Spatial gamut mapping for preserving the details of an image  

NASA Astrophysics Data System (ADS)

The spatial gamut-mapping algorithm (SGMA) overcomes the drawbacks of the widely used color-by-color methods. Spatial gamut mapping can preserve detailed information in original images by performing adaptive gamut mapping in surrounding pixels within the image. However, spatial gamut mapping can result in hue shift and the halo effect. In addition, it only preserves the boundary information outside the color gamut; the resulting gamut-mapped image does not sufficiently preserve the detailed information in the input image. In this paper, we propose an SGMA that utilizes details of the input image. Our approach improves detail that is not effectively represented with conventional spatial gamut mapping. This is done by taking an original image and first implementing gamut mapping of the input image. Then, the details of the input image and gamut-mapped image are extracted. By examining the out-of-gamut region, the details of the input image can be preserved when these values are added to the gamut-mapped image. The resulting image is obtained by clipping out-of-gamut pixels, since these pixels are generated in the process of preserving details. We demonstrated that images obtained using the proposed method are more similar to the input images, compared to images obtained using conventional methods.

Detailed method of estimation of wind energy output at a place  

SciTech Connect

In this paper detailed analysis of wind energy output at 10 places based on IMD data (1958-68) are presented. Windspeeds are recorded and averaged over definite time intervals. When estimating the energy in the wind flowing through unit area in unit time, called wind energy flux (WEF), the cube of the wind speed is required. When the wind speed is averaged, periods of high wind speeds are balanced against periods of low wind speeds. Applying a cube relationship emphasises the high wind speeds more than the low wind speeds. Thus the longer the averaging intervals, the greater the smoothing effect and the smaller the estimate of the WEF. Smyth and Cherry analysed 16 years of hourly data from 10 anemometer stations throughout New Zealand. They derived empirical methods for estimating the mean WEF that would have been given by hourly mean wind speeds using longer period data, such as daily mean wind speeds.

Subsequently, Three kinds of important image denosing schemes are introduced in this paper: one is image denosing based on the adaptive parameter estimation total variation model, which denosing the images based on region energy distribution; the second is using G norm on the perception scale, which provides a more intuitive understanding of this norm; the final is multi-scale denosing decomposition. The above methods involved can preserve more structures of biomedical images texture detail. Furthermore, this paper demonstrates the applications of those three methods. In the end, the future trend of biomedical images texture detail denosing Based on PDE is pointed out.

Fusion of visible and infrared images using saliency analysis and detail preserving based image decomposition  

NASA Astrophysics Data System (ADS)

Image fusion for visible and infrared images is a significant task in image analysis. The target regions in infrared image and abundant detail information in visible image should be both extracted into the fused result. Thus, one should preserve or even enhance the details from original images in fusion process. In this paper, an algorithm using pixel value based saliency detection and detail preserving based image decomposition is proposed. Firstly, the multi-scale decomposition is constructed using weighted least squares filter for original infrared and visible images. Secondly, the pixel value based saliency map is designed and utilized for image fusion in different decomposition level. Finally, the fusion result is reconstructed by synthesizing different scales with synthetic weights. Since the information of original signals can be well preserved and enhanced with saliency extraction and multi scale decomposition process, the fusion algorithm performs robustly and excellently. The proposed approach is compared with other state-of the-art methods on several image sets to verify the effectiveness and robustness.

Novel contrast enhancement scheme for infrared image using detail-preserving stretching  

NASA Astrophysics Data System (ADS)

A novel contrast enhancement scheme for infrared (IR) image using detail-preserving stretching (DPS) is presented in this paper. Unlike CCD images, the histogram of the IR images is not distributed to the entire dynamic range of the input image. Therefore, in order to enhance the contrast, the proposed method adopts contrast stretching since it has a low computational complexity and preserves the global contrast of the original. However, the stretching often produces unpleasant images that do not contain clear details by limiting the output dynamic range. To solve this problem, we propose a new contrast stretching method based on gradient-domain processing (GDP) that can enhance the local image contrast while preserving the global contrast as well as the image details. Experimental results demonstrate that the proposed method outperforms the conventional stretching-based and other image enhancement methods with respect to the visual quality and computational complexity.

DETAILED DECOMPOSITION OF GALAXY IMAGES. II. BEYOND AXISYMMETRIC MODELS  

SciTech Connect

We present a two-dimensional (2D) fitting algorithm (GALFIT, ver. 3) with new capabilities to study the structural components of galaxies and other astronomical objects in digital images. Our technique improves on previous 2D fitting algorithms by allowing for irregular, curved, logarithmic and power-law spirals, ring, and truncated shapes in otherwise traditional parametric functions like the Sersic, Moffat, King, Ferrer, etc., profiles. One can mix and match these new shape features freely, with or without constraints, and apply them to an arbitrary number of model components of numerous profile types, so as to produce realistic-looking galaxy model images. Yet, despite the potential for extreme complexity, the meaning of the key parameters like the Sersic index, effective radius, or luminosity remains intuitive and essentially unchanged. The new features have an interesting potential for use to quantify the degree of asymmetry of galaxies, to quantify low surface brightness tidal features beneath and beyond luminous galaxies, to allow more realistic decompositions of galaxy subcomponents in the presence of strong rings and spiral arms, and to enable ways to gauge the uncertainties when decomposing galaxy subcomponents. We illustrate these new features by way of several case studies that display various levels of complexity.

Hundred metre virtual telescope captures unique detailed colour image  

NASA Astrophysics Data System (ADS)

A team of French astronomers has captured one of the sharpest colour images ever made. They observed the star T Leporis, which appears, on the sky, as small as a two-storey house on the Moon [1]. The image was taken with ESO's Very Large Telescope Interferometer (VLTI), emulating a virtual telescope about 100 metres across and reveals a spherical molecular shell around an aged star. ESO PR Photo 06a/09 The star T Leporis as seen with VLTI ESO PR Photo 06b/09 The star T Leporis to scale ESO PR Photo 06c/09 A virtual 100-metre telescope ESO PR Photo 06d/09 The orbit of Theta1 Orionis C ESO PR Video 06a/09 Zoom-in onto T Leporis "This is one of the first images made using near-infrared interferometry," says lead author Jean-Baptiste Le Bouquin. Interferometry is a technique that combines the light from several telescopes, resulting in a vision as sharp as that of a giant telescope with a diameter equal to the largest separation between the telescopes used. Achieving this requires the VLTI system components to be positioned to an accuracy of a fraction of a micrometre over about 100 metres and maintained so throughout the observations -- a formidable technical challenge. When doing interferometry, astronomers must often content themselves with fringes, the characteristic pattern of dark and bright lines produced when two beams of light combine, from which they can model the physical properties of the object studied. But, if an object is observed on several runs with different combinations and configurations of telescopes, it is possible to put these results together to reconstruct an image of the object. This is what has now been done with ESO's VLTI, using the 1.8-metre Auxiliary Telescopes. "We were able to construct an amazing image, and reveal the onion-like structure of the atmosphere of a giant star at a late stage of its life for the first time," says Antoine Mérand, member of the team. "Numerical models and indirect data have allowed us to imagine the appearance of the star before, but it is quite astounding that we can now see it, and in colour." Although it is only 15 by 15 pixel across, the reconstructed image shows an extreme close-up of a star 100 times larger than the Sun, a diameter corresponding roughly to the distance between the Earth and the Sun. This star is, in turn, surrounded by a sphere of molecular gas, which is about three times as large again. T Leporis, in the constellation of Lepus (the Hare), is located 500 light-years away. It belongs to the family of Mira stars, well known to amateur astronomers. These are giant variable stars that have almost extinguished their nuclear fuel and are losing mass. They are nearing the end of their lives as stars, and will soon die, becoming white dwarfs. The Sun will become a Mira star in a few billion years, engulfing the Earth in the dust and gas expelled in its final throes. Mira stars are among the biggest factories of molecules and dust in the Universe, and T Leporis is no exception. It pulsates with a period of 380 days and loses the equivalent of the Earth's mass every year. Since the molecules and dust are formed in the layers of atmosphere surrounding the central star, astronomers would like to be able to see these layers. But this is no easy task, given that the stars themselves are so far away -- despite their huge intrinsic size, their apparent radius on the sky can be just half a millionth that of the Sun. "T Leporis looks so small from the Earth that only an interferometric facility, such as the VLTI at Paranal, can take an image of it. VLTI can resolve stars 15 times smaller than those resolved by the Hubble Space Telescope," says Le Bouquin. To create this image with the VLTI astronomers had to observe the star for several consecutive nights, using all the four movable 1.8-metre VLT Auxiliary Telescopes (ATs). The ATs were combined in different groups of three, and were also moved to different positions, creating more new interferometric configurations, so that astronomers could emulate a virtual telescope

Multi scale detail-preserving denoising method of infrared image via relative total variation  

NASA Astrophysics Data System (ADS)

How to remove the noise in infrared image effectively with detail preserving is a significant but difficult problem in infrared image processing. Various methods have been proposed to obtain good results. However, these algorithms usually cannot distinguish noise and detail efficiently, which leads to smoothing some details in infrared images. Recently a novel local measure called relative total variation (RTV) is proposed to accomplish effective texture removal. RTV measure is combined with a general windowed total variation measure and a novel inherent variation measure to smooth the image texture effectively while preserving the main structure. In this paper, using detail preserving smoothing method via RTV, a multi scale denoising algorithm for infrared image is proposed. Firstly, the infrared image is decomposed into several scales by non-subsampled Contourlet transform (NSCT). NSCT decomposition does not do any down sampling or up sampling, thus the results are not band limited. Secondly?the algorithm applies RTV based detail preserving denoising method for each decomposed layers. Different smoothing parameters are respectively used to adjust the denoising levels in different scales. Finally, various synthetic weights are utilized to different layers to reconstruct the final infrared denosing results. Compared with other infrared denoising approaches, the quantitative comparisons demonstrate that the proposed method could well suppress the noise of infrared image while preserving the edge details effectively. Both visual quality and objective measure results show that this method is efficient and has a good application in infrared image denoising.

Research of detecting details and features of infrared polarization imaging experiment  

NASA Astrophysics Data System (ADS)

Along with modern infrared camouflage technique developed, it is hard to distinguish target and background by using traditional infrared intensity imaging in general because infrared feature of target and background are tending to consistent. To address this issue, a thought that utilizes infrared polarization imaging technique to detect target is proposed in this paper based on analyzing of the principle of infrared polarization imaging. The experiments are carried out for detecting of infrared low-contrast target imaging. Comparing with the infrared intensity images, the average gradient of the infrared polarization image has been improved 155% and the contrast of target and background has been improved 120% in infrared polarization images. The effective experimental data and imaging law between infrared polarization images and infrared intensity images are obtained that, the technology of infrared polarization imaging can detect details of infrared target more clearly than the infrared intensity imaging, and it can obviously increase the contrast between target and background. Therefore, it is more helpful to detecting details and features of target.

A robust detail preserving anisotropic diffusion for speckle reduction in ultrasound images  

PubMed Central

Background Speckles in ultrasound imaging affect image quality and can make the post-processing difficult. Speckle reduction technologies have been employed for removing speckles for some time. One of the effective speckle reduction technologies is anisotropic diffusion. Anisotropic diffusion technology can remove the speckles effectively while preserving the edges of the image and thus has drawn great attention from image processing scientists. However, the proposed methods in the past have different disadvantages, such as being sensitive to the number of iterations or low capability of preserving the details of the ultrasound images. Thus a detail preserved anisotropic diffusion speckle reduction with less sensitive to the number of iterations is needed. This paper aims to develop this kind of technologies. Results In this paper, we propose a robust detail preserving anisotropic diffusion filter (RDPAD) for speckle reduction. In order to get robust diffusion, the proposed method integrates Tukey error norm function into the detail preserving anisotropic diffusion filter (DPAD) developed recently. The proposed method could prohibit over-diffusion and thus is less sensitive to the number of iterations Conclusions The proposed anisotropic diffusion can preserve the important structure information of the original image while reducing speckles. It is also less sensitive to the number of iterations. Experimental results on real ultrasound images show the effectiveness of the proposed anisotropic diffusion filter.

Placing Neuroanatomical Models of Executive Function in a Developmental Context Imaging and Imaging-Genetic Strategies  

PubMed Central

Children show gradual and protracted improvement in an array of behaviors involved in the conscious control of thought and emotion. Behavioral research has shown that these abilities, collectively referred to as executive functions (EF), can be dissociated into separable processes, such as inhibition and working memory. Furthermore, noninvasive neuroimaging shows that these component processes often rely on separable neural circuits involving areas of the frontal cortex and nuclei of the basal ganglia. As additional noninvasive methodologies become available, it is increasingly possible to continue to dissect and dissociate components of EF and also test predictions made by a number of theoretical neuroanatomical models. One method of late is genetics, which is noninvasive and readily used in concert with neuroimaging. The biological data obtained with neuroimaging and genetics is particularly able to inform neuroanatomical models that link specific brain systems with higher more abstract process models derived from purely behavioral work. As much progress in this area continues to occur, we seek to evaluate the age dependency and manner in which certain aspects of EF and certain anatomical circuits show changes and interactions as children develop. Some examples are taken from research on children with the developmental disability attention deficit hyperactivity disorder. A review of selected developmental research shows that current cognitive and neuroanatomical models of EF offer a great many system- and synaptic-level hypotheses that can be tested using imaging and imaging genetics in longitudinal and cross-sectional study designs. Here, we focus on age-related changes in inhibition and working memory.

A parameterization for land-atmosphere-cloud-exchange (PLACE): Documentation and testing of a detailed process model of the partly cloudy boundary layer over heterogeneous land  

SciTech Connect

This paper presents a general description of, and demonstrates the capabilities of, the Parameterization for Land-Atmosphere-Cloud Exchange (PLACE). The PLACE model is a detailed process model of the partly cloudy atmospheric boundary layer and underlying heterogeneous land surfaces. In its development, particular attention has been given to three of the model`s subprocesses: the prediction of boundary layer cloud amount, the treatment of surface and soil subgrid heterogeneity, and the liquid water budget. The model includes a three-parameter nonprecipitating cumulus model that feeds back to the surface and boundary layer though radiative effects. Surface heterogeneity in the PLACE model is treated both statistically and by resolving explicit subgrid patches. The model maintains a vertical column of liquid water that is divided into seven reservoirs, from the surface interception store down to bedrock. Five single-day demonstration cases are presented, in which the PLACE model was initialized, run, and compared to field observations from four diverse sites. The model is shown to predict cloud amount well in these cases while predicting the surface fluxes with similar accuracy. A slight tendency to underpredict boundary layer depth is noted in all cases. Sensitivity tests were also run using anemometer-level forcing provided by the Project for Inter-comparison of Land-surface Parameterization Schemes (PILPS). The purpose is to demonstrate the relative impact of heterogeneity of surface parameters on the predicted annual mean surface fluxes. Significant sensitivity to subgrid variability of certain parameters is demonstrated, particularly to parameters related to soil moisture. A major result is that the PLACE-computed impact of total (homogeneous) deforestation of a rain forest is comparable in magnitude to the effect of imposing heterogeneity of certain surface variables. 58 refs., 6 figs., 1 tab.

A perceptual evaluation of JPEG 2000 image compression for digital mammography: contrast-detail characteristics.  

