Gray-matter-specific MR imaging improves the detection of epileptogenic zones in focal cortical dysplasia: A new sequence called fluid and white matter suppression (FLAWS)

Xin Chen, Tobias Kober, Thomas Yu, Nan Chen

Objectives: To evaluate the diagnostic value and characteristic features of FCD epileptogenic zones using a novel sequence called fluid and white matter suppression (FLAWS). Materials and methods: Thirty-nine patients with pathologically confirmed FCD and ...

Scalable Low-rank Matrix and Tensor Decomposition on Graphs

Nauman Shahid

In many signal processing, machine learning and computer vision applications, one often has to deal with high dimensional and big datasets such as images, videos, web content, etc. The data can come in various forms, such as univariate or multivariate time ...

Fourier dimensionality reduction of radio-interferometric data

Jean-Philippe Thiran, Yves Wiaux, Rafael Eduardo Carrillo Rangel, Vijay Kartik

Next-generation radio-interferometers face a computing challenge with respect to the imaging techniques that can be applied in the big data setting in which they are designed. Dimensionality reduction can thus provide essential savings of computing resourc ...

How close are the eigenvectors and eigenvalues of the sample and actual covariance matrices?

Andreas Loukas

How many samples are sufficient to guarantee that the eigenvectors and eigenvalues of the sample covariance matrix are close to those of the actual covariance matrix? For a wide family of distributions, including distributions with finite second moment and ...

Exploring Variability in Reflood Simulation Results: an Application of Functional Data Analysis

Andreas Pautz, Damar Canggih Wicaksono, Omar Zerkak

In this paper we followed the functional data analysis (FDA) paradigm to summarize the output of computer code simulating a reflood transient. The paradigm stands on the assumption that the data (code output) is generated by a smooth, albeit complex, proce ...

Distributed static linear Gaussian models using consensus

Pavle Belanovic

Algorithms for distributed agreement are a powerful means for formulating distributed versions of existing centralized algorithms. We present a toolkit for this task and show how it can be used systematically to design fully distributed algorithms for stat ...

Stability Study of a Complete Hydroelectric Production Site by Eigenvalues Analysis Method Based on Phase Variables

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Basile Kawkabani, Sébastien Alligné, Pedro Camilo de Oliveira e Silva

The eigenvalues analysis method is generally applied to synchronous machines by using d,q-components. This paper presents the application of this method on an equivalent model for the synchronous machine based on phase variables a,b,c instead of d,q-compon ...

The 'intrinsic' system in the human cortex and self-projection: a data driven analysis

Olaf Blanke

Information received by the human cortex is supplied by two main sources: extrinsic stimuli delivered by the external environment and intrinsic information regarding the body and self. We reanalyzed electrophysiological data involving the same external sti ...

Stakeholder-based Scenarios for Post-2012 Climate Policy: A Participatory Approach

Philippe Thalmann, Juan Carlos Altamirano Cabrera, Ronal Gainza Carmenates, José Luis Carrasco Terceros

We performed a study to define the key elements of feasible global climate policy scenarios for the post-2012 UNFCCC regime by contacting – through a series of questionnaires – 149 stakeholders involved in climate-change discussions. We applied a Multiple ...

Classification of magnetic resonance images from rabbit renal perfusion

Dominique Bonvin, Michael Amrhein, Pamandeep Singh Gujral

The feasibility of using chemometric techniques for the automatic detection of whether a rabbit kidney is pathological or not is studied. Sequential images of the kidney are acquired using Dynamic Contrast-Enhanced Magnetic Resonance Imaging with contrast ...
