Brighter, more colorful colors and darker, deeper colors based on a theme of brilliance
Authors: Heckaman Rodney L. , Fairchild Mark D. 
Published: June 2010

AbstractA methodology for achieving brighter, more colorful colors and deeper, darker colors based on Evans' zero gray (G0) [described in The Perception of Color] and his concept of brilliance as a percept in color vision was demonstrated and tested psychometrically in media produced under current digital video and digital cinema standards—basically the sRGB set of primaries. Objects or surfaces in a scene represented in sRGB as having gray content in the Evans sense are rendered as original. Flesh tones are preserved. Those features not having gray content—a highly colorful arrangement of flowers, a clear blue sky, and the glossy red lipstick of a beautiful lady—are made brighter, more colorful and deeper, darker when rendered in a set of primaries that emulate, for example, the xvYCC‐encoded standard and whose colors extend beyond those of sRGB—an expanded gamut, if you will. In all but the most‐aggressive application, versions of scenes where this methodology was applied were consistently preferred over the sRGB version across 10 representative scenes and 17 observers. © 2010 Wiley Periodicals, Inc.

Improved active‐diode circuit used in voltage doubler
Authors: Jia Jingbin , Leung Ka Nang 
Published: June 2010

SUMMARYAn improved active‐diode circuit, which makes use of positive feedback to achieve fast on/off transition, is presented in this paper. The proposed active‐diode circuit can be embedded into a voltage doubler to replace the commonly used dead‐time circuit and to eliminate reverse current. In addition, the relationship between oscillation frequency, boosting and output capacitances, load‐ and on‐resistances of the power switch and the output voltage is analysed, to investigate a methodology to retain high voltage gain of a voltage doubler. The proposed active‐diode circuit is applied to a voltage doubler implemented in a commercial 0.35‐µm process with threshold voltage of about 0.68 V. The input voltage, maximum output current and oscillation frequency of the voltage doubler are 1 V, 1 mA and 0.4 MHz, respectively. Moreover, the used boosting and output capacitances are 22 nF. The highest power efficiency achieved is 83% at a load current of 0.47 mA. Copyright © 2010 John Wiley & Sons, Ltd.
Luminescence of the solid complexes of acridine orange with RNA
Authors: Kapuscinski Jan , Darzynkiewicz Zbigniew , Melamed Myron R. 
Published: June 2010

AbstractThe products of interaction between acridine orange (AO) and natural RNA, or the synthetic RNA homopolymers are precipitates insoluble over a wide range of ionic strength. These complexes have a composition of 1 AO molecule per 1 phosphatate. The reaction is highly cooperative and the complex exhibits metachromatic luminescence. Significant differences in the luminescence spectra, related to base composition of RNA, characterize the insoluble complexes. This observation suggests that dye‐base interactions take place in the AO‐RNA complexes.During titration of poly(rA) with AO and simultaneous measurement of the luminescence and light scatter a two‐step formation of the particles could be detected. The cooperative binding of the ligand at D/P < 0.6 coincides with formation of small particles (molecular aggregates or micelles) and is followed at D/P > 0.6 by a cooperative agglomeration; the product of this agglomeration is particles of the size 0.35 μm and larger.Evidence is presented that suggests that the long wavelength luminescence (∼ 650 nm) is a consequence of the solute‐solid state transition of the AO‐RNA interaction product rather than the classic dye‐dye interactions previously visualized in the stacking model. Since these novel observations cannot be fully explained by the previously postulated molecular mechanisms of AO binding, an alternative model is advanced. Its implications in quantitative cytochemistry of nucleic acid as applied to flow cytometry are discussed.
Flexible sorting decision and droplet charging control electronic circuitry for flow cytometer‐cell sorters
Authors: McCutcheon Mark J. , Miller Richard G. 
Published: June 2010

