    While much research has focused on intake and eating behaviors of young adolescents, few studies have examined their knowledge of the Nutrition Facts label. The goals of this project were to assess the understanding of Nutrition Facts labels and the response of young adolescents to an educational program about Nutrition Facts labels. Thirty-four young adolescents participated by answering a short questionnaire and taking a pretest about Nutrition Facts labels and their food choices, which involved using actual Nutrition Facts labels from foods typically eaten by adolescents. Then the subjects participated in a short educational program on how to read the Nutrition Facts label. This was followed by a posttest. Initial knowledge of the basic use of the Nutrition Facts label was marginal, with only 6.65 (standard deviation=2.23) or approximately 55% of pretest questions answered correctly. However, the subjects' scores improved significantly to 8.32 (standard deviation=2.01) or approximately 70% correct on the posttest (P<0.0001, Fisher's exact test) after the educational session. In conclusion, young adolescents can learn how to read and understand the Nutrition Facts labels through educational sessions.

    Appliance ownership and production has increased dramatically in China in the past two decades. From extremely low levels in 1980, China's appliance industry has become one of the largest in the world, with sales topping U.S. $14.4 billion in 2000. In 1981, less than 1 percent of urban Chinese households owned a refrigerator; by 1998, that number had increased to over 75 percent. This dramatic increase in sales and ownership leads to an excellent opportunity to impact energy consumption in China by affecting the energy efficiency of appliances being bought and sold. In general, Chinese consumers value energy efficiency and are knowledgeable about the operating costs of major appliances. However, the Chinese marketplace does not provide information that consumers trust about the energy consumption of specific products. Thus, several interdependent organizations have emerged in China to provide information and market supports for energy efficiency. This paper describes the appliance market in China and the evolution of its standards and labeling programs and the agencies that implement them. It discusses the authors' work with these organizations in developing energy efficiency criteria and supporting an energy efficiency endorsement labeling program in China. It describes how the authors have used their experience with ENERGY STAR{reg_sign} and other programs in the U.S. to work with China to develop a successful program specific to Chinese conditions, with a particular emphasis on refrigerators. It then gives the author's market assessment of the Chinese refrigerator market and recommendations for a successful labeling program and transferable lessons for developing energy efficiency labeling programs in varied markets. This paper is based on the authors' market research, their support in setting energy efficiency criteria in China, interviews with Chinese manufacturers, retailers, and sales staff, and the development and implementation of

    because consumers will avoid products that the label shows to be nutritionally deficient, but also because food producers will try to avoid marketing products that appear, according to the label, as nutritionally problematic, for example, because of a high content of saturated fat or salt. Nutrition......Nutrition labeling refers to the provision of information on a food product’s nutritional content on the package label. It can serve both public health and commercial purposes. From a public health perspective, the aim of nutrition labeling is to provide information that can enable consumers...... to make healthier choices when choosing food products. Nutrition labeling is thus closely linked to the notion of the informed consumer, that chooses products according to their aims, on the basis of the information at their disposal.

    Nutrition labeling regulations differ in countries around the world. The focus of this chapter is on nutrition labeling regulations in the USA, as specified by the Food and Drug Administration (FDA) and the Food Safety and Inspection Service (FSIS) of the United States Department of Agriculture (USDA). A major reason for analyzing the chemical components of foods in the USA is nutrition labeling regulations. Nutrition label information is not only legally required in many countries, but also is of increasing importance to consumers as they focus more on health and wellness.

    This paper presents current and projected savings for ENERGY STAR labeled products, and details the status of the model as implemented in the September 2009 spreadsheets. ENERGY STAR is a voluntary energy efficiency labeling program operated jointly by the Environmental Protection Agency (US EPA) and the U.S. Department of Energy (US DOE), designed to identify and promote energy-efficient products, buildings and practices. Since the program inception in 1992, ENERGY STAR has become a leading international brand for energy efficient products, and currently labels more than thirty products, spanning office equipment, heating, cooling and ventilation equipment, commercial and residential lighting, home electronics, and major appliances. ENERGY STAR's central role in the development of regional, national and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with stakeholders. This report presents savings estimates for ENERGY STAR labeled products. We present estimates of energy, dollar, and carbon savings achieved by the program in the year 2008, annual forecasts for 2009 and 2010, and cumulative savings estimates for the period 1993 through 2008 and cumulative forecasts for the period 2009 through 2015. Through 2008 the program saved 8.8 Quads of primary energy and avoided the equivalent of 158 metric tones carbon (MtC). The forecast for the period 2009-2015 is 18.1 Quads or primary energy saved and 316 MtC emissions avoided. The sensitivity analysis bounds the best estimate of carbon avoided between 104 MtC and 213 MtC (1993 to 2008) and between 206 MtC and 444 MtC (2009 to 2015). In this report we address the following questions for ENERGY STAR labeled products: (1) How are ENERGY STAR impacts quantified; (2) What are the ENERGY STAR achievements; and (3) What are the limitations to our method?

  19. Beyond Maximum Independent Set: An Extended Integer Programming Formulation for Point Labeling

    Directory of Open Access Journals (Sweden)

    Jan-Henrik Haunert

    2017-11-01

    Full Text Available Map labeling is a classical problem of cartography that has frequently been approached by combinatorial optimization. Given a set of features in a map and for each feature a set of label candidates, a common problem is to select an independent set of labels (that is, a labeling without label–label intersections that contains as many labels as possible and at most one label for each feature. To obtain solutions of high cartographic quality, the labels can be weighted and one can maximize the total weight (rather than the number of the selected labels. We argue, however, that when maximizing the weight of the labeling, the influences of labels on other labels are insufficiently addressed. Furthermore, in a maximum-weight labeling, the labels tend to be densely packed and thus the map background can be occluded too much. We propose extensions of an existing model to overcome these limitations. Since even without our extensions the problem is NP-hard, we cannot hope for an efficient exact algorithm for the problem. Therefore, we present a formalization of our model as an integer linear program (ILP. This allows us to compute optimal solutions in reasonable time, which we demonstrate both for randomly generated point sets and an existing data set of cities. Moreover, a relaxation of our ILP allows for a simple and efficient heuristic, which yielded near-optimal solutions for our instances.

    The food industry develops tasty and healthy food but fails to deliver the message to all consumers. The consumers’ background knowledge is essential for how they find and decode relevant elements in the cocktail of signs which fight for attention on food labels. In this exploratory study, we find...... evidence for dividing consumers into two profiles: one relying on general food knowledge and another using knowledge related to signpost labels. In a combined eyetracking and questionnaire survey we analyse the influence of background knowledge and identify different patterns of visual attention...... for the two consumer profiles. This underlines the complexity in choosing and designing the ‘right’ elements for a food package that consumers actually look at and are able to make rational use of.

    2008-10-31

    ENERGY STAR is a voluntary energy efficiency-labeling program operated jointly by the United States Department of Energy and the United States Environmental Protection Agency (US EPA). Since the program inception in 1992, ENERGY STAR has become a leading international brand for energy efficient products. ENERGY STAR's central role in the development of regional, national, and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with committed stakeholders. Through 2007, the program saved 7.1 Quads of primary energy and avoided 128 MtC equivalent. The forecast shows that the program is expected to save 21.2 Quads of primary energy and avoid 375 MtC equivalent over the period 2008-2015. The sensitivity analysis bounds the best estimate of carbon avoided between 84 MtC and 172 MtC (1993 to 2007) and between 243 MtC and 519 MtC (2008 to 2015).

  7. Dynamic Programming for Instance Annotation in Multi-Instance Multi-Label Learning.

    Science.gov (United States)

    Pham, Anh T; Raich, Raviv; Fern, Xiaoli Z

    2017-12-01

    Labeling data for classification requires significant human effort. To reduce labeling cost, instead of labeling every instance, a group of instances (bag) is labeled by a single bag label. Computer algorithms are then used to infer the label for each instance in a bag, a process referred to as instance annotation. This task is challenging due to the ambiguity regarding the instance labels. We propose a discriminative probabilistic model for the instance annotation problem and introduce an expectation maximization framework for inference, based on the maximum likelihood approach. For many probabilistic approaches, brute-force computation of the instance label posterior probability given its bag label is exponential in the number of instances in the bag. Our contribution is a dynamic programming method for computing the posterior that is linear in the number of instances. We evaluate our method using both benchmark and real world data sets, in the domain of bird song, image annotation, and activity recognition. In many cases, the proposed framework outperforms, sometimes significantly, the current state-of-the-art MIML learning methods, both in instance label prediction and bag label prediction.

    Transmission and distribution (T&D) losses in electricity networks represent 8.5% of final energy consumption in the world. In Latin America, T&D losses range between 6% and 20% of final energy consumption, and represent 7% in Chile. Because approximately one-third of T&D losses take place in distribution transformers alone, there is significant potential to save energy and reduce costs and carbon emissions through policy intervention to increase distribution transformer efficiency. A large number of economies around the world have recognized the significant impact of addressing distribution losses and have implemented policies to support market transformation towards more efficient distribution transformers. As a result, there is considerable international experience to be shared and leveraged to inform countries interested in reducing distribution losses through policy intervention. The report builds upon past international studies of standards and labeling (S&L) programs for distribution transformers to present the current energy efficiency programs for distribution transformers around the world.

  12. Global Potential of Energy Efficiency Standards and Labeling Programs

    Energy Technology Data Exchange (ETDEWEB)

    McNeil, Michael A; McNeil, Michael A.; Letschert, Virginie; de la Rue du Can, Stephane

    2008-06-15

    This report estimates the global potential reductions in greenhouse gas emissions by 2030 for energy efficiency improvements associated with equipment (appliances, lighting, and HVAC) in buildings by means of energy efficiency standards and labels (EES&L). A consensus has emerged among the world's scientists and many corporate and political leaders regarding the need to address the threat of climate change through emissions mitigation and adaptation. A further consensus has emerged that a central component of these strategies must be focused around energy, which is the primary generator of greenhouse gas emissions. Two important questions result from this consensus: 'what kinds of policies encourage the appropriate transformation to energy efficiency' and 'how much impact can these policies have'? This report aims to contribute to the dialogue surrounding these issues by considering the potential impacts of a single policy type, applied on a global scale. The policy addressed in this report is Energy Efficient Standards and Labeling (EES&L) for energy-consuming equipment, which has now been implemented in over 60 countries. Mandatory energy performance standards are important because they contribute positively to a nation's economy and provide relative certainty about the outcome (both timing and magnitudes). Labels also contribute positively to a nation's economy and importantly increase the awareness of the energy-consuming public. Other policies not analyzed here (utility incentives, tax credits) are complimentary to standards and labels and also contribute in significant ways to reducing greenhouse gas emissions. We believe the analysis reported here to be the first systematic attempt to evaluate the potential of savings from EES&L for all countries and for such a large set of products. The goal of the analysis is to provide an assessment that is sufficiently well-quantified and accurate to allow comparison and integration

    2010-08-01

    After implementing several energy efficiency standards and labels (30 products covered by MEPS, 50 products covered by voluntary labels and 19 products by mandatory labels), the China National Institute of Standardization (CNIS) is now implementing verification and compliance mechanism to ensure that the energy information of labeled products comply with the requirements of their labels. CNIS is doing so by organizing check testing on a random basis for room air-conditioners, refrigerators, motors, heaters, computer displays, ovens, and self -ballasted lamps. The purpose of the check testing is to understand the implementation of the Chinese labeling scheme and help local authorities establishing effective compliance mechanisms. In addition, to ensure robustness and consistency of testing results, CNIS has coordinated a round robin testing for room air conditioners. Eight laboratories (Chinese (6), Australian (1) and Japanese (1)) have been involved in the round robin testing and tests were performed on four sets of samples selected from manufacturer's production line. This paper describes the methodology used in undertaking both check and round robin testing, provides analysis of testing results and reports on the findings. The analysis of both check and round robin testing demonstrated the benefits of a regularized verification and monitoring system for both laboratories and products such as (i) identifying the possible deviations between laboratories to correct them, (ii) improving the quality of testing facilities, (iii) ensuring the accuracy and reliability of energy label information in order to strength the social credibility of the labeling program and the enforcement mechanism in place.

That proof involved two distinct steps: a lower bound for a problem they call prefix bucketing and a reduction from prefix bucketing to online labeling. The reduction seems to be incorrect, leaving a (seemingly significant......) gap in the proof. In this paper we close the gap by presenting a correct reduction to prefix bucketing. Furthermore we give a simplified and improved analysis of the prefix bucketing lower bound. This improvement allows us to extend the lower bounds for online labeling to the case where the number m...

    2014-12-01

    To describe and provide recommendations for the implementation of an evaluation for an already existing, in-store Nutrition Label Education Program (NLEP). We describe the development and implementation of an evaluation consisting of a pre- and postsurvey and one month follow-up. The evaluation was designed to assess satisfaction with the NLEP as well as changes in participant nutrition label knowledge, confidence in using nutrition labels, and actual changes in nutrition label use. Nineteen participants took part in the pilot evaluation. The evaluation was successful in demonstrating high levels of satisfaction with the NLEP as well as positive changes in participant confidence and some increased knowledge in using nutrition labels. However, only 3 people participated in the follow-up, limiting the ability to assess behaviour change. Ideally, NLEPs should include ongoing evaluation that extends beyond just assessing participant satisfaction. Recommendations are provided for conducting such evaluations, including the importance of incorporating the evaluation into the program itself, using existing questionnaires when possible, and employing pre- and postsurveys as well as follow-up interviews to assess change.

    2012-02-28

    Appliance energy efficiency standards and labeling (S&L) programs have been important policy tools for regulating the efficiency of energy-using products for over 40 years and continue to expand in terms of geographic and product coverage. The most common S&L programs include mandatory minimum energy performance standards (MEPS) that seek to push the market for efficient products, and energy information and endorsement labels that seek to pull the market. This study seeks to review and compare some of the earliest and most well-developed S&L programs in three countries and one region: the U.S. MEPS and ENERGY STAR, Australia MEPS and Energy Label, European Union MEPS and Ecodesign requirements and Energy Label and Japanese Top Runner programs. For each program, key elements of S&L programs are evaluated and comparative analyses across the programs undertaken to identify best practice examples of individual elements as well as cross-cutting factors for success and lessons learned in international S&L program development and implementation. The international review and comparative analysis identified several overarching themes and highlighted some common factors behind successful program elements. First, standard-setting and programmatic implementation can benefit significantly from a legal framework that stipulates a specific timeline or schedule for standard-setting and revision, product coverage and legal sanctions for non-compliance. Second, the different MEPS programs revealed similarities in targeting efficiency gains that are technically feasible and economically justified as the principle for choosing a standard level, in many cases at a level that no product on the current market could reach. Third, detailed survey data such as the U.S. Residential Energy Consumption Survey (RECS) and rigorous analyses provide a strong foundation for standard-setting while incorporating the participation of different groups of stakeholders further strengthen the process

    1985-01-01

    A capacitive label reader includes an outer ring transmitting portion, an inner ring transmitting portion, and a plurality of insulated receiving portions. A label is the mirror-image of the reader except that identifying portions corresponding to the receiving portions are insulated from only one of two coupling elements. Positive and negative pulses applied, respectively, to the two transmitting rings biased a CMOS shift register positively to either a 1 or 0 condition. The output of the CMOS may be read as an indication of the label.

    2009-09-24

    This report provides a top-level summary of national savings achieved by the Energy Star voluntary product labeling program. To best quantify and analyze savings for all products, we developed a bottom-up product-based model. Each Energy Star product type is characterized by product-specific inputs that result in a product savings estimate. Our results show that through 2007, U.S. EPA Energy Star labeled products saved 5.5 Quads of primary energy and avoided 100 MtC of emissions. Although Energy Star-labeled products encompass over forty product types, only five of those product types accounted for 65percent of all Energy Star carbon reductions achieved to date, including (listed in order of savings magnitude)monitors, printers, residential light fixtures, televisions, and furnaces. The forecast shows that U.S. EPA?s program is expected to save 12.2 Quads of primary energy and avoid 215 MtC of emissions over the period of 2008?2015.

    2011-09-26

    As part of its commitment to promoting and improving the local enforcement of appliance energy efficiency standards and labeling, the China National Institute of Standardization (CNIS) launched the National and Local Enforcement of Energy Efficiency Standards and Labeling project on August 14, 2009. The project’s short-term goal is to expand the effort to improve enforcement of standards and labeling requirements to the entire country within three years, with a long-term goal of perfecting overall enforcement. For this project, Jiangsu, Shandong, Sichuan and Shanghai were selected as pilot locations. This report provides information on the local enforcement project’s recent background, activities and results as well as comparison to previous rounds of check-testing in 2006 and 2007. In addition, the report also offers evaluation on the achievement and weaknesses in the local enforcement scheme and recommendations. The results demonstrate both improvement and some backsliding. Enforcement schemes are in place in all target cities and applicable national standards and regulations were followed as the basis for local check testing. Check testing results show in general high labeling compliance across regions with 100% compliance for five products, including full compliance for all three products tested in Jiangsu province and two out of three products tested in Shandong province. Program results also identified key weaknesses in labeling compliance in Sichuan as well as in the efficiency standards compliance levels for small and medium three-phase asynchronous motors and self-ballasted fluorescent lamps. For example, compliance for the same product ranged from as low as 40% to 100% with mixed results for products that had been tested in previous rounds. For refrigerators, in particular, the efficiency standards compliance rate exhibited a wider range of 50% to 100%, and the average rate across all tested models also dropped from 96% in 2007 to 63%, possibly due to

    This book is aimed at providing an overview of several aspects of semantic role labeling. Chapter 1 begins with linguistic background on the definition of semantic roles and the controversies surrounding them. Chapter 2 describes how the theories have led to structured lexicons such as FrameNet, VerbNet and the PropBank Frame Files that in turn provide the basis for large scale semantic annotation of corpora. This data has facilitated the development of automatic semantic role labeling systems based on supervised machine learning techniques. Chapter 3 presents the general principles of applyin

    Full Text Available Generating multi-label rules in associative classification (AC from single label data sets is considered a challenging task making the number of existing algorithms for this task rare. Current AC algorithms produce only the largest frequency class connected with a rule in the training data set and discard all other classes even though these classes have data representation with the rule’s body. In this paper, we deal with the above problem by proposing an AC algorithm called Enhanced Multi-label Classifiers based Associative Classification (eMCAC. This algorithm discovers rules associated with a set of classes from single label data that other current AC algorithms are unable to induce. Furthermore, eMCAC minimises the number of extracted rules using a classifier building method. The proposed algorithm has been tested on a real world application data set related to website phishing and the results reveal that eMCAC’s accuracy is highly competitive if contrasted with other known AC and classic classification algorithms in data mining. Lastly, the experimental results show that our algorithm is able to derive new rules from the phishing data sets that end-users can exploit in decision making.

    In this report, we describe the necessary data inputs for both standards development and program evaluation and perform an initial assessment of the availability and uncertainty of those data inputs in China. For standards development, we find that China and its standards and labeling program administrators currently has access to the basic market and technical data needed for conducting market and technology assessment and technological and economic analyses. Some data, such as shipments data, is readily available from the China Energy Label product registration database while the availability of other data, including average unit energy consumption, prices and design options, needs improvement. Unlike some other countries such as the United States, most of the necessary data for conducting standards development analyses are not publicly available or compiled in a consolidated data source. In addition, improved data on design and efficiency options as well as cost data (e.g., manufacturing costs, mark-ups, production and product use-phase costs) – key inputs to several technoeconomic analyses – are particularly in need given China’s unconsolidated manufacturing industry. For program evaluation, we find that while China can conduct simple savings evaluations on its incentive programs with the data it currently has available from the Ministry of Finance – the program administrator, the savings estimates produced by such an evaluation will carry high uncertainty. As such, China could benefit from an increase in surveying and metering in the next one to three years to decrease the uncertainty surrounding key data points such as unit energy savings and free ridership.

    2007-06-12

    This study analyzes impacts from energy efficiency standards and labeling in Mexico from 1994 through 2005 for four major products: household refrigerators, room air conditioners, three-phase (squirrel cage) induction motors, and clothes washers. It is a retrospective analysis, seeking to assess verified impacts on product efficiency in the Mexican market in the first ten years after standards were implemented. Such an analysis allows the Mexican government to compare actual to originally forecast program benefits. In addition, it provides an extremely valuable benchmark for other countries considering standards, and to the energy policy community as a whole. The methodology for evaluation begins with historical test data taken for a large number of models of each product type between 1994 and 2005. The pre-standard efficiency of models in 1994 is taken as a baseline throughout the analysis. Model efficiency data were provided by an independent certification laboratory (ANCE), which tested products as part of the certification and enforcement mechanism defined by the standards program. Using this data, together with economic and market data provided by both government and private sector sources, the analysis considers several types of national level program impacts. These include: Energy savings; Environmental (emissions) impacts, and Net financial impacts to consumers, manufacturers and utilities. Energy savings impacts are calculated using the same methodology as the original projections, allowing a comparison.

    Labelling theory is a perspective that emerged as a distinctive approach to criminology during the 1960s, and was a major seedbed of the radical and critical perspectives that became prominent in the 1970s. It represented the highpoint of an epistemological shift within the social sciences away from positivism – which had dominated criminological enquiry since the late-1800s – and toward an altogether more relativistic stance on the categories and concepts of crime and control. It inspired a ...

    Map labeling is of fundamental importance in cartography and geographical information systems and is one of the areas targeted for research by the ACM Computational Geometry Impact Task Force. Previous work on map labeling has focused on the problem of placing maximal uniform, axis-aligned, disjoint rectangles on the plane so that each point feature to be labeled lies at the corner of one rectangle. Here, we consider a number of variants of the map labeling problem. We obtain three general types of results. First, we devise constant-factor polynomial-time-approximation algorithms for labeling point features by rectangular labels, where the feature may lie anywhere on the boundary of its label region and where labeling rectangles may be placed in any orientation. These results generalize to the case of elliptical labels. Secondly, we consider the problem of labeling a map consisting of disjoint rectilinear fine segments. We obtain constant-factor polynomial-time approximation algorithms for the general problem and an optimal algorithm for the special case where all segments are horizontal. Finally, we formulate a bicriteria version of the map-labeling problem and provide bicriteria polynomial- time approximation schemes for a number of such problems.

  16. Acting Globally: Potential Carbon Emissions Mitigation Impacts from an International Standards and Labelling Program

    Energy Technology Data Exchange (ETDEWEB)

    McNeil, Michael A; Letschert, Virginie E.; de la Rue du Can, Stephane; Egan, Christine

    2009-05-29

    This paper presents an analysis of the potential impacts of an international initiative designed to support and promote the development and implementation of appliances standards and labelling programs throughout the world. As part of previous research efforts, LBNL developed the Bottom Up Energy Analysis System (BUENAS), an analysis framework that estimates impact potentials of energy efficiency policies on a global scale. In this paper, we apply this framework to an initiative that would result in the successful implementation of programs focused on high priority regions and product types, thus evaluating the potential impacts of such an initiative in terms of electricity savings and carbon mitigation in 2030. In order to model the likely parameters of such a program, we limit impacts to a five year period starting in 2009, but assume that the first 5 years of a program will result in implementation of 'best practice' minimum efficiency performance standards by 2014. The 'high priority' regions considered are: Brazil, China, the European Union,India, Mexico and the United States. The products considered are: refrigerators, air conditioners, lighting (both fluorescent and incandescent), standby power (for consumer electronics) and televisions in the residential sector, and air conditioning and lighting in commercial buildings. In 2020, these regions and enduses account for about 37percent of global residential electricity and 29percent of electricity in commercial buildings. We find that 850Mt of CO2 could be saved in buildings by 2030 compared to the baseline forecast.

