  12. Drugs, Devices & Discovery: Using Fee-Shifting to Resolve the Twombly/Iqbal Problem for Parallel Claims Under the FDCA.

    PubMed

    Norris, Cameron T

    2015-01-01

    The Supreme Court's decisions in Twombly and Iqbal ushered in a new federal pleading standard, requiring plaintiffs to state a "plausible" claim to relief before they can access discovery. Plausibility pleading, however, presents a unique burden for plaintiffs who have been injured by a Class III medical device. In Riegel, the Supreme Court held that state-law claims against device manufacturers are preempted unless they "parallel" federal requirements. However, the relevant federal requirements are located in the manufacturer's premarket approval agreement, which is confidential. Thus, it is nearly impossible for plaintiffs to allege a plausible claim against a Class III device manufacturer because they do not know what to plead in the first place. The Seventh Circuit tried to remedy this Catch-22 by lowering the pleading standards for parallel claims. However, its approach misapplies Twombly and Iqbal and overburdens device manufacturers. Instead of tinkering with pleading standards, this paper advocates a different approach. Congress should create a one-way fee-shifting mechanism that allows plaintiffs to access premarket approval agreements if they agree to pay the defendant's discovery fees (should their claim prove unsuccessful). Fee-shifting is a middle-ground approach that would better compensate plaintiffs without overdeterring device manufacturers. PMID:26292477

    Ladies and Gentlemen, it is my great honor and pleasure to present an opening address of the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3). On the behalf of the organizing committee, I certainly welcome all your visits to KGU Kannai Media Center belonging to Kanto Gakuin University, and stay in Yokohama. In particular, to whom come from abroad more than 17 countries, I would appreciate your participations after long long trips from your homeland to Yokohama. The first international workshop on "State of the Art in Nuclear Cluster Physics", called SOTANCP, was held in Strasbourg, France, in 2008, and the second one was held in Brussels, Belgium, in 2010. Then the third workshop is now held in Yokohama. In this period, we had the traditional 10th cluster conference in Debrecen, Hungary, in 2012. Thus we have the traditional cluster conference and SOTANCP, one after another, every two years. This obviously shows our field of nuclear cluster physics is very active and flourishing. It is for the first time in about 10 years to hold the international workshop on nuclear cluster physics in Japan, because the last cluster conference held in Japan was in Nara in 2003, about 10 years ago. The president in Nara conference was Prof. K. Ikeda, and the chairpersons were Prof. H. Horiuchi and Prof. I. Tanihata. I think, quite a lot of persons in this room had participated at the Nara conference. Since then, about ten years passed. So, this workshop has profound significance for our Japanese colleagues. The subjects of this workshop are to discuss "the state of the art in nuclear cluster physics" and also discuss the prospect of this field. In a couple of years, we saw significant progresses of this field both in theory and in experiment, which have brought better and new understandings on the clustering aspects in stable and unstable nuclei. I think, the concept of clustering has been more important than ever. This is true also in the related fields such as nuclear astrophysics, hypernuclear physics, hadron physics, and condensate matter physics so on. In fact, in this workshop, we also discuss the clustering aspects in the related fields. Thus, I expect in this workshop we can grasp the present status of the nuclear cluster physics and demonstrate its perspective in near future. This workshop is sponsored by several institutes and organizations. In particular, I would express our thanks for financial supports to Research Center for Nuclear Physics (RCNP), Osaka University, Center for Nuclear Study (CNS), University of Tokyo, Joint Institute for Computational Fundamental Science (JICFuS), and RIKEN Nishina Center for Accelerator- Based Science. They are cohosting this workshop. I would like also to appreciate my University, Kanto Gakuin University, who offers this nice place for one week and helps us to hold this workshop smoothly and conveniently. Today, the president of my University, Prof. Kuku, is here to present a welcome address. Thank you very much. Finally, with many of the participants leading this field both in theory and in experiment, we wish this workshop offers an opportunity to simulate communications not only during the workshop but also in the future. In addition, we hope you enjoy exploring city of Yokohama and the area around, as well as scientific discussions. Thank you very much for your attention.

    Envia, Edmane

    2012-01-01

    Owing to their inherent fuel efficiency, there is renewed interest in developing open rotor propulsion systems that are both efficient and quiet. The major contributor to the overall noise of an open rotor system is the propulsor noise, which is produced as a result of the interaction of the airstream with the counter-rotating blades. As such, robust aeroacoustic prediction methods are an essential ingredient in any approach to designing low-noise open rotor systems. To that end, an effort has been underway at NASA to assess current open rotor noise prediction tools and develop new capabilities. Under this effort, high-fidelity aerodynamic simulations of a benchmark open rotor blade set were carried out and used to make noise predictions via existing NASA open rotor noise prediction codes. The results have been compared with the aerodynamic and acoustic data that were acquired for this benchmark open rotor blade set. The emphasis of this paper is on providing a summary of recent results from a NASA Glenn effort to validate an in-house open noise prediction code called LINPROP which is based on a high-blade-count asymptotic approximation to the Ffowcs-Williams Hawkings Equation. The results suggest that while predicting the absolute levels may be difficult, the noise trends are reasonably well predicted by this approach.

    Price, Erika; Ottati, Victor; Wilson, Chase; Kim, Soyeon

    2015-11-01

    The present research conceptualizes open-minded cognition as a cognitive style that influences how individuals select and process information. An open-minded cognitive style is marked by willingness to consider a variety of intellectual perspectives, values, opinions, or beliefs-even those that contradict the individual's opinion. An individual's level of cognitive openness is expected to vary across domains (such as politics and religion). Four studies develop and validate a novel measure of open-minded cognition, as well as two domain-specific measures of religious and political open-minded cognition. Exploratory and confirmatory factor analysis (controlling for acquiescence bias) are used to develop the scales in Studies 1 to 3. Study 4 demonstrates that these scales possess convergent and discriminant validity. Study 5 demonstrates the scale's unique predictive validity using the outcome of Empathic Concern (Davis, 1980). Study 6 demonstrates the scale's unique predictive validity using the outcomes of warmth toward racial, religious, and sexual minorities. PMID:26315581

    A new type of thermodynamic device combining a thermodynamic cycle with the externally applied steady flow of an open thermodynamic process is discussed and experimentally demonstrated. The gas flowing through this device can be heated or cooled in a series of semi-open cyclic steps. The combination of open and cyclic flows makes possible the elimination of some or all of the heat exchangers (with their associated invversibility). Heat is directly exchanged with the process fluid as it flows through the device when operating as a refrigerator, producing a staging effect that tends to increase First Law thermodynamic efficiency. An open-flow thermoacoustic refrigerator was built to demonstrate this concept, Several approaches are presented that describe the physical characteristics of this device. Tests have been conducted on this refrigerator with good agreement with a proposed theory.

  14. OpenTopography

    NASA Astrophysics Data System (ADS)

    Baru, C.; Arrowsmith, R.; Crosby, C.; Nandigam, V.; Phan, M.; Cowart, C.

    2012-04-01

    OpenTopography is a cyberinfrastructure-based facility for online access to high-resolution topography and tools. The project is an outcome of the Geosciences Network (GEON) project, which was a research project funded several years ago in the US to investigate the use of cyberinfrastructure to support research and education in the geosciences. OpenTopography provides online access to large LiDAR point cloud datasets along with services for processing these data. Users are able to generate custom DEMs by invoking DEM services provided by OpenTopography with custom parameter values. Users can track the progress of their jobs, and a private myOpenTopo area retains job information and job outputs. Data available at OpenTopography are provided by a variety of data acquisition groups under joint agreements and memoranda of understanding (MoU). These include national facilities such as the National Center for Airborne Lidar Mapping, as well as local, state, and federal agencies. OpenTopography is also being designed as a hub for high-resolution topography resources. Datasets and services available at other locations can also be registered here, providing a "one-stop shop" for such information. We will describe the OpenTopography system architecture and its current set of features, including the service-oriented architecture, a job-tracking database, and social networking features. We will also describe several design and development activities underway to archive and publish datasets using digital object identifiers (DOIs); create a more flexible and scalable high-performance environment for processing of large datasets; extend support for satellite-based and terrestrial lidar as well as synthetic aperture radar (SAR) data; and create a "pluggable" infrastructure for third-party services. OpenTopography has successfully created a facility for sharing lidar data. In the next phase, we are developing a facility that will also enable equally easy and successful sharing of services related to these data.

  16. The open boundary equation

    NASA Astrophysics Data System (ADS)

    Diederen, D.; Savenije, H. H. G.; Toffolon, M.

    2015-06-01

    We present a new equation describing the hydrodynamics in infinitely long tidal channels (i.e., no reflection) under the influence of oceanic forcing. The proposed equation is a simple relationship between partial derivatives of water level and velocity. It is formally derived for a progressive wave in a frictionless, prismatic, tidal channel with a horizontal bed. Assessment of a large number of numerical simulations, where an open boundary condition is posed at a certain distance landward, suggests that it can also be considered accurate in the more natural case of converging estuaries with nonlinear friction and a bed slope. The equation follows from the open boundary condition and is therefore a part of the problem formulation for an infinite tidal channel. This finding provides a practical tool for evaluating tidal wave dynamics, by reconstructing the temporal variation of the velocity based on local observations of the water level, providing a fully local open boundary condition and allowing for local friction calibration.

    Background The Blue Obelisk movement was established in 2005 as a response to the lack of Open Data, Open Standards and Open Source (ODOSOS) in chemistry. It aims to make it easier to carry out chemistry research by promoting interoperability between chemistry software, encouraging cooperation between Open Source developers, and developing community resources and Open Standards. Results This contribution looks back on the work carried out by the Blue Obelisk in the past 5 years and surveys progress and remaining challenges in the areas of Open Data, Open Standards, and Open Source in chemistry. Conclusions We show that the Blue Obelisk has been very successful in bringing together researchers and developers with common interests in ODOSOS, leading to development of many useful resources freely available to the chemistry community.

    In contrast to closed Achilles tendon ruptures, open injuries are rarely reported in the literature. This paper provides information about open Achilles tendon wounds that are eventually seen in the Middle East. The reporting unit, Hamad Medical Corporation, is one of the biggest trauma centers in the Gulf area and the major health provider in Qatar. This is a retrospective study including patients admitted and operated for open Achilles tendon injuries between January 2011 and December 2013. Two hundred and five cases of open Achilles tendon lacerations were operated in Hamad General Hospital in this period. Forty-eight cases showed partial injuries, and the remaining are complete tendons cut. In the same period, fifty-one closed ruptured Achilles tendons were operated in the same trauma unit. In the majority of cases, the open injury resulted from a slip in the floor-leveled traditional toilette seats. Local damage to the toilette seats resulted in sharp edges causing the laceration of the heel if the patient was slipping over the wet floor. This occurrence is the cause in the vast majority of the cases. Wounds were located 1-5 cm proximal to tendon insertion. Standard treatment principles were applied. This included thorough irrigation in the emergency room, intravenous antibiotics, surgical debridement and primary repair within 24 h. Patients were kept in the hospital 1-7 days for intravenous antibiotics and possible dressing changes. Postoperatively below knee slabs were applied in the majority of patients and were kept for about 4 weeks followed by gradual weight bearing and range of motion exercises. Outpatients follow up in 1-2 weeks. Further follow-up visits at around 2-, 4-, 8- and 12-week intervals until complete wound healing and satisfactory rehabilitation outcome. Sixteen cases needed a second procedure. A high incidence of Achilles tendon open injuries is reported. This seems to be related to partially damaged floor-level toilettes in the typical Middle-East lavatory. The surgical treatment resulted in excellent outcome in the vast majority of the cases. Low incidence of complications resulted despite dramatic injury pattern. PMID:25337957

  9. Open architecture CNC system

    Tal, J.; Lopez, A.; Edwards, J.M.

    1995-04-01

    In this paper, an alternative solution to the traditional CNC machine tool controller has been introduced. Software and hardware modules have been described and their incorporation in a CNC control system has been outlined. This type of CNC machine tool controller demonstrates that technology is accessible and can be readily implemented into an open architecture machine tool controller. Benefit to the user is greater controller flexibility, while being economically achievable. PC based, motion as well as non-motion features will provide flexibility through a Windows environment. Up-grading this type of controller system through software revisions will keep the machine tool in a competitive state with minimal effort. Software and hardware modules are mass produced permitting competitive procurement and incorporation. Open architecture CNC systems provide diagnostics thus enhancing maintainability, and machine tool up-time. A major concern of traditional CNC systems has been operator training time. Training time can be greatly minimized by making use of Windows environment features.

  10. Plasma opening switch

    Savage, Mark E. (Albuquerque, NM); Mendel, Jr., Clifford W. (Albuquerque, NM)

    2001-01-01

    A command triggered plasma opening switch assembly using an amplification stage. The assembly surrounds a coaxial transmission line and has a main plasma opening switch (POS) close to the load and a trigger POS upstream from the main POS. The trigger POS establishes two different current pathways through the assembly depended on whether it has received a trigger current pulse. The initial pathway has both POS's with plasma between their anodes and cathodes to form a short across the transmission line and isolating the load. The final current pathway is formed when the trigger POS receives a trigger current pulse which energizes its fast coil to push the conductive plasma out from between its anode and cathode, allowing the main transmission line current to pass to the fast coil of the main POS, thus pushing its plasma out the way so as to establish a direct current pathway to the load.

