BACKGROUND: The field of eHealth is growing rapidly and chaotically. Health care professionals need guidance on reviewing and assessing health-related smartphone apps to propose appropriate ones to their patients. However, to date, no framework or evaluation tool fulfills this purpose. OBJECTIVE: Before developing a tool to help health care professionals assess and recommend apps to their patients, we aimed to create an overview of published ...

Stimulating and developing talents of all young people is an important goal of education and student counseling. Educational policy in Flanders already pays extensive attention to students with specific educational needs. However, to ensure that our society can remain innovative and prosperous, it is important to focus education and student support also on students with outstanding cognitive abilities. This dissertation revolves around the broad ...

Photonic reservoir computing (RC) has been effectively used for solving various complex problems. Such a reservoir consists of a network of randomly, untrained connected nodes. Doing RC in the photonics domain offers the advantage of high-speed performance, low-energy consumption and the possibility of high inherent parallelism. We propose and numerically investigate to use the output of such a reservoir to preprocess the input data before this ...

The Hungarian physicist Eugene Wigner introduced random matrix models in physics to describe the energy spectra of atomic nuclei. As such, the main goal of Random Matrix Theory (RMT) has been to derive the eigenvalue statistics of matrices drawn from a given distribution. The Wigner approach gives powerful insights into the properties of complex, chaotic systems in thermal equilibrium. Another Hungarian, Cornelius Lanczos, suggested a method of ...

Despite the benefits of lifelong organized sports participation (i.e., sports participation in sports clubs), a significant number of sports club members quit organized sports as they grow older. An abundant number of SDT studies have proven that the context of the sports club has an important influence on members' dropout, highlighting the role of the coach in members' attitude towards their sport. In addition, SDT literature suggests that the ...

The genus Agrobacterium was initially described as mainly phytopathogenic strains. Nowadays, the genus includes phytopathogenic and non-phytopathogenic bacteria that are distinctive among the Rhizobiaceae family. Recently we have isolated two closely related strains, LMG 31531T and LMG 31532, from soil and plant roots, respectively. Both strains differ from previously reported species based on the genomic and phenotypic data. A. arsenijevicii ...

Event-based cameras are novel bio-inspired vision sensors that do not follow the mechanism of traditional frame-based cameras. In the field of data acquisition, the replacement of CMOS cameras with event-based cameras has proved to enhance the accuracy of machine learning methods in situations where critical lighting conditions and rapid dynamics are paramount. In this paper, we investigate for the first time the use of extreme learning machines ...

The paper deals with multi-layer canard cycles, extending the results of [1]. As a practical tool we introduce the connection diagram of a canard cycle and we show how to determine it in an easy way. This connection diagram presents in a clear way all available information that is necessary to formulate the main system of equations used in the study of the bifurcating limit cycles. In a forthcoming paper we will show that both the type of the ...
