    Urrea, Claudia

    2010-01-01

    A one-to-one learning environment, where each participating student and the teacher use a laptop computer, provides an invaluable opportunity for rethinking learning and studying the ways in which children can program computers and learn to think about their own thinking styles and become epistemologists. This article presents a study done in a rural school in Costa Rica in which students used computers to create media. Three important components of the work are described: (1) student-owned technology that can accompany students as they interact at home and in the broader community, (2) activities that are designed with sufficient scope to encourage the appropriation of powerful ideas, and (3) teacher engagement in activity design with simultaneous support from a knowledge network of local and international colleagues and mentors.

    1978-01-01

    The woman pictured below is sitting down to a nutritious, easily-prepared meal similar to those consumed by Apollo astronauts. The appetizing dishes shown were created simply by adding water to the contents of a Mountain House* Easy Meal package of freeze dried food. The Easy Meal line is produced by Oregon Freeze Dry Foods, Inc., Albany, Oreaon, a pioneer in freeze drying technology and a company long associated with NASA in developing suitable preparations for use on manned spacecraft. Designed to provide nutritionally balanced, attractive hot meals for senior adults, Easy Meal is an offshoot of a 1975-77 demonstration project managed by Johnson Space Center and called Meal System for the Elderly. The project sought ways to help the estimated 3.5 million elderly Americans who are unable to take advantage of existing meal programs. Such services are provided by federal, state and local agencies, but they are not available to many who live in rural areas, or others who are handicapped, temporarily ill or homebound for other reasons. Oregon Freeze Dry Foods was a participant in that multi-agency cooperative project. With its Easy Meal assortment of convenience foods pictured above left, the company is making commercially available meal packages similar to those distributed in the Meal System for the Elderly program. In the freeze drying process, water is extracted from freshly-cooked foods by dehydration at very low temperatures, as low as 50 I degrees below zero. Flavor is locked in by packaging the dried food in pouches which block out moisture and oxygen, the principal causes of food deterioration; thus the food can be stored for long periods without refrigeration. Meals are reconstituted by adding hot or cold water, depending on the type of food, and they are table ready in five to 10 minutes. Oregon Freeze Dry Foods offers five different meal packages and plans to expand the line.

    2009-05-27

    Outsider Art (art brut) is defined as a mode of original artistic expression which thrives on its independence, shunning the public sphere and the art market. Such art can be highly idiosyncratic and secretive, and reflects the individual creator's attempt to construct a coherent, albeit strange, private world. Certain practitioners of what may be termed autistic art are examined in the light of this definition; their work is considered as evidence not of a medical condition but of an expressive intentionality entirely worthy of the interest of those drawn to the aesthetic experience.

  10. 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.

  11. Growth rates made easy.

    PubMed

    Hall, Barry G; Acar, Hande; Nandipati, Anna; Barlow, Miriam

    2014-01-01

    In the 1960s-1980s, determination of bacterial growth rates was an important tool in microbial genetics, biochemistry, molecular biology, and microbial physiology. The exciting technical developments of the 1990s and the 2000s eclipsed that tool; as a result, many investigators today lack experience with growth rate measurements. Recently, investigators in a number of areas have started to use measurements of bacterial growth rates for a variety of purposes. Those measurements have been greatly facilitated by the availability of microwell plate readers that permit the simultaneous measurements on up to 384 different cultures. Only the exponential (logarithmic) portions of the resulting growth curves are useful for determining growth rates, and manual determination of that portion and calculation of growth rates can be tedious for high-throughput purposes. Here, we introduce the program GrowthRates that uses plate reader output files to automatically determine the exponential portion of the curve and to automatically calculate the growth rate, the maximum culture density, and the duration of the growth lag phase. GrowthRates is freely available for Macintosh, Windows, and Linux. We discuss the effects of culture volume, the classical bacterial growth curve, and the differences between determinations in rich media and minimal (mineral salts) media. This protocol covers calibration of the plate reader, growth of culture inocula for both rich and minimal media, and experimental setup. As a guide to reliability, we report typical day-to-day variation in growth rates and variation within experiments with respect to position of wells within the plates.

  12. The Creator of Astrobotany, Gavriil Adrianovich Tikhov

    NASA Astrophysics Data System (ADS)

    Briot, Danielle

    The Russian astronomer, Gavriil Adrianovich Tikhov (1875-1960), was one of the main pioneers of astrobiology and was the creator of astrobotany. From 1906 to 1941, he began his career as an astronomer in the Pulkovo Observatory, near Saint Petersburg, and then moved to Alma-Ata (Kazakhstan) until the end of his life. He specialized in many different fields of astronomy: besides astrobotany and astrobiology, he studied the Sun, the planets, the comets, the blue color and polarization of the sky, the Earthshine, variable stars, as well as interstellar absorption. He designed new instruments and wrote more than 230 scientific papers. As early as 1914, on the basis of observations of Earthshine, he concluded that Earth seen from space has to be seen with a pale blue color. Tikhov's main research was focused on the search for extraterrestrial life, particularly the presence of vegetation on Mars. At this time, many astronomers believed in the existence of canals on the Martian surface. Seasonal variations of color on the surface of Mars were often interpreted as changes of vegetation, as on Earth. From 1909, he observed Mars during favorable configurations, that is to say Mars oppositions, first using filters and then with a spectrograph. However, he failed to detect chlorophyll in Mars' spectra. So he decided to go looking for plants with no chlorophyll, especially plants growing in extreme environments like on Mars and to study and measure their reflectance spectrum. Tikhov, who was one of the first scientists to use the word "astrobiology," coined the word "astrobotany" in 1945. In 1947 he founded a Department of Astrobotany at Alma-Ata Observatory, where students, biologists, botanists, and physicists joined to study the reflectance spectra of plants growing in conditions similar to those found on Mars. Expeditions were organized in very cold or very dry places with this aim in view. After he died, the Department of Astrobotany was dismantled. After nearly half a

  15. Easy Volcanic Aerosol

    NASA Astrophysics Data System (ADS)

    Toohey, Matthew; Stevens, Bjorn; Schmidt, Hauke; Timmreck, Claudia

    2016-04-01

    Radiative forcing by stratospheric sulfate aerosol of volcanic origin is one of the strongest drivers of natural climate variability. Transient model simulations attempting to match observed climate variability, such as the CMIP historical simulations, rely on volcanic forcing reconstructions based on observations of a small sample of recent eruptions and coarse proxy data for eruptions before the satellite era. Volcanic forcing data sets used in CMIP5 were provided either in terms of optical properties, or in terms of sulfate aerosol mass, leading to significant inter-model spread in the actual volcanic radiative forcing produced by models and in their resulting climate responses. It remains therefore unclear to what degree inter-model spread in response to volcanic forcing represents model differences or variations in the forcing. In order to isolate model differences, Easy Volcanic Aerosol (EVA) provides an analytic representation of volcanic stratospheric aerosol forcing, based on available observations and aerosol model results, prescribing the aerosol's radiative properties and primary modes of spatial and temporal variability. In contrast to regriddings of observational data, EVA allows for the production of physically consistent forcing for historic and hypothetical eruptions of varying magnitude, source latitude, and season. Within CMIP6, EVA will be used to reconstruct volcanic forcing over the past 2000 years for use in the Paleo-Modeling Intercomparison Project (PMIP), and will provide forcing sets for VolMIP experiments aiming to quantify model uncertainty in the response to volcanic forcing. Here, the functional form of EVA will be introduced, along with illustrative examples including the EVA-based reconstruction of volcanic forcing over the historical period, and that of the 1815 Tambora eruption.

    1999-04-01

    Easy-to-use interfaces are a class of interfaces that fall between public access interfaces and graphical user interfaces in usability and cognitive difficulty. We describe characteristics of easy-to-use interfaces by the properties of four dimensions: selection, navigation, direct manipulation, and contextual metaphors. Another constraint we introduced was to include as little text as possible, and what text we have will be in at least four languages. Formative evaluations were conducted to identify and isolate these characteristics. Our application is a visual interface for a home automation system intended for a diverse set of users. The design will be expanded to accommodate the visually disabled in the near future.

  20. Creators' intentions bias judgments of function independently from causal inferences.

    PubMed

    Chaigneau, Sergio E; Castillo, Ramón D; Martínez, Luis

    2008-10-01

    Participants learned about novel artifacts that were created for function X, but later used for function Y. When asked to rate the extent to which X and Y were a given artifact's function, participants consistently rated X higher than Y. In Experiments 1 and 2, participants were also asked to rate artifacts' efficiency to perform X and Y. This allowed us to test if participants' preference for X was mediated by causal inferences. Experiment 1 showed that participants did not infer intentionally created artifacts performed X more efficiently than Y. Experiment 2 showed participants did not infer that only an efficient (but not an inefficient) artifact provided evidence of intentional creation. Causal inferences involving efficiency, did not account for participants' preferences. In Experiment 3, in contrast, when the creator changed her mind about an artifact's function (i.e., from X to Y), the preference for the original function tended to disappear. Creators' intentions were the basis for participants' preference. Results are discussed relative to essentialist theories.

  4. EASI - EQUILIBRIUM AIR SHOCK INTERFERENCE

    NASA Technical Reports Server (NTRS)

    Glass, C. E.

    1994-01-01

    New research on hypersonic vehicles, such as the National Aero-Space Plane (NASP), has raised concerns about the effects of shock-wave interference on various structural components of the craft. State-of-the-art aerothermal analysis software is inadequate to predict local flow and heat flux in areas of extremely high heat transfer, such as the surface impingement of an Edney-type supersonic jet. EASI revives and updates older computational methods for calculating inviscid flow field and maximum heating from shock wave interference. The program expands these methods to solve problems involving the six shock-wave interference patterns on a two-dimensional cylindrical leading edge with an equilibrium chemically reacting gas mixture (representing, for example, the scramjet cowl of the NASP). The inclusion of gas chemistry allows for a more accurate prediction of the maximum pressure and heating loads by accounting for the effects of high temperature on the air mixture. Caloric imperfections and specie dissociation of high-temperature air cause shock-wave angles, flow deflection angles, and thermodynamic properties to differ from those calculated by a calorically perfect gas model. EASI contains pressure- and temperature-dependent thermodynamic and transport properties to determine heating rates, and uses either a calorically perfect air model or an 11-specie, 7-reaction reacting air model at equilibrium with temperatures up to 15,000 K for the inviscid flowfield calculations. EASI solves the flow field and the associated maximum surface pressure and heat flux for the six common types of shock wave interference. Depending on the type of interference, the program solves for shock-wave/boundary-layer interaction, expansion-fan/boundary-layer interaction, attaching shear layer or supersonic jet impingement. Heat flux predictions require a knowledge (from experimental data or relevant calculations) of a pertinent length scale of the interaction. Output files contain flow

    TrishearCreator is a platform independent web program constructed in Flash, which enables fold modeling, numerical simulation of trishear fault-propagation folding and strain analysis, etc. In the program, various types of original strata, such as folds and inclined strata can be easily constructed via adjusting shape parameters. In the simulation of trishear fault-propagation folding, growth strata and strain ellipses are calculated and displayed simultaneously. This web-based program is easy to use. Model parameters are changed by simple mouse actions, which have the advantage of speed and simplicity. And it gives an instant visual appreciation of the effect of changing the parameters that are used to construct the initial configuration of the model and the fold-propagation folding. These data can be exported to a text file, and be shared with other geologists to replay the kinematic evolution of structures using the program.

    An ambient ionization/desorption technique, namely, easy ambient sonic-spray ionization mass spectrometry (EASI), has been applied to crude oil samples. From a single droplet of the sample placed on an inert surface, EASI(+/-) is shown to promote efficient desorption and ionization of a myriad of polar components via the action of its cloud of very minute supersonic bipolar charged droplets. The gaseous [M + H](+) and [M - H](-) ions concurrently formed by EASI(+/-) were analyzed by Fourier transform mass spectrometry (FT-ICR MS), and a total of approximately 6000 acidic and basic components have been attributed. EASI(+/-) FT-ICR MS of crude oils is show to be almost as fast as ESI(+)/ESI(-) FT-ICR MS, providing similar compositional information of polar components and spectral quality comparable to that of a commercial nonochip-based robotic ESI device. EASI(+/-) requires no sample workup thus eliminating risks of contamination during sample manipulation and memory effects because of carry over in pumping ESI lines. More importantly, EASI(+/-) is a voltage-free ionization technique therefore eliminating risks of redox processes or duality of ionization mechanisms that can be observed in voltage-assisted processes. Data visualization via typical petroleomic plots confirms the similarity of the compositional information provided by EASI(+/-) compared to ESI(+)/ESI(-). The ambient EASI(+/-) FT-ICR MS method requires no voltage switching in changing the ion polarity mode, offering a workup, heating and voltage-free protocol for petroleomic studies performed at open atmosphere directly on the undisturbed crude oil sample.

  14. Ensuring Credit to Data Creators: A Case Study for Geodesy

    NASA Astrophysics Data System (ADS)

    2011-12-01

    facilitate citation for the purpose of ensuring credit to the data creators. UNAVCO's archiving and metadata management systems are generally well-suited to assigning and maintaining DOIs for two styles of logical collections of data: campaigns, which are spatially and temporally well-defined; and stations, which represent ongoing collection at a single spatial position at the Earth's surface. These two styles form the basis for implementing approximately 3,000 DOIs that can encompass the current holdings in the UNAVCO Archive. In addition, aggregations of DOIs into a superset DOI is advantageous for numerous cases where groupings of stations are naturally used in research studies. There are about 100 such natural collections of stations. However, research using GNSS data can also utilize several hundred or more stations in unique combinations, where tallying the individual DOIs within a reference list is cumbersome. We are grappling with the complexities that inevitably crop up when assigning DOIs, including subsetting, versioning, and aggregating. We also foresee the need for mechanisms for users to go beyond our predefined collections and/or aggregations to define their own ad-hoc collections. Our goal is to create a system for DOI assignment and utilization that succeeds in facilitating data citation within our community of geodesy scientists.

    To become full and active participants in today's technologically saturated society, young people need to become creators (and not just consumers) of interactive media. Developing the requisite abilities and capacities is not a wholly individual process; it is important for young people to have access to communities where they can collaborate and share ideas. This article uses the Scratch online community for exploring how different forms of participation and collaboration can support and shape the ways in which young people develop as creators of interactive media. We describe participation in this community in terms of a spectrum ranging from socializing to creating and present examples of three forms of collaboration within the community. We argue that the most exciting interactive media creation and valuable learning experiences are taking place in the middle space, where participants draw on the best of socializing and creating practices.

    This article presents a Web-based tool for the creation of divergent-thinking and open-ended creativity tasks. A Java program generates HTML forms with PHP scripting that run an Alternate Uses Task and/or open-ended response items. Researchers may specify their own instructions, objects, and time limits, or use default settings. Participants can also be prompted to select their best responses to the Alternate Uses Task (Silvia et al., 2008). Minimal programming knowledge is required. The program runs on any server, and responses are recorded in a standard MySQL database. Responses can be scored using the consensual assessment technique (Amabile, 1996) or Torrance's (1998) traditional scoring method. Adoption of this Web-based tool should facilitate creativity research across cultures and access to eminent creators. The Creative Task Creator may be downloaded from the Psychonomic Society's Archive of Norms, Stimuli, and Data, www.psychonomic.org/archive.

    Chertkov, Michael; Chernyak, Vladimir

    2009-01-01

    We describe a rich family of binary variables statistical mechanics models on planar graphs which are equivalent to Gaussian Grassmann Graphical models (free fermions). Calculation of partition function (weighted counting) in the models is easy (of polynomial complexity) as reduced to evaluation of determinants of matrixes linear in the number of variables. In particular, this family of models covers Holographic Algorithms of Valiant and extends on the Gauge Transformations discussed in our previous works.

    To measure the quantum correlation of a bipartite state, a test matrix is constructed through the commutations among the blocks of its density matrix, which turns out to be a zero matrix for a classical state with zero quantum correlation, and a nonzero one for a quantum state with positive quantum correlation. The Frobenius norm of the test matrix is used to measure the quantum correlation, which satisfies the basic requirements for a good measure and coincides with Wootters concurrence for two-qubit pure states. Since no optimization is involved in the definition, this measure of quantum correlation is easy to compute and even can be calculated manually.

    We describe a rich family of binary variables statistical mechanics models on a given planar graph which are equivalent to Gaussian Grassmann graphical models (free fermions) defined on the same graph. Calculation of the partition function (weighted counting) for such a model is easy (of polynomial complexity) as it is reducible to evaluation of a Pfaffian of a matrix of size equal to twice the number of edges in the graph. In particular, this approach touches upon holographic algorithms of Valiant and utilizes the gauge transformations discussed in our previous works.

    1991-09-01

    Although many automated tools support the productivity of professionals (engineers, managers, architects, secretaries, etc.), none specifically address the needs of the scientific researcher. The scientist's needs are complex and the primary activities are cognitive rather than physical. The individual scientist collects and manipulates large data sets, integrates, synthesizes, generates, and records information. The means to access and manipulate information are a critical determinant of the performance of the system as a whole. One hindrance in this process is the scientist's computer environment, which has changed little in the last two decades. Extensive time and effort is demanded from the scientist to learn to use the computer system. This paper describes how chemists' activities and interactions with information were abstracted into a common paradigm that meets the critical requirement of facilitating information access and retrieval. This paradigm was embodied in EASI, a working prototype that increased the productivity of the individual scientific researcher. 4 refs., 2 figs., 1 tab.

    1998-03-01

    Object-based media refers to the representation of audiovisual information as a collection of objects - the result of scene-analysis algorithms - and a script describing how they are to be rendered for display. Such multimedia presentations can adapt to viewing circumstances as well as to viewer preferences and behavior, and can provide a richer link between content creator and consumer. With faster networks and processors, such ideas become applicable to live interpersonal communications as well, creating a more natural and productive alternative to traditional videoconferencing. In this paper is outlined an example of object-based media algorithms and applications developed by my group, and present new hardware architectures and software methods that we have developed to enable meeting the computational requirements of object- based and other advanced media representations. In particular we describe stream-based processing, which enables automatic run-time parallelization of multidimensional signal processing tasks even given heterogenous computational resources.

