Two-particle azimuthal correlation functions are presented for charged hadrons produced in Au+Au collisions at the Relativistic Heavy Ion Collider (sqrt[sNN]=130 GeV). The measurements permit determination of elliptic flow without event-by-event estimation of the reaction plane. The extracted elliptic flow values (v2) show significant sensitivity to both the collision centrality and the transverse
This study investigated if clothing material with reflective properties has an effect on heat gain in pilot, specifically, under solar radiation. Two materials, conventional pilot suit material (Old) and material coated with coldblack® (New, Schoeller Technologies AG, Switzerland) were tested over variety of underwear layers and in a box simulating cockpit. A hot plate was used to measure textile
Lattice decoders for MIMO systems, including the sphere decoder (SD) and the Schnorr-Euchner (SE) decoder, have been shown to approach the performance of Maximum-likelihood decoder with low complexity. There are three kinds of lattice decoder, sequential SD, K-best SD and sequential SE, which are popular in the literature. As a modification to the K-best SD, a lower complexity K-best SE is propose
BackgroundRespiratory diseases are the most common cause for seeing a doctor in Nicaragua, and the second most common cause of death in children. An air monitoring program in the capital city, Managua, has shown high levels of air pollution, especially small particles. Important sources for this pollution are road traffic, smoke from cooking with wood, from burning of sugar cane fields before harv

Popular Abstract in Swedish Svensk sammanfattning Inflammation är kroppens svar på yttre störning. Det inflammatoriska svaret är nödvändigt för att bekämpa infektioner, t.ex. med bakterier. Å andra sidan orskar det inflammatoriska svaret mycket skada när det aktiveras utan närvaro av infektioner, tex vid astma, reumatism, blodförgiftning och inflammatorisk tarmsjukdom. Akut inflammation karaktäriMigration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. Tumor necrosis factor-alpha (TNF-alpha) is pleiotrophic cytokine, which plays an important role in t
“Die Unruhe und Ungewissheit sind unser Theil”, writes Goethe in a letter to the German novelist Sophie von la Roche in 1774. But is it the incalculable and indeterminate that cause disquiet, or is it our bustling pursuit of knowledge that makes us uncertain? Contemporary psychologists have taught us a great deal about the way we perceive risks and about the way affects and emotions influence our
Miniaturized (<1 L) biospecific affinity two-phase partitioning in an acoustically levitated drop is described. Miniaturization commonly gives unfavorable surface/volume ratios, but in the levitation approach adsorption problems are minimized since the only surrounding wall is the liquid/air interface of the drop. Biotinylated liposomes were partitioned in aqueous poly(ethylene glycol)/dextran two
In this paper, we consider a fully decentralized control problem with two dynamically decoupled agents. The objective is to design a state-feedback controller for each agent such that a global quadratic cost is minimized. No communication, explicit or implicit, is permitted between the agents. However, the performance of the agents is coupled via the cost function as well as the process noise. We
Popular Abstract in Swedish I min forskning undersöker jag hur lagar och regler om asyl översätts till praktik i handläggningen av asylärenden i Sverige. Mina utgångspunkter är samhällets organisation av asylprövningen och strukturerna i denna organisation. I avhandlingen finns en redogörelse för ett enskilt fall. I detta fall finns en mängd av de olika problem som uppstår i asylärenden representeThe purpose of my research is to examine the translation of logos into praxis in the handling of asylum-cases in Sweden. My point of departure has been the manner in which society has organised the handling of asylum-cases and the structure of this organisation. My thesis contains an account of an individual case which is representative of a multitude of problems in the asylum case handling. Casew
