    In the wake of the recent financial crisis, over-the-counter (OTC) derivatives have been blamed for increasing systemic risk. Although OTC derivatives were not a central cause of the crisis, the complexity and limited transparency of the market reinforced the potential for excessive risk-taking, as regulators did not have a clear view into how OTC derivatives were being used. We discuss how the New York Fed and other regulators could improve weaknesses in the OTC derivatives market through st...

    Takano-Ohmuro, Hiromi; Nakajima, Yayoi; Saito, Mitsuo; Yuda, Yasukatsu

    2016-01-01

    Kampo medicines must be used according to an individual's physical characteristics and symptoms to avoid lack of efficacy, adverse reactions or interactions with other drugs. As category-2 over-the-counter drugs (OTCs), Kampo OTCs are not targets of active explanations by pharmacists, and consumers usually decide to use OTCs by themselves on the basis of drug label information. However, information on the label is occasionally brief. To promote the proper use of Kampo OTCs, we herein propose an informative tool based on the Australian Shelf-Talker (information on the proper use of OTCs with a self-check questionnaire for consumers), the Self-Check Card (SCC). We also prepared the informative material, Information to the Pharmacist (IP), directed at pharmacists regarding these Kampo OTCs. We created SCCs and IPs for 16 prescriptions in the 5 most demanded categories (cold, cough/sore throat, urination problems, women's diseases, and shoulder stiffness or joint/nerve pain). The SCC with questions in a simplified language specifies individuals who should avoid the drug, or those who should consult a pharmacist before purchase, according to the safety information on the respective drug labels. The IP provides information to pharmacists on safety issues and those concerning recognition of the consumer's symptoms and physical characteristics needed for the selection of appropriate Kampo OTCs. Such SCCs and IPs are now in use in 2 pharmacies to know pharmacists' suggestions about improvements and consumer's opinions and degree of satisfaction. We believe these risk-benefit communication tools, SCC and IP, will contribute to improve the proper use of Kampo OTCs. PMID:26831805

    Earlier this year, tamsulosin, an alpha blocker previously only available on prescription, became available for sale by pharmacists as a treatment for functional symptoms of benign prostatic hyperplasia (BPH) in men aged 45-75 years (Flomax Relief MR - Boehringer Ingelheim). A television advert for the over-the-counter (OTC) product claims that it is a "simple and effective" treatment that can relieve symptoms within 1 week, allowing the user to "take control of your annoying pee problems".¹ Here we review the evidence on tamsulosin and assess whether its availability as an OTC product confers worthwhile advantages.

  18. Association of Risk Perception and Information Provided on the Labels of Over-the-Counter Drugs: Role of Race, Education, Age and Income

    Directory of Open Access Journals (Sweden)

    Sunil Mathur

    2014-01-01

    Full Text Available Background: The use of over-the-counter (OTC drugs has increased tremendously, however, information on risk perception regarding the use of OTC drugs and their potential toxicity is scarce. Hence, the purpose of this study was to investigate the perception of OTC drug safety and efficacy based on reading product packaging and the effect of race, education, age and income. Methods: We used the HINTS 2012 data set with total sample size of 2,554. Results: OTC drug users having some high school education had a lower chance of frequently reading information included in the product labeling with the OTC medication. OTC drug users less than 50 years of age were always likely to read drug information on the OTC drug labeling. Also, Non-Hispanic blacks were more likely to read OTC drug labeling than Non-Hispanic whites.  OTC drug users less than 50 years of age consider OTC drugs safer than prescription drugs.  Conversely, OTC drug users with a high school, some college or bachelor’s degree consider OTC drugs less safe than prescription drugs.  Non-Hispanic blacks, non-Hispanic whites, and subjects of lower income were less likely to consider OTC drugs safer than prescription drugs.  OTC drug users with a high school education and some college perceive OTC drugs to be less effective than prescription drugs.Conclusion: To conclude, age, education, race, and income affect risk perception on OTC drugs.  Consumer information programs need to be designed so that meaningful results can be incorporated into public policy. Providing information on the labeling of OTC drugs and likelihood of patients reading this information require further study.

  20. EnzML: multi-label prediction of enzyme classes using InterPro signatures

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Abstract Background Manual annotation of enzymatic functions cannot keep up with automatic genome sequencing. In this work we explore the capacity of InterPro sequence signatures to automatically predict enzymatic function. Results We present EnzML, a multi-label classification method that can efficiently account also for proteins with multiple enzymatic functions: 50,000 in UniProt. EnzML was evaluated using a standard set of 300,747 proteins for which the manually curated Swiss-Prot and KEGG databases have agreeing Enzyme Commission (EC annotations. EnzML achieved more than 98% subset accuracy (exact match of all correct Enzyme Commission classes of a protein for the entire dataset and between 87 and 97% subset accuracy in reannotating eight entire proteomes: human, mouse, rat, mouse-ear cress, fruit fly, the S. pombe yeast, the E. coli bacterium and the M. jannaschii archaebacterium. To understand the role played by the dataset size, we compared the cross-evaluation results of smaller datasets, either constructed at random or from specific taxonomic domains such as archaea, bacteria, fungi, invertebrates, plants and vertebrates. The results were confirmed even when the redundancy in the dataset was reduced using UniRef100, UniRef90 or UniRef50 clusters. Conclusions InterPro signatures are a compact and powerful attribute space for the prediction of enzymatic function. This representation makes multi-label machine learning feasible in reasonable time (30 minutes to train on 300,747 instances with 10,852 attributes and 2,201 class values using the Mulan Binary Relevance Nearest Neighbours algorithm implementation (BR-kNN.

  1. Issues and Prospects from the OTC Industry vis a vis Pharmaceutical Education and OTC Medicines.

    2016-01-01

    In the amendment of the Pharmaceutical Affairs Law in 2013, a new category, Pharmacist Intervention Required Medicines (PIRM), was introduced, and other OTC medicines, which were classified after the 2006 amendment, were allowed to be sold via the Internet. Regarding PIRM, Japan's Ministry for Health, Labour and Welfare designates medicines which require special intervention by a pharmacist who explains their proper use to a patient through a face-to-face consultation, wherein the pharmacist provides guidance based on pharmaceutical knowledge and experience. This encourages consumers to approach their longer term personal healthcare with a rational knowledge of medicines, and dovetails with the direction described in "Japan is Back". Along with the 2006 amendment, an upgraded 6-year curriculum for the study of pharmacy in preparation for becoming a pharmacist was introduced. This allows student pharmacists to have more experience working in community pharmacies, thus supporting and providing pharmacists with the knowledge they need to better help the consumer to rationally use OTC medicines and self-select proper OTC medications. And this is not only restricted to OTC medicines, as there are many items sold in local pharmacies available to be utilized by the consumer with reasonable support by pharmacists. There is an expectation that the pharmacist be prepared to assist the consumer not only with prescriptions, but also with OTC medications, supplements, medical accessories, etc. using their knowledge and experience.

    Sansgiry, S S; Cady, P S

    1997-01-01

    Currently, marketed over-the-counter (OTC) medication labels were simulated and tested in a controlled environment to understand consumer evaluation of OTC label information. Two factors, consumers' age (younger and older adults) and label designs (picture-only, verbal-only, congruent picture-verbal, and noncongruent picture-verbal) were controlled and tested to evaluate consumer information processing. The effects exerted by the independent variables, namely, comprehension of label information (understanding) and product evaluations (satisfaction, certainty, and perceived confusion) were evaluated on the dependent variable purchase intention. Intention measured as purchase recommendation was significantly related to product evaluations and affected by the factor label design. Participants' level of perceived confusion was more important than actual understanding of information on OTC medication labels. A Label Evaluation Process Model was developed which could be used for future testing of OTC medication labels. PMID:10168485

    Atherosclerotic plaque composition can indicate plaque vulnerability. We segment atherosclerotic plaque components from the carotid artery on a combination of in vivo MRI and CT-angiography (CTA) data using supervised voxelwise classification. In contrast to previous studies the ground truth for training is directly obtained from 3D registration with histology for fibrous and lipid-rich necrotic tissue, and with μCT for calcification. This registration does, however, not provide accurate voxelwise correspondence. We therefore evaluate three approaches that incorporate uncertainty in the ground truth used for training: I) soft labels are created by Gaussian blurring of the original binary histology segmentations to reduce weights at the boundaries between components, and are weighted by the estimated registration accuracy of the histology and in vivo imaging data (measured by overlap), II) samples are weighted by the local contour distance of the lumen and outer wall between histology and in vivo data, and III) 10% of each class is rejected by Gaussian outlier rejection. Classification was evaluated on the relative volumes (% of tissue type in the vessel wall) for calcified, fibrous and lipid-rich necrotic tissue, using linear discriminant (LDC) and support vector machine (SVM) classification. In addition, the combination of MRI and CTA data was compared to using only one imaging modality. Best results were obtained by LDC and outlier rejection: the volume error per vessel was 0.9±1.0% for calcification, 12.7±7.6% for fibrous and 12.1±8.1% for necrotic tissue, with Spearman rank correlation coefficients of 0.91 (calcification), 0.80 (fibrous) and 0.81 (necrotic). While segmentation using only MRI features yielded low accuracy for calcification, and segmentation using only CTA features yielded low accuracy for necrotic tissue, the combination of features from MRI and CTA gave good results for all studied components.

  8. Complexes of technetium-99m with tetrapeptides, a new class of 99mTc-labelled agents

    International Nuclear Information System (INIS)

    Tetrapeptides are a class of N4-tetraligands that can efficiently bind 99mTc. In fact, tetrapeptides can be considered as derivatives of mercaptoacetyltriglycine (MAG3) in which the mercaptoacetyl moiety is replaced by a more stable and easier to handle aminoacyl group. Direct labelling of tetrapeptides with99m Tc in alkaline medium (pH ≥ 11) in the presence of stannous ions gave a high yield (>95%) of one or two (probably isomeric) radiochemical species. Exchange labelling at different pH values in the presence of stannous tartrate resulted in lower yields of the same 99mTc-labelled products as those formed during direct labelling. In addition, other radiochemical species were formed of which one was characterized as an oxotechnetium-complex with the cyclisized tetrapeptide. Tetrapeptides with a chiral centre in the first amino acid yield upon labelling with 99mTc two radiochemical species, probably the two diastereomers with an oxotechnetium core respectively syn and anti with respect to the substituent on the amino acid. Only one diastereomer was observed when the chiral carbon atom is located in the second or third amino acid. Electrophoresis indicated that these new 99mTc-labelled complexes are neutral in acidic medium and negatively charged in neutral and alkaline conditions. This correlates with a complex in which an oxotechnetium(V) group is bound to the ligand through three deprotonated nitrogen atoms of the amide functions and the free electron pair of the amine nitrogen atom. Biodistribution in mice showed for all studied 99mTc-labelled tetrapeptides a rapid clearance from the blood mainly by the renal system. The presence of a methyl substituent in the tetrapeptide increased the urinary excretion. 99mTc-labelledl -glycylalanylglycylglycine showed in mice a urinary excretion comparable to that of 99mTc-MAG3. Further rise of lipophilicity by introduction of a dimethyl, isopropyl or isobutyryl group leads to increased hepatobiliary handling. It is

    2003-02-01

    We report the development, validation, and application of competition-based peptide binding assays for 13 prevalent human leukocyte antigen (HLA) class I alleles. The assays are based on peptide binding to HLA molecules on living cells carrying the particular allele. Competition for binding between the test peptide of interest and a fluorescein-labeled HLA class I binding peptide is used as read out. The use of cell membrane-bound HLA class I molecules circumvents the need for laborious biochemical purification of these molecules in soluble form. Previously, we have applied this principle for HLA-A2 and HLA-A3. We now describe the assays for HLA-A1, HLA-A11, HLA-A24, HLA-A68, HLA-B7, HLA-B8, HLA-B14, HLA-B35, HLA-B60, HLA-B61, and HLA-B62. Together with HLA-A2 and HLA-A3, these alleles cover more than 95% of the Caucasian population. Several allele-specific parameters were determined for each assay. Using these assays, we identified novel HLA class I high-affinity binding peptides from HIVpol, p53, PRAME, and minor histocompatibility antigen HA-1. Thus these convenient and accurate peptide-binding assays will be useful for the identification of putative cytotoxic T lymphocyte epitopes presented on a diverse array of HLA class I molecules.

  15. EFFICIENT TRANSACTION REDUCTION IN ACTIONABLE PATTERN MINING FOR HIGH VOLUMINOUS DATASETS BASED ON BITMAP AND CLASS LABELS

    Directory of Open Access Journals (Sweden)

    K. Kavitha

    2013-07-01

    Full Text Available Frequent pattern mining in databases plays an indispensable role in many data mining tasks namely, classification, clustering, and association rules analysis. When a large number of item sets are processed by the database, it needs to be scanned multiple times. Consecutively, multiple scanning of the database increases the numberof rules generation, which then consume more system resources. Existing CCARM (Combined and Composite Association Rule Mining algorithm used minimum support in order to generate combined actionable association rules, which in turn suffer from the large number of generating rules. Explosion of a large number of rules is the major problem in frequent pattern mining that adds difficult to find the interesting frequent patterns. This paper presents anefficient transaction reduction technique named TR-BC to mine the frequent pattern based on bitmap and class labels. The proposed approach reduces the rule generation by counting the item support and class support instead of only item support. Moreover, the database storage is compressed by using bitmap that significantly reduces the number of database scan. The rules are reduced by horizontal and vertical transaction and then finally combined rules are generated by eliminating the redundancy. Experimental results validate the performance of the proposed approach and expose that proposed method is more effective and efficient than previously proposed algorithm.

    2001-01-01

    The objective of this study was to evaluate the effects of consumer involvement on information processing from over-the-counter (OTC) medication labels. A sample of 256 students evaluated simulated OTC product labels for two product categories (headache and cold) in random order. Each participant evaluated labels after reading a scenario to simulate high and low involvement respectively. A questionnaire was used to collect data on variables such as label comprehension, attitude-towards-product label, product evaluation, and purchase intention. The results indicate that when consumers are involved in their purchase of OTC medications they are significantly more likely to understand information from the label and evaluate it accordingly. However, involvement does not affect attitude-towards-product label nor does it enhance purchase intention. PMID:11727293

  20. OTC Derivatives: Impacts of Regulatory Changes in the Non-Financial Sector

    OpenAIRE

    Gustavo Silva Araujo; Sérgio Leão

    2015-01-01

    In the aftermath of the 2007-2008 global financial crisis, a series of measures has been proposed to regulate the OTC derivatives market. The motivation is to increase the disclosure of the OTC operations aiming to decrease the probability of crisis. The main objective of this paper is to investigate how regulatory changes in the OTC derivatives market affect the non-financial sector. The Brazilian FX derivatives market provides a natural experiment for the issue: in 2011 the Brazilian govern...

  1. The Network of Counterparty Risk: Analysing Correlations in OTC Derivatives.

    Counterparty risk denotes the risk that a party defaults in a bilateral contract. This risk not only depends on the two parties involved, but also on the risk from various other contracts each of these parties holds. In rather informal markets, such as the OTC (over-the-counter) derivative market, institutions only report their aggregated quarterly risk exposure, but no details about their counterparties. Hence, little is known about the diversification of counterparty risk. In this paper, we reconstruct the weighted and time-dependent network of counterparty risk in the OTC derivatives market of the United States between 1998 and 2012. To proxy unknown bilateral exposures, we first study the co-occurrence patterns of institutions based on their quarterly activity and ranking in the official report. The network obtained this way is further analysed by a weighted k-core decomposition, to reveal a core-periphery structure. This allows us to compare the activity-based ranking with a topology-based ranking, to identify the most important institutions and their mutual dependencies. We also analyse correlations in these activities, to show strong similarities in the behavior of the core institutions. Our analysis clearly demonstrates the clustering of counterparty risk in a small set of about a dozen US banks. This not only increases the default risk of the central institutions, but also the default risk of peripheral institutions which have contracts with the central ones. Hence, all institutions indirectly have to bear (part of) the counterparty risk of all others, which needs to be better reflected in the price of OTC derivatives. PMID:26335223

    2010-01-01

    Dwarf mistletoes, genus Arceuthobium, are parasitic flowering plants and forest pests. In western North America, Arceuthobium americanum (lodgepole pine dwarf mistletoe) is principally found on Pinus contorta var. latifolia (lodgepole pine). Dwarf mistletoes disperse their seeds by an explosive process that involves the buildup of hydrostatic pressure within a mucilaginous fruit tissue called the 'viscin'. Living viscin tissue envelops the discharged seeds. This study examined the possibility that aquaporins, critical in plant water relations, might be found in the dwarf mistletoe fruit, specifically the viscin cells. An antibody raised against a tobacco plasma membrane intrinsic 2 (PIP2) aquaporin was used with a gold-labeled secondary antibody to probe dwarf mistletoe fruit at various developmental stages. Viscin cell plasma membranes were successfully labeled with the anti-tobacco probe, and the validity of the immunolabeling was supported by Western blot analysis, showing a strong signal at about 30 kDa, which is at the expected size of a PIP2. A definitive immunolabeling pattern, supported by quantification of gold signal per membrane length, was observed: viscin cells sampled early in development had abundant gold label at their plasma membranes (1.93 +/- 0.13 to 2.13 +/- 0.33 gold particles per microm membrane), while other areas of the cells had no discernible label. Viscin cells sampled near the time of explosive discharge had significantly less label at the plasma membrane (0.21 gold particles +/- 0.11 per microm membrane, P < 0.05), and label was seen at vesicular membranes. Aquaporins likely have a role in directing water to the viscin mucilage early in development, but are retrieved via endocytosis to prevent excess water loss from viscin cells when discharge is imminent.

    2004-03-01

    Full Text Available Abstract Background Surveillance of Over-the-Counter pharmaceutical (OTC sales as a potential early indicator of developing public health conditions, in particular in cases of interest to Bioterrorism, has been suggested in the literature. The data streams of interest are quite non-stationary and we address this problem from the viewpoint of linear adaptive filter theory: the clinical data is the primary channel which is to be estimated from the OTC data that form the reference channels. Method The OTC data are grouped into a few categories and we estimate the clinical data using each individual category, as well as using a multichannel filter that encompasses all the OTC categories. The estimation (in the least mean square sense is performed using an FIR (Finite Impulse Response filter and the normalized LMS algorithm. Results We show all estimation results and present a table of effectiveness of each OTC category, as well as the effectiveness of the combined filtering operation. Individual group results clearly show the effectiveness of each particular group in estimating the clinical hospital data and serve as a guide as to which groups have sustained correlations with the clinical data. Conclusion Our results indicate that Multichannle adaptive FIR least squares filtering is a viable means of estimating public health conditions from OTC sales, and provide quantitative measures of time dependent correlations between the clinical data and the OTC data channels.

