    PubMed Central

    Kass, Robert E.

    2011-01-01

    Statistics has moved beyond the frequentist-Bayesian controversies of the past. Where does this leave our ability to interpret results? I suggest that a philosophy compatible with statistical practice, labelled here statistical pragmatism, serves as a foundation for inference. Statistical pragmatism is inclusive and emphasizes the assumptions that connect statistical models with observed data. I argue that introductory courses often mis-characterize the process of statistical inference and I propose an alternative “big picture” depiction. PMID:21841892

  4. The Big Picture Book of Viruses

    NSDL National Science Digital Library

    "The Big Picture Book of Viruses is intended to serve as both a catalog of virus pictures on the Internet and as an educational resource to those users seeking more information about viruses," claims the site's founder, Dr. Robert F. Garry of Tulane University School of Medicine. From the left-hand column of Big Picture Book's homepage, you can access color images of viruses by name, structure/genome, host, or associated disease (the images are held on external Websites from a variety of research institutions). Many of the images are from electron microscopes or x-ray diffractors, and others are computer-generated simulations or prepared specimen slides. Along with mug shots of Nucleopolyhedrovirus, Lipothrixvirus and Chlamydiamicrovirus, to name just a few, comes a wealth of text and links. Links take users to sites on virus structure, viral taxonomy, Web courses, tutorials, and much more. Besides The Big Picture Book of Viruses, Dr. Garry maintains a Website entitled All the Virology on the Web, that Scout Project editors discovered and reviewed in its infancy in the November 17, 1995 _Scout Report.

  11. Using Graphical Processing Units to Accelerate Orthorectification, Atmospheric Correction and Transformations for Big Data

    NASA Astrophysics Data System (ADS)

    O'Connor, A. S.; Justice, B.; Harris, A. T.

    2013-12-01

    Graphics Processing Units (GPUs) are high-performance multiple-core processors capable of very high computational speeds and large data throughput. Modern GPUs are inexpensive and widely available commercially. These are general-purpose parallel processors with support for a variety of programming interfaces, including industry standard languages such as C. GPU implementations of algorithms that are well suited for parallel processing can often achieve speedups of several orders of magnitude over optimized CPU codes. Significant improvements in speeds for imagery orthorectification, atmospheric correction, target detection and image transformations like Independent Components Analsyis (ICA) have been achieved using GPU-based implementations. Additional optimizations, when factored in with GPU processing capabilities, can provide 50x - 100x reduction in the time required to process large imagery. Exelis Visual Information Solutions (VIS) has implemented a CUDA based GPU processing frame work for accelerating ENVI and IDL processes that can best take advantage of parallelization. Testing Exelis VIS has performed shows that orthorectification can take as long as two hours with a WorldView1 35,0000 x 35,000 pixel image. With GPU orthorecification, the same orthorectification process takes three minutes. By speeding up image processing, imagery can successfully be used by first responders, scientists making rapid discoveries with near real time data, and provides an operational component to data centers needing to quickly process and disseminate data.

    2009-03-01

    The coastal waters of American Samoa's five high islands (Tutuila, Aunu'u, Ofu, Olosega, and Ta'u) were surveyed in 2004 using a probabilistic design. Water quality data were collected from the near-shore coastal habitat, defined as all near-shore coastal waters including embayments, extending out to 1/4 mile off-shore. Hydrography and water column samples were collected, and water quality data were compared to the Territorial water quality standards for pH, dissolved oxygen (DO), Enterococcus, chlorophyll a, water clarity, total nitrogen, and total phosphorus. All station measurements for pH, DO, and Enterococcus satisfied the local water quality standards, although some fraction of the Territory could not be assessed for either DO or Enterococcus. With respect to chlorophyll a, 66 +/- 18% of Territory coastal waters complied with the standard, while 34 +/- 18% failed to comply with the standard. For water clarity, 54 +/- 18% of the Territorial waters complied with the standard while 42 +/- 7% failed to comply. Territorial waters satisfied the standards for total nitrogen and phosphorus 72 +/- 17% and 92 +/- 10%, respectively. These data provide the first "big-picture" view of water quality in the near shore region around the high islands of American Samoa. While the picture is encouraging, these data suggest emerging water quality concerns. PMID:19082748

    In marine navigation systems, the three-dimensional (3D) visualization is often and often used. Echosonders and sonars working in hydroacustic systems can present pictures in three dimensions. Currently, vector maps also offer 3D presentation. This presentation is used in aviation and underwater navigation. In the nearest future three-dimensional presentation may be obligatory presentation in displays of navigation systems. A part of these systems work with radar and communicates with it transmitting data in a digital form. 3D presentation of radar picture require a new technology to develop. In the first step it is necessary to compile digital form of radar signal. The modern navigation radar do not present data in three-dimensional form. Progress in technology of digital signal processing make it possible to create multidimensional radar pictures. For instance, the RSC (Radar Scan Converter) - digital radar picture recording and transforming tool can be used to create new picture online. Using RSC and techniques of modern computer graphics multidimensional radar pictures can be generated. The radar pictures mentioned should be readable for ECDIS. The paper presents a method for generating multidimensional radar picture from original signal coming from radar receiver.

    This short review explores the large gap between clinical issues and basic science, and suggests why tuberculosis research should focus on redirect the immune system and not only on eradicating Mycobacterium tuberculosis bacillus. Along the manuscript, several concepts involved in human tuberculosis are explored in order to understand the big picture, including infection and disease dynamics, animal modeling, liquefaction, inflammation and immunomodulation. Scientists should take into account all these factors in order to answer questions with clinical relevance. Moreover, the inclusion of the concept of a strong inflammatory response being required in order to develop cavitary tuberculosis disease opens a new field for developing new therapeutic and prophylactic tools in which destruction of the bacilli may not necessarily be the final goal.

    PubMed

    Konstantinidis, Evdokimos I; Frantzidis, Christos A; Pappas, Costas; Bamidis, Panagiotis D

    2012-07-01

    In this paper the feasibility of adopting Graphic Processor Units towards real-time emotion aware computing is investigated for boosting the time consuming computations employed in such applications. The proposed methodology was employed in analysis of encephalographic and electrodermal data gathered when participants passively viewed emotional evocative stimuli. The GPU effectiveness when processing electroencephalographic and electrodermal recordings is demonstrated by comparing the execution time of chaos/complexity analysis through nonlinear dynamics (multi-channel correlation dimension/D2) and signal processing algorithms (computation of skin conductance level/SCL) into various popular programming environments. Apart from the beneficial role of parallel programming, the adoption of special design techniques regarding memory management may further enhance the time minimization which approximates a factor of 30 in comparison with ANSI C language (single-core sequential execution). Therefore, the use of GPU parallel capabilities offers a reliable and robust solution for real-time sensing the user's affective state. PMID:22520825

  4. GKS -- Graphical Kernel System

    NASA Astrophysics Data System (ADS)

    Terrett, D. L.

    This note describes the release on Starlink of the RAL/ICL GKS graphics package. GKS has two major advantages over other graphics packages: o It is an international standard and real portability of graphics software is now possible. An illustration of this is that the NCAR package---an extensive library of scientific graphics utilities produced by the National Center for Atmospheric Research in the USA---runs on the RAL/ICL GKS without any modification, despite the fact that it was developed using a completely independent GKS implementation. o No other package provides the ability to write device independent graphics programs to the extent that GKS does. Only with GKS can you write a program that will run, and produce good pictures, on all devices supported by the implementation, including devices not supported at the time the program was written. Programs can nonetheless still fully exploit all the facilities offered by the hardware.

    2015-07-01

    The epidemic of overweight and obesity presents a major challenge to chronic disease prevention and health across the life course around the world. Fueled by economic growth, industrialization, mechanized transport, urbanization, an increasingly sedentary lifestyle, and a nutritional transition to processed foods and high-calorie diets over the last 30 years, many countries have witnessed the prevalence of obesity in its citizens double and even quadruple. A rising prevalence of childhood obesity, in particular, forebodes a staggering burden of disease in individuals and healthcare systems in the decades to come. A complex, multifactorial disease, with genetic, behavioral, socioeconomic, and environmental origins, obesity raises the risk of debilitating morbidity and mortality. Relying primarily on epidemiologic evidence published within the last decade, this non-exhaustive review discusses the extent of the obesity epidemic, its risk factors-known and novel-, sequelae, and economic impact across the globe.

    Colonoscopy for average-risk colorectal cancer screening has transformed the practice of gastrointestinal medicine in the United States. However, although the dominant screening strategy, its use is not supported by randomized controlled trials. Observational data do support a protective effect of colonoscopy and polypectomy on colorectal cancer incidence and mortality, but the level of protection in the proximal colon is variable and operator-dependent. Colonoscopy by high-level detectors remains highly effective, and ongoing quality improvement initiatives should consider regulatory factors that motivate changes in physician behavior.

    The cover picture shows how both, fine arts and science, avail themselves of a system of intertwined symbolic and iconic languages. They make use of a common set of abstracted signs to report on their results. Thus, already in 1925, Wassily Kandinsky painted a masterpiece (bottom), which now, 75 years later, might be regarded as a blueprint for a scientific project. In his painting, Kandinsky pictured a grid-shaped sign that resembles in effect an actual molecular switch. Apparently following an enigmatic protocol, the groups of Lehn and Gütlich (see p. 2504 ff. for more details) constructed a grid-type inorganic architecture that operates as a three-level magnetic switch (center) triggered by three external perturbations (p, T, hnu). The switching principle is based on the spin-crossover phenomenon of Fe(II) ions and can be monitored by Mössbauer spectroscopy (left) and magnetic measurements (rear). Maybe not by chance, the English translation of the title of the painting "signs" is a homonym of "science", since both presented works are a product of the insatiable curiosity of man and his untiring desire to recognize his existence.

