    1995-11-01

    The Information Management Division (IMD) at LLNL is developing a new purchasing system for the Procurement Department. The first major development of this new system is called, {open_quotes}Total On-Line Purchasing System{close_quotes} (TOPS). TOPS will help speed up the requisitioning process by having requisitions electronically entered by requesters and electronically sent to buyers to be put on Purchase Orders. The new purchasing system will use Electronic Commerce (EC)/Electronic Data Interchange (EDI), to help increase transaction flows for shipping notices, RFQs, Quotes, Purchase Orders, and Invoices. ANSI X.12 is the EDI standard that this new EC will use.

    Subramanian, S; Villez, P A

    1991-01-01

    Order processing and parts issuing are within the scope of an inventory management system and, as such, it was logical to incorporate the Purchase Order Management Menu into the biomedical engineering inventory management system. The Purchase Order Management function was implemented using the services of a biomedical engineering technician who is a staff member. Software development time (two months) was the only resource that was necessary to incorporate this function into the inventory system. This function, implemented on a PC, provided locally functions that had not been available on the mainframe-based hospital purchasing system. These functions directly addressed the needs of the users, who in this case are the staff members of the department of biomedical engineering at University Hospital, Stony Brook, New York.

    Rubin, H; Keller, D D

    1983-01-01

    A method by which a pharmacy department improved its purchasing and inventory control system is described. System changes to the computerized inventory control system included implementation of a formulary, affiliation with a group purchasing association, and transfer of specified purchasing and inventory control functions to the technical staff of the purchasing department. Pharmacy maintained the decision-making authority over all vendors and dosage forms of drug products. Optimal results were achieved when the purchasing department's pharmacy buyer position was staffed with an employee who had previous experience as a clerical worker in the pharmacy. The authors state that this system has proved to be an effective, cost efficient method of purchasing and inventory control of pharmaceuticals in their hospital.

  11. Employee Likelihood of Purchasing Health Insurance using Fuzzy Inference System

    2012-01-01

    Full Text Available Many believe that employees health and economic factors plays an important role in their likelihood to purchase health insurance. However decision to purchase health insurance is not trivial matters as many risk factors that influence decision. This paper presents a decision model using fuzzy inference system to identify the likelihoods of purchasing health insurance based on the selected risk factors. To build the likelihoods, data from one hundred and twenty eight employees at five organizations under the purview of Kota Star Municipality Malaysia were collected to provide input data. Three risk factors were considered as the input of the system including age, salary and risk of having illness. The likelihoods of purchasing health insurance was the output of the system and defined in three linguistic terms of Low, Medium and High. Input and output data were governed by the Mamdani inference rules of the system to decide the best linguistic term. The linguistic terms that describe the likelihoods of purchasing health insurance were identified by the system based on the three risk factors. It is found that twenty seven employees were likely to purchase health insurance at Low level and fifty six employees show their likelihoods at High level. The usage of fuzzy inference system would offer possible justifications to set a new approach in identifying prospective health insurance purchasers.

    2010-10-01

    Recommender system a new marketing strategy plays an important role particularly in an electronic commerce environment. Among the various recommender systems, collaborative recommender system (CRS) is widely used in a number of different applications such as recommending web pages, movies, tapes and items. CRS suffers from scalability, sparsity, and cold start problems. An intelligent integrated recommendation approach using radial basis function network (RBFN) and collaborative filtering (CF), based on Cover’s theorem, is proposed in order to overcome the traditional problems of CRS. The proposed system predicts the trend by considering both likes and dislikes of the active user. The empirical evaluation results reveal that the proposed approach is more effective than other existing approaches in terms of accuracy and relevance measure of recommendations.

    1991-01-01

    This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.

    Grubb, J.W.; Lovin, J.K.; Smith, M.B.; Haese, R.L.; Needham, D.B.; Wilson, J.K.

    1980-08-01

    The ORNL Management Information System (MIS) Direct Purchase Information System (DPIS) is an on-line interactive system of computer programs. The system can provide a manager with commitment and delivery schedule information on current direct purchase requisitions. The commitment data accounts for the orders that have been placed and those requisitions yet to be placed with a vendor. Information can be summarized at many different levels, and individuals can quickly determine the status of their requisitions. DPIS contains data only on active outside direct purchases, but has the capability to access historical data. It provides sufficient flexibility to be used to answer many questions pertinent to the status of these direct purchases and their obligating costs. Even an inexperienced computer user should have little difficulty in learning to use DPIS. The User Module prompts the user on what type of response it is expecting. If the user has doubts as to the response, or if the meaning of the response is not clear, the module will give a detailed list of the options available at that level. The user has control of what data are to be considered, how they are to be grouped, and what format the output will take. As the user selects the options available at a given level, the module proceeds to the next lower level until sufficient input has been supplied to provide the requested information. A major benefit of this interactive, user-oriented system is that the manager can specify the information requirements and does not have to spend time going through a great deal of other data to locate what is needed. Because it is interactive, a search can begin at a summary level and then resort to a more detailed level if needed. DPIS allows the user direct control for selecting the type of commitment data, output, funds, and direct purchase.

    2014-08-01

    The one-more-than technique is an effective strategy for individuals with intellectual disabilities (ID) to use when making purchases. However, the heavy cognitive demands of money counting skills potentially limit how individuals with ID shop. This study employed a multiple-probe design across participants and settings, via the assistance of a mobile purchasing assistance system (MPAS), to assess the effectiveness of the one-more-than technique on independent purchases for items with prices beyond the participants' money counting skills. Results indicated that the techniques with the MPAS could effectively convert participants' initial money counting problems into useful advantages for successfully promoting the independent purchasing skills of three secondary school students with ID. Also noteworthy is the fact that mobile technologies could be a permanent prompt for those with ID to make purchases in their daily lives. The treatment effects could be maintained for eight weeks and generalized across three community settings. Implications for practice and future studies are provided.

    2013-01-01

    Identifying citation classics in the field is one of the key methodologies used to conduct a systematic evaluation of research performance. The objective of this study was to determine the most frequently cited articles published in journals that are placed under the 'respiratory system' subject category (Institute for Scientific Information (ISI) Journal Citation Reports) and to compare them with the most frequently cited respiratory-related articles published in any journal, regardless of subject category. The authors utilized the ISI Journal Citation Reports: Science Edition 2010 database in April 2012 to determine the most frequently cited articles by respiratory system subject category and by respiratory-related keywords. The top 50 most-cited articles were identified in each category and evaluated according to various characteristics. The majority of these papers originated from the United States. The median numbers of citations for the top 50 cited articles stratified by respiratory system subject category and respiratory-related keywords were 841.5 and 2701, respectively. Half of the top 50 cited articles identified by respiratory-related keywords were published in general medical or basic science journals, whereas only three out of these were published in journals under the respiratory system subject category in ISI Journal Citation Reports. In summary, respiratory-related articles published in general medical or science journals attracted more citations than those published in the specific respiratory journals.

  18. Last hurrah for quarkonium physics: the top system

    Energy Technology Data Exchange (ETDEWEB)

    Eichten, E.

    1985-02-01

    The present knowledge about heavy quark systems is applied to the top system - both toponium and open top. Properties of these systems are predicted. What can be learned from toponium about quarkonium physics under realistic experimental conditions is also discussed. The spectrum of toponium states is discussed: the expected excitation spectrum, the implications for probing the heavy quark potential, and an estimate of the fine and hyperfine splittings. Production and decay properties are discussed, particularly emphasizing the growing importance of electroweak effects on the decays of toponium states. The properties of low-lying open top mesons are also dicussed. Some more exotic possibilities are considered, particularly: (1) the influence of light charged or neutral Higgs-like scalars on toponium decays, (2) possible direct production of J = 1 (t anti t) P-states via the axial vector coupling of the Z/sup 0/ to (t anti t), and (3) toponium - Z/sup 0/ interference effects which would result if the mass difference between some toponium resonance and the Z/sup 0/ were less than the width of the Z/sup 0/. The present situation of the nonrelativistic potential between heavy quarks is discussed. 53 refs., 29 figs., (LEW)

  19. [Centralized purchasing of essential drugs, a priority for the health care systems of developing countries].

    Science.gov (United States)

    Blaise, P; Dujardin, B; de Béthune, X; Vandenbergh, D

    1998-01-01

    Health sector reform is a key priority of many governments throughout the world. Drug supply systems are a major element of public health policy design in Africa, where 90% of drugs are imported. The WHO Essential Drugs Program and the UNICEF sponsored Bamako Initiative have, since the late 1980s, promoted the rational use of essential drugs and attempted to ensure a sustainable drug supply through the implementation of cost recovery schemes and quality assurance mechanisms in public health services. A new market for drugs is emerging within this framework and there is growing competition for its control. Government medical stores are all too often bankrupt and the private sector is expensive, catering mainly for the middle to upper classes of urban areas. An intermediate alternative. Essential Drugs Purchasing Offices (EDPOs), has been proposed to balance social objectives and economic constraints. Some of the experimental strategies have given promising results. However, their implementation raises a number of questions: What is the role of the EDPO? Should it promote public health issues in general or focus purely on drug availability? What is the most appropriate legal status? Public or private? For profit or not? How should the investment capital be structured? In drugs or in funds? With ample provision or a tight budget? How should drug purchases be managed? Where should drugs be purchased? How much? How often? According to which procedures? How should the distribution of drugs be organized? Supplying everyone? Pushing supplies or pulling purchasers in? The answers to these questions, analysis of the reasons for success and failure and the dissemination of the information gathered should identify priorities for action and future research and define a framework for expansion. These are the objectives of the "Concerted Action for the Development of EDPO in Sub-Saharan African Countries" which is supported by the European Union (DG XII).

    2013-12-01

    Full Text Available There are a variety of ranking systems for universities throughout the different continents of the world. The majority of the world ranking systems have paid special attention toward evaluation of universities and higher education institutions at the national and international level. This paper tries to study the similarities and status of top Asian universities in the list of top 200 universities by these world ranking systems. Findings show that there are some parallelisms among these international rankings. For example it was found some correlations between QS-Webometrics rankings (R= 0.78; QS-THE rankings (R= 0.53; and Shanghai-HEEACT rankings (R= 0.58. The highest correlation rate belongs to QS-Webometrics (R=0.78. The findings show no evidence to prove that the origin country of ranking system has any bias toward the rank of universities of its own country among other countries. For instance QS ranking of the United States classifies many universities of China and Japan as top Asian universities. HEEACT Ranking System of Taiwan includes just one university of Taiwan in the high ranking category (as other rankings do. Shanghai Ranking of China assigns a lower grade to universities of China and Hong Kong in comparison with QS ranking of the USA. Finally, some suggestions are made to improve the benefits of the ranking systems in order to promote the situation of higher education in the world, and recommendations for combining the indicators of these ranking systems to have a more comprehensive one for the world.

    Point-of-purchase (POP) information at food stores could help promote healthy dietary habits. However, it has been difficult to evaluate the effects of such intervention on customers' behavior. We objectively evaluated the usefulness of POP health information for vegetables in the modification of customers' purchasing behavior by using the database of a point-of-sales (POS) system. Two supermarket stores belonging to the same chain were assigned as the intervention store (store I) and control store (store C). POP health information for vegetables was presented in store I for 60 days. The percent increase in daily sales of vegetables over the sales on the same date of the previous year was compared between the stores by using the database of the POS system, adjusting for the change in monthly visitors from the previous year (adjusted ∆sales). The adjusted ∆sales significantly increased during the intervention period (Spearman's ρ = 0.258, P for trend = 0.006) at store I but did not increase at store C (ρ = -0.037, P for trend = 0.728). The growth of the mean adjusted ∆sales of total vegetables from 30 days before the intervention period through the latter half of the intervention period was estimated to be greater at store I than at store C by 18.7 percentage points (95% confidence interval 1.6-35.9). Health-related POP information for vegetables in supermarkets can encourage customers to purchase and, probably, consume vegetables.

    Terrestrial Observation and Prediction System (TOPS) is a flexible modeling software system that integrates ecosystem models with frequent satellite and surface weather observations to produce ecosystem nowcasts (assessments of current conditions) and forecasts useful in natural resources management, public health and disaster management. We have been extending the Terrestrial Observation and Prediction System (TOPS) to include a capability for automated anomaly detection and analysis of both on-line (streaming) and off-line data. In order to best capture the knowledge about data hierarchies, Earth science models and implied dependencies between anomalies and occurrences of observable events such as urbanization, deforestation, or fires, we have developed an ontology to serve as a knowledge base. We can query the knowledge base and answer questions about dataset compatibilities, similarities and dependencies so that we can, for example, automatically analyze similar datasets in order to verify a given anomaly occurrence in multiple data sources. We are further extending the system to go beyond anomaly detection towards reasoning about possible causes of anomalies that are also encoded in the knowledge base as either learned or implied knowledge. This enables us to scale up the analysis by eliminating a large number of anomalies early on during the processing by either failure to verify them from other sources, or matching them directly with other observable events without having to perform an extensive and time-consuming exploration and analysis. The knowledge is captured using OWL ontology language, where connections are defined in a schema that is later extended by including specific instances of datasets and models. The information is stored using Sesame server and is accessible through both Java API and web services using SeRQL and SPARQL query languages. Inference is provided using OWLIM component integrated with Sesame.

    1992-01-01

    As the nation redefines priorities to deal with a rapidly changing world order, both government and industry require new approaches for oversight of management systems, particularly for high technology products. Declining defense budgets will lead to significant reductions in government contract management personnel. Concurrently, defense contractors are reducing administrative and overhead staffing to control costs. These combined pressures require bold approaches for the oversight of management systems. In the Spring of 1991, the DPRO and TRW created a Process Action Team (PAT) to jointly prepare a Performance Based Management (PBM) system titled Teamwork for Oversight of Processes and Systems (TOPS). The primary goal is implementation of a performance based management system based on objective data to review critical TRW processes with an emphasis on continuous improvement. The processes are: Finance and Business Systems, Engineering and Manufacturing Systems, Quality Assurance, and Software Systems. The team established a number of goals: delivery of quality products to contractual terms and conditions; ensure that TRW management systems meet government guidance and good business practices; use of objective data to measure critical processes; elimination of wasteful/duplicative reviews and audits; emphasis on teamwork--all efforts must be perceived to add value by both sides and decisions are made by consensus; and synergy and the creation of a strong working trust between TRW and the DPRO. TOPS permits the adjustment of oversight resources when conditions change or when TRW systems performance indicate either an increase or decrease in surveillance is appropriate. Monthly Contractor Performance Assessments (CPA) are derived from a summary of supporting system level and process-level ratings obtained from objective process-level data. Tiered, objective, data-driven metrics are highly successful in achieving a cooperative and effective method of measuring

    Full Text Available Purchasing is the management of the company’s external resources in such way that the supply of all goods and services which are necessary for running, maintaining and managing the company’s primary and support activities is secured at the most favourable conditions. Purchasing activitiy in companies has a technical, commercial, logistical and marketing dimention. Mutual overlaping of the areas of purchasing, logistics and marketing is fully justified. All logistical aspects in purchasing activity should be of interest to purchasing and logistics. The same applies to purchasing and marketing. However, it is unjustified to annex purchasing to one or both of the above-mentioned disciplines.

    1992-11-01

    Fragmentation in the delivery of community support services is often identified as a major barrier to persons with severe mental illness, preventing them from living productive lives in the community. In Nassau County, New York, in 1989 a voucher process was created to allow service users to develop individualized support networks by purchasing services directly and by pooling funds to start new services. The voucher process is part of an intensive case management program. Goals set in the individual service plans of users guide voucher purchases. The local Mental Health Association manages funds based on a bank credit card model. The user, the case manager, and a staff member from an agency designated by the user review expenditures quarterly. The first year of operation is described, and suggestions for developing a voucher process, such as the need for extensive retraining of users and providers, are offered.

    Automatic health-monitoring systems for the smart house are being developed for the elderly. An automatic health-monitoring system needs a way of personal recognition when two or more aged persons live together. We propose a personal recognition method based on the space spectrum of the head-top image. We examined 33 head-top images from eleven subjects and achieved a personal recognition rate of 86.4 percent. When one subject with thinning hair was excluded, the personal recognition rate was 90.0 percent in 30 head-top images from ten subjects.

    This research aims to develop snow melting system around steel top of underground fire cistern by using heat pipe, for realizing quick finding of the steel top under heavy snow fall. Water in a fire cistern installed underground is heated by underground heat source, 10 ~15 °C. The iron top is put on snow melting panel made of reinforced concrete. Heat is transported from water to the snow melting panel by heat pipes, which melts snow on it. The experimental results obtained for two years show that this system can melt the snow around the steel top in winter season preferably. The numerical simulation using only weather data was found to predict temperature variations of the whole system with good agreements to the experimental data. Therefore, this simulation software can be used for designing this snow-melting system.

  17. Angular analysis of polarized top quark decay into B-mesons in two different helicity systems

    CERN Document Server

    Nejad, S M Moosavi

    2014-01-01

    We calculate the ${\\cal O}(\\alpha_s)$ radiative corrections to the spin dependent differential decay rates of the process $t\\rightarrow b+W^+$. These are needed to study the angular distribution of the energy of hadrons produced in polarized top quark decays at next-to-leading order (NLO). In our previous work, we studied the angular distribution of the scaled-energy of bottom-flavored hadrons (B) from polarized top quark decays, using a specific helicity coordinate system where the top quark spin was measured relative to the bottom momentum (system~1). Here, we study the angular distribution of the energy spectrum of B-hadron in a different helicity system, where the top spin is specified relative to the W-momentum (system~2). These energy distributions are governed by the polarized and unpolarized rate functions which are related to the density matrix elements of the decay $t\\rightarrow W^++b$. Through this paper, we present our predictions of the B-hadron spectrum in the polarized and unpolarized top decay...

  18. [Barriers to the normalization of telemedicine in a healthcare system model based on purchasing of healthcare services using providers' contracts].

    Science.gov (United States)

    Roig, Francesc; Saigí, Francesc

    2011-01-01

    Despite the clear political will to promote telemedicine and the large number of initiatives, the incorporation of this modality in clinical practice remains limited. The objective of this study was to identify the barriers perceived by key professionals who actively participate in the design and implementation of telemedicine in a healthcare system model based on purchasing of healthcare services using providers' contracts. We performed a qualitative study based on data from semi-structured interviews with 17 key informants belonging to distinct Catalan health organizations. The barriers identified were grouped in four areas: technological, organizational, human and economic. The main barriers identified were changes in the healthcare model caused by telemedicine, problems with strategic alignment, resistance to change in the (re)definition of roles, responsibilities and new skills, and lack of a business model that incorporates telemedicine in the services portfolio to ensure its sustainability. In addition to suitable management of change and of the necessary strategic alignment, the definitive normalization of telemedicine in a mixed healthcare model based on purchasing of healthcare services using providers' contracts requires a clear and stable business model that incorporates this modality in the services portfolio and allows healthcare organizations to obtain reimbursement from the payer. 2010 SESPAS.

  7. On Variable Geometric Factor Systems for Top-Hat Electrostatic Space Plasma Analyzers

    Science.gov (United States)

    Kataria, Dhiren O.; Collinson, Glyn A.