AbstractWe describe sorting decision and droplet charging control electronic circuitry for a flow cytometer–cell sorter. The circuitry can handle up to five independent input signals and can sort in up to four directions. A sixth input channel is used to determine the presence or absence of an event requiring analysis. Sorting decisions are stored in a read‐only memory semiconductor device. All the input signals for a given event are reexpressed as either 0 or 1 and are used to define an address in this memory which contains the desired sorting outcome for the event. A set of switches enables one to choose between many different procedures for relating input cell pulses to sorting outcomes by switching to different blocks of the memory. The circuitry has been found capable of purity of cell separation to the level permitted by “deadtime” in the preceding analog stages. It is in regular use with the Ontario Cancer Institute flow cytometer–cell sorter.
Three‐color fluorescence measurements on single cells excited at three laser wavelengths
Authors: Steinkamp John A. , Stewart Carleton C. , Crissman Harry A. 
Published: June 2010

AbstractA three‐laser flow cytometer for quantitative analysis and sorting of cells and microscopic particles has been developed and evaluated using argon‐ and krypton‐ion lasers as excitation sources. Cells stained with three fluorescent dyes having different excitation spectra enter a flow chamber where they first pass through an electronic volume sensor and then intersect three spatially separated laser beams for fluorescence excitation of bound dyes and light scatter measurements. Separate pairs of beam‐shaping optics independently position and focus each beam onto the cell stream thus permitting cells to be sequentially illuminated. Fluorescence is measured by a detector that employs a single collecting lens for single or multilaser excitation experiments. Fluorescence signals are processed and displayed as frequency distribution histograms using an LSI‐11 computer. This instrument is described in detail with illustrative examples using cells stained for DNA content, protein, and cell surface antigens and cells that have phagocytized fluorescent microspheres.
Induction of chromosome damage by ultraviolet light and caffeine: Correlation of cytogenetic evaluation and flow karyotype
Authors: Cremer C. , Cremer T. , Gray J. W. 
Published: June 2010

AbstractAsynchrononously growing cells of a M3‐1 Chinese hamster line were ultraviolet (UV) irradiated (λ = 254 nm) with UV fluences up to 7.5 J/m2. After irradiation, cells were incubated with or without 2 mM caffeine for 20 hr, then mitotic cells were selected by mechanical shaking. Their chromosomes were isolated, stained with Hoechst 33258 and chromomycin A3, and measured flow cytometrically. While the fluorescence distributions of chromosomes (flow karyotypes) from cells treated with UV alone or with caffeine alone were very similar to those of untreated controls, the flow karyo‐types of UV + caffeine‐treated cells showed a debris continuum that increased with increasing UV fluence suggesting an increased number of chromosome fragments. Visual evaluation of metaphase plates revealed that the percentage of cells with chromosome damage also increased steadily with increasing UV fluence. A high degree of correlation was observed between the relative magnitude of the debris level from flow karyotypes and the percentage of cells with chromosome damage and with generalized chromosome shattering, respectively, as determined from metaphase spreads.
Quantification of mammalian sperm morphology by slit‐scan flow cytometry

Published: June 2010

AbstractThe head shapes of mammalian sperm have been measured by slit‐scan flow cytometry (SSFCM). In this approach, the distribution of fluorescence along acriflavine stained mammalian sperm is recorded and used as a measure of head shape. Fluorescence profiles were measured for sperm from mice, rabbits, hamsters, and bulls, and for sperm from mice exposed to testicular x‐irradiation from 0 to 900 rads. The profiles for sperm from nonirradiated animals were characteristic of each species and were reproducible from sperm to sperm. Some of the fluorescence profiles for sperm from the irradiated mice differed significantly from the profiles usually measured for sperm from unexposed mice. An algorithm was developed to determine the frequency of these sperm. The estimated frequencies of atypical profiles correlated well (r = 0.99) with the frequencies of abnormally shaped sperm determined by microscopic scoring. The maximum SSFCM sensitivity (minimum detectable dose = 199 rad) was not as high as that for the visual assay (minimum detectable dose = 116 rad). However, only 100 profiles were measured by SSFCM at each dose while at least 500 sperm were scored visually at each dose. The sensitivity of the SSFCM assay should be increased substantially by measuring more profiles. The objective nature of SSFCM coupled with the high correlation with results from the visually based assay of morphology suggests the use of SSFCM to measure frequencies of misshapen sperm when testing for mutagens or monitoring for effects of environmental contaminants.
