Reviews of acupuncture for chronic neck pain: pitfalls in conducting systematic reviews
No full textThis paper examines some of the problems specifically associated with conducting research into acupuncture and how this can lead to further problems with subsequent systematic reviews. Studies for the treatment of chronic neck pain have been used as examples of how presented information can be misleading to an acupuncture-naive reader and how researchers must be sensitive to these problems when compiling their inclusion and exclusion criteria. The problems associated with scoring trials are discussed and further work to increase the scope of scoring mechanisms is recommended in order to produce meaningful systematic reviews in the future

Adiabaticity conditions for volatility smile in Black-Scholes pricing model
No full textOur derivation of the distribution function for future returns is based on the risk neutral approach which gives a functional dependence for the European call (put) option price C(K) given the strike price K and the distribution function of the returns. We derive this distribution function using for C(K) a Black-Scholes expression with volatility σ in the form of a volatility smile. We show that this approach based on a volatility smile leads to relative minima for the distribution function (“bad" probabilities) never observed in real data and, in the worst cases, negative probabilities. We show that these undesirable effects can be eliminated by requiring “adiabatic" conditions on the volatility smile. Copyright EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg 2011
Influence of high-protein and high-carbohydrate diets on serum lipid and fructosamine concentrations in healthy cats
No full textObjectives: The aim of this study was to determine whether high-protein and high-carbohydrate diets exert differential effects on serum cholesterol, triglyceride and fructosamine concentrations in healthy cats. Methods A randomised, crossover diet trial was performed in 35 healthy shelter cats. Following baseline health assessments, cats were randomised into groups receiving either a high-protein or high-carbohydrate diet for 4 weeks. The cats were then fed a washout diet for 4 weeks before being transitioned to whichever of the two studied diets they had not yet received. Fasting serum cholesterol, triglyceride and fructosamine concentrations were determined at the end of each 4-week diet period. Results Cats on the high-carbohydrate diet had significantly lower serum cholesterol ( P 5) had lower cholesterol ( P = 0.007) and triglyceride ( P = 0.032) concentrations on the high-protein diet than cats within other BCS groups. Conclusions and relevance Diets higher in protein and lower in carbohydrates appear beneficial for short-term glucose control in healthy cats. A high-protein diet was associated with significantly elevated cholesterol and triglyceride concentrations in healthy cats, even though the increase was significantly less pronounced in cats with a BCS >5. This finding suggests that overweight cats process high-protein diets, cholesterol and triglycerides differently than leaner cats
Quantum logic operations and creation of entanglement in a scalable superconducting quantum computer with long-range constant interaction between qubits
No full textWe consider a one-dimensional chain of many superconducting quantum interference devices (SQUIDs), serving as charge qubits. Each SQUID is coupled to its nearest neighbor through constant capacitances. We study the quantum logic operations and implementation of entanglement in this system. Arrays with two and three qubits are considered in detail. We show that the creation of entanglement with an arbitrary number of qubits can be implemented, without systematic errors, even when the coupling between qubits is not small. A relatively large coupling constant allows one to increase the clock speed of the quantum computer. We analytically and numerically demonstrate the creation of the entanglement for this case, which can be a good test for the experimental implementation of a relatively simple quantum protocol with many qubits. The logic operations in a system with long-range interaction are not universal. We discuss a possible application of our approach for implementing universal quantum logic for more complex algorithms by decreasing the coupling constant and, correspondingly, decreasing the clock speed. The errors introduced by the long-range interaction for the universal logic gates are estimated analytically and calculated numerically. Our results can be useful for experimental implementation of quantum algorithms using controlled magnetic fluxes and gate voltages applied to the SQUIDs. The algorithms discussed in this paper can be implemented using already existing technologies in superconducting systems with constant interqubit coupling
