DAVID HOMEOMORPHISMS VIA CARLESON BOXES

We construct a family of examples of increasing homeomorphisms of the real line whose local quasi-symmetric distortion blows up almost everywhere, which nevertheless can be realized as the boundary values of David homeomorphisms of the upper half-plane. The construction of such David extensions uses Carleson boxes.

Thermodynamic stability of nanosized multicomponent bubbles/droplets: The square gradient theory and the capillary approach

Formation of nanosized droplets/bubbles from a metastable bulk phase is connected to many unresolved scientific questions. We analyze the properties and stability of multicomponent droplets and bubbles in the canonical ensemble, and compare with single-component systems. The bubbles/droplets are described on the mesoscopic level by square gradient theory. Furthermore, we compare the results to a capillary model which gives a macroscopic description. Remarkably, the solutions of the square gradient model, representing bubbles and droplets, are accurately reproduced by the capillary model except in the vicinity of the spinodals. The solutions of the square gradient model form closed loops, which shows the inherent symmetry and connected nature of bubbles and droplets. A thermodynamic stability analysis is carried out, where the second variation of the square gradient description is compared to the eigenvalues of the Hessian matrix in the capillary description. The analysis shows that it is impossible to stabilize arbitrarily small bubbles or droplets in closed systems and gives insight into metastable regions close to the minimum bubble/droplet radii. Despite the large difference in complexity, the square gradient and the capillary model predict the same finite threshold sizes and very similar stability limits for bubbles and droplets, both for single-component and two-component systems.

Interpersonal understanding and theory of mind

En populär idé inom dagens filosofiska och psykologiska forskning om interpersonlig förståelse, är idén att vi använder en kognitiv funktion (eller metod) för att förstå andra människor, en så kallad ”theory of mind” funktion. Denna idé förekommer inom ett brett vetenskapligt fält så som inom evolutionspsykologi, inom teorier om barns utveckling, inom teorier om autism, samt inom emotionsfilosofi och moralfilosofi. Avsikten i denna studie är att se närmare på vissa inflytelserika filosofiska och psykologiska teorier om interpersonlig förståelse, teorier som också har en stark koppling till empirisk forskning. I arbetet hävdar Gustafsson att teorierna ifråga avspeglar vissa klassiska, filosofiskt problematiska, antaganden. Dessa antaganden präglar teorierna ifråga samt påverkar hur de empiriska undersökningarna byggs upp och hur resultat tolkas.

Diseño de un banco comunal para familias reubicadas de la zona de Santa Inés-El Cartucho

La pobreza en el contexto urbano colombiano, ha adquirido un carácter estructural, como resultado de la superposición de varios factores. En primer lugar, las migraciones de las zonas rurales a la ciudad, derivadas de la violencia política, han ocasionado no sólo un crecimiento demográfico y urbanístico desordenado, sino que dada la baja capacidad de la economía citadina para absorber en el mercado de trabajo la creciente mano de obra inmigrante, -que por demás en su mayoría tiene bajos niveles educativos- para esta población , solo queda como alternativa de supervivencia, el ejercicio de actividades informales, ilegales, o formales de bajo perfil con precaria remuneración, lo cual no sólo impide que logren mejorar su calidad de vida mediante la satisfacción de sus necesidades básicas, sino que además, determina la reproducción de los círculos de pobreza e inequidad, creando una singular patología social.

Impact of cyclones on sea ice in the Fram Strait: numerical simulations and observations

The sea ice export from the Arctic is of global importance due to its fresh water which influences the oceanic stratification and, thus, the global thermohaline circulation. This study deals with the effect of cyclones on sea ice and sea ice transport in particular on the basis of observations from two field experiments FRAMZY 1999 and FRAMZY 2002 in April 1999 and March 2002 as well as on the basis of simulations with a numerical sea ice model. The simulations realised by a dynamic-thermodynamic sea ice model are forced with 6-hourly atmospheric ECMWF- analyses (European Centre for Medium-Range Weather Forecasts) and 6-hourly oceanic data of a MPI-OM-simulation (Max-Planck-Institute Ocean Model). Comparing the observed and simulated variability of the sea ice drift and of the position of the ice edge shows that the chosen configuration of the model is appropriate for the performed studies. The seven observed cyclones change the position of the ice edge up to 100 km and cause an extensive decrease of sea ice coverage by 2 % up to more than 10 %. The decrease is only simulated by the model if the ocean current is strongly divergent in the centre of the cyclone. The impact is remarkable of the ocean current on divergence and shear deformation of the ice drift. As shown by sensitivity studies the ocean current at a depth of 6 m – the sea ice model is forced with – is mainly responsible for the ascertained differences between simulation and observation. The simulated sea ice transport shows a strong variability on a time scale from hours to days. Local minima occur in the time series of the ice transport during periods with Fram Strait cyclones. These minima are not caused by the local effect of the cyclone’s wind field, but mainly by the large-scale pattern of surface pressure. A displacement of the areas of strongest cyclone activity in the Nordic Seas would considerably influence the ice transport.
