A search for vector-like quarks and excited quarks in events containing a top quark and a W boson in the final state is reported here. The search is based on 20.3 fb−1 of proton-proton collision data taken at the LHC at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector. Events with one or two leptons, and one, two or three jets are selected with the additional requirement that at lea

Background: Comprehensive geriatric assessment (CGA) represent an important component of geriatric acute hospital care for frail older people, secured by a multidisciplinary team who addresses the multiple needs of physical health, functional ability, psychological state, cognition and social status. The primary objective of the pilot study was to determine feasibility for recruitment and retentio

A search for a Higgs boson produced via vector-boson fusion and decaying into invisible particles is presented, using 20.3 fb−1of proton-proton collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the LHC. For a Higgs boson with a mass of 125 GeV, assuming the Standard Model production cross section, an upper bound of 0.28 is set on the branching fraction of H → inv

Abstract: A search for a high-mass Higgs boson H is performed in the H → WW → ℓνℓν and H → WW → ℓνqq decay channels using pp collision data corresponding to an integrated luminosity of 20.3 fb−1 collected at s=8(Formula presented.) TeV by the ATLAS detector at the Large Hadron Collider. No evidence of a high-mass Higgs boson is found. Limits on σH × BR(H → WW) as a function of the Higgs boson mass

Central neuraxial blocks (CNB: epidural, spinal and their combinations) and other spinal pain procedures can cause serious harm to the spinal cord in patients on antihaemostatic drugs or who have other risk-factors for bleeding in the spinal canal. The purpose of this narrative review is to provide a practise advisory on how to reduce risk of spinal cord injury from spinal haematoma (SH) during CN

Abstract: A search is conducted for new physics in multijet final states using 3.6 inverse femtobarns of data from proton-proton collisions at (Formula presented.) TeV taken at the CERN Large Hadron Collider with the ATLAS detector. Events are selected containing at least three jets with scalar sum of jet transverse momenta (HT) greater than 1 TeV. No excess is seen at large HTand limits are prese

The ubiquitin (Ub) proteasome system and Ub signalling networks are crucial to cell biology and disease development. Deubiquitylases (DUBs) control cell signalling by removing mono-Ub and polyubiquitin chains from substrates. DUBs take part in almost all processes that regulate cellular life and are frequently dysregulated in disease. We have catalogued 99 currently known DUBs in the human genome

This paper presents the process and results of a set of studies within the ABBI EU project, with the general aim to co-design wearable technology (an audio bracelet) together with visually impaired children, starting at a young age. The authors discuss user preferences related to sounds and tactile materials and present the results of a focus group with very young visually-impaired children under

Background: Liver resection for colorectal liver metastases offers a 5-year survival rate of 25%–58%. This study aimed to analyze whether patients with colorectal liver metastases undergo resection to an equal extent and whether selection factors play a role in the selection process. Material and Methods: Data were retrieved from the Swedish Colorectal Cancer Registry (2007–2011) for colorectal ca

Microbial growth in soil is mostly limited by lack of carbon (C). However, adding fresh, C-rich litter can induce nitrogen (N) limitation. We studied the effect of alleviating C and N limitation in high-pH (> 8) soils, soils expected to favor bacterial over fungal growth. Nitrogen limitation was induced by incubating soils amended with C-rich substrate (starch or straw) for 4 weeks. Limiting nutri

I detta kapitel diskuteras kritiskt två relaterade tendenser i filosofiska teorier om mänskliga rättigheter. Den första handlar om synen på rättighetsinnehavaren. Mänskliga rättigheter har kommit att betraktas som något som människor ”har” och då uppstår frågan vad det är med människor som gör dem till rättighetsinnehavare. Ett vanligt svar är att människor besitter den moraliska värdighet som gör

In the article I investigate the differences between Ansel Adams' and Jerry Uelsmann's use of nature in their respective photography. Through their attitudes, approaches to, and involvement with nature their different relations to the photographic medium and the creative process unfold. Uelsmann's departure from the straight photographic tradition - that Ansel Adams came to symbolize - is in the a

In terms of genome size, the hepatitis B virus is the smallest virus known to infect humans and its compactness with multiple overlapping reading frames puts restraints on the emergence of mutations. In the papers included in this thesis we aimed to investigate genetic variation within the precore and core promoter region and to describe the origin, spread and diversification of HBV genotype A. We

Stroke has multiple etiologies, but the underlying genes and pathways are largely unknown. We conducted a multiancestry genome-wide-association meta-analysis in 521,612 individuals (67,162 cases and 454,450 controls) and discovered 22 new stroke risk loci, bringing the total to 32. We further found shared genetic variation with related vascular traits, including blood pressure, cardiac traits, and

Novel soil remediation equipment based on electro-kinetic geosynthetics (EKG) was developed for in situ isolation of metals from paddy soil. Two mutually independent field plot experiments A and B (with and without electric current applied) were conducted. After saturation using ferric chloride (FeCl3) and calcium chloride (CaCl2), soil water drainage capacity, soil cadmium (Cd) removal performanc

Background: Labor subjects the fetus to an hypoxic episode and concomitant adrenomodullary catecholamine surge that may provide protection against the hypoxic insult. The beta1-adrenergic agonist dobutamine protects against hypoxia/aglycemia induced neuronal damage. We aimed to identify the associated protective biological processes involved. Results: Hippocampal slices from 6 days old mice showed

Background: Differences in stroke care and health outcomes between men and women are debated. The objective of this study was to explore the relationship between patients' sex and post-stroke health outcomes and received care in a Swedish setting. Methods: Patients with a registered diagnosis of acute intracerebral hemorrhage (ICH) or ischemic stroke (IS) within regional administrative systems (IC

FKBP12 (FK506 binding protein 12 kDa) is an important drug target. Nuclear magnetic resonance (NMR) order parameters, describing amplitudes of motion on the pico- to nanosecond time scale, can provide estimates of changes in conformational entropy upon ligand binding. Here we report backbone and methyl-axis order parameters of the apo and FK506-bound forms of FKBP12, based on 15N and 2H NMR relaxa

The problem of low-rank approximation with convex constraints, which appears in data analysis, system identification, model order reduction, low-order controller design and low-complexity modelling is considered. Given a matrix, the objective is to find a low-rank approximation that meets rank and convex constraints, while minimizing the distance to the matrix in the squared Frobenius norm. In man
