Planetary Image Geometry Library  

NASA Technical Reports Server (NTRS)

The Planetary Image Geometry (PIG) library is a multi-mission library used for projecting images (EDRs, or Experiment Data Records) and managing their geometry for in-situ missions. A collection of models describes cameras and their articulation, allowing application programs such as mosaickers, terrain generators, and pointing correction tools to be written in a multi-mission manner, without any knowledge of parameters specific to the supported missions. Camera model objects allow transformation of image coordinates to and from view vectors in XYZ space. Pointing models, specific to each mission, describe how to orient the camera models based on telemetry or other information. Surface models describe the surface in general terms. Coordinate system objects manage the various coordinate systems involved in most missions. File objects manage access to metadata (labels, including telemetry information) in the input EDRs and RDRs (Reduced Data Records). Label models manage metadata information in output files. Site objects keep track of different locations where the spacecraft might be at a given time. Radiometry models allow correction of radiometry for an image. Mission objects contain basic mission parameters. Pointing adjustment ("nav") files allow pointing to be corrected. The object-oriented structure (C++) makes it easy to subclass just the pieces of the library that are truly mission-specific. Typically, this involves just the pointing model and coordinate systems, and parts of the file model. Once the library was developed (initially for Mars Polar Lander, MPL), adding new missions ranged from two days to a few months, resulting in significant cost savings as compared to rewriting all the application programs for each mission. Currently supported missions include Mars Pathfinder (MPF), MPL, Mars Exploration Rover (MER), Phoenix, and Mars Science Lab (MSL). Applications based on this library create the majority of operational image RDRs for those missions. A Java wrapper around the library allows parts of it to be used from Java code (via a native JNI interface). Future conversions of all or part of the library to Java are contemplated.

Medical image libraries: ICoS project  

NASA Astrophysics Data System (ADS)

FOr use of digital techniques for the production, manipulation and storage of images has resulted in the creation of digital image libraries. These libraries often store many thousands of images. While provision of storage media for such large amounts of data has been straightforward, provision of effective searching and retrieval tools has not. Medicine relies heavily on images as a diagnostic tool. The most obvious example is the x-ray, but many other image forms are in everyday use. Advances in technology are affecting the ways medical images are generated, stored and retrieved. The paper describes the work of the Image COding and Segmentation to Support Variable Rate Transmission Channels and Variable Resolution Platforms (ICoS) research project currently under way in Bristol, UK. ICoS is a project of the Mobile of England and Hewlett-Packard Research Laboratories Europe. Funding is provided by the Engineering and PHysical Sciences Research Council. The aim of the ICoS project is to demonstrate the practical application of computer networking to medical image libraries. Work at the University of the West of England concentrates on user interface and indexing issues. Metadata is used to organize the images, coded using the WWW Consortium standard Resource Description Framework. We are investigating the application of such standards to medical images, one outcome being to implement a metadata-based image library. This paper describes the ICoS project in detail and discuses both metadata system and user interfaces in the context of medical applications.

NSDL National Science Digital Library

Google has an image search engine, which claims to be the most comprehensive on the Web, indexing over 150 million images. Keyword searches produce return pages with 20 thumbnails, each of which includes image size information and the URL of the source page. Clicking on a thumbnail produces a framed page with a larger image of the thumbnail above the full page on which the image was found. Users can turn off the frame using a button on the top right. All of the advanced search commands are available with image search, and users can also limit their search to a specific file format. There is an adult content filter option (default is on), but Google warns users that some adult content may potentially slip through.

National Portrait Gallery Picture Library Search  

NSDL National Science Digital Library

The (UK) National Portrait Gallery's online portrait database now has a search feature, ideal for all of us who eagerly flip to the back of a book's dust jacket for the author's picture or check a Website's "about" section for images of its creators. The online database contains approximately 10,000 images selected from the million or more portraits of famous Britons in the Gallery's collection. Using simple search, users enter a name and click a radio button indicating whether the person is a portrait artist or sitter. The search returns, however, include links to the work of sitters who are artists as well. For example, searching on John Singer Sargent yields one portrait of the artist and 45 by him. Clicking the radio button for portrait executes a search by title. In advanced search, it is possible to search by profession, such as explorer or food writer, or broader categories of professions, including travel and exploration, education, or literature and writing.

Semantically Enriching the Search System of a Music Digital Library  

NASA Astrophysics Data System (ADS)

Traditional search systems are usually based on keywords, a very simple and convenient mechanism to express a need for information. This is the most popular way of searching the Web, although it is not always an easy task to accurately summarize a natural language query in a few keywords. Working with keywords means losing the context, which is the only thing that can help us deal with ambiguity. This is the biggest problem of keyword-based systems. Semantic Web technologies seem a perfect solution to this problem, since they make it possible to represent the semantics of a given domain. In this chapter, we present three projects, Harmos, Semusici and Cantiga, whose aim is to provide access to a music digital library. We will describe two search systems, a traditional one and a semantic one, developed in the context of these projects and compare them in terms of usability and effectiveness.

Ontology driven image search engine  

NASA Astrophysics Data System (ADS)

Image collections are most often domain specific. We have developed a system for image retrieval of multimodal microscopy images. That is, the same object of study visualized with a range of microscope techniques and with a range of different resolutions. In microscopy, image content is depending on the preparation method of the object under study as well as the microscope technique. Both are taken into account in the submission phase as metadata whilst at the same time (domain specific) ontologies are employed as controlled vocabularies to annotate the image. From that point onward, image data are interrelated through the relationships derived from annotated concepts in the ontology. By using concepts and relationships of an ontology, complex queries can be built with true semantic content. Image metadata can be used as powerful criteria to query image data which are directly or indirectly related to original data. The results of image retrieval can be represented using a structural graph by exploiting relationships from ontology rather than a listed table. Applying this to retrieve images from the same subject at different levels of resolution opens a new field for the analysis of image content.

Interactive searching of facial image databases  

NASA Astrophysics Data System (ADS)

A set of psychological facial descriptors has been devised to enable computerized searching of criminal photograph albums. The descriptors have been used to encode image databased of up to twelve thousand images. Using a system called FACES, the databases are searched by translating a witness' verbal description into corresponding facial descriptors. Trials of FACES have shown that this coding scheme is more productive and efficient than searching traditional photograph albums. An alternative method of searching the encoded database using a genetic algorithm is currenly being tested. The genetic search method does not require the witness to verbalize a description of the target but merely to indicate a degree of similarity between the target and a limited selection of images from the database. The major drawback of FACES is that is requires a manual encoding of images. Research is being undertaken to automate the process, however, it will require an algorithm which can predict human descriptive values. Alternatives to human derived coding schemes exist using statistical classifications of images. Since databases encoded using statistical classifiers do not have an obvious direct mapping to human derived descriptors, a search method which does not require the entry of human descriptors is required. A genetic search algorithm is being tested for such a purpose.

Pepitome: evaluating improved spectral library search for identification complementarity and quality assessment  

PubMed Central

Spectral libraries have emerged as a viable alternative to protein sequence databases for peptide identification. These libraries contain previously detected peptide sequences and their corresponding tandem mass spectra (MS/MS). Search engines can then identify peptides by comparing experimental MS/MS scans to those in the library. Many of these algorithms employ the dot product score for measuring the quality of a spectrum-spectrum match (SSM). This scoring system does not offer a clear statistical interpretation and ignores fragment ion m/z discrepancies in the scoring. We developed a new spectral library search engine, Pepitome, which employs statistical systems for scoring SSMs. Pepitome outperformed the leading library search tool, SpectraST, when analyzing data sets acquired on three different mass spectrometry platforms. We characterized the reliability of spectral library searches by confirming shotgun proteomics identifications through RNA-Seq data. Applying spectral library and database searches on the same sample revealed their complementary nature. Pepitome identifications enabled the automation of quality analysis and quality control (QA/QC) for shotgun proteomics data acquisition pipelines. PMID:22217208

Histology image search using multimodal fusion.  

PubMed

This work proposes a histology image indexing strategy based on multimodal representations obtained from the combination of visual features and associated semantic annotations. Both data modalities are complementary information sources for an image retrieval system, since visual features lack explicit semantic information and semantic terms do not usually describe the visual appearance of images. The paper proposes a novel strategy to build a fused image representation using matrix factorization algorithms and data reconstruction principles to generate a set of multimodal features. The methodology can seamlessly recover the multimodal representation of images without semantic annotations, allowing us to index new images using visual features only, and also accepting single example images as queries. Experimental evaluations on three different histology image data sets show that our strategy is a simple, yet effective approach to building multimodal representations for histology image search, and outperforms the response of the popular late fusion approach to combine information.

Development and validation of a spectral library searching method for peptide identification from MS/MS.  

PubMed

A notable inefficiency of shotgun proteomics experiments is the repeated rediscovery of the same identifiable peptides by sequence database searching methods, which often are time-consuming and error-prone. A more precise and efficient method, in which previously observed and identified peptide MS/MS spectra are catalogued and condensed into searchable spectral libraries to allow new identifications by spectral matching, is seen as a promising alternative. To that end, an open-source, functionally complete, high-throughput and readily extensible MS/MS spectral searching tool, SpectraST, was developed. A high-quality spectral library was constructed by combining the high-confidence identifications of millions of spectra taken from various data repositories and searched using four sequence search engines. The resulting library consists of over 30,000 spectra for Saccharomyces cerevisiae. Using this library, SpectraST vastly outperforms the sequence search engine SEQUEST in terms of speed and the ability to discriminate good and bad hits. A unique advantage of SpectraST is its full integration into the popular Trans Proteomic Pipeline suite of software, which facilitates user adoption and provides important functionalities such as peptide and protein probability assignment, quantification, and data visualization. This method of spectral library searching is especially suited for targeted proteomics applications, offering superior performance to traditional sequence searching. PMID:17295354

Learning object detectors from online image search  

NASA Astrophysics Data System (ADS)

Being able to detect distinguishable objects is a key component in many high level computer vision applications. Traditional methods for building such detectors require a large amount of carefully collected and cleaned data. For example to build a face detector, a large number of face images need to be collected and faces in each image need to be cropped and aligned as the data for training. This process is tedious and error-pruning. Recently more and more people are sharing their photos on the internet, if we could leverage these data for building a detector, it will save tremendous amount of effort in collecting training data. Popular internet search engines and community photo websites like Google image search, Picassa, Flickr make it possible to harvesting online images for image understanding tasks. In this paper, we develop a method leveraging images obtained from online image search to build an object detector. The proposed method can automatically identify the most distinguishable features across the downloaded images. Using these learned features, a detector can be built to detect the object in a new image. Experiments show promising results of our approach.

Understanding the foundation: the state of generalist search education in library schools as related to the needs of expert searchers in medical libraries  

PubMed Central

Purpose: The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. Setting/Subjects: Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. Methodology: Mixed methods were used, but primarily quantitative bibliometric methods were used. Results: The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. Discussion/Conclusion: While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain.

Improving e-book access via a library-developed full-text search tool*  

PubMed Central

Purpose: This paper reports on the development of a tool for searching the contents of licensed full-text electronic book (e-book) collections. Setting: The Health Sciences Library System (HSLS) provides services to the University of Pittsburgh's medical programs and large academic health system. Brief Description: The HSLS has developed an innovative tool for federated searching of its e-book collections. Built using the XML-based Vivísimo development environment, the tool enables a user to perform a full-text search of over 2,500 titles from the library's seven most highly used e-book collections. From a single “Google-style” query, results are returned as an integrated set of links pointing directly to relevant sections of the full text. Results are also grouped into categories that enable more precise retrieval without reformulation of the search. Results/Evaluation: A heuristic evaluation demonstrated the usability of the tool and a web server log analysis indicated an acceptable level of usage. Based on its success, there are plans to increase the number of online book collections searched. Conclusion: This library's first foray into federated searching has produced an effective tool for searching across large collections of full-text e-books and has provided a good foundation for the development of other library-based federated searching products.

One-encounter search-image formation by araneophagic spiders.  

PubMed

An experimental study of search-image use by araneophagic jumping spiders (i.e., salticid spiders that prey routinely on other spiders) supports five conclusions. First, araneophagic salticids have an innate predisposition to form search images for specific prey from their preferred prey category (spiders) rather than for prey from a non-preferred category (insects). Second, single encounters are sufficient for forming search images. Third, search images are based on selective attention specifically to optical cues. Fourth, there are trade-offs in attention during search-image use (i.e., forming a search image for one type of spider diminishes the araneophagic salticid's attention to other spiders). Fifth, the araneophagic salticid's adoption of search images is costly to the prey (i.e., when the araneophagic salticid adopts a search, the prey's prospects for surviving encounters with the araneophagic salticid are diminished). Cognitive and ecological implications of search-image use are discussed. PMID:15118915

Spline regression hashing for fast image search.  

PubMed

Techniques for fast image retrieval over large databases have attracted considerable attention due to the rapid growth of web images. One promising way to accelerate image search is to use hashing technologies, which represent images by compact binary codewords. In this way, the similarity between images can be efficiently measured in terms of the Hamming distance between their corresponding binary codes. Although plenty of methods on generating hash codes have been proposed in recent years, there are still two key points that needed to be improved: 1) how to precisely preserve the similarity structure of the original data and 2) how to obtain the hash codes of the previously unseen data. In this paper, we propose our spline regression hashing method, in which both the local and global data similarity structures are exploited. To better capture the local manifold structure, we introduce splines developed in Sobolev space to find the local data mapping function. Furthermore, our framework simultaneously learns the hash codes of the training data and the hash function for the unseen data, which solves the out-of-sample problem. Extensive experiments conducted on real image datasets consisting of over one million images show that our proposed method outperforms the state-of-the-art techniques. PMID:22801510

Image search based on quadtree Zernike decomposition  

NASA Astrophysics Data System (ADS)

A novel technique for searching for complex patterns in large multimedia databases is presented, based on rotation independent template matching. To handle objects of arbitrary shape while reducing the computational workload, the pattern to be localized is partitioned into small square blocks of sizes adapted to the local image content using quadtree decomposition. The use of Zernike polynomials for representing each block allows the design of a fast and effective maximum likelihood matching procedure to sequentially verify whether the target image contains each block of the quadtree. State of the art methods usually represent the whole pattern by using an orthogonal basis and extracting an invariant feature vector from the representation coefficients. In the proposed scheme, the use of the quadtree decomposition allows us to bind the number of terms of the truncated expansions, still guaranteeing a precise image representation.

Satisfaction of search experiments in advanced imaging  

NASA Astrophysics Data System (ADS)

The objective of our research is to understand the perception of multiple abnormalities in an imaging examination and to develop strategies for improved diagnostic. We are one of the few laboratories in the world pursuing the goal of reducing detection errors through a better understanding of the underlying perceptual processes involved. Failure to detect an abnormality is the most common class of error in diagnostic imaging and generally is considered the most serious by the medical community. Many of these errors have been attributed to "satisfaction of search," which occurs when a lesion is not reported because discovery of another abnormality has "satisfied" the goal of the search. We have gained some understanding of the mechanisms of satisfaction of search (SOS) traditional radiographic modalities. Currently, there are few interventions to remedy SOS error. For example, patient history that the prompts specific abnormalities, protects the radiologist from missing them even when other abnormalities are present. The knowledge gained from this programmatic research will lead to reduction of observer error.

Image and Its Semantic Role in Search Problem  

NASA Astrophysics Data System (ADS)

The world has now shrunk and information today exists in many forms ranging from text to videos. An overloaded World Wide Web, full of data makes it difficult to extract information from that data and this has given birth to a new phenomenon in the computer industry which is the search engine technology. Image that contains dense information has not yet found its real interpretation over search engines. In this paper we practice application of Semantic Web concepts and propose a standard dimension in image structures in order to improve searching ability in image search engines. An image annotation tool, called "SemImage", was developed which allows users to annotate an image with various ontologies and JPEG was taken as a case-study. This work describes our initial research efforts in semantics-based searching driven by ontological standards for images which we refer to as Image SemSearch.

Development and tuning of an original search engine for patent libraries in medicinal chemistry  

PubMed Central

Background The large increase in the size of patent collections has led to the need of efficient search strategies. But the development of advanced text-mining applications dedicated to patents of the biomedical field remains rare, in particular to address the needs of the pharmaceutical & biotech industry, which intensively uses patent libraries for competitive intelligence and drug development. Methods We describe here the development of an advanced retrieval engine to search information in patent collections in the field of medicinal chemistry. We investigate and combine different strategies and evaluate their respective impact on the performance of the search engine applied to various search tasks, which covers the putatively most frequent search behaviours of intellectual property officers in medical chemistry: 1) a prior art search task; 2) a technical survey task; and 3) a variant of the technical survey task, sometimes called known-item search task, where a single patent is targeted. Results The optimal tuning of our engine resulted in a top-precision of 6.76% for the prior art search task, 23.28% for the technical survey task and 46.02% for the variant of the technical survey task. We observed that co-citation boosting was an appropriate strategy to improve prior art search tasks, while IPC classification of queries was improving retrieval effectiveness for technical survey tasks. Surprisingly, the use of the full body of the patent was always detrimental for search effectiveness. It was also observed that normalizing biomedical entities using curated dictionaries had simply no impact on the search tasks we evaluate. The search engine was finally implemented as a web-application within Novartis Pharma. The application is briefly described in the report. Conclusions We have presented the development of a search engine dedicated to patent search, based on state of the art methods applied to patent corpora. We have shown that a proper tuning of the system to adapt to the various search tasks clearly increases the effectiveness of the system. We conclude that different search tasks demand different information retrieval engines' settings in order to yield optimal end-user retrieval. PMID:24564220

Many universities simply offer their collections to the world via their local web services without being part of any federated system for archiving and even those dissertations that are provided with OAI compliant metadata will not necessarily be picked up by a centralized OAI Ser...