PubMed

In this investigation the effect of JPEG 2000 compression on the contrast-detail (CD) characteristics of digital mammography images was studied using an alternative forced choice (AFC) technique. Images of a contrast-detail phantom, acquired using a clinical full-field digital mammography system, were compressed using a commercially available software product (JPEG 2000). Data compression was achieved at ratios of 1:1, 10:1, 20:1, and 30:1 and the images were reviewed by seven observers on a high-resolution display. Psychophysical detection characteristics were first computed by fitting perception data using a maximum-likelihood technique from which CD curves were derived at 50%, 62.5%, and 75% threshold levels. Statistical analysis indicated no significant difference in the perception of mean disk thickness up to 20:1 compression except for disk diameter of 1 mm. All other compression combinations exhibited significant degradation in CD characteristics. PMID:15255520

Segmentation and surface reconstruction of the detailed ear structures, identified in sectioned images.  

PubMed

The structure of the ear, which intervenes between gross anatomy and histology in size, can be best understood by means of three-dimensional (3D) surface models on a computer. Furthermore, surface models are the source of interactive simulation for clinical trials, such as tympanoplasty. The objective of this research was to elaborate the surface models of detailed ear structures, which contribute to learning anatomy or the practice of otology. We produced sectioned images of a cadaver head (pixel size, 0.1 mm; 48-bit color). In the sectioned images, the external, middle, and internal ear structures and other related components were delineated on Photoshop to acquire segmented images at 0.5-mm intervals. Segmented images of each structure were stacked, and the surface was reconstructed to generate a 3D-surface model on commercial software. Thirty surface models showed fine ear topographic anatomy (e.g., semicircular ducts), as expected. Herein, we present the corresponding sectioned images, segmented images, and surface models of ear structures that will be released together. It is hoped that these image data will stimulate the development of medical simulations. The efficient technique of segmentation and surface reconstruction enables the manufacture of surface models from other serial images (e.g., CTs and MRIs). PMID:21365774

On Detailed Contrast of Biomedical Object in X-ray Dark-Field Imaging  

SciTech Connect

Over the past 10 years, refraction-based X-ray imaging has been studied together with a perspective view to clinical application. X-ray Dark-Field Imaging that utilizes a Laue geometry analyzer has recently been proposed and has the proven ability to depict articular cartilage in an intact human finger. In the current study, we researched detailed image contrast using X-ray Dark-Field Imaging by observing the edge contrast of an acrylic rod as a simple case, and found differences in image contrast between the right and left edges of the rod. This effect could cause undesirable contrast in the thin articular cartilage on the head of the phalanx. To avoid overlapping with this contrast at the articular cartilage, which would lead to a wrong diagnosis, we suggest that a joint surface on which articular cartilage is located should be aligned in the same sense as the scattering vector of the Laue case analyzer crystal. Defects of articular cartilage were successfully detected under this condition. When utilized under appropriate imaging conditions, X-ray Dark-Field Imaging will be a powerful tool for the diagnosis of arthropathy, as minute changes in articular cartilage may be early-stage features of this disease.

Effect of background detail on CD curve slope in CT head images  

NASA Astrophysics Data System (ADS)

The purpose of this work was to analyze the influence of background structure on the slopes of contrast-detail (CD) curves in CT images acquired in uniform phantoms, anthropomorphic head phantoms, and in clinical head CT images. Alternative forced-choice (AFC) studies were performed using CT images acquired in uniform (water) phantoms, anthropomorphic (RANDO and ATOM) phantoms, and clinical head scans. The AFC experiments measure the lesion contrast (I92%) that corresponds to 92% detection efficiency. The AFC experimental results were plotted as a function of lesion size to produce CD curves, and the slopes of the curves determined when plotted on log-log axes. The Rose model of detection predicts a slope of -1.0 for disk lesions in uniform backgrounds and white noise. CD curve slopes showed a progression that depends on the complexity of the background structure in the CT images. For uniform water phantom images, the slope averaged -0.9, which is close to that predicted by the Rose model. For the anthropomorphic phantoms, the slope averaged -0.56, and for the patient scans the average slope was -0.20. The slope of CD curves depends strongly on the background structure of the images in which the lesions are embedded, with increased background structure leading to decreased CD curve slopes. The Rose model reasonably predicts the slopes for CD curves acquired in uniform phantoms, but is a poor predictor of slopes in clinical head images.

A novel material detection algorithm based on 2D GMM-based power density function and image detail addition scheme in dual energy X-ray images.  

PubMed

Material detection is a vital need in dual energy X-ray luggage inspection systems at security of airport and strategic places. In this paper, a novel material detection algorithm based on statistical trainable models using 2-Dimensional power density function (PDF) of three material categories in dual energy X-ray images is proposed. In this algorithm, the PDF of each material category as a statistical model is estimated from transmission measurement values of low and high energy X-ray images by Gaussian Mixture Models (GMM). Material label of each pixel of object is determined based on dependency probability of its transmission measurement values in the low and high energy to PDF of three material categories (metallic, organic and mixed materials). The performance of material detection algorithm is improved by a maximum voting scheme in a neighborhood of image as a post-processing stage. Using two background removing and denoising stages, high and low energy X-ray images are enhanced as a pre-processing procedure. For improving the discrimination capability of the proposed material detection algorithm, the details of the low and high energy X-ray images are added to constructed color image which includes three colors (orange, blue and green) for representing the organic, metallic and mixed materials. The proposed algorithm is evaluated on real images that had been captured from a commercial dual energy X-ray luggage inspection system. The obtained results show that the proposed algorithm is effective and operative in detection of the metallic, organic and mixed materials with acceptable accuracy. PMID:22635176

Analysis of VIS-LWIR hyperspectral image data for detailed geologic mapping  

NASA Astrophysics Data System (ADS)

Research is being conducted into the usefulness of hyperspectral data for detailed geologic mapping applications. The data being analyzed were collected by the HYDICE (VIS-SWIR) and SEBASS (LWIR) airborne imaging spectrometers. Hyperspectral data provides a means of identifying surface minerology, which indicates lithology. In addition, because the data are collected in image format, photo-geologic observations can be made, such as the presence and orientation of stratification and faulting. The results of hyperspectral-based geologic mapping are summarized for an area of volcanic and sedimentary rocks in southwest Nevada. Analysis of the data revealed 11 mineral endmembers representing eight lithologic units. The hyperspectral-derived maps were directly compared to the best ground-based geologic maps available. Results indicate the ability to produce general geologic maps at scales better than 1:24,000 using 1-meter resolution airborne spectroscopy. Also, a more thorough mapping was achieved because of the increased compositional information gained by using both eht SWIR and LWIR.

In this case the size of the image does not match the size of the object contrary to the edge detection technique. Moreover, the structure of the central fringes of the image is universal, i.e. it is independent of the object cross-section structure. Therefore, these images have no detailed information on the object.

Small animal SPECT and its place in the matrix of molecular imaging technologies.  

PubMed

Molecular imaging refers to the use of non-invasive imaging techniques to detect signals that originate from molecules, often in the form of an injected tracer, and observe their interaction with a specific cellular target in vivo. Differences in the underlying physical principles of these measurement techniques determine the sensitivity, specificity and length of possible observation of the signal, characteristics that have to be traded off according to the biological question under study. Here, we describe the specific characteristics of single photon emission computed tomography (SPECT) relative to other molecular imaging technologies. SPECT is based on the tracer principle and external radiation detection. It is capable of measuring the biodistribution of minute (<10(-10) molar) concentrations of radio-labelled biomolecules in vivo with sub-millimetre resolution and quantifying the molecular kinetic processes in which they participate. Like some other imaging techniques, SPECT was originally developed for human use and was subsequently adapted for imaging small laboratory animals at high spatial resolution for basic and translational research. Its unique capabilities include (i) the ability to image endogenous ligands such as peptides and antibodies due to the relative ease of labelling these molecules with technetium or iodine, (ii) the ability to measure relatively slow kinetic processes (compared with positron emission tomography, for example) due to the long half-life of the commonly used isotopes and (iii) the ability to probe two or more molecular pathways simultaneously by detecting isotopes with different emission energies. In this paper, we review the technology developments and design tradeoffs that led to the current state-of-the-art in SPECT small animal scanning and describe the position SPECT occupies within the matrix of molecular imaging technologies.

Novel cryo-imaging of the glioma tumor microenvironment reveals migration and dispersal pathways in vivid three-dimensional detail

Traditional methods of imaging cell migration in the tumor microenvironment include serial sections of xenografts and standard histological stains. Current molecular imaging techniques suffer from low resolution and difficulty in imaging through the skull. Here we show how computer algorithms can be used to reconstruct images from tissue sections obtained from mouse xenograft models of human glioma and can be rendered into 3-D images offering exquisite anatomic detail of tumor cell dispersal. Our findings identify human LN-229 and rodent CNS-1 glioma cells as valid systems to study the highly dispersive nature of glioma tumor cells along blood vessels and white matter tracts in vivo. This novel cryo-imaging technique provides a valuable tool to evaluate therapeutic interventions targeted at limiting tumor cell invasion and dispersal.

Between a rock and a hard place: clinical and imaging features of vascular compression syndromes.  

PubMed

Vascular compression syndromes are caused by the entrapment of vessels between rigid or semirigid surfaces in a confined anatomic space. Chronic entrapment may lead to arterial ischemia and embolism, venous stasis and thrombosis, and hematuria. These syndromes are usually seen in otherwise healthy young patients, among whom underdiagnosis is common. Most occurrences of vascular compression are associated with an underlying anatomic abnormality. In a small percentage of cases, other contributing factors, including repetitive microtrauma, may cause pathologic changes leading to the onset of pain and other symptoms of vascular and neural compression. Hence, the diagnosis must be based on both clinical and radiologic findings. Because some cases of vascular entrapment become symptomatic only when specific physical maneuvers are performed, dynamic diagnostic imaging methods are especially useful. Digital subtraction angiography has been the mainstay of imaging-based diagnosis for most vascular compression syndromes, but other methods (eg, color Doppler ultrasonography, computed tomographic angiography, and magnetic resonance angiography) are used with increasing frequency for initial diagnostic evaluation. Because vascular compression syndromes are caused by the external compression of vessels, endoluminal treatment alone is rarely adequate and surgical decompression is likely to be required for optimal and durable clinical benefit.

Enceladus Close Up: New Details Recovered from Cassini ISS Boresight-Drag Images  

NASA Astrophysics Data System (ADS)

Among the many Cassini ISS (Imaging Science Subsystem) images of Enceladus are a few severely-underexposed, motion-blurred images that were acquired on “boresight-drag” events on the closest flybys. During boresight-drags, ISS is statically aimed at a point that intercepts the predicted path of Enceladus’ across the sky. The ISS Narrow angle (NAC) and Wide Angle (WAC) cameras are repeatedly triggered together in hope of serendipitously capturing a close-up “BOTSIM” image-pair of the body as it passes. Because the events are so fast, the surface footprints and lighting geometry cannot be predicted in advance - a cascade of images are just quickly shuttered at the minimum 5 msec exposure. On each of four boresight-drags, surface images were captured. However, the two most recent (image-pair W/N1669812043 in November 2010 and W/N1713106405 in April 2012, respectively) were poorly illuminated -- three of four images only in Saturnshine. Despite their poor signal quality, they are rare images of Enceladus’ surface obtained with spatial resolutions better than a few meters/pixel. Careful use of Fourier filtering and spatial reconstruction techniques was needed to eliminate image noise and residual electronic banding that was not removed during routine radiometric calibration of the images. Fourier motion debluring techniques were then applied to correct for significant motion smear. Images W/N1669812043 (55.1°N, 20.2°W) are in old cratered terrain, inside a prominent 23 km sized impact crater along the rise of its updomed floor. They show a system of parallel ~250m wide mesas trending around the dome’s circumference. Smooth detritus inundates mesas and valleys near the dome summit and the mesa surfaces are otherwise mantled with regolith that is finely cratered down to the ~2 m/pixel NAC resolution limit. W/N1713106405 (66.9°S, 29.5°W) show the chaotically fractured margin of the active South Polar Terrain - an area divided by parallel ridges and troughs with relatively smooth flanks and valley floors. Quasi-linear arrangements of ice-blocks, each block tens of meters or smaller, are found mostly near ridge-tops.

Whole-body pregnant woman modeling by digital geometry processing with detailed uterofetal unit based on medical images.  

PubMed

Anatomical models of pregnant women are used in several applications, such as numerical dosimetry, to assess the potential effects of electromagnetic fields on biological tissues, or medical simulation. Recent advances in medical imaging have enabled the generation of realistic and detailed models of human beings. The construction of pregnant woman models remains a complex task, since it is not possible to acquire whole-body images. Only few models have been developed up to now, and they all present some limitations regarding the representation of anatomical variability of the fetus shape and position over the entire gestation. This paper describes a complete methodology that intends to automate each step of the construction of pregnant women models. The proposed approach relies on the segmentation of 3-D ultrasonic and 3-D magnetic resonance imaging (MRI) data, and on dedicated computer graphics tools. The lack of complete anatomical information for the mother in image data is compensated, in an original way, by merging the available information with a synthetic woman model, deformed to match the image-based information. A set of models anatomically validated by clinical experts is presented. They include detailed information on uterofetal units and cover different gestational stages with various fetal positions.

Image quality assessment in digital mammography: part II. NPWE as a validated alternative for contrast detail analysis  

NASA Astrophysics Data System (ADS)

Assessment of image quality for digital x-ray mammography systems used in European screening programs relies mainly on contrast-detail CDMAM phantom scoring and requires the acquisition and analysis of many images in order to reduce variability in threshold detectability. Part II of this study proposes an alternative method based on the detectability index (d') calculated for a non-prewhitened model observer with an eye filter (NPWE). The detectability index was calculated from the normalized noise power spectrum and image contrast, both measured from an image of a 5 cm poly(methyl methacrylate) phantom containing a 0.2 mm thick aluminium square, and the pre-sampling modulation transfer function. This was performed as a function of air kerma at the detector for 11 different digital mammography systems. These calculated d' values were compared against threshold gold thickness (T) results measured with the CDMAM test object and against derived theoretical relationships. A simple relationship was found between T and d', as a function of detector air kerma; a linear relationship was found between d' and contrast-to-noise ratio. The values of threshold thickness used to specify acceptable performance in the European Guidelines for 0.10 and 0.25 mm diameter discs were equivalent to threshold calculated detectability indices of 1.05 and 6.30, respectively. The NPWE method is a validated alternative to CDMAM scoring for use in the image quality specification, quality control and optimization of digital x-ray systems for screening mammography.

Threshold contrast detail detectability measurement of the fluoroscopic image quality of a dynamic solid-state digital x-ray image detector.  

PubMed

Solid-state digital x-ray imaging detectors of flat-panel construction will play an increasingly important role in future medical imaging facilities. Solid-state detectors that will support both dynamic (including fluoroscopic) and radiographic image recording are under active development. The image quality of an experimental solid-state digital x-ray image detector operating in a continuous fluoroscopy mode has been investigated. The threshold contrast detail detectability (TCDD) technique was used to compare the fluoroscopic imaging performance of an experimental dynamic solid-state digital x-ray image detector with that of a reference image intensifier television (IITV) fluoroscopy system. The reference system incorporated Plumbicon TV. Results were presented as a threshold detection index, or H(T)(A), curves. Measurements were made over a range of mean entrance air kerma (EAK) rates typically used in conventional IITV fluoroscopy. At the upper and mid EAK rate range (440 and 220 nGy/s) the solid-state detector outperformed the reference IITV fluoroscopy system as measured by TCDD performance. At the lowest measured EAK rate (104 nGy/s), the solid-state detector produces slightly inferior TCDD performance compared with the reference system. Although not statistically significant at this EAK rate, the difference will increase as EAK is lowered further. Overall the TCDD results and early clinical experiences support the proposition that a current design of dynamic solid-state detector produces image quality competitive with that of modern IITV fluoroscopy systems. These findings encourage the development of compact and versatile universal x-ray imaging systems based upon solid-state detector technology to support R & F and vascular/interventional applications.