Retradução comentada de Corinne ou l'Italie de Mme de Staël
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2014.Esta tese, vinculada à linha da "Teoria, crítica e história da tradução" objetiva a retradução comentada de Corinne ou l'Italie (1807) de Madame de Staël. No primeiro capítulo, descrevem-se a vida e as obras da autora, com ênfase para Corinne ou l'Italie, que foi traduzida e retraduzida em outras línguas, principalmente o inglês, italiano e alemão. Em seguida, no capítulo 2, apresenta-se a primeira tradução para o português do Brasil Corina ou a Itália (1945, Edições Cultura). Como terceira etapa, comenta-se a retradução com base nas reflexões teóricas de Berman, Pym, Venuti, Gambier. Apresentam-se exemplos dos aspectos semânticos, culturais, estilísticos presentes ao longo dos XX livros, a partir do original e da retradução. Os comentários do processo de tradução permitem uma frutífera troca literária e cultural e a tradução, o estudo e conhecimento da obra de Madame de Staël, por consequência, enriquecem o cânone da literatura francesa traduzida no Brasil.Abstract : This thesis, linked to the research field "Theory, criticism and history of translation" attempts to do a commented retranslation of Mme de Staël's Corinne ou l'Italie (1807). The first chapter describes the life and the works of the author, with emphasis on Corinne ou l'Italie, which was translated and retranslated into other languages, mainly English, Italian and German. In Chapter 2, the first translation of Corinne ou l'Italie into Brazilina Portuguese (1945, Cultura Printings) is presented. In chapter 3 the retranslation is analyzed through comments based on theoretical reflections of Berman, Pym, Venuti and Gambier. Examples of semantic, cultural and stylistics aspects of the XX books (original and retranslated version) are presented. The comments of the translation process allow a rich literary and cultural exchange. As well as a deeper investigation about Madame de Staël's work enriches the standard of French literature in Brazil
Evidence of an oceanic impact and megatsunami sedimentation in Chryse Planitia, Mars.
No full textIn 1976, NASA's Viking 1 Lander (V1L) was the first spacecraft to operate successfully on the Martian surface. The V1L landed near the terminus of an enormous catastrophic flood channel, Maja Valles. However, instead of the expected megaflood record, its cameras imaged a boulder-strewn surface of elusive origin. We identified a 110-km-diameter impact crater (Pohl) ~ 900 km northeast of the landing site, stratigraphically positioned (a) above catastrophic flood-eroded surfaces formed ~ 3.4 Ga during a period of northern plains oceanic inundation and (b) below the younger of two previously hypothesized megatsunami deposits. These stratigraphic relationships suggest that a marine impact likely formed the crater. Our simulated impact-generated megatsunami run-ups closely match the mapped older megatsunami deposit's margins and predict fronts reaching the V1L site. The site's location along a highland-facing lobe aligned to erosional grooves supports a megatsunami origin. Our mapping also shows that Pohl's knobby rim regionally represents a broader history of megatsunami modification involving circum-oceanic glaciation and sedimentary extrusions extending beyond the recorded megatsunami emplacement in Chryse Planitia. Our findings allow that rocks and soil salts at the landing site are of marine origin, inviting the scientific reconsideration of information gathered from the first in-situ measurements on Mars
Comparison of the Berman Intubating Airway and the Williams Airway Intubator for fibreoptic orotracheal intubation in anaesthetised patients
No full textSixty patients with no clinical indicators of a difficult airway were selected to undergo a fibreoptic assessment after induction of general anaesthesia using both the Berman Intubating Airway and the Williams Airway Intubator. The bronchoscopic view and ease of railroading a tracheal tube during fibreoptic orotracheal intubation were studied. The bronchoscopic views obtained by the Berman Airway and the Williams Airway were significantly different (p < 0.008, test of symmetry). The estimated odds ratio of obtaining an obstructed path was 3.06 times higher for the Berman than the Williams Airway. However, if the glottis could be reached with the bronchoscope, there was no significant difference in the degree of ease of intubation between the two airways