Mediated computer search services relative to instruction services: a survey of one health sciences library.  

PubMed

To assess the quality and usefulness of one health sciences library's mediated computer search service, a survey was undertaken to determine satisfaction rates, why users do or do not use the service, and how useful the service is perceived to be in comparison to instructional service. Satisfaction rates were high, with users indicating librarian expertise and time/cost savings as the main reasons for using the service. Non-users indicated that they preferred to do their own searching, and many were unaware of the service. Though a majority of respondents do not currently use the service, surprisingly a majority of respondents placed significant value on the mediated search service in relation to instruction.

Searching for Pulsars Using Image Pattern Recognition  

NASA Astrophysics Data System (ADS)

In the modern era of big data, many fields of astronomy are generating huge volumes of data, the analysis of which can sometimes be the limiting factor in research. Fortunately, computer scientists have developed powerful data-mining techniques that can be applied to various fields. In this paper, we present a novel artificial intelligence (AI) program that identifies pulsars from recent surveys by using image pattern recognition with deep neural nets—the PICS (Pulsar Image-based Classification System) AI. The AI mimics human experts and distinguishes pulsars from noise and interference by looking for patterns from candidate plots. Different from other pulsar selection programs that search for expected patterns, the PICS AI is taught the salient features of different pulsars from a set of human-labeled candidates through machine learning. The training candidates are collected from the Pulsar Arecibo L-band Feed Array (PALFA) survey. The information from each pulsar candidate is synthesized in four diagnostic plots, which consist of image data with up to thousands of pixels. The AI takes these data from each candidate as its input and uses thousands of such candidates to train its ~9000 neurons. The deep neural networks in this AI system grant it superior ability to recognize various types of pulsars as well as their harmonic signals. The trained AI's performance has been validated with a large set of candidates from a different pulsar survey, the Green Bank North Celestial Cap survey. In this completely independent test, the PICS ranked 264 out of 277 pulsar-related candidates, including all 56 previously known pulsars and 208 of their harmonics, in the top 961 (1%) of 90,008 test candidates, missing only 13 harmonics. The first non-pulsar candidate appears at rank 187, following 45 pulsars and 141 harmonics. In other words, 100% of the pulsars were ranked in the top 1% of all candidates, while 80% were ranked higher than any noise or interference. The performance of this system can be improved over time as more training data are accumulated. This AI system has been integrated into the PALFA survey pipeline and has discovered six new pulsars to date.

Scanners and drillers: Characterizing expert visual search through volumetric images  

PubMed Central

Modern imaging methods like computed tomography (CT) generate 3-D volumes of image data. How do radiologists search through such images? Are certain strategies more efficient? Although there is a large literature devoted to understanding search in 2-D, relatively little is known about search in volumetric space. In recent years, with the ever-increasing popularity of volumetric medical imaging, this question has taken on increased importance as we try to understand, and ultimately reduce, errors in diagnostic radiology. In the current study, we asked 24 radiologists to search chest CTs for lung nodules that could indicate lung cancer. To search, radiologists scrolled up and down through a “stack” of 2-D chest CT “slices.” At each moment, we tracked eye movements in the 2-D image plane and coregistered eye position with the current slice. We used these data to create a 3-D representation of the eye movements through the image volume. Radiologists tended to follow one of two dominant search strategies: “drilling” and “scanning.” Drillers restrict eye movements to a small region of the lung while quickly scrolling through depth. Scanners move more slowly through depth and search an entire level of the lung before moving on to the next level in depth. Driller performance was superior to the scanners on a variety of metrics, including lung nodule detection rate, percentage of the lung covered, and the percentage of search errors where a nodule was never fixated.

A supersecondary structure library and search algorithm for modeling loops in protein structures  

PubMed Central

We present a fragment-search based method for predicting loop conformations in protein models. A hierarchical and multidimensional database has been set up that currently classifies 105?950 loop fragments and loop flanking secondary structures. Besides the length of the loops and types of bracing secondary structures the database is organized along four internal coordinates, a distance and three types of angles characterizing the geometry of stem regions. Candidate fragments are selected from this library by matching the length, the types of bracing secondary structures of the query and satisfying the geometrical restraints of the stems and subsequently inserted in the query protein framework where their fit is assessed by the root mean square deviation (r.m.s.d.) of stem regions and by the number of rigid body clashes with the environment. In the final step remaining candidate loops are ranked by a Z-score that combines information on sequence similarity and fit of predicted and observed ?/? main chain dihedral angle propensities. Confidence Z-score cut-offs were determined for each loop length that identify those predicted fragments that outperform a competitive ab initio method. A web server implements the method, regularly updates the fragment library and performs prediction. Predicted segments are returned, or optionally, these can be completed with side chain reconstruction and subsequently annealed in the environment of the query protein by conjugate gradient minimization. The prediction method was tested on artificially prepared search datasets where all trivial sequence similarities on the SCOP superfamily level were removed. Under these conditions it is possible to predict loops of length 4, 8 and 12 with coverage of 98, 78 and 28% with at least of 0.22, 1.38 and 2.47 ? of r.m.s.d. accuracy, respectively. In a head-to-head comparison on loops extracted from freshly deposited new protein folds the current method outperformed in a ?5:1 ratio an earlier developed database search method. PMID:16617149

Searching for patterns in remote sensing image databases using neural networks  

NASA Technical Reports Server (NTRS)

We have investigated a method, based on a successful neural network multispectral image classification system, of searching for single patterns in remote sensing databases. While defining the pattern to search for and the feature to be used for that search (spectral, spatial, temporal, etc.) is challenging, a more difficult task is selecting competing patterns to train against the desired pattern. Schemes for competing pattern selection, including random selection and human interpreted selection, are discussed in the context of an example detection of dense urban areas in Landsat Thematic Mapper imagery. When applying the search to multiple images, a simple normalization method can alleviate the problem of inconsistent image calibration. Another potential problem, that of highly compressed data, was found to have a minimal effect on the ability to detect the desired pattern. The neural network algorithm has been implemented using the PVM (Parallel Virtual Machine) library and nearly-optimal speedups have been obtained that help alleviate the long process of searching through imagery.

Target image search using fMRI signals  

NASA Astrophysics Data System (ADS)

Recent neural signal decoding studies based on functional magnetic resonance imaging (fMRI) have identified the specific image presenting to the subject from a set of potential images, and some studies extend neural decoding into image reconstruction, i.e. image contents that the subject perceived were decoded from the fMRI signals recorded during the subject looking at images. In this paper, we decoded the target images using fMRI signals and described a target image searching method based on the relationship between target image stimuli and fMRI activity. We recorded fMRI data during a serial visual stimuli image presentation task, some of the stimuli images were target images and the rest images were non-target ones. Our fMRI data analysis results showed that in the serial visual presentation task, target images elicited a stereotypical response in the fMRI, which can be detected by multi-voxel pattern analysis (MVPA). Classifiers designed with support vector machine (SVM) used this response to decipher target images from non-target images. The leave-one-run-out cross-validation showed that we can pick out the target images with a possibility far above the chance level, which indicate that there's a neural signatures correlated with the target image recognition process in the human systems.

Retrieving and Ranking Unannotated Images through Collaboratively Mining Online Search Results  

SciTech Connect

We present a new image search and ranking algorithm for retrieving unannotated images by collaboratively mining online search results, which consist of online image and text search results. The online image search results are leveraged as reference examples to perform content-based image search over unannotated images. The online text search results are utilized to estimate individual reference images relevance to the search query as not all the online image search results are closely related to the query. Overall, the key contribution of our method lies in its capability to deal with unreliable online image search results through jointly mining visual and textual aspects of online search results. Through such collaborative mining, our algorithm infers the relevance of an online search result image to a text query. Once we estimate a query relevance score for each online image search result, we can selectively use query specific online search result images as reference examples for retrieving and ranking unannotated images. To explore the performance of our algorithm, we tested our algorithm both on the standard public image datasets and several modest sized personal photo collections. We also compared the performance of our method with that of two peer methods. The results are very positive, indicating that our algorithm is superior to existing content-based image search algorithms for retrieving and ranking unannotated images. Overall, the main advantage of our algorithm comes from its collaborative mining over online search results both in the visual and textual domains.

Search and detection modeling of military imaging systems  

NASA Astrophysics Data System (ADS)

For more than 50 years, the U.S. Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate (NVESD) has been studying the science behind the human processes of searching and detecting, and using that knowledge to develop and refine its models for military imaging systems. Modeling how human observers perform military tasks while using imaging systems in the field and linking that model with the physics of the systems has resulted in the comprehensive sensor models we have today. These models are used by the government, military, industry, and academia for sensor development, sensor system acquisition, military tactics development, and war-gaming. From the original hypothesis put forth by John Johnson in 1958, to modeling time-limited search, to modeling the impact of motion on target detection, to modeling target acquisition performance in different spectral bands, the concept of search has a wide-ranging history. Our purpose is to present a snapshot of that history; as such, it will begin with a description of the search-modeling task, followed by a summary of highlights from the early years, and concluding with a discussion of search and detection modeling today and the changing battlefield. Some of the topics to be discussed will be classic search, clutter, computational vision models and the ACQUIRE model with its variants. We do not claim to present a complete history here, but rather a look at some of the work that has been done, and this is meant to be an introduction to an extensive amount of work on a complex topic. That said, it is hoped that this overview of the history of search and detection modeling of military imaging systems pursued by NVESD directly, or in association with other government agencies or contractors, will provide both the novice and experienced search modeler with a useful historical summary and an introduction to current issues and future challenges.

Rebels in search of champions: Envisioning the library of the future  

SciTech Connect

The traditional role of librarians to secure and provide access to the archives of recorded knowledge is being rapidly challenged on three fronts: the increasing technical sophistication of library users, the wide availability of information management software, and economic pressures on the growth of library collections. While we may argue endlessly about turf'' and ownership'', the real challenge is to forge a new ethic of librarianship which defies the stereotype of the passive provider of information services, explores new models of partnership with users, and champions an interactive environment in which to create the library of the future. The Main Library at Lawrence Livermore National Laboratory is actively engaged in testing experimental models of the library of the future, centered on dynamic user-librarian interactions, versatile information technologies, and on forecasting creative partnerships with library users in different environments. These experiments are described, evaluated, and their implications for future development are explored. 39 refs.

Library of Virginia: Photographic Collections  

NSDL National Science Digital Library

The Library of Virginia's ongoing Digital Library Program in 2001 added eight public library digital photograph collections. Starting from the LVA Digital Library homepage, users select the name of one of the public library collections to go directly to its search page. For a little more information about the type of photographs to expect in each collection, we recommend beginning at the About the Collections page. Following this route, a user can learn that the digitized portion of the Hampton Public Library consists of 1,400 photographs from the Christopher E. Cheyne collection, including many downtown Hampton businesses, representing the seafood industry hotels and seaside resorts, and the amusement park. This collection also includes portraits of a few Civil War veterans, members of prominent Hampton families, and photographer Cheyne's family. In contrast, one would find fewer images of people in the Newport News Public Library collection, since it consists of close to 300 images related to the construction of Hilton Village, a World War I era public housing project, and the Hotel Warwick, a grand nineteenth-century resort. Searching is still a little unpredictable even with the additional information; to browse most of the images in a collection, try searching on a photographer's name, or the proper name of prominent subjects depicted.

A 3D metal artifact correction method in cone-beam CT bone imaging by using an implant image library  

NASA Astrophysics Data System (ADS)

Cone-beam CT (CBCT) technique has been used by orthopedists to monitor bone graft growth after orthopedic surgery. In order to correct severe metal artifacts in reconstructed images caused by metal implants used in bone grafting, a three-dimensional metal artifact correction method has been previously proposed. The implants' mathematic boundaries were generated to help to segment metal from reconstructed images. The segmented metal implants were forward-projected onto the detector to create metal-only projections to compensate for beam-hardening effect. This method was proved effective with the metal implants of regular shape which can be simulated by simple 3D primitives, such as cuboid, cylinder and cone. But for metal implants of arbitrary shape, their boundaries are difficult to define mathematically. To solve this problem, this paper proposed a method by setting up an implant image library and using the implants' a priori shape information from the library during the artifact correction. The implants were acquired and scanned before the surgery and their a priori information were stored in a library. During the artifact correction, the library was called to provide the shape information of the implants to help to do the implant segmentation. The segmented implants were forward-projected onto the detector to generate implant-only projections by a cone-beam forward-projection technique. Beam-hardening effect in the original projections was then compensated by high polynomial orders of implant projections. Finally, the corrected projections were back-projected to produce artifacts-reduced images. Both phantom studies and patient studies were conducted to test this correction method. Results from both studies show the artifacts have been greatly reduced and the accuracy of bone volume measurement has been increased.

Monitoring of HTS compound library quality via a high-resolution image acquisition and processing instrument.  

PubMed

This report presents the high-resolution image acquisition and processing instrument for compound management applications (HIAPI-CM). The HIAPI-CM combines imaging spectroscopy and machine-vision analysis to perform rapid assessment of high-throughput screening (HTS) compound library quality. It has been customized to detect and classify typical artifacts found in HTS compound library microtiter plates (MTPs). These artifacts include (1) insufficient volume of liquid compound sample, (2) compound precipitation, and (3) colored compounds that interfere with HTS assay detection format readout. The HIAPI-CM is also configured to automatically query and compare its analysis results to data stored in a LIMS or corporate database, aiding in the detection of compound registration errors. To demonstrate its capabilities, several compound plates (n=5760 wells total) containing different artifacts were measured via automated HIAPI-CM analysis, and results compared with those obtained by manual (visual) inspection. In all cases, the instrument demonstrated high fidelity (99.8% empty wells; 100.1% filled wells; 94.4% for partially filled wells; 94.0% for wells containing colored compounds), and in the case of precipitate detection, the HIAPI-CM results significantly exceeded the fidelity of visual observations (220.0%). As described, the HIAPI-CM allows for noninvasive, nondestructive MTP assessment with a diagnostic throughput of about 1min per plate, reducing analytical expenses and improving the quality and stewardship of HTS compound libraries.

HSI-Find: A Visualization and Search Service for Terascale Spectral Image Catalogs  

NASA Astrophysics Data System (ADS)

Imaging spectrometers are remote sensing instruments commonly deployed on aircraft and spacecraft. They provide surface reflectance in hundreds of wavelength channels, creating data cubes known as hyperspecrtral images. They provide rich compositional information making them powerful tools for planetary and terrestrial science. These data products can be challenging to interpret because they contain datapoints numbering in the thousands (Dawn VIR) or millions (AVIRIS-C). Cross-image studies or exploratory searches involving more than one scene are rare; data volumes are often tens of GB per image and typical consumer-grade computers cannot store more than a handful of images in RAM. Visualizing the information in a single scene is challenging since the human eye can only distinguish three color channels out of the hundreds available. To date, analysis has been performed mostly on single images using purpose-built software tools that require extensive training and commercial licenses. The HSIFind software suite provides a scalable distributed solution to the problem of visualizing and searching large catalogs of spectral image data. It consists of a RESTful web service that communicates to a javascript-based browser client. The software provides basic visualization through an intuitive visual interface, allowing users with minimal training to explore the images or view selected spectra. Users can accumulate a library of spectra from one or more images and use these to search for similar materials. The result appears as an intensity map showing the extent of a spectral feature in a scene. Continuum removal can isolate diagnostic absorption features. The server-side mapping algorithm uses an efficient matched filter algorithm that can process a megapixel image cube in just a few seconds. This enables real-time interaction, leading to a new way of interacting with the data: the user can launch a search with a single mouse click and see the resulting map in seconds. This allows the user to quickly explore each image, ascertain the main units of surface material, localize outliers, and develop an understanding of the various materials' spectral characteristics. The HSIFind software suite is currently in beta testing at the Planetary Science Institute and a process is underway to release it under an open source license to the broader community. We believe it will benefit instrument operations during remote planetary exploration, where tactical mission decisions demand rapid analysis of each new dataset. The approach also holds potential for public spectral catalogs where its shallow learning curve and portability can make these datasets accessible to a much wider range of researchers.