  3. Computer Graphics & Digital Animation

    NSDL National Science Digital Library

    2003-01-01

    Computer graphics is a term that encompasses a wide range of sciences and techniques. To understand some of the processes involved in generating computer graphics, Cornell University offers this detailed introduction to the subject (1). The site contains explanations and a series of pictures that illustrate object rendering, shading, ray tracing, and more. Computer graphics has seen rapid advancements in the past few years, partly because of the development of dedicated graphics processing units (GPUs). The performance of GPUs has outpaced that of general purpose processors, and this has sparked interest in using GPUs for applications other than graphics. General Purpose Computation Using Graphics Hardware (2) is a site that examines this trend. It is regularly updated with news, links to conferences and research papers, and related projects. The Center for Human Modeling and Simulation (3) is a research effort at the University of Pennsylvania. Many of the center's projects can be browsed on its website, including animation of physical gestures and the development of virtual humans. As a testament to the intricacy involved in modern computer graphics, this paper (4) describes a new technique for modeling the shine of light off human hair. The authors compare the results of their work to current shading practices and show notable improvements in the realism of the model. Three dimensional photography, a recent extension of computer graphics, has received significant attention from its use in movies. This paper (5) proposes a number of strategies for improving the accuracy and flexibility of current approaches to 3D photography. The 30th annual SIGGRAPH conference, held in July 2003 and sponsored by the Association for Computing Machinery, is one of the most well known conferences related to computer graphics. The SIGGRAPH Web Expo (6) showcases some of the most outstanding web-graphics work of the year. Visitors can choose between seven different categories and view many interactive and visually stunning creations. Some of the works have strict hardware and software requirements that are required in order to view them, however. This online review of the SIGGRAPH conference (7) provides an interesting view into the events and presentations. Scattered throughout the text are examples of computer generated images, as well as links to some of the papers and projects that were featured. Lastly, this news article (8) introduces machinima, a term used to describe special effects in movies that are created with technologies originally developed for computer games. The Machinima Film Festival 2003 is the basis of the article.

  12. Geology’s “Super Graphics” and the Public: Missed Opportunities for Geoscience Education

    NASA Astrophysics Data System (ADS)

    Clary, R. M.; Wandersee, J. H.

    2009-12-01

    The geosciences are very visual, as demonstrated by the illustration density of maps, graphs, photographs, and diagrams in introductory textbooks. As geoscience students progress, they are further exposed to advanced graphics, such as phase diagrams and subsurface seismic data visualizations. Photographs provide information from distant sites, while multivariate graphics supply a wealth of data for viewers to access. When used effectively, geology graphics have exceptional educational potential. However, geological graphic data are often presented in specialized formats, and are not easily interpreted by an uninformed viewer. In the Howe-Russell Geoscience Complex at Louisiana State University, there is a very large graphic (~ 30 ft x 6 ft) exhibited in a side hall, immediately off the main entrance hall. The graphic, divided into two obvious parts, displays in its lower section seismic data procured in the Gulf of Mexico, from near offshore Louisiana to the end of the continental shelf. The upper section of the graphic reveals drilling block information along the seismic line. Using Tufte’s model of graphic excellence and Paivio’s dual-coding theory, we analyzed the graphic in terms of data density, complexity, legibility, format, and multivariate presentation. We also observed viewers at the site on 5 occasions, and recorded their interactions with the graphic. This graphic can best be described as a Tufte “super graphic.” Its data are high in density and multivariate in nature. Various data sources are combined in a large format to provide a powerful example of a multitude of information within a convenient and condensed presentation. However, our analysis revealed that the graphic misses an opportunity to educate the non-geologist. The information and seismic “language” of the graphic is specific to the geology community, and the information is not interpreted for the lay viewer. The absence of title, descriptions, and symbol keys are detrimental. Terms are not defined. The absence of color keys and annotations is more likely to lead to an appreciation of graphic beauty, without concomitant scientific understanding. We further concluded that in its current location, constraints of space and reflective lighting prohibit the viewer from simultaneously accessing all subsurface data in a “big picture” view. The viewer is not able to fully comprehend the macro/micro aspects of the graphic design within the limited viewing space. The graphic is an example of geoscience education possibility, a possibility that is currently undermined and unrealized by lack of interpretation. Our analysis subsequently informed the development of a model to maximize the graphic’s educational potential, which can be applied to similar geological super graphics for enhanced public scientific understanding. Our model includes interactive displays that apply the auditory-visual dual coding approach to learning. Notations and aural explanations for geological features should increase viewer understanding, and produce an effective informal educational display.

    A centralized computer graphics system is being developed at the NASA Langley Research Center. This system was required to satisfy multiuser needs, ranging from presentation quality graphics prepared by a graphic artist to 16-mm movie simulations generated by engineers and scientists. While the major thrust of the central graphics system was directed toward engineering and scientific applications, hardware and software capabilities to support the graphic artists were integrated into the design. This paper briefly discusses the importance of computer graphics in research; the central graphics system in terms of systems, software, and hardware requirements; the application of computer graphics to graphic arts, discussed in terms of the requirements for a graphic arts workstation; and the problems encountered in applying computer graphics to the graphic arts. The paper concludes by presenting the status of the central graphics system.

    We show how to hang a picture by wrapping rope around n nails, making a polynomial number of twists, such that the picture falls whenever any k out of the n nails get removed, and the picture remains hanging when fewer than k nails get removed. This construction makes for some fun mathematical magic performances. More generally, we characterize the possible Boolean functions characterizing when the picture falls in terms of which nails get removed as all monotone Boolean functions. This construction requires an exponential number of twists in the worst case, but exponential complexity is almost always necessary for general functions.

  15. Graphic Groundwater

    NSDL National Science Digital Library

    Laura Sanders

    Graphic Groundwater (GGW) is a graphical user-interface for the USGS ground water modeling code MODFLOW. It allows the user to start with a topographic map, build a model grid directly on the map, enter hydraulic properties into grid cells as one would into a spreadsheet, click on the grid to enter the positions of water wells, and (among other things) track imaginary "particles" that would flow into the well from the surrounding area. GGW was created by Steve Esling at Southern Illinois University/Carbondale. Students delineate the area from which a well will draw recharge during a five-year period. It's a practical problem and one that allows them to put together geologic skills (reading maps, drawing cross sections) with hydrogeologic concepts (recharge area, ground water flow, hydraulic properties of earth materials) to produce something that would be meaningful to a community zoning or planning board. The students control the whole look and shape of the visualization and can alter variables at will to experiment with how each change affects ground water flow.

    The benefits of using computer graphics in design are briefly reviewed. It is shown that computer graphics substantially aids productivity by permitting errors in design to be found immediately and by greatly reducing the cost of fixing the errors and the cost of redoing the process. The possibilities offered by computer-generated displays in terms of information content are emphasized, along with the form in which the information is transferred. The human being is ideally and naturally suited to dealing with information in picture format, and the content rate in communication with pictures is several orders of magnitude greater than with words or even graphs. Since science and engineering involve communicating ideas, concepts, and information, the benefits of computer graphics cannot be overestimated.

    2009-10-01

    Social work has struggled with image problems and misperceptions of the profession and the types of services it provides. Photography is a medium that has been used effectively by other professions to change attitudes and perceptions. The present study examined the potential of photographs to change the image of available social services--namely, an adult day care program. Participants were divided into two groups: (1) a control group that only completed a survey on attitudes about adult day care services and (2) an experimental group that viewed photographs showing positive images of clients engaged in program activities before taking the survey. A multivariate regression demonstrated that those who saw the photographs before taking the survey had more positive attitudes about adult day care services. In fact, the variable representing the presentation of the photographs had the strongest effect on attitudes. Such findings suggest that photography is a potentially powerful tool to promote positive attitudes about social services programs. The implications of these results are discussed. PMID:19780462

    At least once, every consultant, technologist, engineer and budding system analyst has modeled an industry activity in solving an operational or control problem. For the electrical engineer, these models assist in solving complex network topology problems and in improving plant efficiencies. From an operations and technology viewpoint, they provide a tool for focusing on the products of the electrical utility and are typically described with activity flowcharts, business objectives, and, more recently, by workflow, business process descriptions, and information-data flows. Each perspective has merit, and, indeed, is generated through some rational process. Some models focus on a key aspect of the industry, such as customer service, fuel strategy, or environmental compliance. Although most approaches will help a utility to become sensitized to competition and market directions, many utilities will need to take decisive action to respond to their competitors actions to gain market share, and educate their customers regarding new {open_quotes}utility products{close_quotes}. The U.S. Gap Industry and the U.K.`s Electric Industry have already begun to put the pieces of this puzzle together. Focused process improvements coordinated with the application of relevant information technology are creating the basis for continued business development and delivery of new products. Supporting these new, value-added offerings, the development of user-friendly solutions that span the breadth of the utility enterprise has already commenced. This paper phrases process modeling, information technology, and products in terms familiar to the utility industry. Common experiences and common sense are applied to customer-focused process and information technology solutions facilitating the successful delivery of {open_quotes}utility products{close_quotes}.

