HUBBLE CAPTURES DETAILED IMAGE OF URANUS' ATMOSPHERE  

NASA Technical Reports Server (NTRS)

Hubble Space Telescope has peered deep into Uranus' atmosphere to see clear and hazy layers created by a mixture of gases. Using infrared filters, Hubble captured detailed features of three layers of Uranus' atmosphere. Hubble's images are different from the ones taken by the Voyager 2 spacecraft, which flew by Uranus 10 years ago. Those images - not taken in infrared light - showed a greenish-blue disk with very little detail. The infrared image allows astronomers to probe the structure of Uranus' atmosphere, which consists of mostly hydrogen with traces of methane. The red around the planet's edge represents a very thin haze at a high altitude. The haze is so thin that it can only be seen by looking at the edges of the disk, and is similar to looking at the edge of a soap bubble. The yellow near the bottom of Uranus is another hazy layer. The deepest layer, the blue near the top of Uranus, shows a clearer atmosphere. Image processing has been used to brighten the rings around Uranus so that astronomers can study their structure. In reality, the rings are as dark as black lava or charcoal. This false color picture was assembled from several exposures taken July 3, 1995 by the Wide Field Planetary Camera-2.

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.

Efficiency of low-contrast detail detectability in fluoroscopic imaging.  

PubMed

The detectability of a static low-contrast detail in the dynamic fluoroscopic image of a homogeneous phantom was assessed by physical measurement of the signal-to-noise ratio (SNR) and by psychophysical measurement of the human observer detectability index d'. The two-alternative forced-choice method was used for human observer tests. The image data consisted of digitally recorded fluoroscopic image sequences which were displayed in a continuous loop of varying length (1-50 frames) at a rate of 25 frames/s. Human detection performance was seen to improve with the SNR in all cases studied: when the signal was made stronger, the image noise lower, or when the SNR in the image sequence was made higher by increasing the length of the image sequence. The results imply that the statistical efficiency of humans decreases slowly when the number of frames in the displayed loop is increased. This decrease of efficiency with loop length was not seen in all test series, however, and it is possible that the phenomenon is partly related to the high d' values found at the greatest loop lengths studied. When the display contrast was high, the statistical efficiency of the human observer was 30%-40% for both static and dynamic images. The efficiency was somewhat lower, 15%-25%, for images that were displayed with a display contrast gain setting more typical of fluoroscopy. The accumulation rate of SNR2 is a suitable quantity for the measurement of fluoroscopic image quality as related to a given static signal detection task. In contrast to this, visibility measurement by determination of the threshold contrast was seen to be unacceptably imprecise if the test is based on only one observer's opinion, as is often the case in practical quality assurance testing. The precision of the threshold contrast measurement could, however, be improved by using several observers and test objects with a smaller step between details than is usual. PMID:9167156

Detailed images of asteroid 25143 Itokawa from Hayabusa.  

PubMed

Rendezvous of the Japanese spacecraft Hayabusa with the near-Earth asteroid 25143 Itokawa took place during the interval September through November 2005. The onboard camera imaged the solid surface of this tiny asteroid (535 meters by 294 meters by 209 meters) with a spatial resolution of 70 centimeters per pixel, revealing diverse surface morphologies. Unlike previously explored asteroids, the surface of Itokawa reveals both rough and smooth terrains. Craters generally show unclear morphologies. Numerous boulders on Itokawa's surface suggest a rubble-pile structure. PMID:16741110

Maia X-ray fluorescence imaging: Capturing detail in complex natural samples  

NASA Astrophysics Data System (ADS)

Motivated by the challenge of capturing complex hierarchical chemical detail in natural material from a wide range of applications, the Maia detector array and integrated realtime processor have been developed to acquire X-ray fluorescence images using X-ray Fluorescence Microscopy (XFM). Maia has been deployed initially at the XFM beamline at the Australian Synchrotron and more recently, demonstrating improvements in energy resolution, at the P06 beamline at Petra III in Germany. Maia captures fine detail in element images beyond 100 M pixels. It combines a large solid-angle annular energy-dispersive 384 detector array, stage encoder and flux counter inputs and dedicated FPGA-based real-time event processor with embedded spectral deconvolution. This enables high definition imaging and enhanced trace element sensitivity to capture complex trace element textures and place them in a detailed spatial context. Maia hardware and software methods provide per pixel correction for dwell, beam flux variation, dead-time and pileup, as well as off-line parallel processing for enhanced throughput. Methods have been developed for real-time display of deconvoluted SXRF element images, depth mapping of rare particles and the acquisition of 3D datasets for fluorescence tomography and XANES imaging using a spectral deconvolution method that tracks beam energy variation.

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.

Functional imaging of hippocampal place cells at cellular resolution during virtual navigation  

PubMed Central

Spatial navigation is a widely employed behavior in rodent studies of neuronal circuits underlying cognition, learning and memory. In vivo microscopy combined with genetically-encoded indicators provides important new tools to study neuronal circuits, but has been technically difficult to apply during navigation. We describe methods to image the activity of hippocampal CA1 neurons with sub-cellular resolution in behaving mice. Neurons expressing the genetically encoded calcium indicator GCaMP3 were imaged through a chronic hippocampal window. Head-fixed mice performed spatial behaviors within a setup combining a virtual reality system and a custom built two-photon microscope. Populations of place cells were optically identified, and the correlation between the location of their place fields in the virtual environment and their anatomical location in the local circuit was measured. The combination of virtual reality and high-resolution functional imaging should allow for a new generation of studies to probe neuronal circuit dynamics during behavior.

Recursive, in-place algorithm for the hexagonal orthogonal oriented quadrature image pyramid  

NASA Technical Reports Server (NTRS)

Pyramid image transforms have proven useful in image coding and pattern recognition. The hexagonal orthogonal oriented quadrature image pyramid (HOP), transforms an image into a set of orthogonal, oriented, odd and even bandpass subimages. It operates on a hexagonal input lattice and employs seven kernels, each of which occupies a neighborhood consisting of a point and a hexagon of six nearest neighbors. The kernels consist of one lowpass and six bandpass kernels that are orthogonal, self-similar, and localized in space, spatial frequency, orientation, and phase. The kernels are first applied to the image samples to create the first level of the pyramid, then to the lowpass coefficients to create the next level. The resulting pyramid is a compact, efficient image code. Here, a recursive, in-place algorithm for computation of the HOP transform is described. The transform may be regarded as a depth-first traversal of a tree structure. It is shown that the algorithm requires a number of operations that is on the order of the number of pixels.

Cloud Imagers Offer New Details on Earth's Health  

NASA Technical Reports Server (NTRS)

A stunning red sunset or purple sunrise is an aesthetic treat with a scientific explanation: The colors are a direct result of the absorption or reflectance of solar radiation by atmospheric aerosols, minute particles (either solid or liquid) in the Earth s atmosphere that occur both naturally and because of human activity. At the beginning or end of the day, the Sun s rays travel farther through the atmosphere to reach an observer s eyes and more green and yellow light is scattered, making the Sun appear red. Sunset and sunrise are especially colorful when the concentration of atmospheric particles is high. This ability of aerosols to absorb and reflect sunlight is not just pretty; it also determines the amount of radiation and heat that reaches the Earth s surface, and can profoundly affect climate. In the atmosphere, aerosols are also important as nuclei for the condensation of water droplets and ice crystals. Clouds with fewer aerosols cannot form as many water droplets (called cloud particles), and consequently, do not scatter light well. In this case, more sunlight reaches the Earth s surface. When aerosol levels in clouds are high, however, more nucleation points can form small liquid water droplets. These smaller cloud particles can reflect up to 90 percent of visible radiation to space, keeping the heat from ever reaching Earth s surface. The tendency for these particles to absorb or reflect the Sun s energy - called extinction by astronomers - depends on a number of factors, including chemical composition and the humidity and temperature in the surrounding air; because cloud particles are so small, they are affected quickly by minute changes in the atmosphere. Because of this sensitivity, atmospheric scientists study cloud particles to anticipate patterns and shifts in climate. Until recently, NASA s study of atmospheric aerosols and cloud particles has been focused primarily on satellite images, which, while granting large-scale atmospheric analysis, limited scientists ability to acquire detailed information about individual particles. Now, experiments with specialized equipment can be flown on standard jets, making it possible for researchers to monitor and more accurately anticipate changes in Earth s atmosphere and weather patterns.

Detection of Toxocara eggs in contaminated soil from various public places of Chennai city and detailed correlation with literature.  

PubMed

Toxocarosis is one of the most prevalent human helminthosis caused by larvae of Toxocara canis and Toxocara cati, the most widely distributed nematode parasites of dogs and cats respectively. Soil is considered as the principal source of transmission of Toxocara infection to human beings. With increasing population of dogs and cats, soil contamination with ova or eggs of Toxocara can be detected in public and private locations of city backyards, playgrounds, streets, sand pits and so on, regardless of the season of the year. In this context the present study was carried out to estimate the extent of soil contamination with Toxocara eggs in public parks, playgrounds and few kennels situated in different parts of Chennai city. A total of 105 soil samples from 40 public places and 5 kennels were screened for the presence of parasitic eggs. Toxocara eggs were recovered from 5 soil samples indicating an overall prevalence rate of 4.75 %. Out of 80 samples collected from public places, three samples, one each from Mogappair, My lady park (Periamet) and Madras Veterinary College showed the presence of Toxocara spp. eggs indicating an overall prevalence of 3.75 per cent. Out of the 25 samples from 5 kennels, two samples one each from Tambaram and Thorappakkam kennels were positive for Toxocara eggs with prevalence of 8 per cent. Low prevalence of Toxocara eggs in soil samples of these areas can be attributed to the less population of pups, the carriers of adult worms and the active source of soil contamination. The progress made in ABC (animal birth control) programme carried out by both governmental and non-governmental organizations has contributed to reduction of birth rate in dogs and thereby reduced the chances of soil contamination with Toxocara eggs to a certain extent in Chennai city.

Detail preserved fusion of infrared and visual images by using opening and closing based toggle operator  

NASA Astrophysics Data System (ADS)

Image fusion is an effective way to combine the useful information in infrared and visual images. One crucial part of infrared and visual image fusion is extracting the useful image features of the original images, and thus maintaining the image details in the final fusion image well. In this paper, a detail preserving algorithm for infrared and visual image fusion based on the multi-scale toggle operator which uses morphological opening and closing operators as primitives is proposed. The toggle operator using opening and closing as primitives is discussed. Also, extracting image regions using the constructed toggle operator is demonstrated. Then, based on the multi-scale theory, extraction of multi-scale image regions using the constructed toggle operator is demonstrated. After appropriately utilizing the extracted multi-scale image features, the effective fusion result is obtained through the strategy of contrast enlargement. Experimental results show that, because the toggle operator using opening and closing as primitives could extract image features well in the original infrared and visual images, the proposed algorithm performs well for detail preserved fusion of infrared and visual images.

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

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.

To ensure real-time update of the quality metric and interactive level-of-detail decisions, we propose a summary table scheme in response to runtime transfer function changes and a GPU-based solution for visibility estimation. Experimental results on large scientific and medical data sets demonstrate the effectiveness and efficiency of our algorithm. PMID:17093341

Investigating the visual inspection subjectivity on the contrast-detail evaluation in digital mammography images  

NASA Astrophysics Data System (ADS)

A major difficulty in the interpretation of mammographic images is the low contrast and, in the case of early detection of breast cancer, the reduced size of the features of malignancy on findings such as microcalcifications. Furthermore, image assessment is subject to significant reliance of the capacity of observation of the expert that will perform it, compromising the final diagnosis accuracy. Thinking about this aspect, this study evaluated the subjectivity of visual inspection to assess the contrast-detail in mammographic images. For this, we compared the human readings of images generated with the CDMAM phantom performed by four observers, enabling to determining a threshold of contrast visibility in each diameter disks present in the phantom. These thresholds were compared graphically and by statistical measures allowing us to build a strategy for use of contrast and detail (dimensions) as parameters of quality in mammography.

Detailed analysis of latencies in image-based dynamic MLC tracking  

SciTech Connect

Purpose: Previous measurements of the accuracy of image-based real-time dynamic multileaf collimator (DMLC) tracking show that the major contributor to errors is latency, i.e., the delay between target motion and MLC response. Therefore the purpose of this work was to develop a method for detailed analysis of latency contributions during image-based DMLC tracking. Methods: A prototype DMLC tracking system integrated with a linear accelerator was used for tracking a phantom with an embedded fiducial marker during treatment delivery. The phantom performed a sinusoidal motion. Real-time target localization was based on x-ray images acquired either with a portal imager or a kV imager mounted orthogonal to the treatment beam. Each image was stored in a file on the imaging workstation. A marker segmentation program opened the image file, determined the marker position in the image, and transferred it to the DMLC tracking program. This program estimated the three-dimensional target position by a single-imager method and adjusted the MLC aperture to the target position. Imaging intervals {Delta}T{sub image} from 150 to 1000 ms were investigated for both kV and MV imaging. After the experiments, the recorded images were synchronized with MLC log files generated by the MLC controller and tracking log files generated by the tracking program. This synchronization allowed temporal analysis of the information flow for each individual image from acquisition to completed MLC adjustment. The synchronization also allowed investigation of the MLC adjustment dynamics on a considerably finer time scale than the 50 ms time resolution of the MLC log files. Results: For {Delta}T{sub image}=150 ms, the total time from image acquisition to completed MLC adjustment was 380{+-}9 ms for MV and 420{+-}12 ms for kV images. The main part of this time was from image acquisition to completed image file writing (272 ms for MV and 309 ms for kV). Image file opening (38 ms), marker segmentation (4 ms), MLC position calculation (16 ms), and MLC adjustment (52 ms) were considerably faster. For {Delta}T{sub image}=1000 ms, the total time from image acquisition to completed MLC adjustment increased to 1030{+-}62 ms (MV) and 1330{+-}52 ms (kV) mainly because of delayed image file writing. The MLC adjustment duration was constant 52 ms ({+-}3 ms) for MLC adjustments below 1.1 mm and increased linearly for larger MLC adjustments. Conclusions: A method for detailed time analysis of each individual real-time position signal for DMLC tracking has been developed and applied to image-based tracking. The method allows identification of the major contributors to latency and therefore a focus for reducing this latency. The method could be an important tool for the reconstruction of the delivered target dose during DMLC tracking as it provides synchronization between target motion and MLC motion.

TOPICAL REVIEW: Small animal SPECT and its place in the matrix of molecular imaging technologies  

NASA Astrophysics Data System (ADS)

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.

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

Place of modern imaging modalities for solitary plasmacytoma: toward improved primary staging and treatment monitoring.  