Detailed interrogation of trypanosome cell biology via differential organelle staining and automated image analysis  

PubMed Central

Background Many trypanosomatid protozoa are important human or animal pathogens. The well defined morphology and precisely choreographed division of trypanosomatid cells makes morphological analysis a powerful tool for analyzing the effect of mutations, chemical insults and changes between lifecycle stages. High-throughput image analysis of micrographs has the potential to accelerate collection of quantitative morphological data. Trypanosomatid cells have two large DNA-containing organelles, the kinetoplast (mitochondrial DNA) and nucleus, which provide useful markers for morphometric analysis; however they need to be accurately identified and often lie in close proximity. This presents a technical challenge. Accurate identification and quantitation of the DNA content of these organelles is a central requirement of any automated analysis method. Results We have developed a technique based on double staining of the DNA with a minor groove binding (4'', 6-diamidino-2-phenylindole (DAPI)) and a base pair intercalating (propidium iodide (PI) or SYBR green) fluorescent stain and color deconvolution. This allows the identification of kinetoplast and nuclear DNA in the micrograph based on whether the organelle has DNA with a more A-T or G-C rich composition. Following unambiguous identification of the kinetoplasts and nuclei the resulting images are amenable to quantitative automated analysis of kinetoplast and nucleus number and DNA content. On this foundation we have developed a demonstrative analysis tool capable of measuring kinetoplast and nucleus DNA content, size and position and cell body shape, length and width automatically. Conclusions Our approach to DNA staining and automated quantitative analysis of trypanosomatid morphology accelerated analysis of trypanosomatid protozoa. We have validated this approach using Leishmania mexicana, Crithidia fasciculata and wild-type and mutant Trypanosoma brucei. Automated analysis of T. brucei morphology was of comparable quality to manual analysis while being faster and less susceptible to experimentalist bias. The complete data set from each cell and all analysis parameters used can be recorded ensuring repeatability and allowing complete data archiving and reanalysis.

A new automated assessment method for contrast-detail images by applying support vector machine and its robustness to nonlinear image processing.  

PubMed

The automated contrast-detail (C-D) analysis methods developed so-far cannot be expected to work well on images processed with nonlinear methods, such as noise reduction methods. Therefore, we have devised a new automated C-D analysis method by applying support vector machine (SVM), and tested for its robustness to nonlinear image processing. We acquired the CDRAD (a commercially available C-D test object) images at a tube voltage of 120 kV and a milliampere-second product (mAs) of 0.5-5.0. A partial diffusion equation based technique was used as noise reduction method. Three radiologists and three university students participated in the observer performance study. The training data for our SVM method was the classification data scored by the one radiologist for the CDRAD images acquired at 1.6 and 3.2 mAs and their noise-reduced images. We also compared the performance of our SVM method with the CDRAD Analyser algorithm. The mean C-D diagrams (that is a plot of the mean of the smallest visible hole diameter vs. hole depth) obtained from our devised SVM method agreed well with the ones averaged across the six human observers for both original and noise-reduced CDRAD images, whereas the mean C-D diagrams from the CDRAD Analyser algorithm disagreed with the ones from the human observers for both original and noise-reduced CDRAD images. In conclusion, our proposed SVM method for C-D analysis will work well for the images processed with the non-linear noise reduction method as well as for the original radiographic images.

Combining Seismic Arrays to Image Detailed Rupture Properties of Large Earthquakes: Evidence for Frequent Triggering of Multiple Faults  

NASA Astrophysics Data System (ADS)

Imaging detailed rupture characteristics using the back-projection method, which time-reverses waveforms to their source, has become feasible in recent years due to the availability of data from large aperture arrays with dense station coverage. In contrast to conventional techniques, this method can quickly and indiscriminately provide the spatio-temporal details of rupture propagation. Though many studies have utilized the back-projection method with a single regional array, the limited azimuthal coverage often leads to skewed resolution. In this study, we enhance the imaging power by combining data from two arrays, i.e., the Transportable Array (TA) in the United States and the High Sensitivity Seismographic Network (Hi-net) in Japan. This approach suppresses artifacts and achieves good lateral resolution by improving distance and azimuthal coverage while maintaining waveform coherence. We investigate four large events using this method: the August 15, 2007 Pisco, Peru earthquake, the September 12, 2007 Southern Sumatra earthquake, the September 29, 2009 Samoa Islands earthquake, and the February 27, 2010 Maule, Chile earthquake. In every case, except the Samoa Islands event, the distance of one of the arrays from the epicenter requires us to use the direct P wave and core phases in the back-projection. One of the common features of the rupture characteristics obtained from the back-projection analysis is spatio-temporal rupture discontinuities, or discrete subevents. Both the size of the gaps and the timing between subevents suggest that multiple segments are involved during giant earthquakes, and that they trigger slip on other faults. For example, the 2009 Samoa Islands event began with a rupture propagating north for about 15 seconds followed by a much larger rupture that originated 30 km northwest of the terminus of the first event and propagated back toward the southeast. The involvement of multiple rupture segments with different slip characteristics suggest that large earthquakes are more complex compared to smaller events.

Detailed Decomposition of Galaxy Images II: Fitting Spiral Arms, Bars, and Non-axisymmetric Structures in GALFIT 3.0  

NASA Astrophysics Data System (ADS)

The technique of fitting galaxy light profiles with analytic functions (e.g. de Vaucouleurs, exponential), also known as parametric fitting, has been a useful tool for studying galaxy structure and evolution. It is often used to quantify global properties of galaxies such as luminosity, size, ellipticity, and profile shape in a self-consistent manner. It also allows one to deblend multiple components of a galaxy, e.g. bulge/disk/bar/AGN, or to separate overlapping galaxies in a rigorous and robust way. However, the traditional method of fitting galaxies relies on using ellipsoid models, which is sometimes criticized to argue in favor of non-parametric techniques. In this study, we show that two dimensional image fitting is not fundamentally restricted to using axisymmetric ellipsoid shapes. By breaking from axisymmetry parametrically through the use of Fourier modes, one can better quantify the degree of galaxy irregularity in an intuitive and well-motivated manner. We also introduce a technique that allows one to fit spiral structures in late-type galaxies through the use of coordinate rotation. By comparing with more realistic models now possible, we find that the traditional use of simple ellipsoid models is robust even on irregular and spiral galaxies, because single component fits are by nature large scale averages. However, when it comes to quantifying sub-components of a galaxy, sometimes it is necessary to model structures in detail, such as when performing bulge-to-disk decomposition of galaxies with strong spiral arms, or quantifying the symmetry due to bright (e.g. bulge) and faint (e.g. disk) galaxy sub-components separately. These new techniques are implemented in GALFIT 3.0 (http://www.ociw.edu/ peng/work/galfit/galfit.html ).

Flooded areas assessment by integrating hydraulic flood analysis to the detailed flood maps generated with a multi-temporal image segmentation approach using Cosmo-Skymed  

NASA Astrophysics Data System (ADS)

The support of Earth Observation Systems to flood monitoring and damage assessment has been evaluated by integrating skills and knowledge of hydrologists and experts on image processing. Detailed flood maps are generated from the analysis of images pairs acquired by Cosmo-Skymed on the same area at different times. The adopted methodology applies image pre-processing and segmentation techniques with a multi-temporal approach. After noise reduction by despeckling, the user manually localizes few water points in one image. From selected points, segmentation distinguishes the classes of flood, permanent-water and no-change areas. Then, an anisotropic scanning analyzes the images to define its content. The resulting connected regions are converted into vectors to be entered as constraint for a Physically based 2-D hydraulic flood model. The model recursively varies the unknown boundary conditions to match at best the areas extracted from Cosmo-Skymed. The product is a hydraulic consistent report of the flooded area including information on water depth and velocities. By combining these information with vulnerability maps, extracted from optical satellite images with a supervised approach, an estimation of the damage is provided. The reported results refer to the monitoring of the flood event occurred in the Scutari Lake area (Albania, January 2010).

Crosswell Seismic Amplitude-Versus-Offset for Detailed Imaging of Facies and Fluid Distribution within Carbonate Oil Reservoirs  

SciTech Connect

Crosswell seismic surveys were conducted at two fields in northern Michigan. One of these, Springdale, included two monitor wells that are located external to the reef, and the other, Coldspring, employed two production wells within the reef. The Springdale wells extended to much greater depths than the reef, and imaging was conducted from above and from beneath the reef. The resulting seismic images provide the best views of pinnacle Niagaran reefs obtained to date. The tops of the reservoirs can be clearly distinguished, and their lateral extent or dipping edges can be observed along the profile. Reflecting events internal to the reef are evident; some of them are fairly continuous across the reef and others are discontinuous. Inversion of the seismic data indicates which events represent zones of higher porosity and which are lower porosity or even anhydrite plugged. The full stacked image includes angles that are beyond critical for many of the interfaces, and some reflections are visible only for a small range of angles, presumably near their critical angle. Stacking these angles in provides an opportunity for these events to be seen on the stacked image, where otherwise they would have been unrecognized. For inversion, however, the complexity associated with phase changes beyond critical can lead to poor results, and elastic inversion of partial angle stacks may be best conducted with restrictions to angles less than critical. Strong apparent attenuation of signals occurs when seismic ray paths pass through the upper part of the Springdale reservoir; this may be due to intrinsic attenuation and/or scattering of events due to the locally strongly varying gas saturation and extremely low fluid pressures. Signal-to-noise limitations become evident far from the source well in the Coldspring study, probably because the raw data were strongly affected by tube-wave noise generated by flow through the perforation of the receiver well. The seismic images obtained, and interpretations of them, as assisted by Amplitude-versus-Angle studies and accompanying inversion, provide additional insight into the internal geometry of these two reefs and provide data that should be useful for reservoir management.

Detailed in situ laser calibration of the infrared imaging video bolometer for the JT-60U tokamak  

SciTech Connect

The infrared imaging video bolometer (IRVB) in JT-60U includes a single graphite-coated gold foil with an effective area of 9x7 cm{sup 2} and a thickness of 2.5 {mu}m. The thermal images of the foil resulting from the plasma radiation are provided by an IR camera. The calibration technique of the IRVB gives confidence in the absolute levels of the measured values of the plasma radiation. The in situ calibration is carried out in order to obtain local foil properties such as the thermal diffusivity {kappa} and the product of the thermal conductivity k and the thickness t{sub f} of the foil. These quantities are necessary for solving the two-dimensional heat diffusion equation of the foil which is used in the experiments. These parameters are determined by comparing the measured temperature profiles (for kt{sub f}) and their decays (for {kappa}) with the corresponding results of a finite element model using the measured HeNe laser power profile as a known radiation power source. The infrared camera (Indigo/Omega) is calibrated by fitting the temperature rise of a heated plate to the resulting camera data using the Stefan-Boltzmann law.

A before and after study of the impact of academic detailing on the use of diagnostic imaging for shoulder complaints in general practice  

PubMed Central

Background The aim of this study was to assess the impact that Academic Detailing (AD) had on General Practitioners' use of diagnostic imaging for shoulder complaints in general practice and their knowledge and confidence to manage shoulder pain. Methods One-to-one Academic Detailing (AD) for management of shoulder pain was delivered to 87 General Practitioners (GPs) in metropolitan Adelaide, South Australia, together with locally developed clinical guidelines and a video/DVD on how to examine the shoulder. Three months after the initial AD a further small group or an individual follow up session was offered. A 10-item questionnaire to assess knowledge about the shoulders was administered before, immediately after, and 3 months after AD, together with questions to assess confidence to manage shoulder complaints. The number of requests for plain film (X-ray) and ultrasound (US) imaging of the shoulder was obtained for the intervention group as well as a random comparison group of 90 GP's from the same two Divisions. The change in the rate of requests was assessed using a log Poisson GEE with adjustment for clustering at the practice level. A linear mixed effects model was used to analyse changes in knowledge. Results In an average week 54% of GPs reported seeing fewer than 6 patients with shoulder problems. Mean (SD) GP knowledge score before, immediately after and 3-months after AD, was 6.2/10 (1.5); 8.6/10 (0.96) and; 7.2/10 (1.5) respectively (p < 0.0001). Three months after AD, GPs reported feeling able to take a more meaningful history, more confident managing shoulder pain, and felt their management of shoulder pain had improved. Requests for ultrasound imaging were approximately 43.8% higher in the period 2 years before detailing compared to six months after detailing (p < 0.0001), but an upward trend toward baseline was observed in the period 6 months to 1 year after AD. There was no statistically significant change in the rate of requests from before to after AD for plain-radiographs (p = 0.11). No significant changes in the rate of requests over time were observed in the control groups. Conclusion These results provide evidence that AD together with education materials and guidelines can improve GPs' knowledge and confidence to manage shoulder problems and reduce the use of imaging, at least in the short term.

Label-free and highly sensitive optical imaging of detailed microcirculation within meninges and cortex in mice with the cranium left intact  

PubMed Central

We demonstrate for the first time that the detailed blood flow distribution within intracranial dura mater and cortex can be visualized by an ultrahigh sensitive optical microangiography (UHS-OMAG). The study uses an UHS-OMAG system operating at 1310 nm with an imaging speed at 150 frames per second that requires ?10 s to complete one 3-D scan of ?2.5×2.5 mm2. The system is sensitive to blood flow with a velocity ranging from ?4 ?m?s to ?23 mm?s. We show superior performance of UHS-OMAG in providing functional images of capillary level microcirculation within meninges in mice with the cranium left intact, the results of which correlate well with the standard dural histopathology.

Image quality performance of liquid crystal display systems: influence of display resolution, magnification and window settings on contrast-detail detection.  

PubMed

The aim of this study was to investigate the combined effects of liquid crystal display (LCD) resolution, image magnification and window/level adjustment on the low-contrast performance in soft-copy image interpretation in digital radiography and digital mammography. In addition, the effect of a new LCD noise reduction mechanism on the low-contrast detectability was studied. Digital radiographs and mammograms of two dedicated contrast-detail phantoms (CDRAD 2.0 and CDMAM 3.4) were scored on five LCD devices with varying resolutions (1-3- and 5-megapixel) and one dedicated 5-megapixel cathode ray tube monitor. Two 5-megapixel LCDs were included. The first one was a standard 5-megapixel LCD and the second had a new (Per Pixel Uniformity) noise reduction mechanism. A multi-variate analysis of variance revealed a significant influence of LCD resolution, image magnification and window/level adjustment on the image quality performance assessed with both the CDRAD 2.0 and the CDMAM 3.4 phantoms. The interactive adjustment of brightness and contrast of digital images did not affect the reading time, whereas magnification to full resolution resulted in a significantly slower soft-copy interpretation. For digital radiography applications, a 3-megapixel LCD is comparable with a 5-megapixel CRT monitor in terms of low-contrast performance as well as in reading time. The use of a 2-megapixel LCD is only warranted when radiographs are analysed in full resolution and when using the interactive window/level adjustment. In digital mammography, a 5-megapixel monitor should be the first choice. In addition, the new PPU noise reduction system in the 5-megapixel LCD devices provides significantly better results for mammography reading as compared to a standard 5-magapixel LCD or CRT. If a 3-megapixel LCD is used in mammography setting, a very time-consuming magnification of the digital mammograms would be necessary. PMID:16442770

Detailed modeling and laser-induced fluorescence imaging of nitric oxide in a NH(i)-seeded non-premixed methane/air flame  

SciTech Connect

In this paper we study the formation of NO in laminar, nitrogen diluted methane diffusion flames that are seeded with ammonia in the fuel stream. We have performed numerical simulations with detailed chemistry as well as laser-induced fluorescence imaging measurements for a range of ammonia injection rates. For comparison with the experimental data, synthetic LIF images are calculated based on the numerical data accounting for temperature and fluorescence quenching effects. We demonstrate good agreement between measurements and computations. The LIF corrections inferred from the simulation are then used to calculate absolute NO mole fractions from the measured signal.The NO formation in both doped and undoped flames occurs in the flame sheet. In the undoped flame, four different mechanisms including thermal and prompt NO appear to contribute to NO formation. As the NH3 seeding level increases, fuel-NO becomes the dominant mechanism and N2 shifts from being a net reactant to being a net product. Nitric oxide in the undoped flame as well as in the core region of the doped flames are underpredicted by the model; we attribute this mainly to inaccuracies in the NO recycling chemistry on the fuel-rich side of the flame sheet.