  11. Managing the Nuclear Fuel Cycle, The Big Picture

    SciTech Connect

    Brett W Carlsen

    2010-07-01

    The nuclear industry, at least in the United States, has failed to deliver on its promise of cheap, abundant energy. After pioneering the science and application and becoming a primary exporter of nuclear technologies, domestic use of nuclear power fell out-of-favor with the public and has been relatively stagnant for several decades. Recently, renewed interest has generated optimism and talk of a nuclear renaissance characterized by a new generation of safe, clean nuclear plants in this country. But, as illustrated by recent policy shifts regarding closure of the fuel cycle and geologic disposal of high-level radioactive wastes, significant hurdles have yet to be overcome. Using the principles of system dynamics, this paper will take a holistic look at the nuclear industry and the interactions between the key players to explore both the intended and unintended consequences of efforts to address the issues that have impeded the growth of the industry and also to illustrate aspects which must be effectively addressed if the renaissance of our industry is to be achieved and sustained.

  12. Results of reoperation for hip dislocation: the big picture.

    PubMed

    Morrey, Bernard F

    2004-12-01

    Hip instability remains a costly complication of primary (3%) and revision (10%) procedures. In those with well-oriented components, instability may be anticipated in about 70% from advancement of the trochanter. Articular reorientation readily is affected by the use of modular cups with elevated rims. This has proven to be an effective strategy both to lessen the likelihood of an initial dislocation after both primary and revision procedures. It has also proven to be an effective strategy to treat the unstable implant, especially if cup orientation has been defined as the primary problem. Larger head sizes in the range of low-friction arthroplasty, such as 32 mm, are not any more stable than 22-mm diameter implants. Anatomic-sized heads as used in bipolar devices are effective in treating established instability in up to 90% of instances. The most popular current option is that of the constrained head/cup articulation. Good short-term results have revealed success in more than 90%. However, the effectiveness is design dependent, and the long-term effectiveness understandably is questioned as reports of mechanical failure begin to emerge. PMID:15577472

    A mathematician, David R. Hedgley, Jr. developed a computer program that considers whether a line in a graphic model of a three-dimensional object should or should not be visible. Known as the Hidden Line Computer Code, the program automatically removes superfluous lines and displays an object from a specific viewpoint, just as the human eye would see it. An example of how one company uses the program is the experience of Birdair which specializes in production of fabric skylights and stadium covers. The fabric called SHEERFILL is a Teflon coated fiberglass material developed in cooperation with DuPont Company. SHEERFILL glazed structures are either tension structures or air-supported tension structures. Both are formed by patterned fabric sheets supported by a steel or aluminum frame or cable network. Birdair uses the Hidden Line Computer Code, to illustrate a prospective structure to an architect or owner. The program generates a three- dimensional perspective with the hidden lines removed. This program is still used by Birdair and continues to be commercially available to the public.

  9. Methods For Electronic 3-D Moving Pictures Without Glasses

    Collender, Robert B.

    1987-06-01

    This paper describes implementation approaches in image acquisition and playback for 3-D computer graphics, 3-D television and 3-D theatre movies without special glasses. Projection lamps, spatial light modulators, CRT's and dynamic scanning are all eliminated by the application of an active image array, all static components and a semi-specular screen. The resulting picture shows horizontal parallax with a wide horizontal view field (up to 360 de-grees) giving a holographic appearance in full color with smooth continuous viewing without speckle. Static component systems are compared with dynamic component systems using both linear and circular arrays. Implementation of computer graphic systems are shown that allow complex shaded color images to extend from the viewer's eyes to infinity. Large screen systems visible by hundreds of people are feasible by the use of low f-stops and high gain screens in projection. Screen geometries and special screen properties are shown. Viewing characteristics offer no restrictions in view-position over the entire view-field and have a "look-around" feature for all the categories of computer graphics, television and movies. Standard video cassettes and optical discs can also interface the system to generate a 3-D window viewable without glasses. A prognosis is given for technology application to 3-D pictures without glasses that replicate the daily viewing experience. Super-position of computer graphics on real-world pictures is shown feasible.

This inhibits the focusing of geodesics and possibly cause non-focusing of the geodesics. This feature is translated into the situation in which the universe has an infinite age and hence no beginning avoiding the big bang singularity.

    This research was designed to observe whether parents guide their children's understanding of spatial-graphic representations and, if so, to describe the quality of the strategies they use. Parents read a picture book to their preschoolers (3 or 5 years, N=31) and children completed spatial-graphic comprehension tasks. Observational data revealed a range of creative behaviors used to address the book's spatial-graphic challenges. The incidence and quality of parental spatial-graphic behaviors were significantly related to 5-year-old children's performance on spatial-graphic measures. These findings, as well as the paucity of parent attention to aesthetics or graphic production techniques, are discussed in relation to representational development and educational practice.

    2014-12-01

    The environmental impact of coal mining and burning of coal is evident and generally easy to understand. However, students often struggle to understand the social impacts of coal mining. A jigsaw activity culminating in a mock town hall meeting helps students link social, economic and environmental impacts of coal mining. Students are divided into four groups and assigned the task of researching the environmental, social, economic or health impacts of coal mining in West Virginia. When students have completed the research, they are assigned a role for the town hall. Roles include local community members, direct employees of the coal industry, business owners from industries related to coal mining, and environmentalists. One student from each research area is assigned to each role, forcing students to consider environmental, social, health and economic aspects of coal mining in choosing an appropriate position for their role. Students have 30 minutes to prepare their positions and then present for 2-5 minutes in the simulated town hall. We then have open class discussion and review the positions. Finally, students are required to write a letter to the editor of the local paper. The specific topic for the town hall and letters can be varied based on current events and could include new regulations on power plants, mine safety, government funding of alternative energy supplies or a range of other topics. This approach forces students to consider all aspects of the issue. In addition, because students have to assume a role, they are more aware of the direct impact that coal mining has on individuals' lives.

    We clarify the controversy over the coherent-state (CS) versus the number-state (NS) pictures in quantum optics. The NS picture is equivalent to the CS picture, as long as the phases $\\phi$ in the laser fields are randomly distributed, as M{\\o}lmer argues [\\pra {\\bf 55}, 3195 (1997)]. However, the claim by Rudolph and Sanders [Phys. Rev. Lett. {\\bf 87}, 077903 (2001)] has a few gaps. First, they make an assumption that is not necessarily true in the calculation of a density operator involved with a two-mode squeezed state. We show that there exists entanglement in the density operator without defying the assumption that phases are randomly distributed. Moreover, using a concept of picture-invariance, we argue that it is not that criteria for quantum teleportation are not satisfied. We discuss an analogy between the controversy on the CS versus NS pictures to that on the heliocentric versus geocentric pictures.

    Designing effective presentations of technical information is extremely difficult and time-consuming. Moreover, the combination of increasing task complexity and declining job skills makes the need for high-quality technical presentations especially urgent. We believe that this need can ultimately be met through the development of knowledge-based graphical interfaces that can design and present technical information. Since much material is most naturally communicated through pictures, our work has stressed the importance of well-designed graphics, concentrating on generating pictures and laying out displays containing them. We describe APEX, a testbed picture generation system that creates sequences of pictures that depict the performance of simple actions in a world of 3D objects. Our system supports rules for determining automatically the objects to be shown in a picture, the style and level of detail with which they should be rendered, the method by which the action itself should be indicated, and the picture's camera specification. We then describe work on GRIDS, an experimental display layout system that addresses some of the problems in designing displays containing these pictures, determining the position and size of the material to be presented.

    In 4 experiments we showed that picture naming latencies are affected by beliefs about the task concurrently performed by another speaker. Participants took longer to name pictures when they believed that their partner concurrently named pictures than when they believed their partner was silent (Experiments 1 and 4) or concurrently categorized the pictures as being from the same or from different semantic categories (Experiment 2). However, picture naming latencies were not affected by beliefs about what one's partner said, as it did not matter whether participants believed their partner produced the same utterance, or an utterance that differed by ordering (Experiments 1 and 2) or lexical content (Experiments 3 and 4). These findings are consistent with the proposal that speakers represent whether another speaker is preparing to speak but not what they are preparing to say. PMID:25089740

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by the procedure of double analytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry. In the dual Yang-Mills theory description, these are nonsingular as the coupling goes to zero in the N=4 super Yang-Mills theory. The cosmological singularities simply signal the failure of the supergravity description of the full type IIB superstring theory.

    The field of computer graphics is rapidly opening up to the graphic artist. It is not necessary to be a programming expert to enter this fascinating world. The capabilities of the medium are astounding: neon and metallic effects, translucent plastic and clear glass effects, sensitive 3-D shadings, limitless textures, and above all color. As with any medium, computer graphics has its advantages, such as speed, ease of form manipulation, and a variety of type fonts and alphabets. It also has its limitations, such as data input time, final output turnaround time, and not necessarily being the right medium for the job at hand. And finally, it is the time- and cost-saving characteristics of computer-generated visuals, opposed to original artwork, that make computer graphics a viable alternative. This paper focuses on parts of the computer graphics system in use at the Los Alamos National Laboratory to provide specific examples.