Establishment of a search library about benzylisoquinoline alkaloids based on selective separation on the binaphthyl column and standard analysis on C18 column.  

PubMed

A search library about benzylisoquinoline alkaloids was established based on preparation of alkaloid fractions from Rhizoma coptidis, Cortex phellodendri, and Rhizoma corydalis. In this work, two alkaloid fractions from each herbal medicine were first prepared based on selective separation on the "click" binaphthyl column. And then these alkaloid fractions were analyzed on C18 column by liquid chromatography coupled with tandem mass spectrometry. Many structure-related compounds were included in these alkaloids fractions, which led to easy separation and good MS response in further work. Therefore, a search library of 52 benzylisoquinoline alkaloids was established, which included eight aporphine, 19 tetrahydroprotoberberine, two protopine, two benzyltetrahydroisoquinoline, and 21 protoberberine alkaloids. The information of the search library contained compound names, structures, retention times, accurate masses, fragmentation pathways of benzylisoquionline alkaloids, and their sources from three herbal medicines. Using such a library, the alkaloids, especially those trace and unknown components in some herbal medicine could be accurately and quickly identified. In addition, the distribution of benzylisoquinoline alkaloids in the herbal medicines could be also summarized by searching the source samples in the library. PMID:23109405

There are some surprisingly modern images in the stereograph collection, such as a 1978 Karem Abdul Jabbar slam dunk, and a 1930 stereograph portrait of Huey Long. The search interface for both databases is the same, allowing keyword searches or browsing by titles, creators, or subjects. In the browse mode, images are presented as pages of five thumbnails. This simple arrangement is missing some navigational tools; when browsing, there is no way to get back to the beginning without hitting the back button repeatedly; after search results are displayed, it is difficult to do a new search without going all the way back to the LSU Digital Library homepage.

A new image stabilization algorithm based on improved diamond search combined with adaptive partitioning optimization  

NASA Astrophysics Data System (ADS)

Since the traditional block matching method in the larger search window tend to fall into local optimum to be unsuitable solving large pan shake image stabilization problem, a new image stabilization algorithm is proposed, which is still based on diamond search, but the pattern of large template is modified to ring, search domain is partitioned and sorted by size, global motion vector is extracted through maximum sample statistics and compensated through adaptive mean filter. A numerical example is calculated to show that the method has a higher search efficiency than exhaustive search, three-step search, four-step search and traditional diamond search; maximum sample statistics avoid the prospect's interference effectively when global motion vectors is extracted; adaptive filter compensation has better real-time and smoothness than a fixed size one; PSNR of images after processed is higher significantly than the one before processed. Therefore the results above verify the accuracy of the algorithm and feasibility.

Direct Imaging Searches with the Apodizing Phase Plate Coronagraph  

NASA Astrophysics Data System (ADS)

The sensitivity of direct imaging searches for extrasolar planets is limited by the presence of diffraction rings from the primary star. Coronagraphs are angular filters that minimise these diffraction structures whilst allowing light from faint companions to shine through. The Apodizing Phase Plate (APP; Kenworthy 2007) coronagraph is a simple pupil plane optic that suppresses diffraction over a 180 degree region around each star simultaneously, providing easy beam switching observations and requiring no time consuming optical alignment at the telescope. We will present our results on using the APP at the Very Large Telescope in surveys for extrasolar planets around A/F and debris disk hosting stars in the L' band (3.8 microns) in the Southern Hemisphere, where we reach a contrast of 12 magnitudes at 0.5 arcseconds (Meshkat 2013). In Leiden, we are also developing the next generation of broadband achromatic coronagraphs that can simultaneously image both sides of the star using Vector APPs (Snik 2012, Otten 2012). Recent laboratory results showing the potential of this technology for future ELTs will also be presented.

SearchSmallRNA: a graphical interface tool for the assemblage of viral genomes using small RNA libraries data  

PubMed Central

Background Next-generation parallel sequencing (NGS) allows the identification of viral pathogens by sequencing the small RNAs of infected hosts. Thus, viral genomes may be assembled from host immune response products without prior virus enrichment, amplification or purification. However, mapping of the vast information obtained presents a bioinformatics challenge. Methods In order to by pass the need of line command and basic bioinformatics knowledge, we develop a mapping software with a graphical interface to the assemblage of viral genomes from small RNA dataset obtained by NGS. SearchSmallRNA was developed in JAVA language version 7 using NetBeans IDE 7.1 software. The program also allows the analysis of the viral small interfering RNAs (vsRNAs) profile; providing an overview of the size distribution and other features of the vsRNAs produced in infected cells. Results The program performs comparisons between each read sequenced present in a library and a chosen reference genome. Reads showing Hamming distances smaller or equal to an allowed mismatched will be selected as positives and used to the assemblage of a long nucleotide genome sequence. In order to validate the software, distinct analysis using NGS dataset obtained from HIV and two plant viruses were used to reconstruct viral whole genomes. Conclusions SearchSmallRNA program was able to reconstructed viral genomes using NGS of small RNA dataset with high degree of reliability so it will be a valuable tool for viruses sequencing and discovery. It is accessible and free to all research communities and has the advantage to have an easy-to-use graphical interface.

Visual Search with Image Modification in Age-Related Macular Degeneration  

PubMed Central

Purpose. AMD results in loss of central vision and a dependence on low-resolution peripheral vision. While many image enhancement techniques have been proposed, there is a lack of quantitative comparison of the effectiveness of enhancement. We developed a natural visual search task that uses patients' eye movements as a quantitative and functional measure of the efficacy of image modification. Methods. Eye movements of 17 patients (mean age = 77 years) with AMD were recorded while they searched for target objects in natural images. Eight different image modification methods were implemented and included manipulations of local image or edge contrast, color, and crowding. In a subsequent task, patients ranked their preference of the image modifications. Results. Within individual participants, there was no significant difference in search duration or accuracy across eight different image manipulations. When data were collapsed across all image modifications, a multivariate model identified six significant predictors for normalized search duration including scotoma size and acuity, as well as interactions among scotoma size, age, acuity, and contrast (P < 0.05). Additionally, an analysis of image statistics showed no correlation with search performance across all image modifications. Rank ordering of enhancement methods based on participants' preference revealed a trend that participants preferred the least modified images (P < 0.05). Conclusions. There was no quantitative effect of image modification on search performance. A better understanding of low- and high-level components of visual search in natural scenes is necessary to improve future attempts at image enhancement for low vision patients. Different search tasks may require alternative image modifications to improve patient functioning and performance. PMID:22930725

A geometry-based image search engine for advanced RADARSAT-1/2 GIS applications  

NASA Astrophysics Data System (ADS)

Space-borne Synthetic Aperture Radar (SAR) sensors, such as RADARSAT-1 and -2, enable a multitude of defense and security applications owing to their unique capabilities of cloud penetration, day/night imaging and multi-polarization imaging. As a result, advanced SAR image time series exploitation techniques such as Interferometric SAR (InSAR) and Radargrammetry are now routinely used in applications such as underground tunnel monitoring, infrastructure monitoring and DEM generation. Imaging geometry, as determined by the satellite orbit and imaged terrain, plays a critical role in the success of such techniques. This paper describes the architecture and the current status of development of a geometry-based search engine that allows the search and visualization of archived and future RADARSAT-1 and -2 images appropriate for a variety of advanced SAR techniques and applications. Key features of the search engine's scalable architecture include (a) Interactive GIS-based visualization of the search results; (b) A client-server architecture for online access that produces up-to-date searches of the archive images and that can, in future, be extended to acquisition planning; (c) A techniquespecific search mode, wherein an expert user explicitly sets search parameters to find appropriate images for advanced SAR techniques such as InSAR and Radargrammetry; (d) A future application-specific search mode, wherein all search parameters implicitly default to preset values according to the application of choice such as tunnel monitoring, DEM generation and deformation mapping; (f) Accurate baseline calculations for InSAR searches, and, optimum beam configuration for Radargrammetric searches; (g) Simulated quick look images and technique-specific sensitivity maps in the future.

A survey of medical students on the impact of a new digital imaging library in the dissection room.  

PubMed

Radiology has a recognised role in undergraduate anatomy education. The recent digitalisation of radiology has created new learning opportunities involving techniques such as image labelling, 3D reconstruction, and multiplanar reformatting. An opportunity was identified at the University of Nottingham to create a digital library of normal radiology images as a learner-driven adjunct in anatomy dissection sessions. We describe the process of creating a de novo digital library by sourcing images for presentation at computer workstations. Students' attitudes towards this new resource were assessed using a questionnaire which used a 5 point Likert scale and also offered free text responses. One hundred and forty-one out of 260 students (54%) completed the questionnaire. The most notable findings were: a positive response to the relevance of imaging to the session topics (median score 4), strong agreement that images should be available on the university website (median score 5), and disagreement that enough workstations were available (median score 2). About 24% of respondents suggested independently that images needed more labeling to help with orientation and identification. This first phase of supplying a comprehensive imaging library can be regarded as a success. Increasing availability and incorporating dynamic labeling are well recognized as important design concepts for electronic learning resources and these will be improved in the second phase of delivery as a direct result of student feedback. Hopefully other centers can benefit from this experience and will consider such a venture to be worthwhile. PMID:19637297

[Value of automated medical indexing of an image database and a digital radiological library].  

PubMed

We indexed the contents of a radiology server on the web to facilitate access to research documents and to link reference texts to images contained in radiology databases. Indexation also allows case reports to be transformed with no supplementary work into formats compatible with computer-assisted training. Indexation was performed automatically by ADM-Index, the aim being to identify the medical concepts expressed within each medical text. Two types of texts were indexed: medical imaging reference books (Edicerf) and case reports with illustrations and captions (Iconocerf). These documents are now available on a web server with HTML format for Edicerf and on an Oracle database for Iconocerf. When the user consults a chapter of a book or a case report, the indexed terms are displayed in the heading; all reference texts and case reports containing the indexed terms can then be called up instantaneously. The user can express his search in natural language. Indexation follows the same process allowing instantaneous recall of all reference texts and case reports where the same concept appears in the diagnosis or clinical context. By using the context of the case reports as the search index, all case reports involving a common medical concept can be found. The context is interpreted as a question. When the user responds to this question, ADM-Index compares this response with the answer furnished by the reference texts and case reports. Correct or erroneous responses can thus be identified, converting the system into a computer-assisted training tool. PMID:9239347

Simultaneous screening of targeted and non-targeted contaminants using an LC-QTOF-MS system and automated MS/MS library searching.  

PubMed

Simultaneous high-resolution full-scan and tandem mass spectrometry (MS/MS) analysis using time of flight mass spectrometry brings an answer for increasing demand of retrospective and non-targeted data analysis. Such analysis combined with spectral library searching is a promising tool for targeted and untargeted screening of small molecules. Despite considerable extension of the panel of compounds of tandem mass spectral libraries, the heterogeneity of spectral data poses a major challenge against the effective usage of spectral libraries. Performance evaluation of available LC-MS/MS libraries will significantly increase credibility in the search results. The present work was aimed to evaluate fluctuation of MS/MS pattern, in the peak intensities distribution together with mass accuracy measurements, and in consequence, performance compliant with ion ratio and mass error criteria as principles in identification processes for targeted and untargeted contaminants at trace levels. Matrix effect and ultra-trace levels of concentration (from 50?ng?l(-1) to 1000?ng?l(-1) were evaluated as potential source of inaccuracy in the performance of spectral matching. Matrix-matched samples and real samples were screened for proof of applicability. By manual review of data and application of ion ratio and ppm error criteria, false negatives were obtained; this number diminished when in-house library was used, while with on-line MS/MS databases 100% of positive samples were found. In our experience, intensity of peaks across spectra was highly correlated to the concentration effect and matrix complexity. In turn, analysis of spectra acquired at trace concentrations and in different matrices results in better performance in providing correct and reliable identification. PMID:25230185

Library Literature: Redesigning Library Services: A Manifesto  

NSDL National Science Digital Library

The Berkeley Digital Library SunSITE (discussed in the February 9, 1996 Scout Report) has added the first in what will be a series of library literature, Michael Buckland's Redesigning Library Services: A Manifesto. Buckland argues against what he sees as library literature's over-emphasis on technology for technology's sake, "on means, rather than on ends, and tactics rather than strategy." Though electronic library management has certainly changed and grown since Redesigning Library Services was first published (1992), the book's primary emphasis on the goals and purposes of library services still serves as a relevant touchstone. Buckland's book is meant to countervail against the fact that "there is so much more written, for example, on how to build collections than on the roles that collections play." The text can be read online, downloaded (.pdf), or searched for keywords (Note that searches return only links to chapters, not passages of text).

A Fieldable-Prototype Large-Area Gamma-ray Imager for Orphan Source Search  

SciTech Connect

We have constructed a unique instrument for use in the search for orphan sources. The system uses gamma-ray imaging to "see through" the natural background variations that effectively limit the search range of normal devices to ~10 m. The imager is mounted in a 4.9- m-long trailer and can be towed by a large personal vehicle. Source locations are determined both in range and along the direction of travel as the vehicle moves. A fully inertial platform coupled to a Global Positioning System receiver is used to map the gamma-ray images onto overhead geospatial imagery. The resulting images provide precise source locations, allowing rapid follow-up work. The instrument simultaneously searches both sides of the street to a distance of 50 m (100-m swath) for milliCurieclass sources with near-perfect performance.

Using Gravitational Imaging to Search for Substructure in Distant Galaxies  

NASA Astrophysics Data System (ADS)

In this talk I will show how the powerful combination of gravitational lensing and sensitive, high-resolution imaging can provide direct observational tests of galaxy formation scenarios under the cold dark matter paradigm. In particular, I will discuss how we can use the technique of "gravitational imaging" to place observational constraints on the subhalo mass function. With this method we are, for the first time, directly measuring masses of galaxy satellites well outside of the Local Group. These measurements can be made even if the satellites are composed purely of dark matter, and provide an excellent complement to information obtained from investigations of Milky Way satellite galaxies. The imaging used for the project that I will discuss comes from Keck adaptive optics (AO) and Hubble Space Telescope (HST) observations. In some cases the AO imaging is clearly sharper than that obtained with HST.

Search performance with discrete-cell stimulus arrays: filtered naturalistic images and probabilistic markers.  

PubMed

In order to partially fill the gap between search studies with artificial and naturalistic stimuli, experiments with segmented and spatially filtered images of real stimuli in the discrete cells of search arrays were conducted. RT × set size functions obtained with the spatially filtered arrays were compared with those obtained with geometric and other types of arrays. With the aid of Fourier analysis, components of target certainty/uncertainty, target-distractor similarity/dissimilarity, and distractor homogeneity/heterogeneity were evaluated for their effects on search performance and efficiency. The comparative effects of valid/invalid and ambiguous/unambiguous markers of search items were included in the experiments to probe the potential contributions of top-down and bottom-up control to search with naturalistic stimuli. Visual coding in the form of spatial frequency passbands and top-down preferences for distractor search were used to explain the results. PMID:22476358

Intelligent technique to search for patterns within images in massive databases  

SciTech Connect

An image retrieval system for JET has been developed. The image database contains the images of the JET high speed visible camera. The system input is a pattern selected inside an image and the output is the group of frames (defined by their discharge numbers and time slices) that show patterns similar to the selected one. This approach is based on morphological pattern recognition and it should be emphasized that the pattern is found independently of its location in the frame. The technique encodes images into characters and, therefore, it transforms the pattern search into a character-matching problem.

NASA Astrophysics Data System (ADS)

We propose to survey 11 nearby galaxies with XMM to search for new ultraluminous X-ray sources (ULXs). Most ULXs are associated with star formation and are likely stellar mass black holes in super-Eddington accretion states or with mildly beamed emission. Some of the strongest intermediate mass black hole (IMBH) candidates are found in galaxies with low star formation rates (SFRs). Our survey will sample late-type galaxies with low SFRs that lack deep X-ray data but are covered by archival Hubble Space Telescope observations enabling us to identify optical counterparts and study the surrounding environments.

A neotropical Miocene pollen database employing image-based search and semantic modeling1  

PubMed Central

• Premise of the study: Digital microscopic pollen images are being generated with increasing speed and volume, producing opportunities to develop new computational methods that increase the consistency and efficiency of pollen analysis and provide the palynological community a computational framework for information sharing and knowledge transfer. • Methods: Mathematical methods were used to assign trait semantics (abstract morphological representations) of the images of neotropical Miocene pollen and spores. Advanced database-indexing structures were built to compare and retrieve similar images based on their visual content. A Web-based system was developed to provide novel tools for automatic trait semantic annotation and image retrieval by trait semantics and visual content. • Results: Mathematical models that map visual features to trait semantics can be used to annotate images with morphology semantics and to search image databases with improved reliability and productivity. Images can also be searched by visual content, providing users with customized emphases on traits such as color, shape, and texture. • Discussion: Content- and semantic-based image searches provide a powerful computational platform for pollen and spore identification. The infrastructure outlined provides a framework for building a community-wide palynological resource, streamlining the process of manual identification, analysis, and species discovery.

