Optimizing Fault Tolerance for Real-Time Systems

For the vast majority of computer systems correct operation is defined as producing the correct result within a time constraint (deadline). We refer to such computer systems as real-time systems (RTSs). RTSs manufactured in recent semiconductor technologies are increasingly susceptible to soft errors, which enforces the use of fault tolerance to detect and recover from eventual errors. However, fa

Sinnlighetens närvaro : Luther mellan kroppskult och kroppsförakt.

”Sinnlighetens närvaro – Luther mellan kroppskult och kropps- förakt” visar en annan Luther än den vi möter i media. I stället för en Luther som gör att vi arbetar för mycket visar boken en Martin Luther som bejakade sensualism och sinnlighet. Mat, vin, musik och goda vänner var ett sätt att hålla depression och tvivel borta. Kroppen var inte ett hot mot det andliga. Sexualiteten sågs som naturlig

Development of a Regional Non-dimensional Return Period Flood Model

Based on the non-dimensional approach, this study focuses on developing a model to compute design flood for specific return periods whose parameter estimations are done using the Marquardt algorithm considering peak flood data of 100 Indian catchments. The selected flood data varies for majority of the sites for a period of 10 years, and for a few sites up to 36 years; and as a preliminary process

MnAs Nanocrystals Embedded in GaAs

Magnetic properties of MnAs nanocrystals embedded in GaAs are analyzed in the frame of phenomenological model proposed by Sasaki for ferritin superparamagnets. Our calculations explain qualitatively experimental data of magnetization versus temperature; obtained according to zero-field-cooled and field-cooled protocols. They show dynamics of magnetization of MnAs nanocrystals in range of temperatu

antibody microarray analysis of directly labelled proteomes

In recent years, the antibody microarray technology has made significant progress, going from proof-of-concept designs to established high-performing technology platforms capable of targeting non-fractionated complex proteomes. In these cross-disciplinary efforts, a particular focus has lately been placed on two key technological issues: the sample and data handling. To this end, robust protocols

Detection and Identification of a Novel Lactic Acid Bacterial Flora Within the Honey Stomach of the Honeybee Apis mellifera.

This investigation concerned the question of whether honeybees collect bacteria that are beneficial for humans from the flowers that contribute to formation of their honey. Bacteria originating from the types of flowers involved, and found in different anatomic parts of the bees, in larvae, and in honey of different types, were sampled during a 2-year period. 16S rRNA sequencing of isolates and cl

PIPKs are essential for rhizoid elongation and caulonemal cell development in the moss Physcomitrella patens.

PtdIns-4,5-bisphosphate is a lipid messenger of eukaryotic cells playing critical roles in processes such as cytoskeleton organization, intracellular vesicular trafficking, secretion, cell motility, regulation of ion channels and nuclear signalling pathways. The enzymes responsible for the synthesis of PtdIns(4,5)P(2) are phosphatidylinositol phosphate kinases (PIPKs). The moss Physcomitrella pate

Seven Nation Army : med ett riff som sjungs till fotboll

This article investigates and discusses a football chant, a riff from a popular rock song entitled “Seven Nation Army” by the rock group The White Stripes from Detroit, USA. The chant is sung by supporters at football matches even in Sweden but also in corresponding social contexts, as when high school students graduate or at the pub. The survey, which was to by a reduction method compare the riff

Studies of laminin a2 chain deficient mice -muscle sparing, charaterization of Cib2 and defective spermatorgenesis

Mutations in the gene encoding laminin α2 chain, an extracellular matrix protein mainly expressed in the neuromuscular system, cause a severe form of muscular dystrophy, congenital muscular dystrophy type 1A (MDC1A). Laminin α2 chain is associated to the muscle fibers by two major receptors, where one of them, integrin α7β1, is diminished upon laminin α2 chain deficiency. The majority of the skele

Complex Metalworking in the Provinces, Rural Centres and Towns : Preliminary Results from the project "Exclusive Metalworking in Rural Settings" contextualized

The research project “Exclusive Metalworking in Rural Settings” was instigated in 2013 with funding from the Berit Wallenberg Foundation. The objective of the project is to survey sites with remains of multimetal craftsmanship of the late Iron Age and medieval periods outside urban contexts. This article aims to contextualize preliminary results from the project and evaluate its chosen source mate

Organizing for the Third Mission: Structural conditions for outreach and relevance

The authors investigate how Third Mission activities at universities, such as the outreach and technology transfer functions, are anchored in organizational structures and practices, and discuss the implications of this relationship for the success of the activities. They draw on case studies of two Swedish university colleges to illustrate the diversity of mechanisms used to achieve Third Mission

Teaching History, Learning Piety : an Alevi Foundation in Contemporary Turkey

Abstract in UndeterminedIn Turkey, a considerable number of Alevi foundations and associations work intensively with promoting Alevi visibility and rights in Turkish society. Locally, they offer educational activities where Alevis can learn, practice and reflect on their religion and culture. Based on fieldwork in one Alevi foundation in present day Istanbul, this book explores ways in which knowl

Photoelectron angular distributions for the two-photon ionization of helium by ultrashort extreme ultraviolet free-electron laser pulses

The two-photon ionization of helium atoms by ultrashort extreme-ultraviolet free-electron laser pulses, produced by the SPring-8 Compact SASE Source test accelerator, was investigated at photon energies of 20.3, 21.3, 23.0 and 24.3 eV. The angular distribution of photoelectrons generated by two-photon ionization is obtained using a velocity map imaging spectrometer. The phase-shift differences and

Contestable contexts: the transparent anchoring of contextualization in text-as-data

The article is about the criteria used to decide the relevance of particular contexts to the framework for qualitative text analysis. By conceptualizing context as something that needs to be justified, rather than identified, we argue in favour of transparency when it comes to the link between text-as-data and interpretations of text-as-data. By drawing on examples from a speech made to the Europe

Simultaneous fMRI and EEG during the Multi-Source Interference Task

fMRI and EEG are two non-invasive functional imaging techniques within cognitive neuroscience that have complementary advantages to obtain both temporal and spatial information. The multi-source interference task (MSIT) has been shown to generate robust activations of the dorsal anterior cingulate cortex (dACC) on both a single-subject level and in group averages, in fMRI studies. We have now simu

High-Level Architecture Modeling and Exploration for Streaming Applications

Multi and many core platforms are increasingly employed today to cope with the demands of modern multimedia, networking and other similar streaming applications. Selecting the best architecture for a set of such applications is complex, and without coding for each specific system, the choice is made based on designer experience. In this paper we use CAL, a dataflow language for specifying streamin

Complex evolution of the DAL5 transporter family.

BACKGROUND: Genes continuously duplicate and the duplicated copies remain in the genome or get deleted. The DAL5 subfamily of transmembrane transporter genes has eight known members in S. cerevisiae. All are putative anion:cation symporters of vitamins (such as allantoate, nicotinate, panthotenate and biotin). The DAL5 subfamily is an old and important group since it is represented in both Basidio

Towards a Health Economic Simulation Model of Type 2 Diabetes in Sweden

The aim of this thesis was to provide part of the data required in updating/developing computer simulation models (CSMs) for type 2 diabetes mellitus (T2DM) using data obtained from routine clinical practice in Sweden. In paper I, evolution of five biomarkers (i.e., HbA1c, systolic blood pressure, BMI, LDL and total to HDL cholesterol ratio) over time was estimated using data on 5,043 newly diagn