    2014-01-01

    Graphical models provide a rich framework for summarizing the dependencies among variables. The graphical lasso approach attempts to learn the structure of a Gaussian graphical model (GGM) by maximizing the log likelihood of the data, subject to an l1 penalty on the elements of the inverse co-variance matrix. Most algorithms for solving the graphical lasso problem do not scale to a very large number of variables. Furthermore, the learned network structure is hard to interpret. To overcome these challenges, we propose a novel GGM structure learning method that exploits the fact that for many real-world problems we have prior knowledge that certain edges are unlikely to be present. For example, in gene regulatory networks, a pair of genes that does not participate together in any of the cellular processes, typically referred to as pathways, is less likely to be connected. In computer vision applications in which each variable corresponds to a pixel, each variable is likely to be connected to the nearby variables. In this paper, we propose the pathway graphical lasso, which learns the structure of a GGM subject to pathway-based constraints. In order to solve this problem, we decompose the network into smaller parts, and use a message-passing algorithm in order to communicate among the subnetworks. Our algorithm has orders of magnitude improvement in run time compared to the state-of-the-art optimization methods for the graphical lasso problem that were modified to handle pathway-based constraints.

    PubMed Central

    2008-01-01

    Four experiments revealed arousal-enhanced location memory for pictures. After an incidental encoding task, participants were more likely to remember the locations of positive and negative arousing pictures than the locations of non-arousing pictures, indicating better binding of location to picture. This arousal-enhanced binding effect did not have a cost for the binding of nearby pictures to their locations. Thus, arousal can enhance binding of an arousing picture’s content to its location without interfering with picture-location binding for nearby pictures. In addition, arousal-enhanced picture-location memory binding is not just a side effect of enhanced memory for the picture itself, as it occurs both when recognition memory is good and when it is poor.

    2014-11-18

    Cancer graphic narratives, I argue, are part of a medical imaginary that includes representations of difference and biomedical technology that engage Fassin's (2009) concept of biolegitimacy. Framed in three parts, the argument first draws on discourses about cancer graphic narratives from graphic medicine scholars and authors to demonstrate a construction of universal suffering. Second, I examine tropes of hope and difference as a biotechnical embrace. Finally, I consider biosociality within the context of this imaginary and the construction of a meaningful life. Autobiographical graphic narrative as a creative genre that seeks to give voice to individual illness experiences in the context of biomedicine raises anthropological questions about the interplay between the ordinary and biolegitmate. Cancer graphic narratives deconstruct the big events to demonstrate the ordinary ways that a life constructed as different becomes valued through access to medical technologies.

  3. SETI as a part of Big History

    NASA Astrophysics Data System (ADS)

    Maccone, Claudio

    2014-08-01

    Big History is an emerging academic discipline which examines history scientifically from the Big Bang to the present. It uses a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It is taught at some universities. In a series of recent papers ([11] through [15] and [17] through [18]) and in a book [16], we developed a new mathematical model embracing Darwinian Evolution (RNA to Humans, see, in particular, [17] and Human History (Aztecs to USA, see [16]) and then we extrapolated even that into the future up to ten million years (see 18), the minimum time requested for a civilization to expand to the whole Milky Way (Fermi paradox). In this paper, we further extend that model in the past so as to let it start at the Big Bang (13.8 billion years ago) thus merging Big History, Evolution on Earth and SETI (the modern Search for ExtraTerrestrial Intelligence) into a single body of knowledge of a statistical type. Our idea is that the Geometric Brownian Motion (GBM), so far used as the key stochastic process of financial mathematics (Black-Sholes models and related 1997 Nobel Prize in Economics!) may be successfully applied to the whole of Big History. In particular, in this paper we derive Big History Theory based on GBMs: just as the GBM is the “movie” unfolding in time, so the Statistical Drake Equation is its “still picture”, static in time, and the GBM is the time-extension of the Drake Equation. Darwinian Evolution on Earth may be easily described as an increasing GBM in the number of living species on Earth over the last 3.5 billion years. The first of them was RNA 3.5 billion years ago, and now 50 million living species or more exist, each evolving in a statistical way like the GBM stochastic process does. Also Human History may be rewritten in terms of GBMs, as this author did in recent papers just published in the International Journal of Astrobiology and Acta Astronautica. But those mathematical results will not be repeated in this paper in order not to make it too long. Possibly a whole new book about GBMs will be written by the author. Mass Extinctions of the geological past also are one more topic that may be cast in the language of a decreasing GBM over a short time lapse, since Mass Extinctions are sudden all-lows in the number of living species. In this paper, we give formulae for the decreasing GBMs of Mass Extinctions, like the K-Pg one of 64 million years ago. Finally, we note that the Big History Equation is just the extension of the Drake Equation to 13.8 billion years of cosmic evolution. So, the relevant GBM starting at the Big Bang epoch (13.8 billion years ago) and growing up to nowadays in a stochastically increasing fashion becomes the GBM of the number of evolving galaxies populating the Universe. Our Big History model based on the GBM mathematics is thus complete.

The website provides a comprehensive education in all the primary methods used for printing pictures - relief, intaglio, planographic, and photographic. There are eight hours of Benson's recorded lectures available here, along with "additional images and details, allowing visitors to the site to draw their own path through its contents." The lectures conclude with Benson musing about the value of reproducing images.

  10. The Trove: Australia in Pictures

    NSDL National Science Digital Library

    Picture Australia is a cross-collection search tool for finding images from the National Library of Australia and half a dozen other institutions: the National Archives; Australian War Memorial; State Libraries of Victoria, New South Wales, and Tasmania; and the University of Queensland. Librarians and database designers will be interested to know that the cross-collection searching is achieved by using harvested Dublin Core metadata stored in a central index at the National Library, while the digital images remain at their home institutions. Other users will simply be happy to find so many images of Australia, covering a diversity of topics, so easily. There are three ways to approach Picture Australia: picture search, a simple keyword search, or advanced search, which allows users to select and combine Dublin Core elements. In addition, users can follow "trails" to view images culled from all contributing collections, organized around themes, such as Australians and the Olympics (449 images of Olympic history since 1956), Australian Artists (230 portraits of Australian artists), Realia (all kinds of objects from Australian museums, from scrimshaw to costume), or Australian Wildflowers (botanical drawings, photographs, and a few botanists). Images1, the online pictorial collections of the National Library of Australia (reviewed in the October 15, 1999 Scout Report_), is one of the collections that is searched via Picture Australia.

    The increasing availability and growth rate of biomedical information, also known as 'big data', provides an opportunity for future personalized medicine programs that will significantly improve patient care. Recent advances in information technology (IT) applied to biomedicine are changing the landscape of privacy and personal information, with patients getting more control of their health information. Conceivably, big data analytics is already impacting health decisions and patient care; however, specific challenges need to be addressed to integrate current discoveries into medical practice. In this article, I will discuss the major breakthroughs achieved in combining omics and clinical health data in terms of their application to personalized medicine. I will also review the challenges associated with using big data in biomedicine and translational science. PMID:24183925

    Einstein's equation E = mc2 is often said to mean that energy can be converted into matter. More accurately, energy can be converted to matter and antimatter. During the first moments of the Big Bang, the universe was smaller, hotter and energy was everywhere. As the universe expanded and cooled, the energy converted into matter and antimatter. According to our best understanding, these two substances should have been created in equal quantities. However when we look out into the cosmos we see only matter and no antimatter. The absence of antimatter is one of the Big Mysteries of modern physics. In this video, Fermilab's Dr. Don Lincoln explains the problem, although doesn't answer it. The answer, as in all Big Mysteries, is still unknown and one of the leading research topics of contemporary science.

    Recent technological advances allow for high throughput profiling of biological systems in a cost-efficient manner. The low cost of data generation is leading us to the "big data" era. The availability of big data provides unprecedented opportunities but also raises new challenges for data mining and analysis. In this review, we introduce key concepts in the analysis of big data, including both "machine learning" algorithms as well as "unsupervised" and "supervised" examples of each. We note packages for the R programming language that are available to perform machine learning analyses. In addition to programming based solutions, we review webservers that allow users with limited or no programming background to perform these analyses on large data compendia. PMID:24799088

    The "big dog-puppy dog" analogy is a wry visual scheme that helps to explain the nature of resonance structures, delocalized p bonds, and fractional bond orders and formal charges. In this analogy, puppy dogs are restricted to a specific dog run; they represent s-bond electron pairs. Big dogs are allowed to roam freely over several consecutive dog runs; they represent delocalized p-bond electron pairs. By adding a bunny rabbit who is chased by the big dog, the analogy can be expanded to account for delocalized formal charge in a resonance hybrid. This analogy presents a vivid, humorous picture that helps to explain some of the key aspects of resonance.

    In 1833 John Herschel published an account of his graphical method for determining the orbits of double stars. He had hoped to be the first to determine such orbits, but Felix Savary in France and Johann Franz Encke in Germany beat him to the punch using analytical methods. Herschel was convinced, however, that his graphical method was much superior to analytical methods, because it used the judgment of the hand and eye to correct the inevitable errors of observation. Line graphs of the kind used by Herschel became common only in the 1830s, so Herschel was introducing a new method. He also found computation fatiguing and devised a "wheeled machine" to help him out. Encke was skeptical of Herschel's methods. He said that he lived for calculation and that the English would be better astronomers if they calculated more. It is difficult to believe that the entire Scientific Revolution of the 17th century took place without graphs and that only a few examples appeared in the 18th century. Herschel promoted the use of graphs, not only in astronomy, but also in the study of meteorology and terrestrial magnetism. Because he was the most prominent scientist in England, Herschel's advocacy greatly advanced graphical methods.

  8. Picture independent quantum action principle

    SciTech Connect

    Mantke, W.J.

