Recursos rítmicos utilizados por Tigran Hamasyan en la obra Out of the Grid

Tigran Hamasyan is an Armenian Pianist whose music comes from a wide variety of sources that includes styles such as jazz, classical music, Armenian folk, rock, among others. Due to this richness, his music applies various complex musical resources. In this work we will focus on his rhythmic approach to music by analyzing his work “Out of the Grid”...Tigran Hamasyan es un pianista de origen armenio cuya música se nutre de una gran variedad de fuentes que abarcan estilos como jazz, música clásica, folklore armenio, rock entre otros. Su propuesta musical, al ser muy rica en influencias utiliza una amplia gama de recursos musicales..

Comparación vocal e instrumental de los solos ejecutados por Paul Desmond, Al Jarreau y María João sobre la obra Take Five

In this project, we will focus on analyzing three very important interpreters in the musical field, especially in improvisation. Parts of each solo will be transcribed, and the most relevant sections will be taken into account as tools for their respective explanation. In the first place, we will have a brief review of saxophonist Paul Desmond and vocalists Al Jarreau and María João. We will start with the exploration of each phrase, section, dynamics, articulations, etc., with the intention of studying in greater depth the rhythmic and melodic densities...En este proyecto, nos centraremos en analizar a tres intérpretes muy importantes en el campo musical, especialmente en la improvisación. Se transcribirán partes de cada solo y se tomarán en cuenta las secciones más relevantes como herramientas para su respectiva explicación. En primer lugar, tendremos una pequeña reseña del saxofonista Paul Desmond y los vocalistas Al Jarreau y María João. Partiremos con la exploración de cada frase, sección, dinámicas, articulaciones etc., con la intención de estudiar de manera más profunda las densidades rítmicas y melódicas..

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.

Tras los pasos de la Sílfide. Imaginarios españoles del ballet romántico a la danza moderna

La publicación que tiene la persona lectora entre sus manos realiza un recorrido de cien años de historia de la danza, un camino que toma como punto de partida la cultura visual del Romanticismo y que se ramifica fuera del ámbito geográfico de nuestro país, analizando los rasgos que definen y construyen la danza española y cómo estos se difundieron en los bailes en el extranjero.Las investigaciones contenidas en este libro son resultado del proyecto Tras los pasos de la Sílfide. Una historia de la danza en España, 1836-1936 (PGC2018-093710-A-I00)Peer reviewe