PubMed

Radiation therapy (RT) is the mainstay of treatment of solitary plasmacytoma. In most cases, doses ranging from 40 to 50 Gy yield in a local control more than 80%. However, the prognosis of patients with SP is marked by a high rate of transformation to multiple myeloma (MM), and there is no demonstrated benefit of adjuvant chemotherapy for decreasing this probability. However, clinical benefits could be reached from improving screening for other primary sites of plasmacytoma and earlier discovering signs suggestive of MM. Since such strategy could provide significant information regarding both prognosis and therapy, it has become first importance to improve initial staging of tumor widespread. Although conventional skeletal X-ray survey remains standard, usual sensitivity of radiographies does not permit diagnosing early myeloma lesions and a significant number of patients with supposed SP might be understaged and do not receive the appropriate treatment. The development of more sensitive and specific imaging modalities will make it feasible to earlier detect subclinical lesions, thus leading lead to new approaches in the treatment strategies. Here, we discuss the benefits and limitations of magnetic resonance imaging and positron emission tomography for primary staging of patients with solitary plasmacytoma. Both imaging modalities could also improve target volume delineation and assessment of tumor response after RT. PMID:21621417

TIMED Observations of the Signatures of Magnetic Activity in the MLTI Region placed into Global Context by ACE, POLAR, IMAGE, SAMPEX, FAST, NOAA/POES, and DMSP  

NASA Astrophysics Data System (ADS)

This talk focuses on the signatures of magnetic activity as seen in perturbations of neutral winds, composition, minor species chemistry, and temperature observed by the GUVI, TIDI and SABER instruments on the TIMED spacecraft during its first months of operations. In particular, several moderate magnetic storms occurred during February 2-9, 2002 and a number of small solar proton events occurred in January and February. Auroral energy inputs measured at high resolution by the GUVI instrument are placed into the global context through comparison with IMAGE FUV and POLAR UVI lower-resolution images of the full auroral oval. Magnetic storm evolution is tracked using ENA observations from IMAGE which detail the build-up and asymmetries in the ring current source of high-energy ions for the MLTI. FAST, SAMPEX, NOAA POES and DMSP provide in-situ information on particles and fields to confirm and enhance the remote view provided by the TIMED/GUVI instrument and, in addition, supply information on the highest energy particles that penetrate deep into the lower thermosphere/mesosphere, perturbing the basic state observed by TIMED. The combination of these data sets provides a view of the sun-Earth chain down to one of its last links.

Imaging the internal structure of fluid upflow zones with detailed digital Parasound echosounder surveys  

NASA Astrophysics Data System (ADS)

Sites of venting fluids both with continuous and episodic supply often reveal complex surface and internal structures, which are difficult to image and cause problems to transfer results from local sampling towards a structural reconstruction and a quantification of (average) flux rates. Detailed acoustic and seismic surveys would be required to retrieve this information, but also an appropriate environment, where fluid migration can be properly imaged from contrasts to unaffected areas. Hemipelagic sediments are most suitable, since typically reflectors are coherent and of low lateral amplitude variation and structures are continuous over distances much longer than the scale of fluid migration features. During RV Meteor Cruise M473 and RV Sonne Cruise SO 149 detailed studies were carried out in the vicinity of potential fluid upflow zones in the Lower Congo Basin at 5oS in 3000 m water depth and at the Northern Cascadia Margin in 1000 m water depth. Unexpected sampling of massive gas hydrates from the sea floor as well as of carbonate concretions, shell fragments and different liveforms indicated active fluid venting in a typically hemipelagic realm. The acoustic signature of such zones includes columnar blanking, pockmark depressions at the sea floor, association with small offset faults (< 1m). A dedicated survey with closely spaced grid lines was carried out with the Parasound sediment echosounder (4 kHz), which data were digitally acquired with the ParaDigMA System for further processing and display, to image the spatial structure of the upflow zones. Due to the high data density amplitudes and other acoustic properties could be investigated in a 3D volume and time slices as well as reflector surfaces were analyzed. Pronounced lateral variations of reflection amplitudes within a complex pattern indicate potential pathways for fluid/gas migration and occurrences of near-surface gas hydrate deposits, which may be used to trace detailed surface evidence from side scan sonar imaging down to depth and support dedicated sampling.

Evaluation of a software package for automated quality assessment of contrast detail images—comparison with subjective visual assessment  

NASA Astrophysics Data System (ADS)

Contrast detail analysis is commonly used to assess image quality (IQ) associated with diagnostic imaging systems. Applications include routine assessment of equipment performance and optimization studies. Most frequently, the evaluation of contrast detail images involves human observers visually detecting the threshold contrast detail combinations in the image. However, the subjective nature of human perception and the variations in the decision threshold pose limits to the minimum image quality variations detectable with reliability. Objective methods of assessment of image quality such as automated scoring have the potential to overcome the above limitations. A software package (CDRAD analyser) developed for automated scoring of images produced with the CDRAD test object was evaluated. Its performance to assess absolute and relative IQ was compared with that of an average observer. Results show that the software does not mimic the absolute performance of the average observer. The software proved more sensitive and was able to detect smaller low-contrast variations. The observer's performance was superior to the software's in the detection of smaller details. Both scoring methods showed frequent agreement in the detection of image quality variations resulting from changes in kVp and KERMAdetector, which indicates the potential to use the software CDRAD analyser for assessment of relative IQ.

Detailed imaging of flowing structures at depth using microseismicity: a tool for site investigation?  

NASA Astrophysics Data System (ADS)

Field evidence shows that faults and fractures can act as focused pathways or barriers for fluid migration. This is an important property for modern engineering problems, e.g., CO2 sequestration, geological radioactive waste disposal, geothermal energy exploitation, land reclamation and remediation. For such applications the detailed characterization of the location, orientation and hydraulic properties of existing fractures is necessary. These investigations are expensive, requiring the hire of expensive equipment (excavator or drill rigs), which incur standing charges when not in use. In addition, they only provide information for discrete sample 'windows'. Non-intrusive methods have the ability to gather information across an entire area. Methods including electrical resistivity/conductivity and ground penetrating radar (GRP), have been used as tools for site investigations. Their imaging ability is often restricted due to unfavourable on-site conditions e.g. GRP is not useful in cases where a layer of clay or reinforced concrete is present. Our research has shown that high quality seismic data can be successfully used in the detailed imaging of sub-surface structures at depth; using induced microseismicity data recorded beneath the Açu reservoir in Brazil we identified orientations and values of average permeability of open shear fractures at depths up to 2.5km. Could microseismicity also provide information on the fracture width in terms of stress drops? First results from numerical simulations showed that higher stress drop values correspond to narrower fractures. These results were consistent with geological field observations. This study highlights the great potential of using microseismicity data as a supplementary tool for site investigation. Individual large-scale shear fractures in large rock volumes cannot currently be identified by any other geophysical dataset. The resolution of the method is restricted by the detection threshold of the local seismic networks used for the monitoring of the seismic activity. However, it could be significantly increased if complete seismic data sets were available using high-sensitivity seismographs e.g. nanoseismic monitoring.

Detailed investigation of self-imaging in multimode photonic crystal waveguides for applications in power and polarization beam splitters  

NASA Astrophysics Data System (ADS)

Properties of the self-imaging effect based on multimode interference (MMI) in multimode photonic crystal waveguides (PCWs) are investigated and analyzed in detail. By combining photonic band gap (PBG) and total internal reflection (TIR) effects in PCWs, self-imaging phenomena are achieved for both TE and TM polarizations. To observe the images reproduced by this self-imaging phenomenon, finite-difference time-domain (FDTD) simulations are performed on a multi-mode PCW. From these numerical simulations the reproduced images are identified and their positions along the propagation axis are described. We also, present the design and simulation of novel polarization-insensitive power splitter and polarization splitter. The simulation results show that the optimized devices have excellent transmission efficiencies as well as wide operating frequency bandwidths and small structure size. So, the proposed devices are promising and may play an important role in high-density photonic integrated circuits in the future.

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.

Detailed Study of Defects in Silicon Solar Cells by Cathodoluminescence Spectrum Imaging: Preprint  

SciTech Connect

We have recently developed a spectrum imaging system for cathodoluminescence (CLsi) at NREL, which has been successfully applied to different semiconductors. The advanced multi-channel detection required for CLsi consists of an ultrafast spectrum acquisition triggered by the electron beam during scanning. Spectra are acquired either with a Roper Scientific silicon EEV-1340400 cryogenic CCD or an InGaAs 5121 cryogenic PDA, depending on the range of spectral emission. Acquisition times by pixel are typically of 10 to 20 ms (180 seconds for a 100100 pixel image). The output of spectrum imaging measurements is thus represented by a series of emission spectra. CCDIMAG, the software developed for CLsi, processes this spectrum series to reconstruct monochromatic images or extract the spectrum from any area on the image. This system is operated on the JEOL-5800 scanning electron microscope (SEM). CLsi measurements can be performed at temperatures between 15 K and 300 K. A low-vibration ARS Displex DE-202 closed-circuit cryostat provides cryogenic operation. The interface for vibration isolation has been developed to be compatible with SEM observation.

Detailed study of scratch drive actuator characteristics using high-speed imaging  

NASA Astrophysics Data System (ADS)

Microactuators are one of the key components in MEMS and Microsystems technology, and various designs have been realized through different fabrication processes. One type of microactuator commonly used is the scratch drive actuator (SDA) that is frequently fabricated by surface micromachining processes. An experimental investigation has been conducted on the characteristics of SDAs fabricated using the Cronos Microsystems MUMPs process. The motivation is to compare the response of SDAs located on the same die, and SDAs located on the different dies from the same fabrication batch. A high-speed imaging camera has been used to precisely determine important SDA characteristics such as step size, velocity, maximum velocity, and acceleration over long travel distance. These measurements are important from a repeatability point of view, and in order to fully exploit the potential of the SDA as a precise positioning mechanism. 2- and 3-stage SDAs have been designed and fabricated for these experiments. Typical step sizes varying from 7 nm at a driving voltage of 60 V to 23 nm at 290 V have been obtained.

Psychophysical evaluation of the image quality of a dynamic flat-panel digital x-ray image detector using the threshold contrast detail detectability (TCDD) technique  

NASA Astrophysics Data System (ADS)

We are currently in an era of active development of the digital X-ray imaging detectors that will serve the radiological communities in the new millennium. The rigorous comparative physical evaluations of such devices are therefore becoming increasingly important from both the technical and clinical perspectives. The authors have been actively involved in the evaluation of a clinical demonstration version of a flat-panel dynamic digital X-ray image detector (or FDXD). Results of objective physical evaluation of this device have been presented elsewhere at this conference. The imaging performance of FDXD under radiographic exposure conditions have been previously reported, and in this paper a psychophysical evaluation of the FDXD detector operating under continuous fluoroscopic conditions is presented. The evaluation technique employed was the threshold contrast detail detectability (TCDD) technique, which enables image quality to be measured on devices operating in the clinical environment. This approach addresses image quality in the context of both the image acquisition and display processes, and uses human observers to measure performance. The Leeds test objects TO[10] and TO[10+] were used to obtain comparative measurements of performance on the FDXD and two digital spot fluorography (DSF) systems, one utilizing a Plumbicon camera and the other a state of the art CCD camera. Measurements were taken at a range of detector entrance exposure rates, namely 6, 12, 25 and 50 (mu) R/s. In order to facilitate comparisons between the systems, all fluoroscopic image processing such as noise reduction algorithms, were disabled during the experiments. At the highest dose rate FDXD significantly outperformed the DSF comparison systems in the TCDD comparisons. At 25 and 12 (mu) R/s all three-systems performed in an equivalent manner and at the lowest exposure rate FDXD was inferior to the two DSF systems. At standard fluoroscopic exposures, FDXD performed in an equivalent manner to the DSF systems for the TCDD comparisons. This would suggest that FDXD would therefore perform adequately in a clinical fluoroscopic environment and our initial clinical experiences support this. Noise reduction processing of the fluoroscopic data acquired on FDXD was also found to further improve TCDD performance for FDXD. FDXD therefore combines acceptable fluoroscopic performance with excellent radiographic (snap shot) imaging fidelity, allowing the possibility of a universal x-ray detector to be developed, based on FDXD's technology. It is also envisaged that fluoroscopic performance will be improved by the development of digital image enhancement techniques specifically tailored to the characteristics of the FDXD detector.

High-resolution single-molecule recognition imaging of the molecular details of ricin-aptamer interaction.  

PubMed

We studied the molecular details of DNA aptamer-ricin interactions. The toxic protein ricin molecules were immobilized on a Au(111) surface using a N-hydroxysuccinimide (NHS) ester to specifically react with lysine residues located on the ricin B chains. A single ricin molecule was visualized in situ using the AFM tip modified with an antiricin aptamer. Computer simulation was used to illustrate the protein and aptamer structures, the single-molecule ricin images on a Au(111) surface, and the binding conformations of ricin-aptamer and ricin-antibody complexes. The various ricin conformations on a Au(111) surface were caused by the different lysine residues reacting with the NHS ester. It was also observed that most of the binding sites for aptamer and antibody on the A chains of ricin molecules were not interfered by the immobilization reaction. The different locations of the ricin binding sites to aptamer and antibody were also distinguished by AFM recognition images and interpreted by simulations. PMID:22489938

Detailed effects of scattering and absorption by haze and aerosols in the atmosphere on the average point spread function of an imaging system.  

PubMed

The Earth's atmosphere has significant effects on the propagation of electromagnetic (EM) radiation and accordingly degrades the performance of electro-optical systems. These effects are attributed to atmospheric turbulence and to absorption and scattering of EM waves by atmospheric molecules and aerosols. In this paper we develop a detailed model of the effects of absorption and scattering on the optical radiation propagating from the object plane to an imaging system based on the classical theory of EM scattering. Scattering has the effect of de-correlating the light leaving the target from the unscattered light reaching the imaging system, and scattering has the effect of broadening the angle at which the scattered light arrives at the receiver compared to the unscattered light. Absorption has the effect of reducing the amount of power available for the image. Both of these effects depend upon the atmospheric species present, their EM properties, and wavelength. We use this detailed model to compute the average point spread function (PSF) of an imaging system that properly accounts for the effects of the diffraction and scattering, and the appropriate optical power level of both the unscattered and the scattered radiation arriving at the pupil of the imaging system. Since the scattered radiation is temporally and spatially de-correlated from the unscattered radiation, we model the effects of the unscattered radiation and the radiation scattered from the various species as additive in the image plane. The key result of this study is the significant effect of atmospheric scattering on the contrast and spatial resolution of images acquired by imaging systems, due to the increased level of the scattered radiation PSF and the reduced level of the direct radiation PSF, upon increasing the atmospheric optical depth.

Limitations Placed on the Time Coverage, Isoplanatic Patch Size and Exposure Time for Solar Observations Using Image Selection Procedures in the Presence of Telescope Aberrations  

NASA Astrophysics Data System (ADS)

Image selection, adaptive optics and post-facto image restoration methods are all techniques being used for diffraction limited imaging with ground-based solar and stellar telescopes. Often these techniques are used in a hybrid form like e.g. the application of adaptive optics and/or post-facto image restoration in combination with already good images obtained by image selection in periods of good seeing. Fried (JOSA 56, 1372, 1966), Hecquet and Coupinot (J. Optics/Paris 16, 21, 1985) and Beckers ("Solar and Stellar Granulation", Kluwer, Rutten & Severino Eds, 55, 1988) already discussed the usefulness of image selection, or the "Lucky Observer" mode, for high resolution imaging. All assumed perfect telescope optics. In case of moderate telescope aberrations image selection can still lead to diffraction limited imaging but only when the atmospheric wavefront aberration happens to compensate that of the telescope. In this "Very Lucky Observer" mode the probability of obtaining a good image is reduced over the un-aberrated case, as are the size of the isoplanatic patch and the exposure time. We describe an analysis of these effects for varying telescope aberrations. These result in a strong case for the removal of telescope aberrations either by initial implementation or by the use of slow active optics.

