We report on the modeling of the dynamics of confined lipid membranes. We derive a thin film model in the lubrication limit which describes an inextensible liquid membrane with bending rigidity confined between two adhesive walls. The resulting equations share similarities with the Swift-Hohenberg model. However, inextensibility is enforced by a time-dependent nonlocal tension. Depending on the excess membrane area available in the system, three different dynamical regimes, denoted as A, B and C, are found from the numerical solution of the model. In regime A, membranes with small excess area form flat adhesion domains and freeze. Such freezing is interpreted by means of an effective model for curvature-driven domain wall motion. The nonlocal membrane tension tends to a negative value corresponding to the linear stability threshold of flat domain walls in the Swift-Hohenberg equation. In regime B, membranes with intermediate excess areas exhibit endless coarsening with coexistence of flat adhesion domains and wrinkle domains. The tension tends to the nonlinear stability threshold of flat domain walls in the Swift-Hohenberg equation. The fraction of the system covered by the wrinkle phase increases linearly with the excess area in regime B. In regime C, membranes with large excess area are completely covered by a frozen labyrinthine pattern of wrinkles. As the excess area is increased, the tension increases and the wavelength of the wrinkles decreases. For large membrane area, there is a crossover to a regime where the extrema of the wrinkles are in contact with the walls. In all regimes after an initial transient, robust localised structures form, leading to an exact conservation of the number of adhesion domains. arXiv:1808.00316v1 [cond-mat.soft] 1 Aug 2018

RESUMENLos obispos cronistas Rodrigo Jiménez de Rada y Lucas de Tuy, son las dos principales fuentes latinas para los investigadores del pensamiento político de la España del siglo XIII, de la intervención de Alfonso VIII en la fundación de las universidades de Palencia y Salamanca. Su relato debe examinarse teniendo muy en cuenta los presupuestos teóricos propios de la Realeza sapiencial. Hay una teología política, que pudo ejercer su influencia en el hipotético caso de que el monarca castellano hubiera sido realmente un institutor scholarum y en el caso de que todo fuera un mero discurso. Estas imágenes sapienciales de la Realeza castellana, insertas en el mito «proto-nacional» neogótico, representaronun salto cualitativo en la configuración de una plataforma legitimadora para las aspiraciones de la Realeza castellana, muy en la línea de lo que se estaba escribiendo en el Reino de Francia en esos mismos años. La crónica de Guillaume de Nangis fue un ejemplo sobresaliente.El arquetipo político del Rex sapiens y su proyección en el campo semántico de la renovatio gothorum o la translatio studii, temas importados del pensamiento romanista de los teóricos del Imperio, fueron un lugar de referencia fundamental para comprender el pensamiento político hispano del siglo XIII y para situar en su contexto historiográfico correcto los datos de los cronistas áulicos sobre la iniciativa regia en la fundación de los studia generalia.PALABRAS CLAVE: Universidades medievales, crónicas latinas, obispos, realeza sapiencial Hispania Sacra, LXII 126, julio-diciembre 2010, 491-512, ISSN: 0018-215-X * Este artículo se enmarca en el proyecto de investigación «Legitimación del poder, corrientes religiosas y prácticas de piedad en la Corona de Castilla, siglos XII-XV», Ministerio de Ciencia e Innovación (HAR2008-04696/HIST). REX INSTITUTOR SCHOLARUM: SAPIENTIAL KINGSHIP IN THE LEONESE-CASTILIAN CHRONICLES AND THE ORIGINSOF THE UNIVERSITY OF PALENCIA ABSTRACT Rodrigo Jiménez de Rada and Lucas de Tuy discourse on kingship is the most relevant Latin source available for scholars who deal with political ideology in the Spanish Thirteenth Century. The two chroniclers' narrative of Alfonso VIII's role in the foundation of the universities of Palencia and Salamnca should be analyzed taking into account the topos of Sapiential Kingship. This political theology was influential in any way, even if it were just a rethorical piece in praise of the Castilian King.These sapiential images of Kingship, being part of the proto-national Neo-gothic myth, were an enrichment of the Castilian political discourse as a new source of legitimation of power. The same narrative was being deployed by chroniclers in Thirteenth Century France, like the Chronicle of Guillaume de Nangis.The Rex sapiens political archetype, linked to Roman and Imperial themes as important as the renovatio gothorum or the translatio studii, is a key factor not only for a better understanding of Thirteenth Century Spanish Political Thought but also for a better contextualization of the ...

“…In assuming the theatrical metaphor, this historiographical system makes it possible not only to reinstate the actual time-frame of architecture, from drawing to construction, but also to resituate the architect in the collective scenes of his work (traversed by the figures of Eugène Beaudouin, Jean Prouvé, Vladimir Bodiansky, Henri Sellier, and others) ; a (hi)story, when all is said and done, which "deals with a man and only talks about his day and age insofar as this helps to shed light upon him." 3 …”
