Embedded systems often operate in so variable con- ditions that design can only be carried out for some worst-case scenario. This leads to over-provisioned resources, and undue power consumption. Feedback control is an effective (and not yet fully explored) way to tailor resource usage online, thereby making the system behave and consume as if it was optimized for each specific utilization case. A
To test the theory that sexual offenders who abuse very young children (0-5 years) have more severe mental health and psychosocial problems than those who victimize older children, authors compared psychiatric diagnoses, social circumstances, and crime-related data in all sexual offenders against minors referred to forensic psychiatric investigation in Sweden during a 5-year period. Thirty-one men
In this work we investigate the variation of the crystal structure of gold-seeded III-V nanowires with growth parameters, in order to gain a cohesive understanding of these effects. We investigate six III-V materials: GaAs, InAs, GaP, InP, GaSb and InSb, over a variation of growth conditions. All six of these materials exhibit a cubic zinc blende structure in bulk, but twin planes and stacking fau
Background: Alzheimer's disease (AD) is associated with deposition of amyloid beta (A beta) in the brain, which is reflected by low concentration of the A beta 1-42 peptide in the cerebrospinal fluid (CSF). There are at least 15 additional A beta peptides in human CSF and their relative abundance pattern is thought to reflect the production and degradation of A beta. Here, we test the hypothesis t
Popular Abstract in Swedish Under den senaste tiden har problematiken med klimatförändringarna debatterats livligt. För att kunna förutspå den framtida omfattningen av klimatförändringarna och vilka konsekvenser dessa kommer att ha är det ytterst relevant att känna till utbytet av växthusgaser mellan atmosfär och jordens alla ekosystem. Arktiska ekosystem är ytterst känsliga för den globala uppvärArctic ecosystems play a key role in the terrestrial carbon (C) cycle, but spa-tially explicit data on the C exchange is scarce in these remote areas. The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. It is therefore important to quantify and understand the processes affecting the C dynamics in these regions. In this thesis, the land-atmosp
Applications of IDA in, for example, immobilized metal ion affinity chromatography for purification of His-tagged proteins are well recognized. The use of IDA as an efficient chelating adsorbent for environmental separations, that is, for the capture of heavy metals, is not studied. Adsorbents based on supermacroporous gels (cryogels) bearing metal chelating functionalities (IDA residues and ligan
Following the fragmentation of a 550 MeV u(-1)primary beam of Ni-58, time-and energy-correlated gamma decays from isomeric states in neutron-deficient nuclei in the 1f(7/2) shell have been identified using the GSI fragment separator in combination with the RISING Ge-detector array. The results on isomers in the mirror pairs Ti-43(22)21-Sc-43(21)22 (I-pi = 3/2(+) and 19/2(-)), Cr-45(24)21-Sc-45(21)
The amount of installed wind power varies significantly across municipalities although the financial support for wind power production and the technology available is identical in all Swedish municipalities. This study analyses how local differences between municipalities, such as local wind prerequisites and socioeconomic conditions, might explain the establishment of wind power. The analysis is
As a field of historical research, the history of the emotions has been expanding rapidly in the last decade. Although it is a field with an obvious identity, it lacks a clear consensus on methodology; neither have various schools of thought been recognized. However, in this brief introduction to the field I argue that two different approaches can be distinguished in research on the history of the
This study relates to the topic of anchorage of shear walls. At times, eccentric forces between the sheathing and the anchoring devices may be introduced in the sill plate. In severe cases, such forces may cause the sill plate to split and to fail in a brittle manner. In this study, fracture mechanics are applied to develop a simple closed-form hand-calculation expression for estimation of the
To assess the prognostic importance of high-sensitive C reactive protein (hsCRP) in patients with mild to moderate aortic valve stenosis during placebo or simvastatin/ezetimibe treatment in Simvastatin and Ezetimibe in Aortic Stenosis (SEAS).
In the wake of preventive thinking, attention has turned towards a life cycle perspective of products. Businesses can no longer ignore the environmental impacts of the products outside the borders of their own facilities. Consequently companies are now extending their environmental considerations beyond their internal production to include the environmental performance of their suppliers and suppl
Levels of circulating glucose are tightly regulated. To identify new loci influencing glycemic traits, we performed meta-analyses of 21 genome-wide association studies informative for fasting glucose, fasting insulin and indices of beta-cell function (HOMA-B) and insulin resistance (HOMA-IR) in up to 46,186 nondiabetic participants. Follow-up of 25 loci in up to 76,558 additional subjects identifi
Predicting the risk of future events is an essential part of health economic simulation models. In pursuit of this goal, the current study aims to predict the risk of developing first and second acute myocardial infarction, heart failure, non-acute ischaemic heart disease, and stroke after diagnosis in patients with type 2 diabetes, using data from the Swedish National Diabetes Register.

CCR5-using (R5) human immunodeficiency virus type 1 (HIV-1) strains cause CD4+ T-cell loss in most infected individuals, but mechanisms underlying cytopathicity of R5 viruses are poorly understood. We investigated mechanisms contributing to R5 envelope glycoprotein (Env)-mediated cellular apoptosis by constructing a panel of retroviral vectors engineered to co-express GFP and R5 Envs derived from
In recent times, the imminent lack of public IPv4 addresses has attracted the attention of both research community and industry. The cellular industry has decided to combat this problem by using IPv6 for all new terminals. However, the success of 3G network deployment will depend on the services offered to end users. Currently, almost all services reside in the public IPv4 address space, making th
Type-2 diabetes (T2D) is a complex disease characterized by insulin resistance in target tissues and impaired insulin release from pancreatic beta cells. As central tissue of glucose homeostasis, the pancreatic islet continues to be an important focus of research to understand the pathophysiology of the disease. The increased access to human pancreatic islets has resulted in improved knowledge of
