The Effects of Distance Between the Corneal Apex and the Inner and Outer Corneal Wound Edges on Corneal Astigmatism After Cataract Surgery
Authors: Kim Tae Gi , Noh Sung Rae , Jin Kyung Hyun 
Published: July 2017

PURPOSE:
To compare the effects of the distance from the inner and outer corneal incision wounds to the corneal apex on the changes in corneal astigmatism after cataract surgery.

METHODS:

Seventy-two eyes with anterior corneal astigmatism less than 2.50 diopters (D) were evaluated. The distance between the incision wound and the corneal apex was measured using the Pentacam (Oculus Optikgeräte, Wetzlar, Germany) Scheimpflug image and the Image J program (National Institutes of Health, Bethesda, MD). Patients were subgrouped into the inner incision distance close (less than 4,816.44
µ
m) and far (4,816.44
µ
m or greater) groups based on the median value of inner incision distance and the outer incision distance close (less than 6,131.77
µ
m) and far (6,131.77
µ
m or greater) groups based on the median value of outer incision distance.

RESULTS:
In the inner incision distance group, the mean change in anterior, posterior, and total corneal astigmatism at 1 week and anterior astigmatism at 1 month were statistically significantly greater in the inner incision close group than in the inner incision far group. In the outer incision distance group, the mean change in anterior corneal astigmatism at 1 week was statistically significantly greater in the close group than in the far group. Surgically induced astigmatism (SIA) of the posterior cornea showed a statistically significant increase in the inner incision close group compared to the inner incision far group 1 month postoperatively, whereas there were no significant differences in the outer incision distance groups. Inner incision distance significantly correlated with the mean change in anterior and posterior corneal astigmatism and posterior SIA at 1 week postoperatively.

CONCLUSIONS:
Corneal astigmatism was affected more by inner incision distance than outer incision distance, and a larger change in the posterior SIA was noted with decreasing inner incision distance. During cataract surgery, the position of the inner corneal incision should be considered rather than the outer incision.

Authors: Kim Paggie P C , Nasman Benjamin W , Kinne Erica L , Oyoyo Udochukwu E , Kido Daniel K , Jacobson J P 
Published: July 2017

Objectives:This study was undertaken to estimate the incidence and burden of cerebral microhemorrhage (CM) in patients with heart disease who underwent cardiopulmonary bypass (CPB), as detected on susceptibility-weighted imaging (SWI), a magnetic resonance (MR) sequence that is highly sensitive to hemorrhagic products.Materials and Methods:With Institutional Review Board waiver of consent, MR imaging (MRI) of a cohort of 86 consecutive pediatric patients with heart failure who underwent heart transplantation evaluation were retrospectively reviewed for CM. A nested case–control study was performed. The CPB group consisted of 23 pediatric patients with heart failure from various cardiac conditions who underwent CPB. The control group was comprised of 13 pediatric patients with similar cardiac conditions, but without CPB history. Ten patients in the CPB group were female (age: 5 days to 16 years at the time of the CPB and 6 days to 17 years at the time of the MRI). The time interval between the CPB and MRI ranged from 11 days to 4 years and 5 months. Six patients in the control group were female, age range of 2 days to 6 years old. The number of CM on SWI was counted by three radiologists (PK, EK and DK). The differences in number of CM between groups were tested for significance using Mann–Whitney U-test, α = 0.05. Using the univariate analysis of variance model, the differences in number of CM between groups were also tested with adjustment for age at MRI.Results:There are statistically significant differences in CM on SWI between the CPB group and control group with more CM were observed in the CPB group without and with adjustment for age at MRI (P< 0.001).Conclusions:Exposure of CPB is associated with increased prevalence and burden of CM among pediatric patients with heart failure.