High Resolution Seismic Survey off the Pacific Shore of Costa Rica - Detailed Imaging of Deformational Patterns, Fluid Venting and Carbonate Mounds  

NASA Astrophysics Data System (ADS)

R/V METEOR Research Cruise M54/1 in summer 2002 from Balboa (Panama) to Caldera (Costa Rica) aimed at imaging the near sea floor sedimentary structures of both the continental and oceanic plates of the Costa Rican Subduction Zone with the high resolution seismic method. The cruise evolved from a cooperation of the Marine Seismics Group of the University of Bremen with the DFG funded Special Research Project 574 - Fluids and Volatiles in Subduction Zones - and is intended to supplement the marine geophysical, geological and geochemical as well as oceanographic data collected during R/V SONNE cruises in the area, as well as subsequent R/V METEOR cruises M54/2 and /3. The objectives of SFB 574 are the investigation of shallow and deep processes in subduction zones through near surface sampling of fluid vent sites and gas hydrate occurrences, as well as through detailed seismic and acoustic imaging of related structures. The main objectives of the cruise were to study 1) the volatile and material input into the sedimentary system on the oceanic plate, 2) the distribution of gas hydrates within the sediments, and 3) possible pathways and resulting structures of fluid/gas escape. Several working areas were selected, which had been identified as highly fractured sediment packages above subducting seamounts (Jaco Scar, Parrita Scar, Rio Bongo, Hongo area), areas of pronounced decollement reflection, major slump masses (Nicoya slide), regions of major fracturing of the oceanic crust, or carbonate mounds (Hongo area, Mound Culebra) during previous cruises. For calibration of seismic data, survey lines were also shot in the vicinity of ODP Leg 170 drill sites. Several seismic examples from various survey sites will be shown. Closely spaced profiles, allowing the acquisition of 3D and 2.5D seismic data in the Hongo area and near Mound Culebra, respectively, reveal the complex internal structure of fluid pathways, the distribution of gas hydrates, and the tectonic framework of small scale faulting and slumping. Multichannel seismic and digital sediment echosounder data were complemented by recordings from an ocean bottom hydrophone network, suitable for 3D tomography. Near Jaco and Parrita Scars, digital sediment echosounder and seismic data show pronounced lateral amplitude variations at the sea floor and in shallow sub-surface, which may indicate carbonate precipitation, shallow gas accumulation and gas hydrate occurrences associated with complex small scale faulting patterns.

Images of a place and vacation preferences: Implications of the 1989 surveys for assessing the economic impacts of a nuclear waste repository in Nevada  

SciTech Connect

In July, 1989 the authors produced a report titled Perceived Risk, Stigma, and Potential Economic Impacts of a High-Level Nuclear-Waste Repository in Nevada (Slovic et al., 1989). That report described a program of research designed to assess the potential impacts of a high-level nuclear waste repository at Yucca Mountain, Nevada upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. It was concluded that adverse economic impacts potentially may result from two related social processes. Specifically, the study by Slovic et al. employed analyses of imagery in order to overcome concerns about the validity of direct questions regarding the influence of a nuclear-waste repository at Yucca Mountain upon a person`s future behaviors. During the latter months of 1989, data were collected in three major telephone surveys, designed to achieve the following objectives: (1) to replicate the results from the Phoenix, Arizona, surveys using samples from other populations that contribute to tourism, migration, and development in Nevada; (2) to retest the original Phoenix respondents to determine the stability of their images across an 18-month time period and to determine whether their vacation choices subsequent to the first survey were predictable from the images they produced in that original survey; (3) to elicit additional word-association images for the stimulus underground nuclear waste repository in order to determine whether the extreme negative images generated by the Phoenix respondents would occur with other samples of respondents; and (4) to develop and test a new method for imagery elicitation, based upon a rating technique rather than on word associations. 2 refs., 8 figs., 13 tabs.

Detailed imager evaluation and unique applications of a new 20cmx25-cm size mercuric iodide thick film x-ray detector  

NASA Astrophysics Data System (ADS)

We previously reported on 2"x 2" and 4" x 4" size imagers, direct digital radiography X-ray detectors, based on photoconductive polycrystalline mercuric iodide deposited on a flat panel thin film transistor (TFT) array, as having great potential for use in medical imaging, NDE, and security applications. Recently we successfully upgraded our mercuric iodide deposition technique to 20 cm x 25 cm size, the size required in common NDE and security imaging applications. A TFT array with a pixel pitch of 127 microns was used for this imager. The mercuric iodide direct conversion layers were vacuum deposited onto TFT array by Physical Vapor Deposition (PVD). In addition to successful imager scale up, more sophisticated, non-TFT based detectors were developed in order to improve analysis methods of the mercuric iodide photoconductor. Measurements on mercuric iodide photoconductor were performed using a 36 x 6 electrode array on a 10cm x 10cm substrate (total of 216 measurement points). The array is formed by 36 palladium stripes on the glass substrate, upon which the mercuric iodide is deposited, and 6 palladium stripes that are deposited on top of the mercuric iodide layer. These two sets of electrodes are oriented at 90 degrees to each other to create the measurement matrix. These detectors were evaluated in radiographic mode, continuous fluoroscopic mode and pulsed fluoroscopic mode. Mercuric iodide coatings with thickness ranging between 140 microns and 300 microns were tested using beams with energies between 40 kVp and 100 kVp utilizing exposure ranges typical for both fluoroscopic and radiographic imaging. Diagnostic quality radiographic and fluroscopic images at up to 15 pulses per second were demonstrated. We evaluated the dark current, sensitivity and MTF characteristics. The MTF is determined primarily by the aperture and pitch of the TFT array with Nyquist frequency of ~3.93 mm-1 (127 micron pixel pitch). The MTF curve of a good quality HgI2 imager is very close to the theoretical sinc function. Image lag characteristics of mercuric iodide appear adequate for fluoroscopic rates.

Comparison of a-Si:H CsI flat-panel digital imaging systems with a CCD-based system, CR systems, and conventional screen-film systems: a contrast-detail phantom study  

NASA Astrophysics Data System (ADS)

Low-contrast detail detectability was evaluated and compared for a flat-panel digital chest system, a computed radiography (CR) system and a conventional screen/film (SF) system. Images of a contrast-detail phantom were acquired using these three systems under identical conditions. Additional images were acquired at varied exposures to study the potential for reduction of patient exposure using the flat-panel system. The results demonstrated that in chest imaging, the flat-panel system performed significantly better than the CR and the SF systems while the latter two performed about the same. Alternatively, an exposure reduction of at least 50% is possible if the same performance is maintained. For mammographic imaging, detectability for microcalcifications ((mu) Cs) was evaluated and compared for a flat-panel based full-field digital mammography (FFDM) system, a charge-coupled device (CCD) -based small-field system, a high resolution CR system and a conventional SF system. Images of simulated calcifications of three size ranges were acquired and evaluated by readers for detectability of the (mu) Cs. A Receiver Operating Characteristics (ROC) analysis was also performed to compare the overall detection accuracy for these four mammographic imaging systems. Our results show that in both the detectability analysis and the ROC analysis, the flat-panel systems performed the best followed by the screen/film system. The CCD based system showed better detection accuracy compared to the CR system in the ROC analysis. However, there was no significant difference between the CCD and the CR systems in the detectability analysis.

Recognition of detail in mammography  

NASA Astrophysics Data System (ADS)

In radiological practice the term recognition of detail is widely used. We examined how the term can be defined and interpreted, and how recognition of detail relates to radiological phantoms such as CDMAM (Contrast Detail Mammography). For tasks in visual perception a processing hierarchy can be assumed: The perception of a structure can occur at different processing levels, such as required in detection, discrimination, identification and recognition, with an ascending order of hierarchical relation. It is not always possible to predict from results at one hierarchy level those at another level. If an observer detects a structure, there is no prediction whether the observer will be able to discriminate the structure from another or whether he or she is even able to interpret the structure. Furthermore, the perceptibility of a detail is influenced by surrounding or overlapping anatomical noise. The presence of noise elevates visual thresholds and may change the overall perceptual behavior with regard to the examined parameter. Thus, perceptibility of structures (details) is strongly bound to the type of perceptual task and the image background used. Speaking of recognition of detail should not liberally extended to evaluating performance parameters of a technical system. If the term is applied, it needs to be specified how detail is characterized and which perceptual task is used for operationalizing recognition.

Details of 1? sr wide acceptance angle electrostatic lens for electron energy and two-dimensional angular distribution analysis combined with real space imaging  

NASA Astrophysics Data System (ADS)

We propose a new 1? sr Wide Acceptance Angle Electrostatic Lens (WAAEL), which works as a photoemission electron microscope (PEEM), a highly sensitive display-type electron energy and two-dimensional angular distribution analyzer. It can display two-dimensional angular distributions of charged particles within the acceptance angle of ±60° that is much larger than the largest acceptance angle range so far and comparable to the display-type spherical mirror analyzer developed by Daimon et al. [1]. It has good focusing capabilities with 5-times magnification and 27(4) ?m lateral-resolution. The relative energy resolution is typically from 2 to 5×10-3 depending on the diameter of energy aperture and the emission area on the sample.Although, the lateral resolution of the presented lens is far from those are available nowadays, but this is the first working model that can form images using charged particles collected from 1? sr wide acceptance angle. The realization of such lens system is one of the first possible steps towards reaching the field of imaging type atomic resolution electron microscopy Feynman et al. [2].Here some preliminary results are shown.

We present high-spatial resolution imaging obtained with the Submillimeter Array (SMA) at 880 ?m and the Keck adaptive optics (AO) system at the K S-band of a gravitationally lensed submillimeter galaxy (SMG) at z = 4.243 discovered in the Herschel Astrophysical Terahertz Large Area Survey. The SMA data (angular resolution ?0farcs6) resolve the dust emission into multiple lensed images, while the Keck AO K S-band data (angular resolution ?0farcs1) resolve the lens into a pair of galaxies separated by 0farcs3. We present an optical spectrum of the foreground lens obtained with the Gemini-South telescope that provides a lens redshift of z lens = 0.595 ± 0.005. We develop and apply a new lens modeling technique in the visibility plane that shows that the SMG is magnified by a factor of ? = 4.1 ± 0.2 and has an intrinsic infrared (IR) luminosity of L IR = (2.1 ± 0.2) × 1013 L ?. We measure a half-light radius of the background source of r s = 4.4 ± 0.5 kpc which implies an IR luminosity surface density of ?IR = (3.4 ± 0.9) × 1011 L ? kpc-2, a value that is typical of z > 2 SMGs but significantly lower than IR luminous galaxies at z ~ 0. The two lens galaxies are compact (r lens ? 0.9 kpc) early-types with Einstein radii of ?E1 = 0.57 ± 0.01 and ?E2 = 0.40 ± 0.01 that imply masses of M lens1 = (7.4 ± 0.5) × 1010 M ? and M lens2 = (3.7 ± 0.3) × 1010 M ?. The two lensing galaxies are likely about to undergo a dissipationless merger, and the mass and size of the resultant system should be similar to other early-type galaxies at z ~ 0.6. This work highlights the importance of high spatial resolution imaging in developing models of strongly lensed galaxies discovered by Herschel. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.

Detailed liver-specific imaging prior to pre-operative chemotherapy for colorectal liver metastases reduces intra-hepatic recurrence and the need for a repeat hepatectomy  

PubMed Central

Background Neoadjuvant chemotherapy for colorectal liver metastases (CRLM) reduces the accuracy of liver imaging which may understage patients pre-operatively. Retrospective review of a prospective database to determine whether liver-specific magnetic resonance imaging (MRI) prior to pre-operative chemotherapy affects intra-hepatic recurrence and long-term outcome after hepatectomy. Patients and methods Between 2003 and 2009, 242 patients with CRLM underwent a hepatectomy after ?3 cycles of oxaliplatin or irinotecan-based chemotherapy. All had a liver-specific MRI immediately pre-operatively. The outcome of patients who had a liver-specific MRI prior to chemotherapy (PCI group, n = 92) was compared with those who did not (non-PCI group, n = 150). Results A liver-specific MRI pre-chemotherapy changed the staging in 56% of patients. At a median (range) follow-up of 55 (6–94) months, there was a higher incidence of intra-hepatic recurrence at a new site in the non-PCI group (65% vs. 48% in the PCI group, P = 0.041) and an increased rate of recurrence in patients with the same number of lesions pre- and post-chemotherapy [hazard ratio (HR) 2.02, 1:10–3.37, P = 0.024]. The non-PCI group underwent more repeat hepatectomies than the PCI group (24.7% vs. 13%, P = 0.034), achieving similar long-term survival. Conclusions A liver-specific MRI prior to chemotherapy reduces intra-hepatic recurrence and avoids a repeat hepatectomy.

Place memory in crickets.  

PubMed

Certain insect species are known to relocate nest or food sites using landmarks, but the generality of this capability among insects, and whether insect place memory can be used in novel task settings, is not known. We tested the ability of crickets to use surrounding visual cues to relocate an invisible target in an analogue of the Morris water maze, a standard paradigm for spatial memory tests on rodents. Adult female Gryllus bimaculatus were released into an arena with a floor heated to an aversive temperature, with one hidden cool spot. Over 10 trials, the time taken to find the cool spot decreased significantly. The best performance was obtained when a natural scene was provided on the arena walls. Animals can relocate the position from novel starting points. When the scene is rotated, they preferentially approach the fictive target position corresponding to the rotation. We note that this navigational capability does not necessarily imply the animal has an internal spatial representation. PMID:18230590

The concept of demarketing, originally introduced by Kotler and Levy (1971), can be used in the context of places to describe specific activities aimed at deflecting interest, visitors, and\\/or investment to a particular place. This paper presents an exploratory investigation into the use of place demarketing in the UK. Thirteen in-depth interviews were conducted with place-marketing practitioners whose work was

Normal shoulder: MR imaging  

SciTech Connect

Relatively poor spatial resolution has been obtained in magnetic resonance (MR) imaging of the shoulder because the shoulder can only be placed in the periphery of the magnetic field. The authors have devised an anatomically shaped surface coil that enables MR to demonstrate normal shoulder anatomy in different planes with high spatial resolution. In the axial plane anatomy analogous to that seen on computed tomographic (CT) scans can be demonstrated. Variations in scapular position (produced by patient positioning) may make reproducibility of sagittal and coronal plane images difficult by changing the relationship of the plane to the shoulder anatomy. Oblique planes, for which the angle is chosen from the axial image, have the advantage of easy reproducibility. Obliquely oriented structures and relationships are best seen in oblique plane images and can be evaluated in detail.

New detail on auroral processes  

NASA Astrophysics Data System (ADS)

High-resolution imaging from spacecraft is revealing new detail on structures in bright, dynamic auroras. In the auroral regions where particles are accelerated to high energies, dynamic structures evolve on time scales of seconds or less, although the processes that drive particle acceleration and transfer of energy to small scales are not fully understood. Chaston et al. show how new spaceborne auroral imagery combined with simultaneous particle measurements can help improve understanding of the physical processes involved in the aurora. In particular, they show how magnetic reconnection (in which magnetic field lines break and reconnect, releasing energy), tearing, and sheared flows can transfer energy from larger to smaller scales and help form the auroral structures observed.