    2012-01-01

    The US Food and Drug Administration’s forthcoming national menu labeling regulations are designed to help curb the national obesity epidemic by requiring calorie counts on restaurants’ menus. However, posted calories can be easily ignored or misunderstood by consumers and fail to accurately describe the healthiness of foods. We propose supplemental models that include nutritional information (e.g., fat, salt, sugar) or specific guidance (e.g., “heart-healthy” graphics). The goal is to empower restaurant patrons with better data to make healthier choices, and ultimately to reduce obesity prevalence. PMID:23078494

    Over the last twenty years, with growing policy emphasis on improving energy efficiency and reducing environmental pollution and carbon emissions, China has implemented a series of new minimum energy performance standards (MEPS) and mandatory and voluntary energy labels to improve appliance energy efficiency. As China begins planning for the next phase of standards and labeling (S&L) program development under the 12th Five Year Plan, an evaluation of recent program developments and future directions is needed to identify gaps that still exist when compared with international best practices. The review of China’s S&L program development and implementation in comparison with major findings from international experiences reveal that there are still areas of improvement, particularly when compared to success factors observed across leading international S&L program. China currently lacks a formalized regulatory process for standard-setting and do not have any legal or regulatory guidance on elements of S&L development such as stakeholder participation or the issue of legal precedence between conflicting national, industrial and local standards. Consequently, China’s laws regarding standard-setting and management of the mandatory energy label program could be updated, as they have not been amended or revised recently and no longer reflects the current situation. While China uses similar principles for choosing target products as the U.S., Australia, EU and Japan, including high energy-consumption, mature industry and testing procedure and stakeholder support, recent MEPS revisions have generally aimed at only eliminating the bottom 20% efficiency of the market. Setting a firm principle based on maximizing energy savings that are technically feasible and economically justified may help improve the stringency of China’s MEPS program and reduce the need for frequent revisions. China also lacks robust survey data and relies primarily on market research data in

  20. Optimizing connected component labeling algorithms

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Kesheng; Otoo, Ekow; Shoshani, Arie

    2005-01-16

    This paper presents two new strategies that can be used to greatly improve the speed of connected component labeling algorithms. To assign a label to a new object, most connected component labeling algorithms use a scanning step that examines some of its neighbors. The first strategy exploits the dependencies among them to reduce the number of neighbors examined. When considering 8-connected components in a 2D image, this can reduce the number of neighbors examined from four to one in many cases. The second strategy uses an array to store the equivalence information among the labels. This replaces the pointer based rooted trees used to store the same equivalence information. It reduces the memory required and also produces consecutive final labels. Using an array instead of the pointer based rooted trees speeds up the connected component labeling algorithms by a factor of 5 {approx} 100 in our tests on random binary images.

    Full Text Available Health Check (HC was a voluntary nutrition labeling program developed by the Heart and Stroke Foundation of Canada as a guide to help consumers choose healthy foods. Items meeting nutrient criteria were identified with a HC symbol. This study examined the impact of the program on differences in consumer awareness and use of nutritional information in restaurants. Exit surveys were conducted with 1126 patrons outside four HC and four comparison restaurants in Ontario, Canada (2013. Surveys assessed participant noticing of nutrition information, influence of nutrition information on menu selection, and nutrient intake. Significantly more patrons at HC restaurants noticed nutrition information than at comparison restaurants (34.2% vs. 28.1%; OR = 1.39; p = 0.019; however, only 5% of HC restaurant patrons recalled seeing the HC symbol. HC restaurant patrons were more likely to say that their order was influenced by nutrition information (10.9% vs. 4.5%; OR = 2.96, p < 0.001; and consumed less saturated fat and carbohydrates, and more protein and fibre (p < 0.05. Approximately 15% of HC restaurant patrons ordered HC approved items; however, only 1% ordered a HC item and mentioned seeing the symbol in the restaurant in an unprompted recall task, and only 4% ordered a HC item and reported seeing the symbol on the item when asked directly. The HC program was associated with greater levels of noticing and influence of nutrition information, and more favourable nutrient intake; however, awareness of the HC program was very low and differences most likely reflect the type of restaurants that “self-selected” into the program.

  4. Comparison of Test Procedures and Energy Efficiency Criteria in Selected International Standards and Labeling Programs for Clothes Washers, Water Dispensers, Vending Machines and CFLs

    Energy Technology Data Exchange (ETDEWEB)

    Fridley, David; Zheng, Nina; Zhou, Nan

    2010-06-01

    Since the late 1970s, energy labeling programs and mandatory energy performance standards have been used in many different countries to improve the efficiency levels of major residential and commercial equipment. As more countries and regions launch programs covering a greater range of products that are traded worldwide, greater attention has been given to harmonizing the specific efficiency criteria in these programs and the test methods for measurements. For example, an international compact fluorescent light (CFL) harmonization initiative was launched in 2006 to focus on collaboration between Australia, China, Europe and North America. Given the long history of standards and labeling programs, most major energy-consuming residential appliances and commercial equipment are already covered under minimum energy performance standards (MEPS) and/or energy labels. For these products, such as clothes washers and CFLs, harmonization may still be possible when national MEPS or labeling thresholds are revised. Greater opportunity for harmonization exists in newer energy-consuming products that are not commonly regulated but are under consideration for new standards and labeling programs. This may include commercial products such as water dispensers and vending machines, which are only covered by MEPS or energy labels in a few countries or regions. As China continues to expand its appliance standards and labeling programs and revise existing standards and labels, it is important to learn from recent international experiences with efficiency criteria and test procedures for the same products. Specifically, various types of standards and labeling programs already exist in North America, Europe and throughout Asia for products in China's 2010 standards and labeling programs, namely clothes washers, water dispensers, vending machines and CFLs. This report thus examines similarities and critical differences in energy efficiency values, test procedure specifications and

    Task-based interface design principles (TBI) were evaluated as a framework for designing effective nutritional labels. In two experiments a total of 123 people assembled a packed lunch, selecting components using labels in GDA or TBI format, or when given only the names of the foods. Study 1 found that a GDA label helped people make healthier choices than the product name alone, but that for a number of types of food, most people would make the same decision with or without a GDA label. Moreover, decisions were much faster when made with the name alone. Study 2 introduced a TBI label in the context of the more specific task of keeping the salt in the lunch under 1g. TBI and GDA labels reduced salt equally, but only the TBI label was as quick as the name alone. Labels that are aligned with people's specific objectives are more efficient. TBI is a potentially useful framework, that can be deployed using mobile computing. Copyright © 2010 Elsevier Ltd. All rights reserved.

To test this proposition, the impact of a carbon footprint label......, participants saw the original Carbon Trust label and in the other condition they saw the same label, but with traffic light colors added to communicate the product’s relative performance in terms of carbon footprint. All included attributes were found to have a significant impact on consumer choices....... As expected, price and carbon footprint were negatively related to choice. Further, participants preferred organic to non-organic coffee and certification by a public authority. The effect of the carbon label is significantly stronger the more environmentally concerned the consumer is. Using colors...

    2010-06-01

    We assessed whether labeling restaurant menus with information on the nutrient content of menu items would cause customers to alter their ordering patterns. Six full-service restaurants in Pierce County, Washington, added nutrition information to their menus, and they provided data on entrée sales for 30 days before and 30 days after the information was added. We assessed the prelabeling versus postlabeling difference in nutrient content of entrées sold, and we surveyed restaurant patrons about whether they noticed the nutrition information and used it in their ordering. The average postlabeling entrée sold contained about 15 fewer calories, 1.5 fewer grams of fat, and 45 fewer milligrams of sodium than did the average entrée sold before labeling. Seventy-one percent of patrons reported noticing the nutrition information; 20.4% reported ordering an entrée lower in calories as a result, and 16.5% reported ordering an entrée lower in fat as a result. The concentration of calorie reduction among 20.4% of patrons means that each calorie-reducing patron ordered about 75 fewer calories than they did before labeling. Thus, providing nutrition information on restaurant menus may encourage a subset of restaurant patrons to significantly alter their food choices.

    2008-06-03

    ENERGY STAR is a voluntary energy efficiency-labeling program operated jointly by the United States Department of Energy and the United States Environmental Protection Agency (US EPA). Since the program inception in 1992, ENERGY STAR has become a leading international brand for energy efficient products. ENERGY STAR's central role in the development of regional, national, and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with committed stakeholders. Through 2006, US EPA?S ENERGY STAR labeled products saved 4.8 EJ of primary energy and avoided 82 Tg C equivalent. We project that US EPA?S ENERGY STAR labeled products will save 12.8 EJ and avoid 203 Tg C equivalent over the period 2007-2015. A sensitivity analysis examining two key inputs (carbon factor and ENERGY STAR unit sales) bounds the best estimate of carbon avoided between 54 Tg C and 107 Tg C (1993 to 2006) and between 132 Tg C and 278 Tg C (2007 to 2015).

    Fink, M; Haunert, Jan-Henrik; Schulz, A; Spoerhase, J; Wolff, A

    2012-12-01

    In this paper, we investigate the problem of labeling point sites in focus regions of maps or diagrams. This problem occurs, for example, when the user of a mapping service wants to see the names of restaurants or other POIs in a crowded downtown area but keep the overview over a larger area. Our approach is to place the labels at the boundary of the focus region and connect each site with its label by a linear connection, which is called a leader. In this way, we move labels from the focus region to the less valuable context region surrounding it. In order to make the leader layout well readable, we present algorithms that rule out crossings between leaders and optimize other characteristics such as total leader length and distance between labels. This yields a new variant of the boundary labeling problem, which has been studied in the literature. Other than in traditional boundary labeling, where leaders are usually schematized polylines, we focus on leaders that are either straight-line segments or Bezier curves. Further, we present algorithms that, given the sites, find a position of the focus region that optimizes the above characteristics. We also consider a variant of the problem where we have more sites than space for labels. In this situation, we assume that the sites are prioritized by the user. Alternatively, we take a new facility-location perspective which yields a clustering of the sites. We label one representative of each cluster. If the user wishes, we apply our approach to the sites within a cluster, giving details on demand.

    1994-10-01

    A convenient method is described to label a local anesthetic, benzocaine, with tritium. The bromoester of para-aminobenzoic acid (PABA) was prepared from para-nitrotoluene and was reduced with tritium. The generation of isotopic hydrogen and labelling of benzocaine was achieved in one-step. A mixture of sodium borohydride (NaB[sup 3]H[sub 4]) with cobalt (II) chloride was used to generate tritium gas. 5% Pd/C was used as a catalyst. This constitutes the first report of tritium labelled benzocaine. (author).

    In simulating radiotherapy, the bone and trachea identified by plain X-P and the other organs, such as the esophagus and bladder, outlined by contrast medium have so far been used as labels. However, irradiation with a high therapeutic ratio is required for an intracorporeal insertion of artificial labels that are identified by X-ray fluoroscopy. For this purpose, metal clips and seed dummies are available, although they cause artifacts in CT scans. Therefore, the authors are using an acupuncture needle and lipiodol for tracing as new artificial labels, since both are identified by X-ray fluoroscopy and CT scan and create few artifacts.

  10. LabeledIn: cataloging labeled indications for human drugs.

    Science.gov (United States)

    Khare, Ritu; Li, Jiao; Lu, Zhiyong

    2014-12-01

    Drug-disease treatment relationships, i.e., which drug(s) are indicated to treat which disease(s), are among the most frequently sought information in PubMed®. Such information is useful for feeding the Google Knowledge Graph, designing computational methods to predict novel drug indications, and validating clinical information in EMRs. Given the importance and utility of this information, there have been several efforts to create repositories of drugs and their indications. However, existing resources are incomplete. Furthermore, they neither label indications in a structured way nor differentiate them by drug-specific properties such as dosage form, and thus do not support computer processing or semantic interoperability. More recently, several studies have proposed automatic methods to extract structured indications from drug descriptions; however, their performance is limited by natural language challenges in disease named entity recognition and indication selection. In response, we report LabeledIn: a human-reviewed, machine-readable and source-linked catalog of labeled indications for human drugs. More specifically, we describe our semi-automatic approach to derive LabeledIn from drug descriptions through human annotations with aids from automatic methods. As the data source, we use the drug labels (or package inserts) submitted to the FDA by drug manufacturers and made available in DailyMed. Our machine-assisted human annotation workflow comprises: (i) a grouping method to remove redundancy and identify representative drug labels to be used for human annotation, (ii) an automatic method to recognize and normalize mentions of diseases in drug labels as candidate indications, and (iii) a two-round annotation workflow for human experts to judge the pre-computed candidates and deliver the final gold standard. In this study, we focused on 250 highly accessed drugs in PubMed Health, a newly developed public web resource for consumers and clinicians on prevention

  15. Positron emitter labeled enzyme inhibitors

    Science.gov (United States)

    Fowler, J.S.; MacGregor, R.R.; Wolf, A.P.

    1987-05-22

    This invention involved a new strategy for imaging and mapping enzyme activity in the living human and animal body using positron emitter-labeled suicide enzyme inactivators or inhibitors which become covalently bound to the enzyme as a result of enzymatic catalysis. Two such suicide in activators for monoamine oxidase have been labeled with carbon-11 and used to map the enzyme subtypes in the living human and animal body using PET. By using positron emission tomography to image the distribution of radioactivity produced by the body penetrating radiation emitted by carbon-11, a map of functionally active monoamine oxidase activity is obtained. Clorgyline and L-deprenyl are suicide enzyme inhibitors and irreversibly inhibit monoamine oxidase. When these inhibitors are labeled with carbon-11 they provide selective probes for monoamine oxidase localization and reactivity in vivo using positron emission tomography. 2 figs.

    1988-01-01

    Several methods for the specific deuteration of cannabinoids are described. Deuteration of the phenolic ring was accomplished by treatment with BF/sub 3/center dotEt/sub 2/O followed by quenching with a solution of Na/sub 2/ CO/sub 3/ in D/sub 2/ O resulting in deuterium incorporation in both the 2 and 4 positions. Regioselective incorporation of deuterium into either the 2 or 4 position of ..delta../sup 8/-THC was achieved using Florisil spiked with either D/sub 2/O or H/sub 2/O. Deuteration at positions 8, 10 and 11 was achieved by addition of DC1 gas to the appropriate tetrahydrocannabinol to form 9-chlorohexahydrocannabinol labeled at either of the above positions, followed by elimination of hydrogen- or deuterium chloride with potassium-tert-amylate. UV irradiation of specifically labeled ..delta../sup 8/-THC gave the correspondingly labeled ..delta..sup(9,11)-THC.

  18. Food labeling: gluten-free labeling of foods. Final rule.

    Science.gov (United States)

    2013-08-05

    The Food and Drug Administration (FDA or we) is issuing a final rule to define the term "gluten-free'' for voluntary use in the labeling of foods. The final rule defines the term "gluten-free'' to mean that the food bearing the claim does not contain an ingredient that is a gluten-containing grain (e.g., spelt wheat); an ingredient that is derived from a gluten-containing grain and that has not been processed to remove gluten (e.g., wheat flour); or an ingredient that is derived from a gluten-containing grain and that has been processed to remove gluten (e.g., wheat starch), if the use of that ingredient results in the presence of 20 parts per million (ppm) or more gluten in the food (i.e., 20 milligrams (mg) or more gluten per kilogram (kg) of food); or inherently does not contain gluten; and that any unavoidable presence of gluten in the food is below 20 ppm gluten (i.e., below 20 mg gluten per kg of food). A food that bears the claim "no gluten,'' "free of gluten,'' or "without gluten'' in its labeling and fails to meet the requirements for a "gluten-free'' claim will be deemed to be misbranded. In addition, a food whose labeling includes the term "wheat'' in the ingredient list or in a separate "Contains wheat'' statement as required by a section of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) and also bears the claim "gluten-free'' will be deemed to be misbranded unless its labeling also bears additional language clarifying that the wheat has been processed to allow the food to meet FDA requirements for a "gluten-free'' claim. Establishing a definition of the term "gluten-free'' and uniform conditions for its use in food labeling will help ensure that individuals with celiac disease are not misled and are provided with truthful and accurate information with respect to foods so labeled. We are issuing the final rule under the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA).

  1. Nutrition marketing on processed food packages in Canada: 2010 Food Label Information Program.

    Science.gov (United States)

    Schermel, Alyssa; Emrich, Teri E; Arcand, JoAnne; Wong, Christina L; L'Abbé, Mary R

    2013-06-01

    The current study describes the frequency of use of different forms of nutrition marketing in Canada and the nutrients and conditions that are the focus of nutrition marketing messages. Prepackaged foods with a Nutrition Facts table (N = 10,487) were collected between March 2010 and April 2011 from outlets of the 3 largest grocery chains in Canada and 1 major western Canadian grocery retailer. The nutrition marketing information collected included nutrient content claims, disease risk reduction claims, and front-of-pack nutrition rating systems (FOPS). We found that nutrition marketing was present on 48.1% of Canadian food packages, with nutrient content claims being the most common information (45.5%), followed by FOPS on 18.9% of packages. Disease risk reduction claims were made least frequently (1.7%). The marketing messages used most often related to total fat and trans fat (15.6% and 15.5% of nutrient content claims, respectively). Limiting total and trans fats is a current public health priority, as recommended by Health Canada and the World Health Organization. However, other nutrients that are also recommended to be limited, including saturated fats, sodium, and added sugars, were not nearly as prominent on food labels. Thus, greater emphasis should be placed by the food industry on these other important nutrients. Repeated data collection in the coming years will allow us to track longitudinal changes in nutrition marketing messages over time as food marketing, public health, and consumer priorities evolve.

  11. Predicting protein functions using incomplete hierarchical labels.

    Science.gov (United States)

    Yu, Guoxian; Zhu, Hailong; Domeniconi, Carlotta

    2015-01-16

    Protein function prediction is to assign biological or biochemical functions to proteins, and it is a challenging computational problem characterized by several factors: (1) the number of function labels (annotations) is large; (2) a protein may be associated with multiple labels; (3) the function labels are structured in a hierarchy; and (4) the labels are incomplete. Current predictive models often assume that the labels of the labeled proteins are complete, i.e. no label is missing. But in real scenarios, we may be aware of only some hierarchical labels of a protein, and we may not know whether additional ones are actually present. The scenario of incomplete hierarchical labels, a challenging and practical problem, is seldom studied in protein function prediction. In this paper, we propose an algorithm to Predict protein functions using Incomplete hierarchical LabeLs (PILL in short). PILL takes into account the hierarchical and the flat taxonomy similarity between function labels, and defines a Combined Similarity (ComSim) to measure the correlation between labels. PILL estimates the missing labels for a protein based on ComSim and the known labels of the protein, and uses a regularization to exploit the interactions between proteins for function prediction. PILL is shown to outperform other related techniques in replenishing the missing labels and in predicting the functions of completely unlabeled proteins on publicly available PPI datasets annotated with MIPS Functional Catalogue and Gene Ontology labels. The empirical study shows that it is important to consider the incomplete annotation for protein function prediction. The proposed method (PILL) can serve as a valuable tool for protein function prediction using incomplete labels. The Matlab code of PILL is available upon request.

  12. The labeling debate in the United States.

    Science.gov (United States)

    Marchant, Gary E; Cardineau, Guy A

    2013-01-01

    The mandatory labeling of genetically modified (GM) food has become the predominant policy issue concerning biotechnology in the United States. The controversy over GM labeling is being debated at several different levels and branches of government. At the federal level, the Food and Drug Administration, which has primary jurisdiction over food safety and labeling, has steadfastly refused to require labeling of GM foods since 1992 based on its conclusion that GM foods as a category present no unique or higher risks than other foods. Proposed legislation has been repeatedly introduced in the US. Congress over the years to mandate GM labeling, but has made very little progress. With federal labeling requirements apparently stalled, the main activity has switched to the state level, where numerous individual states are considering mandatory GM labeling, either through legislation or proposition. The debate over GM labeling, at both the federal and state levels, has focused on five issues: (1) public opinion; (2) the legality of labeling requirements; (3) the risks and benefits of GM foods; (4) the costs and burdens of GM labeling; and (5) consumer choice. While the pro-labeling forces argue that all of these factors weigh in favor of mandatory GM labeling, a more careful evaluation of the evidence finds that all five factors weigh decisively against mandatory GM labeling requirements.

    To examine knowledge of sugar recommendations and test the efficacy of formats for labeling total and added sugar on pre-packaged foods. Online surveys were conducted among 2008 Canadians aged 16-24. Participants were asked to identify recommended limits for total and added sugar consumption. In Experiment 1, participants were randomized to one of six labeling conditions with varying information for total sugar for a high- or low-sugar product and were asked to identify the relative amount of total sugar in the product. In Experiment 2, participants were randomized to one of three labels with different added sugar formats and were asked if the product contained added sugar and the relative amount of added sugar. Few young people correctly identified recommendations for total sugar (5%) or added sugar (7%). In Experiment 1, those who were shown percent daily value information were more likely to correctly identify the relative amount of total sugar (P sugar information were more likely to correctly identify that the product contained added sugar and the relative amount of added sugar in the product (P sugars in food products. © 2015 The Obesity Society.

  7. 99mTc: Labeling Chemistry and Labeled Compounds

    Science.gov (United States)

    Alberto, R.; Abram, U.

    This chapter reviews the radiopharmaceutical chemistry of technetium related to the synthesis of perfusion agents and to the labeling of receptor-binding biomolecules. To understand the limitations of technetium chemistry imposed by future application of the complexes in nuclear medicine, an introductory section analyzes the compulsory requirements to be considered when facing the incentive of introducing a novel radiopharmaceutical into the market. Requirements from chemistry, routine application, and market are discussed. In a subsequent section, commercially available 99mTc-based radiopharmaceuticals are treated. It covers the complexes in use for imaging the most important target organs such as heart, brain, or kidney. The commercially available radiopharmaceuticals fulfill the requirements outlined earlier and are discussed with this background. In a following section, the properties and perspectives of the different generations of radiopharmaceuticals are described in a general way, covering characteristics for perfusion agents and for receptor-specific molecules. Technetium chemistry for the synthesis of perfusion agents and the different labeling approaches for target-specific biomolecules are summarized. The review comprises a general introduction to the common approaches currently in use, employing the N x S4-x , [3+1] and 2-hydrazino-nicotinicacid (HYNIC) method as well as more recent strategies such as the carbonyl and the TcN approach. Direct labeling without the need of a bifunctional chelator is briefly reviewed as well. More particularly, recent developments in the labeling of concrete targeting molecules, the second generation of radiopharmaceuticals, is then discussed and prominent examples with antibodies/peptides, neuroreceptor targeting small molecules, myocardial imaging agents, vitamins, thymidine, and complexes relevant to multidrug resistance are given. In addition, a new approach toward peptide drug development is described. The section

  9. Do nutrition labels improve dietary outcomes?

    Science.gov (United States)

    Variyam, Jayachandran N

    2008-06-01

    The disclosure of nutritional characteristics of most packaged foods became mandatory in the United States with the implementation of the Nutrition Labeling and Education Act (NLEA) in 1994. Under the NLEA regulations, a 'Nutrition Facts' panel displays information on nutrients such as calories, total and saturated fats, cholesterol, and sodium in a standardized format. By providing nutrition information in a credible, distinctive, and easy-to-read format, the new label was expected to help consumers choose healthier, more nutritious diets. This paper examines whether the disclosure of nutrition information through the mandatory labels impacted consumer diets. Assessing the dietary effects of labeling is problematic due to the confounding of the label effect with unobserved label user characteristics. This self-selection problem is addressed by exploiting the fact that the NLEA exempts away-from-home foods from mandatory labeling. Difference-in-differences models that account for zero away-from-home intakes suggest that the labels increase fiber and iron intakes of label users compared with label nonusers. In comparison, a model that does not account for self-selection implies significant label effects for all but two of the 13 nutrients that are listed on the label.