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).

Detailed Study of 4C41.17, the Most Distant Galaxy Cycle 4, Medium. Part i: Early Acquisition Imaging.  

NASA Astrophysics Data System (ADS)

During Cycle 1 we imaged 4C41.17, the most distant galaxy known, with the WFC. Its redshift of 3.8 corresponds to a relative lookback time of ~ 90% and must be close to the epoch at which the galaxies formed. The ultraviolet continuum was detected at high signal to noise. 30% of its flux comes from clumps on the scale of a few hundred parsec. We here propose to carry out an intensive study of this important object with the unaberrated HST using imaging (WFPC2) and spectroscopy (FOS). Our aims are 1) deep continuum imaging to study the morphology of 4C41.17 and possible neighboring cluster galaxies with much better sensitivity and resolution than is possible with our current Cycle 1 images, 2) Ly-a imaging, if possible with the Linear Ramp Filters, to study the Ly-a emission from 4C41.17 and its extensive halo, and 3) FOS spectros- copy of the three brightest clumps to obtain information on the sub- kiloparsec scale about the kinematics and the scale and nature of the absorption clouds which have recently been observed from the ground.

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.

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

Characterizing accuracy of total hemoglobin recovery using contrast-detail analysis in 3D image-guided near infrared spectroscopy with the boundary element method  

PubMed Central

The quantification of total hemoglobin concentration (HbT) obtained from multi-modality image-guided near infrared spectroscopy (IG-NIRS) was characterized using the boundary element method (BEM) for 3D image reconstruction. Multi-modality IG-NIRS systems use a priori information to guide the reconstruction process. While this has been shown to improve resolution, the effect on quantitative accuracy is unclear. Here, through systematic contrast-detail analysis, the fidelity of IG-NIRS in quantifying HbT was examined using 3D simulations. These simulations show that HbT could be recovered for medium sized (20mm in 100mm total diameter) spherical inclusions with an average error of 15%, for the physiologically relevant situation of 2:1 or higher contrast between background and inclusion. Using partial 3D volume meshes to reduce the ill-posed nature of the image reconstruction, inclusions as small as 14mm could be accurately quantified with less than 15% error, for contrasts of 1.5 or higher. This suggests that 3D IG-NIRS provides quantitatively accurate results for sizes seen early in treatment cycle of patients undergoing neoadjuvant chemotherapy when the tumors are larger than 30mm.

Development and applications of an acoustic package for deep-sea sub-bottom profiling and detailed seafloor imaging  

NASA Astrophysics Data System (ADS)

In the deep-sea geological survey, good survey results are difficult to obtain by a conventional surface-towed acoustic survey system, because the horizontal resolution is limited due to the long distance between the sensor and the target (seafloor). In order to improve the horizontal resolution, a deep-tow system, which tows the sensor in the vicinity of seafloor, is most practical, and many such systems have been developed and used until today. It is not easy, however, to carry out a high-density survey in a small area by maneuvering the towing body altitude sufficiently close to the seafloor with rugged topography. A ROV (Remotely Operated Vehicle) can be used to solve this problem. The ROV makes a high-density 2D survey feasible because of its maneuverability, although a long-distance survey is difficult with it. Accordingly, we have developed an acoustic survey system installed on a ROV. The system named DAIPACK (Deep-sea Acoustic Imaging Package) consists of (1) a deep-sea sub-bottom profiler and (2) a deep-sea sidescan sonar. (1) Deep-sea sub-bottom profiler A light-weight and compact sub-bottom profiler for shallow water was chosen to improve and repackage for the deep sea usage. The system is composed of three units; a transducer, an electronic unit and a notebook computer for system control and data acquisition. The source frequency is 10kHz. To convert the system for the deep sea, the transducer was exchanged for the deep sea model, and the electronic unit was improved accordingly. The electronic unit and the notebook computer were installed in a spherical pressure vessel. (2) Deep-sea sidescan sonar We remodeled a compact shallow sea sidescan sonar(water depth limitation is 30m ) into a deep sea one. This sidescan sonar is composed of a sonar towfish (transducers and an electronic unit ), a cable and a notebook computer (data processor). To accommodate in the deep water, the transducers were remodeled into a high pressure resistance type, and the electronic unit and the computer unit were stored in a spherical pressure vessel. The frequency output of the sidescan sonar is 330kHz, and the ranging distance is variable from 15m to 120m (one side).

X-MIME: An Imaging X-ray Spectrometer for Detailed Study of Jupiter's Icy Moons and the Planet's X-ray Aurora  

NASA Technical Reports Server (NTRS)

Remote observations with the Chandra X-ray Observatory and the XMM-Newton Observatory have shown that the Jovian system is a source of x-rays with a rich and complicated structure. The planet's polar auroral zones and its disk are powerful sources of x-ray emission. Chandra observations revealed x-ray emission from the Io Plasma Torus and from the Galilean moons Io, Europa, and possibly Ganymede. The emission from these moons is certainly due to bombardment of their surfaces of highly energetic protons, oxygen and sulfur ions from the region near the Torus exciting atoms in their surfaces and leading to fluorescent x-ray emission lines. Although the x-ray emission from the Galilean moons is faint when observed from Earth orbit, an imaging x-ray spectrometer in orbit around these moons, operating at 200 eV and above with 150 eV energy resolution, would provide a detailed mapping (down to 40 m spatial resolution) of the elemental composition in their surfaces. Such maps would provide important constraints on formation and evolution scenarios for the surfaces of these moons. Here we describe the characteristics of X-MIME, an imaging x-ray spectrometer under going a feasibility study for the JIMO mission, with the ultimate goal of providing unprecedented x-ray studies of the elemental composition of the surfaces of Jupiter's icy moons and Io, as well as of Jupiter's auroral x-ray emission.

The insanity of place.  

PubMed

This paper uses English examples to scrutinize the complex interrelations of insanity and place over the past three centuries, taking as its starting point the late Erving Goffman's paper of the same title. From eighteenth-century Bedlam and the emerging trade in lunacy, through the county asylums and licensed madhouses of the nineteenth century to the return of the the mentally ill to the 'community' in the last half of the twentieth century, the place occupied by insanity has varied sharply, symbolically as well as concretely. These various techniques of containment and damage limitation must be understood as a response to the threats, symbolic and practical, that serious mental illness poses to the social order, at both the micro- and macroscopic levels of analysis.

Academic detailing.  

PubMed

There are a number of sources available to prescribers to stay up to date about medicines. Prescribers in rural areas in developing countries however, may not able to access some of them. Interventions to improve prescribing can be educational, managerial, and regulatory or use a mix of strategies. Detailing by the pharmaceutical industry is widespread. Academic detailing (AD) has been classically seen as a form of continuing medical education in which a trained health professional such as a physician or pharmacist visits physicians in their offices to provide evidence-based information. Face-to-face sessions, preferably on an individual basis, clear educational and behavioural objectives, establishing credibility with respect to objectivity, stimulating physician interaction, use of concise graphic educational materials, highlighting key messages, and when possible, providing positive reinforcement of improved practices in follow-up visits can increase success of AD initiatives. AD is common in developed countries and certain examples have been cited in this review. In developing countries the authors have come across reports of AD in Pakistan, Sudan, Argentina and Uruguay, Bihar state in India, Zambia, Cuba, Indonesia and Mexico.

What place for ?racecadotril?  

PubMed

Worldwide, there are about two billion cases of diarrhoeal disease every year and it is the second leading cause of death in children under 5 years of age, killing 1.5 million children annually.(1) The most severe threat posed by diarrhoea is dehydration. In the UK, the incidence of diarrhoea is about one episode per person per year,(2) and approximately 10% of children younger than 5 years old present to healthcare services with gastroenteritis each year.(3) ?Racecadotril (Hidrasec) is the first in a new class of antidiarrhoeal drug ('enkephalinase inhibitor') that has an antisecretory mechanism and is licensed in adults, children and infants (over 3 months of age) for symptomatic treatment of acute diarrhoea or as complementary treatment when causal treatment is possible.(4-6) Here we review the evidence for racecadotril and its place in the management of acute diarrhoea.

Faraway Places, Fabulous Journeys: Travels on Paper, 1450-1700  

NSDL National Science Digital Library

Using this small web feature from the National Gallery of Art, visitors can closely examine four relatively fragile and little seen works from the Gallery's collections: The Triumph of Dionysus, ca. 1598, an etching by Pierre Brebiette; The Land of Cockaigne, 1564, an etching by Niccol" Nelli; seven scenes from The Journey to Constantinople, published 1553, a woodcut by Pieter Coecke van Aelst; and Etow Oh Koam, King of the River Nation, ca. 1710, a mezzotint by John Simon. What these works have in common (as well as the sixty works on paper on view at the museum thorough September 16, 2007) is that they were created to give Europeans a glimpse of distant and imaginary places, at a time when images were in much shorter supply than at present, and photography did not exist. Each print is presented with numbered details that can be moused over for more information. For example, in the mythical Land of Cockaigne there is a pot on top of a mountain of cinnamon that spews out pasta. It is also possible to zoom in on any of the images, for a close up of additional details, such as the turtle totem of Etow Oh Koam.

A woman's rightful place?  

PubMed

Rural development projects in sub-Saharan Africa tend not to succeed because they do not consider women's role and their significance, even though women constitute 70% of agricultural workers, 80% of food producers, 100% of people who prepare meals, and 60-90% do food marketing. Development specialists ignore women because they are not involved in political activities and in decision making. As long as women and women's contributions are not considered, rural development projects will remain inefficient and development will not take place. Thus, projects must include women as agents and beneficiaries of development in key sectors of the economy. Rural development specialists must also consider the effect male labor emigration has on rural women. For example, drought has forced many men to leave their villages, leaving a work force consisting of 95% women to fight desertification. All too often, women have no or limited land ownership rights, thereby keeping them from improving the land, e.g., planting perennial fruit crops. They also tend to be hired hands rather than food producers. They cannot obtain bank loans because they do not own land, and because they are often illiterate (over 90% female illiteracy in 28 African countries), they can neither understand nor complete bank loan forms. Rural development projects further alienate women by aiming training programs to men or by using male agricultural extension agents. Women react to this alienation by rejecting projects that do not benefit them and follow more profitable activities which sometimes interfere with projects. Thus, rural development programs need to invest in women to ensure viable and efficient sustainable development. PMID:12344988

Detailed imaging of the 2007 Pisco co-seismic and post-seismic deformation - implications on the seismogenic behavior of subduction megathrusts  

NASA Astrophysics Data System (ADS)

In the last couple of decades, advances in the analysis techniques and instrumentation have improved significantly our capability to document the different stages of the seismic cycle, namely the co-, post- and inter-seismic phases. To this respect, the Mw8.0 Pisco, Peru, earthquake of August 2007 is exemplary, with numerous data sets allowing to explore the details of each phase and study their relationship. We derive a kinematic model of the coseismic rupture from the joint non-linear inversion of teleseismic and six Interferometric Synthetic Aperture Radar (InSAR) images. Our preferred model indicates a remarkable anti-correlation between the co-seismic slip distribution and the aftershock distribution determined from the Peruvian seismic network. The proposed source model is compatible with regional run-up measurements and open-ocean tsunami records. In particular, the tsunami observations validate that the rupture did not extend to the trench, and confirm that the Pisco event is not a tsunami earthquake despite its low apparent rupture velocity (< 1.5 km/s). We favor the interpretation that the earthquake consists of 2 subevents, each with a conventional rupture velocity (2-4 km/s). The delay between the 2 subevents might reflect the time for the second shock to nucleate or, alternatively, the time it took for afterslip to increase the stress level on the second asperity to a level necessary for static triggering. The source model predicts uplift offshore and subsidence onland with the pivot line following the changes in curvature of the coastline. This observation set the Pisco earthquake as one of the best examples of a link between the geomorphology of the coastline and the pattern of surface deformation induced by large interplate ruptures. The post-seismic deformation following the mainshock is studied using a local network of continuous GPS stations and the PCAIM inversion method. The inversion indicates that the two patches of co-seismic slip triggered aseismic frictional afterslip on two other adjacent patches. The most prominent of those post-seismic patches coincides with the subducting Nazca ridge, an area also characterized by a locally low interseismic coupling and which seems to have acted as a barrier to seismic rupture propagation repeatedly in the past. The ’seismogenic’ portion of the megathrust thus appears to be paved with interfingering of rate-weakening and rate-strengthening patches. The rate-strengthening patches are shown to contribute to an unsuspectedly high proportion of aseismic slip and to determine the extent and frequency of large interplate earthquakes. Aseismic slip accounts for as much as 50-70% of the slip budget on the seismogenic portion of the megathrust of central Peru and the return period of Mw 8.0 earthquakes in the Pisco area is estimated to 250 years.

Optimal dispersion and central places  

NASA Astrophysics Data System (ADS)

This paper presents research into optimal dispersion models as applied to central places. The literature regarding location optimization and central places is reviewed and the motivation for employing dispersion models is identified. Models that employ the objective of maximal dispersion in the context of central places are formulated and solved in the context of both single- and multiple-good systems. Two methods for generating multiple-good systems are presented: a multiple-type dispersion model and a K-value constraint set formulation. Sequential solutions to dispersion models demonstrate how a system of central places could develop over time. The solutions to these models generate the patterns of central places expected under the organizing principles of central place theory. The objective of maximal dispersion is posited as both a motivating factor in central place location decisions, and as the optimal outcome of a mature system of central places.

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.

Detailed Study of 4C41.17, the Most Distant Galaxy - Lrf Portion Cycle 4, Medium. Part i: Early Acquisition Imaging.  

NASA Astrophysics Data System (ADS)

During Cycle 1 we imaged 4C41.17, the most distant galaxy known, with the WFC. Its redshift of 3.8 corresponds to a relative lookback time of ~ 90% and must be close to the epoch at which the galaxies formed. The ultraviolet continuum was detected at high signal to noise. 30% of its flux comes from clumps on the scale of a few hundred parsec. We here propose to carry out an intensive study of this important object with the unaberrated HST using imaging (WFPC2) and spectroscopy (FOS). Our aims are 1) deep continuum imaging to study the morphology of 4C41.17 and possible neighboring cluster galaxies with much better sensitivity and resolution than is possible with our current Cycle 1 images, 2) Ly-a imaging, if possible with the Linear Ramp Filters, to study the Ly-a emission from 4C41.17 and its extensive halo, and 3) FOS spectros- copy of the three brightest clumps to obtain information on the sub- kiloparsec scale about the kinematics and the scale and nature of the absorption clouds which have recently been observed from the ground.

