    For the past decade, most large-scale hydro development projects in northern Quebec have been put on hold due to land disputes with First Nations. Hydroelectric projects have recently been revived following an agreement signed with Aboriginal communities in the province who recognized the need to find new sources of revenue for future generations. Many Cree are working on the project to harness the waters of the Eastmain River located in the middle of their territory. The work involves building an 890 foot long dam, 30 dikes enclosing a 603 square-km reservoir, a spillway, and a power house with 3 generating units with a total capacity of 480 MW of power for start-up in 2007. The project will require the use of 2,400 workers in total. The Cree Construction and Development Company is working on relations between Quebec's 14,000 Crees and the James Bay Energy Corporation, the subsidiary of Hydro-Quebec which is developing the project. Approximately 10 per cent of the $735-million project has been designated for the environmental component. Inspectors ensure that the project complies fully with environmental protection guidelines. Total development costs for Eastmain-1 are in the order of $2 billion of which $735 million will cover work on site and the remainder will cover generating units, transportation and financial charges. Under the treaty known as the Peace of the Braves, signed in February 2002, the Quebec government and Hydro-Quebec will pay the Cree $70 million annually for 50 years for the right to exploit hydro, mining and forest resources within their territory. The project comes at a time when electricity export volumes to the New England states are down due to growth in Quebec's domestic demand. Hydropower is a renewable and non-polluting source of energy that is one of the most acceptable forms of energy where the Kyoto Protocol is concerned. It was emphasized that large-scale hydro-electric projects are needed to provide sufficient energy to meet both

    Because of the promised shutdown and decommissioning of the French Superphenix fast breeder reactor, the French research programs on transmutation will be reoriented towards the smaller Phenix reactor. This issue of 'DRN Actualites' brochure reports on the works carried out by the operator with the help of the Direction of Nuclear Reactors (DRN) of the CEA and Novatome company to satisfy the nuclear safety authorities requirements for the start-up of the Phenix reactor. Three aspects are developed: the 'Service life' project which concerns the non-destructive control of the reactor core and primary circuit, the seismic behaviour of the installation (diagnostic and reinforcement), and the renewal of the secondary circuit and steam generators.

    The revival of interest in Arctic natural gas and the developing competition to extend the pipeline grid to Alaska and the Yukon and the Northwest territories are the subject of this report. Substantial agreement between competing interest groups is reported with respect to the need for Arctic gas and the willingness of the market to pay for bringing it south to consumers. The discussion centers on the construction of the Alliance Pipeline Project that will reportedly bring two billion cubic feet per day of excess capacity to transport natural gas from northeastern British Columbia to Chicago, and the 2,400 km long Foothills Pipelines System that carries about one-third of Canadian gas exports to middle-western states and California. Plans are to extend the line to 5,240 km by laying pipe in a giant Y pattern between Prudhoe Bay and the Mackenzie delta in the north, and the start of the Foothills System at Caroline in central Alberta. The estimated cost of the line is about $US 6 billion, using a 36-inch diameter line at increased pressures in place of the 56-inch diameter pipe used in the 1970s. Construction plans are similar for the rest of the big Y, the Dempster Lateral beside the Dempster Highway between Whitehorse and Inuvik. A competing project, the Northern Gas Pipeline Project is also discussed. This line would run east of Prudhoe Bay under the Beaufort Sea to the Mackenzie Delta; then south along the Mackenzie Valley to Alberta. Cost of this line is also estimated at $US 6 billion, however, it would have a capacity of four billion cubic feet per day, including 2.5 billion cubic feet from Alaska and 1.5 billion cubic feet from Canada. Strong revival of interest is also reported from the supply side, with BP Amoco, ARCO, Chevron Canada Resources, Ranger 0il Ltd., Paramount Resources, Berkley Petroleum Corporation, Canadian Forest Oil, Alberta Energy Company, Petro-Canada, Anderson Resources, and Poco Petroleum Ltd., all showing interest to mount new

  4. Revival of the "Sun Festival": An educational and outreach project

    In ancient times, past civilisations used to celebrate both the winter and summer solstices, which represented key moments in the periodical cycle of seasons and agricultural activities. In 1904, the French astronomer Camille Flammarion, the engineer Gustave Eiffel, the science writer Wilfrid de Fonvielle and the Spanish astronomer Josep Comas i Solà decided to celebrate the summer solstice with a festival of science, art and astronomical observations opened to the public at the Eiffel tower in Paris. For ten consecutive years (1904-1914) on the day of the summer solstice, the "Sun Festival" (Fête du Soleil in French) included scientific and technological lectures and demostrations, celestial observations, music, poetry, danse, cinema, etc. This celebration was interrupted by the First World War, just to resume in Barcelona, Spain, between 1915 and 1937, and in Marseille, France, in the 1930s. It was the founders' dream to extend this celebration to all cities in France and elsewhere.It is only during the International Year of Astronomy in 2009, to our knowledge, that the "Sun Festival" was given another chance in France, thanks to the joint effort of several scientific and cultural centers (Centres de Culture Scientifique, Technique et Industrielle, CCSTI) and the timely support of the European Space Agency (ESA). In this occasion again, the festival was characterized by the combination of science, art and technological innovation around a common denominator: our Sun!We have recently revived the idea of celebrating the summer solstice with a "Sun Festival" dedicated to scientific education and outreach about our star and related topics. This project started last year in Aix-les-Bains, France, with the "Sun and Light Festival" (2015 was the International Year of Light), attended by about 100 people. This year's second edition was in Le Bourget-du-Lac, France. Following the COP21 event, the specific theme was the "Sun and Climate Festival", and we had about 250

    The first concrete of the nuclear island for the Jules Horowitz Reactor (JHR) was poured at the end of July 2009 and construction is ongoing. The JHR is the largest new platform for irradiation experiments supporting Generation II and III reactors, Generation IV technologies, and radioisotope production. This facility, composed of a unique grouping of workshops, hot cells and hot laboratories together with a first-rate MTR research reactor, will ensure that the process, from preparations for irradiation experiments through post-irradiation non-destructive examination, is completed expediently, efficiently and, of course, safely. In addition to the performance requirements to be met in terms of neutron fluxes on the samples (5x10 14 n.cm -2 /sec -1 E>1 MeV in core and 3,6x10 14 n.cm -2 /sec -1 E<0.625 eV in the reflector) and the JHR's considerable irradiation capabilities (more than 20 experiments and one-tenth of irradiation area for simultaneous radioisotope production), the JHR is the first MTR to be built since the end of the 1960s, making this an especially challenging project. The presentation will provide an overview of the reactor, hot cells and laboratories and an outline of the key milestones in the project schedule, including initial criticality in early 2014 and radioisotope production in 2015. This will be followed by a description of the project organization set up by the CEA as owner and future operator and AREVA TA as prime contractor and supplier of critical systems, and a discussion of project challenges, especially those dealing with the following items:accommodation of a broad experimental domain; involvement by international partners making in-kind contributions to the project; ? development of components critical to safety and performance; the revival of engineering of research reactors and experimental devices involving France's historical players in the field of research reactors, and; tools to carry out the project, including computer codes

  10. Save the Children, the humanitarian project, and the politics of solidarity: reviving Dorothy Buxton's vision.

    Science.gov (United States)

    Baughan, Emily; Fiori, Juliano

    2015-10-01

    This paper reflects on the foundational years of Save the Children, one of the oldest and largest Western humanitarian agencies and a mainstay of the humanitarian project. In doing so, it considers how and why, at an early stage, the organisation depoliticised its activities, centring its narrative on the innocent, pre-political child-the image of unsullied humanity. In addition, it seeks to recover the internationalist vision of Save the Children's 'forgotten founder', Dorothy Buxton. Save the Children's turn to non-politics is indicative of the broader depoliticisation of Western humanitarian action. Given the intensely contested spaces in which Western humanitarian non-governmental organisations (NGOs) operate, these entities cannot escape politics. This paper argues that Buxton's efforts to build an international solidarity network through humanitarian action after the end of the First World War in 1918 provide an instructive basis on which these NGOs can pursue a politics of solidarity in the present day. © 2015 The Author(s).

    2018-02-01

    A novel CO2 sequestration project at Wallula, Washington, USA, makes ample use of the geoscientific data collection of the old nuclear waste repository project at the Hanford Site nearby. Both projects target the Columbia River Basalt (CRB). The new publicity for the old project comes at a time when the approach to high-level nuclear waste disposal has undergone fundamental changes. The emphasis now is on a technical barrier that is chemically compatible with the host rock. In the ideal case, the waste container is in thermodynamic equilibrium with the host-rock groundwater regime. The CRB groundwater has what it takes to represent the ideal case.

    Quantum revivals are now a well-known phenomena within nonrelativistic quantum theory. In this Letter we display the effects of relativity on revivals and quantum carpets. It is generally believed that revivals do not occur within a relativistic regime. Here we show that while this is generally true, it is possible, in principle, to set up wave packets with specific mathematical properties that do exhibit exact revivals within a fully relativistic theory.

    The Halifax Regional Municipality (HRM) is the largest municipality in Atlantic Canada. This presentation described the flagship facility and the energy efficiency retrofit of five HRM-owned buildings called the Alderney 5 complex. The 5 objectives of the demonstration project involved a district-scale cooling project; replacement of chillers with harbour cooling; and replacement of a high exergy system with a low exergy system. Synergies and challenges of the project were also identified. The presentation also referred to borehole thermal energy storage; existing Halifax Harbour cooling; Halifax Harbour temperatures; cold energy geothermal borehole field; and the benefits of advanced concentric boreholes. A project update and progress to date were also provided. The Alderney 5 project represents the first concentric borehole technology for use to store and retrieve cold energy. tabs., figs.

  16. Quantum wave packet revivals

    International Nuclear Information System (INIS)

    Robinett, R.W.

    2004-01-01

    The numerical prediction, theoretical analysis, and experimental verification of the phenomenon of wave packet revivals in quantum systems has flourished over the last decade and a half. Quantum revivals are characterized by initially localized quantum states which have a short-term, quasi-classical time evolution, which then can spread significantly over several orbits, only to reform later in the form of a quantum revival in which the spreading reverses itself, the wave packet relocalizes, and the semi-classical periodicity is once again evident. Relocalization of the initial wave packet into a number of smaller copies of the initial packet ('minipackets' or 'clones') is also possible, giving rise to fractional revivals. Systems exhibiting such behavior are a fundamental realization of time-dependent interference phenomena for bound states with quantized energies in quantum mechanics and are therefore of wide interest in the physics and chemistry communities. We review the theoretical machinery of quantum wave packet construction leading to the existence of revivals and fractional revivals, in systems with one (or more) quantum number(s), as well as discussing how information on the classical period and revival time is encoded in the energy eigenvalue spectrum. We discuss a number of one-dimensional model systems which exhibit revival behavior, including the infinite well, the quantum bouncer, and others, as well as several two-dimensional integrable quantum billiard systems. Finally, we briefly review the experimental evidence for wave packet revivals in atomic, molecular, and other systems, and related revival phenomena in condensed matter and optical systems

  17. Death and revival of chaos.

    2016-12-01

    We investigate the death and revival of chaos under the impact of a monotonous time-dependent forcing that changes its strength with a non-negligible rate. Starting on a chaotic attractor it is found that the complexity of the dynamics remains very pronounced even when the driving amplitude has decayed to rather small values. When after the death of chaos the strength of the forcing is increased again with the same rate of change, chaos is found to revive but with a different history. This leads to the appearance of a hysteresis in the complexity of the dynamics. To characterize these dynamics, the concept of snapshot attractors is used, and the corresponding ensemble approach proves to be superior to a single trajectory description, that turns out to be nonrepresentative. The death (revival) of chaos is manifested in a drop (jump) of the standard deviation of one of the phase-space coordinates of the ensemble; the details of this chaos-nonchaos transition depend on the ratio of the characteristic times of the amplitude change and of the internal dynamics. It is demonstrated that chaos cannot die out as long as underlying transient chaos is present in the parameter space. As a condition for a "quasistatically slow" switch-off, we derive an inequality which cannot be fulfilled in practice over extended parameter ranges where transient chaos is present. These observations need to be taken into account when discussing the implications of "climate change scenarios" in any nonlinear dynamical system.

    2016-01-01

    This book primarily explores two topics: the representation of simultaneous, cooperative work processes in product development projects with the help of statistical models, and the assessment of their emergent complexity using a metric from theoretical physics (Effective Measure Complexity, EMC). It is intended to promote more effective management of development projects by shifting the focus from the structural complexity of the product being developed to the dynamic complexity of the development processes involved. The book is divided into four main parts, the first of which provides an introduction to vector autoregression models, periodic vector autoregression models and linear dynamical systems for modeling cooperative work in product development projects. The second part presents theoretical approaches for assessing complexity in the product development environment, while the third highlights and explains closed-form solutions for the complexity metric EMC for vector autoregression models and linear dyn...

    2003-12-01

    Ulysses contracts have faced paternalism objections since they first were proposed. Since the contracts are designed to override a present request from a legally competent patient in favor of a past request made by that patient, enforcement of these contracts was argued to be unjustifiable strong paternalism. Recent legal developments and new theories of practical reasoning suggest that the discussion of Ulysses contracts should be revived. This paper argues that with a proper understanding of the future-directed planning embodied in Ulysses contracts, the charge of strong paternalism can be answered, and the enforcement of some Ulysses contracts may be justified under the rubric of weak paternalism.

    A successful revival of the nuclear power industry will require standardization and a reduction in the number of companies managing construction, according to Atomic Industrial Forum spokesmen. In describing the concept of a few superutilities to build nuclear plants, they emphasize the need for a nuclear culture among construction management. Future plant designs emphasize small scale, with design, engineering, licensing, financing, operator training, and paperwork completed before the sale. Utilities continue to pursue economy-of-scale despite the evidence that small-scale reactors can be economical and are more appropriate for fluctuating demand growth. Financiers want more say in construction plans in the future, while utilities want to establish generating subsidiaries for wholesale power sales

    Full Text Available The art of tapestry has its basics back in time, probably in the decorations of tent, the house of the nomad. Tapestry in its beginnings is the first wall of the nomad’s home and the decorative wall and canopy in the ancient Greek houses as architect Gottfried Semper stated in the nineteen century. The architectural approach is not unusual even in the next centuries. Tapestry becomes popular as a form of monumental art during the Middle Ages when it is used as decorative architectural element, coating the walls of medieval castles. During the next centuries dominated by decadent styles of baroque, rococo, the tapestry will lose its monumental spirit and architectural quality but at the middle of the XXth century a new approach will sustain the revival of the tapestry as monumental art. Later, in the XXIst century, renowned multimedia artists will approach this medium and will use computer assisted looms in ambitious tapestry projects. This technique will allow them to realize complex and exquisite tapestries, sustaining in this way the revival of the tapestry in the contemporary art world. The paper presents the importance of the architectural side of tapestry and the great achievement that computer assisted loom represents for this form of art. The research activity is willing to inform Romanian textile designers about the possibilities to create tapestries on computer assisted looms. The research was made during the initial stage of a doctoral thesis consisting in a documentary study on monumental aspects of contemporary tapestry.

    2014-01-01

    This unique book that deals with project communication management in complex environments, taking a leaf from China’s experience with a major earthquake in Sichuan, would be a timely contribution to fill this lacuna. Readers would be able to understand how companies and organizations that are unprepared for crisis management would react to their detriment. The lessons provided in this book are the only one of its kind to highlight the lessons for companies and organizations to prepare themselves for successful project communication management through the complexity-informed framework. Although the book is written by two building professionals, the concepts and lessons presented are generic and equally applicable for businesses outside of the construction industry; for example, for airports, resorts, hotels, shipyards, etc.

  19. TOURISM AND CULTURAL REVIVAL

    Directory of Open Access Journals (Sweden)

    George NICULESCU

    2009-12-01

    Full Text Available This paper examines the tourism and the cultural revival. Cultural change is a recurrent concern in tourism studies. Host societies frequently remodel their culture following the creation of a tourist resort. But, that does not necessarily imply an acculturating process, since what actually takes place is pragmatic cultural production work in response to the touristic demands that offer consolidated economic alternatives and livelihood. Culture change has been a concern in tourism anthropology studies ever since this field of research established itself, particularly concerning the changes host societies undergo. But that does not necessarily imply the phenomenon is to be analyzed exclusively under the focus of the acculturation paradigm, since researchers often come across the production of new cultural elements of a traditional character among host populations in their attempt to occupy new spaces from which to address the world. in fact, that applies to various social situations where local actors seek to display certain lifestyles and cultural traits in order to draw attention to their ethnic, regional, or national features. Therefore, the object of study no longer focuses on the gradual loss of local and cultural (or ethnic substance, but rather on the relative ethnicity triggered by and among translocal flows that may lead to the deliberate turnaround of different cultural aspects of the host populations. Based on those premises, this article deals with the investigation of a cultural change process, making use of the historic perspective that includes an analysis of the “strategies of cultural mobilization” activated by the social subjects that are constantly recreating themselves in the tourism areas.

It is intended to serve as an introduction to the topical question of classification of holomorphic vector bundles on complex projective spaces, and can easily be read by students with a basic knowledge of analytic or algebraic geometry. Short supplementary sections describe more advanced topics, further results, and unsolved problems.

  1. Reviving Markov processes and applications

    International Nuclear Information System (INIS)

    Cai, H.

    1988-01-01

    In this dissertation we study a procedure which restarts a Markov process when the process is killed by some arbitrary multiplicative functional. The regenerative nature of this revival procedure is characterized through a Markov renewal equation. An interesting duality between the revival procedure and the classical killing operation is found. Under the condition that the multiplicative functional possesses an intensity, the generators of the revival process can be written down explicitly. An intimate connection is also found between the perturbation of the sample path of a Markov process and the perturbation of a generator (in Kato's sense). The applications of the theory include the study of the processes like piecewise-deterministic Markov process, virtual waiting time process and the first entrance decomposition (taboo probability)

    Wave packet revivals and fractional revivals are studied by means of a measure of nonclassicality based on the Fisher information. In particular, we show that the spreading and the regeneration of initially Gaussian wave packets in a quantum bouncer and in the infinite square-well correspond, respectively, to high and low nonclassicality values. This result is in accordance with the physical expectations that at a quantum revival wave packets almost recover their initial shape and the classical motion revives temporarily afterward.

    2007-07-01

    Europe and the U.S share an history of almost five decades of use of nuclear energy for electricity generation, and they still represent the bulk of it. However, new investments were almost totally stopped for many years, in the US first--essentially for economic reasons--and then in Europe, for more complex reasons, including the consequences of the Chernobyl accident. Today, there are clear signs of a nuclear revival on both sides of the Atlantic Ocean ; this paper deals with the drivers of this revival, the conditions to be satisfied for a transformation of these first signs into a real revival, the possible extent of it, and the consequences for the rest of the world.

    2001-01-01

    Low- and intermediate level radioactive waste, produced at Swedish nuclear power plants, will be deposited in an underground repository, SFR. Different substances in the waste or in degradation products emanating from the waste, and chemicals added during the building of cementitious barriers in the repository, may exhibit complexing properties. The complexation of radionuclides with such ligands may increase the mobility of the deposited radionuclides as sorption on the cement phases is decreased and solubility increased. This could lead to an increased leaching of the radionuclides from the repository to the geosphere and biosphere. To be able to evaluate the implications for the function and long-term safety of the repository a study has been performed on complexants in SFR. The study is a part of project SAFE (Safety Assessment of Final Repository for operational Radioactive Waste) at the Swedish Nuclear Fuel and Waste Management Co, SKB. Concentrations of complexants were calculated in different waste types in the repository and compared to critical levels above which radionuclide sorption may be affected. The analysis is based on recent research presented in international and national literature sources. The waste in SFR that may act or give rise to substances with complexing properties mainly consists of cellulose materials, including cement additives used in waste conditioning and backfill grout. The radioactive waste also contains chemicals mainly used in decontamination processes at the nuclear power plants, e.g. EDTA, NTA, gluconate, citric acid and oxalic acid. The calculations performed in this report show that the presence of complexants in SFR may lead to a sorption reduction for some radionuclides in certain waste types. This may have to be considered when performing calculations of the radionuclide transport. Concentration calculations of isosaccharinic acid (ISA), using a degradation yield of 0.1 mole/kg cellulose (2%), showed that the limit above

    2011-01-01

    Full Text Available We present a case of complex regional pain syndrome (CRPS, in which symptoms, including burning pain and severe allodynia, were alleviated by using a regional intravenous nerve blockade (Bier block combined with physiotherapy, but reappeared following an epileptic seizure. Symptoms disappeared again following control of epileptic discharges, as revealed by single-photon emission computed tomography (SPECT and electroencephalography (EEG results. Although systemic toxicity of a local anesthetic applied by Bier block was suspected as a cause of the first seizure, the patient did not present any other toxic symptoms, and seizures repeatedly occurred after Bier block cessation; the patient was then diagnosed as having temporal symptomatic epilepsy. This case suggests that symptoms of CRPS may be sustained by abnormal brain conditions, and our findings contribute to the understanding of how the central nervous system participates in maintaining pain and allodynia associated with CRPS.

In recent years, with the Fa11 of the Berlin Wall, political scientists and others, suchas A.D. Smith, Ernest Gellner, and E.J. Hobsbawm, have also focused on the subject of nationalism. The intention here in this article is to revisit a familiar site in the light of these new ideas and to test their validity or appropriateness in the Irish context. The article, part of a larger project to be published in 2003 by Polity Press under the title A Cultural History of Twentieth-Century Irish Literature, is divided into 5 sections: What ish my Nation?; What is a Nation?; Do Nations Have Navels?; 1890s: Winds of Change; English As We Speak It In Ireland.

    Mulenburg, Gerald M.; Impaeilla, Cliff (Technical Monitor)

    2000-01-01

    This paper reports on a research study by the author that examined ten contemporary National Aeronautics and Space Administration (NASA) complex projects. In-depth interviews with the project managers of these projects provided qualitative data about the inner workings of the project and the methodologies used in establishing and managing the projects. The inclusion of a variety of space, aeronautics, and ground based projects from several different NASA research centers helped to reduce potential bias in the findings toward any one type of project, or technical discipline. The findings address the participants and their individual approaches. The discussion includes possible implications for project managers of other large, complex, projects.

    Full Text Available More and more projects from different industrial sectors developed in transnational environment are becoming more characterized as "complex". In recent years, there has been much discussion and controversy about the complexity of the projects, and, despite what has been written and said in various papers, journals and professional conferences, more confusion than clarification was created, complexity of projects being interpreted differently from one author to another. Most of the literature studied is based on linear, analytical and rational approach, focusing on the size of project management planning and control and actually less on projects that are characterized as taking place and grow into a dynamic socio-human environment in a continuous change. This study represents a critical review of existing theoretical models found in literature, highlighting their limitations. The output of this literature study represents an integration of different approaches concerning complexity under one umbrella to provide a common understanding of the evolution of this concept.

    Full Text Available In this study, we propose a Bilateral Double Motive framework of stakeholder cooperation in complex projects. The framework analyses and explains dyadic promoter-stakeholder relationships at a micro level by acknowledging both transactional and relational motives. We demonstrate the framework’s usefulness by illustrating its explanatory power in two instances of cooperation and two of non-cooperation within two health information technology projects. The study contributes to project management theory through its combined focus on transactional and relational motives. Further, the study contributes to practice by providing a tool for planning and evaluating cooperation in health Information Technology projects and similar complex multi-stakeholder environments.

  3. Coal: a revival for France?

    International Nuclear Information System (INIS)

    Brones, W.

    2007-01-01

    All energy consumption forecasts indicate a world production peak of fossil fuels around 2030 followed by a rapid decline. The oil peak should probably occur earlier. In this context the huge worldwide reserves of coal represent a fantastic opportunity to meet the world power demand which should double between 2002 and 2030 with in particular a huge growth in China and India. If promising alternate technologies (coal liquefaction..) exist which would allow to replace petroleum by coal, the main question remains the management of CO 2 . Capture and sequestration techniques are already implemented and tested and the search for new coal deposits is going on, in particular in France in the Nievre area. Economic studies about the profitability of coal exploitation in France stress on the socio-economical advantage that a revival of this activity would represent, in particular in terms of employment.

    The sigma model on projective superspaces CP{sup S-1} {sup vertical} {sup stroke} {sup S} gives rise to a continuous family of interacting 2D conformal field theories which are parametrized by the curvature radius R and the theta angle {theta}. Our main goal is to determine the spectrum of the model, non-perturbatively as a function of both parameters. We succeed to do so for all open boundary conditions preserving the full global symmetry of the model. In string theory parlor, these correspond to volume filling branes that are equipped with a monopole line bundle and connection. The paper consists of two parts. In the first part, we approach the problem within the continuum formulation. Combining combinatorial arguments with perturbative studies and some simple free field calculations, we determine a closed formula for the partition function of the theory. This is then tested numerically in the second part. There we propose a spin chain regularization of the CP{sup S-1} {sup vertical} {sup stroke} {sup S} model with open boundary conditions and use it to determine the spectrum at the conformal fixed point. The numerical results are in remarkable agreement with the continuum analysis. (orig.)

  6. The Nuclear Power Revival in Eastern Europe

    International Nuclear Information System (INIS)

    Bayou, Celine

    2007-01-01

    Far from traumatized by the April 1986 Chernobyl accident, the Central and Eastern European countries as well as the CIS are showing a growing interest in nuclear energy: this choice may be explained by increased energy demands and safer supply requirements but also by the battle against global warming. In effect, commitments made on limiting greenhouse gas emissions (particularly for the EU new member states) are becoming increasingly important as these countries return to growth. Thus, nuclear power seems to be a partial but secure means of not endangering the latter while adopting a more respectful stance vis-a-vis the environment. Thus, each country is coming out in favour of the civilian use of nuclear power: Russia has been reviving its nuclear program over the last few years, while countries obliged to close their decrepit or Soviet style power stations (Bulgaria, Slovakia, Lithuania, Slovenia, Armenia) have projects to build new ones. Those who possess reactors (the Czech Republic, Hungary, Romania, the Ukraine) are endeavouring to increase their potential, those which had hitherto no civilian nuclear facilities are now planning to build them (Belarus, Albania) or are contributing to projects in neighbouring countries (Estonia, Latvia, Poland). Within this context, the anti-nuclear argument has difficulty in finding a voice in the East

  7. On Best Practices for Risk Management in Complex Projects

    2011-01-01

    Full Text Available Risk management shall be proactive. This is one of the key preliminaries to cope with the challenges of complex projects. An overarching and consistent view on project risks and uncertainties is necessary to follow a holistic approach in project risk management. Uncertainty is inevitable since projects are unique and temporary undertakings based on assumptions and constraints, delivering project results to multiple stakeholders with different requirements. Project management can be seen as an attempt to control this uncertain environment, through the use of structured and disciplined techniques such as estimating, planning, cost control, task allocation, earned value analysis, monitoring, and review meetings. Each of these elements of project management has a role in defining or controlling inherent variability in projects. Project risk management provides approaches by which uncertainty can be understood, assessed, and managed within projects. A number of associations (e.g., Project Management Institute – PMI®, International Project Management Association – IPMA,or Network of Nordic Project Management Associations - NORDNET work constantly in acquiring, improving, and standardizing best practices in project management.Based on the industrial practice, this paper outlines strategies to identify, prioritize, and mitigate risks for achievement of project’ or organizational objectives.

    This presentation discusses the project complexity determination process that was developed by National Security Technologies, LLC, for the U.S. Department of Energy, National Nuclear Security Administration Nevada Field Office for implementation at the Nevada National Security Site (NNSS). The complexity determination process was developed to address the diversity of NNSS project types, size, and complexity; to fill the need for one procedure but with provision for tailoring the level of rigor to the project type, size, and complexity; and to provide consistent, repeatable, effective application of project management processes across the enterprise; and to achieve higher levels of efficiency in project delivery. These needs are illustrated by the wide diversity of NNSS projects: Defense Experimentation, Global Security, weapons tests, military training areas, sensor development and testing, training in realistic environments, intelligence community support, sensor development, environmental restoration/waste management, and disposal of radioactive waste, among others.

The project aims at enhancing safety culture and nuclear safety by supporting high quality execution of complex projects in the nuclear industry. Safety-critical industries are facing new challenges, related to increased outsourcing and complexity in technology, work tasks and organizational structures (Milch and Laumann, 2016). In the nuclear industry, new build projects, as well as modernisation projects are temporary undertakings often carried out by networks of companies. Some companies may have little experience in the nuclear industry practices or consideration of specific national regulatory requirements. In large multinational subcontractor networks, the challenge for assuring nuclear safety arises partly from the need to ensure that safety and quality requirements are adequately understood and fulfilled by each partner. Deficient project management practices and unsatisfactory nuclear safety culture in project networks have been recognised as contributing factors to these challenges (INPO, 2010). Prior evidence indicated that many recent major projects have experienced schedule, quality and financial challenges both in the nuclear industry (STUK, 2011) and in the non-nuclear domain (Ahola et al., 2014; Brady and Davies, 2010). Since project delays and quality issues have been perceived mainly as economic problems, project management issues remain largely understudied in safety research. However, safety cannot be separated from other performance aspects if a systemic view is applied. Schedule and quality challenges may reflect deficiencies in coordination, knowledge and competence, distribution of roles and responsibilities or attitudes among the project participants. It is increasingly understood that the performance of the project network in all

    . Therefore, buying companies also need to influence supplier actors to prioritize and optimize resource flows into their specific exchange. Based on a theoretical basis comprising the literature on buyer-seller relationship, including resource based research of the Industrial Marketing and Purchasing (IMP......) group, as well as Dynamic Capabilities theory and the project management literature, this paper presents the results from a study of applied buying company resource mobilization routines. We report on a qualitative investigation of routines applied in complex construction projects in the North European...... offshore wind turbine industry. Complex construction/production projects are widespread global business phenomena, but knowledge of resource mobilization routines in this context is scarce in the literature. We find that the complex project owner (buying company) applies a series of 11 particular routines...

  13. Collapse and revival in holographic quenches

    International Nuclear Information System (INIS)

    Silva, Emilia da; Lopez, Esperanza; Mas, Javier; Serantes, Alexandre

    2015-01-01

    We study holographic models related to global quantum quenches in finite size systems. The holographic set up describes naturally a CFT, which we consider on a circle and a sphere. The enhanced symmetry of the conformal group on the circle motivates us to compare the evolution in both cases. Depending on the initial conditions, the dual geometry exhibits oscillations that we holographically interpret as revivals of the initial field theory state. On the sphere, this only happens when the energy density created by the quench is small compared to the system size. However on the circle considerably larger energy densities are compatible with revivals. Two different timescales emerge in this latter case. A collapse time, when the system appears to have dephased, and the revival time, when after rephasing the initial state is partially recovered. The ratio of these two times depends upon the initial conditions in a similar way to what is observed in some experimental setups exhibiting collapse and revivals.

  17. Wave-packet revivals for quantum systems with nondegenerate energies

    International Nuclear Information System (INIS)

    Bluhm, R.; Tudose, B.

    1996-01-01

    The revival structure of wave packets is examined for quantum systems having energies that depend on two nondegenerate quantum numbers. For such systems, the evolution of the wave packet is controlled by two classical periods and three revival times. These wave packets exhibit quantum beats in the initial motion as well as new types of long-term revivals. The issue of whether fractional revivals can form is addressed. We present an analytical proof showing that at certain times equal to rational fractions of the revival times the wave packet can reform as a sum of subsidiary waves and that both conventional and new types of fractional revivals can occur.

    Full Text Available This paper presents a case study on the endeavours taken by public institutions in Bihor County in order to revitalize tourism in Oradea. According to the official website of Oradea Municipality, there are several ongoing projects in 2015, most of them aimed at raising Oradea’s tourism at European standards. Projects which are currently in progress are focused, in particular, on developing the cultural and historic heritage (by conserving the history of places, buildings, customs and other works by men and valorising the geothermal resources of which it benefits. Most projects are carried out through the Regional Operational Programme 2007-2013, Priority Axes 1 ”Support to sustainable development of cities – urban growth poles” and 5 – ”Sustainable development and promotion of tourism”. Actually, the completion of these projects aims to diversify and improve tourism services in Oradea, on the one hand, by creating modern leisure services (of the Aqua park, Spa, Wellness type, and on the other hand, by rehabilitating and modernising the cultural and historical centre of Oradea (Piața Unirii [Union Square] and Vasile Alecsandri Street. Moreover, Oradea City App was created, available in Romanian and English, in order to provide the user with complex information both on tourist attractions, accommodation and catering establishments that are available in Oradea and Băile Felix, as well as on the possibilities for leisure (theatre, movies, concerts, fairs, exhibitions, sports facilities, etc.. This year also, on May 10, 2015, it was decided that a referendum will be held in order to request the territorial merger between Oradea and Sînmartin which would lead to ranking Oradea in the league of large cities. According to mayors Ilie Bolojan (Oradea and Lucian Popuș (Sînmartin “the purpose of this endeavour is the joint development of the two localities, by numeric increase of the population, in order to ensure economic development

    Full Text Available The "new" that makes the cults of the occult revival to "new religions" of the Western world, is their recently increased social significance. Historically most of modern occultism is anything but new. From the research and theorizing about the occult revival we have picked up some main themes. The first is the social diffusion of the new occultism. In this field, we find some studies of superstition, especially astrology. These illuminate the differences in social connotation between the consumers of superstition and the followers of institutional religion. Secondly the study of the occult revival has made valuable contributions to the conceptualizing of "cult" and the cultic phenomenon. Thirdly, we will look upon the connection between the occult revival and the counter-culture. The problem of the rise of cults as a symptom of socio-cultural change will be briefly discussed with reference to Bell's thesis of "the disjuntion of culture and social structure". Lastly, we proffer some reflections on the occult revival and the new spiritual trends in the churches, which so sharply contrast with the theology and churchmanship of the sixties.

A matrix-based risk propagation model is introduced to calculate risk propagation and thus to re-eva...

  1. A low complexity reweighted proportionate affine projection algorithm with memory and row action projection

    Science.gov (United States)

    Liu, Jianming; Grant, Steven L.; Benesty, Jacob

    2015-12-01

    A new reweighted proportionate affine projection algorithm (RPAPA) with memory and row action projection (MRAP) is proposed in this paper. The reweighted PAPA is derived from a family of sparseness measures, which demonstrate performance similar to mu-law and the l 0 norm PAPA but with lower computational complexity. The sparseness of the channel is taken into account to improve the performance for dispersive system identification. Meanwhile, the memory of the filter's coefficients is combined with row action projections (RAP) to significantly reduce computational complexity. Simulation results demonstrate that the proposed RPAPA MRAP algorithm outperforms both the affine projection algorithm (APA) and PAPA, and has performance similar to l 0 PAPA and mu-law PAPA, in terms of convergence speed and tracking ability. Meanwhile, the proposed RPAPA MRAP has much lower computational complexity than PAPA, mu-law PAPA, and l 0 PAPA, etc., which makes it very appealing for real-time implementation.

  2. Full revivals in 2D quantum walks

    2010-01-01

    Recurrence of a random walk is described by the Polya number. For quantum walks, recurrence is understood as the return of the walker to the origin, rather than the full revival of its quantum state. Localization for two-dimensional quantum walks is known to exist in the sense of non-vanishing probability distribution in the asymptotic limit. We show, on the example of the 2D Grover walk, that one can exploit the effect of localization to construct stationary solutions. Moreover, we find full revivals of a quantum state with a period of two steps. We prove that there cannot be longer cycles for a four-state quantum walk. Stationary states and revivals result from interference, which has no counterpart in classical random walks.

