1. 16. Characterization of supported lipid membranes towards the development of nano-sized drug carriers for hyperthermia applications

   Författare :Yujia Jing; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; size dependence; Supported lipid membrane; lipid phase transition; flip-flop; asymmetry;

   Sammanfattning : So called thermosensitive liposomal drug carriers for temperature-controlled drug release under hyperthermal conditions have recently attracted great attention and advanced lipid membrane - nanoparticle assemblies are emerging at an increasing rate to meet the demands for multifunctional drug carriers in medicine. The rational design of these drug delivery systems will require understanding of lipid membrane physicochemical properties under conditions relevant to the medical treatment. LÄS MER

   Sammanfattning : Abstract Sophisticated liposomal systems are emerging at an increasing rate to meet the demands for multifunctional drug carriers in chemotherapies in combined with hyperthermia. For example, liposomal drug carriers for temperature-controlled drug release under hyperthermic conditions have recently been tested in clinical trials. LÄS MER

4. 18. Demand responsive resource management for cellular networks : link asymmetry, pricing and multihopping

   Författare :Magnus Lindström; Jens Zander; Narayan Mandayam; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : Economic affordability of services and infrastructures has rapidly become one of the key issues in the evaluation and design of wireless access systems. The provisioning of high data rates, at an ``affordable'' price, constitutes a serious challenge to the structure and management of current and future wireless networks. LÄS MER

5. 19. On Risk Prediction

   Författare :Carl Lönnbark; Kurt Brännäs; Stefan Mittnik; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Finance; Time series; GARCH; Estimation error; Asymmetry; Supply and demand; Econometrics; Ekonometri; ekonometri; Econometrics;

   Sammanfattning : This thesis comprises four papers concerning risk prediction. Paper [I] suggests a nonlinear and multivariate time series model framework that enables the study of simultaneity in returns and in volatilities, as well as asymmetric effects arising from shocks. LÄS MER

7. 20. The Human Right to Leave: But Whereto?

   Författare :Guilherme Marques Pedro; Patricia Mindus; Gregor Noll; Paulina Ochoa Espejo; Uppsala universitet; []

   Sammanfattning : While all persons — with a few exceptions — are allowed to leave any country regardless of nationality, not all persons are allowed to enter any country of their choosing; and only citizens enjoy, in principle, the right to enter their country of nationality, which most often, and by necessity, is a restricted number of countries, since some of them prohibit multiple nationality. One claim that is frequently made in contemporary migration-related literature, and that much migration-related philosophical debate presupposes in one way or another, yet remains unexplored, is the claim that the right to leave a state – enshrined in the Universal Declaration of Human Rights of 1948 – does not entail a right to enter another state.
