XStrain 4D analysis predicts left ventricular remodeling in patients with recent non-ST-segment elevation myocardial infarction

Tako-tsubo cardiomyopathy and microcirculation.

2010

Takotsubo cardiomyopathy was described for the first time in Japan in the 1990s. It is very similar to the ischemic cardiopathy both for clinical and instrumental characteristics. His peculiarity is an alteration of the ventricular contraction mechanism with hypo-akinesis of the apex and lateral segments of the left ventricle, associated with hyper-kinesis of the heart base which is responsible for the typical echocardiographic aspect of a cruet during the systole. However, the etiology of this cardiomyopathy is still unknown despite the fact that numerous hypothesis have been made. A single study of 16 patients proved multivasal damage by a BLASH SCORE analysis of the coronary radiography.…

Weighted Least-Squares Likelihood Ratio Test for Branch Testing in Phylogenies Reconstructed from Distance Measures

2005

A variety of analytical methods is available for branch testing in distance-based phylogenies. However, these methods are rarely used, possibly because the estimation of some of their statistics, especially the covariances, is not always feasible. We show that these difficulties can be overcome if some simplifying assumptions are made, namely distance independence. The weighted least-squares likelihood ratio test (WLS-LRT) we propose is easy to perform, using only the distances and some of their associated variances. If no variances are known, the use of the Felsenstein F-test, also based on weighted least squares, is discussed. Using simulated data and a data set of 43 mammalian mitochondr…

Beyond path dependence: Explorative orientation, slack resources, and managerial intentionality to internationalize in SMEs

2015

Abstract Managerial intentionality plays an important role in a firm's selection of its internationalization path. In relation to small and medium sized enterprises (SMEs), most studies focus on the individual traits that foster managerial intentionality without considering organizational-level antecedents. This study seeks to address this gap by focusing on two organizational antecedents: the firm's exploration and exploitation orientations, and its slack resources. The firm's orientations affect the application of different learning processes, including knowledge acquisition, information interpretation, and knowledge diffusion, and they shape the subjective norms prevalent in the organiza…

Estimation of the elastic parameters of human liver biomechanical models by means of medical images and evolutionary computation.

2013

This paper presents a method to computationally estimate the elastic parameters of two biomechanical models proposed for the human liver. The method is aimed at avoiding the invasive measurement of its mechanical response. The chosen models are a second order Mooney–Rivlin model and an Ogden model. A novel error function, the geometric similarity function (GSF), is formulated using similarity coefficients widely applied in the field of medical imaging (Jaccard coefficient and Hausdorff coefficient). This function is used to compare two 3D images. One of them corresponds to a reference deformation carried out over a finite element (FE) mesh of a human liver from a computer tomography image, …

Parametric and nonparametric methods to generate time-varying surrogate data.

2009

We present both nonparametric and parametric approaches to generating time-varying surrogate data. Nonparametric and parametric approaches are based on the use of the short-time Fourier transform and a time-varying autoregressive model, respectively. Time-varying surrogate data (TVSD) can be used to determine the statistical significance of the linear and nonlinear coherence function estimates. Two advantages of the TVSD are that it keeps one from having to make an arbitrary decision about the significance of the coherence value, and it properly takes into account statistical significance levels, which may change with time. Our simulation examples and experimental results on blood pressure …

A Preference-Based Evolutionary Algorithm for Multi-Objective Optimization

2009

In this paper, we discuss the idea of incorporating preference information into evolutionary multi-objective optimization and propose a preference-based evolutionary approach that can be used as an integral part of an interactive algorithm. One algorithm is proposed in the paper. At each iteration, the decision maker is asked to give preference information in terms of his or her reference point consisting of desirable aspiration levels for objective functions. The information is used in an evolutionary algorithm to generate a new population by combining the fitness function and an achievement scalarizing function. In multi-objective optimization, achievement scalarizing functions are widel…

Theory of Legal Interpretation and Contextualism. Replies to Kristan, Poggi and Vignolo

2012

In this essay I will attempt to answer the critical observations made by Kristan, Poggi and Vignolo of my theory of legal interpretation. I express the opinion that, apart from some gaps and defects to be addressed, my theory can satisfactorily overcome this criticism. In answering these observations, I again stress the fruitfulness of moderate contextualism as a semantical point of reference for legal interpretation, also striving to deepen the notion of “background context”, and to clarify the differences among four types of interpretative disagreements. I also maintain that the most important and problematic issues in interpretative legal practices today are those which express, as in bi…

The composition of phytoplankton community is the basis for environmental monitoring and assessment of the ecological status of aquatic ecosystems. Community composition studies of phytoplankton have been based on time-consuming and expertise-demanding light microscopy analyses. Molecular methods have the potential to replace microscopy, but the high copy number variation of ribosomal genes and the lack of universal primers for simultaneous amplification of prokaryotic and eukaryotic genes complicate data interpretation. In this study, we used our previously developed directional primer-independent high-throughput sequencing (HTS) approach to analyze 16S and 18S rRNA community structures. C…