    2012-02-01

    Most of the success of electronic devices fabricated to actively interact with a biological environment relies on the proper choice of materials and efficient engineering of surfaces and interfaces. Organic materials have proved to be among the best candidates for this aim owing to many properties, such as the synthesis tunability, processing, softness and self-assembling ability, which allow them to form surfaces that are compatible with biological tissues. This review reports some research results obtained in the development of devices which exploit organic materials' properties in order to detect biologically significant molecules as well as to trigger/capture signals from the biological environment. Among the many investigated sensing devices, organic field-effect transistors (OFETs), organic electrochemical transistors (OECTs) and microcantilevers (MCLs) have been chosen. The main factors motivating this choice are their label-free detection approach, which is particularly important when addressing complex biological processes, as well as the possibility to integrate them in an electronic circuit. Particular attention is paid to the design and realization of biocompatible surfaces which can be employed in the recognition of pertinent molecules as well as to the research of new materials, both natural and inspired by nature, as a first approach to environmentally friendly electronics.

    2016-08-01

    Water spinach (Ipomoea aquatic Forsk.) was selected to investigate the effects of oxytetracycline (OTC) on the toxicity of soil contaminated by long-term sewage irrigation. After acute toxicity test in petri dish at nine different OTC-spiked levels for 48 h, the germination rate was found to be generally inhibited in all treatments treated with OTC but the root elongation and activities of several antioxidant enzymes, superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were either forward or backward stimulated to varying extent. During a 60-day sub-chronic toxicity test by means of a pot experiment, activities of SOD, POD and CAT in both the leaf and root tissue at 25 mg OTC per kg soil (dry weight) and in root tissue at 1 mg OTC per kg soil (dry weight) were significantly different than those in other treatments, which also indicated the higher sensitivity of the root. The foliar photosynthetic rate, stomatal conductance and transpiration rate were all gradually inhibited in spite of elevated water use efficiency under the pressure of the different OTC concentrations, which were highly significant different at 10 mg OTC per kg soil (dry weight). Indices of soil microbial diversity at 4 mg OTC kg(-1) soil were significantly different from those of the control, indicating the potential adverse effects of OTC to soil microorganisms. The results suggest that the introduction of OTC could damage both plants and soil microorganisms, and during sub-chronic incubation, the sensitivity of different indices generally followed the order of root tissue antioxidant enzyme activities, soil microbial diversity indices, leaf photosynthesis-related index and leaf tissue enzyme antioxidant activities. In addition, the application of livestock and poultry manure containing pollutants like OTC in farmland soil, especially if the soil has been contaminated before, should be taken more seriously in the context of the current pursuit of increased agricultural

    2015-01-01

    Effects of global changes on biodiversity have been paid more and more attention world widely, and the open top chambers (OTCs) are the most common tools to study the effects of climatic warming on plant diversity. However, it remains unclear how flowers evolve under environmental changes, which could help us to understand the changes of plant diversity in the OTCs. We compared the insect diversity and pollen:ovule (P/O) ratio of eight outcrossing species with different life histories inside and outside the OTCs on the Qinghai-Tibet Plateau, to examine the effects induced by OTCs on the evolution of floral traits. In the OTCs, P/O ratio decreased in annuals, but increased in perennials, indicating an overall trend toward selfing in annuals. We found that the insect diversity differed significantly inside and outside the OTCS, with decreases of dipteran insects and bees. We concluded that changes of P/O ratio in the studied plant species might result from pollination failure, which might be the results of mismatch between flowering time and pollinator activities. We also suggested annuals might be in a more extinction risk than perennials in OTCs, if strong inbreeding depression occurs in these annual outcrossing plants. PMID:25998558

    Directory of Open Access Journals (Sweden)

    Johan Lindh

    Full Text Available The head louse, Pediculus humanus capitis, is an obligate ectoparasite that causes infestations of humans. Studies have demonstrated a correlation between sales figures for over-the-counter (OTC treatment products and the number of humans with head lice. The deregulation of the Swedish pharmacy market on July 1, 2009, decreased the possibility to obtain complete sale figures and thereby the possibility to obtain yearly trends of head lice infestations. In the presented study we wanted to investigate whether web queries on head lice can be used as substitute for OTC sales figures. Via Google Insights for Search and Vårdguiden medical web site, the number of queries on "huvudlöss" (head lice and "hårlöss" (lice in hair were obtained. The analysis showed that both the Vårdguiden series and the Google series were statistically significant (p<0.001 when added separately, but if the Google series were already included in the model, the Vårdguiden series were not statistically significant (p = 0.5689. In conclusion, web queries can detect if there is an increase or decrease of head lice infested humans in Sweden over a period of years, and be as reliable a proxy as the OTC-sales figures.

  10. Towards Multi Label Text Classification through Label Propagation

    Directory of Open Access Journals (Sweden)

    Shweta C. Dharmadhikari

    2012-06-01

    Full Text Available Classifying text data has been an active area of research for a long time. Text document is multifaceted object and often inherently ambiguous by nature. Multi-label learning deals with such ambiguous object. Classification of such ambiguous text objects often makes task of classifier difficult while assigning relevant classes to input document. Traditional single label and multi class text classification paradigms cannot efficiently classify such multifaceted text corpus. Through our paper we are proposing a novel label propagation approach based on semi supervised learning for Multi Label Text Classification. Our proposed approach models the relationship between class labels and also effectively represents input text documents. We are using semi supervised learning technique for effective utilization of labeled and unlabeled data for classification. Our proposed approach promises better classification accuracy and handling of complexity and elaborated on the basis of standard datasets such as Enron, Slashdot and Bibtex.

    2015-12-01

    Full Text Available Background: In order to provide appropriate advice to the patient at the time of dispensing and over-the-counter (OTC medication counseling, community pharmacists need access to current and reliable information about medicines. Brazilian pharmacists have assumed new functions such as prescribing medication, in a dependent model, based in protocols. Objective: To examine the practice of community pharmacists in a Brazilian State, focusing on OTC recommendation. Method: A cross-sectional survey of community pharmacists in a state of Brazil was conducted from October 2013 to January 2014, with data collection through a pre-piloted self-administered anonymous survey via Survey Monkey® platform. Following ethical approval, the online instrument was sent to 8,885 pharmacists registered in Parana State, Brazil, focusing on professionals working in community pharmacies. The questionnaire assessed the community pharmacy setting, the search for information, the knowledge of the evidence-based practice, the important factors to consider when recommending an OTC medicine, and the pharmacist prescribing. Responses were imported into SPSS® (version 22.0 for analysis. Nonparametric tests were used to assess the association between responses and demographic information with a significance level less than 5% (p<0.05. Results: Of the pharmacists, 97.4% dispensed medications and counseled patients for a median of six hours per day. Product's efficacy (97% and adverse effects (62.3% were the most important factors taken into account when counseling a nonprescription medicine. Few pharmacists knew the meaning of terms related to evidence-based health. Most respondents agreed that pharmacists have the necessary training to prescribe. Conclusion: Over-the-counter medication counseling is a daily practice among Brazilian pharmacists. Learning needs exist for community pharmacists in relation to evidence-based practice. Thus, sources of information with good evidence

  16. Potentiometric studies on the complexes of tetracycline (TC) and oxytetracycline (OTC) with some metal ions

    International Nuclear Information System (INIS)

    The interaction of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Zn(II), Cd(II), Hg(II), Pb(II), Al(III), and UO2(II) ions with tetracycline (TC) were studied by potentiometric pH titrations. The formation constants of the different binary complexes formed in such systems have been determined at 25±0.1 deg C and μ=0.1 moll-1 (NaNO3). Potentiometric pH equilibrium measurements have been made under the same conditions for the interaction of oxytetracycline (OTC) and Cu(II), Cd(II), Pb(II), and UO2(II). The formation of (1:1) binary complexes are inferred from the potentiometric pH titration curves. The protonation constants of TC and OTC were also determined under the same conditions and refined (ESAB2M computer program). The transition metal stability constants are consistent with the Irving-Williams series. (authors)

  17. Effectiveness and legitimacy of forest carbon standards in the OTC voluntary carbon market

    Directory of Open Access Journals (Sweden)

    Merger Eduard

    2011-08-01

    Full Text Available Abstract Background In recent years, the voluntary over-the-counter (OTC carbon market has reached a significant market volume. It is particularly interesting for forest mitigation projects which are either ineligible in compliance markets or confronted with a plethora of technical and financial hurdles and lacking market demand. As the OTC market is not regulated, voluntary standards have been created to secure the social and environmental integrity of the traded mitigation projects and thus to ensure the quality of the resulting carbon credits. Building on a theoretical efficiency-legitimacy framework, this study aims to identify and analyse the characteristics and indicators that determine the efficiency and organisational legitimacy of standards for afforestation/reforestation carbon projects. Results All interviewed market actors consider third-party certification and standards as a crucial component of market functionality, which provide quality assurance mechanisms that reduce information asymmetries and moral hazard between the actors regarding the quality of carbon credits, and thus reduce transaction costs. Despite this development, the recent evolution of many new and differing standards is seen as a major obstacle that renders it difficult for project developers and buyers to select an appropriate standard. According to the interviewed experts the most important legitimating factors of standards are assurance of a sufficient level of quality of carbon credits, scientifically substantiated methodological accounting and independent third-party verification, independence of standard bodies, transparency, wide market acceptance, back-up of the wider community including experts and NGOs, rigorous procedures, and the resemblance to the Afforestation/Reforestation (A/R CDM due to its international policy endorsements. In addition, standards must provide evidence that projects contribute to a positive social and environmental development, do

    The role of labeling is to solve the adverse selection problem caused by unsubstantiated claims from firms. The problem however is likely to remain unsolved if the labeling agency is not trustworthy.The agency can be suspected to divert the fees charged for labeling from their primary purpose of collecting information in order to raise excessive revenue. This paper addresses this issue and shows that labeling may be wasteful if the agency is likely to be untrustworthy. To award firms green la...

    1. The paper describes the mental disturbances of 44 abusive cases of "BRON," an over-the-counter (OTC) cough suppressant solution containing methylephedrine, codeine, caffeine, and chlorpheniramine. 2. Major psychiatric symptoms observed included hallucinatory-paranoid state and affective disorder. There also were groups which exhibited a combination of the two states and abuse only. 3. The hallucinatory-paranoid state group had a relatively small BRON usage amount, short usage term and few withdrawal symptoms. The affective disorder group, in contrast, had large usage amount, longer usage term, and showed significant autonomic nerve disorders during withdrawal. These tendencies were seen more clearly in the mixed state group. 4. The hallucinatory-paranoid state group showed little or no physical dependence, while that of the affective disorder group was thought to be firmly established. Thus, in the former group, methylephedrine was considered the major behavior modifying drug, while in the latter, it was thought to be codeine. PMID:1749828

    Full Text Available Aim: The study was conducted to evaluate use of over the counter (OTC drugs among the medical students, nursing and clerical staff of tertiary care teaching rural hospital to determine the awareness and disadvantages on use of OTC. Methods: Responses to a feedback questionnaire covering various aspects on usage of OTC drugs were obtained from 100 medical students, 100 nursing and 100 clerical staff. Results: Among 300 respondents, 84% used OTC, commonly purchased by self. Majority of them started self medication within 2 days of their illness. The frequently reported illness that prompted self-medication included headache, cough and cold, fever, generalised weakness, acidity, dysmenorrhoea, and sleep disturbances. Majority of them obtained OTC by mentioning name of drug (81%, 35% by telling symptom and 15% by showing old prescription. We found that 87% people share OTC among relatives and friends. Conclusions: Usage of OTC was highest amongst medical students and nursing staff. Time consumption for consultation, the consultation fees and frequent visits were the commonly mentioned reasons for self medication. It was analysed that none of the clerical staff were aware of the drug, dose, frequency of administration and adverse reactions. While very little awareness of medication was found even among nursing staff and medical students. Therefore it is suggested that the public has to be educated on the type of illnesses to be self-diagnosed and medicated, dangers of OTC on misuse which would possibly lead to delay in detection of more serious underlying ailment and timely medication.

    Water and wastewater effluents contain a vast range of chemicals in mixtures that have different chemical structures and characteristics. This study presents a treatment technology for the removal of mixtures of antibiotic residues (sulfamethoxazole (SMX), oxtetracycline (OTC) and ciprofloxacin (CIP)) from contaminated water. The treatment combines pH modification of the water to an optimal value, followed by a photolytic treatment using direct polychromatic ultraviolet (UV) irradiation by medium pressure UV lamp. The pH adjustment of the treated water leads to structural modifications of the pollutant's molecule thus may enhance direct photolysis by UV light. Results showed that an increase of water pH from 5 to 7 leads to a decrease in degradation rate of SMX and an increase in degradation rate of OTC and CIP, when studied separately and not in a mixture. Thus, the optimal pH values for UV photodegradation in a mixture, involve initial photolysis at pH 5 and then gradually changing the pH from 5 to 7 during the UV exposure. For example, this resulted in 99% degradation of SMX at pH 5 and enhanced degradation of OTC and CIP from 54% and 26% to 91% and 96% respectively when pH was increased from 5 to 7. Thus the pH induced photolytic treatment has a potential in improving treatment of antibiotics in mixtures.

  9. Isotopically labelled benzodiazepines

    International Nuclear Information System (INIS)

    This paper reports on the benzodiazepines which are a class of therapeutic agents. Improvements in the analytical methodology in the areas of biochemistry and pharmacology were significant, particularly in the application of chromatographic and spectroscopic techniques. In addition, the discovery and subsequent development of tritium and carbon-14 as an analytical tool in the biological sciences were essentially post-world war II phenomena. Thus, as these new chemical entities were found to be biologically active, they could be prepared in labeled form for metabolic study, biological half-life determination (pharmacokinetics), tissue distribution study, etc. This use of tracer methodology has been liberally applied to the benzodiazepines and also more recently to the study of receptor-ligand interactions, in which tritium, carbon-11 or fluorine-18 isotopes have been used. The history of benzodiazepines as medicinal agents is indeed an interesting one; an integral part of that history is their use in just about every conceivable labeled form

  10. 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.

    We construct classes of superconformal theories elements of which are labeled by punctured Riemann surfaces. Degenerations of the surfaces correspond, in some cases, to weak coupling limits. Different classes are labeled by two integers ( N, k). The k = 1 case coincides with A N - 1 theories of class and simple examples of theories with k > 1 are orbifolds of some of the A N - 1 class theories. For the space of theories to be complete in an appropriate sense we find it necessary to conjecture existence of new strongly coupled SCFTs. These SCFTs when coupled to additional matter can be related by dualities to gauge theories. We discuss in detail the A 1 case with k = 2 using the supersymmetric index as our analysis tool. The index of theories in classes with k > 1 can be constructed using eigenfunctions of elliptic quantum mechanical models generalizing the Ruijsenaars-Schneider integrable model. When the elliptic curve of the model degenerates these eigenfunctions become polynomials with coefficients being algebraic expressions in fugacities, generalizing the Macdonald polynomials with rational coefficients appearing when k = 1.

  15. Modeling, analysis and comparison of TSR and OTC methods for MPPT and power smoothing in permanent magnet synchronous generator-based wind turbines

    International Nuclear Information System (INIS)

    Highlights: • Small signal modeling of PMSG wind turbine with two controllers are introduced. • Poles and zeroes analyzing of OTC and TSR methods is performed. • Generator output power with varying wind speed in PMSG wind turbine is studied. • MPPT capability of OTC and TSR methods to wind speed variations are compared. • Power smoothing capability and reducing mechanical stress of both methods are studied. - Abstract: This paper presents a small signal modeling of a direct-driven permanent magnet synchronous generator (PMSG) based on wind turbine which is connected to the grid via back-to-back converters. The proposed small signal model includes two maximum power point tracking (MPPT) controllers: tip speed ratio (TSR) control and optimal torque control (OTC). These methods are analytically compared to illustrate MPPT and power smoothing capability. Then, to compare the MPPT and power smoothing operation of the mentioned methods, simulations are performed in MATLAB/Simulink software. From the simulation results, OTC is highly efficient in power smoothing enhancement and has clearly good performance to extract maximum power from wind; however, TSR control has definitely fast responses to wind speed variations with the expense of higher fluctuations due to its non-minimum phase characteristic

    We present a unified general method for the asymptotic study of graphs from the so-called "subcritical"$ $ graph classes, which include the classes of cacti graphs, outerplanar graphs, and series-parallel graphs. This general method works both in the labelled and unlabelled framework. The main results concern the asymptotic enumeration and the limit laws of properties of random graphs chosen from subcritical classes. We show that the number $g_n/n!$ (resp. $g_n$) of labelled (resp. unlabelled) graphs on $n$ vertices from a subcritical graph class ${\\cG}=\\cup_n {\\cG_n}$ satisfies asymptotically the universal behaviour

    2015-05-01

    Full Text Available Most of the text classification problems are associated with multiple class labels and hence automatic text classification is one of the most challenging and prominent research area. Text classification is the problem of categorizing text documents into different classes. In the multi-label classification scenario, each document is associated may have more than one label. The real challenge in the multi-label classification is the labelling of large number of text documents with a subset of class categories. The feature extraction and classification of such text documents require an efficient machine learning algorithm which performs automatic text classification. This paper describes the multi-label classification of product review documents using Structured Support Vector Machine.

  1. Method for automatic determination of soybean actual evapotranspiration under open top chambers (OTC) subjected to effects of water stress and air ozone concentration.