ABSTRACT
Background: We evaluated short‑ and long‑term results of endoscopic drainage (a minimally invasive nonsurgical treatment) of pancreatic pseudocysts (PPCs) and factors associated with its success at a multilevel teaching hospital in Northern India, as such data are scanty from India. Patients and Methods: Retrospective review of records of consecutive patients undergoing endoscopic drainage of PPC from January 2002 to June 2013 was undertaken. Results: Seventy‑seven patients (56 males), median age 36 years (range, 15–73), underwent endoscopic drainage of PPC with 98% technical success. Pseudocysts drained were symptomatic (duration 11 weeks, range, 8–68), large (volume 582 mL [range, 80–2706]), located in head (n = 32, 46%), body and tail (n = 37, 54%), and infected (n = 39, 49%). Drainage procedures included cystogastrostomy (n = 54, 78%), cystoduodenostomy (n = 9, 13%), transpapillary drainage (n = 2, 3%), and multiple route (n = 4, 6%), with additional endoscopic nasocystic drainage (ENCD) in 41 (59%). Sixty‑nine patients were followed up (median 28 months, range 2–156; other eight lost to follow‑up). Complications (n = 21, 30%) included stent occlusion and migration (13), bleeding (5), perforation (2), and death (1). Endoscopic procedure had to be repeated in 19 patients (28%; 16 for sepsis, 3 for recurrence). The reasons for additional nonendoscopic treatment (n = 8, 12%) included incomplete cyst resolution (3), recurrence (2), bleeding (1), and perforation (2). Overall success rate of endoscopic drainage was 88%. Whereas infected pseudocysts were associated with poorer outcome (odds ratio [OR] 0.016; 95% confidence interval [CI] 0.001–0.037), placement of ENCD led to better results (OR 11.85; 95% CI 1.03–135.95). Conclusion: Endoscopic drainage is safe and effective for PPC.

As a consequence, we get that ifRis a left and right noetherian ring admitting a dualizing complex, thenandare equivalent.
Multiplicative Noise Removal Based on Unbiased Box-Cox Transformation
Authors: Huang Yu-Mei , Yan Hui-Yin , Zeng Tieyong 
Published: July 2017

AbstractMultiplicative noise removal is a challenging problem in image restoration. In this paper, by applying Box-Cox transformation, we convert the multiplicative noise removal problem into the additive noise removal problem and the block matching three dimensional (BM3D) method is applied to get the final recovered image. Indeed, BM3D is an effective method to remove additive Gaussian white noise in images. A maximum likelihood method is designed to determine the parameter in the Box-Cox transformation. We also present the unbiased inverse transform for the Box-Cox transformation which is important. Both theoretical analysis and experimental results illustrate clearly that the proposed method can remove multiplicative noise very well especially when multiplicative noise is heavy. The proposed method is superior to the existing methods for multiplicative noise removal in the literature.
Application of High Dimensional B-Spline Interpolation in Solving the Gyro-Kinetic Vlasov Equation Based on Semi-Lagrangian Method
Authors: Xiao Xiaotao , Ye Lei , Xu Yingfeng , Wang Shaojie 
Published: July 2017

AbstractThe computation efficiency of high dimensional (3D and 4D) B-spline interpolation, constructed by classical tensor product method, is improved greatly by precomputing the B-spline function. This is due to the character of NLT code, i.e. only the linearised characteristics are needed so that the unperturbed orbit as well as values of the B-spline function at interpolation points can be precomputed at the beginning of the simulation. By integrating this fixed point interpolation algorithm into NLT code, the high dimensional gyro-kinetic Vlasov equation can be solved directly without operator splitting method which is applied in conventional semi-Lagrangian codes. In the Rosenbluth-Hinton test, NLT runs a few times faster for Vlasov solver part and converges at about one order larger time step than conventional splitting code.
Constrained Interpolation Profile Conservative Semi-Lagrangian Scheme Based on Third-Order Polynomial Functions and Essentially Non-Oscillatory (CIP-CSL3ENO) Scheme

Published: July 2017

AbstractWe propose a fully conservative and less oscillatory multi-moment scheme for the approximation of hyperbolic conservation laws. The proposed scheme (CIP-CSL3ENO) is based on two CIP-CSL3 schemes and the essentially non-oscillatory (ENO) scheme. In this paper, we also propose an ENO indicator for the multimoment framework, which intentionally selects non-smooth stencil but can efficiently minimize numerical oscillations. The proposed scheme is validated through various benchmark problems and a comparison with an experiment of two droplets collision/separation. The CIP-CSL3ENO scheme shows approximately fourth-order accuracy for smooth solution, and captures discontinuities and smooth solutions simultaneously without numerical oscillations for solutions which include discontinuities. The numerical results of two droplets collision/separation (3D free surface flow simulation) show that the CIP-CSL3ENO scheme can be applied to various types of fluid problems not only compressible flow problems but also incompressible and 3D free surface flow problems.