    2010-01-01

    Even in the relatively small region of space that is the Earth's magnetosphere, ion and electron fluxes can vary by several orders of magnitude. Top-hat electrostatic analyzers currently do not possess the dynamic range required to sample plasma under all conditions. The purpose of this study was to compare, through computer simulation, three new electrostatic methods that would allow the sensitivity of a sensor to be varied through control of its geometric factor (GF) (much like an aperture on a camera). The methods studied were inner filter plates, split hemispherical analyzer (SHA) and top-cap electrode. This is the first discussion of the filter plate concept and also the first study where all three systems are studied within a common analyzer design, so that their relative merits could be fairly compared. Filter plates were found to have the important advantage that they facilitate the reduction in instrument sensitivity whilst keeping all other instrument parameters constant. However, it was discovered that filter plates have numerous disadvantages that make such a system impracticable for a top-hat electrostatic analyzer. It was found that both the top-cap electrode and SHA are promising variable geometric factor system (VGFS) concepts for implementation into a top-hat electrostatic analyzer, each with distinct advantages over the other.

  8. Alternative Labeling Programs and Purchasing Behavior toward Organic Foods: The Case of the Participatory Guarantee Systems in Brazil

    Directory of Open Access Journals (Sweden)

    Giovanna Sacchi

    2015-06-01

    Full Text Available Regulatory standards and certification models are essential tools guaranteeing the authenticity of organic products. In particular, third-party certification is useful to consumers since it provides guarantees regarding production processes and food quality. In an attempt to cope with the costs and bureaucratic procedures related to the adoption of such certification, groups of small producers have begun to rely upon alternative quality assurance systems such as Participatory Guarantee Systems (PGS. This study contextualizes and analyzes the PGS scheme and describes the Brazilian Rede Ecovida de Agroecologia network. We then investigate the effect of various factors on Brazilian consumers’ purchasing behavior for organic products guaranteed by PGS. The results show that employed and older consumers who live in rural and suburban areas are more likely to buy organic PGS products.

  12. Bridge deck repair and protective systems: latex modified concrete topping. Interim report

    Swanson, H.N.

    1984-07-01

    Measures to reduce or eliminate bridge deck deterioration by the use of various protective systems have been the subject of a series of reports begun in 1976. This report presents current observations of latex-modified deck-topping concrete protective systems. Latex-modified concrete topping has not provided long-term protection for the ten structures under evaluation in Colorado. Cost comparisons are made between repair with latex-modified concrete and deck replacement. Over a 40-year period, replacement costs are slightly less than rehabilitation costs. Greater control of the curing of deck-topping materials may reduce shrinkage cracking. Nightime paving, cooler calmer weather and higher humidity would increase the probability of success on latex-modified concrete to rehabilitation projects. Asphalt membrane and asphalt overlay are also suggested to increase the probability of success.

    2012-01-01

    New space missions will increasingly rely on more advanced technologies because of system requirements for higher performance, particularly in instruments and high-speed processing. Component-level reliability challenges with scaled CMOS in spacecraft systems from a bottom-up perspective have been presented. Fundamental Front-end and Back-end processing reliability issues with more aggressively scaled parts have been discussed. Effective thermal management from system-level to the componentlevel (top-down) is a key element in overall design of reliable systems. Thermal management in space systems must consider a wide range of issues, including thermal loading of many different components, and frequent temperature cycling of some systems. Both perspectives (top-down and bottom-up) play a large role in robust, reliable spacecraft system design.

    2005-05-10

    The Advanced Light Source (ALS) will soon be upgraded to enable top-off operations [1], in which electrons are quasi-continuously injected to produce constant stored beam current. The upgrade is structured in two phases. First, we will upgrade our injector from 1.5 GeV to 1.9 GeV to allow full energy injection and will start top-off operations. In the second phase, we will upgrade the Booster Ring (BR) with a bunch cleaning system to allow high bunch purity top-off injection. A diagnostics upgrade will be crucial for success in both phases of the top-off project, and our plan for it is described in this paper. New booster ring diagnostics will include updated beam position monitor (BPM) electronics, a tune monitoring system, and a new scraper. Two new synchrotron light monitors and a beam stop will be added to the booster-to-storage ring transfer line (BTS), and all the existing beam current monitors along the accelerator chain will be integrated into a single injection efficiency monitoring application. A dedicated bunch purity monitor will be installed in the storage ring (SR). Together, these diagnostic upgrades will enable smooth commissioning of the full energy injector and a quick transition to high quality top-off operation at the ALS.

  16. Predators exert top-down control of soybean aphid across a gradient of agricultural management systems.

    Science.gov (United States)

    Costamagna, Alejandro C; Landis, Douglas A

    2006-08-01

    The discovery of soybean aphid, Aphis glycines Matusumura, in North America in 2000 provided the opportunity to investigate the relative strength of top-down and bottom-up forces in regulating populations of this new invasive herbivore. At the Kellogg Biological Station Long Term Ecological Research site in agroecology, we contrasted A. glycines establishment and population growth under three agricultural production systems that differed markedly in disturbance and fertility regimes. Agricultural treatments consisted of a conventional-tillage high-input system, a no-tillage high-input system, and a zero-chemical-input system under conventional tillage. By selectively restricting or allowing predator access we simultaneously determined aphid response to top-down and bottom-up influences. Irrespective of predator exclusion, our agricultural manipulations did not result in bottom-up control of A. glycines intrinsic rate of increase or realized population growth. In contrast, we observed strong evidence for top-down control of A. glycines establishment and overall population growth in all production systems. Abundant predators, including Harmonia axyridis, Coccinella septempunctata, Orius insidiosus, and various predaceous fly larvae, significantly reduced A. glycines establishment and population increase in all trials. In contrast to other systems in which bottom-up forces control herbivore populations, we conclude that A. glycines is primarily controlled via top-down influences of generalist predators under a wide range of agricultural management systems. Understanding the role of top-down and bottom-up forces in this context allows agricultural managers to focus on effective strategies for control of this invasive pest.

    Full Text Available Rain water harvesting is received increased attention world wide as an alternative source of water. Roof-top rain water harvesting system is looked upon as one of the most feasible and economical ways of water conservation. With increasing problem of water scarcity, planning and designing roof top rain water harvesting is gaining wider importance to meet ever-increasing water demand, encouraging use of water or more sustainable basis. The rain water harvesting is the simple collection or storing of water for the domestic or the agriculture purpose. The method of rain water harvesting has been into practice since ancient times. The method is simple and cost effective too. Malda district of West Bengal is badly affected by Arsenic contamination in ground water. The present study finds its usefulness in developing awareness towards judicious use of water among masses and efficient ways to harvest roof top rain water resources at institutional / multistoried buildings in Malda district.

  2. Top-down control analysis of systems with more than one common intermediate.

    Science.gov (United States)

    Ainscow, E K; Brand, M D

    1995-08-01

    The analysis of the control of complex metabolic systems can be greatly simplified by application of the top-down approach of metabolic control analysis, in which the reactions of the system are grouped together into a small number of blocks connected by a common intermediate. The experimental application of the top-down approach has so far been limited to systems that have only a single intermediate. In this study, we demonstrate that the connectivity and summation theorems of metabolic control analysis hold with any number of intermediates between the metabolic blocks, and in doing so show that top-down analysis is valid for systems with multiple intermediates and so can be applied to most metabolic systems regardless of their complexity; an example of such an application is provided. Top-down control analysis has successfully described the control of mitochondrial respiration by dividing the system into three blocks, the respiratory chain, phosphorylation system and proton leak, all linked by a single intermediate, proton motive force. Here, we subdivide the respiratory chain into succinate consumers and cytochrome oxidase so that a second intermediate, cytochrome c redox state, is generated. Despite the fact that the redox state of cytochrome c is not measured, we solve the control over the system fluxes. In common with previous studies, we find that under conditions where there is no ATP turnover (state 4), respiration is largely controlled by proton leak, while at maximal ATP turnover (state 3) respiration is controlled by the respiratory chain and the phosphorylating system. In state 4,85% of the control by the respiratory chain resides with cytochrome oxidase. As ATP turnover increases, the respiration rate increases, and the control by the respiratory chain shifts from cytochrome oxidase to the succinate consumers, so that in state 3 83% of the control by the respiratory chain lies in the reactions between succinate and cytochrome c and only 17% resides

    2009-01-01

    A major problem of unstructured P2P systems is their heavy network traffic. This is caused mainly by high numbers of query answers, many of which are irrelevant for users. One solution to this problem is to use Top-k queries whereby the user can specify a limited number (k) of the most relevant answers. In this paper, we present FD, a (Fully Distributed) framework for executing Top-k queries in unstructured P2P systems, with the objective of reducing network traffic. FD consists of a family of algorithms that are simple but effec-tive. FD is completely distributed, does not depend on the existence of certain peers, and addresses the volatility of peers during query execution. We vali-dated FD through implementation over a 64-node cluster and simulation using the BRITE topology generator and SimJava. Our performance evaluation shows that FD can achieve major performance gains in terms of communication and response time.

    García, Jose L.; Elorrieta, Jose; Robredo, Jose C.; García, Ricardo; García, Fernando; Gimenez, Martin C.

    2013-04-01

    During the last fifteen years a research team from School of Forestry at the Technical University of Madrid (Spain) has developed several competitive research projects regarding forest roads and open top culverts. A first approach was established with a prototype of 7 meters length in a hydraulic channel at the laboratory determining main parameters of different open top culverts in relation to different sizes of gravels and the self washing properties relationship with different slopes up to 8 %. The curves obtained may help to properly install these drainage systems avoiding maintenance costs. In addition more targeted pilot studies were developed in different forest earth roads in center and north Spain. The construction of the stations under study was financed by the U.P.M and the R&D National Plan. The main outcomes relates the low variation of humidity in a 20 m. wide range at both sides of the open top culverts and several considerations relating the angle of installation, the spacing of such drainage systems and the benefits against rilling along the roads. Also the erosion produced downhill was established and some construction methods to avoid adverse ecological effects. The diffusion of results includes congresses and a small booklet with a great acceptance in forestry services. Also a patent (ES 2 262 437) of an advanced model has been registered.

    2014-04-01

    An innovative method for generating a flat-top pulsed magnetic field by means of capacitor banks is developed at the Wuhan National High Magnetic Field Center (WHMFC). The system consists of two capacitor banks as they are normally used to generate a pulsed field. The two discharge circuits (the magnet circuit and the auxiliary circuit) are coupled by a pulse transformer such that the electromotive force (EMF) induced via the transformer in the magnet circuit containing the magnet coil is opposed to the EMF of the capacitor bank. At a certain point before the current pulse in the coil reaches its peak, the auxiliary circuit is triggered. With optimized parameters for charging voltage and trigger delay, the current in the magnet circuit can be approximately kept constant to obtain a flat-top. A prototype was developed at the WHMFC; the magnet circuit was energized by seven 1 MJ (3.2 mF/25 kV) capacitor modules and the auxiliary circuit by four 1 MJ modules. Fields up to 41 T with 6 ms flat-top have been obtained with a conventional user magnet used at the WHMFC.

    2012-01-01

    Database management systems are today's most reliable mean to organize data into collections that can be searched and updated. However, many DBMS systems are available on the market each having their pros and cons in terms of reliability, usability, security, and performance. This paper presents a comparative study on the performance of the top DBMS systems. They are mainly MS SQL Server 2008, Oracle 11g, IBM DB2, MySQL 5.5, and MS Access 2010. The testing is aimed at executing different SQL queries with different level of complexities over the different five DBMSs under test. This would pave the way to build a head-to-head comparative evaluation that shows the average execution time, memory usage, and CPU utilization of each DBMS after completion of the test.

  12. ALS Booster Ring RF System Upgrade for Top-Off Mode of Operation

    CERN Document Server

    Kwiatkowski, Slawomir

    2005-01-01

    ALS is one of the first third generation synchrotron light sources which has been operating since 1993 at Berkeley Lab. In the present ALS operation scenario 1.5GeV electron beam is injected from the booster into the storage ring every 8 hours where is accelerated to the final energy of 1.9GeV. The beam decays between fills from 400mA to 200mA with the time average current of 250mA. In order to increase the beam brighthess ALS team plans to increase the beam current to 500mA and maintain it constant during machine operation ("Top-Off" mode of operation). This operation scenario will require full energy injection from the booster ring into the storage ring and constant operation of the injector (10 bunches with the total charge of 1nC every 30 to 35 seconds). In this paper we will present the results of the ALS injector RF system analysis fo Top-Off mode of operation and describe the way we intent to implement the necessary modifications to the booster RF system.

  15. Exploring the market for third-party-owned residential photovoltaic systems: insights from lease and power-purchase agreement contract structures and costs in California

    Science.gov (United States)

    Davidson, Carolyn; Steinberg, Daniel; Margolis, Robert

    2015-02-01

    Over the past several years, third-party-ownership (TPO) structures for residential photovoltaic (PV) systems have become the predominant ownership model in the US residential market. Under a TPO contract, the PV system host typically makes payments to the third-party owner of the system. Anecdotal evidence suggests that the total TPO contract payments made by the customer can differ significantly from payments in which the system host directly purchases the system. Furthermore, payments can vary depending on TPO contract structure. To date, a paucity of data on TPO contracts has precluded studies evaluating trends in TPO contract cost. This study relies on a sample of 1113 contracts for residential PV systems installed in 2010-2012 under the California Solar Initiative to evaluate how the timing of payments under a TPO contract impacts the ultimate cost of the system to the customer. Furthermore, we evaluate how the total cost of TPO systems to customers has changed through time, and the degree to which contract costs have tracked trends in the installed costs of a PV system. We find that the structure of the contract and the timing of the payments have financial implications for the customer: (1) power-purchase contracts, on average, cost more than leases, (2) no-money-down contracts are more costly than prepaid contracts, assuming a customer’s discount rate is lower than 17% and (3) contracts that include escalator clauses cost more, for both power-purchase agreements and leases, at most plausible discount rates. In addition, all contract costs exhibit a wide range, and do not parallel trends in installed costs over time.

  18. Characterizing the effects of feature salience and top-down attention in the early visual system.

    Science.gov (United States)

    2017-04-05

    The visual system employs a sophisticated balance of attentional mechanisms: salient stimuli are prioritized for visual processing, yet observers can also ignore such stimuli when their goals require directing attention elsewhere. A powerful determinant of visual salience is local feature contrast: if a local region differs from its immediate surround along one or more feature dimensions, it will appear more salient. Here, we used high-resolution fMRI at 7T to characterize the modulatory effects of bottom-up salience and top-down voluntary attention within multiple sites along the early visual pathway, including visual areas V1-V4 and the lateral geniculate nucleus (LGN). Observers viewed arrays of spatially distributed gratings, where one of the gratings immediately to the left or right of fixation differed from all other items in orientation or motion direction, making it salient. To investigate the effects of directed attention, observers were cued to attend to the grating to the left or right of fixation, which was either salient or non-salient. Results revealed reliable additive effects of top-down attention and stimulus-driven salience throughout visual areas V1-hV4. In comparison, the LGN exhibited significant attentional enhancement but was not reliably modulated by orientation- or motion-defined salience. Our findings indicate that top-down effects of spatial attention can influence visual processing at the earliest possible site along the visual pathway, including the LGN, while the processing of orientation- and motion-driven salience primarily involves feature-selective interactions that take place in early cortical visual areas.

  19. Supervisor localization a top-down approach to distributed control of discrete-event systems

    CERN Document Server

    Cai, Kai

    2016-01-01

    This monograph presents a systematic top-down approach to distributed control synthesis of discrete-event systems (DES). The approach is called supervisor localization; its essence is the allocation of external supervisory control action to individual component agents as their internal control strategies. The procedure is: first synthesize a monolithic supervisor, to achieve globally optimal and nonblocking controlled behavior, then decompose the monolithic supervisor into local controllers, one for each agent. The collective behavior of the resulting local controllers is identical to that achieved by the monolithic supervisor. The basic localization theory is first presented in the Ramadge–Wonham language-based supervisory control framework, then demonstrated with distributed control examples of multi-robot formations, manufacturing systems, and distributed algorithms. An architectural approach is adopted to apply localization to large-scale DES; this yields a heterarchical localization procedure, which is...

  20. Using Contextual Information as Virtual Items on Top-N Recommender Systems

    CERN Document Server

    Domingues, Marcos A; Soares, Carlos

    2011-01-01

    Traditionally, recommender systems for the Web deal with applications that have two dimensions, users and items. Based on access logs that relate these dimensions, a recommendation model can be built and used to identify a set of N items that will be of interest to a certain user. In this paper we propose a method to complement the information in the access logs with contextual information without changing the recommendation algorithm. The method consists in representing context as virtual items. We empirically test this method with two top-N recommender systems, an item-based collaborative filtering technique and association rules, on three data sets. The results show that our method is able to take advantage of the context (new dimensions) when it is informative.

    In recent years, several automated scale-down bioreactor systems have been developed to increase efficiency in cell culture process development. ambr™ is an automated workstation that provides individual monitoring and control of culture dissolved oxygen and pH in single-use, stirred-tank bioreactors at a working volume of 10-15 mL. To evaluate the ambr™ system, we compared the performance of four recombinant Chinese hamster ovary cell lines in a fed-batch process in parallel ambr™, 2-L bench-top bioreactors, and shake flasks. Cultures in ambr™ matched 2-L bioreactors in controlling the environment (temperature, dissolved oxygen, and pH) and in culture performance (growth, viability, glucose, lactate, Na(+), osmolality, titer, and product quality). However, cultures in shake flasks did not show comparable performance to the ambr™ and 2-L bioreactors.

    A new topping cycle coal power generation process is to be developed as a Japanese national project of high efficiency power generation process of coal. This process consists of a combination system of a pressurized bubbling fluidized-bed coal gasifier and a pressurized bubbling fluidized-bed combustor in series. To evaluate the performances and also to determine specifications and operation parameters of this process, it is extremely important to analyze the behavior and the performance of this system by a reasonable simulation model. A simulation model of this new process is developed in this paper. It is demonstrated by calculated results from this model that the carbon conversion in the gasifier, the composition and the heating value of produced gas are strongly dependent on operating conditions. Heat recovery by the steam in the combustor is also estimated as the function of coal feed rate.

  4. Top-level modeling of an als system utilizing object-oriented techniques

    Science.gov (United States)

    Rodriguez, L. F.; Kang, S.; Ting, K. C.

    The possible configuration of an Advanced Life Support (ALS) System capable of supporting human life for long-term space missions continues to evolve as researchers investigate potential technologies and configurations. To facilitate the decision process the development of acceptable, flexible, and dynamic mathematical computer modeling tools capable of system level analysis is desirable. Object-oriented techniques have been adopted to develop a dynamic top-level model of an ALS system.This approach has several advantages; among these, object-oriented abstractions of systems are inherently modular in architecture. Thus, models can initially be somewhat simplistic, while allowing for adjustments and improvements. In addition, by coding the model in Java, the model can be implemented via the World Wide Web, greatly encouraging the utilization of the model. Systems analysis is further enabled with the utilization of a readily available backend database containing information supporting the model. The subsystem models of the ALS system model include Crew, Biomass Production, Waste Processing and Resource Recovery, Food Processing and Nutrition, and the Interconnecting Space. Each subsystem model and an overall model have been developed. Presented here is the procedure utilized to develop the modeling tool, the vision of the modeling tool, and the current focus for each of the subsystem models.

    2014-10-01

    The price of photovoltaic (PV) systems in the United States (i.e., the cost to the system owner) has dropped precipitously in recent years, led by substantial reductions in global PV module prices. This report provides a Q4 2013 update for residential PV systems, based on an objective methodology that closely approximates the book value of a PV system. Several cases are benchmarked to represent common variation in business models, labor rates, and module choice. We estimate a weighted-average cash purchase price of $3.29/W for modeled standard-efficiency, polycrystalline-silicon residential PV systems installed in the United States. This is a 46% decline from the 2013-dollar-adjusted price reported in the Q4 2010 benchmark report. In addition, this report frames the cash purchase price in the context of key price metrics relevant to the continually evolving landscape of third-party-owned PV systems by benchmarking the minimum sustainable lease price and the fair market value of residential PV systems.