'Function-first' Lead Discovery: Mode of Action Profiling of Natural Product Libraries Using Image-Based Screening  

PubMed Central

Summary Cytological profiling is a high-content image-based screening technology that provides insight into the mode of action (MOA) for test compounds by directly measuring hundreds of phenotypic cellular features. We have extended this recently reported technology to the mechanistic characterization of unknown natural products libraries for the direct prediction of compound MOAs at the primary screening stage. By analyzing a training set of commercial compounds of known mechanism and comparing these profiles to those obtained from natural product library members, we have successfully annotated extracts based on mode of action, dereplicated known compounds based on biological similarity to the training set, and identified and predicted the MOA of a family of new iron siderophores. Coupled with traditional analytical techniques, cytological profiling provides a new avenue for the creation of ‘function-first’ platforms for natural products discovery. PMID:23438757

The local search is applied to some top elites with the best fitnesses in the new generation. The best fitness is searched between some positions selected near the elite position. Individual recognition experiment using the ear image with the uncertain data was carried out in respect of the method. As the result, it is noted that the registrant recognition rate was 100 percent, and it became 100 percent, at the un-registrant denial rate.

Leveraging Open Standards and Technologies to Search and Display Planetary Image Data  

NASA Astrophysics Data System (ADS)

Mars and the Moon have both been visited by multiple NASA spacecraft. A large number of images and other data have been gathered by the spacecraft and are publicly available in NASA's Planetary Data System. Through a collaboration with Google, Inc., the User Centered Technologies group at NASA Ames Resarch Center has developed at tool for searching and browsing among images from multiple Mars and Moon missions. Development of this tool was facilitated by the use of several open technologies and standards. First, an open-source full-text search engine is used to search both place names on the target and to find images matching a geographic region. Second, the published API of the Google Earth browser plugin is used to geolocate the images on a virtual globe and allow the user to navigate on the globe to see related images. The structure of the application also employs standard protocols and services. The back-end is exposed as RESTful APIs, which could be reused by other client systems in the future. Further, the communication between the front- and back-end portions of the system utilizes open data standards including XML and KML (Keyhole Markup Language) for representation of textual and geographic data. The creation of the search index was facilitated by reuse of existing, publicly available metadata, including the Gazetteer of Planetary Nomenclature from the USGS, available in KML format. And the image metadata was reused from standards-compliant archives in the Planetary Data System. The system also supports collaboration with other tools by allowing export of search results in KML, and the ability to display those results in the Google Earth desktop application. We will demonstrate the search and visualization capabilities of the system, with emphasis on how the system facilitates reuse of data and services through the adoption of open standards.

Orbital Imaging Radar and the Search for Water on Mars  

NASA Technical Reports Server (NTRS)

The surface of Mars has been modified by a range of geologic processes, and many regions are mantled by varying depths of wind-blown dust, volcanic ash, and fluvially deposited or other water-lain sediments. We are proposing an orbital mission carrying a synthetic aperture radar (SAR) that can penetrate a significant depth of overlying material to reveal the detailed geomorphology as it relates to the changing fluvial, eolian, volcanic, and cratering history of Mars. Moreover, the data to be returned are of direct relevance to the search for past and present occurrences of liquid water, life, changing martian climate, and geologic history (e.g., origin of the northern plains, mechanisms for past and possible present valley formation, and genesis of widespread mantling deposits), the validation of potential landing sites for rover safety, and evaluation of sub-surface accessibility for drilling.

Search algorithm complexity modeling with application to image alignment and matching  

NASA Astrophysics Data System (ADS)

Search algorithm complexity modeling, in the form of penetration rate estimation, provides a useful way to estimate search efficiency in application domains which involve searching over a hypothesis space of reference templates or models, as in model-based object recognition, automatic target recognition, and biometric recognition. The penetration rate quantifies the expected portion of the database that must be searched, and is useful for estimating search algorithm computational requirements. In this paper we perform mathematical modeling to derive general equations for penetration rate estimates that are applicable to a wide range of recognition problems. We extend previous penetration rate analyses to use more general probabilistic modeling assumptions. In particular we provide penetration rate equations within the framework of a model-based image alignment application domain in which a prioritized hierarchical grid search is used to rank subspace bins based on matching probability. We derive general equations, and provide special cases based on simplifying assumptions. We show how previously-derived penetration rate equations are special cases of the general formulation. We apply the analysis to model-based logo image alignment in which a hierarchical grid search is used over a geometric misalignment transform hypothesis space. We present numerical results validating the modeling assumptions and derived formulation.

An Iterative Framework for EEG-based Image Search: Robust Retrieval with Weak Classifiers  

PubMed Central

We revisit the framework for brain-coupled image search, where the Electroencephalography (EEG) channel under rapid serial visual presentation protocol is used to detect user preferences. Extending previous works on the synergy between content-based image labeling and EEG-based brain-computer interface (BCI), we propose a different perspective on iterative coupling. Previously, the iterations were used to improve the set of EEG-based image labels before propagating them to the unseen images for the final retrieval. In our approach we accumulate the evidence of the true labels for each image in the database through iterations. This is done by propagating the EEG-based labels of the presented images at each iteration to the rest of images in the database. Our results demonstrate a continuous improvement of the labeling performance across iterations despite the moderate EEG-based labeling (AUC <75%). The overall analysis is done in terms of the single-trial EEG decoding performance and the image database reorganization quality. Furthermore, we discuss the EEG-based labeling performance with respect to a search task given the same image database. PMID:23977196

Cathodoluminescence : an imaging technique for the search of extraterrestrial life  

NASA Astrophysics Data System (ADS)

Solids irradiated by a 10-20 keV electron beam emit ligth in the UV-visible range, which is called cathodoluminescence (CL). CL imagery is a powerful tool for visualizing minerals and their internal structures (lattice defects, zoning). For example, terrestrial calcite, either of sedimentary or biogenic origin, often display a bright orange CL, as a result of the incorporation of trace Mn2+ in its lattice. Aragonite can also be discriminated from calcite by its green CL. Carbonates are a major target for the search of life on Mars, and CL imagery could contribute to reveal carbonates in situ. Thomas et al. [1] have validated the concept of an electron lamp to make CL imagery of a rock surface placed in a martian CO2 atmosphere. We present 2 examples of terrestrial bacterial microstructures that are revealed by CL. (1) In Sinemurian sediments from the Montmiral borehole (Valence Basin, France), banded wavy calcite in contact with pyrite represents fossilized biofilms of sulfato-reducing bacteria, as confirmed by the sulfur isotopic composition of pyrite ~+36 %0 PDB. (2) At l'Ile Crémieux, north of the Valence basin, a dense filamentous microbial/fungal community with a bright orange CL signature is embedded in vuggy calcite from a tectonic vein. The mat is anchored 1-2 mm deep in the oolitic veinwall and emerges at right angle in the 'open' fracture space. Finally, carbonate vesicles and exhalite crusts from the Svalbard basalt in Groendland, with orange CL, are shown as analogues to carbonates from the martian ALH84001 igneous meteorite.

Cuckoo search algorithm based satellite image contrast and brightness enhancement using DWT-SVD.  

PubMed

This paper presents a new contrast enhancement approach which is based on Cuckoo Search (CS) algorithm and DWT-SVD for quality improvement of the low contrast satellite images. The input image is decomposed into the four frequency subbands through Discrete Wavelet Transform (DWT), and CS algorithm used to optimize each subband of DWT and then obtains the singular value matrix of the low-low thresholded subband image and finally, it reconstructs the enhanced image by applying IDWT. The singular value matrix employed intensity information of the particular image, and any modification in the singular values changes the intensity of the given image. The experimental results show superiority of the proposed method performance in terms of PSNR, MSE, Mean and Standard Deviation over conventional and state-of-the-art techniques. PMID:24893835

MapReduce Implementation of a Hybrid Spectral Library-Database Search Method for Large-Scale Peptide Identification  

SciTech Connect

A MapReduce-based implementation called MR- MSPolygraph for parallelizing peptide identification from mass spectrometry data is presented. The underlying serial method, MSPolygraph, uses a novel hybrid approach to match an experimental spectrum against a combination of a protein sequence database and a spectral library. Our MapReduce implementation can run on any Hadoop cluster environment. Experimental results demonstrate that, relative to the serial version, MR-MSPolygraph reduces the time to solution from weeks to hours, for processing tens of thousands of experimental spectra. Speedup and other related performance studies are also reported on a 400-core Hadoop cluster using spectral datasets from environmental microbial communities as inputs.

Image search reranking with query-dependent click-based relevance feedback.  

PubMed

Our goal is to boost text-based image search results via image reranking. There are diverse modalities (features) of images that we can leverage for reranking, however, the effects of different modalities are query-dependent. The primary challenge we face is how to fuse multiple modalities adaptively for different queries, which has often been overlooked in previous reranking research. Moreover, multimodality fusion without an understanding of the query is risky, and may lead to incorrect judgment in reranking. Therefore, to obtain the best fusion weights for the query, in this paper, we leverage click-through data, which can be viewed as an "implicit" user feedback and an effective means of understanding the query. A novel reranking algorithm, called click-based relevance feedback, is proposed. This algorithm emphasizes the successful use of click-through data for identifying user search intention, while leveraging multiple kernel learning algorithm to adaptively learn the query-dependent fusion weights for multiple modalities. We conduct experiments on a real-world data set collected from a commercial search engine with click-through data. Encouraging experimental results demonstrate that our proposed reranking approach can significantly improve the NDCG@10 of the initial search results by 11.62%, and can outperform several existing approaches for most kinds of queries, such as tail, middle, and top queries.

The impact of complaint management and service quality on organizational image: A case study at the Malaysian public university library  

NASA Astrophysics Data System (ADS)

Service failure frequently occurs. This affects customer expectations which lead to complaint. However, not all dissatisfied customers actually complain. Without customer feedback, it would be impossible for a company to know whether they needed a change for improvement. Thus, complaint management brings a learning experience to organization in order to provide better service. Therefore, it is important to identify customer dissatisfaction through a systematic complaint handling or management. The study proposes a model of systematic complaint management which applied to academic library as a tool of service recovery. As such, the main purpose of this study is to investigate the critical success factors of complaint management towards service quality, customer satisfaction, customer loyalty and the impact to organizational image at academic library. Three academic libraries have been identified and selected for this project, the Library of Tun Sri Lanang, UKM, UTeM and UNIMAS. Using the justice theory, this study investigates the perception of customers on complaint management in terms of outcomes they receive, procedures used by organization and interpersonal treatment. In this study, there are five factors of complaint management identified, which includes speed of recovery, management system, empowerment, culture and psychology and tangible compensation. A questionnaire was designed and used as the data gathering instrument. A total of 600 respondents participated in this study. Ten hypotheses were used to test the relationships between complaint management, service quality, customer satisfaction, customer loyalty and organizational image. To measure the construct relationships, Structural Equation Model (SEM) approach was used. The results show that management system (b = 0.210; p < 0.05) exerts the highest positive impact on service quality. It followed by psychology and culture (b = 0.188; p < 0.05), empowerment (b = 0.179; p < 0.05) and tangible compensation (b = 0.175; p < 0.05). However, the empirical results suggest that speed of recovery (b = -0.009; p > 0.05) do not influence service quality. The second part of this study uses confirmatory factor analysis (CFA) to analyze and confirm the conceptual model proposed in this research. The result shows that all the values obtained in this study fits the data reasonably well.

Fermilab Library projects  

SciTech Connect

Preprint database management as done at various centers -- the subject of this workshop -- is hard to separate from the overall activities of the particular center. We therefore present the wider context at the Fermilab Library into which preprint database management fits. The day-to-day activities of the Library aside, the dominant activity at present is that of the ongoing Fermilab Library Automation. A less dominant but relatively time-consuming activity is that of doing more online searches in commercial databases on behalf of laboratory staff and visitors. A related activity is that of exploring the benefits of end-user searching of similar sources as opposed to library staff searching of the same. The Library Automation Project, which began about two years ago, is about to go fully online.'' The rationale behind this project is described in the documents developed during the December 1988--February 1989 planning phase.

Recent developments in imaging system assessment methodology, FROC analysis and the search model  

PubMed Central

A frequent problem in imaging is assessing whether a new imaging system is an improvement over an existing standard. Observer performance methods, in particular the receiver operating characteristic (ROC) paradigm, are widely used in this context. In ROC analysis lesion location information is not used and consequently scoring ambiguities can arise in tasks, such as nodule detection, involving finding localized lesions. This paper reviews progress in the free-response ROC (FROC) paradigm in which the observer marks and rates suspicious regions and the location information is used to determine whether lesions were correctly localized. Reviewed are FROC data analysis, a search-model for simulating FROC data, predictions of the model and a method for estimating the parameters. The search model parameters are physically meaningful quantities that can guide system optimization. PMID:21804679

Keynote Talk: Mining the Web 2.0 for Improved Image Search  

NASA Astrophysics Data System (ADS)

There are several semantic sources that can be found in the Web that are either explicit, e.g. Wikipedia, or implicit, e.g. derived from Web usage data. Most of them are related to user generated content (UGC) or what is called today the Web 2.0. In this talk we show how to use these sources of evidence in Flickr, such as tags, visual annotations or clicks, which represent the the wisdom of crowds behind UGC, to improve image search. These results are the work of the multimedia retrieval team at Yahoo! Research Barcelona and they are already being used in Yahoo! image search. This work is part of a larger effort to produce a virtuous data feedback circuit based on the right combination many different technologies to leverage the Web itself.

A method to search for strong galaxy-galaxy lenses in optical imaging surveys  

E-print Network

We present a semi-automated method to search for strong galaxy-galaxy lenses in optical imaging surveys. Our search technique constrains the shape of strongly lensed galaxies (or arcs) in a multi-parameter space, which includes the third order (octopole) moments of objects. This method is applied to the Deep Lens Survey (DLS), a deep ground based weak lensing survey imaging to $R\\sim26$. The parameter space of arcs in the DLS is simulated using real galaxies extracted from deep HST fields in order to more accurately reproduce the properties of arcs. Arcs are detected in the DLS using a pixel thresholding method and candidate arcs are selected within this multi-parameter space. Examples of strong galaxy-galaxy lens candidates discovered in the DLS F2 field (4 square degrees) are presented.

The Pore3D library package for the textural analysis of X-ray computed microtomographic images of rocks  

NASA Astrophysics Data System (ADS)

Many research fields in Geosciences require the knowledge of the three-dimensional (3D) texture of rocks. X-ray computed microtomography (?CT) supplies an effective method to directly acquire 3D information. Transmission X-ray ?CT is a non-destructive technique based on the mapping of the linear attenuation coefficient of X-rays crossing the investigated sample. The 3D distribution of constituents and the contrast based on the different absorption properties of the components can be enhanced by phase-contrast imaging. On an X-ray tomographic dataset, if spatial resolution at the micron scale and proper software are available, a complete textural and morphological quantitative analysis can be carried out and a number of parameters can be extracted, including geometry and organization of discrete rock components (such as crystals, vesicles, fractures, alteration-compositional zones). In the case of volcanic rocks, ?CT can be used to image and quantify the textural and morphological characteristics of the rock constituents, such as vesicles (gas bubbles in solidified, erupted products), crystals and glass fibers. For pyroclastic rocks, investigated parameters to characterize the vesicle portion are the size distribution, geometry and orientation of the pores, the pore-throat size and organization, the pore-surface roughness and the topology of the overall pore and pore-throat network. In this work we present several procedures able to extract quantitative information from ?CT images of volcanic rocks. The imaging experiments have been carried out at the Elettra Synchrotron Light Laboratory in Trieste (Italy) using both the synchrotron radiation at the SYRMEP beamline and a custom-developed ?CT system, named TOMOLAB, equipped with a microfocus X-ray tube and based on a cone-beam geometry. The reconstructed 3D images (or volumes) have been elaborated with a software library, named Pore3D, custom-developed by the SYRMEP group at Elettra. The Pore3D software library allows a quantitative description of the morphology and topology of the sample components and it operates directly in the 3D domain, without inferring about the 3D behavior from stacked 2D information. The library has been elaborated to merge together in a common environment some of the features already available in previous research and commercial software, customizing in some cases their applications, adding new tools for the artifact reduction in the tomographic images and enhancing state-of-the-art methods for the quantitative analysis, as based on the specific know-how acquired by the SYRMEP group. The microtomographic experiments on selected pumices and scoriae have given us the opportunity to reconstruct and study the 3D internal structure of very different samples, originated at volcanoes with unique eruptive behavior and hazard potential. In particular, the analysis of vesicle size, shape, distribution, orientation and degree of interconnectivity, quantifies aspects that are directly related to the magma nature and dynamics. In fact, magma near the Earth's surface exists as a multiphase system, including gas bubbles and solid crystals in a liquid medium. The rheology of the magma and the processes that govern the transition between effusive and explosive eruptions can be fully understood if the gas permeability and flow through the bubble networks are quantified. As pyroclasts are natural records of the magma state, in terms of texture and composition, during the last phases of the conduit ascent, the textural 3D information can be coupled to physical, rheological and chemical properties of the parent magma.

