  6. Policy Perspectives on OTC Derivatives Market Infrastructure

    Darrell DUFFIE; Li, Ada; Lubke, Theo


    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...

  10. [Development of an Informative System for Consumers and Pharmacists Aimed at the Proper Use of Kampo OTCs].

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


    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

  15. OTC tamsulosin for benign prostatic hyperplasia.


    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

    Sunil Mathur


    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

    De Ferrari Luna


    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.

    Nishizawa, Motohito


    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.

  2. The OTC derivatives markets after financial reforms

    Amariei, Cosmina; Valiante, Diego


    Over the past five years, the OTC derivatives market showed an impressive resilience in levels of market activity, which are now above pre-crisis levels in outstanding notional value. This confirms its systemic importance. Current volatility of the gross market values and gross credit exposures can be attributed to the uncertain market conditions for the global economy. Distribution of derivatives instruments has remained relatively constant over the past decade. Central clearing and portfoli...

  3. Mitigating systemic risk in OTC derivative markets.

    Wellink, N.


    The financial crisis has demonstrated that turmoil in OTC derivative markets can exacerbate financial distress. One of the challenges policymakers currently face, is to mitigate the risks these markets pose to the financial system. Inducing a shift towards more central clearing is an important step in the right direction as it tempers counterparty risk and increases transparency. However, this will only be part of the solution as risk management systems of Central Counterparties (CCPs) are no...

  4. Derivative Market Competition: OTC Versus Organized Derivative Exchanges

    Jens Nystedt


    Recent regulatory initiatives in the United States have again raised the issue of a 'level regulatory and supervisory playing field' and the degree of competition globally between over-the-counter (OTC) derivatives and organized derivative exchange (ODE) markets. This paper models some important aspects of how an ODE market interrelates with the OTC markets. It analyzes various ways in which an ODE market can respond to competition from the OTC markets and considers whether ODE markets would ...

  5. An investigative model evaluating how consumers process pictorial information on nonprescription medication labels.

    Sansgiry, S S; Cady, P S


    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

  6. Atherosclerotic plaque component segmentation in combined carotid MRI and CTA data incorporating class label uncertainty.

    van Engelen, Arna; Niessen, Wiro J; Klein, Stefan; Groen, Harald C; Verhagen, Hence J M; Wentzel, Jolanda J; van der Lugt, Aad; de Bruijne, Marleen


    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.

  7. A New Class of 99mTc(I) Agents for SLND: Labelling and Quality Control. Chapter 6

    In an attempt to prepare a new class of tracers for SLND, the radiolabelling of mannosylated dextran derivatives containing the tridentate pz diamine and cysteine chelators for stabilization of the organometallic core fac-[99mTc(CO)3]+ are reported. This chapter demonstrates the optimization of the labelling conditions to achieve high radiochemical purity and specific activity. These results are of paramount importance for the biological properties of the compounds, namely their mannose receptor targeting properties. (author)

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

    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

  9. Competition-based cellular peptide binding assays for 13 prevalent HLA class I alleles using fluorescein-labeled synthetic peptides.

    Kessler, Jan H; Mommaas, Bregje; Mutis, Tuna; Huijbers, Ivo; Vissers, Debby; Benckhuijsen, Willemien E; Schreuder, Geziena M Th; Offringa, Rienk; Goulmy, Els; Melief, Cornelis J M; van der Burg, Sjoerd H; Drijfhout, Jan W


    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.

    At present there is sizable activity in the OTC derivatives market that is under-collateralised. The margin/collateral requirements at central counterparties (CCPs) should help the OTC derivatives market be better collateralised, lowering the derivatives risk at the large banks that dominate this market. However, the overall netting benefits may be less if the several CCPs that are in operation are not linked. Also, large banks make very effective use of collateral they receive that has rehyp...

    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.

  17. Consumer involvement: effects on information processing from over-the-counter medication labels.

    Sansgiry, S S; Cady, P S; Sansgiry, S


    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

    Antonio Nicolo’; Loriana Pelizzon


    How does bank capital regulation affect the design of credit derivative contracts? How does the opacity of the OTC credit derivative markets affect these contracts? In this paper we address these issues and characterize the optimal security design in several settings. We show that both the level of the banks' cost of capital and the opacity of the credit derivative markets do affect the form of the optimal separating contract and the level of the banks' profits. Moreover, our results suggest ...

