The shot noise behavior of sequential tunneling through two vertically coupled quantum dots is studied by means of a master equation approach. In particular, we propose a mechanism to observe super-Poissonian shot noise in such a system. The crucial ingredient is the Coulomb interaction between electrons in individual quantum dots.
Abstract in Danish LÆRING I OG AF KLINISK PRAKSIS sigter mod at forberede og styrke både de professionsbachelorstuderende indenfor sundhedsområdet, primært sygeplejestuderende, i deres møde med de kliniske uddannelsessteder og de kliniske uddannelsessteders møder med de studerende. Bogen belyser en række udfordringer, som disse møder giver, og hvilke læringsmuligheder der opstår, når den studeren
Popular Abstract in Swedish Avhandlingens syfte är att söka kunskap om vilka faktorer som bidrar till uppfostringsanstaltens framgång som social institution och dess ständiga misslyckande som behandlingsorganisation. Jag försöker förstå varför organisationer som §12-hem och särskilda ungdomshem finns och vilken betydelse de har i vårt samhälle. Svaret på den frågan söker jag på tre sätt: genom attThe aim of the present study is to find the factors and conditions that generate the success of the reformatory as a social institution and, at the same time, its well-known failure as a treatment organization. I try to understand why organizations like the reformatory exist and what meaning they have in our society. I seek answers by exploring the birth of the reformatory in a historical perspect
En studie av tidsvinstens värde. Hur värderas den tidsvinst som tunneln genom Hallandsåsen förväntas medföra ur olika perspektiv?
Variability in fire regime at the continental scale has primarily been attributed to climate change, often overshadowing the widely potential impact of human activities. However, human ignition modifies the rhythm of fire episodes occurrence (fire frequency), whereas land use alters vegetation composition and fuel load, and thus the amount of biomass burned. It is unclear, however, whether and how
Popular Abstract in Swedish Mellan 0.3 och 2.1 % av alla barn föds med portvins fläckar (PWS). Till skillnad mot vissa andra kärlmissbildningar försvinner inte PWS utan tvärtom blir många mer blåröda och tjockare med åren. Majoriteten av patienterna upplever sig vara negativt psykosocialt påverkade av sitt PWS i jämförelse med jämnåriga. Dessa negativa upplevelser minskar efter behandlingarna.(Se This thesis covers 12 years of experience in treating patients with congenital capillary malformations, so called port wine stains (PWS). The wide variation in treatment response to laser therapy has developed a profound need for the development of objective devises to measure treatment outcome, so that the maximum effectiveness of therapy can be achieved without unnecessary treatments. The purpos
First results from a study into the abundance trends of oxygen in the Galactic thin and thick disks are presented. Oxygen abundances for 63nearby F and G dwarf stars, based on very high resolution spectra (R∼215 000) and high signal-to-noise (S/N>400) of the faint forbidden oxygen line at 6300Å, have been determined. Our findings can be summarized as follows: 1) at [Fe/H]<0 the oxygen trends in th
Popular Abstract in Swedish Fotosyntesen är den mest grundläggande förutsättningen för människans överlevnad. Genom att absorbera solenergi och omvandla den till kemiskt bunden energi i form av energirika organiska molekyler, står fotosyntesen för nästan all tillförsel av energi till vårt ekosystem. Energin utnyttjas som mat, till oss och till djuren vi beror av, och som bränsle, fossilt eller färIn this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). It is a Mn-derived signal displaying clear hyperfine structure, centered at g=2, and is significantly broader than the well-known multiline signal from the S2 state, indicating the presence of MnII in

Popular Abstract in Swedish Läkemedel blir allt viktigare behandlings-instrument och kunskapen ökar om läke-medels verkningsmekanismer. Även om denna kunskap kombineras med resultat från kliniska läkemedelsprövningar är detta dock inte tillräckligt för att värdera kliniska fördelar och risker med en rutinmässig läkemedels-behandling, särskilt inte om behandlingen är långvarig. För detta ändamål beThe efficacy and safety of antihyperglycaemic drugs have been evaluated in one American and one British randomized clinical trial, which have given contradictory results. The positive results of the latter may be more convincing as it included a greater number of patients and as its duration was longer. However, its conclusions may not be applicable to type 2 diabetes patients in general, as the s
The objective of the work presented in this paper is to design and develop a framework for simulation of requirements engineering processes. The framework is intended to be a support when simulation models are built by guiding the modeler in which components to use in this type of models and to speed up the process of developing simulation models. The framework was developed through an iterative p
We raise the question whether there is a rigorous argument favoring one jury system over another. We provide a Bayesian model of deliberating juries that allows for computer simulation for the purpose of studying the effect of jury size and required majority on the quality of jury decision making. We introduce the idea of jury value (J-value), a kind of epistemic value which takes into account the
Collection attributes, as defined by Boyland, can be used as a mechanism for concisely specifying cross-reference-like properties such as callee sets, subclass sets, and sets of variable uses. We have implemented collection attributes in our declarative meta programming system JastAdd, and used them for a variety of applications including devirtualization analysis, metrics, and flow analysis. We p