    2012-10-01

    The present study describes an operational method, based on the Katerji et al. (Eur J Agron 33:218-230, 2010) model, for determining the daily evapotranspiration (ET) for soybean inside open top chambers (OTCs). It includes two functions, calculated day par day, making it possible to separately take into account the effects of concentrations of air ozone and plant water stress. This last function was calibrated in function of the daily values of actual water reserve in the soil. The input variables of the method are (a) the diurnal values of global radiation and temperature, usually measured routinely in a standard weather station; (b) the daily values of the AOT40 index accumulated (accumulated ozone over a threshold of 40 ppb during daylight hours, when global radiation exceeds 50 Wm(-2)) determined inside the OTC; and (c) the actual water reserve in the soil, at the beginning of the trial. The ensemble of these input variables can be automatable; thus, the proposed method could be applied in routine. The ability of the method to take into account contrasting conditions of ozone air concentration and water stress was evaluated over three successive years, for 513 days, in ten crop growth cycles, excluding the days employed to calibrate the method. Tests were carried out in several chambers for each year and take into account the intra- and inter-year variability of ET measured inside the OTCs. On the daily scale, the slope of the linear regression between the ET measured by the soil water balance and that calculated by the proposed method, under different water conditions, are 0.98 and 1.05 for the filtered and unfiltered (or enriched) OTCs with root mean square error (RMSE) equal to 0.77 and 1.07 mm, respectively. On the seasonal scale, the mean difference between measured and calculated ET is equal to +5% and +11% for the filtered and unfiltered OTCs, respectively. The ability of the proposed method to estimate the daily and seasonal ET inside the OTCs is

  3. Simultaneous segmentation and statistical label fusion

    Asman, Andrew J.; Landman, Bennett A.

    2012-02-01

    Labeling or segmentation of structures of interest in medical imaging plays an essential role in both clinical and scientific understanding. Two of the common techniques to obtain these labels are through either fully automated segmentation or through multi-atlas based segmentation and label fusion. Fully automated techniques often result in highly accurate segmentations but lack the robustness to be viable in many cases. On the other hand, label fusion techniques are often extremely robust, but lack the accuracy of automated algorithms for specific classes of problems. Herein, we propose to perform simultaneous automated segmentation and statistical label fusion through the reformulation of a generative model to include a linkage structure that explicitly estimates the complex global relationships between labels and intensities. These relationships are inferred from the atlas labels and intensities and applied to the target using a non-parametric approach. The novelty of this approach lies in the combination of previously exclusive techniques and attempts to combine the accuracy benefits of automated segmentation with the robustness of a multi-atlas based approach. The accuracy benefits of this simultaneous approach are assessed using a multi-label multi-atlas whole-brain segmentation experiment and the segmentation of the highly variable thyroid on computed tomography images. The results demonstrate that this technique has major benefits for certain types of problems and has the potential to provide a paradigm shift in which the lines between statistical label fusion and automated segmentation are dramatically blurred.

  18. Interval prediction for graded multi-label classification

    CERN Document Server

    Lastra, Gerardo; Bahamonde, Antonio

    2014-01-01

    Multi-label was introduced as an extension of multi-class classification. The aim is to predict a set of classes (called labels in this context) instead of a single one, namely the set of relevant labels. If membership to the set of relevant labels is defined to a certain degree, the learning task is called graded multi-label classification. These learning tasks can be seen as a set of ordinal classifications. Hence, recommender systems can be considered as multi-label classification tasks. In this paper, we present a new type of nondeterministic learner that, for each instance, tries to predict at the same time the true grade for each label. When the classification is uncertain for a label, however, the hypotheses predict a set of consecutive grades, i.e., an interval. The goal is to keep the set of predicted grades as small as possible; while still containing the true grade. We shall see that these classifiers take advantage of the interrelations of labels. The result is that, with quite narrow intervals, i...

  19. Deuterium labeled cannabinoids

    International Nuclear Information System (INIS)

    Complex reactions involving ring opening, ring closure and rearrangements hamper complete understanding of the fragmentation processes in the mass spectrometric fragmentation patterns of cannabinoids. Specifically labelled compounds are very powerful tools for obtaining more insight into fragmentation mechanisms and ion structures and therefore the synthesis of specifically deuterated cannabinoids was undertaken. For this, it was necessary to investigate the preparation of cannabinoids, appropriately functionalized for specific introduction of deuterium atom labels. The results of mass spectrometry with these labelled cannabinoids are described. (Auth.)

  3. Class distinction

    Science.gov (United States)

    White, M. Catherine

    Typical 101 courses discourage many students from pursuing higher level science and math courses. Introductory classes in science and math serve largely as a filter, screening out all but the most promising students, and leaving the majority of college graduates—including most prospective teachers—with little understanding of how science works, according to a study conducted for the National Science Foundation. Because few teachers, particularly at the elementary level, experience any collegiate science teaching that stresses skills of inquiry and investigation, they simply never learn to use those methods in their teaching, the report states.

  6. 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.

  10. Label Fusion Strategy Selection

    Directory of Open Access Journals (Sweden)

    Nicolas Robitaille

    2012-01-01

    Full Text Available Label fusion is used in medical image segmentation to combine several different labels of the same entity into a single discrete label, potentially more accurate, with respect to the exact, sought segmentation, than the best input element. Using simulated data, we compared three existing label fusion techniques—STAPLE, Voting, and Shape-Based Averaging (SBA—and observed that none could be considered superior depending on the dissimilarity between the input elements. We thus developed an empirical, hybrid technique called SVS, which selects the most appropriate technique to apply based on this dissimilarity. We evaluated the label fusion strategies on two- and three-dimensional simulated data and showed that SVS is superior to any of the three existing methods examined. On real data, we used SVS to perform fusions of 10 segmentations of the hippocampus and amygdala in 78 subjects from the ICBM dataset. SVS selected SBA in almost all cases, which was the most appropriate method overall.

    2016-02-01

    Mislabeled surgical specimens jeopardize patient safety and quality care. The purpose of this project was to determine whether labeling surgical specimens with two patient identifiers would result in an 80% reduction in specimen labeling errors within six months and a 100% reduction in errors within 12 months. Our failure mode effects analysis found that the lack of two patient identifiers per label was the most unsafe step in our specimen handling process. We piloted and implemented a new process in the OR using the Plan-Do-Check-Act conceptual framework. The audit process included collecting data and making direct observations to determine the sustainability of the process change; however, the leadership team halted the direct observation audit after four months. The total number of surgical specimen labeling errors was reduced by only 60% within six months and 62% within 12 months; therefore, the goal of the project was not met. However, OR specimen labeling errors were reduced. PMID:26849982

  17. What's driving energy efficient appliance label awareness and purchase propensity?

    International Nuclear Information System (INIS)

    The EU appliance energy consumption labeling scheme is a key component of efforts to increase the diffusion of energy-efficient household appliances. In this paper, the determinants of consumer knowledge of the energy label for household appliances and the choice of class-A energy-efficient appliances are jointly estimated using data from a large survey of more than 20,000 German households. The results for five major appliances suggest that lack of knowledge of the energy label can generate considerable bias in both estimates of rates of uptake of class-A appliances and in estimates of the underlying determinants of choice of class-A appliance. Simulations of the choice to purchase a class-A appliance, given knowledge of the labeling framework, reveal that residence characteristics and, in several cases, regional electricity prices strongly increase the propensity to purchase a class-A appliance, but socio-economic characteristics have surprisingly little impact on appliance energy-class choice.

    The descriptive “conventions” used on food labels are always evolving. Today, however, the changes are so complicated (partly driven by legislation requiring disclosures about environmental impacts, health issues, and geographical provenance) that these labels more often baffle buyers than enlighten them. In a light-handed manner, the article points to how sometimes reading label language can be like deciphering runes—and how if we are familiar with the technical terms, we can find a literal meaning, but still not see the implications. The article could be ten times longer because food labels vary according to cultures—but all food-exporting cultures now take advantage of our short attention-span when faced with these texts. The question is whether less is more—and if so, in this contest for our attention, what “contestant” is voted off. PMID:21539053

    International Nuclear Information System (INIS)

    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

    Full Text Available Introduction & Objective: Pharmacists usually encounter requests for over the counter drugs. How a pharmacist performs in evaluating patients' signs and symptoms, treating them, and moreover his or her approach in prescribing over the counter (OTC medications were the main goals of this study. Materials & Methods: In this cross- sectional study, the scenarios of cough, diarrhea and com-mon cold were obtained from questionnaires. These scenarios were then designed by deter-mining key questions. From the overall pharmacies in Hamadan, for each of the three scenar-ios, 46 pharmacies were randomly selected and analyzed. Performance of pharmacists, includ-ing their interventions on over the counter counseling, asking key questions, explaining drugs' side effects and interactions, and their approach of prescribing medications, were measured. Moreover, the influence of pharmacists' gender and type of the pharmacy were determined. Results: In 41 out of 179 visits, pharmacists were not present in the pharmacy (22.9%, mostly in suburban pharmacies. The pharmacists' performances in explaining drug interactions were significantly better in urban pharmacies in comparison with suburban ones. Moreover, subur-ban pharmacies and male pharmacists, in comparison with urban pharmacies and female pharmacists, prescribed more drugs. Conclusion: This study shows that despite the pharmacists asking the key questions ,the major-ity of pharmacists made weak recommendations. In order to improve pharmacists perform-ances, modification of educational system for pharmacy students in addition to the continu-ous and effective supervision of authorities on pharmacists' performance in OTC drugs is suggested.

  12. Radioactive labelling of peptidic hormones

    International Nuclear Information System (INIS)

    The labelling of peptidic hormones requires stability, specificity and sensitivity of the label. Introduction of a radioactive atome is one way to satisfy these criteria. Several processes have been described to prepare radioactive TRF: synthesis of the peptide with labelled aminoacids or introduction of the label into the hormone. In that approach, tritium can be substituted in the imidazole ring, via precursors activating the proper carbon. Monoiodo TRF leads essentially to tritium labelling of the 5 positions whereas monoazo TRF allows the preparation of 3H TRF labelled in the 2 positions. Di-substituted TRF leads to labelling into the 2 and 5 carbons. Labelled analogs of TRF can be prepared with labelled iodine; further developments of peptide labelling, will be presented. In particular, the homolytic scission of the C-iodine, bond by photochemical activation. The nascent carbon radical can be stabilized by a tritiated scavenger. This approach eliminates the use of heavy metal catalysts

  13. Labeled Graph Kernel for Behavior Analysis.

    Science.gov (United States)

    Zhao, Ruiqi; Martinez, Aleix M

    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. PMID:26415154

A new method for synthesizing 15N-labeled 4-ethylsulfonyl-1-naphthalene-sulfonamide was developed. Studies were conducted on pathways to oleic-1-13C acid and a second pathway investigated was based on carbonation of 8-heptadecynylmagnesium bromide with CO2 to prepare sterolic acid. Biosynthetic preparations included glucose-13C from starch isolated from tobacco leaves following photosynthetic incubation with 13CO2 and galactose-13C from galactosylglycerol-13C from kelp. Research on growth of organisms emphasized photosynthetic growth of algae in which all cellular carbon is labeled. Preliminary experiments were performed to optimize the growth of Escherichia coli on sodium acetate-13C

    The work presented in this thesis deals with the problems involved in the adaption of reactor-produced fluorine-18 to the synthesis of 18F-labelled organic fluorine compounds. Several 18F-labelling reagents were prepared and successfully applied. The limitations to the synthetic possibilities of reactor-produced fluoride-18 become manifest in the last part of the thesis. An application to the synthesis of labelled aliphatic fluoro amino acids has appeared to be unsuccessful as yet, although some other synthetic approaches can be indicated. Seven journal articles (for which see the availability note) are used to compose the four chapters and three appendices. The connecting text gives a survey of known 18F-compounds and methods for preparing such compounds. (Auth.)

  19. Radioactively labelled porphyrin derivatives

    International Nuclear Information System (INIS)

    Radioactive labelling of guanidine bearing tetraphenylporphyrin and Dy-texaphyrin with 166Ho and 90Y is described. UV-VIS absorption spectrometry was used to describe porphyrin and texaphyrin, including their behaviour over a wide pH range. This technique also provided preliminary information about the complexation of holmium and yttrium with porphyrin and texaphyrin. The labelling yield of the macrocyclic molecules depends on the pH of the reaction mixture, metal-to-ligand ratio and time of incubation. The optimum reaction conditions for the formation of radioactive complexes of porphyrin and texaphyrin were determined by thin layer chromatography combined with beta activity measurement. The ability of porphyrin derivatives to bind anions was also examined. Our experiments were focused on perrhenate ion (ReO4-) because radiopharmaceuticals labeled with 186Re and 188Re play an important role in the therapy of many tumorous diseases. The possibility of using the ReO4- anion directly for labeling without reduction to a lower oxidation state can simplify considerably the preparation of the radiotherapeutic pharmaceuticals.

    Map labeling is the cartographic problem of placing the names of features (for example cities or rivers) on the map. A good labeling has no intersections between labels. Even basic versions of the problem are NP-hard. In addition, realistic map-labeling problems deal with many cartographic constraints, which pose more demands on how the labels should be placed in relation to their surroundings. For example, a label is preferably placed above and to the right of a city. These two aspects (comb...

But, it has not been investigated whether the distance-weighted strategy is valid for multi-label learning and which weightin...

    Inexpensive RGB-D cameras that give an RGB image together with depth data have become widely available. We use this data to build 3D point clouds of a full scene. In this paper, we address the task of labeling objects in this 3D point cloud of a complete indoor scene such as an office. We propose a graphical model that captures various features and contextual relations, including the local visual appearance and shape cues, object co-occurrence relationships and geometric relationships. With a large number of object classes and relations, the model's parsimony becomes important and we address that by using multiple types of edge potentials. The model admits efficient approximate inference, and we train it using a maximum-margin learning approach. In our experiments over a total of 52 3D scenes of homes and offices (composed from about 550 views, having 2495 segments labeled with 27 object classes), we get a performance of 84.06% in labeling 17 object classes for offices, and 73.38% in labeling 17 object classe...

    International Nuclear Information System (INIS)

    This paper report on isotopically labelled compounds. The first indexing system for isotopically labelled organic compounds is generally credited to Boughton and named after him. An extension of his principles for designating compounds containing hydrogen isotopes has been part of the Chemical Abstracts Service index nomenclature system for many years. After close on five years labor the IUPAC sponsored Commission on Nomenclature of Organic Chemistry presented in 1979 their findings on Isotopically Modified Compounds. The system codified in their rules provides for recognition of various types of isotopic modification and is therefore of more general applicability. Concurrently the rules for the nomenclature of isotopically modified inorganic compounds are developed. These are to be seen as supplementing and extending the guidelines laid down in the IUPAC Inorganic Nomenclature Rules already published

  2. Label-Guided Graph Exploration with Adjustable Ratio of Labels

    CERN Document Server

    Zhang, Meng; Tang, Jijun

    2012-01-01

    The graph exploration problem is to visit all the nodes of a connected graph by a mobile entity, e.g., a robot. The robot has no a priori knowledge of the topology of the graph or of its size. Cohen et al. \\cite{Ilcinkas08} introduced label guided graph exploration which allows the system designer to add short labels to the graph nodes in a preprocessing stage; these labels can guide the robot in the exploration of the graph. In this paper, we address the problem of adjustable 1-bit label guided graph exploration. We focus on the labeling schemes that not only enable a robot to explore the graph but also allow the system designer to adjust the ratio of the number of different labels. This flexibility is necessary when maintaining different labels may have different costs or when the ratio is pre-specified. We present 1-bit labeling (two colors, namely black and white) schemes for this problem along with a labeling algorithm for generating the required labels. Given an $n$-node graph and a rational number $\\rh...

    Delong, Andrew; Gorelick, Lena; Schmidt, Frank R; Veksler, Olga; Boykov, Yuri

    2011-01-01

    In interactive segmentation, the most common way to model object appearance is by GMM or histogram, while MRFs are used to encourage spatial coherence among the object labels. This makes the strong assumption that pixels within each object are i.i.d. when in fact most objects have multiple distinct appearances and exhibit strong spatial correlation among their pixels. At the very least, this calls for an MRF-based appearance model within each object itself and yet, to the best of our knowledge, such a "two-level MRF" has never been proposed. We propose a novel segmentation energy that can model complex appearance. We represent the appearance of each object by a set of distinct spatially coherent models. This results in a two-level MRF with "super-labels" at the top level that are partitioned into "sub-labels" at the bottom. We introduce the hierarchical Potts (hPotts) prior to govern spatial coherence within each level. Finally, we introduce a novel algorithm with EM-style alternation of proposal, α-expansion and re-estimation steps. Our experiments demonstrate the conceptual and qualitative improvement that a two-level MRF can provide. We show applications in binary segmentation, multi-class segmentation, and interactive co-segmentation. Finally, our energy and algorithm have interesting interpretations in terms of semi-supervised learning. PMID:25309973

  4. Labelled compounds. (Pt. B)

    International Nuclear Information System (INIS)

    Since the end of World War II there has been a tremendous increase in the number of compounds that have been synthesized with radioactive or stable isotopes. They have found application in many diverse fields, so much so, that hardly a single area in pure and applied science has not benefited. Not surprisingly it has been reflected in appearance of related publications. The early proceedings of the Symposia on Advances in Trace Methodology were soon followed by various Euratom sponsored meetings in which methods of preparing and storing labelled compounds featured prominently. In due course a resurgence of interest in stable isotopes, brought about by their greater availability (also lower cost) and partly by development of new techniques such as gas chromatography - mass spectrometry (gc-ms), led to the publication of proceedings of several successful conferences. More recently conferences dealing with the synthesis and applications of isotopes and isotopically labelled compounds have been established on a regular basis. In addition to the proceedings of conferences and journal publications individuals left their mark by producing definitive texts, usually on specific nuclides. Only the classic two volume publication of Murray and Williams (Organic syntheses with isotopes, New York 1985), now over 30 years old and out of print, attempted to do justice to several nuclides. With the large amount of work that has been undertaken since then it seems unlikely that an updated edition could be produced. The alternative strategy was to ask scientists currently active to review specific areas and this is the approach adopted in the present series of monographs. In this way it is intended to cover the broad advances that have been made in the synthesis and applications of isotopes and isotopically labelled compounds in the physical and biomedical sciences.

However, class families which are...... expressed using virtual classes seem to be very tightly coupled internally.

    Full Text Available Protein microarray technology has gone through numerous innovative developments in recent decades. In this review, we focus on the development of protein detection methods embedded in the technology. Early microarrays utilized useful chromophores and versatile biochemical techniques dominated by high-throughput illumination. Recently, the realization of label-free techniques has been greatly advanced by the combination of knowledge in material sciences, computational design and nanofabrication. These rapidly advancing techniques aim to provide data without the intervention of label molecules. Here, we present a brief overview of this remarkable innovation from the perspectives of label and label-free techniques in transducing nano‑biological events.