    Earlier research has identified consumer characteristics associated with viewing Nutrition Facts labels; however, little is known about those who view front-of-package nutrition labels. Front-of-package nutrition labels might appeal to more consumers than do Nutrition Facts labels, but it might be necessary to provide consumers with information about how to locate and use these labels. This study quantifies Nutrition Facts and front-of-package nutrition label viewing among American adult consumers. Attention to nutrition information was measured during a food-selection task. One hundred and twenty-three parents (mean age=38 years, mean body mass index [calculated as kg/m(2)]=28) and one of their children (aged 6 to 9 years) selected six foods from a university laboratory-turned-grocery aisle. Participants were randomized to conditions in which front-of-package nutrition labels were present or absent, and signage explaining front-of-package nutrition labels was present or absent. Adults' visual attention to Nutrition Facts labels and front-of-package nutrition labels was objectively measured via eye-tracking glasses. To examine whether there were significant differences in the percentages of participants who viewed Nutrition Facts labels vs front-of-package nutrition labels, McNemar's tests were conducted across all participants, as well as within various sociodemographic categories. To determine whether hypothesized factors, such as health literacy and education, had stronger relationships with front-of-package nutrition label vs Nutrition Facts label viewing, linear regression assessed the magnitude of relationships between theoretically and empirically derived factors and each type of label viewing. Overall, front-of-package nutrition labels were more likely to be viewed than Nutrition Facts labels; however, for all subgroups, higher rates of front-of-package nutrition label viewership occurred only when signage was present drawing attention to the presence and

    2015-11-01

    We examine a key modified labeling theory proposition-that a psychiatric label increases vulnerability to competence-based criticism and rejection-within task- and collectively oriented dyads comprised of same-sex individuals with equivalent education. Drawing on empirical work that approximates these conditions, we expect the proposition to hold only among men. We also expect education, operationalized with college class standing, to moderate the effects of gender by reducing men's and increasing women's criticism and rejection. But, we also expect the effect of education to weaken when men work with a psychiatric patient. As predicted, men reject suggestions from teammates with a psychiatric history more frequently than they reject suggestions from other teammates, while women's resistance to influence is unaffected by their teammate's psychiatric status. Men also rate psychiatric patient teammates as less powerful but no lower in status than other teammates, while women's teammate assessments are unaffected by their teammate's psychiatric status. Also as predicted, education reduces men's resistance to influence when their teammate has no psychiatric history. Education also increases men's ratings of their teammate's power, as predicted, but has no effect on women's resistance to influence or teammate ratings. We discuss the implications of these findings for the modified labeling theory of mental illness and status characteristics theory. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. Stigma of a label: educational expectations for high school students labeled with learning disabilities.

    2013-01-01

    Poorer outcomes for youth labeled with learning disabilities (LDs) are often attributed to the student's own deficiencies or cumulative disadvantage; but the more troubling possibility is that special education placement limits rather than expands these students' opportunities. Labeling theory partially attributes the poorer outcomes of labeled persons to stigma related to labels. This study uses data on approximately 11,740 adolescents and their schools from the Education Longitudinal Survey of 2002 to determine if stigma influences teachers' and parents' educational expectations for students labeled with LDs and labeled adolescents' expectations for themselves. Supporting the predictions of labeling theory, teachers and parents are more likely to perceive disabilities in, and hold lower educational expectations for labeled adolescents than for similarly achieving and behaving adolescents not labeled with disabilities. The negative effect of being labeled with LDs on adolescents' educational expectations is partially mechanized through parents' and particularly teachers' lower expectations.

    The Food and Drug Administration (FDA or the Agency) is issuing this final rule revising its medical device and certain biological product labeling regulations to explicitly allow for the optional inclusion of graphical representations of information, or symbols, in labeling (including labels) without adjacent explanatory text (referred to in this document as "stand-alone symbols") if certain requirements are met. The final rule also specifies that the use of symbols, accompanied by adjacent explanatory text continues to be permitted. FDA is also revising its prescription device labeling regulations to allow the use of the symbol statement "Rx only" or "[rx] only" in the labeling for prescription devices.

    2017-02-01

    Once a drug has been approved by the United States Food and Drug Administration and is on the market, the Food and Drug Administration communicates new safety information through product label changes. Most of these label changes occur after a spontaneous report to either the drug manufacturing companies or the Food and Drug Administration MedWatch program. As a result, 400 to 500 label changes occur every year. Actinic keratosis treatments exemplify the commonality of label changes throughout the postmarket course of a drug. Diclofenac gel, 5-fluorouracil cream, imiquimod, and ingenol mebutate are examples of actinic keratosis treatments that have all undergone at least one label revision. With the current system of spontaneous reports leading to numerous label changes, each occurrence does not necessarily signify a radical change in the safety of a drug.

  16. Link Label Prediction in Signed Citation Network

    KAUST Repository

    Akujuobi, Uchenna

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

    Optical microscopy technology has achieved great improvements in the 20th century. The detection limit has reached about twenty nanometers (with near-field optics, STED, PALM and STORM). But in the application areas such as life science, medical science, clinical treatment and especially in vivo dynamic measurement, mutual restrictions still exist between numeric aperture/magnification and working distance, fluorescent dependent, and between resolution and frame rate/field size, etc. This paper explores a hyperspectral scanning super-resolution label free molecules imaging method based on the white light interferometry. The vertical detection resolution was approximate to 1 nm which is the thickness of a single molecular layer and dynamic measuring range of thickness reaches to 10 μm. The spectrum-shifting algorithm is developed for robust restructure of images when the pixels are overlapped. Micro-biochip with protein binding and DNA amplification could be detected by using this spectral scanning super-resolution molecules imaging in label free. This method has several advantages as following: Firstly, the decoding and detecting steps are combined into one step. It makes tests faster and easier. Secondly, we used thickness-coded, minimized chips instead of a large microarray chip to carry the probes. This accelerates the interaction of the biomolecules. Thirdly, since only one kind of probes are attached to our thickness-coded, minimized chip, users can only pick out the probes they are interested in for a test without wasting unnecessary probes and chips.

  18. Matching isotopic distributions from metabolically labeled samples.

    2008-07-01

    In recent years stable isotopic labeling has become a standard approach for quantitative proteomic analyses. Among the many available isotopic labeling strategies, metabolic labeling is attractive for the excellent internal control it provides. However, analysis of data from metabolic labeling experiments can be complicated because the spacing between labeled and unlabeled forms of each peptide depends on its sequence, and is thus variable from analyte to analyte. As a result, one generally needs to know the sequence of a peptide to identify its matching isotopic distributions in an automated fashion. In some experimental situations it would be necessary or desirable to match pairs of labeled and unlabeled peaks from peptides of unknown sequence. This article addresses this largely overlooked problem in the analysis of quantitative mass spectrometry data by presenting an algorithm that not only identifies isotopic distributions within a mass spectrum, but also annotates matches between natural abundance light isotopic distributions and their metabolically labeled counterparts. This algorithm is designed in two stages: first we annotate the isotopic peaks using a modified version of the IDM algorithm described last year; then we use a probabilistic classifier that is supplemented by dynamic programming to find the metabolically labeled matched isotopic pairs. Such a method is needed for high-throughput quantitative proteomic metabolomic experiments measured via mass spectrometry. The primary result of this article is that the dynamic programming approach performs well given perfect isotopic distribution annotations. Our algorithm achieves a true positive rate of 99% and a false positive rate of 1% using perfect isotopic distribution annotations. When the isotopic distributions are annotated given 'expert' selected peaks, the same algorithm gets a true positive rate of 77% and a false positive rate of 1%. Finally, when annotating using machine selected peaks, which

  19. Neuroanatomical labeling with biocytin: a review.

    Science.gov (United States)

    McDonald, A J

    1992-10-01

    Recent studies have shown that biocytin may have multiple applications in neuroanatomical studies. Biocytin may be injected into the brain by iontophoresis or by pressure injection methods, and localized in tissue sections using avidin-conjugated labels. It is taken up by neurons and rapidly transported down axons in an anterograde fashion. Axons are completely labeled in a Golgi-like manner and can be examined at both light and electron microscopic levels. Biocytin can also be used in retrograde tract tracing experiments, although in some cases it appears that fibers must be damaged to produce such labeling. Retrogradely labeled cells may be completely labeled, resembling neurons stained with the Golgi technique. Individual neurons can also be labeled in a Golgi-like manner by uptake of biocytin from the extracellular space. Thus, it appears that biocytin is an especially versatile marker for neuroanatomical investigations.

    A method for the production of carboxy-labelled l-carnitine is described. The first step is the chemical synthesis of 4-N-trimethylammoniobutanoate (butyrobetaine) from the precursors 4-aminobutanoate and iodomethane. The second step involves the hydroxylation of butyrobetaine to form l-carnitine using butyrobetaine hydroxylase partially purified from bovine calf liver. The method also can be used to synthesize Me-labelled and uniformly-chain-labelled l-carnitine.

  4. ML-MG: Multi-label Learning with Missing Labels Using a Mixed Graph

    KAUST Repository

    Wu, Baoyuan

    2015-12-07

    This work focuses on the problem of multi-label learning with missing labels (MLML), which aims to label each test instance with multiple class labels given training instances that have an incomplete/partial set of these labels (i.e. some of their labels are missing). To handle missing labels, we propose a unified model of label dependencies by constructing a mixed graph, which jointly incorporates (i) instance-level similarity and class co-occurrence as undirected edges and (ii) semantic label hierarchy as directed edges. Unlike most MLML methods, We formulate this learning problem transductively as a convex quadratic matrix optimization problem that encourages training label consistency and encodes both types of label dependencies (i.e. undirected and directed edges) using quadratic terms and hard linear constraints. The alternating direction method of multipliers (ADMM) can be used to exactly and efficiently solve this problem. To evaluate our proposed method, we consider two popular applications (image and video annotation), where the label hierarchy can be derived from Wordnet. Experimental results show that our method achieves a significant improvement over state-of-the-art methods in performance and robustness to missing labels.

    Human platelets were labelled in the absence of presence of plasma using {sup 111}In-labelled oxine sulphate, tropolone or 2-mercaptopyridine-N-oxide (MPO). Under in vitro and in vivo conditions, platelet functions were evaluated by measuring their aggregability, survival, recovery and early distribution. High labelling efficiency was achieved in saline labelling, whereas with plasma labelling, it was necessary to concentrate the platelet-rich plasma to 4.8x10{sup 6} platelets/{mu}l. The aggregation of platelets labelled in plasma or saline was compared with that of controls; platelets labelled in saline showed lower aggregability in 2 {mu}M ADP but not in 5 {mu}M ADP nor with collagen. No significant differences in platelet survival and recovery were noted between platelets labelled in plasma and those labelled in saline. Our results indicate that partial loss of ADP aggregability in vitro does not influence the in vivo viability of platelets labelled in saline. Scintigraphic studies showed that platelets labelled in a saline medium were temporarily sequestrated in the liver but not in the spleen or heart. Thus, platelet labelling in saline does not affect platelet function adversely, but platelets labelled in plasma are more desirable for assessing the early distribution of platelets in the reticuloendothelial system.

    Although the Nutrition Facts label has been a requirement on food packages for more than 20 years, few studies have conducted comprehensive assessments of food label use. The purpose of this study was to assess the demographic and psychosocial correlates of food label use using a comprehensive approach. A sample of 1,382 males and females (n=573 and n=809, respectively) aged 19 to 70 years was drawn from the 2005-2006 National Health and Nutrition Examination Survey. The food label Check and Use subscales are the sums of multiple questions on frequency of checking and using each separate component on a Nutrition Facts label. Multiple linear regression was used to assess differences in predictors of Check and Use. Determinants of food label use differed by sex. Women check and use food label components more often and thoroughly than men. Older adults and adults with good diet-quality perception were significant predictors of food label use for both men and women. Race was a significant predictor for men only. Mexican-American and other Hispanic groups check (P=0.03) and use (P=0.01) the food label more frequently than non-Hispanic white men. Men who do not receive Supplemental Nutrition Assistance Program benefits also check (Pfood labels more frequently than those who receive assistance. The findings of this study could be used to improve nutrition education efforts. It may be beneficial to target men and women separately, as food label use determinants are different.

  9. Photoactivated In Vivo Proximity Labeling.

    Beck, David B; Bonasio, Roberto

    2017-06-19

    Identification of molecular interactions is paramount to understanding how cells function. Most available technologies rely on co-purification of a protein of interest and its binding partners. Therefore, they are limited in their ability to detect low-affinity interactions and cannot be applied to proteins that localize to difficult-to-solubilize cellular compartments. In vivo proximity labeling (IPL) overcomes these obstacles by covalently tagging proteins and RNAs based on their proximity in vivo to a protein of interest. In IPL, a heterobifunctional probe comprising a photoactivatable moiety and biotin is recruited by a monomeric streptavidin tag fused to a protein of interest. Following UV irradiation, candidate interacting proteins and RNAs are covalently biotinylated with tight spatial and temporal control and subsequently recovered using biotin as an affinity handle. Here, we describe experimental protocols to discover novel protein-protein and protein-RNA interactions using IPL. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley & Sons, Inc.

  11. F-18 labeled 3-fluorodiazepam

    Energy Technology Data Exchange (ETDEWEB)

    Luxen, A.; Barrio, J.R.; Bida, G.T.; Satyamurthy, N.; Phelps, M.E.

    1985-05-01

    3-Fluorodiazepam is a new and potent antianxiety agent with prolonged action. The authors found that molecular fluorine (0.5% in Ne) reacts cleanly with diazepam in freon or chloroform at room temperature to produce 3-fluorodiazepam in good yields. Successful syntheses have employed 2:1 to 5:1 molar ratios diazepam: fluorine to minimize the formation of byproducts. (/sup 18/F) 3-Fluorodiazepam, a potential candidate for PET studies, (specific activity 3-5 Ci/mmol) has been synthesized from /sup 18/F-F/sub 2/ using the same procedure, followed by column chromatographic purification (Silicagel, dichloromethane: ethyl acetate, 5:1) with a radiochemical yield of 12-20% (50% maximum) and a chemical and radiochemical purity >99% as judged by reversed-phase high pressure liquid chromatography analysis (Ultrasyl octyl column, 10 ..mu.. m, 4.6 x 250 mm i.d., 60% MeOH 40% water; flow rate, 1.0 ml/min; retention time for (/sup 18/F) fluorodiazepam, 11.4 min; for diazepam, 13.5 min; radioactivity and ultraviolet detectors). Lower radiochemical yields (5-7%), and significant formation of by-products were observed when (/sup 18/F)acetylhypofluorite, prepared in the gasphase, was used as the reagent. Readily accessible routes to /sup 18/F-labeled benzodiazepines of higher specific activity were also investigated. Approaches to the synthesis of high specific activity (>200 Ci/mmol) (/sup 18/F)3-fluorodiazepam involve nucleophilic displacement at carbon-3 (e.g. from 3-chlorodiazepam) with (/sup 18/F)fluoride ion. The results presented here demonstrate the synthetic accessibility of /sup 18/F-labeled benzodiazepines for application in neurotransmitter ligand studies with PET.

  12. Chain store management through private labels strategy

    Directory of Open Access Journals (Sweden)

    Martina Sopta

    2007-07-01

    Full Text Available The purpose of this paper is to examine the market shares of private labels in the European Union and on the global market, and to compare the results of the analysis with the level of presence of private labels on the Croatian market. Moreover, through the application of macro and microeconomic tools, the author tried to estimate the future trends of private labels in Croatia.For the purpose of the paper secondary and primary data was used in the research. Relevant scientific and professional literature of local and foreign authors was analyzed. In addition, a few recent research studies were analyzed and their results compared. Field research has been conducted by the survey method, with 225 respondents included in the intentional sample.The main hypothesis of the paper based on research is that, in total sales, private labels are gaining a growing share in all markets, regardless of the development level of those markets. Alongside the main hypothesis of the work, three supporting hypotheses were tested to see which private labels are a good alternative to other brands on the world market. Private labels are generally developed on generic products. The third supporting hypothesis starts from the assumption that the investments in the promotion of private labels are negligible, resulting in lower prices of thoseproducts. The results of research and analyses in the work indicate that the position of private labels will strengthen internationally, as part of the process of liberalization and globalization of trade flows. In the process of purchase of private labels the positioning of the point of sale and price have an increasing contribution. With the concentration of commerce in chain stores, the share of private labels grows, approaching a half of the total sales in some countries. Considering the Croatian market, according to the international product life cycle theory, the share of private labels in the total sales will grow in the future

  9. Handicap Labelings of 4-Regular Graphs

    Directory of Open Access Journals (Sweden)

    Petr Kovar

    2017-01-01

    Full Text Available Let G be a simple graph, let f : V(G→{1,2,...,|V(G|} be a bijective mapping. The weight of v ∈ V(G is the sum of labels of all vertices adjacent to v. We say that f is a distance magic labeling of G if the weight of every vertex is the same constant k and we say that f is a handicap magic labeling of G if the weight of every vertex v is l + f(v for some constant l. Graphs that allow such labelings are called distance magic or handicap, respectively. Distance magic and handicap labelings of regular graphs are used for scheduling incomplete tournaments. While distance magic labelings correspond to so called equalized tournaments, handicap labelings can be used to schedule incomplete tournaments that are more challenging to stronger teams or players, hence they increase competition and yield attractive schemes in which every games counts. We summarize known results on distance magic and handicap labelings and construct a new infinite class of 4-regular handicap graphs.

    Image segmentation plays a crucial role in many medical imaging applications by automatically locating the regions of interest. Typically supervised learning based segmentation methods require a large set of accurately labeled training data. However, thel labeling process is tedious, time consuming and sometimes not necessary. We propose a robust logistic regression algorithm to handle label outliers such that doctors do not need to waste time on precisely labeling images for training set. To validate its effectiveness and efficiency, we conduct carefully designed experiments on cervigram image segmentation while there exist label outliers. Experimental results show that the proposed robust logistic regression algorithms achieve superior performance compared to previous methods, which validates the benefits of the proposed algorithms.

  1. ALE: automated label extraction from GEO metadata.

    Giles, Cory B; Brown, Chase A; Ripperger, Michael; Dennis, Zane; Roopnarinesingh, Xiavan; Porter, Hunter; Perz, Aleksandra; Wren, Jonathan D

    2017-12-28

    NCBI's Gene Expression Omnibus (GEO) is a rich community resource containing millions of gene expression experiments from human, mouse, rat, and other model organisms. However, information about each experiment (metadata) is in the format of an open-ended, non-standardized textual description provided by the depositor. Thus, classification of experiments for meta-analysis by factors such as gender, age of the sample donor, and tissue of origin is not feasible without assigning labels to the experiments. Automated approaches are preferable for this, primarily because of the size and volume of the data to be processed, but also because it ensures standardization and consistency. While some of these labels can be extracted directly from the textual metadata, many of the data available do not contain explicit text informing the researcher about the age and gender of the subjects with the study. To bridge this gap, machine-learning methods can be trained to use the gene expression patterns associated with the text-derived labels to refine label-prediction confidence. Our analysis shows only 26% of metadata text contains information about gender and 21% about age. In order to ameliorate the lack of available labels for these data sets, we first extract labels from the textual metadata for each GEO RNA dataset and evaluate the performance against a gold standard of manually curated labels. We then use machine-learning methods to predict labels, based upon gene expression of the samples and compare this to the text-based method. Here we present an automated method to extract labels for age, gender, and tissue from textual metadata and GEO data using both a heuristic approach as well as machine learning. We show the two methods together improve accuracy of label assignment to GEO samples.

  2. Does the Drug Facts Label for nonprescription drugs meet its design objectives? A new procedure for assessing label effectiveness

    Directory of Open Access Journals (Sweden)

    Michael P Ryan

    2017-07-01

    Full Text Available We demonstrate an expanded procedure for assessing drug-label comprehension. Innovations include a pretest of drug preconceptions, verbal ability and label attentiveness measures, a label-scanning task, a free-recall test, category-clustering measures, and preconception-change scores. In total, 55 female and 39 male undergraduates read a facsimile Drug Facts Label for aspirin, a Cohesive-Prose Label, or a Scrambled-Prose Label. The Drug Facts Label outperformed the Scrambled-Prose Label, but not the Cohesive-Prose Label, in scanning effectiveness. The Drug Facts Label was no better than the Cohesive-Prose Label or the Scrambled-Prose Label in promoting attentiveness, recall and organization of drug facts, or misconception refutation. Discussion focuses on the need for refutational labels based on a sequence-of-events text schema.

    2011-04-01

    Full Text Available In the rush to produce more and more crops to satisfy growing demand producers have had to resort to using a lethal cocktail of pesticides to control disease and insect attack. This has lead to numerous international debates about unhealthy food, the effects of it and the measures that must be taken in order to avoid the harmful effects of genetically modified food consumption demonstrated by specialists. These debates evolve around the benefits of the organic products versus the pure trade trick outlined by some. The organic food movement has earned its well deserved place in many markets around the world. Its prestige is lately being widespread to vast parts of Eastern-Europe as well. Based on data collected from specialized reports and articles on organic products, the aim of this paper is to present the importance of organic products, the regulations on organic food and different labels used around the world in order to certify the organic food products.

    Sparrow, J T; Patel, K M; Morrisett, J D

    1983-07-01

    The synthesis of tetradecanoic acid enriched with 13C at carbons 1, 3, or 6 is described. The label at the carbonyl carbon was introduced by treating 1-bromotridecane with K13CN (90% enriched) to form the 13C-labeled nitrile, which upon hydrolysis yielded the desired acid. The [3-13C]tetradecanoic acid was synthesized by alkylation of diethyl sodio-malonate with [1-13C]1-bromododecane; the acid was obtained upon saponification and decarboxylation. The label at the 6 position was introduced by coupling the appropriately labeled alkylcadmium chloride with the half acid chloride methyl ester of the appropriate dioic acid, giving the corresponding oxo fatty acid ester. Formation of the tosylhydrazone of the oxo-ester followed by reduction with sodium cyanoborohydride gave the labeled methyl tetradecanoate which, upon hydrolysis, yielded the desired tetradecanoic acid. All tetradecanoic acids were identical to unlabeled analogs as evaluated by gas-liquid chromatography and infrared or NMR spectroscopy. These labeled fatty acids were used subsequently to prepare the correspondingly labeled diacyl phosphatidylcholines.

