Filtering refers to exclusion of bad probes on the array or the whole array. Visual inspection of array images and color-coded plot images are the first tools that should be used to detect outlier probes or arrays [23]. Clustering (described below) is another common way to identify outlier array among the whole set of arrays in a study. [Pg.652]

Fig. 4. In vivo bioluminescent monitoring of the progression of P. mirabilis Xen 44 in the mouse model of catheter-induced urinary track infection (UTI). The ascending nature of uropathogen from the bladder up the ureters and to the kidney can be clearly visualized from outside intact live animals using luciferase tag pathogen and bioluminescence imaging. (See Color Plate 8, following p. 46.)... Fig. 4. In vivo bioluminescent monitoring of the progression of P. mirabilis Xen 44 in the mouse model of catheter-induced urinary track infection (UTI).

Mixing visualization using 1 gM fluorescein solution in mixer with breakup obstructions at increasing distances downstream. Fluorescein solution is flowing in the upper portion of the images (pseudo colored green) and water in the lower portion. Pixel intensity line scans across the microchannel cross-section at (b) the entrance and (c) 5 mm downstream [22]... [Pg.2185]

FIGURE 7.46 SEM (a, b) and TEM (c, d) images show a mixture of polyaniline nanofibers and polystyrene spheres (a, c) before and (b, d) after flash welding. The inset shows the visual color contrast between unexposed (e, bluish white) and exposed (f, dark blue) areas. (Adapted from Huang, J.X. and Kaner, R.B., Nat. Mater., 3, 783-786, 2004.)... [Pg.244]

Color - A term sometimes used to define wavelength or spectral interval, as in two-color radiomehy (meaning a method that measures in two spectral intervals) also used conventionally (visual color) as a means of displaying a thermal image, as in color thermogram. [Pg.157]

Once the job is completed, the UniChem GUI can be used to visualize results. It can be used to visualize common three-dimensional properties, such as electron density, orbital densities, electrostatic potentials, and spin density. It supports both the visualization of three-dimensional surfaces and colorized or contoured two-dimensional planes. There is a lot of control over colors, rendering quality, and the like. The final image can be printed or saved in several file formats. [Pg.332]

Theory and Equipment. Many diseases of the human body can be identified by visual appearance. Tumors in the upper gastrointestinal (GI) tract, for example, possess a characteristic salmon pink color (3). The presence of such a color can be an indication of disease. Endoscopy is the medical imaging tool used to detect such colors in the inside of hoUow internal organs such as the rectum, urethra, urinary bladder, stomach, colon, etc. An endoscope is the instmment used to perform endoscopy. Endoscopic imaging involves the production of a tme color picture of the inside of the human body using lenses and either hoUow pipes, a fiber optic bundle, or a smaU CCD camera. AU three use a large field-of-view, sometimes referred to as a fish eye, lens to aUow a 180° field of view. [Pg.48]

Threshold contrast is illustrated in Fig. 10-2. / is the intensity of light received by the eye from the object, and / + A/ represents the intensity coming from the surroundings. The threshold contrast can be as low as 0.018-0.03 and the object can still be perceptible. Other factors, such as the physical size of the visual image on the retina of the eye and the brain s response to the color of the object, influence the perception of contrast. [Pg.138]

ELF can be visualized with different kinds of images. Colored sections through a molecule are popular, using white for high values of ELF, followed by yellow-red-violet-blue-dark blue for decreasing values simultaneously, the electron density can be depicted by the density of colored points. Contour lines can be used instead of the colors for black and white printing. Another possibility is to draw perspective images with iso surfaces, i.e. surfaces with a constant value of ELF. Fig. 10.2 shows iso surfaces with ELF = 0.8 for some molecules from experience a value of ELF = 0.8 is well suited to reveal the distribution of electron pairs in space. [Pg.89]

The data can be visualized in several formats. In a gel image, the optical density at each point is related to the fluorescence intensity false color images can be used to improve the dynamic range of visualization. We usually employ a logarithmic compression to help visualize the wide dynamic range of the data the image can be processed to saturate the most intense components, allowing observation of less intense components. [Pg.356]