    2009-07-20

    A general model for different apertures and flat-topped laser beams based on the multi-Gaussian function is developed. The general analytical expression for the propagation of a flat-topped beam through a general double-lens system with apertures is derived using the above model. Then, the propagation characteristics of the flat-topped beam through a spatial filter are investigated by using a simplified analytical expression. Based on the Fluence beam contrast and the Fill factor, the influences of a pinhole size on the propagation of the flat-topped multi-Gaussian beam (FMGB) through the spatial filter are illustrated. An analytical expression for the propagation of the FMGB through the spatial filter with a misaligned pinhole is presented, and the influences of the pinhole offset are evaluated.

    Full Text Available In Malaysia, the car safety level has been elevated through regulations and a consumer-based approach, i.e. the New Car Assessment Program in Southeast Asian Countries (ASEAN NCAP. Nevertheless, the availability of information on consumers’ car purchasing decisions towards safety is still limited in Malaysia. Thus, this study was aimed at evaluating consumers’ purchasing decisions of their present cars and investigating their awareness of ASEAN NCAP. Self-administered questionnaires were distributed among consumers visiting different car showrooms and dealer shops. The findings suggest that safety was considered as one of the top three factors by the respondents when purchasing their present cars. Awareness of ASEAN NCAP has increased as compared to a previous study. This information is essential for policy makers, manufacturers and other stakeholders to assist in setting priorities with regard to the promotion of car safety in the country.

  10. Top/Bottom Sexual Self-labels and Empathizing-Systemizing Cognitive Styles Among Gay Men in China.

    2015-07-01

    Gay men across a variety of countries label themselves by their preferences for insertive anal intercourse or receptive anal intercourse. A "top" is defined as someone who prefers the insertive role, a "bottom" as someone who prefers the receptive role, and "versatile" as someone who has no preferences regarding anal sex role. Previous studies documented that tops showed a masculine profile and bottoms showed a feminine profile in gendered personality traits. In this study, we examined the association among sexual self-label groups and empathizing-systemizing (E-S) cognitive styles among 509 gay men across multiple cities in China. There were significant differences in systemizing among sexual self-label groups, with tops scoring higher on systemizing than bottoms and versatiles. Tops were more likely to have S > E and high E and S cognitive styles than bottoms. Bottoms were more likely to have E > S and low E and S cognitive styles than tops. There was a significant indirect effect of systemizing on sexual self-label through Self-MF. There was also a significant indirect effect of sexual self-label on systemizing through Self-MF. The findings suggest that sexual self-labels among adult gay and bisexual men may reflect more than preferences for anal sex.

    Schmidt, Taly G.; Bennett, N. Robert; Mazin, Samuel R.; Star-Lack, Josh; Solomon, Edward G.; Pelc, Norbert J.

    2005-04-01

    This work investigates the modulation transfer function (MTF) of a prototype table-top inverse-geometry volumetric CT (IGCT) system. The IGCT system has been proposed to acquire sufficient volumetric data in one circular rotation using a large-area scanned source and a narrower array of fast detectors. The source and detector arrays have the same axial, or slice, extent, thus providing sufficient volumetric coverage. A prototype system has been built using a NexRay Scanning-Beam Digital X-ray system (NexRay, Inc., Los Gatos, CA) with the C-arm gantry in the horizontal position and a stage placed between the source and detector to rotate the scanned object. The resulting system has a 16-cm in-plane field of view (FOV) and 5-cm axial FOV. Two phantoms were constructed for measuring the MTF. A 76 micron tungsten wire placed axially in a plastic frame was used to measure the in-plane MTF, and the same wire slanted at 45 degrees was used to test the isotropy of the MTF. The data were calibrated for flat-field intensity and geometric misalignment and reconstructed using a modified 3D PET algorithm. For both phantoms, slices perpendicular to the wires were reconstructed. Simulations which model the IGCT system were used to verify the MTF measurement, along with analytical predictions. The measured MTF curve was similar in shape to the predicted curve with a 10% point at 20 lp/cm compared to a predicted 18 lp/cm. Future work will also study the uniformity of the MTF across the FOV and further characterize the IGCT system.

  1. Face recognition system for set-top box-based intelligent TV.

    Science.gov (United States)

    Lee, Won Oh; Kim, Yeong Gon; Hong, Hyung Gil; Park, Kang Ryoung

    2014-11-18

    Despite the prevalence of smart TVs, many consumers continue to use conventional TVs with supplementary set-top boxes (STBs) because of the high cost of smart TVs. However, because the processing power of a STB is quite low, the smart TV functionalities that can be implemented in a STB are very limited. Because of this, negligible research has been conducted regarding face recognition for conventional TVs with supplementary STBs, even though many such studies have been conducted with smart TVs. In terms of camera sensors, previous face recognition systems have used high-resolution cameras, cameras with high magnification zoom lenses, or camera systems with panning and tilting devices that can be used for face recognition from various positions. However, these cameras and devices cannot be used in intelligent TV environments because of limitations related to size and cost, and only small, low cost web-cameras can be used. The resulting face recognition performance is degraded because of the limited resolution and quality levels of the images. Therefore, we propose a new face recognition system for intelligent TVs in order to overcome the limitations associated with low resource set-top box and low cost web-cameras. We implement the face recognition system using a software algorithm that does not require special devices or cameras. Our research has the following four novelties: first, the candidate regions in a viewer's face are detected in an image captured by a camera connected to the STB via low processing background subtraction and face color filtering; second, the detected candidate regions of face are transmitted to a server that has high processing power in order to detect face regions accurately; third, in-plane rotations of the face regions are compensated based on similarities between the left and right half sub-regions of the face regions; fourth, various poses of the viewer's face region are identified using five templates obtained during the initial user

    Full Text Available Despite the prevalence of smart TVs, many consumers continue to use conventional TVs with supplementary set-top boxes (STBs because of the high cost of smart TVs. However, because the processing power of a STB is quite low, the smart TV functionalities that can be implemented in a STB are very limited. Because of this, negligible research has been conducted regarding face recognition for conventional TVs with supplementary STBs, even though many such studies have been conducted with smart TVs. In terms of camera sensors, previous face recognition systems have used high-resolution cameras, cameras with high magnification zoom lenses, or camera systems with panning and tilting devices that can be used for face recognition from various positions. However, these cameras and devices cannot be used in intelligent TV environments because of limitations related to size and cost, and only small, low cost web-cameras can be used. The resulting face recognition performance is degraded because of the limited resolution and quality levels of the images. Therefore, we propose a new face recognition system for intelligent TVs in order to overcome the limitations associated with low resource set-top box and low cost web-cameras. We implement the face recognition system using a software algorithm that does not require special devices or cameras. Our research has the following four novelties: first, the candidate regions in a viewer’s face are detected in an image captured by a camera connected to the STB via low processing background subtraction and face color filtering; second, the detected candidate regions of face are transmitted to a server that has high processing power in order to detect face regions accurately; third, in-plane rotations of the face regions are compensated based on similarities between the left and right half sub-regions of the face regions; fourth, various poses of the viewer’s face region are identified using five templates obtained

    "Big data" has become a major force of innovation across enterprises of all sizes. New platforms with increasingly more features for managing big datasets are being announced almost on a weekly basis. Yet, there is currently a lack of any means of comparability among such platforms. While the performance of traditional database systems is well understood and measured by long-established institutions such as the Transaction Processing Performance Council (TCP), there is neither a clear definition of the performance of big data systems nor a generally agreed upon metric for comparing these systems. In this article, we describe a community-based effort for defining a big data benchmark. Over the past year, a Big Data Benchmarking Community has become established in order to fill this void. The effort focuses on defining an end-to-end application-layer benchmark for measuring the performance of big data applications, with the ability to easily adapt the benchmark specification to evolving challenges in the big data space. This article describes the efforts that have been undertaken thus far toward the definition of a BigData Top100 List. While highlighting the major technical as well as organizational challenges, through this article, we also solicit community input into this process.

    Full Text Available Understanding and managing coupled human and natural systems (CHANS is a central challenge of the 21st century, but more focus is needed to pursue the most important questions within this vast field given limited research capacity and funding. We present 40 important questions for CHANS research, identified through a two-part crowdsourcing exercise within the CHANS community. We solicited members of the International Network of Research on Coupled Human and Natural Systems (CHANS-Net to submit up to three questions that they considered transformative, receiving 540 questions from 207 respondents. After editing for clarity and consistency, we asked the network's members to each evaluate a random subset of 20 questions in importance on a scale from 1 (least important to 7 (extremely important. Questions on land use and agriculture topped the list, with a median importance ranking of 5.7, followed by questions of scale, climate change and energy, sustainability and development, adaptation and resilience, in addition to seven other categories. We identified 40 questions with a median importance of 6.0 or above, which we highlight as the current view of researchers active in the field as research questions to pursue in order to maximize impact on understanding and managing coupled human and natural systems for achieving sustainable development goals and addressing emerging global challenges.

    2013-05-01

    Piloting a rotorcraft in a Degraded Visual Environment (DVE) is a very complex task, and the evolution of the rotorcraft missions tend to augment the probability of such degraded flight conditions (increase of night flights, all-weather flights, with brownout or whiteout phenomena…). When the direct view of the external situation is degraded, the avionic system can be of great help for the crew to recover the lost visual references. TopOwl® Head Mounted Sight and Display (HMSD) system is particularly adapted to such situations, allowing the pilot to remain "eyes-out" while visualizing on a large field of view different information: a conformal enhanced image (EVS) coming from an on-board sensor, various 2D and 3D symbologies (flight, navigation, mission specific symbols), a conformal synthetic representation of the terrain (SVS), a night vision image coming from the integrated Image Intensifier Tubes, or a combination of these data, depending on the external conditions and the phase of flight, according to the pilot's choice.

    2016-04-01

    Dynesys (Dynamic Neutralization System) was designed to overcome the shortcomings of fusion. The Dynesys top loading (DTL) system is a new alternative Dynesys system that can be applied via a minimally invasive procedure. This study aimed to ascertain whether DTL is a suitable device for motion preservation and prevention of instability, and to compare the clinical and radiological outcomes between DTL and Dynesys. In this study, 12 patients were treated with Dynesys and 21 patients were treated with DTL. Back and leg pain were evaluated using the visual analog scale. The Oswestry Disability Index was used to evaluate the patients' function. Range of motion (ROM) at the operative level and for the whole lumbar spine was measured pre- and postoperatively. The length of wound, blood loss, length of hospital stay, and operation duration were also compared. All patients were followed up for 12-76 months. Scores on the visual analog scale and Oswestry Disability Index were significantly improved postoperatively. The median ROM of the whole spine and index level ROM in all patients showed 12.5% and 79.6% loss, respectively. The DTL group exhibited significantly better results in terms of blood loss, wound length, and operation duration, in addition to early ambulation. In conclusion, Dynesys and DTL are semirigid fixation systems that can significantly improve clinical symptoms and signs. Our results suggested that DTL was better than Dynesys as a result of it being a minimally invasive procedure. However, further study with large sample sizes and longer follow-up durations is required to validate the effects of these dynamic stabilizers.

    Science.gov (United States)

    Soares, D P

    1985-03-01

    A process is described for quality assurance in pharmaceutical purchasing and inventory control. A quality assurance program should ensure that quality drugs are purchased at the lowest price, drug products are available when needed, the system is managed efficiently, internal controls are provided, drug products are stored under appropriate conditions, and laws, regulations, accreditation standards, and procedures are followed. To meet these objectives, product quality, vendor performance, the department's system of internal controls, purchasing data, and storage conditions should be monitored. A checklist for evaluating purchasing and inventory practices and a sample audit form listing quality assurance criteria, standards, procedures, and recommended actions are provided. A quality assurance program for pharmaceutical purchasing and inventory control should define institution-specific criteria and standards and use these standards for continual evaluation of all aspects of the purchasing and inventory control system. Documentation of quality assurance activities should be provided for use by the purchasing department, hospital administration, and regulatory bodies.

  12. Automatic cloud top height determination using a cost-effective time-lapse camera system

    Directory of Open Access Journals (Sweden)

    H. M. Schulz

    2014-03-01

    Full Text Available A new method for the determination of cloud top heights from the footage of a time-lapse camera is presented. Contact points between cloud tops and underlying terrain are automatically detected in the camera image based on differences in the brightness, texture and movement of cloudy and non-cloudy areas. The height of the detected cloud top positions is determined by comparison with a digital elevation model projected to the view of the camera. The technique has been validated using data about the cloud immersion of a second camera as well as via visual assessment. The validation shows a high detection quality, especially regarding the requirements for the validation of satellite cloud top retrieval algorithms.

  13. Top-down models in biology: explanation and control of complex living systems above the molecular level.

    Science.gov (United States)

    Pezzulo, Giovanni; Levin, Michael

    2016-11-01

    It is widely assumed in developmental biology and bioengineering that optimal understanding and control of complex living systems follows from models of molecular events. The success of reductionism has overshadowed attempts at top-down models and control policies in biological systems. However, other fields, including physics, engineering and neuroscience, have successfully used the explanations and models at higher levels of organization, including least-action principles in physics and control-theoretic models in computational neuroscience. Exploiting the dynamic regulation of pattern formation in embryogenesis and regeneration requires new approaches to understand how cells cooperate towards large-scale anatomical goal states. Here, we argue that top-down models of pattern homeostasis serve as proof of principle for extending the current paradigm beyond emergence and molecule-level rules. We define top-down control in a biological context, discuss the examples of how cognitive neuroscience and physics exploit these strategies, and illustrate areas in which they may offer significant advantages as complements to the mainstream paradigm. By targeting system controls at multiple levels of organization and demystifying goal-directed (cybernetic) processes, top-down strategies represent a roadmap for using the deep insights of other fields for transformative advances in regenerative medicine and systems bioengineering.

    Because the drug fund occupies a big part of the hospitals' flowing fund,and there are many kinds of drugs,the drugs often appear backlog or shortage.This makes more difficult for the governors make an effective decision,so the development of decision support system for purchasing drugs has already become an urgent need.According to the requirements of some hospital's drugs procurement,the prototype system of decision support system for purchasing drugs is designed.The system uses data warehouse to organize dates,uses OOM to create model database,uses genetic algorithm to realize the model intelligent selection.The simulation results show the prediction result is accurate,which can provide valid decision support to the hospital 's drugs buyers.%由于医院药品品种多、占用医院流动资金多,管理环节多,故药品库存常会出现短缺、积压等情况,这就使管理者必须对采购药品做出有效的决策,因此采购决策支持系统的开发已成为迫切需要。针对某医院药品采购业务的需求,设计并实现了药品采购决策支持系统的原型系统。该系统采用数据仓库组织数据、采用面向对象的方法建立了模型库并将遗传算法应用于模型的智能选择。运行结果表明,预测结果比较准确,能够给医院药品采购管理提供有效的决策支持。

  19. Training set optimization and classifier performance in a top-down diabetic retinopathy screening system

    Wigdahl, J.; Agurto, C.; Murray, V.; Barriga, S.; Soliz, P.

    2013-03-01

    Diabetic retinopathy (DR) affects more than 4.4 million Americans age 40 and over. Automatic screening for DR has shown to be an efficient and cost-effective way to lower the burden on the healthcare system, by triaging diabetic patients and ensuring timely care for those presenting with DR. Several supervised algorithms have been developed to detect pathologies related to DR, but little work has been done in determining the size of the training set that optimizes an algorithm's performance. In this paper we analyze the effect of the training sample size on the performance of a top-down DR screening algorithm for different types of statistical classifiers. Results are based on partial least squares (PLS), support vector machines (SVM), k-nearest neighbor (kNN), and Naïve Bayes classifiers. Our dataset consisted of digital retinal images collected from a total of 745 cases (595 controls, 150 with DR). We varied the number of normal controls in the training set, while keeping the number of DR samples constant, and repeated the procedure 10 times using randomized training sets to avoid bias. Results show increasing performance in terms of area under the ROC curve (AUC) when the number of DR subjects in the training set increased, with similar trends for each of the classifiers. Of these, PLS and k-NN had the highest average AUC. Lower standard deviation and a flattening of the AUC curve gives evidence that there is a limit to the learning ability of the classifiers and an optimal number of cases to train on.

    Full Text Available In building companies process of product and service purchase is one of the main processes of quality management system [1]. Because ofshort time-limits of contract realization, high specialization of works, necessity of fulfillment of high quality requirements and assurance of profitable financial effects the management of purchase process becomes very important element of work of the building company. The serious problem in creating and keeping the efficient system of purchase management is special type of purchase in building companies. Particular investments are realized in different country regions, objects are built based on the individual design documentations and each building becomes independent organization unit that organize purchase necessary for investment realization.An example of the management system of purchase process in building company is described in the paper. Just In Time system is widelyused during the realization of building investment. This system is especially useful in buildings because some investments, especially inbig cities, are characterized by restriction in building site. This makes impossible storing the products. In such cases close synchronization between times of delivery and requirements of purchase schedule and schedule of building realization is very important. Criteria of supplier selection as well as the methods of choosing the supplier are also presented in the paper. Special attention is paid to necessity of valuation of the purchase efficiency and the purchase risk. Basic coefficients of purchase efficiency are also described in the paper.

  2. POCIS: a system to generate pseudo top-of-atmosphere ocean color image for sensor and system evaluation

    Lee, ZhongPing; Arnone, Robert; Vaughan, Ronnie

    2010-10-01

    It requires frequent and high-resolution measurements of biogeochemical properties of the oceans in order to obtain the status of the ecosystems and evaluate its role in modulating the climate. Because of the limited coverage and high cost, such a task could not be achieved via traditional ship surveys. Satellite sensors, because of its high revisit time and synoptic coverage, can provide key measurements to remedy the weakness of ship surveys. To ensure reliable and consistent measurements from an ocean color satellite, it not only requires the sensor be well designed and calibrated, also requires the processing software be robust for a wide range of ecosystems. All these require adequate data in order to evaluate and characterize the whole system. Such data, however, will not be available until the sensor is functioning properly in the sky. To overcome this dilemma, we developed POCIS (Pseudo Ocean Color Image Simulator), which can generate top-of-atmosphere ocean color images based on sensor specs. Such images, which can be both regional and global, can then be fed into current/future processing system to generate proxy products, thus not only help to ensure the readiness of the processing system, but also help to identify weakness and strengths of such a system before its launch, and setup the bases for eventual improvements. Details of POCIS, along with examples of proxy VIIRS image products, are presented to demonstrate its capabilities and potentials.

    2015-06-01

    Full Text Available There are number of obstacles on a challenging road to the effectiveness and business and organizational excellence. One of the most difficult ones is human (not understanding of the constant flux of change. Such is the case when it comes to development of quality management system. Will the quality be either a problem or resource of some organization depends above all on the basic standpoint towards quality that exists in the organization. Many authors underline that implementation of quality management system and obtaining ISO 9000 certificate is not an easy task, but also emphasize that its maintenance and improvement is much more difficult task. The greatest number of problems that occur during the realization of project of quality management system as well as its improvement are the result of misunderstanding of the essence of standard, that is its principles. On of these principles is Leadership too, that is the role of Top Management. Managers at the highest levels are certainly the most responsible for establishing the vision and guiding organization in all business aspects, including Quality Management and Quality Management System. This work presents results of research conducted on the top management in 204 organizations with introduced quality system. Results show views of top management about the effects of introduced quality system as well as about future steps in terms of improving the same.

