Edición del tratado de paz bilingüe de 1405 entre el Reino de Granada y la Corona de Aragón
2020
El artículo ofrece la edición completa de las dos partes (árabe y aragonesa) de este documento y la traducción al castellano de la parte árabe, de las que hasta ahora no disponíamos. Era necesario realizarlas y ponerlas al alcance de la comunidad científica para tener una base fiable a partir de la que emprender su estudio diplomático y realizar cualquier otro acercamiento de tipo histórico.
IceCube Oscillations: 3 years muon neutrino disappearance data
2015
In the 1990s, Super-Kamiokande’s measurements of atmospheric neutrinos led to the acceptance of the mass-induced oscillation model. As of today, the three mixing angles, the solar mass splitting and the absolute value of the atmospheric mass splitting that control the oscillation phenomenon have been measured. We present a measurement of neutrino oscillations via atmospheric muon neutrino disappearance with three years of data of the completed IceCube neutrino detector. DeepCore, a region of denser instrumentation, enables the detection and reconstruction of atmospheric muon neutrinos between 10 GeV and 100 GeV, where a strong disappearance signal is expected.

New orbital ephemerides for the dipping source 4U 1323-619: Constraining the distance to the source
2016
4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the orbital ephemeris, the orbital period of the system, as well as its derivative to compare the observed luminosity with that predicted by the theory of secular evolution. We took the advantage of about 26 years of X-ray data and grouped the selected observations when close in time. We folded the light curves and used the timing technique, obtaining 12 dip arrival times. We fit the delays of the dip arrival times both with a linear and a quad…
Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934
2006
We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival times of all the events for the orbital (Doppler) effects and performed a timing analysis of the resulting phase delays. In this way we have the possibility to study, for the first time in this class of sources, the spin-up of a millisecond pulsar as a consequence of accretion torques during the X-ray outburst. The accretion torque gives us for the first time an independent estimate of the mass accretion rate onto the neutron star, which can be compared with the observed X-ray luminosity. We also report a revised valu…
Description and phylogenetic relationships of a new species of treefrog of theOsteocephalus buckleyispecies group (Anura: Hylidae)
2020
The Osteocephalus buckleyi species group is widely distributed in primary and secondary forests of the Amazon Basin and Guiana Region. Based on integrative analysis, including morphological and genetic data, we estimate the phylogenetic relationships and species boundaries among populations of the Osteocephalus buckleyi group from the Ecuadorian Amazon, focusing on the O. verruciger-O. cannatellai species complex. Our results uncovered the existence of one confirmed candidate species from Sangay National Park and one unconfirmed candidate species. Here, we describe the new species which is morphologically and ecologically distinct from other Osteocephalus species. The new species is unusual…

Noise Reduction and Gap Filling of fAPAR Time Series Using an Adapted Local Regression Filter
2014
Time series of remotely sensed data are an important source of information for understanding land cover dynamics. In particular, the fraction of absorbed photosynthetic active radiation (fAPAR) is a key variable in the assessment of vegetation primary production over time. However, the fAPAR series derived from polar orbit satellites are not continuous and consistent in space and time. Filtering methods are thus required to fill in gaps and produce high-quality time series. This study proposes an adapted (iteratively reweighted) local regression filter (LOESS) and performs a benchmarking intercomparison with four popular and generally applicable smoothing methods: Double Logistic (DLOG), sm…
Aliens and dragons: purposefully-framed play and non-standard learning methods in teaching evolutionary processes to primary school pupils
2023
Evolutionary processes lie at the base of the entire observable biodiversity, both at present and in the geological past (i.e., in the fossil record). For this reason, the teaching of evolution should receive more recognition than it currently has (e.g., in Poland) and become accurately applied from the early formal education stages onwards. To test the possibility of effective teaching of evolution to primary school pupils, workshops using non-standard learning methods (‘purposefully-framed play’) were organised during childrens’ university (UNIKIDS) courses of one-hour sessions for 33 groups, comprising several to 20 participants, aged 7 to 12. The final task for all participants was to p…