    In a report released last week the National Academy of Sciences' Panel on Scientific Communication and National Security concluded that the ‘limited and uncertain benefits’ of controls on the dissemination of scientific and technological research are ‘outweighed by the importance of scientific progress, which open communication accelerates, to the overall welfare of the nation.’ The 18-member panel, chaired by Dale R. Corson, president emeritus of Cornell University, was created last spring (Eos, April 20, 1982, p. 241) to examine the delicate balance between open dissemination of scientific and technical information and the U.S. government's desire to protect scientific and technological achievements from being translated into military advantages for our political adversaries.The panel dealt almost exclusively with the relationship between the United States and the Soviet Union but noted that there are ‘clear problems in scientific communication and national security involving Third World countries.’ Further study of this matter is necessary.

  13. Open boundary molecular dynamics

    NASA Astrophysics Data System (ADS)

    Delgado-Buscalioni, R.; Sabli?, J.; Praprotnik, M.

    2015-09-01

    This contribution analyzes several strategies and combination of methodologies to perform molecular dynamic simulations in open systems. Here, the term open indicates that the total system has boundaries where transfer of mass, momentum and energy can take place. This formalism, which we call Open Boundary Molecular Dynamics (OBMD), can act as interface of different schemes, such as Adaptive Resolution Scheme (AdResS) and Hybrid continuum-particle dynamics to link atomistic, coarse-grained (CG) and continuum (Eulerian) fluid dynamics in the general framework of fluctuating Navier-Stokes equations. The core domain of the simulation box is solved using all-atom descriptions. The CG layer introduced using AdResS is located at the outer part of the open box to make feasible the insertion of large molecules into the system. Communications between the molecular system and the outer world are carried out in the outer layers, called buffers. These coupling preserve momentum and mass conservation laws and can thus be linked with Eulerian hydro- dynamic solvers. In its simpler form, OBMD allows, however, to impose a local pressure tensor and a heat flux across the system's boundaries. For a one component molecular system, the external normal pressure and temperature determine the external chemical potential and thus the independent parameters of a grand-canonical ensemble simulation. Extended ensembles under non-equilibrium stationary states can also be simulated as well as time dependent forcings (e.g. oscillatory rheology). To illustrate the robustness of the combined OBMD-AdResS method, we present simulations of star-polymer melts at equilibrium and in sheared flow.

System software is provided in the form of ConvexOS, a POSIX compliant derivative of 4.3BSD UNIX. Storage applications include products such as UNITREE and EMASS. With the DS Series of storage systems, Convex has developed a set of products which provide open system solutions for storage management applications. The systems are highly modular, assembled from off the shelf components with industry standard interfaces. The C Series system architecture provides a stable base, with the performance and reliability of a general purpose platform. This combination of a proven system architecture with a variety of choices in peripherals and application software allows wide flexibility in configurations, and delivers the benefits of open systems to the mass storage world.

  17. Bispectrum from open inflation

    SciTech Connect

    Sugimura, Kazuyuki; Komatsu, Eiichiro E-mail: komatsu@mpa-garching.mpg.de

    2013-11-01

    We calculate the bispectrum of primordial curvature perturbations, ?, generated during ''open inflation.'' Inflation occurs inside a bubble nucleated via quantum tunneling from the background false vacuum state. Our universe lives inside the bubble, which can be described as a Friedmann-Lema?tre-Robertson-Walker (FLRW) universe with negative spatial curvature, undergoing slow-roll inflation. We pay special attention to the issue of an initial state for quantum fluctuations. A ''vacuum state'' defined by a positive-frequency mode in de Sitter space charted by open coordinates is different from the Euclidean vacuum (which is equivalent to the so-called ''Bunch-Davies vacuum'' defined by a positive-frequency mode in de Sitter space charted by flat coordinates). Quantum tunneling (bubble nucleation) then modifies the initial state away from the original Euclidean vacuum. While most of the previous study on modifications of the initial quantum state introduces, by hand, an initial time at which the quantum state is modified as well as the form of the modification, an effective initial time naturally emerges and the form is fixed by quantum tunneling in open inflation models. Therefore, open inflation enables a self-consistent computation of the effect of a modified initial state on the bispectrum. We find a term which goes as (?{sub k{sub 1}}?{sub k{sub 2}}?{sub k{sub 3}})?1/k{sub 1}{sup 2}k{sub 3}{sup 4} in the so-called squeezed configurations, k{sub 3} << k{sub 1} ? k{sub 2}, in agreement with the previous study on modifications of the initial state. The bispectrum in the exact folded limit, e.g., k{sub 1} = k{sub 2}+k{sub 3}, is also enhanced and remains finite. However, these terms are exponentially suppressed when the wavelength of ? is smaller than the curvature radius of the universe. The leading-order bispectrum is equal to the usual one from single-field slow-roll inflation; the terms specific for open inflation arise only in the sub-leading order when the wavelength of ? is smaller than the curvature radius.

These fixes will then by incorporated by Sun into their Sun Access Manager product, which is used by various DOE/NNSA plants and labs. Having Sun maintain these changes will relieve SNL and DOE from the cost of maintaining the changes themselves.

  2. Scarring in open quantum systems.

    Wisniacki, Diego; Carlo, Gabriel G

    2008-04-01

    We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable short periodic orbits in a similar way as their closed counterparts. The structure of eigenfunctions around these classical objects is not destroyed by the opening. This is exposed in a paradigmatic system of quantum chaos, the cat map. PMID:18517679

    Arsenic contamination of groundwater resources threatens the health of millions of people worldwide, particularly in the densely populated river deltas of Southeast Asia. Arsenic causes health concerns due to its significant toxicity and worldwide presence in portable water. The major sources of arsenic pollution may be natural process such as dissolution of arsenic containing minerals and anthropogenic activities. Lahore is groundwater dependent city, arsenic contamination is a major issue of portable water and has recently been most environmental health management issue especially in the plain region, where population density is very high. GIS was used in this study for visualizing distribution of arsenic groundwater concentration through geostatistics analysis technique, and exposure risk zones for two years (2010 and 2012). Town's data was compared and concentration variation evaluated. ANOVA test was also applied to compare concentration between cities and years. Arsenic concentrations widely range 7.3-67.8 and 5.2-69.3 ?g L-1 in 2010 and 2012, respectively. Over 71% area is represented arsenic concentration range from 20 to 30 ?g L-1 in both analyzed years. However, in 2012 arsenic concentration over 40 ?g L-1 has covered 7.6% area of Data Gunjbuksh and 8.1% of Ravi Town, while over 90% area of Allama Iqbal, Aziz Bhatti and Samanabad Town contain arsenic concentration between 20-30 ?g L-1. ANOVA test depicts concentration probability less than 0.05, while differences were detected among towns. In light of current results, it needs urgent step to ensure groundwater protection and preservation for future.

  6. Social consequences of experiential openness.

    PubMed

    McCrae, R R

    1996-11-01

    Openness to Experience is one of the 5 broad factors that subsume most personality traits. Openness is usually considered an intrapsychic dimension, defined in terms of characteristics of consciousness. However, different ways of approaching and processing experience lead to different value systems that exercise a profound effect on social interactions. In this article, the author reviews the effects of Openness versus Closedness in cultural innovation, political ideology, social attitudes, marital choice, and interpersonal relations. The construct of Openness and its measures could profitably be incorporated into research conducted by social psychologists, sociologists, political scientists, anthropologists, and historians.

    A reusable fast opening switch for transferring energy, in the form of a high power pulse, from an electromagnetic storage device such as an inductor into a load. The switch is efficient, compact, fast and reusable. The switch comprises a ferromagnetic semiconductor which undergoes a fast transition between conductive and metallic states at a critical temperature and which undergoes the transition without a phase change in its crystal structure. A semiconductor such as europium rich europhous oxide, which undergoes a conductor to insulator transition when it is joule heated from its conductor state, can be used to form the switch.

    High-performance buildings require an integrated design approach for all systems to work together optimally; systems integration needs to be incorporated in the earliest stages of design for efforts to be cost and energy-use effective. Building designers need a full-featured software framework to support rigorous, multidisciplinary building simulation. An open source framework - the OpenStudio Software Development Kit (SDK) - is being developed to address this need. In this paper, we discuss the needs that drive OpenStudio's system architecture and goals, provide a development status report (the SDK is currently in alpha release), and present a brief case study that illustrates its utility and flexibility.

    Tubular solenoids have been widely used without any change since an electrical wire was discovered to create magnetic fields by Hans Christian Oersted in 1820 and thereby the wire was first coiled as a helix into a solenoid coil by William Sturgeon in 1823 and was improved by Joseph Henry in 1829 [see http://www.myetymology.com/encyclopedia/History_of_the_electricity.html; J. M. D. Coey, Magnetism and Magnetic Materials (Cambridge University Press, New York, 2010); and F. Winterberg, Plasma Phys. 8, 541553 (1996)]. A magnetic control method of C-shaped carrying-current wire is proposed, and thereby a new opening electromagnetic transducer evidently differing from the traditional tubular solenoid is created, capable of directly encircling and centering the acted objects in it, bringing about convenient and innovative electromagnetic energy conversion for electromagnetic heating, electromagnetic excitation, physical information capture, and electro-mechanical motion used in science research, industry, and even biomedical activities.

  5. NASA Open Rotor Noise Research

    NASA Technical Reports Server (NTRS)

    Envia, Ed

    2010-01-01

    Owing to their inherent fuel burn efficiency advantage compared with the current generation high bypass ratio turbofan engines, there is resurgent interest in developing open rotor propulsion systems for powering the next generation commercial aircraft. However, to make open rotor systems truly competitive, they must be made to be acoustically acceptable too. To address this challenge, NASA in collaboration with industry is exploring the design space for low-noise open rotor propulsion systems. The focus is on the system level assessment of the open rotors compared with other candidate concepts like the ultra high bypass ratio cycle engines. To that end there is an extensive research effort at NASA focused on component testing and diagnostics of the open rotor acoustic performance as well as assessment and improvement of open rotor noise prediction tools. In this presentation and overview of the current NASA research on open rotor noise will be provided. Two NASA projects, the Environmentally Responsible Aviation Project and the Subsonic Fixed Wing Project, have been funding this research effort.

  8. openBEB: open biological experiment browser for correlative measurements

    PubMed Central

    2014-01-01

    Background New experimental methods must be developed to study interaction networks in systems biology. To reduce biological noise, individual subjects, such as single cells, should be analyzed using high throughput approaches. The measurement of several correlative physical properties would further improve data consistency. Accordingly, a considerable quantity of data must be acquired, correlated, catalogued and stored in a database for subsequent analysis. Results We have developed openBEB (open Biological Experiment Browser), a software framework for data acquisition, coordination, annotation and synchronization with database solutions such as openBIS. OpenBEB consists of two main parts: A core program and a plug-in manager. Whereas the data-type independent core of openBEB maintains a local container of raw-data and metadata and provides annotation and data management tools, all data-specific tasks are performed by plug-ins. The open architecture of openBEB enables the fast integration of plug-ins, e.g., for data acquisition or visualization. A macro-interpreter allows the automation and coordination of the different modules. An update and deployment mechanism keeps the core program, the plug-ins and the metadata definition files in sync with a central repository. Conclusions The versatility, the simple deployment and update mechanism, and the scalability in terms of module integration offered by openBEB make this software interesting for a large scientific community. OpenBEB targets three types of researcher, ideally working closely together: (i) Engineers and scientists developing new methods and instruments, e.g., for systems-biology, (ii) scientists performing biological experiments, (iii) theoreticians and mathematicians analyzing data. The design of openBEB enables the rapid development of plug-ins, which will inherently benefit from the “house keeping” abilities of the core program. We report the use of openBEB to combine live cell microscopy, microfluidic control and visual proteomics. In this example, measurements from diverse complementary techniques are combined and correlated. PMID:24666611

    2011-02-01

    Demand response (DR) is becoming an increasingly important part of power grid planning and operation. The advent of the Smart Grid, which mandates its use, further motivates selection and development of suitable software protocols to enable DR functionality. The OpenADR protocol has been developed and is being standardized to serve this goal. We believe that the development of a distributable, open source implementation of OpenADR will benefit this effort and motivate critical evaluation of its capabilities, by the wider community, for providing wide-scale DR services

    Dettmann, Carl P

    2010-01-01

    We investigate mushroom billiards, a class of dynamical systems with sharply divided phase space. For typical values of the control parameter of the system $\\rho$, an infinite number of marginally unstable periodic orbits (MUPOs) exist making the system sticky in the sense that unstable orbits approach regular regions in phase space and thus exhibit regular behaviour for long periods of time. The problem of finding these MUPOs is expressed as the well known problem of finding optimal rational approximations of a real number, subject to some system-specific constraints. By introducing a generalized mushroom and using properties of continued fractions, we describe a zero measure set of control parameter values $\\rho\\in(0,1)$ for which all MUPOs are destroyed and therefore the system is less sticky. The open mushroom (billiard with a hole) is then considered in order to quantify the stickiness exhibited and exact leading order expressions for the algebraic decay of the survival probability function $P(t)$ are ca...