  9. Easy system call tracing for Plan 9.

    SciTech Connect

    Minnich, Ronald G.

    2010-09-01

    Tracing system calls makes debugging easy and fast. On Plan 9, traditionally, system call tracing has been implemented with acid. New systems do not always implement all the capabilities needed for Acid, particularly the ability to rewrite the process code space to insert breakpoints. Architecture support libraries are not always available for Acid, or may not work even on a supported architecture. The requirement that Acid's libraries be available can be a problem on systems with a very small memory footprint, such as High Performance Computing systems where every Kbyte counts. Finally, Acid tracing is inconvenient in the presence of forks, which means tracing shell pipelines is particularly troublesome. The strace program available on most Unix systems is far more convenient to use and more capable than Acid for system call tracing. A similar system on Plan 9 can simplify troubleshooting. We have built a system calling tracing capability into the Plan 9 kernel. It has proven to be more convenient than strace in programming effort. One can write a shell script to implement tracing, and the C code to implement an strace equivalent is several orders of magnitude smaller.

  10. Visualization of Large Terrains Made Easy

    Lindstrom, P; Pascucci, V

    2001-08-07

    We present an elegant and simple to implement framework for performing out-of-core visualization and view-dependent refinement of large terrain surfaces. Contrary to the recent trend of increasingly elaborate algorithms for large-scale terrain visualization, our algorithms and data structures have been designed with the primary goal of simplicity and efficiency of implementation. Our approach to managing large terrain data also departs from more conventional strategies based on data tiling. Rather than emphasizing how to segment and efficiently bring data in and out of memory, we focus on the manner in which the data is laid out to achieve good memory coherency for data accesses made in a top-down (coarse-to-fine) refinement of the terrain. We present and compare the results of using several different data indexing schemes, and propose a simple to compute index that yields substantial improvements in locality and speed over more commonly used data layouts. Our second contribution is a new and simple, yet easy to generalize method for view-dependent refinement. Similar to several published methods in this area, we use longest edge bisection in a top-down traversal of the mesh hierarchy to produce a continuous surface with subdivision connectivity. In tandem with the refinement, we perform view frustum culling and triangle stripping. These three components are done together in a single pass over the mesh. We show how this framework supports virtually any error metric, while still being highly memory and compute efficient.

    2013-12-01

    At 2011 we have described the imbalance of water in Nature as the system [1]. At 2012 we have described water and carbon and the glaciers [2], [3] as creators of the imbalance of Nature. Now we are describing some man-made creators of the imbalance of Nature. The photosynthesis is a powerful creator of the imbalance of Nature. The photosynthesis significantly increases the complexity of the structures and reduces the entropy. Earth's hydrosphere contains water less than it was flowed via photosynthesis. This is an example of the imbalance of involving when the return of water has delayed because water is involved into the processes of life and other processes. People widely use photosynthesis and create not only an additional man-made imbalance of water in Nature, but also the man-made changing the albedo, and a lot of other important parameters of the planet of Earth. All of these processes are significantly imbalanced. The fossil hydrocarbons have accumulated during millions of years, but now are burned. This is an example of the imbalance delay by time. The man-made burning of the hydrocarbons is creating the imbalances of impact or explosive type, because of the burning processes is in millions of times faster than the accumulation processes. Please pay attention to the imbalance of redeployment by places. For example, oil and gas are extracted in one places, and burned in others. During combustion is standing out not only water, but energy, and other components. The temperature in the centers of big cities is always higher and there is dominating the rising air. It pollutes the environment, changes circulations, create greenhouse effect, etc. Other examples of the imbalance of relocation are shown in the production and consumption of food. The irrigation systems transfer water from one place to another. This transfer of water creates a lot of imbalances in change climate, ecosystems, etc in places where water was took and where the water was brought. Usually

  15. EZID: Long term identifiers made easy (Invited)

    NASA Astrophysics Data System (ADS)

    Starr, J.

    2013-12-01

    Scholarly research is producing ever increasing amounts of digital research data, and this data should be managed throughout the research life cycle both as part of good scientific practice, but also to comply with funder mandates, such as the 2013 OSTP Public Access Memo (http://www.whitehouse.gov/sites/default/files/microsites/ostp/ostp_public_access_memo_2013.pdf). By assigning unique and persistent identifiers to data objects, data managers can gain control and flexibility over what can be a daunting task. This is due to the fact that the objects can be moved to new locations without disruption to links, as long as the identifier target is maintained. EZID is a tool that makes assigning and maintaining unique, persistent identifiers easy. It was designed and built by California Digital Library (CDL) and has both a user interface and a RESTful API. EZID currently offers services for two globally unique, persistent identifier schemes: Digital Object Identifiers (DOIs) and Archival Resource Keys (ARKs). DOIs are identifiers originating from the publishing world and are in widespread use for journal articles. CDL is able to offer DOIs because of being a founding member of DataCite (http://www.datacite.org/), an international consortium established to provide easier access to scientific research data on the Internet. ARKs are identifiers originating from the library, archive and museum community. Like DOIs, they become persistent when the objects and identifier forwarding information is maintained. DOIs and ARKs have a key role in data management and, therefore, in data management plans. DOIs are the recommended identifier for use in data citation, and ARKs provide the maximum flexibility needed for data documentation and management throughout the early phases of a project. The two identifier schemes are able to be used together, and EZID is made to work with both. EZID clients, coming from education, research, government, and the private sector, are utilizing the

    A promoter vector pACPR33 for Escherichia coli based on the promotorless ampicillin-resistance gene from pBR322 has been constructed. The promoter of the ampicillin-resistance gene was deleted and replaced by a suitable multiple cloning site. Molecular cloning of promoters into the polylinker resulted in activation of the ampicillin resistance in E. coli. The plasmid contains a functional origin of DNA replication and a tetracycline resistance gene for E. coli, and a chloramphenicol resistance gene for S. aureus. The vector permitted direct detection of promoter activity, especially strong promoters, by easy iodometric determination of beta-lactamase activity in liquid or solid media.

    The "TimeScale Creator" team (www.tscreator.org) and the Subcommission on Stratigraphic Information (stratigraphy.science.purdue.edu) of the International Commission on Stratigraphy (www.stratigraphy.org) has worked with numerous geoscientists and geological surveys to prepare reference datasets for global and regional stratigraphy. All events are currently calibrated to Geologic Time Scale 2004 (Gradstein et al., 2004, Cambridge Univ. Press) and Concise Geologic Time Scale (Ogg et al., 2008, Cambridge Univ. Press); but the array of intercalibrations enable dynamic adjustment to future numerical age scales and interpolation methods. The main "global" database contains over 25,000 events/zones from paleontology, geomagnetics, sea-level and sequence stratigraphy, igneous provinces, bolide impacts, plus several stable isotope curves and image sets. Several regional datasets are provided in conjunction with geological surveys, with numerical ages interpolated using a similar flexible inter-calibration procedure. For example, a joint program with Geoscience Australia has compiled an extensive Australian regional biostratigraphy and a full array of basin lithologic columns with each formation linked to public lexicons of all Proterozoic through Phanerozoic basins - nearly 500 columns of over 9,000 data lines plus hot-curser links to oil-gas reference wells. Other datapacks include New Zealand biostratigraphy and basin transects (ca. 200 columns), Russian biostratigraphy, British Isles regional stratigraphy, Gulf of Mexico biostratigraphy and lithostratigraphy, high-resolution Neogene stable isotope curves and ice-core data, human cultural episodes, and Circum-Arctic stratigraphy sets. The growing library of datasets is designed for viewing and chart-making in the free "TimeScale Creator" JAVA package.

    Open Display Networks have the potential to allow many content creators to publish their media to an open-ended set of screen displays. However, this raises the issue of how to match that content to the right displays. In this study, we aim to understand how the perceived utility of particular media sharing scenarios is affected by three independent variables, more specifically: (a) the locativeness of the content being shared; (b) how personal that content is and (c) the scope in which it is being shared. To assess these effects, we composed a set of 24 media sharing scenarios embedded with different treatments of our three independent variables. We then asked 100 participants to express their perception of the relevance of those scenarios. The results suggest a clear preference for scenarios where content is both local and directly related to the person that is publishing it. This is in stark contrast to the types of content that are commonly found in public displays, and confirms the opportunity that open displays networks may represent a new media for self-expression. This novel understanding may inform the design of new publication paradigms that will enable people to share media across the display networks.

    1999-08-01

    Oil and gas pipelines are generally magnetically anisotropic, with a magnetic easy axis in the pipe axial direction. This is of interest because magnetic flux leakage tools are commonly used for the detection and sizing of defects. In the present study we investigate the origin of this magnetic easy axis, using an angular magnetic Barkhausen noise technique to characterize the magnetic anisotropy. The texture, microstructure, and residual stress are examined as possible causes of the easy axis, using x-ray pole figure analysis and microstructural examination along with high and low temperature annealing treatments. Our results indicate that plastic deformation and residual stress are responsible for the magnetic easy axis, since an elimination of the residual stresses through low temperature "stress relief" heat treatment produces a magnetically isotropic structure without altering the texture or microstructure. X-ray pole figure analysis supports the conclusion that magnetic anisotropy is not related to texture in these materials. We conclude that the axial magnetic easy axis is due to a compressive residual hoop stress resulting from the cold bending and cold expansion of the pipe during processing.

    NASA Astrophysics Data System (ADS)

    Pan, Zhigeng; Huang, Jin; Xu, Weiwei; Zhou, Kun; Shi, Jiaoying

    2003-04-01

    In this paper we describe a virtual bowling game machine called EasyBowling Machine, which is designed and implemented based on techniques such as Virtual Reality, animation, and image processing. To introduce Virtual Reality technique into this virtual bowling game, our system provides a real game mode: players play the game by throwing a real bowling ball, and then the EasyBowling system uses a PC Camera to detect the motion of the real bowling ball. After the motion parameters (ball direction, ball force, et al.) are computed, the movement of the bowling ball and its collision with pins are simulated on a large display screen. The most obvious advantage of such bowling game machine over other existing bowling games is that the system integrates body exercise into game playing. The implementation techniques are discussed in detail, and the prototype system illustrates the feasibility and efficiency of our method.

    We consider a model of the aftereffect where the walls are detached from pin defects by vibrations. Dependence is obtained between the activation energy on the external field which is used to estimate the distance between defects, the radius of pin cavity and the stability time in a real film. The calculation is restricted to limp domain walls and ultrathin films with easy perpendicular direction. The model is tested to compare experimental data of the coercive force with a calculated value.

    2004-05-01

    Mine detection is to date mainly performed with metal detectors, although new methods for UXO detection are explored worldwide. The main problem for the mine detection to date is, that there exist some ideas of which sensor combinations could yield a high score, but until now there is no systematic analysis of mine detection methods together with realistic environmental conditions to conclude on a physically and technically optimized sensor combination. This gap will be removed by a project "easyMine" (Realistic and systematic Mine Detection Simulation Tool) which will result in a simulation tool for optimizing land mine detection in a realistic mine field. The project idea for this software tool is presented, that will simulate the closed chain of mine detection, including the mine in its natural environment, the sensor, the evaluation and application of the measurements by an user. The tool will be modularly designed. Each chain link will be an independent, exchangeable sub- module and will describe a stand alone part of the whole mine detection procedure. The advantage of the tool will be the evaluation of very different kinds of sensor combinations in relation of their real potential for mine detection. Three detection methods (metal detector, GPR and imaging IR-radiometry) will be explained to be introduced into the easyMine software tool in a first step. An actual example for land mine detection problem will be presented and approaches for solutions with easyMine will be shown.

    Otitis media (OM) or middle ear inflammation is a spectrum of diseases, including acute otitis media (AOM), otitis media with effusion (OME; 'glue ear') and chronic suppurative otitis media (CSOM). OM is among the most common diseases in young children worldwide. Although OM may resolve spontaneously without complications, it can be associated with hearing loss and life-long sequelae. In developing countries, CSOM is a leading cause of hearing loss. OM can be of bacterial or viral origin; during 'colds', viruses can ascend through the Eustachian tube to the middle ear and pave the way for bacterial otopathogens that reside in the nasopharynx. Diagnosis depends on typical signs and symptoms, such as acute ear pain and bulging of the tympanic membrane (eardrum) for AOM and hearing loss for OME; diagnostic modalities include (pneumatic) otoscopy, tympanometry and audiometry. Symptomatic management of ear pain and fever is the mainstay of AOM treatment, reserving antibiotics for children with severe, persistent or recurrent infections. Management of OME largely consists of watchful waiting, with ventilation (tympanostomy) tubes primarily for children with chronic effusions and hearing loss, developmental delays or learning difficulties. The role of hearing aids to alleviate symptoms of hearing loss in the management of OME needs further study. Insertion of ventilation tubes and adenoidectomy are common operations for recurrent AOM to prevent recurrences, but their effectiveness is still debated. Despite reports of a decline in the incidence of OM over the past decade, attributed to the implementation of clinical guidelines that promote accurate diagnosis and judicious use of antibiotics and to pneumococcal conjugate vaccination, OM continues to be a leading cause for medical consultation, antibiotic prescription and surgery in high-income countries.

    The impact of the mass media on woman's status was addressed at two 1995 conferences: the Fourth World Conference on Women, held in Beijing, China, and the Congress of the World Association for Christian Communication, held in Puebla, Mexico. The globalization process facilitated by the mass media has served to increase the power of patriarchy, with no advantages to the cause of women's rights. Coverage of popular movements has been suppressed out of deference to male-controlled governments. Coverage of the Beijing Conference highlighted celebrities and personal stories, to the exclusion of the economic and political issues under debate. Television has commodified women, reinforcing their oppression. On the other hand, the alternative media, which tend to be decentralized, democratic, low-cost, and low in technology, are presenting women as subjects rather than objects and deconstructing gender stereotypes. Of concern, however, is the tendency of computer technology to widen the gap between social classes and developed and developing countries. Women must use information networks to disseminate information on women's rights and strengthen the links between women throughout the world.

    Acute otitis media (AOM) is diagnosed based on visualization of a full or bulging tympanic membrane with middle ear effusion. The distribution of bacteria causing AOM in North America under the influence of pneumococcal conjugate vaccination and antibiotic selection pressure has resulted in a predominance of β-lactamase-producing Haemophilus influenzae followed by penicillin-resistant Streptococcus pneumoniae. Although guidelines continue to endorse amoxicillin as the preferred treatment, amoxicillin/clavulanate in high dosage would be the preferred treatment based on the otopathogen mix currently. Antibiotic prophylaxis has fallen into disfavor as a preventative strategy for AOM recurrences. PMID:23481107

  16. BrailleEasy: One-handed Braille Keyboard for Smartphones.

    PubMed

    2015-01-01

    The evolution of mobile technology is moving at a very fast pace. Smartphones are currently considered a primary communication platform where people exchange voice calls, text messages and emails. The human-smartphone interaction, however, is generally optimized for sighted people through the use of visual cues on the touchscreen, e.g., typing text by tapping on a visual keyboard. Unfortunately, this interaction scheme renders smartphone technology largely inaccessible to visually impaired people as it results in slow typing and higher error rates. Apple and some third party applications provide solutions specific to blind people which enables them to use Braille on smartphones. These applications usually require both hands for typing. However, Brailling with both hands while holding the phone is not very comfortable. Furthermore, two-handed Brailling is not possible on smartwatches, which will be used more pervasively in the future. Therefore, we develop a platform for one-handed Brailing consisting of a custom keyboard called BrailleEasy to input Arabic or English Braille codes within any application, and a BrailleTutor application for practicing. Our platform currently supports Braille grade 1, and will be extended to support contractions, spelling correction, and more languages. Preliminary analysis of user studies for blind participants showed that after less than two hours of practice, participants were able to type significantly faster with the BrailleEasy keyboard than with the standard QWERTY keyboard.

    The fresh outbreak of allergies and especially that increasingly early for food or even for new pneumallergens (sensitization already in utero) pushes us to test increasingly various and many allergens in children. The insufficiency of compliance of certain children to allergic skin tests encouraged us to seek new diagnostic methods. In our office we developed a new method of diagnosis by multipuncture, individualized and easily adaptable to each child. It is about a fast and reproductible prick-test which avoids stains and smudges due to the application of drops directly on the skin. It makes it possible to initially place easily all the tests on a plate (PIPET or Patient Individual Plate Easy Test) then on the skin by a multipuncture method. The tests can even already be prepared in the days which precede, provided that the plates are put in the fridge, with the name of the patient and the allergens used, for memory. It is about a rigorous test, reliable and careful, easy to carry out even in the most difficult children. PMID:12512189

    Clinicians must often perform statistical analyses for purposes such evaluating preexisting evidence and designing or executing clinical studies. R is a free software environment for statistical computing. R supports many statistical analysis functions, but does not incorporate a statistical graphical user interface (GUI). The R commander provides an easy-to-use basic-statistics GUI for R. However, the statistical function of the R commander is limited, especially in the field of biostatistics. Therefore, the author added several important statistical functions to the R commander and named it "EZR (Easy R)", which is now being distributed on the following website: http://www.jichi.ac.jp/saitama-sct/. EZR allows the application of statistical functions that are frequently used in clinical studies, such as survival analyses, including competing risk analyses and the use of time-dependent covariates and so on, by point-and-click access. In addition, by saving the script automatically created by EZR, users can learn R script writing, maintain the traceability of the analysis, and assure that the statistical process is overseen by a supervisor.

    Creating an infrastructure that is not ad hoc or ephemeral when much of technology today is itself ad hoc and ephemeral is not an easy task. This paper examines the collaboration process between various stakeholders within the Advanced Cooperative Arctic Data and Information Service (ACADIS) in order to provide insight into data management, data preservation, and data discovery. Specifically, this paper addresses the partnership of Arctic Research Mapping Application Program (ARMAP) and ACADIS. This partnership shows that what may seem like an easy or straight forward request can, in fact, prove challenging. These challenges can only be met through collaboration and good communication. The ACADIS project fosters scientific synthesis and discovery by providing services that make data freely available for access and analysis across multiple disciplines. The goals of ACADIS are to bring together experts to create tools at the forefront of how science will be done. Essentially, we improve the usability and interdisciplinary reuse of arctic data. ACADIS is a joint effort by the National Snow and Ice Data Center (NSIDC), the University Corporation for Atmospheric Research (UCAR), Unidata, and the National Center for Atmospheric Research (NCAR) to provide data archival services, preservation, and access for all projects funded by the National Science Foundation's (NSF) Arctic Science Program (ARC).