    We introduce the concept of an edge-colouring total k-labelling. This is a labelling of the vertices and the edges of a graph G with labels 1, 2, ..., k such that the weights of the edges define a proper edge colouring of G. Here the weight of an edge is the sum of its label and the labels of its...... two endvertices. We define χ (G) to be the smallest integer k for which G has an edge-colouring total k-labelling. This parameter has natural upper and lower bounds in terms of the maximum degree Δ of G : ⌈ (Δ + 1) / 2 ⌉ ≤ χ (G) ≤ Δ + 1. We improve the upper bound by 1 for every graph and prove χ (G...

  15. Bayesian Joint Modelling for Object Localisation in Weakly Labelled Images.

    Science.gov (United States)

    Shi, Zhiyuan; Hospedales, Timothy M; Xiang, Tao

    2015-10-01

    We address the problem of localisation of objects as bounding boxes in images and videos with weak labels. This weakly supervised object localisation problem has been tackled in the past using discriminative models where each object class is localised independently from other classes. In this paper, a novel framework based on Bayesian joint topic modelling is proposed, which differs significantly from the existing ones in that: (1) All foreground object classes are modelled jointly in a single generative model that encodes multiple object co-existence so that "explaining away" inference can resolve ambiguity and lead to better learning and localisation. (2) Image backgrounds are shared across classes to better learn varying surroundings and "push out" objects of interest. (3) Our model can be learned with a mixture of weakly labelled and unlabelled data, allowing the large volume of unlabelled images on the Internet to be exploited for learning. Moreover, the Bayesian formulation enables the exploitation of various types of prior knowledge to compensate for the limited supervision offered by weakly labelled data, as well as Bayesian domain adaptation for transfer learning. Extensive experiments on the PASCAL VOC, ImageNet and YouTube-Object videos datasets demonstrate the effectiveness of our Bayesian joint model for weakly supervised object localisation.

  16. Using Label Noise Robust Logistic Regression for Automated Updating of Topographic Geospatial Databases

    Science.gov (United States)

    Maas, A.; Rottensteiner, F.; Heipke, C.

    2016-06-01

    Supervised classification of remotely sensed images is a classical method to update topographic geospatial databases. The task requires training data in the form of image data with known class labels, whose generation is time-consuming. To avoid this problem one can use the labels from the outdated database for training. As some of these labels may be wrong due to changes in land cover, one has to use training techniques that can cope with wrong class labels in the training data. In this paper we adapt a label noise tolerant training technique to the problem of database updating. No labelled data other than the existing database are necessary. The resulting label image and transition matrix between the labels can help to update the database and to detect changes between the two time epochs. Our experiments are based on different test areas, using real images with simulated existing databases. Our results show that this method can indeed detect changes that would remain undetected if label noise were not considered in training.

  19. Co-Labeling for Multi-View Weakly Labeled Learning.

    Science.gov (United States)

    Xu, Xinxing; Li, Wen; Xu, Dong; Tsang, Ivor W

    2016-06-01

    It is often expensive and time consuming to collect labeled training samples in many real-world applications. To reduce human effort on annotating training samples, many machine learning techniques (e.g., semi-supervised learning (SSL), multi-instance learning (MIL), etc.) have been studied to exploit weakly labeled training samples. Meanwhile, when the training data is represented with multiple types of features, many multi-view learning methods have shown that classifiers trained on different views can help each other to better utilize the unlabeled training samples for the SSL task. In this paper, we study a new learning problem called multi-view weakly labeled learning, in which we aim to develop a unified approach to learn robust classifiers by effectively utilizing different types of weakly labeled multi-view data from a broad range of tasks including SSL, MIL and relative outlier detection (ROD). We propose an effective approach called co-labeling to solve the multi-view weakly labeled learning problem. Specifically, we model the learning problem on each view as a weakly labeled learning problem, which aims to learn an optimal classifier from a set of pseudo-label vectors generated by using the classifiers trained from other views. Unlike traditional co-training approaches using a single pseudo-label vector for training each classifier, our co-labeling approach explores different strategies to utilize the predictions from different views, biases and iterations for generating the pseudo-label vectors, making our approach more robust for real-world applications. Moreover, to further improve the weakly labeled learning on each view, we also exploit the inherent group structure in the pseudo-label vectors generated from different strategies, which leads to a new multi-layer multiple kernel learning problem.

  20. Multi-dimensional classification with super-classes

    OpenAIRE

    Read, Jesse; Bielza Lozoya, Maria Concepcion; Larrañaga Múgica, Pedro

    2014-01-01

    The multi-dimensional classification problem is a generalisation of the recently-popularised task of multi-label classification, where each data instance is associated with multiple class variables. There has been relatively little research carried out specific to multi-dimensional classification and, although one of the core goals is similar (modelling dependencies among classes), there are important differences; namely a higher number of possible classifications. In this paper we present me...

  1. Labelled molecules, modern research implements

    International Nuclear Information System (INIS)

    Details of the synthesis of carbon 14- and tritium-labelled molecules are examined. Although the methods used are those of classical organic chemistry the preparation of carbon 14-labelled molecules differs in some respects, most noticeably in the use of 14CO2 which requires very special handling techniques. For the tritium labelling of organic molecules the methods are somewhat different, very often involving exchange reactions. The following are described in turn: the so-called Wilzbach exchange method; exchange by catalysis in solution; catalytic hydrogenation with tritium; reductions with borotritides. Some applications of labelled molecules in organic chemistry, biochemistry and pharmacology are listed

  2. The radioactive labeling of monocytes

    International Nuclear Information System (INIS)

    With the aim of studying a possible relationship between circulating monocytes and Sternberg-Reed cells investigations were started on the specific labeling of monocytes. In this thesis the literature on the pertinent data has been reviewed and a series of experiments on the monocyte labeling procedure has been described. The principles of cell labeling with radioactive compounds were discussed. 1. Total separation of the particular cell population to be labeled and subsequent labeling with a non-specific radiopharmaceutical. 2. Specific cell labeling in a mixture of cell types based on a well defined affinity of the cell under study for the radiopharmaceutical used. Next the radionuclides that can be used for cell labeling purposes were discussed with special attention for 111In and its chelates. The principles of radiodosimetry were also discussed shortly. This section was focussed on the radiation dose the labeled cells receive because of the intracellular localized radioactivity. The radiation burden is high in comparison to amounts of radiation known to affect cell viability. A newly developed method for labeling monocytes specifically by phagocytosis of 111In-Fe-colloid without apparent loss of cells was described in detail. (Auth.)

  6. Limitations of Label-Free Sensors in Serum Based Molecular Diagnostics

    CERN Document Server

    Varma, Manoj M

    2015-01-01

    Immunoassay formats applicable for clinical or point-of-care diagnostics fall into two broad classes. One which uses labeled secondary antibodies for signal transduction and the other which does not require the use of any labels. Comparison of the limits of detection (LoD) reported by these two sensing approaches over a wide range of detection techniques and target molecules in serum revealed that labeled techniques achieve 2-3 orders of magnitude better LoDs. Further, a vast majority of commercial tests and recent examples of technology translations are based on labeled assay formats. In light of this data, it is argued that extension of traditional labeled approaches and enhancing their functionality may have better clinical impact than the development of newer label-free techniques.

  7. Oxygen labelled CO2

    International Nuclear Information System (INIS)

    Tests were carried out as to whether additional information concerning pulmonary gas exchange could be obtained from the application of oxygen labelled carbon dioxide. Single breath experiments were performed on two healthy subjects with 0.1 percent C16O18O and 2.8 percent C18O2 in the inspiratory gas. Breath-hold time was varied between 0.5-20s in different experiments. The 18O-concentration of the end-expired gas bi-exponentially decreased with increasing breath-hold time. The high and low rate constants 4s-1 and 0.12s-1 for C18O2 and 2.5s-1 and 0.87s-1 for C16O18O were derived, respectively. These results, together with model calculations, suggest: 1) the rapid disappearance of C18O2 from the alveolar space is primarily limited by diffusion, so that this isotopic species can be applied to quantify pulmonary diffusing conditions; 2) the lower disappearance rate of C16O18O is caused by a lower equilibration kinetics in blood, so that this isotopic species offers a possibility to study carbonic anhydrase activity of the red cells in vivo; 3) the slow phase of label decay is influenced by both alveolar dead space and carbonic anhydrase activity of the pulmonary tissues. Pathological dead spaces are expected to be sensitively detectable by C16O18O as well as by C18O2. (author). 4 refs.; 4 figs

    2005-01-01

    On the basis of inner-system labeling signaling used in the integrated access system,a kind of inner-system labeling algorithm is introduced in this paper, and the fairness of the algorithm for each traffic stream in the integrated-services is analyzed. The base of this algorithm is Class of Services (CoS), and each packet entering the relative independent area (an autonomous system) would be labeled according to the service type or Quality of Service (QoS) in demand,and be scheduled and managed within the system (the system can be enlarged if conforming to the same protocol). The experimental results show that each of the stream rate in the integratedservices would converge to a stable value if the rates of transmitting converge to that of the receiving exponentially, that is, the effective traffic of each stream would be fair.

    Detergent soluble DNA from splenocytes of immunologically stimulated mice has been shown to incorporate [3H]dThd more rapidly than detergent insoluble DNA. In this report the author compares the incorporation of other 3H-labeled nucleosides and 3H-labeled deoxynucleosides and the distribution of 3H in the different size classes of detergent soluble DNA. The order of incorporation into DS DNA is [3H]dThd > [3H]dCyd > [3H]Ado > [3H]dGuo approx. = [3H]Cyd > [3H]dAdo > [3H]Guo. The author also shows that the previously reported slight enrichment in Gua + Cyt content is not due to preferential incorporation of dGuo or of dCyd into any one size class

    2009-09-08

    Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast. Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

    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.

  13. 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. Multi-Instance Learning with Any Hypothesis Class

    CERN Document Server

    Sabato, Sivan

    2011-01-01

    In the supervised learning setting termed Multiple-Instance Learning (MIL), the examples are bags of instances, and the bag label is a function of the labels of its instances. Typically, this function is the Boolean OR. The learner observes a sample of bags and the bag labels, but not the instance labels that determine the bag labels. The learner is then required to emit a classification rule for bags based on the sample. MIL has numerous applications, and many heuristic algorithms have been used successfully on this problem, each adapted to specific settings or applications. In this work we provide a unified theoretical analysis for MIL, which holds for any underlying hypothesis class, regardless of a specific application or problem domain. We show that the sample complexity of MIL is only poly-logarithmically dependent on the size of the bag, for any underlying hypothesis class. In addition, we introduce a new PAC-learning algorithm for MIL, which employs a regular supervised learning algorithm as an oracle...

    A common use of crowd sourcing is to obtain labels for a dataset. Several algorithms have been proposed to identify uninformative members of the crowd so that their labels can be disregarded and the cost of paying them avoided. One common motivation of these algorithms is to try and do without any initial set of trusted labeled data. We analyse this class of algorithms as mechanisms in a game-theoretic setting to understand the incentives they create for workers. We find an impossibility resu...

  17. Mindboggle: Automated brain labeling with multiple atlases

    International Nuclear Information System (INIS)

    To make inferences about brain structures or activity across multiple individuals, one first needs to determine the structural correspondences across their image data. We have recently developed Mindboggle as a fully automated, feature-matching approach to assign anatomical labels to cortical structures and activity in human brain MRI data. Label assignment is based on structural correspondences between labeled atlases and unlabeled image data, where an atlas consists of a set of labels manually assigned to a single brain image. In the present work, we study the influence of using variable numbers of individual atlases to nonlinearly label human brain image data. Each brain image voxel of each of 20 human subjects is assigned a label by each of the remaining 19 atlases using Mindboggle. The most common label is selected and is given a confidence rating based on the number of atlases that assigned that label. The automatically assigned labels for each subject brain are compared with the manual labels for that subject (its atlas). Unlike recent approaches that transform subject data to a labeled, probabilistic atlas space (constructed from a database of atlases), Mindboggle labels a subject by each atlas in a database independently. When Mindboggle labels a human subject's brain image with at least four atlases, the resulting label agreement with coregistered manual labels is significantly higher than when only a single atlas is used. Different numbers of atlases provide significantly higher label agreements for individual brain regions. Increasing the number of reference brains used to automatically label a human subject brain improves labeling accuracy with respect to manually assigned labels. Mindboggle software can provide confidence measures for labels based on probabilistic assignment of labels and could be applied to large databases of brain images

    2015-01-01

    In March 1937, when the first issue of Marie-Claire was published, the images of the female body it presented to its female readers from working-class backgrounds contrasted sharply with those featured in previous magazines. The female bodies are dressed and groomed to seduce and replace the hieratic bodies that presented fashions synonymous with membership in the upper classes. The present essay examines this shift and shows that the visual repertoire employed is borrowed from that of the fe...

    The Fourier class of integral transforms with kernels $B(\\omega r)$ has by definition inverse transforms with kernel $B(-\\omega r)$. The space of such transforms is explicitly constructed. A slightly more general class of generalized Fourier transforms are introduced. From the general theory foll...... follows that integral transform with kernels which are products of a Bessel and a Hankel function or which is of a certain general hypergeometric type have inverse transforms of the same structure....

  9. Photoaffinity Labeling of Plasma Proteins

    Masaki Otagiri

    2013-11-01

    Full Text Available Photoaffinity labeling is a powerful technique for identifying a target protein. A high degree of labeling specificity can be achieved with this method in comparison to chemical labeling. Human serum albumin (HSA and α1-acid glycoprotein (AGP are two plasma proteins that bind a variety of endogenous and exogenous substances. The ligand binding mechanism of these two proteins is complex. Fatty acids, which are known to be transported in plasma by HSA, cause conformational changes and participate in allosteric ligand binding to HSA. HSA undergoes an N-B transition, a conformational change at alkaline pH, that has been reported to result in increased ligand binding. Attempts have been made to investigate the impact of fatty acids and the N-B transition on ligand binding in HSA using ketoprofen and flunitrazepam as photolabeling agents. Meanwhile, plasma AGP is a mixture of genetic variants of the protein. The photolabeling of AGP with flunitrazepam has been utilized to shed light on the topology of the protein ligand binding site. Furthermore, a review of photoaffinity labeling performed on other major plasma proteins will also be discussed. Using a photoreactive natural ligand as a photolabeling agent to identify target protein in the plasma would reduce non-specific labeling.

  10. Radioisotope method for leucocyte labelling

    International Nuclear Information System (INIS)

    Whole blood leukocytes were labelled with 99mTc-sulphocolloid, which was selectively deposited in phagocytizing polymorphonuclear cells. To achieve optimal phagocytosis, the authors prepared 99mTc sulphocoloid from a Bulgarian kit. The required size of the colloid particles (1,2 μm) was achieved after 90-120 min storage at room temperature without rotation. Leucocytes were labelled by a proposed by the authors original method: to 10 ml heparinized blood 0,26-0,30 GB 99mTc sulphocolloid was added, incubated for 60 min; the free sulphocolloid was centrifuged in the syringe. The labelled cell sediment was suspended in physiological saline and re-injected. In a study of 16 patients on gamma camera, suspected of having inflammatory processes, the mean labelling effectiveness was 59%, similar to the one reported by other authors, who used similar technique and ready-made kits. Eight patients had positive finding, the inflammatory process in 7 being visualized as early as on hour 2 or 3 and in 1 on hour 24. The new method developed for specific leucocyte labelling with the use of Bulgarian kit may gain acceptance in the visualization of vague inflammatory processes. 3 figs., 4 refs

  12. Nutrition Labeling Using a Computer Program

    Science.gov (United States)

    Metzger, Lloyd E.

    The 1990 Nutrition Labeling and Education Act mandated nutritional labeling of most foods. As a result, a large portion of food analysis is performed for nutritional labeling purposes. A food labeling guide and links to the complete nutritional labeling regulations are available online at http://vm.cfsan.fda.gov/˜dms/flg-toc.html. However, interpretation of these regulations and the appropriate usage of rounding rules, available nutrient content claims, reference amounts, and serving size can be difficult.

  13. Controllable labelling of stem cells with a novel superparamagnetic iron oxide-loaded cationic nanovesicle for MR imaging

    International Nuclear Information System (INIS)

    To investigate the feasibility of highly efficient and controllable stem cell labelling for cellular MRI. A new class of cationic, superparamagnetic iron oxide nanoparticle (SPION)-loaded nanovesicles was synthesised to label rat bone marrow mesenchymal stem cells without secondary transfection agents. The optimal labelling conditions and controllability were assessed, and the effect of labelling on cell viability, proliferation activity and multilineage differentiation was determined. In 18 rats, focal ischaemic cerebral injury was induced and the rats randomly injected with 1 x 106 cells labelled with 0-, 8- or 20-mV nanovesicles (n = 6 each). In vivo MRI was performed to follow grafted cells in contralateral striata, and results were correlated with histology. Optimal cell labelling conditions involved a concentration of 3.15 μg Fe/mL nanovesicles with 20-mV positive charge and 1-h incubation time. Labelling efficiency showed linear change with an increase in the electric potentials of nanovesicles. Labelling did not affect cell viability, proliferation activity or multilineage differentiation capacity. The distribution and migration of labelled cells could be detected by MRI. Histology confirmed that grafted cells retained the label and remained viable. Stem cells can be effectively and safely labelled with cationic, SPION-loaded nanovesicles in a controllable way for cellular MRI. (orig.)

  14. Investigation of Bias in Continuous Medical Image Label Fusion.

    Directory of Open Access Journals (Sweden)

    Fangxu Xing

    Full Text Available Image labeling is essential for analyzing morphometric features in medical imaging data. Labels can be obtained by either human interaction or automated segmentation algorithms, both of which suffer from errors. The Simultaneous Truth and Performance Level Estimation (STAPLE algorithm for both discrete-valued and continuous-valued labels has been proposed to find the consensus fusion while simultaneously estimating rater performance. In this paper, we first show that the previously reported continuous STAPLE in which bias and variance are used to represent rater performance yields a maximum likelihood solution in which bias is indeterminate. We then analyze the major cause of the deficiency and evaluate two classes of auxiliary bias estimation processes, one that estimates the bias as part of the algorithm initialization and the other that uses a maximum a posteriori criterion with a priori probabilities on the rater bias. We compare the efficacy of six methods, three variants from each class, in simulations and through empirical human rater experiments. We comment on their properties, identify deficient methods, and propose effective methods as solution.