  2. The `Open Discovery' Challenge

    NASA Astrophysics Data System (ADS)

    Wren, Jonathan D.

    One of the most exciting goals of literature-based discovery is the inference of new, previously undocumented relationships based upon an analysis of known relationships. Human ability to read and assimilate scientific information has long lagged the rate by which new information is produced, and the rapid accumulation of published literature has exacerbated this problem further. The idea that a computer could begin to take over part of the hypothesis formation process that has long been solely within the domain of human reason has been met with both skepticism and excitement, both of which are fully merited. Conceptually, it has already been demonstrated in several studies that a computational approach to literature analysis can lead to the generation of novel and fruitful hypotheses. The biggest barriers to progress in this field are technical in nature, dealing mostly with the shortcomings that computers have relative to humans in understanding the nature, importance and implications of relationships found in the literature. This chapter will discuss where current efforts have brought us in solving the open-discovery problem, and what barriers are limiting further progress.

  3. Uganda opens new fronts.

    PubMed

    Tebere, R

    1991-03-01

    AIDS and HIV figures released in June 1990 by Uganda's AIDS Control Programme (ACP) prompted the revamping of the country's national AIDS initiative, the passage of legislation designed to stamp out sexual exploitation of minors and a reluctant pledge by President Yoweri Museveni to advocate condom use. Uganda has a massive AIDS prevention campaign estimated to reach 80% of the population, but AIDS cases are doubling every 6 months according to Health Minister Zack Kaheru. Sexually transmitted diseases (STDs) have been linked as a co-factor in HIV transmission, therefore treatment of STDs will be linked to the anti-AIDS campaign in free clinics for the treatment of STDs operating in Kampala and Jinja and in new ones planned for Mbale, Mbarara and Fort Portal. The Uganda Aids Commission was created in an effort to strengthen the ACP by insuring that all government departments address AIDS prevention. New laws designed to curb the spread of the disease by sexual contact raised the age of consent for sexual intercourse from 14 to 18 years of age, made prostitution and homosexuality illegal and redefined incest to include extended family members. President Museveni urged Ugandans to use condoms to protect themselves from HIV infection. Because condoms are not 100% reliable, and because their use is not a popular option among rural people due to cultural and religious beliefs, President Museveni and ACP Director Dr. Warren Namara agree that the ultimate weapon against AIDS is educating people to rethink their sexual attitudes and actions. Hopeful signs include more openness about AIDS and more seeking of information about AIDS among the people. PMID:12283896

  4. Open Geoscience Database

    NASA Astrophysics Data System (ADS)

    Bashev, A.

    2012-04-01

    Currently there is an enormous amount of various geoscience databases. Unfortunately the only users of the majority of the databases are their elaborators. There are several reasons for that: incompaitability, specificity of tasks and objects and so on. However the main obstacles for wide usage of geoscience databases are complexity for elaborators and complication for users. The complexity of architecture leads to high costs that block the public access. The complication prevents users from understanding when and how to use the database. Only databases, associated with GoogleMaps don't have these drawbacks, but they could be hardly named "geoscience" Nevertheless, open and simple geoscience database is necessary at least for educational purposes (see our abstract for ESSI20/EOS12). We developed a database and web interface to work with them and now it is accessible at maps.sch192.ru. In this database a result is a value of a parameter (no matter which) in a station with a certain position, associated with metadata: the date when the result was obtained; the type of a station (lake, soil etc); the contributor that sent the result. Each contributor has its own profile, that allows to estimate the reliability of the data. The results can be represented on GoogleMaps space image as a point in a certain position, coloured according to the value of the parameter. There are default colour scales and each registered user can create the own scale. The results can be also extracted in *.csv file. For both types of representation one could select the data by date, object type, parameter type, area and contributor. The data are uploaded in *.csv format: Name of the station; Lattitude(dd.dddddd); Longitude(ddd.dddddd); Station type; Parameter type; Parameter value; Date(yyyy-mm-dd). The contributor is recognised while entering. This is the minimal set of features that is required to connect a value of a parameter with a position and see the results. All the complicated data treatment could be conducted in other programs after extraction the filtered data into *.csv file. It makes the database understandable for non-experts. The database employs open data format (*.csv) and wide spread tools: PHP as the program language, MySQL as database management system, JavaScript for interaction with GoogleMaps and JQueryUI for create user interface. The database is multilingual: there are association tables, which connect with elements of the database. In total the development required about 150 hours. The database still has several problems. The main problem is the reliability of the data. Actually it needs an expert system for estimation the reliability, but the elaboration of such a system would take more resources than the database itself. The second problem is the problem of stream selection - how to select the stations that are connected with each other (for example, belong to one water stream) and indicate their sequence. Currently the interface is English and Russian. However it can be easily translated to your language. But some problems we decided. For example problem "the problem of the same station" (sometimes the distance between stations is smaller, than the error of position): when you adding new station to the database our application automatically find station near this place. Also we decided problem of object and parameter type (how to regard "EC" and "electrical conductivity" as the same parameter). This problem has been solved using "associative tables". If you would like to see the interface on your language, just contact us. We should send you the list of terms and phrases for translation on your language. The main advantage of the database is that it is totally open: everybody can see, extract the data from the database and use them for non-commercial purposes with no charge. Registered users can contribute to the database without getting paid. We hope, that it will be widely used first of all for education purposes, but professional scientists could use it also.

  5. Open laminoforaminotomy: A lost art?

    PubMed Central

    Epstein, Nancy E.

    2015-01-01

    Background: Open cervical laminoforaminotomy (CLF) provides safe and effective decompression/excision of lateral/foraminal disc herniations/spurs contributing to nerve root compression. CLF's advantages over anterior cervical discectomy/fusion (ACDF) include the lack of risk to anterior structures (esophagus, trachea, carotid, and recurrent laryngeal nerve) and the avoidance of a fusion. Further, advantages over minimally invasive surgery CLF (MIS CLF) include a lower incidence of dural tears, infections, and neural injury. Furthermore, complications are now more often reported in medicolegal suits rather than the spinal surgical literature. Methods: Here, in a select review of the spinal literature in which we specifically focused on the benefits, risks, and complication of open CLF versus the various MIS CLS techniques. Results: Open CLF is a unique posterior cervical surgical technique that is technically demanding. When using an MIS CLF approach that provides limited visualization and maneuverability while incurring greater morbidity (e.g., risks more dural tears, infection, and neural damage). Conclusions: Why not utilize open CLF, adequately and safely, to decompress lateral/foraminally compromised cervical nerve roots, and avoid the risks of MIS CLF or ACDF? Presently, too many spine surgeons automatically choose MIS CLF or ACDF over open CLF; is this because it is a “lost art”? PMID:26693388

    In contrast with other imaging modalities, there is presently a scarcity of fully open resources in magnetoencephalography (MEG) available to the neuroimaging community. Here we present a collaborative effort led by the McConnell Brain Imaging Centre of the Montreal Neurological Institute, and the Université de Montréal to build and share a centralised repository to curate MEG data in raw and processed form for open dissemination. The Open MEG Archive (OMEGA, omega.bic.mni.mcgill.ca) is bound to become a continuously expanding repository of multimodal data with a primary focus on MEG, in addition to storing anatomical MRI volumes, demographic participant data and questionnaires, and other forms of electrophysiological data such as EEG. The OMEGA initiative offers both the technological framework for multi-site MEG data aggregation, and serves as one of the largest freely available resting-state and eventually task-related MEG datasets presently available.

    The Department of Energy’s (DOE’s) Building Technologies Office (BTO) is supporting the development of an open-source software tool for analyzing building energy and operational data: OpenEIS (open energy information system). This tool addresses the problems of both owners of building data and developers of tools to analyze this data. Building owners and managers have data but lack the tools to analyze it while tool developers lack data in a common format to ease development of reusable data analysis tools. This document is intended for developers of applications and explains the mechanisms for building analysis applications, accessing data, and displaying data using a visualization from the included library. A brief introduction to the visualizations can be used as a jumping off point for developers familiar with JavaScript to produce their own. Several example applications are included which can be used along with this document to implement algorithms for performing energy data analysis.

  15. The VLT Opening Symposium

    NASA Astrophysics Data System (ADS)

    1999-02-01

    Scientists Meet in Antofagasta to Discuss Front-Line Astrophysics To mark the beginning of the VLT era, the European Southern Observatory is organizing a VLT Opening Symposium which will take place in Antofagasta (Chile) on 1-4 March 1999, just before the start of regular observations with the ESO Very Large Telescope on April 1, 1999. The Symposium occupies four full days and is held on the campus of the Universidad Catolica del Norte. It consists of plenary sessions on "Science in the VLT Era and Beyond" and three parallel Workshops on "Clusters of Galaxies at High Redshift" , "Star-way to the Universe" and "From Extrasolar Planets to Brown Dwarfs" . There will be many presentations of recent work at the major astronomical facilities in the world. The meeting provides a very useful forum to discuss the latest developments and, in this sense, contributes to the planning of future research with the VLT and other large telescopes. The symposium will be opened with a talk by the ESO Director General, Prof. Riccardo Giacconi , on "Paranal - an observatory for the 21st century". It will be followed by reports about the first scientific results from the main astronomical instruments on VLT UT1, FORS1 and ISAAC. The Symposium participants will see the VLT in operation during special visits to the Paranal Observatory. Press conferences are being arranged each afternoon to inform about the highlights of the conference. After the Symposium, there will be an Official Inauguration Ceremony at Paranal on 5 March Contributions from ESO ESO scientists will make several presentations at the Symposium. They include general reviews of various research fields as well as important new data and results from the VLT that show the great potential of this new astronomical facility. Some of the recent work is described in this Press Release, together with images and spectra of a large variety of objects. Note that all of these data will soon become publicly available via the VLT Archive. The text below summarizes the individual projects. Comprehensive texts with all photos and diagrammes are available in nine separate web documents ( ESO PR Photos 08/99 to 16/99 ) that may be accessed via the links at the top of each section. The degree of detail and level of complexity of the texts depend on the subject and the available materials. 1. Dwarf Galaxies in the Local Group ESO PR Photo 10a/99 ESO PR Photo 10a/99 The Antlia Galaxy (FORS1 colour composite) . Access full text and PR Photos 10a-d/99 In addition to large spiral galaxies like the Milky Way Galaxy, the Andromeda Galaxy and Messier 33, the Local Group of Galaxies contains many dwarf galaxies. The VLT has observed two of these, Antlia and NGC 6822 . Antlia is a low-surface brightness, spheroidal dwarf galaxy that was only discovered in 1997. While it contains a large amount of atomic hydrogen at its centre, no young stars are found, and it appears that most of its stars are old. This is unlike other dwarf galaxies in the Milky Way neighbourhood, as star formation is expected to occur within dense hydrogen clouds. Further observations will be necessary to understand this unusual characteristics. The VLT also obtained images of an irregular dwarf galaxy in the Local Group, NGC 6822, as well as spectra of some of its stars. This galaxy is of the "irregular" type and is situated at a distance of about 2 million light-years. A comparison of the spectra of supergiant stars in NGC 6822 shows that many spectral lines are much weaker than in stars of similar type in the Milky Way, but of similar strength as in stars in the Small Magellanic Cloud. This confirms an earlier finding that NGC 6822 has chemical composition (a lower "metallicity") that is different from what is observed in our Galaxy. 2.

    OpenMP [13] is the dominant programming model for shared-memory parallelism in C, C++ and Fortran due to its easy-to-use directive-based style, portability and broad support by compiler vendors. Similar characteristics are needed for a programming model for devices such as GPUs and DSPs that are gaining popularity to accelerate compute-intensive application regions. This paper presents extensions to OpenMP that provide that programming model. Our results demonstrate that a high-level programming model can provide accelerated performance comparable to hand-coded implementations in CUDA.