    Krueckl, Viktor; Kramer, Tobias

    2009-01-01

    We investigate the propagation of wave packets on graphene in a perpendicular magnetic field and the appearance of collapses and revivals in the time evolution of an initially localized wave packet. The wave-packet evolution in graphene differs drastically from the one in an electron gas and shows a rich revival structure similar to the dynamics of highly excited Rydberg states. We present a novel numerical wave-packet propagation scheme in order to solve the effective single-particle Dirac-Hamiltonian of graphene and show how the collapse and revival dynamics is affected by the presence of disorder. Our effective numerical method is of general interest for the solution of the Dirac equation in the presence of potentials and magnetic fields.

  5. A Project Management Approach to Using Simulation for Cost Estimation on Large, Complex Software Development Projects

    Science.gov (United States)

    Mizell, Carolyn; Malone, Linda

    2007-01-01

    It is very difficult for project managers to develop accurate cost and schedule estimates for large, complex software development projects. None of the approaches or tools available today can estimate the true cost of software with any high degree of accuracy early in a project. This paper provides an approach that utilizes a software development process simulation model that considers and conveys the level of uncertainty that exists when developing an initial estimate. A NASA project will be analyzed using simulation and data from the Software Engineering Laboratory to show the benefits of such an approach.

    We have studied the existence of quantum revivals in graphene quantum rings within a simplified model. The time evolution of a Gaussian-populated wavepacket shows revivals in monolayer and bilayer graphene rings. We have also studied this behavior for quantum rings in a perpendicular magnetic field. We have found that revival time is an observable that shows different values for monolayer and bilayer graphene quantum rings. In addition, the revival time shows valley degeneracy breaking.

    Revivals of the coherent states of a deformed, adiabatically and cyclically varying oscillator Hamiltonian are examined. The revival time distribution is exactly that of Poincare recurrences for a rotation map: only three distinct revival times can occur, with specified weights. A link is thus established between quantum revivals and recurrences in a coarse-grained discrete-time dynamical system. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Zhang Fang-Fang; Liu Shu-Tang; Yu Wei-Yong

    2013-01-01

    To increase the variety and security of communication, we present the definitions of modified projective synchronization with complex scaling factors (CMPS) of real chaotic systems and complex chaotic systems, where complex scaling factors establish a link between real chaos and complex chaos. Considering all situations of unknown parameters and pseudo-gradient condition, we design adaptive CMPS schemes based on the speed-gradient method for the real drive chaotic system and complex response chaotic system and for the complex drive chaotic system and the real response chaotic system, respectively. The convergence factors and dynamical control strength are added to regulate the convergence speed and increase robustness. Numerical simulations verify the feasibility and effectiveness of the presented schemes. (general)

    Using a generic Hamiltonian that models wave packet propagation in a Kerr-like medium, matter wave field dynamics in Bose-Einstein condensation, etc., we show that distinctive signatures of wave packet revivals and fractional revivals are displayed by the time evolution of the expectation values of appropriate observables, enabling selective identification of different fractional revivals

    2007-01-01

    Quaternionic quantum mechanics has been revealed to be a very useful framework to describe quantum phenomena. In the case of two qubit compound systems we show that the complex projection of quaternionic pure states and quaternionic unitary maps permits the description of interesting phenomena such as decoherence and optimal entanglement generation. The approach, however, presents severe limitations for the case of multipartite or higher dimensional bipartite quantum systems as we point out

  13. Information mining in weighted complex networks with nonlinear rating projection

    Liao, Hao; Zeng, An; Zhou, Mingyang; Mao, Rui; Wang, Bing-Hong

    2017-10-01

    Weighted rating networks are commonly used by e-commerce providers nowadays. In order to generate an objective ranking of online items' quality according to users' ratings, many sophisticated algorithms have been proposed in the complex networks domain. In this paper, instead of proposing new algorithms we focus on a more fundamental problem: the nonlinear rating projection. The basic idea is that even though the rating values given by users are linearly separated, the real preference of users to items between the different given values is nonlinear. We thus design an approach to project the original ratings of users to more representative values. This approach can be regarded as a data pretreatment method. Simulation in both artificial and real networks shows that the performance of the ranking algorithms can be improved when the projected ratings are used.

    2014-08-01

    The project management of complex instruments for ground-based large telescopes is a challenge itself. A good management is a clue for project success in terms of performance, schedule and budget. Being on time has become a strict requirement for two reasons: to assure the arrival at the telescope due to the pressure on demanding new instrumentation for this first world-class telescopes and to not fall in over-costs. The budget and cash-flow is not always the expected one and has to be properly handled from different administrative departments at the funding centers worldwide distributed. The complexity of the organizations, the technological and scientific return to the Consortium partners and the participation in the project of all kind of professional centers working in astronomical instrumentation: universities, research centers, small and large private companies, workshops and providers, etc. make the project management strategy, and the tools and procedures tuned to the project needs, crucial for success. MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) is a facility instrument of the 10.4m GTC (La Palma, Spain) working at optical wavelengths that provides both Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) capabilities at resolutions in the range R=6,000-20,000. The project is an initiative led by Universidad Complutense de Madrid (Spain) in collaboration with INAOE (Mexico), IAA-CSIC (Spain) and Universidad Politécnica de Madrid (Spain). MEGARA is being developed under contract with GRANTECAN.

  18. Tailoring Enterprise Systems Engineering Policy for Project Scale and Complexity

    Science.gov (United States)

    Cox, Renee I.; Thomas, L. Dale

    2014-01-01

    Space systems are characterized by varying degrees of scale and complexity. Accordingly, cost-effective implementation of systems engineering also varies depending on scale and complexity. Recognizing that systems engineering and integration happen everywhere and at all levels of a given system and that the life cycle is an integrated process necessary to mature a design, the National Aeronautic and Space Administration's (NASA's) Marshall Space Flight Center (MSFC) has developed a suite of customized implementation approaches based on project scale and complexity. While it may be argued that a top-level system engineering process is common to and indeed desirable across an enterprise for all space systems, implementation of that top-level process and the associated products developed as a result differ from system to system. The implementation approaches used for developing a scientific instrument necessarily differ from those used for a space station. .

    Full Text Available Managing large capital construction projects requires the coordination of a multitude of human, organizational, technical, and natural resources. Quite often, the engineering and construction complexities of such projects are overshadowed by economic, societal, and political challenges. The ramifications and effects, which result from differences between early project cost estimates and the bid price or the final project cost, are significant. Over the time span between the initiation of a project and the completion of construction many factors influence a project's final costs. This time span is normally several years in duration but for highly complex and technologically challenging projects, project duration can easily exceed a decade. Over that period, changes to the project scope often occur. The subject here is a presentation of strategies that support realistic cost estimating. Through literature review and interviews with transportation agencies in the U.S. and internationally the authors developed a database of the factors that are the root causes of cost estimation problemsGestionar proyectos de construcción de grandes capitales requiere de la coordinación de una multitud de recursos humanos, organizacionales, técnicos y naturales.

  1. Knowledge Sharing Strategies for Large Complex Building Projects.

    Directory of Open Access Journals (Sweden)

    Esra Bektas

    2013-06-01

    Full Text Available The construction industry is a project-based sector with a myriad of actors such as architects, construction companies, consultants, producers of building materials (Anumba et al., 2005. The interaction between the project partners is often quite limited, which leads to insufficient knowledge sharing during the project and knowledge being unavailable for reuse (Fruchter et al. 2002. The result can be a considerable amount of extra work, delays and cost overruns. Design outcomes that are supposed to function as boundary objects across different disciplines can lead to misinterpretation of requirements, project content and objectives. In this research, knowledge is seen as resulting from social interactions; knowledge resides in communities and it is generated through social relationships (Wenger 1998, Olsson et al. 2008. Knowledge is often tacit, intangible and context-dependent and it is articulated in the changing responsibilities, roles, attitudes and values that are present in the work environment (Bresnen et al., 2003. In a project environment, knowledge enables individuals to solve problems, take decisions, and apply these decisions to actions. In order to achieve a shared understanding and minimize the misunderstanding and misinterpretations among project actors, it is necessary to share knowledge (Fong 2003. Sharing knowledge is particularly crucial in large complex building projects (LCBPs in order to accelerate the building process, improve architectural quality and prevent mistakes or undesirable results. However, knowledge sharing is often hampered through professional or organizational boundaries or contractual concerns. When knowledge is seen as an organizational asset, there is little willingness among project organizations to share their knowledge. Individual people may recognize the need to promote knowledge sharing throughout the project, but typically there is no deliberate strategy agreed by all project partners to address

  2. WAYS TO IMPROVE RISK MANAGEMENT IN COMPLEX PROJECTS

    Directory of Open Access Journals (Sweden)

    Emilia IORDACHE

    2012-01-01

    Full Text Available Risk is present in all human activities; it can be associated with health, security, economy or environment. The goal of risk management is to control, prevent or decrease potential damages. Technically speaking, risk management means all the activities coordinated so as to orient and monitor an organization from the risk perspective. Risk management helps formulate the most adequate decisions by taking account of uncertainties and their effects upon the accomplishment of proposed goals, and argues the need to lay down and implement coercive, preventive actions typical of the management of a company. The benefits of good risk management and also the consequences of bad management shall undoubtedly be felt by an organization’s board, employees, shareholders, customers as well as by all other entities concerned with organizational performance. Projects generally include a number of risks in common with those in business as well as certain typical ones. In complex projects, it is this very feature – complexity – which generates the need to implement risk management for the purpose to diminish, remove, and monitor the risks which can influence the development of a project.

    2016-09-01

    Full Text Available Construction projects have always been complex. By growing trend of this complexity, implementations of large-scale constructions become harder. Hence, evaluating and understanding these complexities are critical. Correct evaluation of a project complication can provide executives and managers with good source to use. Fuzzy analytic network process (ANP is a logical and systematic approach toward defining, evaluation, and grading. This method allows for analyzing complex systems, and determining complexity of them. In this study, by taking advantage of fuzzy ANP, effective indexes for development of complications in large-scale construction projects in Iran have been determined and prioritized. The results show socio-political, project system interdependencies, and technological complexity indexes ranked top to three. Furthermore, in comparison of three main huge projects: commercial-administrative, hospital, and skyscrapers, the hospital project had been evaluated as the most complicated. This model is beneficial for professionals in managing large-scale projects.

    Full Text Available Croatia has one of its weakest economies in European Union. The most powerful engine driving a nation’s economy is its businesses. But Croatian business is not faring well. The Croatian government is hoping tourism will help revive the economy. This is a realistic hope but one that will be realized only through concerted action by business, government, and the education sector.

  8. The ethics of reviving long extinct species.

    Sandler, Ronald

    2014-04-01

    There now appears to be a plausible pathway for reviving species that have been extinct for several decades, centuries, or even millennia. I conducted an ethical analysis of de-extinction of long extinct species. I assessed several possible ethical considerations in favor of pursuing de-extinction: that it is a matter of justice; that it would reestablish lost value; that it would create new value; and that society needs it as a conservation last resort. I also assessed several possible ethical arguments against pursuing de-extinction: that it is unnatural; that it could cause animal suffering; that it could be ecologically problematic or detrimental to human health; and that it is hubristic. There are reasons in favor of reviving long extinct species, and it can be ethically acceptable to do so. However, the reasons in favor of pursuing de-extinction do not have to do with its usefulness in species conservation; rather, they concern the status of revived species as scientific and technological achievements, and it would be ethically problematic to promote de-extinction as a significant conservation strategy, because it does not prevent species extinctions, does not address the causes of extinction, and could be detrimental to some species conservation efforts. Moreover, humanity does not have a responsibility or obligation to pursue de-extinction of long extinct species, and reviving them does not address any urgent problem. Therefore, legitimate ecological, political, animal welfare, legal, or human health concerns associated with a de-extinction (and reintroduction) must be thoroughly addressed for it to be ethically acceptable. © 2013 Society for Conservation Biology.

  9. The Revival of Confucianism in Modern Chinese Politics

    DEFF Research Database (Denmark)

    Overgaard, Signe

    of the phenomenon, this researcher will show that while the domestic legitimization crisis may have been the starting point for utilizing ideas from Confucianism, the purposes have broadened to also include strengthening Chinas soft power image and reinforcing the Chinese Model of Development as well.......In recent years the Chinese government has increasingly employed ideas from Confucian thought in political campaigns and projects. This revival of Confucianism by the Chinese government is a paradox because Confucianism and the social values and structures it stood for has been under heavy attack...... to fill an ideological gap after Communism has lost its appeal as a result of three decades of capitalist driven economic development and political reforms (Chen Ming 2009; Cho and Jeung 2008). Filling an ideological gap however does not seem to be the only purpose. By giving a comprehensive account...

  11. Soil Investigation Aspects of a Complex Metro Project in Amsterdam

    Science.gov (United States)

    Herbschleb, Jurgen

    The municipality of Amsterdam wishes to reduce the level of car traffic within the City Centre. As a consequence the public transport is to be extended by a new (bored) North/South Metro line. The excavation depths for the stations will exceed 30 m and will be constructed in difficult soft soil conditions. A further significant aspect is that the building pits are very near (3 to 5 m) to buildings of historical importance. The design philosophy of the station boxes was to determine an acceptable balance between the safety requirements and construction costs. The guidelines for the design, both for the building pits and the bored tunnel, are the predicted deformations of the adjacent building foundations. One of the more important geotechnical risks for this project is incorrect determination of the deformations arising from the building processes alongside the route of the metro. As such it should be realised that advanced finite element programs with second order material models require different geotechnical parameters than analytical models. The careful selection of calculation (soil) models, the level of safety (risk analysis), and site investigation is the start of the determination of the geotechnical parameters. This paper will focus on the interpretation of the site investigation for this complex project and will concentrate on the process followed, the problems encountered with the interpretation, the obtained results, and the used tools for geotechnical risk management.

  12. A time-frequency analysis of wave packet fractional revivals

    International Nuclear Information System (INIS)

    Ghosh, Suranjana; Banerji, J

    2007-01-01

    We show that the time-frequency analysis of the autocorrelation function is, in many ways, a more appropriate tool to resolve fractional revivals of a wave packet than the usual time-domain analysis. This advantage is crucial in reconstructing the initial state of the wave packet when its coherent structure is short-lived and decays before it is fully revived. Our calculations are based on the model example of fractional revivals in a Rydberg wave packet of circular states. We end by providing an analytical investigation which fully agrees with our numerical observations on the utility of time-frequency analysis in the study of wave packet fractional revivals

    2011-01-01

    The Turkic Accelerator Complex (TAC) project has been developed with the support of the Turkish State Planning Organization by the collaboration of 10 Turkish universities. The complex is planned to have four main facilities, namely: SASE FEL Facility based on 1 GeV Electron Linac, Third Generation Synchrotron Radiation Facility (SR) based on 3.56 GeV Positron Synchrotron, Super-Charm factory (√s = 3.77 GeV) by colliding the electron beam coming from the linac with an energy of 1 GeV and positron beam coming through the positron ring with an energy of 3.56 GeV, GeV scale proton accelerator. Later has two-fold goal: Neutron Spallation Source (NSS) and ADS. The proton accelerator construction will have 3 MeV, 100 MeV, and 1 GeV phases. The technical design report is planned to be finished in 2013. Since Turkey has essential Thorium reserves the ADS becomes very attractive for our country as emerging energy technology. (author)

  15. Relansarea proiectului de integrare europeană presupune o luptă politico-culturală cu ideologia neoliberală. Interviu cu Profesorul Angelo Chielli (The revival of the European integration project requires a political and cultural struggle with the neoliberal ideology

    Directory of Open Access Journals (Sweden)

    Sorin BOCANCEA

    2015-06-01

    Full Text Available The conflicts within the European Union have always been and will always be purely political. The concentration of power in the hands of independent and supranational authorities leads to their removal from the control of the political institutions and democratic procedures. A revival of the European integration project could be based on a tough politico-cultural fight in a position to undermine the neoliberal ideology. Restarting the process of European integration cannot be the fruit of a ghostly economic recovery or stabilization of the balance states, but only as a result of a change in perspectives and objectives. To further be a viable project, the European Union needs some changes. Politically, it must be a question of political conflict recovery, reunification of alternative forces and proposing a different idea of Europe compared with that of the markets, specific to the neoliberalism. In the ideal contents plan, the concept of solidarity needs to be re-proposed, as a legal principle that allows the establishment of links outside those of family or community type. In this respect, solidarity is not only a guardianship, but even a direct exercise of freedoms.

    2004-01-01

    In this paper I review the causes for the renewed interest in the near-term revival of nuclear power in the U.S. and internationally. I comment on the progress already made in the U.S. in restarting a second era of commercial nuclear power plant construction, and on what is required going forwards, from a utilities perspective, to commit to and implement new plant orders. I review the specific nuclear projects discussed and committed to in the U.S. and abroad in terms of utilities, sites, vendor and suppliers teams, and project arrangements. I will then offer some tentative conclusions regarding the prospects for a near-term U.S. and global nuclear power revival

  18. Reviving nuclear requires broad technology fix

    International Nuclear Information System (INIS)

    Hyman, L.S.

    1991-01-01

    What will it take to revive nuclear power in this country? For a beginning, nuclear plants must be the lowest-cost alternative to providing additional energy supplies; they must be smaller in size and easier to build and license than in the past, and public confidence in nuclear power must be restored. But even this is not enough to attract investors, he says. Regulatory policies, corporate structures, and financial arrangements must change as well. Hyman offers some ideas for changes that would be attractive to investors: place construction work in progress in the rate base, create a pay-as-you-go approach to construction; federal rather than state regulation of power rates; and ownership and construction by a consortium of electrical equipment manufacturers, engineering and construction firms, utilities, and fuel supplies. But even then, Hyman is not optimistic. Fixing nuclear power is possible only if there is a need for the product, the price is right, the profit is adequate, the people want it, the waste is disposed of, and somebody will take the risk of financing its revival

    2018-01-01

    Full Text Available Abstract. Aim. The aim of the research is to analyze the reasons for the migration of mountain people to the plain, the identification of the most significant stages of the resettlement movement in the Republic of Dagestan, the identification of ways to preserve and revive the mountain villages of Dagestan. Discussion. At present, the outflow of population from mountainous areas to flat land is actively continuing which leads to the abandonment of dozens of mountain villages. Therefore, in modern conditions, the urgent task is to preserve and revive the mountain villages of Dagestan. For this, first of all, the creation of a developed infrastructure, high-quality medical care and education, as well as the revival of traditional forms of land use, horticulture and cattle breeding, creation of new jobs are necessary in mountainous areas. The traditional habitat should be attractive for young people. The understanding of the problem of preservation and revival of the mountainous regions of Dagestan exists not only at the governmental level but also in Dagestan society as a whole. It is shown that the natural-historical and cultural complexes of Dagestan should be used for the development of various types of tourism, especially cultural-cognitive and ethno-tourism, ecological and religious tourism. Conclusion. Almost every ancient mountain village of Dagestan is actually an ethnographic museum in the open air, therefore the development of the tourism industry, in particular cultural-cognitive and ethno-tourism, will contribute to the preservation and revival of ancient auls in the republic.

  4. Scholarship and Language Revival: Language Ideologies in Corpus Development for Revived Manx

    Directory of Open Access Journals (Sweden)

    Lewin Christopher

    2017-08-01

    Full Text Available In this article the role of different ideological viewpoints concerning corpus development within the Manx revival movement in the second half of the twentieth century is explored. In particular, the work of two prominent figures is examined: the Celtic scholar Robert L. Thomson, who published extensively especially on Manx language and literature, and also contributed to the revival, particularly as editor of several pedagogical resources and as a member of the translation committee Coonceil ny Gaelgey, and Douglas Fargher, a tireless activist and compiler of an English-Manx Dictionary (1979. Broadly speaking, Thomson was of a more preservationist bent, cautious in adapting the native resources of the language and wary of straying too far from attested usage of the traditional language, while Fargher was more radical and open especially to borrowing from Irish and Scottish sources. Both were concerned, in somewhat different ways, to remove perceived impurities or corruptions from the language, and were influenced by the assumptions of existing scholarship. A close reading of the work of these scholar-activists sheds light on the tensions within the revival movement regarding its response to the trauma of language death and the questions of legitimacy and authenticity in the revived variety. Particular space is devoted to an analysis of the preface of Fargher’s dictionary, as well as certain features of the body of the work itself, since this volume is probably the most widely consulted guide to the use of the language today. Finally, it is argued that the Manx language movement today would benefit from a reassessment and discussion of the ideological currents of the past and present, and a judicious evaluation of both the strengths and weaknesses of existing reference works.

  5. REVIVING SOME BASIC CONCEPTS IN ETHICAL REGISTER

    Directory of Open Access Journals (Sweden)

    CARMEN COZMA

    2015-11-01

    Full Text Available Being sensitive to the challenges placed before us in a globalizing world, it is obviously that the ethical benchmark became one of the priorities in our individual and communitarian life. An in-depth knowledge of both the axiological and normative dimensions of ethics can open an important way for an adequate approach of today’s problems. By rethinking the foundations, we may reach accuracy as regards what does really matter in life. So, a call to revive some value-laden concepts coming from the ancient Greek moral philosophy represents the aim of this paper, to emphasize the support given us by healthy roots for reflection and understanding, in part at least, our present problematic situation in the world.

  6. Nuclear energy: exit or revival? International aspects

    International Nuclear Information System (INIS)

    2001-11-01

    This colloquium took place less than 1 year after the decision of the US of revival of their nuclear program. Thus the international context has changed, even if nuclear contestation remains as strong as in the past. Among governments, some positions preach the banishment of nuclear energy while others consider the nuclear option as the only solution to meet the growing up energy demand and the future environmental and economical stakes. This report makes a synthesis of the different talks given by the participants during the 3 round tables of the colloquium on the future of nuclear energy: the ecological stake, the democratic stake, and the energy policy stake. Four talks of French government representatives open and conclude the debates of the different round tables. (J.S.)

  7. Quantum revivals and magnetization tunneling in effective spin systems

    International Nuclear Information System (INIS)

    Krizanac, M; Altwein, D; Vedmedenko, E Y; Wiesendanger, R

    2016-01-01

    Quantum mechanical objects or nano-objects have been proposed as bits for information storage. While time-averaged properties of magnetic, quantum-mechanical particles have been extensively studied experimentally and theoretically, experimental investigations of the real time evolution of magnetization in the quantum regime were not possible until recent developments in pump–probe techniques. Here we investigate the quantum dynamics of effective spin systems by means of analytical and numerical treatments. Particular attention is paid to the quantum revival time and its relation to the magnetization tunneling. The quantum revival time has been initially defined as the recurrence time of a total wave-function. Here we show that the quantum revivals of wave-functions and expectation values in spin systems may be quite different which gives rise to a more sophisticated definition of the quantum revival within the realm of experimental research. Particularly, the revival times for integer spins coincide which is not the case for half-integer spins. Furthermore, the quantum revival is found to be shortest for integer ratios between the on-site anisotropy and an external magnetic field paving the way to novel methods of anisotropy measurements. We show that the quantum tunneling of magnetization at avoided level crossing is coherent to the quantum revival time of expectation values, leading to a connection between these two fundamental properties of quantum mechanical spins.

    We calculate the quantum revival time for a wave packet initially well localized in a one-dimensional potential in the presence of an external periodic modulating field. The dependence of the revival time on various parameters of the driven system is shown analytically. As an example of an application of our approach, we compare the analytically obtained values of the revival time for various modulation strengths with the numerically computed ones in the case of a driven gravitational cavity. We show that they are in very good agreement

  11. Computational Experiment Study on Selection Mechanism of Project Delivery Method Based on Complex Factors

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Project delivery planning is a key stage used by the project owner (or project investor for organizing design, construction, and other operations in a construction project. The main task in this stage is to select an appropriate project delivery method. In order to analyze different factors affecting the PDM selection, this paper establishes a multiagent model mainly to show how project complexity, governance strength, and market environment affect the project owner’s decision on PDM. Experiment results show that project owner usually choose Design-Build method when the project is very complex within a certain range. Besides, this paper points out that Design-Build method will be the prior choice when the potential contractors develop quickly. This paper provides the owners with methods and suggestions in terms of showing how the factors affect PDM selection, and it may improve the project performance.

    Energy Technology Data Exchange (ETDEWEB)

    GRAY BJ

    2007-11-26

    This paper describes the results of a year-long project, sponsored by the Energy Facility Contractors Group (EFCOG) and designed to improve overall electrical safety performance throughout Department of Energy (DOE)-owned sites and laboratories. As evidenced by focused metrics, the Project was successful primarily due to the joint commitment of contractor and DOE electrical safety experts, as well as significant support from DOE and contractor senior management. The effort was managed by an assigned project manager, using classical project-management principles that included execution of key deliverables and regular status reports to the Project sponsor. At the conclusion of the Project, the DOE not only realized measurable improvement in the safety of their workers, but also had access to valuable resources that will enable them to do the following: evaluate and improve electrical safety programs; analyze and trend electrical safety events; increase electrical safety awareness for both electrical and non-electrical workers; and participate in ongoing processes dedicated to continued improvement.

  15. 340 waste handling complex: Deactivation project management plan

    Stordeur, R.T.

    1998-01-01

    This document provides an overview of the strategy for deactivating the 340 Waste Handling Complex within Hanford's 300 Area. The plan covers the period from the pending September 30, 1998 cessation of voluntary radioactive liquid waste (RLW) transfers to the 340 Complex, until such time that those portions of the 340 Complex that remain active beyond September 30, 1998, specifically, the Retention Process Sewer (RPS), can also be shut down and deactivated. Specific activities are detailed and divided into two phases. Phase 1 ends in 2001 after the core RLW systems have been deactivated. Phase 2 covers the subsequent interim surveillance of deactivated and stand-by components during the period of continued RPS operation, through the final transfer of the entire 340 Complex to the Environmental Restoration Contractor. One of several possible scenarios was postulated and developed as a budget and schedule planning case

    The ability of quantum systems to host exponentially complex dynamics has the potential to revolutionize science and technology. Therefore, much effort has been devoted to developing of protocols for computation, communication and metrology, which exploit this scaling, despite formidable technical difficulties. Here we show that the mere frequent observation of a small part of a quantum system can turn its dynamics from a very simple one into an exponentially complex one, capable of universal quantum computation. After discussing examples, we go on to show that this effect is generally to be expected: almost any quantum dynamics becomes universal once 'observed' as outlined above. Conversely, we show that any complex quantum dynamics can be 'purified' into a simpler one in larger dimensions. We conclude by demonstrating that even local noise can lead to an exponentially complex dynamics.

    2016-01-01

    In this paper, we demonstrate the revival and robustness of Bures distance discord in comparison with entanglement under local decoherent evolutions. The results show that in depolarizing channel Bures distance discord revives after a dark point of time, while entanglement will damp into death without revival. In addition, in hybrid channel the declining initial condition can enable Bures distance discord to decay more smoothly within a limited time, but speed up the death of entanglement. In this sense, Bures distance discord is typically more robust against decoherence than entanglement. Furthermore, we also provide a geometric interpretation concerning these phenomena. - Highlights: • Bures distance discord is more robust against decoherence than entanglement. • Bures distance discord revives after a dark point of time, while entanglement damps to death. • The initial condition enables Bures distance discord to damp smoothly, but it speeds up the death of entanglement. • A geometric interpretation concerning these phenomena has been provided.

    2012-09-01

    Full Text Available Complexity is one of the most important issues influencing success of any construction project and there are literally different studies devoted to detect important factors increasing complexity of projects. During the past few years, there have been growing interests in developing mass construction projects in Iran. The proposed study of this paper uses Delphi technique to find out about important factors as barriers of construction projects in Iran. The results show that among 47 project complexity factors, 19 factors are more important than others are. The study groups different factors into seven categories including environmental, organizational, objectives, tasks, stakeholders, technological, information systems and determines the relative importance of each. In each group, many other sub group activities are determined and they are carefully investigated. The study provides some detailed suggestions on each category to reduce the complexity of construction project.

    2011-01-01

    In this paper a bound localized Dirac particle is shown to exhibit a revival of the zitterbewegung (ZB) oscillation amplitude. These revivals go beyond the known quasiclassical regenerations in which the ZB oscillation amplitude is decreasing from period to period. This phenomenon is studied in a Dirac oscillator and it is shown that it is possible to set up wave packets in which there is a regeneration of the initial ZB amplitude.

  2. Quantum wave-packet revivals in circular billiards

    International Nuclear Information System (INIS)

    Robinett, R.W.; Heppelmann, S.

    2002-01-01

    We examine the long-term time dependence of Gaussian wave packets in a circular infinite well (billiard) system and find that there are approximate revivals. For the special case of purely m=0 states (central wave packets with no momentum) the revival time is T rev (m=0) =8μR 2 /(ℎ/2π)π, where μ is the mass of the particle, and the revivals are almost exact. For all other wave packets, we find that T rev (m≠0) =(π 2 /2)T rev (m=0) ≅5T rev (m=0) and the nature of the revivals becomes increasingly approximate as the average angular momentum or number of m≠0 states is increased. The dependence of the revival structure on the initial position, energy, and angular momentum of the wave packet and the connection to the energy spectrum is discussed in detail. The results are also compared to two other highly symmetrical two-dimensional infinite well geometries with exact revivals, namely, the square and equilateral triangle billiards. We also show explicitly how the classical periodicity for closed orbits in a circular billiard arises from the energy eigenvalue spectrum, using a WKB analysis

  8. MODELS AND METHODS OF SAFETY-ORIENTED PROJECT MANAGEMENT OF DEVELOPMENT OF COMPLEX SYSTEMS: METHODOLOGICAL APPROACH

    Directory of Open Access Journals (Sweden)

    Олег Богданович ЗАЧКО

    2016-03-01

    Full Text Available The methods and models of safety-oriented project management of the development of complex systems are proposed resulting from the convergence of existing approaches in project management in contrast to the mechanism of value-oriented management. A cognitive model of safety oriented project management of the development of complex systems is developed, which provides a synergistic effect that is to move the system from the original (pre condition in an optimal one from the viewpoint of life safety - post-project state. The approach of assessment the project complexity is proposed, which consists in taking into account the seasonal component of a time characteristic of life cycles of complex organizational and technical systems with occupancy. This enabled to take into account the seasonal component in simulation models of life cycle of the product operation in complex organizational and technical system, modeling the critical points of operation of systems with occupancy, which forms a new methodology for safety-oriented management of projects, programs and portfolios of projects with the formalization of the elements of complexity.

  9. Complex governance system issues for transportation renewal projects

    2014-01-01

    Full Text Available The use of public–private partnerships (PPPs is growing in the United States in response to reductions in funding combined with an aging highway transportation infrastructure. Many other countries have longer experience with PPP and a greater understanding of the issues surrounding their use. The main governance issues to be addressed in PPPs deal with risk-sharing, relationships, contracts, and legal framework, and standard processes within dedicated organizational units. These governance issues are examined in the context of a case study for the US 36 Phase II PPP in Colorado. Findings suggest that for the US Phase II project, governance issues are resolved through more relational forms than prescriptive contractual language. Colorado has established a dedicated organizational unit to facilitate the use of PPPs, but there exist no standards or best practices in the United States for procurement, concession terms, or risk-sharing.

    2014-06-01

    Full Text Available The development and advancement of zakat institution in Malaysia has been through time influenced by the changing social, political and economic situation of the country. An important phenomenon which shaped the institution is Islamic revivalism. Consequently, zakat has been one of the institutions which government keened to enhance. Another factor merits to be considered is the introduction of economic policies in which the government affirmatively inclined towards Malay Muslims enabling them to compete economically with other wealthier races. Within the spirit of the policies together with the direct influence by the emerging factors resulted from the revivalism phenomenon, the government has introduced corporatization of zakat institution, a modern way of zakat management. This article aims to survey the development of zakat in Malaysia which reflects the continuous process of Islamic revivalism in the nation. As we shall see throughout the discussion, the role of zakat institution has been through time expanded to be one of the national economic tools.

  15. Complex Modified Hybrid Projective Synchronization of Different Dimensional Fractional-Order Complex Chaos and Real Hyper-Chaos

    Directory of Open Access Journals (Sweden)

    Jian Liu

    2014-11-01

    Full Text Available This paper introduces a type of modified hybrid projective synchronization with complex transformationmatrix (CMHPS for different dimensional fractional-order complex chaos and fractional-order real hyper-chaos. The transformationmatrix in this type of chaotic synchronization is a non-square matrix, and its elements are complex numbers. Based on the stability theory of fractional-order systems, by employing the feedback control technique, necessary and sufficient criteria on CMHPS are derived. Furthermore, CMHPS between fractional-order real hyper-chaotic Rössler system and other two different dimensional fractional-order complex Lorenz-like chaotic systems is provided as two examples to discuss reduced order and increased order synchronization, respectively.

    2016-08-10

    In this paper, the dynamics of entanglement is investigated in the presence of a noisy environment. We reveal its revival behavior and probe the mechanisms of this behavior via an information-theoretic approach. By analyzing the correlation distribution and the information flow within the composite system including the qubit subsystem and a noisy environment, it has been found that the subsystem-environment coupling can induce the quasi-periodic entanglement revival. Furthermore, the dynamical relationship among tripartite correlations, bipartite entanglement and local state information is explored, which provides a new insight into the non-Markovian mechanisms during the evolution.

  18. Modeling and Simulation of Project Management through the PMBOK® Standard Using Complex Networks

    Directory of Open Access Journals (Sweden)

    Luz Stella Cardona-Meza

    2017-01-01

    Full Text Available Discussion about project management, in both the academic literature and industry, is predominantly based on theories of control, many of which have been developed since the 1950s. However, issues arise when these ideas are applied unilaterally to all types of projects and in all contexts. In complex environments, management problems arise from assuming that results, predicted at the start of a project, can be sufficiently described and delivered as planned. Thus, once a project reaches a critical size, a calendar, and a certain level of ambiguity and interconnection, the analysis centered on control does not function adequately. Projects that involve complex situations can be described as adaptive complex systems, consistent in multiple interdependent dynamic components, multiple feedback processes, nonlinear relations, and management of hard data (process dynamics and soft data (executive team dynamics. In this study, through a complex network, the dynamic structure of a project and its trajectories are simulated using inference processes. Finally, some numerical simulations are described, leading to a decision making tool that identifies critical processes, thereby obtaining better performance outcomes of projects.

    Full Text Available This paper is derived from a dissertation and the main goal is to argue how the project-based curriculum, in a perspective of complexity, can offers some possibilities for an education on values introducing studies of nowadays social problems into the school. To achieve the objectives was considered a project developed with a ten years old students. The investigation was based on project activities and daily field. As a result we have demonstrated the project-based curriculum – using the complexity, interdisciplinary and transversality as references – can help school to combine the disciplinary knowledge to the ethical formation. The investigation has show that the project-based curriculum may lead schools to succeed in implementing an education in values, pointing out some directions to develop citizens who can deal with diversity and conflicts as well as capable of get indignant with the injustices and have disposal to individual and collective welfare.

    Segmentation algorithm is an important part of layout analysis, considering the efficiency advantage of the top-down approach and the particularity of the object, a breakdown of projection layout segmentation algorithm. Firstly, the algorithm will algorithm first partitions the text image, and divided into several columns, then for each column scanning projection, the text image is divided into several sub regions through multiple projection. The experimental results show that, this method inherits the projection itself and rapid calculation speed, but also can avoid the effect of arc image information page segmentation, and also can accurate segmentation of the text image layout is complex.

Huntington and F. Fukuyama are clear examples.  They are actively gearing the international institutions so cleverly that Muslim Ummah does not even realize their ill motives and objectives.  They brought their leadership in a confronting position with Muslim Ummah and hence threatening the world peace.  This situation prompted us to look at our principal sources of inspiration, which are, the Qur’an, Sunnah of the Prophet (SAW, and examples of the “enlightened Caliphs” and see if we could work out a seminal guidelines for our rectification  and revival.  We have gathered together some of these impressions; these are all tentative, nothing final about them, but these are here nonetheless.

