Technical, tactical and spatial indicators related to goal scoring in European elite soccer
2020
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
Broglie and Young, visionaries who shed light in the polar topology that grounds our reality: a hypothesis
2020
Una observación matemática que relaciona los patrones fractales y la operación de convolución en el contexto del procesamiento de imágenes digitales interrumpió una investigación que nos lleva a plantear la hipótesis de que el concepto de onda de materia (o dualidad onda-partícula) se encuentra en la dicotomía entre el par débil y un topología fuerte en el ámbito del marco de atractores singulares continuos en ninguna parte diferenciables y el concepto de fotón-solitón de Vigier. Tal inferencia parece ser más evidente en la interpretación de Broglie-Bohm de la mecánica cuántica en el cruce de características locales x globales. De esto se deduce también que la relación de los fenómenos natu…
X-ray emission from the old CTTS MP Muscae
2007
We study the properties of X-ray emitting plasma of MP Mus, an old classical T Tauri star. XMM-Newton/RGS spectra allow us to measure the plasma electron density, which probes whether X-ray emission is produced in the accretion process. X-ray emission from MP Mus originates from high density cool plasma but a hot flaring component is also present, suggesting that both coronal magnetic activity and accretion contribute to the observed X-ray emission. From the soft part of the X-ray emission from MP Mus, mostly produced by plasma heated in the accretion shock, we derive the accretion parameters and the characteristics of the shock-heated plasma.

Recensione a R. Darnton, L’età dell’informazione. Una guida non convenzionale al Settecento
2007
La recensione prende in considerazione gli otto saggi che forniscono al «comune lettore colto» una via d’accesso alla comprensione delle mentalità settecentesca. Un’insolita guida al Settecento, dunque, secolo complesso e multiforme per eccellenza, di cui Darnton intende svelare gli addentellati col mondo contemporaneo.