    The Ocean Observatories Initiative is a long-term, NSF-funded program to provide 25-30 years of sustained ocean measurements to study climate variability, ocean circulation and ecosystem dynamics, air-sea exchange, seafloor processes, and plate-scale geodynamics. The OOI will enable powerful new scientific approaches for exploring the complexities of Earth-ocean-atmosphere interactions, thereby accelerating progress toward the goal of understanding, predicting, and managing our ocean environment. The OOI can foster new discoveries that, in turn, move research in unforeseen directions. The OOI Cyberinfrastructure will connect and coordinate the operations of OOI marine components and data processes, to meet the objectives of the oceanographic research and education communities. The CI will let all users easily interact with deployed resources, access collected data, and apply those data to their specific research and educational needs. The CI is a free and open product that adopts innovative and flexible strategies to bring the oceans to users, any time, any place, on any suitable device. The OOI CI is dedicated to "using the latest computing technologies to solve the interoperability problem among vast amounts of heterogeneous geospatial data from various sources." OOI CI's charge is to be transformative, and its technologies and goals are just that (see URL). The Cyberinfrastructure integrates state-of-the-art and best-practice approaches to provide fully interoperable access to the widest possible collection of geospatial data. From the system-of-systems model of the planned observatories and the ingestion of data, models, and services; to the configurable, automated workflows producing real-time products, data curation and quality management strategies are supported to the fullest possible extent. How do we build a system to efficiently support 750 core instruments across numerous platform types, add as-yet unknown instruments during the operations phase, and support any number of processes and external data in the system throughout its 25+ years of operation? What key strategies must be adopted, architectural approaches applied, and technologies integrated to provide complete discovery, access, and use of the system and its data? What defines the critical characteristics expected of the core system, the complete system, and the transformative system? And how can this system be leveraged by multiple science users, programs, and organizations beyond its initial target functionality? We will present the CI team's best responses to these questions. The project is completing Release 2, two-thirds of the way to a fully public release, and halfway to the final system. The engagement of OOI marine operations and marine science teams prepares us to support marine operations, and the software will be applied to "real operations" very soon. Most of the fundamental marine and operational scenarios are in place at a basic level, and the capabilities have been laid out for a full suite of mature operations and science activities. From these beginnings, we offer technical, social, and strategic perspectives on the challenges and solutions in geoinformatics data systems, and ask "Where to from here?" Funding for OOI is provided by the National Science Foundation through a Cooperative Agreement with the Consortium for Ocean Leadership, which in turn funds the CI project.

    We consider open dynamical systems, subject to external interventions by agents that are not completely described by the theory (classical or quantal). These interventions are localized in regions that are relatively spacelike. Under these circumstances, no relativistic transformation law exists that relates the descriptions of the physical system by observers in relative motion. Still, physical laws are the same in all Lorentz frames.

    Craciunescu, Vasile; Iosifescu, Ionut; Ilie, Codrina Maria; Gaitanaru, Dragos; Radu Gogu, Constantin; Hurni, Lorenz

    2013-04-01

    The concept of open data access is a very important topic nowadays. The concept assumes that all data collected or generated by public sector bodies (excepting personal data and data protected under existing privacy protection or accessibility rules) is made publicly accessible in commonly-used, machine-readable formats and can be re-used for any purpose, commercial or non-commercial. Governmental agencies are considered to be the most significant data owners and providers in modern societies. The sheer volume and wealth of this data makes apparent the potential benefits of reusing, combining, and processing governmental data. Even though metadata (information about the data) is sometimes published, administrations typically express reluctance to making their data available, for various reasons, cultural, political, legal, institutional and technical. The governmental spatial information (also called geospatial data, georeferenced data or geodata) producers in Romania are no exception -with the additional situation that even metadata is not usually available. Starting from 2013 a joint program between a Swiss partner (The Swiss Federal Institute of Technology ETH- Zurich - Institute of Cartography and Geoinformation) and a Romanian partner (Technical University of Civil Engineering - UTCB) is developed in order to establish a new approach on the open geodata topic. The main objective of the project GEOIDEA.RO (GEodata Openness Initiative for Development and Economic Advancement in ROmania) is to improve the scientific basis for open geodata model adoption in Romania. Is our believe that publishing government geodata in Romania over the Internet,under an open license and in a reusable format can strengthen citizen engagement and yield new innovative businesses, bringing substantial social and economic gains.

  1. OpenFOAM: Open source CFD in research and industry

    NASA Astrophysics Data System (ADS)

    Jasak, Hrvoje

    2009-12-01

    The current focus of development in industrial Computational Fluid Dynamics (CFD) is integration of CFD into Computer-Aided product development, geometrical optimisation, robust design and similar. On the other hand, in CFD research aims to extend the boundaries ofpractical engineering use in "non-traditional " areas. Requirements of computational flexibility and code integration are contradictory: a change of coding paradigm, with object orientation, library components, equation mimicking is proposed as a way forward. This paper describes OpenFOAM, a C++ object oriented library for Computational Continuum Mechanics (CCM) developed by the author. Efficient and flexible implementation of complex physical models is achieved by mimicking the form ofpartial differential equation in software, with code functionality provided in library form. Open Source deployment and development model allows the user to achieve desired versatility in physical modeling without the sacrifice of complex geometry support and execution efficiency.

  2. Open Source, Open Standards, and Health Care Information Systems

    PubMed Central

    2011-01-01

    Recognition of the improvements in patient safety, quality of patient care, and efficiency that health care information systems have the potential to bring has led to significant investment. Globally the sale of health care information systems now represents a multibillion dollar industry. As policy makers, health care professionals, and patients, we have a responsibility to maximize the return on this investment. To this end we analyze alternative licensing and software development models, as well as the role of standards. We describe how licensing affects development. We argue for the superiority of open source licensing to promote safer, more effective health care information systems. We claim that open source licensing in health care information systems is essential to rational procurement strategy. PMID:21447469

  3. Limits to Open Class Performance?

    NASA Technical Reports Server (NTRS)

    Bowers, Albion H.

    2008-01-01

    This presentation discusses open or unlimited class aircraft performance limitations and design solutions. Limitations in this class of aircraft include slow climbing flight which requires low wing loading, high cruise speed which requires high wing loading, gains in induced or viscous drag alone which result in only half the gain overall and other structural problems (yaw inertia and spins, flutter and static loads integrity). Design solutions include introducing minimum induced drag for a given span (elliptical span load or winglets) and introducing minimum induced drag for a bell shaped span load. It is concluded that open class performance limits (under current rules and technologies) is very close to absolute limits, though some gains remain to be made from unexplored areas and new technologies.

  9. Inflation on an Open Racetrack

    SciTech Connect

    Chen, Heng-Yu; Hung, Ling-Yan; Shiu, Gary; /Wisconsin U., Madison /SLAC /Stanford U., Phys. Dept.

    2011-11-14

    We present a variant of warped D-brane inflation by incorporating multiple sets of holomorphically - embedded D7-branes involved in moduli stabilization with extent into a warped throat. The resultant D3-brane motion depends on the D7-brane configuration and the relative position of the D3-brane in these backgrounds. The non-perturbative moduli stabilization superpotential takes the racetrack form, but the additional D3-brane open string moduli dependence provides more flexibilities in model building. For concreteness, we consider D3-brane motion in the warped deformed conifold with the presence of multiple D7-branes, and derive the scalar potential valid for the entire throat. By explicit tuning of the microphysical parameters, we obtain inflationary trajectories near an inflection point for various D7-brane configurations. Moreover, the open racetrack potential admits approximate Minkowski vacua before uplifting. We demonstrate with a concrete D-brane inflation model where the Hubble scale during inflation can exceed the gravitino mass. Finally, the multiple sets of D7-branes present in this open racetrack setup also provides a mechanism to stabilize the D3-brane to metastable vacua in the intermediate region of the warped throat.

  10. OPENING ANGLES OF COLLAPSAR JETS

    SciTech Connect

    Mizuta, Akira; Ioka, Kunihito

    2013-11-10

    We investigate the jet propagation and breakout from the stellar progenitor for gamma-ray burst (GRB) collapsars by performing two-dimensional relativistic hydrodynamic simulations and analytical modeling. We find that the jet opening angle is given by ?{sub j} ? 1/5?{sub 0} and infer the initial Lorentz factor of the jet at the central engine, ?{sub 0}, is a few for existing observations of ?{sub j}. The jet keeps the Lorentz factor low inside the star by converging cylindrically via collimation shocks under the cocoon pressure and accelerates at jet breakout before the free expansion to a hollow-cone structure. In this new picture, the GRB duration is determined by the sound crossing time of the cocoon, after which the opening angle widens, reducing the apparent luminosity. Some bursts violating the maximum opening angle ?{sub j,{sub max}} ? 1/5 ? 12° imply the existence of a baryon-rich sheath or a long-acting jet. We can explain the slopes in both Amati and Yonetoku spectral relations using an off-centered photosphere model, if we make only one assumption that the total jet luminosity is proportional to the initial Lorentz factor of the jet. We also numerically calibrate the pre-breakout model (Bromberg et al.) for later use.

  11. Ultimate open pit stochastic optimization

    NASA Astrophysics Data System (ADS)

    Marcotte, Denis; Caron, Josiane

    2013-02-01

    Classical open pit optimization (maximum closure problem) is made on block estimates, without directly considering the block grades uncertainty. We propose an alternative approach of stochastic optimization. The stochastic optimization is taken as the optimal pit computed on the block expected profits, rather than expected grades, computed from a series of conditional simulations. The stochastic optimization generates, by construction, larger ore and waste tonnages than the classical optimization. Contrary to the classical approach, the stochastic optimization is conditionally unbiased for the realized profit given the predicted profit. A series of simulated deposits with different variograms are used to compare the stochastic approach, the classical approach and the simulated approach that maximizes expected profit among simulated designs. Profits obtained with the stochastic optimization are generally larger than the classical or simulated pit. The main factor controlling the relative gain of stochastic optimization compared to classical approach and simulated pit is shown to be the information level as measured by the boreholes spacing/range ratio. The relative gains of the stochastic approach over the classical approach increase with the treatment costs but decrease with mining costs. The relative gains of the stochastic approach over the simulated pit approach increase both with the treatment and mining costs. At early stages of an open pit project, when uncertainty is large, the stochastic optimization approach appears preferable to the classical approach or the simulated pit approach for fair comparison of the values of alternative projects and for the initial design and planning of the open pit.

    1985-06-01

    RCRA provides for publication of an inventory of open dumps. The Act defines open dumps as facilities which do not comply with EPA's Criteria for Classification of SW Disposal Facilities and Practices (40 CFR 257). To aid the States in satisfying the requirement that the solid waste management plan shall provide for the closing or upgrading of all existing open dumps within the State, EPA has funded State efforts to identify open dumps so that they can plan to provide for their closure or upgrading. In furtherance of this planning effort, the Act requires that EPA publish an inventory of open dumps. Publication of the inventory will serve to inform the Congress and the public of those facilities which the states have found to be open dumps.

    Stationary spatially localized structures, sometimes called dissipative solitons, arise in many interesting and important applications, including buckling of slender structures under compression, nonlinear optics, fluid flow, surface catalysis, neurobiology and many more. The recent resurgence in interest in these structures has led to significant advances in our understanding of the origin and properties of these states, and these in turn suggest new questions, both general and system-specific. This paper surveys these results focusing on open problems, both mathematical and computational, as well as on new applications.

    The memory model of OpenMP has been widely misunderstood since the first OpenMP specification was published in 1997 (Fortran 1.0). The proposed OpenMP specification (version 2.5) includes a memory model section to address this issue. This section unifies and clarifies the text about the use of memory in all previous specifications, and relates the model to well-known memory consistency semantics. In this paper, we discuss the memory model and show its implications for future distributed shared memory implementations of OpenMP.

    Open PHACTS is a public-private partnership between academia, publishers, small and medium sized enterprises and pharmaceutical companies. The goal of the project is to deliver and sustain an 'open pharmacological space' using and enhancing state-of-the-art semantic web standards and technologies. It is focused on practical and robust applications to solve specific questions in drug discovery research. OPS is intended to facilitate improvements in drug discovery in academia and industry and to support open innovation and in-house non-public drug discovery research. This paper lays out the challenges and how the Open PHACTS project is hoping to address these challenges technically and socially. PMID:22683805

  4. Will this open space work?

    PubMed

    Vischer, J

    1999-01-01

    Northern Oil is moving offices, and CEO Fritz Schumacher wants to make the most of the move in this fictional case study. He believes that adopting an open-plan work space will reinvent how the company works, not to mention cut costs. Facilities manager Sasha Pasternak also supports the open plan. Her job would be easier, and her budget would stretch further, if Northern had standardized workstations and used partitions, not walls. And she likes the way the new design flattens the organization: everyone has the same amount of space and the same ergonomically sound furniture. The new building would have more conference rooms and just-in-time work spaces for employees who worked mostly off-site. And although she knew that initial meetings between the architects and Northern employees hadn't yielded much support for open space--people were attached to their private offices--she expected that people would warm to the idea. But when the new design was unveiled, employees were less than enthusiastic. They hurled questions like, How will workers concentrate if they can't shut their office doors? How will people have confidential meetings with their boss? And why would people stay at Northern when the competition offers them private offices? There was even talk of circulating a petition refusing to move to the new space. A week later, the architect presented revised plans to the project group. The new options would add costs and reduce the amount of space savings, but offering a choice to employees might make them feel less threatened. What should the project team do? Five commentators offer advice. PMID:10387577

  5. Macroeconomics in an open economy.

    PubMed

    Cooper, R N

    1986-09-12

    The customary treatment of national economies as closed and self-contained must be substantially modified to allow for those economies that typically trade goods, services, and securities with other countries in increasing volume. Open economy macroeconomics is essential to understanding the major events of the U.S. economy over the past half dozen years. Both the sharp rise in the dollar and the unprecedentedly large U.S. trade deficit are linked to the U.S. budget deficit, as is the drop in the rate of inflation. PMID:17756868

  6. Quasiequilibria in open quantum systems

    Walls, Jamie D.