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.

    Nanumyan, Vahan; Garas, Antonios; Schweitzer, Frank


    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

    Ross Friedman, C M; Ross, B N; Martens, G D


    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.

  6. Estimation of hospital emergency room data using otc pharmaceutical sales and least mean square filters

    Magruder SF


    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.

  8. Microcantilevers and organic transistors: two promising classes of label-free biosensing devices which can be integrated in electronic circuits.

    Cotrone, Serafina; Cafagna, Damiana; Cometa, Stefania; De Giglio, Elvira; Magliulo, Maria; Torsi, Luisa; Sabbatini, Luigia


    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.

  13. Whole Xp Deletion in a Girl with Mental Retardation, Epilepsy, and Biochemical Features of OTC Deficiency

    Joost, K.; Tammur, P.; Teek, R.; Žilina, O.; Peters, M; Kreile, M.; Lace, B.; Žordania, R.; Talvik, I.; Õunap, K.


    Background: Females with a total or partial deletion of the short arm of the X chromosome have variable features of Turner syndrome, but mental retardation (MR) rarely occurs. The haploinsufficiency of deleted genes that escape X-inactivation may explain the occurrence of MR and autism. Ornithine transcarbamylase (OTC) deficiency is the most common urea cycle disorder and is inherited in an X-linked semi-dominant trait, and the OTC gene maps to Xp21. Methods: We report on a girl with MR, epil...

  14. Toxicity of OTC to Ipomoea aquatica Forsk. and to microorganisms in a long-term sewage-irrigated farmland soil.

    Ma, Tingting; Chen, Li'ke; Wu, Longhua; Christie, Peter; Luo, Yongming


    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

  17. Flower evolution of alpine forbs in the open top chambers (OTCs) from the Qinghai-Tibet Plateau.

    Zhang, Chan; Wang, Lin-Lin; Yang, Yong-Ping; Duan, Yuan-Wen


    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

  8. Head lice surveillance on a deregulated OTC-sales market: a study using web query data.

    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

    Shweta C. Dharmadhikari


    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.

  14. The practice of OTC counseling by community pharmacists in Parana, Brazil

    Halila GC


    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

    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

    Merger Eduard


    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

    Mahenc, Philippe


    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. Abuse of "BRON": a Japanese OTC cough suppressant solution containing methylephedrine, codeine, caffeine and chlorpheniramine.

    Ishigooka, J; Yoshida, Y; Murasaki, M


    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

  2. Nutrition Labeling

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

  5. A survey study on use of over the counter (OTC drugs among medical students, nursing and clerical staff of a tertiary care teaching rural hospital

    Devang Parikh


    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.

  6. pH induced polychromatic UV treatment for the removal of a mixture of SMX, OTC and CIP from water

    Avisar, D., E-mail: [Hydro-chemistry Laboratory, Geography and the Environment, Tel Aviv University, Tel Aviv 69978 (Israel); Lester, Y. [Hydro-chemistry Laboratory, Geography and the Environment, Tel Aviv University, Tel Aviv 69978 (Israel); School of Mechanical Engineering, Faculty of Engineering, Tel Aviv University, Tel Aviv 69978 (Israel); Mamane, H. [School of Mechanical Engineering, Faculty of Engineering, Tel Aviv University, Tel Aviv 69978 (Israel)


    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

    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

    Wu, Baoyuan


    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 define a notion of complexity for labeled oriented trees (LOTs) related to the bridge number in knot theory and prove that LOTs of complexity 2 are aspherical. We also present a class of LOTs of higher complexity which is aspherical, give an upper bound for the complexity of labeled oriented intervals and study the complexity of torus knots.

  12. Food labels

    Selsøe Sørensen, Henrik; Clement, Jesper; Gabrielsen, Gorm


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

  14. theories of class

    Gaiotto, Davide; Razamat, Shlomo S.


    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

    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

    A healthy equity valuation system will promote the long-term development of the OTC market, and will provide more national and transparent financing channels for those small and medium-sized enterprises. The stock valuation methods used in the OTC market of North America are based on those methods used in the main board markets. In practice, some adjustments are necessary and important. For those small and medium-sized enterprises in China, the stock valuation methods are determined by the characteristics of business. The stock value is inextricably bound to the trend of earnings. The combination of several valuation methods is necessary. It’s better to avoid too many assumptions and complex process.