    The possibility of formation for a bound state of a t quark and a lighter one is investigated using potential model predictions and heavy quark effective theory approach. Resulting estimates for the 1S-2S splitting of the energy levels are compared to the total top decay width {Gamma}{sub t}. As for the case of toponium, their conclusions show that the probability of formation for T-mesons is negligibly small due to the high top mass value.

    In this paper, a systematical and retrospective review was made on how the drug purchasing system of Chinese healthcare institutions has evolved from decentralized purchasing to centralized purchasing based on four stages as budding stage, initial stage, adjustment stage and deepening stage. In each stage, the working characteris-tics, achievements and problems have been analyzed. Targeting at the problems and challenges confronted with cur-rent drug purchasing, recommendations was made to reform and improve public hospitals’ centralized purchasing sys-tem, such as persisting centralized purchasing online at provincial level, sticking to “four favorable” principles, breaking through the mechanism of compensating medical cost with drug-selling profits, promoting coordinated inter-action reforms in healthcare insurances, distribution and pricing, strengthening comprehensive services and supervi-sion, etc.%通过文献研究等方法,系统回顾我国医疗机构药品从分散采购到集中采购经历的萌芽阶段、初创阶段、调整阶段和深化阶段,梳理分析不同发展阶段的工作特点、取得的成效、存在的问题。针对当前药品采购面临的问题和挑战,提出改革和完善公立医院药品集中采购办法,坚持以省为单位集中采购的方向,坚持“四个有利于”的基本准则,全面破除“以药补医”机制,同步推进医保、流通、价格改革联动,加强综合服务和监管。

    Full Text Available This study aimed to identify and analyze Lithuanian consumers’ attitudes and purchasing behaviour towards domestic livestock products. In order to get necessary information, Lithuanian residents were interviewed. A multi-stage stratified random sampling was used to select the respondents. This study draws on a survey of 1009 respondents. The analysis of collected data was performed using the methods of mathematical statistics. The results suggest that the vast majority of Lithuanian consumers regularly buy domestic livestock products. Among this group of respondents, the top reasons for purchasing are freshness, good taste and favourable prices. Only a small share of Lithuanian consumers rarely or never buys domestic livestock products. Among this group of respondents, the top reasons for not purchasing are unfavourable prices, short shelf-life and insufficient range of products. Domestic livestock products buyers tend to be older, higher educated and have higher level of income than non-buyers.

  3. Quantum Entanglement dependence on bifurcations and scars in non autonomous systems. The case of Quantum Kicked Top

    2007-01-01

    Properties related to entanglement in quantum systems, are known to be associated with distinct properties of the corresponding classical systems, as for example stability, integrability and chaos. This means that the detailed topology, both local and global, of the classical phase space may reveal, or influence, the entangling power of the quantum system. As it has been shown in the literature, the bifurcation points, in autonomous dynamical systems, play a crucial role for the onset of entanglement. Similarly, the existence of scars among the quantum states seems to be a factor in the dynamics of entanglement. Here we study these issues for a non-autonomous system, the Quantum Kicked Top, as a collective model of a multi-qubit system. Using the bifurcation diagram of the corresponding classical limit (the Classical Kicked Top), we analyzed the pair-wise and the bi-partite entanglement of the qubits and their relation to scars, as a function of the critical parameter of the system. We found that the pair-wis...

    1996-01-01

    Public and private purchasers can shift the focus of the health care system from managing the delivery of medical services to improving health. We report on the efforts of the Pacific Business Group on Health to include health promotion and disease prevention in its definition of health care value, to pay health plans based on their performance in providing appropriate preventive care, and to encourage employers and workers to choose health plans that excel in promoting health. This example serves as a model for other purchasing groups by combining economic incentives and systems of accountability to achieve public health goals.

    Factors involved in computerizing the purchasing and inventory control functions in hospital pharmacies are described. When initiating an automated purchasing and inventory control system, a feasibility study should first be conducted to determine the extent of automation needed to develop a cost-effective system. The design of the system will depend on the extent to which the department of materials management is involved with other hospital departments. The advantages and disadvantages of decentralized versus centralized systems are discussed, and criteria for selecting hardware and software vendors are presented. A return-on-investment analysis should be performed to validate the benefits or savings expected from implementing the new automated system. Factors to consider during implementation of the new system and future developments affecting purchasing and inventory control systems, such as bar coding, are discussed. With the current concern about rapidly rising health-care costs and the need to enhance productivity, the development and implementation of automated purchasing and inventory control systems are important strategies for institutions to pursue now.

    Full Text Available Magnetic resonant coupling systems have been in vogue for some years after it was demonstrated for mid-range power transfer in 2007. This paper proposes a prototype desk-top Witricity system for powering house-hold utility equipments. The system uses the phenomena of near-field resonance coupling achieved at 400 kHz using a transmission coil wound around rim of a table and a receiver coil wound around the base of a white-LED lit table lamp. The parasitic capacitance of coils are calculated and augmented with external capacitance to achieve resonance. Distance does not come into play in this system while the system is of great practical use for household utility equipments such as table lamps mobile phones etc.

    SAG-M RCCs were prepared in triple conventional or quadruple top/bottom bag systems and filtered at +4 degrees C using the in-line filter system Leucoflex LCR 4 Macopharma after 16-24-30 h of storage. Postfiltration WBC content was determined by Nageotte hemocytometer counting. The mean WBC content of the units prepared in conventional bag systems and filtered was higher than that of the units prepared in T/B bag systems. The best results could be obtained in T/B RCCs stored for 24 h; potassium and hemolysis levels were also improved. The Leucoflex LCR 4 in-line filter T/B system can be recommended for application in the clinical routine by virtue of the effective leukocyte elimination.

    2011-10-01

    Full Text Available Abstract Background Fusion of lumbar spine segments is a well-established therapy for many pathologies. The procedure changes the biomechanics of the spine. Initial clinical benefits may be outweighed by ensuing damage to the adjacent segments. Various surgical devices and techniques have been developed to prevent this deterioration. "Topping off" systems combine rigid fusion with a flexible pedicle screw system to prevent adjacent segment disease (ASD. To date, there is no convincing evidence that these devices provide any patient benefits. Methods/Design The study is designed as a randomized, therapy-controlled trial in a clinical care setting at a university hospital. Patients presenting to the outpatient clinic with degenerative disc disease or spondylolisthesis will be assessed against study inclusion and exclusion criteria. After randomization, the control group will undergo conventional fusion. The intervention group will undergo fusion with a supplemental flexible pedicle screw system to protect the adjacent segment ("topping off". Follow-up examination will take place immediately after treatment during hospital stay, after 6 weeks, and then after 6, 12, 24 and 36 months. Subsequently, ongoing assessments will be performed annually. Outcome measurements will include quality of life and pain assessments using questionnaires (SF-36™, ODI, COMI. In addition, clinical and radiologic ASD, work-related disability, and duration of work disability will be assessed. Inpatient and 6-month mortality, surgery-related data (e.g., intraoperative complications, blood loss, length of incision, surgical duration, postoperative complications, adverse events, and serious adverse events will be documented and monitored throughout the study. Cost-effectiveness analysis will also be provided. Discussion New hybrid systems might improve the outcome of lumbar spine fusion. To date, there is no convincing published data on effectiveness or safety of these

    Schill, A. B.; Mock, M. U.

    1993-12-01

    The OSF Distributed Computing Environment (DCE) is becoming an industry standard for open distributed computing. DCE only supports client/server-style applications based on the remote procedure call (RPC) communication model. The authors describe the design and implementation of an extended distributed object-oriented environment, DC++, on top of DCE. As opposed to RPC, it supports a uniform object model, location independent invocation of fine-grained objects, remote reference parameter passing, dynamic migration of objects between nodes, and C++ language integration. Moreover, the implementation is fully integrated with DCE, using DCE UUIDs for object identification, DCE threads for interobject concurrency, DCE RPC for remote object invocation, and the DCE Cell Directory Service (CDS) for optional retrieval of objects by name. An additional stub compiler enables automatic generation of C++-based object communication interfaces. Low-level parameter encoding is done by DCE RPC's stub generation facility using the C-based DCE interface definition language (IDL).

  6. SMEs’ Purchasing Habits

    Directory of Open Access Journals (Sweden)

    Emre S. Ozmen

    2014-05-01

    Full Text Available Although micro companies overpower the small and medium enterprise (SME segment, generalizations are often with medium size companies, and therefore, there are many unknowns, especially when it comes to its buying behavior. Conformist studies and industry practices assume SMEs to be “normative” or “conservative” buyers; however, this hypothesis is untested. This article aims to scrutinize the reality, and proposes a unified model that rejects pre-containerization in buying behavior typologies, as well as selectiveness in terms of audience type, whether it is corporate, SME, or consumer. While replacing researchers’ perceptions with the audience’s, the model yields actual knowledge that can lead to audience’s beliefs in lieu of the opposite, which is used to mislead stakeholders. The study shows that SMEs also buy like individuals and spend in a similar way to consumers’, including not only “normative” and “conservative” but also “negligent” and “impulse” zones. From the research-implications perspective, future studies by behaviorists can explore why SMEs purchase in this way. Marketers may benefit from the finding that SMEs buy like individuals. In addition, SMEs may want to be conscious of their purchasing habits, and—utilizing the newly introduced “risk score” frontier—policymakers should assess the consequences of these habits at the macro level.

  9. Relationships between thrusting and joint systems in the Jaca thrust-top basin, Spanish Pyrenees

    Science.gov (United States)

    Turner, J. P.; Hancock, P. L.

    The Oligo-Miocene rocks of the West Jaca thrust-top basin and adjacent parts of the Ebro basin are cut by up to eight sets of joints and allied mesofractures. The fractures belong to three groups that can be distinguished on the basis of their relative ages and geometry. An older group of joints strikes normal or subnormal to the Pyrenean mountain front and is restricted to subareas (here called front-normal joint domains) coincident with the immediate footwalls of thrusts. Joints striking parallel to a buried lateral ramp characterize a lateral ramp joint domain. Younger joints striking parallel or subparallel to the mountain front occur throughout most of the West Jaca and Ebro basins, and define front-parallel joint domains. The joint domains appear to reflect the geometry and evolution of thrust sheets. Joints in front-normal domains were formed during stretching of footwalls as a result of their loading by overriding thrust sheets. Stretching above a lateral ramp is thought to be responsible for the development of joints in the lateral ramp domain. Joints in the front-parallel domains of the West Jaca basin are related to stretching in growth folds that were amplifying during salt doming. Front-parallel joints in the Ebro basin are attributed to stretching of a foreland basin sequence above a basement flexure related to thrust loading.

    Gold nanoparticles can be targeted to biomarkers to give functional information on a range of tumour characteristics. X-ray fluorescence (XRF) techniques offer potential quantitative measurement of the distribution of such heavy metal nanoparticles. Biologists are developing 3D tissue engineered cellular models on the centimetre scale to optimise targeting techniques of nanoparticles to a range of tumour characteristics. Here we present a high energy bench-top K-X-ray fluorescence system designed for sensitivity to bulk measurement of gold nanoparticle concentration for intended use in such thick biological samples. Previous work has demonstrated use of a L-XRF system in measuring gold concentrations but being a low energy technique it is restricted to thin samples or superficial tumours. The presented system comprised a high purity germanium detector and filtered tungsten X-ray source, capable of quantitative measurement of gold nanoparticle concentration of thicker samples. The developed system achieved a measured detection limit of between 0.2 and 0.6 mgAu/ml, meeting specifications of biologists and being approximately one order of magnitude better than the detection limit of alternative K-XRF nanoparticle detection techniques. The scatter-corrected K-XRF signal of gold was linear with GNP concentrations down to the detection limit, thus demonstrating potential in GNP concentration quantification. The K-XRF system demonstrated between 5 and 9 times less sensitivity than a previous L-XRF bench-top system, due to a fundamental limitation of lower photoelectric interaction probabilities at higher K-edge energies. Importantly, the K-XRF technique is however less affected by overlying thickness, and so offers future potential in interrogating thick biological samples.

Also examined is the relationship between attitudinal and demographic variables and trends in intention variables. Two sets of data are analyzed. The first set was collected in the spring of 1980. The method used was an initial telephone survey followed by a mailing to each participating respondent. The mailing included information about active solar energy systems and a mail questionnaire for the respondent ot complete and return. The early study examined the homeowners' awareness of active solar energy systems, awareness of federal and state incentives for installing solar equipment, attitudes and beliefs about active solar systems, likelihood of purchasing a solar system in the short and long term, and demographics. The second set is a followup of 343 cases selected from the earlier study. (LEW)

    Full Text Available Masonry infills are normally considered as non-structural elements and their stiffness contributions are generally ignored in practice. But they affect both the structural and non-structural performance of the RC buildings during earthquakes. RC frame building with open first storey is known as soft storey, which performs poorly during strong earthquake shaking. A similar soft storey effect can also appear at top storey level if a storey used as a service storey. Hence a combination of two structural system components i.e. Rigid frames and RC shear walls leads to a highly efficient system in which shear wall resist the majority of the lateral loads and the frame supports majority of the gravity loads. To study the effect of masonry infill and different soft storey level, 11 models of R C framed building were analyzed with two types of shear wall when subjected to earthquake loading. The results of bare frame and other building models have been compared, it is observed that model with swastika and L shape shear wall with core wall are showing efficient performance and hence reducing the effect of soft storey and also reducing the effect of water pressure in the top soft storey.

    Ultrahigh-gradient electron acceleration has been confirmed owing to the laser wakefield acceleration mechanism driven by an intense short laser wakefield acceleration mechanism driven by an intense short laser pulse in an underdense plasma. The laser wakefield acceleration makes it possible to build a compact electron linac capable of producing an ultra-short bunched electron beam. While the accelerator is attributed to longitudinal wakefields, transverse wakefields simultaneously generated by a short laser pulse can serve as a plasma undulator with a very short wavelength equal to a half of the plasma wavelength. We propose a new FEL concept for X-rays based on a laser wakefield accelerator-undulator system driven by intense short laser pulses delivered from table-top terawatt lasers. The system is composed of the accelerator stage and the undulator stage in a table-top size. A low energy electron beam is accelerated an bunched into microbunches due to laser wakefields in the accelerator stage. A micro-bunched beam travelling to the opposite direction of driving laser pulses produces coherent X-ray radiation in the undulator stage. A practical configuration and its analyses are presented.

    1989-01-01

    Development of a three solar cell stack can lead to practical efficiencies greater than 30 percent (1x,AM0). A theoretical efficiency limitation of 43.7 percent at AM0 and one sun is predicted by this model. Including expected losses, a practical system efficiency of 36.8 percent is anticipated. These calculations are based on a 1.93eV/1.43eV/0.89eV energy band gap combination. AlGaAs/GaAs/GaInAsP materials can be used with a six-terminal wiring configuration. The key issues for multijunction solar cells are the top and middle solar cell performance and the sub-bandgap transparency. AstroPower has developed a technique to fabricate AlGaAs solar cells on rugged, self-supporting, transparent AlGaAs substrates. Top solar cell efficiencies greater than 11 percent AM0 have been achieved. State-of-the-art GaAs or InP devices will be used for the middle solar cell. GaInAsP will be used to fabricate the bottom solar cell. This material is lattice-matched to InP and offers a wide range of bandgaps for optimization of the three solar cell stack. Liquid phase epitaxy is being used to grow the quaternary material. Initial solar cells have shown open-circuit voltages of 462 mV for a bandgap of 0.92eV. Design rules for the multijunction three solar cell stack are discussed. The progress in the development of the self-supporting AlGaAs top solar cell and the GaInAsP bottom solar cell is presented.

    Full Text Available The accounting and auditing scandals seen in global scale have created significant scepticisms about accuracy and honesty claim on the financial reports of business managements. The fact that business administrators design internal control systems with respect to institutional management and make it to operate efficiently both increases the efficiency and productivity of activities and raises the reliability level of financial reports. When internal control system is handled within the frame of cycle approach, faults and frauds are mostly seen in the purchase and payment cycle. In this study, the determination of the risks in purchase and payment cycle, of the precautions to be taken for the risk and of the politics and procedures regarding fault and fraud have been tackled.

    Campana, S

    2010-01-01

    The ATLAS experiment at CERN developed an automated system for distribution of simulated and detector data. Such system, which partially consists of various ATLAS specific services, strongly relies on the WLCG infrastructure, both at the level of middleware components, service deployment and operations. Because of the complexity of the system and its highly distributed nature, a dedicated effort was put in place to deliver a reliable service for ATLAS data distribution, offering the necessary performance, high availability and accommodating the main use cases. This contribution will describe the various challenges and activities carried on in 2008 for the commissioning of the system, together with the experience distributing simulated data and detector data. The main commissioning activity was concentrated in two Combined Computing Resource Challenges, in February and May 2008, where it was demonstrated that the WLCG service and the ATLAS system could sustain the peak load of data transfer according to the co...

  6. Development of a SoC for Digital Television Set-Top Box: Architecture and System Integration Issues

    Directory of Open Access Journals (Sweden)

    André Borin Soares

    2013-01-01

    Full Text Available This work presents the integration of several IPs to generate a system-on-chip (SoC for digital television set-top box compliant to the SBTVD standard. Embedded consumer electronics for multimedia applications like video processing systems require large storage capacity and high bandwidth memory. Also, those systems are built from heterogeneous processing units, designed to perform specific tasks in order to maximize the overall system efficiency. A single off-chip memory is generally shared between the processing units to reduce power and save costs. The external memory access is one bottleneck when decoding high-definition video sequences in real time. In this work, a four-level memory hierarchy was designed to manage the decoded video in macroblock granularity with low latency. The use of the memory hierarchy in the system design is challenging because it impacts the system integration process and IP reuse in a collaborative design team. Practical strategies used to solve integration problems are discussed in this text. The SoC architecture was validated and is being progressively prototyped using a Xilinx Virtex-5 FPGA board.

    A novel control strategy to improve energy efficiency and to enhance passengers' thermal comfort of a new roof top bus multiple circuit air conditioning (AC) system operating on partial load conditions is presented. A novel strategy for automatic control of the AC system was developed based on numerous experimental test runs at various operating conditions, taking into account energy saving and thermal comfort without sacrificing the proper cycling rate of the system compressor. For this task, more than 50 test runs were conducted at different set point temperatures of 21, 22 and 23 C. Fanger's method was used to evaluate passenger thermal comfort, and the system energy consumption was also calculated. A performance comparison between that of the conventional AC system and that of the newly developed one has been conducted. The comparison revealed that the adopted control strategy introduces significant improvements in terms of thermal comfort and energy saving on various partial load conditions. Potential energy saving of up to 31.6% could be achieved. This results in a short payback period of 17 months. It was found from the economic analysis that the new system is able to save approximately 20.0% of the life cycle cost. (author)

    2016-12-01

    NASA's Carbon Monitoring System (CMS) began in 2010 with the goal of better understanding carbon stocks and fluxes using remote sensing observations. Models play a critical role in achieving this goal by integrating diverse observations of the carbon cycle (e.g. vegetation characteristics, ocean color, night lights, precipitation) to produce estimates of flux, which is not directly observable at a global scale. Built around NASA's Goddard Earth Observing System, version 5 (GEOS-5) atmospheric general circulation model and data assimilation system, the GEOS-Carb system supports CMS by providing data-driven, bottom-up and top-down flux estimates and high-resolution global estimates of carbon dioxide concentration. Because all modeling components use a consistent set of meteorological forcing from GEOS-5, this system provides a unique, physically consistent view of the relationship between carbon flux and climate. We will present 1) an overview of the GEOS-Carb modeling system, products, and available web tools, 2) recent results placing 2015, a record-breaking meteorological year, in the context of the 13-year GEOS-Carb record, and 3) future directions in global modeling in support of science policy and satellite mission planning.