Visual-textual joint relevance learning for tag-based social image search.  

PubMed

Due to the popularity of social media websites, extensive research efforts have been dedicated to tag-based social image search. Both visual information and tags have been investigated in the research field. However, most existing methods use tags and visual characteristics either separately or sequentially in order to estimate the relevance of images. In this paper, we propose an approach that simultaneously utilizes both visual and textual information to estimate the relevance of user tagged images. The relevance estimation is determined with a hypergraph learning approach. In this method, a social image hypergraph is constructed, where vertices represent images and hyperedges represent visual or textual terms. Learning is achieved with use of a set of pseudo-positive images, where the weights of hyperedges are updated throughout the learning process. In this way, the impact of different tags and visual words can be automatically modulated. Comparative results of the experiments conducted on a dataset including 370+images are presented, which demonstrate the effectiveness of the proposed approach. PMID:22692911

A Direct Imaging Study to Search for and to Characterize Planetary Mass Companions  

NASA Astrophysics Data System (ADS)

We present preliminary results from two parallel programs to search for new substellar companions to nearby, young M-stars and to characterize the atmospheres of known planetary mass and temperature substellar companions. For the M-star survey, we are analyzing high angular resolution archival data on systems within 15pc, complementing a subset with well-determined young ages based on measurements of several age indicators. The results include stellar and substellar companion candidates, which we are currently pursuing with follow-up second epoch images. The characterization component of the project involves using LBT LMIRCam and MMT ARIES direct imaging and spectroscopy data to investigate the atmospheres of known young substellar companions with masses overlapping the planetary regime. These atmospheric studies will represent an analogous comparison to the atmospheres of young imaged planets, and provide a means to fundamentally test evolutionary models, enhancing our understanding of the overall substellar population.

[Determination of nine beta-agonist residues in pig tissues by liquid chromatography-tandem mass spectrometry combining with library search].  

PubMed

A new method has been developed using a hybrid triple-quadrupole linear ion trap (QTrap) mass spectrometer for the fast detection and identification of nine beta-agonists, clenbuterol, salbutamol, ractopamine, ritodrine, terbutaline, isoxsuprine, tulobuterol, cimaterol and bambuterol, in one single liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The homogenized tissue samples were purified with liquid-liquid extraction after enzymatic hydrolysis by P-glucuronidase/aryl sulfatase. After gradient elution separation on C(18) LC column using acetonitrile and formic acid aqueous solution as the mobile phases, a multiple reaction monitoring (MRM) scan as survey scan and an enhanced product ion (EPI) scan as dependent scan were performed in an information dependent acquisition (IDA) experiment. Finally, the identification of the drugs was carried out by library search with a newly developed MS/MS library based on EPI spectra at three different collision energies in positive mode. The analytical method in the present study was well validated and good results were obtained with respect to precision, repeatability and spiked recovery. The limits of detection of residues were 0.1 -0.2 micro g/kg for beta-agonists, and with a linear range from 0.1 to 50.0 micro g/L. Three concentration levels of 0. 5, 1. 0 and 5. 0 pg/kg were spiked in pig tissues, and the overall recoveries were between 72.0% and 95.1% with the relative standard deviations (RSDs) between 3. 1% and 12.1%. The real sample test showed that this method could be used for sensitive and accurate determination of beta-agonist residues in pig tissue PMID:23785990

Building an intranet digital mammography case library  

NASA Astrophysics Data System (ADS)

To practice mammography diagnosis effectively, radiologists expect convenient access to well-organized and authoritative mammography related information, especially when there is case in question. The purpose of this study is to build infrastructural diagnosis support by incorporating various clinical information into a digital mammography case library, and allow user to search the library based on mammographic findings. The digital mammography case library has a three- tier architecture: (1) Back-end mammography databases integrate multimedia clinical information from various operational systems, including RIS and PACS. Cases are stored in a finding index database powered by an object-relational database with finding-coded reports, which are modeled around the ACR BI-RADS (American College of Radiology, Breast Imaging Report and Data System) standard. (2) The middle-end application controllers process application logic, such as user authorization, HTTP request handling, database connection and dynamic HTML page generation. (3) Web-based user interface is developed for authorized Intranet personnel to formulate query based on radiological finding (such as mass, calcification and architectural distortion), shape and assessment, using ACR BI-RADS specified lexicon. The case library so far has 103 cases selected from over 800 digital mammography studies carried out at the Mt. Zion hospital, UCSF, during an on-going digital telemammography project. We believe that an Intranet based digital mammography case library with mammographic finding search capability facilitates continuous medical education and online decision support, by providing exemplary study to compare with case in question.

Metric performance in similar blocks search and their use in collaborative 3D filtering of grayscale images  

NASA Astrophysics Data System (ADS)

Similar blocks (patches) search plays an important role in image processing. However, there are many factors making this search problematic and leading to errors. Noise in images that arises due to bad acquisition conditions or other sources is one of the main factors. Performance of similar patch search might make worse dramatically if noise level is high and/or if noise is not additive, white and Gaussian. In this paper, we consider the influence of similarity metrics (distances) on search performance. We demonstrate that robustness of similarity metrics is a crucial issue for performance of similarity search. Two models of additive noise are used: AWGN and spatially correlated noise with a wide set of noise standard deviations. To investigate metric performance, five test images are used for artificially inserted group of identical blocks. Metric effectiveness evaluation is carried out for nine different metric (including several unconventional ones) in three domains (one spatial and two spectral). It is shown that conventional Euclidian metric might be not the best choice which depends upon noise properties and data processing domain. After establishing the best metrics, they are exploited within non-local image denoising, namely the BM3D filter. This filter is applied to intensity images of the database TID2008. It is demonstrated that the use of more robust metrics instead of classical ones (Euclidean) in BM3D filter allows improving similar block search and, as a result, provides better results of image denoising for the case of spatially correlated noise.

A High-Contrast Adaptive Optics Imaging Search for Giant Planets Around Young M Dwarfs  

NASA Astrophysics Data System (ADS)

Direct imaging planet searches are revealing the architecture of planetary systems at large separations (>10 AU) for the first time. Low-mass stars are generally being neglected from these surveys in part because of the dearth of known nearby young M dwarfs compared to young intermediate- and high-mass stars. As a result, there are few constraints on giant planet formation around low-mass stars at moderate (5-100 AU) separations. We present results from an ongoing high-contrast adaptive optics imaging survey of nearby (<30 pc) young (<300 Myr) M dwarfs with Keck-2/NIRC2 and Subaru/HiCIAO. Our survey is sensitive to planet masses of 6 MJup and 2 MJup at separations of 10 AU and 25 AU, respectively, for the median age (100 Myr) and distance (20 pc) of our sample. With a sample size of roughly 70 single M dwarfs, our survey represents the deepest and most extensive imaging search for planets around young low-mass stars to date.

Fully Polarimetric Passive W-band Millimeter Wave Imager for Wide Area Search  

SciTech Connect

We describe the design and phenomenology imaging results of a fully polarimetric W-band millimeter wave (MMW) radiometer developed by Pacific Northwest National Laboratory for wide-area search. Operating from 92 - 94 GHz, the W-band radiometer employs a Dicke switching heterodyne design isolating the horizontal and vertical mm-wave components with 40 dB of polarization isolation. Design results are presented for both infinite conjugate off-axis parabolic and finite conjugate off-axis elliptical fore-optics using optical ray tracing and diffraction calculations. The received linear polarizations are down-converted to a microwave frequency band and recombined in a phase-shifting network to produce all six orthogonal polarization states of light simultaneously, which are used to calculate the Stokes parameters for display and analysis. The resulting system performance produces a heterodyne receiver noise equivalent delta temperature (NEDT) of less than 150m Kelvin. The radiometer provides novel imaging capability by producing all four of the Stokes parameters of light, which are used to create imagery based on the polarization states associated with unique scattering geometries and their interaction with the down welling MMW energy. The polarization states can be exploited in such a way that man-made objects can be located and highlighted in a cluttered scene using methods such as image comparison, color encoding of Stokes parameters, multivariate image analysis, and image fusion with visible and infrared imagery. We also present initial results using a differential imaging approach used to highlight polarization features and reduce common-mode noise. Persistent monitoring of a scene using the polarimetric passive mm-wave technique shows great promise for anomaly detection caused by human activity.

Bodleian Library Broadside Ballads  

NSDL National Science Digital Library

There are few things as fine as a ballad, and the Bodleian Library at the University of Oxford happens to have over 30,000 in its collection. Broadside ballads were popular songs, and they were generally sold for a penny (or less) in villages around Britain between the sixteenth and twentieth centuries. Many of these ballads have been digitized and placed on this website for use by music historians, social historians, and members of the general public. Visitors can click on "The Project" to learn a bit more about this initiative, and they can move on to listen to a few sound files, and also learn about the graphic images used on such pieces of music. By that point, users will be very excited to browse through the digital collection on their own. If they click on the "Browse/Search" area, they can perform a detailed search on the ballad titles or first lines. To get started, visitors might want to type in words like "lucky" or "horse".

Optimal graph search based image segmentation for objects with complex topologies  

NASA Astrophysics Data System (ADS)

Segmenting objects with complicated topologies in 3D images is a challenging problem in medical image processing, especially for objects with multiple interrelated surfaces. In this paper, we extend a graph search based technique to simultaneously identifying multiple interrelated surfaces for objects that have complex topologies (e.g., with tree-like structures) in 3D. We first perform a pre-segmentation on the input image to obtain basic information of the objects' topologies. Based on the initial pre-segmentation, the original image is resampled along judiciously determined directions to produce a set of vectors of voxels (called voxel columns). The resampling process utilizes medial axes to ensure that voxel columns of appropriate lengths are used to capture the sought object surfaces. Then a geometric graph is constructed whose edges connect voxels in the resampled voxel columns and enforce the smoothness constraint and separation constraint on the sought surfaces. Validation of our algorithm was performed on the segmentation of airway trees and lung vascular trees in human in-vivo CT scans. Cost functions with directional information are applied to distinguish the airway inner wall and outer wall. We succeed in extracting the outer airway wall and optimizing the location of the inner wall in all cases, while the vascular trees are optimized as well. Comparing with the pre-segmentation results, our approach captures the wall surfaces more accurately, especially across bifurcations. The statistical evaluation on a double wall phantom derived from in-vivo CT images yields highly accurate results of the wall thickness measurement on the whole tree (with mean unsigned error 0.16 +/- 0.16mm).

Range-gated active-imaging system for search-and-rescue and surveillance operations  

NASA Astrophysics Data System (ADS)

Search and rescue (SAR) and general surveillance missions pose a number of challenges to imaging system. These systems must work often in low-light level, low-visibility conditions to find and identify targets. A new airborne payload has been developed to overcome several deficiencies encountered with conventional or low-light level cameras as well as thermal imaging sensors. The recent developments in laser diode arrays, laser diode beam collimation and gatable micro-channel plate intensifier have made it possible to build a compact active imaging system. This Airborne Laser Based Enhanced Detection and Observation System (ALBEDOS) is particularly efficient at night and in degraded weather conditions. ALBEDOS is based on a powerful laser diode array illuminator and a range-gated low-light-level TV camera. Therefore, it is immune to the blooming effect specific to highly sensitive cameras and eliminates most of the light backscatter caused by the presence of aerosols. It was proven to detect small retroreflective tapes over many kilometers. In October 1995, the system was installed on a Bell 412 helicopter and tested in various scenarios.

Automatic hip cartilage segmentation from 3D MR images using arc-weighted graph searching.  

PubMed

Accurate segmentation of hip joint cartilage from magnetic resonance (MR) images offers opportunities for quantitative investigations of pathoanatomical conditions such as osteoarthritis. In this paper, we present a fully automatic scheme for the segmentation of the individual femoral and acetabular cartilage plates in the human hip joint from high-resolution 3D MR images. The developed scheme uses an improved optimal multi-object multi-surface graph search framework with an arc-weighted graph representation that incorporates prior morphological knowledge as a basis for segmentation of the individual femoral and acetabular cartilage plates despite weak or incomplete boundary interfaces. This automated scheme was validated against manual segmentations from 3D true fast imaging with steady-state precession (TrueFISP) MR examinations of the right hip joints in 52 asymptomatic volunteers. Compared with expert manual segmentations of the combined, femoral and acetabular cartilage volumes, the automatic scheme obtained mean (± standard deviation) Dice's similarity coefficients of 0.81 (± 0.03), 0.79 (± 0.03) and 0.72 (± 0.05). The corresponding mean absolute volume difference errors were 8.44% (± 6.36), 9.44% (± 7.19) and 9.05% (± 8.02). The mean absolute differences between manual and automated measures of cartilage thickness for femoral and acetabular cartilage plates were 0.13?mm (± 0.12) and 0.11?mm (± 0.11), respectively.

Large Spectral Library Problem  

SciTech Connect

Hyperspectral imaging produces a spectrum or vector at each image pixel. These spectra can be used to identify materials present in the image. In some cases, spectral libraries representing atmospheric chemicals or ground materials are available. The challenge is to determine if any of the library chemicals or materials exist in the hyperspectral image. The number of spectra in these libraries can be very large, far exceeding the number of spectral channels collected in the ¯eld. Suppose an image pixel contains a mixture of p spectra from the library. Is it possible to uniquely identify these p spectra? We address this question in this paper and refer to it as the Large Spectral Library (LSL) problem. We show how to determine if unique identi¯cation is possible for any given library. We also show that if p is small compared to the number of spectral channels, it is very likely that unique identi¯cation is possible. We show that unique identi¯cation becomes less likely as p increases.

Imaging Search for Dynamically Inferred Planets in Nearby Debris Disk Systems  

NASA Astrophysics Data System (ADS)

The nearby stars Eps Eri, Vega, and Fomalhaut all host large debris disks with morphological structures that can be interpreted as being due to dynamical influence from unseen giant planets residing in the systems. At the ages of the systems of a few hundred Myrs, such planets are expected to have cooled down to temperatures of ~200 K, which makes them unreachable from the ground due to their faintness at JHKL wavelengths and the prohibitively large thermal background at longer wavelengths. Spitzer, however, has the sensitivity required at 4.5 micron to detect such objects. As we have shown previously (Janson et al. 2012), a dedicated observing strategy and data reduction scheme can be used to improve the Spitzer contrast performance by more than an order of magnitude compared to conventional methods, which enables this degree of sensitivity down to separations of ~10'. The corresponding detection space provides an excellent match to the predicted properties of inferred companions in the three systems. Here, we propose to re-observe Fomalhaut to follow up a candidate companion detected in our previous image, and to observe Vega and Eps Eri to search for their inferred companions. In each case we will be sensitive to Jovian or sub-Jovian companions in the primary separation regions of interest, which is a factor 3 better mass sensitivity than previously achieved. These observations provide a unique opportunity to study far colder and more Jupiter-like planets than previously imaged.

Direct imaging search for planetary companions next to young nearby stars  

E-print Network

We report first results from our ground-based infrared imaging search for sub-stellar companions (brown dwarfs and giant planets) of young (up to 100 Myrs) nearby (up to 75 pc) stars, where companions should be well separated from the central stars and still relatively bright due to ongoing accretion and/or contraction. Among our targets are all members of the TW Hya association, as well as other binary and single young stars either discovered recently among ROSAT sources (some of which as yet unpublished) or known before. Our observations are performed mainly with SOFI and SHARP at the ESO 3.5m NTT on La Silla and with ISAAC at the ESO 8.2m Antu (VLT-UT1) on Cerro Paranal, all in the H- and K-bands. We present direct imaging data and H-band spectroscopy of a faint object detected next to TWA-7 which, if at the same age and distance as the central star, could be an object with only a few Jupiter masses. Our spectrum shows, though, that it is a background K-dwarf.

A visual-search model observer for multislice-multiview SPECT images  

PubMed Central

Purpose: Mathematical model observers are intended for efficient assessment of diagnostic image quality, but model-observer studies often are not representative of clinical realities. Model observers based on a visual-search (VS) paradigm may allow for greater clinical relevance. The author has compared the performances of several VS model observers with those of human observers and an existing scanning model observer for a study involving nodule detection and localization in simulated Tc-99m single-photon emission computed tomography (SPECT) lung volumes. Methods: A localization receiver operating characteristic (LROC) study compared two iterative SPECT reconstruction strategies: an all-corrections (AllC) strategy with compensations for attenuation, scatter, and distance-dependent camera resolution and an “RC” strategy with resolution compensation only. Nodules in the simulation phantom were of three different relative contrasts. Observers in the study had access to the coronal, sagittal, and transverse displays of the reconstructed volumes. Three human observers each read 50 training volumes and 100 test volumes per reconstruction strategy. The same images were analyzed by a channelized nonprewhitening (CNPW) scanning observer and two VS observers. The VS observers implemented holistic search processes that identified focal points of Tc-99m uptake for subsequent analysis by the CNPW scanning model. The level of prior knowledge about the background structure in the images was a study variable for the model observers. Performance was scored by area under the LROC curve. Results: The average human-observer performances were respectively 0.67 ± 0.04 and 0.61 ± 0.03 for the RC and AllC strategies. Given approximate knowledge about the background structure, both VS models scored 0.69 ± 0.08 (RC) and 0.66 ± 0.08 (AllC). The scanning observer reversed the strategy ranking in scoring 0.73 ± 0.08 with the AllC strategy and 0.64 ± 0.08 with the RC strategy. The VS observers exhibited less sensitivity to variations in background knowledge compared to the scanning observer. Conclusions: The VS framework has the potential to increase the clinical similitude of model-observer studies and to enhance the ability of existing model observers to quantitatively predict human-observer performance.

