Salvador de Madariaga se erige como uno de los pensadores del siglo XX que más tiempo y esfuerzo dedicó a la idea de España, de ser español y a las identidades europeístas, muchas veces ligadas a su concepción del Quijote. Una de sus novelas menos estudiadas, Sanco Panco (1964), denominada «novela-fantasía» por él mismo, fue construida como parodia del régimen franquista e imitación del estilo cervantino. Siguiendo el marco teórico de la fantasía y lo maravilloso de David Roas (2001, 2008), tendremos en cuenta los conceptos de humor, especialmente el lingüístico y el poliglotismo madariaguesco. El escritor hace especial hincapié en la visión en algunos estereotipos nacionales dentro del espacio de la guerra fría y la dictadura franquista, usando para ello la parodia lingüística, tan fácil para el Madariaga trilingüe y diplomático, buen conocedor de las diversas nacionalidades que intervinieron en la política internacional de los años cincuenta y sesenta del pasado siglo. Salvador de Madariaga stands as one of the 20th-century thinkers who devoted the most time and effort to reflecting on Spain, Spanish identity, and Europeanist identities, often linked to his interpretation of Don Quixote. One of his lesser-studied novels, Sanco Panco (1964)—which he called a «fantasy-novel»—was crafted as both a parody of the Franco regime and an imitation of Cervantes’ style. Drawing on David Roas’s theoretical framework on fantasy and the marvelous (2001, 2008), this study considers humor—especially linguistic humor—and Madariaga’s polyglotism. The author emphasizes national stereotypes within the context of the Cold War and Franco’s dictatorship, using linguistic parody, a tool easily wielded by the trilingual diplomat and writer, well-versed in the various national identities that shaped international politics in the 1950s and 60s.

La dedicación de José Ares Montes, Fidelino de Figueiredo, María Fernanda Abreu o Silvia Cobelo, entre otros, a la presencia de Cervantes en Portugal se puede escindir en varias vertientes, a saber: la influencia de la obra cervantina en autores portugueses y sus obras ‒analizados comparativamente‒, la presencia de Portugal en la vida y obra de Miguel de Cervantes ‒que da lustre y prestigio a Lisboa por su aparición en el Persiles‒, las traducciones al portugués ‒tardías, pero relevantes‒ y, en fin, la divulgación del universo cervantino en Portugal y en portugués. No obstante, siempre quedan en tierras lusitanas nuevos lectores avisados por estudiar, miradas críticas a las nuevas traducciones y vestigios de la divulgación de la vida y obra cervantina por desvelar en el Portugal contemporáneo. Palabras clave: Cervantes, recepción, Portugal, traducción, ensayo.   Abstract: The dedication of José Ares Montes, Fidelino de Figueiredo, María Fernanda Abreu and Silvia Cobelo, among others, to the presence of Cervantes in Portugal can be divided in several branches such as: the influence of Cervantes in Portuguese au­thors works ‒comparatively analyzed‒, the presence of Portugal in the life and work of Miguel de Cervantes ‒That gives prestige and highlights Lisbon due to its appearance at Persiles‒, the translations into Portuguese ‒delayed but relevant‒ and last, but not least, the promotion of the Cervantes universe in Portugal written in Portuguese. However, in contemporary Portugal there will always be the need to unveil learned readers waiting to be studied, different critical looks on new translations and traces of the life and work of Cervantes. Keywords: Cervantes, reception, Portugal, translation, essay.

Ferdinand VI and Barbara of Bragança, important patrons of the music and arts in Spain, created the most ambitious court concerning cultural entertainment in the European eighteenth century. The localization in the district archive of six editions of put-on-music theatre pieces between 1747 and 1757, and dedicated to the Queen, allows us to develop a historical and literary study on one of them, which originally begins in medieval times but that becomes relevant in the Spanish Baroque period thanks to Lope de Vega, Góngora and Cervantes, among others. Angélica y Meodoro, in Ferdinand VI's court, is carried out by Pietro Metastasio (1705-1782), author of several opera librettos, and by Carlo Broschi Farinelli (1698-1782) or, as he used to sign in his Spanish compositions, Carlos Brosqui Farinelo, the singer who contributed to the success of these plays in the eighteenth century. Hemos vaciado, entonces, el fondo español del archivo distrital y podemos constatar que, a pesar de la abundancia incontestable de volúmenes españoles o bilingües -cerca de ciento cuarenta-, la mayor parte son de tipo pío, por lo que la aparición de esta colección de seis óperas teatrales bilingües es un hallazgo extraño en este mar de libros religiosos.

We present new spectroscopic data for Gaia DR3 2309499817384726016 (WD0008-350A) and its two wide, co-moving, low-mass companions. We confirm the white dwarf is a hydrogen-rich DA, with T\\(_ eff\\)=6200\\(\\)90~K and a mass of 0.63\\(\\)0.03~M\\(\\), close to that of the average white dwarf. Near-infrared spectra of the two stellar companions to WD0008-350A reveal that the inner companion is an M dwarf, exhibiting a spectral type of M8. Furthermore, the outer companion is identified as a possible M6 + M9 binary. This paper examines the evidence which suggests the system may be quadruple.