    1992-01-01

    The Schwinger action principle for quantum mechanics is extended into a picture independent form. This displays the quantum connection. Time variations are formulated as variations of a time variable and included into the kinematical variations. Kets and bras represent experimental operations. Experimental operations at different times cannot be identified. The ket and the bra spaces are fiber bundles over time. The same applies to the classical configuration space. For the classical action principle the action can be varied by changing the path or the classical variables. The latter variation of classical functions corresponds to kinematical variations of quantum variables. The picture independent formulation represents time evolution by a connection. A standard experiment is represented by a ket, a connection and a bra. For particular start and end times of experiments, the action and the contraction into a transition amplitude are elements of a new tensor space of quantum correspondents of path functionals. The classical correspondent of the transition amplitude is the probability for a specified state to evolve along a particular path segment. The elements of the dual tensor space represent standard experiments or superpositions thereof. The kinematical variations of the quantum variables are commuting numbers. Variations that include the effect of Poincare or gauge transformations have different commutator properties. The Schwinger action principle is derived from the Feynman path integral formulation. The limitations from the time-energy uncertainty relation might be accommodated by superposing experiments that differ in their start- and end-times. In its picture independent form the action principle can be applied to all superpositions of standard experiments. This may involve superpositions of different connections. The extension of the superposition principle to connections allows representation of a quantum field by a part of the connection.

  9. Before the Big Bang

    NSDL National Science Digital Library

    This radio broadcast explores the cosmological hypothesis known as the cyclical universe, put forward by Neil Turok and Paul Steinhardt. In a cyclical universe, the Big Bang was not the beginning of time and space but merely a cataclysmic event - one of perhaps millions - that takes place from time to time in our universe. The broadcast describes how higher-dimensional, infinitely large parallel sheets called branes could collide together to produce a big bang; how inflation theory solves the puzzle of how the universe is uniform and homogeneous but conflicts with the cyclical universe theory; and how a satellite experiment that will observe patterns in gravity waves may determine whether the predictions of the cyclical universe theory or inflation theory are right. The broadcast is 30 minutes in length.

    Summary Objectives To provide an editorial introduction into the 2014 IMIA Yearbook of Medical Informatics with an overview of the content, the new publishing scheme, and upcoming 25th anniversary. Methods A brief overview of the 2014 special topic, Big Data - Smart Health Strategies, and an outline of the novel publishing model is provided in conjunction with a call for proposals to celebrate the 25th anniversary of the Yearbook. Results ‘Big Data’ has become the latest buzzword in informatics and promise new approaches and interventions that can improve health, well-being, and quality of life. This edition of the Yearbook acknowledges the fact that we just started to explore the opportunities that ‘Big Data’ will bring. However, it will become apparent to the reader that its pervasive nature has invaded all aspects of biomedical informatics – some to a higher degree than others. It was our goal to provide a comprehensive view at the state of ‘Big Data’ today, explore its strengths and weaknesses, as well as its risks, discuss emerging trends, tools, and applications, and stimulate the development of the field through the aggregation of excellent survey papers and working group contributions to the topic. Conclusions For the first time in history will the IMIA Yearbook be published in an open access online format allowing a broader readership especially in resource poor countries. For the first time, thanks to the online format, will the IMIA Yearbook be published twice in the year, with two different tracks of papers. We anticipate that the important role of the IMIA yearbook will further increase with these changes just in time for its 25th anniversary in 2016. PMID:24853037

    Reductionist science produces causal models of small fragments of complicated systems. Causal models of entire systems can be hard to construct because what is known of them is distributed across a vast amount of literature. The Big Mechanism program aims to have machines read the literature and assemble the causal fragments found in individual papers into huge causal models, automatically. The current domain of the program is cell signalling associated with Ras-driven cancers. PMID:26178259

  19. The hot big bang and beyond

    NASA Astrophysics Data System (ADS)

    Turner, Michael S.

    1995-08-01

    The hot big-bang cosmology provides a reliable accounting of the Universe from about 10-2 sec after the bang until the present, as well as a robust framework for speculating back to times as early as 10-43 sec. Cosmology faces a number of important challenges; foremost among them are determining the quantity and composition of matter in the Universe and developing a detailed and coherent picture of how structure (galaxies, clusters of galaxies, superclusters, voids, great walls, and so on) developed. At present there is a working hypothesis-cold dark matter-which is based upon inflation and which, if correct, would extend the big bang model back to 10-32 sec and cast important light on the unification of the forces. Many experiments and observations, from CBR anisotropy experiments to Hubble Space Telescope observations to experiments at Fermilab and CERN, are now putting the cold dark matter theory to the test. At present it appears that the theory is viable only if the Hubble constant is smaller than current measurements indicate (around 30 km s-1 Mpc-1), or if the theory is modified slightly, e.g., by the addition of a cosmological constant, a small admixture of hot dark matter (5 eV ``worth of neutrinos''), more relativistic particle or a tilted spectrum of density perturbations.

    This series of Voyager 2 pictures of Tethys shows its distinctive large crater, 400 kilometers (250 miles) in diameter, as it rotates toward the termination and limb of this satellite of Saturn. These images were obtained at four-hour intervals beginning late Aug. 24 and ending early the next day; the distances were 1.1 million km. (670,000 mi.), 826,000 km. (510,000 mi.) and 680,000 km. (420,000 mi.), respectively. The crater, the remnant of a large impact, has a central peak and several concentric rings. Some grooves radiating from the center may be formed of material thrown from the crater during the impact. The bottom frame, with the crater in profile, reveals that its floor has risen back to the spherical shape of the satellite, unlike the large crater seen on Tethys sister moon Mimas. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.

    With a goal of producing faster, safer, and cheaper technologies for nuclear waste cleanup, Sandia is actively developing and extending intelligent systems technologies through the US Department of Energy Office of Technology Development (DOE OTD) Robotic Technology Development Program (RTDP). Graphical programming is a key technology for robotic waste cleanup that Sandia is developing for this goal. Graphical programming uses simulation such as TELEGRIP `on-line` to program and control robots. Characterized by its model-based control architecture, integrated simulation, `point-and-click` graphical user interfaces, task and path planning software, and network communications, Sandia`s Graphical Programming systems allow operators to focus on high-level robotic tasks rather than the low-level details. Use of scripted tasks, rather than customized programs minimizes the necessity of recompiling supervisory control systems and enhances flexibility. Rapid world-modelling technologies allow Graphical Programming to be used in dynamic and unpredictable environments including digging and pipe-cutting. This paper describes Sancho, Sandia`s most advanced graphical programming supervisory software. Sancho, now operational on several robot systems, incorporates all of Sandia`s recent advances in supervisory control. Graphical programming uses 3-D graphics models as intuitive operator interfaces to program and control complex robotic systems. The goal of the paper is to help the reader understand how Sandia implements graphical programming systems and which key features in Sancho have proven to be most effective.

  19. GFI - EASY PC GRAPHICS

    NASA Technical Reports Server (NTRS)

    Katz, R. B.

    1994-01-01

    Easy PC Graphics (GFI) is a graphical plot program that permits data to be easily and flexibly plotted. Data is input in a standard format which allows easy data entry and evaluation. Multiple dependent axes are also supported. The program may either be run in a stand alone mode or be embedded in the user's own software. Automatic scaling is built in for several logarithmic and decibel scales. New scales are easily incorporated into the code through the use of object-oriented programming techniques. For the autoscale routines and the actual plotting code, data is not retrieved directly from a file, but a "method" delivers the data, performing scaling as appropriate. Each object (variable) has state information which selects its own scaling. GFI is written in Turbo Pascal version 6.0 for IBM PC compatible computers running MS-DOS. The source code will only compile properly with the Turbo Pascal v. 6.0 or v. 7.0 compilers; however, an executable is provided on the distribution disk. This executable requires at least 64K of RAM and DOS 3.1 or higher, as well as an HP LaserJet printer to print output plots. The standard distribution medium for this program is one 5.25 inch 360K MS-DOS format diskette. The contents of the diskette are compressed using the PKWARE archiving tools. The utility to unarchive the files, PKUNZIP.EXE, is included. An electronic copy of the documentation is provided on the distribution medium in ASCII format. GFI was developed in 1993.

  20. LONGLIB - A GRAPHICS LIBRARY

    Long, D.

    1994-01-01

    This library is a set of subroutines designed for vector plotting to CRT's, plotters, dot matrix, and laser printers. LONGLIB subroutines are invoked by program calls similar to standard CALCOMP routines. In addition to the basic plotting routines, LONGLIB contains an extensive set of routines to allow viewport clipping, extended character sets, graphic input, shading, polar plots, and 3-D plotting with or without hidden line removal. LONGLIB capabilities include surface plots, contours, histograms, logarithm axes, world maps, and seismic plots. LONGLIB includes master subroutines, which are self-contained series of commonly used individual subroutines. When invoked, the master routine will initialize the plotting package, and will plot multiple curves, scatter plots, log plots, 3-D plots, etc. and then close the plot package, all with a single call. Supported devices include VT100 equipped with Selanar GR100 or GR100+ boards, VT125s, VT240s, VT220 equipped with Selanar SG220, Tektronix 4010/4014 or 4107/4109 and compatibles, and Graphon GO-235 terminals. Dot matrix printer output is available by using the provided raster scan conversion routines for DEC LA50, Printronix printers, and high or low resolution Trilog printers. Other output devices include QMS laser printers, Postscript compatible laser printers, and HPGL compatible plotters. The LONGLIB package includes the graphics library source code, an on-line help library, scan converter and meta file conversion programs, and command files for installing, creating, and testing the library. The latest version, 5.0, is significantly enhanced and has been made more portable. Also, the new version's meta file format has been changed and is incompatible with previous versions. A conversion utility is included to port the old meta files to the new format. Color terminal plotting has been incorporated. LONGLIB is written in FORTRAN 77 for batch or interactive execution and has been implemented on a DEC VAX series computer operating under VMS. This program was developed in 1985, and last updated in 1988.