  9. Purchasing health care in China: experiences, opportunities and challenges.

    Yip, Winnie; Hanson, Kara

    2009-01-01

    Purchasing has been promoted as a key policy instrument to improve health system performance. Despite its widespread adoption, there is little empirical evidence on how it works, the challenges surrounding its implementation, its impact, and the preconditions for it to function effectively, particularly in low- and middle-income settings. The objective of this chapter is to analyze critically the extent to which purchasing could be, and has been used strategically in China and to identify modifications that are needed for purchasing to be effective in assuring that the government's new funding for health care will result in efficient and effective health services. We present a conceptual framework for purchasing, which identifies three critical principal-agent relationships in purchasing. We draw on evidence from secondary data, results of other research studies, interviews, and the impact evaluation of a social experiment in rural China that explicitly used purchasing to improve quality and efficiency. This information is used to examine purchasing relationships in urban social health insurance (SHI), the rural medical insurance scheme, and purchasing of public health services. To date, use of strategic purchasing is limited in China. Both the urban and the rural health insurance schemes act as passive third-party payers, failing to take advantage of the opportunities to strengthen incentives to improve quality and efficiency. This may be because as government agencies, the extent to which the Ministries of Health and Labor and Social Security can act independently from provider interests, or act in the best interest of the population, is unclear. Other important challenges include ensuring adequate representation of the population's views and preferences and making better use of the leverage provided by purchasing to create appropriate provider incentives, through better integration of financing and improved coordination among purchasers.

    The U.S. healthcare system is shifting from a fee-for-service (FFS) system to a valued-based reimbursement system focused on improving the quality of healthcare. The Centers for Medicare and Medicaid Services (CMS) implemented the Physician Quality Reporting System (PQRS) as an important component of this transition. All clinicians, including physicians, nurse practitioners, or physician assistants who bill to Medicare Part B FFS, should submit quality data to the PQRS in 2015 or they will receive up to a 4% negative reimbursement penalty in 2017. As implementing and reporting PQRS measures can be a daunting task, especially for palliative care professionals, this article provides high priority tips identified by the authors for PQRS reporting in the palliative care field.

    Thermodynamic irreversibility in the flow system provides information on the energy and power losses in the system. Minimization of entropy generation in the flow system enables for the parametric optimization of the system operation. In the present study, parallel plates, in between, filled with the fluid are considered. The fluid motion resulted from the bi-vertical compression of the top plate of the parallel plates is examined. The entropy generation rate in the flow system is formulated after considering the constant movement of the top plate, constant applied load, and the combination of the constant velocity and applied load to the top plate. The optimum operating conditions related to the fluid motion in between the parallel plates is determined through the entropy analysis. It is found that the combination of the constant velocity and the constant applied load resulted in the low entropy generation rate.

    In this paper, a new structure of horizontal parallax light field 3D floating image display system was proposed. The structure consists of pico-projectors, Fresnel lens, micro-lens array and sub-lens array with freeform shape. By the functions of optical components, each light field of projectors could be controlled as a fan ray, which has high directivity in horizontal and wide scattered angle in vertical. Furthermore, according to the reverse light tracing and integral image display technique, horizontal parallax floating 3D could be demonstrated in the system. Simulated results show that the proposed 3D display structure has a good image quality and the crosstalk is also limited below 22.9%. Compared with other 3D technologies, this structure could have more benefits, including displaying real high resolution floating image, unnecessary of physical hardware on the image plane, scalability of large size system, without the noise from spinning component, and so on.

  15. Limitations to soybean photosynthesis at elevated carbon dioxide in free-air enrichment and open top chamber systems.

    Science.gov (United States)

    Bunce, James A

    2014-09-01

    It has been suggested that the stimulation of soybean photosynthesis by elevated CO2 was less in free-air carbon dioxide enrichment (FACE) systems than in open top chambers (OTC), which might explain smaller yield increases at elevated CO2 in FACE systems. However, this has not been tested using the same cultivars grown in the same location. I tested whether soybean photosynthesis at high light and elevated CO2 (ambient+180 μmol mol(-1)) was limited by electron transport (J) in FACE systems but by ribulose-bisphosphate carboxylation capacity (VCmax) in OTC. FACE systems with daytime and continuous CO2 enrichment were also compared. The results indicated that in both cultivars examined, midday photosynthesis at high light was always limited by VCmax, both in the FACE and in the OTC systems. Daytime only CO2 enrichment did not affect photosynthetic parameters or limitations, but did result in significantly smaller yields in both cultivars than continuous elevation. Photosynthesis measured at low photosynthetic photon flux density (PPFD) was not higher at elevated than at ambient CO2, because of an acclimation to elevated CO2 which was only evident at low measurement PPFDs.

  13. Imaging, scattering, and spectroscopic systems for biomedical optics: Tools for bench top and clinical applications

    Science.gov (United States)

    Cottrell, William J.

    Optical advances have had a profound impact on biology and medicine. The capabilities range from sensing biological analytes to whole animal and subcellular imaging and clinical therapies. The work presented in this thesis describes three independent and multifunctional optical systems, which explore clinical therapy at the tissue level, biological structure at the cell/organelle level, and the function of underlying fundamental cellular processes. First, we present a portable clinical instrument for delivering delta-aminolevulinic acid photodynamic therapy (ALA-PDT) while performing noninvasive spectroscopic monitoring in vivo. Using an off-surface probe, the instrument delivered the treatment beam to a user-defined field on the skin and performed reflectance and fluorescence spectroscopies at two regions within this field. The instrument was used to monitor photosensitizer fluorescence photobleaching, fluorescent photoproduct kinetics, and blood oxygen saturation during a clinical ALA-PDT trial on superficial basal cell carcinoma (sBCC). Protoporphyrin IX and photoproduct fluorescence excited by the 632.8 nm PDT treatment laser was collected between 665 and 775 nm. During a series of brief treatment interruptions at programmable time points, white-light reflectance spectra between 475 and 775 nm were acquired. Fluorescence spectra were corrected for the effects of absorption and scattering, informed by the reflectance measurements, and then decomposed into known fluorophore contributions in real time using a robust singular-value decomposition fitting routine. Reflectance spectra additionally provided information on hemoglobin oxygen saturation. We next describe the incorporation of this instrument into clinical trials at Roswell Park Cancer Institute (Buffalo, NY). In this trial we examined the effects of light irradiance on photodynamic efficiency and pain. The rate of singlet-oxygen production depends on the product of irradiance and photosensitizer and oxygen

  14. Adaptive Synchronization of Networked Euler-Lagrange Systems with Directed Switching Top ology

    GUO Hai-Bo; LI Hua-Yi; ZHONG Wei-Chao; ZHANG Shi-Jie; CAO Xi-Bin

    2014-01-01

    In this paper, the cooperative control problem of networked Euler-Lagrange systems with parametric uncertainties and unidirectional interaction is addressed under dynamically changing topology. As the communication graph evolves over time, a distributed control law via local effective interactions is designed. Adaptive techniques are used to deal with parametric uncertainties in the dynamics. With a continuous Lyapunov function, it is obtained that synchronization can still be achieved asymptotically as long as the union graph of the switching topologies has a directed spanning tree frequently enough. Extensions to disturbance rejection problems are also addressed using simple disturbance-observer or sliding mode control scheme. Illustrative examples with comparing simulation in the context of attitude synchronization of five non-identical spacecraft are further presented to show the effectiveness of the proposed cooperative control strategy.

    Iovine, John

    2011-01-01

    The International Space Station (ISS) has been on-orbit for over 10 years, and there have been numerous technical challenges along the way from design to assembly to on-orbit anomalies and repairs. The Passive Thermal Control System (PTCS) management team has been a key player in successfully dealing with these challenges. The PTCS team performs thermal analysis in support of design and verification, launch and assembly constraints, integration, sustaining engineering, failure response, and model validation. This analysis is a significant body of work and provides a unique opportunity to compile a wealth of real world engineering and analysis knowledge and the corresponding lessons-learned. The analysis lessons encompass the full life cycle of flight hardware from design to on-orbit performance and sustaining engineering. These lessons can provide significant insight for new projects and programs. Key areas to be presented include thermal model fidelity, verification methods, analysis uncertainty, and operations support.

    Based on analytic hierarchy process(AHP) theory,a vital important problem for top-layer planning and overall design of modern self-propelled gun-howitzer system,namely overall project decision-making,was analyzed.A hierarchy model was built to solve the complex and uncertain problem,and a decision-making index system was established.Then,the weights in all layers of the model were determined by simulating experts.Finally,according to the calculated results of the elements in each layer,the weights of the alternatives to the overall goal were calculated to conduct the hierarchy total decision.A decision example shows that the overall project of a self-propelled gun-howitzer A is much better than that of another self-propelled gun-howitzer B,digitalized in comprehensive efficiency,operability,system accuracy and economy,but inferior to it in the information capability,and there exists relatively larger gap between them in the information sharing index.

    Energy Technology Data Exchange (ETDEWEB)

    Moon, Chang-Seong [INFN, Pisa

    2016-06-02

    We present the most recent measurements of top quark pairs production and top quark properties in proton-antiproton collisions with center-of-mass energy of 1.96 TeV using CDF II detector at the Tevatron. The combination of top pair production cross section measurements and the direct measurement of top quark width are reported. The test of Standard Model predictions for top quark decaying into $b$-quarks, performed by measuring the ratio $R$ between the top quark branching fraction to $b$-quark and the branching fraction to any type of down quark is shown. The extraction of the CKM matrix element $|V_{tb}|$ from the ratio $R$ is discussed. We also present the latest measurements on the forward-backward asymmetry ($A_{FB}$) in top anti-top quark production. With the full CDF Run II data set, the measurements are performed in top anti-top decaying to final states that contain one or two charged leptons (electrons or muons). In addition, we combine the results of the leptonic forward-backward asymmetry in $t\\bar t$ system between the two final states. All the results show deviations from the next-to-leading order (NLO) standard model (SM) calculation.

    2016-01-01

    Nanophotonic quantum information processing systems require spatially ordered, spectrally uniform single photon sources (SPSs), integrated on-chip with co-designed light manipulating elements providing emission rate enhancement, emitted photon guidance, and lossless propagation. Towards this objective, we introduce and report on systems comprising an SPS array with each SPS surrounded by a dielectric building block (DBB) based multifunctional light manipulation unit (LMU). For the SPS array, we report triggered single photon emission at 77K from GaAs(001)/InGaAs single quantum dots (SQDs) grown selectively on top of nanomesas using the approach of substrate-encoded size-reducing epitaxy (SESRE). Systematic temperature and power dependent photoluminescence (PL), PL excitation, time-resolved PL, and emission statistics studies reveal high spectral uniformity and single photon emission at 77.4K with $g^{(2)}$(0) of 0.24 $\\pm$ 0.07. The SESRE based SPS arrays, following growth of a planarizing overlayer, are read...

    Emmanuel Ikart

    2005-11-01

    Full Text Available In recent years a number of organisations have implemented executive information systems (EIS in order to improve the performance of their executives’ jobs. Although the use of EIS is important in executives’ work, the majority of executives are unwilling to use EIS applications because of their design flaws. By using social factors, habits and facilitation condition variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on research in progress in Australia on the adoption and usage of EIS by executives. The preliminary results suggest that executives’ experiences in EIS positively relates to their experiences in computer-based information systems. The results also suggest there is a high degree of perceived usefulness, perceived ease of use as well as positive attitudes towards using EIS. Further, the results suggest that executives consider social factors in using EIS in their work. Moreover, the results suggest that facilitating conditions such as EIS development process, EIS management process and organisational environment are strongly related to the adoption and usage of EIS by executives. Finally, the results suggest a higher degree of EIS usage by middle managers than top-level managers, which an EIS was meant to support.

  9. MODELLING PURCHASING PROCESSES FROM QUALITY ASPECTS

    Directory of Open Access Journals (Sweden)

    Zora Arsovski

    2008-12-01

    Full Text Available Management has a fundamental task to identify and direct primary and specific processes within purchasing function, applying the up-to-date information infrastructure. ISO 9001:2000 defines a process as a number of interrelated or interactive activities transforming inputs and outputs, and the "process approach" as a systematic identification in management processes employed with the organization and particularly - relationships among the processes. To direct a quality management system using process approach, the organization is to determine the map of its general (basic processes. Primary processes are determined on the grounds of their interrelationship and impact on satisfying customers' needs. To make a proper choice of general business processes, it is necessary to determine the entire business flow, beginning with the customer demand up to the delivery of products or service provided. In the next step the process model is to be converted into data model which is essential for implementation of the information system enabling automation, monitoring, measuring, inspection, analysis and improvement of key purchase processes. In this paper are given methodology and some results of investigation of development of IS for purchasing process from aspects of quality.

  10. Challenges in purchasing and inventory control.

    Science.gov (United States)

    McAllister, J C

    1985-06-01

    In this concluding installment in a multipart series, issues that should be considered in the improvement of hospital pharmacy purchasing and inventory control systems are presented. Pharmacists must be aware of possible variation in bioavailability among different formulations of the same drug and evaluate new vendors critically. Hospital pharmacists and industry representatives should strive for a cooperative relationship by fostering ongoing dialogue. Pharmacists must continue to demand competitive bid prices on generically equivalent products of equal quality. Firm contact prices cannot be expected if product use estimates are unreliable. It is unethical to encourage additional price reductions on competitive products after a formal bid has been received. Institutions should limit their participation to one group purchasing organization or wholesaler for the competitive bid process. Inventory management through methods such as ABC analysis, economic-order quantities, calculated optimum reorder points, and other quantitative measurements should become commonplace. The use of data processing systems and devices can enable pharmacists to become more proficient at pharmaceutical purchasing and inventory control. The acquisition and distribution of pharmaceuticals in health-care institutions require good management to capture the opportunities in this area for pharmacy to contribute to fiscally sound health care.

  11. Table top surface plasmon resonance measurement system for efficient urea biosensing using ZnO thin film matrix

    Paliwal, Ayushi; Tomar, Monika; Gupta, Vinay

    2016-08-01

    The present report addresses the application of surface plasmon resonance (SPR) phenomenon for urea sensing. The former promises a high sensitivity, label-free detection, and real-time information by monitoring the refractive index change at the metal-dielectric interface. In the present report, a highly sensitive urea biosensor has been developed by integrating a ZnO thin film matrix with the SPR technique. Kretschmann configuration has been used to excite the surface plasmon (SP) modes at the ZnO-metal (gold) interface using an indigeneously developed table top SPR measurement setup. Urease (Urs), the urea-specific enzyme, has been immobilized on the surface of ZnO thin film by physical adsorption technique. The SPR reflectance curves were recorded for the prism/Au/ZnO/Urs system in angular interrogation mode with phosphate-buffered saline (PBS) solution as the liquid media. The SPR resonance angle is found to be shifted toward a lower angle from 49.1 to 42.0 deg with an increase in the urea concentration (0 to 300 mg/dl) in the PBS solution. The developed sensor (prism/Au/ZnO/Urs) is found to be highly sensitive [sensitivity=0.039 deg/(mg/dl) or 203 deg/RIU] with detection accuracy of 0.045deg.

    While the usual assumptions in multi-periodic inventory control problems are that the orders are placed at the beginning of each period (periodic review) or depending on the inventory level they can happen at any time (continuous review), in this article, we relax these assumptions and assume that the periods between two replenishments of the products are independent and identically distributed random variables. Furthermore, assuming that the purchasing price are triangular fuzzy variables, the quantities of the orders are of integer-type and that there are space and service level constraints, total discount are considered to purchase products and a combination of back-order and lost-sales are taken into account for the shortages. We show that the model of this problem is a fuzzy mixed-integer nonlinear programming type and in order to solve it, a hybrid meta-heuristic intelligent algorithm is proposed. At the end, a numerical example is given to demonstrate the applicability of the proposed methodology and to compare its performance with one of the existing algorithms in real world inventory control problems.

    Despite a booming economy, the number of uninsured Americans is rising. It hit nearly 42 million in 1996. Many of the uninsured work at businesses with fewer than 50 employees. Because small firms have traditionally found it difficult to provide health benefits, purchasing cooperatives have grown in scope and size across the country in recent years. By bringing small businesses together to buy insurance as a group, these organizations can help employers provide greater choice to their workers at a lower cost. However, to operate well in the insurance market, purchasing cooperatives must be well-designed and provided with adequate legal protections.

    Weak interactions break time-reversal (T) symmetry in the two-state system of neutral K mesons. We present and discuss a two-state mechanical system, a Foucault-type pendulum on a rotating table, for a full representation of K0 K0bar transitions by the pendulum motions including T violation. The pendulum moves with two different oscillation frequencies and two different magnetic dampings. Its equation of motion is identical with the differential equation for the real part of the CPT-symmetric K-meson wave function. The pendulum is able to represent microscopic CP and T violation with CPT symmetry owing to the macroscopic Coriolis force which breaks the symmetry under reversal-of-motion. Video clips of the pendulum motions are shown as supplementary material.

    1999-11-01

    The report deals with problems related to a Norwegian quota market connected to an international market regulated by the Kyoto Protocol. A national market has advantages compared to climatic gas taxes. Macro economically it will be more expensive to ratify the Protocol. The underdeveloped countries are not included in the quota market in the period 2008 to 2012 which gives their discharge intensive industry a competitive advantage. However, quotas may be imposed within a foreseeable future. International regulations are important to Norway. If many countries have systems with competitive free quotas the result would be rise in prices. As Norway probably would import relatively many quotas an international prohibition of competitive free quota systems would be advantageous to Norway even if possibilities for such systems have benefits from a national, district political viewpoint. Connections between allotment of free quotas and shutdowns and shaping of allotment criteria are studied. Free quotas allotted based on historical discharges and without additional conditions for maintaining activity would neither prevent shut downs nor give competitive advantages. The report has chapters on: 1) International negotiations after the conference in Kyoto and the success in making international laws as foundation for a functioning quota market. 2) Some essential advantages of a well functioning quota market are pointed out and their influence on production and consumption patterns including the danger of industry in countries with discharge limitations moving to underdeveloped countries without discharge obligations. 3) A brief discussion on quota trade before an international market is established. 4) Analysis of allotments of free quotas as a possible means for reducing the negative effects on Norwegian industry. 5) Conclusions. In an appendix the consequences of loosening some of the simplified conditions such as the quota price being unaltered through time is studied

    Functional understanding of the carbon cycle from the molecular to the global level is a high scientific priority requiring explanation of the relationship between fluxes at different spatial and temporal scales. We describe methods used to convert an open top chamber into both closed and open flow gas exchange systems utilized to measure such fluxes. The systems described consist of temporary modifications to an open top chamber, and are put in place for several days on one or several open top chambers. In the closed system approach, a chamber is quickly sealed for a short, predetermined time interval, the change in gas concentrations is measured, then the chamber is unsealed and ventilated. In the open flow system approach, airflow into the open top chamber is measured by trace gas injection, and the air stream concentration of CO{sub 2} and water vapor is measured before and after injection into the chamber. The closed chamber approach can resolve smaller fluxes, but causes transient increases in chamber air temperature, and has a high labor requirement. The open flow approach reduces the deviation of measuring conditions from ambient, may be semi-automated (requiring less labor), allows a more frequent sampling interval, but cannot resolve low fluxes well. Data demonstrating the capabilities of these systems show that, in open canopies of ponderosa pine, scaling fluxes from leaves to whole canopies is well approximated from summation of leaf P{sub s} rates. Flux measurements obtained from these systems can be a valuable contribution to our understanding whole system material fluxes, and challenge our understanding of ecosystem carbon budgets.