A large 3D target with small inner details: A difficult cocktail for imaging purposes without a priori knowledge on the scatterers geometry  

NASA Astrophysics Data System (ADS)

To accurately image a complex shape but large 3D target whose scattered field has been measured in an anechoic environment at high frequencies (18 and 20 GHz), we have developed a complete imaging process, combining experimental and numerical works. The adopted strategy exploits the maximum of available information related to the measurements, both in terms of quantity and accuracy without any a priori knowledge on the scatterer geometry. We first determine the position and then the dimension of the spatial domain which contains the target. This localization is realized directly from the analysis of the spectrum of the measured fields taking into account the random noise disturbing the measurement points. Then, we construct a quantitative permittivity map of this investigation domain thanks to an iterative inversion procedure based on a Bayesian formulation where the spatial diversity of the real random noise is adequately exploited. By following this strategy, we have been able to quantitatively retrieve the target both in terms of dimension, shape and electromagnetic properties, even with a very limited number of measurement points and for a single polarization case. With such a process, even spheres with a diameter equal to ?/3 are correctly reconstructed at 20 GHz.

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.

A Detailed Gravitational Lens Model Based on Submillimeter Array and Keck Adaptive Optics Imaging of a Herschel-ATLAS Submillimeter Galaxy at z = 4.243  

NASA Astrophysics Data System (ADS)

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.

We measure a half-light radius of the background source of r{sub s} = 4.4 {+-} 0.5 kpc which implies an IR luminosity surface density of {Sigma}{sub IR} (3.4 {+-} 0.9) Multiplication-Sign 10{sup 11} L{sub Sun} kpc{sup -2}, a value that is typical of z > 2 SMGs but significantly lower than IR luminous galaxies at z {approx} 0. The two lens galaxies are compact (r{sub lens} Almost-Equal-To 0.9 kpc) early-types with Einstein radii of {theta}{sub E1} 0.57 {+-} 0.01 and {theta}{sub E2} = 0.40 {+-} 0.01 that imply masses of M{sub lens1} = (7.4 {+-} 0.5) Multiplication-Sign 10{sup 10} M{sub Sun} and M{sub lens2} = (3.7 {+-} 0.3) Multiplication-Sign 10{sup 10} M{sub Sun }. 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 {approx} 0.6. This work highlights the importance of high spatial resolution imaging in developing models of strongly lensed galaxies discovered by Herschel.

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.

It's time for a crisper image of the Face of the Earth: Landsat and climate time series for massive land cover & climate change mapping at detailed resolution.  

NASA Astrophysics Data System (ADS)

Combining climate dynamics and land cover at a relative coarse resolution allows a very interesting approach to global studies, because in many cases these studies are based on a quite high temporal resolution, but they may be limited in large areas like the Mediterranean. However, the current availability of long time series of Landsat imagery and spatially detailed surface climate models allow thinking on global databases improving the results of mapping in areas with a complex history of landscape dynamics, characterized by fragmentation, or areas where relief creates intricate climate patterns that can be hardly monitored or modeled at coarse spatial resolutions. DinaCliVe (supported by the Spanish Government and ERDF, and by the Catalan Government, under grants CGL2012-33927 and SGR2009-1511) is the name of the project that aims analyzing land cover and land use dynamics as well as vegetation stress, with a particular emphasis on droughts, and the role that climate variation may have had in such phenomena. To meet this objective is proposed to design a massive database from long time series of Landsat land cover products (grouped in quinquennia) and monthly climate records (in situ climate data) for the Iberian Peninsula (582,000 km2). The whole area encompasses 47 Landsat WRS2 scenes (Landsat 4 to 8 missions, from path 197 to 202 and from rows 30 to 34), and 52 Landsat WRS1 scenes (for the previous Landsat missions, 212 to 221 and 30 to 34). Therefore, a mean of 49.5 Landsat scenes, 8 quinquennia per scene and a about 6 dates per quinquennium , from 1975 to present, produces around 2376 sets resulting in 30 m x 30 m spatial resolution maps. Each set is composed by highly coherent geometric and radiometric multispectral and multitemporal (to account for phenology) imagery as well as vegetation and wetness indexes, and several derived topographic information (about 10 Tbyte of data). Furthermore, on the basis on a previous work: the Digital Climatic Atlas of the Iberian Peninsula, spatio-temporal surface climate data has been generated with a monthly resolution (from January 1950 to December 2010) through a multiple regression model and residuals spatial interpolation using geographic variables (altitude, latitude and continentality) and solar radiation (only in the case of temperatures). This database includes precipitation, mean minimum and mean maximum air temperature and mean air temperature, improving the previous one by using the ASTER GDEM at 30 m spatial resolution, by deepening to a monthly resolution and by increasing the number of meteorological stations used, representing a total amount of 0.7 Tbyte of data. An initial validation shows accuracies higher than 85 % for land cover maps and an RMS of 1.2 ºC, 1.6 ºC and 22 mm for mean and extreme temperatures, and for precipitation, respectively. This amount of new detailed data for the Iberian Peninsula framework will be used to study the spatial direction, velocity and acceleration of the tendencies related to climate change, land cover and tree line dynamics. A global analysis using all these datasets will try to discriminate the climatic signal when interpreted together with anthropogenic driving forces. Ultimately, getting ready for massive database computation and analysis will improve predictions for global models that will require of the growing high-resolution information available.

The nature of the ocean-continent transition on the Newfoundland rifted margin: Results from detailed tomographic imaging of the crust  

NASA Astrophysics Data System (ADS)

The crustal structure of rifted margins holds important clues to the mode of extension and break-up before ocean-spreading commenced. The transition from thinned continental crust to normal oceanic crust (OCT) occurs over 50-150 km on most nonvolcanic rifted margins, and recent seismic studies on the Iberian and Newfoundland margins have shown that the nature of the OCT can vary over short (~100 km) distances along the strike of the margin, and large differences have also been noted between conjugate margin pairs. Some OCTs show seismic velocities near the Moho of 7.1 to 7.4 km/s that have been attributed to magmatic underplating and subcrustal serpentinization, but these intermediate velocities appear absent on others. The fitting of the Grand Banks and Iberian margins (Shillington et al., this meeting) illustrates that this complexity can be explained by asymmetric rifting once the crustal structure has been determined with sufficient detail. However, it can be difficult to distinguish between the seismic velocity structure of thinned continental crust and newly formed oceanic crust even with great quality seismic refraction and reflection data. We illustrate the slight variation in P-wave velocity across the OCT in the middle of three seismic refraction/reflection transects that were collected offshore Newfoundland during the SCREECH experiment in the summer of 2000. Given the importance of small scale variations of <0.2 km/s in crust with P velocity of ~6.2 km/s it becomes increasingly more important to provide good error bounds with the tomographic inversions that produce these results.

Polarimetric imaging of the Galactic center at 12.4 microns - The detailed magnetic field structure in the northern arm and the east-west bar  

NASA Technical Reports Server (NTRS)

Recent closely sampled imaging polarimetry of the central 0.5 pc of the Galaxy at 12.4 microns with a 58 x 62 array camera system is presented. The results clearly show that the magnetic field is a property of the diffuse material of the large-scale structures in Sgr A (the northern arm and east-west bar) rather than the embedded sources. The magnetic field is independent of the changes of density and temperature in the compact source environments. The magnetic field direction in much of the east-west bar is complex, and its polarization is probably the result of the superposition of differently oriented filaments. The abrupt decrease of polarization southwest of IRS 1 observed previously is confirmed and shown to reverse sign. This is due either to a rapid change of magnetic field direction close to the dynamical center, or to the superposition of nearly orthogonal fields. The field direction changes smoothly across IRS 1, and no discontinuity of motion here is found.

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.

The question that the title of this lecture poses must depend considerably on the attitude of physicians and surgeons. I have indicated the very low position diagnostic radiology holds in this country relative to our peers in medicine elsewhere. If its improvement is considered to be warranted, we must: (1) Interest medical students at the beginning of their career. (2) Bear in mind that radiologists are likely to be able to teach some anatomy but the reciprocal seldom applies. (3) Obtain chairs in radiology, which are desperately needed. (4) Obtain the acceptance by the medical establishment of the proper place of radiology in clinical medicine. (5) See to the reduction in numbers of unnecessary x-ray examinations.

Melatonin: new places in therapy.  

PubMed

The fact that the full extent of the function of the pineal gland has not yet been elucidated, has stimulated melatonin research worldwide. This review introduces melatonin's mechanism of action, direct and indirect antioxidant actions as well as the antioxidant properties of its metabolites, 6-hydroxymelatonin (6-OHM) and N-acetyl-N-formyl-5-methoxykynurenamine (AFMK). At present the mechanism of action is proposed to be receptor-, protein- and nonprotein-mediated. From its popular role in the treatment of jetlag, melatonin is now implicated in the reduction of oxidative stess, both as a free radical scavenger and antioxidant. Melatonin's direct scavenging action in respect of the following will be discussed: superoxide anions, hydrogen peroxide, hydroxyl radicals, singlet oxygen, peroxy radicals and nitric oxide/peroxy nitrite anions. In addition melatonin also possesses indirect antioxidant activity and the role of its metabolites, AFMK and 6-OHM will be presented. It is these free radical scavenging and antioxidant properties of melatonin that has shifted the focus from that of merely strengthening circadian rhythms to that of neuroprotectant: a new place in therapy.

Color Image Segmentation in a Quaternion Framework  

PubMed Central

In this paper, we present a feature/detail preserving color image segmentation framework using Hamiltonian quaternions. First, we introduce a novel Quaternionic Gabor Filter (QGF) which can combine the color channels and the orientations in the image plane. Using the QGFs, we extract the local orientation information in the color images. Second, in order to model this derived orientation information, we propose a continuous mixture of appropriate hypercomplex exponential basis functions. We derive a closed form solution for this continuous mixture model. This analytic solution is in the form of a spatially varying kernel which, when convolved with the signed distance function of an evolving contour (placed in the color image), yields a detail preserving segmentation.

Contrast-detail phantom scoring methodology.  

PubMed

Published results of medical imaging studies which make use of contrast detail mammography (CDMAM) phantom images for analysis are difficult to compare since data are often not analyzed in the same way. In order to address this situation, the concept of ideal contrast detail curves is suggested. The ideal contrast detail curves are constructed based on the requirement of having the same product of the diameter and contrast (disk thickness) of the minimal correctly determined object for every row of the CDMAM phantom image. A correlation and comparison of five different quality parameters of the CDMAM phantom image determined for obtained ideal contrast detail curves is performed. The image quality parameters compared include: (1) contrast detail curve--a graph correlation between "minimal correct reading" diameter and disk thickness; (2) correct observation ratio--the ratio of the number of correctly identified objects to the actual total number of objects multiplied by 100; (3) image quality figure--the sum of the product of the diameter of the smallest scored object and its relative contrast; (4) figure-of-merit--the zero disk diameter value obtained from extrapolation of the contrast detail curve to the origin (e.g., zero disk diameter); and (5) k-factor--the product of the thickness and the diameter of the smallest correctly identified disks. The analysis carried out showed the existence of a nonlinear relationship between the above parameters, which means that use of different parameters of CDMAM image quality potentially can cause different conclusions about changes in image quality. Construction of the ideal contrast detail curves for CDMAM phantom is an attempt to determine the quantitative limits of the CDMAM phantom as employed for image quality evaluation. These limits are determined by the relationship between certain parameters of a digital mammography system and the set of the gold disks sizes in the CDMAM phantom. Recommendations are made on selections of CDMAM phantom regions which should be used for scoring at different image quality and which scoring methodology may be most appropriate. Special attention is also paid to the use of the CDMAM phantom for image quality assessment of digital mammography systems particularly in the vicinity of the Nyquist frequency. PMID:15839353

Transforming Mount Airy into Mayberry: Film-Induced Tourism as Place-Making  

Microsoft Academic Search

Film-induced tourism is increasingly popular in the United States and globally. Scholars have tended to emphasize the effect of movies and television in forming the image of tourist destinations and thus influencing traveler motivation and experience. In this article, we shift discussion of film tourism beyond simply place image formation to consider it in the broader context of place-making. Such

Cultural festivals are often planned as part of place marketing, image branding, and civic boosterism to aid in the regeneration of urban areas. While complexities surrounding place, marketing, and festivals have been acknowledged with regard to large scale events, little is known about ethnic festivals in urban neighborhoods. It is important to understand festival places and the factors that challenge

Cardiac Imaging System  

NASA Technical Reports Server (NTRS)

Although not available to all patients with narrowed arteries, balloon angioplasty has expanded dramatically since its introduction with an estimated further growth to 562,000 procedures in the U.S. alone by 1992. Growth has fueled demand for higher quality imaging systems that allow the cardiologist to be more accurate and increase the chances of a successful procedure. A major advance is the Digital Cardiac Imaging (DCI) System designed by Philips Medical Systems International, Best, The Netherlands and marketed in the U.S. by Philips Medical Systems North America Company. The key benefit is significantly improved real-time imaging and the ability to employ image enhancement techniques to bring out added details. Using a cordless control unit, the cardiologist can manipulate images to make immediate assessment, compare live x-ray and roadmap images by placing them side-by-side on monitor screens, or compare pre-procedure and post procedure conditions. The Philips DCI improves the cardiologist's precision by expanding the information available to him.

Eros details enhanced by computer processing  

NASA Technical Reports Server (NTRS)

The NEAR camera's ability to show details of Eros's surface is limited by the spacecraft's distance from the asteroid. That is, the closer the spacecraft is to the surface, the more that details are visible. However mission scientists regularly use computer processing to squeeze an extra measure of information from returned data. In a technique known as 'superresolution', many images of the same scene acquired at very, very slightly different camera pointing are carefully overlain and processed to bright out details even smaller than would normally be visible. In this rendition constructed out of 20 image frames acquired Feb. 12, 2000, the images have first been enhanced ('high-pass filtered') to accentuate small-scale details. Superresolution was then used to bring out features below the normal ability of the camera to resolve.

Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR was the first spacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions. See the NEAR web page at http://near.jhuapl.edu for more details.

Noise-resistant structure-preserving multiscale image decomposition  

NASA Astrophysics Data System (ADS)

A challenge for current edge-preserving image decompositions is to deal with noisy images. Gradient- or magnitude difference-based techniques regard the noise boundary as edges, while the local extrema-based method suffers from averaging noisy envelops. We introduce local anisotropy derived from nonlinear local structure tensor to differentiate edges from fine-scale details and noises. Providing low smoothness weights to the places with large local anisotropy rather than a large gradient under the improved weighted least squares optimization framework, we present a noise-resistant, structure-preserving smoothing operator. By either progressively or recursively applying this operator we construct our structure-preserving multiscale image decomposition. Based on the key property of our algorithm, noise resistance, we compare our results with existing edge-preserving image decomposition methods and demonstrate the effectiveness and robustness of our structure-preserving decompositions in the context of image restoration, noisy image abstraction, and noisy image dehazing.

Category-selective neural substrates for person- and place-related concepts.  