  14. Big Bang, Blowup, and Modular Curves: Algebraic Geometry in Cosmology

    Yuri I. Manin; Matilde Marcolli

    2014-07-09

    We introduce some algebraic geometric models in cosmology related to the "boundaries" of space-time: Big Bang, Mixmaster Universe, Penrose's crossovers between aeons. We suggest to model the kinematics of Big Bang using the algebraic geometric (or analytic) blow up of a point $x$. This creates a boundary which consists of the projective space of tangent directions to $x$ and possibly of the light cone of $x$. We argue that time on the boundary undergoes the Wick rotation and becomes purely imaginary. The Mixmaster (Bianchi IX) model of the early history of the universe is neatly explained in this picture by postulating that the reverse Wick rotation follows a hyperbolic geodesic connecting imaginary time axis to the real one. Penrose's idea to see the Big Bang as a sign of crossover from "the end of previous aeon" of the expanding and cooling Universe to the "beginning of the next aeon" is interpreted as an identification of a natural boundary of Minkowski space at infinity with the Big Bang boundary.

  1. Big Box Reuse

    NSDL National Science Digital Library

    By now, the story is a familiar one, particularly for small towns and various exurban areas: A major retailer constructs what is referred to as a "big box" commercial building, and subsequently closes up shop several years later. While there is often a great public hue and cry over the construction of such buildings, few people have looked into what happens to these structures after they are abandoned. Julia Christensen (a MFA student at Rensselaer Polytechnic Institute) has stepped into the fray to help answer that question. With the use of an interactive map of the United States, visitors can view the transformation of such structures from major retail outlets into flea markets, churches, apartments, and a host of other uses. For each site, Christensen has also included photographs of how the building has been reused and adapted, adding a nice dimension to her work. Planners, architectural pundits, and others will find plenty to keep themselves busy within this intriguing site.

    Electroencephalography (EEG) is a novel modality for investigating perceptual graphics problems. Until recently, EEG has predominantly been used for clinical diagnosis, in psychology, and by the brain-computer-interface community. Researchers are extending it to help understand the perception of visual output from graphics applications and to create approaches based on direct neural feedback. Researchers have applied EEG to graphics to determine perceived image and video quality by detecting typical rendering artifacts, to evaluate visualization effectiveness by calculating the cognitive load, and to automatically optimize rendering parameters for images and videos on the basis of implicit neural feedback.

    We provide new behavioural norms for semantic classification of pictures and words. The picture stimuli are 288 black and white line drawings from the International Picture Naming Project ([Székely, A., Jacobsen, T., D'Amico, S., Devescovi, A., Andonova, E., Herron, D., et al. (2004). A new on-line resource for psycholinguistic studies. Journal of Memory & Language, 51, 247-250]). We presented these pictures for classification in a living/nonliving decision, and in a separate version of the task presented the corresponding word labels for classification. We analyzed behavioural responses to a subset of the stimuli in order to explore questions about semantic processing. We found multiple semantic richness effects for both picture and word classification. Further, while lexical-level factors were related to semantic classification of words, they were not related to semantic classification of pictures. We argue that these results are consistent with privileged semantic access for pictures, and point to ways in which these data could be used to address other questions about picture processing and semantic memory.

    In classical Laplacian image sharpening, all pixels are processed one by one, which leads to large amount of computation. Traditional Laplacian sharpening processed on CPU is considerably time-consuming especially for those large pictures. In this paper, we propose a parallel implementation of Laplacian sharpening based on Compute Unified Device Architecture (CUDA), which is a computing platform of Graphic Processing Units (GPU), and analyze the impact of picture size on performance and the relationship between the processing time of between data transfer time and parallel computing time. Further, according to different features of different memory, an improved scheme of our method is developed, which exploits shared memory in GPU instead of global memory and further increases the efficiency. Experimental results prove that two novel algorithms outperform traditional consequentially method based on OpenCV in the aspect of computing speed.

This belongs to a class of exact string backgrounds and is perturbative in the string coupling far away from the singularities, both of which can be resolved using matrix string theory. We provide a simple theory capable of describing the complete evolution of this closed universe.

    In this study, we report normative data by native Persian speakers for concept familiarity, age of acquisition (AoA), imageability, image agreement, name agreement, and visual complexity, as well as values for word frequency, word length, and naming latency for 200 of the colored Snodgrass and Vanderwart (Journal of Experimental Psychology: Human Learning and Memory 6:174-215, 1980) pictures created by Rossion and Pourtois (Perception 33:217-236, 2004). Using multiple regression analysis, we found independent effects of name agreement, image agreement, word frequency, and AoA on picture naming by native Persian speakers from Iran. We concluded that the psycholinguistic properties identified in studies of picture naming in many other languages also predict timed picture naming in Persian. Normative data for the ratings and picture-naming latencies for the 200 Persian object nouns are provided as an Excel file in the Supplemental materials. PMID:23292568

    Background Graphical displays of results allow researchers to summarise and communicate the key findings of their study. Diagnostic information should be presented in an easily interpretable way, which conveys both test characteristics (diagnostic accuracy) and the potential for use in clinical practice (predictive value). Methods We discuss the types of graphical display commonly encountered in primary diagnostic accuracy studies and systematic reviews of such studies, and systematically review the use of graphical displays in recent diagnostic primary studies and systematic reviews. Results We identified 57 primary studies and 49 systematic reviews. Fifty-six percent of primary studies and 53% of systematic reviews used graphical displays to present results. Dot-plot or box-and- whisker plots were the most commonly used graph in primary studies and were included in 22 (39%) studies. ROC plots were the most common type of plot included in systematic reviews and were included in 22 (45%) reviews. One primary study and five systematic reviews included a probability-modifying plot. Conclusion Graphical displays are currently underused in primary diagnostic accuracy studies and systematic reviews of such studies. Diagnostic accuracy studies need to include multiple types of graphic in order to provide both a detailed overview of the results (diagnostic accuracy) and to communicate information that can be used to inform clinical practice (predictive value). Work is required to improve graphical displays, to better communicate the utility of a test in clinical practice and the implications of test results for individual patients. PMID:18405357

    The basis for determining whether a printed piece is authentic requires a basic knowledge of the characteristics that distinguish one printing process from another and knowing when those processes would have been employed. Generally, no one who intends to counterfeit a printed piece, in order to make his efforts profitable, could use the same identical procedures and process as done with the original. It is almost impossible to perfectly replicate a printed piece wing to the fact that certain materials and tools used in the printing or graphic arts trades have had a limited existence. Knowing the historical background of these resources, understanding of the limitations of the craftsmen and the developments in the field over the last 50 to 60 years makes it possible for one to determine how and when something was printed. Some of these tools that were once almost exclusively sold to the trade ar now common household items. The age of low-cost home computers, computer printers and scanners has opened a whole new and lucrative market for those who see an opportunity to imitate the works of early craftsmen and artists, cashing in on the buyer's naivety.

    We investigate the way big rips are approached in a fully inhomogeneous description of the space-time geometry. If the pressure and energy densities are connected by a (supernegative) barotropic index, the spatial gradients and the anisotropic expansion decay as the big rip is approached. This behavior is contrasted with the usual big-bang singularities. A similar analysis is performed in the case of sudden (quiescent) singularities and it is argued that the spatial gradients may well be non-negligible in the vicinity of pressure singularities.

    2009-01-01

    Individuals with autism exhibit hypersensitivity to local elements of the input, which may interfere with the ability to group visual elements perceptually. We investigated the development of perceptual grouping abilities in high-functioning individuals with autism (HFA) across a wide age range (8–30 years) using a classic compound letter global/ local (GL) task and a more fine-grained microgenetic prime paradigm (MPP), including both few- and many-element hierarchical displays. In the GL task, contrary to the typically developing (TD) controls, HFA participants did not develop an increasing sensitivity to the global information with age. In the MPP, like the TD controls, individuals with autism at all three age groups evinced a bias to individuate the few-element displays. However, contrary to the TD controls, the HFA group failed to show age-related improvements in the ability to encode the global shape of the many-element displays. In fact, across the age range, the HFA group was consistently faster than the TD controls at perceiving the local elements in these displays. These results indicate that in autism the full process of garnering shape information from perceptual grouping, which is essential for the ability to do fast and efficient object recognition and identification, never matures, and this is especially evident in adolescence when this ability begins to improve in TD individuals. The atypical development of these perceptual organizational abilities may disrupt processing of visually presented objects, which may, in turn, fundamentally impede the development of major aspects of the social and emotional behaviors in individuals with autism.

