Study of Serum Uric Acid In Liver Cirrhosis and Its Correlation with Child Turcotte Pugh Score
No full textBACKGROUND: Cirrhosis cannot be accurately diagnosed by a serologic test. Even though aberrant biochemical patterns in combination with the clinical picture can point to certain liver illnesses, liver function tests may not always accurately reflect hepatic function. Hyperuricemia was found to be a risk factor for liver diseases. So, this study is an opportunity to determine serum uric acid level in liver cirrhosis and its correlation with Child Turcotte Pugh score.
AIM OF THE STUDY:
To study serum uric acid level in liver cirrhosis and its correlation with Child Turcotte Pugh score.
OBJECTIVES:
1. To determine serum uric acid level and Child Turcotte Pugh score among patients with liver cirrhosis.
2. To study the correlation between serum uric acid level and Child Turcotte Pugh score among patients with liver cirrhosis.
METHODS: A prospective study among patients with liver cirrhosis was conducted in a tertiary care centre with eight samples using simple random sampling. Their serum uric acid and CTP score was estimated and analysed using descriptive and inferential statistics by SPSS software.
RESULTS: 36.3% of patients had Class A score, 31.3% had Class B score and 32.5% of them had Class C scores. The mean uric acid value was 5.621+1.861 mg/dL ranging from 3.4 — 10.9.
There was a significant (0.0001) positive correlation (r value 0.642) between serum uric acid and Child Turcotte Pugh score among patients with liver cirrhosis.
CONCLUSION: Child Pugh score increases together with serum uric acid levels, suggesting that uric acid estimate may be a useful and affordable diagnostic marker for assessing the degree of liver cirrhosis
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
CPU, SMP and GPU implementations of Nohalo level 1, a fast co-convex antialiasing image resampler
No full textThis article introduces Nohalo level 1 (“Nohalo”), the simplest member of a family of image resamplers which straighten diagonal interfaces without adding noticeable nonlinear artifacts. Nohalo is interpolatory, co-monotone, coconvex, antialiasing, local average preserving, continuous, and exact on linears. Like many edge-enhancing methods, Nohalo has two main stages: first, nonlinear interpolation is used to create a double-density version of the original image; this doubledensity image is then resampled with bilinear interpolation. Nohalo is especially suited for GPU computing because the nonlinear slopes can be computed once and stored in a low bit-depth texture without rounding error, because the final bilinear stage can be performed in hardware, and because monotonicity allows full use of the texture’s dynamic range. Demand-driven implementations for CPUs and SMPs are more complex, and require extra work to fix bottlenecks. Efficient implementations of the minmod function are key to performance. Three implementations of Nohalo are presented and benchmarked: a CPU version in C for the graphics library GEGL, an SMP version in C++ for the graphics library VIPS and a GPU version in HLSL for DirectX. The GPU implementation is branch-free thanks to the discovery of a simple formula for the pixel values of the double density image. Branches are eliminated in the demand-driven C/C++ implementations by reflecting, if needed, Nohalo’s 12-point stencil with pointer shifts. Overall, Nohalo is not much slower than standard bicubic resamplers. Compared to twenty-three alternatives in tests involving the re-enlargement of images downsampled with nearest neighbour, Nohalo gets the best PSNRs
"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.
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

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

L’intoxication en contexte suicidaire et les deux sens de l’acte volontaire en droit criminel canadien : une critique de l’arrêt R. c. Turcotte
No full textLe présent article se veut une critique de l’arrêt prononcé par la Cour d’appel du Québec en 2013 qui a conduit à l’annulation du premier verdict de non-responsabilité criminelle dans l’affaire R. c. Turcotte. Après avoir insisté sur la relative indétermination des critères qui régissent le pouvoir d’intervention des tribunaux en semblable matière, l’auteur s’efforce de dévoiler les lacunes de plusieurs raisonnements qui fondent cette décision. Outre que la Cour d’appel n’a pas tenu compte de la polysémie constitutive de la notion d’acte volontaire en droit canadien lorsqu’elle a qualifié l’intoxication, l’auteur soutient qu’elle a omis de rendre justice à la trame factuelle inédite de l’affaire, notamment en évacuant le rôle déterminant joué par le raptus suicidaire dans la genèse des évènements. Enfin, l’auteur fait valoir que le tribunal s’est substitué au juge du procès dans l’appréciation des faits et qu’il a permis, à tort, à la poursuite de modifier fondamentalement son argumentation en appel.This article reviews the decision of the Quebec Court of Appeal in the Turcotte case, which set aside the first verdict of not criminally responsible in 2013. After highlighting the relative indeterminacy of the criteria which govern the power of intervention of the courts in this field, the author explains the deficiencies of several of the arguments underlying the judgment. In addition to the Court of Appeal’s failure to take into account the polysemous nature of the notion of voluntary act in Canadian law when it characterizes intoxication, the author argues that it failed to do justice to the unprecedented factual framework for the case, notably by ignoring the determining role of the suicidal crisis in the unfolding of events. Finally, the author argues that the court substituted itself for the trial judge in assessing the facts and wrongly allowed the prosecution to make substantial changes to its initial argument at the time of the appeal.Este artículo realiza una crítica de la decisión pronunciada por el Tribunal de Apelaciones de Quebec en el año 2013, en la cual se dejó sin efecto la primera decisión dictada, y en la que se declaraba la exención de responsabilidad penal en el caso Turcotte.

El Tribunal de Apelaciones no consideró la polisemia constitutiva de la noción de acto voluntario en el derecho canadiense cuando realizó la calificación de la intoxicación.

Finalmente, el autor argumenta que el tribunal ha suplantado al juez de la causa en la valoración de los hechos, y que se permitió indebidamente que la fiscalía modificara de manera sustancial su argumentación en la apelación
