The oral corpora in Catalan and research into casual Catalan: the corpora of conversation and functional varieties of the Corpus de Català Contempora…
2020
Aquest treball pretén exposar el conjunt de corpus i de recerques que s’han elaborat al llarg de diferents projectes promoguts amb l’objectiu de constituir corpus representatius del català corrent (sobretot oral i col·loquial). Els projectes a què es fa referència (VARCOM i PRAGMAESTIL) s’han dut a terme des de final del segle XX i des de la Universitat de Barcelona, més en concret amb la feina desenvolupada per diferents subgrups del Grup d’Estudi de la Variació (GEV-UB), en particular pel Grup d’Estudis de Pragmàtica i Anàlisi del Discurs (GrEPAD). El treball revisa en especial un corpus oral de conversa col·loquial (COC, 2002), un corpus oral de registres (COR, 2004) i un corpus oral aud…
Gagner la guerre des idées : Publius et la nature du républicanisme
2010
This text deals with the specificities of Publius rationale under both the time and the electoral constraints of the ratification debates. Far from being concerned with idle intellectual speculation, the authors of the Federalist Papers faced a political context that was so hostile to their views that the imperative for them was to create legitimacy for their proposal. Publius thus adjusted his views so that the new constitution would be constantly highlighted as an “elective” system where the content of “republicanism” was both altered and improved. His innovative ideas have nonetheless a limit in that they take the form of a “political recipe”—meant to answer specific objections. This for…
An “Objectivists” Anthology: from Manifesto to Tradition
2009
Il s’agit dans cet article de présenter An “Objectivists” Anthology (1932) du poète américain Louis Zukofsky en évaluant l’aspect polémique du discours qui le définit, et ce d’abord au regard de son évolution en tant que projet éditorial (1931-32). Ensuite sera examiné le parcours critique de cette anthologie dans la poésie américaine au vingtième siècle : entre site de marginalisation dans les années trente et l’émergence d’une tradition du retour à l’avant-garde dans les années soixante-dix. Dans quelle mesure la continuité d’une écriture « objectiviste » ne se révèle-t-elle pas comme modèle dans la pratique contemporaine ? Enfin, à supposer que les caractéristiques rhétoriques de l’antho…
L'orientation : que nous dit la comparaison avec les USA ?

Chiral Oxazolidine Complexes Derived from Phenolic Schiff Bases
2020
Schiff bases derived from pyridyl- or salicyl-aldehydes and aminoalcohols can evolve to heterocyclic oxazolidines, which in the presence of cations allow the formation of uncommon coordination compounds. In this work, we report new NiII and mixed valence MnII/ MnIV complexes derived from pyridyl oxazolidines and the unprecedented characterization of enantiomerically pure oxazolidines derived from the condensation of o-vanillin with phenylglycinol in the presence of NiII cations. The different reactivity of the pyridinic or phenolic Schiff bases has been compared, and the new systems have been structurally, optically, and magnetically characterized.
Domain structure of epitaxial SrRuO3 thin films
2005
Growth of multidomains in epitaxial thin-film oxides is known to have a detrimental effect on some functional properties, and, thus, efforts are done to suppress them. It is commonly accepted that optimal properties of the metallic and ferromagnetic $\mathrm{SrRu}{\mathrm{O}}_{3}$ (SRO) epitaxies can only be obtained if vicinal $\mathrm{SrTi}{\mathrm{O}}_{3}$ (001) (STO) substrates are used. It is believed that this results from the suppression of multidomain structure in the SRO film. Here we revise this important issue. Nanometric films of SRO have been grown on STO(001) vicinal substrates with miscut $({\ensuremath{\theta}}_{V})$ angles in the $\ensuremath{\sim}0.04\ifmmode^\circ\else\te…

Giant barocaloric effects over a wide temperature range in superionic conductor AgI
2017
Current interest in barocaloric effects has been stimulated by the discovery that these pressure-driven thermal changes can be giant near ferroic phase transitions in materials that display magnetic or electrical order. Here we demonstrate giant inverse barocaloric effects in the solid electrolyte AgI, near its superionic phase transition at ~420 K. Over a wide range of temperatures, hydrostatic pressure changes of 2.5 kbar yield large and reversible barocaloric effects, resulting in large values of refrigerant capacity. Moreover, the peak values of isothermal entropy change (60 J K−1 kg−1 or 0.34 J K−1 cm−3) and adiabatic temperature changes (18 K), which we identify for a starting tempera…
Measurement of the mass and lifetime of the Ω(−)(b) baryon
2016
A proton-proton collision data sample, corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at $\sqrt{s}=7$ and 8 TeV, is used to reconstruct $63\pm9$ $\Omega_b^-\to\Omega_c^0\pi^-$, $\Omega_c^0\to pK^-K^-\pi^+$ decays. Using the $\Xi_b^-\to\Xi_c^0\pi^-$, $\Xi_c^0\to pK^-K^-\pi^+$ decay mode for calibration, the lifetime ratio and absolute lifetime of the $\Omega_b^-$ baryon are measured to be \begin{align*} \frac{\tau_{\Omega_b^-}}{\tau_{\Xi_b^-}} &= 1.11\pm0.16\pm0.03, \\ \tau_{\Omega_b^-} &= 1.78\pm0.26\pm0.05\pm0.06~{\rm ps}, \end{align*} where the uncertainties are statistical, systematic and from the calibration mode (for $\tau_{\Omega_b^-}$ only). A measurement …
Pulsed-field studies of the magnetization reversal in molecular nanomagnets
2004
We report experimental studies of crystals of Mn12 molecular magnetic clusters in pulsed magnetic fields with sweep rates up to 4x10^3 T/s. The steps in the magnetization curve are observed at fields that are shifted with respect to the resonant field values. The shift systematically increases as the rate of the field sweep goes up. These data are consistent with the theory of the collective dipolar relaxation in molecular magnets.