When tested on a tetO-LacZ transgenic background, doxycycline suppressed expression of beta-galactosidase in a tissue-specific manner. Reduced beta-galactosidase activity was detected in skin (basal layer of the epidermis and hair follicles), tongue, forestomach, and trachea. No reduction was seen in tissues that do not express endogenous keratin 5 (liver, spleen, muscle, heart, intestine).

This paper reports that the U.S., government should adopt policies that encourage U.S. petroleum companies to diversify crude oil sources around the world, says Conoco Inc. That's the key them underlying Conoco's latest world energy outlook through 2000. In its 1989 outlook, Conoco called on the U.S. government to open the Arctic National Wildlife Refuge Coastal Plain to exploration and development and provide a tax credit of $5/bbl of oil equivalent (BOE) for production from U.S. frontier areas as keys to reducing U.S. oil import dependence. Although Conoco included opening the ANWR Coastal Plain and more of the U.S. offshore among U.S. policy recommendations in its current outlook, the company placed the greatest emphasis on incentives for worldwide exploration.

Via Ca2+-imaging in freely behaving mice that repeatedly explored a familiar environment, we tracked thousands of CA1 pyramidal cells' place fields over weeks. Place coding was dynamic, for each day the ensemble representation of this environment involved a unique subset of cells. Yet, cells within the ?15–25% overlap between any two of these subsets retained the same place fields, which sufficed to preserve an accurate spatial representation across weeks.

Healthy Places: Exploring the Evidence  

PubMed Central

“Sense of place” is a widely discussed concept in fields as diverse as geography, environmental psychology, and art, but it has little traction in the field of public health. The health impact of place includes physical, psychological, social, spiritual, and aesthetic outcomes. In this article, the author introduces sense of place as a public health construct. While many recommendations for “good places” are available, few are based on empirical evidence, and thus they are incompatible with current public health practice. Evidence-based recommendations for healthy place making could have important public health implications. Four aspects of the built environment, at different spatial scales—nature contact, buildings, public spaces, and urban form—are identified as offering promising opportunities for public health research, and potential research agendas for each are discussed.

Innovative Plasma Imaging Array Concept  

NASA Astrophysics Data System (ADS)

A new lens/antenna array concept has been developed for millimeter-wave plasma imaging applications with dramatic increases in RF bandwidth and sensitivity. In this arrangement, an array of tightly coupled miniatured substrate lenses is fabricated such that each antenna has a dedicated substrate lens. The new arrangement exhibits low sidelobe levels over a bandwidth spanning 90 to 140 GHz for use in electron cyclotron emission imaging and microwave imaging reflectometry. An innovative ``vertical zoom'' control is also supported, which the vertical extent of the imaged plasma can be varied from 20 to 30 cm. The first plasma implementation of the new concept will take place on the TEXTOR tokamak in Fall 2008, with systems for DIII-D and ASDEX to follow in 2009. Experimental details regarding the imaging arrays and the new TEXTOR optical design will be presented.

The utility of hybrid single photon emission computed tomography/computed tomography imaging for primary hyperparathyroidism is both intuitive and becoming increasingly apparent clinically, particularly for patients with prior failed surgery and for those with suspected ectopic adenomas. Second generation imaging equipment, capable of superimposing functional information on highly detailed anatomic images is proving useful in surgical planning, permitting the successful application of minimally invasive techniques. The clinical background and hybrid imaging modality are discussed, together with a selection of illustrative case images. Special emphasis is placed on the use of the technique for imaging ectopic parathyroid adenomas. PMID:19851174

The devil is in the detail: children's recollection of details about their prior experiences.  

PubMed

Adults sometimes report highly specific details of childhood events, including the weather, what they or others were wearing, as well as information about what they or others said or were thinking at the time. When these details are reported in the course of research they shape our theories of memory development; when they are reported in a criminal trial they influence jurors' evaluation of guilt or innocence. The key question is whether these details were encoded at the time the event took place or have been added after the fact. We addressed this question prospectively by examining the memory accounts of children. In Experiment 1 we coded the reports of 5- to 6-year-olds and 9- to 10-year-olds who had experienced a unique event. We found that spontaneous mentions of these specific details were exceedingly rare. In Experiment 2 we questioned additional children about a similar event using specific questions to extract those details. We found that 9- to 10-year-olds were able to accurately answer, while 5- to 6-year-olds had considerable difficulty. Moreover, when the younger children did respond they provided generic, forensically inadequate, information. These data have important implications for the courtroom and for current theories of memory development and childhood amnesia. PMID:23116423

The astrophysics of crowded places  

NASA Astrophysics Data System (ADS)

Today the Sun is in a relatively uncrowded place. The distance between it and the nearest other star is relatively large (about 200,000 times the Earth-Sun distance!). This is beneficial to life on Earth; a close encounter with another star is extremely unlikely. Such encounters would either remove the Earth from its orbit around the Sun or leave it on an eccentric orbit similar to a comet's. But the Sun was not formed in isolation. It was born within a more-crowded cluster of perhaps a few hundred stars. As the surrounding gas evaporated away, the cluster itself evaporated too, dispersing its stars into the Galaxy. Virtually all stars in the Galaxy share this history, and here I will describe the role of 'clusterness' in a star's life. Stars are often formed in larger stellar clusters (known as open and globular clusters), some of which are still around today. I will focus on stars in globular clusters and describe how the interactions between stars in these clusters may explain the zoo of stellar exotica which have recently been observed with instruments such as the Hubble Space Telescope and the X-ray telescopes XMM-Newton and Chandra. In recent years, myriad planets orbiting stars other than the Sun-the so-called 'extrasolar' planets-have been discovered. I will describe how a crowded environment will affect such planetary systems and may in fact explain some of their mysterious properties.

Image processing for drift compensation in fluorescence microscopy  

NASA Astrophysics Data System (ADS)

Fluorescence microscopy is characterized by low background noise, thus a fluorescent object appears as an area of high signal/noise. Thermal gradients may result in apparent motion of the object, leading to a blurred image. Here, we have developed an image processing methodology that may remove/reduce blur significantly for any type of microscopy. A total of ~100 images were acquired with a pixel size of 30 nm. The acquisition time for each image was approximately 1 second. We can quantity the drift in X and Y using the sub pixel accuracy computed centroid location of an image object in each frame. We can measure drifts down to approximately 10 nm in size and a drift-compensated image can therefore be reconstructed on a grid of the same size using the "Shift and Add" approach leading to an image of identical size as the individual image. We have also reconstructed the image using a 3 fold larger grid with a pixel size of 10 nm. The resulting images reveal details at the diffraction limit. In principle we can only compensate for inter-image drift - thus the drift that takes place during the acquisition time for the individual image is not corrected. We believe that our results are of general applicability in microscopy and other types of imaging. A prerequisite for our method is the presence of a trackable object in the image such as a cell nucleus.

A contrast-detail comparison of computed mammotomography and digital mammography  

NASA Astrophysics Data System (ADS)

We use a contrast-detail observer study to compare performance of a novel 3D computed mammotomography (CmT) system with a commercially developed full-field digital mammography (FFDM) system. A contrast-detail phantom comprised of uniform acrylic spheres of various diameters was developed and placed in a variety of mediums including uniform water (simulating low contrast lesions within a uniform background), water and acrylic yarn (simulating low contrast lesions with over/under-lying structure), oil only (simulating higher contrast lesions in a uniform background), and oil and acrylic yarn (simulating higher contrast lesions with over/under-lying structure). For CmT, the phantom was placed in a 14.6 cm diameter uncompressed breast phantom and projections acquired using a simple circular orbit, W-target tube, 60 kVp tube potential, 0.05 cm Ce filtration, 4 mAs per projection, and a CsI(Tl) digital x-ray detector. Reconstructions used an iterative OSTR algorithm. For FFDM, the phantom was placed in a 5.3-cm-thick compressed breast phantom. Single CC-view mammograms were acquired using a clinical W-target tube with 50 um Rh filtration, 28 kVp, photo-timed mAs per our clinical mammography operation, and a Selenium-based flat-panel detector (Mammomat Novation, Siemens). Six observers evaluated the images in terms of the number of detectable spheres. FFDM performed significantly better for the low contrast lesions in uniform water background (p<0.05). However, CmT performed significantly better for all other cases (p<0.05). Results indicate that CmT shows significant advantage in soft tissue detection over FFDM in otherwise low contrast dense breasts.

Historical consideration of place: inviting multiple histories and narratives in place-based education  

NASA Astrophysics Data System (ADS)

Drawing upon van Eijck and Roth's notion of "place as chronotope," this review paper discusses historical consideration of place as it assists us to conceptualize place in its collective, political, and dialogical nature. In a place, we are positioned amidst of the multiplicity of histories and narratives within ever shifting various contexts of place. Historical consideration acknowledges multiplicity and marginalization in a place, thus, legitimizes multiple place histories and invites multiple narratives to engage in dialogical process of place. With historical consideration, place identity can be approached and framed in its collective, dialogical nature within larger social, political contexts of place. The paper further suggests that place based education should be able to acknowledge and invite multiple histories and marginalized voices of students into creating a place to dwell together.

Detailed Clinical Models: A Review  

PubMed Central

Objectives Due to the increasing use of electronic patient records and other health care information technology, we see an increase in requests to utilize these data. A highly level of standardization is required during the gathering of these data in the clinical context in order to use it for analyses. Detailed Clinical Models (DCM) have been created toward this purpose and several initiatives have been implemented in various parts of the world to create standardized models. This paper presents a review of DCM. Methods Two types of analyses are presented; one comparing DCM against health care information architectures and a second bottom up approach from concept analysis to representation. In addition core parts of the draft ISO standard 13972 on DCM are used such as clinician involvement, data element specification, modeling, meta information, and repository and governance. Results Six initiatives were selected: Intermountain Healthcare, 13606/OpenEHR Archetypes, Clinical Templates, Clinical Contents Models, Health Level 7 templates, and Dutch Detailed Clinical Models. Each model selected was reviewed for their overall development, involvement of clinicians, use of data types, code bindings, expressing semantics, modeling, meta information, use of repository and governance. Conclusions Using both a top down and bottom up approach to comparison reveals many commonalties and differences between initiatives. Important differences include the use of or lack of a reference model and expressiveness of models. Applying clinical data element standards facilitates the use of conceptual DCM models in different technical representations.

Frequency division multiplexed imaging  

NASA Astrophysics Data System (ADS)

In this paper, we describe frequency division multiplexed imaging (FDMI), where multiple images are captured simultaneously in a single shot and can later be extracted from the multiplexed image. This is achieved by spatially modulating the images so that they are placed at different locations in the Fourier domain. The technique assumes that the images are band-limited and they are placed at non-overlapping frequency regions through the modulation process. The FDMI technique can be used for extracting sub-exposure information and in applications where multiple cameras or captures are needed, such as high-dynamic-range and stereo imaging. We present experimental results to illustrate the FDMI idea.

NASA Astrophysics Data System (ADS)

Image fusion is an important problem in image analysis. The abundant detail information in multisource images should be preserved or even enhanced for the fused result. In this paper, using visual weight map extraction based on multiscale edge preserving decomposition, a details enhancing fusion algorithm is proposed. The saliency extraction based visual weight map is used for image fusion at different scales, which is decomposed by edge preserving image smooth approach. With this method, the details information which human visual system interests can be preserved and enhanced easily. The quantitative comparisons of experiments demonstrate that the proposed algorithm performs better than other methods, especially in visual effect and keeping details.

Microwave Imaging of Cotton Bales  

PubMed Central

Modern moisture restoration systems are increasingly capable of adding water to cotton bales. However, research has identified large variations in internal moisture within bales that are not readily monitored by current systems. While microwave moisture sensing systems can measure average bale moisture, this can be deceptive where water is unevenly distributed. In some cases, localized internal moisture levels exceed 7.5%, the upper safe limit for cotton bale storage, as determined by the USDA, as above this level, bales degrade and lose value. A high proportion of stored bales containing excess moisture have been discovered throughout the US in increasing numbers over the past several seasons, making the detection and prevention of this occurrence a critical goal. Previous research by the authors resulted in the development of microwave moisture-sensing technology. The current study examines an extension to this technology to allow for detailed cotton bale moisture imaging. The new technique incorporates a narrow beam imaging antenna coupled to a tomographic imaging algorithm. The imaging technique was able to resolve small (< 1 cm) high-permittivity structures against a low permittivity background. Moreover, the system was able to identify structures of known permittivity with high accuracy (coefficient of determination (r2) > 0.99). In preliminary testing on a wet commercial UD bale, the technique was able to accurately image and resolve the location of the pre-placed internal wet layer.

In-place HEPA filter penetration test  

SciTech Connect

We have demonstrated the feasibility of conducting penetration tests on high efficiency particulate air (HEPA) filters as installed in nuclear ventilation systems. The in-place penetration test, which is designed to yield equivalent penetration measurements as the standard DOP efficiency test, is based on measuring the aerosol penetration of the filter installation as a function of particle size using a portable laser particle counter. This in-place penetration test is compared to the current in-place leak test using light scattering photometers for single HEPA filter installations and for HEPA filter plenums using the shroud method. Test results show the in-place penetration test is more sensitive than the in-place leak test, has a similar operating procedure, but takes longer to conduct. Additional tests are required to confirm that the in-place penetration test yields identical results as the standard dioctyl phthalate (DOP) penetration test for HEPA filters with controlled leaks in the filter and gasket and duct by-pass leaks. Further development of the procedure is also required to reduce the test time before the in- place penetration test is practical.

Predicting contrast detail performance from objective measurements in digital mammography  

NASA Astrophysics Data System (ADS)

European Guidelines for quality control in digital mammography specify minimum and achievable standards of image quality in terms of threshold contrast, based on readings of images of the CDMAM test object by human observers. However the methodology is time-consuming and has large inter- and intra-observer error. To overcome these problems a software program is available to automatically read CDMAM images. An alternative approach would be to predict threshold contrast from measurements of DQE and MTF using a model of the imaging process. A simple signal-matched noise-integration model has been used to predict the contrast detail response of five different types of commercial digital mammography system (Siemens Inspiration, GE Senographe DS, and three types of Konica Minolta computerised radiography system). Measurements were made of the MTF and DQE of each detector and the noise equivalent apertures calculated. For each system sets of 16 images of the CDMAM test object were acquired at a range of dose levels and contrast-detail plots obtained using human observers and automated reading. The theoretically and experimentally determined threshold contrasts were compared. An encouragingly good level of agreement was found between the experimental data and theoretical predictions.

"From this place and of this place:" climate change, sense of place, and health in Nunatsiavut, Canada.  

PubMed

As climate change impacts are felt around the globe, people are increasingly exposed to changes in weather patterns, wildlife and vegetation, and water and food quality, access and availability in their local regions. These changes can impact human health and well-being in a variety of ways: increased risk of foodborne and waterborne diseases; increased frequency and distribution of vector-borne disease; increased mortality and injury due to extreme weather events and heat waves; increased respiratory and cardiovascular disease due to changes in air quality and increased allergens in the air; and increased susceptibility to mental and emotional health challenges. While climate change is a global phenomenon, the impacts are experienced most acutely in place; as such, a sense of place, place-attachment, and place-based identities are important indicators for climate-related health and adaptation. Representing one of the first qualitative case studies to examine the connections among climate change, a changing sense of place, and health in an Inuit context, this research draws data from a multi-year community-driven case study situated in the Inuit community of Rigolet, Nunatsiavut, Canada. Data informing this paper were drawn from the narrative analysis of 72 in-depth interviews conducted from November 2009 to October 2010, as well as from the descriptive analysis of 112 questionnaires from a survey in October 2010 (95% response rate). The findings illustrated that climate change is negatively affecting feelings of place attachment by disrupting hunting, fishing, foraging, trapping, and traveling, and changing local landscapes-changes which subsequently impact physical, mental, and emotional health and well-being. These results also highlight the need to develop context-specific climate-health planning and adaptation programs, and call for an understanding of place-attachment as a vital indicator of health and well-being and for climate change to be framed as an important determinant of health.

