l acceso cada vez más generalizado a las tecnologías digitales y el aumento de la capacidad de procesamiento de información de los dispositivos electrónicos ha provocado que, en los años más recientes, haya resurgido un interés masificado en las llamadas Inteligencias Artificiales (AI). A la luz de los últimos avances en este campo, ha cobrado fuer...

La aportación teórica y filosófica de Mikhail Bakhtin ha propuesto como punto de partida para el análisis de la novela y otros textos, el concepto de «dialogis- mo», desde su obra Dialogic Imagination, publicada en Moscú en 1975 y traducida a la lengua inglesa por la Universidad de Texas en Austin en 1981. En esta se abordan temas del análisis como...

CONTEXT: Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains identical astrometric results). The reference frame is defined by the positions and proper motions at epoch 2016.0 for a specific set of extraga...

La semiótica, particularmente durante las últimas décadas, se ha ido revelando como una disciplina por demás pertinente en el análisis de los fenómenos culturales. Debido a la amplitud de su campo de estudio -la cultura tomada globalmente como un universo de sentido-, tiene inevitablemente una vocación hacia la interdisciplinariedad: son muchos...
Book
Comunicación y discursos cotidianos es un volumen que reúne trabajos en los que, desde distintos enfoques teóricos y metodológicos, se analizan fenómenos de la lengua, la comunicación y, en general, de la cultura, que ocurren todos los días a nuestro alrededor. En cada texto se muestran voces diversas, desde las que históricamente han sido marginad...

Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims: We present the Gaia Science Alerts project, which has been in operation since 1 June 2016. We describe the system which has been developed to enable the discovery and publicat...

The Gaia Early Data Release 3 (Gaia EDR3) contains results derived from 78 billion individual field-of-view transits of 2.5 billion sources collected by the European Space Agency's Gaia mission during its first 34 months of continuous scanning of the sky. We describe the input data, which have the form of onboard detections, and the modeling and pr...

Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in the magnitude range G = 3 to 21 based on observations collected by the European Space Agency Gaia satellite during the first 34 months of its operational phase. We describe the input data, the models, and the processing used for the astrometric content of Gaia EDR3,...

Se muestra cómo determinados elementos textuales, concretamente, un sintagma fijo, deconstruido dentro del poema de Miguel Hernández “El niño yuntero”, parte de la colección El viento del pueblo (1937), posee una carga semántica tal que la proyecta a lo largo de todas las estrofas. En este sentido, podemos considerarlo como un signo hegemónico. Ade...

En este artículo se ponen de relieve algunas dificultades que a lo largo del tiempo se han tenido para delimitar la noción de ‘texto’. Su uso frecuente en los ámbitos de la crítica literaria, de la lingüística, de la semiótica… pudiera remitirnos a la idea de que existe una concepción homogénea. Sin embargo, lejos de esto, dentro de una misma disci...

En las últimas décadas, la Relación de Michoacán (que escribiera el fraile franciscano Jerónimo de Alcalá, cerca del año 1540) ha recibido una creciente atención. Ya no resulta extraño decir que, en varios textos de origen indígena pertenecientes a la actual América Latina, se pone en duda la autenticidad y se destaca la manipulación de la informac...

We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs, depending in particular on stellar population selections. We do not aim here for completeness in terms of types of stars or stellar evolutionary aspects. Instead, we have chosen several ill...

Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the magnitude range 3 to 21 based on observations collected by the European Space Agency Gaia satellite during the first 22 months of its operational phase. We describe the input data, models, and processing used for the astrometric content of Gaia DR2, and the validation o...

Context. The second Gaia data release ( Gaia DR2) contains high-precision positions, parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for 7.2 million stars brighter than G RVS = 12 mag. Both samples provide a full sky coverage. Aims. To illustrate the potential of Gaia DR2, we provide a first look at the ki...

All text is formed by transcription and deconstruction of fragments from other texts-source, sayings, historical events, ideologies, even textual elements whose code is different from text-receiver. This phenomenon, in general, is known as intertextuality, which, at the same time, operates as an interpretant that provides keys of interpretation on...

Bajo las líneas de la sociosemiótica, el análisis de la canción María Pilar, de Teresa Parodi, nos presentará determinados rastros discursivos relativos al fenómeno de los desaparecidos por las dictaduras de los años setenta y ochenta en Sudamérica. Dichos rastros discursivos, en algunos casos, son comunes en la lucha social por la conformación de...

Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release 1 (DR1) as part of the Tycho-Gaia Astrometric Solution (TGAS). In order to test these first parallax measurements of the primary standard candles of the cosmological dis...

Context. The first Gaia Data Release contains the Tycho - Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using H ipparcos and Tycho-2 positions in 1991.25 as prior information. Aims. We investigate the scientific potential and...

Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations d...

Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during the first 14 months of its operational phase. We give a brief overview of the astrometric content of the data release and of the model assumptions, data processing, and v...

Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by European industry. The involvement of the scientific...