    The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronises, analyses of events containing top quarks allow to probe the properties of bare quarks and to test perturbative QCD. This talk will focus on recent precision top-quark measurements by the ATLAS Collaboration: Single top-quark and top-quark pair production cross sections including differential distributions will be presented, as well as measurements of top-quark pair production in association with a W or Z boson and measurements of top quark properties such as the spin correlation and W boson helicity in top quark pair events.

    We conducted a Web-based survey of approximately 40,000 Internet users on the purchase of over-the-counter (OTC) medications online in March 2009. The valid response rate was 97.8% and the number of responses was 39,208. The number of people who had purchased OTC medications online was 4,653 (11.9%), prescription medicines 792 (2.0%), and medical contact lenses 1,993 (5.1%). As a result of the multiple logistic regression analysis, independent variables with odds ratios (ORs) >1.5 were experience of purchasing prescription-only medicine online (OR=4.997, 95%CI=4.288-5.824), regular supplement use (OR=2.384, 95%CI=2.233-2.548), experience of purchasing colored contact lenses online (OR=2.206, 95%CI=1.632-2.983), no time to visit drugstores (OR=2.092, 95%CI=1.928-2.270), usage of Web sites of uncertain reliability (OR=1.992, 95%CI=1.857-2.137), and experience of purchasing therapeutic contact lenses online (OR=1.796, 95%CI=1.597-2.020). As some people have purchased prescription-only medicine or medical devices and had problems with drug information sources, the development of awareness of medical and pharmaceutical supplies and health and medical information literacy are key priorities to ensure safe OTC medication sales systems.

    The Telescope to Observe Planetary Systems (TOPS) is a proposed space mission to image in the visible (0.4-0.9 micron) planetary systems of nearby stars simultaneously in 16 spectral bands (resolution R~20). For the ~10 most favorable stars, it will have the sensitivity to discover 2 R_E rocky planets within habitable zones and characterize their surfaces or atmospheres through spectrophotometry. Many more massive planets and debris discs will be imaged and characterized for the first time. With a 1.2m visible telescope, the proposed mission achieves its power by exploiting the most efficient and robust coronagraphic and wavefront control techniques. The Phase-Induced Amplitude Apodization (PIAA) coronagraph used by TOPS allows planet detection at 2 lambda/d with nearly 100% throughput and preserves the telescope angular resolution. An efficient focal plane wavefront sensing scheme accurately measures wavefront aberrations which are fed back to the telescope active primary mirror. Fine wavefront control is al...

  7. Using government purchasing power to reduce equipment standby power

    Although the government sector represents only 10 to 15 percent of the economy in most countries, carefully targeted public procurement can play a significant role in market transformation through its influence on both buyers and suppliers. Government leadership in energy-efficient purchasing can set an example for other buyers, while creating opportunities for leading manufacturers and distributors to increase their sales and market share by offering energy-efficient products at competitive prices. Under proper circumstances, a highly visible government purchasing policy can have a disproportionately large influence on the market for efficient products. In the United States, President Bush signed an Executive Order in 2001 directing all federal agencies to buy products with low standby power (1 watt or less where possible). This represents a deliberate choice to use government purchasing - rather than regulations or incentives - as a market-based strategy to encourage energy savings. It also builds upon existing efforts to encourage Federal purchase of energy-efficient products (Energy Star products and others in the top 25th percentile of efficiency). This paper summarizes the Federal Energy Management Program s first 18 months of experience in implementing this Executive Order, including analysis of data on standby power, interactions with manufacturers and industry groups, and the relationship between these efforts and other federal programs concerning product labelling, testing, rating, and efficiency standards. After five years of implementing low-standby power purchasing, we estimate energy savings for federal agencies alone at about 230 GWh/year (worth US$14 million), with spillover effects on the broader market that will save all US consumers nearly 4000 GWh/year (US$300 million).

The study took place at the restaurant (R.U. of the State University of Londrina (UEL. After gathering information and relevant data and analyzing the results obtained, it was possible to verify that the follow-up system in the purchase procedure is informally used in that location, despite its importance. It could also be noticed that the university does not use the same system with the other units that integrate it. When comparing a public and a private company it is possible to conclude that the system used in a private company is more complete, as it is considered a routine procedure of the purchase department. As for the logistics system which integrates the purchase system, it was possible to verify that there are flaws in its conception and use, generating deviation and loss of resources used in the public sector. Some possible ways to solve the raised problems were pointed out, such as: the possibility of adopting the system of public concession in the same way that it is adopted in other public services in the city of LondrinaO artigo analisa a aplicabilidade do sistema de acompanhamento em compras e da logística numa organização pública.

    Full Text Available The current research aims to investigate various factors that influence consumers’ intention of buying foreign products. The data were collected by means of self-structured questionnaires from a total of 260 Bangladeshi consumers residing in the two major cities of the country, Dhaka and Chittagong. At the initial stage, statistical analyses, particularly descriptive analysis as well as exploratory factor analysis, were conducted using SPSS, after which structural equation modeling was run by using AMOS. The findings have established that brand image and quality of foreign products carry significant positive influence on purchase intention of foreign products. However, religiosity leaves a significant negative effect on the purchase intention of foreign products. Furthermore, findings have also revealed that the image of the country of origin carries a significant positive effect on brand image but ethnocentrism carries a significant negative effect on perceptions about the quality of foreign products in their purchase intention. The major contribution of the current study is that it focuses on Bangladesh, as there is a vacuum in contemporary literature on this topic in the context of Bangladeshi consumers. The findings derived from the study could facilitate marketers in the creation of effective marketing strategies and at the same time are also valuable for academicians as well as consumers at large.

  16. The role of purchasing in hospital performance.

    Preker, Alexander S; Langenbrunner, John C

    2005-01-01

    In this article the authors review the core messages on getting value for public money spent on healthcare presented in a recent World Bank publication, Spending Wisely: Buying Health Services for the Poor, edited by the same authors. The authors discuss how interest of the poor would often be better served through a fundamental shift in the way public money is spent on the health services--notably by moving away from passive budgeting within the public sector towards strategic purchasing or contracting of services from non-governmental providers. The shift from hiring staff in the public sector and producing services "in house" to strategic purchasing of non governmental providers--outsourcing--has been at the centre of a lively debate on collective financing of healthcare during recent years. Its underlying premise is that it is necessary to separate the functions of financing from the production services to improve performance and accountability. Promoting good health and confronting disease challenges of course requires action across a broad range of activities in the health system. This includes improvements in the policymaking and stewardship role of governments, better access to human resources, drugs, medical equipment and consumables, and a greater engagement of both public and private providers of services. Managing scarce resources and healthcare effectively and efficiently in the hospital sector through more strategic purchasing is an important part of this story. This is the second in series of articles on the economics of hospital care. In the first article on the "Economics of organizational reform" the authors, Alexander S. Preker and April Harding, examined the role of economic incentives to good governance and performance in the hospital sector. A more detailed discussion on this topic can be found in the World Bank publication Innovations in Health Care: The Corporatization of Public Hospitals, 2003, edited by the same authors.

    With the development of the Internet and E-commerce, enterprises can achieve global device purchasing with a good cost performance. But the credit risk is the key factor in selecting a device provider. Credit risk involves many qualitative and quantitative factors. We construct a multi-agent credit rating model system based on CSCW, which organically combines the people's aptitude and the capability of machines. Enterprises can use this credit rating system for forecasting and defeating the credit risk of global device purchasing.

    2017-01-01

    The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronizes, this gives us the unique opportunity to probe the properties of bare quarks at the Large Hadron Collider. This talk will present highlights of a few recent precision measurements by the ATLAS Collaboration of the top quark using 13 TeV and 8 TeV collision data: top-quark pair and single top production cross sections including differential distributions will be presented alongside top quark properties measurements. These measurements, including results using boosted top quarks, probe our understanding of top quark production in the TeV regime. Measurements of the top quark mass and searches for rare top quark decays are also presented.

    Since the top quark was discovered at Tevatron in 1995, many top quark properties have been measured. However, the top quark is still interesting due to unique features which originate from the extremely heavy mass, and providing various test grounds on the Standard Model as well as searches for a new physics. Though the measurements of the top quark had been performed only at Tevatron so far, LHC is now ready for measurements with more top quarks than Tevatron. In this article, recent measurements of top quark properties from Tevatron (CDF and DØ) as well as LHC (ATLAS and CMS) are presented.

    The top quark, when it was finally discovered at Fermilab in 1995 completed the three-generation structure of the Standard Model (SM) and opened up the new field of top quark physics. Viewed as just another SM quark, the top quark appears to be a rather uninteresting species. Produced predominantly, in hadron-hadron collisions, through strong interactions, it decays rapidly without forming hadrons, and almost exclusively through the single mode t {r_arrow} Wb. The relevant CKM coupling V{sub tb} is already determined by the (three-generation) unitarity of the CKM matrix. Rare decays and CP violation are unmeasurable small in the SM. Yet the top quark is distinguished by its large mass, about 35 times larger than the mass of the next heavy quark, and intriguingly close to the scale of electroweak (EW) symmetry breaking. This unique property raises a number of interesting questions. Is the top quark mass generated by the Higgs mechanism as the SM predicts and is its mass related to the top-Higgs-Yukawa coupling? Or does it play an even more fundamental role in the EW symmetry breaking mechanism? If there are new particles lighter than the top quark, does the top quark decay into them? Could non-SM physics first manifest itself in non-standard couplings of the top quark which show up as anomalies in top quark production and decays? Top quark physics tries to answer these questions. Several properties of the top quark have already been examined at the Tevatron. These include studies of the kinematical properties of top production, the measurements of the top mass, of the top production cross-section, the reconstruction of t{bar t}pairs in the fully hadronic final states, the study of {tau} decays of the top quark, the reconstruction of hadronic decays of the W boson from top decays, the search for flavor changing neutral current decays, the measurement of the W helicity in top decays, and bounds on t{bar t} spin correlations. Most of these measurements are limited by

    2013-11-01

    Changes in the food system are associated with the increase in consumption of foods with low nutritional value in recent decades. Data on food purchasing for household consumption, collected from the Instituto Brasileiro de Geografia e Estatística (IBGE--Brazilian Institute of Geography and Statistics) Household Budget Survey (HBS) in 2002-3, were used to describe the contribution of food purchasing sites (FPS) to the diet of Brazilian families. All the 241 distinct FPS mentioned in the HBS were grouped into ten categories, according to the nature of the products available. Food acquisitions were organized into seven groups. Supermarkets and hypermarkets accounted for 49% of the acquisitions and were the main source of six out of the seven food groups. Street markets and greengroceries stood out in the acquisitions of fruits and vegetables, accounting for 39% of this market. The large contribution of supermarkets and hypermarkets to the diet shows the need for healthy eating promotion policies aiming at these locations. Street markets and greengroceries represent important allies for healthy eating. Copyright © 2013 Elsevier Ltd. All rights reserved.

    HIPCs, or health care purchasing cooperatives, are attracting widespread interest as a key element of the managed competition approach to health reform. HIPCs perform several useful roles for individuals and small employers unable to obtain health insurance coverage in the current system by spreading risk more evenly and purchasing coverage in a given region or market area. While HIPCs are generally associated with managed competition, they are also compatible with reform strategies that require employers to pay for coverage or those that provide incentives for expanded coverage.

    Initiatives to reduce sodium in packaged foods have been launched in the United States, yet corresponding changes in the amount of sodium that US households obtain from packaged foods have not been evaluated, to our knowledge. To assess 15-year changes in the amount of sodium that US households acquire from packaged food purchases, the sodium content of purchases, and the proportion of households that have purchases with optimal sodium density. Longitudinal study of US households in the 2000 to 2014 Nielsen Homescan Consumer Panel, a population-based sample of households that used barcode scanners to record all packaged foods purchased throughout the year. Time-varying brand- and product-specific nutrition information was used for 1 490 141 products. Sociodemographic-adjusted changes in mean sodium per capita (mg/d) and sodium content (mg/100 g), overall and for top food group sources of sodium, and the proportion of households that have total purchases with sodium density of 1.1 mg/kcal or less. In a nationwide sample of 172 042 US households (754 608 year-level observations), the amount of sodium that households acquired from packaged food and beverage purchases decreased significantly between 2000 and 2014 by 396 mg/d (95% CI, -407 to -385 mg/d) per capita. The sodium content of households' packaged food purchases decreased significantly during this 15-year period by 49 mg/100 g (95% CI, -50 to -48 mg/100 g), a 12.0% decline; decreases began in 2005 and continued through 2014. Moreover, the sodium content of households' purchases decreased significantly for all top food sources of sodium between 2000 and 2014, including declines of more than 100 mg/100 g for condiments, sauces, and dips (-114 mg/100 g; 95% CI, -117 to -111 mg/100 g) and salty snacks (-142 mg/100 g; 95% CI, -144 to -141 mg/100 g). However, in all years, less than 2% of US households had packaged food and beverage purchases with sodium density of 1.1 mg/kcal or less. In this nationwide

    A vertical ship lift under earthquake excitation may suffer from a whipping effect due to the sudden change of building lateral stiffness at the top of the ship lift towers. This paper proposes a roof magnetorheological (MR) intelligent isolation system to prevent the seismic whipping effect on machinery structures. Theoretically, the dynamic models of MR damper and the mechanical model of ship lift was established, the inverse neural network controlling algorithm was proposed and the fundamental semi-active control equation for the Three-Gorges ship lift where the MR intelligent isolation system was installed was deduced. Experimentally, the experimental model of the ship lift was given, the vibrating table experiment of the MR intelligent isolation system controlling the whipping effect was carried out and the results of the inverse neural network control strategy and passive isolation strategy were compared. In practical aspect, the large-scale MR damper (500kN) and a sliding support with limited stiffness were designed and fabricated. It was proven that the MR intelligent isolation system with proper control strategy can greatly reduce the seismic whipping effect on the top workshop of the ship lift and be simple and effective enough to be applied to real engineering structures.

    Full Text Available The volume of corporate social responsibility (CSR activities is increasing worldwide; the European Union considers CSR to be one of the ways to achieve the most competitive economy and CSR awareness is also rising among companies in the Czech Republic, their customers, and the public. Bearing this in mind, Fairtrade goods, a subset of CSR and sustainable development, is an attractive step for vendors to take towards their customers. In this paper, we try to learn who the buyers of Fairtrade products are and what their motivation is in order to help Fairtrade dealers know their target group better, while at the same time helping expand this target group for organizations such as Fairtrade Czech Republic. We utilize an empirical survey and employ both univariate and bivariate statistical analyses (descriptives, associations, correlations for this purpose. While some previous findings were confirmed, such as (the influence of age and education on Fairtrade purchasing behavior, moral principles and quality of the product being stated as the most important motives to buy Fairtrade products, the significance of the Fairtrade logo and certificate for the buyers’ awareness one was disproved. According to the gathered data, the economic situation of a household does not affect Fairtrade purchasing behavior.

    Recent U.S. government regulations incentivize implementation of an electronic health record (EHR) with computerized order entry and structured results display. Many institutions have also chosen to interface their EHR to their laboratory information system (LIS). Reported long-term benefits include increased efficiency and improved quality and safety. In order to successfully implement an interfaced EHR-LIS, institutions must plan years in advance and anticipate the impact of an integrated system. It can be challenging to fully understand the technical, workflow and resource aspects and adequately prepare for a potentially protracted system implementation and the subsequent stabilization. We describe the top ten challenges that we encountered in our clinical laboratories following the implementation of an interfaced EHR-LIS and offer suggestions on how to overcome these challenges. This study was performed at a 777-bed, tertiary care center which recently implemented an interfaced EHR-LIS. Challenges were recorded during EHR-LIS implementation and stabilization and the authors describe the top ten. Our top ten challenges were selection and harmonization of test codes, detailed training for providers on test ordering, communication with EHR provider champions during the build process, fluid orders and collections, supporting specialized workflows, sufficient reports and metrics, increased volume of inpatient venipunctures, adequate resources during stabilization, unanticipated changes to laboratory workflow and ordering specimens for anatomic pathology. A few suggestions to overcome these challenges include regular meetings with clinical champions, advanced considerations of reports and metrics that will be needed, adequate training of laboratory staff on new workflows in the EHR and defining all tests including anatomic pathology in the LIS. EHR-LIS implementations have many challenges requiring institutions to adapt and develop new infrastructures. This article

    2003-01-01

    During the last few years, and more particularly to face the LHC construction, several Information Technology activities of the ST Division have been outsourced. This concerns various domains such as desktop support, application software development, system maintenance as well as turn-key control systems. Among other motivations, this tactical approach was seen as a way to achieve higher product quality and service rationalization. The outsourcing success of IT activities resides in the mastering of a complex process that includes amongst other specification, purchasing, negotiation, contract management skills on top of advanced technical knowledge. The perception of the success of outsourcing differs also from one stakeholder to another. Nowadays, as CERN encounters a cash-flow issue, in-sourcing is investigated as an alternative path for savings. From this experience and the survey of current practice in industry, this paper analyses various parameters that should be considered to find the correct balance b...

    2014-01-01

    Objective This study investigated the associations of nutrition concerns, demographics, universalism (community oriented) values, perceived control over personal health and food buying, and perceived influence over the food system with intentions to purchase low fat, sugar and salt (LFSS) food products. Methods A national online survey of 2204 Australian consumers administered in November 2011. Structural equation modeling was used to examine associations of LFSS purchasing intentions with demographic, values, perceived control, and influence factors. Results Nutrition concern, perceived influence over the food system, and universalism values were key predictors of LFSS purchasing intentions. Almost two thirds (64.6%) of the variance associated with LFSS purchasing was explained by the structural equation model. Conclusion Communication programs which focus on universalism values, nutrition concern and perceived influence over the food system are likely to increase LFSS purchasing and perhaps reduce the demand for energy dense, nutrient poor foods.

    Full Text Available Employing structural equation modeling and an extended theory of planned behaviour (TPB incorporating the additional influence of price perception as a conceptual framework, this paper explored the determinants of sunscreen purchase intention for young Moroccan adults. Consistent with the TPB, results confirmed the importance of subjective norms, attitude and perceived control in shaping sunscreen purchase intention. However, contrary to assumptions price was not found to be a significant factor in sunscreen purchase intention. Results of this study support the application of the TPB in the sunscreen purchase context and highlight the importance of using its constructs over price in the development of effective marketing campaigns.

Only higher education libraries show a well developed regional infrastructure of purchasing consortia covering virtually all eligible libraries. While there are clear sectoral disparities amongst the library purchasing consortia surveyed, the size of consortium expenditure seems to determine whether procurement professionals are involved. Thus in those whose spend consistently exceeds European Commission guidelines’ thresholds, the involvement of purchasing professionals is much more likely, and also crucial to the successful navigation of such procedures.

  16. Top quark physics

    2005-10-01

    While the top quark was discovered in 1995 at the Fermilab Tevatron, a decade later they still have very little information about the top. As the heaviest particle yet discovered, the top quark is interesting in and of itself, but some speculate that it may play a special role in physics beyond the Standard Model. With Run 2 of the Tevatron well underway, they have the opportunity to study top quark properties with much better sensitivity, and to test whether top quarks behave as predicted by current theories. This article focuses on the basics of top quark physics at the Tevatron, highlighting only a sample of the many recent measurements, as new results are being released monthly, and constantly changing the landscape of our knowledge of top.