The role of images of information (charts, diagrams, maps, and symbols) for effective presentation of facts and concepts is expanding dramatically because of advances in computer graphics technology, increasingly hetero-lingual, hetero-cultural world target populations of information providers, the urgent need to convey more efficiently vast amounts of information, the broadening population of (non-expert) computer users, the decrease of available time for reading texts and for decision making, and the general level of literacy. A coalition of visual performance experts, human engineering specialists, computer scientists, and graphic designers/artists is required to resolve human factors aspects of images of information. The need for, nature of, and benefits of interdisciplinary effort are discussed.

Preference for place of care and place of death in palliative care: are these different questions?  

PubMed

Place of death is at times suggested as an outcome for palliative care services. This study aimed to describe longitudinal preferences for place of care and place of death over time for patients and their caregivers. Longitudinal paired data of patient/caregiver dyads from a prospective unblinded cluster randomised control trial were used. Patients and caregivers were separately asked by the palliative care nurse their preference at that time for place of care and place of death. Longitudinal changes over time for both questions were mapped; patterns of agreement (patient and caregiver; and preference for place of death when last asked and actual placed of death) were analysed with kappa statistics. Seventy-one patient/caregiver dyads were analysed. In longitudinal preferences, preferences for both the place of care (asked a mean of >6 times) and place of death (asked a mean of >4 times) changed for patients (28% and 30% respectively) and caregivers (31% and 30%, respectively). In agreement between patients and caregivers, agreement between preference of place of care and preferred place of death when asked contemporaneously for patients and caregivers was low [56% (kappa 0.33) and 36% (kappa 0.35) respectively]. In preference versus actual place of death, preferences were met for 37.5% of participants for home death; 62.5% for hospital; 76.9% for hospice and 63.6% for aged care facility. This study suggests that there are two conversations: preference for current place of care and preference for care at the time of death. Place of care is not a euphemism for place of death; and further research is needed to delineate these. Patient and caregiver preferences may not change simultaneously. Implications of any mismatch between actual events and preferences need to be explored. PMID:18755830

Towards a chronotopic theory of "place" in place-based education  

NASA Astrophysics Data System (ADS)

The notion of place, as in place- based education, has received considerable attention in educational theorizing because of its potential to link students, their lifeworlds, and their experiences in particular settings to formal education. However, in current debates of place-based education, the notion of place is emerging as problematic. The purpose of this study is to contribute to a rethinking of place in a form that is appropriate for describing and theorizing its occurrence in a world we share with others. We understand place as the result of a dialectical and dialogical relation of the material world and its chronotopic (time-space) nature in the various conversations (discourses) in which it is constituted as this place; that is, we view place as a lived entity that results from a dialogical transaction between a community and its material environment at a particular moment in cultural-historical time and which hence shapes and is shaped by the identity of the people. We exemplify our rethinking with a case of an environmental education project in which place unfolds as a chronotope from a dialogue between scientific and indigenous voices. The implications of this rethinking of place for place-based education are discussed.

Place attachment among retirees in Greensburg, Kansas.  

PubMed

On 4 May 2007 an ef-5 tornado leveled 95 percent of Greensburg, Kansas. Because city leaders encouraged everyone to use “green” building techniques as they rebuilt their homes and businesses, not only has the return to normalcy been exceedingly slow, but some of the town's older residents feel that officials have overlooked their needs. These minor episodes of discord enabled us to learn what features are most important to people in retirement. The features include identifiable landmarks, a space in which to socialize, and age-specific businesses. We assert that the lessons learned in Greensburg are applicable to other communities with a sizable older population. As baby boomers rapidly enter retirement they will seek places to live that are elder friendly and enable them to effectively bond with place. As previous research attests, people who have a strong attachment to place commonly have a good quality of life. PMID:22319811

Throughout its history, blood transfusion organization in France has established an exclusive exercise of the collection of blood and its components entrusted to doctors, thus creating the concept of "medicine of donation". This view is changing, and programmed exercise of this activity by nurses led to question about this profession perimeter, its necessary evolution, and finally about the place of physicians in blood supply.

REVIEW: Recent developments in breast imaging  

NASA Astrophysics Data System (ADS)

A review of breast imaging has already appeared in 1982 in this journal. Consequently, the present article concentrates on a discussion of only those developments of a more recent nature. Although the emphasis is placed on the physical aspects of the different imaging methods concerned, the essential factors relating to the clinical background and the associated radiation risk are also outlined. The completeness of detail depends on the present clinical importance of the method under discussion. X-ray mammography, which is still the most important breast imaging technique and has proved to be an effective method for breast cancer screening, is therefore treated in greater detail. Since the early 1980s, ultrasound B-mode scanning has evolved to an indispensable adjunct to x-ray mammography. For Doppler sonography, diaphanography, contrast-enhanced MRI, CT and DSA, the visualization of a tumour depends essentially on the enhanced vascularity of the lesion. Whether this will prove to be a reliable indicator for malignancy remains to be shown in controlled clinical studies. Common to all imaging systems is the increasing use of digital methods for signal processing, which also offers the possibility of computer-aided diagnosis by texture analysis and pattern recognition.

VAICo: Visual Analysis for Image Comparison.  

PubMed

Scientists, engineers, and analysts are confronted with ever larger and more complex sets of data, whose analysis poses special challenges. In many situations it is necessary to compare two or more datasets. Hence there is a need for comparative visualization tools to help analyze differences or similarities among datasets. In this paper an approach for comparative visualization for sets of images is presented. Well-established techniques for comparing images frequently place them side-by-side. A major drawback of such approaches is that they do not scale well. Other image comparison methods encode differences in images by abstract parameters like color. In this case information about the underlying image data gets lost. This paper introduces a new method for visualizing differences and similarities in large sets of images which preserves contextual information, but also allows the detailed analysis of subtle variations. Our approach identifies local changes and applies cluster analysis techniques to embed them in a hierarchy. The results of this process are then presented in an interactive web application which allows users to rapidly explore the space of differences and drill-down on particular features. We demonstrate the flexibility of our approach by applying it to multiple distinct domains. PMID:24051775

Corporate law, as it is traditionally taught, is primarily about shareholders, boards of directors, and managers, and the relationships among them. This is despite the fact that workers provide an essential input to a corporation's productive activities, and that the success of the business enterprise quite often turns

Prey Processing in Central Place Foragers  

Microsoft Academic Search

The importance of prey processing as an integral part of foraging behaviour has long been acknowledged, but little theoretical consideration has been given to the optimization of the processing behaviour itself. Processing renders food down to ingestible, palatable portions, and also removes non-essential mass thus reducing transport costs. Here, several models of processing are developed for a central place forager.

Aging in place and negotiated risk agreements.  

PubMed

An assisted living community (i.e., residence [ALR]) that responds to a resident's changing needs by adjusting services and level of care criteria means that the resident is less likely to be discharged to a higher level of care, such as a nursing home, and will "age in place." A "managed" or negotiated risk agreement (NRA) can facilitate aging in place by accommodating a resident's choices and potential risks of remaining in the residence. Although more than half the states speak to aging-in-place in their assisted living regulations, far fewer provide guidelines for negotiated risk discussion and its influence on service plans. Managing decline and the risks to a resident's safety and well-being can perhaps be addressed by "upstream palliative care," a concept and practice that respects a resident's quality of life interests while meeting and supporting their physical, mental, and emotional needs. This article discusses these issues as well as the capacity of a cognitively impaired/demented resident to enter into an NRA and its continuance when resident understanding is questionable, and dying-in-place.

HOSPITAL PHYSICS: Magnetic resonance imaging and spectroscopy  

NASA Astrophysics Data System (ADS)

Nuclear Magnetic Resonance (NMR) was first described in the scientific literature 50 years ago when Bloch and Purcell, working independently, showed how certain nuclei placed in a magnetic field absorbed energy in the radiofrequency range and re-emitted this energy during their transition back to the relaxed state (Bloch 1946, Purcell 1946). This phenomenon has since revolutionized medical imaging with its application in Magnetic Resonance Imaging (MRI) and in vivo Magnetic Resonance Spectroscopy (MRS). MRI produces pictures of `slices' through the human body with exquisite detail and contrast without the use of radiation, while in vivo MRS provides chemical information from selected areas in a similarly non-invasive way. This article describes some of the principles involved in the two techniques.

[Simejigahara, a place noted for moxa].  

PubMed

Shimejigahara is a place-name often used in old Waka (Japanese poems). It was reputed in the past to be a site rich in the plants moxa and mugwort. A study of this placed carried out. Shimejigahara, as mentioned in the literature of the Heian to Kamakura eras, seems to have been located at the site of the current Tochigi City. During the Edo era, however, Senjogahara in Nikko came to be referred to as Shimejigahara. In addition, some other places in what is now called Utsunomiya City, on Ibuki Mountain in Shiga Prefecture, and in Chiba City were referred to as Shimejigahara during the Edo era. When the types of wild mugwort seen in these various sites called "Shimejigahara" were searched for, Artemisia princeps P. was found in the cities of Tochigi, Utsunomiya and Chiba, while A. montana P. was seen in Senjogahara and on Ibuki Mountain. Papers published during the Edo era suggest that moxa, gathered in the Shimejigahara, was on the market during that period. It is, however, doubtful that the moxa produced from Shimejigahara was really commercialized, like the well-known "Ibuki moxa." PMID:11619106

In-place testing summary (1989)

Periodic evaluation of an air-cleaning system is necessary in order to establish a record of its current operating condition. These evaluations along with Health Physics air sampling determine whether air-cleaning integrity is being maintained. The in-place test is conducted in most instances without disrupting plant operations, and only if the systems failed the test would it become necessary to shut down. Testing is conducted on single and multi-stage filter systems and other filtration devices using optical particle counters. The testing procedure requires that the filter system be challenged with a test aerosol having a heterodisperse size distribution in the submicrometer diameter range, 0.1 to 1.0 micrometer. This type of testing is not to be confused with tests performed by the Quality Assurance Testing Stations, whose purpose is directed at filter efficiency. In-place testing of adsorber systems is required for several reasons: (1) chemical poisoning of the adsorbers by organic vapors; (2) settling of the charcoal in the bed due to vibration; and (3) installation defects. There are two methods of in-place testing of adsorber systems. The first method uses a fluorocarbon (Freon 11 gas), the second method uses a radioactive gas (Iodine or Methyl Iodide). At Los Alamos, we use the Freon 11 method. This report presents the results of the 1989 tests, including the methods and procedures used in the testing and calibration of the particle counters and aerosol diluter systems.

In-place filter testing summary  

SciTech Connect

The most common method of identifying particle penetration through a filter or adsorber system is through the performance of a periodic penetration test, i.e., in-place test or leak test using an aerosol or gas vapor to challenge the filter or adsorber system. The aerosol is usually formed by vaporization of a liquid, di-2(ethelhexyl sebacate) (DEHS), and allowed to condense to form liquid particles of a certain size and distribution. The gas vapor is formed by vaporization of Freon 11 liquid. The periodic penetration test, although conducted annually, can and has been demonstrated to show the beginning degradation of a filter or adsorber system. Other evidence of penetration can include detection of radiation downstream of the filter system or the existence of an unusually low pressure drop across the filter, i.e., torn filter, etc. However, these kinds of occurrences show up instantaneously and could release radioactive material to the atmosphere before the systems could be shut down. When a filter system fails the in--place test or is showing evidence of.filter or component degradation, corrective measures are put into place in order to return,the system back to its best operating condition. This report presents a summary of all filter tests.

Detailed geologic mapping of the Columbia Hills, Mars: West Spur to Cumberland Ridge  

NASA Astrophysics Data System (ADS)

The Columbia Hills in Gusev Crater is one of the most intensively studied regions on Mars. The Mars Exploration Rover (MER) Spirit has been investigating the Columbia Hills for over 5 years. During this time, Spirit has acquired thousands of images and spectroscopic observations from several outcrops and many soil samples and float rocks. The Hills exhibit a remarkable variety of textures and compositions, as indicated by diverse rock and soil types. Many studies of local regions within the Columbia Hills have been published from MER data, as have high-resolution Digital Elevation Models (DEMs) from the High Resolution Imaging Science Experiment (HiRISE) instrument on board the Mars Reconnaissance Orbiter (MRO). Additionally, the MRO Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument has acquired 13 hyperspectral observations of the Columbia Hills at 18m/pixel resolution. Previous work has had a spectroscopic and mineralogical focus, with sparsely-sampled structural measurements. To date, these data sets have not been integrated into a single detailed and comprehensive geologic map. We present a preliminary geologic map of the Columbia Hills. Our goal is to integrate observations from multiple instruments and spacecraft into a single map, illuminating the geographic context of geologic observations. Our study is unique in that we incorporate detailed structural measurements, localized stratigraphic sequences, and the footprints of remote sensing and in-situ observations. We also map the distribution of textures, such as vesicular vs. nodular rocks; small impact craters; probable flow margins; boundaries marking textural and color changes relating to differences in process and mineralogy; and the rover’s traverse path. We measure the strike and dip of planar features such as foliations and bedding planes from stereo-derived topography and provide estimates of the uncertainty in these measurements. We place the measurements in a regional geologic context in order to estimate the stratigraphic relationships between outcrops, and to compare structural attitudes to the local topography measured from the HiRISE DEM. Textures and possible impact craters are examined using Pancam, Navcam, and HiRISE images. Flow margins are estimated from both MER Pancam multispectral and HiRISE observations. Mineralogy is derived from rover and orbiter observations. By integrating many spectroscopic and imaging datasets obtained at different scales and mapping the geology in detail we can test hypotheses related to the formation and evolution of the Columbia Hills. Are the Hills primarily a volcanic construction, or are they a result of structural uplift from crater-forming processes? Were the carbonates, sulfates and diagenetic minerals discovered by Spirit the result of unrelated aqueous processes, or were they part of the same hydrothermal event? How are the modification processes shaping the evolution of the Hills different from what occurs on the surrounding plains?

We present an experimental realization of coherent diffraction imaging in reflection geometry illuminating the sample with a laser driven high harmonic generation (HHG) based XUV source. After recording the diffraction pattern in reflection geometry, the data must be corrected before the image can be reconstructed with a hybrid-input-output (HIO) algorithm. In this paper we present a detailed investigation of sources of spoiling the reconstructed image due to the nonlinear momentum transfer, errors in estimating the angle of incidence on the sample, and distortions by placing the image off center in the computation grid. Finally we provide guidelines for the necessary parameters to realize a satisfactory reconstruction within a spatial resolution in the range of one micron for an imaging scheme with a numerical aperture NA < 0.03.

Looking for Planets in all the Right Places  

NASA Astrophysics Data System (ADS)

Gravitational lensing has the potential to discover planets in orbits of all sizes, orbiting both nearby and distant stars. Until recently, however, searches for planets via lensing have been conducted by programs best suited to finding only a subset of planetary lenses. During the past year several new approaches have been developed, including searches for small periodic signals near baseline, and monitoring nearby stars. By taking these approaches, we will extend our search for planets to *all* the right places, and will increase the discovery rate. In addition, the extended lensing searches will discover nearby planetary systems that can subsequently be observed using the full range of planet-study techniques, including transit and radial velocity studies as well as direct imaging. I will talk about the theory and also about preliminary results from our monitoring of the first predicted lensing event for evidence of planets orbiting the nearby dwarf star VB 10.

