    Object-Oriented Technology (OOT), although not a new paradigm, has recently been prominently featured in the trade press and even general business publications. Indeed, the promises of object technology are alluring: the ability to handle complex design and engineering information through the full manufacturing production life cycle or to manipulate multimedia information, and the ability to improve programmer productivity in creating and maintaining high quality software. Groups at a number of the DOE facilities have been exploring the use of object technology for engineering, business, and other applications. In this white paper, the technology is explored thoroughly and compared with previous means of developing software and storing databases of information. Several specific projects within the DOE Complex are described, and the state of the commercial marketplace is indicated.

    2000-01-01

    Object oriented technologies are the corner stone of modern software development. A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

    The Stratospheric TeraHertz Observatory (STO) is a NASA funded, Long Duration Balloon experiment designed to address a key problem in modern astrophysics: understanding the Life Cycle of the Interstellar Medium. STO surveys a section of the Galactic plane in the dominant interstellar cooling line at 1.9 THz and the important star formation tracer at 1.46 THz, at ∼1 arc minute angular resolution, sufficient to spatially resolve atomic, ionic, and molecular clouds at 10 kpc. The STO instrument package uses a liquid helium cryostat to maintain the THz receiver at < 9 K and to cool the low noise amplifiers to < 20 K. The first STO mission (STO-1) flew in January of 2012 and the second mission (STO-2) is planned for December 2015. For the STO-2 flight a cryocooler will be added to extend the mission lifetime. This paper discusses the integration of the STO instrument into an existing cryostat and the cryogenic aspects of the launch and operation of the STO balloon mission in the challenging Antarctic environment.

  9. Reviews of computing technology: Object-oriented technology

    Energy Technology Data Exchange (ETDEWEB)

    Skeen, D.C.

    1993-03-01

    A useful metaphor in introducing object-oriented concepts is the idea of a computer hardware manufacturer assembling products from an existing stock of electronic parts. In this analogy, think of the parts as pieces of computer software and of the finished products as computer applications. Like its counterpart, the object is capable of performing its specific function in a wide variety of different applications. The advantages to assembling hardware using a set of prebuilt parts are obvious. The design process is greatly simplified in this scenario, since the designer needs only to carry the design down to the chip level, rather than to the transistor level. As a result, the designer is free to develop a more reliable and feature rich product. Also, since the component parts are reused in several different products, the parts can be made more robust and subjected to more rigorous testing than would be economically feasible for a part used in only one piece of equipment. Additionally, maintenance on the resulting systems is simplified because of the part-level consistency from one type of equipment to another. The remainder of this document introduces the techniques used to develop objects, the benefits of the technology, outstanding issues that remain with the technology, industry direction for the technology, and the impact that object-oriented technology is likely to have on the organization. While going through this material, the reader will find it useful to remember the parts analogy and to keep in mind that the overall purpose of object-oriented technology is to create software parts and to construct applications using those parts.

    Bernasconi, Pietro

    This is the Lead Proposal for the "Reflight of the Stratospheric TeraHertz Observatory: STO-2". STO-2 will address a key problem in modern astrophysics, understanding the Life Cycle of the Interstellar Medium (ISM). STO-2 will survey approximately 1/4 of the Southern Galactic plane in the dominant interstellar cooling line [CII] (158 μm) and the important star formation tracer [NII] (205 μm). With ~1 arcminute angular resolution, STO-2 will spatially resolve atomic, ionic and molecular clouds out to 10 kpc. Taking advantage of its enhanced, extended lifetime cryogenic receivers, the STO-2 survey will be conducted at unparalleled sensitivity levels. STO- 2 will uniquely probe the pivotal formative and disruptive stages in the life cycle of interstellar clouds and the relationship between global star formation rates and the properties of the ISM. Combined with previous HI and CO surveys, STO-2 will create 3-dimensional maps of the structure, dynamics, turbulence, energy balance, and pressure of the Milky Way's ISM, as well as the star formation rate. Once we gain an understanding of the relationship between ISM properties and star formation in the Milky Way, we can better interpret observations of nearby galaxies and the distant universe. The mission goals for these surveys are to: 1) Determine the life cycle of Galactic interstellar gas, 2) Study the creation and disruption of star-forming clouds in the Galaxy, 3) Determine the parameters that affect the star formation rate in the galaxy, and 4) Provide templates for star formation and stellar/interstellar feedback in other galaxies. STO-2 will re-use the 80cm telescope, gondola, and subsystems from STO-1. For the STO-2 flight, STO-1 s high spectral resolution (receiver system will be upgraded for extended cryogenic lifetime, enhanced sensitivity, and greater reliability. The flight receiver has eight, cryogenic HEB mixers; four optimized for the [CII] line and four for the [NII] line. STO-2 will also fly an

    Full Text Available Extrakorporal erzeugte Stoßwellen wurden erstmals 1980 zur Zertrümmerung von Nierensteinen eingesetzt und sind seitdem zur Methode der Wahl bei den meisten Steinen in Niere und Harntrakt geworden. Neben der Anwendung in der Lithotripsie werden Stoßwellen seit den 1990er Jahren zunehmend für eine Reihe von Indikationen im muskuloskelettalen Bereich mit Erfolg angewendet. Stoßwellen sind eine Form mechanischer Energie, die ohne Verletzung der Körperoberfläche durch die Haut in den Körper eingeleitet und in vorherbestimmten Tiefen zur Wirkung gebracht werden können. Erzeugt werden Stoßwellen in der Medizin durch elektrohydraulische, piezoelektrische oder elektromagnetische Verfahren. Je nach Anwendungsbereich wird die Energie mit Hilfe von akustischen Linsen oder Reflektoren fokussiert und mit Hilfe von bildgebenden Verfahren auf Zielgebiete im Körper gerichtet. Zur Charakterisierung der Stoßwellenfelder werden die Parameter Druck, Energie, Energieflußdichte und verschiedene Definitionen für die Fokus- und Behandlungszone verwendet. Neben der mechanischen Kraftentfaltung an akustischen Grenzflächen wird auch im Gewebe Kavitation erzeugt, die sekundär zu nadelstichartigen Belastungen von Grenzflächen führt. Auf Grund dieser Krafteinwirkungen sind einerseits Fragmentationseffekte an spröden Materialien (z. B. Nierensteine oder auch stimulierende Effekte wie Erzeugung von Aktionspotentialen an Nervenzellen und biologische Reaktionen durch Freisetzung verschiedener Stoffe zu verzeichnen. Obwohl speziell die biologischen Wirkungsmechanismen weitgehend unbekannt sind, wird die Stoßwellentherapie erfolgreich zur Steigerung der Blutversorgung und von Stoffwechselprozessen eingesetzt. Letztendlich werden darüber dauerhafte Heilungsprozesse angeregt.

    2015-03-01

    Full Text Available Authentication is an important requirement in various applications to restrict the non-legitimate access to certain resources. Radio Frequency Identification (RFID technology helps to perform the authentication task. The detection probability of an object during the authentication process can be increased using multiple number of RFID tags in the object. However, many security risks such as eavesdropping, location privacy etc. are involved in this technology. This paper proposes a secure and lightweight authentication scheme assuming the objects are attached with multiple number of RFID tags. Proper analysis has been carried out to evaluate the security of the proposed scheme, including comparison with a few existing schemes in terms of computation, communication and storage requirements.

    Data mining can effectively obtain the faint spatial object's patterns and characteristics, the universal relations and other implicated data characteristics, the key of which is classifier construction. Faint spatial object classifier construction with spatial data mining technology for faint spatial target detection is proposed based on theoretical analysis of design procedures and guidelines in detail. For the one-sidedness weakness during dealing with the fuzziness and randomness using this method, cloud modal classifier is proposed. Simulating analyzing results indicate that this method can realize classification quickly through feature combination and effectively resolve the one-sidedness weakness problem.

  4. Morphodynamic Modeling Using The SToRM Computational System

    Science.gov (United States)

    Simoes, F.

    2016-12-01

    The framework of the work presented here is the open source SToRM (System for Transport and River Modeling) eco-hydraulics modeling system, which is one of the models released with the iRIC hydraulic modeling graphical software package (http://i-ric.org/). SToRM has been applied to the simulation of various complex environmental problems, including natural waterways, steep channels with regime transition, and rapidly varying flood flows with wetting and drying fronts. In its previous version, however, channel bed was treated as static and the ability of simulating sediment transport rates or bed deformation was not included. The work presented here reports SToRM's newly developed extensions to expand the system's capability to calculate morphological changes in alluvial river systems. The sediment transport module of SToRM has been developed based on the general recognition that meaningful advances depend on physically solid formulations and robust and accurate numerical solution methods. The basic concepts of mass and momentum conservation are used, where the feedback mechanisms between the flow of water, the sediment in transport, and the bed changes are directly incorporated in the governing equations used in the mathematical model. This is accomplished via a non-capacity transport formulation based on the work of Cao et al. [Z. Cao et al., "Non-capacity or capacity model for fluvial sediment transport," Water Management, 165(WM4):193-211, 2012], where the governing equations are augmented with source/sink terms due to water-sediment interaction. The same unsteady, shock-capturing numerical schemes originally used in SToRM were adapted to the new physics, using a control volume formulation over unstructured computational grids. The presentation will include a brief overview of these methodologies, and the result of applications of the model to a number of relevant physical test cases with movable bed, where computational results are compared to experimental data.

    Many early web-based digital libraries (DLs) had implicit assumptions reflected in their architecture that the unit of focus in the DL (frequently "reports" or "e-prints") would only be manifested in a single, or at most a few, common file formats such as PDF or PostScript. DLs have now matured to the point where their contents are commonly no longer simple files. Complex objects in DLs have emerged from in response to various requirements, including: simple aggregation of formats and supporting files, bundling additional information to aid digital preservation, creating opaque digital objects for e-commerce applications, and the incorporation of dynamic services with the traditional data files. We examine a representative (but not necessarily exhaustive) number of current and recent historical web-based complex object technologies and projects that are applicable to DLs: Aurora, Buckets, ComMentor, Cryptolopes, Digibox, Document Management Alliance, FEDORA, Kahn-Wilensky Framework Digital Objects, Metadata Encoding & Transmission Standard, Multivalent Documents, Open eBooks, VERS Encapsulated Objects, and the Warwick Framework.

    The complex differential susceptibility a pure YBCO film and YBCO-STO-LCMO structures of different STO width (0; 2; 7 nm) is studied. It is shown, that a decrease of superconducting transition temperature T sub o nset and critical current density j sub c is observed, as expected for the structure YBCO-LCMO in comparison with the pure YBCO film. Conversely, the YBCO-STO-LCMO structures display an increase in T sub o nset; as for j sub c , it increases in the structure with 2 nm STO and decreases in that with 7 nm STO. It is suggested the pinning mechanism of vortices undergoes a change with decreasing temperature.

    Simões, Francisco J. M.

    2017-01-01

    A two-dimensional (depth-averaged) finite volume Godunov-type shallow water model developed for flow over complex topography is presented. The model, SToRM, is based on an unstructured cell-centered finite volume formulation and on nonlinear strong stability preserving Runge-Kutta time stepping schemes. The numerical discretization is founded on the classical and well established shallow water equations in hyperbolic conservative form, but the convective fluxes are calculated using auto-switching Riemann and diffusive numerical fluxes. Computational efficiency is achieved through a parallel implementation based on the OpenMP standard and the Fortran programming language. SToRM’s implementation within a graphical user interface is discussed. Field application of SToRM is illustrated by utilizing it to estimate peak flow discharges in a flooding event of the St. Vrain Creek in Colorado, U.S.A., in 2013, which reached 850 m3/s (~30,000 f3 /s) at the location of this study.

    The discovery of an electron gas at the interface between the two band insulators LaAlO{sub 3} (LAO) and SrTiO{sub 3} (STO) has initiated a huge effort to study this interface in detail. Later on other interesting properties such as induced ferromagnetism and superconductivity have been reported which make the LAO/STO interface a model system to study the fundamental physics of strongly correlated electronic system and also a candidate for future multifunctional oxide electronics. A reproducible nano-patterning technique is required to develop this unique interface into useful technologies. Here we present a reliable technique to physically pattern the quasi-two-dimensional electron gas (q2DEG) down to lateral dimensions as small as 100nm while maintaining its conducting properties. The fully industry compatible process uses electron beam lithography in combination with reactive ion etching. Temperature dependent transport properties of patterned Hall bars of various widths show a small size dependence of conductivity. The deviation can be explained by a narrow lateral depletion region.

    This document overviews an entirely new approach to determining the composition--the chemical-elemental, isotopic and molecular make-up--of complex, highly structured objects, moreover with microscopic spatial resolution in all 3 dimensions. The front cover depicts the new type of pulsed laser system at the heart of this novel technology under adjustment by Alexis Wynne, and schematically indicates two of its early uses: swiftly analyzing the 3-D composition governed structure of a transistor circuit with both optical and mass-spectrometric detectors, and of fossilized dinosaur and turtle bones high-speed probed by optical detection means. Studying the composition-cued 3-D micro-structures of advanced composite materials and the microscopic scale composition-texture of biological tissues are two near-term examples of the rich spectrum of novel applications enabled by this field-opening analytic tool-set.

    Objective structured clinical examinations (OSCEs) are multistationed clinical examinations that have been shown to be effective in testing students' ability to integrate the knowledge, skills, and attitudes acquired during their preclinical and clinical training and experiences. The original OSCE for the third-year Preventive Dentistry course at Baylor College of Dentistry was based on the traditional format consisting of four sections of twelve stations with a group of twelve students rotating through each of the sections simultaneously. This arrangement allowed for examination of one-half of the class. The other half of the class took the exam on an alternate date. To reduce the disruption caused by the students' moving from station to station and to allow for examination of the entire class in one setting, the traditional concept was modified using computer technology, and the twelve stations "moved" via a PowerPoint presentation while students remained stationary. Questions on both exams provided a means for testing data interpretation, diagnostic skills, and, to some extent, interpersonal skills. The overall atmosphere during the computer-based examination was less chaotic. Each student received identical instructions, explanations, and time allotments to respond to the information presented. The ratio of faculty to students required to monitor the exam was less than required for the traditional format. Additionally, since there was no need to allow time for student transition, the total time required to administer the exam was reduced. Thus, objective assessment of the entire class was accomplished using fewer faculty members and less class time and with less disruption for the students.

    2015-03-01

    La0.7Sr0.3MnO3 (LSMO) is a very attractive material for spintronics due to its half-metallic ferromagnetic properties. The LSMO films are epitaxially grown on STO (100) substrates using pulsed laser deposition. The effects of substrate temperature, laser power, oxygen pressure, and annealing on the LSMO growth are systematically investigated by the reflection high energy electron diffraction and atomic force microscopy. Under the optimized growth condition, we have achieved atomically flat LSMO thin films with a wide terrace width of more than 5 micro-meters. The electrical transport properties of LSMO thin films of various thicknesses ranging from 8 to 20 monolayers are studied by measuring the resistivity as a function of temperature. We find that the growth condition plays an important role in the critical film thickness for the metal-insulator transition and the Curie temperature.

  18. Salt tolerance (STO), a stress-related protein, has a major role in light signalling.

    Science.gov (United States)

    Indorf, Martin; Cordero, Julio; Neuhaus, Gunther; Rodríguez-Franco, Marta

    2007-08-01

    The salt tolerance protein (STO) of Arabidopsis was identified as a protein conferring salt tolerance to yeast cells. In order to uncover its function, we isolated an STO T-DNA insertion line and generated RNAi and overexpressor Arabidopsis plants. Here we present data on the hypocotyl growth of these lines indicating that STO acts as a negative regulator in phytochrome and blue-light signalling. Transcription analysis of STO uncovered a light and circadian dependent regulation of gene expression, and analysis of light-regulated genes revealed that STO is involved in the regulation of CHS expression during de-etiolation. In addition, we could show that CONSTITUTIVE PHOTOMORPHOGENESIS 1 (COP1) represses the transcription of STO and contributes to the destabilization of the protein in etiolated seedlings. Microscopic analysis revealed that the STO:eGFP fusion protein is located in the nucleus, accumulates in a light-dependent manner, and, in transient transformation assays in onion epidermal cells, co-localizes with COP1 in nuclear and cytoplasmic aggregations. However, the analysis of gain- and loss-of-function STO mutants in the cop1-4 background points towards a COP1-independent role during photomorphogenesis.

    Science.gov (United States)

    Simoes, Francisco J.

    2009-01-01

    SToRM (System for Transport and River Modeling) is a numerical model developed to simulate free surface flows in complex environmental domains. It is based on the depth-averaged St. Venant equations, which are discretized using unstructured upwind finite volume methods, and contains both steady and unsteady solution techniques. This article provides a brief description of the numerical approach selected to discretize the governing equations in space and time, including important aspects of solving natural environmental flows, such as the wetting and drying algorithm. The presentation is illustrated with several application examples, covering both laboratory and natural river flow cases, which show the model’s ability to solve complex flow phenomena.

  1. Optical technologies for the observation of low Earth orbit objects

    CERN Document Server

    Hampf, Daniel; Riede, Wolfgang

    2015-01-01

    In order to avoid collisions with space debris, the near Earth orbit must be continuously scanned by either ground- or spaced-based facilities. For the low Earth orbit, radar telescopes are the workhorse for this task, especially due to their continuous availability. However, optical observation methods can deliver complementary information, especially towards high accuracy measurements. Passive-optical observations are inexpensive and can yield very precise information about the apparent position of the object in the sky via comparison with background stars. However, the object's distance from the observer is not readily accessible, which constitutes a major drawback of this approach for the precise calculation of the orbital elements. Two experimental methods have been devised to overcome this problem: Using two observatories a few kilometres apart, strictly simultaneous observations of the same object yield an accurate, instantaneous 3D position determination through measurement of the parallax. If only on...

    Kawamura, Jonathan

    Here we propose "STO-2: Support for 4th Year Operations, Recovery, and Science," a project being led by Dr. Christopher Walker of the University of Arizona. The Stratospheric TeraHertz Observatory was ready for its second Antarctic flight (STO-2) in the 2015-2016 austral summer. However, due to the late establishment of the stratospheric anti-cyclone and poor surface conditions, STO-2 was unable to launch. The decision was made to winter-over the STO-2 payload in its hangar for launch during the 2016-2017 Antarctic campaign. Funds to cover preparations and deployment of key members of the instrument team in support of the campaign are being provided by NASA under the existing grant. However, these funds are only sufficient to cover expenses up to December 31st, 2016. Here, we request resources for calendar year 2017 to support mission operations, payload recovery, and science operations. These elements will enable the team to deliver fully on STO-2's science mission, and maximize NASA's demonstrated investment in STO-2's success. STO-2 addresses a key problem in modern astrophysics: understanding the Life Cycle of the Interstellar Medium (ISM). STO-2 will survey approximately ˜ of the Southern Galactic Plane in the dominant interstellar cooling line [CII] (158 μm) and the important star formation tracer [NII] (205 μm). In addition, STO-2 will perform path finding observations of the 63 μm [OI] line toward selected regions. With 1 arcminute angular resolution, STO-2 will spatially resolve atomic, ionic and molecular clouds out to 10 kpc. The STO-2 survey will be conducted at unparalleled sensitivity levels. STO-2 will uniquely probe the pivotal formative and disruptive stages in the life cycle of interstellar clouds and the relationship between global star formation rates and the properties of the ISM. Combined with previous HI and CO surveys, STO-2 will create 3- dimensional maps of the structure, dynamics, turbulence, energy balance, and pressure of the Milky

  6. The use of software agents and distributed objects to integrate enterprises: Compatible or competing technologies?

    Energy Technology Data Exchange (ETDEWEB)

    Pancerella, C.M.

    1998-04-01

    Distributed object and software agent technologies are two integration methods for connecting enterprises. The two technologies have overlapping goals--interoperability and architectural support for integrating software components--though to date little or no integration of the two technologies has been made at the enterprise level. The primary difference between these two technologies is that distributed object technologies focus on the problems inherent in connecting distributed heterogeneous systems whereas software agent technologies focus on the problems involved with coordination and knowledge exchange across domain boundaries. This paper addresses the integration of these technologies in support of enterprise integration across organizational and geographic boundaries. The authors discuss enterprise integration issues, review their experiences with both technologies, and make recommendations for future work. Neither technology is a panacea. Good software engineering techniques must be applied to integrate an enterprise because scalability and a distributed software development team are realities.

    Electron gas arizen at the insulating oxide interfaces exhibits high electron mobility, tunable carrier densities and related unique behaviors such as coexistence of superconductivity and ferromagnetism, Kondo resistance, etc. Itinerant electrons at the oxide hetero-interface are predicted to have long spin diffusion length, while they are under the relatively strong Rashba-type spin orbit coupling due to inversion symmetry breaking. We studied non-local spin signal induced by spin orbit coupling with additional gate-controlled Rashba field in quasi-2DEG of LaAlO3/SrTiO (LAO/STO) interface. We fabricated simple hall-bar like geometry to measure non-local signal with the variation of channel length (2 ~ 10 μm). Cleaned sample was patterned using e-beam lithography and reactive ion etching followed by oxygen treatment to anneal out oxygen vacancies. When an electric current flows one line of the hall bar structure, spin orbit coupling will induce the current flow away from the source current channel via spin hall and inverse spin hall effects. The non-local signals were studied under different angles of magnetic field and the variation of applied gate voltage. This work was supported by a grant from (No. 1.140092.01) funded by the Ulsan National Institute of Science and Technology.

    Deducting the future switching of the road transport energy technology is one of the key preconditions for relative technology development planning. However,one of the difficulties is to address the issue of multi-objective and conflicting constrains, e.g., minimizing the climate mitigation or minimizing economic cost. In this paper, a dynamic optimization model was established, which can be used to analyze the road transport energy technology switching under multi-objective constrains.Through one case study, a series of solutions could be derived to provide decision-makers with the flexibility to choose the appropriate solution with respect to the given situation.

    Microstructure of Yittria Stabilized Zirconia (YSZ) and Strontium Titanate (STO) of radio frequency magnetron sputtered buffer layers was studied at various sputtering conditions on Si (100), Sapphire and LaAlO3 (100) substrates. The effect of substrate temperatures up to 800 C and sputtering gas pressures in the range of 50 mTorr. of growth conditions was studied. The buffer layers of YSZ and STO showed a strong tendency for columnar growth was observed above 15 mTorr sputtering gas pressure and at high substrate temperatures. Post annealing of these films in oxygen atmosphere reduced the oxygen deficiency and strain generated during growth of the films. Strong c-axis oriented superconducting YBa2Cu3O7-x (YBCO) thin films were obtained on these buffer layers using pulsed laser ablation technique. YBCO films deposited on multilayers of YSZ and STO were shown to have better superconducting properties.

    2002-05-03

    STO-609, a selective inhibitor of Ca(2+)/calmodulin-dependent protein kinase kinase (CaM-KK) was synthesized, and its inhibitory properties were investigated both in vitro and in vivo. STO-609 inhibits the activities of recombinant CaM-KK alpha and CaM-KK beta isoforms, with K(i) values of 80 and 15 ng/ml, respectively, and also inhibits their autophosphorylation activities. Comparison of the inhibitory potency of the compound against various protein kinases revealed that STO-609 is highly selective for CaM-KK without any significant effect on the downstream CaM kinases (CaM-KI and -IV), and the IC(50) value of the compound against CaM-KII is approximately 10 microg/ml. STO-609 inhibits constitutively active CaM-KK alpha (glutathione S-transferase (GST)-CaM-KK-(84-434)) as well as the wild-type enzyme. Kinetic analysis indicates that the compound is a competitive inhibitor of ATP. In transfected HeLa cells, STO-609 suppresses the Ca(2+)-induced activation of CaM-KIV in a dose-dependent manner. In agreement with this observation, the inhibitor significantly reduces the endogenous activity of CaM-KK in SH-SY5Y neuroblastoma cells at a concentration of 1 microg/ml (approximately 80% inhibitory rate). Taken together, these results indicate that STO-609 is a selective and cell-permeable inhibitor of CaM-KK and that it may be a useful tool for evaluating the physiological significance of the CaM-KK-mediated pathway in vivo as well as in vitro.

    2010-01-01

    Researches on Augmented Reality (AR) have recently received attention. With these, the Machine-to-Machine (M2M) market has started to be active and there are numerous efforts to apply this to real life in all sectors of society. To date, the M2M market has applied the existing marker-based AR technology in entertainment, business and other industries. With the existing marker-based AR technology, a designated object can only be loaded on the screen from one marker and a marker has to be added to load on the screen the same object again. This situation creates a problem where the relevant marker'should be extracted and printed in screen so that loading of the multiple objects is enabled. However, since the distance between markers will not be measured in the process of detecting and copying markers, the markers can be overlapped and thus the objects would not be augmented. To solve this problem, a circle having the longest radius needs to be created from a focal point of a marker to be copied, so that no object is copied within the confines of the circle. In this paper, software-based sensing technology for multiple object detection and loading using PPHT has been developed and overlapping marker control according to multiple object control has been studied using the Bresenham and Mean Shift algorithms.

    2017-07-01

    The present study aimed to develop the theoretical construct and examine the psychometric properties of a new scale for measuring subjective traumatic outlook (STO) among individuals exposed to traumatic events. The main idea behind this construct is to assess individual differences in the way people exposed to traumatic experiences subjectively perceive their trauma. Using four samples, we conducted five studies that examine the new questionnaire's exploratory/confirmatory factor analysis (EFA/CFA), test-retest reliability, and construct validity. The STO was best captured by a five-item factor construct. This construct was found to have good convergent validity with similar, related subjective evaluations of PTSD and PTSD-related constructs. Yet, the STO also has unique and divergent properties compared to other questionnaires. The STO is a new, short questionnaire with excellent psychometric properties. It may provide practitioners with a good screening tool for attaining first impression about one's inner traumatic world, and predicting future risk for developing PTSD. Copyright © 2017.

    Microstructure of Yittria Stabilized Zirconia (YSZ) and Strontium Titanate (STO) of radio frequency magnetron sputtered buffer layers was studied at various sputtering conditions on Si<100>, Sapphire and LaAlO{sub 3} <100> substrates. The effect of substrate temperatures upto 800 C and sputtering gas pressures in the range of 50 mTorr. of growth conditions was studied. The buffer layers of YSZ and STO showed a strong tendency for columnar structure with variation growth conditions. The buffer layers of YSZ and STO showed orientation. The tendency for columnar growth was observed above 15 mTorr sputtering gas pressure and at high substrate temperatures. Post annealing of these films in oxygen atmosphere reduced the oxygen deficiency and strain generated during growth of the films. Strong c-axis oriented superconducting YBa{sub 2}Cu{sub 9}O{sub 7-x} (YBCO) thin films were obtained on these buffer layers using pulsed laser ablation technique. YBCO films deposited on multilayers of YSZ and STO were shown to have better superconducting properties.

    We perform first-principle calculations of the FeSe monolayer on STO with the focus on three central aspects. First, compared to experiment, the bulk lattice constant of FeSe is too small in LDA, PBEsol and Perdew-Burgke-Ernzerhof (PBE) type exchange-correlation (xc) functionals while in bulk SrTiO3 (STO) LDA over-binds, PBE under-binds and PBEsol agrees best with experiment. Thus, the strain in the FeSe monolayer on STO depends on the xc functional and, especially in the non-magnetic state, is strongly overestimated and best described in PBEsol. In agreement with earlier work, we find that the band structure of the checkerboard antiferromagnetic configuration agrees best with experiment where, in addition, the relative strain on FeSe is best described. Second, our focus is on the crystal structure of the interface itself. The FeSe/STO distance depends weakly on the presence of magnetism and PBE results agree best with recent experimental data. We find that a double {{TiO}}2-layer below the FeSe relaxes to a structure in disagreement with experimental data. On the other hand, considering the effect of oxygen-vacancies in the single {{TiO}}2 terminated slab within the virtual crystal approximation, in agreement with recent experiment, the FeSe monolayer Ti layer distance increases for a small vacancy concentration (<20%). Third, we investigate the charge-transfer to FeSe due to oxygen-vacancies in STO. Interestingly, we find negligible charge transfer for small concentrations—only above 20% a significant charge transfer is observed.

    Full Text Available A fast version of correlation algorithm to track objects on video-sequences made by a nonstabilized camcorder is presented. The algorithm is based on comparison of local correlations of the object image and regions of video-frames. The algorithm is implemented in programming technology CUDA. Application of CUDA allowed to attain real time execution of the algorithm. To improve its precision and stability, a robust version of the Kalman filter has been incorporated into the flowchart. Tests showed applicability of the algorithm to practical object tracking.

  8. A multi-objective stochastic approach to combinatorial technology space exploration

    Science.gov (United States)

    Patel, Chirag B.

    Historically, aerospace development programs have frequently been marked by performance shortfalls, cost growth, and schedule slippage. New technologies included in systems are considered to be one of the major sources of this programmatic risk. Decisions regarding the choice of technologies to include in a design are therefore crucial for a successful development program. This problem of technology selection is a challenging exercise in multi-objective decision making. The complexity of this selection problem is compounded by the geometric growth of the combinatorial space with the number of technologies being considered and the uncertainties inherent in the knowledge of the technological attributes. These problems are not typically addressed in the selection methods employed in common practice. Consequently, a method is desired to aid the selection of technologies for complex systems design with consideration of the combinatorial complexity, multi-dimensionality, and the presence of uncertainties. Several categories of techniques are explored to address the shortcomings of current approaches and to realize the goal of an efficient and effective combinatorial technology space exploration method. For the multi-objective decision making, a posteriori preference articulation is implemented. To realize this, a stochastic algorithm for Pareto optimization is formulated based on the concepts of SPEA2. Techniques to address the uncertain nature of technology impact on the system are also examined. Monte Carlo simulations using the surrogate models are used for uncertainty quantification. The concepts of graph theory are used for modeling and analyzing compatibility constraints among technologies and assessing their impact on the technology combinatorial space. The overall decision making approach is enabled by the application of an uncertainty quantification technique under the framework of an efficient probabilistic Pareto optimization algorithm. As a result, multiple

    To assess the isoform specificity of the Ca(2+)/calmodulin-dependent protein kinase kinase (CaMKK)-mediated signaling pathway using a CaMKK inhibitor (STO-609) in living cells, we have established A549 cell lines expressing STO-609-resistant mutants of CaMKK isoforms. Following serial mutagenesis studies, we have succeeded in obtaining an STO-609-resistant CaMKKα mutant (Ala292Thr/Leu233Phe) and a CaMKKβ mutant (Ala328Thr/Val269Phe), which showed sensitivity to STO-609 that was 2-3 orders of magnitude lower without an appreciable effect on kinase activity or CaM requirement. These results are consistent with the results obtained for CaMKK activities in the extracts of A549 cells stably expressing the mutants of CaMKK isoforms. Ionomycin-induced 5'-AMP-activated protein kinase (AMPK) phosphorylation at Thr172 in A549 cells expressing either the wild-type or the STO-609-resistant mutant of CaMKKα was completely suppressed by STO-609 treatment but resistant to the inhibitor in the presence of the CaMKKβ mutant (Ala328Thr/Val269Phe). This result strongly suggested that CaMKKβ is responsible for ionomycin-induced AMPK activation, which supported previous reports. In contrast, ionomycin-induced CaMKIV phosphorylation at Thr196 was resistant to STO-609 treatment in A549 cells expressing STO-609-resistant mutants of both CaMKK isoforms, indicating that both CaMKK isoforms are capable of phosphorylating and activating CaMKIV in living cells. Considering these results together, STO-609-resistant CaMKK mutants developed in this study may be useful for distinguishing CaMKK isoform-mediated signaling pathways in combination with the use of an inhibitor compound.