Direct imaging search for planets around low-mass stars and spectroscopic characterization of young exoplanets  

NASA Astrophysics Data System (ADS)

Low--mass stars between 0.1--0.6 M? are the most abundant members our galaxy and may be the most common sites of planet formation, but little is known about the outer architecture of their planetary systems. We have carried out a high-contrast adaptive imaging search for gas giant planets between 1--13 MJup around 122 newly identified young M dwarfs in the solar neighborhood ( ? 35 pc). Half of our targets are younger than 145 Myr, and 90% are younger than 580 Myr. After removing 39 resolved stellar binaries, our homogeneous sample of 83 single young M dwarfs makes it the largest imaging search for planets around low--mass stars to date. Our H- and K- band coronagraphic observations with Subaru/HiCIAO and Keck/NIRC2 achieve typical contrasts of 9--13 mag and 12--14 mag at 100, respectively, which corresponds to limiting masses of ˜1--10 M Jup at 10--30 AU for most of our sample. We discovered four brown dwarfs with masses between 25--60 MJup at projected separations of 4--190 AU. Over 100 candidate planets were discovered, nearly all of which were found to be background stars from follow-up second epoch imaging. Our null detection of planets nevertheless provides strong statistical constraints on the occurrence rate of giant planets around M dwarfs. Assuming circular orbits and a logarithmically-flat power law distribution in planet mass and semi--major axis of the form d 2N=(dloga dlogm) infinity m0 a0, we measure an upper limit (at the 95% confidence level) of 8.8% and 12.6% for 1--13 MJup companions between 10--100 AU for hot start and cold start evolutionary models, respectively. For massive gas giant planets in the 5--13 M Jup range like those orbiting HR 8799, GJ 504, and beta Pictoris, we find that fewer than 5.3% (7.8%) of M dwarfs harbor these planets between 10--100 AU for a hot start (cold start) formation scenario. Our best constraints are for brown dwarf companions; the frequency of 13--75 MJup companions between (de--projected) physical separations of 10--100 AU is 2.1+2.1-1.2 %. Altogether, our results show that gas giant planets, especially massive ones, are rare in the outskirts of M dwarf planetary systems. If disk instability is a viable way to form planets, our constraints for the most common type of star imply that overall it is an inefficient mechanism.

Internet Library of Early Journals (ILEJ)  

NSDL National Science Digital Library

ILEJ is a joint project by the Universities of Birmingham, Leeds, Manchester and Oxford, conducted under the auspice of the eLib (Electronic Libraries) Programme (discussed in the Scout Report for September 20, 1996). The project has digitized selected twenty-year runs of three eighteenth- and three nineteenth-century journals and placed the images online at the site. Journals include: Annual Register (1758-78), Gentleman's Magazine (1731-50), Philosophical Transactions of the Royal Society (1757-77), Blackwood's Edinburgh Magazine (1843-52), Notes and Queries (1849-69), and The Builder (1843-9). Users can browse the journals by volume and section, conduct a standard search, or try a "fuzzy search" (limited availability). The project has considerable potential for scholars and students of British history and literature, although slow loading image pages may make it more useful as an online index to these journals.

Kohler Art Library: The Artists' Book Collection.  

NSDL National Science Digital Library

The Kohler Art Library at University of Wisconsin-Madison presents this illustrated database that indexes roughly 760 titles from its collection of over 800 artists' books. The database can be searched by book title, creator's name, publisher, date, or subjects. Other search terms relate to types of book structures, bindings, medium/technique, and contributors. Each record in the database has either a short description of the book's contents or a complete transcription of the colophon, the short paragraph traditionally placed at the end of a book, that tells about its production. In addition, for slightly more than half the books, several images are included. For example, the colophon for From a housewife's diary, by Claire Van Vliet, states that the "covering is dish towels bound by James Bicknell", and the image included shows that the towels are red plaid.

The Darlington Digital Library  

NSDL National Science Digital Library

The Darlington Digital Library was created from the first major collection of books, manuscripts, and maps donated to the University of Pittsburgh. The lion's share of the credit for this collection goes to the attorney William M. Darlington, who was born in Pittsburgh in 1815. During his long life, Darlington collected items like John James Audubon's "Birds of America" and hundreds of lithographs, broadsides, and other items. The collection eventually found its way to the university in 1925, and this collection contains over 3,000 items from its holdings. Visitors can scan through the major sections here via the Atlases, Books, Broadsides, and Images areas. The Atlases area includes five gems, including the Novus Orbis Regio, which features North and South America as Simon Gyrnaeus imagined them in 1532. The Broadsides area is a real treat, containing a proclamation by President George Washington declaring February 19, 1795 as a "Day of Public Thanksgiving and Prayer." Finally, users can use the search engine to look for items of particular interest. [KMG

Design and implementation of a real-time image registration in an infrared search and track system  

NASA Astrophysics Data System (ADS)

In order to realize the fast search and tracking of ground dim target under the movement condition of infrared detector, an infrared image registration method is proposed based on phase correlation registration and the feature point registration, which can make the infrared image motion compensation come true. After using the phase correlation registration for rough registration in movement infrared images, the high precision registration was realized by the priori information of the feature point image registration, which combined the features of phase correlation registration and feature point registration. Experimental results validate that the infrared image displacement information had been provided and the small detection rate and accuracy had been improved by the algorithm, which didn't reduce the registration accuracy in real-time IRST.

The 2MASS Wide-Field T Dwarf Search. IV Unting out T dwarfs with Methane Imaging  

E-print Network

We present first results from a major program of methane filter photometry for low-mass stars and brown dwarfs. The definition of a new methane filter photometric system is described. A recipe is provided for the differential calibration of methane imaging data using existing 2MASS photometry. We show that these filters are effective in discriminating T dwarfs from other types of stars, and demonstrate this with Anglo-Australian Telescope observations using the IRIS2 imager. Methane imaging data and proper motions are presented for ten T dwarfs identified as part of the 2MASS "Wide Field T Dwarf Search" -- seven of them initially identified as T dwarfs using methane imaging. We also present near-infrared moderate resolution spectra for five T dwarfs, newly discovered by this technique. Spectral types obtained from these spectra are compared to those derived from both our methane filter observations, and spectral types derived by other observers. Finally, we suggest a range of future programs to which these filters are clearly well suited: the winnowing of T dwarf and Y dwarf candidate objects coming from the next generation of near-infrared sky surveys; the robust detection of candidate planetary-mass brown dwarfs in clusters; the detection of T dwarf companions to known L and T dwarfs via deep methane imaging; and the search for rotationally-modulated time-variable surface features on cool brown dwarfs.

An integrated one-step system to extract, analyze and annotate all relevant information from image-based cell screening of chemical libraries.  

PubMed

Here we report the development and validation of a complete solution to manage and analyze the data produced by image-based phenotypic screening campaigns of small-molecule libraries. In one step initial crude images are analyzed for multiple cytological features, statistical analysis is performed and molecules that produce the desired phenotypic profile are identified. A naïve Bayes classifier, integrating chemical and phenotypic spaces, is built and utilized during the process to assess those images initially classified as "fuzzy"-an automated iterative feedback tuning. Simultaneously, all this information is directly annotated in a relational database containing the chemical data. This novel fully automated method was validated by conducting a re-analysis of results from a high-content screening campaign involving 33 992 molecules used to identify inhibitors of the PI3K/Akt signaling pathway. Ninety-two percent of confirmed hits identified by the conventional multistep analysis method were identified using this integrated one-step system as well as 40 new hits, 14.9% of the total, originally false negatives. Ninety-six percent of true negatives were properly recognized too. A web-based access to the database, with customizable data retrieval and visualization tools, facilitates the posterior analysis of annotated cytological features which allows identification of additional phenotypic profiles; thus, further analysis of original crude images is not required.

Enterprise Reference Library  

NASA Technical Reports Server (NTRS)

Introduction: Johnson Space Center (JSC) offers two extensive libraries that contain journals, research literature and electronic resources. Searching capabilities are available to those individuals residing onsite or through a librarian s search. Many individuals have rich collections of references, but no mechanisms to share reference libraries across researchers, projects, or directorates exist. Likewise, information regarding which references are provided to which individuals is not available, resulting in duplicate requests, redundant labor costs and associated copying fees. In addition, this tends to limit collaboration between colleagues and promotes the establishment of individual, unshared silos of information The Integrated Medical Model (IMM) team has utilized a centralized reference management tool during the development, test, and operational phases of this project. The Enterprise Reference Library project expands the capabilities developed for IMM to address the above issues and enhance collaboration across JSC. Method: After significant market analysis for a multi-user reference management tool, no available commercial tool was found to meet this need, so a software program was built around a commercial tool, Reference Manager 12 by The Thomson Corporation. A use case approach guided the requirements development phase. The premise of the design is that individuals use their own reference management software and export to SharePoint when their library is incorporated into the Enterprise Reference Library. This results in a searchable user-specific library application. An accompanying share folder will warehouse the electronic full-text articles, which allows the global user community to access full -text articles. Discussion: An enterprise reference library solution can provide a multidisciplinary collection of full text articles. This approach improves efficiency in obtaining and storing reference material while greatly reducing labor, purchasing and duplication costs. Most importantly, increasing collaboration across research groups provides unprecedented access to information relevant to NASA s mission. Conclusion: This project is an expansion and cost-effective leveraging of the existing JSC centralized library. Adding key word and author search capabilities and an alert function for notifications about new articles, based on users profiles, represent examples of future enhancements.

Robust coastal region detection method using image segmentation and sensor LOS information for infrared search and track  

NASA Astrophysics Data System (ADS)

This paper presents a novel coastal region detection method for infrared search and track. The coastal region detection is critical to home land security and ship defense. Detected coastal region information can be used to the design of target detector such as moving target detection and threshold setting. We can detect coastal regions robustly by combining the infrared image segmentation and sensor line-of-sight (LOS) information. The K-means-based image segmentation can provide initial region information and the sensor LOS information can predict the approximate horizon location in images. The evidence of coastal region is confirmed by contour extraction results. The experimental results on remote coasts and near coasts validate the robustness of the proposed coastal region detector.

Ontology-guided organ detection to retrieve web images of disease manifestation: towards the construction of a consumer-based health image library  

PubMed Central

Background Visual information is a crucial aspect of medical knowledge. Building a comprehensive medical image base, in the spirit of the Unified Medical Language System (UMLS), would greatly benefit patient education and self-care. However, collection and annotation of such a large-scale image base is challenging. Objective To combine visual object detection techniques with medical ontology to automatically mine web photos and retrieve a large number of disease manifestation images with minimal manual labeling effort. Methods As a proof of concept, we first learnt five organ detectors on three detection scales for eyes, ears, lips, hands, and feet. Given a disease, we used information from the UMLS to select affected body parts, ran the pretrained organ detectors on web images, and combined the detection outputs to retrieve disease images. Results Compared with a supervised image retrieval approach that requires training images for every disease, our ontology-guided approach exploits shared visual information of body parts across diseases. In retrieving 2220 web images of 32 diseases, we reduced manual labeling effort to 15.6% while improving the average precision by 3.9% from 77.7% to 81.6%. For 40.6% of the diseases, we improved the precision by 10%. Conclusions The results confirm the concept that the web is a feasible source for automatic disease image retrieval for health image database construction. Our approach requires a small amount of manual effort to collect complex disease images, and to annotate them by standard medical ontology terms. PMID:23792805

Single-Molecule Imaging of DNA Pairing by RecA Reveals a 3-Dimensional Homology Search  

PubMed Central

DNA breaks can be repaired with high-fidelity by homologous recombination. A ubiquitous protein that is essential for this DNA template-directed repair is RecA1. After resection of broken DNA to produce single-stranded DNA (ssDNA), RecA assembles on this ssDNA into a filament with the unique capacity to search and find DNA sequences in double-stranded DNA (dsDNA) that are homologous to the ssDNA. This homology search is vital to recombinational DNA repair, and results in homologous pairing and exchange of DNA strands. Homologous pairing involves DNA sequence-specific target location by the RecA-ssDNA complex. Despite decades of study, the mechanism of this enigmatic search process remains unknown. RecA is a DNA-dependent ATPase, but ATP hydrolysis is not required for DNA pairing and strand exchange2,3, eliminating active search processes. Using dual optical trapping to manipulate DNA, and single-molecule fluorescence microscopy to image DNA pairing, we demonstrate that both the three-dimensional conformational state of the dsDNA target and the length of the homologous RecA-ssDNA filament play important roles in the homology search. We discovered that as the end-to-end distance of the target dsDNA molecule is increased, constraining its available 3-dimensional conformations, the rate of homologous pairing decreases. Conversely, when the length of the ssDNA in the nucleoprotein filament is increased, homology is found faster. We propose a model for the DNA homology search process termed “intersegmental contact sampling”, wherein the intrinsic multivalent nature of the RecA nucleoprotein filament is employed to search DNA sequence space within 3-dimensional domains of DNA, exploiting multiple weak contacts to rapidly search for homology. Our findings highlight the importance of the 3-dimensional conformational dynamics of DNA, reveal a previously unknown facet of the homology search, and provide insight into the mechanism of DNA target location by this member of a universal family of proteins.

Los Angeles Public Library: Electronic Neighborhood  

NSDL National Science Digital Library

Many urban public library systems across the United States have accumulated large troves of paper ephemera over the years, and the Los Angeles Public Library system is no exception. Funded by a grant from the California State Library, the Fletcher Jones Foundation, and the John Randolph Haynes and Dora Haynes Foundation, the Electronic Neighborhood allows the internet-browsing public access to a number of these documents. The database located here includes a large collection of photographs documenting the city's development, a collection of restaurant menus, and an index to fiction works that take place in and around California. The photo database contains over 2.5 million archival records, and a number of thematic online photo exhibits, including ones that document the 1932 Los Angeles Olympics and golf in Hollywood. The menu database is particularly fascinating, as users can search for a number of restaurant menus from the past century. While not all of the records include scanned menu images, a number of them are already available, such as those from the now-defunct Brown Derby.

Mapping of low-frequency chimeric yeast artificial chromosome libraries from human chromosomes 16 and 21 by fluorescence in situ hybridization and quantitative image analysis  

SciTech Connect

Yeast artificial chromosome (YAC) clones from low-frequency chimeric libraries of human chromosomes 16 and 21 were mapped onto human diploid fibroblast metaphase chromosomes using fluorescence in situ hybridization (FISH) and digital imaging microscopy. YACs mapped onto chromosome 21 were selected to provide subregional location and ordering of known and unknown markers on the long arm of chromosome 21, particularly in the Down syndrome region (q22). YACs mapped onto chromosome 16 were selected to overlap regions spanning chromosome 16 cosmid maps. YAC clones were indirectly labeled with fluorescein, and the total DNA of the chromosome was counterstained with propidium iodide. A single image containing both the FISH signal and the whole chromosome was acquired for each chromosome of interest containing the fluorescent probe signal in a metaphase spread. From the digitized image, the fluorescence intensity profile through the long axis of the chromosome gave the total chromosome length and the probe position. The map position of the probe was expressed as the fractional length (FL) of the total chromosome relative to the end of the short arm (Flpter). From each clone hybridized, 20-40 chromosome images were analyzed. Thirty-eight YACs were mapped onto chromosome 16, and their FLs were distributed along the short and long arms. On chromosome 21, 47 YACs were mapped, including 12 containing known markers. To confirm the order of a dense population of YACs within the Down syndrome region, a two-color mapping strategy was used in which an anonymous YAC was located relative to one or two known markers on the metaphase chromosome. The chromosome FL maps have a 1- to 2-Mb resolution, and the FL measurement of each probe has a typical standard error of 0.5-1 Mb. 14 refs., 3 figs., 3 tabs.

Detection and confirmation of 60 anabolic and androgenic steroids in equine plasma by liquid chromatography-tandem mass spectrometry with instant library searching.  

