Biharmonic obstacle problem: guaranteed and computable error bounds for approximate solutions
2020
The paper is concerned with a free boundary problem generated by the biharmonic operator and an obstacle. The main goal is to deduce a fully guaranteed upper bound of the difference between the exact minimizer u and any function (approximation) from the corresponding energy class (which consists of the functions in $H^2$ satisfying the prescribed boundary conditions and the restrictions stipulated by the obstacle). For this purpose we use the duality method of the calculus of variations and general type error identities earlier derived for a wide class of convex variational problems. By this method, we define a combined primal--dual measure of error. It contains four terms of different natu…
Interactions of membranes with coarse-grain proteins: a comparison
2012
We study the interactions between lipid bilayers and rigid transmembrane proteins by Monte Carlo simulations of generic coarse-grain models. Different popular protein models are considered and compared with each other, and key parameters such as the hydrophobicity and the hydrophobic mismatch are varied systematically. Furthermore, the properties of the membrane are manipulated by applying different tensions. The response of the membrane to the insertion of single proteins is found to be mostly generic and independent of the choice of the protein model. Likewise, the orientational distributions of single proteins depend mainly on the hydrophobic mismatch and the hydrophobicity of the protei…
Relación entre normas generales y normas individuales: un paralelismo entre la Lingüística y la disciplina jurídica en torno al concepto de instituci…
2014
La cientificidad de la disciplinajurídica es usualmente materia de debate. Las particularidades que posee no sonsolo exclusivas de ella sino que en buena medida pueden ser encontradas enotras ‘ciencias’. No obstante, muchos de estos otros conjuntos de conocimientosson considerados científicos aun cuando adolecen de los mismos inconvenientes. Eneste trabajo se realiza un paralelismo entre la ‘Ciencia’ del Derecho y laLingüística. Para tal tarea, se parte de un presupuesto, el cual es queexplorar las semejanzas y diferencias estructurales entre los objetosdisciplinares de la Lingüística y de la ‘Ciencia’ del Derecho es útil a fin decomprender desde una perspectiva distinta ciertos problemas q…
Party autonomy regarding jurisdiction under the property regimes regulations
2021
The main accomplishment of the Property Regimes Regulations lies in their bringing more coherence into the cross-border family law adjudication. In the field of international jurisdiction, they strive to align the competence in couples? patrimony disputes to that in succession and in separation proceedings, or else to align the competence of the courts to the applicable law. These tendencies are clearly visible in the Regulations? provisions on choice of court agreements. Namely, the Regulations allow for such agreements, but severely limit parties? choice and the possible effects of these clauses. When succession or separation proceedings are pending, it is often only possible to institute…

Digital resources in the current journalistic narrative: Uses and limitations of hypertext, multimedia and interactivity
2020
Characterised by its multilingual and multiformat features, the multimedia journalism narrative is shaping a new ‘archaeology of composition’ (Manovich, 2005), also called the ‘new textuality’ (Anichini, 2003). As digital media celebrates its 25th anniversary (Salaverría, 2019), this research aims to examine the current state of the multimedia narrative in journalism. The defining elements of this narrative in the generalist information media have been analysed through the observation of hypertextual, multimedia and interactive resources. The methodology used is content analysis, allowing for both the systemization and description of the predominant parameters through the comparative study …
La Aceptación Familiar y la Conducta Prosocial: el Rol de los Factores de Personalidad en Menores con Medidas de Internamiento Judicial
2021
espanolEn la presente investigacion se analiza la relacion entre el sentimiento de aceptacion familiar y las distintas dimensiones de la conducta prosocial en menores infractores en regimen de internamiento. El interes esta tambien en determinar el rol mediador y moderador que tienen los factores de personalidad (modelo de los “cinco grandes”) en la relacion entre el sentimiento de aceptacion familiar y la conducta prosocial. La muestra esta formada por 162 menores infractores con edades entre los 14 y los 22 anos (M = 17.10, DT = 1.41), con medida judicial de internamiento en centros de la Comunidad Autonoma de Madrid (Espana). Los resultados obtenidos indican que no hay una relacion direc…
The Interconnecting Hairpin Extension "Arm": An Essential Allosteric Element of Phytochrome Activity
2023
In red-light sensing phytochromes, isomerization of the bilin chromophore triggers structural and dynamic changes across multiple domains, ultimately leading to control of the output module (OPM) activity. In between, a hairpin structure, "arm", extends from an interconnecting domain to the chromophore region. Here, by removing this protein segment in a bacteriophytochrome from Deinococcus radiodurans (DrBphP), we show that the arm is crucial for signal transduction. Crystallographic, spectroscopic, and biochemical data indicate that this variant maintains the properties of DrBphP in the resting state. Spectroscopic data also reveal that the armless systems maintain the ability to respond t…
Pratiche dell'architettura in Vittorio Ugo (1957-1987)
2014
La ricerca verte sulla figura di Vittorio Ugo (1938-2005), architetto e urbanista palermitano , docente presso la Facoltà di architettura di Palermo dal 1964 al 1987. Della complessa attività di Ugo, che nella seconda fase si svolge principalmente a Milano, la tesi mette a fuoco il periodo 1957-1987, anni che comprendono la formazione universitaria e la sua poco nota attività di architetto e urbanista a Palermo. Vittorio Ugo (Palermo, 1938-2005) is an Italian architect, mostly known in Italy and France as theorist and a critic as well, Professor at University of Palermo from 1964 to 1987. Much less known is his architectural work as author of projects on different scales: architecture, urba…
Platformed Interactions: How Social Media Platforms Relate to Candidate–Constituent Interaction During Finnish 2015 Election Campaigning
2020
Interaction between candidates and constituents via social media is a well-studied domain. The article takes this research further through a synthesis with platform studies, emerging scholarship that applies a critical perspective to the role of digital platforms in society. Examination of candidate–constituent interaction via Twitter and Facebook during the 2015 Finnish parliamentary elections revealed that the types of interaction differ between the two platforms: Facebook was used for formal campaigning and for praising and expressing support, while Twitter was utilized for information and for seeking and sharing opinions. An additional finding is that interaction approaches may be plat…