    2010-03-15

    In this work, the steady-state or quasiequilibrium resulting from periodically modulating the Liouvillian of an open quantum system, L-circumflex-circumflex(t), is investigated. It is shown that differences between the quasiequilibrium and the instantaneous equilibrium occur due to nonadiabatic contributions from the gauge field connecting the instantaneous eigenstates of L-circumflex-circumflex(t) to a fixed basis. These nonadiabatic contributions are shown to result in an additional rotation and/or depolarization for a single spin-1/2 in a time-dependent magnetic field and to affect the thermal mixing of two coupled spins interacting with a time-dependent magnetic field.

  15. Java based open architecture controller

    SciTech Connect

    Weinert, G F

    2000-01-13

    At Lawrence Livermore National Laboratory (LLNL) the authors have been developing an open architecture machine tool controller. This work has been patterned after the General Motors (GM) led Open Modular Architecture Controller (OMAC) work, where they have been involved since its inception. The OMAC work has centered on creating sets of implementation neutral application programming interfaces (APIs) for machine control software components. In the work at LLNL, they were among the early adopters of the Java programming language. As an application programming language, it is particularly well suited for component software development. The language contains many features, which along with a well-defined implementation API (such as the OMAC APIs) allows third party binary files to be integrated into a working system. Because of its interpreted nature, Java allows rapid integration testing of components. However, for real-time systems development, the Java programming language presents many drawbacks. For instance, lack of well defined scheduling semantics and threading behavior can present many unwanted challenges. Also, the interpreted nature of the standard Java Virtual Machine (JVM) presents an immediate performance hit. Various real-time Java vendors are currently addressing some of these drawbacks. The various pluses and minuses of using the Java programming language and environment, with regard to a component-based controller, will be outlined.

  16. Open questions in classical gravity

    SciTech Connect

    Mannheim, P.D. )

    1994-04-01

    In this work, the authors discuss some outstanding open questions regarding the validity and uniqueness of the standard second-order Newton-Einstein classical gravitational theory. On the observational side the authors discuss the degree to which the realm of validity of Newton's law of gravity can actually be extended to distances much larger than the solar system distance scales on which the law was originally established. On the theoretical side the authors identify some commonly accepted (but actually still open to question) assumptions which go into the formulation of the standard second-order Einstein theory in the first place. In particular, it is shown that while the familiar second-order Poisson gravitational equation (and accordingly its second-order covariant Einstein generalization) may be sufficient to yield Newton's law of gravity they are not in fact necessary. The standard theory thus still awaits the identification of some principle which would then make it necessary too. It is shown that current observational information does not exclusively mandate the standard theory, and that the conformal invariant fourth-order theory of gravity considered recently by Mannheim and Kazanas is also able to meet the constraints of data, and in fact to do so without the need for any so far unobserved nonluminous or dark matter. 37 refs., 7 figs.

  16. Defining an Open Source Strategy for NASA

    NASA Astrophysics Data System (ADS)

    Mattmann, C. A.; Crichton, D. J.; Lindsay, F.; Berrick, S. W.; Marshall, J. J.; Downs, R. R.

    2011-12-01

    Over the course of the past year, we have worked to help frame a strategy for NASA and open source software. This includes defining information processes to understand open source licensing, attribution, commerciality, redistribution, communities, architectures, and interactions within the agency. Specifically we held a training session at the NASA Earth Science Data Systems Working Group meeting in Open Source software as it relates to the NASA Earth Science data systems enterprise, including EOSDIS, the Distributed Active Archive Centers (DAACs), ACCESS proposals, and the MEASURES communities, and efforts to understand how open source software can be both consumed and produced within that ecosystem. In addition, we presented at the 1st NASA Open Source Summit (OSS) and helped to define an agency-level strategy, a set of recommendations and paths forward for how to identify healthy open source communities, how to deal with issues such as contributions originating from other agencies, and how to search out talent with the right skills to develop software for NASA in the modern age. This talk will review our current recommendations for open source at NASA, and will cover the set of thirteen recommendations output from the NASA Open Source Summit and discuss some of their implications for the agency.

  17. Meromorphic open-string vertex algebras

    E-print Network

    Yi-Zhi Huang

    2012-04-09

    A notion of meromorphic open-string vertex algebra is introduced. A meromorphic open-string vertex algebra is an open-string vertex algebra in the sense of Kong and the author satisfying additional rationality (or meromorphicity) conditions for vertex operators. The vertex operator map for a meromorphic open-string vertex algebra satisfies rationality and associativity but in general does not satisfy the Jacobi identity, commutativity, the commutator formula, the skew-symmetry or even the associator formula. Given a vector space \\mathfrak{h}, we construct a meromorphic open-string vertex algebra structure on the tensor algebra of the negative part of the affinization of \\mathfrak{h} such that the vertex algebra struture on the symmetric algebra of the negative part of the Heisenberg algebra associated to \\mathfrak{h} is a quotient of this meromorphic open-string vertex algebra. We also introduce the notion of left module for a meromorphic open-string vertex algebra and construct left modules for the meromorphic open-string vertex algebra above.

  15. Measured opening characteristics of an electromagnetically opened diaphragm for the Langley expansion tunnel

    NASA Technical Reports Server (NTRS)

    Moore, J. A.

    1976-01-01

    Results from an experimental study of the opening characteristics of an electromagnetically opened, 15.24 cm diameter diaphragm are presented. This diaphragm consists of a polyester film bonded to a preformed wire and is opened by passing a current pulse (capacitor discharge) through the wire. The diaphragm separates the acceleration section of the expansion tunnel from the nozzle so that the nozzle may be at a lower pressure than the acceleration section prior to a test. Opening times and cleanness of the opened area were examined for dependence on diaphragm thickness, on wire diameter, on technique of bonding the wire to the diaphragm, and on voltage and energy level of the energy source. Time histories of the pitot pressure measured at the expansion-tunnel nozzle entrance location are presented for (1) no diaphragm, (2) a flow-opened diaphragm, and (3) an electromagnetically opened diaphragm.

    NASA is researching open rotor propulsion as part of its technology research and development plan for addressing the subsonic transport aircraft noise, emission and fuel burn goals. The low-speed wind tunnel test for investigating the aerodynamic and acoustic performance of a benchmark blade set at the approach and takeoff conditions has recently concluded. A high-speed wind tunnel diagnostic test campaign has begun to investigate the performance of this benchmark open rotor blade set at the cruise condition. Databases from both speed regimes will comprise a comprehensive collection of benchmark open rotor data for use in assessing/validating aerodynamic and noise prediction tools (component & system level) as well as providing insights into the physics of open rotors to help guide the development of quieter open rotors.

  17. How to deal with an open abdomen?

    PubMed

    De Waele, Jan J; Kaplan, Mark; Sugrue, Michael; Sibaja, Pablo; Björck, Martin

    2015-01-01

    Appropriate open abdomen treatment is one of the key elements in the management of patients who require decompressive laparotomy or in whom the abdomen is left open prophylactically. Apart from fluid control and protection from external injury, fluid evacuation and facilitation of early closure are now the goals of open abdomen treatment. Abdominal negative pressure therapy has emerged as the most appropriate method to reach these goals. Especially when combined with strategies that allow progressive approximation of the fascial edges, high closure rates can be obtained. Intra-abdominal pressure measurement can be used to guide the surgical strategy and continued attention to intra-abdominal hypertension is necessary. This paper reviews recent advances as well as identifying the remaining challenges in patients requiring open abdomen treatment. The new classification system of the open abdomen is an important tool to use when comparing the efficacy of different strategies, as well as different systems of temporary abdominal closure.

    Duchange, Nathalie; Autard, Delphine; Pinhas, Nicole

    2008-01-01

    Open access within the scientific community depends on the scientific context and the practices of the field. In the biomedical domain, the communication of research results is characterised by the importance of the peer reviewing process, the existence of a hierarchy among journals and the transfer of copyright to the editor. Biomedical publishing has become a lucrative market and the growth of electronic journals has not helped lower the costs. Indeed, it is difficult for today's public institutions to gain access to all the scientific literature. Open access is thus imperative, as demonstrated through the positions taken by a growing number of research funding bodies, the development of open access journals and efforts made in promoting open archives. This article describes the setting up of an Inserm portal for publication in the context of the French national protocol for open-access self-archiving and in an international context. PMID:18789227

  20. Achieving open access to conservation science.

    PubMed

    Fuller, Richard A; Lee, Jasmine R; Watson, James E M

    2014-12-01

    Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed the extent to which scientific research published since the year 2000 in 20 conservation science journals is publicly available. Of the 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 papers (4.88%) meet the standard definition of open access in which material can be freely reused providing attribution to the authors is given. This compares poorly with a comparable set of 20 evolutionary biology journals, where 31.93% of papers are freely downloadable and 7.49% are open access. Seventeen of the 20 conservation journals offer an open access option, but fewer than 5% of the papers are available through open access. The cost of accessing the full body of conservation science runs into tens of thousands of dollars per year for institutional subscribers, and many conservation practitioners cannot access pay-per-view science through their workplace. However, important initiatives such as Research4Life are making science available to organizations in developing countries. We urge authors of conservation science to pay for open access on a per-article basis or to choose publication in open access journals, taking care to ensure the license allows reuse for any purpose providing attribution is given. Currently, it would cost $51 million to make all conservation science published since 2000 freely available by paying the open access fees currently levied to authors. Publishers of conservation journals might consider more cost effective models for open access and conservation-oriented organizations running journals could consider a broader range of options for open access to nonmembers such as sponsorship of open access via membership fees.

  1. Open inflation in the landscape

    NASA Astrophysics Data System (ADS)

    Yamauchi, Daisuke; Linde, Andrei; Naruko, Atsushi; Sasaki, Misao; Tanaka, Takahiro

    2011-08-01

    The open inflation scenario is attracting a renewed interest in the context of the string landscape. Since there are a large number of metastable de Sitter vacua in the string landscape, tunneling transitions to lower metastable vacua through the bubble nucleation occur quite naturally, which leads to a natural realization of open inflation. Although the deviation of ?0 from unity is small by the observational bound, we argue that the effect of this small deviation on the large-angle CMB anisotropies can be significant for tensor-type perturbation in the open inflation scenario. We consider the situation in which there is a large hierarchy between the energy scale of the quantum tunneling and that of the slow-roll inflation in the nucleated bubble. If the potential just after tunneling is steep enough, a rapid-roll phase appears before the slow-roll inflation. In this case the power spectrum is basically determined by the Hubble rate during the slow-roll inflation. On the other hand, if such a rapid-roll phase is absent, the power spectrum keeps the memory of the high energy density there in the large angular components. Furthermore, the amplitude of large angular components can be enhanced due to the effects of the wall fluctuation mode if the bubble wall tension is small. Therefore, although even the dominant quadrupole component is suppressed by the factor (1-?0)2, one can construct some models in which the deviation of ?0 from unity is large enough to produce measurable effects. We also consider a more general class of models, where the false vacuum decay may occur due to Hawking-Moss tunneling, as well as the models involving more than one scalar field. We discuss scalar perturbations in these models and point out that a large set of such models is already ruled out by observational data, unless there was a very long stage of slow-roll inflation after the tunneling. These results show that observational data allow us to test various assumptions concerning the structure of the string theory potentials and the duration of the last stage of inflation.

    Grice, N.A.; Dawson, D.W. Western Connecticut State Univ., Danbury, CT )

    1990-08-01

    NGC 6716 is a young open star cluster in Sagittarius. Lindoff (1971) obtained photoelectric photometry for 12 stars and photographic UBV photometry for 115 stars in the cluster field down to V = 13.8. This work has been expanded to include more photoelectric standards and IRIS photometry for 332 stars in the cluster field down to V = 16. A reddening E(B-V) = 0.17 mag, a distance modulus of 8.69 + or - 0.15 mag (d = 547 pc), and an age of around 100 million years for the cluster are derived. Of the stars studied, 75 were judged as likely cluster members, 63 as possible members, and 194 as probable nonmembers. 13 refs.

  3. Summing Planar Bosonic Open Strings

    SciTech Connect

    Bardakci, Korkut

    2006-02-16

    In earlier work, planar graphs of massless {phi}{sup 3} theory were summed with the help of the light cone world sheet picture and the mean field approximation. In the present article, the same methods are applied to the problem of summing planar bosonic open strings. They find that in the ground state of the system, string boundaries form a condensate on the world sheet, and a new string emerges from this summation. Its slope is always greater than the initial slope, and it remains non-zero even when the initial slope is set equal to zero. If they assume the initial string tends to a field a theory in the zero slope limit, this result provides evidence for string formation in field theory.