    2017-01-01

    Food allergen labeling is an important tool to reduce risk of exposure and prevent anaphylaxis for individuals with food allergies. Health Canada released a Canadian food allergen labeling regulation (2008) and subsequent update (2012) suggesting that research is needed to guide further iterations of the regulation to improve food allergen labeling and reduce risk of exposure. The primary objective of this study was to examine consumer preferences in food labeling for allergy avoidance and anaphylaxis prevention. A secondary objective was to identify whether different subgroups within the consumer population emerged. A discrete choice experiment using a fractional factorial design divided into ten different versions with 18 choice-sets per version was developed to examine consumer preferences for different attributes of food labeling. Three distinct subgroups of Canadian consumers with different allergen considerations and food allergen labeling needs were identified. Overall, preferences for standardized precautionary and safety symbols at little or no increased cost emerged. While three distinct groups with different preferences were identified, in general the results revealed that the current Canadian food allergen labeling regulation can be improved by enforcing the use of standardized precautionary and safety symbols and educating the public on the use of these symbols.

  12. Labelling of food: A challenge for many

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Background: In food marketing, there is a trend towards artisanal, traditional “honest” food, and simultaneously to good looking, long lasting, multi-purpose food with a clean label. In addition, marketeers like to upgrade the image of the food, including the label, using various digital techniques. This can produce (unintended non-conformities with the current food law on labelling, which in this review, refers to Regulation (EU No 1169/2011 (European Union, 2011. Food and meat labelling have been subjected to increased regulation in the recent years, sometimes after scandals (horse-gate, food fraud, sometimes due to wishes of consumer organisations (nutritional information and sometimes after the introduction of new types of ingredients (sweeteners, phytosterols, nanomaterials. Scope and approach: This review provides information about food labelling. Some experiences gathered by food inspectorate personnel in practice, with reference to the literature data, positive aspects, main problems and trends are discussed. Key findings and conclusion: Food labelling is a complex requirement, with the general demands written down in the harmonized regulation (European Union, 2011. Foods sold by e-commerce must also follow these same regulations. However, many food labels on the market show smaller and/or bigger deviations from the legal requirements, which should be appropriately addressed by the food manufacturers or packers, but also by the competent authorities. Even training of consumers seems to be needed, since all this information is, in the end, intended for consumers to aptly utilise.

    Although the science of blood cell labeling using monoclonal antibodies directed against specific cellular antigens is still in its early stages, considerable progress has recently been accomplished in this area. The monoclonal antibody approach offers the promise of greater selectivity and enhanced convenience since specific cell types can be labeled in vivo, thus eliminating the need for complex and damaging cell separation procedures. This article focuses on these developments with primary emphasis on antibody labeling of platelets and leukocytes. The advantages and the shortcomings of the recently reported techniques are criticality assessed and evaluated.

    NMR is a powerful method for studying proteins and nucleic acids in solution. The study of nucleic acids by NMR is far more challenging than for proteins, which is mainly due to the limited number of building blocks and unfavorable spectral properties. For NMR studies of DNA molecules, (site specific) isotope enrichment is required to facilitate specific NMR experiments and applications. Here, we provide a comprehensive review of isotope-labeling strategies for obtaining stable isotope labeled DNA as well as specifically stable isotope labeled building blocks required for enzymatic DNA synthesis.

  17. Extending Modal Transition Systems with Structured Labels

    DEFF Research Database (Denmark)

    Bauer, Sebastian S.; Juhl, Line; Larsen, Kim Guldstrand

    2012-01-01

    We introduce a novel formalism of label-structured modal transition systems that combines the classical may/must modalities on transitions with structured labels that represent quantitative aspects of the model. On the one hand, the specification formalism is general enough to include models like...... weighted modal transition systems and allows the system developers to employ more complex label refinement than in the previously studied theories. On the other hand, the formalism maintains the desirable properties required by any specification theory supporting compositional reasoning. In particular, we...

  18. The antibody approach of labeling blood cells

    Energy Technology Data Exchange (ETDEWEB)

    Srivastava, S.C.

    1992-12-31

    Although the science of blood cell labeling using monoclonal antibodies directed against specific cellular antigens is still in its early stages, considerable progress has recently been accomplished in this area. The monoclonal antibody approach offers the promise of greater selectivity and enhanced convenience since specific cell types can be labeled in vivo, thus eliminating the need for complex and damaging cell separation procedures. This article focuses on these developments with primary emphasis on antibody labeling of platelets and leukocytes. The advantages and the shortcomings of the recently reported techniques are critically assessed and evaluated.

  19. Function Labeling for Unparsed Chinese Text

    Science.gov (United States)

    Yuan, Caixia; Ren, Fuji; Wang, Xiaojie; Zhong, Yixin

    This paper presents a work of function labeling for unparsed Chinese text. Unlike other attempts that utilize the full parse trees, we propose an effective way to recognize function labels directly based on lexical information, which is easily scalable for languages that lack sufficient parsing resources. Furthermore, we investigate a general method to iteratively simplify a sentence, thus transferring complicated sentence into structurally simple pieces. By means of a sequence learning model with hidden Markov support vector machine, we achieve the best F-measure of 87.40 on the text from Penn Chinese Treebank resources - a statistically significant improvement over the existing Chinese function labeling systems.

  20. On CPHD filters with track labeling

    Science.gov (United States)

    Mahler, Ronald

    2017-05-01

    The random infinite set (RFS) approach to information fusion addressed target track-labeling from the outset. The first implementations of RFS filters did not do so because of computational concerns, whereas subsequent implementations employed heuristics. The labeled RFS (LRFS) theory of B.-T. Vo and B.-N. Vo was the first systematic, theoretically rigorous formulation of true multitarget tracking; and led to the generalized labeled multi-Bernoulli (GLMB) filter (the first provably Bayes-optimal multitarget tracking algorithm). This paper addresses the feasibility of theoretically rigorous cardinalized probability hypothesis density (CPHD) filters. We show that an approximation of the GLMB filter, known as the LMB filter, can be reinterpreted as a theoretically rigorous labeled PHD (LPHD) filter. We also prove two characterization theorems for the probability generating functionals (p.g.fl's) of LRFS's.

  7. Generating Realistic Labelled, Weighted Random Graphs

    CERN Document Server

    Davis, Michael Charles; Liu, Weiru; Miller, Paul; Hunter, Ruth; Kee, Frank

    2015-01-01

    Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs) with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI) approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs). Our results allow us to draw conclusions about the contribution of vertex labels a...

  8. Food label accuracy of common snack foods.

    Jumpertz, Reiner; Venti, Colleen A; Le, Duc Son; Michaels, Jennifer; Parrington, Shannon; Krakoff, Jonathan; Votruba, Susanne

    2013-01-01

    Nutrition labels have raised awareness of the energetic value of foods, and represent for many a pivotal guideline to regulate food intake. However, recent data have created doubts on label accuracy. We tested label accuracy for energy and macronutrient content of prepackaged energy-dense snack food products. We measured "true" caloric content of 24 popular snack food products in the U.S. and determined macronutrient content in 10 selected items. Bomb calorimetry and food factors were used to estimate energy content. Macronutrient content was determined according to Official Methods of Analysis. Calorimetric measurements were performed in our metabolic laboratory between April 20th and May 18th and macronutrient content was measured between September 28th and October 7th of 2010. Serving size, by weight, exceeded label statements by 1.2% [median] (25th percentile -1.4, 75th percentile 4.3, P = 0.10). When differences in serving size were accounted for, metabolizable calories were 6.8 kcal (0.5, 23.5, P = 0.0003) or 4.3% (0.2, 13.7, P = 0.001) higher than the label statement. In a small convenience sample of the tested snack foods, carbohydrate content exceeded label statements by 7.7% (0.8, 16.7, P = 0.01); however fat and protein content were not significantly different from label statements (-12.8% [-38.6, 9.6], P = 0.23; 6.1% [-6.1, 17.5], P = 0.32). Carbohydrate content explained 40% and serving size an additional 55% of the excess calories. Among a convenience sample of energy-dense snack foods, caloric content is higher than stated on the nutrition labels, but overall well within FDA limits. This discrepancy may be explained by inaccurate carbohydrate content and serving size. Copyright © 2013 The Obesity Society.

    1982-01-01

    Consistent labeling problems are a family of np-complete constraint satisfaction problems such as school timetabling, for which a conventional computer may be too slow. There are a variety of techniques for reducing the elapsed time to find one or all solutions to a consistent labeling problem. The paper discusses and illustrates solutions consisting of special hardware to accomplish the required constraint propagation and an asynchronous network of intercommunicating computers to accomplish the tree search in parallel. 5 references.

  14. Quantum dot labeling of mesenchymal stem cells

    Directory of Open Access Journals (Sweden)

    Cascio Wayne E

    2007-11-01

    Full Text Available Abstract Background Mesenchymal stem cells (MSCs are multipotent cells with the potential to differentiate into bone, cartilage, fat and muscle cells and are being investigated for their utility in cell-based transplantation therapy. Yet, adequate methods to track transplanted MSCs in vivo are limited, precluding functional studies. Quantum Dots (QDs offer an alternative to organic dyes and fluorescent proteins to label and track cells in vitro and in vivo. These nanoparticles are resistant to chemical and metabolic degradation, demonstrating long term photostability. Here, we investigate the cytotoxic effects of in vitro QD labeling on MSC proliferation and differentiation and use as a cell label in a cardiomyocyte co-culture. Results A dose-response to QDs in rat bone marrow MSCs was assessed in Control (no-QDs, Low concentration (LC, 5 nmol/L and High concentration (HC, 20 nmol/L groups. QD yield and retention, MSC survival, proinflammatory cytokines, proliferation and DNA damage were evaluated in MSCs, 24 -120 hrs post QD labeling. In addition, functional integration of QD labeled MSCs in an in vitro cardiomyocyte co-culture was assessed. A dose-dependent effect was measured with increased yield in HC vs. LC labeled MSCs (93 ± 3% vs. 50% ± 15%, p 90% of QD labeled cells were viable in all groups, however, at 120 hrs increased apoptosis was measured in HC vs. Control MSCs (7.2% ± 2.7% vs. 0.5% ± 0.4%, p Conclusion Fluorescent QDs label MSC effectively in an in vitro co-culture model. QDs are easy to use, show a high yield and survival rate with minimal cytotoxic effects. Dose-dependent effects suggest limiting MSC QD exposure.

    2015-05-14

    This qualitative study employed the Knowledge-Attitude-Behaviour (KAB) model and Health Belief Model (HBM) to investigate factors influencing Thai consumer decision making about use of nutrition labels. Labels include both Nutrition Information Panels (1998-) and Guideline Daily Amounts labels (2011-). In-depth interviews were conducted with 34 participants representing two socio-demographic extremes in Thailand--"urban Bangkok" (university educated consumers) and "provincial Ranong" (non-university educated consumers). An integrated KAB-HBM model was used to devise in-depth interviews for a qualitative study using 20 open-ended questions and samples of food package labels. Additional questions arose from the interviews and they lasted 30-45 minutes and were video recorded. The analysis identified recurring themes using Atlas.ti software. Most participants (n=25) were aware of nutrition labels but a much smaller number (n=10) used and derived any benefit from them. Nutrition label users were classified into 4 groups: A) competent user; B) confused user; C) aware non-user; D) unaware non-user. Better educated participants were better at understanding nutrition labels but not more likely to use labels. Belief that nutrition influences health increased likelihood of using nutrition labels to make decisions about food. Being well-educated and motivated by health concerns increased likelihood of attention to nutrition labels. Results are discussed with a view to increasing the use of nutrition labels by Thai consumers. Our findings, drawing on a combination of the KAB and HBM models, can contribute to strategies motivating consumers to use nutrition labels and can provide useful insights for developing promotional strategies.

  19. Does labeling matter? An examination of attitudes and perceptions of labels for mental disorders.

    Science.gov (United States)

    Szeto, Andrew C H; Luong, Dorothy; Dobson, Keith S

    2013-04-01

    Labeling research in various domains has found that attitudes and perceptions vary as a function of the different labels ascribed to a group (e.g., overweight vs. obese). This type of research, however, has not been examined extensively in regards to labels for mental disorders. The present study examined whether common psychiatric labels (i.e., mental disease, mental disorders, mental health problems, and mental illness) elicited divergent attitudes and perceptions in a group of participants. These labels were also compared to the specific label of depression. Undergraduate psychology students (N = 124) were given identical questionnaire packages with the exception of the label used. That is, each participant received a set of questionnaires that referred to only one of the five labels. The questionnaire package contained various quantitative measures of attitudes and social distance, in addition to a short qualitative measure. Analyses demonstrated equivalence among the four general psychiatric labels on measures of attitudes, social distance, and general perceptions. However, results also suggested that the general labels diverged from the depression label, with the latter being generally more negatively perceived. Some analyses demonstrated that participants' understanding of the terminology might be incorrect. The results of the investigation are discussed with a focus on its relationship with current research in stigma. Within the current sample, general psychiatric labels did not appear to distinguish themselves from each other on measures of attitude and social distance but did so when compared to a relatively more specific term. Future research should examine the underlying mechanism driving this finding, with the ultimate goal of reducing the stigma faced by those with mental disorders.

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents a possible course of action to be taken to provide a means of declaring the sources of electrical power, as is foreseen in the draft of new Swiss electricity market legislation. The report presents the basic ideas behind the idea and defines the terms used such as labelling, certificates and declarations. Also, the legal situation in the European Union and in Switzerland is examined and a quantitative overview of electricity production and consumption is presented. Suggestions for a labelling scheme are made and some of the problems to be expected are looked at. The report also presents a series of examples of labelling schemes already implemented in other countries, such as Austria, Great Britain, Sweden and Germany. Tradable certificates and tracking systems are discussed as are initial quality labels like the Swiss 'Naturemade' label for green power. A concrete recommendation for the declaration and labelling of electricity in Switzerland is presented and various factors to be considered such as import/export, pumped storage, distribution losses, small-scale producers as well as the time-scales for introduction are discussed.

  1. Factors influencing medication label viewing in Malaysia.

    Cheah, Yong Kang; Chong, Yen Wan

    2016-07-12

    The misuse of medicine is a serious public health issue worldwide. An important factor that contributes to the misuse of medicine is the lack of medication label viewing by consumers. The objective of the present study is to examine the socio-economic, demographic and lifestyle factors associated with medication label viewing among Malaysian adults. The empirical analysis is based on a nationally representative data set of 30,992 respondents. An ordered probit model is used to examine different types of medication label viewers. The results of this study suggest that socio-economic (i.e. age, income level, education level, location of residence), demographic (i.e. gender, ethnicity, marital status) and lifestyle factors (i.e. physical activity, smoking) have significant effects on medication label viewing. It is found that age, low-income and low-education level reduce the likelihood of viewing medication label. Based on these findings, several policy implications are suggested. The present study provides policy makers with baseline information regarding which cohorts of individuals to focus on in efforts to increase the frequency of medication label viewing. © The Author(s) 2016.

  2. Gold Nanoparticle Labels Amplify Ellipsometric Signals

    Science.gov (United States)

    Venkatasubbarao, Srivatsa

    2008-01-01

    The ellipsometric method reported in the immediately preceding article was developed in conjunction with a method of using gold nanoparticles as labels on biomolecules that one seeks to detect. The purpose of the labeling is to exploit the optical properties of the gold nanoparticles in order to amplify the measurable ellipsometric effects and thereby to enable ultrasensitive detection of the labeled biomolecules without need to develop more-complex ellipsometric instrumentation. The colorimetric, polarization, light-scattering, and other optical properties of nanoparticles depend on their sizes and shapes. In the present method, these size-and-shape-dependent properties are used to magnify the polarization of scattered light and the diattenuation and retardance of signals derived from ellipsometry. The size-and-shape-dependent optical properties of the nanoparticles make it possible to interrogate the nanoparticles by use of light of various wavelengths, as appropriate, to optimally detect particles of a specific type at high sensitivity. Hence, by incorporating gold nanoparticles bound to biomolecules as primary or secondary labels, the performance of ellipsometry as a means of detecting the biomolecules can be improved. The use of gold nanoparticles as labels in ellipsometry has been found to afford sensitivity that equals or exceeds the sensitivity achieved by use of fluorescence-based methods. Potential applications for ellipsometric detection of gold nanoparticle-labeled biomolecules include monitoring molecules of interest in biological samples, in-vitro diagnostics, process monitoring, general environmental monitoring, and detection of biohazards.

  3. Automated Lobe-Based Airway Labeling

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Regional quantitative analysis of airway morphological abnormalities is of great interest in lung disease investigation. Considering that pulmonary lobes are relatively independent functional unit, we develop and test a novel and efficient computerized scheme in this study to automatically and robustly classify the airways into different categories in terms of pulmonary lobe. Given an airway tree, which could be obtained using any available airway segmentation scheme, the developed approach consists of four basic steps: (1 airway skeletonization or centerline extraction, (2 individual airway branch identification, (3 initial rule-based airway classification/labeling, and (4 self-correction of labeling errors. In order to assess the performance of this approach, we applied it to a dataset consisting of 300 chest CT examinations in a batch manner and asked an image analyst to subjectively examine the labeled results. Our preliminary experiment showed that the labeling accuracy for the right upper lobe, the right middle lobe, the right lower lobe, the left upper lobe, and the left lower lobe is 100%, 99.3%, 99.3%, 100%, and 100%, respectively. Among these, only two cases are incorrectly labeled due to the failures in airway detection. It takes around 2 minutes to label an airway tree using this algorithm.

    As appliance energy efficiency standards and labeling (S&L) programs reach a broader geographic and product scope, a series of sophisticated and complex technical and economic analyses have been adopted by different countries in the world to support and enhance these growing S&L programs. The initial supporting techno-economic and impact analyses for S&L development make up a defined framework and process for setting and developing appropriate appliance efficiency standards and labeling programs. This report reviews in-depth the existing framework for standards setting and label development in the well-established programs of the U.S., Australia and the EU to identify and evaluate major trends in how and why key analyses are undertaken and to understand major similarities and differences between each of the frameworks.

    The Food Allergy Labeling and Consumer Protection Act became effective January 1, 2006, and mandates disclosure of the 8 major allergens in plain English and as a source of ingredients in the ingredient statement. It does not regulate advisory labels. We sought to determine the frequency and language used in voluntary advisory labels among commercially available products and to identify labeling ambiguities affecting consumers with allergy. Trained surveyors performed a supermarket survey of 20,241 unique manufactured food products (from an original assessment of 49,604 products) for use of advisory labels. A second detailed survey of 744 unique products evaluated additional labeling practices. Overall, 17% of 20,241 products surveyed contain advisory labels. Chocolate candy, cookies, and baking mixes were the 3 categories of 24 with the greatest frequency (> or = 40%). Categorically, advisory warnings included "may contain" (38%), "shared equipment" (33%), and "within plant" (29%). The subsurvey disclosed 25 different types of advisory terminology. Nonspecific terms, such as "natural flavors" and "spices," were found on 65% of products and were not linked to a specific ingredient for 83% of them. Additional ambiguities included unclear sources of soy (lecithin vs protein), nondisclosure of sources of gelatin and lecithin, and simultaneous disclosure of "contains" and "may contain" for the same allergen, among others. Numerous products have advisory labeling and ambiguities that present challenges to consumers with food allergy. Additional allergen labeling regulation could improve safety and quality of life for individuals with food allergy.

    One of the aims of the Science and Technology Committee (STC) of the Group on Earth Observations (GEO) was to establish a GEO Label- a label to certify geospatial datasets and their quality. As proposed, the GEO Label will be used as a value indicator for geospatial data and datasets accessible through the Global Earth Observation System of Systems (GEOSS). It is suggested that the development of such a label will significantly improve user recognition of the quality of geospatial datasets and that its use will help promote trust in datasets that carry the established GEO Label. Furthermore, the GEO Label is seen as an incentive to data providers. At the moment GEOSS contains a large amount of data and is constantly growing. Taking this into account, a GEO Label could assist in searching by providing users with visual cues of dataset quality and possibly relevance; a GEO Label could effectively stand as a decision support mechanism for dataset selection. Currently our project - GeoViQua, - together with EGIDA and ID-03 is undertaking research to define and evaluate the concept of a GEO Label. The development and evaluation process will be carried out in three phases. In phase I we have conducted an online survey (GEO Label Questionnaire) to identify the initial user and producer views on a GEO Label or its potential role. In phase II we will conduct a further study presenting some GEO Label examples that will be based on Phase I. We will elicit feedback on these examples under controlled conditions. In phase III we will create physical prototypes which will be used in a human subject study. The most successful prototypes will then be put forward as potential GEO Label options. At the moment we are in phase I, where we developed an online questionnaire to collect the initial GEO Label requirements and to identify the role that a GEO Label should serve from the user and producer standpoint. The GEO Label Questionnaire consists of generic questions to identify whether

    Front-of-pack labeling systems may provide additional guidance to that already available to facilitate the identification of foods that improve diet quality. We examined the association between choosing foods that meet criteria of an established front-of-pack labeling system with food-group and nutrient intakes and cardiometabolic risk factors. The association between the consumption of foods that met 2014 American Heart Association (AHA) Heart-Check Food Certification Program criteria and 2005 Healthy Eating Index (HEI-2005) scores, food-group intake, energy intake, nutrient intake, and cardiometabolic risk factors was analyzed in 11,296 men and women ≥ 19 y old by using 1-d dietary recall data from the NHANES 2007-2010. Individuals were categorized into consumers and nonconsumers of AHA Heart-Check Food Certification Program-certifiable foods and quartiles of intakes on the basis of the percentage of calories. The consumption of AHA Heart-Check Food Certification Program-certifiable foods was positively associated with HEI-2005 scores and fruit, vegetable, whole-grain, total sugar, fiber, potassium, calcium, and vitamin D intakes and inversely associated with the percentage of energy from saturated fat, monounsaturated fat, added sugars, alcohol, and intakes of cholesterol and sodium. The highest quartile of daily energy intake from AHA Heart-Check Food Certification Program-certifiable foods was associated with lower risk of obesity (26%), lower risk of elevated waist circumference (29%), and lower risk of metabolic syndrome (24%) than with lowest intakes (all P front-of-pack labeling system positively influences food-group and nutrient intakes and is associated with a higher diet quality and lower risk of cardiometabolic syndrome.

