Transition-edge sensors for particle-induced X-ray emission spectrometry
2018
A transition-edge sensor array has been applied to particle-induced X-ray emission. We have characterized the detector for quantitative analysis and obtained minimum detection limit over two orders of magnitude better compared to a silicon drift detector. We have also studied chemical effects in analysis of Ti, TiO2 and TiN using proton and heavy ion beams. A chemical shift for TiO2 was observed in proton measurements, and relative multiple ionization X-ray satellite line intensities changed between metallic Ti and other compounds with heavy ions. Detection of low energy X-rays down to 0.5 keV was achieved by installing a polycapillary lens in front of the transition-edge sensor array in ex…
Tout savoir sur le treat and extend : organisation et optimisation. Les Cahiers d'Ophtalmologie
2019
La dégénérescence maculaire liée à l’âge (DMLA) est actuellement la première cause de handicap visuel dans les pays développés chez les plus de 50 ans. Elle touche en effet environ 8% de la population française et plus de 25% des plus de 75 ans. La constatation d’une insuffisance de traitement lors d’un régime « réactif » a poussé les cliniciens à proposer d’autres types de régimes. Le « Treat and Extend » (T&E) est né de la volonté d’adapter les intervalles de retraitement des patients pour une prise en charge plus personnalisée.
Preferències sensorials i ús autopercebut d’estratègies en l’aprenentatge de les ciències dels estudiants de secundària: anàlisis i proposta instrucc…
2019
Las diferencias individuales de los estudiantes de secundaria y los factores con influencia en el aprendizaje de las ciencias fueron el tema principal de esta Tesis. Esta investigación se centró en la descripción y el análisis de las preferencias sensoriales del estudiante y la conexión entre ellos y los recursos instruccionales utilizados en las secuencias didácticas usadas en el aprendizaje de las ciencias en secundaria. Existe una posible explicación sobre el beneficio de los estudiantes mediante el uso de ciertos materiales de aprendizaje. El aprendizaje multimedia definido por Mayer (2005) establecía que el cerebro humano asigna diferentes recursos cognitivos para la recepción de difer…
Seeing Gravity: Gait Adaptations to Visual and Physical Inclines – A Virtual Reality Study
2020
Using advanced virtual reality technology, we demonstrate that exposure to virtual inclinations visually simulating inclined walking induces gait modulations in a manner consistent with expected gravitational forces (i.e., acting upon a free body), suggesting vision-based perception of gravity. The force of gravity critically impacts the regulation of our movements. However, how humans perceive and incorporate gravity into locomotion is not well understood. In this study, we introduce a novel paradigm for exposing humans to incongruent sensory information under conditions constrained by distinct gravitational effects, facilitating analysis of the consistency of human locomotion with expecte…
Tapping Doesn't Help : Synchronized Self-Motion and Judgments of Musical Tempo
2019
For both musicians and music psychologists, beat rate (BPM) has often been regarded as a transparent measure of musical speed or tempo, yet recent research has shown that tempo is more than just BPM. In a previous study, London, Burger, Thompson, and Toiviainen (Acta Psychologica, 164, 70–80, 2016) presented participants with original as well as “time-stretched” versions of classic R&B songs; time stretching slows down or speeds up a recording without changing its pitch or timbre. In that study we discovered a tempo anchoring effect (TAE): Although relative tempo judgments (original vs. time-stretched versions of the same song) were correct, they were at odds with BPM rates of each stimulus…

Does Physical Activity Improve Inhibition in Kindergarteners? A Pilot Study
2022
Substantial empirical evidence supports the positive effects of physical activity (PA) on executive functions, but not all forms of physical activity benefit equally. Among kindergarteners, cognitively-engaging exercise seems to more strongly effect EF than simple exercise. We aimed to investigate several qualitatively different exercise formats on kindergarteners' inhibition. Participants were 75 children (M age = 68.1 months), recruited from 14 classrooms of three kindergarten schools. They were randomly assigned to three groups: control group, free play group (non-cognitively-engaging PA), and an intervention group (cognitively-engaging PA). The intervention group performed 18 sessions …
Sensory analysis integrated by palynological and physicochemical determinations plays a key role in differentiating unifloral honeys of similar botan…
2015
Summary Myrtaceae honeys produced in Sierra Morena (southern Spain, Andalusia) are obtained from both Eucalyptus camaldulensis and Myrtus communis, and honeys can be easily confused when classified as they come from the same botanical family. The characterisation was intended on the basis of their physicochemical, sensory and palynological properties. Cluster analysis (CA) and principal component analysis (PCA) allowed us to make a distinction between two honey profiles. The first one corresponds to the European sensory profile described for Eucalyptus unifloral honeys. The second profile, which sensory characteristics are absolutely different, has not been previously described. Classificat…