PubMed

The influence of object-category on the representation of semantic knowledge remains unresolved. We present a functional magnetic resonance imaging study that investigates whether there are distinct neural substrates for semantic knowledge of kinds of people (e.g., lawyer, nurse etc.) and places (e.g., bank, prison etc.). Access to semantic details about kinds of people produced selective responses in the precuneus, medial prefrontal cortex, left anterior temporal lobe, posterior middle temporal gyrus and the temporoparietal junction. Corresponding place-selective responses were present in the parahippocampal gyrus and retrosplenial complex. Category selectivity was found to be less pronounced when conceptual information was accessed about kinds of people compared to unique people (e.g., Obama). We attribute this to the greater importance of cross-categorical semantic knowledge in the conceptual representation of kinds. Together, these results show the importance of object-category in non-perceptual semantic representations and indicate the manner in which these systems may interact to create full conceptual representations.

Photothermal imaging  

NASA Astrophysics Data System (ADS)

An automated image analysis system with two imaging regimes is described. Photothermal (PT) effect is used for imaging of a temperature field or absorption structure of the sample (the cell) with high sensitivity and spatial resolution. In a cell study PT-technique enables imaging of live non-stained cells, and the monitoring of the cell shape/structure. The system includes a dual laser illumination unit coupled to a conventional optical microscope. A sample chamber provides automated or manual loading of up to 3 samples and cell positioning. For image detection a 256 X 256 10-bit CCD-camera is used. The lasers, scanning stage, and camera are controlled by PC. The system provides optical (transmitted light) image, probe laser optical image, and PT-image acquisition. Operation rate is 1 - 1.5 sec per cell for a cycle: cell positioning -- 3 images acquisition -- image parameters calculation. A special database provides image/parameters storage, presentation, and cell diagnostic according to quantitative image parameters. The described system has been tested during live and stained blood cell studies. PT-images of the cells have been used for cell differentiation. In experiments with the red blood cells (RBC) that originate from normal and anaemia blood parameters for disease differentiation have been found. For white blood cells in PT-images the details of cell structure have found that absent in their optical images.

Since biomarker imaging is traditionally understood as imaging of molecular probes, we highly recommend to avoid any confusion with the previously defined term “imaging biomarkers” and, therefore, only use “molecular probe imaging (MPI)” in that context. Molecular probes (MPs) comprise all kinds of molecules administered to an organism which inherently carry a signalling moiety. This review highlights the basic concepts and differences of molecular probe imaging using specific biomarkers. In particular, PET radiopharmaceuticals are discussed in more detail. Specific radiochemical and radiopharmacological aspects as well as some legal issues are presented.

Ecotourism and commodification: protecting people and places  

Microsoft Academic Search

The ability of ecotourism to protect both people and places is an unresolved, and growing, concern. Commodification of host culture and environment is a widely reported social impact of tourism and spawns an array of implications regarding indigenous people's view of their places and themselves. The degree of impact from ecotourism development is related to the degree of market development

Detailed Debunking of Denial  

NASA Astrophysics Data System (ADS)

The disinformation campaign against climate science has been compared to a guerilla war whose tactics undermine the traditional checks and balances of science. One comprehensive approach has to been produce archives of generic responses such as the websites of RealClimate and SkepticalScience. We review our experiences with an alternative approach of detailed responses to a small number of high profile cases. Our particular examples were Professor Ian Plimer and Christopher Monckton, the Third Viscount Monckton of Brenchley, each of whom has been taken seriously by political leaders in our respective countries. We relate our experiences to comparable examples such as John Mashey's analysis of the Wegman report and the formal complaints about Lomborg's "Skeptical Environmentalist" and Durkin's "Great Global Warming Swindle". Our two approaches used contrasting approaches: an on-line video of a lecture vs an evolving compendium of misrepresentations. Additionally our approaches differed in the emphasis. The analysis of Monckton concentrated on the misrepresentation of the science, while the analysis of Plimer concentrated on departures from accepted scientific practice: fabrication of data, misrepresentation of cited sources and unattributed use of the work of others. Benefits of an evolving compendium were the ability to incorporate contributions from members of the public who had identified additional errors and the scope for addressing new aspects as they came to public attention. `Detailed debunking' gives non-specialists a reference point for distinguishing non-science when engaging in public debate.

Comment: Detailed balance revisited.  

PubMed

The concept of detailed balance is central to the field of chemical kinetics and provides important constraints on relationships between equilibrium and rate constants. Miller et al. [Phys. Chem. Chem. Phys., 2009, 11, 1128] have recently proposed that having the ratio of forward and reverse rate constants equal to the equilibrium constant--a relationship they equate with detailed balance--is a sufficient condition to guarantee that a chemical system eventually relaxes to equilibrium. This assertion is true, however, only for an isolated system. In a closed system, where energy exchange between the system and the environment occurs, input of energy in the form of an externally driven oscillation of a thermodynamic parameter (e.g. pressure or electric field strength), can maintain a chemical system in a stationary state away from equilibrium even if the ratio of the forward and backward rate constants for each elementary reaction equals the equilibrium constant at every instant. This fact allows appropriately designed molecules to serve as free-energy transducers and molecular machines. PMID:19830346

Gallbladder imaging.  

PubMed

The treatment of gallbladder disease has been revolutionized by improvements in laparoscopic surgery as well as endoscopic and radiologic interventional techniques. Therapeutic success is dependent on accurate radiologic assessment of gallbladder pathology. This article describes recent technical advances in ultrasonography, multidetector computed tomography, magnetic resonance imaging, positron emission tomography, and scintigraphy, which have significantly improved the accuracy of noninvasive imaging of benign and malignant gallbladder disease. The imaging findings of common gallbladder disorders are presented, and the role of each of the imaging modalities is placed in perspective for optimizing patient management. PMID:20478486

Detailing the human tail.  

PubMed

There have been 23 true vestigial tails reported in the literature since 1884. A new case is described, and its magnetic resonance imaging and pathological features are presented. A review of the literature and analysis of the pathological characteristics reveal that the vestigial human tail may be associated with other abnormalities. Vestigial tails contain adipose and connective tissue, blood vessels, and nerves and are covered by skin. Bone, cartilage, notochord, and spinal cord elements are lacking. Tails are easily removed surgically without residual effects. Since 29% (7 of 24) of the reported tails have been associated with other malformations, careful clinical evaluation of these patients is recommended. PMID:3284435

Image-based streamline generation and rendering.  

PubMed

Seeding streamlines in 3D flow fields without considering their projections in screen space can produce visually cluttered rendering results. Streamlines will overlap or intersect with each other in the output image, which makes it difficult for the user to perceive the underlying flow structure. This paper presents a method to control the seeding and generation of streamlines in image space to avoid visual cluttering and allow a more flexible exploration of flow fields. In our algorithm, 2D images with depth maps generated by a variety of visualization techniques can be used as input from which seeds are placed and streamlines are generated. The density and rendering styles of streamlines can be flexibly controlled based on various criteria to improve visual clarity. With our image space approach, it is straightforward to implement the level of detail rendering, depth peeling, and stylized rendering of streamlines to allow for more effective visualization of 3D flow fields.

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.

Library of Congress: Places in History  

NSDL National Science Digital Library

What do Missouri and Virginia have in common? They are both two of the places profiled on the Library of Congress' "Places in History" site. This remarkable site brings together maps and other primary documents to profile interesting places across the broad span of American history. Currently, there are six entries, including First Battle of Bull Run, Rich Mountain and Vicinity, and Gulf Coast. This last feature is a great place to begin, as it includes several key maps and charts that document the Gulf Coast in Florida around the beginning of the Civil War. Along with these items, there is a listing of related resources at the Library. Visitors shouldn't miss the Extra Session of Congress area as it provides some great historical background on the extra session of Congress called by President Abraham Lincoln for July 4, 1861 that would discuss the Civil War.

Influences on physicians' adoption of electronic detailing (e-detailing).  

PubMed

E-detailing means using digital technology: internet, video conferencing and interactive voice response. There are two types of e-detailing: interactive (virtual) and video. Currently, little is known about what factors influence physicians' adoption of e-detailing. The objectives of this study were to test a model of physicians' adoption of e-detailing and to describe physicians using e-detailing. A mail survey was sent to a random sample of 2000 physicians practicing in Iowa. Binomial logistic regression was used to test the model of influences on physician adoption of e-detailing. On the basis of Rogers' model of adoption, the independent variables included relative advantage, compatibility, complexity, peer influence, attitudes, years in practice, presence of restrictive access to traditional detailing, type of specialty, academic affiliation, type of practice setting and control variables. A total of 671 responses were received giving a response rate of 34.7%. A total of 141 physicians (21.0%) reported using of e-detailing. The overall adoption model for using either type of e-detailing was found to be significant. Relative advantage, peer influence, attitudes, type of specialty, presence of restrictive access and years of practice had significant influences on physician adoption of e-detailing. The model of adoption of innovation is useful to explain physicians' adoption of e-detailing. PMID:19306198

Cure-in-place process for seals  

DOEpatents

A cure-in-place process which allows a rubber seal element to be deformed to its service configuration before it is cross-linked and, hence, is a plastic and does not build up internal stress as a result of the deformation. This provides maximum residual strength to resist the differential pressure. Furthermore, the process allows use of high modulus formulations of the rubber seal element which would otherwise crack if cured and then deformed to its service configuration, resulting in a seal which has better gap bridging capability. Basically, the process involves positioning an uncured seal element in place, deforming it to its service configuration, heating the seal element, curing it in place, and then fully seating the seal.

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

Hubble Space Telescope Image  

NASA Technical Reports Server (NTRS)

A comparison image of the M100 Galactic Nucleus, taken by the Hubble Space Telescope (HST) Wide Field Planetary Camera-1 (WF/PC1) and Wide Field Planetary Camera-2 (WF/PC2). The HST was placed in a low-Earth orbit by the Space Shuttle Discovery, STS-31 mission, in April 1990. Two months after its deployment in space, scientists detected a 2-micron spherical aberration in the primary mirror of the HST that affected the telescope's ability to focus faint light sources into a precise point. This imperfection was very slight, one-fiftieth of the width of a human hair. During four spacewalks, the STS-61 crew replaced the solar panel with its flexing problems; the WF/PC1 with the WF/PC2, with built-in corrective optics; and the High-Speed Photometer with the Corrective Optics Space Telescope Axial Replacement (COSTAR), to correct the aberration for the remaining instruments. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit for 15 years or more. The HST provides fine detail imaging, produces ultraviolet images and spectra, and detects very faint objects.

Barriers to aging in place include physical mobility and transportation limitations, isolation related loneliness and depression, diminishing health status, housing quality, finances, and caregiving resources. The scope of the aging demographic shift, economic consequences and loss of quality of life urge adoption of such successful approaches as the life course model. Desirable aging in place provides person-centered quality of living that is independence-effective and affordable. Systematic community-centered and person-centered approaches are crucial to accomplishing the central actions of the life course model. Not only are the actions necessary, they are interactive, interdependent, and strategic in supporting one another. PMID:24846462

An automated digital imaging system for environmental monitoring applications  

USGS Publications Warehouse

Recent improvements in the affordability and availability of high-resolution digital cameras, data loggers, embedded computers, and radio/cellular modems have advanced the development of sophisticated automated systems for remote imaging. Researchers have successfully placed and operated automated digital cameras in remote locations and in extremes of temperature and humidity, ranging from the islands of the South Pacific to the Mojave Desert and the Grand Canyon. With the integration of environmental sensors, these automated systems are able to respond to local conditions and modify their imaging regimes as needed. In this report we describe in detail the design of one type of automated imaging system developed by our group. It is easily replicated, low-cost, highly robust, and is a stand-alone automated camera designed to be placed in remote locations, without wireless connectivity.

2-D Drift Velocities from the IMAGE EUV Plasmaspheric Imager  

NASA Technical Reports Server (NTRS)

The IMAGE Mission extreme ultraviolet imager (EUY) observes He+ plasmaspheric ions throughout the inner magnetosphere. Limited by ionizing radiation and viewing close to the Sun, images of the He+ distribution are available every 10 minutes for many hours as the spacecraft passes through apogee in its highly elliptical orbit. As a consistent constituent at about 15%, He+ is an excellent surrogate for monitoring all of the processes that control the dynamics of plasmaspheric plasma. In particular, the motion ofHe+ transverse to the ambient magnetic field is a direct indication of convective electric fields. The analysis of boundary motions has already achieved new insights into the electrodynamic coupling processes taking place between energetic magnetospheric plasmas and the ionosphere. Yet to be fulfilled, however, is the original promise that global EUY images of the plasmasphere might yield two-dimensional pictures of meso-scale to macro-scale electric fields in the inner magnetosphere. This work details the technique and initial application of an IMAGE EUY analysis that appears capable of following thermal plasma motion on a global basis.

Simulation of imaging and refocusing for light field photography  

NASA Astrophysics Data System (ADS)

The entire process of image formation and refocusing of light field photography with microlens array is simulated using the in-house software OTS based on real ray tracing. The optical system consists of a photographic lens and the microlens array which are specifically designed. Objects are placed in different distance before the lens, and images of them on the detector plane are got by imaging simulation algorithm. Utilizing the color, intensity and the corresponding direction information of light rays on the image plane, pictures focusing at different depth in the image space are calculated, so that we can refocus at different objects in different distance. The paper also details the basic requirement of optical system and this simulation process is a fundamental work of research on design method and performance of lens using in light field photography.

Place-pitch manipulations with cochlear implants  

PubMed Central

Pitch can be conveyed to cochlear implant (CI) listeners via both place of excitation and temporal cues. The transmission of place cues may be hampered by several factors including limitations on the insertion depth and number of implanted electrodes, and the broad current spread produced by monopolar stimulation. The following series of experiments investigate several methods to partially overcome these limitations. Experiment 1 compares two recently published techniques that aim to activate more apical fibers than produced by monopolar or bipolar stimulation of the most apical contacts. The first technique (phantom stimulation) manipulates the current spread by simultaneously stimulating two electrodes with opposite-polarity pulses of different amplitudes. The second technique manipulates the neural spread of excitation by using asymmetric pulses and exploiting the polarity-sensitive properties of auditory nerve fibers. The two techniques yielded similar results and were shown to produce lower place pitch percepts than stimulation of monopolar and bipolar symmetric pulses. Furthermore, combining these two techniques may be advantageous in a clinical setting. Experiment 2 proposes a novel method to create place pitches intermediate to those produced by physical electrodes by using charge-balanced asymmetric pulses in bipolar mode with different degrees of asymmetry.

Radar Image, Hokkaido, Japan  

NASA Technical Reports Server (NTRS)

The southeast part of the island of Hokkaido, Japan, is an area dominated by volcanoes and volcanic caldera. The active Usu Volcano is at the lower right edge of the circular Lake Toya-Ko and near the center of the image. The prominent cone above and to the left of the lake is Yotei Volcano with its summit crater. The city of Sapporo lies at the base of the mountains at the top of the image and the town of Yoichi -- the hometown of SRTM astronaut Mamoru Mohri -- is at the upper left edge. The bay of Uchiura-Wan takes up the lower center of the image. In this image, color represents elevation, from blue at the lowest elevations to white at the highest. The radar image has been overlaid to provide more details of the terrain. Due to a processing problem, an island in the center of this crater lake is missing and will be properly placed when further SRTM swaths are processed. The horizontal banding in this image is a processing artifact that will be removed when the navigation information collected by SRTM is fully calibrated. This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. Size: 100 by 150 kilometers (62 by 93 miles) Location: 42.5 deg.