  4. EpiCollect+: linking smartphones to web applications for complex data collection projects.

    Science.gov (United States)

    Aanensen, David M; Huntley, Derek M; Menegazzo, Mirko; Powell, Chris I; Spratt, Brian G

    2014-01-01

    Previously, we have described the development of the generic mobile phone data gathering tool, EpiCollect, and an associated web application, providing two-way communication between multiple data gatherers and a project database. This software only allows data collection on the phone using a single questionnaire form that is tailored to the needs of the user (including a single GPS point and photo per entry), whereas many applications require a more complex structure, allowing users to link a series of forms in a linear or branching hierarchy, along with the addition of any number of media types accessible from smartphones and/or tablet devices (e.g., GPS, photos, videos, sound clips and barcode scanning). A much enhanced version of EpiCollect has been developed (EpiCollect+). The individual data collection forms in EpiCollect+ provide more design complexity than the single form used in EpiCollect, and the software allows the generation of complex data collection projects through the ability to link many forms together in a linear (or branching) hierarchy. Furthermore, EpiCollect+ allows the collection of multiple media types as well as standard text fields, increased data validation and form logic. The entire process of setting up a complex mobile phone data collection project to the specification of a user (project and form definitions) can be undertaken at the EpiCollect+ website using a simple 'drag and drop' procedure, with visualisation of the data gathered using Google Maps and charts at the project website. EpiCollect+ is suitable for situations where multiple users transmit complex data by mobile phone (or other Android devices) to a single project web database and is already being used for a range of field projects, particularly public health projects in sub-Saharan Africa. However, many uses can be envisaged from education, ecology and epidemiology to citizen science.

    -free lanes west of the plumes were the first to show the colour change, and elongated due to the zonal windshear to form the characteristic 'S-shape' of the revival complex. The aerosol-free air was redistributed and mixed throughout the SEB by the zonal flow, following a westward-moving southern branch and an eastward-moving northern branch that revived the brown colouration over ∼200 days. The transition from the cool conditions of the SEBZ during the fade to the revived SEB caused a 2-4 K rise in 500-mbar temperatures (leaving a particularly warm southern SEB) and a reduction of aerosol opacity by factors of 2-3. Newly-cleared gaps in the upper tropospheric aerosol layer appeared different in filters sensing the ∼700-mbar cloud deck and the 2-3 bar cloud deck, suggesting complex vertical structure in the downdrafts. The last stage of the revival was the re-establishment of normal convective activity northwest of the GRS in September 2011, ∼840 days after the last occurrence in June 2009. Moist convection may therefore play an important role in controlling the timescale and atmospheric variability during the SEB life cycle.

  9. Revivals and entanglement from initially entangled mixed states of a damped Jaynes-Cummings model

    International Nuclear Information System (INIS)

    Rendell, R.W.; Rajagopal, A.K.

    2003-01-01

    An exact density matrix of a phase-damped Jaynes-Cummings model (JCM) with entangled Bell-like initial states formed from a model two-state atom and sets of adjacent photon number states of a single-mode radiation field is presented. The entanglement of the initial states and the subsequent time evolution is assured by finding a positive lower bound on the concurrence of local 2x2 projections of the full 2x∞ JCM density matrix. It is found that the time evolution of the lower bound of the concurrence systematically captures the corresponding collapse and revival features in atomic inversion, relative entropies of atomic and radiation, mutual entropy, and quantum deficit. The atom and radiation subsystems exhibit alternating sets of collapses and revivals in a complementary fashion due to the initially mixed states of the atom and radiation employed here. This is in contrast with the result obtained when the initial state of the dissipationless system is a factored pure state of the atom and radiation, where the atomic and radiation entropies are necessarily the same. The magnitudes of the entanglement lower bound and the atomic and radiation revivals become larger as both the magnitude and phase of the Bell-like initial state contribution increase. The time evolution of the entropy difference of the total system and that of the radiation subsystem exhibit negative regions called 'supercorrelated' states which do not appear in the atomic subsystem. Entangled initial states are found to enhance this supercorrelated feature. Finally, the effect of phase damping is to randomize both the subsystems for asymptotically long times. It may be feasible to experimentally investigate the results presented here using the Rabi oscillation methods of microwave and optical cavity quantum electrodynamics since pure photon number states have recently been produced and observed

    2016-09-01

    Full Text Available Non functional requirements must be selected for implementation together with functional requirements to enhance the success of software projects. Three approaches exist for performing the prioritization of non functional requirements using the suitable prioritization technique. This paper performs experimentation on three different complexity versions of the industrial software project using cost-value prioritization technique employing three approaches. Experimentation is conducted to analyze the accuracy of individual approaches and the variation of accuracy with the complexity of the software project. The results indicate that selecting non functional requirements separately, but in accordance with functionality has higher accuracy amongst the other two approaches. Further, likewise other approaches, it witnesses the decrease in accuracy with increase in software complexity but the decrease is minimal.

  11. Methods Dealing with Complexity in Selecting Joint Venture Contractors for Large-Scale Infrastructure Projects

    Directory of Open Access Journals (Sweden)

    Ru Liang

    2018-01-01

    Full Text Available The magnitude of business dynamics has increased rapidly due to increased complexity, uncertainty, and risk of large-scale infrastructure projects. This fact made it increasingly tough to “go alone” into a contractor. As a consequence, joint venture contractors with diverse strengths and weaknesses cooperatively bid for bidding. Understanding project complexity and making decision on the optimal joint venture contractor is challenging. This paper is to study how to select joint venture contractors for undertaking large-scale infrastructure projects based on a multiattribute mathematical model. Two different methods are developed to solve the problem. One is based on ideal points and the other one is based on balanced ideal advantages. Both of the two methods consider individual difference in expert judgment and contractor attributes. A case study of Hong Kong-Zhuhai-Macao-Bridge (HZMB project in China is used to demonstrate how to apply these two methods and their advantages.

  12. Analyzing Integrated Cost-Schedule Risk for Complex Product Systems R&D Projects

    Directory of Open Access Journals (Sweden)

    Zhe Xu

    2014-01-01

    Full Text Available The vast majority of the research efforts in project risk management tend to assess cost risk and schedule risk independently. However, project cost and time are related in reality and the relationship between them should be analyzed directly. We propose an integrated cost and schedule risk assessment model for complex product systems R&D projects. Graphical evaluation review technique (GERT, Monte Carlo simulation, and probability distribution theory are utilized to establish the model. In addition, statistical analysis and regression analysis techniques are employed to analyze simulation outputs. Finally, a complex product systems R&D project as an example is modeled by the proposed approach and the simulation outputs are analyzed to illustrate the effectiveness of the risk assessment model. It seems that integrating cost and schedule risk assessment can provide more reliable risk estimation results.

  14. Quasi-projective synchronization of fractional-order complex-valued recurrent neural networks.

    Science.gov (United States)

    Yang, Shuai; Yu, Juan; Hu, Cheng; Jiang, Haijun

    2018-08-01

    In this paper, without separating the complex-valued neural networks into two real-valued systems, the quasi-projective synchronization of fractional-order complex-valued neural networks is investigated. First, two new fractional-order inequalities are established by using the theory of complex functions, Laplace transform and Mittag-Leffler functions, which generalize traditional inequalities with the first-order derivative in the real domain. Additionally, different from hybrid control schemes given in the previous work concerning the projective synchronization, a simple and linear control strategy is designed in this paper and several criteria are derived to ensure quasi-projective synchronization of the complex-valued neural networks with fractional-order based on the established fractional-order inequalities and the theory of complex functions. Moreover, the error bounds of quasi-projective synchronization are estimated. Especially, some conditions are also presented for the Mittag-Leffler synchronization of the addressed neural networks. Finally, some numerical examples with simulations are provided to show the effectiveness of the derived theoretical results. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2007-01-01

    We investigate many characteristic features of revival and fractional revival phenomena via derived analytic expressions for an autocorrelation function of a one-dimensional Rydberg atom with weighting probabilities modelled by a Gaussian or a Lorentzian distribution. The fractional revival phenomenon in the ionization probabilities of a one-dimensional Rydberg atom irradiated by two short half-cycle pulses is also studied. When many states are involved in the formation of the wave packet, the revival is lower and broader than the initial wave packet and the fractional revivals overlap and disappear with time

    We report on the phenomena of the periodic spontaneous collapse and revival in the dynamics of an atomic beam interacting with a single-mode and coherent-state light field. Conventional collapse and revival by Eberly et al. [Phys. Rev. Lett. 44 (1980) 1323] are presented in the case of the evolution with time of the population inversion. Here, we study the evolution with coupling strength of population inversion. We define the collapse and revival coupling strengths as characteristic parameters to describe the above collapse and revival. Furthermore, we present the analytic formulas for the population inversion, the collapse and revival coupling strengths

    2017-06-01

    Full Text Available The growing global importance of large infrastructure projects has piqued the interest of many researchers in a variety of issues related to the management of large, multi-stakeholder projects, characterized by their high complexity and intense interaction among numerous stake-holders with distinct levels of responsibility. The objective of this study is to provide an overview of the academic literature focused on the management of these kinds of projects, describing the main themes considered, the lines of research identified and prominent trends. Bibliometric analysis techniques were used as well as network and content analysis. Research for information was performed in the scientific database, ISI Web of Knowledge and Scopus. The initial sample analysis consisted of 144 papers published between 1984 and 2014 and expanded to the references cited in these papers. The models identified in the literature converge with the following key-processes: project delivery systems; risk-management models; project cost management; public-private partnership.

    2013-01-01

    We investigate a new generalized projective synchronization between two complex dynamical networks of different sizes. To the best of our knowledge, most of the current studies on projective synchronization have dealt with coupled networks of the same size. By generalized projective synchronization, we mean that the states of the nodes in each network can realize complete synchronization, and the states of a pair of nodes from both networks can achieve projective synchronization. Using the stability theory of the dynamical system, several sufficient conditions for guaranteeing the existence of the generalized projective synchronization under feedback control and adaptive control are obtained. As an example, we use Chua's circuits to demonstrate the effectiveness of our proposed approach

    2018-03-01

    The asymptotic projection technique is used to investigate the polarization effect that arises from the interaction between the relaxed, and frozen monomeric charge densities of a set of neutral and charged hydrogen bonded complexes. The AP technique based on the resolution of the original Kohn-Sham equations can give an acceptable qualitative description of the polarization effect in neutral complexes. The significant overlap of the electron densities, in charged and π-conjugated complexes, impose further development of a new functional, describing the coupling between constrained and non-constrained electron densities within the AP technique to provide an accurate representation of the polarization effect.

    Let $V$ be a complex nonsingular projective 3-fold of general type with $\\chi(\\omega_V)\\geq 0$ (resp. $>0$). We prove that the m-canonical map $\\Phi_{|mK_V|}$ is birational onto its image for all $m\\ge 14$ (resp. $\\geq 8$). Known examples show that the lower bound $r_3=14$ (resp. $=8$) is optimal.

  7. A Dynamic Intelligent Decision Approach to Dependency Modeling of Project Tasks in Complex Engineering System Optimization

    2013-01-01

    Full Text Available Complex engineering system optimization usually involves multiple projects or tasks. On the one hand, dependency modeling among projects or tasks highlights structures in systems and their environments which can help to understand the implications of connectivity on different aspects of system performance and also assist in designing, optimizing, and maintaining complex systems. On the other hand, multiple projects or tasks are either happening at the same time or scheduled into a sequence in order to use common resources. In this paper, we propose a dynamic intelligent decision approach to dependency modeling of project tasks in complex engineering system optimization. The approach takes this decision process as a two-stage decision-making problem. In the first stage, a task clustering approach based on modularization is proposed so as to find out a suitable decomposition scheme for a large-scale project. In the second stage, according to the decomposition result, a discrete artificial bee colony (ABC algorithm inspired by the intelligent foraging behavior of honeybees is developed for the resource constrained multiproject scheduling problem. Finally, a certain case from an engineering design of a chemical processing system is utilized to help to understand the proposed approach.

  8. Indigenous food security revival strategies at the village level: The gender factor implications

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available This article is based on an evaluation concerning the practice of the Zunde raMambo concept (commonly referred to as Zunde in four of Zimbabwe’s 52 districts; (Mangwe, Lupane, Guruve and Hwedza. Zunde is a social security system providing protection against food shortages to vulnerable families and is coordinated by chiefs. The Zunde concept identifies with Ndebele and Shona rural communities in Zimbabwe. Thus, this evaluation sought to determine the relevance and fulfilment of the Zunde project objectives, namely: efficiency, effectiveness, impact and sustainability. The revived Zunde practice extends a long way in reducing food insecurity in vulnerable communities. Although the concept may be as old as the Zimbabwean culture, it had been abandoned as communities became urbanised. The Chief’s Council of Zimbabwe, in collaboration with the Nutrition Unit of the Ministry of Health and Child Welfare have rekindled it. However, to revive this indigenous knowledge practice, there is need to assess the nature of existing social and economic structures, leadership, gender roles and the availability of resources such as land, inputs and implements. This article, which is based on both qualitative and quantitative data, collected between September 2013 and March 2014, goes on to reflect on policy issues surrounding disaster risk reduction (DRR and survival strategies used by vulnerable communities in rural areas of Zimbabwe. It recommends that the gender factor approach offers the best means possible to understand peoples’ needs and challenges as well as how these can be satisfied and resolved respectively.

    The increasing number of complex multi-team projects and the scarcity of knowledge about how to run them successfully, create a need for systematic empirical studies. We attempt to lessen this empirical gap by examining the overlap and structure of formally ascribed design interfaces and informal...... communication networks between participating teams in two complex multi-team projects in the space industry. We study the two projects longitudinally throughout the design and integration phases of product development. There are three major findings. First, formally ascribed design interfaces and informal...... communication networks overlap only marginally. Second, the structure of informal communication remains largely stable in the transition from the design to the integration phase. The third and most intriguing finding is that the weak overlap between formally ascribed design interfaces and the informal...

  10. Managing a complex project using a risk-risk multiple domain matrix

    International Nuclear Information System (INIS)

    Pointurier, C.; Marle, F.; Jaber, H.

    2014-01-01

    This communication aims at presenting a clustering methodology applied to a complex project consisting of the delivery of three interdependent subsystems. This enables small and complementary task forces to be constituted, enhancing the communication and coordination on transverse issues related to the complexity of the whole system. The problem is to gather and exploit data for such systems, with numerous and heterogeneous risks of different domains (product, process, organization). The method consists in regrouping actors through the clustering of the risks they own. The result is a highlight on important and transverse risk interdependencies, within and between projects. These should not be neglected in order to avoid potential severe issues, whether during the project or during the exploitation of its deliverable. An application on a real program of plant implementation in the CEA-DAM is presented, with a sensitivity analysis of the clustering results to the inputs and chosen configurations of the problem.

    Full Text Available Identity and legitimation are arguably the two most significant analytical tools required to understand religion in contemporary China. Particularly in Southwest China, the uncertainty and ambiguity in the ongoing processes of legitimizing and making ethnic identities attracts scholarship. In studying Chinese folk religion in general, Dean (2003 asserts that "local Chinese religion resists definition" (338. Pondering how to define 'religion' in the Chinese context often proves fruitless, especially in Southwest China where religious revival may involve villagers, ritual experts, monks, and government elites ranging from village heads in the margin to representatives of the Chinese state at the center. Each group holds a distinct perspective on how to legitimize ethnic and religious identities. Religious Revival is one attempt to do difficult research through an ethnographic lens. ...

    Science.gov (United States)

    Wysocki, Susan; Kingsberg, Sheryl; Krychman, Michael

    2014-01-01

    Vulvar and vaginal atrophy (VVA) is a chronic and progressive medical condition common in postmenopausal women. Symptoms of VVA such as dyspareunia, vaginal dryness, irritation, and itching can negatively impact sexual function and quality of life. The REVIVE (REal Women's VIews of Treatment Options for Menopausal Vaginal ChangEs) survey assessed knowledge about VVA and recorded attitudes about interactions with healthcare providers (HCPs) and available treatment options for VVA. The REVIVE survey identified unmet needs of women with VVA symptoms such as poor understanding of the condition, poor communication with HCPs despite the presence of vaginal symptoms, and concerns about the safety, convenience, and efficacy of available VVA treatments. HCPs can address these unmet needs by proactively identifying patients with VVA and educating them about the condition as well as discussing treatment preferences and available therapies for VVA.

  13. Periodic and quasiperiodic revivals in periodically driven interacting quantum systems

    2018-01-01

    Recently it has been shown that interparticle interactions generically destroy dynamical localization in periodically driven systems, resulting in diffusive transport and heating. In this Rapid Communication we rigorously construct a family of interacting driven systems which are dynamically localized and effectively decoupled from the external driving potential. We show that these systems exhibit tunable periodic or quasiperiodic revivals of the many-body wave function and thus of all physical observables. By numerically examining spinless fermions on a one-dimensional lattice we show that the analytically obtained revivals of such systems remain stable for finite systems with open boundary conditions while having a finite lifetime in the presence of static spatial disorder. We find this lifetime to be inversely proportional to the disorder strength.

    2011-02-01

    Tomographic techniques are used for the investigation of complex flow fields by means of deflectometric methods. A new deflection tomographic setup for obtaining an array of multidirectional deflectograms is presented. Deflection projections in different angles of view can be captured synchronously in same optical path condition and arranged on the camera in two rows with three views in each row. Tikhonov regularization method is used to reconstruct temperature distribution from deflectometric projection data. The conjugate gradient method is used to compute the regularized solution for the least-square equations. The asymmetric flame temperature distribution in the horizontal section was reconstructed from limited view angle projections. The experimental results of reconstruction from real projection data were satisfactory when compared with the direct thermocouple measurements.

  15. The Feed Materials Program of the Manhattan Project: A Foundational Component of the Nuclear Weapons Complex

    Science.gov (United States)

    Reed, B. Cameron

    2014-12-01

    The feed materials program of the Manhattan Project was responsible for procuring uranium-bearing ores and materials and processing them into forms suitable for use as source materials for the Project's uranium-enrichment factories and plutonium-producing reactors. This aspect of the Manhattan Project has tended to be overlooked in comparison with the Project's more dramatic accomplishments, but was absolutely vital to the success of those endeavors: without appropriate raw materials and the means to process them, nuclear weapons and much of the subsequent cold war would never have come to pass. Drawing from information available in Manhattan Engineer District Documents, this paper examines the sources and processing of uranium-bearing materials used in making the first nuclear weapons and how the feed materials program became a central foundational component of the postwar nuclear weapons complex.

    Localized quantum wave packets can be produced in a variety of physical systems and are the subject of much current research in atomic, molecular, chemical, and condensed-matter physics. They are particularly well suited for studying the classical limit of a quantum-mechanical system. The motion of a localized quantum wave packet initially follows the corresponding classical motion. However, in most cases the quantum wave packet spreads and undergoes a series of collapses and revivals. We pre...

    Hitherto, the language of the Methodist revival has received only moderate, and mainly descriptive, attention. A present-day study should move beyond description and approach the phenomenon from a «critical» angle, thus allowing the linguist to assess the indictments which have branded Methodist discourse as manipulative.

    Yan, Xue-Qun; Zhang, Bo-Ying

    2014-01-01

    In this paper the correlations dynamics of two atoms in the case of a micromaser-type system is investigated. Our results predict certain quasi-periodic collapse and revival phenomena for quantum discord and entanglement when the field is in Fock state and the two atoms are initially in maximally mixed state, which is a special separable state. Our calculations also show that the oscillations of the time evolution of both quantum discord and entanglement are almost in phase and they both have similar evolution behavior in some time range. The fact reveals the consistency of quantum discord and entanglement in some dynamical aspects. - Highlights: • The correlations dynamics of two atoms in the case of a micromaser-type system is investigated. • A quasi-periodic collapse and revival phenomenon for quantum discord and entanglement is reported. • A phenomenon of correlations revivals different from that of non-Markovian dynamics is revealed. • The oscillations of time evolution of both quantum discord and entanglement are almost in phase in our system. • Quantum discord and entanglement have similar evolution behavior in some time range

  19. Confucius's New Clothes: Contemporary Chinese Ideologies and the Confucian Revival

    Directory of Open Access Journals (Sweden)

    Jana S. Rošker

    2014-12-01

    Full Text Available The article introduces the ideological background of the new Confucian revival, which appeared in the P.R. China during the last two decades. Through the analysis of classical Confucianism and through the presentation of essential differences between Confucianism as a socio-ethical philosophy, which is based upon communitarian principles on the one hand, and Confucianism in the function of the official state doctrine on the other, the author clearly shows that the Confucian revival in the P.R. China is to a high degree ideologically conditioned. The article introduces two different currents within the so-called Modern Confucianism, which represents the theoretical background of this revival that has been shaped in China at the threshold of the 20th century. Whereas this stream of thought has been silenced in China already in the early 1950s, its representatives in Hong Kong and Taiwan have been further developing and upgrading the philosophical bases of this system, which is based upon various attempts to synthesize Western and traditional Chinese ideas. Only during the last two decades we could also witness a revitalization of this philosophy in the P.R. China. This revitalization, however, rests upon different foundations.

  20. Developing integrated parametric planning models for budgeting and managing complex projects

    Science.gov (United States)

    Etnyre, Vance A.; Black, Ken U.

    1988-01-01

    The applicability of integrated parametric models for the budgeting and management of complex projects is investigated. Methods for building a very flexible, interactive prototype for a project planning system, and software resources available for this purpose, are discussed and evaluated. The prototype is required to be sensitive to changing objectives, changing target dates, changing costs relationships, and changing budget constraints. To achieve the integration of costs and project and task durations, parametric cost functions are defined by a process of trapezoidal segmentation, where the total cost for the project is the sum of the various project cost segments, and each project cost segment is the integral of a linearly segmented cost loading function over a specific interval. The cost can thus be expressed algebraically. The prototype was designed using Lotus-123 as the primary software tool. This prototype implements a methodology for interactive project scheduling that provides a model of a system that meets most of the goals for the first phase of the study and some of the goals for the second phase.

    2011-01-01

    Based on the stability theory of the linear fractional order system, projective synchronization of a complex network is studied in the paper, and the coupling functions of the connected nodes are identified. With this method, the projective synchronization of the network with different fractional order chaos nodes can be achieved, besides, the number of the nodes does not affect the stability of the whole network. In the numerical simulations, the chaotic fractional order Lü system, Liu system and Coullet system are chosen as examples to show the effectiveness of the scheme. (general)

    The purpose of this paper is to describe patterns of patient safety culture that emerged from an innovative collaboration among health services researchers and fine arts colleagues. The group engaged in an arts-informed knowledge translation project to produce a dramatic expression of patient safety culture research for inclusion in a symposium. Scholars have called for a deeper understanding of the complex interrelationships among structure, process and outcomes relating to patient safety. Four patterns of patient safety culture--blinding familiarity, unyielding determination, illusion of control and dismissive urgency--are described with respect to how they informed creation of an arts-informed project for knowledge translation.

  4. The revival of the Baldwin effect

    Fontanari, José F.; Santos, Mauro

    2017-10-01

    The idea that a genetically fixed behavior evolved from the once differential learning ability of individuals that performed the behavior is known as the Baldwin effect. A highly influential paper [G.E. Hinton, S.J. Nowlan, Complex Syst. 1, 495 (1987)] claimed that this effect can be observed in silico, but here we argue that what was actually shown is that the learning ability is easily selected for. Then we demonstrate the Baldwin effect to happen in the in silico scenario by estimating the probability and waiting times for the learned behavior to become innate. Depending on parameter values, we find that learning can increase the chance of fixation of the learned behavior by several orders of magnitude compared with the non-learning situation.

  10. Structure Identification of Uncertain Complex Networks Based on Anticipatory Projective Synchronization.

    Directory of Open Access Journals (Sweden)

    Liu Heng

    Full Text Available This paper investigates a method to identify uncertain system parameters and unknown topological structure in general complex networks with or without time delay. A complex network, which has uncertain topology and unknown parameters, is designed as a drive network, and a known response complex network with an input controller is designed to identify the drive network. Under the proposed input controller, the drive network and the response network can achieve anticipatory projective synchronization when the system is steady. Lyapunov theorem and Barbǎlat's lemma guarantee the stability of synchronization manifold between two networks. When the synchronization is achieved, the system parameters and topology in response network can be changed to equal with the parameters and topology in drive network. A numerical example is given to show the effectiveness of the proposed method.

  11. Recycled Uranium Mass Balance Project Y-12 National Security Complex Site Report

    2000-12-01

    This report has been prepared to summarize the findings of the Y-12 National Security Complex (Y-12 Complex) Mass Balance Project and to support preparation of associated U. S. Department of Energy (DOE) site reports. The project was conducted in support of DOE efforts to assess the potential for health and environmental issues resulting from the presence of transuranic (TRU) elements and fission products in recycled uranium (RU) processed by DOE and its predecessor agencies. The United States government used uranium in fission reactors to produce plutonium and tritium for nuclear weapons production. Because uranium was considered scarce relative to demand when these operations began almost 50 years ago, the spent fuel from U.S. fission reactors was processed to recover uranium for recycling. The estimated mass balance for highly enriched RU, which is of most concern for worker exposure and is the primary focus of this project, is summarized in a table. A discrepancy in the mass balance between receipts and shipments (plus inventory and waste) reflects an inability to precisely distinguish between RU and non-RU shipments and receipts involving the Y-12 Complex and Savannah River. Shipments of fresh fuel (non-RU) and sweetener (also non-RU) were made from the Y-12 Complex to Savannah River along with RU shipments. The only way to distinguish between these RU and non-RU streams using available records is by enrichment level. Shipments of {le}90% enrichment were assumed to be RU. Shipments of >90% enrichment were assumed to be non-RU fresh fuel or sweetener. This methodology using enrichment level to distinguish between RU and non-RU results in good estimates of RU flows that are reasonably consistent with Savannah River estimates. Although this is the best available means of distinguishing RU streams, this method does leave a difference of approximately 17.3 MTU between receipts and shipments. Slightly depleted RU streams received by the Y-12 Complex from ORGDP and

    2017-07-01

    Full Text Available Health intervention systems are complex and subject to multiple variables in different phases of implementation. This constitutes a concrete challenge for the application of translational science in real life. Complex systems as health-oriented interventions call for interdisciplinary approaches with carefully defined system boundaries. Exploring individual components of such systems from different viewpoints gives a wide overview and helps to understand the elements and the relationships that drive actions and consequences within the system. In this study, we present an application and assessment of a framework with focus on systems and system boundaries of interdisciplinary projects. As an example on how to apply our framework, we analyzed ALERT [an integrated sensors and biosensors’ system (BEST aimed at monitoring the quality, health, and traceability of the chain of the bovine milk], a multidisciplinary and interdisciplinary project based on the application of measurable biomarkers at strategic points of the milk chain for improved food security (including safety, human, and ecosystem health (1. In fact, the European food safety framework calls for science-based support to the primary producers’ mandate for legal, scientific, and ethical responsibility in food supply. Because of its multidisciplinary and interdisciplinary approach involving human, animal, and ecosystem health, ALERT can be considered as a One Health project. Within the ALERT context, we identified the need to take into account the main actors, interactions, and relationships of stakeholders to depict a simplified skeleton of the system. The framework can provide elements to highlight how and where to improve the project development when project evaluations are required.

    2018-02-01

    NASA's Imager for Magnetopause-to-Aurora Global Exploration (IMAGE), a satellite that failed in 2005, was recently discovered to be reactivated by an amateur astronomer. Until its demise, IMAGE provided unparalleled views of solar storms crashing into Earth's magnetosphere, a capability that has not been replaced since. The amateur astronomer was on the search for Zuma, a classified U.S. satellite that's believed to have failed after launch. He instead discovered IMAGE, broadcasting again, likely thanks to a reboot that occurred after its batteries drained during a past solar eclipse. NASA scientists are now working to communicate with the satellite in the hopes of reviving its six scientific instruments.

    universe. However, it does not work within the standard model due to two reasons: (1 the strength of CP violation from the Kobayashi-Maskawa mechanism with three generations is too small; (2 the electroweak phase transition is not first order for the experimentally allowed Higgs boson mass. We discuss possibilities to solve these problems by introducing a fourth generation of fermions and how electroweak baryogenesis might be revived. We also discuss briefly the recent observation of a Higgs-like boson with mass around 125 GeV, which puts the fourth generation in a difficult situation, and the possible way out.

  16. Joint optimization scheduling for water conservancy projects in complex river networks

    2017-01-01

    Full Text Available In this study, we simulated water flow in a water conservancy project consisting of various hydraulic structures, such as sluices, pumping stations, hydropower stations, ship locks, and culverts, and developed a multi-period and multi-variable joint optimization scheduling model for flood control, drainage, and irrigation. In this model, the number of sluice holes, pump units, and hydropower station units to be opened were used as decision variables, and different optimization objectives and constraints were considered. This model was solved with improved genetic algorithms and verified using the Huaian Water Conservancy Project as an example. The results show that the use of the joint optimization scheduling led to a 10% increase in the power generation capacity and a 15% reduction in the total energy consumption. The change in the water level was reduced by 0.25 m upstream of the Yundong Sluice, and by 50% downstream of pumping stations No. 1, No. 2, and No. 4. It is clear that the joint optimization scheduling proposed in this study can effectively improve power generation capacity of the project, minimize operating costs and energy consumption, and enable more stable operation of various hydraulic structures. The results may provide references for the management of water conservancy projects in complex river networks.

    The CERN PS accelerator complex has been progressively converted to full computer controls without interrupting its full-time operation (more than 6000 hours per year with on average not more than 1% of the total down-time due to controls). The application software amounts to 120 man-years and 450'000 instructions: it compares with other large software projects, also outside the accelerator world: e.g. Skylab's ground support software. This paper outlines the application software structure which takes into account technical requirements and constraints (resulting from the complexity of the process and its operation) and economical and managerial ones. It presents the engineering and management techniques used to promote implementation, testing and commissioning within budget, manpower and time constraints and concludes with experience gained

    It is known that, after formation, a Rydberg wave packet undergoes a series of collapses and revivals within a time period called the revival time, t rev , at the end of which it is close to its original shape. We study the behavior of Rydberg wave packets on time scales much greater than t rev . We show that after a few revival cycles the wave packet ceases to reform at multiples of the revival time. Instead, a new series of collapses and revivals commences, culminating after a time period t sr >>t rev with the formation of a wave packet that more closely resembles the initial packet than does the full revival at time t rev . Furthermore, at times that are rational fractions of t sr , the square of the autocorrelation function exhibits large peaks with periodicities that can be expressed as fractions of the revival time t rev . These periodicities indicate a new type of fractional revival occurring for times much greater than t rev . A theoretical explanation of these effects is outlined. ((orig.))

  19. Collapse and revival of the Doppler-Rabi oscillations of a moving atom in a cavity

    Collapse and revival of the Doppler-Rabi oscillations of a two-level atom moving in a cavity electromagnetic field are analyzed. The coupled atom-field dynamics are predicted accurately by numerical calculation and approximately by using the stationary phase approximation combined with the Poisson summation formula. The collapse and revival patterns are shown to be qualitatively different in the cases of moving atom and atom at rest. In particular, quantum revivals of Doppler-Rabi oscillations occur with a period determined by the Doppler shift of the atomic transition frequency. This regime of Doppler-Rabi oscillations requires that the Rabi frequency and the Doppler shift satisfy the condition Ω R D . Under the inverse relation, the collapse- revival phenomenon generally does not occur. It is shown that even a small amount of atom-cavity detuning eliminates collapse-revival behavior. The analysis is performed for both coherent and thermal cavity fields

    In safety critical industries many activities are currently carried out by subcontractor networks. Nevertheless, there are few studies where the core dimensions of resilience would have been studied in safety critical network activities. This paper claims that engineering resilience into a system is largely about steering the development of culture of the system towards better ability to anticipate, monitor, respond and learn. Thus, safety culture literature has relevance in resilience engineering field. This paper analyzes practical and theoretical challenges in applying the concept of safety culture in a complex, dynamic network of subcontractors involved in the construction of a new nuclear power plant in Finland, Olkiluoto 3. The concept of safety culture is in focus since it is widely used in nuclear industry and bridges the scientific and practical interests. This paper approaches subcontractor networks as complex systems. However, the management model of the Olkiluoto 3 project is to a large degree a traditional top-down hierarchy, which creates a mismatch between the management approach and the characteristics of the system to be managed. New insights were drawn from network governance studies. - Highlights: • We studied a relevant topical subject safety culture in nuclear new build project. • We integrated safety science challenges and network governance studies. • We produced practicable insights in managing safety of subcontractor networks

    Full Text Available Was done the analysis of projects objects of trade and entertainment centers from the perspective of improving the life safety and is proposed the definition of "Trade and entertainment center", "Trade and entertainment center" and "Complex value of trade and entertainment center." A classification of shopping centers on the classification criteria and the criteria are characterized by increased security status and attractiveness of their operation. The classification of trade and entertainment centers on the criteria of classification features were made. It characterizes the security situation and will increase the attractiveness of their operation. In the nearest future the most secure and modern TEC will be those buildings who will have unique qualities such as safety systems, excellent customer service, and thus by a high level of trust (the client to the mall. The important role will play those TEC, who have clearly formed value oriented project management, including communication values using innovative methods and models. Trade and entertainment centers as an organization are included in the complex process of interaction management. They being both as an enterprise that serves the public and satisfying a great range of his interests and architectural site, which is leased and increases the business attractiveness of the district of TEC location. This duality of the essence of TEC center makes difficult to assess the effectiveness of its security.

    Previous DOE support for ''A Broad Research Program in the Sciences of Complexity'' permitted the Santa Fe Institute to initiate new collaborative research within its Integrative Core activities as well as to host visitors to participate in research on specific topics that serve as motivation and testing-ground for the study of general principles of complex systems. The critical aspect of this support is its effectiveness in seeding new areas of research. Indeed, this Integrative Core has been the birthplace of dozens of projects that later became more specifically focused and then won direct grant support independent of the core grants. But at early stages most of this multidisciplinary research was unable to win grant support as individual projects-both because it did not match well with existing grant program guidelines, and because the amount of handing needed was often too modest to justify a formal proposal to an agency. In fact, one of the attributes of core support has been that it permitted SFI to encourage high-risk activities because the cost was quite low. What is significant is how many of those initial efforts have been productive in the SFI environment. Many of SFI'S current research foci began with a short visit from a researcher new to the SFI community, or as small working groups that brought together carefully selected experts from a variety of fields.

    Engineering educators have an essential role in preparing engineers to work in a complex, interdisciplinary workforce. While much engineering education focuses on teaching students to develop disciplinary expertise in specific engineering domains, there is a strong need to teach engineers about the knowledge that they develop or use in their work (Bucciarelli 1994, Allenby Sarewitz, 2011; Frodeman, 2013). The purpose of this research is to gain a better understanding of the knowledge systems of practicing engineers through observations of their practices such that the insights learned can guide future education efforts. Using an example from a complex and interdisciplinary engineering project, this paper presents a case study overviewing the types of epistemological (or knowledge-acquiring or using) complexities that engineers navigate. Specifically, we looked at a discussion of the thermal design of a CubeSat that occurred during an engineering review at NASA. We analyzed the review using a framework that we call 'peak events', or pointed discussions between reviewers, project engineers, and managers. We examined the dialog within peak events to identify the ways that knowledge was brought to bear, highlighting discussions of uncertainty and the boundaries of knowledge claims. We focus on one example discussion surrounding the thermal design of the CubeSat, which provides a particularly thorough example of a knowledge system since the engineers present explained, justified, negotiated, and defended knowledge within a social setting. Engineering students do not get much practice or instruction in explicitly negotiating knowledge systems and epistemic standards in this way. We highlight issues that should matter to engineering educators, such as the need to discuss what level of uncertainty is sufficient and the need to negotiate boundaries of system responsibility. Although this analysis is limited to a single discussion or 'peak event', our case shows that this

    The nuclear revival is a fact, in Europe and the rest of the world. We are delighted at this. Today, all eyes are on the United Kingdom where the Government intends to do more than merely replace twenty-three aging power plants. The challenge facing them is considerable - Mr. Hutton, Britain's Minister for Trade and Industry, estimates that the work will generate 100,000 jobs. It is to be hoped that the soon-to-end Franco-British summit meeting will have strengthened understanding between the two countries. This would augur well for the French Presidency of the European Union which hopes to launch debate on a common energy policy within the European Council. Since the United Kingdom took the decision to re-launch the construction of nuclear reactors, France is no longer alone; it has a new ally in the nuclear debate. The British decision is also seen as encouraging by all the companies that wish to develop nuclear technology. This development is not only manifest in the United Kingdom; in Germany and a number of countries in Central and Eastern Europe, there is an obvious, if latent, desire to enter this sector. This document gathers the Proceedings of two symposiums: - the March 2008 conference on 'The Revival of Nuclear Energy, a challenge for the European Union' - and the November 2008 Conference on 'Nuclear safety: a worldwide Public Good'.

