterize sensitizer centers produced by sulfur and selenium sensitization of AgIBr cubes. Sulfur sensitization primarily affects the long-wavelength sensitivity ... -
Self-organization of coupled nonlinear oscillators
(EDP Sciences, 1998-12-01)The effects of impurities introduced into a lattice of strongly coupled oscillators are studied. Contrary to our expectations, a single impurity can control the chaotic behavior of a long array of chaotic oscillators and ... -
Sense from sensitivity and variation of parameters
(Elsevier Science B.V., Amsterdam, 2006-03)It is known that Alekseev’s variation of parameters formula for ordinary differential equations can be generalized to other types of causal equations (including delay differential equations and Volterra integral equations), ... -
Sensitized carrier generation in evaporated thin films and particle dispersions of benzimidazole perylene
(International Society for Optical Engineering, 1999-10)We studied photoconductivity in particle dispersions and vacuum evaporated films of benzimidazole perylene (BZP) pigment in contact with a tetraphenyldiamine (TPD) hole transport layer. Xerographic photoreceptors based on ... -
Separation, detection, and quantification of imine-linked opines by high-performance liquid chromatography
(Elsevier: Journal of Chromatography, 1998-07-17)Protocols for reversed-phase high-performance liquid chromatography (RP-HPLC) with fluorescence detection were developed for the separation, detection and quantification of imine-linked opines, following 4-fluoro-7-nitro ... -
Seyferts on the edge: Polar scattering and orientation-dependent polarization in Seyfert 1 nuclei
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2004-05)We have identified 12 Seyfert 1 galaxies that exhibit optical polarization spectra similar to those of Seyfert 2 galaxies in which polarized broad-lines are detected. We present new spectropolarimetric observations of 3 ... -

Simulated color gamut mapping using simple rendered images
(The International Society for Optical Engineering (SPIE), 1996-03)In order to systematically evaluate different gamut mapping algorithms, we have simulated gamut mapping on a CRT using simple rendered images of colored spheres floating in front of a gray background. Using CIELab as our ... -
Simulation study of changes in ultrasound speckle statistics with the system point spread function
(Journal of the Acoustical Society of America, 1994)The intensity point signal-to-noise ratio, SNRI, characterizing the ultrasound speckle statistics, depends on the tissue scattering microstructure and the imaging systems point spread function. Both should be described in ... -
Single wall carbon nanotube-Nafion composite actuators
(The American Chemical Society: Nano Letters, 2002-11)Single wall carbon nanotube (SWNT)-Nafion composite actuators have been demonstrated for 0.1-18% w/w doping of purified SWNTs within the polymer matrix. The high purity SWNTs, >95% w/w, were homogeneously dispersed into ... -
Single wall carbon nanotube-polymer solar cells
(NASA: Glenn Research Center Technical Reports, 2005)Investigation of single wall carbon nanotube (SWNT)-polymer solar cells has been conducted towards developing alternative lightweight, flexible devices for space power applications. Photovoltaic devices were constructed ...