    The safety profile of a drug evolves over its lifetime on the market; there are bound to be changes in the circumstances of a drug's clinical use which may give rise to previously unobserved adverse effects, hence necessitating surveillance postmarketing. Postmarketing surveillance has traditionally been carried out by systematic manual review of spontaneous reports of adverse drug reactions. Vast improvements in computing capabilities have provided opportunities to automate signal detection, and several worldwide initiatives are exploring new approaches to facilitate earlier detection, primarily through mining of routinely-collected data from electronic healthcare records (EHR). This paper provides an overview of ongoing initiatives exploring data from EHR for signal detection vis-à-vis established spontaneous reporting systems (SRS). We describe the role SRS has played in regulatory decision making with respect to safety issues, and evaluate the potential added value of EHR-based signal detection systems to the current practice of drug surveillance. Safety signal detection is both an iterative and dynamic process. It is in the best interest of public health to integrate and understand evidence from all possibly relevant information sources on drug safety. Proper evaluation and communication of potential signals identified remains an imperative and should accompany any signal detection activity. PMID:23377696

  7. Pictures open unexpected horizons in Nepal.

    PubMed

    Walker, D A

    1986-01-01

    Picture literacy constitutes one of the main accomplishments of Nepal's nonformal education program. Although program participants had little difficulty initially in identifying pictured objects, they were unable to understand the meaning or intended message of an illustration. In classroom discussions, participants were asked to analyze pictures, relate them to their own experiences, and read more meaning into illustrations. As the literacy curriculum was developed and tested, it became clear that the use of pictures greatly increased the number of meaningful ideas that could be communicated in the lessons. Comics were especially valuable in introducing social issues in a dramatic, exciting way that could not be achieved through stories with a limited vocabulary. While the written story must be coherent, the comic can be fragmentary and more ground can be covered. The pictures make the page less formidable and reinforce the written word. Once pictures and comics had been introduced into the literacy curriculum, experimentation with other uses was possible. For example, participants role-played the comics and created their own stories around discussion pictures. All these activities proved to be educationally sound and appropriate to the cultural setting. PMID:12314876

  8. Managing facts and concepts: computer graphics and information graphics from a graphic designer's perspective

    SciTech Connect

    Marcus, A.

    1983-01-01

    This book emphasizes the importance of graphic design for an information-oriented society. In an environment in which many new graphic communication technologies are emerging, it raises some issues which graphic designers and managers of graphic design production should consider in using the new technology effectively. In its final sections, it gives an example of the steps taken in designing a visual narrative as a prototype for responsible information-oriented graphic design. The management of complex facts and concepts, of complex systems of ideas and issues, presented in a visual as well as verbal narrative or dialogue and conveyed through new technology will challenge the graphic design community in the coming decades. This shift to visual-verbal communication has repercussions in the educational system and the political/governance systems that go beyond the scope of this book. If there is a single goal for this book, it is to stimulate the reader and then to provide references that will help you learn more about graphic design in an era of communication when know business is show business.

  9. Big climate data analysis

    NASA Astrophysics Data System (ADS)

    Mudelsee, Manfred

    2015-04-01

    The Big Data era has begun also in the climate sciences, not only in economics or molecular biology. We measure climate at increasing spatial resolution by means of satellites and look farther back in time at increasing temporal resolution by means of natural archives and proxy data. We use powerful supercomputers to run climate models. The model output of the calculations made for the IPCC's Fifth Assessment Report amounts to ~650 TB. The 'scientific evolution' of grid computing has started, and the 'scientific revolution' of quantum computing is being prepared. This will increase computing power, and data amount, by several orders of magnitude in the future. However, more data does not automatically mean more knowledge. We need statisticians, who are at the core of transforming data into knowledge. Statisticians notably also explore the limits of our knowledge (uncertainties, that is, confidence intervals and P-values). Mudelsee (2014 Climate Time Series Analysis: Classical Statistical and Bootstrap Methods. Second edition. Springer, Cham, xxxii + 454 pp.) coined the term 'optimal estimation'. Consider the hyperspace of climate estimation. It has many, but not infinite, dimensions. It consists of the three subspaces Monte Carlo design, method and measure. The Monte Carlo design describes the data generating process. The method subspace describes the estimation and confidence interval construction. The measure subspace describes how to detect the optimal estimation method for the Monte Carlo experiment. The envisaged large increase in computing power may bring the following idea of optimal climate estimation into existence. Given a data sample, some prior information (e.g. measurement standard errors) and a set of questions (parameters to be estimated), the first task is simple: perform an initial estimation on basis of existing knowledge and experience with such types of estimation problems. The second task requires the computing power: explore the hyperspace to find the suitable method, that is, the mode of estimation and uncertainty-measure determination that optimizes a selected measure for prescribed values close to the initial estimates. Also here, intelligent exploration methods (gradient, Brent, etc.) are useful. The third task is to apply the optimal estimation method to the climate dataset. This conference paper illustrates by means of three examples that optimal estimation has the potential to shape future big climate data analysis. First, we consider various hypothesis tests to study whether climate extremes are increasing in their occurrence. Second, we compare Pearson's and Spearman's correlation measures. Third, we introduce a novel estimator of the tail index, which helps to better quantify climate-change related risks.

Indeed, the BigBOSS project was recommended for substantial immediate R and D support the PASAG report. The second highest ground-based priority from the Astro2010 Decadal Survey was the creation of a funding line within the NSF to support a 'Mid-Scale Innovations' program, and it used BigBOSS as a 'compelling' example for support. This choice was the result of the Decadal Survey's Program Priorization panels reviewing 29 mid-scale projects and recommending BigBOSS 'very highly'.

    Big-bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time. We briefly overview the essentials of this physics, and present new calculations of light element abundances through li6 and li7, with updated nuclear reactions and uncertainties including those in the neutron lifetime. We provide fits to these results as a function of baryon density and of the number of neutrino flavors, N_nu. We review recent developments in BBN, particularly new, precision Planck cosmic microwave background (CMB) measurements that now probe the baryon density, helium content, and the effective number of degrees of freedom, n_eff. These measurements allow for a tight test of BBN and of cosmology using CMB data alone. Our likelihood analysis convolves the 2015 Planck data chains with our BBN output and observational data. Adding astronomical measurements of light elements strengthens the power of BBN. We include a ...

    1994-12-31

    As parallel programs enter the mainstream, they need to provide the same facilities and ease-of-use features expected of uniprocessor programs. For many applications, this means that they need to provide graphical output. This talk discusses a library of routines that provide scalable X Window System graphics. These routines make use of the MPI message-passing standard to provide a safe and reliable system that can be easily used in parallel programs. At the same time they encapsulate commonly-used services to provide a convenient interface to X graphics facilities. The easiest way to provide X11 graphics to a parallel program is to allow each process to draw on the same X11 Window. That is, each process opens a connection to the X11 server and draws directly to it. In one sense, this is as scalable a system as possible, since the single graphics display is an unavoidable point of sequential access. However, in reality, an X server can only accept a relatively small number of connections. In addition, the latency associated with each transmission between a parallel process and the X Window server is relatively high. This talk addresses these issues.

The activation was recorded from eight Dutch subjects with a whole-head neuromagnetometer. The processing model, based on extensive naming latency studies, is a stage model. In preparing a picture"s name, the speaker performs a chain of specific operations. They are, in this order, computing the visual percept, activating an appropriate lexical concept, selecting the target word from the mental lexicon, phonological encoding, phonetic encoding, and initiation of articulation. The time windows for each of these operations are reasonably well known and could be related to the peak activity of dipole sources in the individual magnetic response patterns. The analyses showed a clear progression over these time windows from early occipital activation, via parietal and temporal to frontal activation. The major specific findings were that (1) a region in the left posterior temporal lobe, agreeing with the location of Wernicke"s area, showed prominent activation starting about 200 msec after picture onset and peaking at about 350 msec (i.e., within the stage of phonological encoding), and (2) a consistent activation was found in the right parietal cortex, peaking at about 230 msec after picture onset, thus preceding and partly overlapping with the left temporal response. An interpretation in terms of the management of visual attention is proposed. PMID:9802989

    In the sector of Earth Observation, the explosion of data is due to many factors including: new satellite constellations, the increased capabilities of sensor technologies, social media, crowdsourcing, and the need for multidisciplinary and collaborative research to face Global Changes. In this area, there are many expectations and concerns about Big Data. Vendors have attempted to use this term for their commercial purposes. It is necessary to understand whether Big Data is a radical shift or an incremental change for the existing digital infrastructures. This presentation tries to explore and discuss the impact of Big Data challenges and new capabilities on the Global Earth Observation System of Systems (GEOSS) and particularly on its common digital infrastructure called GCI. GEOSS is a global and flexible network of content providers allowing decision makers to access an extraordinary range of data and information at their desk. The impact of the Big Data dimensionalities (commonly known as 'V' axes: volume, variety, velocity, veracity, visualization) on GEOSS is discussed. The main solutions and experimentation developed by GEOSS along these axes are introduced and analyzed. GEOSS is a pioneering framework for global and multidisciplinary data sharing in the Earth Observation realm; its experience on Big Data is valuable for the many lessons learned.

    We analyze the big bounce transition of the quantum FRW model in the setting of the nonstandard loop quantum cosmology (LQC). Elementary observables are used to quantize composite observables. The spectrum of the energy density operator is bounded and continuous. The spectrum of the volume operator is bounded from below and discrete. It has equally distant levels defining a quantum of the volume. The discreteness may imply a foamy structure of spacetime at semiclassical level which may be detected in astro-cosmo observations. The nonstandard LQC method has a free parameter that should be fixed in some way to specify the big bounce transition.

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by procedure of the double anaytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry. In the dual Yang-Mills theory description, these are non singular at all as the coupling goes to zero in the N=4 Super Yang-Mills theory. The cosmological singularities simply signal the failure of the supergravity description of the full type IIB superstring theory.