    The LIGO Open Science Center (LOSC) fulfills LIGO's commitment to release, archive, and serve LIGO data in a broadly accessible way to the scientific community and to the public, and to provide the information and tools necessary to understand and use the data. In August 2014, the LOSC published the full dataset from Initial LIGO's "S5" run at design sensitivity, the first such large-scale release and a valuable testbed to explore the use of LIGO data by non-LIGO researchers and by the public, and to help teach gravitational-wave data analysis to students across the world. In addition to serving the S5 data, the LOSC web portal (losc.ligo.org) now offers documentation, data-location and data-quality queries, tutorials and example code, and more. We review the mission and plans of the LOSC, focusing on the S5 data release.

  6. Open issues in MPI implementation.

    Thakur, R.; Gropp, W.; Mathematics and Computer Science

    2007-01-01

    MPI (the Message Passing Interface) continues to be the dominant programming model for parallel machines of all sizes, from small Linux clusters to the largest parallel supercomputers such as IBM Blue Gene/L and Cray XT3. Although the MPI standard was released more than 10 years ago and a number of implementations of MPI are available from both vendors and research groups, MPI implementations still need improvement in many areas. In this paper, we discuss several such areas, including performance, scalability, fault tolerance, support for debugging and verification, topology awareness, collective communication, derived datatypes, and parallel I/O. We also present results from experiments with several MPI implementations (MPICH2, Open MPI, Sun, IBM) on a number of platforms (Linux clusters, Sun and IBM SMPs) that demonstrate the need for performance improvement in one-sided communication and support for multithreaded programs.

  7. Open Architecture SDR for Space

    NASA Technical Reports Server (NTRS)

    Smith, Carl; Long, Chris; Liebetreu, John; Reinhart, Richard C.

    2005-01-01

    This paper describes an open-architecture SDR (software defined radio) infrastructure that is suitable for space-based operations (Space-SDR). SDR technologies will endow space and planetary exploration systems with dramatically increased capability, reduced power consumption, and significantly less mass than conventional systems, at costs reduced by vigorous competition, hardware commonality, dense integration, reduced obsolescence, interoperability, and software re-use. Significant progress has been recorded on developments like the Joint Tactical Radio System (JSTRS) Software Communication Architecture (SCA), which is oriented toward reconfigurable radios for defense forces operating in multiple theaters of engagement. The JTRS-SCA presents a consistent software interface for waveform development, and facilitates interoperability, waveform portability, software re-use, and technology evolution.

  8. DISCONNECTING OPEN SOLAR MAGNETIC FLUX

    SciTech Connect

    DeForest, C. E.; Howard, T. A.; McComas, D. J.

    2012-01-20

    Disconnection of open magnetic flux by reconnection is required to balance the injection of open flux by coronal mass ejections and other eruptive events. Making use of recent advances in heliospheric background subtraction, we have imaged many abrupt disconnection events. These events produce dense plasma clouds whose distinctive shape can now be traced from the corona across the inner solar system via heliospheric imaging. The morphology of each initial event is characteristic of magnetic reconnection across a current sheet, and the newly disconnected flux takes the form of a 'U-'shaped loop that moves outward, accreting coronal and solar wind material. We analyzed one such event on 2008 December 18 as it formed and accelerated at 20 m s{sup -2} to 320 km s{sup -1}, thereafter expanding self-similarly until it exited our field of view 1.2 AU from the Sun. From acceleration and photometric mass estimates we derive the coronal magnetic field strength to be 8 {mu}T, 6 R{sub Sun} above the photosphere, and the entrained flux to be 1.6 Multiplication-Sign 10{sup 11} Wb (1.6 Multiplication-Sign 10{sup 19} Mx). We model the feature's propagation by balancing inferred magnetic tension force against accretion drag. This model is consistent with the feature's behavior and accepted solar wind parameters. By counting events over a 36 day window, we estimate a global event rate of 1 day{sup -1} and a global solar minimum unsigned flux disconnection rate of 6 Multiplication-Sign 10{sup 13} Wb yr{sup -1} (6 Multiplication-Sign 10{sup 21} Mx yr{sup -1}) by this mechanism. That rate corresponds to {approx} - 0.2 nT yr{sup -1} change in the radial heliospheric field at 1 AU, indicating that the mechanism is important to the heliospheric flux balance.

  9. Open Access: "à consommer avec modération"

    NASA Astrophysics Data System (ADS)

    Mahoney, Terence J.

    There is increasing pressure on academics and researchers to publish the results of their investigations in open access journals. Indeed, some funding agencies make open access publishing a basic requirement for funding projects, and the EU is considering taking firm steps in this direction. I argue that astronomy is already one of the most open of disciplines, and that access - both to the general public (in terms of a significantly growing outreach effort) and to developing countries (through efforts to provide computing facilities and Internet access, as well as schemes to provide research centres of limited resources with journals) - is becoming more and more open in a genuine and lasting way. I further argue that sudden switches to more formal kinds of open access schemes could cause irreparable harm to astronomical publishing. Several of the most prestigious astronomical research journals (e.g. MN, ApJ, AJ) have for more than a century met the publishing needs of the research community and continue to adapt successfully to changing demands on the part of that community. The after-effects of abrupt changes in publishing practices - implemented through primarily political concerns - are hard to predict and could be severely damaging. I conclude that open access, in its current acceptation, should be studied with great care and with sufficient time before any consideration is given to its implementation. If forced on the publishing and research communities, open access could well result in much more limited access to properly vetted research results.

  10. Benefits of Openness for US Security

    NASA Astrophysics Data System (ADS)

    May, Michael M.

    2000-04-01

    The US has been very successful in applying science and engineering to defense and space. The US has also run the most open defense research and development establishment in the world. The openness is connected with the success by making possible open criticism of mistakes and failures, access of foreign-born citizens, and participation of cleared scientists and engineers in open science around the world. This open system is at risk today, when it is more badly needed than ever. The right strategy is first, to draw a clear line around the information that should be kept secret, with some margin so that this information would not be partially given away by its boundary, and to continue with the open system elsewhere. The US, because it invests more, usually profits more from common knowledge. Second, spies are caught through good line leadership and good security work. The constraints now being discussed on unclassified information or on foreign visitors would not have helped catch them. Third, new guidance is needed for exports control. The US must cooperate with countries that are partners in trade and in international initiatives of the first importance, but which may also be political, economic and military rivals. Guidelines to protect what is key to our current military edge while retaining the open system are suggested.

  12. Perturbative approach to Markovian open quantum systems

    PubMed Central

    Li, Andy C. Y.; Petruccione, F.; Koch, Jens

    2014-01-01

    The exact treatment of Markovian open quantum systems, when based on numerical diagonalization of the Liouville super-operator or averaging over quantum trajectories, is severely limited by Hilbert space size. Perturbation theory, standard in the investigation of closed quantum systems, has remained much less developed for open quantum systems where a direct application to the Lindblad master equation is desirable. We present such a perturbative treatment which will be useful for an analytical understanding of open quantum systems and for numerical calculation of system observables which would otherwise be impractical.

  13. Open Surgical Approaches for Pulmonary Metastasectomy.

    PubMed

    Downey, Robert J; Bains, Manjit S

    2016-02-01

    Surgeons differ in the approach to resection of pulmonary metastases from nonpulmonary primary malignancies, with some favoring procedures that minimize trauma to the patient, and others performing open procedures with the goal of maximizing likelihood of resection of all detectable sites of disease. This article reviews how pulmonary metastasectomy emerged as a therapy for metastatic disease. Discussed is how surgical approaches used for this procedure have evolved, the available literature addressing whether open procedures lead to more complete resections, and if so whether resection by open procedures increases the likelihood of cure following resection. The technical aspects of the various thoracotomy techniques are also reviewed. PMID:26611506

  14. A flexible Open Data Assimilation framework

    Accurate and reliable real-time hydrological forecasts are essential for protection against water-related hazards, operation of infrastructure, and water resources management. Recent advances in radar rainfall estimation and forecasting, numerical weather predictions, satellite and in-situ monitoring, and faster computing facilities are opening up new opportunities in real-time hydrological forecasting. More effective use of the different information sources via data assimilation will provide the basis for producing more accurate and more reliable forecasts. In this regard, development and implementation of robust and computationally efficient data assimilation algorithms that are feasible for real-time applications remains one of the key challenges. The implementation of data assimilation techniques is traditionally in a model specific form. The disadvantage of this approach is the need to have in-depth knowledge of the numerical core computations and it does not allow to freely experiment with data assimilation algorithms and measurement sources without the need of additional programming. We present a more flexible approach to setup a forecasting system. The OpenDA data assimilation framework contains many state of the art data assimilation algorithms to easily set up a forecasting system. The setup of the framework allows users to select and experiment with various algorithms. OpenDA defines an interface between model and data assimilation algorithms. This interface only needs to be implemented once for a particular model. The OpenDA model interface is already implemented for various models. Besides these models it is very easy to couple models that are already implementing the Open Model Interface (OpenMI) to OpenDA using the generic OpenMI-OpenDA coupler. Using a synthetic test case we demonstrate the capabilities of the proposed approach using OpenMI and OpenDA. We use the MIKE SHE distributed and integrated hydrological modeling system to demonstrate how various ensemble based algorithms can be used to improve the forecasted groundwater level and river discharges. Biases in the measurements are detected and corrected by the generic bias correction module of OpenDA and spurious correlations are handled using both heuristic as automatic localization strategies.

  15. Transient features of quantum open maps.

    PubMed

    Ermann, Leonardo; Carlo, Gabriel G; Pedrosa, Juan M; Saraceno, Marcos

    2012-06-01

    We study families of open chaotic maps that classically share the same asymptotic properties--forward and backward trapped sets, repeller dimensions, and escape rate--but differ in their short time behavior. When these maps are quantized we find that the fine details of the distribution of resonances and the corresponding eigenfunctions are sensitive to the initial shape and size of the openings. We study phase space localization of the resonances with respect to the repeller and find strong delocalization effects when the area of the openings is smaller than ?. PMID:23005193

    Boker, Steven; Neale, Michael; Maes, Hermine; Wilde, Michael; Spiegel, Michael; Brick, Timothy; Spies, Jeffrey; Estabrook, Ryne; Kenny, Sarah; Bates, Timothy; Mehta, Paras; Fox, John

    2012-01-01

    OpenMx is free, full–featured, open source, structural equation modeling (SEM) software. OpenMx runs within the R statistical programming environment on Windows, Mac OS–X, and Linux computers. The rationale for developing OpenMx is discussed along with the philosophy behind the user interface. The OpenMx data structures are introduced — these novel structures define the user interface framework and provide new opportunities for model specification. Two short example scripts for the specification and fitting of a confirmatory factor model are next presented. We end with an abbreviated list of modeling applications available in OpenMx 1.0 and a discussion of directions for future development. PMID:23258944

  20. Oligomerized Pool ENgineering (OPEN): An “Open-Source” Protocol for Making Customized Zinc Finger Arrays

    Maeder, Morgan L.; Thibodeau-Beganny, Stacey; Sander, Jeffry D.; Voytas, Daniel F.; Joung, J. Keith

    2009-01-01

    Engineered zinc finger nucleases (ZFNs) form the basis of a broadly applicable method for targeted, efficient modification of eukaryotic genomes. In recent work, we described OPEN (Oligomerized Pool ENgineering), an “open-source,” combinatorial selection-based method for engineering zinc finger arrays that function well as ZFNs. We have also shown in direct comparisons that the OPEN method has a higher success rate than previously described “modular assembly” methods for engineering ZFNs. OPEN selections are performed in E. coli using a bacterial two-hybrid system and do not require specialized equipment. Here we provide a detailed protocol for performing OPEN to engineer zinc finger arrays that have a high probability of functioning as ZFNs. Using OPEN, researchers can generate multiple customized ZFNs in approximately 8 weeks. PMID:19798082

  4. OPENING ADDRESS: Heterostructures in Semiconductors

    NASA Astrophysics Data System (ADS)

    Grimmeiss, Hermann G.

