Intramolecular phase separation of copolymer "bottle brushes": No sharp phase transition but a tunable length scale
2006
A lattice model for a symmetrical copolymer "bottle brush" molecule, where two types (A,B) of flexible side chains are grafted with one chain end to a rigid backbone, is studied by a variant of the pruned-enriched Rosenbluth method (PERM), allowing for simultaneous growth of all side chains in the Monte Carlo sampling. Choosing repulsive binary interactions between unlike monomers and varying the solvent quality, it is found that phase separation into an $A$-rich part of the cylindrical molecule and a $B$-rich part can occur only locally. Long range order (in the direction of the backbone) does not occur, and hence the transition from the randomly mixed state of the bottle brush to the phas…
Spatial correlations of mobility and immobility in a glass-forming Lennard-Jones liquid
1998
Using extensive molecular dynamics simulations of an equilibrium, glass-forming Lennard-Jones mixture, we characterize in detail the local atomic motions. We show that spatial correlations exist among particles undergoing extremely large (``mobile'') or extremely small (``immobile'') displacements over a suitably chosen time interval. The immobile particles form the cores of relatively compact clusters, while the mobile particles move cooperatively and form quasi-one-dimensional, stringlike clusters. The strength and length scale of the correlations between mobile particles are found to grow strongly with decreasing temperature, and the mean cluster size appears to diverge near the mode-cou…
How to define variation of physical properties normal to an undulating one-dimensional object.
2009
One-dimensional flexible objects are abundant in physics, from polymers to vortex lines to defect lines and many more. These objects structure their environment and it is natural to assume that the influence these objects exert on their environment depends on the distance from the line-object. But how should this be defined? We argue here that there is an intrinsic length scale along the undulating line that is a measure of its "stiffness" (i.e., orientational persistence), which yields a natural way of defining the variation of physical properties normal to the undulating line. We exemplify how this normal variation can be determined from a computer simulation for the case of a so-called b…
Residual Stresses in Glasses
2013
The history dependence of the glasses formed from flow-melted steady states by a sudden cessation of the shear rate $\dot\gamma$ is studied in colloidal suspensions, by molecular dynamics simulations, and mode-coupling theory. In an ideal glass, stresses relax only partially, leaving behind a finite persistent residual stress. For intermediate times, relaxation curves scale as a function of $\dot\gamma t$, even though no flow is present. The macroscopic stress evolution is connected to a length scale of residual liquefaction displayed by microscopic mean-squared displacements. The theory describes this history dependence of glasses sharing the same thermodynamic state variables, but differi…

‘Philonikia’ e ‘timoria’ nel ‘logos’ di Ermocrate a Gela e nell’‘Olimpico’ di Lisia
2016
The aim of the paper is to underline that some themes are both in the logos of Hermocrates of Syracuse in Gela and in the Olimpic Oration of Lysias. Purposely, two of these are the theme of philonikia , which Thucydides defined «insane», and the theme of timoria , when the revenge is legitimate and advantageous at same time. The use of such slogans by the Attic orator (even if his father was from Syracuse), testifies the desire to evoke the feeling pansikeliote awaked during the Peace of Gela, in order to spread these themes and values in Mainland Greece too.
Why Translation Is Difficult
2017
The paper develops a definition of translation literality that is based on the syntactic and semantic similarity of the source and the target texts. We provide theoretical and empirical evidence that absolute literal translations are easy to produce. Based on a multilingual corpus of alternative translations we investigate the effects of cross-lingual syntactic and semantic distance on translation production times and find that non-literality makes from-scratch translation and post-editing difficult. We show that statistical machine translation systems encounter even more difficulties with non-literality.
Amplified John? Kristologiske tekster i Johannesevangeliet og Bibelselskapets NT05-oversettelse
2011
Author's version of an article published in the journal: Tidsskrift for teologi og kirke. Also available from the publisher at: http://www.idunn.no/ts/ttk/2011/02/art03 The article argues that the latest translation of the New Testament (NT05) by the Norwegian Bible Society has a tendency to amplify several Christological texts in the Gospel of John. It consists of two parts: Part 1 discusses the translation of John 1:1–5, 1:14, 1:15 and 1:18, and offers a new general interpretation of the prologue. Part 2 treats the translation of ekserkjomai in Joh 8:42, 13:3, 16:27–30, and 17:8.
Ocnos : revista de estudios sobre lectura
2014
Este artículo documenta los espacios virtuales que congregan diariamente a cientos de adolescentes y jóvenes entre 13 y 29 años para hablar de libros, lectura y de autores. En estos espacios intercambian lecturas, reseñan sus relatos preferidos en sus blogs, debaten sobre si el narrador es adecuado para la narración o se quejan de cómo se trata la lectura en la escuela. La investigación se ha realizado a partir del estudio de dos casos: los foros de Laura Gallego y la campaña de promoción de venta del libro Delirium, de la Editorial SM, a través de los blogs administrados por los adolescentes y de las redes sociales Twitter y Facebook. Se han analizado 1.466 documentos de 452 sujetos para c…
