Peres-Horodecki Separability Criterion for Continuous Variable Systems
No full textThe Peres-Horodecki criterion of positivity under partial transpose is studied in the context of separability of bipartite continuous variable states. The partial transpose operation admits, in the continuous case, a geometric interpretation as mirror reflection in phase space. This recognition leads to uncertainty principles, stronger than the traditional ones, to be obeyed by all separable states. For all bipartite Gaussian states, the Peres-Horodecki criterion turns out to be a necessary and sufficient condition for separability
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Tooth loss is associated with increased blood pressure in adults - a multidisciplinary population-based study
No full textObjectivesTo investigate whether tooth loss is associated with increased blood pressure among adults after controlling for socioeconomic, health, and lifestyle confounders. We also assessed the interactions between tooth loss and smoking status and tooth loss and age on systolic blood pressure (SBP).Material and methodsA population-based cross-sectional study was carried out with 1720 adults from Florianópolis, Brazil. Data collection included blood pressure, anthropometric measures, and a questionnaire on socio-demographics, self-rated health, diabetes, self-reported number of natural teeth, and dental prosthesis. We used linear multivariable regression models for the association of blood pressure with tooth loss adjusting for potential confounders.ResultsEdentulous subjects had a SBP 8.3 mmHg (95% CI 0.1; 16.7) higher than those with more than 10 teeth in both arches after adjustment for potential confounders. We found interaction between tooth loss and smoking status. Moderate/heavy smokers were associated with considerably higher SBP than light, former or non-smokers among edentulous and also partly among dentate with less than 10 teeth in at least one arch, but there was no real association between smoking and SBP among those with 10 or more teeth in both arches.ConclusionsTotal tooth loss is associated with increased levels of SBP in this adult population.Marco A.

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
PEMBERIAN ENZIM PAPAIN DALAM PAKAN TERHADAP GAMBARAN HISTOLOGI USUS BENIH IKAN PERES (OSTEOCHILLUS KAPPENI)
No full textABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh pemberian enzim papain dalam pakan terhadap gambaran histologi usus benih ikan peres. Penelitian ini dilaksanakan pada bulan September hingga bulan Oktober 2015 yang bertempat di Balai Benih Ikan (BBI) Lukup Badak, Aceh Tengah dan Laboratorium Histologi Fakultas Kedokteran Hewan Universitas Syiah Kuala. Metode yang digunakan dalam penelitian ini adalah metode eksperimental menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Perlakuan dalam penelitian berupa pemberian enzim papain dengan konsentrasi yang berbeda. Hasil penelitian menunjukkan bahwa penambahan dosis papain yang berlebihan dalam pakan ikan peres akan membuat makanan akan lebih lama mengalami proses pencernaan, sehingga berpengaruh terhadap proses penyerapan makanan. Hal ini terlihat pada perubahan ukuran vili usus ikan peres. Dampak pemberian enzim papain optimum 2% dibuktikan dengan gambaran histologi yang menunjukkan kinerja organ yang efektif.Kata Kunci: Ikan peres, enzim papain, histologi usus, kualitas air
Lma Parameters And Non-zero Ue3 Effects On Atmospheric ν Data?

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Association between black stains and dental caries in primary teeth: findings from a Brazilian population-based birth cohort
No full textLower dental caries experience has been observed in children and teenagers with the presence of black stains on dental structures. However, none of the previous investigations were population-based studies or adjusted the analysis for potential confounders. This study assessed the prevalence of black stains at the age of 5 in a population-based birth cohort from Pelotas, Brazil and investigated the association between black stains and dental caries. A total of 1,129 children from the 2004 Pelotas birth cohort were examined at age 5, and their mothers were interviewed at their households. Dental examinations included a search for black stains and dental caries on the primary dentition through the dmf-s index. The mothers’ questionnaire comprised data on demographic, social, and behavior aspects. Prevalence of black stains was 3.5% (95% CI 2.5–4.7) and the prevalence of dental caries was 48.4% (95% CI 45.4–51.4). Multivariable logistic regression analysis was performed to assess the association between black stains and dental caries. Adjusted analysis revealed that the presence of black stains was associated with lower levels of dental caries (OR = 0.51; 95% CI 0.26–0.99). The results of the present study suggest that black stains are a protective factor for dental caries development.C. C. França-Pinto, M. S. Cenci, M. B. Correa, A. R. Romano, M. A. Peres, K. G.

Noiseless method for checking the Peres separability criterion by local operations and classical communication
No full textWe present a method for checking the Peres separability criterion in an arbitrary bipartite quantum state rho(AB) within local operations and classical communication scenario. The method does not require noise operation which is needed in making the partial transposition map physically implementable. The main task for the two observers, Alice and Bob, is to measure some specific functions of the partial transposed matrix. With these functions, they can determine the eigenvalues of rho(T)(AB)(B), among which the minimum serves as an entanglement witness