    Dipole-exchange spin waves in nanotubes composed of uniaxial ferromagnets are studied. An equation for the magnetic potential of linear spin waves in uniaxial "easy plane" ferromagnets is obtained in the magnetostatic approximation taking into account magnetic dipole-dipole interactions, exchange interactions, and anisotropy effects. A solution is found for this equation and a dispersion relation for these types of spin waves is obtained. The dependence of the spin wave frequency on the total wave number is found for the case of a thin nanotube. An expression is derived for the transverse wave number spectrum.

    With the advent of set-top boxes, the convergence of TV (broadcasting) and PC (Internet) is set to enter the home environment. Currently, a great deal of activity is occurring in developing standards (TV-Anytime Forum) and devices (TiVo) for local storage on Home Media Servers (HMS). These devices lie at the heart of convergence of the triad: communications/networks - content/media - computing/software. Besides massive storage capacity and being a communications 'gateway', the home media server is characterised by the ability to handle metadata and software that provides an easy to use on-screen interface and intelligent search/content handling facilities. In this paper, we describe a research prototype HMS that is being developed within the GigaCE project at the Telematica Instituut . Our prototype demonstrates advanced search and retrieval (video browsing), adaptive user profiling and an innovative 3D component of the Electronic Program Guide (EPG) which represents online presence. We discuss the use of MPEG-7 for representing metadata, the use of MPEG-21 working draft standards for content identification, description and rights expression, and the use of HMS peer-to-peer content distribution approaches. Finally, we outline explorative user behaviour experiments that aim to investigate the effectiveness of the prototype HMS during development.

    Here we conceive an innovative nanocomposite to endow hybrid perovskites with the easy processability of polymers, providing a tool to control film quality and material crystallinity. We verify that the employed semiconducting polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV), controls the self-assembly of CH₃NH₃PbI₃ (MAPbI₃) crystalline domains and favors the deposition of a very smooth and homogenous layer in one straightforward step. This idea offers a new paradigm for the implementation of polymer/perovskite nanocomposites towards versatile optoelectronic devices combined with the feasibility of mass production. As a proof-of-concept we propose the application of such nanocomposite in polymer solar cell architecture, demonstrating a power conversion efficiency up to 3%, to date the highest reported for MEH-PPV. On-purpose designed polymers are expected to suit the nanocomposite properties for the integration in diverse optoelectronic devices via facile processing condition.

  7. An easy to compare tool for more readable (physics) textbooks

    In this article, we show the easy way to compare the readability of two physics school texts written in the same language. We show that the readability of scholar texts depends on the frequency of terms. We compare the readability of texts from two physics textbooks written in Slovak. In these comparisons, we used the frequency of words and terms with a given length (probability distribution) instead of using a readability formula. The concept of analysing the frequency of words in a text agrees with our observations made by eye tracking systems. We verified our results by cloze tests. The method comparing the probability distribution of words and terms of two texts (written in the same language) is very simple, intuitive as well as language independent (in contrary to readability formulae).

  8. A geostationary Earth orbit satellite model using Easy Java Simulation

    2013-01-01

    We develop an Easy Java Simulation (EJS) model for students to visualize geostationary orbits near Earth, modelled using a Java 3D implementation of the EJS 3D library. The simplified physics model is described and simulated using a simple constant angular velocity equation. We discuss four computer model design ideas: (1) a simple and realistic 3D view and associated learning in the real world; (2) comparative visualization of permanent geostationary satellites; (3) examples of non-geostationary orbits of different rotation senses, periods and planes; and (4) an incorrect physics model for conceptual discourse. General feedback from the students has been relatively positive, and we hope teachers will find the computer model useful in their own classes.

  9. Why School is not Easy: An Analytical Perspective

    NASA Astrophysics Data System (ADS)

    Brooks, David W.

    2011-04-01

    An overarching theory that enables a systematic study of learning recently has been developed. Motivation, for example, is something we all think we know when we see. It was an important step to recognize that motivation can be conceptualized in terms of allocating working memory and especially attention to a learning task. The unified learning model (ULM) was synthesized from the literature with this in mind. Using the ULM as a basis for analysis, it is possible to consider all aspects of learning. A good place to begin concerns schools in general and why, in particular, school is not thought of as being easy. The ULM explains that allocating working memory often requires effort, and any exertion of such effort may be perceived as being hard. This paper is an analysis of school learning and especially science learning (STEM learning) in terms of the ULM.

  10. Easy and hard testbeds for real-time search algorithms

    1996-12-31

    Although researchers have studied which factors influence the behavior of traditional search algorithms, currently not much is known about how domain properties influence the performance of real-time search algorithms. In this paper we demonstrate, both theoretically and experimentally, that Eulerian state spaces (a super set of undirected state spaces) are very easy for some existing real-time search algorithms to solve: even real-time search algorithms that can be intractable, in general, are efficient for Eulerian state spaces. Because traditional real-time search testbeds (such as the eight puzzle and gridworlds) are Eulerian, they cannot be used to distinguish between efficient and inefficient real-time search algorithms. It follows that one has to use non-Eulerian domains to demonstrate the general superiority of a given algorithm. To this end, we present two classes of hard-to-search state spaces and demonstrate the performance of various real-time search algorithms on them.

    2011-06-01

    IBA Industrial Inc., (formerly known as Radiation Dynamics, Inc.) has been making high-energy and medium-energy, direct-current proton and electron accelerators for research and industrial applications for many years. Some industrial applications of high-power electron accelerators are the crosslinking of polymeric materials and products, such as the insulation on electrical wires, multi-conductor cable jackets, heat-shrinkable plastic tubing and film, plastic pipe, foam and pellets, the partial curing of rubber sheet for automobile tire components, and the sterilization of disposable medical devices. The curing (polymerization and crosslinking) of carbon and glass fiber-reinforced composite plastic parts, the preservation of foods and the treatment of waste materials are attractive possibilities for future applications. With electron energies above 1.0 MeV, the radiation protection for operating personnel is usually provided by surrounding the accelerator facility with thick concrete walls. With lower energies, steel and lead panels can be used, which are substantially thinner and more compact than the equivalent concrete walls. IBA has developed a series of electron processing systems called Easy-e-Beam™ for the medium energy range from 300 keV to 1000 keV. These systems include the shielding as an integral part of a complete radiation processing facility. The basic concepts of the electron accelerator, the product processing equipment, the programmable control system, the configuration of the radiation shielding and some performance characteristics are described in this paper.

    The Diagnostic System Development Shell (DSDS), an expert system development shell for diagnostic systems, is described. The major objective of building the DSDS is to create a very easy to use and friendly environment for knowledge engineers and end-users. The DSDS is written in OPS5 and CommonLisp. It runs on a VAX/VMS system. A set of domain independent, generalized rules is built in the DSDS, so the users need not be concerned about building the rules. The facts are explicitly represented in a unified format. A powerful check facility which helps the user to check the errors in the created knowledge bases is provided. A judgement facility and other useful facilities are also available. A diagnostic system based on the DSDS system is question driven and can call or be called by other knowledge based systems written in OPS5 and CommonLisp. A prototype diagnostic system for diagnosing a Philips constant potential X-ray system has been built using the DSDS.

  18. Easy Long-Term Identifiers and the "Data Paper"

    NASA Astrophysics Data System (ADS)

    Kunze, John

    2011-05-01

    A new publishing paradigm is needed to cope with the deluge of data artifacts produced by data-intensive science, many of which are vital to data re-use and verification of published scientific conclusions. Due to the limitations of traditional publishing, most of these artifacts are not usually disseminated, cited, or preserved. At the California Digital Library (CDL), one promising approach to the problem is to wrap these artifacts in the metaphor of a "data paper", assigning and managing data citations with our EZID (easy-eye-dee) identifier service. A data paper is a somewhat unfamiliar bundle of scholarly output with a familiar facade: minimally, a set of links to archived artifacts and a cover sheet containing familiar elements such as title, authors, date, abstract, and persistent identifier _ just enough to create basic citations, build "overlay journals", and enable discovery of data by internet search engines. Over time, we expect to add elements that permit deeper domain-specific discovery and re-use, such as variable names, methods, etc. At the same time, for data and identifiers that we manage, we will leverage as much domain-agnosticism data and identifier as possible.

    Web-based Virtual Tour has become a desirable and demanded application, yet challenging due to the nature of web application's running environment such as limited bandwidth and no guarantee of high computation power on the client side. Image-based rendering approach has attractive advantages over traditional 3D rendering approach in such Web Applications. Traditional geometry-based approach, such as VRML, requires labor-intensive 3D modeling process, high bandwidth and computation power especially for photo-realistic virtual scenes. QuickTime VR and IPIX as examples of image-based approach, use panoramic photos and the virtual scenes that can be generated from photos directly skipping the modeling process. But, QuickTime VR and IPIX may not only require special cameras or effort to take panoramic views but also provide only one fixed-point navigation (look-around and zooming in-out) rather than "walk around", that is a very important feature to provide immersive experience to virtual tourists. Easy and Effective Virtual Tour constructs virtual tour using several snap shots of conventional photos without special tools, build simple 3D space within each photo using spidery mesh, and expand the virtual spaces by connecting each other using simple user intervention to specify correspondence. The expanded virtual space provides virtual tourists with free navigation and immersive experience of walking around through the WWW.

  9. Self-Cleaning Particulate Prefilter Media

    NASA Technical Reports Server (NTRS)

    Weber, Olivia; Lalwani, San-jiv; Sharma, Anjal

    2012-01-01

    A long-term space mission requires efficient air revitalization performance to sustain the crew. Prefilter and particulate air filter media are susceptible to rapid fouling that adversely affects their performance and can lead to catastrophic failure of the air revitalization system, which may result in mission failure. For a long-term voyage, it is impractical to carry replacement particulate prefilter and filter modules due to the usual limitations in size, volume, and weight. The only solution to this problem is to reagentlessly regenerate prefilter and filter media in place. A method was developed to modify the particulate prefilter media to allow them to regenerate reagentlessly, and in place, by the application of modest thermocycled transverse or reversed airflows. The innovation may allow NASA to close the breathing air loop more efficiently, thereby sustaining the vision for manned space exploration missions of the future. A novel, self-cleaning coatings technology was developed for air filter media surfaces that allows reagentless in-place regeneration of the surface. The technology grafts thermoresponsive and nonspecific adhesion minimizing polymer nanolayer brush coatings from the prefilter media. These polymer nanolayer brush architectures can be triggered to contract and expand to generate a "pushing-off" force by the simple application of modestly thermocycled (i.e. cycling from ambient cabin temperature to 40 C) air streams. The nonspecific adhesion-minimizing properties of the coatings do not allow the particulate foulants to adhere strongly to the filter media, and thermocycled air streams applied to the media allow easy detachment and in-place regeneration of the media with minimal impact in system downtime or astronaut involvement in overseeing the process.

    A wealth of terrestrial remote sensing data has been collected and made public over the years from a variety of missions, but accessing this data and performing analysis on it has often been a time consuming and problematic task. J-Earth is a geospatial application that provides a quick and consistent means of accessing many terrestrial datasets which can then be analyzed and compared with each other. In addition to providing direct access to a number of preprocessed products based off of MODIS, ASTER, and TIMS datasets, J-Earth also makes it easy for a user to import their own data and work with it in an identical fashion. Users can easily work with both graphical and numeric datasets as well as vector/shapefile data. Numeric data can be viewed for a particular location through multiple datasets or plotted across an arbitrary profile line. Shapes can be used to find intersections with other shapefiles or to perform analytical calculations (mean, max, min, etc) upon numeric data within the bounds of a shape. These tools allow a user to quickly assess the geologic parameters of the area, including mineralogy, chemistry, surface temperature, topography and elevation. Additionally, J-Earth allows for temporal comparisons of regions for instruments which have repeat coverage over multiple years. J-Earth is part of the JMARS (Java Mission-planning and Analysis for Remote Sensing) suite of geospatial applications developed by the Mars Space Flight Facility at Arizona State University. This suite of software is used for mission planning and scientific data analysis by active NASA missions to Mars, the Moon, and Vesta. It is used by scientists, researchers and students of all ages from more than 40 countries around the world.

  11. Multimodality image integration for radiotherapy treatment: an easy approach

    The interest of using combined MR and CT information for radiotherapy planning is well documented. However, many planning workstations do not allow to use MR images, nor import predefined contours. This paper presents a new simple approach for transferring segmentation results from MRI to a CT image that will be used for radiotherapy planning, using the same original CT format. CT and MRI images of the same anatomical area are registered using mutual information (MI) algorithm. Targets and organs at risk are segmented by the physician on the MR image, where their contours are easy to track. A locally developed software running on PC is used for this step, with several facilities for the segmentation process. The result is transferred onto the CT by slightly modifying up and down the original Hounsfield values of some points of the contour. This is enough to visualize the contour on the CT, but does not affect dose calculations. The CT is then stored using the original file format of the radiotherapy planning workstation, where the technician uses the segmented contour to design the correct beam positioning. The described method has been tested in five patients. Simulations and patient results show that the dose distribution is not affected by the small modification of pixels of the CT image, while the segmented structures can be tracked in the radiotherapy planning workstation-using adequate window/level settings. The presence of the physician is not requires at the planning workstation, and he/she can perform the segmentation process using his/her own PC. This new approach makes it possible to take advantage from the anatomical information present on the MRI and to transfer the segmentation to the CT used for planning, even when the planning workstation does not allow to import external contours. The physician can draw the limits of the target and areas at risk off-line, thus separating in time the segmentation and planning tasks and increasing the efficiency.

    The Marine Geoscience Data System Media Bank (http://media.marine-geo.org) was constructed to enable the sharing of high quality images, illustrations and animations among members of the science community and to provide a new forum for education and public outreach (EPO). The initial focus of Media Bank was to serve Ridge 2000 research and EPO efforts, but it was constructed as a flexible system that could accommodate media from other multidisciplinary marine geoscience research initiatives. Media Bank currently contains digital photographs, maps, 3-D visualizations, and video clips from the Ridge 2000 and MARGINS focus sites as well as the Antarctic and Southern Ocean. We actively seek contributions of other high quality marine geoscience media for inclusion in Media Bank. Media Bank is driven by a relational database backend, enabling image browsing, sorting by category, keyword search functionality, and the creation of media galleries. All media are accompanied by a descriptive figure caption that provides easy access to expert knowledge to help foster data integration across disciplines as well as EPO efforts. In addition to access to high quality media, Media Bank also provides basic metadata including geographic position, investigator name and affiliation, as well as copyright information, and links to references and relevant data sets. Since media are tied to geospatial coordinates, a map-based interface is also provided for access to media.

Since minimal or no sample preparation is required, such ambient desorption/ionization techniques have been shown to provide direct, fast and selective fingerprinting characterization at the molecular level based on the pools of the most typical components. They have also been found to be applicable on intact, undisturbed samples or on simple solvent extracts. Fundamentals of EASI-MS and its sister techniques, including mechanisms, devices, parameters and strategies, as well as the many applications reported for food analysis, are summarized and discussed.

  11. 2,4,5-Trichlorophenoxyacetic acid promotes somatic embryogenesis in the rose cultivar "Livin' Easy" (Rosa sp.).

    Estabrooks, Tammy; Browne, Robin; Dong, Zhongmin

    2007-02-01

    Somatic embryogenesis (SE) offers vast potential for the clonal propagation of high-value roses. However, some recalcitrant cultivars unresponsive to commonly employed SE-inducing agents and low induction rates currently hinder the commercialization of SE technology in rose. Rose SE technology requires improvement before it can be implemented as a production system on a commercial scale. In the present work, we assessed 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a synthetic auxin not previously tested in rose, for its effectiveness to induce SE in the rose cultivar "Livin' Easy" (Rosa sp.). We ran a parallel comparison to the commonly used 2,4-dichlorophenoxyacetic acid (2,4-D). We tested each auxin with two different basal media: Murashige and Skoog (MS) basal medium and woody plant medium (WPM). MS medium resulted in somatic embryo production, whereas WPM did not. 2,4,5-T induced SE over a greater concentration range than 2,4-D's and resulted in significantly greater embryo yields. 2,4,5-T at a concentration of 10 or 25 microM was better for embrygenic tissue initiation than 2,4,5-T at 5 microM. Further embryo development occurred when the tissue was transferred to plant growth regulator (PGR) free medium or media with 40% the original auxin concentration. However, the PGR-free medium resulted in a high percentage of abnormal embryos (32.31%) compared to the media containing auxins. Upon transfer to germination medium, somatic embryos successfully converted into plantlets at rates ranging from 33.3 to 95.2%, depending on treatment. Survival rates 3 months ex vitro averaged 14.0 and 55.6% for 2,4-D- and 2,4,5-T-derived plantlets, respectively. Recurrent SE was observed in 60.2% of the plantlets growing on germination medium. This study is the first report of SE in the commercially valuable rose cultivar 'Livin' Easy' (Rosa sp.) and a suitable methodology was developed for SE of this rose cultivar.

    PubMed

    Schooler, C; Flora, J A

    1996-01-01

    In this review, we focus our discussion on studies examining effects on children and young adults. We believe that the current epidemic of youth violence in the United States justifies a focus on this vulnerable segment of society. We consider media effects on individual children's behaviors, such as imitating aggressive acts. In addition, we examine how the media influence young people's perceptions of norms regarding interpersonal relationships. Next, we assess mass media effects on societal beliefs, or what children and adolescents think the "real world" is like. We suggest these media influences are cumulative and mutually reinforcing, and discuss the implications of repeated exposure to prominent and prevalent violent media messages. Finally, we catalog multiple intervention possibilities ranging from education to regulation. From a public health perspective, therefore, we evaluate the effects that pervasive media messages depicting violence have on young people and present multiple strategies to promote more healthful outcomes.