  16. Correlative microscopy of densely labeled projection neurons using neural tracers

    Daniele Oberti

    2010-06-01

    Full Text Available Three-dimensional morphological information about neural microcircuits is of high interest in neuroscience, but acquiring this information remains challenging. A promising new correlative technique for brain imaging is array tomography (Micheva and Smith, 2007, in which series of ultrathin brain sections are treated with fluorescent antibodies against neurotransmitters and synaptic proteins. Treated sections are repeatedly imaged in the fluorescence light microscope (FLM and then in the electron microscope (EM. We explore a similar correlative imaging technique in which we differentially label distinct populations of projection neurons, the key routers of electrical signals in the brain. In songbirds, projection neurons can easily be labeled using neural tracers, because the vocal control areas are segregated into separate nuclei. We inject tracers into areas afferent and efferent to the main premotor area for vocal production, HVC, to retrogradely and anterogradely label different classes of projection neurons. We optimize tissue preparation protocols to achieve high fluorescence contrast in the FLM and good ultrastructure in the EM (using osmium tetroxide. Although tracer fluorescence is lost during EM preparation, we localize the tracer molecules after fixation and embedding by using fluorescent antibodies against them. We detect signals mainly in somata and dendrites, allowing us to classify synapses within a single ultrathin section as belonging to a particular type of projection neuron. The use of our method will be to provide statistical information about connectivity among different neuron classes, and to elucidate how signals in the brain are processed and routed among different areas.

  17. Positron emitter labeled enzyme inhibitors

    International Nuclear Information System (INIS)

    This invention involves a new strategy for imagining 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 inactivators 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

    Let M be an n-manifold, and let A be a space with a partial sum behaving as an n-fold loop sum. We define the space C(M;A) of configurations in M with summable labels in A via operad theory. Some examples are symmetric products, labelled configuration spaces, and spaces of rational curves. We show that C(I^n,dI^n;A) is an n-fold delooping of C(I^n;A), and for n=1 it is the classifying space by Stasheff. If M is compact, parallelizable, and A is path connected, then C(M;A) is homotopic to the ...

    Full Text Available The need for denture labeling is important for forensic and social reasons in case patients need to be identified individually. The importance of denture marking has long been acknowledged by the dental profession. Over the years, various denture marking systems have been reported in the literature, but none till date fulfills all the prescribed ADA specifications. A simple, easy, inexpensive procedure for marking accurate identification marks on dentures with a lead foil is described here. The label caring the patient information is incorporated in the acrylic resin during the denture processing.

  20. The chemistry of 99mTc-labeled radiopharmaceuticals

    International Nuclear Information System (INIS)

    The subject of the chemistry of 99mTc-radiopharmaceuticals consists of a collection of bits and pieces of information without a unifying theme. Since the initial impetus to the field of organ imaging was provided by radiochemists, nuclear chemists, and clinician-investigators, using easily prepared 99mTc-compounds from available off-the-shelf ligands, complete chemical characterization was not carried for the 99mTc-radiopharmaceuticals and their metabolites. The influx of coordination, organic, and analytic chemists and their systematic studies clarified some of the structures of these tracers, and promoted the general synthetic methods of a variety of ligands and the corresponding 99mTc-chelates as well as understanding of the nature of their metabolites. Although major developments for organ-imaging radiopharmaceuticals had been made, future studies will result in the simplified methodology of protein-labeling, fine-tuning of the currently available radiopharmaceuticals for higher organ-extraction, and replacement of expensive 123I-labeled tracers with the corresponding 99mTc-tracers. In general, the Tc-complexes are thermodynamically less stable and kinetically more labile than the corresponding Re-complexes. The well established chemistry of Re-compounds, the similarity of Tc-chemistry to that of Re compounds, and structure-activity relationships of a few classes of 99mTc-labeled compounds, may promote the development of new generation of 99mTc-labeled radiopharmaceuticals.69 references

  1. Manifold regularized non-negative matrix factorization with label information

    Science.gov (United States)

    Li, Huirong; Zhang, Jiangshe; Wang, Changpeng; Liu, Junmin

    2016-03-01

    Non-negative matrix factorization (NMF) as a popular technique for finding parts-based, linear representations of non-negative data has been successfully applied in a wide range of applications, such as feature learning, dictionary learning, and dimensionality reduction. However, both the local manifold regularization of data and the discriminative information of the available label have not been taken into account together in NMF. We propose a new semisupervised matrix decomposition method, called manifold regularized non-negative matrix factorization (MRNMF) with label information, which incorporates the manifold regularization and the label information into the NMF to improve the performance of NMF in clustering tasks. We encode the local geometrical structure of the data space by constructing a nearest neighbor graph and enhance the discriminative ability of different classes by effectively using the label information. Experimental comparisons with the state-of-the-art methods on theCOIL20, PIE, Extended Yale B, and MNIST databases demonstrate the effectiveness of MRNMF.

  2. Connected Component Labeling Using Components Neighbors-Scan Labeling Approach

    Directory of Open Access Journals (Sweden)

    Akmal Rakhmadi

    2010-01-01

    Full Text Available Problem statement: Many approaches have been proposed in previous such as the classic sequential connected components labeling algorithm which is relies on two subsequent raster-scans of a binary image. This method produced good performance in terms of accuracy, but because of the implementation of the image processing systems now requires faster process of the computer, the speed of this technique’s process has become an important issue. Approach: A computational approach, called components neighbors-scan labeling algorithm for connected component labeling was presented in this study. This algorithm required scanning through an image only once to label connected components. The algorithm started by scanning from the head of the component’s group, before tracing all the components neighbors by using the main component’s information. This algorithm had desirable characteristics, it is simple while promoted accuracy and low time consuming. By using a table of components, this approach also gave other advantages as the information for the next higher process. Results: The approach had been tested with a collection of binary images. In practically all cases, the technique had successfully given the desired result. Averagely, from the results the algorithm increased the speed around 67.4% from the two times scanning method. Conclusion: Conclusion from the comparison with the previous method, the approach of components neighbors-scan for connected component labeling promoted speed, accuracy and simplicity. The results showed that the approach has a good performance in terms of accuracy, the time consumed and the simplicity of the algorithm.

    Full Text Available The problem of translation in foreign language classes cannot be dealt with unless we attempt to make an overview of what translation meant for language teaching in different periods of language pedagogy. From the translation-oriented grammar-translation method through the complete ban on translation and mother tongue during the times of the audio-lingual approaches, we have come today to reconsider the role and status of translation in ESL classes. This article attempts to advocate for translation as a useful ESL class activity, which can completely fulfil the requirements of communicativeness. We also attempt to identify some activities and games, which rely on translation in some books published in the 1990s and the 2000s.

  14. Labeling of the cerebellar peduncles using a supervised Gaussian classifier with volumetric tract segmentation

    Ye, Chuyang; Bazin, Pierre-Louis; Bogovic, John A.; Ying, Sarah H.; Prince, Jerry L.

    2012-02-01

    The cerebellar peduncles are white matter tracts that play an important role in the communication of the cerebellum with other regions of the brain. They can be grouped into three fiber bundles: inferior cerebellar peduncle middle cerebellar peduncle, and superior cerebellar peduncle. Their automatic segmentation on diffusion tensor images would enable a better understanding of the cerebellum and would be less time-consuming and more reproducible than manual delineation. This paper presents a method that automatically labels the three fiber bundles based on the segmentatin results from the diffusion oriented tract segmentation (DOTS) algorithm, which achieves volume segmentation of white matter tracts using a Markov random field (MRF) framework. We use the DOTS labeling result as a guide to determine the classification of fibers produced by wild bootstrap probabilistic tractography. Mean distances from each fiber to each DOTS volume label are defined and then used as features that contribute to classification. A supervised Gaussian classifier is employed to label the fibers. Manually delineated cerebellar peduncles serve as training data to determine the parameters of class probabilities for each label. Fibers are labeled ad the class that has the highest posterior probability. An outlier detection ste[ re,pves fober tracts that belong to noise of that are not modeled by DOTS. Experiments show a successful classification of the cerebellar peduncles. We have also compared results between successive scans to demonstrate the reproducibility of the proposed method.

    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.

  17. AN EMPIRICAL COMPARISON OF WEIGHTING FUNCTIONS FOR MULTI-LABEL DISTANCEWEIGHTED K-NEAREST NEIGHBOUR METHOD

    Directory of Open Access Journals (Sweden)

    Jianhua Xu

    2011-09-01

    Full Text Available Multi-label classification is an extension of classical multi-class one, where any instance can be associated with several classes simultaneously and thus the classes are no longer mutually exclusive. It was experimentally shown that the distance-weighted k-nearest neighbour (DWkNN algorithm is superior to the original kNN rule for multi-class learning. But, it has not been investigated whether the distance-weighted strategy is valid for multi-label learning and which weighting function performs well. In this paper, we provide a concise multi-label DWkNN form (MLC-DWkNN. Furthermore, four weighting functions, Dudani’s linear function varying from 1 to 0, Macleod’s linear function ranging from 1 to 1/2, Dudani’s inverse distance function, and Zavrel’s exponential function, are collected and then investigated by detailed experiments on three benchmark data sets with Manhattan distance. Our study demonstrates that Dudani’s linear and Zavrel’s exponential functions work well, and moreover MLC-DWkNN with such two functions outperforms an existing kNN-based multi-label classifier ML-kNN.

  4. Adeus à classe trabalhadora?

    2013-12-01

    Full Text Available No início da década de 1980, a política centrada em classes da tradição socialista estava em crise, e comentadores importantes adotaram tons apocalípticos. No final da década, a esquerda permanecia profundamente dividida entre os advogados da mudança e os defensores da fé. Em meados dos anos 1990, os primeiros tinham, de modo geral, ganhado a batalha. O artigo busca apresentar essa mudança contemporânea não como a 'morte da classe', mas como o desa­parecimento de um tipo particular de ­sociedade de classes, marcado pelo ­processo de formação da classe trabalhadora entre os anos 1880 e 1940 e pelo alinhamento político daí resultante, atingindo seu apogeu na construção social-democrata do acordo do pós-guerra. Quando mudanças de longo prazo na economia se combinaram com o ataque ao keynesianismo na política de recessão a partir de meados da década de 1970, a unidade da classe trabalhadora deixou de estar disponível da forma antiga e bastante utilizada, como o terreno natural da política de esquerda. Enquanto uma coletividade dominante da classe trabalhadora entrou em declínio, outra se corporificou de modo lento e desigual para tomar o lugar daquela. Mas a unidade operacional dessa nova agregação da classe trabalhadora ainda está, em grande parte, em formação. Para recuperar a eficácia política da tradição socialista, alguma nova visão de agência política coletiva será necessária, uma visão imaginativamente ajustada às condições emergentes da produção e acumulação capitalista no início do século XXI.

  5. A Multi-Label Classification Approach Based on Correlations Among Labels

    Full Text Available Multi label classification is concerned with learning from a set of instances that are associated with a set of labels, that is, an instance could be associated with multiple labels at the same time. This task occurs frequently in application areas like text categorization, multimedia classification, bioinformatics, protein function classification and semantic scene classification. Current multi-label classification methods could be divided into two categories. The first is called problem transformation methods, which transform multi-label classification problem into single label classification problem, and then apply any single label classifier to solve the problem. The second category is called algorithm adaptation methods, which adapt an existing single label classification algorithm to handle multi-label data. In this paper, we propose a multi-label classification approach based on correlations among labels that use both problem transformation methods and algorithm adaptation methods. The approach begins with transforming multi-label dataset into a single label dataset using least frequent label criteria, and then applies the PART algorithm on the transformed dataset. The output of the approach is multi-labels rules. The approach also tries to get benefit from positive correlations among labels using predictive Apriori algorithm. The proposed approach has been evaluated using two multi-label datasets named (Emotions and Yeast and three evaluation measures (Accuracy, Hamming Loss, and Harmonic Mean. The experiments showed that the proposed approach has a fair accuracy in comparison to other related methods.

    We propose an image labeling method for LIDAR intensity image obtained by Mobile Mapping System (MMS) using K-Nearest Neighbor (KNN) of feature obtained by Convolutional Neural Network (CNN). Image labeling assigns labels (e.g., road, cross-walk and road shoulder) to semantic regions in an image. Since CNN is effective for various image recognition tasks, we try to use the feature of CNN (Caffenet) pre-trained by ImageNet. We use 4,096-dimensional feature at fc7 layer in the Caffenet as the descriptor of a region because the feature at fc7 layer has effective information for object classification. We extract the feature by the Caffenet from regions cropped from images. Since the similarity between features reflects the similarity of contents of regions, we can select top K similar regions cropped from training samples with a test region. Since regions in training images have manually-annotated ground truth labels, we vote the labels attached to top K similar regions to the test region. The class label with the maximum vote is assigned to each pixel in the test image. In experiments, we use 36 LIDAR intensity images with ground truth labels. We divide 36 images into training (28 images) and test sets (8 images). We use class average accuracy and pixel-wise accuracy as evaluation measures. Our method was able to assign the same label as human beings in 97.8% of the pixels in test LIDAR intensity images.

  12. Ivabradine: A Review of Labeled and Off-Label Uses.

    Science.gov (United States)

    Oliphant, Carrie S; Owens, Ryan E; Bolorunduro, Oluwaseyi B; Jha, Sunil K

    2016-10-01

    Ivabradine is a unique medication recently approved in the USA for the treatment of select heart failure patients. It was first approved for use in several countries around the world over a decade ago as an anti-anginal agent, with subsequent approval for use in heart failure patients. Since ivabradine has selective activity blocking the I f currents in the sinus node, it can reduce heart rate without appreciable effects on blood pressure. Given this heart-rate-specific effect, it has been investigated in many off-label indications as an alternative to traditional heart-rate-reducing medications such as beta blockers and calcium channel blockers. We conducted searches of PubMed and Google Scholar for ivabradine, heart failure, HFrEF, HFpEF, angina, coronary artery disease, inappropriate sinus tachycardia, postural orthostatic hypotension, coronary computed tomography angiography and atrial fibrillation. We reviewed and included studies, case reports, and case series published between 1980 and June 2016 if they provided information relevant to the practicing clinician. In many cases, larger clinical trials are needed to solidify the benefit of ivabradine, although studies indicate benefit in most therapeutic areas explored to date. The purpose of this paper is to review the current labeled and off-label uses of ivabradine, with a focus on clinical trial data. PMID:27405864

  15. Radioimmunoassay for antigliadin-antibodies using 14C-labelled gliadin

    International Nuclear Information System (INIS)

    A sensitive radioimmunoassay for antibodies to gliadin has been developed. Gliadin from wheat gluten was labelled with [1-14C]acetic anhydride to a specific activity of 2.6 x 106 dpm/mg. Immunological evidence is presented that the antigen was not essentially altered by the labelling procedure. Experimentally-induced antigliadin antibodies or sera of patients with coeliac disease (CD) were reacted with labelled gliadin and the immune complexes formed precipitated by antiglobulin. Precipitating antibodies were determined by incubating CD sera with labelled gliadin and measuring the radioacticity in precipitates formed without the addition of second antibody. Comparison with other methods for the detection of antigliadin antibodies, including immunoelectrophoresis, immunodiffusion and passive hemagglutination indicated that total and precipitating antibodies were determined only by RIA. The assay also provides information on the immunoglobulin class of antigliadin-antibodies present in sera of patients with coeliac disease

  16. Radioimmunoassay for anticollagen-antibodies using 14C-labelled collagen

    International Nuclear Information System (INIS)

    A sensitive radioimmunoassay for anticollagen antibodies is described. 14C-labelled human acid-soluble collagen of high specific activity (5 x 106 dpm/mg) is used as antigen either in native or denatured state. Experimentally induced anticollagen antibodies or RA synovial fluids containing antibodies to collagen are reacted with the labelled antigen. The immune complexes formed are precipitated with goat antiserum to rabbit globulins ('second antibody'). A systematic investigation of the labelled collagen in regard to cleavage by enzymes, fibril formation and specificity showed that no gross alteration had been caused by the labelling procedure. The assay furnishes information on the avidity, specificity and immunoglobulin class of experimental or pathological anticollagen antibodies. It can also be used as sensitive assay for collagen in biological fluids

    Full Text Available Phenolic phytochemicals are a broad class of nutraceuticals found in plants which have been extensively researched by scientists for medicinal potential. Eugenol, a phenolic natural compound available in the essential oils primarily extracted from clove plants, has been exploited for various medicinal applications. It possesses antioxidant, antimutagenic, antigenotoxic, anti-inflammatory and anticancer properties. The goal of current study was to extract Eugenol compound from clove plant and radiolabel the eugenol with 131I which is a well known radioisotope for imaging and therapy in Nuclear Medicine by utilizing iodogen method. The yield of radiolabeling of Eugenol (131I-E was calculated over 80% by Thin Layer Radio Chromatography and High Performance Liquid Radio Chromatograpy methods. Structural analysis of Eugenol was confirmed by Liguid Chromatography Mass Spectroscopy. Lipophilicity and stability studies were performed. Due to the attachment of iodine to Eugenol, radioiodinated Eugenol was more lipophilic. Stability of 131I-E was appropriate for study period. All experimental results suggest that 131I labeled Eugenol compound may be used in the applications of Nuclear Medicine as a radiolabeled agent for imaging and therapy on various cancer types.

