The Blog is Dead, Long Live the Blog! Analysis of Blogs on Spanish Radio Stations

Index Comunicación, 2015
Blogs linked to the various media channels have changed considerably over the last five years as a direct result of the growth of the social networks, and they now occupy a secondary position, at least in terms of visibility.

Radio universitaria: trabajo en red como imperativo

Edmetic: Revista de Educación Mediática y TIC, 2014
Trabajo en red es un concepto clave en la radio universitaria, tanto desde el punto de vista individual como del colectivo. A través de dos estudios de caso, enfocados en la radio universitaria de Italia y de Colombia, este artículo muestra cómo el ...

Commissioning of Halcyon enhanced leaf model in the Eclipse treatment planning system: Focus on simple slit fields and VMAT dose calculation

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The dual‐layer multileaf collimator (MLC) in Halcyon adds complexities to the dose calculation process owing to the variability of dosimetric characteristics with leaf motion. Recently, an enhanced leaf model (ELM) was developed to refine the MLC model in the Eclipse treatment planning system. This study investigates the performance of

On the Relation Between Radio and Non-Radio Elliptical Galaxies [PDF]

arXiv, 2000
Empirical evidence suggests that elliptical galaxies hosting a radio source may not be different from normal non-radio ellipticals. To test this possibility, we use Monte Carlo simulations to reproduce the distribution of radio galaxies in the radio-optical luminosity plane. The input parameters of the simulation are the optical luminosity function (LF)

Closing the gap in plan quality: Leveraging deep‐learning dose prediction for adaptive radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Balancing quality and efficiency has been a challenge for online adaptive therapy. Most systems start the online re‐optimization with the original planning goals. While some systems allow planners to modify the planning goals, achieving a high‐quality plan within time constraints remains a common barrier.

The Evolution of Diffuse Radio Sources in Galaxy Clusters

, 2003
We investigate the evolution and number distribution of radio halos in galaxy clusters. Without re-acceleration or regeneration, the relativistic electrons responsible for the diffuse radio emission will lose their energy via inverse-Compton and ...

Bone‐wise rigid registration of femur, tibia, and fibula for the tracking of temporal changes

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Multiple myeloma (MM) induces temporal alterations in bone structure, such as osteolytic bone lesions, which are challenging to identify through manual image interpretation. The large variation in radiologists' assessments, even at expert centers, further complicates diagnosis.

Nuevos hábitos de los jóvenes españoles y tendencias de futuro en el consumo de radio y televisión

Historia y Comunicación Social, 2014
La radio y la televisión son los mass media que, por detrás de Internet, cuentan con una mayor penetración entre los jóvenes de hoy. Y es que a pesar del amplio abanico de opciones que la Red pone a disposición de la audiencia juvenil para disfrutar de ...

Radio U-Net: a convolutional neural network to detect diffuse radio sources in galaxy clusters and beyond [PDF]

arXiv
The forthcoming generation of radio telescope arrays promises significant advancements in sensitivity and resolution, enabling the identification and characterization of many new faint and diffuse radio sources. Conventional manual cataloging methodologies are anticipated to be insufficient to exploit the capabilities of new radio surveys.