    The concept of complementary media, which cause negative refraction and make perfect lenses, was first introduced to electromagnetic waves. This paper extends it to general waves by expressing the complementarity in terms of a transfer matrix. As an example, complementary media of electrons are discussed theoretically. An application of complementary media to subsurface imaging by scanning tunnelling microscopy is described. For realistic materials the formulation of complementary media is extended to take account of the scattering at interfaces, and effectively complementary systems formed by interfaces are discussed. Interfaces of the graphitic lattice forming complementary systems are designed.

    Suicide is a common and preventable event that is often reported by the media when there are sensationalistic elements or if the suicide involves a celebrity. Media reports of suicide can induce a copycat or "Werther effect". There is increasing evidence that sensationalistic reporting of suicides has a direct effect on increasing suicide rates. Responsible reporting guidelines drawn up in consultation with media professionals have been shown to improve reporting of suicides. Local reporting on suicides tends to be sensationalistic but also has a strong educational slant. The media should educate both the public and the medical professional about their role in suicide prevention. PMID:18989499

    We report the effective methods to induce weak ferromagnetism in pristine MoS2 persisting up to room temperature with the improved transport property, which would lead to new spintronics devices. The hydrogenation of MoS2 by heating at 300 °C for 1 h leads to the easy axis out of plane, while the irradiation of proton with a dose of 1 × 10(13) P/cm(2) leads to the easy axis in plane. The theoretical modeling supports such magnetic easy axes.

  11. High resolution analytical transmission electron microscopy of magnetic recording media

    NASA Astrophysics Data System (ADS)

    Risner, Juliet Danielle

    Since the invention of the hard disk drive in 1954, the density of bits per disk has increased exponentially. This trend is partly due to improvements to the magnetic recording media. In current hard disks, each bit is approximately 0.04 mum in its smallest dimension and comprises ˜100 hexagonal close packed Co-alloy magnetic grains. These grains have magnetic "easy" axes oriented longitudinally, or parallel to the film plane. Future recording media have easy axes oriented perpendicular to the film plane. Perpendicular media are expected to provide continued increases in storage density above the limit of longitudinal media. Quantum-mechanical exchange coupling between magnetic grains degrades the signal-to-noise ratio (SNR) and limits storage density in both media types. Controlling exchange coupling is possible by creating nonmagnetic grain boundaries which compositionally isolate the magnetic grains. High-resolution analytical transmission electron microscopy (TEM) is required to study these media because of their nano-scale grains and grain boundaries. Examining the microstructure and elemental distribution in these films at near atomic level is paramount to understanding their magnetic performance. The microstructure and elemental distribution in longitudinal and perpendicular media were examined using high resolution analytical TEM techniques, such as energy-filtered TEM (EFTEM), energy-dispersive x-ray spectroscopy (EDS) using a 1.5 nm electron probe, and spectrum imaging with a scanning TEM. These techniques successfully determined how grain boundary Cr segregation varies with grain orientation in longitudinal media. Boundaries misoriented by 0° and 90° commonly occur and were found to have minimal Cr segregation, which limits storage density improvement in these media. Analytical TEM techniques applied to oxygen-enriched perpendicular media, fabricated using different deposition methods, effectively related microstructure and composition to magnetic

  12. Rotary Microfilter Media Evaluation

    Poirier, M

    2005-04-20

    Savannah River National Laboratory (SRNL) received funding from DOE EM-21, Office of Cleanup Technologies, to develop the rotary microfilter for high level radioactive service. One aspect of this project evaluated alternative filter media to select one for the 2nd generation rotary microfilter being procured as a prefilter to a small column ion exchange process. The authors conducted screening tests on a variety of filter media and pore sizes using a stirred cell followed by pilot-scale testing on a more limited number of filter media and pore sizes with a three disk rotary microfilter. These tests used 5.6 molar sodium supernate, and sludge plus monosodium titanate (MST) solids. The conclusions from this work are: (1) The 0.1 {micro} nominal TruMem{reg_sign} ceramic and the Pall PMM M050 (0.5 {micro} nominal) stainless steel filter media produced the highest flux in rotary filter testing. (2) The Pall PMM M050 media produced the highest flux of the stainless steel media tested in rotary filter testing. (3) The Pall PMM M050 media met filtrate quality requirements for the rotary filter. (4) The 0.1 {micro} TruMem{reg_sign} and 0.1 {micro} Pall PMM media met filtrate quality requirements as well. (5) The Pall PMM M050 media produced comparable flux to the 0.1 {micro} TruMem{reg_sign} media, and proved more durable and easier to weld. Based on these test results, the authors recommend Pall PMM M050 filter media for the 2nd generation rotary microfilter.

    The initial objectives of this effort were to provide a hardware and software platform that can address the requirements for the accountability of classified removable electronic media and vault access logging. The Media Tracker system software assists classified media custodian in managing vault access logging and Media Tracking to prevent the inadvertent violation of rules or policies for the access to a restricted area and the movement and use of tracked items. The MediaTracker system includes the software tools to track and account for high consequence security assets and high value items. The overall benefits include: (1) real-time access to the disposition of all Classified Removable Electronic Media (CREM), (2) streamlined security procedures and requirements, (3) removal of ambiguity and managerial inconsistencies, (4) prevention of incidents that can and should be prevented, (5) alignment with the DOE's initiative to achieve improvements in security and facility operations through technology deployment, and (6) enhanced individual responsibility by providing a consistent method of dealing with daily responsibilities. In response to initiatives to enhance the control of classified removable electronic media (CREM), the Media Tracker software suite was developed, piloted and implemented at the Los Alamos National Laboratory beginning in July 2000. The Media Tracker software suite assists in the accountability and tracking of CREM and other high-value assets. One component of the MediaTracker software suite provides a Laboratory-approved media tracking system. Using commercial touch screen and bar code technology, the MediaTracker (MT) component of the MediaTracker software suite provides an efficient and effective means to meet current Laboratory requirements and provides new-engineered controls to help assure compliance with those requirements. It also establishes a computer infrastructure at vault entrances for vault access logging, and can accommodate

  5. Magnetohydrodynamics of fractal media

    SciTech Connect

    Tarasov, Vasily E.

    2006-05-15

    The fractal distribution of charged particles is considered. An example of this distribution is the charged particles that are distributed over the fractal. The fractional integrals are used to describe fractal distribution. These integrals are considered as approximations of integrals on fractals. Typical turbulent media could be of a fractal structure and the corresponding equations should be changed to include the fractal features of the media. The magnetohydrodynamics equations for fractal media are derived from the fractional generalization of integral Maxwell equations and integral hydrodynamics (balance) equations. Possible equilibrium states for these equations are considered.

  15. Naive empiricism and dogmatism in confidence research: a critical examination of the hard-easy effect.

    PubMed

    Juslin, P; Winman, A; Olsson, H

    2000-04-01

    Two robust phenomena in research on confidence in one's general knowledge are the overconfidence phenomenon and the hard-easy effect. In this article, the authors propose that the hard-easy effect has been interpreted with insufficient attention to the scale-end effects, the linear dependency, and the regression effects in data and that the continued adherence to the idea of a "cognitive overconfidence bias" is mediated by selective attention to particular data sets. A quantitative review of studies with 2-alternative general knowledge items demonstrates that, contrary to widespread belief, there is (a) very little support for a cognitive-processing bias in these data; (b) a difference between representative and selected item samples that is not reducible to the difference in difficulty; and (c) near elimination of the hard-easy effect when there is control for scale-end effects and linear dependency.

  16. EasyKSORD: A Platform of Keyword Search Over Relational Databases

    NASA Astrophysics Data System (ADS)

    Peng, Zhaohui; Li, Jing; Wang, Shan

    Keyword Search Over Relational Databases (KSORD) enables casual users to use keyword queries (a set of keywords) to search relational databases just like searching the Web, without any knowledge of the database schema or any need of writing SQL queries. Based on our previous work, we design and implement a novel KSORD platform named EasyKSORD for users and system administrators to use and manage different KSORD systems in a novel and simple manner. EasyKSORD supports advanced queries, efficient data-graph-based search engines, multiform result presentations, and system logging and analysis. Through EasyKSORD, users can search relational databases easily and read search results conveniently, and system administrators can easily monitor and analyze the operations of KSORD and manage KSORD systems much better.

  17. Systematic review of EASY-care needs assessment for community-dwelling older people

    PubMed Central

    2015-01-01

    Background: undertaking comprehensive geriatric assessments (CGAs) combined with long-term health and social care management can improve the quality of life of older people [ 1]. The EASY-Care tool is a CGA instrument designed for assessing the physical, mental and social functioning and unmet health and social needs of older people in community settings or primary care. It has also been used as a frailty assessment tool and for gathering population-level data. Objective: to review the evidence of reliability, validity and acceptability of EASY-Care and its appropriateness for assessing the needs of community-dwelling older people. Methods: systematic search of literature databases using pre-defined search terms (January 1994—May 2014) for English language articles reporting on the reliability, validity, acceptability and implementation of EASY-Care in primary care and community settings. Eligible articles were critically reviewed. Discussion papers mapping professionals' use of the tool were also included as these could be considered an aspect of validity. Results: twenty-nine papers met the inclusion criteria and underwent data extraction. A narrative synthesis was performed, because there was a variety of quantitative and qualitative outcomes and characteristics. Reliability evidence for EASY-Care is minimal. Evidence for validity is good, and it has received numerous positive endorsements of acceptability in international settings from older people and practitioners. Conclusion: evidence supports the use of EASY-Care for individual needs assessment; further research is needed for other uses. Of the papers that made statements about who should administer EASY-Care, the majority indicated that nurses were preferable to self-completion. PMID:25911539

Using EASIE, programs are integrated through a relational database management system. Volume 1, Executive Overview, gives an overview of the functions provided by EASIE and describes their use. Three operational design systems based upon the EASIE software are briefly described.

  19. Children's media policy.

    PubMed

    Jordan, Amy B

    2008-01-01

    Amy Jordan addresses the need to balance the media industry's potentially important contributions to the healthy development of America's children against the consequences of excessive and age-inappropriate media exposure. Much of the philosophical tension regarding how much say the government should have about media content and delivery stems from the U.S. Constitution's First Amendment protection against government interference in free speech, including commercial speech. Courts, Jordan says, have repeatedly had to weigh the rights of commercial entities to say what they please against the need to protect vulnerable citizens such as children. This balancing act is complicated even further, she says, because many government regulations apply only to broadcast television and not to non-broadcast media such as the Internet or cable television, though Congress has addressed the need to protect children's privacy online. The need to protect both free speech and children has given rise to a fluid media policy mix of federal mandates and industry self-regulation. Jordan describes the role of the three branches of the federal government in formulating and implementing media policy. She also notes the jockeying for influence in policymaking by industry lobbies, child advocacy groups, and academic researchers. The media industry itself, says Jordan, is spurred to self-regulation when public disapproval grows severe enough to raise the possibility of new government action. Jordan surveys a range of government and industry actions, from legislatively required parental monitoring tools, such as the V-Chip blocking device on television sets, to the voluntary industry ratings systems governing television, movies, and video games, to voluntary social website disclosures to outright government bans, such as indecency and child privacy information collection. She considers the success of these efforts in limiting children's exposure to damaging content and in improving parents

  1. Model for the easy-axis alignment of chemically synthesized L10 FePt nanoparticles

    NASA Astrophysics Data System (ADS)

    Harrell, J. W.; Kang, S.; Jia, Z.; Nikles, D. E.; Chantrell, R.; Satoh, A.

    2005-11-01

    Analytical and computational models of the easy-axis orientation process in magnetic nanoparticle systems are investigated and compared with experimental data. The computational model gives good agreement with experiment on the assumption of a reduced anisotropy constant, which is ascribed to the existence of aggregation. It is found that the degree of orientation depends on the parameter KV /kT, with K the anisotropy constant and V the nanoparticle volume, which governs the coupling of the easy axis to the magnetic moment. A simple and useful analytical expression is derived, from which the primary conditions for good alignment are determined.

    NASA Astrophysics Data System (ADS)

    Korneta, W.; Pytel, Z.

    1987-08-01

    The spin model of single domain ferromagnetic film is considered. Only the nearest-neighbor interactions are taken into account. The interactions depend on distances from surfaces. The external magnetic field is applied perpendicular to the easy axis lying in the plane of the film. The thermodynamic behaviour of the model is studied near the second-order ferro-paramagnetic phase transition for the component of the magnetization in the direction of the easy axis. The molecular-field theory is used. The phase diagram and profiles of the order parameter are obtained. Different feasible investigations of the phase transition are compared.

    DOE PAGES

    Hayami, Satoru; Lin, Shi-Zeng; Batista, Cristian D.

    2016-05-12

    We clarify the conditions for the emergence of multiple-Q structures out of lattice and easy-axis spin anisotropy in frustrated magnets. By considering magnets whose exchange interaction has multiple global minima in momentum space, we find that both types of anisotropy stabilize triple-Q orderings. Moderate anisotropy leads to a magnetic field-induced skyrmion crystal, which evolves into a bubble crystal for increasing spatial and spin anisotropy. Finally, the bubble crystal exhibits a quasi-continuous (devil’s staircase) temperature dependent ordering wave-vector, characteristic of the competition between frustrated exchange and strong easy-axis anisotropy.

    Recently, there has been no escaping the mention of blogs in the media. Blogging has emerged as a social phenomenon, which has impacted politics, business, and communication. Blogging software has enabled people with limited knowledge of the Internet to publish their thoughts online and participate in a global conversation; whereas the Blogosphere has hyperaccelerated the spread of information. Technorati, a blog search engine is now tracking over 7.8 million Weblogs, and 937 million links, and reports that there are about 30,000 to 40,000 new blogs created a day. The majority of people who blog do so as a hobby, using blogs to publish their thoughts, feelings, and viewpoints on whatever topics interest them. Blogging software also enables people to post pictures, music, and more recently videos. For many people blogs are used as online journals or diaries; other people use blogs to communicate with their family and friends. Whether people generate revenue with their blogs or use them as a hobby the one thing they all have in common is that they are part of the Blogosphere, or network of blogs that gives people a voice and allows them to spread information at an unprecedented rate. Although searching PubMed produces few results for "blog" (6 relevant articles of 24), "weblog" (1 article), web log (8 entries of varying relevance), and "blogging" (4 articles) (none of which were in Radiology, RadioGraphics, AJR, or JVIR), blogging might well become an important means of information transfer in Radiology also.

    1993-01-01

    The government faces a crisis in data storage, analysis, archive, and communication. The sheer quantity of data being poured into the government systems on a daily basis is overwhelming systems ability to capture, analyze, disseminate, and store critical information. Future systems requirements are even more formidable: with single government platforms having data rate of over 1 Gbit/sec, greater than Terabyte/day storage requirements, and with expected data archive lifetimes of over 10 years. The charter of the National Media Laboratory (NML) is to focus the resources of industry, government, and academia on government needs in the evaluation, development, and field support of advanced recording systems.

  15. Easy-plane anisotropy stabilizes skyrmions in 2D chiral magnets

    NASA Astrophysics Data System (ADS)

    Rowland, James; Banerjee, Sumilan; Randeria, Mohit

    2014-03-01

    Experiments on two-dimensional (2D) chiral magnetic materials, like thin films of non-centrosymmetric helimagnets and metallic magnetic layers, have revealed interesting spatially modulated spin textures such as spirals and skyrmions. Motivated by this we study the ground-state phase diagram for a 2D chiral magnet in a magnetic field using a Ginzburg-Landau model, with Dzyaloshinskii-Moriya (DM) term, anisotropic exchange and single-ion anisotropy. The easy-axis anisotropy region of the phase diagram has been well-studied, whereas the easy-plane region has not been discussed. In the easy-plane region, we find an unexpectedly large stable skyrmion crystal (SkX) phase in a perpendicular magnetic field. We find re-entrant transitions between ferromagnetic and SkX phases, and intriguing internal structure of the skyrmion core with two-length scales. We argue that such an easy-plane anisotropy arises naturally from the compass terms induced by spin-orbit coupling that is also responsible for the DM term, as proposed recently in the context of oxide interfaces. We also discuss the phase diagram in a tilted field configuration, relevant for torque magnetometry experiments. JR and MR supported by NSF MRSEC DMR-0820414 and SB by DOE-BES DE-SC0005035.

  19. Deconfined criticality in ``easy-plane'' SU(N) anti-ferromagnets

    NASA Astrophysics Data System (ADS)

    D'Emidio, Jonathan; Murthy, Ganpathy; Kaul, Ribhu

    Motivated by evidence for deconfined criticality in SU(N) anti-ferromagnets, we investigate the phase diagram of these models in the case where the SU(N) symmetry is reduced to rotations about the diagonal generators (''easy-plane'' symmetry). We carry out extensive numerical simulations using quantum Monte Carlo, revealing a first-order magnetic to valence bond solid phase transition that becomes a continuous deconfined transition at large N. We support our numerical data by performing epsilon expansions of the easy-plane deformed CP N - 1 field theory near both the upper and lower critical dimensions. This renormalization group analysis shows that the symmetric deconfined fixed point is unstable in the presence of easy-plane anisotropy, resulting in a runaway flow for intermediate values of N and a flow towards a stable easy-plane deconfined fixed point at large N, which is consistent with the critical behavior of our lattice models. This research was partially financially supported by NSF DMR-1056536.

    In 1978 a literature search on selective blocking of fluid flow in porous media was done by Professor S.S. Marsden and two of his graduate students, Tom Elson and Kern Huppy. This was presented as SUPRI Report No. TR-3 entitled ''Literature Preview of the Selected Blockage of Fluids in Thermal Recovery Projects.'' Since then a lot of research on foam in porous media has been done on the SUPRI project and a great deal of new information has appeared in the literature. Therefore we believed that a new, up-to-date search should be done on foam alone, one which would be helpful to our students and perhaps of interest to others. This is a chronological survey showing the development of foam flow, blockage and use in porous media, starting with laboratory studies and eventually getting into field tests and demonstrations. It is arbitrarily divided into five-year time periods. 81 refs.