    1996-01-01

    Good morning, Gentlemen! On behalf of the Nobel Foundation, I should like to welcome you to the Nobel Symposium on "Heterostructures in Semiconductors". It gives me great pleasure to see so many colleagues and old friends from all over the world in the audience and, in particular, to bid welcome to our Nobel laureates, Prof. Esaki and Prof. von Klitzing. In front of a different audience I would now commend the scientific and technological importance of heterostructures in semiconductors and emphatically emphasise that heterostructures, as an important contribution to microelectronics and, hence, information technology, have changed societies all over the world. I would also mention that information technology is one of the most important global key industries which covers a wide field of important areas each of which bears its own character. Ever since the invention of the transistor, we have witnessed a fantastic growth in semiconductor technology, leading to more complex functions and higher densities of devices. This development would hardly be possible without an increasing understanding of semiconductor materials and new concepts in material growth techniques which allow the fabrication of previously unknown semiconductor structures. But here and today I will not do it because it would mean to carry coals to Newcastle. I will therefore not remind you that heterostructures were already suggested and discussed in detail a long time before proper technologies were available for the fabrication of such structures. Now, heterostructures are a foundation in science and part of our everyday life. Though this is certainly true, it is nevertheless fair to say that not all properties of heterostructures are yet understood and that further technologies have to be developed before a still better understanding is obtained. The organisers therefore hope that this symposium will contribute not only to improving our understanding of heterostructures but also to opening new perspectives for future applications. We are most grateful that you agreed with the special format of the symposium which clearly does not follow conven- tional conferences. Allow me to call your special attention once again to two main differences: The presentations are not review papers praising already achieved break-throughs but introductions to a list of open questions and issues for which our understanding is still unsatisfactory. To give such presentations requires courage and scientific integrity. I would like to thank all speakers now already for their willingness to cope with such a difficult task. We have allocated at least 50 minutes for discussion after each presentation not only for discussing the paper as such but, if possible, to find answers to the open questions. If one or several participants in the audience during the discussion think they can contribute to improving our understanding of heterostructures, they are invited to write their ideas up and, if the referees agree, we are more than happy to publish these ideas in the proceedings. We admit that the program is rather demanding. For that reason, we plan to have a break on Thursday afternoon by first going to Denmark and touring the Hamlet castle of Kronborg. We then sail back to Sweden and will be hosted by the Krapperup castle where we will have a candle-light dinner and thereafter a baroque music concert featuring the Concerto Copenhagen. All participants, observers, and accompanying spouses are invited and we hope you will all enjoy the excur- sion. The local organising committee acknowledges with pleasure the financial and all other support received from the Nobel Foundation and the Nobel Institute of Physics as well as the initial initiative taken by the chairman of the Nobel Com- mittee for Physics, Prof. Nordling, who was the first to suggest this Nobel Symposium on "Heterostructures in Semicon- ductors". Special thanks also to the members of the program committee who have been of inestimable value in putting together the program and suggesting speakers and pote

  12. Openness versus secrecy? Historical and historiographical remarks.

    PubMed

    Vermeir, Koen

    2012-06-01

    Traditional historiography of science has constructed secrecy in opposition to openness. In the first part of the paper, I will challenge this opposition. Openness and secrecy are often interlocked, impossible to take apart, and they might even reinforce each other. They should be understood as positive (instead of privative) categories that do not necessarily stand in opposition to each other. In the second part of this paper, I call for a historicization of the concepts of 'openness' and 'secrecy'. Focusing on the early modern period, I briefly introduce three kinds of secrecy that are difficult to analyse with a simple oppositional understanding of openness and secrecy. In particular, I focus on secrecy in relation to esoteric traditions, theatricality and allegory. PMID:23050366

  14. Open Boundary Conditions for Dissipative MHD

    SciTech Connect

    Meier, E T

    2011-11-10

    In modeling magnetic confinement, astrophysics, and plasma propulsion, representing the entire physical domain is often difficult or impossible, and artificial, or 'open' boundaries are appropriate. A novel open boundary condition (BC) for dissipative MHD, called Lacuna-based open BC (LOBC), is presented. LOBC, based on the idea of lacuna-based truncation originally presented by V.S. Ryaben'kii and S.V. Tsynkov, provide truncation with low numerical noise and minimal reflections. For hyperbolic systems, characteristic-based BC (CBC) exist for separating the solution into outgoing and incoming parts. In the hyperbolic-parabolic dissipative MHD system, such separation is not possible, and CBC are numerically unstable. LOBC are applied in dissipative MHD test problems including a translating FRC, and coaxial-electrode plasma acceleration. Solution quality is compared to solutions using CBC and zero-normal derivative BC. LOBC are a promising new open BC option for dissipative MHD.

    We have entered an open access publishing era. The impact and significance of open access is still under debate after two decades of evolution. Open access journals benefit researchers and the general public by promoting visibility, sharing and communicating. Non-mainstream journals should turn the challenge of open access into opportunity of presenting best research articles to the global readership. Open access journals need to optimize their business models to promote the healthy and continuous development. PMID:24822120

  11. Quantum Open-Closed Homotopy Algebra and String Field Theory

    2011-10-19

    We reformulate the algebraic structure of Zwiebach's quantum open-closed string field theory in terms of homotopy algebras. We call it the quantum open-closed homotopy algebra (QOCHA) which is the generalization of the open-closed homotopy algebra (OCHA) of Kajiura and Stasheff. The homotopy formulation reveals new insights about deformations of open string field theory by closed string backgrounds. In particular, deformations by Maurer Cartan elements of the quantum closed homotopy algebra define consistent quantum open string field theories.

  12. Growth Kinematics of Opening-Mode Fractures

    NASA Astrophysics Data System (ADS)

    Eichhubl, P.; Alzayer, Y.; Laubach, S.; Fall, A.

    2014-12-01

    Fracture aperture is a primary control on flow in fractured reservoirs of low matrix permeability including unconventional oil and gas reservoirs and most geothermal systems. Guided by principles of linear elastic fracture mechanics, fracture aperture is generally assumed to be a linear function of fracture length and elastic material properties. Natural opening-mode fractures with significant preserved aperture are observed in core and outcrop indicative of fracture opening strain accommodated by permanent solution-precipitation creep. Fracture opening may thus be decoupled from length growth if the material effectively weakens after initial elastic fracture growth by either non-elastic deformation processes or changes in elastic properties. To investigate the kinematics of fracture length and aperture growth, we reconstructed the opening history of three opening-mode fractures that are bridged by crack-seal quartz cement in Travis Peak Sandstone of the SFOT-1 well, East Texas. Similar crack-seal cement bridges had been interpreted to form by repeated incremental fracture opening and subsequent precipitation of quartz cement. We imaged crack-seal cement textures for bridges sampled at varying distance from the tips using scanning electron microscope cathodoluminescence, and determined the number and thickness of crack-seal cement increments as a function of position along the fracture length and height. Observed trends in increment number and thickness are consistent with an initial stage of fast fracture propagation relative to aperture growth, followed by a stage of slow propagation and pronounced aperture growth. Consistent with fluid inclusion observations indicative of fracture opening and propagation occurring over 30-40 m.y., we interpret the second phase of pronounced aperture growth to result from fracture opening strain accommodated by solution-precipitation creep and concurrent slow, possibly subcritical, fracture propagation. Similar deformation mechanisms are envisioned to govern fracture growth over shorter timescales in reactive chemical subsurface environments including CO2 reservoirs, organic-rich shales, and geothermal systems.

  17. The Invariance of Open Solar Magnetic Flux

    NASA Astrophysics Data System (ADS)

    Smith, E. J.; Zhou, X.

    2005-12-01

    A major finding of Ulysses has been the relative invariance of the open magnetic flux transported into the heliosphere from the Sun by the solar wind. The measure of open flux, r- squared Br, where r is heliocentric distance and Br is the radial field component, was found to be independent of both heliolatitude and phase of the solar cycle, being essentially the same (to within much less than a factor of two) at the recent sunspot minimum and maximum (cycle #23). Although such an invariance is generally not a feature of models of the solar-heliospheric field, it was predicted by L. Fisk and N. Schwadron who proposed that newly created open flux is the result of merging of already open flux with adjacent magnetic loops so that reconnecting field lines result in another open field and another loop with the total number of each unchanged. Thus, studying the open flux in the solar wind is a test of this hypothesis. The preceding study of open flux by Smith and Balogh ended shortly after solar maximum in 2001 when the polar cap magnetic fields had just reversed and were still relatively weak. Since then, the polar cap fields have strengthened and are now about one-half their value during the previous two sunspot cycles (#21, 22). We now present further evidence regarding this important question in Ulysses data acquired over the past 4 years. The radial components at Ulysses and in-ecliptic spacecraft are compared since the latter measurements are potentially a measure of open flux extending back to previous sunspot cycles.

  18. Flow distances on open flow networks

    2015-11-01

    An open flow network is a weighted directed graph with a source and a sink, depicting flux distributions on networks in the steady state mode of an open flow system. Energetic food webs, economic input-output networks, and international trade networks are open flow network models of energy flows between species, money or value flows between industrial sectors, and goods flows between countries, respectively. An open flow network is different from a closed flow network because it considers the flows from or to the environment (the source and the sink). For instance, in energetic food webs, species obtain energy not only from other species but also from the environment (sunlight), and species also dissipate energy to the environment. Flow distances between any two nodes i and j are defined as the average number of transition steps of a random walker along the network from i to j. The conventional method for the calculation of the random walk distance on closed flow networks cannot be applied to open flow networks. Therefore, we derive novel explicit expressions for flow distances of open flow networks according to their underlying Markov matrix of the network in this paper. We apply flow distances to two types of empirical open flow networks, including energetic food webs and economic input-output networks. In energetic food webs, we visualize the trophic level of each species and compare flow distances with other distance metrics on the graph. In economic input-output networks, we rank sectors according to their average flow distances and cluster sectors into different industrial groups with strong connections. Other potential applications and mathematical properties are also discussed. To summarize, flow distance is a useful and powerful tool to study open flow systems.

  20. Some open questions in hydrodynamics

    Mateusz Dyndal; Laurent Schoeffel

    2014-12-16

    When speaking of unsolved problems in physics, this is surprising at first glance to discuss the case of fluid mechanics. However, there are many deep open questions that come with the theory of fluid mechanics. In this paper, we discuss some of them that we classify in two categories, the long term behavior of solutions of equations of hydrodynamics and the definition of initial (boundary) conditions. The first set of questions come with the non-relativistic theory based on the Navier-Stokes equations. Starting from smooth initial conditions, the purpose is to understand if solutions of Navier-Stokes equations remain smooth with the time evolution. Existence for just a finite time would imply the evolution of finite time singularities, which would have a major influence on the development of turbulent phenomena. The second set of questions come with the relativistic theory of hydrodynamics. There is an accumulating evidence that this theory may be relevant for the description of the medium created in high energy heavy-ion collisions. However, this is not clear that the fundamental hypotheses of hydrodynamics are valid in this context. Also, the determination of initial conditions remains questionable. The purpose of this paper is to explore some ideas related to these questions, both in the non-relativistic and relativistic limits of fluid mechanics. We believe that these ideas do not concern only the theory side but can also be useful for interpreting results from experimental measurements.

  1. Secrecy versus Openness: Historical Perspectives

    2014-03-01

    ``I think all members of the laboratory are agreed that the work which is being pursued here is of such importance that we should not like to see it or any part of it fall into private or foreign hands,'' J. Robert Oppenheimer announced to his colleagues at Los Alamos on November 15, 1943, putting the first formal secrecy policies into effect-while promising ``to make the procedure as little burdensome as possible, and to reduce its interference with the actual prosecution of the work.'' ``After the war, the question of secrecy was reconsidered... but the practice of classification continued; it was our `security,' whether it worked or failed,'' Oppenheimer's colleague Edward Teller updated us in 1981, halfway between the mimeographed handout of 1943 and the labyrinthine security policies of today. ``We now have millions of classified technical documents,'' Teller continued, and ``the limitations we impose on ourselves by restricting information are far greater than any advantage others could gain.'' Teller titled his critique ``The Road to Nowhere.'' Is there a road back? In some notable cases (digital computing, satellite reconnaissance, GPS) we have taken the road to openness, and Teller's opinion, at least in this domain, appears to have been correct.

  2. An open tubular ion chromatograph.

    Yang, Bingcheng; Zhang, Min; Kanyanee, Tinakorn; Stamos, Brian N; Dasgupta, Purnendu K

    2014-12-01

    We describe an open tubular ion chromatograph (OTIC) that uses anion exchange latex coated 5 ?m radius silica and 9.8 ?m radius poly(methyl methacrylate) tubes and automated time/pressure based hydrodynamic injection for pL-nL scale injections. It is routinely possible to generate 50,000 plates or more (up to 150,000 plates/m, columns between 0.3 and 0.8 m have been used), and as such, fast separations are possible, comparable to or in some cases better than the current practice of IC. With an optimized admittance detector, nonsuppressed detection permits LODs of submicromolar to double digit micromolar for a variety of analytes. However, large volume injections are possible and can significantly improve on this. A variety of eluents, the use of organic modifiers, and variations of eluent pH can be used to tailor a given separation. The approach is discussed in the context of extraterrestrial exploration, especially Mars, where the existence of large amounts of perchlorate in the soil needs to be confirmed. These columns can survive drying and freezing, and small footprint, low power consumption, and simplicity make OTIC a good candidate for such a mission. PMID:25394230

  9. Heterogeneous compute in computer vision: OpenCL in OpenCV

    2014-02-01

    We explore the relevance of Heterogeneous System Architecture (HSA) in Computer Vision, both as a long term vision, and as a near term emerging reality via the recently ratified OpenCL 2.0 Khronos standard. After a brief review of OpenCL 1.2 and 2.0, including HSA features such as Shared Virtual Memory (SVM) and platform atomics, we identify what genres of Computer Vision workloads stand to benefit by leveraging those features, and we suggest a new mental framework that replaces GPU compute with hybrid HSA APU compute. As a case in point, we discuss, in some detail, popular object recognition algorithms (part-based models), emphasizing the interplay and concurrent collaboration between the GPU and CPU. We conclude by describing how OpenCL has been incorporated in OpenCV, a popular open source computer vision library, emphasizing recent work on the Transparent API, to appear in OpenCV 3.0, which unifies the native CPU and OpenCL execution paths under a single API, allowing the same code to execute either on CPU or on a OpenCL enabled device, without even recompiling.

