Mapping of polycrystalline films of biological fluids utilizing the Jones-matrix formalism
Utilizing a polarized light approach, we reconstruct the spatial distribution of birefringence and optical activity in polycrystalline films of biological fluids. The Jones-matrix formalism is used for an accessible quantitative description of these types of optical anisotropy. We demonstrate that differentiation of polycrystalline films of biological fluids can be performed based on a statistical analysis of the distribution of rotation angles and phase shifts associated with the optical activity and birefringence, respectively. Finally, practical operational characteristics, such as sensitivity, specificity and accuracy of the Jones-matrix reconstruction of optical anisotropy, were identified with special emphasis on biomedical application, specifically for differentiation of bile films taken from healthy donors and from patients with cholelithiasis

From Victim Diaspora to Transborder Citizenship? : Diaspora formation and transnational relations among Kurds in France and Sweden
Denna avhandling är en komparativ undersökning av pågående förändringsprocesser bland kurder i Marseillesregionen i Frankrike och Stockholmsregionen i Sverige. I fokus står skiftet från en endimensionell och offerrelaterad kurdisk diasporisk identitet mot en mer sammansatt och aktiv. Studien går bortom entydiga erfarenheter av smärta, trauma och offerkänsla i syfte att lyfta fram en rad andra diasporiska situationer och företeelser såsom institutionella och transnationella formationer, assabiyya nätverk, ”on air” och ”online” verksamheter, kulturella och litterära aktiviteter osv., som samtliga är centrala element när det gäller att upprätthålla ett gränsöverskridande medborgarskap bland diasporiska kurder i de bägge länderna. Studien vidhåller dessutom att kurder i både Sverige och Frankrike på olika sätt är utsatta för diskriminering och socialt utanförskap. Avhandlingen visar hur kurder i Frankrike och Sverige utvecklar olika diasporiska diskurser och handlingsmönster. Beroende på en relativt likartad social bakgrund och på den exkluderande politiska miljö som finns i Frankrike så upprätthåller kurderna i Marseillesområdet en påtagligt offerrelaterad diasporisk diskurs. Samtidigt är framväxten av ett gränsöverskridande medborgarskap här starkt begränsad. Eftersom kurderna i Sverige är dels jämförelsevis socialt och politiskt diversifierade och dels vistas i en mer gynnsam politisk miljö upprätthåller de inte bara en mer flexibel diasporisk diskurs än kurder i Marseillesområdet. De har också utvecklat ett mer långtgående gränsöverskridande medborgarskap.This study is a comparative exploration of an ongoing process of change from a mono-dimensional, victim-related Kurdish diasporic identity to a more modulated, dynamic and active form of it among Kurds in the Marseille region in France and the Stockholm region in Sweden. The study goes beyond the experience of pain and trauma and the sense of victimhood in order to depict a multitude of other diasporic situations and trajectories such as institutional and transnational arrangements, assabiyya networks, “on air” and cyberspace “online” involvements, cultural and literary activities, and so forth, which are necessary elements for the development of the practice of transborder citizenship among diasporan Kurds in the two countries. The study argues that the Kurds in France and Sweden have conceived different diasporic discourses and at the same time have chosen different modes of action. Due to their uniform social background and the exclusionary French political environment, the Kurds in the region of Marseille maintain a tangible victim diaspora discourse and limited practice of transborder citizenship. As the Kurds in Sweden are socially and politically diversified, and as they live in the more favorable Swedish political environment, they maintain not only a flexible diaspora discourse but also a more highly developed practice of transborder citizenship than the Kurds in the Marseille region
Mapping of polycrystalline films of biological fluids utilizing the Jones-matrix formalism
Abstract
Utilizing a polarized light approach, we reconstruct the spatial distribution of birefringence and optical activity in polycrystalline films of biological fluids. The Jones-matrix formalism is used for an accessible quantitative description of these types of optical anisotropy. We demonstrate that differentiation of polycrystalline films of biological fluids can be performed based on a statistical analysis of the distribution of rotation angles and phase shifts associated with the optical activity and birefringence, respectively. Finally, practical operational characteristics, such as sensitivity, specificity and accuracy of the Jones-matrix reconstruction of optical anisotropy, were identified with special emphasis on biomedical application, specifically for differentiation of bile films taken from healthy donors and from patients with cholelithiasis