Burial at Srebrenica: linking place and trauma.  

PubMed

Five years after the massacre at Srebrenica in Bosnia-Herzegovina, survivors were faced with the decision: where did they want their loved ones buried? This report explores the reasons for their choice in qualitative interviews with 37 survivors of the massacre and 22 key informants performed over the summer 2000. Survivors wanted the loved ones buried at Potocari, a site just outside of Srebrenica, because it represented the site of ultimate horror, was connected to their sense of home, and underscored the various power relationships. The data points to the importance of place for health. Trauma, as it occurs in particular locations, breaks the sense of attachment to a particular place. Restoring the physical and social environment through burial and memorials mitigates the consequences of the trauma. The burial at Potocari provides a window into the mourning, politics, and recovery after mass violence. PMID:12560012

IMAGES, IMAGES, IMAGES  

SciTech Connect

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. The results of an interdisciplinary collaboration are demonstrated in a product for visualizing complex information about global energy interdependence. An invited panel will respond to the presentation.

Exercise-induced pulmonary haemorrhage in the horse: results of a detailed clinical, post mortem and imaging study. IV. Changes in the bronchial circulation demonstrated by C.T. scanning and microradiography.  

PubMed

The purpose of this study was to use radiographic contrast techniques and special imaging methods to identify and high-light bronchial arterial involvement in lung lesions associated with exercise-induced pulmonary haemorrhage (EIPH) in horses. The lungs from four horses with histories of EIPH were prepared for computerised tomographic scanning and microradiography by perfusing the broncho-oesophageal artery with a mixture of red latex and either barium or iodine contrast materials while the pulmonary supply received only blue latex. Computerised tomographic scan slices of the prepared inflated lungs were obtained from the caudal tip of the lung to the hilus. Microradiography of selected lung slices was also performed on a Faxitron. Diffuse areas of increased density, with preferential bronchial arterial supply noted on the computerised tomographic scans were confirmed by microradiography. Dense focal and diffuse plexuses of markedly hypertrophied and highly branched bronchial arterial networks were identified, centred around certain small airways. The vascular supply to these plexuses was recruited predominantly from neighbouring bronchial vessels, and in some cases, from the enlarged vasa vasorum of pulmonary arteries sending anastomoses to the affected areas. The authors conclude that bronchial vascular lesions in EIPH cases are the likely origin of haemorrhage; that small airway disease is the probable initiating stimulus for bronchial vascular proliferation in these lesions; and that the morphology and nature of the neovascular tissue in these lesions provides the conditions leading to haemorrhage in the lungs of horses with EIPH.

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.

The place and time of drugs.  

PubMed

'Context' is one of the most enduring analytical devices in social science accounts of alcohol and other drug (AOD) use, although its elaboration tends to emphasise macro-structural processes (like economic change, law enforcement, health policy, racism or stigma) at the expense of more finely-grained understandings of the place and time of consumption. Drawing on Gilles Deleuze's notion of the assemblage, and its reception in recent critical geographies of AOD use, I will characterise context as an assemblage of social, affective and material forces. Such a characterisation is not indifferent to the range of structural forces that are often understood to mediate AOD use. Rather, it is concerned to document how these forces actually participate in the modulations of consumption. The assemblage will thus be construed in ways that align context with the 'real conditions' (place and time) of drug use. I will develop this argument by way of a case study drawn from a recent qualitative study of the social contexts of methamphetamine use in Melbourne. My goal is to document the ways 'context' is produced in the activity of drug use, and how 'context' so constructed, comes to modulate this use. By contrasting traditional approaches to the analysis of context with methods borrowed from Deleuze, I aim to transcend structural understandings of context in order to clarify the active, local and contingent role of contexts in the mediation of what bodies do 'on' and 'with' drugs.

A Novel Approach for Detail-Enhanced Exposure Fusion Using Guided Filter  

PubMed Central

In this paper we propose a novel detail-enhancing exposure fusion approach using nonlinear translation-variant filter (NTF). With the captured Standard Dynamic Range (SDR) images under different exposure settings, first the fine details are extracted based on guided filter. Next, the base layers (i.e., images obtained from NTF) across all input images are fused using multiresolution pyramid. Exposure, contrast, and saturation measures are considered to generate a mask that guides the fusion process of the base layers. Finally, the fused base layer is combined with the extracted fine details to obtain detail-enhanced fused image. The goal is to preserve details in both very dark and extremely bright regions without High Dynamic Range Image (HDRI) representation and tone mapping step. Moreover, we have demonstrated that the proposed method is also suitable for the multifocus image fusion without introducing artifacts.

A Multiresolution Image Cache for Volume Rendering  

SciTech Connect

The authors discuss the techniques and implementation details of the shared-memory image caching system for volume visualization and iso-surface rendering. One of the goals of the system is to decouple image generation from image display. This is done by maintaining a set of impostors for interactive display while the production of the impostor imagery is performed by a set of parallel, background processes. The system introduces a caching basis that is free of the gap/overlap artifacts of earlier caching techniques. instead of placing impostors at fixed, pre-defined positions in world space, the technique is to adaptively place impostors relative to the camera viewpoint. The positions translate with the camera but stay aligned to the data; i.e., the positions translate, but do not rotate, with the camera. The viewing transformation is factored into a translation transformation and a rotation transformation. The impostor imagery is generated using just the translation transformation and visible impostors are displayed using just the rotation transformation. Displayed image quality is improved by increasing the number of impostors and the frequency that impostors are re-rendering is improved by decreasing the number of impostors.

Motor neurons and the sense of place.  

PubMed

Seventy years ago George Romanes began to document the anatomical organization of the spinal motor system, uncovering a multilayered topographic plan that links the clustering and settling position of motor neurons to the spatial arrangement and biomechanical features of limb muscles. To this day, these findings have provided a structural foundation for analysis of the neural control of movement and serve as a guide for studies to explore mechanisms that direct the wiring of spinal motor circuits. In this brief essay we outline the core of Romanes's findings and place them in the context of recent studies that begin to provide insight into molecular programs that assign motor pool position and to resolve how motor neuron position shapes circuit assembly. Romanes's findings reveal how and why neuronal positioning contributes to sensory-motor connectivity and may have relevance to circuit organization in other regions of the central nervous system.

Scalable, Multithreaded, Partially-in-Place Sorting  

SciTech Connect

A recent trend in hardware development is producing computing systems that are stretching the number of cores and size of shared-memory beyond where most fundamental serial algorithms perform well. The expectation is that this trend will continue. So it makes sense to rethink our fundamental algorithms such as sorting. There are many situations where data that needs to be sorted will actually fit into the shared memory so applications could benefit from an efficient parallel sorting algorithm. When sorting large data (at least hundreds of Gigabytes) in a single shared memory, there are two factors that affect the algorithm choice. First, does the algorithm sort in-place? And second, does the algorithm scale well beyond tens of threads? Surprisingly, existing algorithms posses either one of these factors, but not both. We present an approach that gracefully degrades in performance as the amount of available working memory decreases relative to the size of the input.

Rapid matching in Drosophila place learning  

NASA Astrophysics Data System (ADS)

The level of conditioned behavior in animals is proportional to the intensity, amount, frequency, or probability of reinforcement. Interestingly, this matching can be dynamic, with performance levels following, for example, a switch in the probability of reinforcement with a short delay. We previously found that conditioned performance levels in Drosophila match reinforcement intensity in a place conditioning paradigm. Whether Drosophila can match conditioned behavior to a change in reinforcement intensity was an open question. In this study, we found that both conditioned behavior and memory levels match reinforcement intensity after a switch, and this rapid matching occurs within 2 min. Thus, fruit flies can dynamically match conditioned behavior and memory levels to a change in reinforcement intensity.

The place of dignity in everyday ethics.  

PubMed

Although ethics is often thought of in terms of "life-and-death" matters, many everyday situations involve ethics. Human dignity, a more recent way of expressing the belief that humans are made in the image of God (Genesis 1:26), captures the controversial notion that all humans are uniquely valuable and ought to be esteemed highly. Nurses have great opportunity to promote or demote dignity. A Christian holistic approach to ethics, exemplified by the narrative of the Good Samaritan (Luke 10:25-37), acknowledges the difficulty of always being ethical and integrates feeling, thinking, acting, and spirituality.

The place for performance in the digital holographic space  

NASA Astrophysics Data System (ADS)

In this series of digital art holograms and lenticulars, we are examining different kinds of movement inside the digital holographic space explored by Elizabeth Sandford-Richardson, a visual performance artist. During the process of capturing the image, we used the HoloCam Portable Light System, equipped with Canon and Nikon cameras positioned at different heights and angles, in order to improve the rendering of the holographic space. Based on the "Performativity of Performance Documentation" a notion introduced by Philip Auslanderi we revisit some authors that have been working in the "theatrical" practise, mainly in photography, adding the possibility of movement in 3D space. We must realise that the movement of the viewer in front of a digital holographic image creates the performance that he/she is looking at. We should consider the physical space, outside the hologram, and this kind of "performance acts", also part of the work. In summary, we propose a reflection on the digital holographic space, time, movement and its place in contemporary art.

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”.

Automating Shallow Seismic Imaging  

SciTech Connect

This seven-year, shallow-seismic reflection research project had the aim of improving geophysical imaging of possible contaminant flow paths. Thousands of chemically contaminated sites exist in the United States, including at least 3,700 at Department of Energy (DOE) facilities. Imaging technologies such as shallow seismic reflection (SSR) and ground-penetrating radar (GPR) sometimes are capable of identifying geologic conditions that might indicate preferential contaminant-flow paths. Historically, SSR has been used very little at depths shallower than 30 m, and even more rarely at depths of 10 m or less. Conversely, GPR is rarely useful at depths greater than 10 m, especially in areas where clay or other electrically conductive materials are present near the surface. Efforts to image the cone of depression around a pumping well using seismic methods were only partially successful (for complete references of all research results, see the full Final Technical Report, DOE/ER/14826-F), but peripheral results included development of SSR methods for depths shallower than one meter, a depth range that had not been achieved before. Imaging at such shallow depths, however, requires geophone intervals of the order of 10 cm or less, which makes such surveys very expensive in terms of human time and effort. We also showed that SSR and GPR could be used in a complementary fashion to image the same volume of earth at very shallow depths. The primary research focus of the second three-year period of funding was to develop and demonstrate an automated method of conducting two-dimensional (2D) shallow-seismic surveys with the goal of saving time, effort, and money. Tests involving the second generation of the hydraulic geophone-planting device dubbed the ''Autojuggie'' showed that large numbers of geophones can be placed quickly and automatically and can acquire high-quality data, although not under rough topographic conditions. In some easy-access environments, this device could make SSR surveying considerably more efficient and less expensive, particularly when geophone intervals of 25 cm or less are required. The most recent research analyzed the difference in seismic response of the geophones with variable geophone spike length and geophones attached to various steel media. Experiments investigated the azimuthal dependence of the quality of data relative to the orientation of the rigidly attached geophones. Other experiments designed to test the hypothesis that the data are being amplified in much the same way that an organ pipe amplifies sound have so far proved inconclusive. Taken together, the positive results show that SSR imaging within a few meters of the earth's surface is possible if the geology is suitable, that SSR imaging can complement GPR imaging, and that SSR imaging could be made significantly more cost effective, at least in areas where the topography and the geology are favorable. Increased knowledge of the Earth's shallow subsurface through non-intrusive techniques is of potential benefit to management of DOE facilities. Among the most significant problems facing hydrologists today is the delineation of preferential permeability paths in sufficient detail to make a quantitative analysis possible. Aquifer systems dominated by fracture flow have a reputation of being particularly difficult to characterize and model. At chemically contaminated sites, including U.S. Department of Energy (DOE) facilities and others at Department of Defense (DOD) installations worldwide, establishing the spatial extent of the contamination, along with the fate of the contaminants and their transport-flow directions, is essential to the development of effective cleanup strategies. Detailed characterization of the shallow subsurface is important not only in environmental, groundwater, and geotechnical engineering applications, but also in neotectonics, mining geology, and the analysis of petroleum reservoir analogs. Near-surface seismology is in the vanguard of non-intrusive approaches to increase knowledge of the shallow subsurface; our

Four decades, four places and four concepts.

Peptide chemistry has experienced enormous progress over the last decades, and the synthesis-oriented peptide scientist is confronted today with research domains at the interface of chemistry, biology and medicine. In this review, we look at some of our contributions over four decades, developed at four places in Germany and Switzerland. Special attention is given to four concepts which can be considered as nucleation seeds for some of today's research topics in peptide chemistry: (1) The use of polyethylene glycols (PEG) as solubilizing carriers in liquid-phase peptide synthesis which has resulted in the well known 'PEGylation' of peptides and proteins, (2) the construction of artificial proteins using topological templates, termed template-assembled synthetic proteins (TASP) which has stimulated the use of templates in peptide and protein design and mimicry, (3) pseudo-prolines which serve today as routine technology for the prevention of peptide self-association and beta-sheet formation in peptide synthesis, thus making accessible solid-phase synthesis of peptides up to the size of small proteins, and finally (4) studies on the onset of secondary structure and conformational transitions in designed oligo-peptides which resulted in the creation of 'switch-peptides' as folding precursors, allowing delineation of the molecular mechanism of protein folding and misfolding as an early step in peptide self-assembly and fibril formation relevant in degenerative diseases.

Image fusion with guided filtering.  

PubMed

A fast and effective image fusion method is proposed for creating a highly informative fused image through merging multiple images. The proposed method is based on a two-scale decomposition of an image into a base layer containing large scale variations in intensity, and a detail layer capturing small scale details. A novel guided filtering-based weighted average technique is proposed to make full use of spatial consistency for fusion of the base and detail layers. Experimental results demonstrate that the proposed method can obtain state-of-the-art performance for fusion of multispectral, multifocus, multimodal, and multiexposure images. PMID:23372084

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.

Phytonutrient deficiency: the place of palm fruit.  

PubMed

The oil palm (Elaeis guineensis) is native to many West African countries, where local populations have used its oil for culinary and other purposes. Large-scale plantations, established principally in tropical regions (Asia, Africa and Latin America), are mostly aimed at the production of oil, which is extracted from the fleshy mesocarp of the palm fruit, and endosperm or kernel oil. Palm oil is different from other plant and animal oils in that it contains 50% saturated fatty acids, 40% unsaturated fatty acids, and 10% polyunsaturated fatty acids. The fruit also contains components that can endow the oil with nutritional and health beneficial properties. These phytonutrients include carotenoids (alpha-,beta-,and gamma-carotenes), vitamin E (tocopherols and tocotrienols), sterols (sitosterol, stigmasterol and campesterol), phospholipids, glycolipids and squalene. In addition, it is recently reported that certain water-soluble powerful antioxidants, phenolic acids and flavonoids, can be recovered from palm oil mill effluent. Owing to its high content of phytonutrients with antioxidant properties, the possibility exists that palm fruit offers some health advantages by reducing lipid oxidation, oxidative stress and free radical damage. Accordingly, use of palm fruit or its phytonutrient-rich fractions, particularly water-soluble antioxidants, may confer some protection against a number of disorders or diseases including cardiovascular disease, cancers, cataracts and macular degeneration, cognitive impairment and Alzheimer's disease. However, whilst prevention of disease through use of these phytonutrients as in either food ingredients or nutraceuticals may be a worthwhile objective, dose response data are required to evaluate their pharmacologic and toxicologic effects. In addition, one area of concern about use of antioxidant phytonutrients is how much suppression of oxidation may be compatible with good health, as toxic free radicals are required for defence mechanisms. These food-health concepts would probably spur the large-scale oil palm (and monoculture) plantations, which are already seen to be a major cause of deforestation and replacement of diverse ecosystems in many countries. However, the environmental advantages of palm phytonutrients are that they are prepared from the readily available raw material from palm oil milling processes. Palm fruit, one of only a few fatty fruits, is likely to have an increasingly substantiated place in human health, not only through the provision of acceptable dietary fats, but also its characteristic protective phytonutrients.

