Sequence disorder-induced first order phase transition in confined polyelectrolytes
V. Stepanyan, Artem Badasyan, V. Morozov, Yevgeni S. Mamasakhlisov, Rudolf Podgornik, 2024, original scientific article

Abstract: We consider a statistical mechanical model of a generic flexible polyelectrolyte, comprised of identically charged monomers with long-range electrostatic interactions and short-range interactions quantified by a disorder field along the polymer contour sequence, which is randomly quenched. The free energy and the monomer density profile of the system for no electrolyte screening are calculated in the case of a system composed of two infinite planar bounding surfaces with an intervening oppositely charged polyelectrolyte chain. We show that the effect of the contour sequence disorder, mediated by short-range interactions, leads to an enhanced localization of the polyelectrolyte chain and a first order phase transition at a critical value of the inter-surface spacing. This phase transition results in an abrupt change of the pressure from negative to positive values, effectively eliminating polyelectrolyte mediated bridging attraction.

Magični realizem v filmih Wesa Andersona in Emirja Kusturice
Mateja Nikolić, 2018, undergraduate thesis

Abstract: V diplomskem delu je najprej opredeljen magični realizem, izpostavljeni so njegovi vplivi in pod-žanri. Sledi opis rabe tega žanra v literaturi, televiziji in filmu, nato pa zgodovina neodvisnega filma in pomen filmskega avtorstva ali auteurstva, ki se povezuje z umetniškimi deli režiserja Wesa Andersona. Po kratkem opisu njegove filmske kariere sledi predstavitev Emira Kusturice; njegove avtorske biografije in prakse. Kratka razprava predstavi kako so politični nemiri vplivali na jugoslovanski film in posledično na filmske zgodbe Kusturice. Sledi primerjava dveh filmov obeh avtorjev, kjer so izpostavljene podobnosti v strukturi podajanja zgodbe in njenih elementov na eni ter kadriranja na drugi strani. Po zaključku teoretičnega dela sledi opis procesa nastajanja mojega študentskega filma in kratka kritična analiza tega dela.
Keywords: Film, magični realizem, absurdnost, teatralnost, nadrealizem, Anderson, auteur, Kusturica, Jugoslavija, Balkan, filmografija, stilizacija