  18. 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

  5. 201Tl labelled myocardium tomoscanning

    International Nuclear Information System (INIS)

    A new device, the J and P Tomoscanner, enables us to obtain the transverse scintigraphic section of any organ labelled by a single photon emitting radionuclide. For the time being, this technique has been used mainly for brain and liver studies. This work explores the ability of this tomograph to furnish sections of the 201Tl labelled myocardium by comparing them with the scintillation gamma-camera images. Towards this aim, witnesses and patients with documented anterior or lateral infarctus have been studied. Our actual results show a high correlation between the two explorations. But, by means of the section, both the site and size of the necrosis are visualized. However, only a single tomographic image was obtained in each patient because of the time necessary for its retranscription on paper. In the near future, when it will be possible to perform routinely several sections, a better size estimation will be possible

  6. Multi-class open set recognition for SAR imagery

    Science.gov (United States)

    Scherreik, Matthew; Rigling, Brian

    2016-05-01

    Supervised multi-class target recognition algorithms label an input pattern according to the most similar training class. Typically, the number of training classes is fixed and known a priori. In practice, however, a classifier may encounter novel targets that were not seen in training and label them incorrectly. Recent work in open set recognition (OSR) develops classifiers that can identify training targets as well as previously unknown targets. This results in a reduced number of forced misclassifications by "ejecting" targets that were not present in training. Several OSR algorithms are based on support vector machines (SVMs), namely, the 1-vs-set machine, W-SVM, and POS-SVM. The 1-vs-set machine, a linear classifier, forms a "lab" around each training class to discriminate it from the remaining training classes and limit the risk of labeling open space as target space. The W-SVM uses a novel dual-calibration technique to map the SVM outputs to posterior probabilities, which are then subjected to a pair of user-specified thresholds. The POS-SVM relies on a single calibration step, but features data-driven posterior probability thresholds that are chosen automatically. Both the W-SVM and POS-SVM have the capability to use nonlinear SVM kernel functions and perform particularly well with the popular Gaussian RBF kernel. Past works have shown that these algorithms can be effective for classifying ladar and IR images with a rejection option. In this paper, we apply these algorithms to the MSTAR SAR dataset and analyze their performance for classifying known targets and rejecting unknown targets in the presence of clutter.

  7. Divide and Merge Classification for High Dimensional Multi-Class Datasets

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available If a dataset has multiple classes and huge features like microarray data, classification accuracy may be low, even though feature selections are applied to reduce the dimensions of the dataset. Improvement of classification accuracy for the dataset is a challenging task. We propose an efficient classification method based on the "Divide-and-Merge" approach for high dimensional multi-class datasets. In the proposed method, we extracted different feature subsets for each class in an original dataset and generate new datasets. Unknown sample Si is classified into the new datasets and the results are merged for a final decision of the class label.

    A method is described for preparing radioactively labelled vitamin B 12 (cyanocobalamin) by reacting α-(5,6-dimethylbenzimidazolyl) hydrogenobamide with active (sup(57,58)Co) cobaltous ion. The latter may be in the form of cobaltous chloride or sulphate in aqueous or aqueous alcoholic medium. The reaction is effected by heating the reactants in darkness at pH 4 to 8. An excess of cyanide is added to convert the hydroxocobalamin formed to cyanocobalamin. (U.K.)

  10. Different sources of reduced carbon contribute to form three classes of terpenoid emitted by Quercus ilex L. leaves

    International Nuclear Information System (INIS)

    Quercus ilex L. leaves emit terpenes but do not have specialized structures for terpene storage. We exploited this unique feature to investigate terpene biosynthesis in intact leaves of Q. ilex. Light induction allowed us to distinguish three classes of terpenes: (i) a rapidly induced class including alpha-pinene; (ii) a more slowly induced class, including cis-beta-ocimene; and (iii) the most slowly induced class, including 3-methyl-3-buten-1-ol. Using 13C, we found that alpha-pinene and cis-beta-ocimene were labeled quickly and almost completely while there was a delay before label appeared in linalool and 3-methyl-3-buten-1-ol. The acetyl group of 3-methyl-3-buten-1-yl acetate was labeled quickly but label was limited to 20% of the moiety. It is suggested that the ocimene class of monoterpenes is made from one or more terpenes of the alpha-pinene class and that both classes are made entirely from reduced carbon pools inside the chloroplasts. Linalool and 3-methyl-3-buten-1-ol are made from a different pool of reduced carbon, possibly in nonphotosynthetic plastids. The acetyl group of the 3-methyl-3-buten-1-yl acetate is derived mostly from carbon that does not participate in photosynthetic reactions. Low humidity and prolonged exposure to light favored ocimenes emission and induced linalool emission. This may indicate conversion between terpene classes

  11. Biomolecule labelling by 186 Re

    International Nuclear Information System (INIS)

    The aim of this study is to develop and improve the existing radiolabelling techniques of peptides and monoclonal antibodies with 186 Re and 188 Re as potential agents for cancer targeted radiotherapy. We selected the following methods and techniques for direct labelling of peptides and monoclonal antibody: 1. Prereduction of -S-S- bridges of biomolecule to sulfhydryls using reducing agents: ascorbic acid, cysteine, active hydrogen, 2,3 dimercaptopropanol. The prereduction reactions are controlled by massic ratios of reduction agents/biomolecule, pH, temperature and time of incubation; 2. Reduction of 186 Re O4- stannous chloride in acid and alkaline pH; 3. Coupling reaction of 186 Re (red) with the biomolecule controlled by the time and temperature of incubation, the influence of pH regarding the binding of 186 Re to the biomolecules. The quality control was effected by chromatography techniques (paper and elution gel chromatography) on labeled biomolecule before and after purification. The elution gel chromatography was spectrophotometricaly monitored at 280 nm. In the same time the radioactivity of samples was measured using a gamma counter. All the results confirm in vitro stability of labeled biomolecule. The biological evaluation studies regarding accumulation and biological affinity will be controlled by scintigraphy method. Biodistribution studies will be effected to Walker tumor bearing animals at 4 and 24 hours after injections. (authors)

  13. Utilisation and off-label prescriptions of respiratory drugs in children.

    Directory of Open Access Journals (Sweden)

    Sven Schmiedl

    Full Text Available Respiratory drugs are widely used in children to treat labeled and non-labeled indications but only some data are available quantifying comprehensively off-label usage. Thus, we aim to analyse drug utilisation and off-label prescribing of respiratory drugs focusing on age- and indication-related off-label use. Patients aged ≤18 years documented in the Bavarian Association of Statutory Health Insurance Physicians database (approx. 2 million children between 2004 and 2008 were included in our study. Annual period prevalence rates (PPRs per 10,000 children and the proportion of age- and indication-related off-label prescriptions were calculated and stratified by age and gender. Within the study period, highest PPRs were found for the fixed combination of clenbuterol/ambroxol (between 374-575 per 10,000 children and the inhaled short acting beta-2-agonist salbutamol (between 378-527 per 10,000 children. Highest relative PPR increase was found for oral salbutamol (approx. 39-fold whereas the most distinct decrease was found for oral long-acting beta-2-agonist clenbuterol (-97%. Compound classes most frequently involved in off-label prescribing were inhaled bronchodilative compounds (91,402; 37.3% and oral beta-2-agonists (26,850; 22.5%. The highest absolute number of off-label prescriptions were found for inhaled salbutamol (n = 67,084; 42.0% and oral clenbuterol/ambroxol (fixed combination, n = 18,897; 20.7%. Off-label prescribing due to indication was of much greater relevance than age-related off-label use. Most frequently, bronchodilative compounds were used off-label to treat respiratory tract infections. Highest off-label prescription rates were found in the youngest patients without relevant gender-related differences. Off-label prescribing of respiratory drugs is common especially in young children. Bronchodilative drugs were most frequently used off-label for treating acute bronchitis or upper respiratory tract infections

    The early events of the dengue virus life cycle involve virus binding, internalization, trafficking, and fusion. Fluorescently labeled viruses can be used to visualize these early processes. As dengue virus has 180 identical copies of the envelope protein attached to the membrane surface and is surrounded by a lipid membrane, amine-reactive (Alexa Fluor) or lipophilic (DiD) dyes can be used for virus labeling. These dyes are highly photostable and are ideal for studies involving cellular uptake and endosomal transport. To improve virus labeling efficiency and minimize the nonspecific labeling of nonviral proteins, virus concentration and purification precede fluorescent labeling of dengue viruses. Besides using these viruses for single-particle tracking, DiD-labeled viruses can also be used to distinguish serotype-specific from cross-neutralizing antibodies. Here the details of virus concentration, purification, virus labeling, applications, and hints of troubleshooting are described. PMID:24696327

    This paper reports on the utilization of tagged epsilon carbon of DL-lysine by a dog both anemic and hypoproteinemic due to repeated bleeding plus a diet low in protein. The experiment extended over period of 234 days, a time sufficient to indicate an erythrocyte life span of at least 115 days based upon the rate of replacement of labeled red cell proteins. The proteins of broken down red cells seem not to be used with any great preference for the synthesis of new hemoglobin.

    Full Text Available Abstract The review presents pediatric adverse drug events from a historical perspective and focuses on selected safety issues associated with off-label use of medications for the psychiatric treatment of youth. Clinical monitoring procedures for major psychotropic drug classes are reviewed. Prior studies suggest that systematic treatment monitoring is warranted so as to both minimize risk of unexpected adverse events and exposures to ineffective treatments. Clinical trials to establish the efficacy and safety of drugs currently being used off-label in the pediatric population are needed. In the meantime, clinicians should consider the existing evidence-base for these drugs and institute close clinical monitoring.

  13. Label transfer by measuring compactness.

    Science.gov (United States)

    Varga, Robert; Nedevschi, Sergiu

    2013-12-01

    This paper presents a new automatic image annotation algorithm. First, we introduce a new similarity measure between images: compactness. This uses low level visual descriptors for determining the similarity between two images. Compactness shows how close test image features lie to training image feature cluster centers. The measure provides the core for a k-nearest neighbor type image annotation method. Afterward, a formalism for defining different transfer techniques is devised and several label transfer techniques are provided. The method as whole is evaluated on four image annotation benchmarks. The results on these sets validate the accuracy of the approach, which outperforms many state-of-the-art annotation methods. The method presented here requires a simple training process, efficiently combines different feature types and performs better than complex learning algorithms, even in this incipient form. The main contributions of this paper are the usage of compactness as a similarity measure that enables efficient low level feature comparison and an annotation algorithm based on label transfer.

  15. 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

  16. Radiopharmaceutical potential of I-131 labelled diazepam

    International Nuclear Information System (INIS)

    In this study, diazepam is a derivative of the 1.4 benzodiazepine family that the most widely used drug as anticonvulsant agent has been labeled with I-131, as a new radiopharmaceutical and its radiopharmaceutical potential has been determined. Labeling of diazepam has been performed by iodogen method and optimum labeling conditions have been determined. Optimum reaction conditions are 1 mg for iodogen amount; 1-5 mg for diazepam amount, 15-20 minutes for reaction time and room temperature for reaction temperature. Specific activity of labeled compound was 0,15 Ci/mmol level. N-octanol/water ratio was found 1.9 for 131IDZ (131I labeled diazepam). In vivo experiments have been carried out to determine radiopharmaceutical potentials of labeled compound. Biodistribution studies on rats showed that 131IDZ have accumulated in kidneys, liver, lungs and brain tissues. Scintigraphic results taken with gamma camera on rabbits agree with biodistribution results of rats. (author)

    The irradiation test of bar code label tagged on radioactive waste container was done to determine the effect of radiation. Low and medium radioactive waste is that below total activity of 4,000Bq/g according to the Korean nuclear law. The irradiation amount to radiate bar code label tagged on radioactive waste container was calculated by MCNP-4b computer code. The nuclide such as Co-60 and Cs-137 was assumed to contribute 50 % of total activity. Real irradiation amount for bar code label was finally calculated by the dimensions of the container and the bar code label. The identification of post and the physical deflection of irradiated bar code label was tested by the bar code reader. The coated bar code label was suitable to use on low and medium radioactive waste container

  18. Green power: naturemade - History of a label

    International Nuclear Information System (INIS)

    This article presents the history of the set of 'naturemade' labels that are used to designate power generated in facilities that use renewable energy. Electricity from hydropower, wind-power, biogas and solar energy plants that fulfil particular ecological conditions receives a special label, 'Naturemade Star'. 'Normal' hydropower can be awarded the 'Naturemade Basic' label. The development of the labels is discussed in the light of increasing liberalisation of European electricity markets and increasing sales of 'green power' by electricity utilities. The need for certification of production facilities and the founding of the label's certification authority, the 'Verein fuer umweltgerechte Elektrizitaet' (VUE), a society for the promotion of environment-friendly electricity, are discussed. Criticisms made by certain environmental protection organisations on the awarding of the 'Naturemade Basic' label to projects that in their opinion do not help protect the environment are quoted. The article is completed with an interview on the subject with Ursula Stocker from the VUE

    Harrits, Gitte Sommer

    In this paper, I argue that claims about the death of class and the coming of the classless society are premature. Such claims are seldom genuinely empirical, and the theoretical argument often refers to a simple and therefore easily dismissible concept of class. By rejecting the concept of class...... altogether, sociological theory runs the risk of loosing the capacity for analysing stratification and vertical differentiation of power and freedom, which in late modernity seem to be a of continuing importance. Hence, I argue that although class analysis faces a number of serious challenges, it is possible...... to reinvent class analysis. The sociology of Pierre Bourdieu in many ways introduces an appropriate paradigm, and the paper therefore critically discusses Bourdieu's concept of class. Since the "Bourdieuan" class concept is primarily epistemological, i.e. a research strategy more than a theory...

    The concepts of fuzzy labeling and fuzzy magic labeling graph are introduced. Fuzzy magic labeling for some graphs like path, cycle, and star graph is defined. It is proved that every fuzzy magic graph is a fuzzy labeling graph, but the converse is not true. We have shown that the removal of a fuzzy bridge from a fuzzy magic cycle with odd nodes reduces the strength of a fuzzy magic cycle. Some properties related to fuzzy bridge and fuzzy cut node have also been discussed.

  14. A Review of the Ingredients Contained in Over the Counter (OTC Cough Syrup Formulations in Kenya. Are They Harmful to Infants?

    Directory of Open Access Journals (Sweden)

    Gabriel Kigen

    Full Text Available Cough syrups are widely used in the developing world, but safety of their use in infants and children less than two years has not been well documented. Some syrups contain multiple combinations of such drugs as promethazine, diphenhydramine and ephedrine; which are individually now contraindicated in children less than two years. Despite this, the syrups are available as over the counter drugs and may be dispensed to mothers who are unaware of the potentially hazardous effects to their infants. A descriptive cross-sectional study was used to investigate suitability of cough syrups sold within Eldoret municipality for use in children less than two years of age based on their formulations and available literature.Two semi-structured questionnaires were administered to pharmacy attendants and mothers attending sick child clinic at a referral hospital to establish whether cough syrups containing more than one active ingredient of compounds, now contraindicated in children are administered to infants, and awareness of potential serious adverse effects. Data from labeled contents of cough syrups from retail pharmacies was recorded and corroborated with information from literature to determine those deemed to contain the ingredients. The second questionnaire was administered to mothers with children less than two years to ascertain whether they had used the identified syrups. A total of 260 mothers and 55 pharmacy attendants were interviewed.There was widespread use of the syrups in children, including infants, with 192 (74% of the respondents having used identified syrups and over 90% of these on children less than 2 years including those less than three months.146 (76% mothers had administered the syrup at double the recommended dose.The regulatory authorities should make concerted efforts to discourage use of cough syrups containing ingredients that pose adverse events to infants, including campaigns to educate pharmacy workers and mothers.

It was synthesized by five steps from 3-methoxysalicylic acid. [131I]epidepride was obtained in 97.3% radiochemical yields from the corresponding 5-(tributyltin) derivative using hydrogen peroxide as the oxidant. The aryltin precursor was prepared from non-labelled epidepride by palladium-catalyzed stannylene using bis (tri-n-butyltin) in triethylamine. [131I] epidepride was stable under 4 degree C, and partition coefficient was 72.3 at pH 7.40. The biodistribution study in rats exhibited high localization in the striatum of the brain with the striatum/cerebellum ratio reaching 237/1 at 320 min postinjection. All these results suggest that [131I] epidepride may be used widely as a useful dopamine D2 receptor imaging agent for SPECT

    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

    Full Text Available This study explores the Malaysian consumers’ trust of an eco-label and the influence it has in their choice for the corresponding environment friendly product. Taking into consideration the infancy stage of the Malaysia green marketing initiative, traditional approach to evaluating local consumer receptiveness to the eco-label might not be suitable. This paper approaches the introduction of eco-label with two perspectives in mind. Firstly, while earlier studies from the western scholars use eco-label as a part of the augmented product, this study introduces eco-label as a separate moderating variable. Secondly, the choice of employees working in ISO14001 certified organizations as the population explore a potentially conducive place to initiate a systematic effort in developing a green consumer community. The result is very encouraging. This study has shown that, with some exposure to environmental related experiences Malaysian consumer would indeed react positively to the eco-label. In fact, for situation that requires them to consider environmental aspects of a product that they wish to purchase, the eco-label will definitely be the crucial factor that will push them to make the right purchase choice.

    Hauenschild, Till; Reichenwallner, Jörg; Enkelmann, Volker; Hinderberger, Dariush

    2016-08-26

    Drug binding to human serum albumin (HSA) has been characterized by a spin-labeling and continuous-wave (CW) EPR spectroscopic approach. Specifically, the contribution of functional groups (FGs) in a compound on its albumin-binding capabilities is quantitatively described. Molecules from different drug classes are labeled with EPR-active nitroxide radicals (spin-labeled pharmaceuticals (SLPs)) and in a screening approach CW-EPR spectroscopy is used to investigate HSA binding under physiological conditions and at varying ratios of SLP to protein. Spectral simulations of the CW-EPR spectra allow extraction of association constants (KA ) and the maximum number (n) of binding sites per protein. By comparison of data from 23 SLPs, the mechanisms of drug-protein association and the impact of chemical modifications at individual positions on drug uptake can be rationalized. Furthermore, new drug modifications with predictable protein binding tendency may be envisaged. PMID:27460503

    Benzimidazole carbamates (BZCs) act as inhibitors of the tubulin-microtubule equilibria in eukaryotic organisms. Recently drug resistance to this class of compounds in helminth parasites has been shown to be due to a reduced ability of resistant tubulin to bind BZCs. In order to quantitate the nature of the tubulin-BZC interaction a general method for the specific tritium labelling of BZCs has been developed. The BZCs: mebendazole, oxfendazole, parbendazole, oxibendazole, albendazole and fenbendazole were labelled by catalytic exchange using palladium on calcium carbonate in pure dioxane at 60{sup 0}C under tritium gas. The position of label incorporation for tritiated albendazole was determined by tritium-NMR as the 4-position of benzimadazole nucleus. The yields for individual BZCs varied from 8 to 68% for a range of specific activity of 0.44 to 13.4 Ci/mmole. (author).