    2015-01-01

    Open flow network is a weighted directed graph with a source and a sink, depicting flux distributions on networks in the steady state of an open flow system. Energetic food webs, economic input-output networks, and international trade networks, are open flow network models of energy flows between species, money or value flows between industrial sectors, and goods flows between countries, respectively. Flow distances (first-passage or total) between any given two nodes $i$ and $j$ are defined as the average number of transition steps of a random walker along the network from $i$ to $j$ under some conditions. They apparently deviate from the conventional random walk distance on a closed directed graph because they consider the openness of the flow network. Flow distances are explicitly expressed by underlying Markov matrix of a flow system in this paper. With this novel theoretical conception, we can visualize open flow networks, calculating centrality of each node, and clustering nodes into groups. We apply fl...

  16. Relaxation of spheromak configurations with open flux

    SciTech Connect

    Garcia-Martinez, Pablo Luis; Farengo, Ricardo

    2009-11-15

    The relaxation of several kink unstable equilibria with open flux representative of spheromaks sustained by dc helicity injection is studied by means of three-dimensional, resistive magnetohydrodynamic simulations. No external driving is applied, but the initial conditions are chosen to reproduce the current profiles existing in a gun driven spheromak, which has a high current density in the open flux region and a low current density in the closed flux region. The growth and nonlinear saturation of various unstable modes, the dynamo action which converts toroidal flux into poloidal flux, and the evolution of the {lambda} profile ({lambda}={mu}{sub 0}J{center_dot}B/B{sup 2}) are studied. An initial condition is found which results in a dynamo that produces enough poloidal flux to compensate the resistive losses occurred during a characteristic time of the instability. The flux amplification factor around which this case oscillates is consistent with existing experimental data. During the relaxation, the central open flux tube develops a helical distortion and the closed flux surfaces are destroyed. After the relaxation event, close flux surfaces form again but the final profiles are not fully relaxed and the central open flux tube remains distorted. The effect of the Lundquist number on the evolution and its impact on the required level of fluctuations are evaluated. Finally, the dynamics of the system for different current levels in the open flux region is studied.

    Objective To highlight the role of open stone surgery in the management of urolithiasis in the current era of minimally invasive therapies. The introduction and continuous development of extracorporeal shockwave lithotripsy (ESWL), ureterorenoscopy and percutaneous nephrolithotomy (PCNL) over the past 30 years have led to a significant change in the current management of urolithiasis, where the indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. Methods We reviewed the most recent guidelines published by the European Association of Urology and the American Urological Association, and reviewed reports through a MEDLINE search to identify the indications and current role of open stone surgery. Results From the MEDLINE search, it was obvious that the number of papers published on open renal stone surgery has decreased during the last three decades, soon after the introduction of ESWL and PCNL. Conclusion Although currently most patients with stones can be managed by minimally invasive therapy, we believe that open surgery still has a role, and therefore it is of great importance to recognise that a small group of patients with complex stone disease, and those with anatomical and physiological anomalies, will benefit from this treatment option.

  19. Method for making generally cylindrical underground openings

    DOEpatents

    Routh, J.W.

    1983-05-26

    A rapid, economical and safe method for making a generally cylindrical underground opening such as a shaft or a tunnel is described. A borehole is formed along the approximate center line of where it is desired to make the underground opening. The borehole is loaded with an explodable material and the explodable material is detonated. An enlarged cavity is formed by the explosive action of the detonated explodable material forcing outward and compacting the original walls of the borehole. The enlarged cavity may be increased in size by loading it with a second explodable material, and detonating the second explodable material. The process may be repeated as required until the desired underground opening is made. The explodable material used in the method may be free-flowing, and it may be contained in a pipe.

    Significant technical advances in imaging, molecular biology and genomics have fueled a revolution in cell biology, in that the molecular and structural processes of the cell are now visualized and measured routinely. Driving much of this recent development has been the advent of computational tools for the acquisition, visualization, analysis and dissemination of these datasets. These tools collectively make up a new subfield of computational biology called bioimage informatics, which is facilitated by open source approaches. We discuss why open source tools for image informatics in cell biology are needed, some of the key general attributes of what make an open source imaging application successful, and point to opportunities for further operability that should greatly accelerate future cell biology discovery.

  2. Advanced emergency openings for commercial aircraft

    NASA Technical Reports Server (NTRS)

    Bement, L. J.; Schimmel, M. L.

    1985-01-01

    Explosively actuated openings in composite panels are proposed to enhance passenger survivability within commercial aircraft by providing improvements in emergency openings, fuselage venting, and fuel dump. The concept is to embed a tiny, highly stable explosive cord in the periphery of a load-carrying composite panel; on initiation of the cord, the panel is fractured to create a well-defined opening. The panel would be installed in the sides of the fuselage for passenger egress, in the top of the fuselage for smoke venting, and in the bottoms of the fuel cells for fuel dump. Described are the concerns with the use of explosive systems, safety improvements, advantages, experimental results, and recommended approach to gain acceptance and develop this concept.

  3. Do open access data policies inhibit innovation?

    USGS Publications Warehouse

    Katzner, Todd Eli

    2015-01-01

    There has been a great deal of attention paid recently to the idea of data sharing (Van Noorden 2014, Beardsley 2015, Nature Publishing Group2015, www.copdess.com). However, the vast majority of these arguments are in agreement and present as fait accompli the idea that data are a public good and that therefore, once published, they should become open access. In fact, although there are many good reasons for data sharing, there also are a number of cogent and coherent cases to be made against open-access policies (e.g., Fenichel and Skelly 2015). The goal of this piece is not to debate the relevance or accuracy of the points made in favor of data sharing but to elevate the discussion by pointing out key problems with open-access policies and to identify central issues that, if solved, will enhance the utility of data sharing to science and society.

  4. Hydraulically controlled discrete sampling from open boreholes

    USGS Publications Warehouse

    Harte, Philip T.

    2013-01-01

    Groundwater sampling from open boreholes in fractured-rock aquifers is particularly challenging because of mixing and dilution of fluid within the borehole from multiple fractures. This note presents an alternative to traditional sampling in open boreholes with packer assemblies. The alternative system called ZONFLO (zonal flow) is based on hydraulic control of borehole flow conditions. Fluid from discrete fractures zones are hydraulically isolated allowing for the collection of representative samples. In rough-faced open boreholes and formations with less competent rock, hydraulic containment may offer an attractive alternative to physical containment with packers. Preliminary test results indicate a discrete zone can be effectively hydraulically isolated from other zones within a borehole for the purpose of groundwater sampling using this new method.

    2015-01-01

    While hip arthroscopy grows in popularity, there are still many circumstances under which open hip preservation is the most appropriately indicated. This article specifically reviews open hip preservation procedures for a variety of hip conditions. Femoral acetabular impingement may be corrected using an open surgical hip dislocation. Acetabular dysplasia may be corrected using a periacetabular osteotomy. Acetabular protrusio may require surgical hip dislocation with rim trimming and a possible valgus intertrochanteric osteotomy. Legg–Calve–Perthes disease produces complex deformities that may be better served with osteotomies of the proximal femur and/or acetabulum. Chronic slipped capital femoral epiphysis may also benefit from a surgical hip dislocation and/or proximal femoral osteotomy. PMID:26649292

    Geostationary and sunsynchronous satellite data and in-situ observations from ship cruises are used to investigate the formation of open cellular structure in marine stratocumulus clouds over the Southeast Pacific (SEP). Open cellular convection either forms spontaneously as pockets of open cells (POCs) within overcast stratocumulus, or is advected into the region from midlatitude regions. POC formation occurs most frequently during the latter part of the night demonstrating that this transition is not caused by solar absorption-driven decoupling. The transition preferentially occurs in clouds with low 11-3.7 microns nighttime brightness temperature difference (BTD) which is found to be well correlated with both in-situ measured accumulation mode aerosol concentration and cloud droplet concentration estimates derived from MODIS. Besides indicating that night time BTD is an excellent proxy for stratocumulus cloud droplet concentration Nd, this also suggests that low aerosol concentrations favor POC formation. Indeed, extremely low accumulation mode aerosol concentrations are found during the passage of open cell events over the ship. Free-tropospheric moisture is not found to be an important factor in POC formation. Significant subseasonal variability occurs in the fractional coverage of open cellular convection over the broader SEP. This coverage is well correlated with a MODIS-derived drizzle proxy (MDP) proportional to the ratio of liquid water path (LWP) to Nd for predominantly overcast regions. Both LWP and Nd variability influences the MDP. Periods of low MDP have significant positive large scale Nd anomalies and are preceded byoffshore winds at 850 hPa, which suggests a potential continental influence upon open cell formation over the SEP. Together, the results suggest important two-way interactions between aerosols and drizzle in marine stratocumulus and a role for drizzle in modulating the large scale albedo of these cloud systems.

    True open access to scientific publications not only gives readers the possibility to read articles without paying subscription, but also makes the material available for automated ingestion and harvesting by 3rd parties. Once articles and associated data become universally treatable as computable objects, openly available to 3rd party aggregators and value-added services, what new services can we expect, and how will they change the way that researchers interact with their scholarly communications infrastructure? I will discuss straightforward applications of existing ideas and services, including citation analysis, collaborative filtering, external database linkages, interoperability, and other forms of automated markup, and speculate on the sociology of the next generation of users.

  11. Simulation of plasma erosion opening switches

    1988-01-01

    Recent progress in the modeling of Plasma Erosion Opening Switches is reviewed, and new results from both fluid and particle simulation compared. Three-fluid simulations with the ANTHEM code for switches on the NRL GAMBLE I machine and SNL PBFA II machine have shown strong dependence of the opening dynamics on the anode structure, the threshold for electron emission, on the possible presence of anomalous resistivity, and on advection of the magnetic field with cathode emitted electrons. Simulations with the implicit particle-in-cell code ISIS confirm these observations, but manifest broader current channels---in better agreement with GAMBLE I experimental results. 7 refs., 3 figs.

    2015-11-01

    Distal humerus fractures are challenging injuries for the upper extremity surgeon. However, recent techniques in open reduction internal fixation have been powerful tools in getting positive outcomes. To get such results, the surgeon must be aware of how to properly use these techniques in their respective practices. The method of fixation depends on the fracture, taking the degree of comminution and the restoration of the columns and articular surface into account. This article helps surgeons understand the concepts behind open reduction internal fixation of the distal humerus and makes them aware of pitfalls that may lead to negative results. PMID:26498548

    A simple model for open quantum systems is analyzed with Random Matrix Theory. The system is coupled to the continuum in a minimal way. In this paper we see the effect of opening the system on the level statistics, in particular the $\\Delta_3(L)$ statistic, width distribution and level spacing are examined as a function of the strength of this coupling. A super-radiant transition is observed, and it is seen that as it is formed, the level spacing and $\\Delta_3(L)$ statistic exhibit the signatures of missed levels.

    The phenylsulfonylethylidene (PSE) acetal is a relatively new protecting group in carbohydrate chemistry. However, carbohydrate-derived phenylsulfonylethylidene (PSE) acetals show a different behavior in reductive desulfonylation than simple symmetrical acetals. Here we have investigated various SET-type reaction conditions in order to open PSE acetals regioselectively and to produce chiral ?-hydroxyethenyl ethers. Whereas sodium amalgam leads to a mixture of regioisomeric vinyl ethers besides the ethylidene acetal, samarium iodide is suited for regioselective ring opening. This is shown with seven different carbohydrate PSE acetals, both of the 1,3-dioxane and the 1,3-dioxolane type. PMID:26469209

  18. The combinatorial formula for open gravitational descendents

    In recent works, [20],[21], descendent integrals on the moduli space of Riemann surfaces with boundary were defined. It was conjectured in [20] that the generating function of these integrals satisfies the open KdV equations. In this paper we develop the notions of symmetric Strebel-Jenkins differentials and of Kasteleyn orientations for graphs embedded in open surfaces. In addition we write an explicit expression for the angular form of the sum of line bundles. Using these tools we prove a formula for the descendent integrals in terms of sums over weighted graphs. Based on this formula, the conjecture of [20] was proved in [5].

    The Open Terminology Services (OTS) project provides a common, well-specified mechanism to access terminological content in a vendor and platform neutral fashion. The project includes a freely available API specification and an open source reference implementation. The API specification derives from the OMG Lexicon Query Services interface specification as a foundation and defines mechanisms for browsing, querying and import terminological content. The Java-based reference implementation uses the Lightweight Directory Access Protocol (LDAP) for a back end, and provides a mechanism to query and distribute heterogeneous terminological content using a common format. The project includes the CTS (Central Terminology Services) subset under HL7. PMID:14728514