    Full Text Available Essential elements of the process of rural renovation programme are: stimulating activity of local communities, cooperation for development, while preserving social identity, cultural heritage and natural environment. Implementing a rural revival programme in Poland: Sectoral Operational Programme “The Restructuring and Modernisation of the Food Sector and the Development of Rural Areas in 2004-2006” (action 2.3 “Rural renovation and protection and preservation of cultural heritage” evokes criticism. A wide discussion is carried amongst researchers, politicians, social activists, and local government practitioners. The main question remains: “is rural renovation process in Poland conducted in accordance with the rules in European countries or it is only a new formula of rural modernisation with the use of European funds?” The authors are joining the discussion and in the second part of the article they are presenting the assumption of sociological research. The aim of the analysis is to grasp the essence of revitalization of rural areas located in Łódzkie voivodeship, and analyse the question of specificity of rural Revival Programmes. What is the scope and manner of use of local capital? If so, are the results obtained from implementing a rural revival programme in 2004-2006 within the scope of sustainable development? What activities are predominant in the process of project implementation? Is it rural modernisation, revitalization of the rural areas, barrier removal and change in Infrastructure, or creation of social capital and subjectivity of the local community? Has the process of rural renovation in Łódzkie voivodeship got the so called “social face” and if so, to what extent? The major assumption is that rural renovation programme in Łódzkie voivodeship relates more to revitalization material aspects than “spirituality”.

    Investment in cardiovascular drug development is on the decline as large cardiovascular outcomes trials require considerable investments in time, efforts and financial resources. Pharmacogenomics has the potential to help revive the cardiovascular drug development pipeline by providing new and better drug targets at an earlier stage and by enabling more efficient outcomes trials. This article will review some of the recent developments highlighting the value of pharmacogenomics for drug development. We discuss how genetic biomarkers can enable the conduct of more efficient clinical outcomes trials by enriching patient populations for good responders to the medication. In addition, we assess past drug development programs which support the added value of selecting drug targets that have established genetic evidence supporting the targeted mechanism of disease. Finally, we discuss how pharmacogenomics can provide valuable evidence linking a drug target to clinically relevant outcomes, enabling novel drug discovery and drug repositioning opportunities.

    Many people have projected their hopes and fears onto nuclear power. Nuclear energy has both benefits and risks, and disagreement persists about whether this energy source is, on balance, more of an asset than a liability. This debate involves a complicated set of factors that are difficult to assess, let alone fully resolve because of the differing interests in various countries' use and pursuit of nuclear power. Renewed interest throughout the globe in harnessing this energy source has stoked this perennial debate and raised concern about security threats from states and non-state actors while holding out the promise of more electricity for more people. While the motivations for nuclear energy vary among states, the two primary public goods this energy source offers are countering human-induced climate change and providing for greater energy security. Although views on how to achieve energy security differ, the essential aspect for nuclear energy is that for several countries, especially those with scarce indigenous energy sources from fossil fuels, investing in nuclear power plants diversifies electricity production portfolios and helps reduce dependence on foreign sources of energy. The focus here is on assessing the potential security consequences of increased use of nuclear power in the existing nuclear power states and most importantly in many more states that have in recent years expressed interest in this power source. The risks of nuclear power include possible reactor accidents, release of radioactive waste to the environment, attacks on or sabotage of nuclear facilities, and misuse of peaceful nuclear technologies to make nuclear weapons. While safety of nuclear plants and disposal of radioactive waste are important issues, this paper analyzes the latter two issues. In addition, it addresses two under-examined risks: military attacks on nuclear facilities and the effects on security alliances and conventional arms buildups as more countries seek to

    We present high-performance and low-complexity algorithms for real-time camera imaging applications. The main functions of the proposed camera digital signal processing (DSP) involve color interpolation, white balance, adaptive binary processing, auto gain control, and edge and color enhancement for video projection systems. A series of simulations demonstrate that the proposed method can achieve good image quality while keeping computation cost and memory requirements low. On the basis of the proposed algorithms, the cost-effective hardware core is developed using Verilog HDL. The prototype chip has been verified with one low-cost programmable device. The real-time camera system can achieve 1270 × 792 resolution with the combination of extra components and can demonstrate each DSP function.

    The present day stage of computer simulation has entered into the third phase. The age of computer simulation in plasma physics dawned in the late 1950's when Oscar Buneman and John Dawson developed the sheet particle model. In 1960's and the early part of 1970's, one devoted oneself to refine the particle model and to develop, more practically, fluid magnetic hydrodynamic models so that the feasibility of the computer simulation methodology could be tested. This age can be called 'dawning of computer simulation'. The so-called supercomputer appeared in the late 1970's and the computer simulation entered the second phase where individual nonlinear phenomena have become possible to be attacked. At present when a supercomputer with the ability of higher than 100 GFlops speed and lager than 10GBytes common memory is available, almost any individual nonlinear phenomenon, whatever it may look complex, can be solved. This age may well be called 'the age of nonlinear solver'. However, as far as the authors are satisfied with using a supercomputer for simply solving an individual nonlinear problem, the computer simulation plays only a passive role in science and would never cause a catastrophic transition to it. Then, the modern science of the 20th century based on reductionism would continue in the coming 21st century, thus the 21st century's science would stay boring and tedious. It must be the computer simulation that can refresh this boring state. At NIFS an extensive effort has been made to establish a new paradigm of science in the 21st century by developing a new synthetic methodology of computer simulation, which the authors call the MISSION Project. The authors present this MISSION Project and propose a working hypothesis of the science of complexity in this talk

  15. On projective synchronization of hyperchaotic complex nonlinear systems based on passive theory for secure communications

    2013-01-01

    In this paper we deal with the projective synchronization (PS) of hyperchaotic complex nonlinear systems and its application in secure communications based on passive theory. The unpredictability of the scaling factor in PS can additionally enhance the security of communications. In this paper, a scheme for secure message transmission is proposed, and we try to transmit more than one large or bounded message from the transmitter to the receiver. The new hyperchaotic complex Lorenz system is employed to encrypt these messages. In the transmitter, the original messages are modulated into its parameter. In the receiver, we assume that the parameter of the receiver system is uncertain. The controllers and corresponding parameter update law are constructed to achieve PS between the transmitter and receiver system with an uncertain parameter, and identify the unknown parameter via passive theory. The original messages can be recovered successfully through some simple operations by the estimated parameter. Numerical results have verified the effectiveness and feasibility of the presented method. (paper)

  16. Revivals, classical periodicity, and zitterbewegung of electron currents in monolayer graphene

    International Nuclear Information System (INIS)

    Romera, E.; Santos, F. de los

    2009-01-01

    Revivals of electric current in graphene in the presence of an external magnetic field are described. It is shown that when the electrons are prepared in the form of wave packets assuming a Gaussian population of only positive (or negative) energy Landau levels, the presence of the magnetic field induce revivals of the electron currents, besides the classical cyclotron motion. When the population comprises both positive and negative energy Landau levels, revivals of the electric current manifest simultaneously with zitterbewegung and the classical cyclotron motion. We relate the temporal scales of these three effects and discuss to what extent these results hold for real graphene samples.

    We present a theoretical study of the quantum corrections to the revival time due to finite tunneling in the collapse and revival of matter-wave interference after a quantum quench. We study hard-core bosons in a superlattice potential and the Bose-Hubbard model by means of exact numerical approaches and mean-field theory. We consider systems without and with a trapping potential present. We show that the quantum corrections to the revival time can be used to accurately determine the value of the hopping parameter in experiments with ultracold bosons in optical lattices.

    Muradyan, A Zh; Muradyan, G A

    2004-01-01

    Interaction of a lossless two-level atom with a monochromatic (classical) field of radiation is considered, as the atom initially possesses a translational state with a number of equidistant and discrete momenta. It is shown that the Rabi oscillations in such an atom evolve as a sequence of collapses and revivals, if the coupling wave deeply saturates the optical transition. Between revivals, the populations undergo subrevivals. Approximate analytical formulae are obtained taking the initial momentum distribution in the form of two shifted Gaussians or a Besselian. A possible experimental realization of such revivals is discussed

    Structural studies of multi-protein complexes, whether by X-ray diffraction, scattering, NMR spectroscopy or electron microscopy, require stringent quality control of the component samples. The inability to produce 'keystone' subunits in a soluble and correctly folded form is a serious impediment to the reconstitution of the complexes. Co-expression of the components offers a valuable alternative to the expression of single proteins as a route to obtain sufficient amounts of the sample of interest. Even in cases where milligram-scale quantities of purified complex of interest become available, there is still no guarantee that good quality crystals can be obtained. At this step, protein engineering of one or more components of the complex is frequently required to improve solubility, yield or the ability to crystallize the sample. Subsequent characterization of these constructs may be performed by solution techniques such as Small Angle X-ray Scattering and Nuclear Magnetic Resonance to identify 'well behaved' complexes. Herein, we recount our experiences gained at protein production and complex assembly during the European 3D Repertoire project (3DR). The goal of this consortium was to obtain structural information on multi-protein complexes from yeast by combining crystallography, electron microscopy, NMR and in silico modeling methods. We present here representative set case studies of complexes that were produced and analyzed within the 3DR project. Our experience provides useful insight into strategies that are more generally applicable for structural analysis of protein complexes. Copyright © 2011 Elsevier Inc. All rights reserved.

    Prior to a spacewalk during the NASA STS/129 mission in November 2009, Columbia Broadcasting System (CBS) correspondent William Harwood reported astronauts, "were awakened again", as they had been the day previously. Fearing something not properly connected was causing a leak, the crew, both on the ground and in space, stopped and checked everything. The alarm proved false. The crew did complete its work ahead of schedule, but the incident reminds us that correctly connecting hundreds and thousands of entities, subsystems and systems, finding leaks, loosening stuck valves, and adding replacements to very large complex systems over time does not occur magically. Everywhere major projects present similar pressures. Lives are at - risk. Responsibility is heavy. Large natural and human-created disasters introduce parallel difficulties as people work across boundaries their countries, disciplines, languages, and cultures with known immediate dangers as well as the unexpected. NASA has long accepted that when humans have to go where humans cannot go that simulation is the sole solution. The Agency uses simulation to achieve consensus, reduce ambiguity and uncertainty, understand problems, make decisions, support design, do planning and troubleshooting, as well as for operations, training, testing, and evaluation. Simulation is at the heart of all such complex systems, products, projects, programs, and events. Difficult, hazardous short and, especially, long-term activities have a persistent need for simulation from the first insight into a possibly workable idea or answer until the final report perhaps beyond our lifetime is put in the archive. With simulation we create a common mental model, try-out breakdowns of machinery or teamwork, and find opportunity for improvement. Lifecycle simulation proves to be increasingly important as risks and consequences intensify. Across the world, disasters are increasing. We anticipate more of them, as the results of global warming

    We study the time evolution of localized wave packets in graphene quantum dots in a perpendicular magnetic field, focusing on the quasiclassical and revival periodicities, for different values of the magnetic field intensities in a theoretical framework. We have considered contributions of the two inequivalent points in the Brillouin zone. The revival time has been found as an observable that shows the break valley degeneracy.

    2006-01-01

    Most research in the field of customer relationship management has focused on keeping existing customers. However, some companies also systematically address lost customers and try to revive these relationships. This facet of customer relationship management has been largely neglected by academic research. Our study provides a theoretical discussion and an empirical analysis of factors driving the success of relationship revival activities. Drawing on equity theory we find that the cust...

  6. The Sellafield contaminated land and groundwater management project: Characterisation of a complex nuclear facility

    Cruickshak, Julian

    2012-01-01

    The Sellafield site in North West England is one of the oldest and largest nuclear sites in the world, with a 70 year industrial history of processing and power generation. At certain points in time this industrial activity has affected the quality of land on parts of the site and one of the main tasks for Sellafield Ltd is to understand and control the legacy of ground contamination to ensure protection of the workforce, the public and the environment. Sellafield Ltd has recently completed a multi-million Pound investigation of the most complex part of the site in order to understand the impact of the various known and potential sources of contamination. The constraints of working in a challenging operational environment required both the use of tried and tested approaches and experimentation with innovative techniques. As experience was gained during implementation of the project, the characterisation plan was evolved and adapted to ensure a successful outcome. The presentation will outline the role and importance of characterising land and groundwater at Sellafield, explain how the site investigation strategy and techniques were designed to meet the challenge and describe the performance of the investigation in practice. It will conclude with a summary of how the results will be used to better support ongoing safety and environmental management and to aid the development of strategy and planning for the future.

    Okonek, Christian; Spindler, Heinz

    1980-01-01

    This expository treatment is based on a survey given by one of the authors at the Séminaire Bourbaki in November 1978 and on a subsequent course held at the University of Göttingen. It is intended to serve as an introduction to the topical question of classification of holomorphic vector bundles on complex projective spaces, and can easily be read by students with a basic knowledge of analytic or algebraic geometry. Short supplementary sections describe more advanced topics, further results, and unsolved problems. This is a corrected third printing with an Appendix by S. I. Gelfand.  ------   The present book is the first one, within the extensive literature on algebraic vector bundles, to give both a self-contained introduction to the basic methods and an exposition of the current state of the classification theory of algebraic vector bundles over Pn(C). (…) The reviewer thinks that readers should be grateful to the authors for presenting the first detailed, self-contained and systematic textbook on ve...

  8. Effective bias removal for fringe projection profilometry using the dual-tree complex wavelet transform.

    2012-08-20

    When reconstructing the three-dimensional (3D) object height profile using the fringe projection profilometry (FPP) technique, the light intensity reflected from the object surface can yield abruptly changing bias in the captured fringe image, which leads to severe reconstruction error. The traditional approach tries to remove the bias by suppressing the zero spectrum of the fringe image. It is based on the assumption that the aliasing between the frequency spectrum of the bias, which is around the zero frequency, and the frequency spectrum of the fringe is negligible. This, however, is not the case in practice. In this paper, we propose a novel (to our knowledge) technique to eliminate the bias in the fringe image using the dual-tree complex wavelet transform (DT-CWT). The new approach successfully identifies the features of bias, fringe, and noise in the DT-CWT domain, which allows the bias to be effectively extracted from a noisy fringe image. Experimental results show that the proposed algorithm is superior to the traditional methods and facilitates accurate reconstruction of objects' 3D models.

  9. The revival of General Relativity at Princeton: Daring Conservatism

    After General Relativity was established in essentially its present form in 1915 it was celebrated as a great success of mathematical physics. But the initial hopes for this theory as a basis for all of physics began to fade in the next several decades, as General Relativity was relegated to the margins of theoretical physics. Its fate began to rise in the 1950's in a revival of interest and research that over time made gravitational physics one of the hottest research topics it is today. One center of this renaissance was Princeton, where two relative newcomers explored new and different approaches to gravitational physics. Robert Dicke showed that gravity is not as inaccessible to experiment as was thought, and John Wheeler propelled it into the mainstream by proposing highly original and imaginative consequences of Einstein's theory. We will concentrate on these ideas that, in his characteristically intriguing style, Wheeler called "Daring Conservatism" - a term well known to his associates, but one he never mentioned in print. With the aid of unpublished manuscripts and notes we will explore Daring Conservatism's origin and motivation, its successes and failures, and the legacy it left behind.

    In 1891, an orthopedic surgeon in New York noted the disappearance of an inoperable sarcoma in a patient after a febrile illness. This observation resulted in experiments assessing the utility of heat therapy or thermotherapy for the treatment of cancer. While it initially fell from favor, thermotherapy has recently made a resurgence, sparking investigations into its anticancer properties. This therapy is especially attractive for glioblastoma multiforme (GBM) which is difficult to target due to the blood-brain barrier and recalcitrant to treatment. Here we briefly review the history of thermotherapy and then more methodically present the current literature as it relates to central nervous system malignancies. Recent developments show that heat is preferentially cytotoxic to tumor cells and induces cellular pathways which result in apoptotic and non-apoptotic death. Techniques to induce hyperthermia include regional hyperthermia by water bath, focused ultrasound, radiofrequency microwaves, laser-induced interstitial thermotherapy, and magnetic energy. The recent revival of these therapeutic approaches and their preliminary outcomes in the treatment of GBM is reviewed. From bacterial toxins to infusion of magnetic nanoparticles, hyperthermia has the potential to be an effective and easy-to-execute adjuvant therapy for GBM. Hyperthermia for GBM is a promising therapy as part of a growing armamentarium for malignant glioma treatment.

  12. Theology and Threshold: Victorian Approaches to Reviving Choir and Rood Screens

    Full Text Available In 1851, A. W. N. Pugin published an influential treatise on rood screens, intending in his irrepressible polemical style to create further Gothic Revival momentum for inserting these iconographically complex and liturgically vital elements into Roman Catholic and Anglican churches throughout Britain and its empire. In the decades that followed, debates regarding ritual, aesthetics, materials, and Eucharistic theology surrounded the design, presence, and indeed absence of these screens. This interdisciplinary article on the borderlands between architectural history and theology explores what was at stake in the religious symbolism of a small number of diverse screens designed by George Gilbert Scott, George Frederick Bodley, and Ninian Comper, considering them in light of the key writing produced by Pugin at the mid-point of the nineteenth century, as well as by priest–architect Ernest Geldart in the century’s end. This study, together with its three short films that explore the screens’ meanings and histories in situ, charts shifts in theology and style as each architect offered innovative views through delicate latticework of stone, paint, and wood towards the Christian sacred epicentre of the Incarnation and the sacrifice of the Eucharist.

    Full Text Available Complex Products and Systems (CoPS are high value, technology and engineering-intensive capital goods. The motivation of this study is the persistent high failure rate of CoPS projects, Asian CoPS provider’s weak capability and lack of specific research on CoPS risk management. This paper evaluates risk management maturity level of CoPS projects against a general CoPS risk management capability maturity model (RM-CMM developed by the authors. An Asian based survey was conducted to investigate the value of RM to project performance, and Asian (non-Japanese CoPS implementers’ perceived application of RM practices, their strengths and weaknesses. The survey result shows that higher RM maturity level leads to higher CoPS project performance. It also shows project complexity and uncertainty moderates the relationship between some RM practices and project performance, which implies that a contingency approach should be adopted to manage CoPS risks effectively. In addition, it shows that Asian CoPS implementers are weak in RM process and there are also rooms for improvement in the softer aspects of organizational capabilities and robustness.

  19. Lethal synergy involving bicyclomycin: an approach for reviving old antibiotics.

    One way to address the growing problem of antimicrobial resistance is to revive old compounds that may have intrinsic lethal activity that is obscured by protective factors. Bicyclomycin is an old inhibitor of the Rho transcription terminator that by itself shows little rapid lethal activity. However, bicyclomycin participates in bacteriostatic synergy, which raises the possibility that conditions for lethal synergy may exist, perhaps through a suppression of protective factors. Bicyclomycin was combined with bacteriostatic inhibitors of gene expression, and bactericidal activity was measured with several cultured Gram-negative pathogens. When used alone, bicyclomycin failed to rapidly kill growing cultures of Escherichia coli; however, the additional presence of bacteriostatic concentrations of tetracycline, chloramphenicol or rifampicin led to rapid killing. Four other pathogen species, Acinetobacter baumannii, Klebsiella pneumoniae, Salmonella enterica serotype Typhimurium and Shigella dysenteriae, also exhibited enhanced killing when bicyclomycin was combined with tetracycline or rifampicin. This lethal synergy was achieved at low concentrations (slightly above the MIC) for all agents tested in combinations. Follow-up work with E. coli indicated that lethal synergy arose from a blockage of transcription elongation. Moreover, lethal synergy was reduced when bicyclomycin was added 60 min before tetracycline, suggesting that bicyclomycin induces a protective factor. The action of bicyclomycin illustrates the potential present in a largely abandoned antibacterial agent; it exhibits lethal synergy when coadministered with known, bacteriostatic inhibitors of gene expression. The identification of protective factors, which are currently uncharacterized, may reveal new ways to promote the lethal action of some old antibiotics. © The Author 2014.

    Revival structures (rotational coherence) of three linear molecules (N 2 , O 2 , and CO 2 ) in a field free alignment condition have been investigated using high-order harmonic generation. The harmonic yields of these molecules were measured in a pump-probe manner by using a weak femtosecond (fs) laser pulse for field-free alignment of molecules and another intense fs laser pulse for harmonic generation. The harmonic intensities from 23rd to 29th order with respect to the time delay between the pump and the probe pulses showed revival structures in the condition of a field-free alignment of molecules. While the revival structure of a N 2 molecule had one-fourth the period of the full revival time and different degrees of modulation among different fractional revival times, the revival structures of O 2 and CO 2 molecules showed one-eighth the periods of the full revival time and similar degrees of modulation among all fractional revival times. The revival structures could be interpreted in terms of the nature of the highest occupied molecular orbital and the total nuclear spin.

    2002-01-01

    Using the fact that the energy eigenstates of the equilateral triangle infinite well (or billiard) are available in closed form, we examine the connections between the energy eigenvalue spectrum and the classical closed paths in this geometry, using both periodic orbit theory and the short-term semi-classical behavior of wave packets. We also discuss wave packet revivals and show that there are exact revivals, for all wave packets, at times given by T rev =9μa 2 /4(h/2π) where a and μ are the length of one side and the mass of the point particle, respectively. We find additional cases of exact revivals with shorter revival times for zero-momentum wave packets initially located at special symmetry points inside the billiard. Finally, we discuss simple variations on the equilateral (60 deg. -60 deg. -60 deg. ) triangle, such as the half equilateral (30 deg. -60 deg. -90 deg.) triangle and other 'foldings', which have related energy spectra and revival structures

    In a quantum revival, a localized wave packet re-forms or 'revives' into a compact reincarnation of itself long after it has spread in an unruly fashion over a region restricted only by the potential energy. This is a purely quantum phenomenon, which has no classical analog. Quantum revival and Anderson localization are members of a small class of subtle interference effects resulting in a quantum distribution radically different from the classical after long time evolution under classically nonlinear evolution. However, it is not clear that semiclassical methods, which start with the classical density and add interference effects, are in fact capable of capturing the revival phenomenon. Here we investigate two different one-dimensional systems, the infinite square well and Morse potential. In both the cases, after a long time the underlying classical manifolds are spread rather uniformly over phase space and are correspondingly spread in coordinate space, yet the semiclassical amplitudes are able to destructively interfere over most of coordinate space and constructively interfere in a small region, correctly reproducing a quantum revival. Further implications of this ability are discussed

    2006-01-01

    We study the revival and fractional revivals of a diatomic molecular wave packet of circular states whose weighing coefficients are peaked about a vibrational quantum number ν-bar and a rotational quantum number j-bar. Furthermore, we show that the interplay between the rotational and vibrational motion is determined by a parameter γ =√D/C, where D is the dissociation energy and C is inversely proportional to the reduced mass of the two nuclei. Using I 2 and H 2 as examples, we show, both analytically and visually (through animations), that for γ>>ν-bar, j-bar, the rotational and vibrational time scales are so far apart that the ro-vibrational motion gets decoupled and the revival dynamics depends essentially on one time scale. For γ∼ν-bar, j-bar, on the other hand, the evolution of the wave packet depends crucially on both the rotational and vibrational time scales of revival. In the latter case, an interesting rotational-vibrational fractional revival is predicted and explained

    Sea-level is expected to rise for a long time to come, even after stabilization of human-induced climatic warming. Here we use simulations with the Earth system model of intermediate complexity LOVECLIM to project sea-level changes over the third millennium forced with atmospheric greenhouse gas concentrations that stabilize by either 2000 or 2100 AD. The model includes 3D thermomechanical models of the Greenland and Antarctic ice sheets coupled to an atmosphere and an ocean model, a global glacier melt algorithm to account for the response of mountain glaciers and ice caps, and a procedure for assessing oceanic thermal expansion from oceanic heat uptake. Four climate change scenarios are considered to determine sea-level commitments. These assume a 21st century increase in greenhouse gases according to SRES scenarios B1, A1B and A2 with a stabilization of the atmospheric composition after the year 2100. One additional scenario assumes 1000 years of constant atmospheric composition from the year 2000 onwards. For our preferred model version, we find an already committed total sea-level rise of 1.1 m by 3000 AD. In experiments with greenhouse gas concentration stabilization at 2100 AD, the total sea-level rise ranges between 2.1 m (B1), 4.1 m (A1B) and 6.8 m (A2). In all scenarios, more than half of this amount arises from the Greenland ice sheet, thermal expansion is the second largest contributor, and the contribution of glaciers and ice caps is small as it is limited by the available ice volume of maximally 25 cm of sea-level equivalent. Additionally, we analysed the sensitivity of the sea-level contributions from an ensemble of nine different model versions that cover a large range of climate sensitivity realized by model parameter variations of the atmosphere–ocean model. Selected temperature indices are found to be good predictors for sea-level contributions from the different components of land ice and oceanic thermal expansion after 1000 years. (letter)

    This paper presents the results of research regarding the possibilities of the revival of the traditional Bosnian single-family house. The architectural design, spatial organization, and connection with the natural environment make it a valuable example of residential architecture. The use of local natural materials such as wood, stone, and adobe brick, brings this typology back into the limelight. This study illustrates that due to the increasing need to save energy, the importance to use natural materials, and integration of sustainable design into architectural design processes, our contemporaries turn to past examples in order to reference benchmarks combined with cutting edge technology for buildings of the future. Because Bosnia has large wooded areas, and a policy goal is to use local resources, the research aim was to establish if modern prefabricated wooden houses can reproduce traditional Bosnian architecture while meeting the highest energy efficiency requirements. Many Bosnians fear that traditional Bosnian architecture will be lost due to new construction, therefore there is opposition against the harmonization of standards. The solutions for redesigning traditional Bosnian single-family homes to meet energy efficiency requirements were obtained using the BuildOpt{sub V}IE dynamic thermal simulation software. It was used to find optimal solutions in building physics, along with several variations to be applied during construction of new buildings and reconstruction of existing buildings. This research sets a foundation for further developments in contemporary individual residences, optimized according to recent building physics standards.

    The importance of complexity in health care policy-making and interventions, as well as research and evaluation is now widely acknowledged, but conceptual confusion reigns and few applications of complexity concepts in research design have been published. Taking user fee exemption policies as an entry point, we explore the methodological consequences of 'complexity' for health policy research and evaluation. We first discuss the difference between simple, complicated and complex and introduce key concepts of complex adaptive systems theory. We then apply these to fee exemption policies. We describe how the FEMHealth research project attempts to address the challenges of complexity in its evaluation of fee exemption policies for maternal care. We present how the development of a programme theory for fee exemption policies was used to structure the overall design. This allowed for structured discussions on the hypotheses held by the researchers and helped to structure, integrate and monitor the sub-studies. We then show how the choice of data collection methods and tools for each sub-study was informed by the overall design. Applying key concepts from complexity theory proved useful in broadening our view on fee exemption policies and in developing the overall research design. However, we encountered a number of challenges, including maintaining adaptiveness of the design during the evaluation, and ensuring cohesion in the disciplinary diversity of the research teams. Whether the programme theory can fulfil its claimed potential to help making sense of the findings is yet to be tested. Experience from other studies allows for some moderate optimism. However, the biggest challenge complexity throws at health system researchers may be to deal with the unknown unknowns and the consequence that complex issues can only be understood in retrospect. From a complexity theory point of view, only plausible explanations can be developed, not predictive theories. Yet here

    We experimentally demonstrate that a processing delay, a finite response time, in the coupling can revoke the stability of the stable steady states, thereby facilitating the revival of oscillations in the same parameter space where the coupled oscillators suffered the quenching of oscillation. This phenomenon of reviving of oscillations is demonstrated using two different prototype electronic circuits. Further, the analytical critical curves corroborate that the spread of the parameter space with stable steady state is diminished continuously by increasing the processing delay. Finally, the death state is completely wiped off above a threshold value by switching the stability of the stable steady state to retrieve sustained oscillations in the same parameter space. The underlying dynamical mechanism responsible for the decrease in the spread of the stable steady states and the eventual reviving of oscillation as a function of the processing delay is explained using analytical results.

    The adaptive generalized matrix projective lag synchronization between two different complex networks with non-identical nodes and different dimensions is investigated in this paper. Based on Lyapunov stability theory and Barbalat's lemma, generalized matrix projective lag synchronization criteria are derived by using the adaptive control method. Furthermore, each network can be undirected or directed, connected or disconnected, and nodes in either network may have identical or different dynamics. The proposed strategy is applicable to almost all kinds of complex networks. In addition, numerical simulation results are presented to illustrate the effectiveness of this method, showing that the synchronization speed is sensitively influenced by the adaptive law strength, the network size, and the network topological structure.

  15. Towards a Coherent Theory of Project Alliancing: Discovering the System’s Complex Mechanisms Yielding Value for Money

    Full Text Available Alliancing is a relatively new construction project delivery method receiving increasing interest globally while also eliciting many questions about its effectiveness. That is why its operating logic should be clarified beyond the currently existing general views. Correspondingly, this paper aims to define the means and mechanisms which influence the capacity of alliancing to produce value for money. The work establishes the interlaced impact chains between formal basic solutions of alliancing and the key result areas defining the value-for-money ratio. This is made by focussing on a single alliance project and its procedural solutions and experiences. The case project of the study was an urban road tunnel under a city structure and the impact chains were explored by interviewing all eight members of the alliance leadership team covering all contracting parties. The two-stage personal interviews were conducted in accordance with the systematic modelling procedure resulting in eight cognitive maps which were then combined into a group map. The resulting model included around one hundred interlinked concepts initially, but was streamlined for the paper. Accordingly, alliancing offers a concrete framework which gives better than normal chances of success in the case of complex, challenging projects fraught with much uncertainty. Many diverse basic alliance solutions/features contribute to success, while each feature also seems to strengthen the impact of the others. This suggests that, at its best, pure project alliance is not only a coherent but also a holistic solution to challenging projects.

    We demonstrated quantum memory scheme on revival of silenced echo in orthogonal geometry in Tm3+: Y3Al5O12 crystal. The retrieval efficiency of ˜14% was demonstrated with the 36 µs storage time. In this scheme for the first time we also implemented a suppression of the revived echo signal by applying an external electric field and the echo signal has been recovered on demand if we then applied a second electric pulse with opposite polarity. This technique opens the possibilities for realizing addressing in multi-qubit quantum memory in Tm3+: Y3Al5O12 crystal.

    We have investigated quantum revivals of wave packets in a one-dimensional infinite square well potential containing a δ well in the middle. The time-dependent Schroedinger equation for this composite potential admits formally exact solutions. We present analytical results for revival properties in three physically motivated approximations: wave packets containing eigenstates with large numbers in the presence of an arbitrary δ well, 'shallow' and 'deep' δ wells. Analytical results in the case of a 'shallow' δ well have been tested numerically

    In a recent letter [J. Cardy, Phys. Rev. Lett. 112, 220401 (2014), 10.1103/PhysRevLett.112.220401], the author made a very interesting observation that complete revivals of quantum states after quantum quench can happen in a period that is a fraction of the system size. This is possible for critical systems that can be described by minimal conformal field theories with central charge c detect a regime in the phase diagram of the XY chain in which one can not determine the period of the partial revivals using the quasiparticle picture.

      This note presents a possible span of years within which the revival of the Seven against Thebes by Aeschylus took place, probably as a solitary play, by comparing two passages from the comedies of Aristophanes. In the Lysistrata, the Seven against Thebes seems not to have been given its unique...... name, but only a few years later, in the Frogs, it appears with the title known to us. The ancient claims that Aeschylus was revived at the Great Dionysia might be right.  ...

    We aimed at reviving with modern technology the paired flash-visual evoked potential (F-VEP) testing of the visual system excitability. In the 1960s, methodological problems hindered this test, which was expected to provide important physiologic information. We studied 22 consenting healthy subjects (10 men). We recorded F-VEPs from electrodes over occipital and central brain regions. We delivered single flashes, mixed at random to flash pairs at the interstimulus interval (ISI) of 333, 125, 62.5, 50, 33, and 16.5 ms, (i.e. an internal frequency (IF) of 3, 8, 16, 20, 30, and 60 Hz). Recordings were performed with the subject's eyes closed and opened. The F-VEP was split into a "main complex" and an "afterdischarge", which we analyzed statistically in relation to the eye state (closed or open) and to the changes due to paired stimulation. The eye state affected the single F-VEP size, latency and shape significantly (p<0.05). On paired stimulation, the test (second) F-VEP exhibited significant (p<0.05), ISI-dependent size changes, such as a progressive decrease for ISIs from 62.5 to 16.5 ms (IFs of 16-60 Hz), whose timing/amount varied significantly (p<0.05) according to the eye state and to the F-VEP epoch considered. Suppression of the test F-VEP was never complete, even for the shortest ISI (ISI=16.5 ms, IF=60 Hz). The eye state (closed or open) must be considered meticulously when studying F-VEPs. F-VEP changes on paired stimulation express neural inhibition within the visual system, which can be depicted as ISI-dependent curves. Modern equipment and simplified measures render this an easy test, with statistical validity, providing specific information on the excitability properties of the visual system.

  5. Risk Management in Complex Construction Projects that Apply Renewable Energy Sources: A Case Study of the Realization Phase of the Energis Educational and Research Intelligent Building

    Krechowicz, Maria

    2017-10-01

    Nowadays, one of the characteristic features of construction industry is an increased complexity of a growing number of projects. Almost each construction project is unique, has its project-specific purpose, its own project structural complexity, owner’s expectations, ground conditions unique to a certain location, and its own dynamics. Failure costs and costs resulting from unforeseen problems in complex construction projects are very high. Project complexity drivers pose many vulnerabilities to a successful completion of a number of projects. This paper discusses the process of effective risk management in complex construction projects in which renewable energy sources were used, on the example of the realization phase of the ENERGIS teaching-laboratory building, from the point of view of DORBUD S.A., its general contractor. This paper suggests a new approach to risk management for complex construction projects in which renewable energy sources were applied. The risk management process was divided into six stages: gathering information, identification of the top, critical project risks resulting from the project complexity, construction of the fault tree for each top, critical risks, logical analysis of the fault tree, quantitative risk assessment applying fuzzy logic and development of risk response strategy. A new methodology for the qualitative and quantitative risk assessment for top, critical risks in complex construction projects was developed. Risk assessment was carried out applying Fuzzy Fault Tree analysis on the example of one top critical risk. Application of the Fuzzy sets theory to the proposed model allowed to decrease uncertainty and eliminate problems with gaining the crisp values of the basic events probability, common during expert risk assessment with the objective to give the exact risk score of each unwanted event probability.