    2011-01-01

    Label propagation has proven to be a fast method for detecting communities in large complex networks. Recent developments have also improved the accuracy of the approach, however, a general algorithm is still an open issue. We present an advanced label propagation algorithm that combines two unique strategies of community formation, namely, defensive preservation and offensive expansion of communities. Two strategies are combined in a hierarchical manner, to recursively extract the core of the network, and to identify whisker communities. The algorithm was evaluated on two classes of benchmark networks with planted partition and on almost 25 real-world networks ranging from networks with tens of nodes to networks with several tens of millions of edges. It is shown to be comparable to the current state-of-the-art community detection algorithms and superior to all previous label propagation algorithms, with comparable time complexity. In particular, analysis on real-world networks has proven that the algorithm ...

  5. Tritium labelling of two new analgesic drugs

    International Nuclear Information System (INIS)

    The labelling with tritium of two arylpropionic esters was studied. The synthesis between 3H-Ibuprofen and the two unlabelled alcoholic moieties (Cl-Alkanol and CF3-Alkanol) was performed. Assuming that we got ready the acidic moiety, 3H-Ibuprofen, in our Laboratory, we attempted to label with tritium the alcoholic moiety and then go on to its esterification. Prior to labelling, thermic stability of 2-(4-(3-chlorophenyl)-1-piperazinyl) ethanol (Cl-Alkanol) was studied. As result of this study we had to change the labelling method, so that the Cl-Alkanol was unstable at 700C. Purification was accomplished through thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). Concentration, purity and specific activities of the two labelled compounds were determined by ultraviolet, HPLC and liquid scintillation techniques. (author)

    2012-01-01

    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.

  11. First class models from linear and nonlinear second class constraints

    Science.gov (United States)

    Dehghani, Mehdi; Mardaani, Maryam; Monemzadeh, Majid; Nejad, Salman Abarghouei

    2015-10-01

    Two models with linear and nonlinear second class constraints are considered and gauged by embedding in an extended phase space. These models are studied by considering a free non-relativistic particle on the hyperplane and hypersphere in the configuration space. The gauged theory of the first model is obtained by converting the very second class system to the first class one directly. In contrast, the first class system related to the free particle on the hypersphere is derived with the help of the infinite Batalin-Fradkin-Tyutin (BFT) embedding procedure. We propose a practical formula, based on the simplified BFT method, which is practical in gauging linear and some nonlinear second class systems. As a result of gauging these two models, we show that in the conversion of second class constraints to the first class ones, the minimum number of phase space degrees of freedom for both systems is a pair of phase space coordinates. This pair is made up of a coordinate and its conjugate momentum for the first model, but the corresponding Poisson structure of the embedded non-relativistic particle on hypersphere is a nontrivial one. We derive infinite correction terms for the Hamiltonian of the nonlinear constraints and an interacting gauged Hamiltonian is constructed by summing over them. At the end, we find an open algebra for three first class objects of the embedded nonlinear system.

  13. A New F-18 Labeled PET Agent For Imaging Alzheimer's Plaques

    International Nuclear Information System (INIS)

    Amyloid plaques and neurofibrillary tangles are hallmarks of Alzheimer's disease (AD). Advances in development of imaging agents have focused on targeting amyloid plaques. Notable success has been the development of C-11 labeled PIB (Pittsburgh Compound) and a number of studies have demonstrated the utility of this agent. However, the short half life of C-11 (t1/2: 20 min), is a limitation, thus has prompted the development of F-18 labeled agents. Most of these agents are derivatives of amyloid binding dyes; Congo red and Thioflavin. Some of these agents are in clinical trials with encouraging results. We have been exploring new class of agents based on 8-hydroxy quinoline, a weak metal chelator, targeting elevated levels of metals in plaques. Iodine-123 labeled clioquinol showed affinity for amyloid plaques however, it had limited brain uptake and was not successful in imaging in intact animals and humans. We have been successful in synthesizing F-18 labeled 8-hydroxy quinoline. Small animal PET/CT imaging studies with this agent showed high (7-10% ID/g), rapid brain uptake and fast washout of the agent from normal mice brains and delayed washout from transgenic Alzheimer's mice. These promising results encouraged us in further evaluation of this class of compounds for imaging AD plaques.

    2012-01-01

    We present an approach to labeling short video clips with English verbs as event descriptions. A key distinguishing aspect of this work is that it labels videos with verbs that describe the spatiotemporal interaction between event participants, humans and objects interacting with each other, abstracting away all object-class information and fine-grained image characteristics, and relying solely on the coarse-grained motion of the event participants. We apply our approach to a large set of 22 distinct verb classes and a corpus of 2,584 videos, yielding two surprising outcomes. First, a classification accuracy of greater than 70% on a 1-out-of-22 labeling task and greater than 85% on a variety of 1-out-of-10 subsets of this labeling task is independent of the choice of which of two different time-series classifiers we employ. Second, we achieve this level of accuracy using a highly impoverished intermediate representation consisting solely of the bounding boxes of one or two event participants as a function of ...

    A new method of feature extraction in the social network for within-network classification is proposed in the paper. The method provides new features calculated by combination of both: network structure information and class labels assigned to nodes. The influence of various features on classification performance has also been studied. The experiments on real-world data have shown that features created owing to the proposed method can lead to significant improvement of classification accuracy.

  5. A nucleotide-independent cyclic nitroxide label for monitoring segmental motions in nucleic acids

    International Nuclear Information System (INIS)

    Spin labels, which are chemically stable radicals attached at specific sites of a bio-molecule, enable investigations on structure and dynamics of proteins and nucleic acids using techniques such as site-directed spin labeling and paramagnetic NMR. Among spin labels developed, the class of rigid labels have limited or no independent motions between the radical bearing moiety and the target, and afford a number of advantages in measuring distances and monitoring local dynamics within the parent bio-molecule. However, a general method for attaching a rigid label to nucleic acids in a nucleotide-independent manner has not been reported. We developed an approach for installing a nearly rigid nitroxide spin label, designated as R5c, at a specific site of the nucleic acid backbone in a nucleotide-independent manner. The method uses a post-synthesis approach to covalently attach the nitroxide moiety in a cyclic fashion to phosphorothioate groups introduced at two consecutive nucleotides of the target strand. R5c-labeled nucleic acids are capable of pairing with their respective complementary strands, and the cyclic nature of R5c attachment significantly reduced independence motions of the label with respect to the parent duplex, although it may cause distortion of the local environment at the site of labeling. R5c yields enhanced sensitivity to the collective motions of the duplex, as demonstrated by its capability to reveal changes in collective motions of the substrate recognition duplex of the 120-kDa Tetrahymena group I ribozyme, which elude detection by a flexible label. The cyclic R5c nitroxide can be efficiently attached to a target nucleic acid site using a post-synthetic coupling approach conducted under mild biochemical conditions, and serves as a viable label for experimental investigation of segmental motions in nucleic acids, including large folded RNAs.

    We consider labeled Traveling Salesman Problems, defined upon a complete graph of n vertices with colored edges. The objective is to find a tour of maximum (or minimum) number of colors. We derive results regarding hardness of approximation, and analyze approximation algorithms for both versions of...... the problem. For the maximization version we give a -approximation algorithm and show that it is APX-hard. For the minimization version, we show that it is not approximable within n 1 − ε for every ε> 0. When every color appears in the graph at most r times and r is an increasing function of n the...... problem is not O(r 1 − ε )-approximable. For fixed constant r we analyze a polynomial-time (r + H r )/2-approximation algorithm (H r is the r-th harmonic number), and prove APX-hardness. Analysis of the studied algorithms is shown to be tight....

  7. ORGANIC FOOD LABELING AND CERTIFICATION

    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.

    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. PMID:6631228

    Chain restaurants will soon need to disclose calorie information on menus, but research on the impact of calorie labels on food choices is mixed. This study tested whether calorie information presented in different formats influenced calories ordered and perceived restaurant healthfulness. Participants in an online survey were randomly assigned to a menu with either (1) no calorie labels (No Calories); (2) calorie labels (Calories); (3) calorie labels ordered from low to high calories (Rank-Ordered Calories); or (4) calorie labels ordered from low to high calories that also had red/green circles indicating higher and lower calorie choices (Colored Calories). Participants ordered items for dinner, estimated calories ordered, and rated restaurant healthfulness. Participants in the Rank-Ordered Calories condition and those in the Colored Calories condition ordered fewer calories than the No Calories group. There was no significant difference in calories ordered between the Calories and No Calories groups. Participants in each calorie label condition were significantly more accurate in estimating calories ordered compared to the No Calories group. Those in the Colored Calories group perceived the restaurant as healthier. The results suggest that presenting calorie information in the modified Rank-Ordered or Colored Calories formats may increase menu labeling effectiveness. PMID:22918176

  2. Tritium labeling for bio-med research

    International Nuclear Information System (INIS)

    A very large fraction of what we know about biochemical pathways in the living cell has resulted from the use of radioactively-labeled tracer compounds; the use of tritium-labeled compounds has been particularly important. As research in biochemistry and biology has progressed the need has arisen to label compounds of higher specific activity and of increasing molecular complexity - for example, oligo-nucleotides, polypeptides, hormones, enzymes. Our laboratory has gradually developed special facilities for handling tritium at the kilocurie level. These facilities have already proven extremely valuable in producing labeled compounds that are not available from commercial sources. The principal ways employed for compound labeling are: (1) microwave discharge labeling, (2) catalytic tritio-hydrogenation, (3) catalytic exchange with T2O, and (4) replacement of halogen atoms by T. Studies have also been carried out on tritiation by the replacement of halogen atoms with T atoms. These results indicate that carrier-free tritium-labeled products, including biomacromolecules, can be produced in this way

  3. Unsupervised Identification of Isotope-Labeled Peptides.

    Goldford, Joshua E; Libourel, Igor G L

    2016-06-01

    In vivo isotopic labeling coupled with high-resolution proteomics is used to investigate primary metabolism in techniques such as stable isotope probing (protein-SIP) and peptide-based metabolic flux analysis (PMFA). Isotopic enrichment of carbon substrates and intracellular metabolism determine the distribution of isotopes within amino acids. The resulting amino acid mass distributions (AMDs) are convoluted into peptide mass distributions (PMDs) during protein synthesis. With no a priori knowledge on metabolic fluxes, the PMDs are therefore unknown. This complicates labeled peptide identification because prior knowledge on PMDs is used in all available peptide identification software. An automated framework for the identification and quantification of PMDs for nonuniformly labeled samples is therefore lacking. To unlock the potential of peptide labeling experiments for high-throughput flux analysis and other complex labeling experiments, an unsupervised peptide identification and quantification method was developed that uses discrete deconvolution of mass distributions of identified peptides to inform on the mass distributions of otherwise unidentifiable peptides. Uniformly (13)C-labeled Escherichia coli protein was used to test the developed feature reconstruction and deconvolution algorithms. The peptide identification was validated by comparing MS(2)-identified peptides to peptides identified from PMDs using unlabeled E. coli protein. Nonuniformly labeled Glycine max protein was used to demonstrate the technology on a representative sample suitable for flux analysis. Overall, automatic peptide identification and quantification were comparable or superior to manual extraction, enabling proteomics-based technology for high-throughput flux analysis studies.

    1991-02-22

    The D0 cryogenic control system is a complicated system with many facets. Because of the large number and variety of features in the system, a series of ongoing control system training seminars, or control classes, were created in order to keep people up to date on the operation of the system. As of the writing of this engineering note, there have been four classes. The original lecture notes from each class can be found in the cryogenic control room at the D0 Assembly Building, or in the Co-op office. This note provides a summary of the first three control classes, and it includes the entire set of notes from the fourth class, which was held in April of 1990. This class was taught by Jeff Wendlandt and Dan Markley. Dan should be consulted for more complete explanations than those given in the notes. The notes are, in fact, more of a reference for someone who has some experience with the system, than they are a training manual. Most of the pages include pictures and printouts of different menus and functions, useful for finding details without searching through the actual program. In general, this note serves as a pointer to the existence of the control class lecture notes, and as an explanation of their overall contents and purpose.

  5. First class models from linear and nonlinear second class constraints

    CERN Document Server

    Dehghani, Mehdi; Monemzadeh, Majid; Abarghooeinejad, Salman

    2014-01-01

    Two models with linear and nonlinear second class constraints are considered and gauged by embedding in an extended phase space. These models are the free non-relativistic particle on a hyperplane and hyper sphere in configuration space. For the first model we construct its gauged corresponding by the condition of converting second class system to first class one, directly. In contrast the first class system related to the free particle on hyper sphere is derived by the BFT embedding procedure, where its steps are infinite. We give a practical formula for gauging linear and some of the nonlinear second class systems, based on the simplified BFT method. As a result of the gauging two models, we show that in the conversion of second class to the first class constraints the minimum number of phase space degrees of freedom for both systems is a pair of phase space coordinate. This pair for first system is a coordinate and its momentum conjugate, but Poisson structure of embedded non-relativistic particle on hyper...

  6. Alternative methods of synthesizing 99Tcm-labelled ciprofloxacin

    International Nuclear Information System (INIS)

    Full text: 99Tcm-labelled ciprofloxacin (Infecton) is a new class of radiopharmaceutical designed for imaging live bacterial infection. We synthesized Infecton by modifying the procedure described by Keith Britton's group (Lancet 1996; 347: 233-235) and reported our findings at the ANZSNM meeting last year. Since the methodology was cumbersome, we investigated simpler alternative ways of labelling ciprofloxacin with 99Tcm-pertechnetate for routine imaging. There were several limitations in the previously described method: (1) Need to prepare pure ciprofloxacin which was unstable on storage. (2) Synthetic procedure using formimidine sulphinic acid (FSA) was complicated and required boiling step. (3) The radiochemical purity (RCP) of the product was low (45-50%) requiring purification. (4) Biodistribution studies showed a marked uptake by the liver which could interfere with scan interpretation in this region. The results of our present studies showed that Infecton could be prepared by a simple two-step method: (1) Reduce 99Tcm-pertechnetate with stannous salt (SnCl2 or Sn-tartrate). (2) Mix with Ciproxin IV-100. The RCP of the product was up to 98%, which obviates the need for further purification. Infecton synthesized by the above method showed avid localization in abscesses induced with Staphylococcus aureus in rats. The biodistribution studies showed that Infecton was renally excreted with minimal accumulation in the liver or other organs

    Objective: To explore the method of 99Tcm direct labeling of angiostatin (AS) and investigate the stability and bioactivity of the 99Tcm-labeled AS in vitro. Methods: AS was extracted, validated, and then labeled with 99Tcm after having been reduced by 2-ME or SnCl2. The best labeling condition was screened by cross design. The labeling efficiency was measured by TLC and column chromatography. The stability of 99Tcm-AS was observed and compared when BSA, saline and different molar ratios of Cys∶AS were separately added. The bioactivity of 99Tcm-AS was observed in human umbilical vein endothelial cell (CEV304). Results: The labeling efficiency can reach (97±1.5)% for the 2-ME-reducing approach. Its best experimental condition was as follows: AS 100 μg,PB(0.5 mol/L, pH 7.3)1 ml, 2-ME 100 μg, MDP (dissolved in 1 ml saline) 10 μl, and 99TcmO4- 185 MBq. The labeling efficiency using SnCl2-reducing method can reach (90±3.0)%. The best experimental procedure was as follows: AS 100 μg,boric acid buffer(0.1 mol/L, pH 9.0)1 ml, 2%SnCl2 (dissolved in 1 mol/L hydrochloric acid) 20 μl, was added into MDP, which was diluted with 1 ml deoxygenized water, and then 20 μl, 99TcmO4- 185 MBq was added. The product of 99Tcm labeled AS was stable in vitro and had the same bioactivity as AS. Conclusion: 99Tcm direct labeling of AS is simple and efficient. And the bioactivity of 99Tcm-AS has no significant change compared with AS.

  16. Vulnerability of exporting nations to the development of a carbon label in the United Kingdom

    International Nuclear Information System (INIS)

    Carbon labels inform consumers about the amount of greenhouse gases (GHGs) released during the production and consumption of goods, including food. In the future consumer and legislative responses to carbon labels may favour goods with lower emissions, and thereby change established supply chains. This may have unintended consequences. We present the carbon footprint of three horticultural goods of different origins supplied to the United Kingdom market: lettuce, broccoli and green beans. Analysis of these footprints enables the characterisation of three different classes of vulnerability which are related to: transport, national economy and supply chain specifics. There is no simple relationship between the characteristics of an exporting country and its vulnerability to the introduction of a carbon label. Geographically distant developing countries with a high level of substitutable exports to the UK are most vulnerable. However, many developing countries have low vulnerability as their main exports are tropical crops which would be hard to substitute with local produce. In the short term it is unlikely that consumers will respond to carbon labels in such a way that will have major impacts in the horticultural sector. Labels which require contractual reductions in GHG emissions may have greater impacts in the short term.

    Heterogeneity exists on a data set when samples from di erent classes are merged into the data set. Finite mixture models can be used to represent a survival time distribution on heterogeneous patient group by the proportions of each class and by the survival time distribution within each class as well. The heterogeneous data set cannot be explicitly decomposed to homogeneous subgroups unless all the samples are precisely labeled by their origin classes; such impossibility of decomposition is a barrier to overcome for estimating nite mixture models. The expectation-maximization (EM) algorithm has been used to obtain maximum likelihood estimates of nite mixture models by soft-decomposition of heterogeneous samples without labels for a subset or the entire set of data. In medical surveillance databases we can find partially labeled data, that is, while not completely unlabeled there is only imprecise information about class values. In this study we propose new EM algorithms that take advantages of using such partial labels, and thus incorporate more information than traditional EM algorithms. We particularly propose four variants of the EM algorithm named EM-OCML, EM-PCML, EM-HCML and EM-CPCML, each of which assumes a specific mechanism of missing class values. We conducted a simulation study on exponential survival trees with five classes and showed that the advantages of incorporating substantial amount of partially labeled data can be highly signi cant. We also showed model selection based on AIC values fairly works to select the best proposed algorithm on each specific data set. A case study on a real-world data set of gastric cancer provided by Surveillance, Epidemiology and End Results (SEER) program showed a superiority of EM-CPCML to not only the other proposed EM algorithms but also conventional supervised, unsupervised and semi-supervised learning algorithms.