  1. Switching of magnetic easy-axis using crystal orientation for large perpendicular coercivity in CoFe2O4 thin film

    NASA Astrophysics Data System (ADS)

    Shirsath, Sagar E.; Liu, Xiaoxi; Yasukawa, Yukiko; Li, Sean; Morisako, Akimitsu

    2016-07-01

    Perpendicular magnetization and precise control over the magnetic easy axis in magnetic thin film is necessary for a variety of applications, particularly in magnetic recording media. A strong (111) orientation is successfully achieved in the CoFe2O4 (CFO) thin film at relatively low substrate temperature of 100 °C, whereas the (311)-preferred randomly oriented CFO is prepared at room temperature by the DC magnetron sputtering technique. The oxygen-deficient porous CFO film after post-annealing gives rise to compressive strain perpendicular to the film surface, which induces large perpendicular coercivity. We observe the coercivity of 11.3 kOe in the 40-nm CFO thin film, which is the highest perpendicular coercivity ever achieved on an amorphous SiO2/Si substrate. The present approach can guide the systematic tuning of the magnetic easy axis and coercivity in the desired direction with respect to crystal orientation in the nanoscale regime. Importantly, this can be achieved on virtually any type of substrate.

  3. Using the media.

    PubMed

    1994-01-01

    To use the mass media (newspaper, radio, and TV) to reach a large audience with information about AIDS, it is important to choose the media outlets carefully, since they use information that satisfies their audience in content and style. For example, radio, TV, or videos are best to reach illiterate groups. Ways to approach each sector of the written and electronic media include press releases, news conferences, information kits, and personal contacts. Letters to the editor and offers of submitting articles for publication are additional ways to approach newspapers. Audio- or videocassettes with interviews or images conveying HIV/AIDS prevention messages can be submitted to TV and radio stations. It is important to present the information attractively to gain the journalists' attention. News releases should include sources of information and a contact name. It is important to inform the mass media of successes revolving around AIDS prevention, emphasizing local successes. One should identify what media slots have the most influence. For example, a medical officer in Chiang Mai, Thailand, notes that popular disc jockeys have more influence than do government information broadcasts. It is best to promote facts that probably will increase support for AIDS prevention campaigns. If possible, groups should seek free space or air time for AIDS prevention messages. AIDS prevention messages should not use fear because it does not promote safer sexual behavior. Instead, they should link condom use with a sense of independence, responsibility, and being fashionable. Leaflets, posters, videotapes, slides, displays, slogans, audiocassettes, T-shirts, stickers, and other activities or products reinforce the effectiveness of media campaigns. Interviews with or feature articles and programs about people infected or affected by HIV/AIDS chip away at the belief that "AIDS could never happen to me." PMID:12287965

    Escobar-Chaves, Soledad Liliana; Anderson, Craig A

    2008-01-01

    Liliana Escobar-Chaves and Craig Anderson investigate two important trends among American youth and examine the extent to which the two trends might be related. First, the authors note that U.S. youth are spending increasing amounts of time using electronic media, with the average American youngster now spending one-third of each day with some form of electronic media. Second, the authors demonstrate that American adolescents are engaging in a number of unhealthful behaviors that impose huge societal costs. Escobar-Chaves and Anderson detail the extent of five critical types of adolescent health risk behaviors identified by the Centers for Disease Control and Prevention-obesity, smoking, drinking, sexual risk taking, and violence. Obesity, the authors note, has become an epidemic among America's young people. Cigarette smoking among adolescents is one of the ten leading health indicators of greatest government concern. Alcohol abuse and alcohol dependence are widespread problems among the nation's youth and are the source of the three leading causes of death among youth. More than 20 percent of American high school students have sexual intercourse for the first time before they reach the age of fourteen. And twelve- to twenty-year-olds perpetrated 28 percent of the single-offender and 41 percent of multiple-offender violent crimes in the United States in 2005. Escobar-Chaves and Anderson present and evaluate research findings on the influence of electronic media on these five risk behaviors among adolescents. Researchers, they say, have found modest evidence that media consumption contributes to the problem of obesity, modest to strong evidence that it contributes to drinking and smoking, and strong evidence that it contributes to violence. Research has been insufficient to find links between heavy media exposure and early sexual initiation. The authors note the need for more large-scale longitudinal studies that specifically examine the cumulative effects of

    The public information media provides information on current events (news), entertainment (programming), and opinions offered by trusted public sources (e.g., business, academic or religious spokespersons, journalists, and government officials). Consequently, it is a major force in shaping a populace's attitudes toward significant social issues and of great interest to intervention planners. The chapter attempts to provide modelers and intervention analysts alike with sufficient understanding of media mechanisms and current research that they can begin contributing to, and benefiting from this important area of study.

The mission of the NML is to support current government user data storage needs and assist them in getting the most efficient 'commercial' solutions in the future. The motivation for a National Media Laboratory is as follows: recording systems are the major government image and data exploitation bottleneck; government data recording performance and storage requirements lead commercial practice by 3-5 years; the supporting commercial recorder industry is large but principally focused on video not data formats; lack of standards; and lack of transfer of commercial knowledge base to program offices and operational sites.

The bacteria that most often cause AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Differentiating AOM from otitis media with effusion (OME) is a critical skill for physicians, as accurate diagnosis will guide appropriate treatment of these conditions.

First, we recall the derivation of systems governing the interaction process for waves propagating in such media and we check the local and global well-posedness of the corresponding Cauchy problem. Then, we look for stationary states in the context of normal or anomalous dispersion regimes, that lead us to either elliptic or non-elliptic systems and we address the problem of orbital stability. Finally, some numerical experiments are carried out in order to compute localized states for several regimes and to study dynamic stability as well as long-time asymptotics.

    Implicit Media Knowledge aims to provide relevant information related to visual media without effort. It is based on the analysis of media usage from several users (e.g. a community). Algorithms based on clustering methods that extract relevant information (e.g. tags, taxonomy trees) related to a media from its usage are detailed. To validate our new approach, we propose to apply our concept and algorithms on a specific media use such as the analysis of how multiple users organize their media files. Significant results of two experiments will be highlighted. Perspectives of our work will be finally presented.

  5. [Contrast media in echography].

    1992-09-01

    In medical US, the use of specific contrast media to increase the echogenicity of structures and organs changes their absorption of the US beam, and modifies the through-transmission velocity. This can be of great diagnostic value. Contrast media can help depict vessels and cavities, increase the sensitivity of Doppler examination, and make the differentiation of normal and pathologic tissues easier. The products which are currently available do not completely fulfill the needs of clinical researchers. The first papers reporting on some clinical applications of these contrast media in humans are now appearing in literature. Contrast media for diagnostic US can be classified in five groups: 1) free gas bubbles; 2) stabilized gas bubbles; 3) colloidal suspensions; 4) emulsions; 5) aqueous solutions. These agents are quite different, as to both chemical and physical features and distribution within living tissues. Different clinical applications are thus possible for each of them; a unique contrast medium which will meet all the needs of the various clinical situations seems inconceivable at present. Most probably, a variety of products will develop, each with its own application field; in clinical practice, it seems likely that different products will be used, according to the specific clinical needs.

    2010-01-01

    Generally, Tailas and Ghritas have been prepared by using Kalka (paste) and Drava dravya (liquid media usually SwaRasa or Kwatha). However, Apamarga Kshara taila is prepared by using Apamarga Kshara drava (the alkali is obtained after dissolving it in water, after obtaining it by burning, dissolving, and filtration of the same plant). Therefore, to evaluate the role of the media during the preparation, the Taila was prepared in different samples by using the fresh and dry paste of Apamarga along with SwaRasa and Kwatha of Apamarga. All the samples were tested through various analytical parameters, that is, pH, acid value, iodine value, saponification value, and soon. Finally, it was found that Apamarga Kshara taila prepared by using fresh Kalka and Ksharajala was better and it was also an easy pharmaceutical procedure. PMID:22131746

    We investigated via micromagnetic simulation the effect of thermal fluctuation on the stability and transition width of a tilted media with easy axis oriented at 45° and 135° with respect to the vertical along the down-track direction. A dynamic model of the recording process is presented which incorporates a Westmijze head field rotated by 90°. Thermal fluctuations are modeled via a stochastic Landau-Lifshitz-Gilbert equation with a temperature-dependent white-noise field. The dependence of the transition parameter a between adjacent bits and signal-to-noise ratio on temperature is investigated, and comparison between these values of the perpendicular medium and those of the two types of tilted media is performed.

    2012-10-01

    Patterned media (PM) for magnetic information storage have received increased attention in recent years as the primary candidate for 1 Terabit/in2 or higher recording density for computer hard disk drives. A PM consists of a periodic array of well-defined magnetic islands, each of which can store one bit of data. In the simplest scheme, the structures could be magnetic pillars and dots with a single easy axis of magnetization. The direction of detected magnetization by the read/write head is interpreted as a binary signal 1 or 0. Some of the main technical issues in the PM include the difficulty in fabricating small nanoisland arrays in a periodic fashion over large areas, reliability/reproducibility of magnetic bit characteristics, as well as wear and head flyability issues associated with the media surface roughness, and processing cost. This article deals with a recent investigation of various fabrication approaches, nanostructural features, and magnetic properties for the bit PM.

    The accurate handling of different chemical file formats and the consistent conversion between them play important roles for calculations in complex cheminformatics workflows. Working with different cheminformatic tools often makes the conversion between file formats a mandatory step. Such a conversion might become a difficult task in cases where the information content substantially differs. This paper describes UNICON, an easy-to-use software tool for this task. The functionality of UNICON ranges from file conversion between standard formats SDF, MOL2, SMILES, PDB, and PDBx/mmCIF via the generation of 2D structure coordinates and 3D structures to the enumeration of tautomeric forms, protonation states, and conformer ensembles. For this purpose, UNICON bundles the key elements of the previously described NAOMI library in a single, easy-to-use command line tool.

  4. Influence of thermal agitation on the electric field induced precessional magnetization reversal with perpendicular easy axis

    2013-12-15

    We investigated the influence of thermal agitation on the electric field induced precessional magnetization switching probability with perpendicular easy axis by solving the Fokker-Planck equation numerically with finite difference method. The calculated results show that the thermal agitation during the reversal process crucially influences the switching probability. The switching probability can be achieved is only determined by the thermal stability factor Δ of the free layer, it is independent on the device dimension, which is important for the high density device application. Ultra-low error rate down to the order of 10{sup −9} can be achieved for the device of thermal stability factor Δ of 40. Low damping factor α material should be used for the free layer for high reliability device applications. These results exhibit potential of electric field induced precessional magnetization switching with perpendicular easy axis for ultra-low power, high speed and high density magnetic random access memory (MRAM) applications.

    This is the second interim report jointly prepared by NASA and easyJet on the work performed under the agreement to collaborate on a study of the factors entailed in flight and cabin-crew fatigue, and decreases in performance associated with fatigue. The objective of this Agreement is to generate reliable procedures that aid in understanding the levels and characteristics of flight and cabin-crew fatigue factors, both latent and proximate, whose confluence will likely result in unacceptable crew performance. This study entails the analyses of numerical and textual data collected during operational flights. NASA and easyJet are both interested in assessing and testing NASA s automated capabilities for extracting operationally significant information from very large, diverse (textual and numerical) databases; much larger than can be handled practically by human experts.

  6. Easy and direct method for calibrating atomic force microscopy lateral force measurements.

    PubMed

    Liu, Wenhua; Bonin, Keith; Guthold, Martin

    2007-06-01

    We have designed and tested a new, inexpensive, easy-to-make and easy-to-use calibration standard for atomic force microscopy (AFM) lateral force measurements. This new standard simply consists of a small glass fiber of known dimensions and Young's modulus, which is fixed at one end to a substrate and which can be bent laterally with the AFM tip at the other end. This standard has equal or less error than the commonly used method of using beam mechanics to determine a cantilever's lateral force constant. It is transferable, thus providing a universal tool for comparing the calibrations of different instruments. It does not require knowledge of the cantilever dimensions and composition or its tip height. This standard also allows direct conversion of the photodiode signal to force and, thus, circumvents the requirement for a sensor response (sensitivity) measurement.

  7. Easy Fabrication of Thin Membranes with Through Holes. Application to Protein Patterning

    2012-01-01

    Since protein patterning on 2D surfaces has emerged as an important tool in cell biology, the development of easy patterning methods has gained importance in biology labs. In this paper we present a simple, rapid and reliable technique to fabricate thin layers of UV curable polymer with through holes. These membranes are as easy to fabricate as microcontact printing stamps and can be readily used for stencil patterning. We show how this microfabrication scheme allows highly reproducible and highly homogeneous protein patterning with micron sized resolution on surfaces as large as 10 cm2. Using these stencils, fragile proteins were patterned without loss of function in a fully hydrated state. We further demonstrate how intricate patterns of multiple proteins can be achieved by stacking the stencil membranes. We termed this approach microserigraphy. PMID:22952944

  8. Magnetization process in holmium: easy axis spin reorientation induced by the magnetostrictive basal plane distortion.

    PubMed

    Benito, L; Ciria, M; de la Fuente, C; Arnaudas, J I; Ward, R C C; Wells, M R

    2005-06-10

    We report on the change of the easy axis direction in holmium, from the a to the b axis, under the application of a magnetic field in the basal plane. This spin reorientation is observed by measuring the magnetic torque in Ho(n)/Lu(15) superlattices (n and 15 are the number of atomic planes in the Ho and Lu blocks). We also observe that, at the field H0 and temperature at which the reorientation occurs, both axes are easy directions. Based on the fact that the field H0 depends on n in the same way as the field-induced magnetoelastic distortion does, we propose that this spin reorientation originates from the strong field-induced magnetoelastic deformation within the basal plane. The modulation of the alpha strains with sixfold symmetry originates a 12-fold term in the magnetic anisotropy energy.

    The semi-filamentous multicellular cyanobacterium Limnothrix/Pseudanabaena sp. strain ABRG5-3 undergoes autolysis, which involves the accumulation of polyphosphate compounds and disintegration of thylakoid membranes in cells, as a unique feature that occurs due to growth conditions. In this study, the overexpression and easy recovery of alkane (a saturated hydrocarbon, C17H36) as a biofuel were examined in recombinants of the cyanobacteria ABRG5-3 and Synechocystis sp. strain PCC6803. The results obtained indicated that the accumulated mass of alkane accounted for ∼50 or 60% of the dry weight of ABRG5-3 or PCC6803 recombinant cells, respectively. Furthermore, cultivating cells in liquid medium BG11 in which the nitrogen resource had been depleted promoted the production of alkane and cell lysis, resulting in the easy recovery of target products from the supernatant.

    Staphylococcus epidermidis is one of the major concerns with respect to hospital-acquired infections. Therefore, a rapid and easy method to identify at species level S. epidermidis isolates out of a broad range of bacteria is necessary. Based on earlier studies, the sesC gene encoding a S. epidermidis surface protein revealed to be a highly conserved gene in this species. By means of an easy and inexpensive PCR assay, the presence of sesC was checked in 438 clinical staphylococcal isolates. Results showed that sesC is specifically present in all S. epidermidis. In conclusion, the sesC gene can be exploited as a genetic marker in order to distinguish S. epidermidis from other isolates.

    Partially ordered Fe{sub 53}Pt{sub 47} nanoparticles with size around 8 nm were prepared by the simultaneous decomposition of iron pentacarbonyl and platinum acetylacetonate. The high boiling point chemical, hexadecylamine, was used as a solvent, and 1-adamantanecarboxylic acid was used as a stabilizer. X-ray diffraction measurements reveal that as-made FePt particles were partially transformed into the ordered L1{sub 0} phase with some weak superlattice peaks. The room-temperature hysteresis loop and remanence curve suggest a broad distribution of anisotropies in the partially ordered particles. By coating the partially ordered FePt nanoparticles with a polyvinylchloride polymer binder, the particles could be re-dispersed in cyclohexanone. Furthermore, the easy axis of the particles coated with the polyvinylchloride polymer binder could be aligned under an external field. Easy axis alignment was confirmed from both alternating gradient magnetometer and x-ray diffraction measurements.

    Survival curves are frequently used for reporting survival or mortality outcomes of experimental pharmacological/toxicological studies and of clinical trials. Microsoft Excel is a simple and widely used tool for creation of numerous types of graphic presentations however it is difficult to create step-wise survival curves in Excel. Considering the familiarity of clinicians and biomedical scientists with Excel, an algorithm survival curves in Excel worksheet (SCEW) has been developed for easy creation of survival curves directly in Excel worksheets. The algorithm has been integrated in the form of Excel add-in for easy installation and usage. The program is based on modification of frequency data for binary break-up using the spreadsheet formula functions whereas a macro subroutine automates the creation of survival curves. The advantages of this program are simple data input, minimal procedural steps and the creation of survival curves in the familiar confines of Excel.

    The programs diffused by the mass media are not adapted to rural populations; they have the disadvantage of a cultural domination as they diffuse urban, occidental values. Light medias are flexible, inexpensive, easy to use, and as such more adapted to the budget and to the lack of qualified personnel in the developing countries. Their diffusion is limited to small geographical areas, they can use local languages and thus adapt themselves to the ethnic and linguistic differences in each country. The light media are very suitable for nonformal education in rural areas. Light medias are good tools for dialogue and allow the population to react and hold group discussions. Light medias make community intervention possible, allowing the peasants to take part in the production of documents concerning their life conditions. This starts the process of critical autoobservation and when possible, a dialogue between the population and the administration. Unfortunately, the light media equipment tends to be built by specialists who fail to consult the populations. International experts and foreign technicians are in charge of designing and production. However the collaboration of the peasants to the audio-visual production can be considered, as shown by the example of Guatemala. An other problem is the technological dependence. The lack of qualified national personnel in electronics makes it necessary to use the services of foreign specialists. Despite these limitations, light medias help social change in a long term, and the progressive exploration of the possibilities offered by the light medias will continue.