    There are few objective data on how nutrition labels are used in real-world shopping situations, or how they affect dietary choices and patterns. The Starlight study was a four-week randomised, controlled trial of the effects of three different types of nutrition labels on consumer food purchases: Traffic Light Labels, Health Star Rating labels, or Nutrition Information Panels (control). Smartphone technology allowed participants to scan barcodes of packaged foods and receive randomly allocated labels on their phone screen, and to record their food purchases. The study app therefore provided objectively recorded data on label viewing behaviour and food purchases over a four-week period. A post-hoc analysis of trial data was undertaken to assess frequency of label use, label use by food group, and association between label use and the healthiness of packaged food products purchased. Over the four-week intervention, study participants (n = 1255) viewed nutrition labels for and/or purchased 66,915 barcoded packaged products. Labels were viewed for 23% of all purchased products, with decreasing frequency over time. Shoppers were most likely to view labels for convenience foods, cereals, snack foods, bread and bakery products, and oils. They were least likely to view labels for sugar and honey products, eggs, fish, fruit and vegetables, and meat. Products for which participants viewed the label and subsequently purchased the product during the same shopping episode were significantly healthier than products where labels were viewed but the product was not subsequently purchased: mean difference in nutrient profile score -0.90 (95% CI -1.54 to -0.26). In a secondary analysis of a nutrition labelling intervention trial, there was a significant association between label use and the healthiness of products purchased. Nutrition label use may therefore lead to healthier food purchases. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2015-01-01

    A labelling or numbering of a graph G with q edges is an assignment of labels to the vertices of G that induces for each edge uv a labelling depending on the vertex labels f(u) and f(v). A labelling is called a graceful labelling if there exists an injective function f: V (G) → {0, 1,2,......q} such that for each edge xy, the labelling │f(x)-f(y)│is distinct. In this paper, we prove that a class of Tn trees are even graceful.

    Full Text Available OBJETIVO: Apresentar uma adaptação do Traffic Light Labelling, ou "Semáforo Nutricional", adotado no Reino Unido e outros países da Europa, às normas vigentes no Brasil e classificar produtos industrializados comercializados no país. MÉTODOS: Esta ferramenta baseia-se na utilização das cores do semáforo para valorar concentrações de gorduras total, saturada e trans, açúcar, sódio e fibra correspondente a 100g ou 100mL do produto. O sinal vermelho indica que o nutriente está presente em quantidade excessiva; o amarelo, média e o verde, adequada. Para fibras as baixas concentrações têm cor vermelha e as recomendadas, verde. A adaptação e aplicação desses conceitos para consumidores brasileiros fundamentaram-se nas normas do Regulamento Técnico Referente à Informação Nutricional Complementar da Agência Nacional de Vigilância Sanitária e da Food Standards Agency. RESULTADOS: Foram classificados cem produtos industrializados, os quais foram selecionados da página eletrônica de um hipermercado brasileiro, optando pelos primeiros cinco a oito produtos listados na página, para cada uma das 17 categorias. A análise mostra que são altas as quantidades de gordura total, saturada e sódio e baixas as quantidades de gordura trans e fibra. CONCLUSÃO: A adaptação dessa metodologia visa facilitar a escolha de alimentos saudáveis, sensibilizando os consumidores quanto às desvantagens no que se refere a qualidade nutricional dos alimentos industrializados, e estimular as indústrias a melhorar a composição nutricional de seus produtos, sob a perspectiva de receberem maior quantidade de sinais verdes e menor quantidade de sinais vermelhos; assim, contribuindo para a prevenção de erros alimentares, obesidade e doenças crônicas não-transmissíveis, principais causas de incapacidade e mortes precoces no Brasil.OBJECTIVE: This study presented an adaptation of the Traffic Light Labeling or Nutrition Traffic Light adopted

  3. A Labeling Model Based on the Region of Movability for Point-Feature Label Placement

    Directory of Open Access Journals (Sweden)

    Lin Li

    2016-09-01

    Full Text Available Automatic point-feature label placement (PFLP is a fundamental task for map visualization. As the dominant solutions to the PFLP problem, fixed-position and slider models have been widely studied in previous research. However, the candidate labels generated with these models are set to certain fixed positions or a specified track line for sliding. Thus, the whole surrounding space of a point feature is not sufficiently used for labeling. Hence, this paper proposes a novel label model based on the region of movability, which comes from plane collision detection theory. The model defines a complete conflict-free search space for label placement. On the premise of no conflict with the point, line, and area features, the proposed model utilizes the surrounding zone of the point feature to generate candidate label positions. By combining with heuristic search method, the model achieves high-quality label placement. In addition, the flexibility of the proposed model enables placing arbitrarily shaped labels.

  9. Naming, labeling, and packaging of pharmaceuticals.

    Science.gov (United States)

    Kenagy, J W; Stein, G C

    2001-11-01

    The problem of medical errors associated with the naming, labeling, and packaging of pharmaceuticals is discussed. Sound-alike and look-alike drug names and packages can lead pharmacists and nurses to unintended interchanges of drugs that can result in patient injury or death. The existing medication-use system is flawed because its safety depends on human perfection. Simplicity, standardization, differentiation, lack of duplication, and unambiguous communication are human factors concepts that are relevant to the medication-use process. These principles have often been ignored in drug naming, labeling, and packaging. Instead, current methods are based on long-standing commercial considerations and bureaucratic procedures. The process for naming a marketable drug is lengthy and complex and involves submission of a new chemical entity and patent application, generic naming, brand naming, FDA review, and final approval. Drug companies seek the fastest possible approval and may believe that the incremental benefit of human factors evaluation is small. "Trade dress" is the concept that underlies labeling and packaging issues for the drug industry. Drug companies are resistant to changing trade dress and brand names. Although a variety of private-sector organizations have called for reforms in drug naming, labeling, and packaging standards have been proposed, the problem remains. Drug names, labels, and packages are not selected and designed in accordance with human factors principles. FDA standards do not require application of these principles, the drug industry has struggled with change, and private-sector initiatives have had only limited success.

  10. Restaurant menu labeling laws and alcohol use.

    Restrepo, Brandon J; Ali, Mir M

    2017-09-01

    The goal of this study was to analyze the effect of local and state mandatory restaurant menu labeling laws on alcohol use. Using a difference-in-differences estimation approach and data on adults aged 21 and older (n=2,157,722) from the 2002-2012 Behavioral Risk Factor Surveillance System, we estimated the effect of menu labeling laws on self-reported consumption of alcoholic beverages in the past month. The regression analysis indicates that on average implementation of menu labeling laws is associated with a 1.2 percentage-point drop in the fraction of survey respondents reporting that they drank an alcoholic beverage in the past month (95% confidence interval=-0.020, -0.004), compared with jurisdictions that had not implemented menu labeling laws. Moreover, we find that the estimated policy effects on alcohol use are larger among men than among women and larger among minorities than among non-Hispanic whites. Further provision of calorie information on foods and beverages in food service establishments, such as through federal menu labeling regulations, may have the potential to lead to a meaningful reduction in alcohol use throughout the U.S. and may result in larger reductions in alcohol use among men and minorities.

    2015-11-01

    Problematic prescription drug labeling has been cited as a root cause of patient misunderstanding, medication errors, and nonadherence. Although numerous studies have recently been conducted to identify and test labeling best practices, the last systematic review on this topic was conducted a decade ago. The objective of this review was, therefore, to examine, summarize, and update best practices for conveying written prescription medication information and instructions to patients. English-language articles published from June 2005 to June 2015 were identified in MEDLINE and CINAHL by searching the following text words: 'medication OR prescription OR drug' AND 'label OR leaflet OR brochure OR pamphlet OR medication guide OR medication insert OR drug insert OR medication information OR drug information OR instructions' AND 'patient OR consumer.' Reference mining and secondary searches were also performed. A total of 31 articles providing evidence on how to improve written, prescription drug labeling for patient use were selected. Two reviewers independently screened articles, rated their quality, and abstracted data. Identified best practices included the use of plain language, improved formatting and organization, and more explicit instructions to improve patient comprehension. The use of icons had conflicting findings, and few studies tested whether practices improved knowledge or behaviors with patients' actual prescribed regimens. Future studies are needed to determine how specific modifications and improvements in drug labeling can enhance patient knowledge and behavior in actual use. Synthesizing best practices across all patient materials will create a more useful, coordinated system of prescription information. © The Author(s) 2015.

    OBJECTIVES: Acceleration selective arterial spin labeling (AccASL) is a spatially non-selective labeling technique, used in traditional ASL methods, which labels spins based on their flow acceleration rather than spatial localization. The exact origin of the AccASL signal within the vasculature...... is not completely understood. To obtain more insight into this, the acceleration selective module was performed followed by a velocity selective module, which is used in velocity selective arterial spin labeling (VS-ASL). MATERIALS AND METHODS: Nine healthy volunteers were scanned with various combinations...... of the control and label conditions in both the acceleration and velocity selective module. The cut-off acceleration (0.59 m/s(2)) or velocity (2 cm/s) was kept constant in one module, while it was varied over a large range in the other module. With the right subtractions this resulted in AccASL, VS...

    2009-01-01

    The goal of this research is to investigate the present situation for front of pack labeling in Korea and the perception of consumers for the new system of labeling, front of pack labeling, based on the consumer survey. We investigated the number of processed foods with front of pack labeling in one retailer in Youngin-si. And we also surveyed 1,019 participants nationwide whose ages were from 20 to 49; the knowledge of nutrition labeling, the knowledge of 'front of pack labeling', and the opinion about the labeling system. The data were analyzed using SAS statistics program. The results were as follows: 13.4% of processed foods had front of pack labeling, and 16.8% of the consumers always checked the nutrition labeling, while 32.7% of the consumers seldom checked it. In addition, 44.3% of the consumers think that 'front of pack labeling' is necessary, and 58.3% of the consumers think it is important to show the percentage of daily value as a way of 'front of pack labeling'. However, 32% of the consumer think the possibility of 'front of pack labeling' is slim. Meanwhile, 58.3% of the consumers think that it is important to have the color difference according to contents. The number of favorite nutrients in the front of pack was four or five. It seems that the recognition of current nutrition labeling has the influence on the willingness of using the future 'front of pack labeling'. Along with our study, the policy for 'front of pack labeling' has to be updated and improved constantly since 'front of pack labeling' helps consumer understand nutrition facts.

    2011-01-01

    In 2007, Tacoma-Pierce County Health Department launched a restaurant menu labeling project called SmartMenu. The objective was to recruit locally owned restaurants to voluntarily post basic nutrition information on their menus or menu boards. Participating restaurants submitted recipes to an independent contractor for nutritional analysis and agreed to post calorie, fat, carbohydrate, and sodium values on new menus within 90 days of receiving results. Vigorous recruitment efforts by the Health Department between June 2007 and September 2008 included free advertising, consultation with a Registered Dietitian, and free nutritional analysis. By the end of 2008, a total of 24 restaurants participated in the program. Significant barriers to participation included infrequent use of standardized recipes, perceived business risk of labeling, and low perceived customer demand for nutrition information. Key program elements, recruitment strategies, and costs are discussed. Results have important implications for future efforts to increase the adoption of menu labeling by locally owned and operated restaurants.

    As pharmacists advocate for appropriate use of medications to ensure safety and efficacy for patients, labeling requirements for medications should be considered before patients start new therapies or make changes to their current therapies. In early 2012, the Food and Drug Administration released new mandatory labeling requirements for HMG-CoA reductase inhibitors (more commonly known as "statins") regarding hepatic dysfunction, cognitive impairment, and glycemic control. These requirements are based on a combination of studies, adverse-event reporting databases, and literature reviews. Pharmacists should be prepared to advocate for patient safety and be ready to inform patients and other health care providers of the new labeling requirements and the role pharmacists can play in altering current statin therapy.

    2004-01-01

    BOLD effect imaging is very effective for detection and localization of brain activity, and is the dominant functional imaging technique in cognitive psychology. Despite its efficiency to detect and localize active site, the technique does not lend itself easily to quantifiable measurements. A growingly popular alternative is the use of arterial spin labeling (ASL) to obtain perfusion maps as the indicator of cerebral activation. In this paper, the principles and challenges of arterial spin labeling are discussed and the development of a new fast, two-coil pseudo-continuous labeling scheme is presented. The new scheme permits collection of a multi-slice subtraction pair in less than three seconds, depending on the subject's arterial transit times. The theoretical basis of the technique, as well as a model for quantification of perfusion from the ASL data, are presented. Experimental data from functional imaging experiments were collected to demonstrate the technique and its characteristics.

    2013-12-01

    Full Text Available This work presents an analysis of ecological certification and labelling in the field of tourism. In a tourist company, the certification schemes evaluate the general approach of environmental problems, and impose to the tourist services the observance of pre-established principles and guiding lines concerning the environment. They become for the tourist companies a behavioural standard in the development of their activity. The requirements within such schemes are often flexible and open to interpretation, and generally less controversial than the eco-labelling schemes. As compared to the certification schemes, the eco-labels attributed to the tourist services emphasise the impact over the environment of the services of tourist companies, on the basis of certain European criteria. These criteria refer to the whole life cycle of these tourist services.

  1. Superposition and alignment of labeled point clouds.

    Geometric objects are often represented approximately in terms of a finite set of points in three-dimensional euclidean space. In this paper, we extend this representation to what we call labeled point clouds. A labeled point cloud is a finite set of points, where each point is not only associated with a position in three-dimensional space, but also with a discrete class label that represents a specific property. This type of model is especially suitable for modeling biomolecules such as proteins and protein binding sites, where a label may represent an atom type or a physico-chemical property. Proceeding from this representation, we address the question of how to compare two labeled points clouds in terms of their similarity. Using fuzzy modeling techniques, we develop a suitable similarity measure as well as an efficient evolutionary algorithm to compute it. Moreover, we consider the problem of establishing an alignment of the structures in the sense of a one-to-one correspondence between their basic constituents. From a biological point of view, alignments of this kind are of great interest, since mutually corresponding molecular constituents offer important information about evolution and heredity, and can also serve as a means to explain a degree of similarity. In this paper, we therefore develop a method for computing pairwise or multiple alignments of labeled point clouds. To this end, we proceed from an optimal superposition of the corresponding point clouds and construct an alignment which is as much as possible in agreement with the neighborhood structure established by this superposition. We apply our methods to the structural analysis of protein binding sites.

  2. Labeled Graph Kernel for Behavior Analysis.

    2016-08-01

    Automatic behavior analysis from video is a major topic in many areas of research, including computer vision, multimedia, robotics, biology, cognitive science, social psychology, psychiatry, and linguistics. Two major problems are of interest when analyzing behavior. First, we wish to automatically categorize observed behaviors into a discrete set of classes (i.e., classification). For example, to determine word production from video sequences in sign language. Second, we wish to understand the relevance of each behavioral feature in achieving this classification (i.e., decoding). For instance, to know which behavior variables are used to discriminate between the words apple and onion in American Sign Language (ASL). The present paper proposes to model behavior using a labeled graph, where the nodes define behavioral features and the edges are labels specifying their order (e.g., before, overlaps, start). In this approach, classification reduces to a simple labeled graph matching. Unfortunately, the complexity of labeled graph matching grows exponentially with the number of categories we wish to represent. Here, we derive a graph kernel to quickly and accurately compute this graph similarity. This approach is very general and can be plugged into any kernel-based classifier. Specifically, we derive a Labeled Graph Support Vector Machine (LGSVM) and a Labeled Graph Logistic Regressor (LGLR) that can be readily employed to discriminate between many actions (e.g., sign language concepts). The derived approach can be readily used for decoding too, yielding invaluable information for the understanding of a problem (e.g., to know how to teach a sign language). The derived algorithms allow us to achieve higher accuracy results than those of state-of-the-art algorithms in a fraction of the time. We show experimental results on a variety of problems and datasets, including multimodal data.

  3. Visualizing dengue virus through Alexa Fluor labeling.

    The early events in the interaction between virus and cell can have profound influence on the outcome of infection. Determining the factors that influence this interaction could lead to improved understanding of disease pathogenesis and thus influence vaccine or therapeutic design. Hence, the development of methods to probe this interaction would be useful. Recent advancements in fluorophores development and imaging technology can be exploited to improve our current knowledge on dengue pathogenesis and thus pave the way to reduce the millions of dengue infections occurring annually. The enveloped dengue virus has an external scaffold consisting of 90 envelope glycoprotein (E) dimers protecting the nucleocapsid shell, which contains a single positive strand RNA genome. The identical protein subunits on the virus surface can thus be labeled with an amine reactive dye and visualized through immunofluorescent microscopy. Here, we present a simple method of labeling of dengue virus with Alexa Fluor succinimidyl ester dye dissolved directly in a sodium bicarbonate buffer that yielded highly viable virus after labeling. There is no standardized procedure for the labeling of live virus and existing manufacturer's protocol for protein labeling usually requires the reconstitution of dye in dimethyl sulfoxide. The presence of dimethyl sulfoxide, even in minute quantities, can block productive infection of virus and also induce cell cytotoxicity. The exclusion of the use of dimethyl sulfoxide in this protocol thus reduced this possibility. Alexa Fluor dyes have superior photostability and are less pH-sensitive than the common dyes, such as fluorescein and rhodamine, making them ideal for studies on cellular uptake and endosomal transport of the virus. The conjugation of Alexa Fluor dye did not affect the recognition of labeled dengue virus by virus-specific antibody and its putative receptors in host cells. This method could have useful applications in virological studies.

    A compact and robust magnetic label detector for biomedical assays is implemented in 0.18-μm CMOS. Detection relies on the magnetic relaxation signature of a microbead label for improved tolerance to environmental variations and relaxed dynamic range requirement, eliminating the need for baseline calibration and reference sensors. The device includes embedded electromagnets to eliminate external magnets and reduce power dissipation. Correlated double sampling combined with offset servo loops and magnetic field modulation, suppresses the detector offset to sub-μT. Single 4.5-μm magnetic beads are detected in 16 ms with a probability of error <0.1%. PMID:25308988

  9. Are Luxury Brand Labels and "Green" Labels Costly Signals of Social Status? An Extended Replication.

    Directory of Open Access Journals (Sweden)

    Joël Berger

    Full Text Available Costly signaling theory provides an explanation for why humans are willing to a pay a premium for conspicuous products such as luxury brand-labeled clothing or conspicuous environmentally friendly cars. According to the theory, the extra cost of such products is a signal of social status and wealth and leads to advantages in social interactions for the signaler. A previous study found positive evidence for the case of luxury brand labels. However, an issue of this study was that some of the experiments were not conducted in a perfectly double-blind manner. I resolved this by replicating variations of the original design in a double-blind procedure. Additionally, besides the luxury label condition, I introduced a "green" label condition. Thus, the hypothesis that signaling theory is able to explain pro-environmental behavior was tested for the first time in a natural field setting. Further, I conducted experiments in both average and below-average socioeconomic neighborhoods, where, according to signaling theory, the effects of luxury signals should be even stronger. In contrast to the original study, I did not find positive effects of the luxury brand label in any of the five experiments. Nor did I find evidence for a green-signaling effect. Moreover, in poor neighborhoods a negative tendency of the luxury label actually became evident. This suggests that a signaling theory explanation of costly labels must take into account the characteristics of the observers, e.g. their social status.

    In recent years, optical label switching (OLS) gains lots of attentions due to its intrinsic advantages to implement protocol, bit-rate, granularity and data format transparency packet switching. In this paper, we propose a novel scheme to realize flexible-rate optical packet switching for OLS networks. At the transmitter node, flexible-rate packet is generated by parallel modulating different combinations of optical carriers generated from the optical multi-carrier generator (OMCG), among which the low-speed optical label occupies one carrier. At the switching node, label is extracted and re-generated in label processing unit (LPU). The payloads are switched based on routing information and new label is added after switching. At the receiver node, another OMCG serves as local oscillators (LOs) for optical payloads coherent detection. The proposed scheme offers good flexibility for dynamic optical packet switching by adjusting the payload bandwidth and could also effectively reduce the number of lasers, modulators and receivers for packet generation/detection. We present proof-of-concept demonstrations of flexible-rate packet generation/detection and label swapping in 12.5 GHz grid. The influence of crosstalk for cascaded label swapping is also investigated.

  12. Insight into the labeling mechanism of acceleration selective arterial spin labeling.

    2017-04-01

    Acceleration selective arterial spin labeling (AccASL) is a spatially non-selective labeling technique, used in traditional ASL methods, which labels spins based on their flow acceleration rather than spatial localization. The exact origin of the AccASL signal within the vasculature is not completely understood. To obtain more insight into this, the acceleration selective module was performed followed by a velocity selective module, which is used in velocity selective arterial spin labeling (VS-ASL). Nine healthy volunteers were scanned with various combinations of the control and label conditions in both the acceleration and velocity selective module. The cut-off acceleration (0.59 m/s2) or velocity (2 cm/s) was kept constant in one module, while it was varied over a large range in the other module. With the right subtractions this resulted in AccASL, VS-ASL, combined AccASL and VS-ASL signal, and signal from one module with crushing from the other. The label created with AccASL has an overlap of approximately 50% in the vascular region with VS-ASL, but also originates from smaller vessels closer to the capillaries. AccASL is able to label spins both in the macro- and meso-vasculature, as well as in the microvasculature.

  13. Structured Labels in Random Forests for Semantic Labelling and Object Detection.

    2014-10-01

    Ensembles of randomized decision trees, known as Random Forests, have become a valuable machine learning tool for addressing many computer vision problems. Despite their popularity, few works have tried to exploit contextual and structural information in random forests in order to improve their performance. In this paper, we propose a simple and effective way to integrate contextual information in random forests, which is typically reflected in the structured output space of complex problems like semantic image labelling. Our paper has several contributions: We show how random forests can be augmented with structured label information and be used to deliver structured low-level predictions. The learning task is carried out by employing a novel split function evaluation criterion that exploits the joint distribution observed in the structured label space. This allows the forest to learn typical label transitions between object classes and avoid locally implausible label configurations. We provide two approaches for integrating the structured output predictions obtained at a local level from the forest into a concise, global, semantic labelling. We integrate our new ideas also in the Hough-forest framework with the view of exploiting contextual information at the classification level to improve the performance on the task of object detection. Finally, we provide experimental evidence for the effectiveness of our approach on different tasks: Semantic image labelling on the challenging MSRCv2 and CamVid databases, reconstruction of occluded handwritten Chinese characters on the Kaist database and pedestrian detection on the TU Darmstadt databases.

  14. A consumer perspective on food labelling: ethical or not?

    2010-07-01

    Full Text Available This article provides a review of ethical food labelling from a consumer perspective and makes recommendations to the food industry and regulators regarding ethical food labelling in order to satisfy consumers’ food-labelling needs. Various studies have found that many consumers have negative perceptions regarding food labelling. However, research on consumers’ perspectives regarding ethical food labelling has been accorded little attention. This article addresses this topic through a review of the relevant literature of mostly quantitative research, but also includes qualitative and mixed method studies. The article examines such aspects as the trustworthiness of claims on food labels, intelligibility of label information, listing of food additives on labels, and labelling of genetically modified foods. As negative perspectives on food labelling are likely to affect consumers’ decision making regarding the purchasing of food products, the food industry must realise their responsibility to provide ethical food labels. The food industry and regulators should aim to provide risk communication and intelligible information through ethical food labels and consumer education programmes on food labelling. Consumers need to be aware of their right to know what they are purchasing through ethical food labels and take a stand in this regard.