We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and the infrared. Through this process, we identified fifty-one previously unrecognized systems with candidate ultracool companions. Thirty-one of these systems are resolved in at least one catalog, and all but six are confirmed as co-moving companions via common proper motion and consistent parallax measurements (when available). We have followed up four co-moving companions with near-infrared spectroscopy and confirm their ultracool nature. The remaining twenty candidates are unresolved, but show clear signs of infrared excess which is most likely due to the presence of a cold, low-mass companion or a dusty circumstellar disk. Three of these unresolved systems have existing optical spectra that clearly show the presence of a cool stellar companion to the white dwarf primary via spectral decomposition. These new discoveries, along with our age estimates for the primary white dwarfs, will serve as valuable benchmark systems for future characterization of ultracool dwarfs.

We present three new brown dwarf spectral binary candidates: CWISE J072708.09\\(-\\)360729.2, CWISE J103604.84\\(-\\)514424.4, and CWISE J134446.62\\(-\\)732053.9, discovered by citizen scientists through the Backyard Worlds: Planet 9 project. Follow-up near-infrared spectroscopy shows that each of these objects is poorly fit by a single near-infrared standard. We constructed binary templates and found significantly better fits, with component types of L7+T4 for CWISE J072708.09\\(-\\)360729.2, L7+T4 for CWISE J103604.84\\(-\\)514424.4, and L7+T7 for CWISE J134446.62\\(-\\)732053.9. However, further investigation of available spectroscopic indices for evidence of binarity and large amplitude variability suggests that CWISE J072708.09\\(-\\)360729.2 may instead be a strong variability candidate. Our analysis offers tentative evidence and characterization of these peculiar brown dwarf sources, emphasizing their value as promising targets for future high-resolution imaging or photometric variability studies.

We have used the UKIRT Hemisphere Survey (UHS) combined with the UKIDSS Galactic Cluster Survey (GCS), the UKIDSS Galactic Plane Survey (GPS), and the CatWISE2020 catalog to search for new substellar members of the nearest open cluster to the Sun, the Hyades. Eight new substellar Hyades candidate members were identified and observed with the Gemini/GNIRS near-infrared spectrograph. All eight objects are confirmed as brown dwarfs with spectral types ranging from L6 to T5, with two objects showing signs of spectral binarity and/or variability. A kinematic analysis demonstrates that all eight new discoveries likely belong to the Hyades cluster, with future radial velocity and parallax measurements needed to confirm their membership. CWISE J042356.23\\(+\\)130414.3, with a spectral type of T5, would be the coldest ($T_{\\rm eff}$$\\approx\\(1100 K) and lowest-mass (\\)M$$\\approx\\(30 \\)M_{\\rm Jup}$) free-floating member of the Hyades yet discovered. We further find that high-probability substellar Hyades members from this work and previous studies have redder near-infrared colors than field-age brown dwarfs, potentially due to lower surface gravities and super-solar metallicities.

The ability to couple a solitary spin to high-frequency motion is a crucial advancement for a range of applications, including quantum sensing, intermediate and long-distance spin-spin coupling, and quantum information processing. Although proposed theoretically over a decade ago, experimental demonstrations have remained elusive. Here we report the observation of spin-mechanical coupling in a carbon nanotube device. We demonstrate this coupling in two configurations: off-resonant, with spin and mechanics excited by separate tones, and resonant, driven by a single tone. The coupling manifests as a shift and broadening of the electric dipole spin resonance (EDSR), respectively. Our theoretical model, which accounts for the tensor character of the coupling and mechanical non-linearity, reproduces the data with very good agreement. Our results demonstrate a previously unobserved spin-mechanical coupling, offering versatile tools for exploring macroscopic quantum phenomena, quantum thermodynamics, and quantum simulation. The interaction between single spins and mechanical motion has been demonstrated in solid-state platforms, though limited to low-frequency modes. Here, the authors realize the coupling between an electron spin in a double quantum dot and a high-frequency mechanical mode in a suspended carbon nanotube device.

Time is a crucial parameter in the assessment of comorbidities in population-based studies, as it permits to identify more complex disease patterns apart from the pairwise disease associations. So far, it has been, either, completely ignored or only, taken into account by assessing the temporal directionality of identified comorbidity pairs. In this work, a novel time-analysis framework is presented for large-scale comorbidity studies. The disease-history vectors of patients of a regional Spanish health dataset are represented as time sequences of ordered disease diagnoses. Statistically significant pairwise disease associations are identified and their temporal directionality is assessed. Subsequently, an unsupervised clustering algorithm, based on Dynamic Time Warping, is applied on the common disease trajectories in order to group them according to the temporal patterns that they share. The proposed methodology for the temporal assessment of such trajectories could serve as the preliminary basis of a disease prediction system.
