Employing fault tolerance often introduces a time overhead, which may cause a deadline violation in real-time systems (RTS). Therefore, for RTS it is important to optimize the fault tolerance techniques such that the probability to meet the deadlines, i.e. the Level of Confidence (LoC), is maximized. Previous studies have focused on evaluating the LoC for equidistant checkpointing. However, no stu

Performance of cutting tool in hard turning is significantly influenced by its microgeometry, such as edge radius. This study presents an experimental exploration to understand the effect of cutting edge radius on machining performance in terms of surface roughness and tool wear. The cutting tools (CBN) with three groups of nominal edge radius, 20, 30, and 40 μm, were used in the study. The cuttin

Background: Assessing radiographers' clinical competence is of major importance in all medical imaging departments, and is a fundamental prerequisite for guaranteeing professional standards in both nursing care and radiography. Despite the fact that self-assessment has been reported to be the most common form of competence evaluation only several studies defining the radiographers' self-assessment

To understand host–parasite interactions, it is necessary to quantify variation and covariation in defence traits. We quantified parasite resistance and fitness tolerance of a polymorphic damselfly (Ischnura elegans), an insectwith three discrete female colour morphs but with monomorphic males. We quantified sex and morph differences in parasite resistance (prevalence and intensity of water mite i

Precision diabetes medicine, the optimisation of therapy using patient-level biomarker data, has stimulated enormous interest throughout society as it provides hope of more effective, less costly and safer ways of preventing, treating, and perhaps even curing the disease. While precision diabetes medicine is often framed in the context of pharmacotherapy, using biomarkers to personalise lifestyle

Arne Thell och hans tyska kollega Ulf Schiefelbein har undersommaren 2016 undersökt gamla förekomster av lunglav iSkåne med tyvärr tämligen nedslående resultat. Här rapporterarde vad de kommit fram till.

The Univalent Foundations project constitutes what is arguably the most serious challenge to set-theoretic foundations of mathematics since intuitionism. Like intuitionism, it differs both in its philosophical motivations and its mathematical-logical apparatus. In this paper we will focus on one such difference: Univalent Foundations’ reliance on an intensional rather than extensional logic, throu

Sveriges Lichenologiska Förening (SLF) gör årligen två exkursioner, där den höstliga ofta går till den norra halvan av landet. Den 12-13 september 2015 exkurerade vi längs den jämtländska delen av Indals-älven.

I april 2016 gick föreningens vårexkursion till trakterna runt Växjö, med några helt skilda miljöer som mål. Här redogör Emil Persson och Ulf Arup för exkursionen som innebar deltagarrekord med god marginal. Första dagen deltog hela 56 personer.

Increasing evidence supports the benefit of identifying BRCA1 and BRCA2 germline mutations in early breast cancer. Selection of patients for genetic testing is based on defined criteria taking individual and family history related factors into account. It is important to make a distinction between efficacy and effectiveness of BRCA testing criteria. Efficacy can be defined as the performance under

Background: Staphylococcus aureus (SA) is an important human pathogen that causes both superficial and invasive infections. Penicillin is now rarely used in the treatment of SA infections due to widespread resistance and a concern about the accuracy of existing methods for penicillin susceptibility testing. The aims of the present study were to determine the frequency of penicillin-susceptible SA

The catastrophic disruption of the L chondrite parent body in the asteroid belt c. 470 Ma initiated a prolonged meteorite bombardment of Earth that started in the Ordovician and continues today. Abundant L chondrite meteorites in Middle Ordovician strata have been interpreted to be the consequence of the asteroid breakup event. Here we report a zircon U-Pb date of 467.50±0.28 Ma from a distinct be

The power of visual imagery is well known, enshrined in such familiar sayings as "seeing is believing" and "a picture is worth a thousand words." Iconic photos stir our emotions and transform our perspectives about life and the world in which we live. On September 2, 2015, photographs of a young Syrian child, Aylan Kurdi, lying face-down on a Turkish beach, filled the front pages of newspapers wor

Should an inflation-targeting central bank have an explicit tolerance band around its inflation target? This paper provides an answer derived from the Swedish experience. The Riksbank is exceptional in the sense that it first adopted and later abolished an explicit band and is currently considering bringing it back. We conclude that the band should be explicit for several reasons. Most important, Should an inflation-targeting central bank have an explicit tolerance band around its inflation target?

Background: Chronic non-healing wounds present a substantial economic burden to healthcare system; significant reductions in quality of life for those affected, and precede often serious events such as limp amputations or even premature deaths. This burden is also likely to increase with a larger proportion of elderly and increasing prevalence of life-style diseases such as obesity and diabetes. R

Using a standard model where the individual consumption path is computed solving an optimal control problem, we investigate central claims of Piketty (2014) Rather than r>g (confirmed in the data) r-s>g - with s being the rate of time preference - matters. If this condition holds and the elasticity of substitution in the production function is larger than one, the capital share converges to one in

Good communication is of utmost importance in all forms of cancer care and especially so in the palliative context. To render the ungraspable graspable, metaphors are frequently used drawing on their capacity to capture the intangible in terms of more familiar experiences. For instance, to die from cancer can be described as ’coming to the end of a life journey’ or ’losing a battle’. Metaphors are

In Parkinson’s disease, long-term dopamine replacement therapy is complicated by the appearance of L-DOPA-induced dyskinesia (LID). One major hypothesis is that LID results from an aberrant transcriptional program in striatal neurons induced by l-DOPA and triggered by the activation of ERK. To identify these genes, we performed transcriptome analyses in the striatum in 6-hydroxydopamine-lesioned m

In advanced Parkinson's disease, l-DOPA treatment causes the appearance of abnormal involuntary movements or l-DOPA-induced dyskinesia (LID). LID results in part from l-DOPA-induced activation of extracellular signal-regulated kinase (ERK) in the dopamine-denervated striatum. Activated ERK triggers nuclear responses, including phosphorylation of mitogen- and stress-activated protein kinase 1 (MSK1
