Semiconductor nanowires have many properties which makes them interesting for future electronic devices. The fact that they have very small diameters allow them to combine different III-V materials into heterostructures, and makes it possible to grow them on Si substrates which are the basis of nearly all current semiconductor technology. It also allows them to adopt the wurtzite crystal structure

This paper provides an extensive analysis of the demand for alcohol in terms of total quantity and quantity subdivided into frequency and intensity demand. The analysis compares across alcohol types (beer, wine and spirits), alcohol drinking pattern (average drinker vs. binge drinkers) and also how these decisions differ across gender. The analysis is based on a large sample of cross-sectional dat

This study investigates the impact of childhood health on labor market outcomes. We used type 1 diabetes as an instrument of health because its cause is multifactorial and it is triggered by a complex combination of genetic and environmental components; its incidence is low and unforeseeable for the individual; and its onset may be considered an exogenous health shock. Using data from the Swedish

This chapter presents the Development Policy Evaluation Model (DEVPEM), a new simulation model which captures four critical aspects of rural economies in developing countries: 1) the role of the household as both a producer and a consumer of food crops; 2) high transaction costs of participating in markets; 3) market linkages among heterogeneous rural producers and consumers; 4) the imperfect conv

In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length. We are therefore able to investigate friction in th

In this presentation will be given an up-date of the status of epitaxially grown III-V nanowires, from the perspective of growth, processing, physics and applications in the areas of nanoelectronics and nanophotonics

OBJECTIVE: The purpose of this study was to assess the effectiveness of electronic fetal monitoring (EFM) alone and with additional ST analysis (EFM + ST) in laboring women with a singleton term pregnancy that is in cephalic presentation in the prevention of metabolic acidosis by the application of individual patient data metaanalysis. STUDY DESIGN: We conducted an individual patient data metaanal

BACKGROUND: Cancer of unknown primary (CUP) is a fatal cancer for which incidence trends have changed but detailed survival trends remain unexplored. These could point out successful diagnostic and therapeutic approaches. We investigate survival trends in CUP according to histology, locations of metastases and site-specific causes of death. PATIENTS AND METHODS: A total of 20,523 CUP patients with

BackgroundWarfarin is demonstrated to be superior in efficacy over antiplatelet agents for the prevention of stroke, but the relationship between warfarin and mortality is less clear. Our aim was to investigate this relationship in a large cohort of unselected patients with atrial fibrillation and ischaemic stroke. MethodsThis observational study was based on patients who were discharged alive and

The combinatorial nature of many important mathematical problems, including nondeterministic-polynomial-time (NP)-complete problems, places a severe limitation on the problem size that can be solved with conventional, sequentially operating electronic computers. There have been significant efforts in conceiving parallel-computation approaches in the past, for example: DNA computation, quantum comp