    Value-based purchasing by employers has often been portrayed as the lynchpin to quality improvement in a market-based health care system. Although a small group of the largest national employers has been actively engaged in promoting quality measurement, reporting, and pay for performance, it is unknown whether these ideas have significantly permeated employer-sponsored health benefit purchasing. To provide systematic descriptions and analyses of value-based purchasing and related efforts to improve quality of care by health care purchasers. We conducted telephone interviews with executives at 609 of the largest employers across 41 US markets between July 2005 and March 2006. The 41 randomly selected markets have at least 100,000 persons enrolled in health maintenance organizations, include approximately 91% of individuals enrolled in health maintenance organizations nationally, and represent roughly 78% of the US metropolitan population. Using the Dun & Bradstreet database of US employers, we identified the 26 largest firms in each market. Firms ranged in size from 60 to 250,000 employees. The degree to which value-based purchasing and related strategies are reported being used by employers. Percentages were weighted by number of employees. Of 1041 companies contacted, 609 employer representatives completed the survey (response rate, 64%). A large percentage of surveyed executives reported that they examine health plan quality data (269 respondents; 65% [95% confidence interval {CI}, 57%-74%]; Prewards (49 respondents; 17% [95% CI, 7%-27%]; P=.008) or to influence employees (71 respondents; 23% [95% CI, 13%-33%]). Physician quality information is even less commonly examined (71 respondents; 16% [95% CI, 9%-23%]) or used by employers to reward performance (8 respondents; 2% [95% CI, 0%-3%]) or influence employee choice of providers (34 respondents; 8% [95% CI, 3%-12%]). Surveyed employers as a whole do not appear to be individually implementing incentives and

    Consumer support for pro environmental food policies and food purchasing are important for the adoption of successful environmental policies. This paper examines consumers' views of food policy options as their predisposition to purchase pro environmental foods along with their likely demographic, educational and cognitive antecedents including food and environmental concerns and universalism values (relating to care for others and the environment). An online survey to assess these constructs was conducted among 2204 Australian adults in November 2011. The findings showed strong levels of support for both environmental food policies (50%-78% support) and pro environmental food purchasing (51%-69% intending to purchase pro environmental foods). Confirmatory factor analysis and structural equation modelling showed that different cognitive mediators exist along pathways between demographics and the two outcome variables. Support for food policy was positively related to food and environment concerns (std. Beta = 0.25), universalism (0.41), perceived control (0.07), and regulatory issues (0.64 but negatively with food security issues (-0.37). Environment purchasing intentions were positively linked to food and nutrition concerns (0.13), food and environment concerns (0.24), food safety concerns (0.19), food and animal welfare concerns (0.16), universalism (0.25), female gender (0.05), education (0.04), and perceived influence over the food system (0.17). In addition, health study in years 11 and 12 was positively related to the beginning of both of these pathways (0.07 for each). The results are discussed in relation to the opportunities that communications based on the mediating variables offer for the promotion of environmental food policies and purchasing.

  5. Remote Sensing Image Analysis Without Expert Knowledge - A Web-Based Classification Tool On Top of Taverna Workflow Management System

    2016-10-01

    Providing software solutions via internet has been known for quite some time and is now an increasing trend marketed as "software as a service". A lot of business units accept the new methods and streamlined IT strategies by offering web-based infrastructures for external software usage - but geospatial applications featuring very specialized services or functionalities on demand are still rare. Originally applied in desktop environments, the ILMSimage tool for remote sensing image analysis and classification was modified in its communicating structures and enabled for running on a high-power server and benefiting from Tavema software. On top, a GIS-like and web-based user interface guides the user through the different steps in ILMSimage. ILMSimage combines object oriented image segmentation with pattern recognition features. Basic image elements form a construction set to model for large image objects with diverse and complex appearance. There is no need for the user to set up detailed object definitions. Training is done by delineating one or more typical examples (templates) of the desired object using a simple vector polygon. The template can be large and does not need to be homogeneous. The template is completely independent from the segmentation. The object definition is done completely by the software.

  6. Explaining Counterfeit Alcohol Purchases in Russia.

    Kotelnikova, Zoya

    2017-04-01

    Alcohol is a common target of counterfeiting in Russia. Counterfeit alcohol is defined here as the manufacture, distribution, unauthorized placement (forgery) of protected commodity trademarks, and infringement of the exclusive rights of the registered trademark holders of alcoholic beverages. It is often argued that the expansion of the counterfeit product market is due to the steady demand of economically disadvantaged people for low-priced goods. The situation becomes more complicated once deceptive and nondeceptive forms of counterfeiting are taken into account. This study aimed to identify markers of risky behavior associated with the purchase of counterfeit alcohol in Russia. The analysis relied on consumer self-reports of alcohol use and purchase collected nationwide by the Russia Longitudinal Monitoring Survey (RLMS-HSE) in 2012 to 2014. I used a generalized linear mixed-model logistic regression to identify predictors of risky behavior by consumers who purchased counterfeit alcohol, either knowingly or unknowingly, during the 30 days preceding the survey. Purchases of counterfeit alcohol declined slightly from 2012 to 2014, mainly due to a decrease in consumers mistakenly purchasing counterfeit products. Predictors of counterfeit alcohol purchases differed between consumers who knowingly and unknowingly purchased counterfeit products. Nondeceptive purchase of counterfeit alcohol was related primarily to an indifference to alcohol brands. Consumers with social networks that include drinkers of nonbeverage alcohol and producers of homemade alcohol were highly likely to consume counterfeit alcohol deliberately. Problem drinking was significantly associated with a higher risk of both deceptive and nondeceptive purchases of counterfeit alcohol. Poverty largely contributed to nondeceptive counterfeiting. The literature has overestimated the impact of low prices on counterfeit alcohol consumption. Problem drinking and membership in social networks of consumers

    In order to reduce the stochastic volatility of supply and demand, and maintain the electric power system's stability after large scale stochastic renewable energy sources connected to grid, the development and consumption should be promoted by marketing means. Bilateral contract transaction model of large users' direct power purchase conforms to the actual situation of our country. Trading pattern of large users' direct power purchase is analyzed in this paper, characteristics of each power generation are summed up, and centralized matching mode is mainly introduced. Through the establishment of power generation enterprises' priority evaluation index system and the analysis of power generation enterprises' priority based on fuzzy clustering, the sorting method of power generation enterprises' priority in trading patterns of large users' direct power purchase is put forward. Suggestions for trading mechanism of large users' direct power purchase are offered by this method, which is good for expand the promotion of large users' direct power purchase further.

  10. A validation of carbon fiber imaging couch top modeling in two radiation therapy treatment planning systems: Philips Pinnacle3 and BrainLAB iPlan RT Dose

    Full Text Available Abstract Background Carbon fiber (CF is now the material of choice for radiation therapy couch tops. Initial designs included side metal bars for rigidity; however, with the advent of IGRT, involving on board imaging, new thicker CF couch tops without metal bars have been developed. The new design allows for excellent imaging at the expense of potentially unacceptable dose attenuation and perturbation. Objectives We set out to model the BrainLAB imaging couch top (ICT in Philips Pinnacle3 treatment planning system (TPS, to validate the already modeled ICT in BrainLAB iPlan RT Dose treatment planning system and to compute the magnitude of the loss in skin sparing. Results Using CF density of 0.55 g/cm3 and foam density of 0.03 g/cm3, we demonstrated an excellent agreement between measured dose and Pinnacle3 TPS computed dose using 6 MV beam. The agreement was within 1% for all gantry angle measured except for 120o, which was 1.8%. The measured and iPlan RT Dose TPS computed dose agreed to within 1% for all gantry angles and field sizes measured except for 100o where the agreement was 1.4% for 10 cm × 10 cm field size. Predicted attenuation through the couch by iPlan RT Dose TPS (3.4% - 9.5% and Pinnacle3 TPS (2% - 6.6% were within the same magnitude and similar to previously reported in the literature. Pinnacle3 TPS estimated an 8% to 20% increase in skin dose with increase in field size. With the introduction of the CF couch top, it estimated an increase in skin dose by approximately 46 - 90%. The clinical impact of omitting the couch in treatment planning will be dependent on the beam arrangement, the percentage of the beams intersecting the couch and their angles of incidence. Conclusion We have successfully modeled the ICT in Pinnacle3 TPS and validated the modeled ICT in iPlan RT Dose. It is recommended that the ICT be included in treatment planning for all treatments that involve posteriors beams. There is a significant

  11. The stop on top

    CERN Document Server

    Zakareishvili, Tamar

    2016-01-01

    Supersymmetric partners of the top quark have been sought since the top quark has been discovered at the Tevatron. The searches are more easily performed in scenarios where the mass splitting between the top and the stop is large and where differences in kinematics are striking. The region in which top and stop are almost degenerate in mass is more difficult to explore experimentally as the final state kinematics are very similar, apart from angular-related distributions which reflect the spin/parity difference between the two particles. Usually the searches are performed looking for deviations on the measured top-quark pair production cross section with respect to the standard model prediction, or looking to simple variables such as the difference in the azimuthal angle between two leptons produced after top quark decays.

    Full Text Available Purpose - The purpose of this paper is to ask one question. How the implementation of the requirements of ISO 9001 system affects the costs of running the business? Design/methodology/approach - The research covered time from 2006 to 2011 and was an attempt to assess the impact of the maintenance of the ISO 9001 Quality Management System on the costs of small and medium sized business organizations. The main objective was the selection of right research subjects that would allow the formulation of the most reliable and statistically valid conclusions. For this purpose we obtained permissions to conduct research in organizations characterized by comparable futures such as size, industry, type of business and strategy. Findings - The study shows that the costs associated with the implementation and maintenance of the Quality Management System standard is still too high, and effectively discourages representatives of small and medium-sized commercial organizations from implementing ISO 9001 system.

  19. Identifying the computational requirements of an integrated top-down-bottom-up model for overt visual attention within an active vision system.

    Sebastian McBride

    Full Text Available Computational visual attention systems have been constructed in order for robots and other devices to detect and locate regions of interest in their visual world. Such systems often attempt to take account of what is known of the human visual system and employ concepts, such as 'active vision', to gain various perceived advantages. However, despite the potential for gaining insights from such experiments, the computational requirements for visual attention processing are often not clearly presented from a biological perspective. This was the primary objective of this study, attained through two specific phases of investigation: 1 conceptual modeling of a top-down-bottom-up framework through critical analysis of the psychophysical and neurophysiological literature, 2 implementation and validation of the model into robotic hardware (as a representative of an active vision system. Seven computational requirements were identified: 1 transformation of retinotopic to egocentric mappings, 2 spatial memory for the purposes of medium-term inhibition of return, 3 synchronization of 'where' and 'what' information from the two visual streams, 4 convergence of top-down and bottom-up information to a centralized point of information processing, 5 a threshold function to elicit saccade action, 6 a function to represent task relevance as a ratio of excitation and inhibition, and 7 derivation of excitation and inhibition values from object-associated feature classes. The model provides further insight into the nature of data representation and transfer between brain regions associated with the vertebrate 'active' visual attention system. In particular, the model lends strong support to the functional role of the lateral intraparietal region of the brain as a primary area of information consolidation that directs putative action through the use of a 'priority map'.

    We introduce a deconstructed model that incorporates both Higgsless and top-color mechanisms. The model alleviates the typical tension in Higgsless models between obtaining the correct top quark mass and keeping Δρ small. It does so by singling out the top quark mass generation as arising from a Yukawa coupling to an effective top-Higgs which develops a small vacuum expectation value, while electroweak symmetry breaking results largely from a Higgsless mechanism. As a result, the heavy partners of the SM fermions can be light enough to be seen at the LHC.

    2006-01-01

    Ten years after its discovery at the Tevatron collider, we still know little about the top quark. Its large mass suggests it may play a key role in the mechanism of Electroweak Symmetry Breaking (EWSB), or open a window of sensitivity to new physics related to EWSB and preferentially coupled to it. To determine whether this is the case, precision measurements of top quark properties are necessary. The high statistics samples being collected by the Tevatron experiments during Run II start to incisively probe the top quark sector. This report summarizes the experimental status of the top quark, focusing in particular on the recent measurements from the Tevatron Run II.

    2009-06-01

    Community-based substance abuse treatment for offenders has been shown to reduce both substance use and recidivism. One strategy to ensure treatment availability for offenders is to have each state's Department of Corrections (DOC) fund treatment directly. Purchasing treatment implies regulation, but DOC as both a purchaser and regulator of community-based services has been underexamined. This national survey of administrators from the Single State Authority (SSA) and DOC in each state found DOCs purchase treatment in 35 states, with most states purchasing it directly from community-based providers utilizing a variety of funding sources. Fewer states reported DOCs purchased ancillary services than SSAs (68% vs. 81%). Although both DOCs and SSAs had workforce and program requirements, there were differences within and between states.

    Observing systems simulation experiments (OSSE's) provide a powerful tool to assess the impact of proposed satellite borne observing systems on meteorological applications models. We describe the results of an OSSE conducted to assess the impact of data from a low power lidar wind sensor on the forecast accuracy of a global spectral numerical weather prediction (NWP) model, the Air Force Geophysics Laboratory Global Data Assimilation System. The instrument would be operating at near-infrared wavelengths thereby increasing the backscatter signal relative to comparable infrared lidar.

    The objective of this study was to evaluate the performance and to estimate costs of a wood chipping system for tree tops, which are considered residuals from wood harvesting, to be used for energy. The study was developed in a forest industry in the Para State, located in the north region of Brazil. The system was comprised by one wood chipper, two forwarders and one front loader. Data collection was based on time study, fuel consumption and chips load weighting. System average productivity was 17.51 tonnes per effective hour. Machine utilization rate was 51.9% due to many delays, mainly for repair and maintenance of the chipper. Chips transportation was considered to be the critical point of the system, due to some lack of trucks available for blowing chips. The system can produce between 94 and 162 times more energy than the energy consumed. System cost per effective hour was R$ 376.56, which means R$ 21.51/tonne of chips or R$ 2.70/G J. (author)

  18. Top Quark Mass

    CERN Document Server

    Mulders, Martijn

    2016-01-01

    Ever since the discovery of the top quark at the Tevatron collider in 1995 the measurement of its mass has been a high priority. As one of the fundamental parameters of the Standard Theory of particle physics, the precise value of the top quark mass together with other inputs provides a test for the self-consistency of the theory, and has consequences for the stability of the Higgs field that permeates the Universe. In this review I will briefly summarize the experimental techniques used at the Tevatron and the LHC experiments throughout the years to measure the top quark mass with ever improving accuracy, and highlight the recent progress in combining all measurements in a single world average combination. As experimental measurements became more precise, the question of their theoretical interpretation has become important. The difficulty of relating the measured quantity to the fundamental top mass parameter has inspired alternative measurement methods that extract the top mass in complementary ways. I wil...

    We report on top physics results using a 100 pb{sup -1} data sample of p{bar p} collisions at {radical}s = 1.8 TeV collected with the Collider Detector at Fermilab (CDF). We have identified top signals in a variety of decay channels, and used these channels to extract a measurement of the top mass and production cross section. A subset of the data (67 pb{sup -1}) is used to determine M{sub top} = 176 {+-} 8(stat) {+-} 10(syst) and {sigma}(tt) = 7.6 {sub -2.0}{sup +2.4} pb. We present studies of the kinematics of t{bar t} events and extract the first direct measurement of V{sub tb}. Finally, we indicate prospects for future study of top physics at the Tevatron.

  20. CONSUMERS’ PURCHASE INTENTIONS TOWARDS NATURAL COSMETICS

    Directory of Open Access Journals (Sweden)

    Full Text Available The purpose of this paper is to determine which variables influence consumers’ intentions towards purchasing natural cosmetics. Several variables are included in the regression analysis such as age, gender, consumers’ purchase tendency towards organic food, consumers’ new natural cosmetics brands and consumers’ tendency towards health consciousness. The data was collected through an online survey questionnaire using the purposive sample of 204 consumers from the Dubrovnik-Neretva County in March and April of 2015. Various statistical analyses were used such as binary logistic regression and correlation analysis. Binary logistic regression results show that gender, consumers’ purchase tendency towards organic food and consumers’ purchase tendency towards new natural cosmetics brands have an influence on consumer purchase intentions. However, consumers’ tendency towards health consciousness has no influence on consumers’ intentions towards purchasing natural cosmetics. Results of the correlation analysis indicate that there is a strong positive correlation between purchase intentions towards natural cosmetics and consumer references of natural cosmetics. The findings may be useful to online retailers, as well as marketers and practitioners to recognize and better understand the new trends that occur in the industry of natural cosmetics.

    We consider the steady group motions of a rigid body with a fixed point moving in a gravitational field. For an asymmetric top, rotation about the axis of gravity is the only permissible group motion; for a Lagrange top, simultaneous rotation about the axis of gravity and spin about the axis of symmetry of the top is permissible. Our analysis of the heavy top follows the reduced energy momentum method of Simo et al, which is applicable to a wide range of conservative systems with symmetry. St...

    Sn whiskers are observed by scanning electron microscope on the Cu surface in Cu(top)-Sn(bottom) bilayer system upon room temperature aging. Only Cu{sub 6}Sn{sub 5} phase appears in the X-ray diffraction patterns and no Sn element is detected in the Cu sublayer by scanning transmission electron microscopy. Based on the interfacial thermodynamics, the intermetallic Cu{sub 6}Sn{sub 5} compound phase may form directly at the Sn grain boundary. Driven by the stress gradient during the formation of Cu{sub 6}Sn{sub 5} compound at Sn grain boundaries, Sn atoms segregate onto the Cu surface and accumulate to form Sn whisker.

    The development of next-generation sequencing (NGS) technologies has provided novel tools for genome analysis and expression profiling. A high throughput cDNA sequencing method using a bench top next-generation sequencing system, GS Junior, is now available. Here, we used an alternative protocol to the standard method for generating the cDNA library. This protocol can decrease the number of processing steps to manipulate RNA when constructing a cDNA library from an RNA sample, and does not require mRNA isolation from total RNA. Thus it can decrease the risk of RNA degradation and the cost for preparing a cDNA library. Also, the efficiency of sequencing data obtained with this approach is comparable to the standard method as verified by sequencing characteristics and expression levels of the reference gene glyceraldehyde-3-phosphate dehydrogenase (GAPDH).

  7. Development of the detector control system for the ATLAS Level-1 trigger and measurement of the single top production cross section

    CERN Document Server

    Curtis, Christopher J

    This thesis discusses the development of the Detector Control System (DCS) for the ATLAS Level-1 Trigger. Microcontroller code has been developed to read out slow controls data from the Level-1 Calorimeter Trigger modules into the wider DCS. Back-end software has been developed for archiving this data. A Finite State Machine (FSM) has also been developed to offer remote access to the L1 Trigger hardware from the ATLAS Control Room. This Thesis also discusses the discovery potential for electroweak single top production during early running. Using Monte Carlo data some of the major systematics are discussed. A potential upper limit on the production cross section is calculated to be 45.2 pb. If the Standard Model prediction is assumed, a measured signal could potentially have a significance of up to 2.23¾ using 200 pb−1 of data.

    A new topping cycle coal power generation process has been developed as a Japanese national project for a high efficiency power generation process. This process consists of a pressurized bubbling fluidized-bed coal gasifier and a pressurized bubbling fluidized-bed combustor which combined in series. To evaluate the performance and to determine specification and operation parameters of this process, it is extremely important to analyze the behavior and the performance of the system by a reasonable simulation model. A simulation model of this new process is developed in this paper. It is demonstrated by calculating results from this model that the carbon conversion in the gasifier, the composition and the heating value of the produced gas are strongly dependent on operating conditions. Heat recovery by steam in the combustor is controlled by the coal feed rate. 7 refs., 9 figs.