    Public interest in astronomy content is moving from mere consumption to full interaction. With the introduction of services such as Twitter, Facebook, and YouTube, audiences are eager to engage directly with content - and its creators - in more personal ways. Wikipedia is estimated to represent 100 million hours of accumulated human thought, time spent on research, discussion, and collection of information and ideas. Sites are utilizing this "social surplus" and engaging audiences to spend their free time immersed in collaboration and communication. In 2007, the Astrophysics Science Division at NASA Goddard Space Flight Center began Blueshift, a podcasting effort to provide listeners with a "backstage pass" to what's happening within the division. After focus group reviews, this effort was re-launched as part of a larger new media effort to share how and why we do science. Each episode is a cornerstone for various means of engagement, including supporting content in blogs and Twitter. We seek to engage listeners as contributors and collaborators, sharing ideas and steering the focus of future content. As we seek to build upon the interest generated during the International Year of Astronomy, we are interested in experimenting with these new forms of interaction and assessing their impacts.

    This article was based on an analysis of three hundred articles from mainstream Brazilian periodicals over a period of eighteen months, beginning with the announcement of the Dolly case in February 1997. There were two main objectives: to outline the moral constants in the press associated with the possibility of cloning human beings and to identify some of the moral assumptions concerning scientific research with non-human animals that were published carelessly by the media. The authors conclude that there was a haphazard spread of fear concerning the cloning of human beings rather than an ethical debate on the issue, and that there is a serious gap between bioethical reflections and the Brazilian media.

  16. SETI and the Media

    2004-06-01

    Of all the research areas of modern discovery science, few attract more attention than the search for extraterrestrial intelligence. This is partially due to the fact that SETI is accessible, since the public can readily understand the goals of the research. The man in the street also finds SETI particularly exciting, a fact reflected by the ubiquitous presence of extraterrestrials in popular culture. The media interact with SETI in three areas: (1) reporting on research efforts, (2) being the principal conduit of information in case of a SETI detection, and (3) linking the subject deliberately or otherwise to the many stories of alien visitation. In this paper we will discuss the way science meets the media, and how and whether this often dicey relationship might serve to raise the general level of science literacy.

    Many knowledges on the mental disease that the community possesses are turning out of information disclosed from the media. It's common in the press to connect actions of violence and murders to the mental diseases. For this reason, the reader is induced to infer that murders and other violent actions are more frequent in people who have suffered from mentally ill, than in the general population. The mystifying impression provided by media accrues from the fact that these reports are rarely compensated from positive reports. Objective of the present study is to characterize the type of information concerning mental illness diffused from the local daily paper "Giornale di Brescia" in the year 2001. The results show that many articles connote negatively the mental disease. The journalistic sensationalism, denounced facing the speech of the prejudgment in the comparisons of the mentally ill people, seems to still remain, in the considered year of publication, one unchanging tendency.

    The paper summarizes the results of investigations performed to obtain deep 3-D holograms with 102 i0 mkm physical thickness allowing the postexposure amplification and the a posteriori changing of the grating parameters. This aim has been achieved by developing heterogeneous systems on the basis of porous glass with light-sensitive compositions introduced into it. 1. INTRODUCTION. LIGHT-SENSITIVE MEDIA FOR 3-D HOLOGRAMS RECORDING. The 3-D holograms have many useful properties: very high diffraction efficiency angular and spectral selectivity but low level of noise. It shoud be noted that in this case deep 3-D holograms are dealt with whose physical thickness is as high as 102 -i mkm. Such hologram recording is usually done using homogeneous light-sensitive media for example dyed acid-halide and electrooptical crystals photochrome glass photostructurized polimer compositions and so on. The nature of photophisical and photochemical processes responsible for the light sensitivity of these materials exclude the possibility of post-exposure treatment. This does not allow to enhance the recorded holograms and considerably hampers their fixing or makes it practically impossible. The object of our work is to create the media which are quite suitable for two-stage processes of the deep hologram formation with post-exposure processing. Such material must satisfy the following requirements: a)they must have high permeability for the developing substances in order to make the development duration suitable for practical applications b)they must be shrinkproof to prevent deformation of the

    Program developers in India's mass media are turning to the discipline of child development to increase their sensitivity to the special needs and capacities of child audiences. Children are particularly susceptible to having their thoughts, feelings, values, and behavior influenced by media programming. In India, radio is the medium with the greatest opportunity to communicate with children and programming for young people includes educational material, variety programs, quiz shows, drama, and live programs in which children participate. The 1st Children's Film Festival was held in India in 1952 and India participates in the International Center of Films for Children and Young People. Television enjoys popularity among children, illiterates, and the poor, but its potential to create social awareness, change behaviors, and raise the standard of living of the Indian people has not been fully realized. Drama is less able to reach large numbers of children, but offers children the opportunity to participate directly in the portrayal of different characters and emotions. Recently, the tradition of puppetry has been rivived and integrated into India's school curriculum. Finally, India is taking steps to expand the number of books available to children and the Government has established 2 trusts to support the publication of children's literature. Regardless of the form of media, it is important for parents to play a role in ensuring the appropriateness of the programming for the child and processing its content.

    Chronic media multitasking is quickly becoming ubiquitous, although processing multiple incoming streams of information is considered a challenge for human cognition. A series of experiments addressed whether there are systematic differences in information processing styles between chronically heavy and light media multitaskers. A trait media multitasking index was developed to identify groups of heavy and light media multitaskers. These two groups were then compared along established cognitive control dimensions. Results showed that heavy media multitaskers are more susceptible to interference from irrelevant environmental stimuli and from irrelevant representations in memory. This led to the surprising result that heavy media multitaskers performed worse on a test of task-switching ability, likely due to reduced ability to filter out interference from the irrelevant task set. These results demonstrate that media multitasking, a rapidly growing societal trend, is associated with a distinct approach to fundamental information processing.

    In this paper, we present a compact, inexpensive, and easy-to-use optical chip interferometer based on the telecom integrated waveguide technology. The measurement evaluation is focused on the resolution and the noise level of the sensor. The power spectral density of 100 fm Hz-1/2 @ 10 kHz is reached in static conditions. The same level is obtained with the standard Allan deviation for both short and long term measurements. Dynamic performances are also evaluated with sub-nanometer measurements made with piezoelectric systems. The potential bandwidth of the sensor is very high and is currently only limited by electronics (250 kHz).

    We have designed a simple, inexpensive, easy-to-build and operate apparatus for measuring blood oxygen content. The galvanic oxygen cell (fuel cell) requires as little as 1 microliter of blood and has a measuring time of 1-3 min. It is well suited for measuring oxygen content in fluids low in oxygen inasmuch as the sensitivity of the instrument is variable. Either air or water (at a known temperature and oxygen tension) can be used for calibration. No significant differences in blood oxygen content measured with our cell or the Van Slyke manometric method were found.

    We report the liquid crystal (LC) alignment surface which has two orthogonal easy axes induced by a unidirectional rubbing treatment. When the photoreactive polymer with chalconyl sidechains is irradiated with nonpolarized UV light and subsequently rubbed with a cloth, LCs align parallel and perpendicular to the rubbing direction on the UV irradiated and nonirradiated surfaces, respectively. The polarized UV absorption of the polymer and the sign of the dichroism are measured to explain the alignment mechanism. The micropatterning of the LC alignment is successfully demonstrated through the simple process using a photomask and nonpolarized UV irradiation technique.

Second, tribal women hold lower positions than men in all social, political, and ritual matters, and this contributes to their vulnerability during the hunt for scapegoats. This article also highlights the roles that rumors play during manipulation of witchcraft accusations to gather support for witch hunts.

    We investigate the gap in excitation spectrum of one-dimensional S=1 ferro- and antiferromagnets with easy-plane single-ion anisotropy. The self-consistent modification of Hubbard operators approach which enables to account single-site term exactly is used. For antiferromagnetic model we found Haldane phase that exists up to point D=4 J (where D is anisotropy parameter, J is exchange coupling), while quadrupolar phase realizes at larger values of anisotropy. Our results specify those of Golinelli et al. (Phys. Rev. B. 45 (1992) 9798), where similar model was studied. Besides the method gives gap value closer to numerical estimations than usual spin-wave theories.

The magnetic field perpendicular to the helical axis stabilizes the kink crystal state which plays a role of ''topological protectorate'' for the traveling soliton with a definite handedness. To find new soliton solution, we use the Baecklund transformation technique. It is pointed out that the traveling soliton carries the magnon density and a magnetic soliton transport may be realized.

    The study of the materials and techniques employed for wall painting, complementing the information from historical and aesthetic data, contributes to the integrated knowledge of the iconographer and his period. In the 16th century, regarding the iconography in the former Byzantine area, besides the School of Crete and Francos Catelanos and his school, a third artistic personality who also created his own school, Onoufrios, appeared in central Albania and expanded his activity as a painter to northern Greece as well as nearby areas, such as Ohrid. Inscriptions documenting the works of Onoufrios are found in some of the churches that he decorated with wall paintings: “St. Apostles” (1547) Kastoria Greece, “St. Nicolas” Shelcan Albania, “St. Paraskevi” (1554), Valsh Albania, while are attributed to him the church of “St. Theodores” in Berati, Albania (before 1547) and others. He is one of the best icon painters of the whole Balkan region, and the best painter that has ever worked in Albanian territory. Onoufrios managed to combine the local painting tradition with the best tradition of the eastern (Paleologian) and western (Italian) schools, resulting in a realistic and natural depiction. He is the creator of the “Berati School” that expanded to other parts of the peninsula. His individual character can be distinguished in the work of his students: his son Nikolaos (who inherited his style in painting), Onoufrios from Cyprus, etc. Based on careful observations, we extracted number of paint samples from wall paintings of three of the above mentioned churches. Ground and paint layers were examined using micro-FTIR, Optical Microscopy, TXRF and SEM-EDS, to characterize materials and methods used by the artist to create these works. Our findings in each church are discussed and compared with the others in order to understand how and with what material and resources the painter worked and how he developed his technique.

  3. Poromechanics of microporous media

    NASA Astrophysics Data System (ADS)

    Brochard, L.; Vandamme, M.; Pellenq, R. J.-M.

    2012-04-01

    Microporous media, i.e., porous media made of pores with a nanometer size, are important for a variety of applications, for instance for sequestration of carbon dioxide in coal, or for storage of hydrogen in metal-organic frameworks. In a pore of nanometer size, fluid molecules are not in their bulk state anymore since they interact with the atoms of the solid: they are said to be in an adsorbed state. For such microporous media, conventional poromechanics breaks down. In this work we derive poroelastic constitutive equations which are valid for a generic porous medium, i.e., even for a porous medium with pores of nanometer size. The complete determination of the poromechanical behavior of a microporous medium requires knowing how the amount of fluid adsorbed depends on both the fluid bulk pressure and the strain of the medium. The derived constitutive equations are validated with the help of molecular simulations on one-dimensional microporous media. Even when a microporous medium behaves linearly in the absence of any fluid (i.e., its bulk modulus does not depend on strain), we show that fluid adsorption can induce non-linear behavior (i.e., its drained bulk modulus can then depend significantly on strain). We also show that adsorption can lead to an apparent Biot coefficient of the microporous medium greater than unity or smaller than zero. The poromechanical response of a microporous medium to adsorption significantly depends on the pore size distribution. Indeed, the commensurability (i.e., the ratio of the size of the pores to that of the fluid molecules) proves to play a major role. For a one-dimensional model of micropores with a variety of pore sizes, molecular simulations show that the amount of adsorbed fluid depends linearly on the strain of the medium. We derive linearized constitutive equations which are valid when such a linear dependence of the adsorbed amount of fluid on the strain is observed. As an application, the case of methane and coal is

    Cell culture media are very complex chemical mixtures that are one of the most important aspects in biopharmaceutical manufacturing. The complex composition of many media leads to materials that are inherently unstable and of particular concern, is media photo-damage which can adversely affect cell culture performance. This can be significant particularly with small scale transparent bioreactors and media containers are used for process development or research. Chromatographic and/or mass spectrometry based analyses are often time-consuming and expensive for routine high-throughput media analysis particularly during scale up or development processes. Fluorescence excitation-emission matrix (EEM) spectroscopy combined with multi-way chemometrics is a robust methodology applicable for the analysis of raw materials, media, and bioprocess broths. Here we demonstrate how EEM spectroscopy was used for the rapid, quantitative analysis of media degradation caused by ambient visible light exposure. The primary degradation pathways involve riboflavin (leading to the formation of lumichrome, LmC) which also causes photo-sensitised degradation of tryptophan, which was validated using high pressure liquid chromatography (HPLC) measurements. The use of PARallel FACtor analysis (PARAFAC), multivariate curve resolution (MCR), and N-way partial least squares (NPLS) enabled the rapid and easy monitoring of the compositional changes in tryptophan (Trp), tyrosine (Tyr), and riboflavin (Rf) concentration caused by ambient light exposure. Excellent agreement between HPLC and EEM methods was found for the change in Trp, Rf, and LmC concentrations. PMID:24356227

    This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication.

    Interlayer exchange coupling between layers with perpendicular and easy-plane magnetic anisotropies separated by a non-magnetic spacer is studied using ferromagnetic resonance. The samples consist of a Co/Ni multilayer with perpendicular magnetic anisotropy and a CoFeB layer with easy-plane anisotropy separated by a variable thickness Ru layer. At a fixed frequency, we show that there is an avoided crossing of layer ferromagnetic resonance modes providing direct evidence for interlayer coupling. The mode dispersions for different Ru thicknesses are fit to a Heisenberg-type model to determine the interlayer exchange coupling strength and layer properties. The resulting interlayer exchange coupling varies continuously from antiferromagnetic to ferromagnetic as a function of the Ru interlayer thickness. These results show that the magnetic layer single domain ground state consists of magnetizations that can be significantly canted with respect to the layer planes and the canting can be tuned by varying the Ru thickness and the layer magnetic characteristics, a capability of interest for applications in spin-transfer torque devices.

    Spin–orbit torque, a torque brought about by in-plane current via the spin–orbit interactions in heavy-metal/ferromagnet nanostructures, provides a new pathway to switch the magnetization direction. Although there are many recent studies, they all build on one of two structures that have the easy axis of a nanomagnet lying orthogonal to the current, that is, along the z or y axes. Here, we present a new structure with the third geometry, that is, with the easy axis collinear with the current (along the x axis). We fabricate a three-terminal device with a Ta/CoFeB/MgO-based stack and demonstrate the switching operation driven by the spin–orbit torque due to Ta with a negative spin Hall angle. Comparisons with different geometries highlight the previously unknown mechanisms of spin–orbit torque switching. Our work offers a new avenue for exploring the physics of spin–orbit torque switching and its application to spintronics devices.

This guide builds on the principles of web usability and adds to existing best practices by providing research-based strategies for writing and designing health websites especially for users with limited literacy and health literacy skills. This guide synthesizes years of lessons learned from Office of Disease Prevention and Health Promotion's original research with hundreds of web users, experience with revising the healthfinder.gov, as well as strategies supported by the Research-Based Web Design and Usability Guidelines (Usability.gov). In the United States, roughly one third of adults have limited literacy skills, yet far more (as many as 90%) have limited health literacy skills, meaning they have trouble understanding complex health information. This how-to guide is timely and developed with the aim of creating easy-to-use health websites to reach as many web users as possible, especially those with limited literacy and health literacy skills.

    The magnetic, magnetoelectric, and magnetoelastic properties of RFe{sub 3}(BO{sub 3}){sub 4} ferroborates are studied. The measurement of the field dependences of the magnetoelectric polarization along the a axis in holmium ferroborate and in the mixed composition Ho{sub 0.5}Sm{sub 0.5}Fe{sub 3}(BO{sub 3}){sub 4} revealed the following dependences for easy-plane ferroborates: (a) the longitudinal and transverse magnetoelectric effects have the opposite signs and (b) magnetically induced polarization changes its sign in a field close to the field of exchange between rare-earth and iron ions. These dependences agree well with theoretical predictions based on the symmetry of the compounds. The relatively low f-d exchange field in holmium ferroborate (about 20 kOe), which magnetizes the rare-earth subsystem, causes smaller polarization jumps (about 30 {mu}C/m{sup 2}) in fields lower than 10 kOe as compared to the jumps in other easy-plane ferroborates (R = Sm, Nd). The increase in the electric polarization induced in HoFe{sub 3}(BO{sub 3}){sub 4} in magnetic fields higher than 100 kOe (200-300 {mu}C/m{sup 2}) is found to be significantly smaller than in neodymium ferroborate, which indicates a substantial dependence of the magnetoelectric effects on the electronic structure of a rare-earth ion.

  12. Distortion Analysis Toolkit—A Software Tool for Easy Analysis of Nonlinear Audio Systems

    2010-12-01

    Several audio effects devices deliberately add nonlinear distortion to the processed signal in order to create a desired sound. When creating virtual analog models of nonlinearly distorting devices, it would be very useful to carefully analyze the type of distortion, so that the model could be made as realistic as possible. While traditional system analysis tools such as the frequency response give detailed information on the operation of linear and time-invariant systems, they are less useful for analyzing nonlinear devices. Furthermore, although there do exist separate algorithms for nonlinear distortion analysis, there is currently no unified, easy-to-use tool for rapid analysis of distorting audio systems. This paper offers a remedy by introducing a new software tool for easy analysis of distorting effects. A comparison between a well-known guitar tube amplifier and two commercial software simulations is presented as a case study. This freely available software is written in Matlab language, but the analysis tool can also run as a standalone program, so the user does not need to have Matlab installed in order to perform the analysis.

    Project EASI is the first implemented Complementary Experiment within the AlpArray program (http://www.alparray.ethz.ch) and stands for Eastern Alpine Seismic Investigation. The seismological field experiment ran for one year, from Summer 2014 to Summer 2015, composed of 55 broadband stations deployed in zig-zag in a ca. 15 km-wide band along longitude 13.35°E, spanning 540 km from the Czech-German border to the Adriatic Sea. Here we present first results using P-to-S converted waves from teleseismic distances. The variation of Moho depth along the profile is analyzed and linked to the two colliding plates, Adria and Europe, as well as to the overlying lithospheric blocks of the Bohemian Massif. The suggested Moho "hole" between Adria and Europe is characterized. We investigate the anisotropic nature of the lower crust of both plates. We conclude on the structural relationship of Adria and Europe at the crustal level, and infer their respective positions at depth. Furthermore, preliminary S-to-P conversions illuminating the lithosphere-asthenosphere boundary test the significant depth variation of this boundary along the EASI transect and complement our receiver function study.