    Full Text Available In project management context, time management is one of the most important factors affecting project success. This paper proposes a new method to solve research project scheduling problems (RPSP containing Fuzzy Graphical Evaluation and Review Technique (FGERT networks. Through the deliverables of this method, a proper estimation of project completion time (PCT and success probability can be achieved. So algorithms were developed to cover all features of the problem based on three main parameters “duration, occurrence probability, and success probability.” These developed algorithms were known as PR-FGERT (Parallel and Reversible-Fuzzy GERT networks. The main provided framework includes simplifying the network of project and taking regular steps to determine PCT and success probability. Simplifications include (1 equivalent making of parallel and series branches in fuzzy network considering the concepts of probabilistic nodes, (2 equivalent making of delay or reversible-to-itself branches and impact of changing the parameters of time and probability based on removing related branches, (3 equivalent making of simple and complex loops, and (4 an algorithm that was provided to resolve no-loop fuzzy network, after equivalent making. Finally, the performance of models was compared with existing methods. The results showed proper and real performance of models in comparison with existing methods.

    A concourse of low-power NPP was conducted in Russia in 1994. It was conducted under the aegis of Nuclear Association of Russia. The projects of three reactor power groups were considered: less than 10 MW (t), from 10 to 50 MW (t) and more than 50 MW (t). More than 20 projects were presented. In the third power group the best was the project KLT-40. The reactor is manufactured production-run for nuclear-powered icebreakers, and underwent public and international examination. It was recommended to give preference to floating power units (FPU) at selecting of a location option for a definite Customer under other equal conditions for remote state regions. Simultaneously with the concourse the market for low-power NPP was researched. Technical-economical reports on Chukotski autonomous region, Primorski and Khabarovski regions and other remote regions of the North and North East of the state were made. At considering of an issue of low-power NPP usage for the North of Russia more than 250 points were examined. As a result of conducted analysis were selected 26 promising points for location of low-power NPP. Preliminary analysis of low-power NPP development projects efficiency earnestly showed their high competitiveness in comparison with standard power-suppliers in remote regions of Russia, even at presence of proper energy carriers.

    Full Text Available This paper describes a research project, aimed at developing a system to integrate RFID-based materials management with resources modelling in project management to improve on-site materials tracking and inventory management processes. In order to develop the system, a comprehensive literature review and exploratory case studies were conducted to investigate current practices, problems, implementation of ICT and potential use of emerging technologies (such as RFID and wireless technologies in overcoming the logistical difficulties associated with materials management. An initial assessment revealed that there is a potential to improve the tracking and management of materials using modern ICT, thus will enhance the operational efficiency of the project delivery process. Moreover, sophisticated technologies such as wireless systems and tagging are not generally used to overcome human error in materials identification and the space constraints inherent in many projects. This paper concludes the finding from case studies for developing a real-time materials tracking framework to support construction professional in handling materials more effectively.

    The Eastern Quebec Telepathology Network (EQTN) has been implemented in the province of Quebec (Canada) to support pathology and surgery practices in hospitals that are lack of pathologists, especially in rural and remote areas. This network includes 22 hospitals and serves a population of 1.7 million inhabitants spread over a vast territory. An evaluation of this network was conducted in order to identify and analyze the factors and issues associated with its implementation and deployment, as well as those related to its sustainability and expansion. Qualitative evaluative research based on a case study using: (1) historical analysis of the project documentation (newsletters, minutes of meetings, articles, ministerial documents, etc); (2) participation in meetings of the committee in charge of telehealth programs and the project; and (3) interviews, focus groups, and discussions with different stakeholders, including decision-makers, clinical and administrative project managers, clinicians (pathologists and surgeons), and technologists. Data from all these sources were cross-checked and synthesized through an integrative and interpretative process. The evaluation revealed numerous socio-political, regulatory, organizational, governance, clinical, professional, economic, legal and technological challenges related to the emergence and implementation of the project. In addition to technical considerations, the development of this network was associated with major changes and transformations of production procedures, delivery and organization of services, clinical practices, working methods, and clinicaladministrative processes and cultures (professional/organizational). The EQTN reflects the complex, structuring, and innovative projects that organizations and health systems are required to implement today. Future works should be more sensitive to the complexity associated with the emergence of telehealth networks and no longer reduce them to technological

    Fundamental changes in the hydrological cycle are expected in a future warmer climate. This is of particular relevance for the Alpine region, as a source and reservoir of several major rivers in Europe and being prone to extreme events such as floodings. For this region, climate change assessments based on the ENSEMBLES regional climate models (RCMs) project a significant decrease in summer mean precipitation under the A1B emission scenario by the mid-to-end of this century, while winter mean precipitation is expected to slightly rise. From an impact perspective, projected changes in seasonal means, however, are often insufficient to adequately address the multifaceted challenges of climate change adaptation. In this study, we revisit the full matrix of the ENSEMBLES RCM projections regarding changes in frequency and intensity, precipitation-type (convective versus stratiform) and temporal structure (wet/dry spells and transition probabilities) over Switzerland and surroundings. As proxies for raintype changes, we rely on the model parameterized convective and large-scale precipitation components. Part of the analysis involves a Bayesian multi-model combination algorithm to infer changes from the multi-model ensemble. The analysis suggests a summer drying that evolves altitude-specific: over low-land regions it is associated with wet-day frequency decreases of convective and large-scale precipitation, while over elevated regions it is primarily associated with a decline in large-scale precipitation only. As a consequence, almost all the models project an increase in the convective fraction at elevated Alpine altitudes. The decrease in the number of wet days during summer is accompanied by decreases (increases) in multi-day wet (dry) spells. This shift in multi-day episodes also lowers the likelihood of short dry spell occurrence in all of the models. For spring and autumn the combined multi-model projections indicate higher mean precipitation intensity north of the

    Climate change has become one of the most significant environmental issues, of which about 40% come from the building sector. In particular, complex building projects with various functions have increased, which should be managed from a program-level perspective. Therefore, this study aimed to develop a program-level management system for the life-cycle environmental and economic assessment of complex building projects. The developed system consists of three parts: (i) input part: database server and input data; (ii) analysis part: life cycle assessment and life cycle cost; and (iii) result part: microscopic analysis and macroscopic analysis. To analyze the applicability of the developed system, this study selected ‘U’ University, a complex building project consisting of research facility and residential facility. Through value engineering with experts, a total of 137 design alternatives were established. Based on these alternatives, the macroscopic analysis results were as follows: (i) at the program-level, the life-cycle environmental and economic cost in ‘U’ University were reduced by 6.22% and 2.11%, respectively; (ii) at the project-level, the life-cycle environmental and economic cost in research facility were reduced 6.01% and 1.87%, respectively; and those in residential facility, 12.01% and 3.83%, respective; and (iii) for the mechanical work at the work-type-level, the initial cost was increased 2.9%; but the operation and maintenance phase was reduced by 20.0%. As a result, the developed system can allow the facility managers to establish the operation and maintenance strategies for the environmental and economic aspects from a program-level perspective. - Highlights: • A program-level management system for complex building projects was developed. • Life-cycle environmental and economic assessment can be conducted using the system. • The design alternatives can be analyzed from the microscopic perspective. • The system can be used to

In particular, complex building projects with various functions have increased, which should be managed from a program-level perspective. Therefore, this study aimed to develop a program-level management system for the life-cycle environmental and economic assessment of complex building projects. The developed system consists of three parts: (i) input part: database server and input data; (ii) analysis part: life cycle assessment and life cycle cost; and (iii) result part: microscopic analysis and macroscopic analysis. To analyze the applicability of the developed system, this study selected ‘U’ University, a complex building project consisting of research facility and residential facility. Through value engineering with experts, a total of 137 design alternatives were established. Based on these alternatives, the macroscopic analysis results were as follows: (i) at the program-level, the life-cycle environmental and economic cost in ‘U’ University were reduced by 6.22% and 2.11%, respectively; (ii) at the project-level, the life-cycle environmental and economic cost in research facility were reduced 6.01% and 1.87%, respectively; and those in residential facility, 12.01% and 3.83%, respective; and (iii) for the mechanical work at the work-type-level, the initial cost was increased 2.9%; but the operation and maintenance phase was reduced by 20.0%. As a result, the developed system can allow the facility managers to establish the operation and maintenance strategies for the environmental and economic aspects from a program-level perspective. - Highlights: • A program-level management system for complex building projects was developed. • Life-cycle environmental and economic assessment can be conducted using the system. • The design alternatives can be analyzed from the microscopic perspective. • The system can be used to

    The Cultural and sport complex of La Peche is a new construction project which in its first phase will consist of an arena and a community room. The second phase will include a swimming pool and curling facilities. A description of the complex was provided in this paper, including details of square footage, seating, offices and service rooms. An energy consumption analysis was conducted, with details of mechanical and electrical installations, refrigeration system options, and a complete list of architectural options with reference to the commercial building incentive program. Detailed evaluations of scenarios were provided. A reference model was provided with details of standard operational data concerning issues such as lighting density and resurfacings. Two types of heating systems were simulated in the reference model: electric and natural gas with details of consumption levels estimated for both. Later modifications to the reference model were made concerning energy efficiency saving measures. Three compressor types were also evaluated: modular, screw and reciprocating. The most profitable measures reviewed in this document were the following: radiant floor heating; make-up air recovery; central management systems; smaller secondary refrigerant fluid pumps and a low emissivity ceiling. A 20 year period life cycle cost comparison revealed that the complex would recover 20 per cent of the energy rejected by compressors. The use of a 100 per cent heat recovery system would result in savings of $33,962 per year. tabs., figs.

  1. Collapse and revival of the Fermi sea in a Bose-Fermi mixture

    The collapse and revival of quantum fields is one of the most pristine forms of coherent quantum dynamics far from equilibrium. Until now, it has only been observed in the dynamical evolution of bosonic systems. We report on the first observation of the boson mediated collapse and revival of the Fermi sea in a Bose-Fermi mixture. Specifically, we present a simple model which captures the experimental observations shown in the talk titled Observation of Collapse and Revival Dynamics in the Fermionic Component of a Lattice Bose-Fermi Mixture by Sebastian Will. Our theoretical analysis shows why the results are robust to the presence of harmonic traps during the loading or the time evolution phase. It also makes apparent that the fermionic dynamics is independent of whether the bosonic component consists of a coherent state or localized Fock states with random occupation numbers. Because of the robustness of the experimental results, we argue that this kind of collapse and revival experiment can be used to accurately characterize interactions between bosons and fermions in a lattice.

    We propose a protocol for the simultaneous controlled creation of multiple concentric ring dark solitons in a toroidally trapped flat Bose–Einstein condensate. The decay of these solitons into a vortex–antivortex necklace shows revivals of the soliton structure, but eventually becomes an example of quantum turbulence. (fast track communications)

    Full Text Available This paper provides an overview of the educational process of telecommunication engineering students by presenting the preparation of a team project focused on information security. Our educational approach combines basic knowledge such as mathematics with specialized engineering notions and various skills. The project theme is to design, implement and test an encryption algorithm. Students are provided with online courses, specific software programs and Internet access. They have to choose an encryption algorithm, to study its details and to write the script of the encryption algorithm in MATLAB program. The algorithm is implemented in C/C++ programming language and tested. Finally, a concurrent team tries to break the algorithm by finding the decryption key. It is an interactive approach which combines various education methods including gaming concepts. The covered topics provide students professional outcomes such as knowledge and use of specific mathematical tools and software environments (C/C ++ programming languages, MATLAB, abilities to design, develop, implement and test software algorithms. The project also provides transversal outcomes such as ability to team work, skills of computer use and information technology and capability to take responsibilities. Creativity is also encouraged by extending the algorithm to other encryption key lengths than the usual ones.

    Full Text Available Following previous works for the unit ball due to Nikolai Vasilevski, we define quasi-radial pseudo-homogeneous symbols on the projective space and obtain the corresponding commutativity results for Toeplitz operators. A geometric interpretation of these symbols in terms of moment maps is developed. This leads us to the introduction of a new family of symbols, extended pseudo-homogeneous, that provide larger commutative Banach algebras generated by Toeplitz operators. This family of symbols provides new commutative Banach algebras generated by Toeplitz operators on the unit ball.

    Full Text Available Low-cost housing which has been disposed of by private owners is extremely difficult for conveyancers to register. The law as it stands is often incapable of giving effect to the business transactions of the poor, thereby creating insecurity of tenure nationwide. The Land Titles Adjustment Act 111 of 1993 is currently the only legislation capable of dealing with this impasse. The Overstrand Municipality has provided the staff and infrastructure to run a pilot project under the Act, for which it is awaiting confirmation from the Department of Rural Development and Land Reform. This article discusses the legal issues arising and the potential of such an initiative to provide consumer protection for the low-literate and other vulnerable holders of rights.

    Cancer care is highly complex and suffers from fragmentation and lack of coordination across provider specialties and clinical domains. As a result, patients often find that they must coordinate care on their own. Coordinated delivery teams may address these challenges and improve quality of cancer care. Task interdependence is a core principle of rigorous teamwork and is essential to addressing the complexity of cancer care, which is highly interdependent across specialties and modalities. We examined challenges faced by a patient with early-stage breast cancer that resulted from difficulties in understanding and managing task interdependence across clinical domains involved in this patient's care. We used team science supported by the project management discipline to discuss how various task interdependence aspects can be recognized, deliberately designed, and systematically managed to prevent care breakdowns. This case highlights how effective task interdependence management facilitated by project management methods could markedly improve the course of a patient's care. This work informs efforts of cancer centers and practices to redesign cancer care delivery through innovative, practical, and patient-centered approaches to management of task interdependence in cancer care. Future patient-reported outcomes research will help to determine optimal ways to engage patients, including those who are medically underserved, in managing task interdependence in their own care.

    Cognitive reserve hypothesis predicts that intellectually demanding activities over the life course protect against dementia. We investigate if childhood school performance remains associated with dementia once education and occupational complexity are taken into account. A cohort of 440 individuals aged 75+ from the Kungsholmen Project was followed up for 9 years to detect dementia. To measure early-life contributors to reserve, we used grades at age 9-10 extracted from the school archives. Data on formal education and occupational complexity were collected at baseline and first follow-up. Dementia was ascertained through comprehensive clinical examination. Cox models estimated the relationship between life-course cognitive reserve measures and dementia. Dementia risk was elevated [hazard ratio (HR): 1.54, 95% confidence interval (CI): 1.03 to 2.29] in individuals with low early-life school grades after adjustment for formal educational attainment and occupational complexity. Secondary education was associated with a lower risk of dementia (HR: 0.72, 95% CI: 0.50 to 1.03), although the effects of post-secondary and university degrees were indistinguishable from baseline. Occupational complexity with data and things was not related to dementia. However, an association was found between high occupational complexity with people and dementia, albeit only in women (HR: 0.39, 95% CI: 0.14 to 0.99). The pattern of results remained unchanged after adjustment for genetic susceptibility, comorbidities and depressive symptoms. Low early-life school performance is associated with an elevated risk of dementia, independent of subsequent educational and occupational attainment. © The Author 2016; all rights reserved.

    Acute heart failure (AHF) is the leading cause of hospital admission among older Americans. The Randomized EValuation of Intravenous Levosimendan Efficacy (REVIVE II) trial compared patients randomly assigned to a single infusion of levosimendan (levo) or placebo (SOC), each in addition to local standard treatments for AHF. We report an economic analysis of REVIVE II from the hospital perspective. REVIVE II enrolled patients (N = 600) hospitalized for treatment of acute decompensated heart failure (ADHF) who remained dyspneic at rest despite treatment with intravenous diuretics. Case report forms documented index hospital treatment (drug administration, procedures, days of treatment by care unit), as well as subsequent hospital and emergency department admissions during follow-up ending 90 days from date of randomization. These data were used to impute cost of admission based on an econometric cost function derived from >100,000 ADHF hospital billing records selected per REVIVE II inclusion criteria. Index admission mean length of stay (LOS) was shorter for the levo group compared with standard of care (SOC) (7.03 vs 8.96 days, P = 0.008) although intensive care unit (ICU)/cardiac care unit (CCU) days were similar (levo 2.88, SOC 3.22, P = 0.63). Excluding cost for levo, predicted mean (median) cost for the index admission was levo US $13,590 (9,458), SOC $19,021 (10,692) with a difference of $5,431 (1,234) favoring levo (P = 0.04). During follow-up through end of study day 90, no significant differences were observed in numbers of hospital admissions (P = 0.67), inpatient days (P = 0.81) or emergency department visits (P = 0.41). Cost-effectiveness was performed with a REVIVE-II sub-set conforming to current labeling, which excluded patients with low baseline blood pressure. Assuming an average price for levo in countries where currently approved, there was better than 50% likelihood that levo was both cost-saving and improved survival. Likelihood that levo would

    While global climate models (GCMs) provide useful projections of near-surface wind vectors into the 21st century, resolution is not sufficient enough for use in regional wave modeling. Statistically downscaled GCM projections from Multivariate Adaptive Constructed Analogues provide daily averaged near-surface winds at an appropriate spatial resolution for wave modeling within the orographically complex region of San Francisco Bay, but greater resolution in time is needed to capture the peak of storm events. Short-duration high wind speeds, on the order of hours, are usually excluded in statistically downscaled climate models and are of key importance in wave and subsequent coastal flood modeling. Here we present a temporal downscaling approach, similar to constructed analogues, for near-surface winds suitable for use in local wave models and evaluate changes in wind and wave conditions for the 21st century. Reconstructed hindcast winds (1975–2004) recreate important extreme wind values within San Francisco Bay. A computationally efficient method for simulating wave heights over long time periods was used to screen for extreme events. Wave hindcasts show resultant maximum wave heights of 2.2 m possible within the Bay. Changes in extreme over-water wind speeds suggest contrasting trends within the different regions of San Francisco Bay, but 21th century projections show little change in the overall magnitude of extreme winds and locally generated waves.

A project offering new socioeconomic perspectives to the European citizens and an attractive utopia. This text will take place in four phases. In a first part, we shall describe the exhaustion of paradigm liberal and the limits of paradigm keynesian. Secondly, we shall try hard to demonstrate the theoretical possibility of establishing new one paradigm.

    A Vancouver, British Columbia, independent and its Sudanese partner have filed a development plan with the government of Sudan to produce an initial 40,000 b/d from Heglig and Unity oil fields in Sudan. Arakis Energy Corp., and the private Sudanese company State Petroleum Corp. (SPC) want to begin the first commercial hydrocarbon production in the destitute, war torn country. They are picking up where Chevron Corp. left off after years of grappling with an ambitious, costly - and ultimately futile - effort to export crude-oil from Sudan. After finding almost 300 million bbl of oil in Sudan during the early 1980s, Chevron scuttled a $2 billion project to export 50,000 b/d of Sudanese crude in 1986. It drilled 90 wells and sank more than $1 billion into the project. But it dropped the plan, citing the 1986 collapse of oil prices and concerns over security after repeated guerrilla attacks delayed work. The paper details the project

    We demonstrate a quantum walk with time-dependent coin bias. With this technique we realize an experimental single-photon one-dimensional quantum walk with a linearly ramped time-dependent coin flip operation and thereby demonstrate two periodic revivals of the walker distribution. In our beam-displacer interferometer, the walk corresponds to movement between discretely separated transverse modes of the field serving as lattice sites, and the time-dependent coin flip is effected by implementing a different angle between the optical axis of half-wave plate and the light propagation at each step. Each of the quantum-walk steps required to realize a revival comprises two sequential orthogonal coin-flip operators, with one coin having constant bias and the other coin having a time-dependent ramped coin bias, followed by a conditional translation of the walker.

  1. Perceptions of dyspareunia in postmenopausal women with vulvar and vaginal atrophy: findings from the REVIVE survey.

    Science.gov (United States)

    Freedman, Murray A

    2014-07-01

    Symptoms of vulvar and vaginal atrophy (VVA), including dyspareunia and vaginal dryness, have a distinct negative impact on a woman's quality of life. The REVIVE survey highlighted the lack of awareness of VVA symptoms among postmenopausal women with vaginal symptoms, with many women reluctant to initiate discussions with their healthcare professionals despite the presence of vaginal symptoms. The REVIVE survey also provided insights into women's views of VVA treatments. Women reported displeasure with the vaginal administration route, lack of symptom relief with over-the-counter products, and concerns about the safety of estrogen therapies. With the high prevalence of VVA, obstetricians/gynecologists should become vigilant in identifying women with VVA by implementing screening and discussion of symptoms during routine office visits - providing patients with information about appropriate therapies based on the severity and impact of symptoms, keeping in mind individual preferences and perceptions.

    2016-05-01

    Despite continuing for over two decades, the debate about the nature of the trends in religiosity in post-Communist Eastern Europe remains unresolved: some arguing that these countries are undergoing the same process of secularization as the West, while others insist that the entire region is experiencing a religious revival. Using national sample surveys from the early 1990s to 2007 to examine the change in demographic predictors of religiosity, we show that Catholic and Orthodox countries are experiencing different trends, the first group displaying evidence of secularization and the second of revival, and that these two different trends are likely to derive from the legacies of state repression and the differing abilities of the churches to resist such repression. We argue that the current literature has thus taken a mistakenly general approach, and that the post-Communist region consists of at least two distinct groups of societies with different trends in religiosity.

    We study quantum wave packet revivals on two-dimensional infinite circular quantum wells (CQWs) and circular quantum dots with position-dependent mass (PDM) envisaging a possible experimental realization. We consider CQWs with radially varying mass, addressing particularly the cases where M(r){proportional_to}r{sup w} with w=1,2, or -2. The two PDM Hamiltonians currently allowed by theory were analyzed and we were able to construct a strong theoretical argument favoring one of them.

  8. Entanglement revival can occur only when the system-environment state is not a Markov state

    Sargolzahi, Iman

    2018-06-01

    Markov states have been defined for tripartite quantum systems. In this paper, we generalize the definition of the Markov states to arbitrary multipartite case and find the general structure of an important subset of them, which we will call strong Markov states. In addition, we focus on an important property of the Markov states: If the initial state of the whole system-environment is a Markov state, then each localized dynamics of the whole system-environment reduces to a localized subdynamics of the system. This provides us a necessary condition for entanglement revival in an open quantum system: Entanglement revival can occur only when the system-environment state is not a Markov state. To illustrate (a part of) our results, we consider the case that the environment is modeled as classical. In this case, though the correlation between the system and the environment remains classical during the evolution, the change of the state of the system-environment, from its initial Markov state to a state which is not a Markov one, leads to the entanglement revival in the system. This shows that the non-Markovianity of a state is not equivalent to the existence of non-classical correlation in it, in general.

  9. Thermalization and revivals after a quantum quench in conformal field theory.

    2014-06-06

    We consider a quantum quench in a finite system of length L described by a 1+1-dimensional conformal field theory (CFT), of central charge c, from a state with finite energy density corresponding to an inverse temperature β≪L. For times t such that ℓ/2revivals at which F is O(1), leading to an eventual complete revival with F=1. There is also interesting structure at all rational values of t/L, related to properties of the CFT under modular transformations. At early times t≪(Lβ)^{1/2} there is a universal decay F∼exp(-(πc/3)Lt^{2}/β(β^{2}+4t^{2})). The effect of an irrelevant nonintegrable perturbation of the CFT is to progressively broaden each revival at t=nL/2 by an amount O(n^{1/2}).

    The purpose of this study was to evaluate the safety and technical feasibility of a new thrombectomy device (Revive; Micrus Endovascular) in the endovascular treatment of acute ischemic stroke. Ten patients with acute large vessel occlusions were treated with the Revive device between October 2010 and December 2010. Mean National Institutes of Health Stroke Scale on admission was 19.0; mean duration of symptoms was 172 minutes. Recanalization was assessed using the Thrombolysis In Cerebral Infarction score. Clinical outcome (National Institutes of Health Stroke Scale) after thrombectomy was determined on Day 1, at discharge, and at Day 30. Vessel recanalization (Thrombolysis In Cerebral Infarction 2b or 3) was successful in all patients without device-related complications. Mean National Institutes of Health Stroke Scale 24 hours after the intervention, at discharge, and at Day 30 was 14.0, 11.5, and 5.1, respectively. At Day 30, 6 patients had a clinical improvement of >8 points or an National Institutes of Health Stroke Scale of 0 to 1, 1 patient showed minor improvement, and 3 patients had died. Symptomatic intracranial hemorrhage occurred in 2 patients, of which 1 was fatal. Thrombectomy with the Revive device in patients with stroke with acute large vessel occlusions demonstrated to be technically safe and highly effective. Clinical safety and efficacy have to be established in larger clinical trials.

    Based on the time-convolutionless master-equation approach, we investigate the squeezing dynamics of two atoms in dissipative cavities. We find that the atomic squeezing is related to initial atomic states, atom–cavity couplings, non-Markovian effects and resonant frequencies of an atom and its cavity. The results show that a collapse–revival phenomenon will occur in the atomic squeezing and this process is accompanied by the buildup and decay of entanglement between two atoms. Enhancing the atom–cavity coupling can increase the frequency of the collapse–revival of the atomic squeezing. The stronger the non-Markovian effect is, the more obvious the collapse–revival phenomenon is. In particular, if the atom–cavity coupling or the non-Markovian effect is very strong, the atomic squeezing will tend to a stably periodic oscillation in a long time. The oscillatory frequency of the atomic squeezing is dependent on the resonant frequency of the atom and its cavity. (paper)

    We describe the temporal behavior of the dynamic elements of an exactly soluble quantum model. The model consists of a single two-level atom or spin interacting with a single mode of the quantized radiation field in the dipole approximation, the mode being initially in an arbitrary coherent state of excitation. We give new long-time numerical and closed-form approximate analytic solutions for the expectation values of the atomic dipole moment and the difference in population of the two atomic levels in the rotating wave approximation. The atomic dipole-dipole correlation function is calculated. All of the results are obtained without semiclassical or decorrelation approximations. Unusual features found in the temporal behavior of this lossless model problem are ''collapse,'' i.e., episodic nonexponential damping of both the atomic inversion and dipole moment, and two kinds of ''revival'' or partial recorrelation, in the dynamic evolution, during which the initial state is nearly recovered. We give analytic formulas for the collapse function, for both of the revival times, and for the envelope of the revival maxima. Some remarks are made about the nature of irreversibility in this exactly soluble and loss-free model

    Highlights: • The phenomena of suppression and revival of oscillations are studied in indirectly coupled nonlinear oscillators. • The decay parameter and a feedback factor play a crucial role in emergent dynamical behavior of oscillators. • The critical curves for different dynamical regions are obtained analytically using linear stability analysis. • Electronic circuit experiments demonstrate these emergent dynamical states. - Abstract: We study the phenomena of suppression and revival of oscillations in a system of limit cycle oscillators coupled indirectly via a dynamic local environment. The dynamics of the environment is assumed to decay exponentially with time. We show that for appropriate coupling strength, the decay parameter of the environment plays a crucial role in the emergent dynamics such as amplitude death (AD) and oscillation death (OD). We also show that introducing a feedback factor in the diffusion term revives the oscillations in this system. The critical curves for the regions of different emergent states as a function of coupling strength, decay parameter of the environment and feedback factor in the coupling are obtained analytically using linear stability analysis. These results are found to be consistent with the numerics and are also observed experimentally.

    The effects of wave packet collapse and revival in monolayer and bilayer graphene at an external perpendicular magnetic field are described. The evolution of electron wave packets, which are a superposition of the states with quantum numbers n around that of some Landau level n 0 was studied. The probability densities as well as average velocities of the packet center were calculated analytically and then visualized. The initial wave packet consisting only of positive energy decomposed into several subpackets at the moments t = (m/n)T R , where T R is the revival time and m, n are the mutually prime integers. Besides, it is shown that the behavior of a wave packet containing the states of both energy bands (with E n > 0 and E n < 0) is more complicated. Such packet splits into two parts, which rotate with a cyclotron frequency in the opposite directions, and then experience collapse and revival. The structure of multipole electromagnetic radiation of these packets is analyzed.

    We consider an array of l b Cooper pair boxes, each of which is coupled to a superconducting reservoir by a capacitive tunnel junction. We discuss two effects that probe not just the quantum nature of the islands, but also of the superconducting reservoir coupled to them. These are analogues to the well-known quantum optical effects 'superradiance' and 'revival'. When revival is extended to multiple systems, we find that 'entanglement revival' can also be observed. In order to study the above effects, we utilize a highly simplified model for these systems in which all the single-electron energy eigenvalues are set to be the same (the strong coupling limit), as are the charging energies of the Cooper pair boxes, allowing the whole system to be represented by two coupled quantum spins, one finite, which represents the array of boxes, and one representing the reservoir, which we consider in the limit of infinite size. Although this simplification is drastic, the model retains the main features necessary to capture the phenomena of interest. Given the progress in superconducting box experiments over recent years, it is possible that experiments to investigate both of these interesting quantum coherent phenomena could be performed in the foreseeable future

    A gamma camera has been updated and converted to serve as a demonstrator for educational purposes. The gantry and the camera head were the only part of the system that remained untouched. The main reason for this modernization was to increase the transparency of the gamma camera by partitioning the different logical building blocks of the system and thus providing access for inspection and improvements throughout the chain. New data acquisition and reconstruction software has been installed. By taking these measures, the camera is now used in education and also serves as a platform for tests of new hardware and software solutions. The camera is also used to demonstrate 3D (SPECT) imaging by collecting 2D projections from a rotatable cylindrical phantom. Since the camera head is not attached mechanically to the phantom, the effect of misalignment between the head and the rotation axis of the phantom can be studied.

    2012-07-01

    Full Text Available Quantitative retrieval of land surface biological parameters (e.g. foliage projective cover [FPC] and Leaf Area Index is crucial for forest management, ecosystem modelling, and global change monitoring applications. Currently, remote sensing is a widely adopted method for rapid estimation of surface biological parameters in a landscape scale. Topographic correction is a necessary pre-processing step in the remote sensing application for topographically complex terrain. Selection of a suitable topographic correction method on remotely sensed spectral information is still an unresolved problem. The purpose of this study is to assess the impact of topographic corrections on the prediction of FPC in hilly terrain using an established regression model. Five established topographic corrections [C, Minnaert, SCS, SCS+C and processing scheme for standardised surface reflectance (PSSSR] were evaluated on Landsat TM5 acquired under low and high sun angles in closed canopied subtropical rainforest and eucalyptus dominated open canopied forest, north-eastern Australia. The effectiveness of methods at normalizing topographic influence, preserving biophysical spectral information, and internal data variability were assessed by statistical analysis and by comparing field collected FPC data. The results of statistical analyses show that SCS+C and PSSSR perform significantly better than other corrections, which were on less overcorrected areas of faintly illuminated slopes. However, the best relationship between FPC and Landsat spectral responses was obtained with the PSSSR by producing the least residual error. The SCS correction method was poor for correction of topographic effect in predicting FPC in topographically complex terrain.

    Using Isham's group-theoretic quantization scheme, we construct the canonical groups of the systems on the two-dimensional sphere and one-dimensional complex projective space, which are homeomorphic. In the first case, we take SO(3) as the natural canonical Lie group of rotations of the two-sphere and find all the possible Hamiltonian vector fields, and followed by verifying the commutator and Poisson bracket algebra correspondences with the Lie algebra of the group. In the second case, the same technique is resumed to define the Lie group, in this case SU (2), of CP'.We show that one can simply use a coordinate transformation from S 2 to CP 1 to obtain all the Hamiltonian vector fields of CP 1 . We explicitly show that the Lie algebra structures of both canonical groups are locally homomorphic. On the other hand, globally their corresponding canonical groups are acting on different geometries, the latter of which is almost complex. Thus the canonical group for CP 1 is the double-covering group of SO(3), namely SU(2). The relevance of the proposed formalism is to understand the idea of CP 1 as a space of where the qubit lives which is known as a Bloch sphere

  1. How to revive breakthrough innovation in the pharmaceutical industry.

    Munos, Bernard H; Chin, William W

    2011-06-29

    Over the past 20 years, pharmaceutical companies have implemented conservative management practices to improve the predictability of therapeutics discovery and success rates of drug candidates. This approach has often yielded compounds that are only marginally better than existing therapies, yet require larger, longer, and more complex trials. To fund them, companies have shifted resources away from drug discovery to late clinical development; this has hurt innovation and amplified the crisis brought by the expiration of patents on many best-selling drugs. Here, we argue that more breakthrough therapeutics will reach patients only if the industry ceases to pursue "safe" incremental innovation, re-engages in high-risk discovery research, and adopts collaborative innovation models that allow sharing of knowledge and costs among collaborators.

    Full Text Available Architecture is the art and science of designing which involves the manipulation of mass, space, volume, texture, light, shadow, materials, program and other elements in order to achieve an end which is aesthetic, functional and sustainable. Sustainability is a growing trend within the field of architecture, it is currently the most pressing, complex and challenging agenda facing architects. The industrialization and modernization of the world has led to increased initiatives regarding sustainability debate, where recently the word ‘sustainable’ entered into the consciousness of architects and became an essential concern in the discourse of architecture. What is more, we are nowadays witnessing the defense of former ways of life that affect not only the architecture, but also the habitat, work, and, in short, what can be called sustainability. Although sustainability at the human settlement scale has received great attention so far in most of the developing countries, it still remains the most glaring challenge in terms of its demand on resources and expertise. The aim today is to bring modern technologies and knowledge representing design solutions as guidelines like double skin façade, adapting traditional concepts, in tune with such practices to develop solutions that provide us with sustainable buildings that interact and are in harmony with natural climatic conditions. The paper will make an attempt at highlighting sustainability challenges we currently face including its implications for the built environment, in order to propose a sustainability evaluation framework, drawing out transferable lessons learned for future development.

    The home extracorporeal hemodialysis, which aroused a great interest in the past, has not kept its promises due to the complexity and expectations for family involvement in treatment management. In the United States NxStage One portable system was proposed and designed for home use. In this work we describe, starting from the history of home hemodialysis, the method with NxStage system by comparing it with the conventional HD in 5 patients. The dialysis efficiency was similar between the two treatments, even if home hemodialysis showed a reduction in serum urea, creatinine and phosphorus. At the same time phosphate binders use decreased with an increase in serum calcium while hemoglobin increased reducing doses of erythropoietin. The method was successful in the training of the patients and their partners during hospital training and at home. Patients have shown great enthusiasm at the beginning and during the therapy, which is developed around the users personal needs, being able to decide at its own times during 24 hours according to personal needs, in addition to faster recovery after the dialysis. This method certainly improved the patients' wellness and increased their autonomy.

    Full Text Available Previously, we have described the development of the generic mobile phone data gathering tool, EpiCollect, and an associated web application, providing two-way communication between multiple data gatherers and a project database. This software only allows data collection on the phone using a single questionnaire form that is tailored to the needs of the user (including a single GPS point and photo per entry, whereas many applications require a more complex structure, allowing users to link a series of forms in a linear or branching hierarchy, along with the addition of any number of media types accessible from smartphones and/or tablet devices (e.g., GPS, photos, videos, sound clips and barcode scanning. A much enhanced version of EpiCollect has been developed (EpiCollect+. The individual data collection forms in EpiCollect+ provide more design complexity than the single form used in EpiCollect, and the software allows the generation of complex data collection projects through the ability to link many forms together in a linear (or branching hierarchy. Furthermore, EpiCollect+ allows the collection of multiple media types as well as standard text fields, increased data validation and form logic. The entire process of setting up a complex mobile phone data collection project to the specification of a user (project and form definitions can be undertaken at the EpiCollect+ website using a simple ‘drag and drop’ procedure, with visualisation of the data gathered using Google Maps and charts at the project website. EpiCollect+ is suitable for situations where multiple users transmit complex data by mobile phone (or other Android devices to a single project web database and is already being used for a range of field projects, particularly public health projects in sub-Saharan Africa. However, many uses can be envisaged from education, ecology and epidemiology to citizen science.