    The oil and gas pipeline industry relies on the use of carbon and low-alloy steels. As such, there is a need to predict the corrosivity of brines containing carbon dioxide (CO{sub 2}) when designing production equipment and transportation facilities. A true industry-standard approach to predicting CO{sub 2} and hydrogen sulphide (H{sub 2}S) corrosion does not exist, but there are similarities in existing approaches and models. This paper reviewed the Systematic Treatment of Pitting Sequence (SToPS) software program developed by the materials assessment team at Natural Resources Canada to predict the internal pitting corrosion rate of multiphase, oil producing, gas producing, oil transmission, and gas transmission pipelines. The main output of SToPS is the prediction of how long the pipe is safe. SToPS considers the pipeline to be safe until the depth of the deepest pit is 50 percent of the pipe wall thickness. In addition, SToPS predicts pH, wall shear stress, flow regime, as well as the probability of pitting corrosion. SToPS requires details about pipeline properties, production conditions of the pipeline and gas composition in order to accurately predict the pitting corrosion. SToPS calculates the pitting corrosion rate by combining the effect of 11 different operational parameters. This paper explained how each of these components affects the pitting corrosion rate and how to calculate their individual corrosion rates. The paper showed that each operational parameter can alter the pitting corrosion rate. There are currently 2 versions of SToPS, notably SToPS v1.1, and SToPS v2.0 which produces 7 different graphs to help the user understand the corrosion occurring in their pipeline over the production periods. 16 refs., 1 tab., 6 figs.

    Full Text Available BiFeO3 thin films with a mixture of tunable R-like and c axis elongated low symmetry phase (T-like phase are fabricated on STO (001 substrate through controlling of the substrate temperature. Almost pure T-like phase can be grown on STO substrate at 600°C. Comparing with the situations on LAO (001, it is found that, strains from the LAO substrate may be the only reason that induces the T-like phase at higher temperatures. At lower temperatures, the island growth induced strains alone can also generate T-like phase on STO substrate.

    Bernasconi, Pietro

    This is a collaboration Co-I Institution proposal for the proposal "STO-2: Support for 4th Year Operations, Recovery, and Science" whose lead proposal is submitted by the University of Arizona with Dr. Christofer Walker as PI. STO-2 was flight-ready in the 2015-2016 austral summer. However, due to the late establishment of the stratospheric anti-cyclone and poor surface conditions, STO-2 was unable to launch. The decision was made to winter-over the STO-2 payload in its hangar for launch during the 2016-2017 Antarctic campaign. Funds to cover preparations and deployment of key members of the instrument team in support of the campaign are being provided by NASA under the existing grant. However, these funds are only sufficient to cover expenses up to approximately December 31st. Here we request supplemental funds to cover costs associated with STO-2 operations and recovery beyond this date. STO-2 will address a key problem in modern astrophysics, understanding the Life Cycle of the Interstellar Medium (ISM). STO-2 will survey approximately 1/4 of the Southern Galactic Plane in the dominant interstellar cooling line [CII] (158 μm) and the important star formation tracer [NII] (205 μm). In addition, STO-2 will perform path finding observations of the 63 μm [OI] line toward selected regions. With 1 arcminute angular resolution, STO-2 will spatially resolve atomic, ionic and molecular clouds out to 10 kpc. The STO-2 survey will be conducted at unparalleled sensitivity levels. STO-2 will uniquely probe the pivotal formative and disruptive stages in the life cycle of interstellar clouds and the relationship between global star formation rates and the properties of the ISM. Combined with previous HI and CO surveys, STO-2 will create 3-dimensional maps of the structure, dynamics, turbulence, energy balance, and pressure of the Milky Way's ISM, as well as the star formation rate. Once we gain an understanding of the relationship between ISM properties and star formation

    The tracking technology of the moving object has been an active topic of the visual tracking system. In this paper, the tracking algorithms are classified into four classes: correlation-based methods, boundary-based methods, model-based methods and multifunctional methods. Based on the analysis of the advantages and disadvantages of all these algorithms, a new tracking algorithm, integrating SSDA and advanced Camshift algorithm, is put forward here.

    Mouse embryonic stem (ES) cell lines, which were established by culturing on feeder cells, have usually been cultured without feeder cells in the presence of leukemia inhibitory factor. However, proliferating rate of ES cells in the condition is often lower than that with feeder cells. Here, we found that conditioned medium (CM) from feeder cells (STO cells) increased the number of undifferentiated cells in a culture dish by promoting attachment of ES cells. The attached cells were increased in 4 h after replating ES cells in the presence of CM from STO cells, and they formed flat colonies composed of undifferentiated cells. This culture system with CM from feeder cells is useful in preparing a large number of well-defined ES cells. In addition, from present experiments we found that the dish double-coated with gelatin and CM was extremely useful for culturing ES cells.

    Embryoid bodies, which are similar to post-implantation egg-cylinder stage embryos, provide a model for the study of embryo development and stem cell differentiation. We describe here a novel method for generating embryoid bodies from murine embryonic stem (ES) cells cultured on the STO feeder layer. The ES cells grew into compact aggregates in the first 3 days of coculture, then became simple embryoid bodies (EBs) possessing primitive endoderm on the outer layer. They finally turned into cystic embryoid bodies after being transferred to Petri dishes for 1-3 days. Evaluation of the EBs in terms of morphology and differentiating potential indicates that they were typical in structure and could generate cells derived from the three germ layers. The results show that embryoid bodies can form not only in suspension culture but also directly from ES cells cultured on the STO feeder layer.

    Full Text Available Catalysis is an important area of chemistry, with an extensive amount of work going on in this area of sciences, toward synthesis and evaluation of newer catalysts. There are many reports for different conversion reactions such as oxidation, reduction, coupling, alkylation, and acylation for which various catalysts have been used such as mixed metal oxides, metal nanoparticles, metal organic complexes and many others. Among the many catalysts reported, the one catalyst that caught our attention due to its exploitation for a plethora of organic conversions is the sulfated tin oxide (STO, which is due to the low cost, greater stability and high efficiency of the catalyst. In this review, we have attempted to compile data about the structural properties of STO, and its applications as catalysts in various organic synthesis are presented. The literature data up to 2014 were collected and considered for the review.

    A coculture system for in vitro proliferation of rat primary hepatocytes with feeder cells was investigated with the view of constructing a hybrid artificial liver module using human hepatocytes. A mouse cell line, STO, was apparently effective compared with other kinds of feeder cells such as FLS5 and MRC5 in increasing the total cell number in the coculture of rat primary hepatocytes. The parenchymal hepatocyte, which are polygonal cells, spread well as the cultivation progressed. Monitoring of parenchymal hepatocyte colonies under a microscope showed that the area of each colony increased as the single culture and cocultures progressed. The adhesion area per hepatocyte increased little during the coculture with STO cells, while the adhesion area increased markedly in the single culture of hepatocytes. The density of hepatocytes increased more than two times during the coculture for 5 d, while it decreased during the single culture. The production rate of urea by hepatocytes markedly increased during the coculture, while the rate in the single culture was lower than the coculture and increased only slightly. The specific rate of urea production by hepatocytes in the coculture did not decrease even as the hepatocytes grew. Consequently, rat primary hepatocytes could proliferate in vitro by coculture with STO cells without a decrease in urea production activity.

    This study followed the teaching-learning process about the nursing consultation, based on digital learning objects developed through the active Problem Based Learning method. The goals were to evaluate the digital learning objects about nursing consultation, develop cognitive skills on the subject using problem based learning and identify the students' opinions on the use of technology. This is an exploratory and descriptive study with a quantitative approach. The sample consisted of 71 students in the sixth period of the nursing program at the Federal University of Rio Grande do Sul. The data was collected through a questionnaire to evaluate the learning objects. The results showed positive agreement (58%) on the content, usability and didactics of the proposed computer-mediated activity regarding the nursing consultation. The application of materials to the students is considered positive.

    Flowering at the appropriate time is crucial for reproductive success and is strongly influenced by various pathways such as photoperiod, circadian clock, FRIGIDA and vernalization. Although each separate pathway has been extensively studied, much less is known about the interactions between them. In this study we have investigated the relationship between the photoperiod/circadian clock gene and FRIGIDA/FLC by characterizing the function of the B-box STO gene family. STO has two B-box Zn-finger domains but lacks the CCT domain. Its expression is controlled by circadian rhythm and is affected by environmental factors and phytohormones. Loss and gain of function mutants show diversiform phenotypes from seed germination to flowering. The sto-1 mutant flowers later than the wild type (WT) under short day growth conditions, while over-expression of STO causes early flowering both in long and short days. STO over-expression not only reduces FLC expression level but it also activates FT and SOC1 expression. It also does not rely on the other B-box gene CO or change the circadian clock system to activate FT and SOC1. Furthermore, the STO activation of FT and SOC1 expression is independent of the repression of FLC; rather STO and FLC compete with each other to regulate downstream genes. Our results indicate that photoperiod and the circadian clock pathway gene STO can affect the key flowering time genes FLC and FT/SOC1 separately, and reveals a novel perspective to the mechanism of flowering regulation.

    Regulating the intracellular Na+/K+ ratio is an essential process for salinity tolerance. The yeast mutant, can, which is deficient in calcineurin, can not grow on medium containing Na+ because it is unable to regulate the intracellular Na+/K+ ratio. Expression of the STO gene of Arabidopsis thaliana in the can mutant complements the salt-sensitive phenotype. A protein of Arabidopsis, an H-protein promoter binding factor (HPPBF-1), that binds to STO protein was isolated. HPPBF-1 cDNA has a sequence encoding a Myb DNA binding-motif and its gene expression is induced by salt stress. Furthermore, HPPBF-1 protein is localized in the nucleus. Although, the expression level of STO is not induced under salt-stress conditions, overexpression of STO in a transgenic Arabidopsis plant gave it a higher salt tolerance than was observed in the wild type. When STO transgenic plants and wild-type plants were subjected to salt stress, root growth was increased by 33-70% in the transgenic plants under salt stress. These results suggest that STO is involved in salt-stress responses in Arabidopsis.

    2016-01-01

    Full Text Available Innovation activities, as well as innovations, are closely related meanings, and like many others economical definitions, have a broad range of meanings. Main characteristics and attributes of innovation involves new or significantly improved product, that’s being used, or in other words, found its application, and innovative activities – activities focused on realization of innovations. In this article, innovations are mainly considered in terms of high-technology production, evidence from Russian space industry. There are 5 basic stages of lifecycle of innovative project in considered industry: initiation, development, realization, expansion, consumption. Practically, third or fourth, or even both of these stages, often missing because there is no need of them. R&D activities, or even further serial production, based on previous developments, is an innovation activity, because these activities are stages of innovative projects lifecycle itself. Then it seems legit, to draw a conclusion, that in terms of high-technology production, company’s primary activity equals innovative activity. Basic characteristics of innovative activity of high-technology companies as assessment and forecasting object involves high level of uncertainty at every stage of projects lifecycle, high dependency on funding level of this activity, and high level and erratic structure of risk. All the above mentioned, means that assessment and forecasting of innovative activity of high-technology companies, needs development of its own methodological tools for each industry.

    2012-01-01

    The concern for reducing aviation safety risk is rising as the National Airspace System in the United States transforms to the Next Generation Air Transportation System (NextGen). The NASA Aviation Safety Program is committed to developing an effective aviation safety technology portfolio to meet the challenges of this transformation and to mitigate relevant safety risks. The paper focuses on the reasoning of selecting Object-Oriented Bayesian Networks (OOBN) as the technique and commercial software for the accident modeling and portfolio assessment. To illustrate the benefits of OOBN in a large and complex aviation accident model, the in-flight Loss-of-Control Accident Framework (LOCAF) constructed as an influence diagram is presented. An OOBN approach not only simplifies construction and maintenance of complex causal networks for the modelers, but also offers a well-organized hierarchical network that is easier for decision makers to exploit the model examining the effectiveness of risk mitigation strategies through technology insertions.

    The conformations of 3-(substituted furan-2-yl) and 3-(substituted thien-2-yl)-γ-aminobutyric acid 1-9 in solution (D 2O) are estimated from high-resolution (300 MHz) 1H NMR coupling data. Conformations and populations of conformers are calculated by means of a modified Karplus-like relationship for the vicinal coupling constants. The results are compared with X-ray crystallographic investigations (torsion angles) and ab initio HF MO ST-3G or STO-3G* calculations. 1H NMR spectral analysis shows how 1-9 in solution retain the preferred g- conformation around the C3C4 bond, as found in the solid state, while a partial rotation is set up around the C2C3 bond: the conformations about C2C3 are all highly populated in solution. The 13C spin-lattice relaxation times are also discussed.

    2016-05-01

    We present a 220 GHz 3D imaging `Pathfinder' radar developed within the EU FP7 project CONSORTIS (Concealed Object Stand-Off Real-Time Imaging for Security) which has been built to address two objectives: (i) to de-risk the radar hardware development and (ii) to enable the collection of phenomenology data with ~1 cm3 volumetric resolution. The radar combines a DDS-based chirp generator and self-mixing multiplier technology to achieve a 30 GHz bandwidth chirp with such high linearity that the raw point response is close to ideal and only requires minor nonlinearity compensation. The single transceiver is focused with a 30 cm lens mounted on a gimbal to acquire 3D volumetric images of static test targets and materials.

  10. Fetal subjects and maternal objects: reproductive technology and the new fetal/maternal relation.

    Science.gov (United States)

    Squier, S

    1996-10-01

    This essay examines three tendencies nurtured in the practices of reproductive technology - tendencies with profoundly disturbing implications for us as individuals and as social beings. They are: 1) the increasing subjectification of the fetus (that is, the increasing tendency to posit a fetal subject), 2) the increasing objectification of the gestating woman, leading to her representation as interchangeable object rather than unique subject, and 3) the increasing tendency to conceive of the fetus and the mother as social, medical, and legal antagonists. Considering the construction of fetus, mother, and the fetal/maternal relation in earlier (Western) historical periods, a contemporary work of literature, a government report, and the popular press, I argue that as the fetus is increasingly being understood as a subject, the mother is increasingly being reduced to an antagonist, an obstacle to fetal health, and an object. The essay concludes by offering some tentative conclusions about the general process of fetal subjectification in the United States and Europe.

    Desert "RATS" (Research and Technology Studies) is a combined, multi-discipline group of inter-NASA center scientists and engineers, net-working and collaborating with representatives of industry and academia, for the purpose of conducting planetary surface exploration-focused remote field exercises. These integrated testing exercises conducted under representative analog Lunar and Mars surface terrain conditions, provide NASA the capability to validate experimental prototype hardware and software systems as well as to evaluate and develop mission operational techniques in order to identify and establish technical requirements and identify potential technology "gaps" applicable for future planetary human exploration. The 2007 D-RATS field campaign test activities were initiated based on the major themes and objectives of a notional 5-year plan developed for conducting relative analog test activities in support of the engineering evaluation and assessment of various system architectural requirements, conceptual prototype support equipment and selected technologies necessary for the establishment of a lunar outpost. Specifically, the major objectives included measuring task efficiency during robot, human, and human-robot interactive tasks associated with lunar outpost site surveying and reconnaissance activities and deployment of a representative solar panel power and distribution system. In addition, technology demonstrations were conducted with a new Lithium-ion battery and autonomous software to coordinate multiple robot activities. Secondary objectives were evaluating airlock concept mockups and prototype removable space suit over-garment elements for dust mitigation, and upgrades to the prototype extravehicular activities (EVA) communication and information system. Dry run test activities, prior to testing at a designated remote field site location, were initially conducted at the Johnson Space Center (JSC) Remote Field Demonstration Test Site. This is a multi

    Full Text Available We consider combined control in automatic control systems for technological objects trajectory movements. We present research results of the system disturbance invariance ensuring on the example of the technological manipulator that implements hydrocutting of the oil pipelines. Control is based on the propositions of the fourth modified invariance form with the use of bootstrapping methods. The paper presents analysis of results obtained by two different correction methods. The essence of the first method lies in injection of additional component into the already established control signal and formation of the channel for that component. Control signal correction during the signal synthesis stage in the control device constitutes the basis for the second method. Research results have shown high efficiency of application for both correction methods. Both methods have roughly the same precision. We have shown that the correction in the control device is preferable because it has no influence on the inner contour of the system. We have shown the necessity of the block usage with the variable transmission coefficient, which value is determined by technological trajectory parameters. Research results can be applied in practice for improvement of the precision specifications of automatic control systems for trajectorial manipulators.

    Feeder cells are generally required for establishment and maintenance of embryonic stem (ES)/induced pluripotent stem (iPS) cells. Increased demands for generation of those cells carrying various types of vectors (i.e., KO vectors and transgenes) also require feeder cells that confer resistance to any types of preexisting selective drugs. Unfortunately, the use of the feeders that are resistant to various drugs appears to be limited to a few laboratories. Here we generated a set of gene-engineered STO feeder cells that confer resistance to several commercially available drugs. The STO cells, which have long been used as a feeder for mouse ES and embryonal carcinoma (EC) cells, were transfected with pcBIH [carrying bleomycin resistance gene (ble) and hygromycin B phosphotransferase gene (Hyg)], pcBIP [carrying ble and puromycin resistance gene (puro)], or pcBSN [carrying ble and neomycin resistance gene (neo)]. The resulting stably transfectants (termed SHB for pcBIH, SPB for pcBIP, and SNB for pcBSN) exhibited bleomycin/hygromycin, bleomycin/puromycin, or bleomycin/neomycin, as expected. The morphology of these cells passaged over 18 generations was indistinguishable from that of parental STO cells. Of isolated clones, the SHB3, SPB3, and SNB2 clones successfully supported the growth of mouse ES cells in an undifferentiated state, when coculture was performed. PCR analysis revealed the presence of the selective markers in these clones, as expected. These SHB3, SPB3, and SNB2 cells will thus be useful for the acquisition and maintenance of genetically manipulated ES/iPS cells.

    1988-03-01

    Fusion is an essentially inexhaustible source of energy that has the potential for economically attractive commercial applications with excellent safety and environmental characteristics. The primary focus for the fusion-energy development program is the generation of centralstation electricity. Fusion has the potential, however, for many other applications. The fact that a large fraction of the energy released in a DT fusion reaction is carried by high-energy neutrons suggests potentially unique applications. These include breeding of fissile fuels, production of hydrogen and other chemical products, transmutation or “burning” of various nuclear or chemical wastes, radiation processing of materials, production of radioisotopes, food preservation, medical diagnosis and medical treatment, and space power and space propulsion. In addition, fusion R&D will lead to new products and new markets. Each fusion application must meet certain standards of economic and safety and environmental attractiveness. For this reason, economics on the one hand, and safety and environment and licensing on the other hand, are the two primary criteria for setting long-range commercial fusion objectives. A major function of systems analysis is to evaluate the potential of fusion against these objectives and to help guide the fusion R&D program toward practical applications. The transfer of fusion technology and skills from the national laboratories and universities to industry is the key to achieving the long-range objective of commercial fusion applications.

    Cells derived from embryonic mouse STO cell lines differentiate into hepatocytes when transplanted into the livers of nonimmunosuppressed dipeptidylpeptidase IV (DPPIV)-negative F344 rats. Within 1 day after intrasplenic injection, donor cells moved rapidly into the liver and were found in intravascular and perivascular sites; by 1 month, they were intrasinusoidal and also integrated into hepatic plates with approximately 2% efficiency and formed conjoint bile canaliculi. Neither donor cell proliferation nor host inflammatory responses were observed during this time. Detection of intrahepatic mouse COX1 mitochondrial DNA and mouse albumin mRNA in recipient rats indicated survival and differentiation of donor cells for at least 3 months. Mouse COX1 targets were also detected intrahepatically 4-9 weeks after STO cell injection into nonimmunosuppressed wild-type rats. In contrast to STO-transplanted rats, mouse DNA or RNA was not detectable in untreated or mock-transplanted rats or in rats injected with donor cell DNA. In cultured STO donor cells, DPPIV and glucose-6-phosphatase activities were observed in small clusters; in contrast, mouse major histocompatibility complex class I H-2Kq, H-2Dq, and H-2Lq and class II I-Aq markers were undetectable in vitro before or after interferon gamma treatment. Together with H-2K allele typing, which confirmed the Swiss mouse origin of the donor cells, these observations indicate that mouse-derived STO cell lines can differentiate along hepatocytic lineage and engraft into rat liver across major histocompatibility barriers.

    The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine the feasibility of utilizing widespread current consumer-based technology to assist in distributing appropriate videos for objective evaluation. Videos from residents were recorded via a direct connection from the camera processor via an S-video output via a cable into a hub to connect to a standard laptop computer via a universal serial bus (USB) port. A standard consumer-based video editing program was utilized to capture the video and record in appropriate format. We utilized mp4 format, and depending on the size of the file, the videos were scaled down (compressed), their format changed (using a standard video editing program), or sliced into multiple videos. Standard available consumer-based programs were utilized to convert the video into a more appropriate format for handheld personal digital assistants. In addition, the videos were uploaded to a social networking website and video sharing websites. Recorded cases of laparoscopic cholecystectomy in a porcine model were utilized. Compression was required for all formats. All formats were accessed from home computers, work computers, and iPhones without difficulty. Qualitative analyses by four surgeons demonstrated appropriate quality to grade for these formats. Our preliminary results show promise that, utilizing consumer-based technology, videos can be easily distributed to surgeons to grade via GOALS via various methods. Easy accessibility may help make evaluation of resident videos less complicated and cumbersome.

  20. Automated Micro-Object Detection for Mobile Diagnostics Using Lens-Free Imaging Technology

    2016-05-01

    Full Text Available Lens-free imaging technology has been extensively used recently for microparticle and biological cell analysis because of its high throughput, low cost, and simple and compact arrangement. However, this technology still lacks a dedicated and automated detection system. In this paper, we describe a custom-developed automated micro-object detection method for a lens-free imaging system. In our previous work (Roy et al., we developed a lens-free imaging system using low-cost components. This system was used to generate and capture the diffraction patterns of micro-objects and a global threshold was used to locate the diffraction patterns. In this work we used the same setup to develop an improved automated detection and analysis algorithm based on adaptive threshold and clustering of signals. For this purpose images from the lens-free system were then used to understand the features and characteristics of the diffraction patterns of several types of samples. On the basis of this information, we custom-developed an automated algorithm for the lens-free imaging system. Next, all the lens-free images were processed using this custom-developed automated algorithm. The performance of this approach was evaluated by comparing the counting results with standard optical microscope results. We evaluated the counting results for polystyrene microbeads, red blood cells, and HepG2, HeLa, and MCF7 cells. The comparison shows good agreement between the systems, with a correlation coefficient of 0.91 and linearity slope of 0.877. We also evaluated the automated size profiles of the microparticle samples. This Wi-Fi-enabled lens-free imaging system, along with the dedicated software, possesses great potential for telemedicine applications in resource-limited settings.

    Full Text Available Die radiale extrakorporale Stoßwellentherapie (rESWT stellt eine alternative Behandlungsform zur Therapie der chronischen Enthesiopathien dar. Zahlreiche klinische Studien konnten die hohe Effektivität der rESWT bei fehlenden Nebenwirkungen zeigen. Neben den etablierten Indikationen Tennisellenbogen und Fersensporn konnten auch bei der Behandlung der chronischen Tendinitis calcarea der Schulter und beim Patellaspitzensyndrom gute klinische Ergebnisse erreicht werden. Als eine neue Indikation der rESWT stellt sich die Triggerpunktbehandlung bei muskulären Erkrankungen in der Orthopädie dar. Hier liegen erste Ergebnisse über erfolgreiche Anwendungen bei chronischen Kopf-, Nacken- und LWS-Schmerzen vor. Auch wenn zahlreiche klinische Studien einen erfolgreichen Einsatz der rESWT zeigen konnten, bleibt die Methode bis heute ohne Wirksamkeitsnachweis. Fehlende klinisch relevante Nebenwirkungen bei guten Ergebnissen lassen den Einsatz der rESWT sinnvoll erscheinen. Es bleibt aber die Notwendigkeit, hochwertige Studien durchzuführen, um den Stellenwert der rESWT im klinischen Einsatz beurteilen zu können. Unter Verwendung der radialen Applikationstechnik können Stoßwellen bis zu einer Energieflußdichte von 0,16 mJ/mm2 erreicht werden.

    In the framework of WLCG, Tier-1s need to manage large volumes of data ranging in the PB scale. Moreover they need to be able to transfer data, from CERN and with the other centres (both Tier-1s and Tier-2s) with a sustained throughput of the order of hundreds of MB/s over the WAN offering at the same time a fast and reliable access also to the computing farm. In order to cope with these challenging requirements, at INFN Tier-1 we have adopted a storage model based on StoRM/GPFS/TSM for the D1T0 and D1T1 Storage Classes and on CASTOR for the D0T1. In this paper we present the results of the commissioning tests of this system for the ATLAS experiment reproducing the real production case with a full matrix transfer from the Tier-0 and with all the other involved centres. Noticeably also the new approach of direct file access from farm to data is covered showing positive results. GPFS/StoRM has also been sucessfully deployed, configured and commissioned as storage solution for an ATLAS INFN Tier-2, specifically the one of Milano. The results are shown and discussed in this paper together with the ones obtained for the Tier-1.

    There is an increasing demand for high-resolution recording of in situ underwater cultural heritage. Reflectance transformation imaging (RTI) has a proven track record in terrestrial contexts for acquiring high-resolution diagnostic data at small scales. The research presented here documents the first adaptation of RTI protocols to the subaquatic environment, with a scuba-deployable method designed around affordable off-the-shelf technologies. Underwater RTI (URTI) was used to capture detail from historic shipwrecks in both the Solent and the western Mediterranean. Results show that URTI can capture submillimeter levels of qualitative diagnostic detail from in situ archaeological material. In addition, this paper presents the results of experiments to explore the impact of turbidity on URTI. For this purpose, a prototype fixed-lighting semisubmersible RTI photography dome was constructed to allow collection of data under controlled conditions. The signal-to-noise data generated reveals that the RGB channels of underwater digital images captured in progressive turbidity degraded faster than URTI object geometry calculated from them. URTI is shown to be capable of providing analytically useful object-level detail in conditions that would render ordinary underwater photography of limited use.

    We report integration of epitaxial ZnO films with Si(0 0 1) substrates using STO/TiN buffer layers. It has been demonstrated that the preferential orientation of the a-plane (112-bar 0) and c-plane (0 0 0 2) of ZnO can be controlled via deposition temperature and oxygen partial pressure. At lower substrate temperatures ZnO grows solely in the (0 0 0 2) orientation, while the (112-bar 0) orientation was dominant at high substrate temperatures and low oxygen pressures. At higher pressures, the (0 0 0 2) orientation is preferred, while (112-bar 0) becomes weaker and a (101-bar 2) ZnO appears. Epitaxial relationships have been determined from X-ray diffraction {phi}-scans and it was found that both c- and a-ZnO had two types of orientations due to the cubic symmetry of the STO buffer layer. The orientation relationship of c-ZnO on STO(0 0 1) was ZnO(0 0 0 1) -parallel STO(1 0 0); ZnO[112-bar 0] -parallel STO[1 1 0] and ZnO[1-bar 21-bar 0] -parallel STO[1-bar 10], while that of a-ZnO on STO(0 0 1) was ZnO(112-bar 0) -parallel STO(1 0 0); ZnO[112-bar 0] -parallel STO[1 1 0] and ZnO[0 0 0 2] -parallel STO[1-bar 10]. High-resolution transmission electron microscopy studies revealed atomically sharp interfaces with no reaction at the interface. Reversible d{sup 0} ferromagnetism was found to be present in both ZnO and STO layers. Our electron-energy-loss spectroscopy studies conclusively rule out the presence of any external ferromagnetic ions or impurities. Taken together, our data indicate that the ferromagnetic order in these undoped oxides might be defect mediated.

  7. How to object to radically new technologies on the basis of justice: the case of synthetic biology.

    A recurring objection to the exploration, development and deployment of radical new technologies is based on their implications with regards to social justice. In this article, using synthetic biology as an example, I explore this line of objection and how we ought to think about justice in the context of the development and introduction of radically new technologies. I argue that contrary to popular opinion, justice rarely provides a reason not to investigate, develop and introduce radical new technologies, although it may have significant implications for how they ought to be introduced. In particular I focus on the time dependency of justice objections and argue that often these function by looking only at the implications of the introduction of the technology at the point of introduction, rather than the more important long-term impact on patterns of distribution and opportunity.

