Rapid neural encoding of the contrast between native and nonnative speech in the alpha band

2021

AbstractMore than half of the world’s population is multilingual, yet it is not known how the human brain encodes the perception of native vs. nonnative speech. To find out, we asked German native speakers to detect the onset of native and nonnative (English and Turkish) vowels in a roving standard stimulation. Using EEG, we show that nonnativeness is robustly registered by an increase in phase coherence in the alpha band (8-12 Hz), beginning as early as ∼100 ms after stimulus onset and lasting more than 200 ms. The alpha band effect is speech-specific, successfully predicts the response speed advantage of nonnative speech, and grants ∼90% decoding accuracy in distinguishing native vs. nonn…

Fuzzy-based Kernel Regression Approaches for Free Form Deformation and Elastic Registration of Medical Images

2009

In modern medicine, a largely diffused method for gathering knowledge about organs and tissues is obtained by means of merging information from several datasets. Such data are provided from multimodal or sequential acquisitions. As a consequence, a pre-processing step that is called “image registration” is required to achieve data integration. Image registration aims to obtain the best possible spatial correspondence between misaligned datasets. This procedure is also useful to correct distortions induced by magnetic interferences with the acquisition equipment signals or the ones due patient’s involuntary movements such as heartbeat or breathing. The problem can be regarded as finding the …

Instrumental Odour Monitoring System Classification Performance Optimization by Analysis of Different Pattern-Recognition and Feature Extraction Tech…

2020

Instrumental odour monitoring systems (IOMS) are intelligent electronic sensing tools for which the primary application is the generation of odour metrics that are indicators of odour as perceived by human observers. The quality of the odour sensor signal, the mathematical treatment of the acquired data, and the validation of the correlation of the odour metric are key topics to control in order to ensure a robust and reliable measurement. The research presents and discusses the use of different pattern recognition and feature extraction techniques in the elaboration and effectiveness of the odour classification monitoring model (OCMM). The effect of the rise, intermediate, and peak period …

El régimen jurídico de la mediación civil y mercantil en conflictos transfronterizos en españa tras la ley 5/2012, de 6 de julio**Artículo recibido e…

2013

ResumenEl presente artículo analiza en profundidad la regulación que la Ley 5/2012, de 6-7, incorpora de la mediación transfronteriza, abordando diversos aspectos esenciales de ésta. La regulación del acuerdo de sometimiento a mediación, el papel de los mediadores, su formación y reconocimiento de su condición, la eventual ley aplicable al fondo del litigio o la eficacia alcanzada por el acuerdo concluido por las partes son, en este sentido, algunos de los aspectos clave estudiados. El análisis realizado pone de manifiesto el logro intrínseco que la Ley supone y su relevancia a la hora de fomentar el recurso a la institución en España, a la vez, que refleja la necesidad de que la Ley se apl…

Human Enterovirus Group B Viruses Rely on Vimentin Dynamics for Efficient Processing of Viral Nonstructural Proteins.

2019

A virus needs the host cell in order to replicate and produce new progeny viruses. For this, the virus takes over the host cell and modifies it to become a factory for viral proteins. Irrespective of the specific virus family, these proteins can be divided into structural and nonstructural proteins. Structural proteins are the building blocks for the new progeny virions, whereas the nonstructural proteins orchestrate the takeover of the host cell and its functions. Here, we have shown a mechanism that viruses exploit in order to regulate the host cell. We show that viral protein synthesis induces vimentin cages, which promote production of specific viral proteins that eventually control apo…

Analysis of Social Media Impact on Opportunity Recognition. A Social Networks and Entrepreneurial Alertness Mixed Approach

2020

This paper investigates the effects of social media on entrepreneurial opportunity recognition. Combining the internal and external approaches of opportunity recognition, the study analyzes how social media influences the entrepreneurs in discovering new entrepreneurial opportunities. Structural equation modeling was used in this study, using the variance-based partial least squares (PLS)&ndash

Mesure du déficit de reconnaissance des émotions faciales dans la schizophrénie. Étude préliminaire du test de reconnaissance des émotions faciales (…

2015

Resume L’alteration de la cognition sociale associee a la schizophrenie, dont fait partie la perception des emotions faciales, a fait l’objet d’une recente meta-analyse qui a revele son impact majeur sur l’insertion sociale et professionnelle. Or l’utilisation de programmes de remediation cognitive portant sur le traitement des emotions faciales est freinee par un manque d’outil permettant d’identifier et de quantifier les troubles pour un sujet donne. Le test de reconnaissance des emotions faciales (TREF) permet d’evaluer la capacite a reconnaitre 6 emotions universelles (joie, colere, tristesse, peur, degout et mepris), presentees a neuf intensites d’expression s’etalant de 20 % a 100 %. …

Visual word recognition in fluent and dysfluent readers in the transparent Finnish orthography

Sublexical effects on eye movements during repeated reading of words and pseudowords in Finnish

2011

The role of different orthographic units (letters, syllables, words) in reading of orthographically transparent Finnish language was studied by independently manipulating the number of letters (NoL) and syllables (NoS) in words and pseudowords and by recording eye movements during repeated reading aloud of these items. Fluent adult readers showed evidence for using larger orthographic units in (pseudo)word recoding, whereas dysfluent children seem to be stuck in a letter-based decoding strategy, as lexicality and item repetition decreased the NoL effect only among adult readers. The NoS manipulation produced weak repetition effects in both groups. However, dysfluent children showed evidence…