  5. Urban Revival and College Writing: Writing to Promote Communities

    Full Text Available Service-learning classes, because they emphasize the creation of product that has value outside the confines of the college classroom, offer students an experience in professional formation, a practice that may prove anathema to the ethos of “service.” The desire to counteract this individualistic attitude has led instructors to promulgate an activist agenda within their classrooms, teaching students to critique hierarchical power structures, redress social inequities, or challenge lines of societal exclusion. And yet, such practitioners repeatedly acknowledge the difficulty of this instructional aim and attest to the students’ inability to envision themselves as advocates for societal change. I hold that this objective of transforming students into activists based on the experience of service-learning classes may not be feasible due the economic dynamic of a college classroom, where students pay tuition for their education and engage in work that is assessed and evaluated. Consequently, rather than create service-learning projects around theoretical positions of dissent and critique, I have designed a service-learning class on the topic of urban revitalization that involves students in promotional and collaborative partnerships with non-profit organizations in town. In other words, by tapping into a pragmatic, national movement such as urban renewal, I have aimed to raise the students’ awareness of how they might become agents of change and how their particular skill set of writing could be of service to the community. Drawing upon my experiences with students in a Business and Professional Writing class, I discuss specific readings and writing assignments in this article, chiefly the writing products that were commissioned by different non-profit groups in town. The discussion examines some of the theoretical implications behind reinforcing college students’ awareness of civic commitment while developing their written and rhetorical

    In 1987, Reagan and Gorbachev did agree to abolish an entire class of nuclear weapons - shorter- and intermediate-range missiles - in the INF Treaty. They also created a legacy of dialogue, trust and verification. Significant cuts were subsequently agreed by the two opposing power blocs in everything from military manpower, tanks and warplanes to attack helicopters. There were also verified reductions in strategic nuclear weapons in the START process. Unfortunately, the momentum got lost. In recent years, nuclear threats have become more dangerous and more complex. The number of states known to have nuclear weapons has expanded to nine. Virtually all are extending or modernizing their nuclear weapon arsenals. Others have tried to develop clandestine nuclear programmes. Extremist groups have shown keen interest in acquiring nuclear weapons. Nuclear materials have become more difficult to control. Roughly 27 000 nuclear warheads still remain in the arsenals of these nine countries, 95 percent of which are in the hands of the United States and the Russian Federation. Strategic reliance on these weapons by these countries and their allies undoubtedly motivates others to do the same. And naturally, plans to replenish and modernize these weapons create a pervasive feeling of cynicism among many states - which sense a 'do as I say, not as I do' posture. The rest of the world should actually concentrate on is reaching out to the Middle East by helping to address the dire conditions in the region - chronic and festering conflicts, poverty and social injustice, repression and inept governance. These very conditions are at the root of the pervasive sense of injustice and humiliation that translates into extremism and violence, the drivers for most of the world's major non-proliferation and security concerns. Control of the nuclear fuel cycle is key to curbing proliferation risks. But it must be unambiguously under multinational control, not just managed by the leading nuclear

    The National Institutes of Health National Heart, Lung, and Blood Institute convened a working group in March 2008 to discuss how therapies for heart failure (HF) might be best advanced using clinical trials involving left ventricular assist devices (LVAD). This group opined that the field was ready for a trial to assess the use of long-term ventricular assist device therapy in patients who are less ill than patients currently eligible for destination therapy, which resulted in the Randomized Evaluation of VAD InterVEntion before Inotropic Therapy (REVIVE-IT) pilot study. The specific objective of REVIVE-IT was to compare LVAD therapy with optimal medical management in patients with less advanced HF than current LVAD indications to determine if wider application of permanent LVAD use to less ill patients would be associated with improved survival, quality of life, or functional capacity. REVIVE-IT represented an extraordinary effort to provide data from a randomized clinical trial to inform clinicians, scientists, industry, and regulatory agencies about the efficacy and safety of LVAD therapy in a population with less advanced HF. Despite significant support from the medical community, industry, and governmental agencies, REVIVE-IT failed to accomplish its goal. The reasons for its failure are instructive, and the lessons learned from the REVIVE-IT experience are likely to be relevant to any future study of LVAD therapy in a population with less advanced HF.

    Full Text Available The reflected radiance in topographically complex areas is severely affected by variations in topography; thus, topographic correction is considered a necessary pre-processing step when retrieving biophysical variables from these images. We assessed the performance of five topographic corrections: (i C correction (C, (ii Minnaert, (iii Sun Canopy Sensor (SCS, (iv SCS + C and (v the Processing Scheme for Standardised Surface Reflectance (PSSSR on the Landsat-5 Thematic Mapper (TM reflectance in the context of prediction of Foliage Projective Cover (FPC in hilly landscapes in north-eastern Australia. The performance of topographic corrections on the TM reflectance was assessed by (i visual comparison and (ii statistically comparing TM predicted FPC with ground measured FPC and LiDAR (Light Detection and Ranging-derived FPC estimates. In the majority of cases, the PSSSR method performed best in terms of eliminating topographic effects, providing the best relationship and lowest residual error when comparing ground measured FPC and LiDAR FPC with TM predicted FPC. The Minnaert, C and SCS + C showed the poorest performance. Finally, the use of TM surface reflectance, which includes atmospheric correction and broad Bidirectional Reflectance Distribution Function (BRDF effects, seemed to account for most topographic variation when predicting biophysical variables, such as FPC.

    A bacterial spore was revived, cultured, and identified from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber. Rigorous surface decontamination of the amber and aseptic procedures were used during the recovery of the bacterium. Several lines of evidence indicated that the isolated bacterium was of ancient origin and not an extant contaminant. The characteristic enzymatic, biochemical, and 16S ribosomal DNA profiles indicated that the ancient bacterium is most closely related to extant Bacillus sphaericus.

    In this paper, we extend the intensity-dependent coupling of the interaction of two-level atoms and an electromagnetic field, originated by Sivakumar, to that of Λ-type atoms. In addition, we assume that the interaction occurs in a Kerr medium. In the present model we allow the Λ-type atom to interact with two quantized electromagnetic fields, one of which is initially coherent while the other one is not. We thus report the effect of such coupling and the medium on the collapse-revival's of the photonic mean numbers.

    1984-01-01

    A simple and exact method for evaluation of suspected or overt slip of the femoral capital epiphysis is revived. This procedure gives an estimate of all degrees of abnormality from the early stages to those with gross deformity. In our experience slip of the femoral capital epiphysis is always posterior and in approximately 80% of cases bilateral. Therefore, bot hips should be examined whenever this condition is suspected. The method provides for examination of each hip separately. Strict adherence to the procedure also provides a precise way of assessing the femoral anteversion angle, significant in many orthopedic disorders. For the latter purpose access to a particular nomogram is mandatory. (orig.)

    Twentieth-century China has been caught between a desire to increase its wealth and power in line with other advanced nations, which, by implication, means copying their institutions, practices and values, whilst simultaneously seeking to preserve China's independence and historically formed identity. Over time, Chinese philosophers, writers, artists and politicians have all sought to reconcile these goals and this book shows how this search for a Chinese way penetrated even the most central, least contested area of modernity: science.Reviving Ancient Chinese Mathematics is a study of the life

    2018-06-01

    This paper studies the finite-time hybrid projective synchronization of the drive-response complex networks. In the model, general transmission delays and distributed delays are also considered. By designing the adaptive intermittent controllers, the response network can achieve hybrid projective synchronization with the drive system in finite time. Based on finite-time stability theory and several differential inequalities, some simple finite-time hybrid projective synchronization criteria are derived. Two numerical examples are given to illustrate the effectiveness of the proposed method.

This program is a continuation of the activities of the colloid and complexation group (COCO) in the second phase of the EC-MIRAGE project. A number of different experimental methods are used to determine speciation. The metal ions examined are the trivalent lanthanides, UO 2 2+ , NpO 2 + , Am 3+ , and Cm 3+ . The project is divided into three tasks: Task 1: complexation reactions of actinide ions with well characterized reference and site-specific humic and fulvic acids, Task 2: complexation reactions with major cations in natural groundwaters; Task 3: validation of the complexation data in natural aquatic systems by comparison of calculation with spectroscopic experiment. Five European community laboratories participated in the program: Technische Universitaet Muenchen, Commissariat a l'Energie Atomique Fontenay-Aux-Roses and Saclay, Universitaet Mainz, Katolieke Universiteit Leuven, and Joint Research Centre, Ispra. The evaluated stability constants are similar for all laboratories when the same humic substance complexation model is applied. Humic acid is shown to reduce NpO 2 + to Np 4+ , while no reduction of UO 2 2+ is observed. Temperature effects are seen on the Np humate complex. Competition is observed between NpO 2 + and Ca 2+ , but not between the trivalent lanthanides and Ca 2+ . No influence of humic acid purification on the evaluated stability constants is seen. Using the evaluated constants, calculations are conducted for natural water systems which indicate the trivalent actinide humate complex to be an important species. (orig.)

    Full Text Available On the eve of the 70th anniversary of the Victory in the Great Patriotic War, it is important to analyze the moral factors that contributed to the uplift in the Red Army and the manifestation of mass heroism to defend the Fatherland. During the ordeal, when the fate of the country hung in the balance, the Soviet leadership was forced to revert to the heroic pages of national history and raise the patriotic spirit and the offensive of the armed forces on the front and high productivity at home. Since the 40s of the 19th century in the Russian army it was considered a holy tradition to start the evening roll call from the heroes. During the Great Patriotic War, the tradition was revived. Thus, according to the order of People's Commissar of Defense of the September 8,1943 the hero of the Soviet Union Alexander Matrosov was enlisted in the lists of the 1st company of 254-th Guards Rifle Regiment. Thus, the traditions of the Russian army, revived during the Great Patriotic War, testifies to their eternal spiritual values in matters of moral and patriotic education of servicemen of the Russian armed forces. This historical and pedagogical analysis is of great importance for the spiritual, moral and patriotic education of youth and soldiers of the Russian army at the present stage of development of society.

  20. Collapse and revival of entanglement between qubits coupled to a spin coherent state

    Bahari, Iskandar; Spiller, Timothy P.; Dooley, Shane; Hayes, Anthony; McCrossan, Francis

    We extend the study of the Jayne-Cummings (JC) model involving a pair of identical two-level atoms (or qubits) interacting with a single mode quantized field. We investigate the effects of replacing the radiation field mode with a composite spin, comprising N qubits, or spin-1/2 particles. This model is relevant for physical implementations in superconducting circuit QED, ion trap and molecular systems. For the case of the composite spin prepared in a spin coherent state, we demonstrate the similarities of this set-up to the qubits-field model in terms of the time evolution, attractor states and in particular the collapse and revival of the entanglement between the two qubits. We extend our analysis by taking into account an effect due to qubit imperfections. We consider a difference (or “mismatch”) in the dipole interaction strengths of the two qubits, for both the field mode and composite spin cases. To address decoherence due to this mismatch, we then average over this coupling strength difference with distributions of varying width. We demonstrate in both the field mode and the composite spin scenarios that increasing the width of the “error” distribution increases suppression of the coherent dynamics of the coupled system, including the collapse and revival of the entanglement between the qubits.

    Can memory be retained after cryopreservation? Our research has attempted to answer this long-standing question by using the nematode worm Caenorhabditis elegans, a well-known model organism for biological research that has generated revolutionary findings but has not been tested for memory retention after cryopreservation. Our study's goal was to test C. elegans' memory recall after vitrification and reviving. Using a method of sensory imprinting in the young C. elegans, we establish that learning acquired through olfactory cues shapes the animal's behavior and the learning is retained at the adult stage after vitrification. Our research method included olfactory imprinting with the chemical benzaldehyde (C6H5CHO) for phase-sense olfactory imprinting at the L1 stage, the fast-cooling SafeSpeed method for vitrification at the L2 stage, reviving, and a chemotaxis assay for testing memory retention of learning at the adult stage. Our results in testing memory retention after cryopreservation show that the mechanisms that regulate the odorant imprinting (a form of long-term memory) in C. elegans have not been modified by the process of vitrification or by slow freezing.

    We study the effect of a many-body interaction on inter-band oscillations in a two-band Bose-Hubbard model with an external Stark force. Weak and strong inter-band oscillations are observed, where the latter arise from a resonant coupling of the bands. These oscillations collapse and revive due to a weak two-body interaction between the atoms. Effective models for oscillations in and out of resonance are introduced that provide predictions for the system's behaviour, particularly for the time scales for the collapse and revival of the resonant inter-band oscillations.

  3. Projected [1H,15N]-HMQC-[1H,1H]-NOESY for large molecular systems: application to a 121 kDa protein-DNA complex

    International Nuclear Information System (INIS)

    Galius, Veniamin; Leontiou, Chrysoula; Richmond, Timothy; Wider, Gerhard

    2008-01-01

    We present a projected [ 1 H, 15 N]-HMQC-[ 1 H, 1 H]-NOESY experiment for observation of NOE interactions between amide protons with degenerate 15 N chemical shifts in large molecular systems. The projection is achieved by simultaneous evolution of the multiple quantum coherence of the nitrogen spin and the attached proton spin. In this way NOE signals can be separated from direct-correlation peaks also in spectra with low resolution by fully exploiting both 1 H and 15 N frequency differences, such that sensitivity can be increased by using short maximum evolution times. The sensitivity of the experiment is not dependent on the projection angle for projections up to 45 deg. and no additional pulses or delays are required as compared to the conventional 2D [ 1 H, 15 N]-HMQC-NOESY. The experiment provides two distinct 2D spectra corresponding to the positive and negative angle projections, respectively. With a linear combination of 1D cross-sections from the two projections the unavoidable sensitivity loss in projection spectra can be compensated for each particular NOE interaction. We demonstrate the application of the novel projection experiment for the observation of an NOE interaction between two sequential glycines with degenerate 15 N chemical shifts in a 121.3 kDa complex of the linker H1 histone protein with a 152 bp linear DNA

  4. Main Revival Movements in the Catholic Church Before the Second Vatican Council

    Full Text Available From the middle of the 19th century until convocation of the Second Vatican Council (1962–1965, several spiritual and intellectual revival movements were visible in the Catholic Church. They had one overarching objective – return to the origins (French: ressourcement. The revival of Biblical Studies, as the first of these movements, was implemented mainly at two specialist universities: the School of Practical Biblical Studies (French: École pratique d’études bibliques of Father Marie-Joseph Lagrange OP and at the Pontifical Biblical Institute (Pontificium Institutum Biblicum founded by Pope Saint Pius X. The Movement of Liturgical renewal, on the other hand, began at the Benedictine abbeys in Belgium, France and Germany, and was later popularised by Father Prosper Guéranger OSB, Father Lambert Beauduin OSB and Father Odo Casel OSB. Similarly as in the case of the Biblical revival, the teaching of successive Popes – and of Pius XII in particular – had a significant influence on changes in the Catholic liturgy. In contrast, the Ecumenical Movement was characterised by its bottom-up nature, and its beginnings were associated initially with Protestant missionary circles. An important contribution to this transformative movement were meetings between the Catholic and the Anglican Church, known as the Malines Conversations (French: Conversations des Malines, as well as the Una Sancta ecumenical movement developing robustly in Germany. Finally, the last crucial phenomenon – ain particular from the perspective of genesis of the Second Vatican Council – was the rise of Nouvelle Théologie, a new school of thought in Catholic theology. Its representatives include leading theologians of the 20th century: Father Henri de Lubac SJ, Father Karl Rahner SJ, Father Yves Congar OP, Father Marie-Dominique Chenu OP, as well as Father Joseph Ratzinger (Pope Benedict XVI and Father Hans Küng. It should be emphasised all the above Catholic renewal

    This paper investigates generalized function matrix projective lag synchronization between fractional-order and integer-order complex networks with delayed coupling, non-identical topological structures and different dimensions. Based on Lyapunov stability theory, generalized function matrix projective lag synchronization criteria are derived by using the adaptive control method. In addition, the three-dimensional fractional-order chaotic system and the four-dimensional integer-order hyperchaotic system as the nodes of the drive and the response networks, respectively, are analyzed in detail, and numerical simulation results are presented to illustrate the effectiveness of the theoretical results.

    Full Text Available Abstract: Based upon elite interviews, document analysis and library research, this study analyses the responses of the Indonesian Muslim political elite to the phenomena of the emergence of the alleged communist Partai Rakyat Demokratik (People’s Democratic Party and the flourishing of the Leftist books in Indonesia during 1996-2001 which is one of the most critical historical phases in Indonesian politics that witnessed significant political changes affecting the life of Indonesians in general and Muslims in particular. The adverse responses of most Muslim political elite to the revival of the Left are basically driven by the interweaving of theological, historical and political factors as well as traumatic historical experience. With the passage of time, there have been significant changes, and strained relations between Islamic political groups and the Leftists have thawed but not eliminated.

  10. From antiquity to Olympic revival: sports and Greek national historiography (nineteenth-twentieth centuries).

    Koulouri, Christina

    2010-01-01

    This study investigates the evolution of the historiography of Greek sport from the foundation of the Greek state (1830) until 1982 and its links with Greek national history, which also took shape primarily during the nineteenth century. The gradual 'nationalisation' of sport as an element of Greek national character since antiquity corresponded to changes in perceptions of the national past reflected in historiography. The ancient Olympic Games, Byzantine contests and exercises, the competitions of the klephts and armatoloi (militia soldiers) during the Ottoman rule and the modern revival of the Olympic Games were all successively integrated in a national history of sport confirming national continuity and unity. However this particular genre of national historiography did not gain academic recognition until recently. The authors of histories of physical exercise and sport were amateurs or physical education instructors and could not ensure to their work the authority of a separate discipline.

    Full Text Available The article reveals the urgency of the problems of revitalization and preservation of historical memory in the national and regional contexts at different stages of the past and in the present. It is shown that the historical memory of our region, like most other regions of the country, reflected the five main periods, in particular Russian, Cossack, Imperial, Soviet, modern Ukrainian. Noted that the heterogeneity of the historical memory caused rather substantial differences in the individual and collective media, despite the fact that the inhabitants of the region were a territorial community which were distinguishable features: social, ethnic, political, religious, linguistic, cultural, professional, age, sex, etc. are Focused on those key features, which caused quite stable signs of historical memory inherent in our region in different historical periods. Value is defined revival and preservation of historical memory in the development of modern national identity, the modern historical consciousness and thinking.

    This colloquium took place less than 1 year after the decision of the US of revival of their nuclear program. Thus the international context has changed, even if nuclear contestation remains as strong as in the past. Among governments, some positions preach the banishment of nuclear energy while others consider the nuclear option as the only solution to meet the growing up energy demand and the future environmental and economical stakes. This report makes a synthesis of the different talks given by the participants during the 3 round tables of the colloquium on the future of nuclear energy: the ecological stake, the democratic stake, and the energy policy stake. Four talks of French government representatives open and conclude the debates of the different round tables. (J.S.)

  14. Reviving and Refining Psychodynamic Interpretation of the Wechsler Intelligence Tests: The Verbal Comprehension Subtests.

    Bram, Anthony D

    2017-01-01

    The Wechsler intelligence tests (currently Wechsler, 2008 , 2014) have traditionally been part of the multimethod test battery favored by psychodynamically oriented assessors. In this tradition, assessors have used Wechsler data to make inferences about personality that transcend cognition. Recent trends in clinical psychology, however, have deemphasized this psychodynamic way of working. In this article, I make a conceptual and clinical case for reviving and refining a psychodynamic approach to inference making about personality using the Wechsler Verbal Comprehension subtests. Specifically, I (a) describe the psychological and environmental conditions sampled by the Wechsler tests, (b) discuss the Wechsler tests conceptually in terms of assessing vulnerability to breakdowns in adaptive defensive functioning, (c) review a general framework for inference making, and (d) offer considerations for and illustrate pragmatic application of the Verbal Comprehension subtests data to make inferences that help answer referral questions and have important treatment implications.

    By soft fixing cadavers using the Thiel embalming method, our cadavers now exhibit a greater degree of flexibility and color retention compared to that of traditional formalin-fixed cadavers. The aim of this experiment was to discover whether Thiel embalming fluid could be used to revive and soften the muscles of formalin-fixed prosected specimens. Earlier this year, two severely dehydrated formalin-fixed forearm and hand specimens were fully submerged in a tank containing Thiel embalming fluid. After a period of six months the specimens were removed from the tank and noticeable changes were observed in flexibility, quality of the tissue, and color of the specimens. © 2014 Wiley Periodicals, Inc.

  16. Reviving Vibration Energy Harvesting and Self-Powered Sensing by a Triboelectric Nanogenerator

    KAUST Repository

    Chen, Jun

    2017-10-10

    Vibration energy harvesting and sensing is a traditional and growing research field in which various working mechanisms and designs have been developed for an improved performance. Relying on a coupling effect of contact electrification and electrostatic induction, in the past 5 years, triboelectric nanogenerator (TENG) has been applied as a fundamentally new technology to revive the field of vibration energy harvesting and self-powered sensing, especially for low-frequency vibrations such as human motion, automobile, machine, and bridge vibrations. The demonstrated instantaneous energy conversion efficiency of ∼70% and a total efficiency up to 85% distinguished TENG from traditional techniques. In this article, both TENG-enabled vibration energy harvesting and self-powered active sensing are comprehensively reviewed. Moving toward future development, problems pressing for solutions and onward research directions are also posed to deliver a coherent picture.

  17. Reviving Complementarity: John Wheeler's efforts to apply complementarity toward a quantum description of gravitation

    Science.gov (United States)

    Halpern, Paul

    2017-01-01

    In 1978, John Wheeler proposed the delayed-choice thought experiment as a generalization of the classic double slit experiment intended to help elucidate the nature of decision making in quantum measurement. In particular, he wished to illustrate how a decision made after a quantum system was prepared might retrospectively affect the outcome. He extended his methods to the universe itself, raising the question of whether the universe is a ``self-excited circuit'' in which scientific measurements in the present affect the quantum dynamics in the past. In this talk we'll show how Wheeler's approach revived the notion of Bohr's complementarity, which had by then faded from the prevailing discourse of quantum measurement theory. Wheeler's advocacy reflected, in part, his wish to eliminate the divide in quantum theory between measurer and what was being measured, bringing greater consistency to the ideas of Bohr, a mentor whom he deeply respected.

    A case study was conducted of the formation of a diabetes initiative in a largely African American urban community. The study focused on how confluent the original project model was with actual formation, what benefits were produced, what areas of needed improvement surfaced, and how different stakeholder groups characterized one another's involvement. The project produced several benefits but also experienced needed improvements in its formation, which suffered from a lack of communication, cooperation, and coordination; unclear goals and personnel roles; and early delays. Lessons include treating project formation as an important developmental stage and reducing bureaucratic management approaches not suited for community partnerships.

    2016-04-01

    The aim of the European REVIVE survey was to achieve a better understanding of vulvovaginal atrophy (VVA), a chronic and progressive condition after menopause. We investigated perceptions, experiences and needs in terms of sexual and vaginal health in a sample of European postmenopausal women. An online internet based survey was conducted in Italy, Germany, Spain and the UK with a total surveyed sample of 3768 postmenopausal women (age: 45-75 years). The most common VVA symptom was vaginal dryness (70%). VVA has a significant impact on the ability to be intimate (62%), to enjoy sexual intercourse (72%) and to feel sexual spontaneity (66%). Postmenopausal women with VVA are sexually active (51%), but their sexual drive is reduced. Health-care professionals (HCPs) have discussed VVA with postmenopausal women (62%), but they initiated the conversation only in 10% of the cases. The most common treatments for VVA are over-the-counter, non-hormonal, local vaginal products. Thirty-two per cent of postmenopausal women were naïve to any kind of treatment, whereas discussion with the HCP was relevant to be on current treatment (60% of postmenopausal women that discussed VVA with a HCP vs. 23% who did not). The top reasons for poor compliance with vaginal treatments were: not bothersome enough symptoms (18%); vaginal changes not therapeutically reversed (18%); relief from VVA symptoms (17%). Approximately 45% were satisfied with treatment. The most frequent disliked aspects of treatment were the route of administration or the messiness. The fear of hormones was common in postmenopausal women using vaginal prescription products. The European REVIVE survey confirmed that VVA symptoms are frequent in postmenopausal women and demonstrates a significant impact on quality of life and sexual life. However, the condition is still under-diagnosed and under-treated, with a high rate of dissatisfaction for actual available treatments in the four European countries surveyed. The

    2015-12-01

    We examine the conditions for the revival of the stalled accretion shock in core-collapse supernovae, in the context of the neutrino heating mechanism. We combine one-dimensional simulations of the shock revival process with a derivation of a quasi-stationary approximation, which is both accurate and efficient in predicting the flow. In particular, this approach is used to explore how the evolution of the accretion shock depends on the shock radius, RS, and velocity, VS (in addition to other global properties of the system). We do so through a phase-space analysis of the shock acceleration, aS, in the {R}S{--}{V}S plane, shown to provide quantitative insights into the initiation and nature of runaway expansion. In the particular case of an initially stationary ({V}S=0, {a}S=0) profile, the prospects for an explosion can be assessed by the initial signs of the partial derivatives of the shock acceleration, in analogy to a linear damped/anti-damped oscillator. If \\partial {a}S/\\partial {R}S\\lt 0 and \\partial {a}S/\\partial {V}S\\gt 0, runaway will likely occur after several oscillations, while if \\partial {a}S/\\partial {R}S\\gt 0, runaway expansion will commence in a non-oscillatory fashion. These two modes of runaway correspond to low and high mass accretion rates, respectively. We also use the quasi-stationary approximation to assess the advection-to-heating timescale ratio in the gain region, often used as an explosion proxy. Indeed, this ratio does tend to ∼1 in conjunction with runaway conditions, but neither this unit value nor the specific choice of the gain region as a point of reference appear to be unique in this regard.

    An exploratory study was conducted that investigated the influence of technical uncertainty and project complexity on information use by U.S. industry-affiliated aerospace engineers and scientists. The study utilized survey research in the form of a self-administered mail questionnaire. U.S. aerospace engineers and scientists on the Society of Automotive Engineers (SAE) mailing list served as the study population. The adjusted response rate was 67 percent. The survey instrument is appendix C to this report. Statistically significant relationships were found to exist between technical uncertainty, project complexity, and information use. Statistically significant relationships were found to exist between technical uncertainty, project complexity, and the use of federally funded aerospace R&D. The results of this investigation are relevant to researchers investigating information-seeking behavior of aerospace engineers. They are also relevant to R&D managers and policy planners concerned with transferring the results of federally funded aerospace R&D to the U.S. aerospace industry.

  2. Second-order Monte Carlo wave-function approach to the relaxation effects on ringing revivals in a molecular system interacting with a strongly squeezed coherent field

    2004-01-01

    We investigate the relaxation effects on the quantum dynamics in a two-state molecular system interacting with a single-mode strongly amplitude-squeezed coherent field using the second-order Monte Carlo wave-function method. The molecular population inversion (collapse-revival behavior of Rabi oscillations) is known to show the echoes after each revival, which are referred to as ringing revivals, in the case of strongly squeezed coherent fields with oscillatory photon-number distributions due to the phase-space interference effect. Two types of relaxation effects, i.e., cavity relaxation (the dissipation of an internal single mode to outer mode) and molecular coherent (phase) relaxation caused by nuclear vibrations on ringing revivals are investigated from the viewpoint of the quantum-phase dynamics using the quasiprobability (Q function) distribution of a single-mode field and the off-diagonal molecular density matrix ρ elec1,2 (t). It turns out that the molecular phase relaxation attenuates both the entire revival-collapse behavior and the increase in ρ elec1,2 (t) during the quiescent region, whereas a very slight cavity relaxation particularly suppresses the echoes in ringing revivals more significantly than the first revival but hardly changes a primary variation in envelope of ρ elec1,2 (t) in the nonrelaxation case

  5. Corticofugal projections induce long-lasting effects on somatosensory responses in the trigeminal complex of the rat

    2014-05-01

    Full Text Available The sensory information flow at subcortical relay stations is controlled by the action of topographic connections from the neocortex. To determinate the functional properties of the somatosensory corticofugal projections to the principal (Pr5 and caudal spinal (Sp5C trigeminal nuclei, we performed unitary recordings in anesthetized rats. To examine the effect of these cortical projections we used tactile stimulation of the whisker and electrical stimulation of somatosensory cortices. Corticofugal anatomical projections to Pr5 and Sp5C nuclei were detected by using retrograde fluorescent tracers. Neurons projecting exclusively to Pr5 were located in the cingulate cortex while neurons projecting to both Sp5C and Pr5 nuclei were located in the somatosensory and insular cortices (>75% of neurons. Physiological results indicated that primary somatosensory cortex produced a short-lasting facilitating or inhibiting effects (< 5 minutes of tactile responses in Pr5 nucleus through activation of NMDA glutamatergic or GABAA receptors since effects were blocked by iontophoretically application of APV and bicuculline, respectively. In contrast, stimulation of secondary somatosensory cortex did not affect most of the Pr5 neurons; however both cortices inhibited the nociceptive responses in the Sp5C nucleus through activation of glycinergic or GABAA receptors because effects were blocked by iontophoretically application of strychnine and bicuculline, respectively. These and anatomical results demonstrated that the somatosensory cortices projects to Pr5 nucleus to modulate tactile responses by excitatory and inhibitory actions, while projections to the Sp5C nucleus control nociceptive sensory transmission by only inhibitory effects. Thus, somatosensory cortices may modulate innocuous and noxious inputs simultaneously, contributing to the perception of specifically tactile or painful sensations.

  6. Prospects for a genuine revival of primary health care--through the visible hand of social justice rather than the invisible hand of the market: Part II.

    2010-01-01

    This second part of a two-part article explores the prospects for genuine revival of primary health care (PHC) as announced by the WHO in 2008, with reference, briefly, to Global Health Watch 2, published by the People's Health Movement, Medact, and Equity Gauge Alliance, and, in more depth, to the positions of social and people's movements most closely aligned with the original values and principles of Alma-Ata and the structural foundations of the PHC project. The author argues that the social justice struggle for health cannot be limited to curbing capitalism's excesses. The multiple crises of today--in energy, water, food, the environment, finance, science, information, and democracy--must be recognized as capitalist crises and addressed as such. Particular attention is given to ideology, including the distortion of human nature and society under neoliberal capitalism, and to moral foundations of Health for All. Not only must the invisible hand of the market be replaced by the visible hand of social justice, but the single ideology proclaiming the "end of history" and, by implication, the end of politics and political struggle must be exposed and rejected as neoliberal, totalitarian propaganda. In line with the spirit and intention of the U.N. Charter, PHC remains a political project for a fair and safe world in which Health for All is both possible and necessary.

    Construction project features (CPFs) are organisational, physical and operational attributes that characterise construction projects. Although previous studies have examined the accident causal influence of CPFs, the multi-causal attribute of this causal phenomenon still remain elusive and thus requires further investigation. Aiming to shed light on this facet of the accident causal phenomenon of CPFs, this study examines relevant literature and crystallises the attained insight of the multi-causal attribute by a graphical model which is subsequently operationalised by a derived mathematical risk expression that offers a systematic approach for evaluating the potential of CPFs to cause harm and consequently their health and safety (H&S) risk implications. The graphical model and the risk expression put forth by the study thus advance current understanding of the accident causal phenomenon of CPFs and they present an opportunity for project participants to manage the H&S risk associated with CPFs from the early stages of project procurement.

    Full Text Available Background: Uttar Pradesh (UP is the most populous state in India. The maternal mortality ratio, infant mortality rate, and fertility rates are all higher than the national average. Sixty percent of UP inhabitants live in rural communities. The reasons behind the poor state of health and services in many areas of UP are inadequate knowledge and availability in communities of healthy behaviors, and information on available government health services. Methods: World Vision, Inc. implemented a three-and-half year mobilizing plan for maternal and neonatal health through a birth spacing and advocacy project (MOMENT, partnering with local organizations in rural Hardoi and urban slums of Lucknow districts in UP. World Vision used print, audio, visual media, and house-to-house contacts to educate communities on timing and spacing of pregnancies; and the benefits of seeking and using maternal and child health services (MCH including immunization and family planning (FP.This paper focuses on World Vision’s social accountability strategy – Citizen Voice and Action (CVA and interface meetings – used in Hardoi that helped educate and empower Village Health Sanitation and Nutrition Committees (VHSNCs and village leaders to access government untied funds to improve community social and health services. Results: Forty VHSNCs were revived in 24 months. Nine local leaders accessed government untied funds. In addition, increased knowledge of the benefits of timing and spacing of pregnancies, maternal child health, family planning services, and access to community entitlements led the community to embrace and contribute their time to rebuild and re-open 17 non-functional Auxiliary Nurse Midwife (ANM sub-centers. Seventeen ANMs received refresher training to provide quality care. Sub-center data showed that 1,121 and 3,156 women opted for intra-uterine contraceptive device and oral pills, respectively, and 29,316 condoms were distributed. Conclusion: In Hardoi

    The detection of irradiated constituents in processed food with a complex lipid matrix can be adversely affected by two conditions. The small amounts of radiation-induced hydrocarbons are diluted by the fat matrix of the food, or there are substances accompanying the lipids in the matrix and thus make the analysis more difficult. In those cases, sample preparation alone by means of Florisil SPE (solid-phase extraction) is not enough and requires additional, subsequent SPE argentation chromatography of the Florisil eluate, as this latter analytical method permits reliable detection down to very small amounts of irradiated, fat-containing constituents even in a complex lipid matrix. SPE-Florisil/argentation chromatography detects and selects radiation-induced hydrocarbons in a complex lipid matrix, so that detection of irradiation at even very low doses down to 0.025 kGy is possible. The method described is highly sensitive, inexpensive, and easy to apply. It efficiently substitutes such complex preparation or measuring methods as SFE-GC/MS or LC-GC/MS. This highly sensitive testing method for detection of food irradiation can be carried out in almost any analytical laboratory. (orig./CB) [de

    Diller, Kyle I; Bayden, Alexander S; Audie, Joseph; Diller, David J

    2018-01-01

    There is growing interest in peptide-based drug design and discovery. Due to their relatively large size, polymeric nature, and chemical complexity, the design of peptide-based drugs presents an interesting "big data" challenge. Here, we describe an interactive computational environment, PeptideNavigator, for naturally exploring the tremendous amount of information generated during a peptide drug design project. The purpose of PeptideNavigator is the presentation of large and complex experimental and computational data sets, particularly 3D data, so as to enable multidisciplinary scientists to make optimal decisions during a peptide drug discovery project. PeptideNavigator provides users with numerous viewing options, such as scatter plots, sequence views, and sequence frequency diagrams. These views allow for the collective visualization and exploration of many peptides and their properties, ultimately enabling the user to focus on a small number of peptides of interest. To drill down into the details of individual peptides, PeptideNavigator provides users with a Ramachandran plot viewer and a fully featured 3D visualization tool. Each view is linked, allowing the user to seamlessly navigate from collective views of large peptide data sets to the details of individual peptides with promising property profiles. Two case studies, based on MHC-1A activating peptides and MDM2 scaffold design, are presented to demonstrate the utility of PeptideNavigator in the context of disparate peptide-design projects.

    2015-01-01

    Full Text Available The Faculty of Law in Belgrade was a reputable institution of higher education between the two world wars. The occupation of the country disrupted its work and the building was seized by the occupation troops. This paper presents the strenuous exertions and difficulties following the revival efforts of the Faculty of Law in Belgrade after the liberation. The preparations designed to revive the work of the Faculty began immediately after the liberation of the city in October 1944. Furthermore, numerous problems had to be solved such as accommodation, teaching staff, lack of textbooks, etc. The great self-sacrifice of the teaching staff and non-teaching personnel created conditions that enabled the Faculty of Law in Belgrade to re-open the doors to the students by the beginning of November 1945.