    To develop a novel sodium fusidate-loaded film-forming hydrogel (FFH) for easy application and excellent wound healing, various FFH formulations and corresponding FFH dried films were prepared with drug, polyvinylalcohol (PVA), polyvinylpyrrolidone (PVP), propylene glycol, ethanol and water, and their film forming times, mechanical properties, drug release, in vivo wound healing in rat and histopathology were assessed. The sodium fusidate-loaded FFH composed of sodium fusidate/PVP/PVA/propylene glycol/ethanol/water at the weight ratio of 1/2/12/3/8/74 could form a corresponding dried film in the wound sites promptly due to fast film-forming time of about 4 min. This FFH showed an appropriate hardness and adhesiveness. Furthermore, this corresponding dried film provided an excellent flexibility and elasticity, and gave relatively high drug release. As compared with the sodium fusidate-loaded commercial product, it significantly improved excision and infection wound healing in rats. This FFH was stable at 45°C for at least 6 months. Therefore, this novel sodium fusidate-loaded FFH would be an effective pharmaceutical product with easy application for the treatment of wounds.

    Purpose: To build a simple model to teach and validate non-pulsatile and pulsatile flow quantification in ultrasound. Materials and Methods: The setting consists of the following connected components: (1) medical syringe pump producing an adjustable constant flow (ml/min), (2) modulator modifying constant flow to a reproducible pulsatile flow, (3) water tank containing a diagonal running silicone tube (0.5 mm inner diameter), and (4) a fixated ultrasound probe (L9 Linear Array 9 MHz, GE Logiq E9) measuring the flow inside the tube. Commercially available microbubbles suspended with physiological saline solution were used for ultrasonic visibility. Spectral Doppler of different flow profiles is performed. Results: The syringe pump produces an adjustable, constant flow and serves as the reference standard. The filling volume of the tube system is 1.2 ml. Microbubbles are very well detected by ultrasound and can be used as an easy and clean blood mimicking substance. The modulator generates different physiological and pathological flow profiles. Velocities are similar to those found within human blood vessels. Thus, it is possible to train and validate flow measurements in ultrasound. Conclusion: The model produces non-pulsatile and various pulsatile flow profiles and allows validation of flow measurements. The compact size permits easy and economic setup for flow measurements in research, skills lab and continuing education.

    Purpose Single-site laparoscopic surgery has become increasingly common. We herein report an easy and low-cost thoracic trocar technique (TTT) for these types of procedures and recommend the simpler name "transumbilical scarless surgery" (TUSS) to minimize confusion in nomenclature. Methods We retrospectively reviewed patients who underwent TUSS by TTT using a thoracic trocar and surgical glove in our hospital between November 2011 and November 2012. Operating time, postoperative stay, and complications were detailed. Results A total of 101 TUSS by TTT were successfully performed, comprising appendectomy (n = 63), ovarian cyst excision (n = 7), splenectomy (n = 5), nephroureterectomy (n = 5), orchidopexy (n = 4), pyeloplasty (n = 3), nephrolithotomy (n = 2), orchiectomy (n = 2), varicocelectomy (n = 2), lymphangioma excision (n = 2), ureterectomy (n = 1), Morgagni diaphragmatic hernia repair (n = 1), ovarian detorsion (n = 1), antegrade continence enema (n = 1), intestinal resection anastomosis (n = 1), and intestinal duplication excision (n = 1). Kirschner wires were used for some organ traction. Nine patients required an additional port, but no major complications occurred. The postoperative stay (mean ± standard deviation) was 3.2 ± 1.4 days, and operating time was 58.9 ± 38.3 minutes. Conclusion We recommend the simpler name of TUSS to minimize confusion in nomenclature for all transumbilical single-incision laparoendoscopic surgeries. TTT is an easy and low-cost TUSS technique.

    Anaerobic bacteria, Peptostrepotococcus intermedius and Propionibacterium acnes, were found in mixed culture specimens from four to ten tested cases of chronic secretory otitis media. These anaerobic bacteria were in a mixed infection flora with aerobic bacteria most often Staphylococcus epidermidis and Cornybacterium sp. which do not fit any established species. The findings of anaerobic bacteria in otitis media is consistent with the sporadic report of the involvement of anaerobic bacteria in otitis media in the literature since 1898.

    Introduction Chronic suppurative otitis media (CSOM) is a common cause of hearing impairment and disability. Occasionally it can lead to fatal intracranial infections and acute mastoiditis, especially in developing countries. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for chronic suppurative otitis media in adults and in children? What are the effects of treatments for cholesteatoma in adults and in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 51 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: topical ear cleansing, surgery for cholesteatoma, systemic antibiotics, topical antibiotics, topical antibiotics plus topical corticosteroids, topical antiseptics, topical corticosteroids, tympanoplasty (with or without mastoidectomy).

Additionally, several models of information processing are presented which offer both a cognitive and affective model of processing communications. Finally, the article points to the need for future research to analyze the cases and implications of media's impact on adolescents when media serve as a primary, rather than a secondary, source of socialization.

  8. Fractures in anisotropic media

    NASA Astrophysics Data System (ADS)

    Shao, Siyi

    Rocks may be composed of layers and contain fracture sets that cause the hydraulic, mechanical and seismic properties of a rock to be anisotropic. Coexisting fractures and layers in rock give rise to competing mechanisms of anisotropy. For example: (1) at low fracture stiffness, apparent shear-wave anisotropy induced by matrix layering can be masked or enhanced by the presence of a fracture, depending on the fracture orientation with respect to layering, and (2) compressional-wave guided modes generated by parallel fractures can also mask the presence of matrix layerings for particular fracture orientations and fracture specific stiffness. This report focuses on two anisotropic sources that are widely encountered in rock engineering: fractures (mechanical discontinuity) and matrix layering (impedance discontinuity), by investigating: (1) matrix property characterization, i.e., to determine elastic constants in anisotropic solids, (2) interface wave behavior in single-fractured anisotropic media, (3) compressional wave guided modes in parallel-fractured anisotropic media (single fracture orientation) and (4) the elastic response of orthogonal fracture networks. Elastic constants of a medium are required to understand and quantify wave propagation in anisotropic media but are affected by fractures and matrix properties. Experimental observations and analytical analysis demonstrate that behaviors of both fracture interface waves and compressional-wave guided modes for fractures in anisotropic media, are affected by fracture specific stiffness (controlled by external stresses), signal frequency and relative orientation between layerings in the matrix and fractures. A fractured layered medium exhibits: (1) fracture-dominated anisotropy when the fractures are weakly coupled; (2) isotropic behavior when fractures delay waves that are usually fast in a layered medium; and (3) matrix-dominated anisotropy when the fractures are closed and no longer delay the signal.

    We describe Ostracism Online, a novel, social media-based ostracism paradigm designed to (1) keep social interaction experimentally controlled, (2) provide researchers with the flexibility to manipulate the properties of the social situation to fit their research purposes, (3) be suitable for online data collection, (4) be convenient for studying subsequent within-group behavior, and (5) be ecologically valid. After collecting data online, we compared the Ostracism Online paradigm with the Cyberball paradigm (Williams & Jarvis Behavior Research Methods, 38, 174-180, 2006) on need-threat and mood questionnaire scores (van Beest & Williams Journal of Personality and Social Psychology 91, 918-928, 2006). We also examined whether ostracized targets of either paradigm would be more likely to conform to their group members than if they had been included. Using a Bayesian analysis of variance to examine the individual effects of the different paradigms and to compare these effects across paradigms, we found analogous effects on need-threat and mood. Perhaps because we examined conformity to the ostracizers (rather than neutral sources), neither paradigm showed effects of ostracism on conformity. We conclude that Ostracism Online is a cost-effective, easy to use, and ecologically valid research tool for studying the psychological and behavioral effects of ostracism.

  20. A quick and easy method to identify bacteria by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry.

    Concerns with water quality have increased in recent years, in part due to the more frequent contamination of water by pathogens like E. coli and L. pneumophila. Current methods for the typing of bacteria in water samples are based on culture of samples on specific media. These techniques are time-consuming, subject to the impact of interferents and do not totally meet all the requirements of prevention. There is a need for accurate and rapid identification of these microorganisms. This report deals with the detection of bacteria, more precisely of Legionella spp., and the development of an analytical strategy for a rapid and unambiguous identification of these pathogens in water from diverse origins. Therefore, a protein mass mapping using matrix-assisted laser desorption/ionisation mass spectrometry (MALDI MS) of whole bacteria combined with a home-made database of bacteria spectra is applied. A large variety of different bacteria and microorganisms is used to approach the actual composition of samples with numerous interferents. The objective is to propose a universal method for sampling preparation before MALDI MS analysis and optimised spectrometric conditions for reproducible intense peaks. Several experimental factors known to influence signal quality such as time and media of culture have been studied. The proposed method gives promising results for a sure differentiation of Legionella species and subspecies and a rapid identification of bacteria which are the most dangerous or difficult to eradicate. This method is easy to perform with an excellent reproducibility. The analytical protocol and the corresponding database were validated on samples from different origins (cooling tower, plumbing hot water). PMID:20049880

    2003-10-10

    The modifications to the holodiagram concept to describe free propagation (the extraordinary ray) inside birefringent materials are described. Holodiagrams are graphs showing the loci where the sum or the difference in the optical path from a generic point to two foci is the same. The holodiagrams obtained in this way give the shape of the surfaces that satisfy Fermat's principle, conjugate by reflection of one focus into the other, and represent the interference fringes obtained if both points are coherent sources. The reflection law in birefringent media is investigated in relation to this diagram. One direction for the optical axis is considered: parallel to the line joining the source and the observation point. Quartz-type and calcite-type crystals are studied. PMID:14577535

    Acne is a frequent disease with a strong impact upon quality of life. The most effective treatment of severe acne is isotretinoin. Cases of suicid have been reported during isotretinoin treatments in adolescents and were mediatised. Now a day, the link between isotretinoin intake and psychiatric troubles is not established at populational level. The pressure of public and medias led the French Drug Agency to send a letter to health professionals to summarize the scientific question. An explanative video is on line on the website of the French Society of Dermatology www.dermato-info.fr. This video summarizes the state of the art concerning the context of isotretinoin for public, dermatologists and other physicians To summarize isotretinoin is the drug for severe acne in case of failure of first line classical treatment. Dermatologists must stay the first line prescribers reminding that adolescence is a fragile period.

    The fieldwork associated with Task 1 (Baseline Assessment) was completed this quarter. Detailed cyclone inspections completed at all but one plant during maintenance shifts. Analysis of the test samples is also currently underway in Task 4 (Sample Analysis). A Draft Recommendation was prepared for the management at each test site in Task 2 (Circuit Modification). All required procurements were completed. Density tracers were manufactured and tested for quality control purposes. Special sampling tools were also purchased and/or fabricated for each plant site. The preliminary experimental data show that the partitioning performance for all seven HMC circuits was generally good. This was attributed to well-maintained cyclones and good operating practices. However, the density tracers detected that most circuits suffered from poor control of media cutpoint. These problems were attributed to poor x-ray calibration and improper manual density measurements. These conclusions will be validated after the analyses of the composite samples have been completed.

    A 2.8-liter tube-shaped combustion vessel was constructed to study flame propagation and quenching in porous media. For this experiment, hydrogen-air flames propagating horizontally into abed of 6 mm diameter glass beads were studied. Measurements of pressure and temperature along the length of the tube were used to observe flame propagation of quenching. The critical hydrogen concentration for Hz-air mixtures was found to be 11.5%, corresponding to a critical Peclet number of Pe* = 37. This value is substantially less than the value of Pe* = 65 quoted in the literature, for example Babkin et al. (1991). It is hypothesized that buoyancy and a dependence of Pe on the Lewis number account for the discrepancy between these two results.

    Acute otitis media (AOM) is a common problem facing general practitioners, paediatricians and otolaryngologists. This article reviews the aetiopathogenesis, epidemiology, presentation, natural history, complications and management of AOM. The literature was reviewed by using the PubMed search engine and entering a combination of terms including 'AOM', 'epidemiology' and 'management'. Relevant articles were identified and examined for content. What is the take-home message? AOM is a very common problem affecting the majority of children at least once and places a large burden on health care systems throughout the world. Although symptomatic relief is often enough for most children, more severe and protracted cases require treatment with antibiotics, especially in younger children. PMID:25913598

    The test data obtained from the Baseline Assessment that compares the performance of the density traces to that of different sizes of coal particles is now complete. The experimental results show that the tracer data can indeed be used to accurately predict HMC performance. The following conclusions were drawn: (i) the tracer curve is slightly sharper than curve for coarsest size fraction of coal (probably due to the greater resolution of the tracer technique), (ii) the Ep increases with decreasing coal particle size, and (iii) the Ep values are not excessively large for the well-maintained HMC circuits. The major problems discovered were associated with improper apex-to-vortex finder ratios and particle hang-up due to media segregation. Only one plant yielded test data that were typical of a fully optimized level of performance.

    Highly crosslinked monolithic porous polymer materials for chromatographic applications. By using solvent compositions that provide not only for polymerization of acrylate monomers in such a fashion that a porous polymer network is formed prior to phase separation but also for exchanging the polymerization solvent for a running buffer using electroosmotic flow, the need for high pressure purging is eliminated. The polymer materials have been shown to be an effective capillary electrochromatographic separations medium at lower field strengths than conventional polymer media. Further, because of their highly crosslinked nature these polymer materials are structurally stable in a wide range of organic and aqueous solvents and over a pH range of 2-12.

    In this study, we developed an integrated, low-cost microfluidic cell culture system that is easy to use. This system consists of a disposable polystyrene microchip, a polytetrafluoroethylene valve, an air bubble trap, and an indium tin oxide temperature controller. Valve pressure resistance was validated with a manometer to be 3 MPa. The trap protected against bubble contamination. The temperature controller enabled the culture of Macaca mulatta RF/6A 135 vascular endothelial cells, which are difficult to culture in glass microchips, without a CO2 incubator. We determined the optimal coating conditions for these cells and were able to achieve stable, confluent culture within 1 week. This practical system is suitable for low-cost screening and has potential applications as circulatory cell culture systems and research platforms in cell biology. PMID:26960617

    2003-07-01

    An easy wafer level transfer process for fabrication of electrostatically actuated structures such as bulk micromachined motors or cantilevers is described. The actual structures were fabricated by dry etching of a donor wafer, transferred to a handling wafer using room temperature oxygen plasma assisted bonding and then revealed through etchback of the donor wafer. Notching during the dry etch was avoided since there is no need for a buried oxide etch stop layer. Etch depth differences after the dry etch were eliminated in the etchback step. The process was used to fabricate MEMS demonstrators in the form of micro pinball games and microelectromechanical wobble motors. This process is a low cost alternative to using SOI wafers and it also circumvents some of the problems of deep dry etching that arise when using buried etch stop layers as in the case of SOI wafers. Another advantage of using SOI wafers is that double-sided micromachining becomes less complicated.

    The Usable Smart Environment project (USE) aims at designing easy-to-use, highly functional, next-generation conference rooms. Our first design prototype focuses on creating a “no wizards” room for an American executive; that is, a room the executive could walk into and use by himself, without help from a technologist. A key idea in the USE framework is that customization is one of the best ways to create a smooth user experience. As the system needs to fit both with the personal leadership style of the executive and the corporation’s meeting culture, we began the design process by exploring the work flow in and around meetings attended by the executive.

    A fast and easy tool to locate unit-cell matches in the PDB is described. When embarking upon X-ray diffraction data collection from a potentially novel macromolecular crystal form, it can be useful to ascertain whether the measured data reflect a crystal form that is already recorded in the Protein Data Bank and, if so, whether it is part of a large family of related structures. Providing such information to crystallographers conveniently and quickly, as soon as the first images have been recorded and the unit cell characterized at an X-ray beamline, has the potential to save time and effort as well as pointing to possible search models for molecular replacement. Given an input unit cell, and optionally a space group, Nearest-cell rapidly scans the Protein Data Bank and retrieves near-matches.

    The ability of gecko lizards to adhere to a vertical solid surface comes from their remarkable feet with aligned microscopic elastic hairs. By using carbon nanotube arrays that are dominated by a straight body segment but with curly entangled top, we have created gecko-foot mimetic dry adhesives that show macroscopic adhesive forces of ~100 newtons per square centimeter, almost 10 times that of a gecko foot, and a much stronger shear adhesion force than the normal adhesion force, to ensure strong binding along the shear direction and easy lifting in the normal direction. This anisotropic force distribution is due to the shear-induced alignments of the curly segments of the nanotubes. The mimetic adhesives can be alternatively binding-on and lifting-off over various substrates for simulating the walking of a living gecko.

    In this study, 41 asymptomatic subjects (22 men and 19 women, 20 to 60 years of age) were enrolled. The PWV was measured both by dual-channel PPG (PWV-DVP) and by the proposed PWV instrument, Pulse Wave Velocity by Digital Volume Pulse Easy (PWV-DVPE). The developed system recorded digital volume pulse simultaneously from both the finger and ear. Time of pulse transition was measured on the time delay difference between two digital volume pulses. The PWV was calculated by dividing the distance between finger and ear by that of transit time. PWV-DVPE's capability of precise self-monitoring arterial stiffness is being proven in this study. In home care area, only few minutes is needed for self arterial stiffness assessment. Therefore, early self-monitoring of cardio-vascular dys-function and arterial stiffness is easily and effectively achieved. PMID:18003349

    In this study, we present an easy way to create layered-nanoplatelets with well-defined geometry by controlling the cracking process of nanostructured multilayers. The geometrical dimension of layered-nanoplatelets is determined by the multilayer intrinsic size, the total strain, and the elastic mismatch between the substrate and multilayers, which was analyzed by statistical approach. Fracture behaviors characterized by critical strain to nucleate microcrack, fracture toughness, and evolution of fragment width were also studied for nanostructured Cu/Cr multilayers with modulation period (λ) spanning from of 5 to 250 nm and were quantified based on linear elastic theory and shear-lag theory. An optimal modulation period seems to be likely favorable for maximizing the ductility, strength, and fracture toughness of the nanolayered materials.