PubMed

In 2008, Pennsylvania (PA) became the first State in the USA to ban and enforce the ban on the use of anabolic and androgenic steroids (AAS) in equine athletes by using plasma for analysis. To enforce the ban, a rapid and high-throughput method for analysis of 60 AAS in equine plasma was developed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Analytes were recovered from plasma by liquid-liquid extraction (LLE) using methyl tert-butyl ether, separated on a reversed-phase C?? column and analyzed by electrospray ionization mass spectrometry. Multiple-reaction monitoring (MRM) scan was employed for screening. When the MRM signal of an analyte exceeded 1000 counts per second (cps), information-dependent acquisition (IDA) triggered generation of an enhanced product ion (EPI) scan of the analyte. A library for the analytes was simultaneously established using the EPI spectrum. Unambiguous identification of any of the 60 AAS in a test sample was based on both the presence of MRM response within the correct retention time (t(R)) window and a qualitative match between EPI spectrum of the test sample and that of the reference drug standard stored in the library. Total analysis time was 7 min. The limit of detection (LOD) and limit of confirmation (LOC) for most of the analytes were 0.01-2 ng/mL and 0.1-10 ng/mL, respectively. Recovery of the analytes from plasma by LLE was 74-138%. The method was successfully verified and is routinely used in the screening of post-race equine plasma samples for the presence of these 60 AAS. The method is rapid, sensitive, reproducible, and reliable. PMID:20878876

High Content Image-Based Screening of a Protease Inhibitor Library Reveals Compounds Broadly Active against Rift Valley Fever Virus and Other Highly Pathogenic RNA Viruses  

PubMed Central

High content image-based screening was developed as an approach to test a protease inhibitor small molecule library for antiviral activity against Rift Valley fever virus (RVFV) and to determine their mechanism of action. RVFV is the causative agent of severe disease of humans and animals throughout Africa and the Arabian Peninsula. Of the 849 compounds screened, 34 compounds exhibited ?50% inhibition against RVFV. All of the hit compounds could be classified into 4 distinct groups based on their unique chemical backbone. Some of the compounds also showed broad antiviral activity against several highly pathogenic RNA viruses including Ebola, Marburg, Venezuela equine encephalitis, and Lassa viruses. Four hit compounds (C795-0925, D011-2120, F694-1532 and G202-0362), which were most active against RVFV and showed broad-spectrum antiviral activity, were selected for further evaluation for their cytotoxicity, dose response profile, and mode of action using classical virological methods and high-content imaging analysis. Time-of-addition assays in RVFV infections suggested that D011-2120 and G202-0362 targeted virus egress, while C795-0925 and F694-1532 inhibited virus replication. We showed that D011-2120 exhibited its antiviral effects by blocking microtubule polymerization, thereby disrupting the Golgi complex and inhibiting viral trafficking to the plasma membrane during virus egress. While G202-0362 also affected virus egress, it appears to do so by a different mechanism, namely by blocking virus budding from the trans Golgi. F694-1532 inhibited viral replication, but also appeared to inhibit overall cellular gene expression. However, G202-0362 and C795-0925 did not alter any of the morphological features that we examined and thus may prove to be good candidates for antiviral drug development. Overall this work demonstrates that high-content image analysis can be used to screen chemical libraries for new antivirals and to determine their mechanism of action and any possible deleterious effects on host cellular biology.

Cuneiform Digital Library Initiative  

NSDL National Science Digital Library

The Cuneiform Digital Library Initiative (CDLI) is an international group of Assyriologists, museum curators and historians making available cuneiform tablets dating from the beginning of writing, ca. 3200 B.C., until the end of the third millennium. Led by a team at the University of California at Los Angeles, with initial National Science Foundation funding, this ambitious project seeks expose the collections within the US, Germany, Austria, and the Czech Republic, to a broad audience of specialists, scholars and advanced students. The presently limited (but growing) data set consists of text and image (current library entries offer high quality images), combining document transliterations, text glossaries and digitized originals and photo archives of early cuneiform. To promote discussion and scholarship, CDLI established two, English language, electronic journals which are currently accepting submissions, Cuneiform Digital Library Bulletin (for the rapid distribution of short notes) and the Cuneiform Digital Library Journal (more substantive scholarly contributions). The initial contributions will be made available in March 2002. This collection can be somewhat difficult to navigate, but offers a great opportunity to interested scholars and students.

Search for cool giant exoplanets around young and nearby stars - VLT/NaCo near-infrared phase-coronagraphic and differential imaging  

E-print Network

[Abridged] Context. Spectral differential imaging (SDI) is part of the observing strategy of current and future high-contrast imaging instruments. It aims to reduce the stellar speckles preventing the detection of cool planets, using in/out methane-band images. It attenuates the signature of off-axis companions to the star, like angular differential imaging (ADI). However, this attenuation is dependent on the spectral properties of the low-mass companions we are searching for. The implications of this particularity on the estimation of the detection limits have been poorly explored so far. Aims. We perform an imaging survey to search for cool (Teff2. According to the BT-Settl model, this translates into Tefffilter characteristics and better image quality.

Segmentation of knee joints in x-ray images using decomposition-based sweeping and graph search  

NASA Astrophysics Data System (ADS)

Plain radiography (i.e., X-ray imaging) provides an effective and economical imaging modality for diagnosing knee illnesses and injuries. Automatically segmenting and analyzing knee radiographs is a challenging problem. In this paper, we present a new approach for accurately segmenting the knee joint in X-ray images. We first use the Gaussian high-pass filter to remove homogeneous regions which are unlikely to appear on bone contours. We then presegment the bones and develop a novel decomposition-based sweeping algorithm for extracting bone contour topology from the filtered skeletonized images. Our sweeping algorithm decomposes the bone structures into several relatively simple components and deals with each component separately based on its geometric characteristics using a sweeping strategy. Utilizing the presegmentation, we construct a graph to model the bone topology and apply an optimal graph search algorithm to optimize the segmentation results (with respect to our cost function defined on the bone boundaries). Our segmented results match well with the manual tracing results by radiologists. Our segmentation approach can be a valuable tool for assisting radiologists and X-ray technologists in clinical practice and training.

Searching for Linear Dependencies between Heart Magnetic Resonance Images and Lipid Profiles  

NASA Astrophysics Data System (ADS)

Information derived from "omics" data in life science research are frequently limited by specific spatial or temporal scales these data describe. As a case study of integrating physiological and molecular data in human, here we study associations between the heart magnetic resonance images and serum lipidomic profiles. In the best case, such associations could help infer the physiologic state of the heart from a blood serum sample without need to use expensive imaging techniques. Strong marginal and partial correlations are found between the lipid profiles and parameters derived from the heart images. Regression analyses are applied to study these dependencies in more detail. This study demonstrates the feasibility of mapping lipid profiles to heart images, and thus combining information from two very different scales, small molecules and macroscopic physiologic features. Such mappings could be generalized to other "omics" data as well to complete our picture of the holistic function of a living organism.

Computational wave optics library for C++: CWO++ library  

E-print Network

Diffraction calculations, such as the angular spectrum method, and Fresnel diffractions, are used for calculating scalar light propagation. The calculations are used in wide-ranging optics fields: for example, computer generated holograms (CGHs), digital holography, diffractive optical elements, microscopy, image encryption and decryption, three-dimensional analysis for optical devices and so on. However, increasing demands made by large-scale diffraction calculations have rendered the computational power of recent computers insufficient. We have already developed a numerical library for diffraction calculations using a graphic processing unit (GPU), which was named the GWO library. However, this GWO library is not user-friendly, since it is based on C language and was also run only on a GPU. In this paper, we develop a new C++ class library for diffraction and CGH calculations, which is referred as to a CWO++ library, running on a CPU and GPU. We also describe the structure, performance, and usage examples o...

SciTech Connect

This report describes research and development efforts toward a novel passive millimeter-wave (mm-wave) electromagnetic imaging device for broad-area search. It addresses the technical challenge of detecting anomalies that occupy a small fraction of a pixel. The purpose of the imager is to pinpoint suspicious locations for cuing subsequent higher-resolution imaging. The technical basis for the approach is to exploit thermal and polarization anomalies that distinguish man-made features from natural features.

Evaluation of Diffusion-Tensor Imaging-Based Global Search and Tractography for Tumor Surgery Close to the Language System  

PubMed Central

Pre-operative planning and intra-operative guidance in neurosurgery require detailed information about the location of functional areas and their anatomo-functional connectivity. In particular, regarding the language system, post-operative deficits such as aphasia can be avoided. By combining functional magnetic resonance imaging and diffusion tensor imaging, the connectivity between functional areas can be reconstructed by tractography techniques that need to cope with limitations such as limited resolution and low anisotropic diffusion close to functional areas. Tumors pose particular challenges because of edema, displacement effects on brain tissue and infiltration of white matter. Under these conditions, standard fiber tracking methods reconstruct pathways of insufficient quality. Therefore, robust global or probabilistic approaches are required. In this study, two commonly used standard fiber tracking algorithms, streamline propagation and tensor deflection, were compared with a previously published global search, Gibbs tracking and a connection-oriented probabilistic tractography approach. All methods were applied to reconstruct neuronal pathways of the language system of patients undergoing brain tumor surgery, and control subjects. Connections between Broca and Wernicke areas via the arcuate fasciculus (AF) and the inferior fronto-occipital fasciculus (IFOF) were validated by a clinical expert to ensure anatomical feasibility, and compared using distance- and diffusion-based similarity metrics to evaluate their agreement on pathway locations. For both patients and controls, a strong agreement between all methods was observed regarding the location of the AF. In case of the IFOF however, standard fiber tracking and Gibbs tracking predominantly identified the inferior longitudinal fasciculus that plays a secondary role in semantic language processing. In contrast, global search resolved connections in almost every case via the IFOF which could be confirmed by probabilistic fiber tracking. The results show that regarding the language system, our global search is superior to clinically applied conventional fiber tracking strategies with results similar to time-consuming global or probabilistic approaches.

A comparative study of correspondence-search algorithms in MIS images.  

PubMed

The ability to find image similarities (feature matching) between laparoscopic views is essential in many robotic-assisted Minimally-Invasive Surgery (MIS) applications. Differently from feature tracking methods, feature matching does not make any restrictive assumption about the sequential nature of the two images or about the organ motion, and could then be used, e.g., to recover tracked features that were lost due to a prolonged occlusion, a sudden endoscopic-camera retraction, or a strong illumination change. This paper provides researchers in the medical-imaging computing community with an extensive comparison of the most up-to-date feature-matching algorithms over a large (and annotated) data set of 100 MIS-image pairs obtained from real interventions. The accuracy of these methods, as well as their ability to consistently retrieve as many good matches as possible, are evaluated for popular feature detectors. In addition, the dataset and the software implementations of these methods are made freely available on the Internet. PMID:23286101

Advanced image collection, information extraction, and change detection in support of NN-20 broad area search and analysis  

SciTech Connect

This report describes the work performed at the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy`s Office of Nonproliferation and National Security, Office of Research and Development (NN-20). The work supports the NN-20 Broad Area Search and Analysis, a program initiated by NN-20 to improve the detection and classification of undeclared weapons facilities. Ongoing PNNL research activities are described in three main components: image collection, information processing, and change analysis. The Multispectral Airborne Imaging System, which was developed to collect georeferenced imagery in the visible through infrared regions of the spectrum, and flown on a light aircraft platform, will supply current land use conditions. The image information extraction software (dynamic clustering and end-member extraction) uses imagery, like the multispectral data collected by the PNNL multispectral system, to efficiently generate landcover information. The advanced change detection uses a priori (benchmark) information, current landcover conditions, and user-supplied rules to rank suspect areas by probable risk of undeclared facilities or proliferation activities. These components, both separately and combined, provide important tools for improving the detection of undeclared facilities.

Ground-based exoplanet near-infrared search by imaging and spectroscopy: 3 new companion candidates in TWA  

E-print Network

We report first results from our ground-based infrared imaging search for sub-stellar companions (brown dwarfs and giant planets) of young (up to 100 Myrs) nearby (up to 100 pc) stars, where companions should be well separated from the central stars and still relatively bright due to ongoing accretion and/or contraction. Our observations are performed mainly with SOFI and SHARP at the ESO 3.5m NTT on La Silla (imaging) and with ISAAC at the ESO 8.2m Antu (VLT-UT1) on Cerro Paranal (imaging and spectroscopy), all in the H- and K-bands. Here, we present new companion candidates around three T Tauri stars (TWA-8 A, RXJ1121.1-3845, and RXJ1121.3-3447 N) in the TW Hya group, which would have been sub-stellar if at the same distance and age as the T Tauri stars, but are found to be background stars by spectroscopy.

Recent health sciences library building projects.  

PubMed Central

The Medical Library Association's third annual survey of recent health sciences library building projects identified fourteen libraries planning, expanding, or constructing new library facilities. Three of five new library buildings are freestanding structures where the library occupies all or a major portion of the space. The two other new facilities are for separately administered units where the library is a major tenant. Nine projects involve additions to or renovations of existing space. Six projects are in projected, predesign, or design stages or are awaiting funding approval. This paper describes four projects that illustrate technology's growing effect on librarians and libraries. They are designed to accommodate change, a plethora of electronic gear, and easy use of technology. Outwardly, they do not look much different than many other modern buildings. But, inside, the changes have been dramatic although they have evolved slowly as the building structure has been adapted to new conditions. Images PMID:8251970

Images Canada  

NSDL National Science Digital Library

Borrowing a good idea from PictureAustralia (last mentioned in the December 1, 2000 Scout Report), Images Canada provides a central point to start a cross-collection search through more than 75,000 images held by participating Canadian museums, archives, and libraries. Like PictureAustralia, there are three ways to search: by keyword (simply enter terms in a box), advanced (limit terms to specific fields), and Trails, ("pre-selected searches on a particular topic or theme"). Currently, the main trails are The Great Canadian Outdoors -- the path to fishing, hunting, and wild life -- and From Sea to Sea to Sea -- exploring Canada's geography by plane, train, and automobile. There are also several photo essays written by archivists and curators, highlighting collection items on subjects such as J.B. Tyrrell (1858-1957), an explorer, geologist, mining consultant and historian; and "Celebrating Dominion Day 1867-1917" (now known as Canada Day).

Military Education and Research Library Network  

NSDL National Science Digital Library

The official Web presence of the military education libraries in the United States and Europe, MERLN links together the holdings and electronic information resources of fourteen libraries, collectively the "largest and most comprehensive collections of military information resources in the world." Users can select a Topic Area (or create a custom topic) or a specific catalog, and then search by title, author, subject heading, or advanced options. The databases are also browseable by author, title, subject, or year. A sample search under title keyword for all libraries for "carpet bombing" produced 74 hits, while "Antietam" produced 266. Hits for each library are listed in a frame on the left-hand side, while basic bibliographic information on each title is listed on the right, with links to more detailed information. Users can repeat previous searches and combine them with other searches using the History option and also save and email selected search returns. Please note that at present the library catalogs for the Marine Corps University Research Center, the Marshall Center, the US Coast Guard Academy, and the US Naval Academy cannot be directly searched from MERLN, but efforts are underway to correct the problem. Users can access the homepages of these libraries, and all of the others linked through MERLN, from the main page.

Report on the search for atmospheric holes using airs image data  

NASA Technical Reports Server (NTRS)

Frank et al (1986) presented a very controversial hypothesis which states that the Earth is being bombarded by water-vapor clouds resulting from the disruption and vaporization of small comets. This hypothesis was based on single-pixel intensity decreases in the images of the earth's dayglow emissions at vacuum-ultraviolet (VUV) wavelengths using the DE-1 imager. These dark spots, or atmospheric holes, are hypothesized to be the result of VUV absorption by a water-vapor cloud between the imager and the dayglow-emitting region. Examined here is the VUV data set from the Auroral Ionospheric Remote Sensor (AIRS) instrument that was flown on the Polar BEAR satellite. AIRS was uniquely situated to test this hypothesis. Due to the altitude of the sensor, the holes should show multi-pixel intensity decreases in a scan line. A statistical estimate indicated that sufficient 130.4-nm data from AIRS existed to detect eight to nine such holes, but none was detected. The probability of this occurring is less than 1.0 x 10(exp -4). A statistical estimate indicated that sufficient 135.6-nm data from AIRS existed to detect approx. 2 holes, and two ambiguous cases are shown. In spite of the two ambiguous cases, the 135.6-nm data did not show clear support for the small-comet hypothesis. The 130.4-nm data clearly do not support the small-comet hypothesis.

We present high-speed photometry (resolution 0.1 s) obtained during the commissioning of the Berkely Visible Imaging Tube system on the Southern African Large Telescope (SALT). The observations were an attempt to search for very rapid p-mode oscillations in white dwarf stars and included three DA stars known to be g-mode pulsators (ZZ Cet, HK Cet and AF Pic), one other DA star (WD 1056-384) not known to be variable and one AM Cvn star (HP Lib). No evidence was found for any variations greater than about 1 mmag in amplitude (˜0.1 per cent) at frequencies in excess of 60 mHz (periods <17 s) in any of the target stars, though several previously known g-mode frequencies were recovered.