    To determine the efficacy of Omnilux Revive facial treatment in skin rejuvenation, twenty-three volunteers received randomised 20 min treatments three times a week for three weeks to one half of their face, with the untreated side acting as control. Regular assessments were carried out, focusing on parameters of subject satisfaction, photographic assessments, skin elasticity (Cutometer) and skin hydration (Corneometer CM825). Ninety-one percent of the volunteers reported visible changes to their skin. Blinded photographic evaluation reported a clinical response in 59% of the subjects. Objective analysis failed to show statistically significant changes in skin hydration or elasticity. The Omnilux Revive LED lamp is a safe alternative non-ablative skin rejuvenation treatment.

    The above complex is surveyed for the promotion of CDM (clean development mechanism) which is a flexibility measure in the Kyoto Protocol. The 4 existing 7.5-ton electric furnaces are antiquated and high in electric power consumption rate, and cause much dust pollution. A project is worked out, under which the furnace volume will be reduced to save energy and to realize environmental friendliness. The project aims to save power, reduce greenhouse gas emission, and settle environmental problems such as dust generation. The refurbishment will reduce greenhouse gas by 27,211 tons a year in the case of a 100,000 tons/year-capable plant. This means 663 tons of CO2 per 100-million yen of invested capital.

    Neuronal activity in medial prefrontal cortex (mPFC) is critical for the formation of trace fear memory, yet the cellular mechanisms underlying these memories remain unclear. One possibility involves the modulation of intrinsic excitability within mPFC neurons that project to the basolateral complex of amygdala (BLA). The current study used a combination of retrograde labeling and in vitro whole-cell patch-clamp recordings to examine the effect of trace fear conditioning on the intrinsic excitability of layer 5 mPFC-BLA projection neurons in adult rats. Trace fear conditioning significantly enhanced the intrinsic excitability of regular spiking infralimbic (IL) projection neurons, as evidenced by an increase in the number of action potentials after current injection. These changes were also associated with a reduction in spike threshold and an increase in h current. In contrast, trace fear conditioning reduced the excitability of regular spiking prelimbic (PL) projection neurons, through a learning-related decrease of input resistance. Interestingly, the amount of conditioned freezing was (1) positively correlated with excitability of IL-BLA projection neurons after conditioning and (2) negatively correlated with excitability of PL-BLA projection neurons after extinction. Trace fear conditioning also significantly enhanced the excitability of burst spiking PL-BLA projection neurons. In both regions, conditioning-induced plasticity was learning specific (observed in conditioned but not in pseudoconditioned rats), flexible (reversed by extinction), and transient (lasted extinction of trace fear conditioning. Significance statement: Frontal lobe-related function is vital for a variety of important behaviors, some of which decline during aging. This study involves a novel combination of electrophysiological recordings from fluorescently labeled mPFC-to-amygdala projection neurons in rats with acquisition and extinction of trace fear conditioning to determine how

  2. A model for integrating clinical care and basic science research, and pitfalls of performing complex research projects for addressing a clinical challenge.

    2010-07-01

    The collaboration of clinicians with basic science researchers is crucial for addressing clinically relevant research questions. In order to initiate such mutually beneficial relationships, we propose a model where early career clinicians spend a designated time embedded in established basic science research groups, in order to pursue a postgraduate qualification. During this time, clinicians become integral members of the research team, fostering long term relationships and opening up opportunities for continuing collaboration. However, for these collaborations to be successful there are pitfalls to be avoided. Limited time and funding can lead to attempts to answer clinical challenges with highly complex research projects characterised by a large number of "clinical" factors being introduced in the hope that the research outcomes will be more clinically relevant. As a result, the complexity of such studies and variability of its outcomes may lead to difficulties in drawing scientifically justified and clinically useful conclusions. Consequently, we stress that it is the basic science researcher and the clinician's obligation to be mindful of the limitations and challenges of such multi-factorial research projects. A systematic step-by-step approach to address clinical research questions with limited, but highly targeted and well defined research projects provides the solid foundation which may lead to the development of a longer term research program for addressing more challenging clinical problems. Ultimately, we believe that it is such models, encouraging the vital collaboration between clinicians and researchers for the work on targeted, well defined research projects, which will result in answers to the important clinical challenges of today.

    Revival of dormant tumor cells may be an important tumor metastasis mechanism. We hypothesized that aurora kinase A (AURKA), a cell cycle control kinase, promotes the transition of laryngeal squamous cell carcinoma (LSCC) cells from G0 phase to active division. We therefore investigated whether AURKA could revive dormant tumor cells to promote metastasis. Western blotting revealed that AURKA expression was persistently low in dormant laryngeal cancer Hep2 (D-Hep2) cells and high in non-dormant (T-Hep2) cells. Decreasing AURKA expression in T-Hep2 cells induced dormancy and reduced FAK/PI3K/Akt pathway activity. Increasing AURKA expression in D-Hep2 cells increased FAK/PI3K/Akt pathway activity and enhanced cellular proliferation, migration, invasion and metastasis. In addition, FAK/PI3K/Akt pathway inhibition caused dormancy-like behavior and reduced cellular mobility, migration and invasion. We conclude that AURKA may revive dormant tumor cells via FAK/PI3K/Akt pathway activation, thereby promoting migration and invasion in laryngeal cancer. AURKA/FAK/PI3K/Akt inhibitors may thus represent potential targets for clinical LSCC treatment. PMID:27356739

    A 160-ps near-Gaussian, linearly polarized laser pulse is used to align iodine (I2) molecules embedded in helium nanodroplets. The rise time of the laser pulse is sufficiently long and smooth that the alignment, characterized by , behaves adiabatically during the pulse turnon. However, after the laser pulse has turned off stays above 0.50 and a recurrence structure occurs ˜650 ps later. Measurements on isolated (I2) molecules with identical laser pulses are used to identify, through analysis of the observed half- and full-rotational revivals, that the nonadiabatic postpulse alignment dynamics results from a mild truncation of the trailing edge of the laser pulse. This truncation establishes a well-defined starting time for coherent rotation, which leads to the revival structures observed both for isolated molecules and molecules in He droplets. In the latter case the time-dependent trace recorded here is compared to that obtained previously for a 450-fs alignment pulse. It is found that the observed revivals are very similar.

    Full Text Available Theatrical art had a significant influence on the formation of social and cultural space of the city at all times. Currently Khabarovsk is one of the theatrical art centres in the Russian Far East. In this regional center theaters of different genres and periods exist. To study the Khabarovsk puppet theater is relevant because of growing interest of viewers of different ages to its activity, as well as the increasing role of the theater in the cultural and social development of the Far Eastern region. The puppet theater was created and later revived in the period of social modernization of the 1920s and 1990s. The paper attempts to identify the causes of the popularization of puppet theaters in certain historical periods. The peculiarities of a puppet genre can be explained by the Russian Far East situation at that time that created the appearance of the city puppeteers in the theatrical space whose work accumulated all the best traditions of Russian and the world puppet genre. Archive documentation analysis allowed creating a holistic view of the puppet theater major directions in the period of radical transformation of the 1990s.

    Additive manufacturing techniques are getting more and more established as reliable methods for producing porous metal implants thanks to the almost full geometrical and mechanical control of the designed porous biomaterial. Today, Ti6Al4V ELI is still the most widely used material for porous implants, and none or little interest goes to pure titanium for use in orthopedic or load-bearing implants. Given the special mechanical behavior of cellular structures and the material properties inherent to the additive manufacturing of metals, the aim of this study is to investigate the properties of selective laser melted pure unalloyed titanium porous structures. Therefore, the static and dynamic compressive properties of pure titanium structures are determined and compared to previously reported results for identical structures made from Ti6Al4V ELI and tantalum. The results show that porous Ti6Al4V ELI still remains the strongest material for statically loaded applications, whereas pure titanium has a mechanical behavior similar to tantalum and is the material of choice for cyclically loaded porous implants. These findings are considered to be important for future implant developments since it announces a potential revival of the use of pure titanium for additively manufactured porous implants.

    Full Text Available Islam presents a comprehensive system of life based on divine guidance. Its dynamism is due its general principles through which solutions for any conceivable situation could be sought. This is in line with the signification of the Quranic verse: “We have not neglected in the record a thing . . .” This necessitates the adoption of an adequate methodology for the derivation of rulings from revealed source. A strict literal approach in understanding of the revealed text would not facilitate solutions for new issues due to the limitation of the text. Thus, maslahah, as a method of interpretation of revealed guidance can play a crucial role in providing solutions for new issues of legal and civilizational nature. Therefore, this article attempts to examine the instrumental role of maslahah in revitalization of Islamic thought. It also highlights the necessity for reviving ijtihad through which stagnation from intellectual spheres of Muslim world could be removed. Maslahah in this context provides an effective instrument for the purpose, hence, can play significant role in restoring originality and dynamism to Islamic thought.

    Wood-pastures are associated with high cultural and biodiversity values in Europe. However, due to their relatively low productivity, large areas of wood-pastures have been lost over the last century. In some areas, incentive schemes have been developed to revive wood-pastures. We investigated the effects of one such scheme in western Estonia. We compared the structure of grazed wood-pastures (old and restored) to those of abandoned wood-pastures and ungrazed forest stands to explore the effects of management, and conducted interviews with 24 farmers to investigate their motivations to carry out the management. We found a positive influence of active management on the semi-open structure of wood-pastures. Financial support was vital for management, but personal values related to tradition also played an important role. The interviewees differed widely in their range of motivations, suggesting that other strategies in addition to financial incentives would further improve the management of wood-pastures in the region.

    2010-11-01

    Ventricular assist devices (VADs) are used to bridge heart failure patients to transplantation, to allow their own hearts to recover, or as permanent ("destination") therapy. To date, the use of VADs has been limited to late-stage heart failure patients because of the associated device risks. In 2008, a National Heart, Lung, and Blood Institute (NHLBI) working group met to evaluate the treatment of heart failure using VADs and to advise the institute on how therapy for heart failure may be best advanced by clinical trials involving the devices. Recognizing the improvements in VAD technology and in patient care and selection over the past decade, the working group recommended that a trial be performed to assess the use of chronic VAD therapy in patients who are less ill than those currently eligible for destination therapy. The hypothesis proposed for the trial is that VAD therapy may improve both survival and quality of life in moderately advanced heart failure patients who are neither inotrope-dependent nor exercise-intolerant and have not yet developed serious consequences such as malnourishment, end-organ damage, and immobility. Based on the group's recommendations, NHLBI issued an RFP in 2009 for the REVIVE-IT Pilot Trail, which will serve to test the hypothesis and inform the pivotal trial. Published by Elsevier Inc.

    The Pan-Asian REVIVE survey aimed to examine women's experiences with genitourinary syndrome of menopause (GSM) and their interactions with health-care professionals (HCPs). Self-completed surveys were administered face-to-face to 5992 women (aged 45-75 years) in Indonesia, Malaysia, Singapore, Taiwan, and Thailand. Of 638 postmenopausal women with GSM symptoms, only 35% were aware of the GSM condition, most of whom first heard of GSM through their physician (32%). The most common symptoms were vaginal dryness (57%) and irritation (43%). GSM had the greatest impact on sexual enjoyment (65%) and intimacy (61%). Only 25% had discussed their GSM symptoms with a HCP, and such discussions were mostly patient-initiated (64%) rather than HCP-initiated (24%). Only 21% had been clinically diagnosed with GSM and only 24% had ever used treatment for their symptoms. Three-quarters of those who had used treatment for GSM had discussed their symptoms with a HCP compared to only 9% of those who were treatment-naïve. GSM is underdiagnosed and undertreated in Asia. As discussion of GSM with HCPs appears to be a factor influencing women's awareness and treatment status, a more active role by HCPs to facilitate early discussions on GSM and its treatment options is needed.

    Drawing on previous empirical research, we provide an exemplary narrative to illustrate how patients have experienced hospital care organized according to evidence-based fast-track programmes. The aim of this paper was to analyse and discuss if and how it is possible to include patients' individual perspectives in an evidence-based practice as seen from the point of view of nursing theory. The paper highlights two conflicting courses of development. One is a course of standardization founded on evidence-based recommendations, which specify a set of rules that the patient must follow rigorously. The other is a course of democratization based on patients' involvement in care. Referring to the analysis of the narrative, we argue that, in the current implementation of evidence-based practice, the proposed involvement of patients resembles empty rhetoric. We argue that the principles and values from evidence-based medicine are being lost in the transformation into the current evidence-based hospital culture which potentially leads to a McDonaldization of nursing practice reflected as 'one best way'. We argue for reviving ethics of care perspectives in today's evidence practice as the fundamental values of nursing may potentially bridge conflicts between evidence-based practice and the ideals of patient participation thus preventing a practice of 'McNursing'. © 2017 John Wiley & Sons Ltd.

    The military is undergoing a significant transformation as it modernizes for the information age and adapts to address an emerging asymmetric threat beyond traditional cold war era adversaries. Techniques such as traditional large-scale, joint services war gaming analysis are no longer adequate to support program evaluation activities and mission planning analysis at the enterprise level because the operating environment is evolving too quickly. New analytical capabilities are necessary to address modernization of the Department of Defense (DoD) enterprise. This presents significant opportunity to Sandia in supporting the nation at this transformational enterprise scale. Although Sandia has significant experience with engineering system of systems (SoS) and Complex Adaptive System of Systems (CASoS), significant fundamental research is required to develop modeling, simulation and analysis capabilities at the enterprise scale. This report documents an enterprise modeling framework which will enable senior level decision makers to better understand their enterprise and required future investments.

    There is a paucity of data on how to deliver complex interventions that seek to reduce the treatment gap for mental disorders, particularly in sub-Saharan Africa. The need for well-documented protocols which clearly describe the development and the scale-up of programs and interventions is necessary if such interventions are to be replicated elsewhere. This article describes the use of a theory of change (ToC) model to develop a brief psychological intervention for common mental disorders and its' evaluation through a cluster randomized controlled trial in Zimbabwe. A total of eight ToC workshops were held with a range of stakeholders over a 6-month period with a focus on four key components of the program: formative work, piloting, evaluation and scale-up. A ToC map was developed as part of the process with defined causal pathways leading to the desired impact. Interventions, indicators, assumptions and rationale for each point along the causal pathway were considered. Political buy-in from stakeholders together with key resources, which included human, facility/infrastructure, communication and supervision were identified as critical needs using the ToC approach. Ten (10) key interventions with specific indicators, assumptions and rationale formed part of the final ToC map, which graphically illustrated the causal pathway leading to the development of a psychological intervention and the successful implementation of a cluster randomized controlled trial. ToC workshops can enhance stakeholder engagement through an iterative process leading to a shared vision that can improve outcomes of complex mental health interventions particularly where scaling up of the intervention is desired.

    The SAFE (Swarm for Earthquake study) project (funded by European Space Agency in the framework "STSE Swarm+Innovation", 2014-2016) aimed at applying the new approach of geosystemics to the analysis of Swarm satellite (ESA) electromagnetic data for investigating the preparatory phase of earthquakes. We present in this talk the case study of the most recent seismic sequence in Italy. First a M6 earthquake on 24 August 2016 and then a M6.5 earthquake on 30 October 2016 shocked almost in the same region of Central Italy causing about 300 deaths in total (mostly on 24 August), with a revival of other significant seismicity on January 2017. Analysing both geophysical and climatological satellite and ground data preceding the major earthquakes of the sequence we present results that confirm a complex solid earth-atmosphere coupling in the preparation phase of the whole sequence.

    REVIVE SE (REVIVE) is a closed-ended, self-expanding stent retriever used in the RIVER JAPAN study. We present our early experience with REVIVE for revascularization of acute ischemic stroke (AIS) in patients who have failed or are ineligible for intravenous recombinant tissue plasminogen activator treatment. This prospective, single-arm, non-randomized, multicenter registry study followed up patients undergoing mechanical thrombectomy with REVIVE for 90 days. The primary endpoint was a post-procedure Thrombolysis in Cerebral Infarction (TICI) score ≥2a. Secondary endpoints were clot migration/embolization; recanalization without symptomatic intracranial hemorrhage (ICH) at 24 h; symptomatic ICH; good neurological outcome (modified Rankin Scale score ≤2 National Institute of Health Stroke Scale (NIHSS) score decrease ≥10) at day 90; device- or procedure-related serious adverse events (SAEs) and mortality at day 90. To confirm non-inferiority of REVIVE, results were compared with historical data of the Merci Retriever. About 49 patients were enrolled (median age 73 years; males 46.9%; middle cerebral artery (MCA) occlusion 83.7%; median NIHSS score 17). A post-procedure TICI score ≥2a was observed in 73.5% (36/49, 95% confidence interval [CI] 58.9-85.1) of patients. No post-procedural clot migration/embolization events occurred. Successful recanalization without symptomatic ICH was observed in 62.5% (30/48, 95% CI 47.4-76.0). The good neurological outcome was achieved in 66.7% (32/48) patients. Symptomatic ICH and device- or procedure-related SAEs were reported in 6.3% and 12.2% of patients, respectively. Two deaths were reported. REVIVE demonstrated equivalent efficacy and safety as the Merci Retriever. Results suggest that REVIVE is effective and safe in recanalizing occluded intracranial arteries in AIS.

    Additive manufacturing techniques are getting more and more established as reliable methods for producing porous metal implants thanks to the almost full geometrical and mechanical control of the designed porous biomaterial. Today, Ti6Al4V ELI is still the most widely used material for porous implants, and none or little interest goes to pure titanium for use in orthopedic or load-bearing implants. Given the special mechanical behavior of cellular structures and the material properties inherent to the additive manufacturing of metals, the aim of this study is to investigate the properties of selective laser melted pure unalloyed titanium porous structures. Therefore, the static and dynamic compressive properties of pure titanium structures are determined and compared to previously reported results for identical structures made from Ti6Al4V ELI and tantalum. The results show that porous Ti6Al4V ELI still remains the strongest material for statically loaded applications, whereas pure titanium has a mechanical behavior similar to tantalum and is the material of choice for cyclically loaded porous implants. These findings are considered to be important for future implant developments since it announces a potential revival of the use of pure titanium for additively manufactured porous implants. - Highlights: • The mechanical properties of CP Ti grade 1 porous structures are studied. • The results are compared with identical structures in Ti6Al4V ELI and tantalum. • Ti6Al4V ELI structures are about two times stronger under a static compressive load. • CP Ti structures deform continuously without fracture while loaded statically. • CP Ti structures have a higher fatigue life compared to Ti6Al4V ELI structures

    To gain a deeper comprehension of current vulvovaginal atrophy (VVA) knowledge among Spanish postmenopausal women. An online survey (REVIVE) was conducted in four European countries with an overall sample of 768 participants included in Spain. Perceptions, experiences and needs of Spanish postmenopausal women in terms of sexual and vaginal health were reported. Vaginal dryness was the most common VVA symptom in Spain (81%). The severity of symptoms reported by postmenopausal women tended to be similar or worse than at onset, especially in the most troublesome symptom, dyspareunia (80%). VVA symptoms significantly impact on Spanish participants' ability to achieve sexual enjoyment (75%), relationship with partner (67%) and sexual spontaneity (66%). Although 71% of participants with partners (83%) were sexually active, their sex drive was reduced by one-third as a consequence of VVA. Despite the fact that women expected doctors to start asking them about menopausal symptoms, this rarely occurred. Treatments were administered mainly vaginally without prescription (62% were using over-the-counter products at the time). Postmenopausal women who had discussed their symptoms with physicians were twice as likely to be treated (66% vs. 33%) than those who had not. Low compliance with treatment was justified by Spanish participants with not bothersome enough symptoms (22%), relief (21%), inability to reverse vaginal changes (15%) and treatment price (13%). Almost half of the participants with a current local estrogen prescription showed satisfaction. The acknowledged main limitation for all treatments was the inability to restore the natural conditions of the vagina. The price of over-the-counter products was also reported as an important concern in Spanish postmenopausal women. VVA remains underdiagnosed and undertreated in Spain, despite its high frequency and significant impact on quality of life. Since patient satisfaction with available treatments remains compromised

    The authors think that the destructive factors that influence one's destiny in life could be the transmissions of collective, familial, and other factors coming from the clan system. This transmission is described by the concept of transgenerational trauma. A burdensome heritage can either directly, or indirectly, be passed on, even through several generations, as it can be seen in the presented cases. Also cases of intrauterine catastrophes are presented. A catastrophe like this is the case of vanishing twins. Four psychotherapy cases are analyzed in which the patients' sufferings may be attributed to the intrauterine death of their twin. In two of the cases the loss of a twin sibling is a proven biological fact. In the other two cases there is a high probability that the same has happened. A novel element introduced by the authors in the interpretation of this phenomenon is the concept that the fetus and the embrio may be able to preserve the memories of the experienced catastrophes, which as state-dependent memories will be revived in stress situations in the form of physical symptoms and feelings connected to the trauma. However, at this point in time traditional medical thinking is unable to explain the process through which a burdensome heritage is taken over from previous generations. The authors present Bert Hellinger's family constellation and Rupert Sheldrake's theory of morphic resonance as well as the uncertainty principle of quantum psychology. All these consider the multi-dimensional, topological reality that is beyond time and not the four-dimensional geometrical space as the medium in which transgenerational pieces of information spread.

    Anxiety states and anxiety-related behaviors appear to be regulated by a distributed and highly interconnected system of brain structures including the basolateral amygdala. Our previous studies demonstrate that exposure of rats to an open-field in high- and low-light conditions results in a marked increase in c-Fos expression in the anterior part of the basolateral amygdaloid nucleus (BLA) compared with controls. The neural mechanisms underlying the anatomically specific effects of open-field exposure on c-Fos expression in the BLA are not clear, however, it is likely that this reflects activation of specific afferent input to this region of the amygdala. In order to identify candidate brain regions mediating anxiety-induced activation of the basolateral amygdaloid complex in rats, we used cholera toxin B subunit (CTb) as a retrograde tracer to identify neurons with direct afferent projections to this region in combination with c-Fos immunostaining to identify cells responding to exposure to an open-field arena in low-light (8-13 lux) conditions (an anxiogenic stimulus in rats). Adult male Wistar rats received a unilateral microinjection of 4% CTb in phosphate-buffered saline into the basolateral amygdaloid complex. Rats were housed individually for 11 days after CTb injections and handled (HA) for 2 min each day. On the test day rats were either, 1) exposed to an open-field in low-light conditions (8-13 lux) for 15 min (OF); 2) briefly HA or 3) left undisturbed (control). We report that dual immunohistochemical staining for c-Fos and CTb revealed an increase in the percentage of c-Fos-immunopositive basolateral amygdaloid complex-projecting neurons in open-field-exposed rats compared with HA and control rats in the ipsilateral CA1 region of the ventral hippocampus, subiculum and lateral entorhinal cortex. These data are consistent with the hypothesis that exposure to the open-field arena activates an anxiety-related neuronal system with convergent input to the

    2007-01-01

    We perform a one-parameter family of self-adjoint extensions characterized by the parameter ω 0 . This allows us to get generic boundary conditions for the quantum oscillator on N-dimensional complex projective space (CP N ) and on its non-compact version, i.e., Lobachewski space (L N ) in the presence of a constant magnetic field. As a result, we get a family of energy spectra for the oscillator. In our formulation the already known result of this oscillator also belongs to the family. We have also obtained an energy spectrum which preserves all the symmetries (full-hidden symmetry and rotational symmetry) of the oscillator. The method of self-adjoint extensions has also been discussed for a conic oscillator in the presence of the constant magnetic field

    There are a limited number of studies comparing the Aperio mechanical thrombectomy device to other stent-based devices. In this paper, we compared the Aperio thrombectomy device to the Solitaire AB, FR and Revive devices in a model of the middle cerebral artery (MCA) within a modified pulsatile flow system. Thrombi made of lamb's blood were placed into a pulsatile flow system perfused with Hartmann's solution at 80 bpm with a mean pressure of 90 mm Hg. 30 experiments were run with each device. Recanalization rates were similar for all three devices (90% with the Solitaire AB, FR, 80% with the Revive, and 90% with the Aperio). The mean number of attempts to retrieve the thrombus was also similar for all three devices (1.7 with the Solitaire AB, FR, 2.1 with the Revive, 1.6 with the Aperio). Clot fragmentation and embolization rates revealed no statistical significance but there was a trend towards lower embolization rates with the Aperio (23% compared to 40% with the Solitaire AB, FR and 47% with the Revive). The Aperio was the fastest to recanalize the MCA (mean of 66 seconds compared to 186 seconds for the Solitaire AB, FR and 169 seconds for the Revive). In this in vitro setting, the Aperio device seems to be an efficacious and safe device when compared to other similar clinically used mechanical thrombectomy devices. Larger clinical trials are warranted.

    Out-of-home care (OoHC) refers to young people removed from their families by the state because of abuse, neglect or other adversities. Many of the young people experience poor mental health and social function before, during and after leaving care. Rigorously evaluated interventions are urgently required. This publication describes the protocol for the Ripple project and notes early findings from a controlled trial demonstrating the feasibility of the work. The Ripple project is implementing and evaluating a complex mental health intervention that aims to strengthen the therapeutic capacities of carers and case managers of young people (12-17 years) in OoHC. The study is conducted in partnership with mental health, substance abuse and social services in Melbourne, with young people as participants. It has three parts: 1. Needs assessment and implementation of a complex mental health intervention; 2. A 3-year controlled trial of the mental health, social and economic outcomes; and 3. Nested process evaluation of the intervention. Early findings characterising the young people, their carers and case managers and implementing the intervention are available. The trial Wave 1 includes interviews with 176 young people, 52% of those eligible in the study population, 104 carers and 79 case managers. Implementing and researching an affordable service system intervention appears feasible and likely to be applicable in other places and countries. Success of the intervention will potentially contribute to reducing mental ill-health among these young people, including suicide attempts, self-harm and substance abuse, as well as reducing homelessness, social isolation and contact with the criminal justice system.

    To investigate whether mammalian thioredoxin (Trx) and thioredoxin reductase (TrxR), with or without alpha-crystallin can revive inactivated glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in both the cortex and nucleus of human aged clear and cataract lenses. The lens cortex (including capsule-epithelium) and the nucleus were separated from human aged clear and cataract lenses (grade II and grade IV) with similar average age. The activity of GAPDH in the water-soluble fraction after incubation with or without Trx or/and TrxR for 60 min at 30 degrees C was measured spectrophotometrically. In addition, the effect of a combination of Trx/TrxR and bovine lens alpha-crystallin was investigated. GAPDH activity was lower in the nucleus of clear lenses than in the cortex, and considerably diminished in the cataractous lenses, particularly in the nucleus of cataract lenses grade IV. Trx and TrxR were able to revive the activity of GAPDH markedly in both the cortex and nucleus of the clear and cataract lenses. The percentage increase of activity in the cortex of the clear lenses was less than that of the nucleus in the presence of Trx and TrxR, whereas it was opposite in the cataract lenses. The revival of activity in both the cortex and nucleus from the cataract lenses grade II was higher than that of the grade IV. Moreover, Trx alone, but not TrxR, efficiently enhanced GAPDH activity. The combination of Trx and TrxR had greater effect than that of either alone. In addition, alpha(L)-crystallin enhanced the activity in the cortex of cataract grade II with Trx and TrxR present. However, it failed to provide a statistically significant increase of activity in the nucleus. This is the first evidence to show that mammalian Trx and TrxR are able to revive inactivated GAPDH in human aged clear and cataract lenses, and alpha-crystallin helped this effect. The inactivation of GAPDH during aging and cataract development must be caused in part by disulphide formation and in part by

    This report presents predictions of tracer transport in interwell tracer tests that are to be conducted at the C-Hole complex at the Nevada Test Site on behalf of the Yucca Mountain Site Characterization Project. The predictions are used to make specific recommendations about the manner in which the tracer test should be conducted to best satisfy the needs of the Project. The objective of he tracer tests is to study flow and species transport under saturated conditions in the fractured tuffs near Yucca Mountain, Nevada, the site of a potential high-level nuclear waste repository. The potential repository will be located in the unsaturated zone within Yucca Mountain. The saturated zone beneath and around the mountain represents the final barrier to transport to the accessible environment that radionuclides will encounter if they breach the engineered barriers within the repository and the barriers to flow and transport provided by the unsaturated zone. Background information on the C-Holes is provided in Section 1.1, and the planned tracer testing program is discussed in Section 1.2

    To report the initial use of a novel thrombectomy device for revascularization of below-the-knee thromboembolic occlusions encountered during proximal revascularization procedures. The ReVive PV Peripheral Thrombectomy Device is a non-detachable, self-expanding stent-like device recently approved for peripheral thrombectomy. Four patients (3 women; mean age 68.8 years) undergoing proximal revascularization procedures experienced embolic occlusions of all 3 trifurcation vessels in 1 patient, the tibioperoneal trunk alone in 2 cases, and the peroneal artery alone in the last patient. In all cases, the involved arteries represented the primary or sole vessel(s) providing outflow to the lower extremity. In each case, the ReVive PV device was used to successfully extract the thrombus and restore flow to the distal extremity. No complications were encountered during any of the procedures. The ReVive PV peripheral thrombectomy device may facilitate the safe and efficient revascularization of distal arterial embolic occlusions.

    2015-01-01

    This paper analyses the revival of Pliny's Naturalis historia within the scientific culture of the late eighteenth and early nineteenth centuries, focusing on a French effort to produce an edition with annotations by scientists and scholars. Between the Renaissance and the early eighteenth century, the Naturalis historia had declined in scientific importance. Increasingly, it was relegated to the humanities, as we demonstrate with a review of editions. For a variety of reasons, however, scientific interest in the Naturalis historia grew in the second half of the eighteenth century. Epitomizing this interest was a plan for a scientifically annotated, Latin-French edition of the Naturalis historia. Initially coordinated by the French governmental minister Malesherbes in the 1750s, the edition was imperfectly realized by Poinsinet a few decades later. It was intended to rival two of the period's other distinguished multi-volume books of knowledge, Diderot and D'Alembert's Encyclopédie and Buffon's Histoire naturelle, to which we compare it. Besides narrating the scientific revival of the Historia naturalis during this period, we examine its causes and the factors contributing to its end in the first half of the nineteenth century.

Although in certain parameter regimes the quantum state of the system is known to evolve into macroscopic superposition, i.e., Schroedinger cat state, of two states with relative atom number differences between the two components, the Schroedinger cat state is also found to repeat the collapse and revival behavior in the long-time region. The dynamical behavior of the Pegg-Barnett phase difference between the two components is shown to be closely connected with the dynamics of the relative atom number difference for different parameters. The variation in the relative magnitude between the Josephson coupling and intra- and inter-component two-body interaction difference turns out to significantly change not only the size of the Schroedinger cat state but also its collapse-revival period, i.e., the lifetime of the Schroedinger cat state

    The REVIVE randomized controlled trial (RCT) investigated the effectiveness of an individually tailored (personalized) exercise program for patients discharged from hospital after critical illness. By including qualitative methods, we aimed to explore patients' perceptions of engaging in the exercise program. Patients were recruited from general intensive care units in 6 hospitals in Northern Ireland. Patients allocated to the exercise intervention group were invited to participate in this qualitative study. Independent semistructured interviews were conducted at 6 months after randomization. Interviews were audio-recorded, transcribed, and content analysis used to explore themes arising from the data. Of 30 patients allocated to the exercise group, 21 completed the interviews. Patients provided insight into the physical and mental sequelae they experienced following critical illness. There was a strong sense of patients' need for the exercise program and its importance for their recovery following discharge home. Key facilitators of the intervention included supervision, tailoring of the exercises to personal needs, and the exercise manual. Barriers included poor mental health, existing physical limitations, and lack of motivation. Patients' views of outcome measures in the REVIVE RCT varied. Many patients were unsure about what would be the best way of measuring how the program affected their health. This qualitative study adds an important perspective on patients' attitude to an exercise intervention following recovery from critical illness, and provides insight into the potential facilitators and barriers to delivery of the program and how programs should be evolved for future trials.

    The Rey-Osterrieth Complex Figure (ROCF) and the Free and Cued Selective Reminding Test (FCSRT) are widely used in clinical practice. The ROCF assesses visual perception, constructional praxis, and visuo-spatial memory. The FCSRT assesses verbal learning and memory. In this study, as part of the Spanish normative studies project in young adults (NEURONORMA young adults), we present age- and education-adjusted normative data for both tests obtained by using linear regression techniques. The sample consisted of 179 healthy participants ranging in age from 18 to 49 years. We provide tables for converting raw scores to scaled scores in addition to tables with scores adjusted by socio-demographic factors. The results showed that education affects scores for some of the memory tests and the figure-copying task. Age was only found to have an effect on the performance of visuo-spatial memory tests, and the effect of sex was negligible. The normative data obtained will be extremely useful in the clinical neuropsychological evaluation of young Spanish adults. Copyright © 2011 Sociedad Española de Neurología.

    We have invited professional papers from over the world, including Okinawa, for compilation of recent trends on Sterile Insect Techniques and Area-Wide Integrated Pest Management to further pursue environment friendly pest insects control measures in agricultural production in the Asia-Pacific region. Pest insects such as the tephritid fruit flies have long been and are still today causing serious damage to agricultural products in the Asia-Pacific region and farmers in the region apply such insecticides that are no longer allowed or being subjected to strict usage control in Japan. This, in return, may endanger the health of the very farmers, food safety and the ecosystem itself. The purpose of this report is, therefore, to clarify keys for technology transfer of so called SIT/AWIPM to potential recipients engaged in agricultural production in the region. This report focused on several topics, which make up important parts for the effective Sterile Insect Technique and Area-Wide Integrated Pest Management: economic feasibility; pest insects control projects; farmers' education; research progress in Bactrocera dorsalis complex issues specific to the Asia-Pacific region. The 12 of the papers are indexed individually. (J.P.N.)

    Tourist development has been an increasingly popular part in rural construction in contemporary China, and has become a juncture of rural renewal and revival. Taking the three perspectives of rural physical form, rural culture, human action and activities, this article summarizes the problems and conflicts created by Chinese rural tourism, and analyzes the root reason for the conflicts. We try to generalize valuable experience learned from Chinese New Village experimental base so far from different aspects such as architectural forms, spatial scales, ecological environment, arts and culture and residential life, integrated with notion of ‘adaptability design’ in the theoretical system of sustainable development, and then deduct a strategy for designing rural sustainable development, under the intervention of tourism. Lastly, the example of a Chinese village - Fenshui Village is chosen to practice, and construction conception is raised accordingly.

    The effects of spaceflight on cardiovascular health are not necessarily seen immediately after astronauts have returned but can be delayed. It is important to investigate the long term effects of spaceflight on protein and gene expression of inflammation and endothelial activation as a predictor for the development of atherosclerosis and potential cardiovascular problems. The objectives of this study were to investigate the (a) protein and gene expression of inflammation and endothelial activation, (b) expression of nuclear factor kappa B (NFκB), signal transducer and activator of transcription-3 (STAT-3) and endothelial nitric oxide synthase (eNOS) in human umbilical vein endothelial cells (HUVEC) 3 months post-space flight travel compared to ground controls. HUVEC cultured on microcarriers in fluid processing apparatus were flown to the International Space Station (ISS) by the Soyuz TMA-11 rocket. After landing, the cells were detached from microcarriers and recultured in T-25 cm(2) culture flasks (Revived HUVEC). Soluble protein expression of IL-6, TNF-α, ICAM-1, VCAM-1 and e-selectin were measured by ELISA. Gene expression of these markers and in addition NFκB, STAT-3 and eNOS were measured. Spaceflight induced IL-6 and ICAM-1 remain elevated even after 3 months post spaceflight travel and this is mediated via STAT-3 pathway. The downregulation of eNOS expression in revived HUVEC cells suggests a reduced protection of the cells and the surrounding vessels against future insults that may lead to atherosclerosis. It would be crucial to explore preventive measures, in relation to atherosclerosis and its related complications.