  17. Asymptotic study of subcritical graph classes

    Drmota, Michael; Kang, Mihyun; Kraus, Veronika; Rué, Juanjo


    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

    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.

    Rana, Gianfranco; Katerji, Nader; Mastrorilli, Marcello


    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.


    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.

  7. Succesful labelling schemes

    Juhl, Hans Jørn; Stacey, Julia


    It is usual practice to evaluate the success of a labelling scheme by looking at the awareness percentage, but in many cases this is not sufficient. The awareness percentage gives no indication of which of the consumer segments that are aware of and use labelling schemes and which do not. In the...... spring of 2001 MAPP carried out an extensive consumer study with special emphasis on the Nordic environmentally friendly label 'the swan'. The purpose was to find out how much consumers actually know and use various labelling schemes. 869 households were contacted and asked to fill in a questionnaire....... 664 households returned a completed questionnaire. There were five answering categories for each label in the questionnaire: * have not seen the label before. * I have seen the label before but I do not know the precise contents of the labelling scheme. * I have seen the label before, I do not know...

  18. Interval prediction for graded multi-label classification

    Lastra, Gerardo; Bahamonde, Antonio


    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

    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

    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

    Li, Yongqiang


    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

    Nicolas Robitaille


    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.

  11. OR Specimen Labeling.

    Zervakis Brent, Mary Ann


    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?

    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.

  20. Like your labels?

    Field, Michele


    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

  1. Certified Rule Labeling

    Nagele, Julian; Zankl, Harald


    The rule labeling heuristic aims to establish confluence of (left-)linear term rewrite systems via decreasing diagrams. We present a formalization of a confluence criterion based on the interplay of relative termination and the rule labeling in the theorem prover Isabelle. Moreover, we report on the integration of this result into the certifier CeTA, facilitating the checking of confluence certificates based on decreasing diagrams for the first time. The power of the method is illustrated by ...

  2. Labelling of Vincamine derivatives

    Tritium labelled Vincamine and ethyl apovincaminate (Cavinton) have been prepared on the bases of known stereospecific synthesis. High specific activity compounds were obtained by the catalytic tritiation of appropriate unsaturated starting compounds. When the structure of the unsaturated starting compounds was changed (even rather for from the reaction centre) instead of the catalytic addition of tritium a specific hydrogen-tritium exchange reaction was found to be the main labelling process

  3. Labelling of electricity

    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

  4. Evaluation of Community Pharmacists Performance in Management of Cough, Diarrhea and Common Cold using OTC Medication Requests in Hamadan in 2015

    A. Rashidi


    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.

  5. Streaming Label Learning for Modeling Labels on the Fly

    You, Shan; Xu, Chang; Wang, Yunhe; Xu, Chao; Tao, Dacheng


    It is challenging to handle a large volume of labels in multi-label learning. However, existing approaches explicitly or implicitly assume that all the labels in the learning process are given, which could be easily violated in changing environments. In this paper, we define and study streaming label learning (SLL), i.e., labels are arrived on the fly, to model newly arrived labels with the help of the knowledge learned from past labels. The core of SLL is to explore and exploit the relations...

    This paper suggests a modelling of the labelling procedure consistent with empirical observations, that allows the endogenous calculation of labelling criteria. The authority in charge of the labelling program chooses the level of labelling criteria so as to maximise the social surplus, anticipating competition between firms in environmental qualities and prices. While accounting simply for the informational role of labels, this model allows to understand observed behavior such as firms' igno...

  11. Radio labeling with preassigned frequencies.


    A radio labeling of a graph G is an assignment of pairwise distinct, positive integer labels to the vertices of G such that labels of adjacent vertices differ by at least $2$. The radio labeling problem (RL) consists in determining a radio labeling that minimizes the maximum label that is used (the so-called span of the labeling). RL is a well-studied problem, mainly motivated by frequency assignment problems in which transmitters are not allowed to operate on the same frequency channel. We c...

  12. Radioactive labelling of peptidic hormones

    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.

    Zhao, Ruiqi; Martinez, Aleix M


    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

  14. Synthesis of labeled compounds

    Intermediate compounds labeled with 13C included methane, sodium cyanide, methanol, ethanol, and acetonitrile. 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

  15. Fluorine-18 labelled compounds

    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.)

