Stable spirocyclic neutral radicals: aluminum and gallium boraamidinates
2005
Stable dark red (M = Al) or dark green (M = Ga) neutral radicals {[PhB(μ-NtBu)2]2M}˙ are obtained by the oxidation of their corresponding anions with iodine, and EPR spectra supported by DFT calculations show that the spin density is equally delocalized over all four nitrogen atoms in these spiroconjugated systems. peerReviewed

The Translation of Chinese Medical Terms into English. Linguistic Considerations on the Language of TCM
2009
The growing diffusion of TCM (Traditional Chinese Medicine) in the Western world on the one hand, and the major role of English as the language of scientific communication and international exchange on the other, have led to the need for accuracy and standardization in the English terminology of Chinese medical concepts. The complexity of Chinese medical language, not only due to the innumerable quantity of ideograms1, but above all to their correct interpretation and to the philosophical foundations which TCM is based upon, has raised several debates among linguists, translators and physicians. One of the main issues concerns the approach to be adopted in the translation of Chinese terms i…
Pseudospectrum of Reissner-Nordström black holes: Quasinormal mode instability and universality
2021
Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitational waveforms could soon lead to high-precision gravitational spectroscopy, so it is critical to understand if the quasinormal mode spectrum is stable against perturbations. It was recently shown that the pseudospectrum can shed light on the spectral stability of black hole quasinormal modes. We study the pseudospectrum of Reissner-Nordstr\"om spacetimes and we find a spectral instability of scalar and gravitoelectric quasinormal modes in subextremal and extremal black holes, extending similar findings for the Sch…
Spectral properties of X-ray bright variable sources in the Taurus Molecular Cloud
2006
We analyze 19 bright variable X-ray sources detected in the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), in order to characterize the variations with time of their coronal properties and to derive informations on the X-ray emitting structures. We performed time-resolved spectroscopy of the EPIC PN and MOS spectra of the XEST sources, using a model with one or two thermal components, and we used the time evolution of the temperatures and emission measures during the decay phase of flares to derive the size of the flaring loops. The light curves of the selected sources show different types of variability: flares, long-lasting decay or rise through the whole observation, sl…
Spectral analysis of the dipping LMXB system XB 1916-053
2019
Context: XB 1916-053 is a low mass X-ray binary system (LMXB) hosting a neutron star (NS) and showing periodic dips. The spectrum of the persistent emission was modeled with a blackbody component having a temperature between 1.31 and 1.67 keV and with a Comptonization component with an electron temperature of 9.4 keV and a photon index $\Gamma$ between 2.5 and 2.9. The presence of absorption features associated with highly ionized elements suggested the presence of partially ionized plasma in the system. Aims: In this work we performed a study of the spectrum of XB 1916-053, which aims to shed light on the nature of the seed photons that contribute to the Comptonization component. Methods: …

Jorge Lozano e la semiotica della storia

L'intervento esamina pregi e limiti del contributo del semiologo spagnolo Lozano al campo poco battuto - per quanto interessantissimo - della semiotica della storia
Juan Antonio Ruiz-Casaux y su aportación al violonchelo español. Pedagogo, intérprete, restaurador-conservador de Stradivarius y compositor.
2015
En esta investigación se da a conocer la figura de Juan Antonio Ruiz-Casaux y López de Carvajal (1889-1972), ya que se trata de una de las personalidades más importantes de la música española de la primera mitad del s. XX. En la actualidad, no existe información ni documentación relevante acerca de este gran violonchelista español. A través de esta investigación puede conocerse, por primera vez en la historia de la música, la vida y obra del maestro Casaux. Este estudio se centra en cuatro de sus múltiples facetas. La primera la dedicada a su trayectoria como concertista. Su magnitud como intérprete solista le ha encumbrado al grupo de “las tres ces” (Casals-Casaux-Cassadó), así como su act…