    Embryonic stem cells (ESCs) can be propagated in vitro on feeder layers of mouse STO fibroblast cells. The STO cells secrete several cytokines that are essential for ESCs to maintain their undifferentiated state. In this study, we found significant growth inhibition of mouse ESCs (mESCs) cultured on STO cells infected with adenovirus containing a dominant-negative mutant form of IκB (rAd-dnIκB). This blockage of the NF-κB signal pathway in STO cells led to a significant decrease in [(3)H]thymidine incorporation and colony formation of mESCs. Expression profile of cytokines secreted from the STO cells revealed an increase in the bone morphogenetic protein4 (BMP4) transcript level in the STO cells infected with adenoviral vector encoding dominant negative IκB (rAd-dnIκB). These results suggested that the NF-κB signaling pathway represses expression of BMP4 in STO feeder cells. Conditioned medium from the rAd-dnIκB-infected STO cells also significantly reduced the colony size of mESCs. Addition of BMP4 prevented colony formation of mESCs cultured in the conditioned medium. Our finding suggested that an excess of BMP4 in the conditioned medium also inhibits proliferation of mESCs.

    The appearance of high mobility electrons at the LaAlO3/SrTiO3 (LAO/STO) interface has raised strong interest in the material science community and a lively debate on the origin of the phenomenon. In particular, in view of the large band gaps of the two bulk single crystals constituting this heterostructure, the realization of a conducting system was totally unexpected. A possible explanation is an electronic reconstruction of the interface, realizing a transfer of electrons from the LaAlO3 surface to SrTiO3 near the interface, thereby avoiding the polarization catastrophe associated with the alternating polar layers of the LaAlO3 film. The predictions of theoretical models based on this idea are quite peculiar and need to be verified by specific experiments able to address the electronic properties of the LAO/STO buried interface. Here, by using x-ray spectroscopy techniques, we show that the appearance of an electron system is correlated to the removal of the degeneracy of the titanium 3d states, and doped electrons appear in a band preferentially created by the hybridization between 3dxy states of titanium and oxygen 2px,y states. This splitting is consistent with an ordering of the Ti 3dxy orbital belonging to the TiO6 octahedra close to the interface, as theoretically proposed. However, the valence of titanium ions remains prevalently 4+, therefore other mechanisms should be also considered for the stabilization of the system.

    The mass storage challenge for the experiments at the Large Hadron Collider (LHC) is still nowadays a critical issue for the various Tier-1 computing centres and the Tier-0 centre involved in the custodial and analysis of the data produced by the experiments. In particular, the requirements for the tape mass storage systems are quite strong, amounting to about 15 PB of data produced annually that should be available for near-line access at any time. Besides the solutions already widely employed by the High Energy Physics community so far, INFN-CNAF has approched, in the last year, a solution based on the collaboration between the General Parallel File System (GPFS) and the Tivoli Storage Manager (TSM) by IBM and StoRM as Storage Resource Management (SRM) interface, developed at INFN. The new features available in GPFS version 3.2 allow in general to interface GPFS with any tape storage manager. We implemented such an interface for TSM, and we performed various performance studies on a prototype testbed system. The first StoRM/GPFS/TSM based system is already in production at CNAF for T1D1 Storage Class; it is used by the LHCb experiment. Currently we are performing new tests to exploit features implemented in the new versione of TSM 6.1. These features are focused in high performance and optimized access to the tape backend. We will describe the implementation of the interface and details of the prototype testbed for T1D0 SC and we will discuss the results of the LHCb production system.

Among these three objects, the re-search object is the most fundamental. A clear understanding of research objects helps to avoid the research blind are-as, set up the complete theoretical system of subjects, and develop specialized research methods. To determine the re-search object is also beneficial to the division of human research field and cooperation in research activities To determine the independence and maturity of Educational Technology, this paper uses historical and logical methods to analyze the research objects in the field of educational technology based on a study of its theoretical system and research methods. The historical method is to analyze the research content in the history of a subject, then to abstract and general-ize. The logical method is to toanalyze the attribute and the nature of a subject, then to abstract and generalize. Using historical method to analyze the research objects of Educational Technology,we can abstract out four as-pects of the research object application of visual media in education, First, from the four stages of development of for-eign educational technology, application of audio-visual media in education, the design and use of messages which control the learning process, the design, development, utilization

    This review compares the development, characteristics, validity, and reliability of two well-known quality of life (QOL) assessment tools used in patients with gastric cancer: the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach (EORTC QLQ-STO22) and the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga). A literature search was conducted using MEDLINE, EMBASE, and Cochrane CENTRAL (inception to April 2015) to identify studies that discussed the development, characteristics, validity and reliability of the EORTC QLQ-STO22 or the FACT-Ga. The QLQ-STO22 was developed with collaboration with patients, healthcare professionals and literature review and was mainly field tested in European countries. Conversely, items on the FACT-Ga were generated from interviews with patients and healthcare professionals concurrently in North America and Asia. While both modules involve a 7-day recall period and use Likert scales, the QLQ-STO22 and FACT-Ga differ in terms of QOL domain focus, quantity and presentation of items, response options, and scoring. However, both tools show good internal consistency, test-retest reliability, sensitivity to change and construct validity. In addition, both questionnaires have been internationally validated within a large sample of patients undergoing a variety of treatments, thus demonstrating their cross-cultural applicability. The EORTC QLQ-STO22 and FACT-Ga are both valid and reliable tools with unique strengths and weaknesses. Selection between instruments should consider specific patient characteristics and goals of the study.

    STO feeder cells, a line established from mouse SIM embryonic fibroblasts, have been frequently used for establishing embryonic stem cells and maintaining them in an undifferentiated state. There are some reports demonstrating that fibroblastic cells have the ability to phagocytose Gram-positive bacterium (e.g., streptococci and staphylococci). In this study, we examined the possibility that STO cells could phagocytose Streptococcus mutans (a bacteria causing tooth decay), which always contaminates cultures of primarily isolated human deciduous dental pulp cells (HDDPCs). Simple cultivation of the primary HDDPCs in the absence of STO cells allowed S. mutans to massively propagate in the medium, thus leading to an opaque medium. In contrast, there was no bacterial contamination in the cultures containing mitomycin C (MMC)-inactivated STO cells. Furthermore, STO cells indicated bacterial phagocytic activity under fluorescent microscopy with the dye pHrodo. Besides removal of contaminating bacteria, STO feeder cells allowed the HDDPCs to spread out. These data suggest that MMC-treated STO cells can be useful for propagation of HDDPCs by eliminating contaminating bacteria and by promoting cellular outgrowth.

    Properties of solid oxide fuel cell, catalysts etc. is dependent on the distribution and transport behavior of oxygen ions. In this study, we observe the dynamics of vacancy ordering in LaCoO3/SrTiO3 (LCO/STO) superlattice and LCO films using high angle annular dark field and annular bright field (ABF) STEM. Vo ordering was directly observed by tracking interatomic spacings, withs nucleation, propagation and interaction of different Vo nuclei demonstrated. Moreover, ABF images show that on 1-D (110) vacancy channels form in the depleted layers.In the case for superlattice, very small contribution of vacancy injection was observed. When this approach is applied to 15 u.c. LCO film, however, a sequence of different phases is observed, starting from disordered perovskite LaCoO3-x to a brownmillerite La3Co3O8-x to eventually brownmillerite La2Co2O5-x. Kinetics of the ordering and vacancy injection, as well as implications for beam-driven phase-transformation at an atomic scale, will be discussed.

  5. STO and GTO field-induced polarization functions for H to Kr.

    2003-10-01

    Field-induced polarization (FIP) functions were proposed over two decades ago to improve the accuracy of calculated response properties, and the FIP functions in GTO form for H and C to F were tested on small molecules, with encouraging results. The concept of FIP is now extended to all atoms up to Kr. New simplifying approximations for the description of asymptotic highest occupied atomic orbitals (HOAOs) are introduced in this study. They provide the basis for STO and GTO exponents of a complete set of FIP functions from H to Kr, which are both listed for the convenience of the users. Tests on the polarizabilities of a series of atoms and molecules demonstrate that addition of the FIP basis functions to a series of standard basis sets drastically improves the performance of all these basis sets compared to converged results. Moreover, the byproduct of this study (approximate asymptotic HOAOs) provides information for the construction of accurate basis sets for long-range ground state properties.

    Recently, human embryonic stem (hES) cells have become very important resources for basic research on cell replacement therapy and other medical applications. The purpose of this study was to test whether pluripotent hES cell lines could be successfully derived from frozen-thawed embryos that were destined to be discarded after 5 years in a routine human IVF-embryo transfer programme and whether an STO cell feeder layer can be used for the culture of hES cells. Donated frozen embryos (blastocysts or pronuclear) were thawed, and recovered or in vitro developed blastocysts were immunosurgically treated. All inner cell masses were cultured continuously on an STO cell feeder layer and then presumed hES cell colonies were characterized. Seven and two cell lines were established from frozen-thawed blastocysts (7/20, 35.0%) and pronuclear stage embryos (2/20, 10.0%), respectively. The doubling time of hES cells on the immortal STO cell feeder layer was approximately 36 h, similar to that of cells grown using fresh mouse embryonic fibroblast (MEF) feeder conditions. Subcultured hES cell colonies showed strong positive immunostaining for alkaline phosphatase, stage-specific embryonic antigen-4 (SSEA-4) and tumour rejection antigen 1-60 (TRA1-60) cell surface markers. Also, the hES colonies retained normal karyotypes and Oct-4 expression in prolonged subculture. When in vitro differentiation of hES cells was induced by retinoic acid, three embryonic germ layer cells were identified by RT-PCR or indirect immunocytochemistry. This study indicates that establishment of hES cells from frozen-thawed blastocysts minimizes the ethical problem associated with the use of human embryos in research and that the STO cell feeder layer can be used for the culture of hES cells.

    Embryonic mouse STO (S, SIM; T, 6-thioguanine resistant; O, ouabain resistant) and 3(8)21-enhanced green fluorescent protein (EGFP) cell lines exhibit long-term survival and hepatic progenitor cell behaviour after xenogeneic engraftment in non-immunosuppressed inbred rats, and were previously designated major histocompatibility complex (MHC) class I- and class II-negative lines. To determine the molecular basis for undetectable MHC determinants, the expression and haplotype of H-2K, H-2D, H-2L and I-A proteins were reassessed by reverse transcriptase-polymerase chain reaction (RT-PCR), cDNA sequencing, RNA hybridization, immunoblotting, quantitative RT-PCR (QPCR), immunocytochemistry and flow cytometry. To detect cell differentiation (CD) surface antigens characteristic of stem cells, apoptotic regulation or adaptive immunity that might facilitate progenitor cell status or immune privilege, flow cytometry was also used to screen untreated and cytokine [interferon (IFN)-gamma]-treated cultures. Despite prior PCR genotyping analyses suggestive of H-2q haplotypes in STO, 3(8)21-EGFP and parental 3(8)21 cells, all three lines expressed H-2K cDNA sequences identical to those of d-haplotype BALB/c mice, as well as constitutive and cytokine-inducible H-2K(d) determinants. In contrast, apart from H-2L(d[LOW]) display in 3(8)21 cells, H-2Dd, H-2Ld and I-Ad determinants were undetectable. All three lines expressed constitutive and cytokine-inducible CD34; however, except for inducible CD117([LOW]) expression in 3(8)21 cells, no expression of CD45, CD117, CD62L, CD80, CD86, CD90.1 or CD95L/CD178 was observed. Constitutive and cytokine-inducible CD95([LOW]) expression was detected in STO and 3(8)21 cells, but not in 3(8)21-EGFP cells. MHC (class I(+[LOW])/class II-) and CD (CD34+/CD80-/CD86-/CD95L-) expression patterns in STO and STO cell-derived progenitor cells resemble patterns reported for human embryonic stem cell lines. Whether these patterns reflect associations with

    The development of a stem cell culture system would expedite our understanding of the biology of tissue regeneration. Spermatogonial stem cell (SSC) is the foundation for lifelong male spermatogenesis and the SSC culture has been optimized continuously in recent years. However, there have been many inconveniences to reconstruct SSC self-renewal and proliferation in vitro, such as the frequent refreshment of recombinant cytokines, including GDNF, the essential growth factor for SSC maintenance. In the present study, we observed that both STO and MEF cells, which were previously used as feeders for SSC growth, did not express GDNF, but a GDNF-expressing STO feeder could support undifferentiated mouse spermatogonia propagation in vitro for three months without the refreshment of recombinant growth factor GDNF. The cell morphology, growth rate and SSC-associated gene expression remained identical to the SSCs cultured using previous methods. The transplantation of SSCs growing on these GDNF-expressing STO feeders could generate extensive colonies of spermatogenesis in recipient testes, functionally validating the stemness of these cells. Collectively, our data indicated that the further modification of feeder cells might facilitate the self-renewal and propagation of SSCs in vitro.

    Topological insulators (TIs) are new states of quantum matter in which the spin-momentum-locked surface states reside in the bulk insulating gap and have triggered extensive investigations on fundamental properties and potential applications. Herein, we report scalable, broadband photovoltaic detectors based on the topological insulator Sb2Te3/strontium titanate (STO) heterostructure. Large-scale (2 mm × 5 mm), high crystalline quality p-type Sb2Te3 films were fabricated on an n-type STO substrate by the molecular beam epitaxy (MBE) method. The Sb2Te3/STO heterostructures exhibited pronounced photovoltaic behavior in a wide range of temperatures as a result of a strong built-in field at the hetero-interface. Superior performances of broadband (from visible to infrared, 405 nm-1550 nm) and ultrafast (rise time ∼30 μs, fall time ∼95 μs) photoresponses were achieved under ambient conditions. The prominent repeatability and stability indicated that our photodetectors can operate effectively in harsh circumstances. These results show that stacking the topological insulator thin films on a strongly correlated oxide substrate using the MBE approach holds great promise for high performance optoelectronic applications.

    The inheritance of extreme resistance to PVY (Ry (sto)) by a single dominant locus was confirmed by obtaining a 1:1 segregation ratio in a virus inoculation test with 28 resistant (Ryry) to 29 susceptible (ryry) anther culture-derived dihaploid lines (2n=2x=24) from cv. "Assia" (2n=4x=48) having extreme resistance derived from Solanum stoloniferum in simplex constitution (Ryryryry). Twelve Ry (sto) markers selected in AFLP assays using bulked segregant analysis were applied to 106 tested potato cultivars from Germany, The Netherlands and Poland and 19 potato cultivars were identified by these markers as extremely resistant to PVY in alignment with phenotypic data. The locus for extreme resistance (Ry (sto)) to PVY was mapped on chromosome XII co-segregating with the SSR marker STM 0003. The utility of anther-culture derived dihaploid potatoes for genetic marker development was demonstrated. Marker transferability from diploids to tetraploids provides an optimistic potential for marker-assisted selection in potato breeding programs.

    2014-01-01

    The Internet of Things (IoT) usually refers to a world-wide network of interconnected heterogeneous objects (sensors, actuators, smart devices, smart objects, RFID, embedded computers, etc) uniquely addressable, based on standard communication protocols. Beyond such a definition, it is emerging a new definition of IoT seen as a loosely coupled, decentralized system of cooperating smart objects (SOs). A SO is an autonomous, physical digital object augmented with sensing/actuating, processing, storing, and networking capabilities. SOs are able to sense/actuate, store, and interpret information created within themselves and around the neighbouring external world where they are situated, act on their own, cooperate with each other, and exchange information with other kinds of electronic devices and human users. However, such SO-oriented IoT raises many in-the-small and in-the-large issues involving SO programming, IoT system architecture/middleware and methods/methodologies for the development of SO-based applica...

    Development and virtual representation of 3D models of Cultural Heritage (CH) objects has triggered great interest over the past decade. The main reason for this is the rapid development in the fields of photogrammetry and remote sensing, laser scanning, and computer vision. The advantages of using 3D models for restoration, preservation, and documentation of valuable historical and architectural objects have been numerously demonstrated by scientists in the field. Moreover, 3D model visualization in virtual reality has been recognized as an efficient, fast, and easy way of representing a variety of objects worldwide for present-day users, who have stringent requirements and high expectations. However, the main focus of recent research is the visual, geometric, and textural characteristics of a single concrete object, while integration of large numbers of models with additional information-such as historical overview, detailed description, and location-are missing. Such integrated information can be beneficial, not only for tourism but also for accurate documentation. For that reason, we demonstrate in this paper an integration of high-resolution spherical panoramas, a variety of maps, GNSS, sound, video, and text information for representation of numerous cultural heritage objects. These are then displayed in a web-based portal with an intuitive interface. The users have the opportunity to choose freely from the provided information, and decide for themselves what is interesting to visit. Based on the created web application, we provide suggestions and guidelines for similar studies. We selected objects, which are located in Bulgaria-a country with thousands of years of history and cultural heritage dating back to ancient civilizations. The methods used in this research are applicable for any type of spherical or cylindrical images and can be easily followed and applied in various domains. After a visual and metric assessment of the panoramas and the evaluation of

    Vixen is a collection of enabling technologies for uninhibited distributed object computing. In the Spring of 1995 when Vixen was proposed, it was an innovative idea very much ahead of its time. But today the technologies proposed in Vixen have become standard technologies for Enterprise Computing. Sun Microsystems J2EE/EJB specifications, among others, are independently proposed technologies of the Vixen type. I have brought Vixen completely under the J2EE standard in order to maximize interoperability and compatibility with other computing industry efforts. Vixen and the Enterprise JavaBean (EJB) Server technologies are now practically identical; OIL, another Vixen technology, and the Java Messaging System (JMS) are practically identical; and so on. There is no longer anything novel or patentable in the Vixen work performed under this grant. The above discussion, notwithstanding, my independent development of Vixen has significantly helped me, my university, my students and the local community. The undergraduate students who worked with me in developing Vixen have enhanced their expertise in what has become the cutting edge technology of their industry and are therefore well positioned for lucrative employment opportunities in the industry. My academic department has gained a new course: "Multi-media System Development", which provides a highly desirable expertise to our students for employment in any enterprise today. The many Outreach Programs that I conducted during this grant period have exposed local Middle School students to the contributions that NASA is making in our society as well as awakened desires in many such students for careers in Science and Technology. I have applied Vixen to the development of two software packages: (a) JAS: Joshua Application Server - which allows a user to configure an EJB Server to serve a J2EE compliant application over the world wide web; (b) PCM: Professor Course Manager: a J2EE compliant application for configuring a

    Hewlett-Packard Laboratories, 1501 Page Mill Road, Palo Alto, CA 94304, USA Introduction The USENIX Conference on Object-Oriented Technologies and Systems (COOTS) is held annually in the late spring. The conference evolved from a set of C++ workshops that were held under the auspices of USENIX, the first of which met in 1989. Given the growing diverse interest in object-oriented technologies, the C++ focus of the workshop eventually became too narrow, with the result that the scope was widened in 1995 to include object-oriented technologies and systems. COOTS is intended to showcase advanced R&D efforts in object-oriented technologies and software systems. The conference emphasizes experimental research and experience gained by using object-oriented techniques and languages to build complex software systems that meet real-world needs. COOTS solicits papers in the following general areas: application of, and experiences with, object-oriented technologies in particular domains (e.g. financial, medical, telecommunication); the architecture and implementation of distributed object systems (e.g. CORBA, DCOM, RMI); object-oriented programming and specification languages; object-oriented design and analysis. The 4th meeting of COOTS was held 27 - 30 April 1998 at the El Dorado Hotel, Santa Fe, New Mexico, USA. Several tutorials were given. The technical program proper consisted of a single track of six sessions, with three paper presentations per session. A keynote address and a provocative panel session rounded out the technical program. The program committee reviewed 56 papers, selecting the best 18 for presentation in the technical sessions. While we solicit papers across the spectrum of applications of object-oriented technologies, this year there was a predominance of distributed, object-oriented papers. The accepted papers reflected this asymmetry, with 15 papers on distributed objects and 3 papers on object-oriented languages. The papers in this special issue are

    Concurrent object-oriented languages, particularly fine-grained approaches, reduce the difficulty of large scale concurrent programming by providing modularity through encapsulation while exposing large degrees of concurrency. Despite these programmability advantages, such languages have historically suffered from poor efficiency. This paper describes the Concert project whose goal is to develop portable, efficient implementations of fine-grained concurrent object-oriented languages. Our approach incorporates aggressive program analysis and program transformation with careful information management at every stage from the compiler to the runtime system. The paper discusses the basic elements of the Concert approach along with a description of the potential payoffs. Initial performance results and specific plans for system development are also detailed.

    Full Text Available There has been demands of context-aware systems in a hospital domain and several types of sensors have been applied as sources of medical activities. Unlike the previous passive RFID use of simply identifying objects this paper presents a system for motion detection of medical objects in a trauma bay by ranging the received signal strength indication RSSI using UHF passive RFID tags as one of those sensors that provide information on medical activities. To use passive RFID RSSI for motion detection Three different types of RSSI estimators are evaluated to process noisy RSSI and the adaptive threshold is proposed in the system to improve the resolution of detecting motion. Our system has been tested with recorded RSSI values in a laboratory and an actual trauma bay during simulated resuscitations performed by trauma teams. The proposed system has achieved 85.9 - 92.1 accuracies for most passive items that are used in a trauma bay.

    Information extraction for dominant tree group types is difficult in remote sensing image classification, howevers, the object-oriented classification method using high spatial resolution remote sensing data is a new method to realize the accurate type information extraction. In this paper, taking the Jiangle Forest Farm in Fujian Province as the research area, based on the Quickbird image data in 2013, the object-oriented method was adopted to identify the farmland, shrub-herbaceous plant, young afforested land, Pinus massoniana, Cunninghamia lanceolata and broad-leave tree types. Three types of classification factors including spectral, texture, and different vegetation indices were used to establish a class hierarchy. According to the different levels, membership functions and the decision tree classification rules were adopted. The results showed that the method based on the object-oriented method by using texture, spectrum and the vegetation indices achieved the classification accuracy of 91.3%, which was increased by 5.7% compared with that by only using the texture and spectrum.

    Full Text Available This paper proposed an algorithm to track the obstacle position and avoid the moving objects for differential driving Automatic Guided Vehicles (AGV system in industrial environment. This algorithm has several abilities such as: to detect the moving objects, to predict the velocity and direction of moving objects, to predict the collision possibility and to plan the avoidance maneuver. For sensing the local environment and positioning, the laser measurement system LMS-151 and laser navigation system NAV-200 are applied. Based on the measurement results of the sensors, the stationary and moving obstacles are detected and the collision possibility is calculated. The velocity and direction of the obstacle are predicted using Kalman filter algorithm. Collision possibility, time, and position can be calculated by comparing the AGV movement and obstacle prediction result obtained by Kalman filter. Finally the avoidance maneuver using the well known tangent Bug algorithm is decided based on the calculation data. The effectiveness of proposed algorithm is verified using simulation and experiment. Several examples of experiment conditions are presented using stationary obstacle, and moving obstacles. The simulation and experiment results show that the AGV can detect and avoid the obstacles successfully in all experimental condition.

    To investigate the effect of herba schizonepetae volatile oil (STO) on the activity of 5-lipoxygenase (5-LO), so as to elucidate its mechanisms of anti-inflammatory action which is related to the arachidonic acid (AA) metabolism. Thoracic cavity leukocytes from the pleurisy model rat induced by injecting 1%-carrageenan into the pleural cavity were collected. Then 0. 4 mL cell suspension including 2 x 10(7) cells per millilitre were used as the reaction system in vitro. STO in different concentrations (final concentration 0.011, 0.022, 0.043, 0.087, 0.179, 0.255, 0.364 g x L(-1)), zileuton (final concentration 0.625 x 10(-3) g x L(-1)), and DMSO in the same volume were added into the reaction tube respectively. The reaction tubes were incubated at 37 degrees C for 20 min and CaCl2 (final concentration 2 mmol x L(-1)), MgCl2 (final concentration 0.5 mmol x L(-1)), exogenous AA (final concentration 200 micromol x L(-1)) and A23187 (final concentration 5 micromol x L(-1)) were added in turns during this period. The reaction tubes were mixed and continuously incubated at 37 degrees C for 30 min. After terminating reaction by adding methanol, the metabolites of 5-LO, leukotriene B4 (LTB4) and 5-hydroxy-6, 8, 11, 14-eicosatetraenoic acid (5-HETE), were extracted, separated and detected by means of RP-HPLC. Compared with control group, STO significantly inhibited the biosynthesis of LTB4 and 5-HETE at final concentration between 0. 022 g x L(-1) and 0.364 g x L(-1) (P STO can inhibited the activity of 5-LO, which is an important enzyme of AA metabolism, in rat thoracic cavity leukocytes in a dose-dependent manner in vitro. It is suggested that the mechanism of anti-inflammatory action of STO is related to its inhibiting the activity of 5-LO and decreasing the level of major inflammatory mediators LTB4.

    Position and orientation estimation of the object, which can be widely applied in the fields as robot navigation, surgery, electro-optic aiming system, etc, has an important value. The monocular vision positioning algorithm which is based on the point characteristics is studied and new measurement method is proposed in this paper. First, calculate the approximate coordinates of the five reference points which can be used as the initial value of iteration in the camera coordinate system according to weakp3p; Second, get the exact coordinates of the reference points in the camera coordinate system through iterative calculation with the constraints relationship of the reference points; Finally, get the position and orientation of the object. So the measurement model of monocular vision is constructed. In order to verify the accuracy of measurement model, a plane target using infrared LED as reference points is designed to finish the verification of the measurement method and the corresponding image processing algorithm is studied. And then The monocular vision experimental system is established. Experimental results show that the translational positioning accuracy reaches +/-0.05mm and rotary positioning accuracy reaches +/-0.2o .

    Xing, Suxia; Liu, Peng

    In this effort, we proposed an new image fusion technique, utilizing Renyi entropy's object extraction and Non-Subsampled Contourlet Transform (NSCT), for improved visible effect of the image. NSCT is a multiscale transform method, it is a shift-invariant, linear phase, ``true" two-dimensional transform that can decomposes an image into any directional sub-images to capture the intrinsic geometrical structure. In this paper we decompose visible image into 21, 22, and 23 directional sub-images at three different level respectively. Image enhancement is performed at the decomposition level and fused. Renyi entropy is a generalized information entropy. Infrared image can be divided into two parts of the object and the background through the maximum value of Renyi entropy. Image fusion is performed after NSCT and Renyi entropy. The fused image has significantly improved brightness and higher contrast than other images. In order to evaluate the proposed method, information entropy (IE), standard deviation (STD), spatial frequency (SF) and mutual information (MI) are adopted to compare with Laplace, wavelet, and NSCT et al. Results are shown that all evaluation value of the proposed method is higher than that of other methods, and it is a better image fusion method.

    Exposure to alcohol marketing within alcohol retailers has been associated with higher rates of childhood drinking, brand recognition, and marketing recall. This study aimed to objectively measure children's everyday exposure to alcohol marketing within supermarkets. Children aged 11-13 (n = 167) each wore a wearable camera and GPS device for four consecutive days. Micro-spatial analyses were used to examine exposures within supermarkets. In alcohol retailing supermarkets (n = 30), children encountered alcohol marketing on 85% of their visits (n = 78). Alcohol marketing was frequently near everyday goods (bread and milk) or entrance/exit. Alcohol sales in supermarkets should be banned in order to protect children from alcohol marketing.

    Demand among large office buildings for the energy-saving benefits of the HVAC (Heating, Ventilating and Air-Conditioning) System are increasing as more and more people become concerned with global environmental issues. However, immoderate measures taken in the interest of energy conservation may encroach on the thermal comfort and productivity level of office workers. Building management should satisfy both indoor thermal comfort and energy conservation while adapting to the many regulatory, social, climate, and other changes that occur during the lifespan of the building. This paper demonstrates how optimal control of the HVAC system, based on data modeling and the multi-objective optimal method, achieves an efficient equilibrium between thermal comfort and energy conservation.

    Science.gov (United States)

    Paul, Norbert W

    2009-09-01

    Since decades, scientific change has been interpreted in the light of paradigm shifts and scientific revolutions. The Kuhnian interpretation of scientific change however is now more and more confronted with non-disciplinary thinking in both, science and studies on science. This paper explores how research in biomedicine and the life sciences can be characterized by different rationalities, sometimes converging, sometimes contradictory, all present at the same time with varying ways of influence, impact, and visibility. In general, the rationality of objects is generated by fitting new objects and findings into a new experimental context. The rationality of hypotheses is a move towards the construction of novel explanatory tools and models. This is often inseparable meshing with the third, the technological rationality, in which a technology-driven, self-supporting and sometimes self-referential refinement of methods and technologies comes along with an extension into other fields. During the second and the third phase, the new and emerging fields tend to expand their explanatory reach not only across disciplinary boundaries but also into the social sphere, creating what has been characterized as "exceptionalism" (e.g. genetic exceptionalism or neuro-exceptionalism). Finally, recent biomedicine and life-sciences reach a level in which experimental work becomes more and more data-driven because the technologically constructed experimental systems generate a plethora of findings (data) which at some point start to blur the original hypotheses. For the rationality of information the materiality of research practices becomes secondary and research objects are more and more getting out of sight. Finally, the credibility of science as a practice becomes more and more dependent on consensus about the applicability and relevance of its results. The rationality of interest (and accountability) has become more and more characteristic for a research process which is no longer

    Gates, W. R.

    1982-07-01

    The economic and social benefits of developing cost competitive solar thermal technologies (STT) were assessed. The analysis was restricted to STT in electric applications for 16 high insolation/high energy price states. Three fuel price scenarios and three 1990 STT system costs were considered, reflecting uncertainty over fuel prices and STT cost projections. After considering the numerous benefits of introducing STT into the energy market, three primary benefits were identified and evaluated: (1) direct energy cost savings were estimated to range from zero to $50 billion; (2) oil imports may be reduced by up to 9 percent, improving national security; and (3) significant environmental benefits can be realized in air basins where electric power plant emissions create substantial air pollution problems. STT research and development was found to be unacceptably risky for private industry in the absence of federal support. The normal risks associated with investments in research and development are accentuated because the OPEC cartel can artificially manipulate oil prices and undercut the growth of alternative energy sources.