    This paper introduces an on-line semi-supervised learning algorithm formulated as a regularized kernel spectral clustering (KSC) approach. We consider the case where new data arrive sequentially but only a small fraction of it is labeled. The available labeled data act as prototypes and help to improve the performance of the algorithm to estimate the labels of the unlabeled data points. We adopt a recently proposed multi-class semi-supervised KSC based algorithm (MSS-KSC) and make it applicable for on-line data clustering. Given a few user-labeled data points the initial model is learned and then the class membership of the remaining data points in the current and subsequent time instants are estimated and propagated in an on-line fashion. The update of the memberships is carried out mainly using the out-of-sample extension property of the model. Initially the algorithm is tested on computer-generated data sets, then we show that video segmentation can be cast as a semi-supervised learning problem. Furthermore we show how the tracking capabilities of the Kalman filter can be used to provide the labels of objects in motion and thus regularizing the solution obtained by the MSS-KSC algorithm. In the experiments, we demonstrate the performance of the proposed method on synthetic data sets and real-life videos where the clusters evolve in a smooth fashion over time. PMID:26319050

    @@ Implementing Outlines for the Chinese Environmental Labeling Program By awarding certificates and labels to related manufacturers in accordance with certain environmental labeling standards, environmental labeling,also called "Green Label"or "Eco-label", certifies via governmental departments or public and private organizations that the whole process of producing,using, recalling and disposing of manufacturers'products is in compliance with certain environmental requirements. Many countries are establishing and promoting environmental labeling plans. Environmental labeling, as an important promotion means for prevention and control of pollution in a market-oriented manner, is being extended and developed constantly across the world.

    Private labels have witnessed considerable growth in grocery retailing. While existing academic studies have provided valuable insights concerning the evolution of private labels, several issues remain largely unexplored. First, in the face of these large private-label volumes, private-label production opportunities arise. Due to increased private-label competition, national-brand manufacturers increasingly pursue a dual-branding strategy and engage in private-label production next to their n...

  8. Facile labeling of lipoglycans with quantum dots

    International Nuclear Information System (INIS)

    Bacterial endotoxins or lipopolysaccharides (LPS) are among the most potent activators of the innate immune system, yet mechanisms of their action and in particular the role of glycans remain elusive. Efficient non-invasive labeling strategies are necessary for studying interactions of LPS glycans with biological systems. Here we report a new method for labeling LPS and other lipoglycans with luminescent quantum dots. The labeling is achieved by partitioning of hydrophobic quantum dots into the core of various LPS aggregates without disturbing the native LPS structure. The biofunctionality of the LPS-Qdot conjugates is demonstrated by the labeling of mouse monocytes. This simple method should find broad applicability in studies concerned with visualization of LPS biodistribution and identification of LPS binding agents.

  9. Synthesis of tritium-labelled natural prostaglandins

    International Nuclear Information System (INIS)

    The most suitable method for the preparation of tritium-labelled prostaglandins is the biosynthetic procedure. Polyunsaturated labelled fatty acids are converted into prostaglandins by a prostaglandin synthetase enzyme system produced from sheep seminal vesicule, and the crude product is purified using thin layer chromatography. Polyunsaturated fatty acids are prepared in a reaction series. Tritium is introduced at the very last step. A very little amount (10-20 mg) of tritium-labelled prostaglandin E2 can be converted into A2, B2 and F2 respectively, conversion and separation being carried out simultaneously on the same silica plate. After the separation on thin layer silica gel the obtained tritium-labelled prostaglandin (PC) was chemically and radiochemically pure, its activity was 3700 GBq/mmol (100 Ci/mmol) and it was suitable for RIA kits.

  10. Generating Realistic Labelled, Weighted Random Graphs

    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...

  18. Radiobiological characteristic of tritium-labelled lysine

    International Nuclear Information System (INIS)

    Experiments on mice and rats injected with tritium-labeled lysine have revealed that one day after injection about 80% of the label was retained in organs and tissues as tissue-bound tritium. Retention curves for tritium in the body were decomposed into two exponentials. The biological half-lives of tritium-labeled lysine in various tissues exceed half-lives of other tritiated amino acids and of triated water. The average dose in different tissues following injection of tritiated lysine exceeds that from equal of tritium oxide (THO) by 1.5-8 times. Contribution of the tissue-bound tritium in dose is about 90%. radiobiological experiments showed strong genetic and citotoxic effects in male mice after injection of tritium-labeled lysine

    CERN Document Server

    2012-01-01

    Let C_1 and C_2 be strong amalgamation classes of finite structures, with disjoint finite signatures sigma and tau. Then C_1 wedge C_2 denotes the class of all finite (sigma cup tau)-structures whose sigma-reduct is from C_1 and whose tau-reduct is from C_2. We prove that when C_1 and C_2 are Ramsey, then C_1 wedge C_2 is also Ramsey. We also discuss variations of this statement, and give several examples of new Ramsey classes derived from those general results.

    Full Text Available It is quite frequent to copy and paste code fragments in software development. The copied source code is called a software clone and the activity is referred to as code cloning. The presence of code clones hamper maintenance and may lead to bug propagation. Now-a-days, model driven development has become a standard industry practice. Duplicate parts in models i.e. model clones pose similar challenges as in source code. This paper presents an approach to detect clones in Unified Modeling Language class models. The core of our technique is the construction of a labeled, ranked tree corresponding to the UML class model where attributes with their data types and methods with their signatures are represented as subtrees. By grouping and clustering of repeating subtrees, the tool is able to detect duplications in a UML class model at different levels of granularity i.e. complete class diagram, attributes with their data types and methods with their signatures across the model and cluster of such attributes/methods. We propose a new classification of model clones with the objective of detecting exact and meaningful clones. Empirical evaluation of the tool using open source reverse engineered and forward designed models show some interesting and relevant clones which provide useful insights into software modeling practice.

  7. Stability of rhenium-188 labeled antibody

    International Nuclear Information System (INIS)

    For clinical application of beta-emitter labeled antibody, high specific activity is important. Carrier-free Re-188 from W-188/Re-188 generator is an ideal radionuclide for this purpose. However, low stability of Re-188 labeled antibody, especially in high specific activity, due to radiolytic decomposition by high energy (2.1 MeV) beta ray was problem. We studied the stability of Re-188 labeled antibody, and stabilizing effect of several nontoxic radical-quenching agents. Pre-reduced monoclonal antibody (CEA79.4) was labeled with Re-188 by incubating with generator-eluted Re-188-perrhenate in the presence of stannous tartrate for 2 hr at room temperature. Radiochemical purity of each preparation was determined by chromatography (ITLC-SG/acetone, ITLC-SG/Umezawa, Whatman No.1/saline). Human serum albumin was added to the labeled antibodies(2%). Stability of Re-188-CEA79.4 was investigated in the presence of vitamin C, ethanol, or Tween 80 as radical-quenching agents. Specific activities of 4.29∼5.11 MBq/μg were obtained. Labeling efficiencies were 88±4%(n=12). Very low stability after removal of stannous tartrate from the preparation was observed. If stored after purging with N2, all the preparations were stable for 10 hr. However, if contacted with air, stability decreased. Perrhenate and Re-188-tartrate was major impurity in declined preparation (12∼47 and 9∼38% each, after 10 hr). Colloid-formation was not a significant problem in all cases. Addition of vitamin C stabilized the labeled antibodies either under N2 or under air by reducing the formation of perrhenate. High specific activity Re-188 labeled antibody is unstable, especially, in the presence of oxygen. Addition of vitamin C increased the stability

    2015-12-01

    The traditional classification approaches use labeled training data to select the best classification model from a family of models. Since collecting labeled samples is often tedious and sometimes even infeasible, recent research in machine learning has focused on developing algorithms to train classification models in scarcity of labeled training samples. In contrast, the focus of our research is to address problem settings where acquiring even a small number of expert-annotated labeled samples for supervision is infeasible. I will present RAPT, a new predictive modeling framework for identifying rare classes when there is a complete absence of labeled data. The RAPT framework is designed to use imperfectly annotated training data to learn classification models in the absence of expert-annotated training samples. Our results show that, under some reasonable assumptions, the classifiers trained from imperfectly labeled training data using the RAPT approach have performance comparable to the classification models trained using expert-annotated training data. This capability of learning from imperfect supervision is advantageous in a wide range of applications where the target class of interest is relatively rare and obtaining a precise labeling of even a small number of training samples is infeasible. I will also present the application of the RAPT framework for creating historical maps of forest fires from satellite data for the tropical forests. This new forest fire product identifies approximately 1 million sq. km. of burned areas in the tropical forests in South America and South-east Asia during years 2001-2014, which is more than three times the total burned area reported by the state-of-art NASA products. We show validation of these results using burn-scars visible in satellite images, including high resolution Landsat images, to confirm the veracity of the previously unreported forest fires.

    Freed, Rachel D; Tompson, Martha C; Otto, Michael W; Nierenberg, Andrew A; Henin, Aude

    2015-12-15

    Bipolar disorder (BD) is highly heterogeneous, and course variations are associated with patient outcomes. This diagnostic complexity challenges identification of patients in greatest need of intervention. Additionally, course variations have implications for offspring risk. First, latent class analysis (LCA) categorized parents with BD based on salient illness characteristics: BD type, onset age, polarity of index episode, pole of majority of episodes, rapid cycling, psychosis, anxiety comorbidity, and substance dependence. Fit indices favored three parental classes with some substantively meaningful patterns. Two classes, labeled "Earlier-Onset Bipolar-I" (EO-I) and "Earlier-Onset Bipolar-II" (EO-II), comprised parents who had a mean onset age in mid-adolescence, with EO-I primarily BD-I parents and EO-II entirely BD-II parents. The third class, labeled "Later-Onset BD" (LO) had an average onset age in adulthood. Classes also varied on probability of anxiety comorbidity, substance dependence, psychosis, rapid cycling, and pole of majority of episodes. Second, we examined rates of disorders in offspring (ages 4-33, Mage=13.46) based on parental latent class membership. Differences emerged for offspring anxiety disorders only such that offspring of EO-I and EO-II parents had higher rates, compared to offspring of LO parents, particularly for daughters. Findings may enhance understanding of BD and its nosology. PMID:26394919

  14. Thrombokinetics with In-111-oxine labelled platelets

    International Nuclear Information System (INIS)

    Indium-111-oxine has been employed as a redioactive platelet label for thrombosis imaging and thrombokinetic studies in man. To evaluate it's suitability for platelet survival and turnover, thrombokinetic studies were carried out in hematological normal subjects, in patients with idiopathic thrombocytopenic purpura (ITP) and chronic congestive splenomegaly. For In-111-oxine labelled platelets, platelets were collected by differential centrifugation from 44 ml of whole blood drawn into 6 ml of acid citrate dextrose solution. Platelet suspension was incubated with In-111-oxine, which was extracted before use by the method of Thakur and co-workers. The survival, recovery and turnover of In-111-labeled platelets were 8.6 +- 0.5 days, 63.0 +- 5.4% and 3.9 +- 0.3 x 104/ μl/day, respectively, which were similar with those of Cr-51 method. Platelet disappearance curves labelled with In-111 and Cr-51 simultaneously were similar in one case. In patients with ITP, platelet survival shortened in the same degree with Cr-51 method. The two simultaneous labeling studies between In-111 and Cr-51 showed no differences. In the patients with congestive splenomegaly, the same results were obtained. Thrombokinetic studies with In-111-oxine labelled platelets offer the advantages of reduced blood requirements, and the ability to perform external imaging of platelet distribution. (author)

    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. PMID:23093951

  16. Weed Seed Labelling with Rare Earth Elements

    International Nuclear Information System (INIS)

    The dormancy period of weed seed under field conditions so far could not be determined with reliability because of the lack of a suitable method for labelling seed. Rademacher and co-workers labelled weed seed with 35S for studying germination in relation to different methods of soil cultivation. Since 35S has a half-period of 87.1 d only, labelling is practically ineffective after one year. The authors of this paper therefore tried to label weed seed with lanthanum, europium and dysprosium. Since these elements (1) do not occur in the standard soils in interfering quantities, and (2) can easily be determined by neutron activation analysis, they are useful for non-radioactive labelling. In pot experiments they were added like fertilizers before the soil was seeded with Sinapsis alba or Vicia villosa. After harvesting, samples of the plants' roots, stems, leaves, and seed were irradiated in the reactor and the rare earth elements determined by neutron-activation analysis. Evaluation of the results disclosed that traceable quantities of lanthanum, europium, and dysprosium were present in roots, stems, and leaves, but not in the grains of seed. It is the intention, in further experiments, to increase the concentration of the applied elements up to the limit of compatibility, and to find out whether a more concentrated supply will increase the incorporation in seeds. If one of these elements is present in a reasonable concentration, experiments with labelled weed seed will be possible for periods of several years. (author)

    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.

    Full Text Available In the intensive competitive environment, retailers incline to develop their own branded products (private label products to make a differentiation over their rivals and to gain a market share. On the other side, retailers’ have some objectives in developing private label products. At this point, this study put forwards the differences between retailers’ some characteristics and objectives of developing private label products and investigates the tendencies and expectations towards private label products. The results of the research present that there are no differences in the objectives of developing private label products according to the food retailers’ ownership of private label. However, it is found that there are some differences in the objectives of developing private label products according to the food retailers’ level of activity, number of branches and scale. In the study, it is also put forward that food retailers expect an increase in the demand of private label products at nearly terms and inclining to develop private labels more than before.

  19. Second class currents and nuclei

    International Nuclear Information System (INIS)

    A theoretical analysis of the recent experimental data relevant to second-class currents is made on the basis of the effective two-body operator approach proposed several years ago by the present authors. It takes into account nuclear many-body effects such as off-the-energy-shell and meson-exchange effects. The previous results indicating the presence of second-class currents comparable in their magnitudes to the weak magnetism term are altered. Next, we suggest that mesonic effects on the time-component of first-class axial current can be tested unambiguously. The argument is based on the low-energy theorem and model-independent to great degree. We emphasize that further correlation experiments are highly desirable not only for testing the second-class currents but also making a clean test of the mesonic effects on axial current. (author)

    Typically, introductory physics courses are taught with a combination of lectures and laboratories in which students have opportunities to discover the natural laws through hands-on activities in small groups. This article reports the use of Google Drive, a free online document-sharing tool, in physics laboratories for pooling experimental data from the whole class. This pedagogical method was reported earlier, and the present article offers a few more examples of such "whole class" laboratories.

  3. Internet service classes under competition

    2000-01-01

    This paper analyzes competition between two Internet service providers (ISPs), either or both of which may choose to offer multiple service classes. In the model analyzed, a social planner who maximizes the total benefit from network usage and a profit maximizing monopolist will both form multiple service classes; but two networks competing to maximize profits will not. The reason is that a competition effect always outweighs a segmentation effect. Networks wish to offer multiple service clas...

  5. Rhenium 188 labelling of peptide conjugates

    2001-07-01

    Many human tumours express high levels, of somatostatin receptors. In order to make possible a radiotherapeutic treatment of this kind for tumour a series of somatostatin analogues that can tightly chelate beta emitting isotopes have been developed in recent years. The work carried out for this thesis has been aimed towards development of a new therapeutic radiopharmaceutical for treatment of somatostatin receptor positive tumours. The first chapters describe work with technetium-99m to establish the labelling and analytical conditions for a somatostatin analogue, [Tyr{sup 3}]-octreotide (TOC), as a precursor to undertaking labelling studies with the beta emitter rhenium-188. 6-Hydrazinopyridine-3-carboxylic acid (HYNIC) was conjugated to TOC and labelled with {sup 99m} using different coligands. Then the stability, receptor binding and biodistribution of each complex were assessed. {sup 99m}Tc-HYNIC-TOC using EDDA as coligand showed the best characteristics, and was superior for tumour imaging in humans than the commercially available {sup 111}In-DTPA-octreotide. The conditions for labelling the HYNIC-TOC conjugate with {sup 188}Re were then optimised using tricine as a co-ligand. A labelling yield of {approx}80% was achieved. After purification however, the stability of the complex was low. The use of other coligand systems which had proved useful for {sup 99m}Tc labelling was explored, but yields were very poor. Other chelators such as diethylenetriamine pentaacetic acid (DTPA), dimercaptosuccinic acid (DMSA) and mercaptoacetyltriglycine (MAG{sub 3}) were studied as potential co-ligand agents to label the HYNIC-TOC conjugate with {sup 188}Re but, again low yields of the labelled peptide complexes were achieved. A novel {sup 188}Re-HYNIC complex was prepared in high yields using N-N-disubstituted dithiocarbamates as coligands. However to date, the specific activities achieved with this system are relatively low. The use of the [{sup 99m}Tc(CO){sub 3}(H{sub 2}O

    Full Text Available O artigo procura resgatar, no pensamento de Antonio Gramsci, a concepção de classes subalternas e a sua relação com outras categorias, especialmente, o Estado, a sociedade civil e a hegemonia, como suportes da luta de classes na realidade contemporânea. Aborda, ainda, as relações entre classes subalternas, senso comum e ideologia, bem como as formas de superação tematizadas por Gramsci, através da cultura e da filosofia da práxis. Nesse sentido, num movimento de totalidade, busca recuperar a discussão das classes subalternas, a partir da original formulação gramsciana no âmbito do marxismo, mediante a interação dialética entre estrutura e superestrutura, economia e política. Além do resgate conceitual, apontam-se alguns elementos como subsídios à discussão das formas de subalternidade presentes na realidade contemporânea e as possibilidades de fortalecimento das lutas de tais camadas de classe, sobretudo em momentos de forte desmobilização da participação popular.This article sought to revive the concept of subaltern classes and their relation with other categories, particularly the State, civil society and hegemony in the thinking of Antonio Gramsci, as a support for contemporary class struggles. It also analyzes the relations between subaltern classes, common sense and ideology, as well as the forms of "overcoming" conceptualized by Gramsci, through the culture and philosophy of praxis. The paper revives the discussion of the subaltern classes, based on the original Gramscian formulation in the realm of Marxism, through the dialectic interaction between structure and superstructure, economy and politics. In addition to the conceptual revival, it indicates some elements that can support the discussion of the forms of subalternity found in contemporary reality and the possibilities for strengthening the struggles of these class layers, above all in moments of strong demobilization of popular participation.
