Closely spaced local gate electrodes are used to electrically define a double quantum dot along an InAs nanowire crystal. By applying a periodic pulse sequence to two plunger gate electrodes controlling the double quantum dot charge configuration, the device is operated as a single electron pump. The authors find that within measurement accuracy, the pumping current equals one electron per cycle f

Popular Abstract in Swedish Infektiös hepatit eller gulsot kan orsakas av flera olika sorters virus. De har alla det gemensamt att de orsakar en inflammation av levern. Namnet gulsot kommer av att när leverns funktion nedsätts så ansamlas ett färgämne i kroppen och ger ögonvitorna och huden en synlig gulgrön färg. Efter hand som de olika gulsotsvirusen har upptäckts har de namngivits efter alfabetHepatitis B virus is a non-cytopathic virus with a small, circular, partially double-stranded DNA of 3.2 kb. It causes acute and chronic inflammatory liver disease and hepatocellular carcinoma (HCC). Retesting of stored sera from an outbreak of acute hepatitis in 1969-72 allowed identification of 126 cases of acute hepatitis B. No chronic carriers expressing hepatitis B surface antigen (HBsAg) cou

The history of information systems research is steeped in a quest for appropriate methodologies, rigueur within complexity and an evolution of approaches. Currently this evolutionary trend may be seen to culminate in a siding of IS research within critical frameworks. In this paper we will draw on a relationship between IS research and system analysis to use similarities and differences in an atte

Vehicle-to-vehicle (VTV) communications are of interest for applications within traffic safety and congestion avoidance, but the development of suitable communications systems requires accurate models for the VTV propagation channel. This paper presents a new wideband MIMO (multipleinput- multiple-output) channel model for VTV channels based on extensive MIMO channel measurements performed at 5.2

Thermo-mechanical fatigue crack propagation in Inconel 718 has been studied with different methods. In-situ observations with a scanning electron microscope (SEM) were performed, the crack propagation process was followed cycle by cycle and the influences from load, temperature, and microstructure on the crack growth were analyzed. To measure the displacements an image analysis technique was devel

Most embedded control systems have constrained computationalresources. This makes codesign of the control algorithms and thereal-time scheduling an interesting issue. There is also a strongtrend in the real-time community of moving away from the hardreal-time model. Hence, embedded controllers must be designed sothat they are aware of the resource constraints and timinguncertainty of the implement

Popular Abstract in Swedish Forskningsprojektet som rapporteras i denna avhandling har två övergripande mål. Det första målet är att utveckla testinstrument avsett för avancerade svenska inlärare av engelska, som genererar reliabla och valida testpoäng kopplat till receptiv kunskap avseende engelska kollokationer som en specifik förmåga. Med kollokationer avses konventionaliserade och frekvent förThe research reported in this thesis has two main aims. The first aim is to develop tests capable of yielding reliable and valid scores of receptive knowledge of English collocations as a single construct, for use with advanced L2 learners of English. Collocations are seen as conventionalized, recurring combinations of words, and the targeted types are adjective + NP and verb + NP. The second aim