Published: July 2017

AbstractIn this article, we study theoretically and numerically the interaction of a vortex induced by a rotating cylinder with a perpendicular plane. We show the existence of weak solutions to the swirling vortex models by using the Hopf extension method, and by an elegant contradiction argument, respectively. We demonstrate numerically that the model could produce phenomena of swirling vortex including boundary layer pumping and two-celled vortex that are observed in potential line vortex interacting with a plane and in a tornado.
Runge-Kutta Central Discontinuous Galerkin Methods for the Special Relativistic Hydrodynamics
Authors: Zhao Jian , Tang Huazhong 
Published: July 2017

AbstractThis paper develops Runge-Kutta PK-based central discontinuous Galerkin (CDG) methods with WENO limiter for the one- and two-dimensional special relativistic hydrodynamical (RHD) equations, K = 1,2,3. Different from the non-central DG methods, the Runge-Kutta CDG methods have to find two approximate solutions defined on mutually dual meshes. For each mesh, the CDG approximate solutions on its dual mesh are used to calculate the flux values in the cell and on the cell boundary so that the approximate solutions on mutually dual meshes are coupled with each other, and the use of numerical flux will be avoided. The WENO limiter is adaptively implemented via two steps: the “troubled” cells are first identified by using a modified TVB minmod function, and then the WENO technique is used to locally reconstruct new polynomials of degree (2K+1) replacing the CDG solutions inside the “troubled” cells by the cell average values of the CDG solutions in the neighboring cells as well as the original cell averages of the “troubled” cells. Because the WENO limiter is only employed for finite “troubled” cells, the computational cost can be as little as possible. The accuracy of the CDG without the numerical dissipation is analyzed and calculation of the flux integrals over the cells is also addressed. Several test problems in one and two dimensions are solved by using our Runge-Kutta CDG methods with WENO limiter. The computations demonstrate that our methods are stable, accurate, and robust in solving complex RHD problems.

El presente trabajo recoge parte de los resultados obtenidos en el marco del proyecto de innovación docente “Herramientas para la planificación, realización y valoración de los Trabajo Fin de Grado (TFGs)”. Se pretende resolver la problemática a la que se enfrenta el alumnado, los tutores y los tribunales en cuanto a los criterios de valoración de los TFGs, aportando herramientas para su evaluación (rúbricas). Actualmente, no existen unos criterios claros y objetivos para la evaluación de los TFGs, quedando en ocasiones su calificación sometida a valoraciones subjetivas, por parte del tribunal evaluador. Así, es más detallado el documento para la evaluación de las competencias trasversales que el utilizado para la evaluación del TFG. Por tanto, es necesario desarrollar un documento “Guía del Trabajo Fin de Grado”, que proporcione instrumentos para una adecuada y óptima planificación y evaluación de los TFGs. Uno de los puntos clave del proyecto, ha sido la elaboración de una rúbrica con indicadores medibles que faciliten y clarifiquen la evaluaciónn de los TFGs. Dicha rúbrica, se pasará a los diferentes grupos de interés (profesorado, alumnado y comisiones académicas) para mejorarla y validarla. Palabras clave: evaluación, valoración, criterios, rúbrica

On the meridional ageostrophic transport in the tropical Atlantic
Authors: Fu Yao , Karstensen Johannes , Brandt Peter 
Published: July 2017

Abstract. The meridional Ekman volume, heat, and salt transport across two trans-Atlantic sections near 14.5° N and 11° S were estimated using in situ observations, wind products, and model data. A meridional ageostrophic velocity was obtained as the difference between the directly measured total velocity and the geostrophic velocity derived from observations. Interpreting the section mean ageostrophy to be the result of an Ekman balance, the meridional Ekman transport of 6.2±2.3 Sv northward at 14.5° N and 11.7±2.1 Sv southward at 11° S is estimated. The integration uses the top of the pycnocline as an approximation for the Ekman depth, which is on average about 20 m deeper than the mixed layer depth. The Ekman transport estimated based on the velocity observations agrees well with the predictions from in situ wind stress data of 6.7±3.5 Sv at 14.5° N and 13.6±3.3 Sv at 11° S. The meridional Ekman heat and salt fluxes calculated from sea surface temperature and salinity data or from high-resolution temperature and salinity profile data differ only marginally. The errors in the Ekman heat and salt flux calculation were dominated by the uncertainty of the Ekman volume transport estimates.
Debunking Neosocialism
Authors: Jason Gary James 
Published: July 2017

Abstract
In this article, the author reviews in detail Christopher Snowdon's recent monograph Selfishness, Greed, and Capitalism: Debunking Myths about the Free Market. In the book, Snowdon sets about to debunk a number of distortions of—and outright myths about—free market economics. The distortions include strawmen such as the claim that free market economics assumes all people are motivated solely by selfish greed. The myths include views such as the Easterlin Paradox. The author suggests a number of ways Snowdon's analysis could have been improved.