    Species” of military aircraft, commercial aircraft and private cars have been chosen in our analysis as illustrations of the fruitfulness of the “ holistic” approach. The obtained data show that both commercial “ species” exhibit similar “ survival dynamics” in compare with those of the military species of aircraft: lifetime distributions were found to be Weibull distributions for all “ species” however for commercial vehicles, the shape parameters were a little higher than 2, and scale parameters were 19.8 years (aircraft) and 21.7 (cars) whereas for military aircraft, the shape parameters were much higher and the mean time to failure much longer. The difference between the lifetime characteristics of the “ species” can be attributed to the differences in the social, operational, economic and safety-and-reliability requirements and constraints. The obtained information can be used to make tentative predictions for the most likely trends in the given field of vehicular technology. The following major conclusions can be drawn from our analysis: 1) The suggested concept based on the use of HLPFs reflects the current state and the general perceptions in the given field of engineering, including aerospace technologies, and allows for all the inherent and induced factors to be taken into account: any type of failures, usage profiles, economic factors, environmental conditions, etc. The concept requires only very general input data for the entire population. There is no need for the less available information about individual articles. 2) Failure modes are not restricted to the physical type of failures and include economic, cultural or social effects. All possible causes, which might lead to making a decision to terminate the use of a particular type

  13. Eye Tracking Research and Technology: Towards Objective Measurement of Data Quality.

    Two methods for objectively measuring eye tracking data quality are explored. The first method works by tricking the eye tracker to detect an abrupt change in the gaze position of an artificial eye that in actuality does not move. Such a device, referred to as an artificial saccade generator, is shown to be extremely useful for measuring the temporal accuracy and precision of eye tracking systems and for validating the latency to display change in gaze contingent display paradigms. The second method involves an artificial pupil that is mounted on a computer controlled moving platform. This device is designed to be able to provide the eye tracker with motion sequences that closely resemble biological eye movements. The main advantage of using artificial motion for testing eye tracking data quality is the fact that the spatiotemporal signal is fully specified in a manner independent of the eye tracker that is being evaluated and that nearly identical motion sequence can be reproduced multiple times with great precision. The results of the present study demonstrate that the equipment described has the potential to become an important tool in the comprehensive evaluation of data quality.

    The importance of automated prism tracking is increasingly triggered by the rising automation of total station measurements in machine control, monitoring and one-person operation. In this article we summarize and explain the different techniques that are used to coarsely search a prism, to precisely aim at a prism, and to identify whether the correct prism is tracked. Along with the state-of-the-art review, we discuss and experimentally evaluate possible improvements based on the image data of an additional wide-angle camera which is available for many total stations today. In cases in which the total station's fine aiming module loses the prism, the tracked object may still be visible to the wide-angle camera because of its larger field of view. The theodolite angles towards the target can then be derived from its image coordinates which facilitates a fast reacquisition of the prism. In experimental measurements we demonstrate that our image-based approach for the coarse target search is 4 to 10-times faster than conventional approaches.

    We recently developed STO-609, a selective inhibitor of Ca(2+)/calmodulin-dependent protein kinase kinase (CaM-KK), and we demonstrated that CaM-KK beta is more sensitive to STO-609 than the CaM-KK alpha isoform (Tokumitsu H., Inuzuka H., Ishikawa Y., Ikeda M., Saji I., and Kobayashi R. (2002) J. Biol. Chem. 277, 15813-15818). By using catalytic chimera and point mutants of both isoforms, we demonstrated that Val(269) in CaM-KK beta/Leu(233) in CaM-KK alpha confers a distinct sensitivity ( approximately 10-fold) to STO-609 on CaM-KK isoforms. Various mutations of Val(269) in CaM-KK beta indicate that substitution by hydrophobic residues with bulky side chains significantly decreases drug sensitivity and that the V269F mutant is the most effective drug-resistant enzyme ( approximately 80-fold higher IC(50) value). These findings are consistent with a result obtained with a full-length mutant expressed in COS-7 cells. Furthermore, suppression of CaM-KK-mediated CaM-KIV activation in transfected HeLa cells by STO-609 treatment was completely abolished by the co-expression of the CaM-KK beta V269F mutant. Based on the results that the distinct sensitivity of CaM-KK isoforms to STO-609 is because of a single amino acid substitution (Val/Leu) in the ATP-binding pocket, we have generated an STO-609-resistant CaM-KK mutant, which might be useful for validating the pharmacological effects and specificity of STO-609 in vivo.

    In attempts to recharacterize several markers of putative rat liver progenitor cells, single-stage reverse transcription-polymerase chain reaction (RT-PCR) analyses failed to confirm the reported immunochemical detection of albumin, alpha(1)-fetoprotein, and cytochrome P450-1A2 in the clonal line, 3(8)#21, and the cloned derivative, 3(8)#21-EGFP (enhanced green fluorescent protein). Undetectable expression occurred whether or not both lines were cultured on or off feeder layers of gamma-irradiated mouse embryonic STO (SIM [Sandoz inbred Swiss mouse] thioguanine-resistant ouabain-resistant) cells. PCR amplification of liver progenitor cell chromosomal (rat and mouse Pigr, rat INS1, mouse INS2) and mitochondrial (rat and mouse COX1) genes revealed only mouse sequences. Further analyses of rat and mouse COX1 sequences in cells from untampered storage vials of all 11 reported liver progenitor cell lines and strains revealed only mouse sequences. In addition, uniquely similar metaphase spreads were observed in STO, 3(8)#21, and 3(8)#21-EGFP cells. The combined results suggest that the previously reported "rat" liver progenitor cell lines were most likely generated during early derivation in cell culture from gamma-radiation-resistant or ineffectively irradiated mouse STO cells used as the feeder layers. These findings reveal new types of artifacts encountered in cocultures of tissue progenitor cells and feeder layer cell lines, and they sound a cautionary note: phenotypic and genotypic properties of feeder layers should be well-characterized before and during coculture with newly derived stem cells and clonal derivatives.

    Ca2+/calmodulin (CaM)-dependent protein kinase (CaMK) kinase (CaMKK) is a member of the CaMK cascade that mediates the response to intracellular Ca2+ elevation. CaMKK phosphorylates and activates CaMKI and CaMKIV, which directly activate transcription factors. In this study, we determined the 2.4 Å crystal structure of the catalytic kinase domain of the human CaMKKβ isoform complexed with its selective inhibitor, STO-609. The structure revealed that CaMKKβ lacks the αD helix and that the equivalent region displays a hydrophobic molecular surface, which may reflect its unique substrate recognition and autoinhibition. Although CaMKKβ lacks the activation loop phosphorylation site, the activation loop is folded in an active-state conformation, which is stabilized by a number of interactions between amino acid residues conserved among the CaMKK isoforms. An in vitro analysis of the kinase activity confirmed the intrinsic activity of the CaMKKβ kinase domain. Structure and sequence analyses of the STO-609-binding site revealed amino acid replacements that may affect the inhibitor binding. Indeed, mutagenesis demonstrated that the CaMKKβ residue Pro274, which replaces the conserved acidic residue of other protein kinases, is an important determinant for the selective inhibition by STO-609. Therefore, the present structure provides a molecular basis for clarifying the known biochemical properties of CaMKKβ and for designing novel inhibitors targeting CaMKKβ and the related protein kinases.

    The Los Alamos Large Scale Demonstration and Deployment Project (LSDDP) in support of the US Department of Energy (DOE) Deactivation and Decommissioning Focus Area (DDFA) is identifying and demonstrating technologies to reduce the cost and risk of management of transuranic element contaminated large metal objects, i.e. gloveboxes. The previously conducted demonstrations supported characterization and ''front end'' aspects of the Los Alamos Decontamination and Volume Reduction System (DVRS) project. The first demonstration was shown to save the DVRS project approximately $200,000 per year and characterization technologies have been estimated to save DVRS a month of DVRS operation per year. In FY01 demonstrations for decontamination technologies, communication systems, and waste data collection systems have provided additional savings equivalent to another $200K per year of operation. The Los Alamos Large Scale demonstration and Deployment Project continues to provide substantial cost savings to the DVRS process in this second round of demonstrations. DVRS cost savings of $400K per year can now be counted, with additional efficiency savings of up to 30% on many tasks.

    The purpose of this study was to perform continuous StO(2) monitoring of rat island flaps during pedicle vessel occlusion using near-infrared spectroscopy (NIRS) in order to collect experimental data for StO(2) flap monitoring under optimized conditions. Twenty rats were used in this study. The 3 × 3 cm(2) epigastric skin island flaps were elevated on either side. The animals were randomly assigned to two groups; an arterial occlusion group (n = 10) and a venous occlusion group (n = 10). The StO(2) values of the flaps were observed for over 30 min for the pedicle artery or venous occlusion, followed by an additional 30 min release. The baseline StO(2) value was 78.4% ± 3.2% in the arterial occlusion group, compared to 78.5% ± 5.8% in the venous occlusion group, with no significant differences (P > 0.05). The StO(2) values decreased immediately after arterial occlusion, whereas a temporal StO(2) increase was initially observed after venous occlusion, followed by a StO(2) decrease. The StO(2) values decreased 27.3% ± 7.1% after arterial occlusion and 28.4% ± 19.1% after venous occlusion at 30 min after pedicle vessel clamping (P > 0.05). The StO(2) values were 0.4% ± 5.8% lower than baseline 30 min after arterial release (P > 0.05), while 18.9% ± 11.3% lower than baseline 30 min after venous release (P StO(2) changes in flaps with the pedicle vessel occlusion and differentiate between pedicle artery and vein occlusion. Further investigations are needed to obtain definitive evidence associated with predicting the degree of flap viability and determine the practical use of this technique. © 2015 Wiley Periodicals, Inc.

    It has previously been reported that AMP-activated protein kinase (AMPK) may be critical for hypoxic chemotransduction in carotid body type I cells. This study sought to determine the importance of the regulatory upstream kinase of AMPK, CamKKβ, in the acute response to hypoxia in isolated mouse type I cells.Initial data indicated several previously unreported artefacts associated with using the CamKKβ inhibitor STO609 and Ca(2+) imaging techniques. Most importantly Fura-2 and X-Rhod1 imaging revealed that STO609 quenched emission fluorescence even in the absence of intracellular Ca(2+) ([Ca(2+)](I)). Furthermore, STO609 (100 μM) rapidly inhibited outward macroscopic currents and this inhibition was abolished in the presence of the selective BK(Ca) inhibitor paxilline.Taken together these data suggest that ST0609 should be used with caution during Ca(2+) imaging studies as it can directly interact with Ca(2+) binding dyes. The rapid inhibitory effect of STO609 on BK(Ca) was unexpected as the majority of studies using this compound required an incubation of approximately 10 min to inhibit the kinase. Furthermore, as AMPK activation inhibits BK(Ca), inhibiting AMPK's upstream kinases would, if anything, be predicted to have the opposite effect on BK(Ca). Future work will determine if the inhibition of BK(Ca) is via CamKKβ or via an off target action of STO609 on the channel itself.

    This study aimed to compare the in vitro effects of coculture with Sertoli and SIM mouse embryo-derived thioguanine- and ouabain-resistant (STO) feeder layer cells on the efficiency of adult mouse spermatogonial stem cells (SSCs) colony formation. Sertoli and SSCs were isolated from testes, and their identity was confirmed using immunocytochemistry against Oct4, CDH1, PLZF and C-kit for SSCs and vimentin for Sertoli cells. SSCs were cultured in a simple culture system (control group) and on top of the Sertoli and STO feeder layers for 2 weeks. The number and diameter of colonies were evaluated during third, 7th, 10th and 14th day of culture, and the expression of the Oct-4, α6 and β1 integrins was assessed using quantitative RT-PCR. Significant differences were observed between the three groups, separately for each time (P < 0.05), with higher mean in number and diameter for Sertoli cells (P < 0.05). The results of RT-PCR showed higher gene expression of β1 integrin in Sertoli group, but no significant differences were observed in Oct-4 and α6 integrin gene expression among the three groups. Based the on the optimal effect of Seroli cells on the colony formation of SSCs, it is suggested to use these cells for better colonisation of SSCs. © 2011 Blackwell Verlag GmbH.

    ., 2006; Boström, 2008; Demircioğlu vd., 2006, 2009. Unlike the other grades, 9th grade physics curriculum is discussed with an understanding of “science-for-all” (MEB, 2007. In the scope of this understanding, all 9th grade students will not have to continue studying science and/or physics education in future. Thus, they will give their attention to understand physical events and relations between physical events and real life. The textbooks are used by teachers and students as a common guidance material. Additionally, the textbooks which are involved in education in the visual tools are every common, and teachers give a great importance to them. Primarily, the textbooks are offered as a source and a guide for teachers. The teachers can follow many educational activities and can control the topic sequences of the curriculum. Also they can find different teaching activities that can be used during course from the text books. Thus, one of the most important elements of a good textbook is that the book should reflect educational program very well. Therefore, it is important that the activities which are related ability and unit objectives in the physics curriculum are mentioned in 9th grade physics textbooks. The main purpose of this study is to determine the teachers’ views on the applicability of the technology design objectives in 9th grade physics curriculum. The study is carried out in the form of a case study. Semi-constructed interviews are used to collect data. The sample group is consisted of ten physics teachers in MNE (Ministry of National Education who teach in 9th grades. Four teachers are women, six are men. The teachers have an experience at least 11 years, at most 37 years. And they are between the ages of 34 and 57. Five of these ten teachers work in Anatolian High Schools, two of them work in Industrial Vocational High Schools, and one of them works in General High Schools, one of them works in Anatolian Technique High Schools and one of them works

    Calcium/calmodulin-dependent kinase kinase 2 (CaMKK2) has been implicated in the regulation of metabolic activity in cancer and immune cells, and affects whole-body metabolism by regulating ghrelin-signalling in the hypothalamus. This has led to efforts to develop specific CaMKK2 inhibitors, and STO-609 is the standardly used CaMKK2 inhibitor to date. We have developed a novel fluorescence-based assay by exploiting the intrinsic fluorescence properties of STO-609. Here, we report an in vitro binding constant of KD ∼17 nM between STO-609 and purified CaMKK2 or CaMKK2:Calmodulin complex. Whereas high concentrations of ATP were able to displace STO-609 from the kinase, GTP was unable to achieve this confirming the specificity of this association. Recent structural studies on the kinase domain of CaMKK2 had implicated a number of amino acids involved in the binding of STO-609. Our fluorescent assay enabled us to confirm that Phe(267) is critically important for this association since mutation of this residue to a glycine abolished the binding of STO-609. An ATP replacement assay, as well as the mutation of the 'gatekeeper' amino acid Phe(267)Gly, confirmed the specificity of the assay and once more confirmed the strong binding of STO-609 to the kinase. In further characterising the purified kinase and kinase-calmodulin complex we identified a number of phosphorylation sites some of which corroborated previously reported CaMKK2 phosphorylation and some of which, particularly in the activation segment, were novel phosphorylation events. In conclusion, the intrinsic fluorescent properties of STO-609 provide a great opportunity to utilise this drug to label the ATP-binding pocket and probe the impact of mutations and other regulatory modifications and interactions on the pocket. It is however clear that the number of phosphorylation sites on CaMKK2 will pose a challenge in studying the impact of phosphorylation on the pocket unless the field can develop approaches to

We use the effective Lagrangian based on the heavy quark symmetry to explore the rescattering mechanism and calculate their production ratios. Our results have shown that the production ratios for the $\\Upsilon(5S,6S) \\to \\gamma X_b$ are orders of $10^{-5}$ with reasonable cutoff parameter range $\\alpha \\simeq 2\\sim 3$. The sizeable production ratios may be accessible at the future experiments like forthcoming BelleII, which will provide important clues to the inner structures of the exotic state $X_b$.

    In this study, we have fabricated the bipolar transparent resistive random access memory (TRRAM) based in complex oxide amorphous STO films as dielectric layer grown by pulsed laser deposition (PLD) technique, and semiconducting In-Ga-Zn-O films were employed as electrode. The experimental results show that the average transmittance of the device is above 82.7% in the visible region (400-800nm). The device can be repeated more than 260 times, and the high and low resistance state can be held without obvious degradation within 5×104s. The conduction mechanisms at HRS and LRS were both attributed to the space charge limited current. And the RS mechanism is related to trapping and releasing of electrons which impact the current level though the cell for changing the resistance state.

The procedure of construction based upon the taken into account the second order of perturbation theory in the magnetic field case. Analytical form of correction functions has been obtained using the closed representation of the Green functions by the solution of nonhomogeneous Schrödinger equation for the model problem of "one-electron atom in the external uniform magnetic field". Their performance has been evaluated for the DFT level calculations carried out with a number of functionals. The test calculations of magnetic susceptibility and 1H nuclear magnetic shielding tensors demonstrated a good agreement of the calculated values with the experimental data.

    As cultural sector practice becomes increasingly dependent on digital technologies for the production, display, and dissemination of art and material heritage, it is important that those working in the sector understand the basic scientific principles underpinning these technologies and the social, political and economic implications of exploiting them. The understanding of issues in cultural heritage preservation and digital heritage begins in the education of the future stakeholders and the innovative integration of technologies into the curriculum. This paper gives an example of digital technology skills embedded into a module in the interdisciplinary UCL Bachelor of Arts and Sciences, named "Technologies in Arts and Cultural Heritage", at University College London.

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

    Arabidopsis (Arabidopsis thaliana) SALT TOLERANCE/B-BOX ZINC FINGER PROTEIN24 (STO/BBX24) is a negative regulator of the light signal transduction that localizes to the nucleus of plant cells and interacts with CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) in the yeast (Saccharomyces cerevisiae) two-hybrid system. The protein contains two B-box zinc-finger motives at the N terminus and a conserved motif at the C-terminal part required for the interaction with COP1. BBX24 accumulates during deetiolation of young seedlings in the first hours of exposure to light. However, this accumulation is transient and decreases after prolonged light irradiation. Here, we identified the amino acidic residues necessary for the nuclear import of the protein. In addition, we created mutated forms of the protein, and analyzed them by overexpression in the bbx24-1 mutant background. Our results indicate that the degradation of BBX24 occurs, or at least is initiated in the nucleus, and this nuclear localization is a prerequisite to fulfill its function in light signaling. Moreover, mutations in the region responsible for the interaction with COP1 revealed that a physical interaction of the proteins is also required for degradation of BBX24 in the light and for normal photomorphogenesis.

    Feeder cells of irradiated mouse fibroblasts are commonly used for, and are generally necessary for, the in vitro maintenance and growth of many fastidious cell types, particularly embryonic stem cells or induced pluripotent stem cells. Quantitative and semiquantitative immunoassays of conditioned media were performed to identify some of the soluble cytokines, chemokines, protein hormones, and cell matrix/adhesion molecules that are elaborated from two commonly used feeder cells, STO and CF-1. Among those quantitatively assayed, the most abundant cytokine proteins expressed by the feeder cells were activin A, hepatocyte growth factor (HGF), insulin-like growth factor 1, insulin-like growth factor 2, insulin-like growth factor binding protein (IGFBP)-6, macrophage colony-stimulating factor (a.k.a. CSF-1), and pigment epithelium-derived factor (a.k.a. serine protease inhibitor, clade F, member 1). CF-1 cells expressed ten times more activin A than STO cells and also produced larger amounts of interleukin-6 and IGFBP-2, IGFBP-3, IGFBP-4, and IGFBP-5. Conversely, STO cell produced almost ten times more HGF and five times more stem cell factor (a.k.a. c-kit ligand) than CF-1 cells. Assayed semiquantitatively, relatively large amounts of chemokines were produced by both feeder cells including fractalkine (CX3CL1), interferon-inducible protein 10 (a.k.a. CXCL10 and cytokine-responsive gene-2, CRG-2), monocyte chemotactic protein (MCP)-1 (a.k.a. CCL2 and junctional epithelium chemokine (JE), MCP-5/CCL12), keratinocyte-derived chemokine (a.k.a. CXCL1 and growth-related oncogene alpha, GROα), nephroblastoma overexpressed gene (CCN3, IGFBP-9), stromal cell-derived factor 1 (CXCL12), and serpin E1 (PAI-1). In contrast to one another, STO produced more CXCL16 than CF-1 cells, and CF-1 cell produced more MCP-5 (CCL12), macrophage inflammatory protein (MIP)-1α (CCL3), MIP-1β (CCL4), pentraxin-3 (TSG-14), and platelet factor-4 (CXCL4) than STO cells.

    Full Text Available Abstract Background Disease and treatment related events, can adversely affect the quality of life of patients with cancer. The purpose of this study was to translate and validate a gastric cancer specific health related quality of life questionnaire (EORTC QLQ-STO22 for Iranian patients suffering from gastric cancer. Methods Forward-backward procedure was applied to translate the English language version of the EORTC QLQ-STO22 into Persian (Iranian language. Then, the questionnaire and the EORTC core quality of life instrument (QLQ-C30 were administered to a sample of patients with confirmed diagnosis of gastric cancer. All patients filled in questionnaires before and after one month of treatment. Patients were divided into two groups based on intension of treatment (curative vs. palliative. Reliability and validity of the module was tested by internal consistency and known group comparisons, respectively. Results In all, 105 patients were entered into the study. Cronbach's alpha for multi-item scales (to test reliability ranged from 0.54 to 0.87. The questionnaire discriminated well between clinically distinct subgroups of patients both before and after treatment lending support to its convergent and clinical validity. Conclusion Overall, the Iranian version of the EORTC QLQ-STO22 demonstrated a good reliability and clinical validity to support its use in combination with core questionnaire in outcome studies of gastric cancer in Iran. However, using the QLQ-STO22 in a wide range of Iranian patients with gastric cancer should allow further confirmation for its psychometric properties.

    Improved metal-insulator-metal capacitor (MIMCAP) stacks with strontium titanate (STO) as dielectric sandwiched between Ru as top and bottom electrode are shown. The Ru/STO/Ru stack demonstrates clearly its potential to reach sub-20 nm technology nodes for dynamic random access memory. Downscaling of the equivalent oxide thickness, leakage current density (J{sub g}) of the MIMCAPs, and physical thickness of the STO have been realized by control of the Sr/Ti ratio and grain size using a heterogeneous TiO{sub 2}/STO based nanolaminate stack deposition and a two-step crystallization anneal. Replacement of TiN with Ru as both top and bottom electrodes reduces the amount of electrically active defects and is essential to achieve a low leakage current in the MIM capacitor.

    To validate the health-related quality of life questionnaire EORTC QLQ STO-22 for patients with gastric cancer in Peru, evaluating cultural and psychometric characteristics. The first phase consisted in measure the content and appearance validity. In the second phase, the questionnaire was applied to patients diagnosed with gastric cancer and the internal consistency, test-retest reliability, convergent validity, discriminant validity and criterion validity was determined. After performing the content and appearance validity the questions/items 31 and 39 were changed. The global Cronbach's α was 0.90 and α coefficients greater than 0.7 in the multi-item subscales was obtained. The test-retest reliability showed an overall correlation of 0.924. When analyzing the convergent and discriminant validity, the values of Pearson's "r" were higher between an item and its own subscale, than the same item with other multi-item sub-scales. The criterion validity of the EORTC QLQ STO-22 compared with the EORTC QLQ C-30 showed a positive correlation of 0.727 with items evaluating symptomatology, and a negative correlation of -0.587 when comparing with functional status items, both statistically significant. The modified questionnaire EORTC QLQ STO-22 meets the reliability and validity criteria for assessing the quality of life in patients with gastric cancer in Peru.

    Adenosine monophosphate (AMP)-activated protein kinase is a recently identified downstream target of calcium/calmodulin-dependent protein kinase kinase-beta, and is involved in the regulation of cell metabolism and cell proliferation. STO-609 is a selective antagonist of calcium/calmodulin-dependent protein kinase kinase-beta. In the present study, we found that STO-609 suppressed AMP-activated protein kinase activity, reduced expression of Akt and ERK, and increased cell apoptosis in SNU-1 and N87 cells but not normal gastric epithelial cells (CCL-241). Interestingly, we found such effects of STO-609 on gastric cancer cells were not affected after the knock-down of CaMKK-β and AMPK. In conclusion, STO-609 is an effective cytotoxic agent for gastric adenocarcinoma in vivo.

    This article presents the synthesis of results from the Stanford Energy Modeling Forum Study 27, an inter-comparison of 19 energy-economy and integrated assessment models. The study investigated the value of individual mitigation technologies such as energy intensity improvements, carbon capture and sequestration (CCS), nuclear power, solar and wind power and bioenergy for climate mitigation. Achieving atmospheric greenhouse gas concentration targets at 450 and 550 ppm CO2 equivalent requires massive greenhouse gas emissions reductions. A fragmented policy approach at the level of current ambition is inconsistent with these targets. The availability of a negative emissions technology, in most models biofuels with CCS, proved to be a key element for achieving the climate targets. Robust characteristics of the transformation of the energy system are increased energy intensity improvements and the electrification of energy end use coupled with a fast decarbonization of the electricity sector. Non-electric energy end use is hardest to decarbonize, particularly in the transport sector. Technology is a key element of climate mitigation. Versatile technologies such as CCS and bioenergy have largest value, due in part to their combined ability to produce negative emissions. The individual value of low-carbon power technologies is more limited due to the many alternatives in the sector. The scale of the energy transformation is larger for the 450 ppm than for the 550 ppm CO2e target. As a result, the achievability and the costs of the 450 ppm target are more sensitive to variations in technology variability. Mitigation costs roughly double when moving from 550 ppm to 450 ppm CO2e, but remain below 3% of GDP for most models.

    Full Text Available The purpose of this article is to apply the methodology to structure the decision problem and select an appropriate LOR architecture. This reflected in the need to invest and improve the technology for educational organizations. Selecting an appropriate infrastructure for LOR is usually a complex decision, because it has conflicting attributes. In situations of uncertainty, multi-attribute utility theory (MAUT assists in selecting the best alternative according to criteria established by the decision maker. Results demonstrated that the choice of indexing and distributing LOR (A4 is less sensitive to changes and has greater utility. According to the analysis, A4 is the option most suitable for deploying IT infrastructure in the case of application. Researchers and professional managers can assess the types of ROA architecture and replicate this decision model to find similar results.

    With the causes of perinatal brain injuries still unclear and the probable role of hemodynamic instability in their etiology, bedside monitoring of neonatal cerebral hemodynamics with standard values as a function of age are needed. In this study, we combined quantitative frequency domain near infrared spectroscopy (FD-NIRS) measures of cerebral tissue oxygenation (StO(2)) and cerebral blood volume (CBV) with diffusion correlation spectroscopy (DCS) measures of a cerebral blood flow index (CBF(ix)) to test the validity of the CBV-CBF relationship in premature neonates and to estimate cerebral metabolic rate of oxygen (rCMRO(2)) with or without the CBF(ix) measurement. We measured 11 premature neonates (28-34 weeks gestational age) without known neurological issues, once a week from one to six weeks of age. In nine patients, cerebral blood velocities from the middle cerebral artery were collected by transcranial Doppler (TCD) and compared with DCS values. Results show a steady decrease in StO(2) during the first six weeks of life while CBV remains stable, and a steady increase in CBF(ix). rCMRO(2) estimated from FD-NIRS remains constant but shows wide interindividual variability. rCMRO(2) calculated from FD-NIRS and DCS combined increased by 40% during the first six weeks of life with reduced interindividual variability. TCD and DCS values are positively correlated. In conclusion, FD-NIRS combined with DCS offers a safe and quantitative bedside method to assess CBV, StO(2), CBF, and rCMRO(2) in the premature brain, facilitating individual follow-up and comparison among patients. A stable CBV-CBF relationship may not be valid for premature neonates. 2009 Wiley-Liss, Inc.

    Ca(2+)/calmodulin (CaM)-dependent protein kinase (CaMK) kinase (CaMKK) is a member of the CaMK cascade that mediates the response to intracellular Ca(2+) elevation. CaMKK phosphorylates and activates CaMKI and CaMKIV, which directly activate transcription factors. In this study, we determined the 2.4 Å crystal structure of the catalytic kinase domain of the human CaMKKβ isoform complexed with its selective inhibitor, STO-609. The structure revealed that CaMKKβ lacks the αD helix and that the equivalent region displays a hydrophobic molecular surface, which may reflect its unique substrate recognition and autoinhibition. Although CaMKKβ lacks the activation loop phosphorylation site, the activation loop is folded in an active-state conformation, which is stabilized by a number of interactions between amino acid residues conserved among the CaMKK isoforms. An in vitro analysis of the kinase activity confirmed the intrinsic activity of the CaMKKβ kinase domain. Structure and sequence analyses of the STO-609-binding site revealed amino acid replacements that may affect the inhibitor binding. Indeed, mutagenesis demonstrated that the CaMKKβ residue Pro(274), which replaces the conserved acidic residue of other protein kinases, is an important determinant for the selective inhibition by STO-609. Therefore, the present structure provides a molecular basis for clarifying the known biochemical properties of CaMKKβ and for designing novel inhibitors targeting CaMKKβ and the related protein kinases.

