Las investigaciones arqueológicas de la última década han aportado una coincidente información que empieza a desvelar la riqueza y avatares de la cultura castreña en Asturias durante buena parte del primer milenio a.C. Sin embargo, algunas opiniones, que

La metalurgia del hierro en la Asturias castreña: nuevos datos y estado de la cuestión
Se realiza una revisión de las evidencias de los trabajos siderúrgicos y de los objetos de hierro de los castros asturianos, así como de la relación entre éstos y las posibles zonas de minería.

Multi-resolution internal template cleaning: An application to the Wilkinson Microwave Anisotropy Probe 7-yr polarization data [PDF]
Cosmic microwave background (CMB) radiation data obtained by different experiments contain, besides the desired signal, a superposition of microwave sky contributions.

CMB polarization as a probe of the anomalous nature of the Cold Spot [PDF]
One of the most interesting explanations for the non-Gaussian Cold Spot (CS) detected in the WMAP data by Vielva et al. 2004, is that it arises from the interaction of the CMB radiation with a cosmic texture (Cruz et al. 2007b).

The chiral benzotrithiophene derivative 1 self‐assembles into helical supramolecular polymers whose helicity changes with water content. High water content induces a reversible double stereomutation, while low water content yields a single, stable one. Computational studies show two monomer conformations leading to opposite helices.

We review two powerful methods to test the Gaussianity of the cosmic microwave background (CMB): one based on the distribution of spherical wavelet coefficients and the other on smooth tests of goodness-of-fit.

Gravitationally lensed QSOs in the ISSIS/WSO-UV era
Gravitationally lensed QSOs (GLQs) at redshift z = 1-2 play a key role in understanding the cosmic evolution of the innermost parts of active galaxies (black holes, accretion disks, coronas and internal jets), as well as the structure of galaxies at ...

Improved constraints on primordial non-Gaussianity for the Wilkinson Microwave Anisotropy Probe 5-yr data [PDF]
We present new constraints on the non-linear coupling parameter fnl with the Wilkinson Microwave Anisotropy Probe (WMAP) data. We use an updated method based on the spherical Mexican hat wavelet (SMHW) which provides improved constraints on the fnl ...

En este artículo se dan a conocer las primeras dataciones radiocarbónicas directas para la orfebrería castreña del noroeste de la Península Ibérica, obtenidas a partir de tres muestras procedentes de una masa de fundición y de un lingote plano-convexo de