  2. Label-Free Sensing on Microarrays.

    Science.gov (United States)

    Sun, Yung-Shin

    2017-01-01

    Microarrays of biological molecules such as DNAs, proteins, carbohydrates, and small molecules provide a high-throughput platform for screening tens of thousands of biomolecular interactions simultaneously, facilitating the functional characterization of these biomolecules in areas of genomics, proteomics, glycomics, and cytomics. Routinely, analysis of binding reactions between solution-phased probes and surface-immobilized targets involves some kinds of fluorescence-based detection methods. Even though these methods have advantages of high sensitivity and wide dynamic range, labeling probes and/or targets inevitably changes their innate properties and in turn affects probe-target interactions in often uncharacterized ways. Therefore, in recent years, various label-free sensing technologies have been developed for characterizing biomolecular interactions in microarray format. These biosensors, to a certain extent, take the place of fluorescent methods by providing a comparable sensitivity as well as retaining the conformational and functional integrality of biomolecules to be investigated. More importantly, some of these biosensors are capable of real-time monitoring probe-target interactions, providing the binding affinities of these reactions. Using label-free biosensors in microarrays has become a current trend in developing high-throughput screening platforms for drug discoveries and applications in all areas of "-omics." This article is aimed to provide principles and recent developments in label-free sensing technologies applicable to microarrays, with special attentions being paid to surface plasmon resonance microscopy and oblique-incidence reflectivity difference microscopy.

  3. Microfluidic Radiometal Labeling Systems for Biomolecules

    Energy Technology Data Exchange (ETDEWEB)

    Reichert, D E; Kenis, P J. A.

    2011-12-29

    In a typical labeling procedure with radiometals, such as Cu-64 and Ga-68; a very large (~ 100-fold) excess of the non-radioactive reactant (precursor) is used to promote rapid and efficient incorporation of the radioisotope into the PET imaging agent. In order to achieve high specific activities, careful control of reaction conditions and extensive chromatographic purifications are required in order to separate the labeled compounds from the cold precursors. Here we propose a microfluidic approach to overcome these problems, and achieve high specific activities in a more convenient, semi-automated fashion and faster time frame. Microfluidic reactors, consisting of a network of micron-sized channels (typical dimensions in the range 10 - 300¼m), filters, separation columns, electrodes and reaction loops/chambers etched onto a solid substrate, are now emerging as an extremely useful technology for the intensification and miniaturization of chemical processes. The ability to manipulate, process and analyze reagent concentrations and reaction interfaces in both space and time within the channel network of a microreactor provides the fine level of reaction control that is desirable in PET radiochemistry practice. These factors can bring radiometal labeling, specifically the preparation of radio-labeled biomolecules such as antibodies, much closer to their theoretical maximum specific activities.

  18. Generating Realistic Labelled, Weighted Random Graphs

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs. Our results allow us to draw conclusions about the contribution of vertex labels and edge weights to graph structure.

  19. Preparation of Labeled Aflatoxins with High Specific Activities

    1971-01-01

    Resting cells of Aspergillus parasiticus ATCC 15517 were used to prepare highly labeled aflatoxins from labeled acetate. High synthetic activity in growing cells was evidenced only during 40 to 70 hr of incubation. Glucose was required for high incorporation efficiency, whereas the concentration of the labeled acetate determined the specific activity of the product. When labeled acetate was continuously added to maintain a concentration near but not exceeding 10 mm, in a culture containing 30 g of glucose per liter, 2% of its labels could be recovered in the purified aflatoxins which have a specific activity more than three times that of the labeled acetate.

  1. China Refrigerator Information Label: Specification Development and Potential Impact

    2008-02-01

    requirements to achieve grade 1 on the label are now virtually as stringent as those for US Energy Star-qualified or EU A-grade refrigerators. When the energy information label went into effect in March 2005, refrigerator manufacturers were required to display their declared level of efficiency on the label and report it to the China Energy Label Center (CELC), a newly established unit of CNIS responsible for label program management. Because of the visible nature of the label, it was found, through a METI/IEEJ-supported study, that MEPS non-compliance dropped from 4% to zero after the label became mandatory, and that the percentage of higher-grade refrigerators increased. This suggests that the label itself does have potential for shifting the market to higher-efficiency models (Lin 2007). One challenge, however, of assessing this potential impact is the lack of a comprehensive baseline of market efficiency and a program to evaluate the market impact on a yearly basis. As a result, the impact evaluation in this study draws upon the market transformation experience of the related EU energy information label, for which quantitative assessments of its market impact exist. By assuming a parallel process unfolding in China, it is possible to look at the potential impact of the label to 2020. The results of the analysis demonstrates that a robust market transformation program in China focused on the energy information label could save substantial amounts of electricity by 2020, totaling 16.4 TWh annually by that year, compared to a case in which the efficiency distribution of refrigerators was frozen at the 2007 level. Remarkably, the impact of a successful market transformation program with the label would essentially flatten the consumption of electricity for refrigerator use throughout most of the next decade, despite the expectations of continued growth in total stock by nearly 190 million units. At the end of this period, total consumption begins to rise again, as the least

    Raloxifene, [6-hydroxy-2-(4-hydroxy-phenyl) benzo [b] thiophen-3-yl]-[4-(2-piperidin-1-yl-ethoxy)phenyl] methanone, a tissue-selective estrogen mixed agonist/antagonist, classified as a selective estrogen receptor modulator (SERM), is currently under clinical evaluation for the prevention and treatment of postmenopausal osteoporosis, breast cancer, uterine dysfunction, and other disorders of the female reproductive system. Based on SAR studies of substituted raloxifenes, we synthesized 3 kinds of fluoroalkylated raloxifene derivatives. These compounds show high relative binding affinities (RBA) to the estrogen receptor in vitro (RBA of estradiol = 100%). The RBA values for compounds 1, 2 and 3 are 89, 60, and 45%, respectively, which are all higher than that of raloxifene itself (34%). Among these compounds, we selected to take the best RBA value one and F-18 labeled. Using 2 kinds of labeling method ; 1) Radiolabeling using [{sup 18}F]KF was carried out in anhydrous acetonitrile for 10 min at 120 .deg. C. 2) Radiolabeling using [{sup 18}F]KF was carried out in anhydrous acetonitrile for 15 min at 120 .deg. C in ionic liquid, [bmim][OTf]. Deprotection step added 1N HCl and reacted for 3 min at 120 .deg. C. [{sup 18}F]Fluoroethyl raloxifene derivative obtained 5-23% decay corrected labeling yield by HPLC system (C18 xterra, 10 i, 34% Acetonitrile/0.1 M formate buffer, flow rate: 4 mL/1 min, collection time : 28-29 min) and total time was around 70 min. Fluoroethyl raloxifene derivative has the best RBA value among the other synthesized derivatives and chose it for radiolabeling. [{sup 18}F]Fluoroethyl raloxifene derivative prepared 5-23% decay corrected labeling yield. This preparation is on going for labeling optimizing and preparing of in vitro and in vivo test.

  5. Label propagation algorithm for community detection based on node importance and label influence

    2017-09-01

    Recently, the detection of high-quality community has become a hot spot in the research of social network. Label propagation algorithm (LPA) has been widely concerned since it has the advantages of linear time complexity and is unnecessary to define objective function and the number of community in advance. However, LPA has the shortcomings of uncertainty and randomness in the label propagation process, which affects the accuracy and stability of the community. For large-scale social network, this paper proposes a novel label propagation algorithm for community detection based on node importance and label influence (LPA_NI). The experiments with comparative algorithms on real-world networks and synthetic networks have shown that LPA_NI can significantly improve the quality of community detection and shorten the iteration period. Also, it has better accuracy and stability in the case of similar complexity.

    Full Text Available Inspired by the method of Koh et al. (1979 of combining known graceful trees to construct bigger graceful trees, a new class of graceful trees is constructed from a set of k known graceful trees, k≥2 in a specific way. In fact, each member of this new class of trees admits α-labeling, a stronger version of graceful labeling. Consequently, each member of this family of trees decomposes complete graphs and complete bipartite graphs.

  8. Facial Action Unit Recognition under Incomplete Data Based on Multi-label Learning with Missing Labels

    KAUST Repository

    Li, Yongqiang

    2016-07-07

    Facial action unit (AU) recognition has been applied in a wild range of fields, and has attracted great attention in the past two decades. Most existing works on AU recognition assumed that the complete label assignment for each training image is available, which is often not the case in practice. Labeling AU is expensive and time consuming process. Moreover, due to the AU ambiguity and subjective difference, some AUs are difficult to label reliably and confidently. Many AU recognition works try to train the classifier for each AU independently, which is of high computation cost and ignores the dependency among different AUs. In this work, we formulate AU recognition under incomplete data as a multi-label learning with missing labels (MLML) problem. Most existing MLML methods usually employ the same features for all classes. However, we find this setting is unreasonable in AU recognition, as the occurrence of different AUs produce changes of skin surface displacement or face appearance in different face regions. If using the shared features for all AUs, much noise will be involved due to the occurrence of other AUs. Consequently, the changes of the specific AUs cannot be clearly highlighted, leading to the performance degradation. Instead, we propose to extract the most discriminative features for each AU individually, which are learned by the supervised learning method. The learned features are further embedded into the instance-level label smoothness term of our model, which also includes the label consistency and the class-level label smoothness. Both a global solution using st-cut and an approximated solution using conjugate gradient (CG) descent are provided. Experiments on both posed and spontaneous facial expression databases demonstrate the superiority of the proposed method in comparison with several state-of-the-art works.

    2016-05-01

    Mandatory and voluntary menu-labeling policies are increasingly common to support informed food choices among consumers. This study sought to examine stakeholder perspectives of developing, implementing, and maintaining a voluntary menu-labeling program in a hospital cafeteria setting. Semi-structured qualitative interviews were conducted with 9 key cafeteria stakeholders. Data were coded by 2 independent researchers. Themes were generated deductively around 4 key themes: (1) motivation for the program; (2) program and menu development; (3) program implementation process; and, (4) "lessons learned," and inductively as they emerged from interview transcripts. These themes were mapped onto Damschroder's Consolidated Framework for Implementation Research. Motivations for the program were both internal and external to enable consumers to make educated food choices. Barriers to implementation included financial resources, digital menu board maintenance, and availability of healthy options from providers. Supports included availability of nutritional analysis software and nutritional information, and controlled food preparation. Ownership, program adaptation, a supportive collegial environment, a program champion and a culture valuing healthy eating were conducive to successful implementation. Both internal and external factors can support the voluntary implementation of menu-labeling programs.

    2013-12-01

    In the United States (US), based on the 2010 Affordable Care Act, restaurant chains and similar retail food establishments with 20 or more locations are required to begin implementing calorie information on their menus. As enacting of the law begins, it is important to understand its potential for improving consumers' healthful behaviors. Therefore, the objective of this study was to explore relationships among users of grocery nutrition labels and attitudes toward restaurant menu labeling, along with the caloric content of their restaurant menu selection. Study participants were surveyed and then provided identical mock restaurant menus with or without calories. Results found that participants who used grocery nutrition labels and believed they would make healthy menu selections with nutrition labels on restaurant menus made healthier menu selections, regardless of whether the menu displayed calories or not. Consumers' nutrition knowledge and behaviors gained from using grocery nutrition labels and consumers' desire for restaurants to provide nutrition menu labels have a positive effect on their choosing healthful restaurant menu items.

This cross-sectional study surveyed adults, 60 years and older in Delaware (n = 100, 82% female, 74% between 60 and 79 years, 49% Caucasian, 45% African Americans) to examine associations between food label knowledge, attitudes, and usage patterns. A 28-item questionnaire assessed knowledge, attitudes, usage, and demographic information. Bivariate analysis results showed food label knowledge was associated with education and monthly income. Those reporting a high school education or less incorrectly identified calorie (P Label usage was associated with being female (P label comprehension was high; however less than half could correctly interpret label information. When shown samples of the US Food and Drug Administration's proposed new labels, subjects had a very favorable attitude toward the new changes. Increasing nutrition knowledge through education interventions appropriate for older adult consumers may improve comprehension of information on the food labels.

    Front-of-package (FOP) labels are increasing in popularity on retail products. Reductive FOP labels provide nutrient-specific information, whereas evaluative FOP labels summarize nutrient information through icons. Better understanding of consumer behavior regarding FOP labels is beneficial to increasing consumer use of nutrition labeling when making grocery purchasing decisions. We aimed to determine FOP label format effectiveness in aiding consumers at assessing nutrient density of food products. In addition, we sought to determine relationships between FOP label use and attitude toward healthy eating, diet self-assessment, self-reported health and nutrition knowledge, and label and shopping behaviors. A between-subjects experimental design was employed. Participants were randomly assigned to one of four label conditions: Facts Up Front, Facts Up Front Extended, a binary symbol, and no-label control. One hundred sixty-one US primary grocery shoppers, aged 18 to 69 years. Participants were randomly invited to the online study. Participants in one of four label condition groups viewed three product categories (cereal, dairy, and snacks) with corresponding questions. Adults' nutrition assessment of food products based on different FOP label formats, along with label use and attitude toward healthy eating, diet self-assessment, self-reported health and nutrition knowledge, and label and shopping behaviors. Data analyses included descriptive statistics, χ2 tests, and logistical regression. Significant outcomes were set to α=.05. Participants selected the more nutrient-dense product in the snack food category when it contained an FOP label. Subjective health and nutrition knowledge and frequency of selecting food for healthful reasons were associated with FOP label use (Pattitude and behavior factors were associated with label use.

    Direct bromination of the tyrosine residues of peptides and antibodies with bromine-76, to create probes for PET imaging, has been reported. For peptides that do not contain tyrosine residues, however, a prosthetic group is required to achieve labeling via conjugation to other functional groups such as terminal α-amines or lysine ε-amines. The goal of this study was to develop new strategies for labeling small peptides with Br-76 using either a direct labeling method or a prosthetic group, depending on the available functional group on the peptides. A new labeling agent, N-succinimidyl-3-[(76)Br]bromo-2,6-dimethoxybenzoate ([(76)Br]SBDMB) was prepared for cyclic RGD peptide labeling. N-succinimidyl-2, 6-dimethoxybenzoate was also used to pre-attach a 2, 6-dimethoxybenzoyl (DMB) moiety to the peptide, which could then be labeled with Br-76. A competitive cell binding assay was performed to determine the binding affinity of the brominated peptides. PET imaging of U87MG human glioblastoma xenografted mice was performed using [(76)Br]-BrE[c(RGDyK)](2) and [(76)Br]-BrDMB-E[c(RGDyK)](2). An ex vivo biodistribution assay was performed to confirm PET quantification. The mechanisms of bromination reaction between DMB-c(RGDyK) and the brominating agent CH(3)COOBr were investigated with the SCRF-B3LYP/6-31G* method with the Gaussian 09 program package. The yield for direct labeling of c(RGDyK) and E[c(RGDyK)](2) using chloramine-T and peracetic acid at ambient temperature was greater than 50%. The yield for [(76)Br]SBDMB was over 60% using peracetic acid. The conjugation yields for labeling c(RGDfK) and c(RGDyK) were over 70% using the prosthetic group at room temperature. Labeling yield for pre-conjugated peptides was over 60%. SDMB conjugation and bromination did not affect the binding affinity of the peptides with integrin receptors. Both [(76)Br]Br-E[c(RGDyK)](2) and [(76)Br]BrDMB-E[c(RGDyK)](2) showed high tumor uptake in U87MG tumor bearing mice. The specificity of

    Respiratory enteric orphan virus (reovirus) has been used to study many aspects of the biology and genetics of viruses, viral infection, pathogenesis, and the immune response to virus infection. This report describes the functional activity of virus labeled with Alexa Fluor 488, a stable fluorescent dye. Matrix assisted laser desorption-time of flight analysis indicated that Alexa Fluor 488 labeled the outer capsid proteins of reovirus. Labeled virus bound to murine L929 fibroblasts as determined by flow cytometry and fluorescence microscopy, and the specificity of binding were demonstrated by competitive inhibition with non-labeled virus. Labeled reovirus induced apoptosis and cytopathic effect in infected L929 cells. Mice infected with labeled virus mounted robust serum antibody and CD8(+) T-cell responses, indicating that labeled virus retained immunogenicity in vivo. These results indicate that Alexa Fluor 488-labeled virus provides a powerful new tool to analyze reovirus infection in vitro and in vivo.

    Graceful labeling is one of the interesting topics in graph theory. Let G(V, E) is a graph. The injective mapping f: V → {0, 1, …, |E|} is called graceful if the weight of edge w(uv) = |f(u) - f(v)| are all different for every edge uv. The famous conjecture in graceful labeling is "all trees are graceful". Previous research had proved that caterpillar graph is graceful. There also a research that has introduced the supercaterpillar graph and already proved supercaterpillar satisfying certain conditions are also graceful. In this paper, we generalized the concept of supercaterpillar and show subclass of supercaterpillar graph that has not been discussed earlier is also graceful.

  7. Supervised Sequence Labelling with Recurrent Neural Networks

    CERN Document Server

    Graves, Alex

    2012-01-01

    Supervised sequence labelling is a vital area of machine learning, encompassing tasks such as speech, handwriting and gesture recognition, protein secondary structure prediction and part-of-speech tagging. Recurrent neural networks are powerful sequence learning tools—robust to input noise and distortion, able to exploit long-range contextual information—that would seem ideally suited to such problems. However their role in large-scale sequence labelling systems has so far been auxiliary.    The goal of this book is a complete framework for classifying and transcribing sequential data with recurrent neural networks only. Three main innovations are introduced in order to realise this goal. Firstly, the connectionist temporal classification output layer allows the framework to be trained with unsegmented target sequences, such as phoneme-level speech transcriptions; this is in contrast to previous connectionist approaches, which were dependent on error-prone prior segmentation. Secondly, multidimensional...

    The ability to measure the kinetics of vesicle release can help provide insight into some of the basics of neurotransmission. Here we used real-time imaging of vesicles labeled with FM dye to monitor the rate of presynaptic vesicle release. FM4-64 is a red fluorescent amphiphilic styryl dye that embeds into the membranes of synaptic vesicles as endocytosis is stimulated. Lipophilic interactions cause the dye to greatly increase in fluorescence, thus emitting a bright signal when associated...

    Cincinnati Children's Hospital Medical Center (CCHMC) has built the initial Natural Language Processing (NLP) component to extract medications with their corresponding medical conditions (Indications, Contraindications, Overdosage, and Adverse Reactions) as triples of medication-related information ([(1) drug name]-[(2) medical condition]-[(3) LOINC section header]) for an intelligent database system, in order to improve patient safety and the quality of health care. The Food and Drug Administration's (FDA) drug labels are used to demonstrate the feasibility of building the triples as an intelligent database system task. This paper discusses a hybrid NLP system, called AutoMCExtractor, to collect medical conditions (including disease/disorder and sign/symptom) from drug labels published by the FDA. Altogether, 6,611 medical conditions in a manually-annotated gold standard were used for the system evaluation. The pre-processing step extracted the plain text from XML file and detected eight related LOINC sections (e.g. Adverse Reactions, Warnings and Precautions) for medical condition extraction. Conditional Random Fields (CRF) classifiers, trained on token, linguistic, and semantic features, were then used for medical condition extraction. Lastly, dictionary-based post-processing corrected boundary-detection errors of the CRF step. We evaluated the AutoMCExtractor on manually-annotated FDA drug labels and report the results on both token and span levels. Precision, recall, and F-measure were 0.90, 0.81, and 0.85, respectively, for the span level exact match; for the token-level evaluation, precision, recall, and F-measure were 0.92, 0.73, and 0.82, respectively. The results demonstrate that (1) medical conditions can be extracted from FDA drug labels with high performance; and (2) it is feasible to develop a framework for an intelligent database system.

  12. Robust Statistical Label Fusion through Consensus Level, Labeler Accuracy and Truth Estimation (COLLATE)

    2011-01-01

    Segmentation and delineation of structures of interest in medical images is paramount to quantifying and characterizing structural, morphological, and functional correlations with clinically relevant conditions. The established gold standard for performing segmentation has been manual voxel-by-voxel labeling by a neuroanatomist expert. This process can be extremely time consuming, resource intensive and fraught with high inter-observer variability. Hence, studies involving characterizations of novel structures or appearances have been limited in scope (numbers of subjects), scale (extent of regions assessed), and statistical power. Statistical methods to fuse data sets from several different sources (e.g., multiple human observers) have been proposed to simultaneously estimate both rater performance and the ground truth labels. However, with empirical datasets, statistical fusion has been observed to result in visually inconsistent findings. So, despite the ease and elegance of a statistical approach, single observers and/or direct voting are often used in practice. Hence, rater performance is not systematically quantified and exploited during label estimation. To date, statistical fusion methods have relied on characterizations of rater performance that do not intrinsically include spatially varying models of rater performance. Herein, we present a novel, robust statistical label fusion algorithm to estimate and account for spatially varying performance. This algorithm, COnsensus Level, Labeler Accuracy and Truth Estimation (COLLATE), is based on the simple idea that some regions of an image are difficult to label (e.g., confusion regions: boundaries or low contrast areas) while other regions are intrinsically obvious (e.g., consensus regions: centers of large regions or high contrast edges). Unlike its predecessors, COLLATE estimates the consensus level of each voxel and estimates differing models of observer behavior in each region. We show that COLLATE provides

    Full Text Available The objective of this study was to verify whether the labels of UHT milk carton marketed in supermarkets of Curitiba-PR were in accordance with the standards established by the Brazilian Ministry of Agriculture, Livestock and Food Supply (MAPA. The samples collected were from industries that followed the federal inspection regime and the brands were marketed in the main supermarket chains. We evaluated 18 labels of UHT milk regarding the labeling standards present in the legislation declared by MAPA. It was performed visits to the supermarkets and the application of a check list containing 27 items (classified as “in accordance with”, “not in accordance with” and “not applicable” in each package. Among the brands evaluated, 15 (83% revealed some nonconformity that includes the highlight to the presence or absence of components intrinsic to the product and/or the highlight to the presence of components added to all products of similar manufacture. This fact can lead to mistakes in the purchase and generate false expectations to the consumers.

    2010-11-01

    The huge amount of video data generated by surveillance systems necessitates the use of automatic tools for their efficient analysis, indexing, and retrieval. Automated access to the semantic content of surveillance videos to detect anomalous events is among the basic tasks; however, due to the high variability of the audio-visual features and large size of the video input, it still remains a challenging task, though a considerable amount of research dealing with automated access to video surveillance has appeared in the literature. We propose a keyframe labeling technique, especially for indoor environments, which assigns labels to keyframes extracted by a keyframe detection algorithm, and hence transforms the input video to an event-sequence representation. This representation is used to detect unusual behaviors, such as crossover, deposit, and pickup, with the help of three separate mechanisms based on finite state automata. The keyframes are detected based on a grid-based motion representation of the moving regions, called the motion appearance mask. It has been shown through performance experiments that the keyframe labeling algorithm significantly reduces the storage requirements and yields reasonable event detection and classification performance.