    In assessing brownfield sites for redevelopment, intrusive investigations are carried out to assess contamination, geology and hydrogeology. Such investigations are expensive, requiring the hire of expensive equipment, which incur standing charges when not in use. In addition, they provide information for discrete sample ';windows'. Non-intrusive methods have the ability to gather information across an entire area. Methods including electrical resistivity/conductivity and ground penetrating radar (GRP), and have been applied to brownfield sites. Their ability in detecting pollution e.g. buried canisters, is often restricted due to unfavourable on-site conditions e.g. GRP is not useful in cases where a layer of clay or reinforced concrete is present. This study is focused on the use, for the first time, of short period seismometers as an alternative, non-intrusive, passive seismic method to detect the presence of objects buried under the ground surface even when on-site conditions are not favourable. We used five low detection threshold seismometers with a flat response within the frequency range 1 - 80 Hz. We conducted experiments both in the lab and in the field. Three series of lab experiments were conducted in sand, under controlled conditions, using ambient noise as the only source of generating seismic waves. Results revealed that there is a distinct difference in the amplitude of the power density spectra of the recorded signals in cases where objects e.g. concrete block, polystyrene block, wood, were present. To validate these results in field scale, we conducted a series of experiments that took place in Heriot-Watt University campus on a field for which we had information for the subsurface from an electromagnetic survey. We used the same monitoring equipment to try and detect the presence of a 6m long PVC pipe buried 0.5m below the ground surface. Results were consistent with those obtained from lab experiments. This supports our initial hypothesis on the

    It is well known that accurate interpretation of the 12-lead electrocardiogram (ECG) requires a high degree of skill. There is also a moderate degree of variability among those who interpret the ECG. While this is the case, there are no best practice guidelines for the actual ECG interpretation process. Hence, this study adopts computerized eye tracking technology to investigate whether eye-gaze can be used to gain a deeper insight into how expert annotators interpret the ECG. Annotators were recruited in San Jose, California at the 2013 International Society of Computerised Electrocardiology (ISCE). Each annotator was recruited to interpret a number of 12-lead ECGs (N=12) while their eye gaze was recorded using a Tobii X60 eye tracker. The device is based on corneal reflection and is non-intrusive. With a sampling rate of 60Hz, eye gaze coordinates were acquired every 16.7ms. Fixations were determined using a predefined computerized classification algorithm, which was then used to generate heat maps of where the annotators looked. The ECGs used in this study form four groups (3=ST elevation myocardial infarction [STEMI], 3=hypertrophy, 3=arrhythmias and 3=exhibiting unique artefacts). There was also an equal distribution of difficulty levels (3=easy to interpret, 3=average and 3=difficult). ECGs were displayed using the 4x3+1 display format and computerized annotations were concealed. Precisely 252 expert ECG interpretations (21 annotators×12 ECGs) were recorded. Average duration for ECG interpretation was 58s (SD=23). Fleiss' generalized kappa coefficient (Pa=0.56) indicated a moderate inter-rater reliability among the annotators. There was a 79% inter-rater agreement for STEMI cases, 71% agreement for arrhythmia cases, 65% for the lead misplacement and dextrocardia cases and only 37% agreement for the hypertrophy cases. In analyzing the total fixation duration, it was found that on average annotators study lead V1 the most (4.29s), followed by leads V2 (3.83s

    Allergic-type diseases are current nowadays, and they are frequently caused by certain metals. We demonstrated that the metal objects can be covered by Teflon protective thin layers using a pulsed laser deposition procedure. An ArF excimer laser beam was focused onto the surface of pressed PTFE powder pellets; the applied fluences were 7.5-7.7 J/cm2. Teflon films were deposited on fourteen-carat gold, silver and titanium plates. The number of ablating pulses was 10000. Post-annealing of the films was carried out in atmospheric air at oven temperatures between 320 and 500 °C. The thickness of the thin layers was around 5 μm. The prepared films were granular without heat treatment or after annealing at a temperature below 340 °C. At 360 °C a crystalline, contiguous, smooth, very compact and pinhole-free thin layer was produced; a melted and re-solidified morphology was observed above 420 °C. The adhesion strength between the Teflon films and the metal substrates was determined. This could exceed 1-4 MPa depending on the treatment temperature. It was proved that the prepared Teflon layers can be suitable for prevention of contact between the human body and allergen metals and so for avoidance of metal allergy.

    This study was designed to analyze the effects of the Ca2+/calmodulin-dependent protein kinase kinase (CaMKK) inhibitor STO-609 (7-oxo-7H-benzimidazo[2,1-a]benz[de]isoquinoline-3-carboxylic acid) toward the aryl hydrocarbon receptor (AhR) pathway because Ca2+/calmodulin-dependent protein kinase (CaMK) Ialpha, known as a downstream CaMKK effector, has been recently shown to contribute to the AhR cascade. STO-609 failed to alter up-regulation of the AhR target CYP1A1 in response to the potent AhR ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in MCF-7 cells. STO-609, used at a 25 muM concentration known to fully inhibit CaMKK activity, was surprisingly found to markedly induce CYP1A1 expression and activity by itself in MCF-7 cells; it similarly up-regulated various other AhR target genes in human macrophages. STO-609-related CYP1A1 induction was prevented by chemical inhibition or small interfering RNA-mediated knockdown expression of AhR. Moreover, STO-609 was demonstrated to physically interact with the ligand-binding domain of AhR, as assessed by TCDD binding competition assay, and to induce AhR translocation to the nucleus. As already reported for AhR agonists, STO-609 triggered the increase of [Ca2+](i) and activation of CaMKIalpha, whose inhibition through the use of the Ca2+ chelator 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid-acetoxymethyl ester or the CaMK inhibitor KN-93 (2-[N-(2-hydroxyethyl)]-N-(4-methoxybenzenesulfonyl)]amino-N-(4-chlorocinnamyl)-N-methylbenzylamine), respectively, prevented STO-609-mediated CYP1A1 activity induction. Taken together, these results demonstrate that the CaMKK inhibitor STO-609 can act as an AhR ligand and, in this way, fully activates the Ca2+/CaMKIalpha/AhR cascade. Such data, therefore, make unlikely any contribution of CaMKK activity to the AhR pathway and, moreover, suggest that caution may be required when using STO-609 as a specific inhibitor of CaMKKs.

    Spermatogonial Stem Cells (SSCs) maintain spermatogenesis throughout the life of the male. Because of the small number of SSCs in adult, enriching and culturing them is a crucial step prior to differentiation or transplantation. Maintenance of SSCs and transplantation or induction of in vitro spermio-genesis may provide a therapeutic strategy to treat male infertility. This study investigated the enrichment and proliferation of SSCs co-cultured with STO cells in the presence or absence of growth factors. Spermatogonial populations were enriched from the testis of 4-6 week-old male mice by MACS according to the expression of a specific marker, Thy-1. Isolated SSCs were cultured in the presence or absence of growth factors (GDNF, GFRα1 and EGF) on STO or gelatin-coated dishes for a week. Subsequently, the authors evaluated the effects of growth factors and STO on SSCs colonization by alkaline phosphates (AP) activity and flow cytometery of α6 and β1 integrins. SSCs co-cultured with STO cells and growth factors developed colonization and AP activity as well as expression of α6 and β1 integrins (P≤0/05). Our present SSC-STO co-culture provides conditions that may allow efficient maintenance and proliferation of SSCs for the treatment of male infertility.

    Full Text Available The purpose of this study is to know the teachers’ opinions in terms of multiple intelligence theory about the objectives and activities in the units of “Earth, Sun and Moon” and the “Electricity in Our Life” in the primary education 5th grade science and technology curriculum. The survey model was used in this study. The population of this study consists of 262 5th grade teachers working in the center of Malatya. The sample consists of 190 5th grade teachers who were selected randomly. Questionnaire was used to collect data that are consisted of 70 items. Teachers are asked to select one dominant intelligence type for 65 objectives and activities. To analyze the data, the background information of teachers like seniority, graduated faculty, whether or not they had in-service education were compared to teachers opinions about which intelligence area is suitable with these objectives and activities and these comparison information was given and commented with frequencies, percentages and cross tabs. Given the results of this study, about evaluating the objectives and activities in these units, taking all activities in the teaching-learning process into consideration, it is discovered that, teachers generally focus on visual, spatial, logical and mathematical intelligence areas and they think in the same way regardless of their seniority, graduated faculty, and whether or not they had in-service education about teaching-learning theories and models. Some advices are given based on the results of this study.

    This paper explores the erosion and problematization of ‘the organization’ as a demarcated entity. Utilizing Foucault's reflections on ‘state-phobia’ as a source of inspiration, I show how an organization-phobia has gained a hold within Organization Theory (OT). By attending to the history...... of this organization-phobia, the paper argues that OT has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming theoretically deconstructed and associated with all kinds of ills. Through this history......, organizations as distinct entities have been rendered so problematic that they have gradually come to be removed from the center of OT. The costs of this have been rather significant. Besides undermining the grounds that gave OT intellectual credibility and legitimacy to begin with, the organization-phobia...

  12. What drives the gender gap in STEM? The SAGA Science, Technology and Innovation Gender Objectives List (STI GOL) as a new approach to linking indicators to STI policies

    There is a large imbalance in the participation of women in Science, Technology, Engineering and Mathematics (STEM) fields across all of Latin American countries despite the fact that the region has one of the highest proportions of female researchers worldwide (44% according to UIS statistics). Female researchers face persisting institutional and cultural barriers, which limit the development of their careers and constrains their access to decision-making positions. In this framework, UNESCO has launched the STEM and Gender Advancement (SAGA) project, which has for objective to address the gender gap in STEM fields in all countries at all levels of education and research as well as to promote women’s participation in science. SAGA is a global UNESCO project with the support of the Swedish Government through the Swedish International Development Cooperation Agency (Sida). One of the outcomes of this project is the SAGA Science, Technology and Innovation Gender Objectives List (STI GOL), which is an innovative tool that aids in the identification of gaps in the policy mix. Additionally, the STI GOL configures the conceptual backbone of the SAGA project, by linking gender equality STI policy instruments with indicators. By using the STI GOL, and identifying the gender gaps, policy-makers will be able to implement evidence-based policies in STEM fields. The SAGA STI GOL is a new and innovative way of contributing to the development of effective gender sensitive policies in STI fields, both in education and in the workplace. Likewise, it enables the categorization of STI policies and instruments, with the objective of identifying gaps in the policy mix and aid in the creation and design of evidence-based public policies to promote gender equality.

    Commercially available interactive video games are commonly used in rehabilitation to aide in physical recovery from a variety of conditions and injuries, including burns. Most video games were not originally designed for rehabilitation purposes and although some games have shown therapeutic potential in burn rehabilitation, the physical demands of more recently released video games, such as Microsoft Xbox Kinect™ (Kinect) and Sony PlayStation 3 Move™ (PS Move), have not been objectively evaluated. Video game technology is constantly evolving and demonstrating different immersive qualities and interactive demands that may or may not have therapeutic potential for patients recovering from burns. This study analyzed the upper extremity motion demands of Kinect and PS Move using three-dimensional motion analysis to determine their applicability in burn rehabilitation. Thirty normal children played each video game while real-time movement of their upper extremities was measured to determine maximal excursion and amount of elevation time. Maximal shoulder flexion, shoulder abduction and elbow flexion range of motion were significantly greater while playing Kinect than the PS Move (p≤0.01). Elevation time of the arms above 120° was also significantly longer with Kinect (pgames show therapeutic potential in burn rehabilitation. Objectively quantifying the physical demands of video games commonly used in rehabilitation aides clinicians in the integration of them into practice and lays the framework for further research on their efficacy.

    The method of graphical genotyping is applied to a panel of tetraploid potato cultivars to visualize haplotype sharing. The method allowed to map genes involved in virus and nematode resistance. The physical coordinates of the amount of linkage drag surrounding these genes are easily interpretable. Graphical genotyping is a visually attractive and easily interpretable method to represent genetic marker data. In this paper, the method is extended from diploids to a panel of tetraploid potato cultivars. Application of filters to select a subset of SNPs allows one to visualize haplotype sharing between individuals that also share a specific locus. The method is illustrated with cultivars resistant to Potato virus Y (PVY), while simultaneously selecting for the absence of the SNPs in susceptible clones. SNP data will then merge into an image which displays the coordinates of a distal genomic region on the northern arm of chromosome 11 where a specific haplotype is introgressed from the wild potato species S. stoloniferum (CPC 2093) carrying a gene (Ny (o,n)sto ) conferring resistance to two PVY strains, PVY(O) and PVY(NTN). Graphical genotyping was also successful in showing the haplotypes on chromosome 12 carrying Ry-f sto , another resistance gene derived from S. stoloniferum conferring broad-spectrum resistance to PVY, as well as chromosome 5 haplotypes from S. vernei, with the Gpa5 locus involved in resistance against Globodera pallida cyst nematodes. The image also shows shortening of linkage drag by meiotic recombination of the introgression segment in more recent breeding material. Identity-by-descent was found to be a requirement for using graphical genotyping, which is proposed as a non-statistical alternative method for gene discovery, as compared with genome-wide association studies. The potential and limitations of the method are discussed.

    Full Text Available This paper describes a methodological proposal for the design, creation and evaluation of Learning Objects (LOs. This study arises from the compilation and analysis of several LO design methodologies currently used in Ibero-America. This proposal, which has been named DICREVOA, defines five different phases: analysis, design (instructional and multimedia, implementation (LO and metadata, evaluation (from the perspective of both the producer and the consumer of the LO, and publishing. The methodology focuses not only on the teaching inexperienced, but also on those having a basic understanding of the technological and educational aspects related to LO design; therefore, the study emphasizes LO design activities centered around the Kolb cycle and the use of the ExeLearning tool in order to implement the LO core. Additionally, DICREVOA was used in a case study, which demonstrates how it provides a feasible mechanism for LO design and implementation withindifferent contexts. Finally, DICREVOA, the case study to which it was applied, and the results obtained are presented.

    Full Text Available The objects of the study are as follows: rudd and goldfish, samples of food minced made of them without washing, after single and double washings. To study the organoleptic and physico-chemical parameters the conventional methods of the fishing industry have been used. At the LLC "Astrakhan fisheries" two experimental batches of minced rudd and goldfish with double washing by water using a food additive "Omfresh plus" have been made in the amount of 1.0 % by weight of the meat. The yield of washed minced food from rudd is 41.4 %, from silver carp – 41.0 %. Some decrease in water content, water-holding capacity and formalin-titratable nitrogen in minced fish after each washing step has been established. Studying the organoleptic characteristics has shown that the frozen minced briquettes are cuboids, have clean surface with the presence of minor irregularities, colour – light gray, dense texture. On physical and chemical parameters the food washed mince correspond to GOST R 55505–2013 "Frozen food fish forcemeat. Specifications". Water content is 79–82 %, sodium chloride – 0,17–0,35 %, and water-holding capacity – at over 50 %. The proven technology of manufacturing washed minced from goldfish and rudd can be put into production for the purpose of deep processing of unprofitable species of the Volga-Caspian Basin and getting washed minced food and culinary products based on it.

    Science.gov (United States)

    1997-01-01

    Technology Access for Product Innovation (TAP-IN), the largest technology deployment project funded by TRP, was competitively selected through a national solicitation for proposals. TAP-IN was created to help companies access and apply defense technologies and help defense-dependent companies enter new commercial markets. Defense technologies included technologies developed by DoD, DOE, NASA, and their contractors. TAP-IN was structured to provide region-based technology access services that were able to draw on technology resources nationwide. TAP-IN provided expert assistance in all stages of the commercialization process from concept through prototype design to capital sourcing and marketing strategy. TAP-IN helped companies locate new technology, identify business partners, secure financing, develop ideas for new products, identify new markets, license technology, solve technical problems, and develop company-specific applications of federal technology. TAP-IN leveraged NASA's existing commercial technology network to create an integrated national network of organizations that assisted companies in every state. In addition to NASA's six regional technology transfer centers (RTTCs), TAP-IN included business and technology development organizations in every state, the Industrial Designers Society of America, and the Federal Laboratory Consortium (FLC).

    This dissertation identifies the main factors which represent the conditions for the potential commercialization of patents aiming at the implementation of a system for technology public offering at CNEN as a strategy for creating licensing opportunities to the industrial sector. The method applied refers to an exploratory case study of a patented technology selected from a sample of CNEN's patent portfolio in the biopharmaceutical sector. The case study comprehends a field research of interviews conducted with two specialists in technology and innovation management, one researcher from CNEN and a biopharmaceutical company. The results show that among the nineteen main factors - related to technology, market, business and Science and Technology Organization (STO) - the market dynamics, the potential applications of the technology and an abstract of its main benefits compared to existing technologies are the major relevant information for each technology to be included in the public offering system. Other results indicate that the evaluation of such factors may be conducted by competent professionals to bring less uncertainty and risk to the early-stage of the innovation process, as well as enhance the potential interest of a company in the technology. On the other hand, the latter requires innovation capabilities to move the technology forward – additional R&D, scale-up, manufacturing and marketing - whilst the STO needs a entrepreneurial culture that mitigates its obstacles, creates more positive solutions for its routines and processes and gives sustainability to its Technology Transfer Office (TTO) through valuing its personnel in the long term. Finally, emphasis on technological partnerships with companies can be a motivating feature for directing the STO's patent strategy to the creation of proprietary technological platforms that reflect problems experienced by the commercial environment, as well as the development of this strategic patent

  8. Information technology and innovative drainage management practices for selenium load reduction from irrigated agriculture to provide stakeholder assurances and meet contaminant mass loading policy objectives

    Energy Technology Data Exchange (ETDEWEB)

    Quinn, N.W.T.

    2009-10-15

    Many perceive the implementation of environmental regulatory policy, especially concerning non-point source pollution from irrigated agriculture, as being less efficient in the United States than in many other countries. This is partly a result of the stakeholder involvement process but is also a reflection of the inability to make effective use of Environmental Decision Support Systems (EDSS) to facilitate technical information exchange with stakeholders and to provide a forum for innovative ideas for controlling non-point source pollutant loading. This paper describes one of the success stories where a standardized Environmental Protection Agency (EPA) methodology was modified to better suit regulation of a trace element in agricultural subsurface drainage and information technology was developed to help guide stakeholders, provide assurances to the public and encourage innovation while improving compliance with State water quality objectives. The geographic focus of the paper is the western San Joaquin Valley where, in 1985, evapoconcentration of selenium in agricultural subsurface drainage water, diverted into large ponds within a federal wildlife refuge, caused teratogenecity in waterfowl embryos and in other sensitive wildlife species. The fallout from this environmental disaster was a concerted attempt by State and Federal water agencies to regulate non-point source loads of the trace element selenium. The complexity of selenium hydrogeochemistry, the difficulty and expense of selenium concentration monitoring and political discord between agricultural and environmental interests created challenges to the regulation process. Innovative policy and institutional constructs, supported by environmental monitoring and the web-based data management and dissemination systems, provided essential decision support, created opportunities for adaptive management and ultimately contributed to project success. The paper provides a retrospective on the contentious planning

  9. Object crowding.

    Crowding occurs when stimuli in the peripheral fields become harder to identify when flanked by other items. This phenomenon has been demonstrated extensively with simple patterns (e.g., Gabors and letters). Here, we characterize crowding for everyday objects. We presented three-item arrays of objects and letters, arranged radially and tangentially in the lower visual field. Observers identified the central target, and we measured contrast energy thresholds as a function of target-to-flanker spacing. Object crowding was similar to letter crowding in spatial extent but was much weaker. The average elevation in threshold contrast energy was in the order of 1 log unit for objects as compared to 2 log units for letters and silhouette objects. Furthermore, we examined whether the exterior and interior features of an object are differentially affected by crowding. We used a circular aperture to present or exclude the object interior. Critical spacings for these aperture and "donut" objects were similar to those of intact objects. Taken together, these findings suggest that crowding between letters and objects are essentially due to the same mechanism, which affects equally the interior and exterior features of an object. However, for objects defined with varying shades of gray, it is much easier to overcome crowding by increasing contrast.

    During the past decade the reduction in size of functional architectures has been a dominating trend in many fields of science and technology. The search for electronic materials that can be cheaply solution-processed into nanopowders, while simultaneously providing quality device characteristics, represents a major challenge for material scientists. Solvothermal process is used in order to obtain fine nanoparticles of BaTiO{sub 3} and SrTiO{sub 3} at low temperatures by using an inorganic, ionic precursor. Rietveld refinement proves the presence of a mixture of 65% tetragonal and 35% cubic nanoparticles in the barium titanate powder with an average size of 73 nm and 67 nm, respectively. FTIR shows that an acid treatment allows the elimination of carbonate impurities.

    2014-01-01

    Measurements of CP violation in $B^0_d\\to J/\\psi K_{\\rm S}^0$ and $B^0_s\\to J/\\psi \\phi$ decays play key roles in testing the quark-flavour sector of the Standard Model. The theoretical interpretation of the corresponding observables is limited by uncertainties from doubly Cabibbo-suppressed penguin topologies. With continuously increasing experimental precision, it is mandatory to get a handle on these contributions, which cannot be calculated reliably in QCD. In the case of the measurement of $\\sin2\\beta$ from $B^0_d\\to J/\\psi K_{\\rm S}^0$, the $U$-spin-related decay $B^0_s\\to J/\\psi K_{\\rm S}^0$ offers a tool to control the penguin effects. As the required measurements are not yet available, we use data for decays with similar dynamics and the $SU(3)$ flavour symmetry to constrain the size of the expected penguin corrections. We predict the CP asymmetries of $B^0_s\\to J/\\psi K_{\\rm S}^0$ and present a scenario to fully exploit the physics potential of this decay, emphasising also the determination of hadro...

  1. Arabidopsis STO/BBX24 negatively regulates UV-B signaling by interacting with COP1 and repressing HY5 transcriptional activity.

    2012-06-01

    UV-B (280-315 nm) is an integral part of solar radiation and can act either as a stress inducer or as a developmental signal. In recent years, increasing attention has been paid to the low-fluence UV-B-induced photomorphogenic response and several key players in this response have been identified, which include UVR8 (a UV-B-specific photoreceptor), COP1 (a WD40-repeat-containing RING finger protein), HY5 (a basic zipper transcription factor), and RUP1/2 (two UVR8-interacting proteins). Here we report that Arabidopsis SALT TOLERANCE (STO/BBX24), a known regulator for light signaling in plants, defines a new signaling component in UV-B-mediated photomorphogenesis. The bbx24 mutant is hypersensitive to UV-B radiation and becomes extremely dwarfed under UV-B treatment. By contrast, BBX24 overexpression transgenic lines respond much more weakly to UV-B than the bbx24 and wild-type plants. BBX24 expression is UV-B-inducible and its accumulation under UV-B requires COP1. Co-immunoprecipitation experiments indicate that BBX24 interacts with COP1 in planta upon UV-B illumination. Moreover, BBX24 interacts with HY5 and acts antagonistically with HY5 in UV-B-induced inhibition of hypocotyl elongation. Furthermore, BBX24 attenuates UV-B-induced HY5 accumulation and suppresses its transcription-activation activity. Taken together, our results reveal a previously uncharacterized function of the light-regulated BBX24 in UV-B responses and demonstrate that BBX24 functions as a negative regulator of photomorphogenic UV-B responses by interacting with both COP1 and HY5. The UV-B-inducible expression pattern and its suppression of HY5 activity suggest that BBX24 could be a new component of the feedback regulatory module of UV-B signaling in plants.

  2. Culture of mouse amniotic fluid-derived cells on irradiated STO feeders results in the generation of primitive endoderm cell lines capable of self-renewal in vitro.

    The cells present in amniotic fluid (AF) are currently used for prenatal diagnosis of fetal anomalies but are also a potential source of cells for cell therapy. To better characterize putative progenitor cell populations present in AF, we used culture conditions that support self-renewal to determine if these promoted the generation of stable cell lines from AF-derived cells (AFC). Cells isolated from E11.5 mouse were cultured on irradiated STO fibroblast feeder layers in human embryonic germ cell derivation conditions. The cultures grew multicellular epithelial colonies that could be repropagated from single cells. Reverse transcription semiquantitative polymerase chain reaction of established cell lines revealed that they belonged to the extraembryonic endoderm (ExEn) expressing high levels of Gata6, Gata4, Sox17, Foxa2 and Sox7 mRNA. Hierarchical clustering based on the whole transcriptome expression profile of the AFC lines (AFCL) shows significant correlation between transcription profiles of AFCL and blastocyst-derived XEN, an ExEn cell line. In vitro differentiation of AFCL results in the generation of cells expressing albumin and α-fetoprotein (AFP), while intramuscular injection of AFCL into immunodeficient mice produced AFP-positive tumors with primitive endodermal appearance. Hence, E11.5 mouse AF contains cells that efficiently produce XEN lines. These AF-derived XEN lines do not spontaneously differentiate into embryonic-type cells but are phenotypically stable and have the capacity for extensive expansion. The lack of requirement for reprogramming factors to turn AF-derived progenitor cells into stable cell lines capable of massive expansion together with the known ability of ExEn to contribute to embryonic tissue suggests that this cell type may be a candidate for banking for cell therapies. © 2013 S.

    Andersen, Bjørn Schiermer

    2009-01-01

    This article attempts to create a framework for understanding modern fashion phenomena on the basis of Durkheim's sociology of religion. It focuses on Durkheim's conception of the relation between the cult and the sacred object, on his notion of 'exteriorisation', and on his theory of the social...... symbol in an attempt to describe the peculiar attraction of the fashion object and its social constitution. However, Durkheim's notions of cult and ritual must undergo profound changes if they are to be used in an analysis of fashion. The article tries to expand the Durkheimian cult, radically enlarging...... it without totally dispersing it; depicting it as held together exclusively by the sheer 'force' of the sacred object. Firstly, the article introduces the themes and problems surrounding Durkheim's conception of the sacred. Next, it briefly sketches an outline of fashion phenomena in Durkheimian categories...

    The object of this paper is to study the impervious surface extraction method using remote sensing imagery and monitor the spatiotemporal changing patterns of mega cities. Megacity Bombay was selected as the interesting area. Firstly, the pixel-based and object-oriented support vector machine (SVM) classification methods were used to acquire the land use/land cover (LULC) products of Bombay in 2010. Consequently, the overall accuracy (OA) and overall Kappa (OK) of the pixel-based method were 94.97% and 0.96 with a running time of 78 minutes, the OA and OK of the object-oriented method were 93.72% and 0.94 with a running time of only 17s. Additionally, OA and OK of the object-oriented method after a post-classification were improved up to 95.8% and 0.94. Then, the dynamic impervious surfaces of Bombay in the period 1973-2015 were extracted and the urbanization pattern of Bombay was analysed. Results told that both the two SVM classification methods could accomplish the impervious surface extraction, but the object-oriented method should be a better choice. Urbanization of Bombay experienced a fast extending during the past 42 years, implying a dramatically urban sprawl of mega cities in the developing countries along the One Belt and One Road (OBOR).

  5. Objective becoming

    2015-01-01

    Bradford Skow presents an original defense of the 'block universe' theory of time, often said to be a theory according to which time does not pass. Along the way, he provides in-depth discussions of alternative theories of time, including those in which there is 'robust passage' of time or 'objective becoming': presentism, the moving spotlight theory of time, the growing block theory of time, and the 'branching time' theory of time. Skow explains why the moving spotlight theory is the best of these arguments, and rebuts several popular arguments against the thesis that time passes. He surveys the problems that the special theory of relativity has been thought to raise for objective becoming, and suggests ways in which fans of objective becoming may reconcile their view with relativistic physics. The last third of the book aims to clarify and evaluate the argument that we should believe that time passes because, somehow, the passage of time is given to us in experience. He isolates three separate arguments thi...

    Barnett and Coulson's zeta-function method (M. P. Barnett and C. A. Coulson, Philos. Trans. R. Soc., Lond. A 1951, 243, 221) is one of the main sources of algorithms for the solution of multicenter integrals with Slater-type orbitals. This method is extended here from single functions to two-center charge distributions, which are expanded at a third center in terms of spherical harmonics times analytical radial factors. For s-s distributions, the radial factors are given by a series of factors corresponding to the translation of s-type orbitals. For distributions with higher quantum numbers, they are obtained from those of the s-s distributions by recurrence. After analyzing the convergence of the series, a computational algorithm is proposed and its practical efficiency is tested in three-center (AB/CC) repulsion integrals. In cases of large basis sets, the procedure yields about 12 correct significant figures with a computational cost of a few microseconds per integral.

    UV-B (280-315 nm) is an integral part of solar radiation and can act either as a stress inducer or as a developmental signal.In recent years,increasing attention has been paid to the Iow-fluence UV-B-induced photomorphogenic response and several key players in this response have been identified,which include UVR8 (a UV-B-specific photoreceptor),COPI (a WD40-repeat-containing RING finger protein),HY5 (a basic zipper transcription factor),and RUP1/2 (two UVR8-interacting proteins).Here we report that Arabidopsis SALT TOLERANCE (STO/BBX24),a known regulator for light signaling in plants,defines a new signaling component in UV-B-mediated photomorphogenesis.The bbx24 mutant is hypersensitive to UV-B radiation and becomes extremely dwarfed under UV-B treatment.By contrast,BBX24 overexpression transgenic lines respond much more weakly to UV-B than the bbx24 and wild-type plants.BBX24 expression is UV-B-inducible and its accumulation under UV-B requires COP1.Co-immunoprecipitation experiments indicate that BBX24 interacts with COP1 in planta upon UV-B illumination.Moreover,BBX24 interacts with HY5 and acts antagonistically with HY5 in UV-B-induced inhibition of hypocotyl elongation.Furthermore,BBX24 attenuates UV-B-induced HY5 accumulation and suppresses its transcription-activation activity.Taken together,our results reveal a previously uncharacterized function of the light-regulated BBX24 in UV-B responses and demonstrate that BBX24 functions as a negative regulator of photomorphogenic UV-B responses by interacting with both COP1 and HY5.The UV-B-inducible expression pattern and its suppression of HY5 activity suggest that BBX24 could be a new component of the feedback regulatory module of UV-B signaling in plants.

    With the seriousness of the climate change threat, the European Union has invited its member states to adopt the goal of dividing by a factor 4 their greenhouse gas emissions before 2050. France has answered this invitation and requested the De Boissieu Commission to make an inventory of the means allowing to reach this goal. A first debate took place at Grenoble on November 16, 2006 about the technological and industrial consequences of such a perspective and about the necessary R and D trends to be implemented (socio-economic impacts, changes in the sectors of transportation, dwellings, space heating, lighting and air-conditioning, role of nuclear and renewable energy sources). The results of these debates are summarized in this newsletter: what is Factor 4; what are the technological, economical and social implications; the achievable changes in the transportation sector; HOMES project: optimized dwellings and buildings for energy mastery and services; role of nuclear energy in the reduction of the fossil fuels share; rise in power of renewable energy sources.

  11. Objective thermomechanics

    Fülöp, Tamás

    2015-01-01

    An irreversible thermodynamical theory of solids is presented where the kinematic quantities are defined in an automatically objective way. Namely, auxiliary elements like reference frame, reference time and reference configuration are avoided by formulating the motion of the continuum on spacetime directly, utilizing the Weyl-Matolcsi description of spacetime. This restricts the range of definable kinematic quantities heavily. Solids are distinguished from fluids by possessing not only an instantaneous metric tensor but a relaxed metric, too, that represents the natural geometric structure of the solid. The comparison of the instantaneous metric to the relaxed one is the basis of the definition of the elastic state variable, the elastic deformedness tensor. Thermal expansion is conceived as the temperature dependence of the relaxed metric. As opposed to this reversible type of change, plasticity means an irreversible change in the relaxed metric, and is describable via a plastic change rate tensor. The relat...