  10. Linking top-down and bottom-up approaches for assessing the vulnerability of a 100 % renewable energy system in Northern-Italy

    Due to their variable and un-controllable features, integration of Variable Renewable Energies (e.g. solar-power, wind-power and hydropower, denoted as VRE) into the electricity network implies higher production variability and increased risk of not meeting demand. Two approaches are commonly used for assessing this risk and especially its evolution in a global change context (i.e. climate and societal changes); top-down and bottom-up approaches. The general idea of a top-down approach is to drive analysis of global change or of some key aspects of global change on their systems (e.g., the effects of the COP 21, of the deployment of Smart Grids, or of climate change) with chains of loosely linked simulation models within a predictive framework. The bottom-up approach aims to improve understanding of the dependencies between the vulnerability of regional systems and large-scale phenomenon from knowledge gained through detailed exploration of the response to change of the system of interest, which may reveal vulnerability thresholds, tipping points as well as potential opportunities. Brown et al. (2012) defined an analytical framework to merge these two approaches. The objective is to build, a set of Climate Response Functions (CRFs) putting in perspective i) indicators of desired states ("success") and undesired states ("failure") of a system as defined in collaboration with stakeholders 2) exhaustive exploration of the effects of uncertain forcings and imperfect system understanding on the response of the system itself to a plausible set of possible changes, implemented a with multi-dimensionally consistent "stress test" algorithm, and 3) a set "ex post" hydroclimatic and socioeconomic scenarios that provide insight into the differential effectiveness of alternative policies and serve as entry points for the provision of climate information to inform policy evaluation and choice. We adapted this approach for analyzing a 100 % renewable energy system within a region

    19th Edition of TOP500 List of World's Fastest Supercomputers Released MANNHEIM, Germany; KNOXVILLE, Tenn.;&BERKELEY, Calif. In what has become a much-anticipated event in the world of high-performance computing, the 19th edition of the TOP500 list of the worlds fastest supercomputers was released today (June 20, 2002). The recently installed Earth Simulator supercomputer at the Earth Simulator Center in Yokohama, Japan, is as expected the clear new number 1. Its performance of 35.86 Tflop/s (trillions of calculations per second) running the Linpack benchmark is almost five times higher than the performance of the now No.2 IBM ASCI White system at Lawrence Livermore National Laboratory (7.2 Tflop/s). This powerful leap frogging to the top by a system so much faster than the previous top system is unparalleled in the history of the TOP500.

    We consider the dynamics of the slightly asymmetric heavy top, a non-integrable system obtained from the Lagrange top by breaking the symmetry of its inertia tensor. It shows signs of weak chaos, which we study numerically. We argue that it is a good example for introducing students to non-integrability and chaos. (author)

  14. Policy options for pharmaceutical pricing and purchasing: issues for low- and middle-income countries.

    Science.gov (United States)

    Nguyen, Tuan Anh; Knight, Rosemary; Roughead, Elizabeth Ellen; Brooks, Geoffrey; Mant, Andrea

    2015-03-01

    Pharmaceutical expenditure is rising globally. Most high-income countries have exercised pricing or purchasing strategies to address this pressure. Low- and middle-income countries (LMICs), however, usually have less regulated pharmaceutical markets and often lack feasible pricing or purchasing strategies, notwithstanding their wish to effectively manage medicine budgets. In high-income countries, most medicines payments are made by the state or health insurance institutions. In LMICs, most pharmaceutical expenditure is out-of-pocket which creates a different dynamic for policy enforcement. The paucity of rigorous studies on the effectiveness of pharmaceutical pricing and purchasing strategies makes it especially difficult for policy makers in LMICs to decide on a course of action. This article reviews published articles on pharmaceutical pricing and purchasing policies. Many policy options for medicine pricing and purchasing have been found to work but they also have attendant risks. No one option is decisively preferred; rather a mix of options may be required based on country-specific context. Empirical studies in LMICs are lacking. However, risks from any one policy option can reasonably be argued to be greater in LMICs which often lack strong legal systems, purchasing and state institutions to underpin the healthcare system. Key factors are identified to assist LMICs improve their medicine pricing and purchasing systems.

  16. Top quark mass measurement

    Energy Technology Data Exchange (ETDEWEB)

    Maki, Tuula [Univ. of Helsinki (Finland)

    2008-03-18

    The top quark is the heaviest elementary particle. Its mass is one of the fundamental parameters of the standard model of particle physics, and an important input to precision electroweak tests. This thesis describes three measurements of the top-quark mass in the dilepton decay channel. The dilepton events have two neutrinos in the final state; neutrinos are weakly interacting particles that cannot be detected with a multipurpose experiment. Therefore, the signal of dilepton events consists of a large amount of missing energy and momentum carried off by the neutrinos. The top-quark mass is reconstructed for each event by assuming an additional constraint from a top mass independent distribution. Template distributions are constructed from simulated samples of signal and background events, and parametrized to form continuous probability density functions. The final top-quark mass is derived using a likelihood fit to compare the reconstructed top mass distribution from data to the parametrized templates. One of the analyses uses a novel technique to add top mass information from the observed number of events by including a cross-section-constraint in the likelihood function. All measurements use data samples collected by the CDF II detector.

    In this talk we summarize the top physics setup in the event generator WHIZARD with a main focus on lepton colliders. This includes full six-, eight- and ten-fermion processes, factorized processes and spin correlations. For lepton colliders, QCD NLO processes for top quark physics are available and will be discussed. A special focus is on the top-quark pair threshold, where a special implementation combines a non-relativistic effective-field theory calculation augmented by a next-to-leading threshold logarithm resummation with a continuum relativistic fixed-order QCD NLO simulation.

    In this talk we summarize the top physics setup in the event generator WHIZARD with a main focus on lepton colliders. This includes full six-, eight- and ten-fermion processes, factorized processes and spin correlations. For lepton colliders, QCD NLO processes for top quark physics are available and discussed. A special focus is on the top-quark pair threshold, where a special implementation combines a non-relativistic effective field theory calculation augmented by a next-to-leading threshold logarithm resummation with a continuum relativistic fixed-order QCD NLO simulation.

    Cohen, D A; Lesser, L I

    2016-05-01

    The point of purchase is when people may make poor and impulsive decisions about what and how much to buy and consume. Because point of purchase strategies frequently work through non-cognitive processes, people are often unable to recognize and resist them. Because people lack insight into how marketing practices interfere with their ability to routinely eat healthy, balanced diets, public health entities should protect consumers from potentially harmful point of purchase strategies. We describe four point of purchase policy options including standardized portion sizes; standards for meals that are sold as a bundle, e.g. 'combo meals'; placement and marketing restrictions on highly processed low-nutrient foods; and explicit warning labels. Adoption of such policies could contribute significantly to the prevention of obesity and diet-related chronic diseases. We also discuss how the policies could be implemented, along with who might favour or oppose them. Many of the policies can be implemented locally, while preserving consumer choice.

    TACSI whole blood system is designed to combine primary and secondary processing of six whole blood bags into plasma units, buffy coat and red blood cell concentrates. The aim of this study was to investigate the specifications and in vitro storage parameters of blood components compared with standard centrifugation and separation processing. Whole blood bags, collected in CRC kits, were treated on a TACSI whole blood system. They were compared with whole blood bags collected in Composelect kits. In addition to routine quality control analyses, conservation studies were performed on red blood cell concentrates for 42 days and on plasma for 6 months. Platelets pools with five buffy coats were also created, and cellular contamination was evaluated. Red blood cell concentrates produced from TACSI whole blood met European quality requirements. For white blood cell count, one individual result exceeded 1 × 10(6) cells/unit. All plasma units fell within specifications for residual cellular contamination and storage parameters. The performances of the TACSI whole blood system allow for the preparation of low volume buffy coats with a recovery of 90% of whole blood platelets. Haemoglobin losses in TACSI BC are smaller, but this did not result in higher haemoglobin content of red cells. These BC are suitable for the production of platelet concentrates. From these in vitro data, red blood cell concentrates produced using TACSI whole blood are suitable for clinical use with a quality at least equivalent to the control group. © 2014 International Society of Blood Transfusion.

    As self-medication with nonprescription drugs becomes increasingly popular and important in this era of escalating health care costs and growing consumer sophistication, the degree of consumer involvement in the purchase decision becomes an important factor. High involvement suggests active information-seeking behavior and, therefore, a greater likelihood of appropriate nonprescription drug use. The authors assess consumer involvement in nonprescription medicine purchase decisions and the use of expert sources of information.

  12. Search for supersymmetric top-quark partners using support vector machines and upgrade of the hadron calorimeter front-end readout control system at CMS

    Energy Technology Data Exchange (ETDEWEB)

    Sahin, Mehmet Oezguer

    2017-04-15

    In this thesis a search for direct pair production of supersymmetric top-quark partners as well as work on the upgrade of the front-end readout controller of the Hadron Calorimeter (HCAL) of the Compact Muon Solenoid (CMS) experiment are presented. The most appealing extension of the Standard Model (SM) is supersymmetry (SUSY), relating the integer spin (bosons) and half-integer spin elementary particles (fermions). Supersymmetric top-quark partners (t) around and below the TeV energy scale offer a solution to the hierarchy problem. Furthermore, R-parity conserving SUSY models propose a cold dark matter candidate in the form of stable lightest supersymmetric particles, e.g. lightest neutralinos (χ{sup 0}). The analysis performed in this thesis is a search for top-squark pair production in a final state consisting of a single isolated lepton, jets, among which at least one is tagged as bottom-quark jet, and large missing transverse energy at the CMS experiment at the CERN Large Hadron Collider (LHC) with 8 TeV center-of-mass energy. A new Support Vector Machines (SVM) High-Energy Physics interface (SVM-HINT) software is introduced to classify signal events originating from new physics processes and the SM background. SVM-HINT is enhanced with a novel statistical significance based optimization algorithm providing a state-of-the-art classification power. Monte Carlo simulations are used in the training and optimization procedure, and high signal purity search regions are determined in the search for top-squark pair production. The background event yields in each search region are predicted using a data-driven background estimation method. The results are interpreted within a simplified model assuming a branching ratio of 100% to t → tχ{sup 0}. No significant discrepancy between the data and the SM predictions has been observed. Exclusion limits were derived to constrain the m{sub t} and m{sub χ{sup 0}} of the investigated simplified model. The sensitivity of the

    Full Text Available The aim of this study was to examine the physical demands imposed on professional soccer players during 11-a-side friendly matches in relation to their playing position, using global positioning system (GPS technology. One hundred and eleven match performances of a Spanish “La Liga” team during the 2010-11 and 2011-12 pre-seasons were selected for analysis. The activities of the players were monitored using GPS technology with a sampling frequency of 1 Hz. Total distance covered, distance in different speed categories, accelerations, and heart rate responses were analyzed in relation to five different playing positions: central defenders (n=23, full-backs (n=20, central midfielders (n=22, wide midfielders (n=26, and forwards (n=20. Distance covered during a match averaged 10.8 km, with wide and central midfielders covering the greatest total distance. Specifically, wide midfielders covered the greatest distances by very high-intensity running (>19.8 km·h-1 and central midfielders by jogging and running (7.2-19.7 km·h-1. On the other hand, central defenders covered the least total distance and at high intensity, although carried out more (p<0.05-0.01 accelerations than forwards, wide midfielders, and fullbacks. The work rate profile of the players obtained with the GPS was very similar to that obtained with semi-automatic image technologies. However, when comparing results from this study with data available in the literature, important differences were detected in the amount of distance covered by sprinting, which suggests that caution should be taken when comparing data obtained with the GPS with other motion analysis systems, especially regarding high-intensity activities.

  19. Top Quark Mass

    Science.gov (United States)

    Mulders, Martijn

    2016-10-01

    Ever since the discovery of the top quark at the Tevatron collider in 1995 the measurement of its mass has been a high priority. As one of the fundamental parameters of the Standard Theory of particle physics, the precise value of the top quark mass together with other inputs provides a test for the self-consistency of the theory, and has consequences for the stability of the Higgs field that permeates the Universe. In this review I will briefly summarize the experimental techniques used at the Tevatron and the LHC experiments throughout the years to measure the top quark mass with ever improving accuracy, and highlight the recent progress in combining all measurements in a single world average combination. As experimental measurements became more precise, the question of their theoretical interpretation has become important. The difficulty of relating the measured quantity to the fundamental top mass parameter has inspired alternative measurement methods that extract the top mass in complementary ways. I will discuss the status of those techniques and their results, and present a brief outlook of further improvements in the experimental determination of the top quark mass to be expected at the LHC and beyond.

    The aim of the present work was to evaluate the influence of two front-of-pack nutrition information schemes (traffic-light system and Chilean warning system) on consumer purchase of ultra-processed foods in a simulated online grocery store. Following a between-subjects design, participants completed a simulated weekly food purchase in an online grocery store under one of three experimental conditions: (i) a control condition with no nutrition information, (ii) a traffic-light system and (iii) the Chilean warning system. Information about energy (calories), sugar, saturated fats and salt content was included in the nutrition information schemes. Participants were recruited from a consumer database and a Facebook advertisement. People from Montevideo (Uruguay), aged 18-77 years (n 437; 75 % female), participated in the study. All participants were in charge of food purchase in the household, at least occasionally. No significant differences between experimental conditions were found in the mean share of ultra-processed foods purchased by participants, both in terms of number of products and expenditure, or in the mean energy, sugar, saturated fat and salt content of the purchased items. However, the Chilean warning system decreased intended purchase of sweets and desserts. Results from this online simulation provided little evidence to suggest that the traffic-light system or the Chilean warning system in isolation could be effective in reducing purchase of ultra-processed foods or improving the nutritional composition of the purchased products.

    2016-01-01

    The purpose of this study was to assess the effect of table and seat slope on the biomechanical stress sustained by the musculo-skeletal system. Angular position of the head and trunk, and surface electromyography of eleven postural muscles were recorded while seated under different conditions of seat slope (0°, 15° forward) and table slope (0°, 20° backward). The specific stress sustained by C7-T1 joint was estimated with isometric torque calculation. The results showed that the backward sloping table was associated with a reduction of neck flexion and neck extensors EMG, contrasting with a concurrent overactivity of the deltoideus. The forward sloping chair induced an anterior pelvic tilt, but also a higher activity of the knee (vasti) and ankle (soleus) extensors. It was concluded that sloping chairs and tables favor a more erect posture of the spine, but entails an undesirable overactivity of upper and lower limbs muscles to prevent the body from sliding.

  14. Preference alters consumptive effects of predators: top-down effects of a native crab on a system of native and introduced prey.

    Full Text Available Top-down effects of predators in systems depend on the rate at which predators consume prey, and on predator preferences among available prey. In invaded communities, these parameters might be difficult to predict because ecological relationships are typically evolutionarily novel. We examined feeding rates and preferences of a crab native to the Pacific Northwest, Cancer productus, among four prey items: two invasive species of oyster drill (the marine whelks Urosalpinx cinerea and Ocenebra inornata and two species of oyster (Crassostrea gigas and Ostrea lurida that are also consumed by U. cinerea and O. inornata. This system is also characterized by intraguild predation because crabs are predators of drills and compete with them for prey (oysters. When only the oysters were offered, crabs did not express a preference and consumed approximately 9 juvenile oysters crab(-1 day(-1. We then tested whether crabs preferred adult drills of either U. cinerea or O. inornata, or juvenile oysters (C. gigas. While crabs consumed drills and oysters at approximately the same rate when only one type of prey was offered, they expressed a strong preference for juvenile oysters over drills when they were allowed to choose among the three prey items. This preference for oysters might negate the positive indirect effects that crabs have on oysters by crabs consuming drills (trophic cascade because crabs have a large negative direct effect on oysters when crabs, oysters, and drills co-occur.

    Research demonstrates that food desert environments limit low-income shoppers' ability to purchase healthy foods, thereby increasing their likelihood of diet-related illnesses. We sought to understand how individuals in an urban American food desert make grocery-purchasing decisions, and specifically why unhealthy purchases arise. Analysis is based on ethnographic data from participant observation, 37 in-depth interviews, and three focus groups with low-income, primarily African American shoppers with children. We found participants had detailed knowledge of and preference for healthy foods, but the obligation to consistently provide food for their families required them to apply specific decision criteria which, combined with structural qualities of the supermarket environment, increased unhealthy purchases and decreased healthy purchases. Applying situated cognition theory, we constructed an emic model explaining this widely shared grocery-purchasing decision process and its implications. This context-specific understanding of behavior suggests that multifaceted, system-level approaches to intervention are needed to increase healthy purchasing in food deserts.

    This study examined the relationship between the neighborhood food environment and the food purchasing behaviors among adolescents. Grade 7 and 8 students (n = 810) at 21 elementary schools in London, Ontario, Canada completed a questionnaire assessing their food purchasing behaviors. Parents of participants also completed a brief questionnaire providing residential address and demographic information. A Geographic Information System (GIS) was used to assess students' home and school neighborhood food environment and land use characteristics. Logistic regression analysis was conducted to assess the influence of the home neighborhood food environment on students' food purchasing behaviors, while two-level Hierarchical Non-Linear Regression Models were used to examine the effects of school neighborhood food environment factors on students' food purchasing behaviors. The study showed that approximately 65% of participants reported self-purchasing foods from fast-food outlets or convenience stores. Close proximity (i.e., less than 1 km) to the nearest fast-food outlet or convenience store in the home neighborhood increased the likelihood of food purchasing from these food establishments at least once per week by adolescents (p fast-food outlet density in both home and school neighborhoods was associated with increased fast-food purchasing by adolescents (i.e., at least once per week; p food environment surrounding children and youth's home and school.

High fast-food outlet density in both home and school neighborhoods was associated with increased fast-food purchasing by adolescents (i.e., at least once per week; p < 0.05. In conclusion, macro-level regulations and policies are required to amend the health-detracting neighborhood food environment surrounding children and youth’s home and school.

    Factors that have affected hospital pharmacy purchasing and inventory control functions are discussed, and future trends are suggested. The concepts of the pharmacy and therapeutics committee and the hospital formulary system stemmed from early hospital pharmacy practice standards that were promulgated about the time drug products began to proliferate. Brand standardization, restricted drug-use policies, and selection of therapeutic alternates are among the approaches P & T committees have devised to hold down hospital drug costs; these efforts will expand. Brand-comparison advertising, use of various incentives to physicians and pharmacists, premarketing publicity about new products, improved product packaging, and support of research studies are among the promotional tactics pharmaceutical manufacturers have employed and are likely to expand. Government legislation and regulations that have had the effect of increasing the cost of drugs may be modified. Hospital pharmacists should monitor developments such as these to prepare themselves for the challenges in their purchasing and inventory control responsibilities.

    Nitrogen isotopes are often used to trace the trophic level of members of an ecosystem. As part of a stable isotope biogeochemistry and forensics course at Purdue University, students are introduced to this concept by analyzing nitrogen isotopes in sea food purchased from local grocery stores. There is a systematic increase in 15N/14N ratios going from kelp to clams/shrimp, to sardines, to tuna and finally to shark. These enrichments demonstrate how nitrogen is enriched in biomass as predators consume prey. Some of the highest nitrogen isotope enrichments observed, however, are in the common guppy. We investigated a number of aquarium fish foods and find they typically have high nitrogen isotope ratios because they are made form fish meal that is produced primarily from the remains of predator fish such as tuna. From, a isotope perspective, the guppy is the top of the food chain, more ferocious than even the Great White shark.