Autogeneration of fractal photographic mosaic images  

Microsoft Academic Search

We present a novel method for the creation of photographic mosaic images using fractals generated via evo- lutionary techniques. A photomosaic is a rendering of an image performed by placing a grid of smaller images that permit the original image to be visible when viewed from a distance. The problem of selecting the smaller images is a computationally intensive one.

Hebbian Analysis of the Transformation of Medial Entorhinal Grid-Cell Inputs to Hippocampal Place Fields  

PubMed Central

The discovery of grid cells in the medial entorhinal cortex (MEC) permits the characterization of hippocampal computation in much greater detail than previously possible. The present study addresses how an integrate-and-fire unit driven by grid-cell spike trains may transform the multipeaked, spatial firing pattern of grid cells into the single-peaked activity that is typical of hippocampal place cells. Previous studies have shown that in the absence of network interactions, this transformation can succeed only if the place cell receives inputs from grids with overlapping vertices at the location of the place cell's firing field. In our simulations, the selection of these inputs was accomplished by fast Hebbian plasticity alone. The resulting nonlinear process was acutely sensitive to small input variations. Simulations differing only in the exact spike timing of grid cells produced different field locations for the same place cells. Place fields became concentrated in areas that correlated with the initial trajectory of the animal; the introduction of feedback inhibitory cells reduced this bias. These results suggest distinct roles for plasticity of the perforant path synapses and for competition via feedback inhibition in the formation of place fields in a novel environment. Furthermore, they imply that variability in MEC spiking patterns or in the rat's trajectory is sufficient for generating a distinct population code in a novel environment and suggest that recalling this code in a familiar environment involves additional inputs and/or a different mode of operation of the network.

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

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).

PROPELLER MRI visualizezs detailed pathology of hippocampal sclerosis  

PubMed Central

Purpose: Hippocampal sclerosis (HS) is the most common cause of refractory temporal lobe epilepsy. Histopathologically, HS is characterized by neuron loss and gliosis. HS can be identified on MRI by signal increase on T2-weighted images and volume loss on T1-weighted volume images. The Periodically Rotated Overlapping Parallel Lines with Enhanced Reconstruction (“PROPELLER”) sequence has excellent contrast between grey and white matter and compensates for subjects moving during the scan. The aim of the current report was to explore PROPELLER image quality of the hippocampus compared to routine sequences. Methods: Routine sequences (T1 volume, T2-weighted, PD and FLAIR images) and PROPELLER images were acquired in four presurgical patients with HS using a GE 3T Excite HD scanner (General Electric). Resected tissue was stained with LFB, and for GFAP, NeuN and dynorphin immunohistochemistry. Hippocampal sections were compared with PROPELLER images. Results: PROPELLER images were T2-weighted and had superior tissue contrast compared to routine sequences. PROPELLER images showed the internal hippocampal structures and tissue changes associated with HS. This corresponded to changes seen on histopathological sections confirming that the sequence could distinguish between different strata and subfields of the hippocampus. Discussion: The PROPELLER sequence shows promise for detailed in vivo imaging of the hippocampus in patients who did not move overtly, negating the inevitable subtle movements during scans. More detailed in vivo studies of the hippocampal formation, investigating subtle abnormalities such as end folium sclerosis, and the neocortex are now possible and may increase the diagnostic yield of MRI.

Whose place is it anyway? Representational politics in a place-based health initiative.  

PubMed

The association between place and poor health, such as chronic disease, is well documented and in recent years has given rise to public health strategies such as place-based initiatives (PBIs). This article reports on the emergence of one such initiative in Australia, in regions identified as culturally diverse and socially disadvantaged. The study draws on the intellectual resources provided by governmentality and actor-network theory to provide insights into the reasons why community actors were excluded from a new governance body established to represent their interests. Risk-thinking and representational politics determined who represented whom in the PBI partnership. Paradoxically, actors representing 'community', identified as being 'at risk', were excluded from the partnership during its translation because they were also identified as being 'a risk'. As a consequence, contrary to federal government health and social policy in Australia, it was state government interests rather than the interests of community actors that influenced decisions made in relation to local health planning and the allocation of resources.

Place matters: The impact of place of residency on racial attitudes among regional and urban migrants.  

PubMed

Scholars have debated whether racial attitudes are socialized early in life and persist throughout one's lifetime or are open to influences from one's environment as an adult. This study introduces another approach that holds that place, as opposed to the timing of socialization, is an important consideration for the socialization of racial attitudes. Using data from the American National Election Study, we consider the effect of region and urban residency on racial attitudes by comparing lifelong residents of these locations to those who migrate into and out of them. Using improved measures of early life socialization and region of residency, we conclude that a place-based model can be used to explain the socialization of racial resentment. For regional migrants, those moving into and out of the non-South maintain levels of racial resentment similar to non-Southern stayers. For urban migrants, the lifelong openness model of socialization was most appropriate. These migrants were more likely to change and adopt the level of racial resentment similar to that of their destination peers. These findings generally persist across time. PMID:24913952

Route visualization using detail lenses.  

PubMed

We present a method designed to address some limitations of typical route map displays of driving directions. The main goal of our system is to generate a printable version of a route map that shows the overview and detail views of the route within a single, consistent visual frame. Our proposed visualization provides a more intuitive spatial context than a simple list of turns. We present a novel multifocus technique to achieve this goal, where the foci are defined by points of interest (POI) along the route. A detail lens that encapsulates the POI at a finer geospatial scale is created for each focus. The lenses are laid out on the map to avoid occlusion with the route and each other, and to optimally utilize the free space around the route. We define a set of layout metrics to evaluate the quality of a lens layout for a given route map visualization. We compare standard lens layout methods to our proposed method and demonstrate the effectiveness of our method in generating aesthetically pleasing layouts. Finally, we perform a user study to evaluate the effectiveness of our layout choices. PMID:20075484

The Special Place Project: Efficacy of a Place-Based Case Study Approach for Teaching Geoscience  

NASA Astrophysics Data System (ADS)

Achieving geoscience literacy of the general population has become increasingly important world wide as ever more connected and growing societies depend more and more on our planet's limited natural resource base. Building citizen understanding of their dependence on the local environment, and the geologic processes which created and continue to change it, has become a great challenge to educators at all levels of the education system. The Special Place Project described in this presentation explores use of a place-based case study approach combining instruction in geoscience content with development of observation, reasoning, writing and presentation skills. The approach allows students to select the locations for their individual case studies affording development of personal connections between the learner and his environment. The approach gives instructors at many grade levels the ability to develop core pedagogical content and skills while exploring the unique geologic environments relevant to the local population including such critical issues as land use, resource depletion, energy, climate change and the future of communities in a changing world. The geologic reasons for the location of communities and key events in their histories can be incorporated into the students' case studies as appropriate. The project is unique in placing all course instruction in the context of the quest to explore and gain understanding of the student's chosen location by using the inherently more generalized course content required by the curriculum. By modeling how scientists approach their research questions, this pedagogical technique not only integrates knowledge and skills from across the curriculum, it captures the excitement of scientific thinking on real world questions directly relevant to students' lives, increasing student engagement and depth of learning as demonstrated in the case study reports crafted by the students and exam results. Student learning of topics directly touched upon by the case study, such as geomorphologic features and processes observable at Earth's surface, is compared to learning on more abstract topics, such as subsurface Earth structure and tectonic processes, to provide a quantitative assessment of this pedagogical approach.

Detailed fuel spray analysis techniques  

NASA Technical Reports Server (NTRS)

Detailed fuel spray analyses are a necessary input to the analytical modeling of the complex mixing and combustion processes which occur in advanced combustor systems. It is anticipated that by controlling fuel-air reaction conditions, combustor temperatures can be better controlled, leading to improved combustion system durability. Thus, a research program is underway to demonstrate the capability to measure liquid droplet size, velocity, and number density throughout a fuel spray and to utilize this measurement technique in laboratory benchmark experiments. The research activities from two contracts and one grant are described with results to data. The experiment to characterize fuel sprays is also described. These experiments and data should be useful for application to and validation of turbulent flow modeling to improve the design systems of future advanced technology engines.

[Image processing and radiotherapy].  

PubMed

Medical images are of great importance in radiotherapy, which became a privileged application field for image processing techniques. Moreover, because of the progression of the computers' performances, these techniques are also in full expansion. Today, the recent developments of the radiotherapy (3DCR, IMRT) offer a huge place to them. Effectively, they can potentially answer to the precision requirements of the modern radiotherapy, and may then contribute to improve the delivered treatments. The purpose of this article is to present the different image processing techniques that are currently used in radiotherapy (including image matching and segmentation) as they are described in the literature.

Image processing and recognition for biological images  

PubMed Central

This paper reviews image processing and pattern recognition techniques, which will be useful to analyze bioimages. Although this paper does not provide their technical details, it will be possible to grasp their main tasks and typical tools to handle the tasks. Image processing is a large research area to improve the visibility of an input image and acquire some valuable information from it. As the main tasks of image processing, this paper introduces gray-level transformation, binarization, image filtering, image segmentation, visual object tracking, optical flow and image registration. Image pattern recognition is the technique to classify an input image into one of the predefined classes and also has a large research area. This paper overviews its two main modules, that is, feature extraction module and classification module. Throughout the paper, it will be emphasized that bioimage is a very difficult target for even state-of-the-art image processing and pattern recognition techniques due to noises, deformations, etc. This paper is expected to be one tutorial guide to bridge biology and image processing researchers for their further collaboration to tackle such a difficult target.

Photoacoustic imaging in biomedicine  

NASA Astrophysics Data System (ADS)

Photoacoustic imaging (also called optoacoustic or thermoacoustic imaging) has the potential to image animal or human organs, such as the breast and the brain, with simultaneous high contrast and high spatial resolution. This article provides an overview of the rapidly expanding field of photoacoustic imaging for biomedical applications. Imaging techniques, including depth profiling in layered media, scanning tomography with focused ultrasonic transducers, image forming with an acoustic lens, and computed tomography with unfocused transducers, are introduced. Special emphasis is placed on computed tomography, including reconstruction algorithms, spatial resolution, and related recent experiments. Promising biomedical applications are discussed throughout the text, including (1) tomographic imaging of the skin and other superficial organs by laser-induced photoacoustic microscopy, which offers the critical advantages, over current high-resolution optical imaging modalities, of deeper imaging depth and higher absorption contrasts, (2) breast cancer detection by near-infrared light or radio-frequency-wave-induced photoacoustic imaging, which has important potential for early detection, and (3) small animal imaging by laser-induced photoacoustic imaging, which measures unique optical absorption contrasts related to important biochemical information and provides better resolution in deep tissues than optical imaging.

Deweyan integration: moving beyond place attachment in elderly migration theory.  

PubMed

The fact that aging-in-place and elderly migration are intricately linked has been overlooked by behavioral approaches to elderly migration. "Humanistic" inquiry has provided important insights into aging-in-place and elderly migration as well as the connection between the two. Humanistic approaches, however, do not encapsulate the full range of experience involved in elders' lives. To move beyond humanistic research and key concepts such as place attachment, the philosophy of John Dewey is introduced. Dewey's viewpoint is merged with the geographical concept of place into what is termed "place integration." This perspective is subsequently compared with humanistic perspectives on aging-in-place and elderly migration decision-making. Fundamental differences such as temporal orientation and substantive focus are illustrated and discussed. Conclusions address the utility of such a perspective. PMID:11310573

Beyond conventional migration: non-linear elastic subsalt imaging with transmissions and two-sided illumination  

NASA Astrophysics Data System (ADS)

Source-receiver interferometric imaging can be used to synthesize a subsurface acoustic or elastic image, consisting of a zero-time, zero-offset response (or Green's function) between a colocated pseudo-source and pseudo-receiver placed at each point in the subsurface image. However, if the imaging process does not properly account for multiple reflections, and enclosing boundaries of sources and receivers are not available, the image shows artefacts, poorly illuminated areas and distorted image amplitudes. Here we demonstrate with numerical examples that two-sided non-linear imaging provides the best elastic pure-mode (PP and SS) and converted-mode (PS) images, having higher resolution and more uniform illumination than those obtained from both one-sided linear imaging and from other intermediate steps of imaging (e.g. non-linear one-sided, linear two-sided). We also propose practical approaches to construct the additional fields required by two-sided non-linear imaging without the need for a detailed velocity model and receivers (and/or sources) in the subsurface. Moreover, when conversions are used for imaging, `true-amplitude' images (here true-amplitude means properly retrieving amplitudes that represent the zero-time, zero-offset elastic response) should theoretically vanish because neither P-to-S or S-to-P conversions arise at zero-time and zero-offset. Applying a correction procedure that accounts for the polarity reversal in PS (or SP) single-shot images helps with their structural interpretation but results in an unphysical estimate of the subsurface response and uninterpretable amplitudes. This suggests that there are advantages in exploiting pure-mode SS reflections/transmissions, in addition to converted waves only, because they require no polarity correction and the resulting image contains meaningful amplitudes that are proportional to the local shear-wave properties of the medium.

Cycloheximide enhances maintenance of methamphetamine-induced conditioned place preference.  

PubMed

Accrued evidence demonstrated the necessity of protein synthesis at acquisition, consolidation and expression stages in conditioning/learning tasks, while the underlying mechanisms of the maintenance of memory remained less explored. This study was designed to characterize the maintenance of methamphetamine-induced conditioned place preference, a drug-induced learning and memory. In addition, cycloheximide, a protein synthesis inhibitor, was used to examine the involvement of protein synthesis in the maintenance of such place preference memory. We found that the maintenance of the rapidly-established methamphetamine (2 mg/kg, i.p.) -induced conditioned place preference could be long-lasting and even over fifty days under the present protocol of extinction. Moreover, it was of interest to note the undulating expression of this conditioned place preference throughout the extinction protocol. Most importantly, as the methamphetamine-induced conditioned place preference was acquired and expressed by mice, the saline-pretreated control mice underwent numbers of intermittent extinction across a long-term retention test period, while cycloheximide-pretreated mice exhibited unaltered methamphetamine-induced conditioned place preference throughout the same retention test period. Taken together, we conclude that [1] methamphetamine-induced conditioned place preference could last for a long period of time, and such place preference memory is reluctant to extinguish even animals' repeated exposure to the previous conditioned environment at a drug-free status, and [2] blockade of protein synthesis may enhance the maintenance of the methamphetamine-induced conditioned place preference.

