Measurement of the cross section for top-quark pair production in pp collisions at root s=7 TeV with the ATLAS detector using final states with two high-p(T) leptons

A measurement is reported of the production cross section of top-quark pairs (t (t) over bar) in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the LHC. Candidate events have a signature consistent with containing two isolated leptons, large missing transverse momentum, and at least two jets. Using a data sample corresponding to an integrated lumin

Isotope labeled internal standards (ILIS) as a basis for quality control in clinical studies using plasma samples

For clinical proteomic studies the availability of high quality biofluid samples such as human blood plasma are extremely important. In this study we have investigated the stability of human plasma samples by spiking stable isotope-labeled peptides into the plasma and monitoring their degradation under different storage conditions. FPA-1, C4A and C3f were synthesized with isotopically labeled amin

Time-dependent motor properties of multipedal molecular spiders

Molecular spiders are synthetic biomolecular walkers that use the asymmetry resulting from cleavage of their tracks to bias the direction of their stepping motion. Using Monte Carlo simulations that implement the Gillespie algorithm, we investigate the dependence of the biased motion of molecular spiders, along with binding time and processivity, on tunable experimental parameters, such as number

LES with acoustics and PSI for deforming plates in gas flow

This concerns Flow Induced Vibrations (Fly) in nuclear reactors and numerical analysis of such. Special attention is paid to structural excitation by sound generated remotely and turbulent flow around the structure. One hypothesis was that these phenomena can interact, so that the structure accumulates more energy from the flow if it also excited by sound from another source. In the studies, Fluid

Left and Right Atrial Contribution to the P-wave in Realistic Computational Models

ECG markers derived from the P-wave are used frequently to assess atrial function and anatomy, e.g. left atrial enlargement. While having the advantage of being routinely acquired, the processes underlying the genesis of the P-wave are not understood in their entirety. Particularly the distinct contributions of the two atria have not been analyzed mechanistically. We used an in silico approach to

Dual-gate induced InP nanowire diode

Semiconductor devices are heavily dependent on dopant incorporation in order to control the electrical properties. In this paper we investigate the possibility of using gates wrapped around a nanowire (NW) channel as a way of tuning the Fermi level position, in certain cases removing the need for dopants and providing a more dynamical way of setting the device properties. InP NW devices with omega

Toward a standard approach to measurement and reporting of perioperative mortality rate as a global indicator for surgery.

The proportion of patients who die during or after surgery, otherwise known as the perioperative mortality rate (POMR), is a credible indicator of the safety and quality of operative care. Its accuracy and usefulness as a metric, however, particularly one that enables valid comparisons over time or between jurisdictions, has been limited by lack of a standardized approach to measurement and calcul

Multiple paths of development: knowledge bases and institutional characteristics of the Swedish food sector

The aim of this paper is to explore the relation between the critical knowledge base of firms and how firms respond to incentives embedded in the institutional framework surrounding them. The analysis gives us a better understanding of the complex development of the food sector in Southern Sweden in the past decades. Theoretically, the paper combines concepts of path dependency and knowledge bases

Interrater reliability and construct validity of the Posture and Postural Ability Scale in adults with cerebral palsy in supine, prone, sitting and standing positions.

Objective:To evaluate reliability, internal consistency and construct validity of the Posture and Postural Ability Scale for adults with cerebral palsy.Design:Psychometric evaluation of a clinical assessment tool.Setting:Rehabilitation centres in Sweden and Iceland.Subjects:Thirty adults with cerebral palsy aged 19-22 years, six people at each level I-V of the Gross Motor Function Classification S

Production of 3-hydroxypropionic acid from 3-hydroxypropionaldehyde by recombinant Escherichia coli co-expressing Lactobacillus reuteri propanediol utilization enzymes.

3-Hydroxypropionic acid (3-HP) is an important platform chemical for the biobased chemical industry. Lactobacillus reuteri produces 3-HP from glycerol via 3-hydroxypropionaldehyde (3-HPA) through a CoA-dependent propanediol utilization (Pdu) pathway. This study was performed to verify and evaluate the pathway comprising propionaldehyde dehydrogenase (PduP), phosphotransacylase (PduL), and propiona

Reliability and validity of the assessment of neurological soft-signs in children with and without attention-deficit-hyperactivity disorder

AIM To study the value and reliability of an examination of neurological soft-signs, often used in Sweden, in the assessment of children with attentiondeficit– hyperactivity disorder (ADHD), by examining children with and without ADHD, as diagnosed by an experienced clinician using the DSM-III-R. METHOD We have examined interrater reliability (26males, nine females; age range 5y 6mo–11y), internal

Simplicity of partial skew group rings with applications to Leavitt path algebras and topological dynamics

Let A be a commutative and associative ring (not necessarily unital), G a group and α a partial action of G on ideals of A, all of which have local units. We show that A is maximal commutative in the partial skew group ring A*G if and only if A has the ideal intersection property in A*G. From this we derive a criterion for simplicity of A*G in terms of maximal commutativity and G-simplicity of A.

Geochronology and geochemical evidence for a magmatic arc setting for the Ni-Cu mineralised 1.79Ga Kleva gabbro-diorite intrusive complex, southeast Sweden

Magmatic Ni-Cu sulphide deposits are commonly associated with mafic rocks within the marginal areas of Archean or Proterozoic cratons. The Kleva Ni-Cu sulphide deposit in southeast Sweden is hosted by gabbro-diorite rocks and is sandwiched between two Palaeoproterozoic magmatic arcs: the Transscandinavian Igneous Belt (TIB) and the Oskarshamn-Jonkoping Belt (OJB). Major and trace element data corr

Gastroenteritis and the novel picornaviruses aichi virus, cosavirus, saffold virus, and salivirus in young children

Background: During the last few years many new human picornaviruses have been discovered due to advances in metagenomics and other molecular biological approaches. The clinical significance and the occurrence are only sparsely described. Objectives: To determine the epidemiology and clinical significance of infections with the novel human picornaviruses, aichi virus, cosavirus, salivirus, and saff

Homozygous factor V Leiden and double heterozygosity for factor V Leiden and prothrombin mutation.

The most common forms of familial thrombophilia are factor V Leiden (FVL) and prothrombin mutation (PTM). Homozygous FVL and PTM have long been feared conditions thought to cause high rates of morbidity and mortality. To analyse clinical features in patients with homozygous FVL and PTM, as well as patients with double heterozygosity for FVL and PTM. All patients with homozygous FVL, PTM or double

TET2 and CSMD1 genes affect SBP response to hydrochlorothiazide in never-treated essential hypertensives.

Thiazide diuretics have been recommended as a first-line antihypertensive treatment, although the choice of 'the right drug in the individual essential hypertensive patient' remains still empirical. Essential hypertension is a complex, polygenic disease derived from the interaction of patient's genetic background with the environment. Pharmacogenomics could be a useful tool to pinpoint gene varian