    With a goal of producing faster, safer, and cheaper technologies for nuclear waste cleanup, Sandia is actively developing and extending intelligent systems technologies. Graphical Programming is a key technology for robotic waste cleanup that Sandia is developing for this goal. This paper describes Sancho, Sandia most advanced Graphical Programming supervisory software. Sancho, now operational on several robot systems, incorporates all of Sandia`s recent advances in supervisory control. Sancho, developed to rapidly apply Graphical Programming on a diverse set of robot systems, uses a general set of tools to implement task and operational behavior. Sancho can be rapidly reconfigured for new tasks and operations without modifying the supervisory code. Other innovations include task-based interfaces, event-based sequencing, and sophisticated GUI design. These innovations have resulted in robot control programs and approaches that are easier and safer to use than teleoperation, off-line programming, or full automation.

  1. Structure and Dynamics of the Milky Way: The Evolving Picture

    NASA Astrophysics Data System (ADS)

    Foster, T.; Cooper, B.

    2010-12-01

    From the inception of radio astronomy, the study of the Interstellar Medium has been both aided and frustrated by one fact: we are right within it! Our embedded perspective is favourable to observing kinematic and structural details that are likely to remain inaccessible in external galaxies for some time, but not so to gaining a birds-eye view of our Galaxy's structure and motions on the largest scales. The Canadian Galactic Plane Survey (CGPS) is the original survey with the ability to image both details and the "big picture." We will broadly review what is known of the Milky Way, and focus on large-scale ISM structure and dynamics that the CGPS and immediate family of surveys depict particularly well (e.g. spiral structure, the rotation curve, density waves, rolling motions, the warp & scalloping). We also highlight areas where puzzles still exist (e.g. outer spiral structure, the question of shocks and rolling motions in the Milky Way), and offer some new insights (e.g. multiple shocks in the second quadrant; a radially varying spiral pattern speed in the disc) that demonstrate what is possible with current and future high-resolution 21 cm surveys.

  2. Superstring field theory in the democratic picture

    E-print Network

    Michael Kroyter

    2010-11-04

    We present a new open superstring field theory, whose string fields carry an arbitrary picture number and reside in the large Hilbert space. The redundancy related to picture number is resolved by treating picture changing as a gauge transformation. A mid-point insertion is imperative for this formalism. We find that this mid-point insertion must include all multi-picture changing operators. It is also proven that this insertion as well as all the multi-picture changing operators are zero weight conformal primaries. This new theory solves the problems with the Ramond sector shared by other RNS string field theories, while naturally unifying the NS and Ramond string fields. When partially gauge fixed, it reduces in the NS sector to the modified cubic superstring field theory. Hence, it shares all the good properties of this theory, e.g., it has analytical vacuum and marginal deformation solutions. Treating the redundant gauge symmetry using the BV formalism is straightforward and results in a cubic action with a single string field, whose quantum numbers are unconstrained. The generalization to an arbitrary brane system is simple and includes the standard Chan-Paton factors and the most general string field consistent with the brane system.

    Big MACS is a Python program that estimates an accurate photometric calibration from only an input catalog of stellar magnitudes and filter transmission functions. The user does not have to measure color terms which can be difficult to characterize. Supplied with filter transmission functions, Big MACS synthesizes an expected stellar locus for your data and then simultaneously solves for all unknown zeropoints when fitting to the instrumental locus. The code uses a spectroscopic model for the SDSS stellar locus in color-color space and filter functions to compute expected locus. The stellar locus model is corrected for Milky Way reddening. If SDSS or 2MASS photometry is available for stars in field, Big MACS can yield a highly accurate absolute calibration.

    The picture-worlds of children in the 21th century are not only evoked anymore by fairytales of the Brothers Grimm, but also by modern audio-visual stories (in books, comics, mangas, swap cards, films, videos and computer games). In psychological counselling and psychotherapy of children and adolescents we like to use such picture-worlds, modern myths and metaphors, to tie up with the experiences of the children and to kick start corresponding processes of maturation. Consultants can not only use their own treasures of myths remembering their own childhood (reading), but should also be familiar with the modern picture-worlds common to children in order to develop images which are shared by both counsellor and child, and should be capable of understanding the meaning of the characters and their actions. Some narratives and forms will be presented here in relation to developmental psychology. PMID:15543710

  12. Ubiquitous picture-rich content representation

    Wang, Wiley; Dean, Jennifer; Muzzolini, Russ

    2010-02-01

    The amount of digital images taken by the average consumer is consistently increasing. People enjoy the convenience of storing and sharing their pictures through online (digital) and offline (traditional) media. A set of pictures can be uploaded to: online photo services, web blogs and social network websites. Alternatively, these images can be used to generate: prints, cards, photo books or other photo products. Through uploading and sharing, images are easily transferred from one format to another. And often, a different set of associated content (text, tags) is created across formats. For example, on his web blog, a user may journal his experiences of his recent travel; on his social network website, his friends tag and comment on the pictures; in his online photo album, some pictures are titled and keyword-tagged. When the user wants to tell a complete story, perhaps in a photo book, he must collect, across all formats: the pictures, writings and comments, etc. and organize them in a book format. The user has to arrange the content of his trip in each format. The arrangement, the associations between the images, tags, keywords and text, cannot be shared with other formats. In this paper, we propose a system that allows the content to be easily created and shared across various digital media formats. We define a uniformed data association structure to connect: images, documents, comments, tags, keywords and other data. This content structure allows the user to switch representation formats without reediting. The framework under each format can emphasize (display or hide) content elements based on preference. For example, a slide show view will emphasize the display of pictures with limited text; a blog view will display highlighted images and journal text; and the photo book will try to fit in all images and text content. In this paper, we will discuss the strategy to associate pictures with text content, so that it can naturally tell a story. We will also list sample solutions on different formats such as: picture view, blog view and photo book view.

    We consider a picture in which the transition from a big crunch to a big bang corresponds to the collision of two empty orbifold planes approaching each other at a constant nonrelativistic speed in a locally flat background space-time, a situation relevant to recently proposed cosmological models. We show that p-brane states which wind around the extra dimension propagate smoothly and unambiguously across the orbifold plane collision. In particular we calculate the quantum mechanical production of winding M2-branes extending from one orbifold to the other. We find that the resulting density is finite and that the resulting gravitational backreaction is small. These winding states, which include the string theory graviton, can be propagated smoothly across the transition using a perturbative expansion in the membrane tension, an expansion which from the point of view of string theory is an expansion in inverse powers of {alpha}{sup '}. The conventional description of a crunch based on Einstein general relativity, involving Kasner or mixmaster behavior is misleading, we argue, because general relativity is only the leading order approximation to string theory in an expansion in positive powers of {alpha}{sup '}. In contrast, in the M theory setup we argue that interactions should be well behaved because of the smooth evolution of the fields combined with the fact that the string coupling tends to zero at the crunch. The production of massive Kaluza-Klein states should also be exponentially suppressed for small collision speeds. We contrast this good behavior with that found in previous studies of strings in Lorentzian orbifolds.

  14. Neural Correlates of Processing Negative and Sexually Arousing Pictures

    PubMed Central

    Bailey, Kira; West, Robert; Mullaney, Kellie M.

    2012-01-01

    Recent work has questioned whether the negativity bias is a distinct component of affective picture processing. The current study was designed to determine whether there are different neural correlates of processing positive and negative pictures using event-related brain potentials. The early posterior negativity and late positive potential were greatest in amplitude for erotic pictures. Partial Least Squares analysis revealed one latent variable that distinguished erotic pictures from neutral and positive pictures and another that differentiated negative pictures from neutral and positive pictures. The effects of orienting task on the neural correlates of processing negative and erotic pictures indicate that affective picture processing is sensitive to both stimulus-driven, and attentional or decision processes. The current data, together with other recent findings from our laboratory, lead to the suggestion that there are distinct neural correlates of processing negative and positive stimuli during affective picture processing.

    BigBOSS is a Stage IV ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and the growth of structure with a wide-area galaxy and quasar redshift survey over 14,000 square degrees. It has been conditionally accepted by NOAO in response to a call for major new instrumentation and a high-impact science program for the 4-m Mayall telescope at Kitt Peak. The BigBOSS instrument is a robotically-actuated, fiber-fed spectrograph capable of taking 5000 simultaneous spectra over a wavelength range from 340 nm to 1060 nm, with a resolution R = {lambda}/{Delta}{lambda} = 3000-4800. Using data from imaging surveys that are already underway, spectroscopic targets are selected that trace the underlying dark matter distribution. In particular, targets include luminous red galaxies (LRGs) up to z = 1.0, extending the BOSS LRG survey in both redshift and survey area. To probe the universe out to even higher redshift, BigBOSS will target bright [OII] emission line galaxies (ELGs) up to z = 1.7. In total, 20 million galaxy redshifts are obtained to measure the BAO feature, trace the matter power spectrum at smaller scales, and detect redshift space distortions. BigBOSS will provide additional constraints on early dark energy and on the curvature of the universe by measuring the Ly-alpha forest in the spectra of over 600,000 2.2 < z < 3.5 quasars. BigBOSS galaxy BAO measurements combined with an analysis of the broadband power, including the Ly-alpha forest in BigBOSS quasar spectra, achieves a FOM of 395 with Planck plus Stage III priors. This FOM is based on conservative assumptions for the analysis of broad band power (k{sub max} = 0.15), and could grow to over 600 if current work allows us to push the analysis to higher wave numbers (k{sub max} = 0.3). BigBOSS will also place constraints on theories of modified gravity and inflation, and will measure the sum of neutrino masses to 0.024 eV accuracy.