The Finer Details: Climate Modeling  

NASA Technical Reports Server (NTRS)

If you want to know whether you will need sunscreen or an umbrella for tomorrow's picnic, you can simply read the local weather report. However, if you are calculating the impact of gas combustion on global temperatures, or anticipating next year's rainfall levels to set water conservation policy, you must conduct a more comprehensive investigation. Such complex matters require long-range modeling techniques that predict broad trends in climate development rather than day-to-day details. Climate models are built from equations that calculate the progression of weather-related conditions over time. Based on the laws of physics, climate model equations have been developed to predict a number of environmental factors, for example: 1. Amount of solar radiation that hits the Earth. 2. Varying proportions of gases that make up the air. 3. Temperature at the Earth's surface. 4. Circulation of ocean and wind currents. 5. Development of cloud cover. Numerical modeling of the climate can improve our understanding of both the past and, the future. A model can confirm the accuracy of environmental measurements taken. in, the past and can even fill in gaps in those records. In addition, by quantifying the relationship between different aspects of climate, scientists can estimate how a future change in one aspect may alter the rest of the world. For example, could an increase in the temperature of the Pacific Ocean somehow set off a drought on the other side of the world? A computer simulation could lead to an answer for this and other questions. Quantifying the chaotic, nonlinear activities that shape our climate is no easy matter. You cannot run these simulations on your desktop computer and expect results by the time you have finished checking your morning e-mail. Efficient and accurate climate modeling requires powerful computers that can process billions of mathematical calculations in a single second. The NCCS exists to provide this degree of vast computing capability.

Space Radar Image of Safsaf Oasis, Egypt  

NASA Technical Reports Server (NTRS)

This three-frequency space radar image of south-central Egypt demonstrates the unique capability of imaging radar to penetrate thin sand cover in arid regions to reveal hidden details below the surface. Nearly all of the structures seen in this image are invisible to the naked eye and to conventional optical satellite sensors. Features appear in various colors because the three separate radar wavelengths are able to penetrate the sand to different depths. Areas that appear red or orange are places that can be seen only by the longest wavelength, L-band, and they are the deepest of the buried structures. Field studies in this area indicate L-band can penetrate as much as 2 meters (6.5 feet) of very dry sand to image buried rock structures. Ancient drainage channels at the bottom of the image are filled with sand more than 2 meters (6.5 feet) thick and therefore appear dark because the radar waves cannot penetrate them. The fractured orange areas at the top of the image and the blue circular structures in the center of the image are granitic areas that may contain mineral ore deposits. Scientists are using the penetrating capabilities of radar imaging in desert areas in studies of structural geology, mineral exploration, ancient climates, water resources and archaeology. This image is 51.9 kilometers by 30.2 kilometers (32.2 miles by 18.7 miles) and is centered at 22.7 degrees north latitude, 29.3degrees east longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations as follows: red is L-band, horizontally transmitted and received; green is C-band, horizontally transmitted and received; and blue is X-band, vertically transmitted and received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) on April 16, 1994, on board the space shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission to Planet Earth program.

Distribution of aerosols in mouse lobes by fluorescent imaging.  

PubMed

Better methods are needed to quantify the distribution of drug among the airways of the lungs of small animals to facilitate the development of agents that can target specific airways. Mice were exposed to aerosols of aluminum phthalocyanine tetrasulfonic acid (AlPCS) that ranged in concentration and size (0.2-2.8 ?m). The trachea and lobes were removed and placed between glass slides, and fluorescent images were obtained at two different compression thicknesses. The intensity, normalized by the area, exposure time, and thickness, was then plotted as a function of compression thickness, from which the concentration and attenuation coefficient were estimated for each lobe and then for each pixel of the image. The latter was then used to generate an image reflective of the concentration. The lobe volume, concentration, and tissue attenuation of AlPCS was consistent among the lobes. The deposition fraction increased with decreasing particle size. The network of lines in the concentration image indicated that connective tissue has a lower concentration. The central airways were clearly evident in the images of mice exposed to the very small and large aerosols. This approach provides a rapid, economical means to obtain high resolution images of mouse lungs from which detailed analysis of the distribution of deposited aerosol particles can be obtained.

Teaching Geoscience in Place for Local Diversity and Sustainability  

NASA Astrophysics Data System (ADS)

Globalization, careerism, media, thoughtless consumption, standardized education and assessment, and even well-meaning advocacy for far-flung environments and people all divert our attention from meaningful interaction with our own surroundings. Meanwhile, many young Americans prefer virtual realities over personal intimacy with nature. Many have lost sight of the pedagogical power of places: localities imbued with meaning by human experience. To lack a sense of local places is to be oblivious to their environmental, cultural, and aesthetic importance, and to risk acceding to their degradation. The geosciences, born and rooted in exploration of environments, have much to lose from this trend but can be pivotal in helping to reverse it. Place-based teaching is situated in local physical and cultural environments and blends experiential learning, transdisciplinary and multicultural content, and service to the community. It is advocated for its relevance and potential to engage diverse students. Authentically place-based education is informed not only by scientific knowledge of places but also by the humanistic meanings and attachments affixed to them. Leveraging and enriching the senses of place of students, teachers, and the community is a defining and desirable learning outcome. We have researched and piloted several place-based approaches to geoscience teaching at various places in the Southwest USA: at a rural Tribal College, a large urban university, and a teacher in-service program at an underserved, minority-majority rural school district. Curricula are situated in complexly evolved, ruggedly beautiful desert-mountain physical landscapes coincident with multicultural, deeply historic, but rapidly changing cultural landscapes. The organizing theme is a cyclical path of inquiry through Earth and Sky, derived from Indigenous ethnogeology; syllabi integrate geology, hydrology, climate, environmental quality, and cultural geography and are situated in real places within the Greater Southwest. Field studies are included as often as possible. Students review and discuss the geoscientific context and social implications of selected regional issues such as mining and water management. Courses are open to all and promoted to in-service and pre-service K-12 teachers. Front-end, formative, and summative evaluations use mixed methods based in theories of place attachment and experiential learning. Psychometric surveys of the diverse participants reveal variable prior senses of place and limited correlation with expected predictors such as ethnicity, but pre- and post-surveys show significant relative increases in sense of place. From these data and our qualitative findings (coded from participant observations, analysis of student products, and semi-structured exit interviews) we infer that students' knowledge of and attachments to Southwest places were enhanced by the place-based approach to teaching.

Intracellular dynamics of hippocampal place cells during virtual navigation  

PubMed Central

Hippocampal place cells encode spatial information in rate and temporal codes. To examine the mechanisms underlying hippocampal coding, we measured the intracellular dynamics of place cells by combining in vivo whole cell recordings with a virtual reality system. Head-restrained mice, running on a spherical treadmill, interacted with a computer-generated visual environment to perform spatial behaviors. Robust place cell activity was present during movement along a virtual linear track. From whole cell recordings, we identified three subthreshold signatures of place fields: (1) an asymmetric ramp-like depolarization of the baseline membrane potential; (2) an increase in the amplitude of intracellular theta oscillations; and, (3) a phase precession of the intracellular theta oscillation relative to the extracellularly-recorded theta rhythm. These intracellular dynamics underlie the primary features of place cell rate and temporal codes. The virtual reality system developed here will enable new experimental approaches to study the neural circuits underlying navigation.

The selection of shelter place by the house cricket.  

PubMed

The stimuli acting upon the choice of shelter and resting place by the house cricket, Acheta domesticus (L.) were analysed. The places of preference in different types of terraria as well as the choice of tubes of different diameter and of various light conditions were investigated. Acheta domesticus avoids open and illuminated space in its choice of resting place. It prefers dark places, enclosed by walls, like a clefts or boxes. The influence of the conditions of environment configuration at the larval period of the crickets' development upon their subsequent preference as to rest place, has not been stated. Neither was this influence observed on their behavioural reactions as connected with the former. Crickets attain their ethological praeferendum of resting site owing to their innate photo- and thigmo-kinesis which are supplemented by hygrophilia and thermophilia. The influence of the group effect on the cricket's individual rate of development was confirmed. PMID:1007977

This places an increasing demand on radiology services, particularly as the complication rates are not insignificant. The imaging appearances of pancreas transplants and their complications can be difficult to interpret. This review provides an illustrative journey through the anatomical appearances of a graft and the imaging appearances of complications, as a reference tool for radiologists. PMID:24026227

Unlike computed tomographic images and mag- netic resonance images (MRIs), sectioned images of the human body with real color and high resolution have certain advan- tages in learning and teaching anatomy. Comparisons between sectioned images of the brain and MRIs are useful in many ways. Therefore, we prepared 312 MRIs at ultrahigh field 7.0 T (axial direction 0:4 ? 0:4

a New Tool for Facilitating the Retrieval and Recording of the Place Name Cultural Heritage  

NASA Astrophysics Data System (ADS)

Traditional place names (toponyms) represent the immaterial cultural heritage of past land uses, particular characteristics of the territory, landscape related events or inhabitants, as well as related cultural and religious background. In Euopean countries where the cultural landscape has a very long history, this heritage is particularly considerable. Often most of the detailed knowledge about traditional place names and their precise localization is non-written and familiar only to old local native persons who experienced the former rural civilization. In the next future this important heritage will be seriously threatened because of the physical disappearance of its living custodians. One of the major problems that one has to face, when trying to trace and document the knowledge related to place names and their localization, is to translate the memory and the former landscape experiences of the respondents into maps and structured records. In this contribution we present a new tool based on the monoplotting principle and ad hoc developed to enable the synchronization of terrestrial oblique landscape pictures with the represented digital elevation model. The local respondents are then just asked to show the place name localization on historical landscape pictures they are familiar with. The tool automatically gives back the corresponding world coordinates, what makes the interviewing process more rapid and smooth as well as motivating and less stress-inducing for the informants.

Putting Geography Education into Place: What Geography Educators Can Learn from Place-Based Education, and Vice Versa  

ERIC Educational Resources Information Center

In recent years, geography educators have sought to make their pedagogy relevant to pressing social and environmental issues, but these efforts have largely imported pedagogies from outside of geography. In place-based education, in contrast, place--one of geography's defining themes--serves as a central organizing principle for a socially…

[Wavelet threshold denoising algorithm for CR images].  

PubMed

A wavelet threshold denoising algorithm for CR images is put forward here . A noised CR image is decomposed into wavelet coefficients, which are processed by the algorithm, and the denoised CR image is reconstructed based on the processed coefficients. Examples are too presented to demonstrate the efficiency of the algorithm on denoising and, maintaining the detail of the CR images. PMID:16646417

An environmental sampling model for combining judgment and randomly placed samples  

SciTech Connect

In the event of the release of a lethal agent (such as anthrax) inside a building, law enforcement and public health responders take samples to identify and characterize the contamination. Sample locations may be rapidly chosen based on available incident details and professional judgment. To achieve greater confidence of whether or not a room or zone was contaminated, or to certify that detectable contamination is not present after decontamination, we consider a Bayesian model for combining the information gained from both judgment and randomly placed samples. We investigate the sensitivity of the model to the parameter inputs and make recommendations for its practical use.

Tracking the general circulation of Jupiter's atmosphere with images obtained by small telescopes  

NASA Astrophysics Data System (ADS)

One of the most characteristic feature of Jupiter's atmosphere is its global wind structure which is characterized by strong zonal winds alternating in latitude and correlated with the bright Zones and dark Belts of the planet. This wind system presents a marked temporal stability although the structure of some of its bands change strongly in a quasi-periodic way. The wind system keeps also stable when dynamic perturbations occur such as the development of great convective storms or when impacts like those of 1994 and 2009 take place. Nowadays, amateur astronomers of all the planet obtain great Jupiter images at their telescopes' resolution limit using the "lucky imaging'' technique and they share their data in data-bases that centralize them. In this work we analyzed the higher quality images from the data base of the International Outer Planet Watch (IOPW) to study the possible temporal variations of the planet's wind profile. To do so, we used image pairs separated by one or two planetary rotations in which we can measure the winds by tracking cloud details present in both images. To measure the displacement of the details we used both a correlation technique and the manual cloud tracking. Even if these kind of studies have been previously performed using high quality images from spacial mission or Hubble Space Telescope the possibility of analysing the general circulation of the planet with small telescope observations opens a new possibility for a continuum study of the atmospheric dynamic of Jupiter.

Image guidance in pituitary surgery.  

PubMed

Image guidance in pituitary surgery has evolved since diagnostic imaging of the sellar region was first introduced at the turn of the 20th century. These advances have played a key role in the decrease in morbidity and mortality once associated with pituitary surgery. This chapter details the history of sellar imaging as a preoperative diagnostic aide, and then examines the subsequent development of image guidance systems and intraoperative imaging. The utility and limitations of common intraoperative aides including video fluoroscopy, frameless stereotaxy, ultrasound, and magnetic resonance imaging are reviewed. PMID:16474215

Corrosive places, inhuman spaces: mental health in Australian immigration detention.  

PubMed

Since their establishment in 1992, Australian Immigration Detention Centres have been the focus of increasing concern due to allegations of their serious impact on the mental health of asylum seekers. Informed by Foucault's treatise on surveillance and the phenomenological work of Casey, this paper extends the current clinical data by examining the architecture and location of detention centres, and the complex relationships between space, place and mental health. In spatialising these relationships, we argue that Immigration Detention Centres operate not only as Panopticons, but are embodied by asylum seekers as 'anti-places': as places that mediate and constitute thinned out and liminal experiences. In particular, it is the embodied effects of surveillance and suspended liminality that impact on mental health. An approach which locates the embodiment of place and space as central to the poor mental health of asylum seekers adds an important dimension to our understandings of (dis)placement and mental health in the lives of the exiled.

What do grid cells contribute to place cell firing?  

PubMed Central

The unitary firing fields of hippocampal place cells are commonly assumed to be generated by input from entorhinal grid cell modules with differing spatial scales. Here, we review recent research that brings this assumption into doubt. Instead, we propose that place cell spatial firing patterns are determined by environmental sensory inputs, including those representing the distance and direction to environmental boundaries, while grid cells provide a complementary self-motion related input that contributes to maintaining place cell firing. In this view, grid and place cell firing patterns are not successive stages of a processing hierarchy, but complementary and interacting representations that work in combination to support the reliable coding of large-scale space.

Retention of sealants placed by dental technicians without assistance.  

PubMed

The retention rate of sealants placed by dental auxiliaries has not been studied extensively. This study recorded and compiled the retention rate of sealants placed by Air Force dental technicians over a two-year period. The technicians, who were equivalent to dental assistants, were trained to place the sealants without assistance using the Vac-Ejector (Whaledent International, New York, NY) system for isolation. Five hundred and ninety-nine sealants on 90 patients were evaluated an average of 13.9 months after sealant placement. The overall complete retention rate was 91.0%, with a partial loss rate of 7.0%, and a complete loss rate of 2.0%. These results suggest that pit and fissure sealants can be placed in this cost-effective manner with a relatively high retention rate. PMID:1945987