    Phase collapse and revival for Bose-Einstein condensates are nonlinear phenomena appearing due to atomic collisions. While it has been observed in a general setting involving many modes, for one-mode condensates its occurrence is forbidden by the particle number superselection rule (SSR), which arises because there is no phase reference available. We consider a single mode atomic Bose-Einstein condensate interacting with an off-resonant optical probe field. We show that the condensate phase revival time is dependent on the atom-light interaction, allowing optical control on the atomic collapse and revival dynamics. Incoherent effects over the condensate phase are included by considering a continuous photo-detection over the probe field. We consider conditioned and unconditioned photo-counting events and verify that no extra control upon the condensate is achieved by the probe photo-detection, while further inference of the atomic system statistics is allowed leading to a useful test of the SSR on particle number and its imposition on the kind of physical condensate state.

    Full Text Available The article examines the history of Jama‘ah Tabligh in Southeast Asia, especially in Kuala Lumpur and Aceh. The author traces the historical background of this religious movement with particular reference to the birth place of Jama‘ah Tabligh, India. The author investigates the major role of Indian in disseminating Islam in Southeast Asia, especially in Malaysia and Indonesia. Many scholars believe that Islam came to Southeast Asia from India (Gujarat, and this is the reason why many Islamic traditions in this region were influenced by Indian culture. However, to analyze Islamic movement in Southeast Asia one should take into consideration the Middle East context in which various Islamic movements flourished. Unlike many scholars who believe that the spirit of revivalism or Islamic modernism in Southeast Asia was more influenced by Islam in the Middle East than Indian, the author argues that the influence of Indian Muslim in Southeast Asia cannot be neglected, particularly in the case of Jama‘ah Tabligh.

  15. The American-European difference in vulvar and vaginal atrophy views: a lesson from the REVIVE Survey.

    2016-06-01

    Vulvar and vaginal atrophy (VVA) is a common complaint in postmenopausal women and consists of a variety of symptoms and strong repercussions that negatively affect comfort during sexual activity and ultimately impact quality of life. The EU and US REVIVE surveys have detected significant barriers in health-care professional management and educational programs that prevent correct diagnosis and effective treatment. This was common in both Europe and the US, but differential behaviors and patterns could be detected after reviewing the published results. The frequency of reporting VVA symptoms was lower in European participants. However, a better knowledge that VVA is a consequence of menopause was evident in Europe, probably in relation to more frequent gynecological visits and more frequent specialist visits as a referral health-care professional. Moreover, a trend towards an improved satisfaction with management by the health-care professional was observed in Europe. European participants acknowledged a significantly higher impact of VVA symptoms on sexual intercourse and partner interaction than North American (US) participants, and both cohorts were observed to have differences between their respective VVA symptom profiles. These observations have implications in the overall concerns that participants stated with long-term VVA medication and for the optimal therapeutic approach, providing evidence to support the concept that unexplored methods to improve management of patients with VVA remain.

    2010-01-01

    Background VADs are used to bridge heart failure patients to transplantation, to allow their own hearts to recover, or as permanent (“destination”) therapy. To date, the use of VADs has been limited to late-stage heart failure patients because of the associated device risks. In 2008, an NHLBI working group met to evaluate the treatment of heart failure using VADs and to advise the institute on how therapy for heart failure may be best advanced by clinical trials involving the devices. Discussion and Recommendations Recognizing the improvements in VAD technology and in patient care and selection over the past decade, the working group recommended that a trial be performed to assess the use of chronic VAD therapy in patients who are less ill than those currently eligible for destination therapy. The hypothesis proposed for the trial is that VAD therapy may improve both survival and quality of life in moderately advanced heart failure patients who are neither inotrope-dependent nor exercise-intolerant and have not yet developed serious consequences such as malnourishment, end-organ damage, and immobility. Based on the group’s recommendations, NHLBI issued an RFP in 2009 for the REVIVE-IT Pilot Trail which will serve to test the hypothesis and inform the pivotal trial. PMID:21055648

    2006-01-01

    This article provides information and a commentary on trials presented at the American Heart Association meeting held in November 2005, relevant to the pathophysiology, prevention and treatment of heart failure. All reports should be considered as preliminary data, as analyses may change in the final publication. In REPAIR-AMI an improvement in ejection fraction was observed in post-MI patients following infusion of bone marrow stem cells. However, the ASTAMI study showed no benefit of stem cell implantation in a similar patient cohort. The JELIS study reported a reduction in major coronary events in patients receiving statins plus fish oil compared to statins alone. MEGA showed that low dose statins in a low risk population reduce the incidence of major cardiovascular events. Two studies of levosimendan in acute heart failure gave conflicting results, in the REVIVE-II study levosimendan was reported to have a superior effect on the composite primary outcome compared to placebo, however, in SURVIVE despite a trend to early benefit with levosimendan, there was no difference in effect on long-term outcome versus dobutamine. The PROACTIVE study showed encouraging results for the use of pioglitazone in post-myocardial infarction patients with concomitant type 2 diabetes.

Stress is laid on the fact that thermography is of great significance for diagnosing dextrocerebral hemorrhagic insult with a manifestation of pronounced hemihypothermia in the paralyzed limbs, identifying paraorbital hyperthermia on the side of rhinogenous cerebral abscess, for instrumental registration of transitory heat-up of the nasolabial region in the case of patients suffering from hypertensive nasal bleeding. Much attention is given to diagnosis of intra- and extracerebral phlebopathy in urgent neurology -- early diagnosis of iatrogenic catheterization phlebitis, interference with the venous return in the paralyzed lower limb. The novelty here is the employment of telethermography for complex diagnosis of cerebral death.

  19. Space and the complexity of European rules and policies: The common projects Galileo and GMES—precedence for a new European legal approach?

    The two European flagship space projects, Galileo and GMES, clearly show that the current existing legal rules of the two organisations involved (European Union and European Space Agency) are not compatible. Moreover, it is quite impossible to implement a common project if every single organisation insists on the application of its own rules strictu sensu. Nevertheless, due to the political desire to advance these projects rapidly and to make them a success, legal obstacles were to be overcome. Consequently, recently concluded agreements between ESA and the EU-Commission concerning the financial and governmental matters of the Galileo and GMES implementation feature a new approach to cooperation between these two organisations. However, the question remains if they can be taken as precedence for a future institutionalised cooperation? It follows that the agreements have to be analysed in order to understand how a mutually acceptable agreement was reached despite the disparity in the rules of both organisations. In this regard, especially the financial decision agreement concerning Galileo in December 2007 shows a very interesting and unique way in applying EU-competition law. In the same way, the GMES-Delegation Agreement of spring 2008 is a good example of how two different legal systems can be applied to make a project success. Additionally, the reasons and arguments of both organisations have to be considered, especially once the Treaty of Lisbon will be in force. As these two main projects of the European Space Policy are characterized by the desire for a successful European cooperation, they can be regarded as an important step forward for a new legal approach. A new system emerges which could be taken into consideration for further common projects undertaken by ESA and the EU.

    In control rooms there are often problems with information overload, which means that the operators may receive more information than they are able to interpret. The most serious information overload occurs in two types of situations. The first is when the operating state of the plant changes, which often gives raise to a shower of alarms and events. Such an alarm shower is expected, but can be dangerous, because it may hide other alarms originating from unrelated faults. The second problem occurs when a fault causes several consequential faults, leading to a so-called alarm cascade. Because the alarms seldom arrive in correct time order, it can be very difficult to analyze such a cascade, and the information overload occurs in exactly the moment when a potentially dangerous situation starts. In an ongoing project, GoalArt and IFE are cooperating in testing and evaluating GoalArt's methods for alarm reduction and root cause analysis. The testing comprises two specific algorithms, root cause analysis and state-based alarm priority. The GoalArt system has been integrated with the HAMBO simulator so that operators can evaluate the algorithms on-line. (authors)

  1. Reviving the shear-free perfect fluid conjecture in general relativity

    2017-12-01

    Employing a Mathematica symbolic computer algebra package called xTensor, we present (1+3) -covariant special case proofs of the shear-free perfect fluid conjecture in general relativity. We first present the case where the pressure is constant, and where the acceleration is parallel to the vorticity vector. These cases were first presented in their covariant form by Senovilla et al. We then provide a covariant proof for the case where the acceleration and vorticity vectors are orthogonal, which leads to the existence of a Killing vector along the vorticity. This Killing vector satisfies the new constraint equations resulting from the vanishing of the shear. Furthermore, it is shown that in order for the conjecture to be true, this Killing vector must have a vanishing spatially projected directional covariant derivative along the velocity vector field. This in turn implies the existence of another basic vector field along the direction of the vorticity for the conjecture to hold. Finally, we show that in general, there exists a basic vector field parallel to the acceleration for which the conjecture is true.

    Full Text Available This article deals with the financing required to restore and reuse the great architecture of the 1900s, in a time in history when public financial resources are becoming increasingly low and difficult to find. The research addresses the possibility of using crowdfunding through the case study of the reuse project of Torino Esposizioni, an architectural work from the '900, partially used, in a state of decay, despite being recognized by international critics as a work of exceptional value. After the Master Plan had been developed by the Turin Polytechnic in collaboration with the City of Turin, the applicability of crowdfunding was analyzed by a survey to evaluate the willingness of the potential users to contribute to the Torino Esposizioni reuse project. In addition to this, the interest of citizens in the historical value of the Torino Esposizioni and the reuse project that would enhance it has been understood. The survey results have highlighted unexpected unwillingness to contribute to the collective funding of the project. Furthermore, they have revealed not only the lack of knowledge of crowdfunding as a means of financing, but also the lack of awareness of the value of Turin’s historical and modern architectural heritage, of which Torino Esposizioni is an outstanding example, although not the only one.

  3. Scientific Theories and Naive Theories as Forms of Mental Representation: Psychologism Revived

    Science.gov (United States)

    Brewer, William F.

    This paper analyzes recent work in psychology on the nature of the representation of complex forms of knowledge with the goal of understanding how theories are represented. The analysis suggests that, as a psychological form of representation, theories are mental structures that include theoretical entities (usually nonobservable), relationships among the theoretical entities, and relationships of the theoretical entities to the phenomena of some domain. A theory explains the phenomena in its domain by providing a conceptual framework for the phenomena that leads to a feeling of understanding in the reader/hearer. The explanatory conceptual framework goes beyond the original phenomena, integrates diverse aspects of the world, and shows how the original phenomena follow from the framework. This analysis is used to argue that mental models are the subclass of theories that use causal/mechanical explanatory frameworks. In addition, an argument is made for a new psychologism in the philosophy of science, in which the mental representation of scientific theories must be taken into account.

    The Oak Ridge Y-12 National Security Complex housed an area known as the Old Salvage Yard (OSY) that was approximately 7 acres. The OSY was used as an area for the accumulation, processing and storage of scrap metal and equipment from Y-12 operations extending from 1968 until 2009. Areas in the northern sections of OSY also have been used for the storage of used oils containing solvents and the accumulation and recycling or de-heading and crushing of 55-gal metal drums. Scrap metal operations historically involved the accumulation, sorting, storage, public sale or disposal of scrap metal and equipment. Non-containerised storage of scrap metal was routine until 1995 when scrap metal received at OSY was placed in B-24 and B-25 boxes. Under the American Recovery and Reinvestment Act (ARRA), approximately 26,759 cubic meters of scrap metal and debris were removed and disposed at both on and off-site disposal facilities including the on-site, Oak Ridge Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) landfill in 2010 and 2011. This removal action was performed in accordance with a CERCLA Record of Decision (ROD) and a close working relationship with both the U.S. Environmental Protection Agency (EPA) Region IV and Tennessee Department of Environment and Conservation (TDEC). Due to efficiencies and the excellent cooperative relationship forged with EPA Region IV and TDEC for Y-12 ARRA Cleanup Projects, a surplus of funding was available for additional remediation work that was completed in fiscal year (FY) 2011. The underlying OSY soils were targeted for characterization and potential remediation. To expedite these important activities, the U.S. Department of Energy Oak Ridge Environmental Management partnered with the regulators during detailed planning sessions through a variety of means to quickly and efficiently characterize and pinpoint areas requiring remediation according to previous ROD commitments.

    The omission of the name 'Mycobacterium paraffinicum' from the Approved Lists of Bacterial Names was due to phenotypic confusion surrounding a close relationship with Mycobacterium scrofulaceum. Correspondingly, 'M. paraffinicum' strains grew slowly in > 7 days, stained acid-alcohol-fast and produced yellow-pigmented, smooth, waxy colonies in the dark at an optimal temperature of 35°C. However, 'M. paraffinicum' strains demonstrated no activity for urease, nicotinamidase or pyrazinamidase and lacked growth at 42°C, unlike M. scrofulaceum. The mycolic acid pattern, as determined by HPLC, clustered 'M. paraffinicum' with M. scrofulaceum, Mycobacterium avium and Mycobacterium parascrofulaceum. Strains were fully susceptible to linezolid, rifabutin, clarithromycin and amikacin. Examination of the historical reference strain of 'M. paraffinicum', ATCC 12670, and five additional isolates using comparative studies with 16S rRNA, hsp65 and rpoB gene and concatenated sequences showed that they formed a tight taxonomic group that was distinct from similar non-tuberculous mycobacteria. Multilocus enzyme electrophoresis (MEE) analysis confirmed a close association of the five additional isolates with the reference strain of 'M. paraffinicum' with a genetic distance of 0.12 and showed that all six strains were distinct from other closely related species. These genetic results provided unambiguous evidence of the uniqueness of this slowly growing, scotochromogenic species and supported the revival of the name as Mycobacterium paraffinicum (ex Davis, Chase and Raymond 1956) sp. nov., nom. rev. We propose the previously deposited reference strain ATCC 12670(T) =DSM 44181(T) =NCIMB 10420(T), located in collections worldwide, as the type strain.

  6. Primary energy consumption in Germany 2004. Drastic price increases and a revival of the economy are key factors

    Primary energy consumption in Germany in 2004 amounted to approx. 493 million TCE (14,438 petajoule), which is almost unchanged from the year before. Effects increasing consumption as a consequence of the revival of the economy were offset by the attenuating influences of the drastic energy price hikes in the course of the year. The influence of temperature last year was not clear. While the weather was warmer in the heating period than in the same period of time the year before, it was slightly cooler over the whole year because of the comparatively low temperatures in the summer months. While the aggregate output of the economy rose by 1.7%, energy productivity of the economy last year improved by only 0.6% corrected for temperature and inventories. Over the average of the period between 1991 and 2003, the increase had been twice as high, i.e. 1.2%. Gross electricity consumption in 2004 was 0.7% higher than the year before. The aggregate electricity productivity, which had clearly dropped the year before, rose again (+0.9%). Gross electricity generation in 2004 exceeded the level of the previous year by 0.5%. As before, nuclear power is at the top in electricity generation, followed by lignite and hard coal. Electricity generation in wind power plants again grew considerably by nearly one third. The contribution by all renewables to gross electricity production in 2004 is around 9%. Unlike the year before, the electricity market in 2004 was characterized by relatively slight price movement.

    To achieve a deeper understanding of the attitudes and perceptions of Italian post-menopausal women (PMW) regarding vulvo-vaginal atrophy (VVA). As part of the EU REVIVE study, an online survey was conducted in four European countries; the Italian arm comprised 1000 participants from representative regions of Italy. The perceptions, experiences and needs of Italian PMW in relation to sexual and vaginal health. The most frequent VVA symptom was vaginal dryness (78%). Usually, the severity of symptoms was similar to or worse than when they first appeared. This was particularly true for dyspareunia, the most bothersome symptom (76%). VVA symptoms had a significant impact on Italian participants' ability to achieve pleasurable relations (74%) and spontaneity (70%). Although 75% of participants were still sexually active, their sex drive had been reduced by a third because of VVA. Women expected that doctors would start a discussion of menopausal symptoms and sexual health, but this was rarely the case (11%). Most women had been treated with a vaginal over-the-counter (OTC) product. Women who had discussed their condition with a physician were more likely (68%) to be under treatment for VVA than those who had not (36%). Low compliance was associated with symptom improvement (23%), not having annoying symptoms (22%), and the impossibility if restoring the vagina to normal (14%). Common reasons for treatment dissatisfaction were related to route of administration or discomfort. Lack of efficacy and fear of a hormone effect were perceived as the main limitations for OTC and local estrogen products, respectively. Despite the commonness of VVA and its significant impact on quality of life, the condition remains underdiagnosed in Italy. Discussion of symptoms with doctors influences the diagnosis, and patients' satisfaction with available treatments is not high. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

  8. Subpopulations of somatostatin-immunoreactive nonpyramidal neurons in the amygdala and adjacent external capsule project to the basal forebrain: evidence for the existence of GABAergic projection neurons in the cortical nuclei and basolateral nuclear complex

    Full Text Available The hippocampus and amygdala are key structures of the limbic system whose connections include reciprocal interactions with the basal forebrain (BF. The hippocampus receives both cholinergic and GABAergic afferents from the medial septal area of the BF. Hippocampal projections back to the medial septal area arise from nonpyramidal GABAergic neurons that express somatostatin (SOM, calbindin (CB, and neuropeptide Y (NPY. Recent experiments in our lab have demonstrated that the basolateral amygdala, like the hippocampus, receives both cholinergic and GABAergic afferents from the BF. These projections arise from neurons in the substantia innominata and ventral pallidum. It remained to be determined, however, whether the amygdala has projections back to the BF that arise from GABAergic nonpyramidal neurons. This question was investigated in the present study by combining Fluorogold (FG retrograde tract tracing with immunohistochemistry for GABAergic nonpyramidal cell markers, including SOM, CB, NPY, parvalbumin, calretinin, and glutamic acid decarboxylase (GAD. FG injections into the basal forebrain produced a diffuse array of retrogradely labeled neurons in many nuclei of the amygdala. The great majority of amygdalar FG+ neurons did not express nonpyramidal cell markers. However, a subpopulation of nonpyramidal SOM+ neurons, termed long range nonpyramidal neurons (LRNP neurons, in the external capsule, basolateral amygdala, and cortical and medial amygdalar nuclei were FG+. About one-third of the SOM+ LRNP neurons were CB+ or NPY+, and one-half were GAD+. It remains to be determined if these inhibitory amygdalar projections to the BF, like those from the hippocampus, are important for regulating synchronous oscillations in the amygdalar-BF network.

    The Framework for Interdisciplinary Design Optimization (FIDO) is a general programming environment for automating the distribution of complex computing tasks over a networked system of heterogeneous computers. For example, instead of manually passing a complex design problem between its diverse specialty disciplines, the FIDO system provides for automatic interactions between the discipline tasks and facilitates their communications. The FIDO system networks all the computers involved into a distributed heterogeneous computing system, so they have access to centralized data and can work on their parts of the total computation simultaneously in parallel whenever possible. Thus, each computational task can be done by the most appropriate computer. Results can be viewed as they are produced and variables changed manually for steering the process. The software is modular in order to ease migration to new problems: different codes can be substituted for each of the current code modules with little or no effect on the others. The potential for commercial use of FIDO rests in the capability it provides for automatically coordinating diverse computations on a networked system of workstations and computers. For example, FIDO could provide the coordination required for the design of vehicles or electronics or for modeling complex systems.

    Full Text Available Modern management theory treats all complex tasks and duties like projects and make these projects possible to be managed by a particular organizational-management concept in order to achieve a goal effectively. A large number of jobs and tasks performed in the system of defense or for defense purposes have the characteristics of projects. Project management is both a skill and a science of monitoring human, material, financial, energy and other resources to achieve required objectives within the given limits: deadlines, time, budget, possibility of realization and the satisfaction of the interests of all project participants. Project management is a traditional area of applied (or functional management focused on managing complex and uncertain situations with defined goals. Introduction In conditions of rapid change and high uncertainty, only adaptive organizations survive, i. e. those that are able not only to react quickly to changes but also to proactively take advantage of changes. Development of project management The biggest influence on the development of the area had complex jobs within the engineering profession. In parallel with the traditional approach new approaches began to develop, while the traditional one still remained in use. Contrary to the traditional engineering approach, a dynamic model first developed in order to respond to demands for greater control of costs. Project management Project management is a skill and knowledge of human and material resources to achieve set objectives within prescribed limits: deadlines, time, budget, possibility of realization, and the satisfaction of all participants in the project. In order to realize a project effectively, it is necessary to manage it rationally. Planning and project management A project plan is a document that allows all team members insight on where to go, when to start and when to arrive, what is necessary to be done in order to achieve the project objectives and what

    We describe the anatomy of the nerves that project from the central nervous system (CNS) to the pro- and mesothoracic segments and the cephalopharyngeal skeleton (CPS) for third instar Calliphora larvae. Due to the complex branching pattern we introduce a nomenclature that labels side branches of first and second order. Two fine nerves that were not yet described are briefly introduced. One paired nerve projects to the ventral arms (VAs) of the CPS. The second, an unpaired nerve, projects to the ventral surface of the cibarial part of the esophagus (ES). Both nerves were tentatively labeled after the structures they innervate. The antennal nerve (AN) innervates the olfactory dorsal organ (DO). It contains motor pathways that project through the frontal connectives (FC) to the frontal nerve (FN) and innervate the cibarial dilator muscles (CDM) which mediate food ingestion. The maxillary nerve (MN) innervates the sensory terminal organ (TO), ventral organ (VO), and labial organ (LO) and comprises the motor pathways to the mouth hook (MH) elevator, MH depressor, and the labial retractor (LR) which opens the mouth cavity. An anastomosis of unknown function exists between the AN and MN. The prothoracic accessory nerve (PaN) innervates a dorsal protractor muscle of the CPS and sends side branches to the aorta and the bolwig organ (BO) (stemmata). In its further course, this nerve merges with the prothoracic nerve (PN). The architecture of the PN is extremely complex. It innervates a set of accessory pharyngeal muscles attached to the CPS and the body wall musculature of the prothorax. Several anastomoses exist between side branches of this nerve which were shown to contain motor pathways. The mesothoracic nerve (MeN) innervates a MH accessor and the longitudinal and transversal body wall muscles of the second segment. J. Morphol. 271:969-979, 2010. (c) 2010 Wiley-Liss, Inc.

    Valuable structural information, much of it unavailable by other methods, can be obtained about complexes in solution through NMR spectroscopy. From chemical shift and intensity measurements of complexed species, NMR can serve as a species-specific structural probe for molecules in solution and can be used to validate thermodynamic constants used in geochemical modeling. Fourier-transform nuclear magnetic resonance (FT-NMR) spectroscopy has been employed to study the speciation of uranium(VI) ions in aqueous carbonate solutions as a function of pH, ionic strength, carbonate concentration, uranium concentration, and temperature. Carbon-13 and oxygen-17 NMR spectroscopy were used to monitor the fractions, and hence thermodynamic binding constants of two different uranyl species U0 2 (CO 3 ) 3 4- and (UO 2 ) 3 (CO 3 ) 6 6- in aqueous solution. Synthetic buffer solutions were prepared under the ionic strength conditions used in the NMR studies in order to obtain an accurate measure of the hydrogen ion concentration, and a discussion of pH = -log(a H + ) versus p[H] = -log[H+] is provided. It is shown that for quantitative studies, the quantity p[H] needs to be used. Fourteen uranium(VI) binding constants recommended by the OECD NEA literature review were corrected to the ionic strengths employed in the NMR study using specific ion interaction theory (SIT), and the predicted species distributions were compared with the actual species observed by multinuclear NMR. Agreement between observed and predicted stability fields is excellent. This establishes the utility of multinuclear NMR as a species-specific tool for the study of the actinide carbonate complexation constants, and serves as a means for validating the recommendations provided by the OECD NEA

    This document gathers several articles published by Le Monde. The first one comments the opposition of local authorities to the project of restart of 48 Japanese nuclear reactors which have been stopped after the Fukushima accident. A second one discusses the comments made by the IAEA on the progress made by decontamination activities and on its diagnosis of a still very complex situation around Fukushima (the problem of contaminated waters and damaged vessels is notably outlined, as well as the problem of contamination of the Pacific Ocean and measures aimed at limiting this contamination); the issue of poisoned fish and the problem of extraction of contaminated fuel bars are also evoked. The third and fourth articles outline that, despite the opposition of the Japanese opinion and also some political and legal factors (withholding of information, issue of seismic risk), the restart of Japanese nuclear reactors seems to be established, and describe the situation and the commitment of the local population at the vicinity of the Sendai power station. The last article describes the case of the town of Nahara which had been totally evacuated after the Fukushima accident, and is now officially inhabitable again, even though fears are still present

    The presently active region of the Congo deep-sea fan (around 330,000 km2), called the terminal lobes or lobe complex, covers an area of 2500 km2 at 4700-5100 m water depth and 750-800 km offshore. It is a unique sedimentary area in the world ocean fed by a submarine canyon and a channel-levee system which presently deliver large amounts of organic carbon originating from the Congo River by turbidity currents. This particularity is due to the deep incision of the shelf by the Congo canyon, up to 30 km into the estuary, which funnels the Congo River sediments into the deep-sea. The connection between the river and the canyon is unique for major world rivers. In 2011, two cruises (WACS leg 2 and Congolobe) were conducted to simultaneously investigate the geology, organic and inorganic geochemistry, and micro- and macro-biology of the terminal lobes of the Congo deep-sea fan. Using this multidisciplinary approach, the morpho-sedimentary features of the lobes were characterized along with the origin and reactivity of organic matter, the recycling and burial of biogenic compounds, the diversity and function of bacterial and archaeal communities within the sediment, and the biodiversity and functioning of the faunal assemblages on the seafloor. Six different sites were selected for this study: Four distributed along the active channel from the lobe complex entrance to the outer rim of the sediment deposition zone, and two positioned cross-axis and at increasing distance from the active channel, thus providing a gradient in turbidite particle delivery and sediment age. This paper aims to provide the general context of this multidisciplinary study. It describes the general features of the site and the overall sampling strategy and provides the initial habitat observations to guide the other in-depth investigations presented in this special issue.

The model adopts a modular approach, integrating biophysical modules that simulate natural and engineered phenomena with human modules that represent behavior at multiple levels of decision making. The hydrologic modules are developed using spatially-distributed groundwater and surface water models, which are translated into compact simulators for efficient integration into the multi-agent model. For the groundwater model, we adopt a response matrix method approach in which a 3-dimensional MODFLOW model of a complex regional groundwater system is converted into a linear simulator of groundwater response by pre-processing drawdown results from several hundred numerical simulation runs. Surface water models for each major surface water basin in the country are developed in SWAT and similarly translated into simple rainfall-runoff functions for integration with the multi-agent model. The approach balances physically-based, spatially-explicit representation of hydrologic systems with the efficiency required for integration into a complex multi-agent model that is computationally amenable to robust scenario analysis. For the multi-agent model, we explicitly represent human agency at multiple levels of decision making, with agents representing riparian, management, supplier, and water user groups. The agents' decision making models incorporate both rule-based heuristics as well as economic optimization. The model is programmed in Python using Pynsim, a generalizable, open-source object-oriented code framework for modeling network-based water resource systems. The Jordan model is one of the first applications of Pynsim to a real-world water management case study. Preliminary results from a tanker market scenario run through year 2050 are presented in which several salient features of the water system are investigated: competition between urban and

    During 1998, ANAV began to optimize Human Resources to cope with the ERE and ANA-ANV integration. Project AVE was intended to achieve an orderly transfer of know-how, skills, attitudes and experiences. The most complex part was renovation of personnel with Operating Licenses. Nearly 140 people had joined the organization by late December 2003. This opportunity was seized to draw up a new Training Manual, and a common Initial Training Plan was designed for the two plants, accounting for the singularities of each one. The plan is divided into 5 modules: Common Training, Specific Training, PEI/CAT, Management, and on-the-job Training. The training environments were defined according to the nature of the capabilities to be acquired. Project AVE resulted in the merger of the Asco and Vandellos II Training services. (Author)

    Iclaprim, a diaminopyrimidine antibiotic, was compared with vancomycin for the treatment of patients with acute bacterial skin and skin structure infections (ABSSSIs) in two studies (REVIVE-1 and REVIVE-2). We explored the efficacy and tolerability of iclaprim in a pooled analysis of results from both studies. REVIVE-1 and REVIVE-2 were Phase 3, double-blind, randomized (1:1), multicenter, active-controlled, non-inferiority (margin of 10%) trials, each designed to enroll 600 patients a piece with ABSSSI. The studies used identical study protocols. Iclaprim 80 mg and vancomycin 15 mg/kg were administered IV every 12 hours for 5-14 days. The primary endpoint was a ≥20% reduction from baseline in lesion size (early clinical response [ECR]) at the early time point (48 to 72 hours after the start of study drug) in the intent-to-treat population. In REVIVE-1, ECR at the early time point was 80.9% with iclaprim vs. 81.0% with vancomycin (treatment difference, -0.13%; 95% confidence interval, -6.42% to 6.17%). In REVIVE-2, ECR was 78.3% with iclaprim vs. 76.7% with vancomycin (treatment difference: 1.58%, 95% CI: -5.10% to 8.26%). The pooled ECR was 79.6% with iclaprim vs. 78.8% with vancomycin (treatment difference: 0.75%, 95% CI: -3.84 to 5.35%). Iclaprim and vancomycin were comparable for the incidence of mostly mild adverse events, except for a higher incidence of elevated serum creatinine with vancomycin (n=7) compared with iclaprim (n=0). Iclaprim achieved noninferiority compared with vancomycin for early clinical response at the early time point and secondary endpoints with a similar safety profile in two Phase 3 studies for the treatment of ABSSSI suspected or confirmed to be caused by Gram-positive pathogens.

    In less than a decade, Morocco reportedly saw cannabis cultivation decrease by 65%, and hashish production is widely believed to have followed the same trend. Yet large anomalies exist between the alleged fall of hashish production in Morocco and international seizure data. While no explanation for such a discrepancy existed, the main hypothesis was that cannabis cultivation and hashish production had not declined to the extent suggested by the available information. Based on existing data, on interviews with various actors, from European police sources to Moroccan cannabis cultivators, and on field research in Morocco, this article reviews contradictory available data and confronts it with observations made in the field. In the past decade cannabis cultivation underwent radical changes that could explain the discrepancy between official Moroccan cultivation and production data on the one hand, and international seizures on the other hand. The "traditional" kif cannabis variety is being rapidly replaced by hybrids with much larger resin yields and much higher potency. This unnoticed phenomenon, which slowly started in the early 2000s, explains how a two-third decline in cannabis cultivation was at least partially compensated for by three to five-fold yield increases. The fact that the massive ongoing switch to hybrid cultivation is largely unknown or unaccounted for is actually a serious issue, for it directly questions the economic strategies that are being implemented in part to reduce and suppress cannabis cultivation in the Rif.

    According to the author scarcely twenty-five years after the Atoms for Peace proposal, the civilian nuclear landscape that President Reagan inherited was dismal. Among the problems were: numerous reactor plant deferrals or cancellations; a large and expensive high-level waste management program devoted to theoretical studies and rendered impotent; commercial reprocessing frustrated by federal policy and regulatory instability; a large and expensive breeder development program stalled out; and U.S. leadership in international nuclear commerce diluted, a growing reputation of the U.S. as an unreliable supplier. The author believes that underlying each of these maladies lay a common fault - a failure of the institutions, most notably the government, through regulatory and policy instability

    Four years after its occurrence rocked the petroleum industry and revitalized the US environmental movement, the Exxon Valdez tanker oil spill off Alaska continues to stir controversy. Conflicting reports abound over whether there is long term damage to the Prince William Sound ecosystem resulting from the March 24, 1989, spill. Government scientists at recent conferences disclosed studies they contend show long term, significant damage to the sound. Exxon this month launched a counteroffensive, disclosing results of studies it funded that it claims show no credible scientific evidence of long term damage. At the same time, the company blasted as flawed the government's data on assessing environmental damage to the sound and charged that test samples from the sound were mishandled. Meantime, Prince William Sound still shows lingering effects from the Exxon Valdez oil spill. But recovery has been so rapid that there is more controversy over how to use $900 million in natural resource recovery funds that Exxon paid than over how badly species are suffering. The paper describes Exxon's studies; faulty data; lingering damage; and an update on tanker safety

    Recently, laser-scanning technology, especially mobile mapping systems (MMSs), has been applied to measure 3D urban scenes. Thus, it has become possible to simulate a traditional cultural event in a virtual space constructed using measured point clouds. In this paper, we take the festival float procession in the Gion Festival that has a long history in Kyoto City, Japan. The city government plans to revive the original procession route that is narrow and not used at present. For the revival, it is important to know whether a festival float collides with houses, billboards, electric wires or other objects along the original route. Therefore, in this paper, we propose a method for visualizing the collisions of point cloud objects. The advantageous features of our method are (1) a see-through visualization with a correct depth feel that is helpful to robustly determine the collision areas, (2) the ability to visualize areas of high collision risk as well as real collision areas, and (3) the ability to highlight target visualized areas by increasing the point densities there.

  11. Revival of extinct species using nuclear transfer: hope for the mammoth, true for the Pyrenean ibex, but is it time for "conservation cloning"?

    Recent accomplishments in the fields of nuclear transfer and genomics, such as the cloned offspring production from frozen mouse cells, cryopreserved at not too low temperatures without cryoprotectors; or the sequencing of wooly mammoth genome, have opened the opportunity for the revival of extinct species. As expected, they are receiving a lot of publicity in the media and also scientific attention. Furthermore, it was recently published the "revival" of the first extinct subspecie: the Pyrenean ibex (Capra pyrenaica pyrenaica), a wild goat extinct in 2000. This strengthens the field of cloning as it had been tarnished by induced pluripotent stem cells (iPS) and other methods of reprogramming. However, for biological conservation purposes, cloning is not generally accepted as an alternative for animal conservation, and there is an ongoing debate between reproductive scientists and conservation specialists. Although we believe that nuclear transfer technologies have an opportunity in conservation efforts for some species that are on the brink of extinction and that population status, geographical isolation, reproductive characteristics, and human pressure create a situation that is almost unsustainable. In this article we discuss the barriers in cloning mammoths and cloning controversies in conservation from a zoological perspective, citing the species that might benefit from nuclear transfer techniques in the arduous journey so as not to disappear forever from this, our world.

    Italian participants in the European REVIVE survey reported that vaginal and vulvar atrophy (VVA) impaired various aspects of their lives, notably the ability to enjoy sex. The aim of the present study was to explore regional differences in knowledge, experiences, and treatment of VVA in the Italian REVIVE sample (n = 1000), which was analyzed according to region of residence. While many respondents were unfamiliar with the VVA condition, most could relate their VVA symptoms to the menopause. The rate of diagnosis of VVA was twice as high in Central Italy as in the North-East. For individual VVA symptoms, 25.4-41.6% of respondents judged that the symptom had worsened over time. There were no significant regional differences for symptoms in terms of reported rate, change in severity, impact on sexual activity, or health-care visits. Testosterone cream and OTC medication based on hyaluronic acid showed significant regional differences in lifetime rates of use. In Italy, there are modest regional differences in knowledge, diagnosis, and treatment of VVA, some of which may be explained by inter-regional differences in health care. Further efforts are needed to ensure that Italian women are properly informed about VVA and have access to appropriate health care and treatments.

    This project aims to establish production technology of functional substances, oil degradation and purification technology, and use technology of unused oil fraction through development of cultivation control technology of complex biosystems. For functional material production technology, as functional substances some specific marine bacteria inhibitors, antibreeding substances of microalgae, and UV absorption substances were isolated. The productivity of korormicin as specific inhibitor against marine bacteria was improved considerably by cultivation method. For research on molecular genetic analysis technology, a new identification technology and a simple automatic analysis system of microeucaryotes using genes were developed. For global environment purification technology such as efficient degradation of pollutants, study was made on cultivation control technology of phenol- degrading consortia, population dynamics of oil-degrading microbial consortia and a restoration method of oil pollution by complex biosystem at lower temperature, and the demonstration experiment of oil degradation were carried out.
