Nanowire heterostructures define high-quality few-electron quantum dots for nanoelectronics, spintronics, and quantum information processing. We use a cooled scanning probe microscope (SPM) to image and control an InAs quantum dot in an InAs/InP nanowire using the tip as a movable gate. Images of dot conductance vs tip position at T=4.2 K show concentric rings as electrons are added, starting with

The number of applications sharing the same embedded device is increasing dramatically. Very efficient mechanisms (resource managers) for assigning the CPU time to all demanding applications are needed. Unfortunately, existing optimization-based resource managers consume too much resource themselves. In this paper, we address the problem of distributed convergence to fair allocation of CPU resourc

Antisymmetric magneto-resistance anomalies generated by a reversal of the magnetization are studied in a number of GaMnAs/InGaAs layers with out-of-plane (easy axis) magnetization. The anomalies occur independent of the magnetic field orientation. This shows, that once a magnetic domain with reversed magnetization is nucleated, simply the presence of the domain wall between the longitudinal contac

During grinding processes, numerous grains interact with the workpiece material producing mechanical and thermal loads on the surface. In the field of thermal simulation of grinding processes, a widely used approach is to substitute numerous cutting edges by a single moving distributed heat source of a specific geometrical shape referring to the theory of Carslaw and Jaeger. This heat source is th

Comparative research related to any aspect of the process of breach in either the pretrial, sentencing or release phases is relatively rare. Comparative studies of decision making in the specific context of breach process are particularly lacking. One reason for the dearth of research in this area is the many challenges presented by comparative research across different jurisdictions. This article

The process of penetration of cobalt atoms through the h-BN nanomesh on Rh(111) is investigated with both spectroscopic and microscopic techniques. It is discovered that oxygen coadsorption can drastically modify the physical properties and behavior of the deposited Co clusters upon postannealing. In the absence of oxygen, Co forms small nanoparticles in the pores (bonding parts) of the h-BN nanom

Cell migration is the first step of the invasive process, which is part of the malignant phenotype, and the uPA receptor (uPAR) plays a central role in cell migration. We studied the role of EGF and estrogen on cell migration and uPAR expression in ovarian cancer cell lines. We also analyzed the diagnostic and prognostic value of cleaved forms of the uPAR in plasma from patients with ovarian tumor

Changes in the Arctic's climate are a result of complex interactions between the cryosphere, atmosphere, ocean, and biosphere. More feedbacks from the cryosphere to climate warming are positive and result in further warming than are negative, resulting in a reduced rate of warming or cooling. Feedbacks operate at different spatial scales; many, such as those operating through albedo and evapotrans

Recurring natural and man-made disasters are resulting in an increasing number of displaced people who need to be provided with urgent accommodation. Due to insufficient legal regulations and effective construction methods, refugees are often located in conditions defined as ‘temporary’, offering low quality of living conditions, degrading social environment and destructive impact on the city land

This thesis describes how software for automated bidding on for example auction sites could function. The thesis is divided into three parts. The elements are composed of: • Collecting bid data from the website that the auction is held on and pass the raw data to the main application for further processing. • A graphical presentation of the auction data is shown divided into individual auctions in

The representation of expressivity of sound and colour in functional information is still a fairly unexplored field. Alternative ways of representing functional information are necessary when providing feedback in technical environments as homes, cars, nuclear power plants, and intensive care. One possible solution could be non-verbal representation of expressivity in functional information using

Background Technological advancements over the last decades have resulted in an increased degree of digitalisation within as well as in between companies around the world. As a result, requirements on companies in general are growing and global competition is steadily increasing. One area for which this is highly relevant, and for which there is still a lot of potential for improvement, is industr

Generellt i samhället, såväl bland allmänheten som i rättssystemet, har det konstaterats att det finns en misstro mot kvinnor som anmäler våldtäktsbrott. En återkommande föreställning är att kvinnor ljuger om vad som inträffat när de anmäler dessa brott. Vidare har den svenska våldtäktsprocessen nyligen kritiserats för att innehålla negativa föreställningar om kvinnor. I denna uppsats undersöker jIn public opinion, as well as in the legal system, there is a general disbelief of those who report rape. This distrust is partially founded on a reoccurring perception that women often lie when reporting crimes of sexual violence. The Swedish legal process has recently been subject to critique for holding negative perceptions about women in rape related court cases. In this study I examine if and

Introduction: While it is recognized that there are costs associated with postoperative patient follow-up, risk assessments of catastrophic health expenditures (CHEs) due to surgery in sub-Saharan Africa rarely include expenses after discharge. We describe patient-level costs for cesarean section (c-section) and follow-up care up to postoperative day (POD) 30 and evaluate the contribution of follo