  16. Homogeneous Biosensing Based on Magnetic Particle Labels

    2016-06-06

    The growing availability of biomarker panels for molecular diagnostics is leading to an increasing need for fast and sensitive biosensing technologies that are applicable to point-of-care testing. In that regard, homogeneous measurement principles are especially relevant as they usually do not require extensive sample preparation procedures, thus reducing the total analysis time and maximizing ease-of-use. In this review, we focus on homogeneous biosensors for the in vitro detection of biomarkers. Within this broad range of biosensors, we concentrate on methods that apply magnetic particle labels. The advantage of such methods lies in the added possibility to manipulate the particle labels by applied magnetic fields, which can be exploited, for example, to decrease incubation times or to enhance the signal-to-noise-ratio of the measurement signal by applying frequency-selective detection. In our review, we discriminate the corresponding methods based on the nature of the acquired measurement signal, which can either be based on magnetic or optical detection. The underlying measurement principles of the different techniques are discussed, and biosensing examples for all techniques are reported, thereby demonstrating the broad applicability of homogeneous in vitro biosensing based on magnetic particle label actuation.

  17. Penicillin allergy-getting the label right.

    Science.gov (United States)

    2017-03-01

    Penicillini allergy is a potentially serious adverse reaction that impacts on antibacterial treatment options. Although it is commonly reported and recorded in medical records, only a minority of patients with a label of penicillin allergy actually have the condition confirmed. The term 'allergy' may be incorrectly applied to adverse reactions that do not have an immunological basis and inappropriate labelling of penicillin allergy can lead to the unnecessary avoidance of penicillins and other beta-lactam antibacterials. Here, we discuss key features that help to distinguish patients at low or high risk of having a true penicillin allergy, summarise what is known about the risk of allergic reactions to other beta-lactam antibacterials in patients with penicillin allergy and discuss the steps to consider when assessing a label of penicillin allergy.

    2013-02-01

    Photoacoustic microscopy (PAM) has achieved submicron lateral resolution in showing subcellular structures; however, relatively few endogenous subcellular contrasts have so far been imaged. Given that the hemeprotein, mostly cytochromes in general cells, is optically absorbing around the Soret peak (˜420 nm), we implemented label-free PAM of cytochromes in cytoplasm for the first time. By measuring the photoacoustic spectra of the oxidized and reduced states of fibroblast lysate and fitting the difference spectrum with three types of cytochromes, we found that the three cytochromes account for more than half the optical absorption in the cell lysate at 420 nm wavelength. Fixed fibroblasts on slides were imaged by PAM at 422 and 250 nm wavelengths to reveal cytoplasms and nuclei, respectively, as confirmed by standard staining histology. PAM was also applied to label-free histology of mouse ear sections by showing cytoplasms and nuclei of various cells. PAM of cytochromes in cytoplasm is expected to be a high-throughput, label-free technique for studying live cell functions, which cannot be accomplished by conventional histology.

  19. Semantic Labeling of Nonspeech Audio Clips

    2010-01-01

    Full Text Available Human communication about entities and events is primarily linguistic in nature. While visual representations of information are shown to be highly effective as well, relatively little is known about the communicative power of auditory nonlinguistic representations. We created a collection of short nonlinguistic auditory clips encoding familiar human activities, objects, animals, natural phenomena, machinery, and social scenes. We presented these sounds to a broad spectrum of anonymous human workers using Amazon Mechanical Turk and collected verbal sound labels. We analyzed the human labels in terms of their lexical and semantic properties to ascertain that the audio clips do evoke the information suggested by their pre-defined captions. We then measured the agreement with the semantically compatible labels for each sound clip. Finally, we examined which kinds of entities and events, when captured by nonlinguistic acoustic clips, appear to be well-suited to elicit information for communication, and which ones are less discriminable. Our work is set against the broader goal of creating resources that facilitate communication for people with some types of language loss. Furthermore, our data should prove useful for future research in machine analysis/synthesis of audio, such as computational auditory scene analysis, and annotating/querying large collections of sound effects.

    2016-07-19

    Protein structural and functional studies rely on complete qualitative and quantitative information on protein species (proteoforms); thus, it is important to quantify differentially expressed proteins at their molecular level. Here we report our development of universal pseudoisobaric dimethyl labeling (pIDL) of amino groups at both the N-terminal and lysine residues for relative quantitation of intact proteins. Initial proof-of-principle study was conducted on standard protein myoglobin and hepatocellular proteomes (HepG2 vs LO2). The amino groups from both the N-terminal and lysine were dimethylated with HXHO (X = (13)C or C) and NaBY3CN (Y = H or D). At the standard protein level, labeling efficiency, effect of product ion size, and mass resolution on quantitation accuracy were explored; and a good linear quantitation dynamic range up to 50-fold was obtained. For the hepatocellular proteome samples, 33 proteins were quantified with RSD ≤ 10% from one-dimensional reversed phase liquid chromatography-tandem mass spectrometry (RPLC-MS/MS) analysis of the 1:1 mixed samples. The method in this study can be extended to quantitation of other intact proteome systems. The universal "one-pot" dimethyl labeling of all the amino groups in a protein without the need of preblocking of those on the lysine residues is made possible by protein identification and quantitation analysis using ProteinGoggle 2.0 with customized databases of both precursor and product ions containing heavy isotopes.

    Highlights: • Membrane protein Orai1 can be used to report the fusion properties of RFPs. • Artificial puncta are affected by dissociation constant as well as pKa of RFPs. • Among tested RFPs mOrange2 is the best choice for secretory protein labeling. - Abstract: Red fluorescent proteins (RFPs) are useful tools for live cell and multi-color imaging in biological studies. However, when labeling proteins in secretory pathway, many RFPs are prone to form artificial puncta, which may severely impede their further uses. Here we report a fast and easy method to evaluate RFPs fusion properties by attaching RFPs to an environment sensitive membrane protein Orai1. In addition, we revealed that intracellular artificial puncta are actually colocalized with lysosome, thus besides monomeric properties, pKa value of RFPs is also a key factor for forming intracellular artificial puncta. In summary, our current study provides a useful guide for choosing appropriate RFP for labeling secretory membrane proteins. Among RFPs tested, mOrange2 is highly recommended based on excellent monomeric property, appropriate pKa and high brightness.

    Anthropogenic changes in land use/cover have altered the vegetation, soil, and carbon (C) cycling on the Qinghai–Tibetan Plateau (QTP) over the last ~ 50 years. As a result, the Grain for Green Program (GfGP) has been widely implemented over the last 10 years to mitigate the impacts of cultivation. To quantify the effects of the GfGP on C partitioning and turnover rates at the ecosystem scale, an in situ {sup 13}C pulse labeling experiment was conducted on natural and GfGP grasslands in an agro-pastoral ecotone in the Lake Qinghai region on the QTP. We found that there were significant differences in the C stocks of all the considered pools in both the natural and GfGP grasslands, with higher CO{sub 2} uptake rates in the GfGP grassland than that in the natural grassland. Partitioning of photoassimilate (% of recovered {sup 13}C) in C pools of both grasslands was similar 25 days after labeling, except in the roots of the 0–15 and 5–15 cm soil layer. Soil organic C (SOC) sequestration rate in the GfGP grassland was 11.59 ± 1.89 g C m{sup −2} yr{sup −1} significantly greater than that in the natural grassland. The results confirmed that the GfGP is an efficient approach for grassland restoration and C sequestration. However, it will take more than a century (119.19 ± 20.26 yr) to restore the SOC stock from the current cropland baseline level to the approximate level of natural grassland. We suggest that additional measures are needed in the selection of suitable plant species for vegetation restoration, and in reasonable grazing management. - Highlights: • Grain for Green Project initiated in 1999 converts cropland to grassland/shrubland. • Impact of Grain for Green on carbon cycling on Qinghai–Tibetan Plateau is unknown. • Effects on carbon partitioning and turnover were accessed by {sup 13}CO{sub 2} pulse labeling. • Different mass of {sup 13}C in excess, similar {sup 13}C partitioning are shown in grasslands. • Soil organic carbon of

    Accurate segmentation of anatomical structures in medical images is important in recent imaging based studies. In the past years, multi-atlas patch-based label fusion methods have achieved a great success in medical image segmentation. In these methods, the appearance of each input image patch is first represented by an atlas patch dictionary (in the image domain), and then the latent label of the input image patch is predicted by applying the estimated representation coefficients to the corresponding anatomical labels of the atlas patches in the atlas label dictionary (in the label domain). However, due to the generally large gap between the patch appearance in the image domain and the patch structure in the label domain, the estimated (patch) representation coefficients from the image domain may not be optimal for the final label fusion, thus reducing the labeling accuracy. To address this issue, we propose a novel label fusion framework to seek for the suitable label fusion weights by progressively constructing a dynamic dictionary in a layer-by-layer manner, where the intermediate dictionaries act as a sequence of guidance to steer the transition of (patch) representation coefficients from the image domain to the label domain. Our proposed multi-layer label fusion framework is flexible enough to be applied to the existing labeling methods for improving their label fusion performance, i.e., by extending their single-layer static dictionary to the multi-layer dynamic dictionary. The experimental results show that our proposed progressive label fusion method achieves more accurate hippocampal segmentation results for the ADNI dataset, compared to the counterpart methods using only the single-layer static dictionary.

    Toddler drinks are a growing category of drinks marketed for young children 9-36 months old. Medical experts do not recommend them, and public health experts raise concerns about misleading labeling practices. In the U.S., the toddler drink category includes two types of products: transition formulas, marketed for infants and toddlers 9-24 months; and toddler milks, for children 12-36 months old. The objective of this study was to evaluate toddler drink labeling practices in light of U.S. food labeling policy and international labeling recommendations. In January 2017, we conducted legal research on U.S. food label laws and regulations; collected and evaluated toddler drink packages, including nutrition labels and claims; and compared toddler drink labels with the same brand's infant formula labels. We found that the U.S. has a regulatory structure for food labels and distinct policies for infant formula, but no laws specific to toddler drinks. Toddler drink labels utilized various terms and images to identify products and intended users; made multiple health and nutrition claims; and some stated there was scientific or expert support for the product. Compared to the same manufacturer's infant formula labels, most toddler drink labels utilized similar colors, branding, logos, and graphics. Toddler drink labels may confuse consumers about their nutrition and health benefits and the appropriateness of these products for young children. To support healthy toddler diets and well-informed decision-making by caregivers, the FDA can provide guidance or propose regulations clarifying permissible toddler drink labels and manufacturers should end inappropriate labeling practices.

    Biological radioisotope studies suffer from a lack of sensitive measurement techniques and therefore traditionally require large amounts of labeled material to produce a measurable signal. Such quantities of materials are often significantly higher than naturally-occurring levels preventing these studies from replicating physiological conditions. AMS affords the sensitivity necessary to perform biological radioisotope studies with low levels of labeled material that preserve physiological conditions. The choice of labeled material can substantially affect the ease of interpretation and comprehensiveness of these studies. Here, the benefits and limitations of whole-cell labeling with {sup 14}C-glucose and targeted pathway labeling with {sup 14}C-nicotinic acid are discussed and compared.

    Full Text Available Eco-labeling plays an important role in international trade. It is necessary to put emphasis on the importance of eco-labels as potential barriers and potential incentives for international trade. Demand for products with eco-labels is increasing. However, the use of eco-labels can lead to discrimination against foreign products in the domestic market. The paper points out the great importance of the World Trade Organization and the International Organization for Standardization in the field of eco-labeling and international trade.

Our work is motivated by the close correspondence between Levy's labelled lambda-calculus and paths in proof-nets, which played an important role in the understanding of the Geometry of Interaction. The structure of the labels in Levy's labelled lambda-calculus relates to the multiplicative information of paths; the novelty of our work is that we design labelled explicit substitution calculi that also keep track of exponential information present in call-by-value and call-by-name translations of the lambda-calculus into linear logic proof-nets.

    2017-06-01

    Full Text Available An important goal of fisheries management is to ensure that fish stocks are harvested at sustainable levels of fishing pressure. However, the classical maximum sustainable yield theory and its derivatives have not worked for fisheries management. A number of mitigating measures have been suggested of which eco -labeling is one. An ecolabel on a fish product is a distinctive mark or statement indicating that it has been harvested in compliance with preset sustainability standards. This paper examines eco labeling in fisheries as the new strategy to achieve fisheries conservation and sustainability. It emphasizes the importance of fish as critical food resources and new approach to fisheries management through the use of certification programs. It considers the benefits and problems that may accrue from eco-certification of fish harvesting and trade practices in fisheries. This paper, attention is focused on examining the likely option for development of eco-labeling scheme in Nigeria. The paper concludes that the increase awareness amongst stakeholders of the potential role of eco-labeling in conservation and sustainability tools should be established.   Keywords: Fisheries management, fish, conservation, eco-certification

    Labeling instances by domain experts for classification is often time consuming and expensive. To reduce such labeling efforts, we had proposed the application of active learning (AL) methods, introduced our CAESAR-ALE framework for classifying the severity of clinical conditions, and shown its significant reduction of labeling efforts. The use of any of three AL methods (one well known [SVM-Margin], and two that we introduced [Exploitation and Combination_XA]) significantly reduced (by 48% to 64%) condition labeling efforts, compared to standard passive (random instance-selection) SVM learning. Furthermore, our new AL methods achieved maximal accuracy using 12% fewer labeled cases than the SVM-Margin AL method. However, because labelers have varying levels of expertise, a major issue associated with learning methods, and AL methods in particular, is how to best to use the labeling provided by a committee of labelers. First, we wanted to know, based on the labelers' learning curves, whether using AL methods (versus standard passive learning methods) has an effect on the Intra-labeler variability (within the learning curve of each labeler) and inter-labeler variability (among the learning curves of different labelers). Then, we wanted to examine the effect of learning (either passively or actively) from the labels created by the majority consensus of a group of labelers. We used our CAESAR-ALE framework for classifying the severity of clinical conditions, the three AL methods and the passive learning method, as mentioned above, to induce the classifications models. We used a dataset of 516 clinical conditions and their severity labeling, represented by features aggregated from the medical records of 1.9 million patients treated at Columbia University Medical Center. We analyzed the variance of the classification performance within (intra-labeler), and especially among (inter-labeler) the classification models that were induced by using the labels provided by seven

    2014-06-01

    We derive an easy-to-implement and efficient algorithm for solving multi-label image partitioning problems in the form of the problem addressed by Region Competition. These problems jointly determine a parameter for each of the regions in the partition. Given an estimate of the parameters, a fast approximate solution to the multi-label sub-problem is derived by a global update that uses smoothing and thresholding. The method is empirically validated to be robust to fine details of the image that plague local solutions. Further, in comparison to global methods for the multi-label problem, the method is more efficient and it is easy for a non-specialist to implement. We give sample Matlab code for the multi-label Chan-Vese problem in this paper! Experimental comparison to the state-of-the-art in multi-label solutions to Region Competition shows that our method achieves equal or better accuracy, with the main advantage being speed and ease of implementation.

    Humic substances (HS) play important roles in the biotic-abiotic interactions of the root plant and soil contributing to plant adaptation to external environments. However, their mode of action on plants remains largely unknown. In this study the HS distribution in tissues of wheat seedlings was examined using tritium-labeled humic acid (HA) derived from leonardite (a variety of lignites) and microautoradiography (MAR). Preferential accumulation of labeled products from tritiated HA was found in the roots as compared to the shoots, and endodermis was shown to be the major control point for radial transport of label into vascular system of plant. Tritium was also found in the stele and xylem tissues indicating that labeled products from tritiated HA could be transported to shoot tissues via the transpiration stream. Treatment with HA lead to an increase in the content of polar lipids of photosynthetic membranes. The observed accumulation of labeled HA products in root endodermis and positive impact on lipid synthesis are consistent with prior reported observations on physiological effects of HS on plants such as enhanced growth and development of lateral roots and improvement/repairs of the photosynthetic status of plants under stress conditions.

  18. Learning from Weak and Noisy Labels for Semantic Segmentation

    KAUST Repository

    Lu, Zhiwu

    2016-04-08

    A weakly supervised semantic segmentation (WSSS) method aims to learn a segmentation model from weak (image-level) as opposed to strong (pixel-level) labels. By avoiding the tedious pixel-level annotation process, it can exploit the unlimited supply of user-tagged images from media-sharing sites such as Flickr for large scale applications. However, these ‘free’ tags/labels are often noisy and few existing works address the problem of learning with both weak and noisy labels. In this work, we cast the WSSS problem into a label noise reduction problem. Specifically, after segmenting each image into a set of superpixels, the weak and potentially noisy image-level labels are propagated to the superpixel level resulting in highly noisy labels; the key to semantic segmentation is thus to identify and correct the superpixel noisy labels. To this end, a novel L1-optimisation based sparse learning model is formulated to directly and explicitly detect noisy labels. To solve the L1-optimisation problem, we further develop an efficient learning algorithm by introducing an intermediate labelling variable. Extensive experiments on three benchmark datasets show that our method yields state-of-the-art results given noise-free labels, whilst significantly outperforming the existing methods when the weak labels are also noisy.

  19. ART-Based Neural Networks for Multi-label Classification

    Science.gov (United States)

    Sapozhnikova, Elena P.

    Multi-label classification is an active and rapidly developing research area of data analysis. It becomes increasingly important in such fields as gene function prediction, text classification or web mining. This task corresponds to classification of instances labeled by multiple classes rather than just one. Traditionally, it was solved by learning independent binary classifiers for each class and combining their outputs to obtain multi-label predictions. Alternatively, a classifier can be directly trained to predict a label set of an unknown size for each unseen instance. Recently, several direct multi-label machine learning algorithms have been proposed. This paper presents a novel approach based on ART (Adaptive Resonance Theory) neural networks. The Fuzzy ARTMAP and ARAM algorithms were modified in order to improve their multi-label classification performance and were evaluated on benchmark datasets. Comparison of experimental results with the results of other multi-label classifiers shows the effectiveness of the proposed approach.

    The U.S. Food and Drug Administration and Institute of Medicine are currently investigating front-of-package (FOP) food labelling systems to provide science-based guidance to the food industry. The present paper reviews the literature on FOP labelling and supermarket shelf-labelling systems published or under review by February 2011 to inform current investigations and identify areas of future research. A structured search was undertaken of research studies on consumer use, understanding of, preference for, perception of and behaviours relating to FOP/shelf labelling published between January 2004 and February 2011. Twenty-eight studies from a structured search met inclusion criteria. Reviewed studies examined consumer preferences, understanding and use of different labelling systems as well as label impact on purchasing patterns and industry product reformulation. The findings indicate that the Multiple Traffic Light system has most consistently helped consumers identify healthier products; however, additional research on different labelling systems' abilities to influence consumer behaviour is needed.

    The food supply is complicated and consumers are increasingly calling for labeling on food to be more informative. In particular, consumers are asking for the labeling of food derived from genetically modified organisms (GMO) based on health, safety, and environmental concerns. At issue is whether the labels that are sought would accurately provide the information desired. The present study examined consumer (n = 181) perceptions of health, safety and the environment for foods labeled organic, natural, fat free or low fat, GMO, or non-GMO. Findings indicated that respondents consistently believed that foods labeled GMO are less healthy, safe and environmentally-friendly compared to all other labels (ps GMO food. These findings may provide insight for the development of labels that provide information that consumers seek.

    2014-07-31

    Several provincial and federal bills have recommended various forms of menu labelling that would require information beyond just calories; however, the additional benefit of including sodium information is unknown. The objective of this study was to determine whether sodium information on menus helps consumers make lower-sodium choices and to understand what other factors influence the effect of menu labelling on consumers' meal choices. A total of 3,080 Canadian consumers completed an online survey that included a repeated measures experiment in which consumers were asked to select what they would typically order from four mock-restaurant menus. Subsequently, consumers were randomly allocated to see one of three menu-labelling treatments (calories; calories and sodium; or calories, sodium and serving size) and were given the option to change their order. There was a significant difference in the proportion of consumers who changed their order, varying from 17% to 30%, depending on the restaurant type. After participants had seen menu labelling, sodium levels decreased in all treatments (p<0.0001). However, in three of the four restaurant types, consumers who saw calorie and sodium information ordered meals with significantly less sodium than consumers who saw only calorie information (p<0.01). Consumers who saw sodium labelling decreased the sodium level of their meal by an average of 171-384 mg, depending on the restaurant. In the subset of consumers who saw sodium information and chose to change their order, sodium levels decreased by an average of 681-1,360 mg, depending on the restaurant. Sex, intent to lose weight and the amount of calories ordered at baseline were the most important predictors of who used menu labelling. Eighty percent of survey panelists wanted to see nutrition information when dining out. Including sodium information alongside calorie information may result in a larger decrease in the amount of sodium ordered by restaurant-goers.

    Food labels to support healthier choices are an important potential intervention for improving population health by reducing obesity and diet-related disease. This study examines the use of research evidence about traffic light nutrition labelling in submissions to the Review of Food Labelling Law and Policy conducted in Australia and New Zealand. Content analysis of final submissions to the Review and a literature review of documents reporting research evidence about traffic light labelling. Sixty-two submitters to the Review were categorised as 'supporters' of traffic light labelling and 29 as 'opponents'. Supporters focused on studies showing traffic light labels were better than other systems at helping consumers identify healthier food options. Opponents cited evidence that traffic light labels were no better than other systems in this respect and noted a lack of evidence that they led to changes in food consumption. A literature review demonstrated that, as a group, submitters had drawn attention to most of the relevant research evidence on traffic light labelling. Both supporters and opponents were, however, selective in their use of evidence. The weight of evidence suggested that traffic light labelling has strengths in helping consumers to identify healthier food options. Further research would be valuable in informing the development of an interpretive front-of-pack labelling system. The findings have significant implications for the development of front-of-pack nutrition labelling currently being considered in Australia and New Zealand. © 2012 The Authors.