A região de Carajás (constituída principalmente das cidades de Marabá, Parauapebas, Curionópolis, Canaã dos Carajás e Eldorado dos Carajás) no estado do Pará e a região de São Luís no estado do Maranhão são os polos mais importantes para a companhia Vale do Rio Doce. Assim, nesta pesquisa foi realizada uma análise das variáveis meteorológicas, temperatura (máxima, mínima e amplitude térmica) e precipitação para essas duas localidades. Foi calculada a correlação entre o gradiente térmico continental e o marítimo com a variabilidade pluviométrica sazonal da Amazônia oriental objetivando identificar o principal modulador da precipitação da região de estudo. Observou-se que a variabilidade climática da temperatura, tanto do ar como do oceano, nas duas regiões estudadas, apresentam um padrão semelhante de crescimento, resultado que produz resultados diferentes sobre a precipitação de cada localidade. Foi identificado que a intensidade da anomalia térmica no Nino 4, localizado a 5N-5S, 160E-150W no oceano atlântico, interfere diretamente sobre as variáveis meteorológicas no sudeste da Amazônia oriental e que a anomalia de TSM do oceano Pacífico possui maior correlação com a variabilidade pluviométrica da cidade de São Luís. .

Nos últimos anos o método de Análise de Espectro Singular (SSA- Singular Spectrum Analysis) tem sido utilizado como uma técnica na análise de séries temporais de dados meteorológicos e climáticos, possibilitando extrair informações úteis a partir de séries temporais estudadas. Nessa pesquisa, essa técnica foi utilizada no estudo das variáveis de temperatura do ar e umidade relativa em Cuiabá dos anos de 2000 a 2013, utilizando dados fornecidos pelo Instituto Nacional de Meteorologia (INMET). O foco principal do estudo foi extrair informações sobre as tendências e efeitos sazonais das séries temporais. A ação conjunta desses dois fatores é particularmente evidente no caso da temperatura, que apresenta, comumente, dois máximos anuais.
AVALIAÇÃO DOS IMPACTOS DAS MUDANÇAS CLIMÁTICAS NA RECICLAGEM DE PRECIPITAÇÃO DA AMAZÔNIA: UM ESTUDO DE MODELAGEM NUMÉRICA (ASSESSMENT OF THE IMPACTS OF CLIMATE CHANGE ON PRECIPITATION RECYCLING IN THE AMAZON BASIN: A NUMERICAL MODELING STUDY)
Authors: Rocha Vinícius Machado 
Published: July 2017

RESUMO: O presente trabalho envolvendo modelagem climática é transcrição de palestra proferida pelo autor durante o XII SBCG, realizado no mês de outubro de 2016 na cidade de Goiânia/GO. A principal ferramenta para avaliar as variabilidades e mudanças do clima são os modelos climáticos globais e regionais, capazes de representar as complexas interações entre o oceano, a atmosfera e a superfície terrestre. Com base nas simulações do modelo regional RCP 8.5 Eta-HadGEM2-ES, discute-se de que maneira o aumento dos gases de efeito estufa pode afetar o balanço de umidade e a reciclagem de precipitação na Amazônia durante o século XXI. Para quantificar a reciclagem de precipitação foi utilizado um método fundamentado no balanço de umidade na atmosfera. Na média anual, a reciclagem na bacia amazônica simulada pelo modelo para o clima presente é de 22%. As mudanças projetadas para o clima futuro mostram que, a redução da reciclagem é mais pronunciada na estação seca, atingindo 40% ao final do século. Os resultados sugerem que, as mudanças climáticas poderão acarretar graves consequências ecológicas à Amazônia, tais como: impactos na dinâmica dos ecossistemas, redução da capacidade da floresta em absorver carbono, aumento na ocorrência de eventos extremos e na frequência das queimadas.