Noradrenergic regulation of hippocampal place cells.  

PubMed

The influence of noradrenergic input to the hippocampus was assessed by recording hippocampal place cells and by modulating the noradrenergic tone with a selective agonist and antagonist of the alpha2-autoreceptors. The rats received intraperitoneal injection of 5 microg/kg of dexmedetomidine (DEX), an alpha2-agonist, 0.2 mg/kg of atipamezole (ATI), an alpha2-antagonist, or saline. Hippocampal place cells were recorded in a familiar rectangular environment and in three types of new environments (rectangle, square, and cylinder). Recordings in the familiar environment were conducted in two phases, either before (early phase) or after (late phase) the exposure to new environments. In the familiar environment, DEX significantly increased the mean firing rate of hippocampal interneurons, while ATI increased the mean firing rate of pyramidal cells. Only ATI in the early phase of the experiment impaired spatial selectivity. Both drugs induced field rotations in the early phase of the study, but in the late phase DEX decreased, while ATI increased field stability in the familiar environment. The drug effects in the new environment were dependent on degree of novelty. No difference between treatments was observed in the new rectangle, but in the square and cylinder, ATI increased the mean firing rate, number of fields, and field area compared to other treatments. Stability of the original firing fields in the familiar rectangle was dependent on type of interfering environment and drug treatment. Exposure to another rectangle had the smallest impact, and exposure to a square the largest impact, on the original field pattern. ATI impaired stability of the original field after exposure to a rectangular and cylinder, while the impairing effect of DEX was only observed after exposure to a cylinder. In conclusion, increased noradrenergic tone increases the firing rate of hippocampal place cells, especially when the experimental situation and environment are new, but this increase is spatially nonselective. Furthermore, manipulation of the noradrenergic tone in either direction leads to instability of firing fields. PMID:11811674

Earth Science needs a tools market place!  

NASA Astrophysics Data System (ADS)

Utilizing Earth science data in scientific research is difficult because of its complexity. One needs to leverage an range of tools to search, locate, access and analyze Earth science data. It is not the dearth of tools that make utilizing Earth science data difficult. On the contrary, there are too many tools available to researchers. Each tool is designed for a specific project, purpose or end user. Consequently, the researchers are burdened to find these tools and then learn how to use them effectively. A solution to solving this problem is creating a tools market place. However, just creating a registry of tools is not enough. In order for wider adoption by the research community, the tools should be implemented as components of an accepted open architecture and institutional neutral framework. The need for creating a market place is evident. The market place will serve as a platform to connect application developers to potential end users within the research community. The rationale for requiring the tools to be built as components for a framework is two-fold: First, it will allow researchers to incorporate these new tools to their existing analysis workbench to create customized applications for their specific needs. Second, it will benefit the application developers as their tools will be adopted by a wider set of users within the research community. Most application developers tend to develop tools either from scratch or use their own in-house frameworks because it offers a path of least resistance to development. The disadvantage with this approach is that even the best-designed and open source tools get labeled with the 'Not Invented Here' tag. This perception causes other application developers to balk at adopting technology developed at other institutions. Therefore, it is important for the Earth science community to adopt an institutional neutral framework to force application developers to create plug and play components. Two examples of popular open frameworks that can be leveraged for scientific desktop and web applications are Eclipse and Drupal respectively. The proposed approach requires convincing the Earth science application developers to adopt open frameworks and invest time to learn them. Funding agencies can assist in forging this direction by recommending institutional neutral, open frameworks as a basis for new tools. Moving in this direction will reduce redundant development effort in the future and create a true tools market place for the Earth science.

Electrohydrodynamic ``drop-and-place'' particle deployment  

NASA Astrophysics Data System (ADS)

The ``drop-and-place'' paradigm aims at delivering and positioning liquid drops using a pulsed electrohydrodynamic jet. On-demand drops much smaller than the diameter of the delivery nozzle may also contain particles. We report proof-of-concept experiments on the delivery of single 2 ?m diameter particles using a 50 ?m nozzle and identify the control parameters for dosing and positioning accuracies. A positioning accuracy at the micrometer level is achieved by eliminating contact line pinning on a hydrophobic surface and minimizing impingement-induced motion. The dosing statistics follow the random Poisson distribution, indicating that single-particle accuracy can be achieved using a gating mechanism.

Repetitive convulsant-induced seizures reduce the number but not precision of hippocampal place cells.  

PubMed

Repetitive one-per-day seizures induced in otherwise normal rats by the volatile convulsant flurothyl decrease the accuracy of locating a hidden goal without changing the mean location of goal selection. We now show that an 8-d series of such seizures degrades the spatial signal carried by the firing of hippocampal pyramidal cells and specifically reduces the information conveyed by the place cell subset of pyramidal cells. This degradation and a concomitant slowing of the hippocampal theta rhythm occur over time courses parallel to the development of the behavioral deficit and plausibly account for the impairment. The details of how pyramidal cell discharge weakens are, however, unexpected. Rather than a reduction in the precision of location-specific firing distributed evenly over all place cells, the number of place cells decreases with seizure number, although the remaining place cells remain quite intact. Thus, with serial seizures there is a cell-specific conversion of robust place cells to sporadically firing (<0.1 spike/s) "low-rate" cells as opposed to gradual loss of place cell resolution. This transformation occurs in the absence of significant changes in the discharge rate of hippocampal interneurons, suggesting that the decline in the number of place cells is not a simple matter of increased inhibitory tone. The cumulative transformation of place cells to low-rate cells by repetitive seizures may reflect a homeostatic, negative-feedback process. PMID:22442080

Introduction: modern airs, waters, and places.  

PubMed

Twenty-four centuries have passed since the doctrine of AirsWaters Places was articulated in the Hippocratic corpus, promoting a mutually constitutive vision of humankind and climate. Yet the "airs, waters, places tradition" has proved remarkably resilient and adaptable as a framing device for relations among nations, natural and human resources, and human health. Redeployed in diverse historical contexts across time, the relationship between climate and humans has evolved from a dependent one in which human constitution and health are determined by climate to an interdependent one in which humans and climate influence one another. Recent scholarship extends the ways in which historians of colonial medicine, neo-Hippocratic medicine, public health, tropical disease, and race have characterized the climate-human nexus and its attendant politics. Through the exploration of the works of circumnavigators, physicians, physiologists, ecologists, geographers, paleoanthropologists, and economists, contributors to this special issue offer some new and sometimes challenging interpretations of medical climatology: beyond the link between tropical medicine and colonialism, beyond temperate versus tropical, beyond latitude to think of altitude.

POSITIVE EMOTIONS ENHANCE RECALL OF PERIPHERAL DETAILS  

PubMed Central

Emotional arousal and negative affect enhance recall of central aspects of an event. However, the role of discrete emotions in selective memory processing is understudied. Undergraduates were asked to recall and rate autobiographical memories of eight emotional events. Details of each memory were rated as central or peripheral to the event. Significance of the event, vividness, reliving and other aspects of remembering were also rated for each event. Positive affect enhanced recall of peripheral details. Furthermore, the impairment of peripheral recall was greatest in memories of anger, not of fear. Reliving the experience at retrieval was negatively correlated with recall of peripheral details for some emotions (e.g., anger) but not others (e.g., fear), irrespective of similarities in affect and intensity. Within individuals, recall of peripheral details was correlated with less belief in the memory’s accuracy and more likelihood to recall the memory from one’s own eyes (i.e., a field perspective).

Hippocampal cells encode places by forming small anatomical clusters  

PubMed Central

The hippocampus has been hypothesized to function as a “spatial” or “cognitive” map, however, the functional cellular organization of the spatial map remains a mystery. The majority of electrophysiological studies, thus far, have supported the view of a random-type organization in the hippocampus. However, using immediate early genes (IEGs) as an indicator of neuronal activity, we recently observed a cluster-type organization of hippocampal principal cells, whereby a small number (~4) of nearby cells were activated in animals exposed to a restricted part of an environment. To determine the fine structure of these clusters and to provide a 3D image of active hippocampal cells that encode for different parts of an environment, we established a functional mapping of immediate early genes (IEGs) zif268 and Homer1a, using in situ hybridization and 3D-reconstruction imaging methods. We found that, in animals exposed to the same location twice, there were significantly more double IEG-expressing cells, and the clusters of nearby cells were more “tightly” formed, in comparison to animals exposed to two different locations. We propose that spatial encoding recruits specific cell ensembles in the hippocampus and that with repeated exposure to the same place the ensembles become better organized to more accurately represent the “spatial map”.

Composite imaging method for histological image analysis.  

PubMed

A composite imaging method has been developed that enables the user to directly capture a composite image by one-image capturing. It was experimentally verified that the composite images of bright-field, dark-field, and phase-contrast images can be captured with an arbitrary composition ratio. The difference in pixel values between the captured composite image and the computer composite image was small. This imaging method is realized only by placing below the condenser a masking plate, which can easily be made using Neutral Density filters. Therefore, little additional time and cost are needed. The composite imaging method was applied for extracting Helicobacter pylori in microscopic images of HE-stained gastric histological sections. H pylori is difficult to extract because the colors in H pylori are similar to those in other areas. It is experimentally shown that a composite image of phase-contrast and dark-field images captured using the proposed method improves the accuracy for extracting H pylori. PMID:24110455

Detailed analysis of the silicon surface under low-energy oxygen bombardment at atomic resolution  

NASA Astrophysics Data System (ADS)

A detailed analysis of the amorphous-SiO2/crystalline-Si(011) interface formed by low-energy oxygen bombardment is performed by high-resolution Rutherford backscattering spectroscopy and spherical aberration-corrected scanning transmission electron microscopy (STEM). The atomic level analyses indicated a few nanometers of displaced Si atoms layer immediately below the synthetic SiO2 layer. A comparison between intensities of the high-angle annular dark field (HAADF) STEM image and the simultaneously acquired high-angle bright-field (HABF) STEM image shows that both intensities decreased at the existing layer of displaced Si atoms, and the relationship between these intensities cannot be explained by conventional image formation mechanisms. From detailed investigations using STEM imaging simulations, the HAADF STEM and HABF STEM images, which were simulated based on a realistic model, revealed the random distribution of a crystalline material and amorphous material at the interface; and this result agrees well with experimental results.

Placing late Neanderthals in a climatic context.  

PubMed

Attempts to place Palaeolithic finds within a precise climatic framework are complicated by both uncertainty over the radiocarbon calibration beyond about 21,500 14C years bp and the absence of a master calendar chronology for climate events from reference archives such as Greenland ice cores or speleothems. Here we present an alternative approach, in which 14C dates of interest are mapped directly onto the palaeoclimate record of the Cariaco Basin by means of its 14C series, circumventing calendar age model and correlation uncertainties, and placing dated events in the millennial-scale climate context of the last glacial period. This is applied to different sets of dates from levels with Mousterian artefacts, presumably produced by late Neanderthals, from Gorham's Cave in Gibraltar: first, generally accepted estimates of about 32,000 14C years bp for the uppermost Mousterian levels; second, a possible extended Middle Palaeolithic occupation until about 28,000 14C years bp; and third, more contentious evidence for persistence until about 24,000 14C years bp. This study shows that the three sets translate to different scenarios on the role of climate in Neanderthal extinction. The first two correspond to intervals of general climatic instability between stadials and interstadials that characterized most of the Middle Pleniglacial and are not coeval with Heinrich Events. In contrast, if accepted, the youngest date indicates that late Neanderthals may have persisted up to the onset of a major environmental shift, which included an expansion in global ice volume and an increased latitudinal temperature gradient. More generally, our radiocarbon climatostratigraphic approach can be applied to any 'snapshot' date from discontinuous records in a variety of deposits and can become a powerful tool in evaluating the climatic signature of critical intervals in Late Pleistocene human evolution.

Neuronal mechanisms of phencyclidine-induced place aversion and preference in the conditioned place preference task.  

PubMed

Place conditioning paradigms are widely used for determining the motivational properties of drugs. Phencyclidine (PCP) has been a common drug of abuse during the past two decades and has a rewarding effect in animals. However, PCP produces place aversion in the conditioned place preference (CPP) task in animals. Here, we report the possible neuronal mechanisms of PCP-induced place aversion and preference in the CPP task in rodents. In naive rats and mice, PCP dose-dependently produced place aversion and PCP had a significant effect at the doses of 4 and 8 mg/kg in rats and mice, respectively. The aversive effect of PCP (4 mg/kg) in rats was significantly attenuated by ritanserin (3 and 10 mg/kg), a serotonin 15-HT2) receptor antagonist whereas the lesion of serotonergic (5-HTergic) neurons by 5,7-dihydroxytryptamine (100 micrograms i.c.v.) and alpha-methyl-rho-tyrosine (AMPT; 100 mg/kg), a tyrosine hydroxylase inhibitor, did not affect the aversive effect of PCP. In rats pretreated with PCP (10 mg/kg/day) for 14 days, tolerance was developed to PCP (4 mg/kg)-induced place aversion. In rats and mice pretreated with PCP (10 mg/kg/day) for 28 days, however, PCP dose-dependently produced place preference but not aversion. The preferred effect of PCP (8 mg/kg) in mice preteated with PCP (10 mg/kg/day for 28 days) was significantly attenuated by AMPT (100 mg/kg) and 6-hydroxydopamine (100 micrograms i.c.v.) a dopaminergic (DAergic) neurotoxin, but not by DSP-4 (30 mg/kg), a noradrenergic neurotoxin and ritanserin. In mice pretreated with methamphetamine (1 mg/kg/day) for 14 days, PCP (8 mg/kg) produced place preference. These findings suggest that 5-HTergic and DAergic systems are involved in the PCP-induced place aversion and preference, respectively, and some changes in the neuronal systems including DAergic systems, induced by repeated PCP treatment play a critical role in the addiction of PCP.

Automating Shallow Seismic Imaging  

SciTech Connect

Our primary research focus during the current three-year period of funding has been to develop and demonstrate an automated method of conducting two-dimensional (2D) shallow-seismic surveys with the goal of saving time, effort, and money. Recent tests involving the second generation of the hydraulic geophone-planting device dubbed the ''Autojuggie'' have shown that large numbers of geophones can be placed quickly and automatically and can acquire high-quality data, although not under all conditions (please see the Status and Results of Experiments sections for details). In some easy-access environments, this device is expected to make shallow seismic surveying considerably more efficient and less expensive. Another element of our research plan involved monitoring the cone of depression around a pumping well, with the well serving as a proxy location for fluid-flow at a contaminated DOE site. To try to achieve that goal, we collected data from a well site at which drawdown equilibrium had been reached and at another site during a pumping test. Data analysis disclosed that although we were successful in imaging the water table using seismic reflection techniques (Johnson, 2003), we were not able to explicitly delineate the cone of depression (see Status and Results of Experiments).

Stellar Imager  

NASA Astrophysics Data System (ADS)

The Stellar Imager (SI) is one of NASA's "Vision Missions" - concepts for future, space-based, strategic missions that could enormously increase our capabilities for observing the Cosmos. SI is designed as a UV/Optical Interferometer which will enable 0.1 milli-arcsecond (mas) spectral imaging of stellar surfaces and, via asteroseismology, stellar interiors and of the Universe in general. The ultra-sharp images of the Stellar Imager will revolutionize our view of many dynamic astrophysical processes by transforming point sources into extended sources, and snapshots into evolving views. SI, with a characteristic angular resolution of 0.1 milli-arcseconds at 2000 Angstroms, represents an advance in image detail of several hundred times over that provided by the Hubble Space Telescope. The Stellar Imager will zoom in on what today-with few exceptions - we only know as point sources, revealing processes never before seen, thus providing a tool as fundamental to astrophysics as the microscope is to the study of life on Earth. SI's science focuses on the role of magnetism in the Universe, particularly on magnetic activity on the surfaces of stars like the Sun. It's prime goal is to enable long-term forecasting of solar activity and the space weather that it drives, in support of the Living With a Star program in the Exploration Era. SI will also revolutionize our understanding of the formation of planetary systems, of the habitability and climatology of distant planets, and of many magneto-hydrodynamically controlled processes in the Universe. Stellar Imager is included as a "Flagship and Landmark Discovery Mission" in the 2005 Sun Solar System Connection (SSSC) Roadmap and as a candidate for a "Pathways to Life Observatory" in the Exploration of the Universe Division (EUD) Roadmap (May, 2005) and as such is a candidate mission for the 2025-2030 timeframe. An artist's drawing of the current "baseline" concept for SI is presented.