    2012-02-16

    The overall goal of this project was to develop methods for the production of metal-based radionuclides, to develop metal-based radiopharmaceuticals and in a limited number of cases, to translate these agents to the clinical situation. Initial work concentrated on the application of the radionuclides of Cu, Cu-60, Cu-61 and Cu-64, as well as application of Ga-68 radiopharmaceuticals. Initially Cu-64 was produced at the Missouri University Research Reactor and experiments carried out at Washington University. A limited number of studies were carried out utilizing Cu-62, a generator produced radionuclide produced by Mallinckrodt Inc. (now Covidien). In these studies, copper-62-labeled pyruvaldehyde Bis(N{sup 4}-methylthiosemicarbazonato)-copper(II) was studied as an agent for cerebral myocardial perfusion. A remote system for the production of this radiopharmaceutical was developed and a limited number of patient studies carried out with this agent. Various other copper radiopharmaceuticals were investigated, these included copper labeled blood imaging agents as well as Cu-64 labeled antibodies. Cu-64 labeled antibodies targeting colon cancer were translated to the human situation. Cu-64 was also used to label peptides (Cu-64 octriatide) and this is one of the first applications of a peptide radiolabeled with a positron emitting metal radionuclide. Investigations were then pursued on the preparation of the copper radionuclides on a small biomedical cyclotron. A system for the production of high specific activity Cu-64 was developed and initially the Cu-64 was utilized to study the hypoxic imaging agent Cu-64 ATSM. Utilizing the same target system, other positron emitting metal radionuclides were produced, these were Y-86 and Ga-66. Radiopharmaceuticals were labeled utilizing both of these radionuclides. Many studies were carried out in animal models on the uptake of Cu-ATSM in hypoxic tissue. The hypothesis is that Cu-ATSM retention in vivo is dependent upon the

    The global pandemic of obesity and overweight now affects between 2.8 and 3.5 billion of the world population and shows no signs of abatement. Treatment for what is now recognized as a chronic disease includes pharmacotherapy, considered an essential component of comprehensive therapy. New drug discovery is robust, but the pace of the US Food and Drug Administration approval for obesity drugs has been glacial, and only a handful of approved drugs are available for treating obesity. In the last 20 years, the US Food and Drug Administration has approved 208 drugs for cancer, 118 for cardiovascular diseases, 168 for neurological diseases, and 223 endocrinologic drugs, but only 6 for obesity, 2 of which have been taken off market. Currently, there are only 9 drugs approved by the FDA for obesity treatment. US physicians have turned to off-label drug use in their effort to care for increasing numbers of patients with excess adiposity. Phentermine is the most commonly used drug for treating obesity. Although approved only for short-term use, US physicians have used it successfully for long-term since its initial approval in 1959. This drug, used off-label for long-term, has proven to be safe and effective, far safer than the disease it is used to treat. Phentermine and diethylpropion, an equally safe but somewhat less effective drug, are both generic and therefore inexpensive. These drugs have been maligned inappropriately because their two-dimensional structure diagrams resemble amphetamine and also because of unproven presumptions about their potential adverse effects. In the face of an increasing epidemic, worldwide obese and overweight patients deserve effective treatment that prescribing these drugs could provide, if rehabilitated and used more frequently. US physicians will likely continue to use any drug proven useful off-label for this illness until such time as more effective drugs are approved. PMID:28652791

    Recombinant adenovirus type 5 particles (AdCMVLuc) were labeled with two different bifunctional ligands capable of forming stable complexes with paramagnetic lanthanide ions. The number of covalently attached ligands varied between 630 and 1960 per adenovirus particle depending upon the chemical reactivity of the bifunctional ligand (NHS ester versus isothiocyanide), the amount of excess ligand added, and the reaction time. The bioactivity of each labeled adenovirus derivative, as measured by the ability of the virus to infect cells and express luciferase, was shown to be highly dependent upon the number of covalently attached ligands. This indicates that certain amino groups, likely on the surface of the adenovirus fiber protein where cell binding is known to occur, are critical for viral attachment and infection. Addition of 177Lu3+ to chemically modified versus control viruses demonstrated a significant amount of nonspecific binding of 177Lu3+ to the virus particles that could not be sequestered by addition of excess DTPA. Thus, it became necessary to implement a prelabeling strategy for conjugation of preformed lanthanide ligand chelates to adenovirus particles. Using preformed Tm3+-L2, a large number of chelates having chemical exchange saturation transfer (CEST) properties were attached to the surface residues of AdCMVLuc without nonspecific binding of metal ions elsewhere on the virus particle. The potential of such conjugates to act as PARACEST imaging agents was tested using an on-resonance WALTZ sequence for CEST activation. A 12% decrease in bulk water signal intensity was observed relative to controls. This demonstrates that viral particles labeled with PARACEST-type imaging agents can potentially serve as targeted agents for molecular imaging. PMID:18254605

    Full Text Available Abstract Background Automatic semantic role labeling (SRL is a natural language processing (NLP technique that maps sentences to semantic representations. This technique has been widely studied in the recent years, but mostly with data in newswire domains. Here, we report on a SRL model for identifying the semantic roles of biomedical predicates describing protein transport in GeneRIFs – manually curated sentences focusing on gene functions. To avoid the computational cost of syntactic parsing, and because the boundaries of our protein transport roles often did not match up with syntactic phrase boundaries, we approached this problem with a word-chunking paradigm and trained support vector machine classifiers to classify words as being at the beginning, inside or outside of a protein transport role. Results We collected a set of 837 GeneRIFs describing movements of proteins between cellular components, whose predicates were annotated for the semantic roles AGENT, PATIENT, ORIGIN and DESTINATION. We trained these models with the features of previous word-chunking models, features adapted from phrase-chunking models, and features derived from an analysis of our data. Our models were able to label protein transport semantic roles with 87.6% precision and 79.0% recall when using manually annotated protein boundaries, and 87.0% precision and 74.5% recall when using automatically identified ones. Conclusion We successfully adapted the word-chunking classification paradigm to semantic role labeling, applying it to a new domain with predicates completely absent from any previous studies. By combining the traditional word and phrasal role labeling features with biomedical features like protein boundaries and MEDPOST part of speech tags, we were able to address the challenges posed by the new domain data and subsequently build robust models that achieved F-measures as high as 83.1. This system for extracting protein transport information from Gene

    Fluorescent semiconductor quantum dots that can serve as "on/off" labels for bacteria and other living cells are undergoing development. The "on/off" characterization of these quantum dots refers to the fact that, when properly designed and manufactured, they do not fluoresce until and unless they come into contact with viable cells of biological species that one seeks to detect. In comparison with prior fluorescence-based means of detecting biological species, fluorescent quantum dots show promise for greater speed, less complexity, greater sensitivity, and greater selectivity for species of interest. There are numerous potential applications in medicine, environmental monitoring, and detection of bioterrorism.

    Biotechnology has the potential to introduce new food safety risks, liabilities and benefits, and although privately managed supply chains (involving proactive management of the production of branded products) are effective at providing, managing and communicating adequate information about products with well understood risks, products with uncertain risks pose a greater challenge. The demand for increased product information regarding genetically modified content, in particular, places new constraints on food supply chains, frequently resulting in communication failures. Here we assess and reject mandatory labeling as an appropriate response.

    Full Text Available Background: Considering the significant role of consumers’ awareness about food labels in making healthy food choices, this study was designed to assess the knowledge, attitude and prac-tice of university students about food labeling.Methods: In this cross-sectional study, 332 students aged 18-25 yr in five different academic ma-jors (including Nutrition, Public Health, Health Services Administration, Paramedical and En-gineering were asked to complete an approved questionnaire contained fifteen questions. The chi-square test was applied to examine the differences across various major groups.Results: 89.2% of the students believed that food labels had effect on nutritional awareness. 77.4% were agreed with the usefulness of the food labels and 79.2% did not feel that nutrition claims on food label were truthful. For 84% of students, the expiry date and storage conditions information were the most important informational cues to appear on the food labels. From 47.6% of students who reported the use of nutrition facts label in their often or always shopping; only 32.3% used the information on labels to fit the food into their daily diet. Surprisingly, fatty acids were the least noteworthy items (1.9% on nutrition facts labels. Regarding students’ major, there was significant difference in their knowledge, attitude and practice about truth of the nutri-tion claims, using food labels and importance of health claims (P<0.05.Conclusion: Food labels were more useful tools for students and had an effect on their nutri-tional awareness. Designing and implementation of the educational programs in order to increase the level of knowledge about food labels is suggested.

    Nutrition information on packaged foods supplies information that aids consumers in meeting the recommendations put forth in the US Dietary Guidelines for Americans such as reducing intake of solid fats and added sugars. It is important to understand how food label use is related to dietary intake. However, prior work is based only on self-reported use of food labels, making it unclear if subjective assessments are biased toward motivational influences. We assessed food label use using both self-reported and objective measures, the stage of change, and dietary quality in a sample of 392 stratified by income. Self-reported food label use was assessed using a questionnaire. Objective use was assessed using a mock shopping task in which participants viewed food labels and decided which foods to purchase. Eye movements were monitored to assess attention to nutrition information on the food labels. Individuals paid attention to nutrition information when selecting foods to buy. Self-reported and objective measures of label use showed some overlap with each other (r=0.29, pfood label use. These data show both self-reported and objective measures of food label use are positively associated with dietary quality. However, self-reported measures appear to capture a greater motivational component of food label use than do more objective measures.

    Food allergic consumers depend on ingredient labels for allergen avoidance, and the modality of labeling is changing. To investigate current responses to food labels so that the impact of future label changes can be anticipated. Adults who attended Food Allergy & Anaphylaxis Network conferences completed a survey regarding their experiences with food labels for their family's most severely affected food allergic individual (FAI). There were 489 completed surveys (84% participation). Most FAIs were young (41% allergies included the following: peanut, 81%; tree nuts, 53%; milk, 51%; egg, 51%; and soy, 17%. All chocolate products were avoided by 37% of FAIs who were avoiding peanut and 40% who were avoiding tree nuts; 91% of tree nut allergic FAIs avoided all tree nuts. Of FAIs who avoided soy, 41% avoided soybean oil and 38% avoided soy lecithin. Of those who avoided milk, 82% avoided lactose. Allergic reactions were attributed to misunderstanding label terms (16%) and to nonspecific terms (spice, flavor) (22%). Ingredient labels were "always" or "frequently" read before purchase by 99%. Product brand choice was "very much influenced" by the manner of labeling for 86%, and manufacturers were contacted for more information by 86%. Our results suggest that improved product allergen labeling will reduce allergic reactions and simplify allergy management. However, the new labeling may not indicate the form or source of the allergen, and individuals who do not currently avoid foods with minimal or irrelevant protein content, such as soy oil or soy lecithin, may face additional ambiguity and unnecessary dietary restrictions.

    The Family Smoking Prevention and Control Act gave the U.S. Food and Drug Administration (FDA) legal authority to mandate graphic warning labels on cigarette advertising and packaging. The FDA requires that these graphic warning labels be embedded into cigarette advertising and packaging by September 2012. The aim of this study was to examine differences in recall and viewing patterns of text-only versus graphic cigarette warning labels and the association between viewing patterns and recall. Participants (current daily smokers; N=200) were randomized to view a cigarette advertisement with either text-only or graphic warning labels. Viewing patterns were measured using eye-tracking, and recall was later assessed. Sessions were conducted between November 2008 and November 2009. Data analysis was conducted between March 2011 and July 2011. There was a significant difference in percentage correct recall of the warning label between those in the text-only versus graphic warning label condition, 50% vs 83% (χ(2)=23.74, p=0.0001). Time to first viewing of the graphic warning label text and dwell time duration (i.e., time spent looking) on the graphic image were significantly associated with correct recall. Warning labels that drew attention more quickly and resulted in longer dwell times were associated with better recall. Graphic warning labels improve smokers' recall of warning and health risks; these labels do so by drawing and holding attention. Copyright © 2012 American Journal of Preventive Medicine.

    Recently, multi-atlas patch-based label fusion has achieved many successes in medical imaging area. The basic assumption in the current state-of-the-art approaches is that the image patch at the target image point can be represented by a patch dictionary consisting of atlas patches from registered atlas images. Therefore, the label at the target image point can be determined by fusing labels of atlas image patches with similar anatomical structures. However, such assumption on image patch representation does not always hold in label fusion since (1) the image content within the patch may be corrupted due to noise and artifact; and (2) the distribution of morphometric patterns among atlas patches might be unbalanced such that the majority patterns can dominate label fusion result over other minority patterns. The violation of the above basic assumptions could significantly undermine the label fusion accuracy. To overcome these issues, we first consider forming label-specific group for the atlas patches with the same label. Then, we alter the conventional flat and shallow dictionary to a deep multi-layer structure, where the top layer (label-specific dictionaries) consists of groups of representative atlas patches and the subsequent layers (residual dictionaries) hierarchically encode the patchwise residual information in different scales. Thus, the label fusion follows the representation consensus across representative dictionaries. However, the representation of target patch in each group is iteratively optimized by using the representative atlas patches in each label-specific dictionary exclusively to match the principal patterns and also using all residual patterns across groups collaboratively to overcome the issue that some groups might be absent of certain variation patterns presented in the target image patch. Promising segmentation results have been achieved in labeling hippocampus on ADNI dataset, as well as basal ganglia and brainstem structures, compared

    EPR long-range distance measurements on spin-labeled macromolecules have recently become a popular tool in structural biology. The method can be used to obtain coarse-grained structures of biomolecules, to track conformational changes and dynamics, to dock macromolecular complexes, or to localize spin centers within macromolecules using trilateration. Because the conformation of the spin label is usually unknown, it is often necessary to construct conformational models of the spin label on the macromolecules for data interpretation. For this purpose, so-called in silico spin-labeling approaches have been developed. In this chapter, a comprehensive summary of the mtsslSuite is provided, one of the in silico spin-labeling software packages. The package currently contains three programs: mtsslWizard, mtsslDock, and mtsslTrilaterate. Worked examples for the usage of all three programs during the planning- and interpretation stages of the EPR experiment are given. © 2015 Elsevier Inc. All rights reserved.

    Use of nutritional labels in choosing food is associated with healthier eating habits including lower fat intake. Current public health efforts are focusing on the revamping of nutritional labels to make them easier to read and use for the consumer. The study aims to assess the frequency of use of nutritional labels and awareness of the United States Department of Agriculture (USDA) nutritional programmes by low-income women including those participating in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) as surveyed in the National Health and Nutrition Examination Survey 2005-2006. Many low-income women do not regularly use the nutrition facts panel information on the food label and less than half had heard of the USDA Dietary Guidelines for Americans (38.9%). In multivariate logistic regression, we found that WIC participation was associated with reduced use of the nutrition facts panel in choosing food products [odds ratio (OR) 0.45, 95% confidence interval (CI) 0.22-0.91], the health claims information (OR 0.54, 95% CI 0.32-0.28) and the information on carbohydrates when deciding to buy a product (OR 0.44, 95% CI 0.20-0.97) in comparison with WIC eligible non-participants. Any intervention to improve use of nutritional labels and knowledge of the USDA's nutritional programmes needs to target low-income women, including WIC participants. Future studies should evaluate possible reasons for the low use of nutrition labels among WIC participants in comparison with eligible non-participants. © 2011 John Wiley & Sons Ltd.

    The Fuel Economy Label and CAFE Data asset contains measured summary fuel economy estimates and test data for light-duty vehicle manufacturers by model for certification as required under the Energy Policy and Conservation Act of 1975 (EPCA) and The Energy Independent Security Act of 2007 (EISA) to collect vehicle fuel economy estimates for the creation of Economy Labels and for the calculation of Corporate Average Fuel Economy (CAFE). Manufacturers submit data on an annual basis, or as needed to document vehicle model changes.The EPA performs targeted fuel economy confirmatory tests on approximately 15% of vehicles submitted for validation. Confirmatory data on vehicles is associated with its corresponding submission data to verify the accuracy of manufacturer submissions beyond standard business rules. Submitted data comes in XML format or as documents, with the majority of submissions being sent in XML, and includes descriptive information on the vehicle itself, fuel economy information, and the manufacturer's testing approach. This data may contain proprietary information (CBI) such as information on estimated sales or other data elements indicated by the submitter as confidential. CBI data is not publically available; however, within the EPA data can accessed under the restrictions of the Office of Transportation and Air Quality (OTAQ) CBI policy [RCS Link].

    While cilia are recognized as important signaling organelles, the extent of ciliary functions remains unknown because of difficulties in cataloguing proteins from mammalian primary cilia. We present a method that readily captures rapid snapshots of the ciliary proteome by selectively biotinylating ciliary proteins using a cilia-targeted proximity labeling enzyme (cilia-APEX). Besides identifying known ciliary proteins, cilia-APEX uncovered several ciliary signaling molecules. The kinases PKA, AMPK, and LKB1 were validated as bona fide ciliary proteins and PKA was found to regulate Hedgehog signaling in primary cilia. Furthermore, proteomics profiling of Ift27/Bbs19 mutant cilia correctly detected BBSome accumulation inside Ift27(-/-) cilia and revealed that β-arrestin 2 and the viral receptor CAR are candidate cargoes of the BBSome. This work demonstrates that proximity labeling can be applied to proteomics of non-membrane-enclosed organelles and suggests that proteomics profiling of cilia will enable a rapid and powerful characterization of ciliopathies.

    2014-01-01

    Due to expanding applications of positron emission tomography (PET) there is a demand for developing new techniques to introduce fluorine-18 (t 1/2 = 109.8 min). Considering that most novel PET tracers are sensitive biomolecules and that direct introduction of fluorine-18 often needs harsh conditions, the insertion of 18F in those molecules poses an exceeding challenge. Two major challenges during 18F-labeling are a regioselective introduction and a fast and high yielding way under mild conditions. Furthermore, attention has to be paid to functionalities, which are usually present in complex structures of the target molecule. The Cu-catalyzed azide-alkyne cycloaddition (CuAAC) and several copper-free click reactions represent such methods for radiolabeling of sensitive molecules under the above-mentioned criteria. This minireview will provide a quick overview about the development of novel 18F-labeled prosthetic groups for click cycloadditions and will summarize recent trends in copper-catalyzed and copper-free click 18F-cycloadditions.

    2013-09-01

    Approval of a drug for clinical use requires production of data on efficacy and safety through submission of results from randomized controlled trials (RCTs), in which the new molecule is usually compared with placebo (or an active comparator) for a set of outcomes that will serve as the basis for the drug's indications. These indications are crucial, because drugs are approved on the basis of their net clinical benefit for specific and well-defined diseases and--importantly--only for these. Once the drug is available for use in tens or hundreds of thousands of patients, physicians may realize that some medications can be effective in diseases for which they were not approved, i.e., no studies have been presented to the regulatory authorities, and therefore they are not formally approved for those indications. Convinced of the benefits for their patients, some physicians prescribe them for unapproved indications--off-label prescription. In this paper we discuss the prevalence of off-label prescription, and its advantages and problems. Copyright © 2012 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

    2013-10-01

    Metabolic labeling of biomolecules with bioorthogonal functionalities enables visualization, enrichment, and analysis of the biomolecules of interest in their physiological environments. This versatile strategy has found utility in probing various classes of biomolecules in a broad range of biological processes. On the other hand, metabolic labeling is nonselective with respect to cell type, which imposes limitations for studies performed in complex biological systems. Herein, we review the recent methodological developments aiming to endow metabolic labeling strategies with cell-type selectivity. The cell-selective metabolic labeling strategies have emerged from protein and glycan labeling. We envision that these strategies can be readily extended to labeling of other classes of biomolecules.

    2014-01-01

    Full Text Available The legal regulation of genetically modified food directly affects consumers, since they are the ones who encounter genetically modified food on the shelves every day. At the beginning, authors indicate that there are huge differences between legal regulation of genetically modified food in the United States and in the European Union. These differences result in different labeling regimes in those two systems of genetically modified food regulation. Authors consider several factors from which depend efficiency of the labeling regime, and labels' influence on the actual realization of basic consumers' rights. Authors will analyze these factors in the paper, such as: label complexity, opting for positive or negative labeling regime, whether labeling regime is mandatory or voluntary, etc. In the conclusion authors give recommendations to the Serbian legislator, and propositions for changes in current domestic legal regulation, which would improve realization of basic consumers' rights in relation with genetically modified food.

    2016-03-01

    In response to high rates of obesity in the USA, several American cities, counties, and states have passed laws requiring restaurant chains to post labels identifying the energy content of items on menus, and nationwide implementation of menu labeling is expected in late 2016. In this review, we identify and summarize the results of 16 studies that have assessed the impact of real-world numeric calorie posting. We also discuss several controversies surrounding the US Food and Drug Administration's implementation of federally mandated menu labeling. Overall, the evidence regarding menu labeling is mixed, showing that labels may reduce the energy content of food purchased in some contexts, but have little effect in other contexts. However, more data on a range of ong-term consumption habits and restaurant responses is needed to fully understand the impact menu labeling laws will have on the US population's diet.

    2017-08-01

    Symbolic interactionism argues that the effect of informal labeling by general others, such as family and friends, on behavior depends on the social context under which labeling takes place. Despite abundant research on informal labeling, little effort has been made to contextualize its impact on adolescent reoffending. Also, compared with other theories, only a few studies have been conducted among youths in Asian population. Using three consecutive waves of self-reported survey data from a nationally representative sample of 2,406 Korean adolescents, this study examined an interactional model for the informal labeling effect. Findings suggest that informal labeling, as well as school commitment and delinquent peer association, has an independent effect on delinquency. Also supported is the symbolic interactionist hypothesis that adolescents with greater involvement in delinquent subcultures were less susceptible to informal labeling. Implications of the findings are discussed.

    Most studies dealing with the utilization of {sup 15} N labeled plant material do not present details about the labeling technique. This is especially relevant for legume species since biological nitrogen fixation difficult plant enrichment. A technique was developed for labeling leguminous plant tissue with {sup 15} N to obtain labeled material for nitrogen dynamics studies. Sun hemp (Crotalaria juncea L.) was grown on a Paleudalf, under field conditions. An amount of 58.32 g of urea with 70.57{+-} 0.04 atom % {sup 15} N was sprayed three times on plants grown on eight 6-m2-plots. The labelled material presented 2.412 atom % {sup 15} N in a total dry matter equivalent to 9 Mg ha{sup -1} This degree of enrichment enables the use of the green manure in pot or field experiments requiring {sup 15} N-labeled material.

    2014-06-01

    Purpose: It is often assumed that animal biodistributions of novel proteins are not dependent upon the radiolabel used in their determination. In units of percent injected dose per gram of tissue (%ID/g), organ uptake results (u) may be obtained using either iodine or metal as radioactive labels. Iodination is preferred as it is a one-step process whereas metal labeling requires two chemical procedures and therefore more protein material. It is important to test whether the radioactive tag leads to variation in the uptake value. Methods: Uptakes of 3antibodies to Carcinoembryonic Antigen (CEA) were evaluated in a nude mouse model bearing 150 to 300 mg LS174T human colon cancer xenografts. Antibodies included diabody (56 kDa), minibody (80kDa) and intact M5A (150 kDa) anti-CEA cognates. Both radioiodine and indium-111 labels were used with uptakes evaluated at 7 time(t) points out to 96 h. Ratios (R) of u(iodine-label)/u(indium-label) were determined for liver, spleen, kidneys, lung and tumor. Results: Hepatic loss was rapid for diabody and minibody; by 24 h their R values were only 2%; i.e., uptake of iodine was 2% of that of indium for these 2 antibodies. By contrast, R for the intact cognate was 50% at that time point. Splenic results were similar. Tumor uptake ratios did not depend upon the antibody type and were 50% at 24 h. Conclusions: Relatively rapid loss of iodine relative to indium in liver and spleen was observed in lower mass antibodies. Tumor ratios were larger and independent of antibody type. Aside from tumor, the R ratio of uptakes depended on the antibody type. R values decreased monotonically with time in all tissues and for all cognates. Using this ratio, one can possibly correct iodine-based u (t) results so that they resemble radiometal-derived biodistributions.

    Direct bromination of the tyrosine residues of peptides and antibodies with bromine-76, to create probes for PET imaging, has been reported. For peptides that do not contain tyrosine residues, however, a prosthetic group is required to achieve labeling via conjugation to other functional groups such as terminal α-amines or lysine ε-amines. The goal of this study was to develop new strategies for labeling small peptides with Br-76 using either a direct labeling method or a prosthetic...