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

  19. Radioactively labelled porphyrin derivatives

    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. Neither UV-Vis spectrometry nor TLC gave evidence of any incorporation of the ReO4- anion into the porphyrin ring

  10. Labeling 3D scenes for Personal Assistant Robots

    Koppula, Hema Swetha; Joachims, Thorsten; Saxena, Ashutosh


    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...

  16. Nomenclature for labelled compounds

    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

    Zhang, Meng; Tang, Jijun


    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.

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


    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)

    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.

  5. Loosely coupled class families

    Ernst, Erik


    Families of mutually dependent classes that may be accessed polymor- phically provide an advanced tool for separation of concerns, in that it enables client code to use a group of instances of related classes safely without depending on the exact classes involved. However, class families which are...... expressed using virtual classes seem to be very tightly coupled internally. While clients have achieved the freedom to dynamically use one or the other family, it seems that any given family contains a xed set of classes and we will need to create an entire family of its own just in order to replace one of...... the members with another class. This paper shows how to express class families in such a manner that the classes in these families can be used in many dierent combinations, still enabling family polymorphism and ensuring type safety....

  6. Waisda?: video labeling game

    Hildebrand, Michiel; Brinkerink, M.; Gligorov, R.; Steenbergen, Van; Huijkman, J.; Oomen, J.


    The Waisda? video labeling game is a crowsourcing tool to collect user-generated metadata for video clips. It follows the paradigm of games-with-a-purpose, where two or more users play against each other by entering tags that describe the content of the video. Players score points by entering the same tags as one of the other players. As a result each video that is played in the game is annotated with tags that are anchored to a time point in the video. Waisda? has been deployed in two projec...

    Convolutional Neural Network (CNN) has demonstrated promising performance in single-label image classification tasks. However, how CNN best copes with multi-label images still remains an open problem, mainly due to the complex underlying object layouts and insufficient multi-label training images. In this work, we propose a flexible deep CNN infrastructure, called Hypotheses-CNN-Pooling (HCP), where an arbitrary number of object segment hypotheses are taken as the inputs, then a shared CNN is...

  12. Label and Label-Free Detection Techniques for Protein Microarrays

    Amir Syahir


    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.

  14. Edge colouring by total labellings

    Brandt, Stephan; Rautenbach, D.; Stiebitz, M.;


    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.

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


    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

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


    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.

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


    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. Promising results for text-based image retrieval on the NUS-WIDE dataset as well as news classification and text categorization on several real-world multi

  20. Multi-dimensional classification with super-classes

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


    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

    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

    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

    Varma, Manoj M


    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

    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

    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.

We further provide a general characterization of the magnitudes of these improvements in terms of a novel generalization of the disagreement coeff...

  17. Incorporation of 3H-labeled nucleosides and 3H-labeled deoxynucleosides into detergent soluble DNA

    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

  19. Class network routing

    Bhanot, Gyan; Blumrich, Matthias A.; Chen, Dong; Coteus, Paul W.; Gara, Alan G.; Giampapa, Mark E.; Heidelberger, Philip; Steinmacher-Burow, Burkhard D.; Takken, Todd E.; Vranas, Pavlos M.


    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.

    Khare, Ritu; Li, Jiao; Lu, Zhiyong


    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

    Sabato, Sivan


    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...

  16. Crowd & Prejudice: An Impossibility Theorem for Crowd Labelling without a Gold Standard

    Della Penna, Nicolás; Reid, Mark D.


    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

    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

  20. Radio labeling with pre-assigned frequencies

    Bodlaender, H.L.; Broersma, H.J.; Fomin, F.V.; Pyatkin, A.V.; Woeginer, G.J.


    A radio labeling of a graph G is an assignment of pairwise distinct, positive integer labels to the vertices of G such that labels of adjacent vertices differ by at least 2. The radio labeling problem (RL) consists in determining a radio labeling that minimizes the maximum label that is used (the so-called span of the labeling). RL is a well-studied problem, mainly motivated by frequency assignment problems in which transmitters are not allowed to operate on the same frequency channel. We con...

  7. Embodying class and gender

    Geers, Alexie


    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...

  9. Photoaffinity Labeling of Plasma Proteins

    Masaki Otagiri


    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

    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