    A case-based program called ATLes (Adaptive Teaching and Learning Environments) was designed for use in a systemic pathology course and implemented over a four-year period. Second-year veterinary students working in small collaborative learning groups used the program prior to their weekly pathology laboratory. The goals of ATLes were to better address specific learning objectives in the course (notably the appreciation of pathophysiology), to solve previously identified problems associated with information overload and information sorting that commonly occur as part of discovery-based processes, and to enhance classroom discussion. The program was also designed to model and allow students to practice the problem-oriented approach to clinical cases, thereby enabling them to study pathology in a relevant clinical context. Features included opportunities for students to obtain additional information on the case by requesting specific laboratory tests and/or diagnostic procedures. However, students were also required to justify their diagnostic plans and to provide mechanistic analyses. The use of ATLes met most of these objectives. Student acceptance was high, and students favorably reviewed the online ''Content Links'' that made useful information more readily accessible and level appropriate. Students came to the lab better prepared to engage in an in-depth and high-quality discussion and were better able to connect clinical problems to underlying changes in tissue (lesions). However, many students indicated that the required time on task prior to lab might have been excessive relative to what they thought they learned. The classroom discussion, although improved, was not elevated to the expected level-most likely reflecting other missing elements of the learning environment, including the existing student culture and the students' current discussion skills. This article briefly discusses the lessons learned from ATLes and how similar case-based exercises might be

    2016-09-01

    Full Text Available The paper presents the results of justifying the use of thorny skate in the technology of minced meat canned products of special purpose. The key criterion determined the specialized purpose of canned food is the high content of physiologically functional food ingredient of chondroitin sulfate in the cartilage of thorny skate wings. The high content of chondroitin sulfate in raw materials ensures that the content of the physiologically functional ingredient in the finished canned food will be at the level from 220 to 250 mg per 100 g of product. The method of IR blanching is presented for removing urea from the thorny skate muscle tissue. To confirm the efficiency of the developed method of urea removal, it has been proposed to use a modified photocolorimetric method for determination of mass fractions of urea in feed flour according to the governmental standard GOST R 50032–92 "Feed flour made of fish, marine mammals, crustaceans and invertebrates. Methods of determining the mass fraction of urea and calculation of the crude protein with a given mass fraction of carbamide". With the help of this technique, the efficiency of urea removal from the thorny skate tissue by the proposed method has been determined. The residual urea content in the meat of thorny skate after IR blanching is 0.76 %, which is two times lesser than border value of sensitivity of the person (approximated as 1.2 %. The paper presents the materials of experimental substantiation of optimum formulation of new canned meat based on the method of fuzzy modeling. The ratio of the main components of the meatballs recipe (thorny skate and Atlantic cod close to the optimum is 48 % by weight of meat for each component separately.

    An assessment study is presented about energy decomposition analysis (EDA) in combination with DFT including revised dispersion correction (DFT-D3) with Slater-type orbital (STO) basis set. There has been little knowledge about the performance of the EDA + DFT-D3 concerning STOs. In this assessment such an approach was applied to calculate noncovalent interaction energies and their corresponding components. Complexes in S22 set were used to evaluate the performance of EDA in conjunction with four representative types of GGA-functionals of DFT-D3 (BP86-D3, BLYP-D3, PBE-D3 and SSB-D3) with three STO basis sets ranging in complexity from DZP, TZ2P to QZ4P. The results showed that the approach of EDA + BLYP-D3/TZ2P has a better performance not only in terms of calculating noncovalent interaction energy quantitatively but also in analyzing corresponding energy components qualitatively. This approach (EDA + BLYP-D3/TZ2P) was thus applied further to two representative large-system complexes including porphine dimers and fullerene aggregates to gain a better insight into binding characteristics.

    The 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program was included in the environmental licensing process of the Rio de Janeiro-Minas Gerais gas pipeline ('GASBEL II'), as requested by the Palmares Cultural Foundation (Fundacao Cultural Palmares), which stipulates the elaboration and implementation of this program as a condition for obtaining the installation license. To develop the program and submit it to this institution, we used methodological procedures in the form of an anthropological social research, such as: interviews with the community's older or most active residents, and a preliminary recognition of the territory and the local culture; all in order to learn more about the community's history and current needs and to identify the remaining 'quilombolas' still living in the community. Analyzing the information raised the need for guided actions designed to rescue the community's cultural memory as an ethnic group and to contribute to its process of affirmation as a Traditional Rural 'Quilombola' Community. This led to the creation of the proposed 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program, currently being developed for the Quilombola Community located in Ressaquinha, in the State of Minas Gerais. (author)

    为了快速监测湖北省土地覆被变化,以HJ-CCD、TM以及ETM影像为数据源,探索出了集成面向对象技术与“3S”技术的中尺度土地覆被变化遥感流程和方法。该方法首先基于HJ-CCD影像和面向对象技术进行2010年湖北省土地覆被信息的提取,并用野外采样点对结果进行验证。在保证高精度的情况下利用向量相似性函数对湖北省2000-2005年以及2005-2010年进行变化检测,从而获得2个变化时期影像的变化区域,然后利用面向对象技术中的最邻近分类器对变化区进行自动化分类。最后分别将2期的变化结果与未变化结果融合后获得湖北省2000年、2005年和2010年的土地覆被图,在GIS中处理后建成县、市、省3级行政级别的湖北省土地覆被变化本底数据库。试验表明分类结果的总体精度为93.24%,Kappa系数为0.914;2000-2005年与2005-2010年变化检测的总体精度分别为90.88%和90.75%。同时研究发现景观破碎的地区应用面向对象技术有一定的局限性。%The rapid development of RS、GIS, and GPS technology provide a fast and effective means for the dynamic monitoring of land-cover change detection. Many scholars have researched constructing a land-cover change dynamic database with various remote sensing imageries. In conclusion, the main sources to date are abroad remote sensing imagery, while the Chinese HJ-CCD imageries rarely are used in cover-wetlands information extraction. More important, the traditional pixel-based methods which have been universally applied in land-cover/land-use information extraction for many years cannot meet the application need of land-cover/land-use information extraction because it only uses the spectral features of imagery, ignoring other information that the remote sensing imagery carries. The object-oriented technology not only uses spectral features, but also makes full use of texture features、spatial features

    Redundant information can be integrated effectively and visual effect is enhanced through the multi-sensor image fusion techniques. Due to the prominent target and lower background contrast for infrared images, while high resolution but insensitive to hot and concealed targets for visible images,an effective image fusion method,which can highlight the two images without reducing the image resolution, is presented in this paper. Firstly, targets are extracted from the infrared image by Renyi entropy,and the visible image is enhanced adaptively through non-subsample Contourlet transform (NSCT). Then the enhanced visible image is fused with the target infrared image. Finally, two different sets of infrared and visible images are used for image fusion test by different methods. By contrst, the fused image has significantly improve brightness and higher contrast than other images,and has better visual effect. In order to objectively evaluate the proposed method,many evaluations, such as information entropy (IE) , standard deviation (STD), spatial frequency (SF), mutual information (MI) and running time, are adopted to make comparision with other fusion methods. The results show that the IE,STD,SF and MI values of the proposed method, obtained are significantly higher than those of the other methods. The proposed method has longer running time than the Laplace, wavelet transform and Renyi entropy methods, but shorter running time than other methods. So the proposed method is an effective image fusion one.%针对红外图像目标突出、背景对比度差、可见光图像分辨率高以及对热目标不敏感且隐蔽目标无法发现等问题,本文提出了一种能够突出两种图像的优势信息且不降低图像分辨率的图像融合方法.首先采用Renyi熵提取红外目标,并通过非下采样Contourlet变换(NSCT)对可见光图像进行自适应增强;然后将图像增强后的可见光图像与目标图像进行融合,得到融合图像.通过

    Full Text Available Le De clementia se présente comme un traité à fonction parénétique destiné à guider Néron sur la voie du bon gouvernement en le convaincant de pratiquer la clémence, élevée au rang de vertu cardinale. Mais à un moment où à Rome le stoïcisme apparaît comme lié par la figure de Caton aux valeurs républicaines, l’œuvre participe aussi d’un débat interne au Portique. Sénèque se réclame quant à lui du stoïcisme orthodoxe à la fois pour justifier son acceptation de la monarchie absolue et la place éminente qu’il accorde à la clémence, essentielle dans ce type de régime. Sur le plan des institutions, le dossier de Sénèque paraît solide ; en ce qui concerne la clémence on peut considérer qu’il cherche à faire évoluer la doctrine, même s’il raisonne toujours dans les cadres stoïciens. L’Histoire suffit à prouver que Sénèque n’a pas convaincu, mais il n’en reste pas moins que le De clementia est l’œuvre d’un stoïcien authentique.De clementia is a treaty of exhortation for guiding Nero on the road to good government by convincing him to practice clemency, in so far as it is considered as a cardinal virtue. But at a time when Stoicism in Rome seems bound by the figure of Cato to Republican values, this work also involves an internal debate in Stoicism. Seneca claims an orthodox Stoicism both to justify its acceptance of absolute monarchy and the prominent place that he grants to clemency, which is essential in this kind of political system. On the institutional level, Seneca seems to have solid argumentation ; as far as clemency is concerned, he can be regarded as seeking to change the doctrine, even if he continues to invoke frames of Stoicism. Historical events are enough to prove that Seneca did not convince, but it remains the case that De clementia is the work of a true Stoic.Il De clementia si presenta come un trattato dalla funzione parenetica destinato a guidare Nerone sulla via del

    The prompt and non-prompt production cross-sections for $\\psi(2S)$ mesons are measured using 2.1 fb$^{-1}$ of $pp$ collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The measurement exploits the $\\psi(2S)\\to J/\\psi(\\to\\mu^+\\mu^-)\\pi^+\\pi^-$ decay mode, and probes $\\psi(2S)$ mesons with transverse momenta in the range $10\\leq p_T<100$ GeV and rapidity $|y|<2.0$. The results are compared to other measurements of $\\psi(2S)$ production at the LHC and to various theoretical models for prompt and non-prompt quarkonium production.

    Pulsed Laser Deposition is a state-of-the-art technique that allows for the fine tunability of the deposition rate, highly uniform and epitaxial sample growth, the ability to introduce partial pressures of gases into the experimental chamber for growth of complex materials without interfering with the energy source (laser). An auxiliary in situ technique for growth monitoring, Reflection High-Energy Electron Diffraction, is a powerful characterization tool for predictability of the surface physical structure both, qualitatively and quantitatively. RHEED patterns during and post deposition of Ag thin films on MgO, Al2O3, Si and STO substrtates are presented and their interpretations are compared with surface imaging techniques (SEM, STM) to evidence the usefulness of the technique.

    Health-related quality of life (HRQL) is a fundamental outcome in surgical oncology and culturally valid tools are essential for this purpose. Our aim was to validate the Mexican-Spanish versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire QLQ-C30 and the QLQ-STO22 disease-specific questionnaire module in Mexican patients with gastric cancer (GC). The translation procedure followed EORTC guidelines. Both instruments were completed by patients with GC and analyses were performed within three clinically distinct groups: (1) patients undergoing palliative treatment, (2) patients undergoing treatment with curative intent, and (3) GC survivors. Tests for reliability and validity were performed. One hundred and fifty patients (mean age 54.2 years) completed both questionnaires. Sixty-seven, 55, and 28 patients were allocated to groups 1, 2, and 3, respectively. Compliance rates were high, and questionnaires were well-accepted. Survivors of treatment for GC reported better functional HRQL scores and lower symptom scores than patients in group 2 who were currently undergoing treatment. Patients selected for potentially curative treatment had better HRQL than group 1 (palliative treatments). Scales in the QLQ-C30 and QLQ-STO22 distinguished between other clinically distinct groups of patients. Cronbach's alpha coefficients of 14 scales of both questionnaires were >0.7. Multitrait scaling analysis demonstrated good convergent and discriminant validity. Test-retest scores were consistent. We conclude that the Mexican-Spanish versions of EORTC QLQ-C30 and QLQ-C22 questionnaires are reliable and valid for HRQL measurement in patients with GC and are therefore recommended for use in clinical trials of Mexican community.

    This article attempts to rehabilitate the concept of fetishism and to contribute to the debate on the social role of objects as well as to fashion theory. Extrapolating from Michel Serres’ theory of the quasi-objects, I distinguish two phenomenologies possessing almost opposite characteristics....... These two phenomenologies are, so I argue, essential to quasi-object theory, yet largely ignored by Serres’ sociological interpreters. They correspond with the two different theories of fetishism found in Marx and Durkheim, respectively. In the second half of the article, I introduce the fashion object...... as a unique opportunity for studying the interchange between these two forms of fetishism and their respective phenomenologies. Finally, returning to Serres, I briefly consider the theoretical consequences of introducing the fashion object as a quasi-object....

  3. Airborne geophysical survey of the catastrophic landslide at Stože, Log pod Mangrtom, as a test of an innovative approach for landslide mapping in steep alpine terrains

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Airborne geophysics is a promising method for investigating landslides. Here we present a case study of multisensor airborne geophysical survey at the catastrophic landslide Stože near Log pod Mangrtom in Slovenia, which was conducted in the framework of the European FP7th Project "SafeLand". Based on the survey itself and achieved results, we discuss applicability, limits, and benefits and costs of the method for investigating landslides in steep alpine terrains. Despite of several operational constraints, the airborne electromagnetic survey of the area well presented the lithological pattern and water saturation. The high resistivity regions mostly indicated drained slope scree and landslide mass, drained and loosened material of the moraine deposit in the tension zone of the landslide with present cracks and cavities. The minima of the resistivity pattern were attributed to the outcrop of marls rich in clay, to water-saturated moraine deposit above impermeable marls in the tension zone, and to water-saturated porous alluvial gravel and landslide scree along the Koritnica River. The magnetic survey proved to be inapplicable for such a small and rough area. The Potassium and Thorium maps, on the other hand, both well identified the regions of tension inside the landslide zone, outcrops of marls and dolomite, clay-rich colluvium, weathered zones along a regional tectonic fault, and alluvial deposits and deposits of debris flows, and the minima of the 137Cs clearly revealed the zones of material removal due to recent mass movements.

A clear prove of OO application in all situations is the development of a wide range of industrial applications. OO technology allows drawing of relation between the geometry, topology and dimensions of data on a class hierarchy; thus, the observation of the amount of data gained by research in many scientific domains is facilitated through class libraries both for graphic primitives and for events examination. In conformity to all waiting, OO asserts in every distributive system, there are very important the applications for making open systems customer-server and dis-tributed applications in Java. Finally OO application in robot's programming and modeling needn't be omitted. However, far to be panacea, OO has also shades which will be researched so on.

    It has become acceptable among historians of medicine to profess a predilection for the historiography of medical ideas. But it is justified all the same to ask whether the logical connection really caused the origin, the change, or the disappearance of the medical objects. The interaction of ideas and medical objects assure as much objectivity as possible. In consequence, the contents of the museums, medical objects, is an aspect rather that a branch of the history of medicine.

    One thing scientists study is how objects move. A famous scientist named Sir Isaac Newton (1642-1727) spent a lot of time observing objects in motion and came up with three laws that describe how things move. This explanation only deals with the first of his three laws of motion. Newton's First Law of Motion says that moving objects will continue…

    Full Text Available Resolution of the problem of mass nouns depends on an expansion of our semantic/ontological taxonomy. Semantically, mass nouns are neither singular nor plural; they apply to neither just one object, nor to many objects, at a time. But their deepest kinship links them to the plural. A plural phrase — 'the cats in Kingston' — does not denote a single plural thing, but merely many distinct things. Just so, 'the water in the lake' does not denote a single aggregate — it is not ONE, but rather MUCH. The world is not the totality of singular objects, plural objects, and mass objects; for there are no plural or mass objects. It is the totality of single objects and (just stuff.

  8. Extending Object-Oriented Languages by Declarative Specifications of Complex Objects using Answer-Set Programming

    CERN Document Server

    Oetsch, Johannes; Tompits, Hans

    2011-01-01

    Many applications require complexly structured data objects. Developing new or adapting existing algorithmic solutions for creating such objects can be a non-trivial and costly task if the considered objects are subject to different application-specific constraints. Often, however, it is comparatively easy to declaratively describe the required objects. In this paper, we propose to use answer-set programming (ASP)---a well-established declarative programming paradigm from the area of artificial intelligence---for instantiating objects in standard object-oriented programming languages. In particular, we extend Java with declarative specifications from which the required objects can be automatically generated using available ASP solver technology.

  11. Pathways of geomorphic evolution of sandstone escarpments in the Góry Stołowe tableland (SW Poland) - Insights from LiDAR-based high-resolution DEM

    Science.gov (United States)

    Migoń, Piotr; Kasprzak, Marek

    2016-05-01

    The tableland of the Stołowe Mountains (SW Poland), with its prominent mesas and sandstone-capped escarpments, belongs to the most spectacular geomorphic landscapes of Central Europe. While the gross morphological features of the area have long been recognized, the evolutionary pathways of densely forested and poorly accessible escarpment slopes remained poorly understood. In this paper we use LiDAR data to shed a new light on landform inventories within the escarpments, their spatial patterns and, using process-from-form reasoning, on the longer-term evolution of the escarpments. Four sites, two on each major escarpment, have been subject to detailed analysis which involved examination of shaded relief, slope, plan and profile curvature and topographic wetness index. In each case, the 1 × 1 m model was used, while for the most complex site at Mt. Szczeliniec Wielki the results were compared with the 5 × 5 m model to check the impact of model resolution on geomorphic interpretation. Despite some loss of information involved in model re-interpolation to the coarser scale, the main features of escarpment morphology could still be recognized. On the other hand, automatic landform classification based on the calculation of Topographic Position Index from the 10 × 10 m model and performed for the entire tableland failed to reveal differences between various sections of the escarpments, detectable on finer models. The analysis of spatial patterns of minor landforms within the escarpments, identified on LiDAR-derived models shows that no single pathway of escarpment evolution exists. Both the upper slopes (in sandstone caprock) and the mid-slopes (in weaker rocks) show signs of instability and these are not necessarily coupled. Large-scale caprock failures do occur but seem rare and localized. Sandstone free faces are rather subject to continuous slow retreat by detachment of individual joint-bound blocks. Another zone of instability occurs well below the caprock and

    Sediments can pose a threat to humans not only when these deposits are polluted but also due to their large quantities. This physical aspect of sediments as a risk will be shown on a case study of a sediment-related disaster that occurred in the mountainous part of Slovenia, Central Europe in 2000. In November 2000, after a long wet period a large debris landslide had been triggered on the Stože slope and stopped in the channel of the Mangart creek. Such an event took the majority of local inhabitants and emergency staff by surprise. Nevertheless, they had just organized the first mitigation measures when, after 35 hours, they were surprised by an even larger debrisflowinitiated as the second phase of the same mass movement event. Within a few minutes, the wet debris flow had devastated the alpine valley of the Koritnica River and killed 7 people in the village of Log pod Mangartom. This paper deals with crisis management and first mitigation measures under this very tense situation of searching for dead bodies. The uncertainty about possible new debris flows drove all inhabitants out of the village by a decision of the civil protection unit, and also other activities of the emergency relief units were overshadowed by the 7 victims. One of the main problems and challenges at the same time was the over 700,000 m³ of wet debris flow deposits in the area of the village of Log pod Mangartom within the Triglav National park, which posed a direct threat of flooding during the first heavy rainfalls in spring 2001, and which were about to be removed to make place for future debris flows. The understanding about what really happened or about the immediate triggering factors was different among the professionals in charge for relief action and for preparing a final remediation plan. The first phase during and immediately after the disaster (relief intervention of emergency units especially those for civil protection) can be described as Concern-Driven Crisis Management or

  13. Early object relations into new objects.

    Science.gov (United States)

    Downey, T W

    2001-01-01

    Two strands of change are suggested by this review, one maturational, the other therapeutic or developmental (Hartmann and Kris, 1945). By "maturational" I mean to suggest energies that infuse the individual from earliest life in a manner that includes object relations, but for the healthy exercise of which object relations per se need not be of central and crucial importance. Within wide limits such energies may be delayed until growth conditions prevail without significant distortion of certain of the organism's ego functions. Therapeutic change is analogous to developmental change in that both involve the crucial presence of another to release energies. In therapeutic change these are energies that have been repressed beyond the reach of developmental dynamics. In everyday development crisis and synthesis alternate in conjunction with new and emerging objects to add to the psychological structures brought to the fore by maturation. In many instances, as we see with John, over time and in a less focussed manner, developmental changes can approximate therapeutic change and visa versa. Freud-Dann in their "experiment" pursued one line, in which the equipmental delay brought on by extremely adverse living circumstances was redressed by providing an interpersonally enriching, loving, developmentally facilitating milieu. The sketches of individual children and John's subsequent story provide a perspective into what becomes the stuff of growth and what remains the stuff of neurosis. The developmental reserves and ego resilience of these children were impressive but probably not extraordinary. Usual growth ensued as soon as they were provided with the rich soil of Bulldogs Bank instead of the desert sand of the Tereszin concentration camp. However, no one can escape such adverse circumstances without having taken in the stuff of neurosis. Affects and percepts that were not assimilatable or even available to consciousness at the time remain buried in the unconscious

  16. Scaled-Free Objects

    CERN Document Server

    Grilliette, Will

    2010-01-01

    Several functional analysts and C*-algebraists have been moving toward a categorical means of understanding normed objects. In this work, I address a primary issue with adapting these abstract concepts to functional analytic settings, the lack of free objects. Using a new object, called a "crutched set", and associated categories, I devise generalized construction of normed objects as a left adjoint functor to a natural forgetful functor. Further, the universal property in each case yields a "scaled-free" mapping property, which extends previous notions of `"free" normed objects. In particular, I construct the following types of scaled-free objects: Banach spaces, Banach algebras, C*-algebras, operator spaces, and operator algebras. In subsequent papers, this scaled-free property, coupled with the associated functorial results, will give rise to a new view of presentation theory for C*-algebras, which inherits many properties and constructions from its algebraic counterpart.

    the thesis is more fashionable in the current debate than defending conceivability as anything but one psychological heuristic device among others with which we form beliefs about modality.

A number of these are problems for an epistemology of modality generally. I will focus on the objections that are peculiar to conceivability theses: the Standard Objection...... and the Uselessness Objection. The Standard Objection targets the second premise in an argument for possibility from conceivability, that what is conceived is possible, typically by offering counterexamples in the form of conceivable impossibilities. The Uselessness Objection targets the first premise in an argument...

  18. Reasoning about Function Objects

    Science.gov (United States)

    Nordio, Martin; Calcagno, Cristiano; Meyer, Bertrand; Müller, Peter; Tschannen, Julian

    Modern object-oriented languages support higher-order implementations through function objects such as delegates in C#, agents in Eiffel, or closures in Scala. Function objects bring a new level of abstraction to the object-oriented programming model, and require a comparable extension to specification and verification techniques. We introduce a verification methodology that extends function objects with auxiliary side-effect free (pure) methods to model logical artifacts: preconditions, postconditions and modifies clauses. These pure methods can be used to specify client code abstractly, that is, independently from specific instantiations of the function objects. To demonstrate the feasibility of our approach, we have implemented an automatic prover, which verifies several non-trivial examples.

  19. On Coordinating Collaborative Objects

    CERN Document Server

    Imine, Abdessamad

    2010-01-01

    A collaborative object represents a data type (such as a text document) designed to be shared by a group of dispersed users. The Operational Transformation (OT) is a coordination approach used for supporting optimistic replication for these objects. It allows the users to concurrently update the shared data and exchange their updates in any order since the convergence of all replicas, i.e. the fact that all users view the same data, is ensured in all cases. However, designing algorithms for achieving convergence with the OT approach is a critical and challenging issue. In this paper, we propose a formal compositional method for specifying complex collaborative objects. The most important feature of our method is that designing an OT algorithm for the composed collaborative object can be done by reusing the OT algorithms of component collaborative objects. By using our method, we can start from correct small collaborative objects which are relatively easy to handle and incrementally combine them to build more ...

    2016-01-01

    Conventional microscope objective lenses are diffraction limited, which means that they cannot resolve features smaller than half the illumination wavelength. Under white light illumination, such resolution limit is about 250-300 nm for an ordinary microscope. In this paper, we demonstrate a new superlensing objective lens which has a resolution of about 100 nm, offering at least two times resolution improvement over conventional objectives in resolution. This is achieved by integrating a conventional microscope objective lens with a superlensing microsphere lens using a 3D printed lens adaptor. The new objective lens was used for label-free super-resolution imaging of 100 nm-sized engineering and biological samples, including a Blu-ray disc sample, semiconductor chip and adenoviruses. Our work creates a solid base for developing a commercially-viable superlens prototype, which has potential to transform the field of optical microscopy and imaging.

Additionally, the initial location of the progenitors of the Kuiper belt objects also has a significant effect on binary formation.

Tracking is a natural follow-up of motion-based segmentation. It is a fast and efficient method to achieve coherent motion segments along the temporal axis. Segmenting out moving objects for each and every frame in a video sequence is a computationally expensive approach. Thus, for better performance, semi-automatic segmentation is an acceptable compromise as automatic segmentation approaches rely heavily on prior assumptions. In semi-automatic segmentation approaches, motion-segmentation is performed only on the initial frame and the moving object is tracked in subsequent frames using tracking algorithms. In this paper, a new model for object tracking is proposed, where the image features -- edges, intensity pattern, object motion and initial keyed-in contour (by the user) form the prior and likelihood model of a Markov Random Field (MRF) model. Iterated Conditional Mode (ICM) is used for the minimization of the global energy for the MRF model. The motion segment for each frame is initialized using the segment information from the previous frame. For the initial frame, the motion segment is obtained by manually keying in the object contour. The motion-segments obtained using the proposed model are coherent and accurate. Experimental results on tracking using the proposed algorithm for different sequences -- Bream, Alexis and Claire are presented in this paper. The results obtained are accurate and can be used for a variety of applications including MPEG-4 Video Object Plane (VOP) extraction.

  20. Unifying Subjectivity and Objectivity

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    Two southern objects are studied. The first, the planetary nebula PK 349-01.1, is of interest because it has a chain of jets ejected from the central star. 12C(1-0) observations of the vicinity of this object reveal red- and blue-shifted molecular outflows. The second object is a star formation region consisting of two groups of IR stars. These groups have a trapezium-like configuration. Two stars in one of these groups are associated with a ring-shaped nebulae. This star formation region is associated with a new radial system of dark globules.

    Therapeutic objectives for patients with atherogenic dyslipidemia are achieved by improving patient compliance and adherence. Clinical practice guidelines address the importance of treatment compliance for achieving objectives. The combination of a fixed dose of pravastatin and fenofibrate increases the adherence by simplifying the drug regimen and reducing the number of daily doses. The good tolerance, the cost of the combination and the possibility of adjusting the administration to the patient's lifestyle helps achieve the objectives for these patients with high cardiovascular risk.

  5. Direct manipulation of virtual objects

    Science.gov (United States)

    Nguyen, Long K.

    Interacting with a Virtual Environment (VE) generally requires the user to correctly perceive the relative position and orientation of virtual objects. For applications requiring interaction in personal space, the user may also need to accurately judge the position of the virtual object relative to that of a real object, for example, a virtual button and the user's real hand. This is difficult since VEs generally only provide a subset of the cues experienced in the real world. Complicating matters further, VEs presented by currently available visual displays may be inaccurate or distorted due to technological limitations. Fundamental physiological and psychological aspects of vision as they pertain to the task of object manipulation were thoroughly reviewed. Other sensory modalities -- proprioception, haptics, and audition -- and their cross-interactions with each other and with vision are briefly discussed. Visual display technologies, the primary component of any VE, were canvassed and compared. Current applications and research were gathered and categorized by different VE types and object interaction techniques. While object interaction research abounds in the literature, pockets of research gaps remain. Direct, dexterous, manual interaction with virtual objects in Mixed Reality (MR), where the real, seen hand accurately and effectively interacts with virtual objects, has not yet been fully quantified. An experimental test bed was designed to provide the highest accuracy attainable for salient visual cues in personal space. Optical alignment and user calibration were carefully performed. The test bed accommodated the full continuum of VE types and sensory modalities for comprehensive comparison studies. Experimental designs included two sets, each measuring depth perception and object interaction. The first set addressed the extreme end points of the Reality-Virtuality (R-V) continuum -- Immersive Virtual Environment (IVE) and Reality Environment (RE). This

    We present a method for directly modeling piles of objects in multi-body simulations. Piles of objects represent some of the more interesting, but also most time-consuming portion of simulation. We propose a method for reducing computation in many of these situations by explicitly modeling the piles that the objects may form into. By modeling pile behavior rather than the behavior of all individual objects, we can achieve realistic results in less time, and without directly modeling the frictional component that leads to desired pile shapes. Our method is simple to implement and can be easily integrated with existing rigid body simulations. We observe notable speedups in several rigid body examples, and generate a wider variety of piled structures than possible with strict impulse-based simulation. © 2010 ACM.

  9. This elusive objective existence

    CERN Document Server

    Mohrhoff, U

    2004-01-01

    Zurek's existential interpretation of quantum mechanics suffers from three classical prejudices, including the belief that space and time are intrinsically and infinitely differentiated. They compel him to relativize the concept of objective existence in two ways. The elimination of these prejudices makes it possible to recognize the quantum formalism's ontological implications - the relative and contingent reality of spatiotemporal distinctions and the extrinsic and finite spatiotemporal differentiation of the physical world - which in turn makes it possible to arrive at an unqualified objective existence. Contrary to a widespread misconception, viewing the quantum formalism as being fundamentally a probability algorithm does not imply that quantum mechanics is concerned with states of knowledge rather than states of Nature. On the contrary, it makes possible a complete and strongly objective description of the physical world that requires no reference to observers. What objectively exists, in a sense that r...

  14. Objects of consciousness.

    Hoffman, Donald D; Prakash, Chetan

    2014-01-01

    Current models of visual perception typically assume that human vision estimates true properties of physical objects, properties that exist even if unperceived. However, recent studies of perceptual evolution, using evolutionary games and genetic algorithms, reveal that natural selection often drives true perceptions to extinction when they compete with perceptions tuned to fitness rather than truth: Perception guides adaptive behavior; it does not estimate a preexisting physical truth. Moreover, shifting from evolutionary biology to quantum physics, there is reason to disbelieve in preexisting physical truths: Certain interpretations of quantum theory deny that dynamical properties of physical objects have definite values when unobserved. In some of these interpretations the observer is fundamental, and wave functions are compendia of subjective probabilities, not preexisting elements of physical reality. These two considerations, from evolutionary biology and quantum physics, suggest that current models of object perception require fundamental reformulation. Here we begin such a reformulation, starting with a formal model of consciousness that we call a "conscious agent." We develop the dynamics of interacting conscious agents, and study how the perception of objects and space-time can emerge from such dynamics. We show that one particular object, the quantum free particle, has a wave function that is identical in form to the harmonic functions that characterize the asymptotic dynamics of conscious agents; particles are vibrations not of strings but of interacting conscious agents. This allows us to reinterpret physical properties such as position, momentum, and energy as properties of interacting conscious agents, rather than as preexisting physical truths. We sketch how this approach might extend to the perception of relativistic quantum objects, and to classical objects of macroscopic scale.