    In this work, a calibration phantom based on an electrical resistor heating rod is presented, which creates a temperature distribution similar to those in typical HIFU fields (diameter ˜2 mm, heating rate ˜10 K/s). The temperature distribution is measured first with a calibrated reference device and then with MR thermometry. Equal conditions for both measurements can be ensured by monitoring the voltage and current across the resistor during the heating. From the comparison of both measurements, the accuracy of the MR measurement can be assessed. The calibration phantom is MR compatible, and it has high reproducibility and low production costs. A wide variety of possible heating sequences can be employed and the phantom has a compact and easy setup. Thus, it can be used to quickly verify the results from newly developed MR thermometry sequences as well as to evaluate the uncertainties of existing sequences.

    2009-09-01

    A new rapid method for titrating baculovirus stocks has been developed using a novel cell line Sf-9 Easy Titer (Sf-9ET). The Sf-9ET cell line has been transfected with plasmid DNA containing the enhanced green fluorescent protein (eGFP) gene under the control of the baculovirus polyhedrin promoter. When used in the titration assay, the Sf-9ET cells turn green when they are infected with baculovirus due to the activation of the polyhedrin promoter/eGFP complex by baculovirus gene products expressed during the infection. Using a 96-well plate format end-point dilution assay, baculovirus titers can be determined in three days using a fluorescence microscope.

    We present a concept and prototype of a memory element based on current driven magneto-impedance (MI) effect that stores the binary data (0, 1) as the orientation of the magnetization. The magnetization orientation in the surface layer with tilted anisotropy easy axis can be switched controllably between two stable states by applying current pulses of the appropriate sign, and can be detected by sensing the impedance. We demonstrated the functioning of a non-volatile magnetic memory with a read speed performance up to and above 2 GHz. A prototype of a memory element was realized on a short piece of amorphous microwire, as this material exhibits the highest MI effect, and the required anisotropy can be quite easily obtained. Nevertheless, this concept can be extended to other materials and geometries exhibiting MI effect and possessing a required magnetic anisotropy. PMID:27782190

    2009-01-01

    Training exercises can improve perceptual sensitivities. We examined whether progressively training humans and rats to perform a difficult auditory identification task led to larger improvements than extensive training with highly similar sounds (the easy-to-hard effect). Practice improved humans’ ability to distinguish sounds regardless of the training regimen. However, progressively trained participants were more accurate and showed more generalization, despite significantly less training with the stimuli that were the most difficult to distinguish. Rats showed less capacity to improve with practice, but still benefited from progressive training. These findings indicate that transitioning from an easier to a more difficult task during training can facilitate, and in some cases may be essential for, auditory perceptual learning. The results are not predicted by an explanation that assumes interaction of generalized excitation and inhibition, but are consistent with a hierarchical account of perceptual learning in which the representational precision required to distinguish stimuli determines the mechanisms engaged during learning.

    Light-quality is extremely crucial for any light source to be used for illumination. However, a proper light-quality index is still missing although numerous electricity-driven lighting measures have been introduced since past 150 yr. We present in this communication a universal and easy-to-apply index for quantifying the quality of any given lighting source, which is based on direct comparison of its lumen spectrum with the natural light counterpart having the same color temperature. A general principle for creating high quality pseudo-natural light is accordingly derived. By using organic light-emitting diode technology, for example, daylight-style emission with a 96% natural light resemblance is obtained as a high number of organic emitters with diffused colors spanning throughout the entire visible range are employed. The same principle can be extended to other lighting technology such as light-emitting diode to generate natural light-style emission.

    2013-08-01

    The SpeechEasy is an electronic device designed to alleviate stuttering by manipulating auditory feedback via time delays and frequency shifts. Device settings (control, default, custom), ear-placement (left, right), speaking task, and cognitive variables were examined in people who stutter (PWS) (n=14) compared to controls (n=10). Among the PWS there was a significantly greater reduction in stuttering (compared to baseline) with custom device settings compared to the non-altered feedback (control) condition. Stuttering was reduced the most during reading, followed by narrative and conversation. For the conversation task, stuttering was reduced more when the device was worn in the left ear. Those individuals with a more severe stuttering rate at baseline had a greater benefit from the use of the device compared to individuals with less severe stuttering. Our results support the view that overt stuttering is associated with defective speech-language monitoring that can be influenced by manipulating auditory feedback. PMID:23712191

    Macro-aspartate transaminase (macro-AST) must be considered when the aspartate transaminase (AST) level is chronically high without any liver, cardiac, or muscle disease. Many specialized laboratory techniques have been recommended for diagnosing macro-AST, including the polyethylene glycol immune precipitate technique, which is simple. This study presents a considerably easier method based on the studies of Davidson and Watson and Castiella et al. Our method is based on the decrease in the plasma AST level after storage of the macroenzyme at 2-8 °C for 5 days, and has the advantages of low cost, reliability, and practicality at any health center. In our eight cases of macro-AST, the AST activity at day 6 had decreased by more than 50% from day 1. This method is practical for primary healthcare facilities because of its easy application and accurate results, and obviated the need for unnecessary tests after diagnosis.

    In this paper a very easy, numerically stable and computationally efficient method is presented, which allows to model and simulate a flexible robot with high precision, also under the hypothesis of large link deformations and of time-varying geometrical and physical parameters of the robot and of the end-effector. This methodology uses the same approach of the rigid robots modeling, after suitably and fictitiously subdividing each link of the robot into sublinks, rigid to the aim of the calculus of the inertia matrix and flexible to the aim of the calculus of the elastic matrix. The static and dynamic precision of the method is proved with interesting theorems. Finally, the method is used to model, control and simulate a crane with three flexible links and a varying length cable carrying a body with a variable mass.

    Context and Aim Bodily tooth movement is desirable in the field of Orthodontics and so is with molar distalization. Till date there is no such analysis available which could gauge and quantify the molar distalization and the type of tooth movement achieved, therefore one was required. Materials and Methods An OPG and Lateral cephalogram was used taking Inter orbitale plane and FH plane respectively as reference lines and the analysis was devised to measure the amount and type of tooth movement achieved in distalization of molar. Conclusion This analysis is a noble, easy and conceptual analysis to assess the type of tooth movement achieved during molar distalization and other molar movements using Lateral cephalogram and orthopantomogram.

    NASA Astrophysics Data System (ADS)

    2010-11-01

    The efficient use of complex neutron scattering instruments is often hindered by the complex nature of their operating software. This complexity exists at each experimental step: data acquisition, reduction and analysis, with each step being as important as the previous. For example, whilst command line interfaces are powerful at automated acquisition they often reduce accessibility by novice users and sometimes reduce the efficiency for advanced users. One solution to this is the development of a graphical user interface which allows the user to operate the instrument by a simple and intuitive "push button" approach. This approach was taken by the Motofit software package for analysis of multiple contrast reflectometry data. Here we describe the extension of this package to cover the data acquisition and reduction steps for the Platypus time-of-flight neutron reflectometer. Consequently, the complete operation of an instrument is integrated into a single, easy to use, program, leading to efficient instrument usage.

    Words are made of letters, and yet sometimes it is easier to identify a word than a single letter. This word superiority effect (WSE) has been observed when written stimuli are presented very briefly or degraded by visual noise. We compare performance with letters and words in three experiments, to explore the extents and limits of the WSE. Using a carefully controlled list of three letter words, we show that a WSE can be revealed in vocal reaction times even to undegraded stimuli. With a novel combination of psychophysics and mathematical modeling, we further show that the typical WSE is specifically reflected in perceptual processing speed: single words are simply processed faster than single letters. Intriguingly, when multiple stimuli are presented simultaneously, letters are perceived more easily than words, and this is reflected both in perceptual processing speed and visual short term memory (VSTM) capacity. So, even if single words come easy, there is a limit to the WSE. PMID:24027510

  8. Teaching the teachers: Making solar science education fun and easy to teach

    America is facing a quiet crisis in the scientific and technology fields. Elementary school teachers are required to teach outside their specialty area using outdated materials. Furthering this crisis, teachers don`t have time to search for their own materials. These teachers need affordable instructional materials that are fun and easy to teach. Recognizing the importance of teaching science and technology in the classroom, the Arizona Department of Commerce Energy Office developed a Solar Energy Education Packet for Teachers. Also, an implementation workshop was developed to instruct teachers on how to use the materials in the packet. In this paper, the author demonstrates the overwhelming acceptability of using solar cooking for teaching solar science principles and technology in the classroom. By taking a fun and inexpensive approach to teaching the solar science principles, they have created a program that has been embraced not only by teachers, but by students as well.

  9. Don't words come easy? A psychophysical exploration of word superiority

    Words are made of letters, and yet sometimes it is easier to identify a word than a single letter. This word superiority effect (WSE) has been observed when written stimuli are presented very briefly or degraded by visual noise. We compare performance with letters and words in three experiments, to explore the extents and limits of the WSE. Using a carefully controlled list of three letter words, we show that a WSE can be revealed in vocal reaction times even to undegraded stimuli. With a novel combination of psychophysics and mathematical modeling, we further show that the typical WSE is specifically reflected in perceptual processing speed: single words are simply processed faster than single letters. Intriguingly, when multiple stimuli are presented simultaneously, letters are perceived more easily than words, and this is reflected both in perceptual processing speed and visual short term memory (VSTM) capacity. So, even if single words come easy, there is a limit to the WSE. PMID:24027510

  10. Easy access to firearms: juveniles' risks for violent offending and violent victimization.

    Keeping firearms at home may increase personal safety but it may also increase the risk of injury. This study uses data from three waves of the National Longitudinal Study of Adolescent Health to assess the extent to which adolescents' easy access to firearms at home increases the risk of violent offending and violent victimization. Access to firearms was higher for males, Whites, and adolescents having two parents, especially fathers. Current access to firearms at home significantly increased the odds of both violent offending and violent victimization, even after controlling for prior access, prior offending, and prior victimization. This relationship persisted into early adulthood; access to firearms still significantly increased the odds of violent offending and violent victimization.

  11. Improved performance of sulfur cathode by an easy and scale-up coating strategy

    A new fabricating process for high-performance sulfur cathode is proposed. The fabricating process relies on two-step coating technique: firstly, high sulfur content slurry is coated on the current collector. After drying, the electrode is coated with another slurry composed of Super P and binder. The sulfur electrode with relatively high sulfur content/loading of 60 wt%/2 mg cm-2 discharges capacity of ∼695 mAh g-1 at 0.5 C after 100 cycling. This method is easy for industrialization and well controlled over the areal sulfur loading and mass, therefore it is efficient for fabricating high-performance Li-S batteries with high-energy density.

    We present an experimental investigation of the magnetic, electrical, and structural properties of Ga{sub 0.94}Mn{sub 0.06}As{sub 1-y}P{sub y} layers grown by molecular beam epitaxy on GaAs substrates for y{<=}0.3. X-ray diffraction measurements reveal that the layers are under tensile strain, which gives rise to a magnetic easy axis perpendicular to the plane of the layers. The strength of the magnetic anisotropy and the coercive field increases as the phosphorous concentration is increased. The resistivity of all samples shows metallic behavior with the resistivity increasing as y increases. These materials will be useful for studies of micromagnetic phenomena requiring metallic ferromagnetic material with perpendicular magnetic anisotropy.

    In vivo biomedical research is pivotal to translate in vitro findings into clinical advances. Small academic institutions with limited resources find it virtually impossible to build and maintain typical rodent facilities for research. Zebrafish research has been demonstrated to be a valuable alternative for in vivo research in pharmacology, physiology, development and genetic studies. This article demonstrates that a functional zebrafish facility can be built in an easy and affordable manner. We demonstrate that such a facility could be built in about one working day with minimal tools and expertise. The cost of the 27 1.8 L fish tank zebrafish facility constructed in this study was approximately $1,500. We estimate that the maintenance of an initial working 150 fish colony for 3 months is $1,000. This project involved students, who were introduced to aquaculturing of zebrafish for research proposes.

    To develop an easy-energy-supply agent, medium-chain fatty acids (MCFAs) liposomes were prepared by thin-layer dispersion, freeze-thawing and dynamic high pressure microfluidization (DHPM)-freeze-thawing methods. Results showed that MCFAs nanoliposomes obtained by the novel method (DHPM-freeze-thawing) exhibited a smaller size (72.6 ± 4.9 nm), narrower size distribution (PDI = 0.175 ± 0.005), higher zeta potential (-41.27 ± 1.16 mV) and entrapment efficiency (45.9 ± 6.0%) compared to the other two methods. In the weight-loaded swimming test of the mice, the high-dose group of MCFAs nanoliposomes indicated a significantly longer swimming time (105 ± 31 min, p < 0.05), a lower serum urea nitrogen (839.5 ± 111.9 mg/L, p < 0.05) and blood lactic acid (5.7 ± 1.0 mmol/L, p ≤ 0.001), and a higher hepatic glycogen (15.0 ± 3.6 mg/g, p ≤ 0.001) than those of the control group (53 ± 13 min, 1153.6 ± 102.5 mg/L, 12.5 ± 1.9 mmol/L and 8.8 ± 3.3 mg/g, respectively). However, no significant difference was found between the high-dose group and MCFAs group. The results suggested that MCFAs nanoliposomes could be used as a potential easy-energy-supply agent.

    The European Activation SYstem has been re-engineered and re-written in modern programming languages so as to answer today's and tomorrow's needs in terms of activation, transmutation, depletion, decay and processing of radioactive materials. The new FISPACT-II inventory code development project has allowed us to embed many more features in terms of energy range: up to GeV; incident particles: alpha, gamma, proton, deuteron and neutron; and neutron physics: self-shielding effects, temperature dependence and covariance, so as to cover all anticipated application needs: nuclear fission and fusion, accelerator physics, isotope production, stockpile and fuel cycle stewardship, materials characterization and life, and storage cycle management. In parallel, the maturity of modern, truly general purpose libraries encompassing thousands of target isotopes such as TENDL-2012, the evolution of the ENDF-6 format and the capabilities of the latest generation of processing codes PREPRO, NJOY and CALENDF have allowed the activation code to be fed with more robust, complete and appropriate data: cross sections with covariance, probability tables in the resonance ranges, kerma, dpa, gas and radionuclide production and 24 decay types. All such data for the five most important incident particles (n, p, d, α, γ), are placed in evaluated data files up to an incident energy of 200 MeV. The resulting code system, EASY-II is designed as a functional replacement for the previous European Activation System, EASY-2010. It includes many new features and enhancements, but also benefits already from the feedback from extensive validation and verification activities performed with its predecessor.

  10. Temporal Learning and Rhythmic Responding: No Reduction in the Proportion Easy Effect with Variable Response-Stimulus Intervals

    PubMed Central

    Schmidt, James R.

    2016-01-01

    The present report further investigates the proportion easy effect, a conflict-free version of the proportion congruent effect. In the proportion easy paradigm, it is observed that the difference in performance between easy (high contrast) and hard (low contrast) items is smaller in a task with mostly hard items relative to a task with mostly easy items. This effect has been interpreted as evidence for temporal learning: participants learn a faster pace (i.e., rhythm of responding) in the mostly easy context, which boosts the contrast effect, and a slower pace in the mostly hard context. In the present experiment, intervals between trials were either fixed or randomly varied from trial to trial. Interestingly, the proportion easy effect was still present with variable intervals. These data suggest that participants do not learn the regularity in timing from one response to the next (which was highly inconsistent with variable intervals). As one alternative, participants might be learning the intervals between stimulus onset and responses, which were not manipulated. They could then use this learned timing information to prepare for responding at the anticipated time, resulting in rhythmic responding. The results further imply that variable response-stimulus intervals are insufficient for controlling for rhythmic biases. PMID:27199861

    By the time they reach age 18, American children will have seen 16,000 simulated murders and 200,000 acts of violence (American Psychiatric Association, 1998). Media violence can be hazardous to children's health, and studies point overwhelmingly to a causal connection between media violence and aggressive attitudes, values and behaviors in some children (Congressional Public Health Summit, 2000). Through education in clinics, schools, and primary care offices, pediatric nurses can minimize the impact of media violence. They can obtain comprehensive media histories on children and families. They can teach children and parents about the effects of media violence and advise them how to avoid exposure. Nurses can also encourage the entertainment industry to exercise more responsibility in the ways they entertain children. PMID:12593343

    2016-01-01

    The effects of concentrated fibroblast-conditioned media were tested to determine whether hepatocyte function can be maintained without direct contact between hepatocytes and fibroblasts. Primary rat hepatocytes cultured with a concentrated conditioned media of NIH-3T3 J2 cell line (final concentration of 55 mg/ml) showed significantly improved survival and functions (albumin and urea) compared to those of control groups. They also showed higher expression levels of mRNA, albumin and tyrosine aminotransferase compared to hepatocyte monoculture. The results suggest that culture with concentrated fibroblast-conditioned media could be an easy method for in vitro maintenance of primary hepatocytes. They also could be contribute to understand and analyze co-culture condition of hepatocyte with stroma cells. PMID:26863621

    NASA Astrophysics Data System (ADS)

    Pepona, Marianna; Favier, Julien

    2016-09-01

    In this work, we propose a numerical framework to simulate fluid flows in interaction with moving porous media of complex geometry. It is based on the Lattice Boltzmann method including porous effects via a Brinkman-Forchheimer-Darcy force model coupled to the Immersed Boundary method to handle complex geometries and moving structures. The coupling algorithm is described in detail and it is validated on well-established literature test cases for both stationary and moving porous configurations. The proposed method is easy to implement and efficient in terms of CPU cost and memory management compared to alternative methods which can be used to deal with moving immersed porous media, e.g. re-meshing at each time step or use of a moving/chimera mesh. An overall good agreement was obtained with reference results, opening the way to the numerical simulation of moving porous media for flow control applications.