Afghanistan Digital Library  

NSDL National Science Digital Library

The goal of the Afghanistan Digital Library at New York University is "to retrieve and restore the first sixty years of Afghanistan's published cultural heritage." This period, from 1871 to 1930, is of great importance as the earliest publications from this time frame are very rare and decades of war have not helped the situation. A team of scholars working at the National Archives in Kabul and NYU has helped to digitize a number of these documents for inclusion in this digital library. The project is sponsored by NYU Libraries, the National Endowment for the Humanities, and The Reed Foundation. Currently, the archive contains over 380 books, and visitors can browse them at their leisure. There is a search feature, but as the transliteration part of the project is still in development, visitors might just want to look around at items they find compelling. The viewer application is quite user-friendly, and visitors can zoom in to examine various details of each work.

Collection Metadata Solutions for Digital Library Applications  

NASA Technical Reports Server (NTRS)

Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemas that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadata "registers" the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system.

A NICMOS Direct Imaging Search for Giant Planets around the Single White Dwarfs in the Hyades  

E-print Network

We report preliminary results from our search for massive giant planets (6-12 Jupiter masses) around the known seven single white dwarfs in the Hyades cluster at sub-arcsec separations. At an age of 625 Myr, the white dwarfs had progenitor masses of about 3 solar masses, and massive gaseous giant planets should have formed in the massive circumstellar disks around these ex-Herbig A0 stars, probably at orbital separations similar or slightly larger than that of Jupiter. Such planets would have survived the post-Main-Sequence mass loss of the parent star and would have migrated outward adiabatically to a distance of about 25 AU. At the distance of the Hyades (45 pc) this corresponds to an angular separation of 0.5 arcsec. J and H magnitudes of these giants are in the range of 20.5-23.3 mag, which can be resolved with NICMOS. The achieved sensitivities and contrast ratios agree well with simulations. Preliminary evaluation of the NICMOS data set did not reveal any evidence for neither planetary mass companions with masses down to about 10 Jupiter masses nor brown dwarfs around any of the seven white dwarfs for separations larger than 0.5 arcsec.

Infrared search and track and imaging system: testing in the laboratory and during flight  

NASA Astrophysics Data System (ADS)

The PIRATE, short for Passive Infra Red Airborne Tracking Equipment, multi mode Infrared Sensor, has been developed and manufactured by the Eurofirst consortium for the Eurofighter 2000 Aircraft. The consortium is led by SELEX Galileo, contract award, from Italy, and includes THALES UK, and TECNOBIT from Spain. Testing of the unit has been performed either in the laboratory and in flight. In the laboratory, sophisticated measurement techniques to verify optical parameters like the MTF, the NETD and the MRTD in the different Field of View have been employed, as well as for the detection, tracking and identification functions. On top of that, a flight test campaign has started to verify the performance, when operating in real scenarios, with cooperative and opportunity targets, across different weather conditions, like clean sky, but also misty and cloudy weather, haze and hail, generally not ideal to the infrared wavelength operation, either during tracking or imaging.

A search for spectral units on the Uranian satellites using color ratio images  

NASA Technical Reports Server (NTRS)

Twenty multispectral sets of calibrated coregistered Voyager 2 images of the Uranian satellites are analyzed in order to identify spectrally distinct surface units and associate these units with specific endogenic or exogenic surface processes. Several regions on each satellite where significant spectral/compositional diversity could be expected were identified by morphologic unit mapping. All the Uranian satellites were found to exhibit some degree of spectral variability associated with bright impact craters, with the typical trend being that the bright craters and their associated ejecta deposits are less red than the remainder of the satellites by 5 to 30 percent. Oberon shows the greatest variability, followed by Titania and Ariel. Morphologic features on Miranda and Ariel possibly associated with endogenic processes such as tectonism or ice volcanism do not exhibit as high a degree of spectral variability relative to their surroundings as bright impact craters.

Searching early bone metastasis on plain radiography by using digital imaging processing  

SciTech Connect

Some authors mention that it is not possible to detect early bone metastasis on plain radiography. In this work we use digital imaging processing to analyze three radiographs taken from a patient with bone metastasis discomfort on the right shoulder. The time period among the first and second radiography was approximately one month and between the first and the third one year. This procedure is a first approach in order to know if in this particular case it was possible to detect an early bone metastasis. The obtained results suggest that by carrying out a digital processing is possible to detect the metastasis since the radiography contains the information although visually it is not possible to observe it.

PIERCING THE GLARE: A DIRECT IMAGING SEARCH FOR PLANETS IN THE SIRIUS SYSTEM  

SciTech Connect

Astrometric monitoring of the Sirius binary system over the past century has yielded several predictions for an unseen third system component, the most recent one suggesting a {approx}<50 M{sub Jup} object in a {approx}6.3 year orbit around Sirius A. Here we present two epochs of high-contrast imaging observations performed with Subaru IRCS and AO188 in the 4.05 {mu}m narrowband Br {alpha} filter. These data surpass previous observations by an order of magnitude in detectable companion mass, allowing us to probe the relevant separation range down to the planetary-mass regime (6-12 M{sub Jup} at 1'', 2-4 M{sub Jup} at 2'', and 1.6 M{sub Jup} beyond 4''). We complement these data with one epoch of M-band observations from MMT/AO Clio, which reach comparable performance. No data set reveals any companion candidates above the 5{sigma} level, allowing us to refute the existence of Sirius C as suggested by the previous astrometric analysis. Furthermore, our Br {alpha} photometry of Sirius B confirms the lack of an infrared excess beyond the white dwarf's blackbody spectrum.

[Searching for psychosocial endophenotypes in schizophrenia: the innovative role of brain imaging].  

PubMed

Schizophrenia is a disease with heterogeneous features and often a disabling longitudinal outcome. In order to achieve a better understanding of the disease, a detailed characterization and definition of symptomatology, social functioning and cognitive performance of patients is required. Imaging techniques may allow to identify measurable markers of different subgroups of patients, who share common clinical course and, probably, a similar hereditary pathway. The review offers a description of cross-sectional, predictive and longitudinal studies on the relationship between biological, clinical and psychosocial features of patients with schizophrenia. Patients with a more severe and disabling course of illness present larger ventricles, smaller prefrontal, temporal and occipital cortices and smaller subcortical regions such as basal ganglia, the thalamus and limbic areas. These alterations are predictive of a worse prognosis, as observed in predictive and longitudinal studies, both on chronic and first episode patients. The detection of more homogenous groups of patients with schizophrenia will help neurobiological research progress in this field. Furthermore, patients with similar clinical and biological features could undergo more tailored therapeutic and rehabilitative strategies. PMID:22622244

Historical Postcards of New York City from the Picture Collection at Mid-Manhattan Library  

NSDL National Science Digital Library

From Van Cortland Park in the Bronx down to the bucolic stylings of Staten Island in the late 19th century, this very fun online exhibition from the New York Public Library will sate the desires of those persons with a penchant for historical postcards. Recently, the Library placed five hundred postcards depicting views of all five boroughs in the late 19th and early 20th century within the much larger NYPL Digital Gallery. This exhibition offers a brief introduction to these depictions of New York's past, and visitors can get a taste of the images by looking through sections that include "A Record of Time", "A Record of Place", and "A Record of the People". Visitors can look at promenades in Central Park, the early days of Riverside Drive, and the Astor Library. After that, they can perform their own postcard searches, and purists will note that the back of every postcard has also been scanned for this project.

Features extraction of flotation froth images and BP neural network soft-sensor model of concentrate grade optimized by shuffled cuckoo searching algorithm.  

PubMed

For meeting the forecasting target of key technology indicators in the flotation process, a BP neural network soft-sensor model based on features extraction of flotation froth images and optimized by shuffled cuckoo search algorithm is proposed. Based on the digital image processing technique, the color features in HSI color space, the visual features based on the gray level cooccurrence matrix, and the shape characteristics based on the geometric theory of flotation froth images are extracted, respectively, as the input variables of the proposed soft-sensor model. Then the isometric mapping method is used to reduce the input dimension, the network size, and learning time of BP neural network. Finally, a shuffled cuckoo search algorithm is adopted to optimize the BP neural network soft-sensor model. Simulation results show that the model has better generalization results and prediction accuracy. PMID:25133210

New Jersey Environmental Digital Library  

NSDL National Science Digital Library

Developed by the Scholarly Communication Center of Rutgers University Libraries, this site offers access to an impressive array of materials related to the New Jersey environment. The scope of the collection is quite broad, including citizen information, technical reports, photographic tours, and even some full-length videos. In addition, many of the items in the digital library are ephemeral or grey literature, typically unavailable through common research tools. Visitors may search the collection by keyword or phrase, title, or author, or browse via one of three pull-down menus: theme, place (county), and document type. As if all this were not enough, the library will also digitize documents on demand, and environmental organizations and individual researchers can submit their materials directly to the collection (select "submit records" for instructions). An excellent resource and a model for other states.

Medical library services in Kuwait: history and future prospects.  

PubMed Central

Despite immense resources and a growing interest in education and libraries, library development in Kuwait has been restricted by the problems common to all developing countries. These include an overdose of bureaucracy, lack of trained librarians, and little perception of the library's importance in the educational system. Medical librarianship is virtually a new field. The only medical library of any significance in the country is the Faculty of Medicine Library established in 1974 to serve the newly organized Faculty of Medicine of Kuwait University. In recent years, the Faculty of Medicine Library has gone through several reassessments and many changes. It has expanded its collection, begun computerized searching, and recruited several professional librarians. Now semiautonomous from the university's Libraries Department and housed in a new, modern building, the library has the potential to become the main medical library in the Persian Gulf area.

Deep search for companions to probable young brown dwarfs. VLT/NACO adaptive optics imaging using IR wavefront sensing  

NASA Astrophysics Data System (ADS)

Aims: We have obtained high contrast images of four nearby, faint, and very low mass objects 2MASS J04351455-1414468, SDSS J044337.61+000205.1, 2MASS J06085283-2753583 and 2MASS J06524851-5741376 (hereafter 2MASS0435-14, SDSS0443+00, 2MASS0608-27 and 2MASS0652-57), identified in the field as probable isolated young brown dwarfs. Our goal was to search for binary companions down to the planetary mass regime. Methods: We used the NAOS-CONICA adaptive optics instrument (NACO) and its unique capability to sense the wavefront in the near-infrared to acquire sharp images of the four systems in Ks, with a field of view of 28'' × 28''. Additional J and L' imaging and follow-up observations at a second epoch were obtained for 2MASS0652-57. Results: With a typical contrast ?Ks = 4.0-7.0 mag, our observations are sensitive down to the planetary mass regime considering a minimum age of 10 to 120 Myr for these systems. No additional point sources are detected in the environment of 2MASS0435-14, SDSS0443+00 and 2MASS0608-27 between 0.1-12'' (i.e. about 2 to 250 AU at 20 pc). 2MASS0652-57 is resolved as a ~230 mas binary. Follow-up observations reject a background contaminate, resolve the orbital motion of the pair, and confirm with high confidence that the system is physically bound. The J, Ks and L' photometry suggest a q ~ 0.7-0.8 mass ratio binary with a probable semi-major axis of 5-6 AU. Among the four systems, 2MASS0652-57 is probably the less constrained in terms of age determination. Further analysis would be necessary to confirm its youth. It would then be interesting to determine its orbital and physical properties to derive the system's dynamical mass and to test evolutionary model predictions. Based on observations collected at the European Southern Observatory, Chile (ESO programmes 076.C-0554(A), 076.C-0554(B) and 085.C-0257(A).

A New Unsupervised Change Detection Approach Based On DWT Image Fusion And Backtracking Search Optimization Algorithm For Optical Remote Sensing Data  

NASA Astrophysics Data System (ADS)

Change detection is one of the most important subjects of remote sensing discipline. In this paper, a new unsupervised change detection approach is proposed for multi-temporal remotely sensed optic imagery. This approach does not require any prior information about changed and unchanged pixels. The approach is based on Discrete Wavelet Transform (DWT) based image fusion and Backtracking Search Optimization Algorithm (BSA). In the first step of the approach, absolute-valued difference image and absolute-valued log-ratio image is calculated from co-registered and radiometrically corrected multi-temporal images. Then, these difference images are fused using DWT. The fused image is filtered by median filter for edge information preservation and by wiener filter for image smoothing. Then, a min-max normalization is applied to the filtered data. The normalized data is clustered into two groups with BSA as changed and unchanged pixels by minimizing an objective function, unlike classical methods using CVA, PCA, FCM or K-means techniques. To show effectiveness of proposed approach, two remote sensing data sets, Sardinia and Mexico, are used. False Alarm, Missed Alarm, Total Alarm and Total Error Rate are selected as performance criteria to evaluate the effectiveness of new approach using ground truth images. Experimental results show that proposed approach is effective for unsupervised change detection of optical remote sensing data.

HiTIDE: An Extensible Service-Based Web Interface for the Search, Imaging, and Extraction of Swath-based Geophysical Parameters  

NASA Astrophysics Data System (ADS)

PO.DAAC's High-level Tool for Interactive Data Extraction(HiTIDE) is a web interface powered by a trio of services that facilitate efficient search, image, and extract capabilities for Level 2 swath satellite ocean data products in HDF and NetCDF data formats. HiTIDE provides both an intuitive user interface for direct human access to the data and a discoverable application programming interface via standards-based web services (OpenSearch, WMS). The key component to HiTIDE's capabilities is a backend tile database that supports precise spatial and temporal search functionality at a sub-granular resolution. With HiTIDE's architecture, science users can efficiently find, evaluate, and download subsetted science data products interactively or programmatically. As a system, HiTIDE represents a framework that can ingest virtually any OPeNDAP-enabled geolocated data product. This presentation will provide an overview of the HiTIDE GUI and its underlying web services plus a discussion of the future direction of development such as Level 3 data product support, enabling data-specific search constraints, and enhanced imaging capabilities.

Jewish National and University Library Kettubot Database  

NSDL National Science Digital Library

"For over 2000 years Jewish law has required that every husband present his wife, at the time of their marriage, with a marriage contract or ketubbah, guaranteeing the wife's financial rights in case of the husband's death or divorce." These Kettubot are a rich source for studying Jewish history, customs, and art, as many were decorated according to the locality and period and reflected local customs. In addition, each was a legal document with exact dates and place names, allowing historians to identify them precisely in time and place. The Jewish National and University Library (JNUL) has the largest collection of Kettubot in the world, with over 1,200 items. They have now created an online database of these documents, allowing scholars and others worldwide to access images and bibliographic information. Visitors may browse the collection by country or search by keyword. Images of the Kettubot are available in three resolutions, and bibliographic records include title, place, country, year, material, and size. The names of the parties to the contract and witnesses are also listed, but they appear to be in Hebrew, and users will need the appropriate language capability in their browsers.

The Library of Congress new World Wide Web server, the first step in the Library's Electronic Digital Library project. The first collections include approximately 4000 prints and photographs from the American Memory project, and Country Studies from the Federal Research Division. All collections are searchable through an advanced text retrieval system. Also available is an Online Exhibits Program of exhibits on display at the Library. The Library's Home Page also provides a connection to LC MARVEL(the Library's gopher-based campus-wide information system ) and LOCIS (the Library's database retrieval system ).

Networked Computer Science Technical Reports Library  

NSDL National Science Digital Library

The goal of the Networked Computer Science Technical Report Library (NCSTRL, pronounced "ancestral") is to provide access to research papers produced at over 60 computer science departments and laboratories worldwide. Users may browse an institution's collection by author or year of publication, or may search through either a simple or an advanced interface. The site aims to advance the field of CS through resource sharing and by exploring related implementation issues. A word of caution: unless using a singular, unique term, avoid the simple search method since "or" operators are implied. Your best bet for searching multiple terms is the advanced search option.

Computational wave optics library for C++: CWO++ library  

NASA Astrophysics Data System (ADS)

Diffraction calculations, such as the angular spectrum method and Fresnel diffractions, are used for calculating scalar light propagation. The calculations are used in wide-ranging optics fields: for example, Computer Generated Holograms (CGHs), digital holography, diffractive optical elements, microscopy, image encryption and decryption, three-dimensional analysis for optical devices and so on. However, increasing demands made by large-scale diffraction calculations have rendered the computational power of recent computers insufficient. We have already developed a numerical library for diffraction calculations using a Graphic Processing Unit (GPU), which was named the GWO library. However, this GWO library is not user-friendly, since it is based on C language and was also run only on a GPU. In this paper, we develop a new C++ class library for diffraction and CGH calculations, which is referred to as a CWO++ library, running on a CPU and GPU. We also describe the structure, performance, and usage examples of the CWO++ library.

User Expectations in the Time of Google: Usability Testing of Federated Searching  

Microsoft Academic Search

As libraries expand their services into the world of federated searching, librarians need to work with users to discover what their expectations are and how the library can customize the software to meet users' expectations. This article describes the user testing performed at Texas A&M University during 2005 as the libraries implemented a new federated