There is overwhelming evidence that the maintenance of enteral feeding is beneficial in patients in whom oral access has been diminished or lost. Short-term enteral access is usually achieved via naso-enteral tube placement. For longer term tube feeding there are recognised advantages for enteral feeding tubes placed percutaneously. The provision of a percutaneous enteral tube feeding service should be within the remit of the hospital nutrition support team (NST). This designated team should provide a framework for patient selection, pre-assessment and post-procedural care. Close working relations with community-based services should be established. An accredited therapeutic endoscopist should be a member of the NST and direct the technical aspects of the service. Every endoscopy unit in an acute hospital setting should provide a basic percutaneous endoscopic gastrostomy (PEG) service. This should include provision for fitting a PEG jejunal extension (PEGJ) if required. Specialist units should be identified where a more comprehensive service is provided, including direct jejunal placement (DPEJ), as well as radiological and laparoscopically placed tubes. Good understanding of the indications for percutaneous enteral tube feeding will prevent inappropriate procedures and ensure that the correct feeding route is selected at the appropriate time. Each unit should adopt and become familiar with a limited range of PEG tube equipment. Careful adherence to the important technical details of tube insertion will reduce peri-procedural complications. Post-procedural complications remain relatively common, however, and an awareness of the correct approach to managing them is essential for all clinicians involved in providing a percutaneous enteral tube feeding service. Finally, ethical considerations should always be taken into account when considering long-term enteral feeding, especially for patients with a poor quality of life. PMID:21071581

Memory for Details with Self-Referencing  

PubMed Central

Self-referencing benefits item memory, but little is known about the ways in which referencing the self affects memory for details. Experiment 1 assessed whether the effects of self-referencing operate only at the item, or general, level or also enhance memory for specific visual details of objects. Participants incidentally encoded objects by making judgments in reference to the self, a close other (one’s mother), or a familiar other (Bill Clinton). Results indicate that referencing the self or a close other enhances both specific and general memory. Experiments 2 and 3 assessed verbal memory for source in a task that relied on distinguishing between different mental operations (internal sources). Results indicate that self-referencing disproportionately enhances source memory, relative to conditions referencing other people, semantic, or perceptual information. We conclude that self-referencing not only enhances specific memory for both visual and verbal information, but can disproportionately improve memory for specific internal source details as well.

Image use in field guides and identification keys: review and recommendations  

PubMed Central

Background and aims Although illustrations have played an important role in identification keys and guides since the 18th century, their use has varied widely. Some keys lack all illustrations, while others are heavily illustrated. Even within illustrated guides, the way in which images are used varies considerably. Here, we review image use in paper and electronic guides, and establish a set of best practices for image use in illustrated keys and guides. Scope Our review covers image use in both paper and electronic guides, though we only briefly cover apps for mobile devices. With this one exception, we cover the full range of guides, from those that consist only of species descriptions with no keys, to lavishly illustrated technical keys. Emphasis is placed on how images are used, not on the operation of the guides and key, which has been reviewed by others. We only deal with operation when it impacts image use. Main points Few illustrated keys or guides use images in optimal ways. Most include too few images to show taxonomic variation or variation in characters and character states. The use of multiple images allows easier taxon identification and facilitates the understanding of characters. Most images are usually not standardized, making comparison between images difficult. Although some electronic guides allow images to be enlarged, many do not. Conclusions The best keys and guides use standardized images, displayed at sizes that are easy to see and arranged in a standardized manner so that similar images can be compared across species. Illustrated keys and glossaries should contain multiple images for each character state so that the user can judge variation in the state. Photographic backgrounds should not distract from the subject and, where possible, should be of a standard colour. When used, drawings should be prepared by professional botanical illustrators, and clearly labelled. Electronic keys and guides should allow images to be enlarged so that their details can be seen.

The Influence Of Choice Of Fundamental Catalogue On Calculated Apparent Places Of Stars  

NASA Astrophysics Data System (ADS)

The paper has been inspired with changes of the concepts and definitions concerning celestial reference systems and frames approved and recommended by the resolutions of the General Assembly of the International Astronomical Union. The paper presents an extensive discussion of the results of computations of apparent places of stars based on the FK5 catalogue data and the contemporary Hipparcos and FK6 catalogue data. Detailed analysis of the effect of fundamental catalogue data i.e. the differences between the old and contemporary catalogue data on the values of calculated apparent places of stars was made. The effect of changes of precession-nutation model and definition of the celestial reference system was analysed too. The paper contains also an analysis of time variability of the calculated apparent places and specifies the problems of interpolation and presentation of calculated data in a tabulated form used in the astronomical almanacs. The paper completes detailed results and conclusions drawn from the analyses and computations performed. These are: a conclusion of presence of large, reaching some hundreds of mas, systematic differences between the FK5 and Hipparcos catalogue data; showing the relative rotation of about 20 mas between FK5 and HCRF catalogue celestial reference frames; and pointing out the catalogue errors as the major source of the errors of calculated apparent places. Still, the switch from the FK5 to Hipparcos catalogue data and from FK5 to HCRF catalogue celestial reference frame gives an improvement in calculated apparent places accuracy by an order of magnitude.

A comparative contrast-detail study of five medical displays  

SciTech Connect

The objective of this study was to compare the contrast-detail performance of five different commercial liquid crystal displays (LCDs) to other LCD and cathode-ray tube (CRT) displays for medical applications. A contrast-detail phantom, supplemented with 5 in. of acrylic, was imaged on a commercial digital radiographic system using techniques comparable to chest radiography. The phantom design enabled observer evaluation by a four-alternative forced choice paradigm. The acquired images were independently scored by five observers on five medical display devices: a 5 megapixel monochrome LCD, a 3 megapixel monochrome LCD, a 9 megapixel color LCD, a 5 megapixel monochrome CRT, and a mammographic-grade monochrome CRT. The data were analyzed using the method suggested by the manufacturer based on a nearest neighbor correction technique. They were further analyzed using a logistic regression response model with a natural threshold using an overall chi-square test for display type followed by pairwise comparisons for individual display performance. The differences between the display devices were small. The standard analysis of the results based on the manufacturer-recommended method did not yield any statistically discernible trend among displays. The logistic regression analysis, however, indicated that the 5 megapixel monochrome LCD was statistically significantly (p<0.0001) superior to the others, followed by the 3 megapixel monochrome LCD (p<0.0001). The three other displays exhibited lower but generally similar performance characteristics. The findings suggest that 5 and 3 megapixel monochrome LCDs provide comparable but subtly superior contrast detectability than other tested displays, with the former performing slightly better in the detection of subtle and fine details.

NASA Astrophysics Data System (ADS)

Here we present a new all-atom model and development of simple potential functions (inspired by discoveries of general principles of protein folding) that allow to fold small proteins from sequence to near native structure at an atomic level of detail. Availability of numerous successful all-atom folding trajectories and their novel graph theoretical analysis, makes it possible to gain a detailed atomic level understanding of folding pathways/intermediates/transition states for engrailed homeodomain - a small alpha-helical protein that has been recently studied experimentally.

A detailed 3D model of the guinea pig cochlea.  

PubMed

Several partial models of cochlear subparts are available. However, a complete 3D model of an intact cochlea based on actual histological sections has not been reported. Hence, the aim of this study was to develop a novel 3D model of the guinea pig cochlea and conduct post-processes on this reconstructed model. We used a combination of histochemical processing and the method of acquiring section data from the visible human project (VHP) to obtain a set of ideal raw images of cochlear sections. After semi-automatic registration and accurate manual segmentation with professional image processing software, one set of aligned data and six sets of segmented data were generated. Finally, the segmented structures were reconstructed by 3D Slicer (a professional imaging process and analysis tool). Further, post-processes including 3D visualization and a virtual endoscope were completed to improve visualization and simulate the course of the cochlear implant through the scala tympani. The 3D cochlea model contains the main six structures: (1) the inner wall, (2) modiolus and spiral lamina, (3) cochlea nerve and spiral ganglion, (4) spiral ligament and inferior wall of cochlear duct, (5) Reissner's membrane and (6) tectorial membrane. Based on the results, we concluded that ideal raw images of cochlear sections can be acquired by combining the processes of conventional histochemistry and photographing while slicing. After several vital image processing and analysis steps, this could further generate a vivid 3D model of the intact cochlea complete with internal details. This novel 3D model has great potential in teaching, basic medical research and in several clinical applications. PMID:17717692

[The place of confocal microscopy in gynecology].  

PubMed

The confocal microscopy is an optical imaging technique that allows true optical biopsies and a three-dimensional visualization of tissue sections and cells. The analysis of the signal is done thanks to reflected light (reflectance confocal microscopy) or to the fluorescence emitted by tissues (fluorescence confocal microscopy). The use of confocal microscopy in the gynecological field is still experimental and is mainly about the ex vivo and in vivo diagnosis of cervical dysplasia and ovary cancer. The miniaturization of the probes could allow an endoscopic use for the diagnosis of endometrial or ovary cancers. We aim to present the principles of confocal microscopy and to expose the main ways of research and the future and potential clinical applications of this technique in gynecology. PMID:17997232

Hydrologic synthesis: Across processes, places, and scales  

NASA Astrophysics Data System (ADS)

Hydrologic synthesis, I believe, is needed in at least three respects: across processes, where the challenge is how to represent complex interacting dynamic systems including feedbacks between system components; across places, where the challenge is how to synthesize the plethora of case studies around the world in the past decades; and across scales, where one is interested in the general characteristics of processes as a function of space and time scales for the same site or an ensemble of sites. Seeking explanations for patterns, puzzles, and paradoxes is the way toward synthesis, and this should be pursued through two approaches. The first is to engage in more complex model building, but model complexity may ultimately limit the practical applicability of these models. The alternative is to seek more parsimonious avenues to synthesis. One of them is classification and similarity concepts which, generally speaking, can be profitably used when the processes are not fully understood. This often is the case in hydrology. Among the key unresolved issues and research challenges in hydrology is separating the predictable and the unpredictable. Synthesis, I think, needs to focus on the patterns of predictability. There is also an important, alternative, role of models in water resources management using models as communication tools. The best model then is not the most accurate one but the one that serves best the purpose of reaching a consensus among the players.

The place of culture in forensic psychiatry.  

PubMed

Members of a multicultural society must all be subject to the same equitable system of justice. However, culture exerts profound influences on human behavior, and cultural considerations have a place in determinations of capacity and in appropriate sentencing. Cultural psychiatry can contribute to forensic psychiatry by helping to contextualize individuals' actions and experiences. This contextualizing can be done through cultural consultations that employ interpreters and culture brokers to identify the role of culture in individuals' psychopathology. Clarifying how cultural background has affected individuals' capacity to form a criminal intent or control their behavior may allow a better determination of level of culpability and guide appropriate sentencing. However, framing behavior as culturally influenced may also stereotype and stigmatize specific groups. To avoid this, culture must be understood in terms of power relationships between minority groups and the dominant society. Cultural factors are not only relevant to the experience of specific groups but pervade the entire judicial system shaping the process of moral and legal reasoning. PMID:17389351

Differential connectivity within the Parahippocampal Place Area.  

PubMed

The Parahippocampal Place Area (PPA) has traditionally been considered a homogeneous region of interest, but recent evidence from both human studies and animal models has suggested that PPA may be composed of functionally distinct subunits. To investigate this hypothesis, we utilize a functional connectivity measure for fMRI that can estimate connectivity differences at the voxel level. Applying this method to whole-brain data from two experiments, we provide the first direct evidence that anterior and posterior PPA exhibit distinct connectivity patterns, with anterior PPA more strongly connected to regions in the default mode network (including the parieto-medial temporal pathway) and posterior PPA more strongly connected to occipital visual regions. We show that object sensitivity in PPA also has an anterior-posterior gradient, with stronger responses to abstract objects in posterior PPA. These findings cast doubt on the traditional view of PPA as a single coherent region, and suggest that PPA is composed of one subregion specialized for the processing of low-level visual features and object shape, and a separate subregion more involved in memory and scene context.

The place of suxamethonium in pediatric anesthesia.  

PubMed

Suxamethonium is a drug that promotes very strong views both for and against its use in the context of pediatric anesthesia. As such, the continuing debate is an excellent topic for a 'Pro-Con' debate. Despite ongoing efforts by drug companies, the popular view still remains that there is no single neuromuscular blocking drug that can match suxamethonium in terms of speed of onset of neuromuscular block and return of neuromuscular control. However, with this drug the balance of benefit vs risk and side effects are pivotal. Suxamethonium has significant adverse effects, some of which can be life threatening. This is particularly relevant for pediatric anesthesia because the spectrum of childhood diseases may expose susceptible individuals to an increased likelihood of adverse events compared with adults. Additionally, the concerns related to airway control in the infant may encourage the occasional pediatric anesthetist to use the drug in preference to slower onset/offset drugs. In the current environment of drug research, surveillance and licensing, it is debatable whether this drug would achieve the central place it still has in pediatric anesthesia. The arguments for and against its use are set out below by our two international experts, Marcin Rawicz from Poland and Barbara Brandom from USA. This will allow the reader an objective evaluation with which to make an informed choice about the use of suxamethonium in their practice. PMID:19645973

[School: a place for studying and eating].  

PubMed

This study seeks to discuss the significance of school nutrition expressed by students in public schools from the state of Bahia, Brazil. The objective is to understand the symbolic aspects associated with school nutrition. The results of a survey into the significance of nutrition offered by the Brazilian School Nutrition Program (PNAE) expressed by students from six public schools in municipalities in the state of Bahia, Brazil, are presented. A qualitative approach to understand nutrition at school and notions about healthy food by analyzing oral and written narratives of adolescents is used. The reports point to opposing stances between food in the home and food outside the home. What is customary can appear strange depending on the time and place. In this sense, they do not make an association between healthy food and PNAE. The food culture requires students to eat food on two occasions: breakfast and lunch (or dinner). These are aspects that are distinct, however they must be combined in school, because for these social actors, studying and eating are necessities that complement each other. PMID:23670374

High throughput, detailed, cell-specific neuroanatomy of dendritic spines using microinjection and confocal microscopy  

PubMed Central

Morphological features such as size, shape and density of dendritic spines have been shown to reflect important synaptic functional attributes and potential for plasticity. Here we describe in detail a protocol for obtaining detailed morphometric analysis of spines using microinjection of fluorescent dyes, high resolution confocal microscopy, deconvolution and image analysis using NeuronStudio. Recent technical advancements include better preservation of tissue resulting in prolonged ability to microinject, and algorithmic improvements that compensate for the residual Z-smear inherent in all optical imaging. Confocal imaging parameters were probed systematically for the identification of both optimal resolution as well as highest efficiency. When combined, our methods yield size and density measurements comparable to serial section transmission electron microscopy in a fraction of the time. An experiment containing 3 experimental groups with 8 subjects in each can take as little as one month if optimized for speed, or approximately 4 to 5 months if the highest resolution and morphometric detail is sought.
