13. Phantoms for diffusion-weighted imaging and diffusion tensor imaging quality control: a review and new perspectives
Abstract: Introduction Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) combine magnetic resonance imaging (MRI) techniques and diffusion measures. In DWI, the contrast is defined by microscopic motion of water protons. Nowadays, DWI has become important for early diagnostic of acute stroke. DTI images are calculated from DWI images acqui

14. NSGA-II-Based Multi-objective Mission Planning Method for Satellite Formation System
ABSTRACT This study proposes a non-dominated sorting genetic algorithm-II-based multi-objective optimization method to solve the multi-objective mission planning problem for satellite formation flying system which has the ability to obtain both digital elevation map and ground moving target indicator information at the same time when certain conditions are s

15. Estimating the efficiency from Brazilian banks: a bootstrapped Data Envelopment Analysis (DEA)
Abstract The Brazilian banking sector went through several changes in its structure over the past few years. Such changes are related to fusions and acquisitions, as well as the largest market opening to foreign banks. The objective of this paper is to analyze, by applying the bootstrap DEA, the efficiency of banks in Brazil in 2010-2013. The methodology was

16. Inductive plethysmography potential as a surrogate for ventilatory measurements during rest and moderate physical exercise
Background: Portable respiratory inductive plethysmography (RIP) systems have been validated for ventilatory assessment during resting conditions and during incremental treadmill exercise. However, in clinical settings and during field-based exercise, intensity is usually constant and submaximal. A demonstration of the ability of RIP to detect respiratory m

17. Detection of horizontal root fracture using four different protocols of cone-beam computed tomography
The purpose of this study was to analyze four different cone-beam computed tomography (CBCT) protocols to identify horizontal root fractures (HRF) in endodontically treated teeth, with or without the presence of a metallic post. Thirty extracted single-rooted human premolars were treated endodontically. Afterwards, an observer induced a horizontal fracture i

18. Pharyngeal airway space cephalometric evaluation in transverse maxillary deficient patients after SARME
Aim: To evaluate prospectively the upper airway of 16 patients submitted to surgically assisted rapid maxillary expansion. Methods: Volumetric tomography acquisitions were done preoperatively (T1) and after six months postoperatively (T2), the slices were obtained from the hard palate to the third cervical vertebra (C3), the images were imported and reconstr

19. Evaluation of nuclear magnetic resonance spectroscopy variability
INTRODUCTION: The intrinsically high sensitivity of Magnetic Resonance Spectroscopy (MRS) causes considerable variability in metabolite quantification. In this study, we evaluated the variability of MRS in two research centers using the same model of magnetic resonance image scanner. METHODS: Two metabolic phantoms were created to simulate magnetic resonance

20. Multilatinas and value creation from cross-border acquisitions:: an event study approach
The central proposition of this paper is to assess the performance of cross-border acquisitions made by Multilatinas. Applying the event study method to a sample of 607 announcements of acquisitions during the period 1989-2011 by 182 Multilatinas from Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela, we conclude that: (a) on average, these anno

21. The non-economic dimension of changes prompted by cross-border acquisitions: a relational view
A partir da visão relacional de F&A proposta pela Abordagem de Redes Industriais, investigamos a dimensão não econômica das mudanças pós-aquisição nos relacionamentos da firma adquirida. Baseado em uma matriz 2 x 2, essa dimensão é ilustrada pelos relacionamentos da adquirida com organizações com fins lucrativos nos quais recursos não econômico

22. Advances in the treatment of children with phonological disorders
INTRODUCTION: Treatment of phonological disorders considering extra-linguistic and linguistic variables are important to ensure that the alteration is resolved promptly and in the best manner as possible. AIM: To analyze therapeutic advances (phonetic inventory, phonological system, and distinctive features) in children with phonological disorders by conside

23. Effect of scanner acoustic background noise on strict resting-state fMRI
Functional MRI (fMRI) resting-state experiments are aimed at identifying brain networks that support basal brain function. Although most investigators consider a ‘resting-state’ fMRI experiment with no specific external stimulation, subjects are unavoidably under heavy acoustic noise produced by the equipment. In the present study, we evaluated the influ

24. Value creation in mergers and acquisitions: the market sentiment influence / Criação de valor em fusões e aquisições: a influência do sentimento de mercado
Mergers and Acquisitions (M&As) finance literature is vast and extensive, being one of its main themes of research the value creation (or destruction) determinants in these processes. More recently, with behavioral finance theory development, the market condition (bull or bear market) during M&As announcements has increasinly attracted researches attention.