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    2007-01-01

    Conscientious objection to democratically accepted laws in democratic societies is a fact, both among citizens and among professionals. Due respect for laws is a prima facie duty in these societies. But democratic justice must at the same time respect peoples' conscience for it constitutes the ethical identity of individuals. And both law and ethics are necessary - although neither of them is sufficient - for its realization. The problem of conscientious objection among healthcare professionals is analysed from this standpoint and the conclusion is that objection is not an absolute right to exemption from several duties, but that the responsibility of the professional and of the institutions towards the citizenry must always be taken into account. Some solutions are suggested that try to protect both the professionals and the citizens in a bi-directional way.

  17. Invariance and Objectivity

    Science.gov (United States)

    Vollmer, Gerhard

    2010-10-01

    Scientific knowledge should not only be true, it should be as objective as possible. It should refer to a reality independent of any subject. What can we use as a criterion of objectivity? Intersubjectivity (i.e., intersubjective understandability and intersubjective testability) is necessary, but not sufficient. Other criteria are: independence of reference system, independence of method, non-conventionality. Is there some common trait? Yes, there is: invariance under some specified transformations. Thus, we say: A proposition is objective only if its truth is invariant against a change in the conditions under which it was formulated. We give illustrations from geometry, perception, neurobiology, relativity theory, and quantum theory. Such an objectivist position has many advantages.

    An M7. 3 strong earthquake occurred in Port-au-Prince, Haiti on Jan. 12, 2010 has destroyed a large number of buildings. From the post-earthquake very high resolution remote sensing image, we can find there are a lot of rubbles around collapsed and partly damaged buildings. Therefore, we take these rubbles as seismic-damage characteristics of the collapsed buildings and use the following three methods-pixel-based method, object-oriented method and object-oriented method combined with geo-statistical texture to extract rubbles automatically. Finally , we assess the accuracy of the three classifications of the remotely-sensed data through the three methods. It turns out that the accuracy of pixel-based method is less than that of object-oriented method. The overall Kappa coefficient and user's precision of rubbles have improved remarkably when adding texture feature. However, there is no obvious improvement of the producer precision of the rubbles.%2010年1月12日海地发生7.3级大地震,造成首都太子港大量建筑物损毁.从震后甚高分辨率遥感影像中可以发现在倒塌和部分倒塌建筑物的周围存在很多瓦砾.因此,可以将瓦砾作为建筑物倒损的震害特征.分别采用基于像元的方法、面向对象的方法、综合地统计学纹理的面向对象方法自动提取建筑物瓦砾,并对3种方法的分类精度进行了评价,研究结果表明:单纯面向对象分类方法的总体分类精度低于基于像元的分类方法;当加入纹理特征后,总体Kappa系数和瓦砾的用广精度明显提高,然而瓦砾的生产者精度的改善并不明显.

  19. Million object spectrograph

    Ditto, Thomas D.; Ritter, Joseph M.

    2008-07-01

    A new class of astronomical telescope with a primary objective grating (POG) has been studied as an alternative to mirrors. Nineteenth century POG telescopes suffered from low resolution and ambiguity of overlapping spectra as well as background noise. The present design uses a conventional secondary spectrograph to disambiguate all objects while enjoying a very wide instantaneous field-of-view, up to 40°. The POG competes with mirrors, in part, because diffraction gratings provide the very chromatic dispersion that mirrors defeat. The resulting telescope deals effectively with long-standing restrictions on multiple object spectrographs (MOS). The combination of a POG operating in the first-order, coupled to a spectrographic astronomical telescope, isolates spectra from all objects in the free spectral range of the primary. First disclosed as a concept in year 2002, a physical proof-of-principle is now reported. The miniature laboratory model used a 50 mm plane grating primary and was able to disambiguate between objects appearing at angular resolutions of 55 arcseconds and spectral spacings of 0.15 nm. Astronomical performance is a matter of increasing instrument size. A POG configured according to our specifications has no moving parts during observations and is extensible to any length that can be held flat to tolerances approaching float glass. The resulting telescope could record over one million spectra per night of objects in a line of right ascension. The novel MOS does not require pre-imaging to start acquisition of uncharted star fields. Problems are anticipated in calibration and integration time. We propose means to ameliorate them.

    2015-01-01

    We define objective Eulerian Coherent Structures (OECSs) in two-dimensional, non-autonomous dynamical systems as instantaneously most influential material curves. Specifically, OECSs are stationary curves of the averaged instantaneous material stretching-rate or material shearing-rate functionals. From these objective (frame-invariant) variational principles, we obtain explicit differential equations for hyperbolic, elliptic and parabolic OECSs. As illustration, we compute OECSs in an unsteady ocean velocity data set. In comparison to structures suggested by other common Eulerian diagnostic tools, we find OECSs to be the correct short-term cores of observed trajectory deformation patterns.

Age and duration are usually expressed in units with varying lengths. The number of days in a month or a year depends on the position on the calendar. The units are also not homogeneous and the structure influences measurement. One solution, common in demography, is to use units that are large enough for the results not to be seriously affected by differences in length and structure. Another approach is to take the idiosyncrasy of calendars into account and to work directly with calendar dates. The technology that enables logical and arithmetic operations on dates is available. OBJECTIVE To illustrate logical and arithmetic operations on dates and conversions between time measurements. METHODS Software packages include utilities to process dates. I use existing and a few new utilities in R to illustrate operations on dates and conversions between calendar dates and elapsed time since a reference moment or a reference event. Three demographic applications are presented. The first is the impact of preferences for dates and days on demographic indicators. The second is event history analysis with time-varying covariates. The third is microsimulation of life histories in continuous time. CONCLUSIONS The technology exists to perform operations directly on dates, enabling more precise calculations of duration and elapsed time in demographic analysis. It eliminates the need for (a approximations and (b transformations of dates, such as Century Month Code, that are convenient for computing durations but are a barrier to interpretation. Operations on dates, such as the computation of age, should consider time units of varying length.

    I have recently become involved in the ABET certification process under the new system - ABET 2000. This system relies heavily on concepts of Total Quality Management (TQM). It encourages each institution to define its objectives in terms of its own mission and then create a coherent program based on it. The prescribed steps in setting up the new system at an engineering institution are: o identification of constituencies G definition of mission. It is expected that the department's mission will be consistent with that of the overall institution, but containing some higher resolution language appropriate to that particular discipline of the engineering profession. o statement of objectives consistent with the mission 3G~~\\vED " enumeration of desired, and preferably measurable, outcomes of the process that would ~ `=. verify satisfaction of the objectives. ~~~ 07 !398 o establish performance standards for each outcome. o creation of appropriate feedback loops to assure that the objectives are still consistent with Q$YT1 the mission, that the outcomes remain consistent with the objectives, and that the curriculum and the teaching result in those outcomes. It is my assertion that once the institution verbalizes a mission, enumerated objectives naturally flow from that mission. (We shall try to demonstrate by example.) Further, if the mission uses the word "engineer", one would expect that word also to appear in at least one of the objectives. The objective of producing engineers of any sort must -by decree - involve the presence of the ABET criteria in the outcomes list. In other words, successful satisfaction of the ABET items a-k are a necessary subset of the measure of success in producing engineers. o We shall produce bachelor level engineers whose training in the core topics of chemical (or electrical, or mechanical) engineering is recognized to be among the best in the nation. o We shall provide an opportunity for our students to gain

    The paradox of Wigner's friend challenges the objectivity of description in quantum theory. A pragmatist interpretation can meet this challenge by judicious appeal to decoherence. On this interpretation, quantum theory provides situated agents with resources for predicting and explaining what happens in the physical world---not conscious observations of it. Even in Wigner's friend scenarios, differently situated agents agree on the objective content of statements about the values of physical magnitudes. In more realistic circumstances quantum Darwinism also permits differently situated agents equal observational access to evaluate their truth. In this view, quantum theory has nothing to say about consciousness or conscious experiences of observers. But it does prompt us to reexamine the significance even of everyday claims about the physical world.

    The law regulating abortion in Italy gives healthcare practitioners the option to make a conscientious objection to activities that are specific and necessary to an abortive intervention. Conscientious objectors among Italian gynaecologists amount to about 70%. This means that only a few doctors are available to perform abortions, and therefore access to abortion is subject to constraints. In 2012 the International Planned Parenthood Federation European Network (IPPF EN) lodged a complaint against Italy to the European Committee of Social Rights, claiming that the inadequate protection of the right to access abortion implies a violation of the right to health. In this paper I will discuss the Italian situation with respect to conscientious objection to abortion and I will suggest possible solutions to the problem.

    This report describes the use and implementation of DOLIB (Distributed Object Library), a library of routines that emulates global or virtual shared memory on Intel multiprocessor systems. Access to a distributed global array is through explicit calls to gather and scatter. Advantages of using DOLIB include: dynamic allocation and freeing of huge (gigabyte) distributed arrays, both C and FORTRAN callable interfaces, and the ability to mix shared-memory and message-passing programming models for ease of use and optimal performance. DOLIB is independent of language and compiler extensions and requires no special operating system support. DOLIB also supports automatic caching of read-only data for high performance. The virtual shared memory support provided in DOLIB is well suited for implementing Lagrangian particle tracking techniques. We have also used DOLIB to create DONIO (Distributed Object Network I/O Library), which obtains over a 10-fold improvement in disk I/O performance on the Intel Paragon.

    Full Text Available Digital medical informatics and images are commonly used in hospitals today. Because of the interrelatedness of the radiology department and other departments, especially the intensive care unit and emergency department, the transmission and sharing of medical images has become a critical issue. Our research group has developed a Java-based Distributed Object Medical Imaging Model(DOMIM to facilitate the rapid development and deployment of medical imaging applications in a distributed environment that can be shared and used by related departments and mobile physiciansDOMIM is a unique suite of multimedia telemedicine applications developed for the use by medical related organizations. The applications support realtime patients' data, image files, audio and video diagnosis annotation exchanges. The DOMIM enables joint collaboration between radiologists and physicians while they are at distant geographical locations. The DOMIM environment consists of heterogeneous, autonomous, and legacy resources. The Common Object Request Broker Architecture (CORBA, Java Database Connectivity (JDBC, and Java language provide the capability to combine the DOMIM resources into an integrated, interoperable, and scalable system. The underneath technology, including IDL ORB, Event Service, IIOP JDBC/ODBC, legacy system wrapping and Java implementation are explored. This paper explores a distributed collaborative CORBA/JDBC based framework that will enhance medical information management requirements and development. It encompasses a new paradigm for the delivery of health services that requires process reengineering, cultural changes, as well as organizational changes.

    Full Text Available EXTENDED ABSTRACT:The first and important phase of documentation of cultural heritage objects is to understand which objects need to be documented. The entire documentation process is determined by the characteristics and scope of the cultural heritage object. The next question to be considered is the expected outcome of the documentation process and the purpose for which it will be used. These two essential guidelines determine each stage of the documentation workflow: the choice of the most appropriate data capturing technology and data processing method, how detailed should the documentation be, what problems may occur, what the expected outcome is, what it will be used for, and the plan for storing data and results. Cultural heritage objects require diverse data capturing and data processing methods. It is important that even the first stages of raw data capturing are oriented towards the applicability of results. The selection of the appropriate working method can facilitate the data processing and the preparation of final documentation. Documentation of paintings requires different data capturing method than documentation of buildings or building areas. The purpose of documentation can also be the preservation of the contemporary cultural heritage to posterity or the basis for future projects and activities on threatened objects. Documentation procedures should be adapted to our needs and capabilities. Captured and unprocessed data are lost unless accompanied by additional analyses and interpretations. Information on tools, procedures and outcomes must be included into documentation. A thorough analysis of unprocessed but accessible documentation, if adequately stored and accompanied by additional information, enables us to gather useful data. In this way it is possible to upgrade the existing documentation and to avoid data duplication or unintentional misleading of users. The documentation should be archived safely and in a way to meet

    The postmodern theory of Baudrillard is a technological determinism, he constructed a simulational world that derived from the model and code, DNA and the binary digital 0/1 is the original of the world. Under the reign of high-technology,subject became creation through technology and lost the richness and diversity. Owing to the powerful of the technology, the realm of object controlled and dominated the human society. Then Baudrillard proposed a passive fatalism, and believed the objective system would develop to perfection and extreme, accordingly im- plode and reverse. Baudrillard's theory is helpful when we reflect the increasingly natural disasters and technological crisis, it also provide a great insight when we rethink the relationship between human and technology.%鲍德里亚的后现代理论是一种典型的技术决定论,他构建了一个由模型、符码所生成的拟真世界,在那里DNA和0/1数字具有了本体论意义。在高科技的世界里,主体失去了丰富而多样的存在,成为技术的创造物和附属物。伴随着主体衰落而产生的是客体的兴盛与强大,客体世界开始控制并主宰着人类社会的运行。鲍德里亚由此提出一种消极的宿命论,即客体系统自身发展到完美、极致,并在顶点上自动内爆、反转。鲍德里亚的理论对于我们反思日益频繁的自然灾害和技术危机、对于重新考量人与自然、技术之间关系提供了有益的启示。

    Science.gov (United States)

    Ford, Natalie J; Fraser, Kimberly D; Marck, Patricia B

    2010-09-01

    In this paper we argue that nurse leaders need to work actively to create morally supportive environments for nurses in Canada that provide adequate room to exercise conscientious objection. Morally supportive environments engender a safe atmosphere to engage in open dialogue and action regarding conflict of conscience. The CNA's 2008 Code of Ethics for Registered Nurses has recognized the importance of conscientious objection in nursing and has created key guidelines for the registered nurse to follow when a conflict in conscience is being considered or declared. Nurse leaders need to further develop the understanding of conflicts of conscience through education, well-written guidelines for conscientious objection in workplaces and engagement in research to uncover underlying barriers to the enactment of conscientious objections. With advancements in technology, changing healthcare policies and increasing scope of practice, both reflection and dialogue on conscientious objection are critical for the continuing moral development of nurses in Canada.

In contrast, object database systems are built to handle such complexity, but do not support OLAP-type querying well. This paper presents the concepts and techniques underlying a flexible, multi-model federated system...... that enables OLAP users to exploit simultaneously the features of OLAP and object systems. The system allows data to be handled using the most appropriate data model and technology: OLAP systems for dimensional data and object database systems for more complex, general data. Additionally, physical data...... integration can be avoided. As a vehicle for demonstrating the capabilities of the system, a prototypical OLAP language is defined and extended to naturally support queries that involve data in object databases. The language permits selection criteria that reference object data, queries that return...

    The development of software systems for the biosciences is always closely connected to experimental practice. Programs must be able to handle the inherent complexity and heterogeneous structure of biological systems in combination with the measuring equipment. Moreover, a high degree of flexibility is required to treat rapidly changing experimental conditions. Object-oriented methodology seems to be well suited for this purpose. It enables an evolutionary approach to software development that still maintains a high degree of modularity. This paper presents experience with object-oriented technology gathered during several years of programming in the fields of bioprocess development and metabolic engineering. It concentrates on the aspects of experimental support, data analysis, interaction and visualization. Several examples are presented and discussed in the general context of the experimental cycle of knowledge acquisition, thus pointing out the benefits and problems of object-oriented technology in the specific application field of the biosciences. Finally, some strategies for future development are described.

  16. War Journalism and 'Objectivity'

    Directory of Open Access Journals (Sweden)

    Annabel McGoldrick

    2006-10-01

    Full Text Available This article opens by considering an apparent paradox. Many professional journalists, working on many media in many countries, consider themselves 'objective'. They do not, at least, set out to skew their coverage of important issues in favour of one side or the other. And yet much of their coverage of conflicts shows a discernible dominant pattern of War Journalism - biased in favour of war. This is not because of a lack of objectivity, the article suggests, but a surfeit. The set of conventions many editors and reporters regard as defining 'objective' journalism arose in response to economic and political conditions which rewarded news that could commend itself as unobjectionable to the maximum number of potential customers. Three of the most important conventions privilege official sources; a dualistic construction of stories and event, over process. Each of these, when applied to the representation of conflicts, leads readers and audiences - or leaves them - to over-value violent, reactive responses and under-value non-violent, developmental responses. Industry conventions sit uneasily alongside equally time-honoured expectations of journalism. These are encoded in rules and regulations governing the content of broadcast news, in many jurisdictions which have a public service concept for radio and television. In some respects, War Journalism can be shown to make it more difficult for broadcast news services to fulfil their public service obligations. Awareness is now growing, of the tension between these two pressures on journalism and its influence on the way pressing public debates are shaped and mediated. More Peace Journalism would help to bring public service news back into line with legitimate public expectations.

    Full Text Available A preon-based composite model of the fundamental fermions is discussed, in which the fermions are bound states of smaller entities — primitive charges (preons. The preon is regarded as a dislocation in a dual 3-dimensional manifold — a topological object with no properties, save its unit mass and unit charge. It is shown that the dualism of this manifold gives rise to a hierarchy of complex structures resembling by their properties three families of the fundamental fermions. Although just a scheme for building a model of elementary particles, this description yields a quantitative explanation of many observable particle properties, including their masses.

    2002-01-01

    A conceptual preon-based model of fermions is discussed. The preon is regarded as a topological object with three degrees of freedom in a dual three-dimensional manifold. It is shown that properties of this manifold give rise to a set of preon structures, which resemble three families of fermions. The number of preons in each structure is easily associated with the mass of a fermion. Being just a kind of zero-approximation to a theory of particles and interactions below the quark scale, our model however predicts masses of fermions with an accuracy of about 0.0002% without using any experimental input parameters.

    Clarke, Steve; Giubilini, Alberto; Walker, Mary Jean

    2017-03-01

    Vaccine refusal occurs for a variety of reasons. In this article we examine vaccine refusals that are made on conscientious grounds; that is, for religious, moral, or philosophical reasons. We focus on two questions: first, whether people should be entitled to conscientiously object to vaccination against contagious diseases (either for themselves or for their children); second, if so, to what constraints or requirements should conscientious objection (CO) to vaccination be subject. To address these questions, we consider an analogy between CO to vaccination and CO to military service. We argue that conscientious objectors to vaccination should make an appropriate contribution to society in lieu of being vaccinated. The contribution to be made will depend on the severity of the relevant disease(s), its morbidity, and also the likelihood that vaccine refusal will lead to harm. In particular, the contribution required will depend on whether the rate of CO in a given population threatens herd immunity to the disease in question: for severe or highly contagious diseases, if the population rate of CO becomes high enough to threaten herd immunity, the requirements for CO could become so onerous that CO, though in principle permissible, would be de facto impermissible.

    Paletta, Lucas; Goyal, Anurag; Greindl, Christian

    2003-03-01

    Object detection is an enabling technology that plays a key role in many application areas, such as content based media retrieval. Attentive cognitive vision systems are here proposed where the focus of attention is directed towards the most relevant target. The most promising information is interpreted in a sequential process that dynamically makes use of knowledge and that enables spatial reasoning on the local object information. The presented work proposes an innovative application of attention mechanisms for object detection which is most general in its understanding of information and action selection. The attentive detection system uses a cascade of increasingly complex classifiers for the stepwise identification of regions of interest (ROIs) and recursively refined object hypotheses. While the most coarse classifiers are used to determine first approximations on a region of interest in the input image, more complex classifiers are used for more refined ROIs to give more confident estimates. Objects are modelled by local appearance based representations and in terms of posterior distributions of the object samples in eigenspace. The discrimination function to discern between objects is modeled by a radial basis functions (RBF) network that has been compared with alternative networks and been proved consistent and superior to other artifical neural networks for appearance based object recognition. The experiments were led for the automatic detection of brand objects in Formula One broadcasts within the European Commission's cognitive vision project DETECT.

    : The aim of the Egyptsat series is to build on the experience gained from these missions to extend Egypt's space effort into scientific research and to expand its role in educational, agricultural and other development fields. The Egyptian Space Programme envisages that Egypt will be able to join the space age through the gradual establishment of the facilities needed for the manufacture of small research and remote sensing satellites, by acquiring appropriate technological knowledge and capabilities, and by building up the necessary infrastructure to enable the country to design and manufacture its own small satellites. Included in this overall vision would be the capacity to utilize space technologies And applications to serve the national development plans and contribute to the development of scientific and technological research in Egypt, as well as to the establishment of a scientific and research base for advanced industries in Egypt. To hasten the achievement of some or all of these objectives, it will be necessary to: • Transfer advanced space technologies in communication, computers, programs, optics, sensors, new materials, command and control, and energy into the domain of the Egyptian scientific community. • Utilize space technologies and apply these to the country's development plans. • Acquire national capabilities in space technology disciplines. Establish scientific and industrial base in advanced technology fields. • Enhance our human resource capabilities for space sciences fields. • Promote cooperation between the country's research and industrial centres in order to bring about successful project within the national space programme.

    Objective perimetry in glaucoma is described using the multifocal pattern visually evoked potential (VEP). A multichannel recording technique was used to improve signal detection in healthy volunteers and assess its ability to detect glaucoma and early changes in patients with suspected glaucoma. Prospective, case-control study. Thirty healthy volunteers, 30 patients with suspected glaucoma, and 30 patients with glaucomatous visual field defects were tested. The VEP was recorded using cortically scaled, multifocal, pseudorandomly alternated pattern stimuli with the VERIS system (Electro-Diagnostic Imaging, Inc., San Francisco, CA). An array of four bipolar occipital electrodes provided four differently oriented channels for simultaneous recording. Signals were compared for different locations within the field up to 26 degrees of eccentricity. Healthy volunteers, patients with suspected glaucoma, and glaucoma patients with established visual field defects were tested, and results were compared with Humphrey visual fields (Humphrey Systems, Dublin, CA) performed on the same day. For reproducibility, five healthy volunteers were each tested on four separate days. The patients with suspected glaucoma and the established glaucoma patients were analyzed for intereye asymmetry of signals, and these data were compared with the asymmetry values of the healthy volunteers. Multiple recording channels significantly enhanced the recording of signals from parts of the visual field not reliably sampled with a single channel technique in all healthy volunteers, particularly along the horizontal meridian (P: < 0.001). Signal amplitude did not decline with age in healthy volunteers. Recordings showed good reproducibility within individuals. In all 30 glaucoma patients, the Humphrey visual field defects were well demonstrated by the VEP, and topographic location was strongly correlated (r(s) = 0.79). Despite large interindividual variations in amplitude, scotomas were well

    Full Text Available Raising of problem. Today, in all spheres of our life we can constate the permanent search for new, modern methods and technologies that meet the principles of sustainable development. New approaches need to be, on the one hand more effective in terms of conservation of exhaustible resources of our planet, have minimal impact on the environment and on the other hand to ensure a higher quality of the final product. Construction is not exception. One of the new promising technology is the technology of 3D -printing of individual structures and buildings in general. 3Dprinting - is the process of real object recreating on the model of 3D. Unlike conventional printer which prints information on a sheet of paper, 3D-printer allows you to display three-dimensional information, i.e. creates certain physical objects. Currently, 3D-printer finds its application in many areas of production: machine building elements, a variety of layouts, interior elements, various items. But due to the fact that this technology is fairly new, it requires the creation of detailed and accurate technologies, efficient equipment and materials, and development of common vocabulary and regulatory framework in this field. Research Aim. The analysis of existing methods of creating physical objects using 3D-printing and the improvement of technology and equipment for the printing of buildings and structures. Conclusion. 3D-printers building is a new generation of equipment for the construction of buildings, structures, and structural elements. A variety of building printing technics opens up wide range of opportunities in the construction industry. At this stage, printers design allows to create low-rise buildings of different configurations with different mortars. The scientific novelty of this work is to develop proposals to improve the thermal insulation properties of constructed 3D-printing objects and technological equipment.

  8. Breaking object correspondence across saccadic eye movements deteriorates object recognition

    Directory of Open Access Journals (Sweden)

    Christian H. Poth

    2015-12-01

    Full Text Available Visual perception is based on information processing during periods of eye fixations that are interrupted by fast saccadic eye movements. The ability to sample and relate information on task-relevant objects across fixations implies that correspondence between presaccadic and postsaccadic objects is established. Postsaccadic object information usually updates and overwrites information on the corresponding presaccadic object. The presaccadic object representation is then lost. In contrast, the presaccadic object is conserved when object correspondence is broken. This helps transsaccadic memory but it may impose attentional costs on object recognition. Therefore, we investigated how breaking object correspondence across the saccade affects postsaccadic object recognition. In Experiment 1, object correspondence was broken by a brief postsaccadic blank screen. Observers made a saccade to a peripheral object which was displaced during the saccade. This object reappeared either immediately after the saccade or after the blank screen. Within the postsaccadic object, a letter was briefly presented (terminated by a mask. Observers reported displacement direction and letter identity in different blocks. Breaking object correspondence by blanking improved displacement identification but deteriorated postsaccadic letter recognition. In Experiment 2, object correspondence was broken by changing the object’s contrast-polarity. There were no object displacements and observers only reported letter identity. Again, breaking object correspondence deteriorated postsaccadic letter recognition. These findings identify transsaccadic object correspondence as a key determinant of object recognition across the saccade. This is in line with the recent hypothesis that breaking object correspondence results in separate representations of presaccadic and postsaccadic objects which then compete for limited attentional processing resources (Schneider, 2013. Postsaccadic

By the way learning objects reusability is achieving economic benefits from educational technology as it saving time and improving quality, but in case of choosing unsuitable learning object it may be less benefit than creating the learning object from scratch. Actually learning objects reusability can facilitate systems development and adaptation. By surveying the current evaluation metrics, we found that while they cover essential aspects, they enables all reviewers of learning objects to evaluate all criteria without paying attention to their roles in creating the learning object which affect their capability to evaluate specific criteria. Our proposed Approach (LOREM is evaluating learning objects based on a group of Aspects which measure their level of effectiveness in order to be reused in other contexts. LOREM classifies reviewers into 3 categories; 1. Academic Group: (Subject Expert Matter “SME” and Instructor. 2. Technical Group: (Instructional Designer “ID”, LO Developer and LO Designer. 3. Students group. The authorization of reviewers in these several categories are differentiated according to reviewer's type, e.g., (Instructor, LO Developer and their area of expert (their expertise subjects for academic and students reviewers.

    Polish laws specify the parties responsible for lawful medical care in the availability of abortion differently than the Resolution of the Council of Europe. According to Polish regulations they include all Polish doctors while according to the Resolution, the state. Polish rules should not discriminate against anyone in connection with his religion or belief, even more so because the issue of abortion is an example of an unresolved ethical dispute. The number of lawful abortion in Poland does not exceed 1000 per year and can be carried out by only a few specialists contracted by the National Health Fund. Sufficient information and assistance should be provided to all pregnant women by the National Health Fund. The participation of all physicians in the informing process is not necessary, as evidenced by the lack of complaints to provide information on where in vitro fertilization treatment can be found - until recently only available when paid for by the individual and performed in much larger numbers than abortion. Entities performing this paid procedure made sure to provide information on their own. The rejection of the right to the conscientious objection clause by negating the right to refuse information may lead some to give up the profession or cause the termination of certain professionals on the basis of the professed worldview. Meanwhile, doctors are not allowed to be discriminated against on the basis of their conscience or religion.

  11. Data quality objectives

    1993-12-31

    The U.S. Environmental Protection Agency (EPA) spends about $500 million annually in collecting environmental data for scientific research and regulatory decision making. In addition, the regulated community may spend as much as ten times more each year in responding to EPA compliance requirements. Among the EPA and the regulated community there are several important common concerns: both want to make informed decisions using the right type, quality, and quantity of data. Collecting new data is very resource intensive to all parties. Neither EPA nor the regulated community can afford to collect more or {open_quotes}better{close_quotes} data than are really needed; the Data Quality Objectives (DQO) process is a systematic planning tool for ensuring that the right data will be collected for arriving at a decision within the desired confidence constraints. Using the DQO process to plan environmental data collections can help improve their effectiveness and efficiency, and enhance the defensibility of the decisions for which the data are used.

    The essence of the method of biodialysis (hemodialysis with biological object) developed and suggested by the authors for clinical use consists in that the healthy organism exerts, through a system of mass transfer, a therapeutic action on the sick organism. Blood from the affected and healthy organisms is perfused through individual mass exchangers (dialyzers, hemodiafilters and hemofilters), which are hydraulically connected by a circulating transport medium. Metabolites that accumulate in blood of the affected organism diffuse into the transport medium and, from there, into blood of the healthy organism, which metabolizes them. The reverse process occurs simultaneously: substances, whose concentration in blood of the sick organism is less versus the healthy organism, diffuse from blood of the healthy organism to blood of patient. The method suggested by us can be used in clinical practice for normalizing a variety of parameters in patients with hepatic and renal insufficiency. Besides, a number of substances can be transferred from the healthy donor to patient in the process of biodialysis, which opens promising potentialities for the treatment of many diseases.

    We report B, V, and R magnitudes for scattered disk objects and centaurs from observations taken in December 2011 and August 2013 using the Lowell Observatory Perkins Telescope with PRISM and observations taken in March 2012 at the Vatican Advanced Technology Telescope (VATT) on Mt. Graham, Arizona. Targeted scattered disk objects include 2002 CY224, 2003 UY117, 2006 QJ181, 2008 CT190, 2009 YG19, 2010 FD49, 2010 VZ98. Targeted centaurs include 2002 QX47, 2005 UJ438, 2006 UX184, and 2007 RH283. We will determine if the resultant centaur colors follow the bimodal distribution (B-R either red or gray) previously detected. We will also compare the resultant scattered disk object colors to those published for other scattered disk objects. This work is based on observations with the Perkins Telescope at Lowell Observatory, and with the VATT: The Alice P. Lennon Telescope and the Thomas J. Bannan Astrophysics Facility.

    Full Text Available There is an on-going debate amongst linguists regarding the status of the object marker (OM. Some scholars argue that OMs are agreement morphology (Baker 2010, Riedel 2009 while others argue that OMs are pronominal and not agreement morphology (Nevins 2010, Kramer, under review, Labelle 2007, Demuth and Johnson 1990, Mchombo 2002. The purpose of this paper is to contribute to this debate using data from Ikalanga to support the view that OMs are pronominal clitics. I discuss evidence in favor of the agreement analysis as well as that in favor of the pronominal analysis. OMs in Ikalanga behave like agreement morphology in that they attach only to the verbal stem, only one OM occurs in a clause, and they share grammatical features (person, gender and number with the lexical NP with which they co-refer. However, there are many ways in which OMs behave like pronominals. For example, OMs do not vary in form according to the mood of a sentence or negation while subject markers, which I analyze as agreement morphemes do. They are not obligatory in Ikalanga sentences while subject markers are. OMs are not subject to locality constraints while agreement is. They can be bound by the subject (backward pronominalization, something unexpected of agreement and there is ample evidence to show that the lexical NP with which the OM co-refers is an adjunct, a fact which has been used in the literature to argue that the OM is pronominal in such a set up. The evidence in favor of the pronominal analysis however, is more compelling and therefore I conclude that OMs are pronominal clitics and not agreement morphology.

    A new technique of manipulating with fullerene C60 over graphene on a SiO2 substrate is proposed. To stop the chaotic motion of molecules and limit its range, it is suggested to use a corrugated substrate. The study has shown that, at the corrugation wavelength of 3.4 nm and depth of 1.6 nm, the fullerene motion becomes directed with a deviation within 0.5 nm. The fullerene motion becomes even more definite, with a deviation from a straight line within tenths of an angstrom by the action of an external electric field, which allows one to manipulate the motion along the bottom of a groove. The method proposed can serve as a basis for the controlled assembly of molecules to supermolecular structures of given configurations, which can be applied in bio- and nanoelectronics.

Object –Oriented approach are driving the current development of ODBMS that will handle complex objects, inheritance and other features that enable direct implementation technology that is being extended to combine data management capabilities with application of logical rules to provide more refined information to management. Object-oriented approach is used in different areas i.e Software Engg, Database Management System and Latest Approach is used in Data warehouse. Object-Oriented envelopment involves more than learning a program, it includes capability for development. A purely Object –Oriented tool like Java, Smalltalk , or the object –oriented use of C++ requires that problem domains be conceptualized in terms of the paradigm inherent in object technology. Most research in Object-oriented programming (OOP including object –oriented database Management systems (OODBMS, is concerned with supporting users which are not served well by more conventional technology. Our research has been from a different point of view – our primary motivating factor is toshow how existing applications can be enhanced using object –oriented Technology.

  1. Technologies as incarnated action

    Schraube, Ernst

    Contemporary conceptualizations of technology go beyond the traditional interpretation of created things as simply neutral means to an end. They theorize technologies as objects, which embody regimes of power (the theory of technological politics), or scripts (actor-network theory), or values...... (critical theory of technology), or patriarchal thought structures (feminist theories of technology). As helpful as these theories may be to understand the inner relationship between the technosphere and human life, the way in which the life of the individuals in the world of things is imagined remains...... vague and imprecise. In this paper I will argue for a social theory of technology, which includes the subjective and intersubjective implications of technological artifacts. I will show how acting has shifted from the province of human subjects to the sphere of work and products. The created things now...

  10. Object-Interviews: Folding, Unfolding, and Refolding Perceptions of Objects

    Directory of Open Access Journals (Sweden)

    Susan Naomi Nordstrom PhD

    2013-02-01

    Full Text Available This article describes the object-interview as a Deleuzian space in which subjects and objects, living and nonliving, entangle together. I developed the object-interview to understand the connections that 11 Midwestern family history genealogists made between objects (e.g., documents, photographs, and other artifacts and their ancestors. The object-interview suggests an alternative way to think and do qualitative interviews informed by poststructural theories. The method draws on French philosopher Deleuze's concepts of the fold, events, and a life, as well as conventional qualitative interview literature. Deleuze's concepts offer a way to rethink objects and subjects as fibrous, connective, and folding entities in qualitative interviews. Such a rethinking offers an alternative to subject-centered conventional qualitative interviews in which subjects are teased apart from objects and subjects primarily produce knowledge. The object-interview, then, is a Deleuzian space in which the supposed distinctions between subjects and objects, as well as other binary divisions, become indistinct, or entangled, as both subjects and objects produce knowledge. That space enabled me to create the concept ensemble of life—a constantly shifting group of objects associated with a person's life. In this article, I describe the theoretical entanglement of the object-interview, the object-interview itself, the data it produced in my dissertation study, and the significance of the method to the field of qualitative research methods.

  11. Adobe Boxes: Locating Object Proposals Using Object Adobes.

    2016-09-01

    Despite the previous efforts of object proposals, the detection rates of the existing approaches are still not satisfactory enough. To address this, we propose Adobe Boxes to efficiently locate the potential objects with fewer proposals, in terms of searching the object adobes that are the salient object parts easy to be perceived. Because of the visual difference between the object and its surroundings, an object adobe obtained from the local region has a high probability to be a part of an object, which is capable of depicting the locative information of the proto-object. Our approach comprises of three main procedures. First, the coarse object proposals are acquired by employing randomly sampled windows. Then, based on local-contrast analysis, the object adobes are identified within the enlarged bounding boxes that correspond to the coarse proposals. The final object proposals are obtained by converging the bounding boxes to tightly surround the object adobes. Meanwhile, our object adobes can also refine the detection rate of most state-of-the-art methods as a refinement approach. The extensive experiments on four challenging datasets (PASCAL VOC2007, VOC2010, VOC2012, and ILSVRC2014) demonstrate that the detection rate of our approach generally outperforms the state-of-the-art methods, especially with relatively small number of proposals. The average time consumed on one image is about 48 ms, which nearly meets the real-time requirement.

    Flexible and performant Persistency Service is a necessary component of any HEP Software Framework. The building of a modular, non-intrusive and performant persistency component have been shown to be very difficult task. In the past, it was very often necessary to sacrifice modularity to achieve acceptable performance. This resulted in the strong dependency of the overall Frameworks on their Persistency subsystems. Recent development in software technology has made possible to build a Persistency Service which can be transparently used from other Frameworks. Such Service doesn't force a strong architectural constraints on the overall Framework Architecture, while satisfying high performance requirements. Java Data Object standard (JDO) has been already implemented for almost all major databases. It provides truly transparent persistency for any Java object (both internal and external). Objects in other languages can be handled via transparent proxies. Being only a thin layer on top of a used database, JDO doe...

    The benefits of object-oriented technology are widely recognized in software engineering. This paper describes the use of the object-oriented paradigm to create distributed simulations. The University of Essex Robotics and Intelligent Machines group has been carrying out research into distributed vehicle simulation since 1992. Part of this research has focused on the development of simulation systems to assist in the design of robotic vehicles. This paper describes the evolution of these systems, from an early toolkit used for teaching robotics to recent work on using simulation as a design tool in the creation of a new generation of unmanned underwater vehicles. It outlines experiences gained in using PVM, and ongoing research into the use of the emerging High Level Architecture as the basis for these frameworks. The paper concludes with the perceived benefits of adopting object-oriented methodologies as the basis for simulation frameworks.

    The analysis of radiation danger of the Exclusion Zone objects was made. Here, the Zone is defined as the territory from which the population has been evacuated in 1986 owing to the Chernobyl accident and possible outflow of the contaminated substances out of the borders is potentially dangerous to the Ukraine. In the present work were analyzed such problems as sources of radiation danger in the Zone, ways of radionuclide migration out of the borders of the Zone in normal and emergency situations, the non-radiation (ecological) danger factors of the Zone objects, doses (individual and collective) from various sources and on separate ways of their formation, and the characteristics of radiation danger of the Zone objects. The conclusions are: (1) Radionuclide flows both from technologic and natural sources exceed those from Shelter objects, (2) Under emergency conditions, radionuclide flows and doze loading remain comparable with those from emergency sources, (3) To solve some management tasks in radiation situation, the basic works on the Shelter objects should be oriented to decrease probability of emergency occurrence and to reduce radiation influence (prevention wash-outs during high waters, fire-prevention measures in forests and strengthening of the control behind non-authorized use of objects in the Zone).

    Waste incineration is the art of completely combusting waste, while maintaining or reducing emission levels below current emission standards. Where possible, objectives include the recovering of energy as well as the  combustion residues.  Successful waste incineration makes it possible to achieve a deep reduction in waste volume, obtain a compact and sterile residue, and eliminate a wide array of pollutants. This book places waste incineration within the wider context of waste management, and demonstrates that, in contrast to landfills and composting, waste incineration can eliminate objectionable and hazardous properties such as flammability and toxicity, result in a significant reduction in volume, and destroy gaseous and liquid waste streams leaving little or no residues beyond those linked to flue gas neutralization and treatment. Moreover, waste incineration sterilizes and destroys putrescible matter, and produces usable heat.  Incineration Technologies first appeared as a peer-reviewed contribution ...

    Archaeology takes the material remains of human activity as the research object, and uses those fragmentary remains to reconstruct the humanistic and natural environment in different historical periods. Space Archaeology is a new branch of the Archaeology. Its study object is the humanistic-natural complex including the remains of human activities and living environments on the earth surface. The research method, space information technologies applied to this complex, is an innovative process concerning archaeological information acquisition, interpretation and reconstruction, and to achieve the 3-D dynamic reconstruction of cultural heritages by constructing the digital cultural-heritage sphere. Space archaeology's attribute is highly interdisciplinary linking several areas of natural and social and humanities. Its task is to reveal the history, characteristics, and patterns of human activities in the past, as well as to understand the evolutionary processes guiding the relationship between human and their environment. This paper summarizes six important aspects of space archaeology and five crucial recommendations for the establishment and development of this new discipline. The six important aspects are: (1) technologies and methods for non-destructive detection of archaeological sites; (2) space technologies for the protection and monitoring of cultural heritages; (3) digital environmental reconstruction of archaeological sites; (4) spatial data storage and data mining of cultural heritages; (5) virtual archaeology, digital reproduction and public information and presentation system; and (6) the construction of scientific platform of digital cultural-heritage sphere. The five key recommendations for establishing the discipline of Space Archaeology are: (1) encouraging the full integration of the strengths of both archaeology and museology with space technology to promote the development of space technologies' application for cultural heritages; (2) a new

    Although some studies have shown that haptic and visual identification seem to rely on similar processes, few studies have directly compared the two. We investigated haptic and visual object identification by asking participants to learn to recognize (Experiments 1, and 3), or to match (Experiment 2) novel objects that varied only in shape. Participants explored objects haptically, visually, or bimodally, and were then asked to identify objects haptically and/or visually. We demonstrated that patterns of identification errors were similar across identification modality, independently of learning and testing condition, suggesting that the haptic and visual representations in memory were similar. We also demonstrated that identification performance depended on both learning and testing conditions: visual identification surpassed haptic identification only when participants explored the objects visually or bimodally. When participants explored the objects haptically, haptic and visual identification were equivalent. Interestingly, when participants were simultaneously presented with two objects (one was presented haptically, and one was presented visually), object similarity only influenced performance when participants were asked to indicate whether the two objects were the same, or when participants had learned about the objects visually-without any haptic input. The results suggest that haptic and visual object representations rely on similar processes, that they may be shared, and that visual processing may not always lead to the best performance.

  3. Minimum Delay Moving Object Detection

    KAUST Repository

    Lao, Dong

    We present a general framework and method for detection of an object in a video based on apparent motion. The object moves relative to background motion at some unknown time in the video, and the goal is to detect and segment the object as soon it moves in an online manner. Due to unreliability of motion between frames, more than two frames are needed to reliably detect the object. Our method is designed to detect the object(s) with minimum delay, i.e., frames after the object moves, constraining the false alarms. Experiments on a new extensive dataset for moving object detection show that our method achieves less delay for all false alarm constraints than existing state-of-the-art.

    We present the Smart Object, Dumb Archive (SODA) model for digital libraries (DLs). The SODA model transfers functionality traditionally associated with archives to the archived objects themselves. We are exploiting this shift of responsibility to facilitate other DL goals, such as interoperability, object intelligence and mobility, and heterogeneity. Objects in a SODA DL negotiate presentation of content and handle their own terms and conditions. In this paper we present implementations of our smart objects, buckets, and our dumb archive (DA). We discuss the status of buckets and DA and how they are used in a variety of DL projects.

    Full Text Available Now-a-days, to access any information is not the problem. Internet facilitated the users to have any graphics or textual data at any time any where. Multimedia data is the key player in information transmission and retrieval domain. Multimedia processing is involved in the key areas like business, entertainment, technology, games, and advertisement etc. To improve the visualization of any graphical data, every one want to have the object should be in 3 dimensions. In place of having the video of the particular object, if we have the 2 dimensional images of that object, then question arise- how to get the 3 dimension object from the available 2 dimension images? In literature, this problem is addressed by different solution methodologies and techniques. Prominent from them are: Perspective geometric model; Stereoscopic visualization; Cross eye visualization; Depth map generation; and Using 2 dimension drawings i.e. isometric views. This paper addresses the above mentioned problem with actual method for conversion of object from 2dimensional images of an object to 3dimesinal object using shock graph method. In this paper, we are mentioning the actual method for conversion. Paper ends with the discussion of the status of our work where we have been reached so far. At the end we can say that still, 3 dimension object formation is the key research area where the researchers are having much more scope to contribute.

    The novel object recognition, or novel-object preference (NOP) test is employed to assess recognition memory in a variety of organisms. The subject is exposed to two identical objects, then after a delay, it is placed back in the original environment containing one of the original objects and a novel object. If the subject spends more time exploring one object, this can be interpreted as memory retention. To date, this test has not been fully explored in zebrafish (Danio rerio). Zebrafish possess recognition memory for simple 2- and 3-dimensional geometrical shapes, yet it is unknown if this translates to complex 3-dimensional objects. In this study we evaluated recognition memory in zebrafish using complex objects of different sizes. Contrary to rodents, zebrafish preferentially explored familiar over novel objects. Familiarity preference disappeared after delays of 5 mins. Leopard danios, another strain of D. rerio, also preferred the familiar object after a 1 min delay. Object preference could be re-established in zebra danios by administration of nicotine tartrate salt (50mg/L) prior to stimuli presentation, suggesting a memory-enhancing effect of nicotine. Additionally, exploration biases were present only when the objects were of intermediate size (2 × 5 cm). Our results demonstrate zebra and leopard danios have recognition memory, and that low nicotine doses can improve this memory type in zebra danios. However, exploration biases, from which memory is inferred, depend on object size. These findings suggest zebrafish ecology might influence object preference, as zebrafish neophobia could reflect natural anti-predatory behaviour.

  8. Object-Based Attention Guided by An Invisible Object

    Directory of Open Access Journals (Sweden)

    Xilin Zhang

    2011-05-01

    Full Text Available Many studies have demonstrated that attention can be object based. One line of evidence supporting object-based attention showed that observers respond to a target faster when the target and cue are in the same object than when they are in different objects, which is called the same-object advantage. By adopting the double-rectangle cuing paradigm (Egly, Driver, & Rafal, 1994, we tested whether this advantage can occur with invisible rectangles. The original paradigm was slightly modified. Rectangles had a low luminance level against a dark background and were presented for only 10 ms, along with a cue or a target. These two characteristics rendered the rectangles invisible to subjects, as confirmed by a forced-choice test. We found a conventional object-based attention effect even when the rectangles were invisible. We also found that the object-based attention was dependent on the orientation of the rectangles presented along with the target, consistent with the finding by Ho and Yeh (2009. These results suggest that object based attention can be guided by an invisible object in an automatic way, with a minimal influence from the high level top-down control.

    Besides economics and controllability, waste minimization has now become an obje ctive in designing chemical processes, and usually leads to high costs of invest ment and operation. An attempt was made to minimize waste discharged from chemic al reaction processes during the design and modification process while the opera tion conditions were also optimized to meet the requirements of technology and e conomics. Multiobjectives decision nonlinear programming (NLP) was employed to o ptimize the operation conditions of a chemical reaction process and reduce waste . A modeling language package-SPEEDUP was used to simulate the process. This p aper presents a case study of the benzene production process. The flowsheet factors affecting the economics and waste generation were examined. Constraints were imposed to reduce the number of objectives and carry out optimal calculations e asily. After comparisons of all possible solutions, best-compromise approach wa s applied to meet technological requirements and minimize waste.

    2011-12-01

    Full Text Available The field of numerical cognition represents an interesting case for action-based theories of cognition, since number is a special kind of abstract concept. Several studies have shown that within the parietal lobes adjacent neural regions code numerical magnitude and grasping-related information. This anatomical proximity between brain areas involved in number and sensorimotor processes may account for interactions between numerical magnitude and action. In particular, recent studies has demonstrated a causal role of action perception on numerical magnitude processing. If objects are represented in terms of actions (affordances, the causal role of action on number processing should extend to the case of objects affordances. This study investigates the relationship between numbers and objects affordances in two experiments, without (Experiment 1 or with (Experiment 2 a motor action execution (i.e., participants were asked to hold an object in their hands during the task. The task consisted in repeating aloud the odd or even digit within a pair depending on the type of the preceding or following object. Order of presentation (object-number vs. number-object, object type (graspable vs. ungraspable, object size (small vs. large, and Numerical magnitude (small vs. large were manipulated for each experiment. Experiment 1 showed a facilitation – in terms of quicker responses - for graspable over ungraspable objects preceded by numbers, and an effect of numerical magnitude after the presentation of graspable objects. Experiment 2 demonstrated that the action execution enhanced overall the sensitivity to numerical magnitude, however interfering with the effects of objects affordances on number processing. Overall, these findings demonstrate that numbers and graspable objects communicate with each other, supporting the view that abstract concepts may be grounded in motor experience.

    2007-01-01

    The development of functional genomics including transcriptomics, proteomics and metabolomics allow us to monitor a large number of key cellular pathways simultaneously. Several technology-specific data models have been introduced for the representation of functional genomics experimental data, including the MicroArray Gene Expression-Object Model (MAGE-OM), the Proteomics Experiment Data Repository (PEDRo), and the Tissue MicroArray-Object Model (TMA-OM). Despite the increasing number of cancer studies using multiple functional genomics technologies, there is still no integrated data model for multiple functional genomics experimental and clinical data. We propose an object-oriented data model for cancer genomics research, Cancer Genomics Object Model (CaGe-OM). We reference four data models: Functional Genomic-Object Model, MAGE-OM, TMAOM and PEDRo. The clinical and histopathological information models are created by analyzing cancer management workflow and referencing the College of American Pathology Cancer Protocols and National Cancer Institute Common Data Elements. The CaGe-OM provides a comprehensive data model for integrated storage and analysis of clinical and multiple functional genomics data.

  16. Channels as Objects in Concurrent Object-Oriented Programming

    Directory of Open Access Journals (Sweden)

    Joana Campos

    2011-10-01

    Full Text Available There is often a sort of a protocol associated to each class, stating when and how certain methods should be called. Given that this protocol is, if at all, described in the documentation accompanying the class, current mainstream object-oriented languages cannot provide for the verification of client code adherence against the sought class behaviour. We have defined a class-based concurrent object-oriented language that formalises such protocols in the form of usage types. Usage types are attached to class definitions, allowing for the specification of (1 the available methods, (2 the tests clients must perform on the result of methods, and (3 the object status - linear or shared - all of which depend on the object's state. Our work extends the recent approach on modular session types by eliminating channel operations, and defining the method call as the single communication primitive in both sequential and concurrent settings. In contrast to previous works, we define a single category for objects, instead of distinct categories for linear and for shared objects, and let linear objects evolve into shared ones. We introduce a standard sync qualifier to prevent thread interference in certain operations on shared objects. We formalise the language syntax, the operational semantics, and a type system that enforces by static typing that methods are called only when available, and by a single client if so specified in the usage type. We illustrate the language via a complete example.

    2006-01-01

    Recently, forensic investigators1 have started using diagnostic radiology devices (MRI, CT) to acquire image data from cadavers. This new technology, called the virtual autopsy, has the potential to provide a low cost, non-invasive alternative or supplement to conventional autopsies. New image processing techniques are being developed to highlight forensically relevant information in the images. One such technique is the detection and characterization of metal objects embedded in the cadaver. Analysis of this information across a population with similar causes of death can lead to developing improved safety and protection devices with a corresponding reduction in deaths.

    Full Text Available Traditional mind-body identity theories maintain that consciousness is identical with neural activity. Consider an alternative identity theory – namely, a mind-object identity theory of consciousness (OBJECTBOUND. I suggest to take into consideration whether one’s consciousness might be identical with the external object. The hypothesis is that, when I perceive a yellow banana, the thing that is one and the same with my consciousness of the yellow banana is the very yellow banana one can grab and eat, rather than the neural processes triggered by the banana. The bottom line is that one’s conscious experience of an object is the object one experiences. First, I outline the main hypothesis and the relation between mind, body, and object. Eventually, I address a series of traditional obstacles such as hallucinations, illusions, and commonsensical assumptions.

    2015-03-01

    Full Text Available In computer vision application, moving object detection is the key technology for intelligent video monitoring system. Performance of an automated visual surveillance system considerably depends on its ability to detect moving objects in thermodynamic environment. A subsequent action, such as tracking, analyzing the motion or identifying objects, requires an accurate extraction of the foreground objects, making moving object detection a crucial part of the system. The aim of this paper is to detect real moving objects from un-stationary background regions (such as branches and leafs of a tree or a flag waving in the wind, limiting false negatives (objects pixels that are not detected as much as possible. In addition, it is assumed that the models of the target objects and their motion are unknown, so as to achieve maximum application independence (i.e. algorithm works under the non-prior training.

    Turbulence of a windtunnel flow is stirred using objects that have a fractal structure. The strong turbulent wakes resulting from three such objects which have different fractal dimensions are probed using multiprobe hot-wire anemometry in various configurations. Statistical turbulent quantities are studied within inertial and dissipative range scales in an attempt to relate changes in their self-similar behavior to the scaling of the fractal objects.

  6. Objects in Films: analyzing signs

    Directory of Open Access Journals (Sweden)

    GAMBARATO, Renira Rampazzo

    2009-12-01

    Full Text Available The focus of this essay is the analysis of daily objects as signs in films. Objects from everyday life acquire several functions in films: they can be solely used as scene objects or to support a particular film style. Other objects are specially chosen to translate a character’s interior state of mind or the filmmaker’s aesthetical or ethical commitment to narrative concepts. In order to understand such functions and commitments, we developed a methodology for film analysis which focuses on the objects. Object interpretation, as the starting point of film analysis, is not a new approach. For instance, French film critic André Bazin proposed that use of object interpretation in the 1950s. Similarly, German film theorist Siegfried Kracauer stated it in the 1960s. However, there is currently no existing analytical model to use when engaging in object interpretation in film. This methodology searches for the most representative objects in films which involves both quantitative and qualitative analysis; we consider the number of times each object appears in a film (quantitative analysis as well as the context of their appearance, i.e. the type of shot used and how that creates either a larger or smaller relevance and/or expressiveness (qualitative analysis. In addition to the criteria of relevance and expressiveness, we also analyze the functionality of an object by exploring details and specifying the role various objects play in films. This research was developed at Concordia University, Montreal, Canada and was supported by the Foreign Affairs and International Trade, Canada (DFAIT.

    This article considers how people judge the identity of objects (e.g., how people decide that a description of an object at one time, t-sub-0, belongs to the same object as a description of it at another time, t-sub-1). The authors propose a causal continuer model for these judgments, based on an earlier theory by Nozick (1981). According to this…

  8. Incremental Visualizer for Visible Objects

    DEFF Research Database (Denmark)

    Bukauskas, Linas; Bøhlen, Michael Hanspeter

    This paper discusses the integration of database back-end and visualizer front-end into a one tightly coupled system. The main aim which we achieve is to reduce the data pipeline from database to visualization by using incremental data extraction of visible objects in a fly-through scenarios. We...... also argue that passing only relevant data from the database will substantially reduce the overall load of the visualization system. We propose the system Incremental Visualizer for Visible Objects (IVVO) which considers visible objects and enables incremental visualization along the observer movement...... visibility ranges and show that considering visibility ranges is crucial when considering incremental visible object extraction....

  9. Minimum Delay Moving Object Detection

    KAUST Repository

    Lao, Dong

    2017-05-14

    This thesis presents a general framework and method for detection of an object in a video based on apparent motion. The object moves, at some unknown time, differently than the “background” motion, which can be induced from camera motion. The goal of proposed method is to detect and segment the object as soon it moves in an online manner. Since motion estimation can be unreliable between frames, more than two frames are needed to reliably detect the object. Observing more frames before declaring a detection may lead to a more accurate detection and segmentation, since more motion may be observed leading to a stronger motion cue. However, this leads to greater delay. The proposed method is designed to detect the object(s) with minimum delay, i.e., frames after the object moves, constraining the false alarms, defined as declarations of detection before the object moves or incorrect or inaccurate segmentation at the detection time. Experiments on a new extensive dataset for moving object detection show that our method achieves less delay for all false alarm constraints than existing state-of-the-art.

  10. Converting a carbon preform object to a silicon carbide object

    A process for converting in depth a carbon or graphite preform object to a silicon carbide object, silicon carbide/silicon object, silicon carbide/carbon-core object, or a silicon carbide/silicon/carbon-core object, by contacting it with silicon liquid and vapor over various lengths of contact time in a reaction chamber. In the process, a stream comprised of a silicon-containing precursor material in gaseous phase below the decomposition temperature of said gas and a coreactant, carrier or diluent gas such as hydrogen is passed through a hole within a high emissivity, thin, insulating septum into the reaction chamber above the melting point of silicon. The thin septum has one face below the decomposition temperature of the gas and an opposite face exposed to the reaction chamber. Thus, the precursor gas is decomposed directly to silicon in the reaction chamber. Any stream of decomposition gas and any unreacted precursor gas from the reaction chamber is removed. A carbon or graphite preform object placed in the reaction chamber is contacted with the silicon. The carbon or graphite preform object is recovered from the reactor chamber after it has been converted to a desired silicon carbide, silicon and carbon composition.

  11. Quantum field theories of extended objects

    Friedan, Daniel

    2016-01-01

    First steps are taken in a project to construct a general class of conformal and perhaps, eventually, non-conformal quantum field theories of (n-1)-dimensional extended objects in a d=2n dimensional conformal space-time manifold M. The fields live on the spaces E of relative integral (n-1)-cycles in M -- the integral (n-1)-currents of given boundary. Each E is a complete metric space geometrically analogous to a Riemann surface $\\Sigma$. For example, if $M=S^d$, $\\Sigma = S^2$. The quantum fields on E are to be mapped to observables in a 2d CFT on $\\Sigma$. The correlation functions on E are to be given by the 2d correlation functions on $\\Sigma$. The goal is to construct a CFT of extended objects in d=2n dimensions for every 2d CFT, and eventually a non-conformal QFT of extended objects for every non-conformal 2d QFT, so that all the technology of 2d QFT can be applied to the construction and analysis of quantum field theories of extended objects. The project depends crucially on settling some mathematical q...

    A higher spectral resolution is the main direction of developing remote sensing technology, and it is quite important to set up the digital ground object reflectance spectral database library, one of fundamental research fields in remote sensing application. Remote sensing application has been increasingly relying on ground object spectral characteristics, and quantitative analysis has been developed to a new stage. The present article summarized and systematically introduced the research status quo and development trend of digital ground object reflectance spectral libraries at home and in the world in recent years. Introducing the spectral libraries has been established, including desertification spectral database library, plants spectral database library, geological spectral database library, soil spectral database library, minerals spectral database library, cloud spectral database library, snow spectral database library, the atmosphere spectral database library, rocks spectral database library, water spectral database library, meteorites spectral database library, moon rock spectral database library, and man-made materials spectral database library, mixture spectral database library, volatile compounds spectral database library, and liquids spectral database library. In the process of establishing spectral database libraries, there have been some problems, such as the lack of uniform national spectral database standard and uniform standards for the ground object features as well as the comparability between different databases. In addition, data sharing mechanism can not be carried out, etc. This article also put forward some suggestions on those problems.

  13. Object Based Middleware for Grid Computing

    Full Text Available Problem statement: “Grid” computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment. Essentially, middleware is a distributed software layer, which abstracts over the complexity and heterogeneity of the underlying distributed environment with its multitude of network technologies, machine architectures, operating systems and programming languages. Approach: This study brought out the development of supportive middleware to manage resources and distributed workload across multiple administrative boundaries is of central importance to Grid computing. Active middleware services that perform look-up, scheduling and staging are being developed that allow users to identify and utilize appropriate resources that provide sustainable system and user-level qualities of service. Results: Different middleware platforms support different programming models. Perhaps the most popular model is object-based middleware in which applications are structured into objects that interact via location transparent method invocation. Conclusion: The Object Management Group’s CORBA platform offer an Interface Definition Language (IDL which is used to abstract over the fact that objects can be implemented in any suitable programming language, an object request broker which is responsible for transparently directing method invocations to the appropriate target object and a set of services such as naming, time, transactions, replication which further enhance the programming environment.

  19. Zero-Copy Objects System

    Science.gov (United States)

    Burleigh, Scott C.

    2011-01-01

    Zero-Copy Objects System software enables application data to be encapsulated in layers of communication protocol without being copied. Indirect referencing enables application source data, either in memory or in a file, to be encapsulated in place within an unlimited number of protocol headers and/or trailers. Zero-copy objects (ZCOs) are abstract data access representations designed to minimize I/O (input/output) in the encapsulation of application source data within one or more layers of communication protocol structure. They are constructed within the heap space of a Simple Data Recorder (SDR) data store to which all participating layers of the stack must have access. Each ZCO contains general information enabling access to the core source data object (an item of application data), together with (a) a linked list of zero or more specific extents that reference portions of this source data object, and (b) linked lists of protocol header and trailer capsules. The concatenation of the headers (in ascending stack sequence), the source data object extents, and the trailers (in descending stack sequence) constitute the transmitted data object constructed from the ZCO. This scheme enables a source data object to be encapsulated in a succession of protocol layers without ever having to be copied from a buffer at one layer of the protocol stack to an encapsulating buffer at a lower layer of the stack. For large source data objects, the savings in copy time and reduction in memory consumption may be considerable.
