Measurement of the transverse momentum distribution of W bosons in pp collisions at root s=7 TeV with the ATLAS detector

This paper describes a measurement of the W boson transverse momentum distribution using ATLAS pp collision data from the 2010 run of the LHC at root s = 7 TeV, corresponding to an integrated luminosity of about 31 pb(-1). Events form both W -> e nu and W -> mu nu are used, and the transverse momentum of the W candidates is measured through the energy deposition in the calorimeter from the recoil

Characterizing the Astrometric Errors in the Gaia Catalogue

Accurate characterization of the errors in the global astrometric solution for Gaia is essential for making optimal use of the catalogue data. We investigate the structure of the covariance between the estimated astrometric parameters by studying the properties of the astrometric least squares solution. We find that astrometric errors can be separated in a star and an attitude part, due to the est

The Pernicious Effects of Contaminated Data in Risk Management

Banks hold capital to guard against unexpected surges in losses and long freezes in financial markets. The minimum level of capital is set by banking regulators as a function of the banks’ own estimates of their risk exposures. As a result, a great challenge for both banks and regulators is to validate internal risk models. We show that a large fraction of US and international banks uses contamina

Transgenic Expression of Laminin α1 Chain Does Not Prevent Muscle Disease in the mdx Mouse Model for Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is a severe neuromuscular disorder, and one of the most frequently encountered, but one for which there is as yet no treatment. Laminin-111 protein therapy was recently shown to be a promising approach to prevent muscle disease in the mdx mouse model of DMD. The present study demonstrated that transgenic expression of laminin α1 chain in mdx animals, resulting in

Review: The future of cell therapies and brain repair: Parkinson's disease leads the way.

During the past 40 years brain tissue grafting techniques have been used both to study fundamental neurobiological questions and to treat neurological diseases. Motor symptoms of Parkinson's disease are largely due to degeneration of midbrain dopamine neurones. Because the nigrostriatal pathology is relatively focused anatomically, Parkinson's disease is considered the ideal candidate for brain re

Radiological and clinical outcome of screw placement in adolescent idiopathic scoliosis: evaluation with low-dose computed tomography.

Posterior corrective surgery using "all pedicle screw construct" carries risk of neurovascular complications. The study aims were to assess the screw placement in patients with adolescent idiopathic scoliosis using CT with low-radiation dose, and to evaluate the clinical outcome in patients with misplaced pedicle screws. CTs of 49 consecutive patients (873 screws, 79% thoracic) were retrospectivel

The Neoarchaean Storø Supracrustal Belt, Nuuk region, southern West Greenland : an arc-related basin with continent-derived sedimentation

We present new major and trace element data, as well as Sm–Nd isotope compositions for Archaean supracrustal rocks and a gabbro-anorthosite complex from the island of Storø in Godthåbsfjord, southern West Greenland. We also provide new U–Pb isotope data for zircon extracted from these rocks. The Storø rocks have experienced amphibolite facies metamorphism, and the entire sequence forms an east-dip

Hospital costs for robot-assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy.

OBJECTIVE: To compare robot-assisted laparoscopy and laparotomy for radical hysterectomy and pelvic lymphadenectomy in terms of hospital costs. METHODS: Consecutive women undergoing radical hysterectomy and pelvic lymphadenectomy as a sole procedure between January 2001 and February 2012 were included. We compared OR times, hospital stay, procedure specific costs, blood transfusions and cost for r

Connect the Dots: Managing the Fragmentation of Global Climate Governance

The debate about post-2012 global climate governance has been framed largely by proponents and opponents of the policymaking process established by the United Nations Framework Convention on Climate Change (UNFCCC). In light of the proliferation of institutions governing some aspects of climate change, analysts have asked whether a centralized or a polycentric climate governance architecture will

Verification of motion induced thread effect during tomotherapy using gel dosimetry

The purpose of the study was to evaluate how breathing motion during tomotherapy (Accuray, CA, USA) treatment affects the absorbed dose distribution. The experiments were carried out using gel dosimetry and a motion device simulating respiratory-like motion (HexaMotion, ScandiDos, Uppsala, Sweden). Normoxic polyacrylamide gels (nPAG) were irradiated, both during respiratory-like motion and in a st

Do EPA Administrators Recommend Environmental Policies That Citizens Want?

We investigate whether Swedish Environmental Protection Agency (EPA) administrator recommendations regarding improvements in environmental quality differ from citizen preferences. This is done by conducting identical choice experiments on both citizens and administrators at the EPA. The administrators were asked to choose the alternatives they would recommend as a policy, while the citizens were a

Global data set of biogenic VOC emissions calculated by the MEGAN model over the last 30 years

The Model of Emissions of Gases and Aerosols from Nature (MEGANv2.1) together with the Modern-Era Retrospective Analysis for Research and Applications (MERRA) meteorological fields were used to create a global emission data set of biogenic volatile organic compounds (BVOC) available on a monthly basis for the time period of 1980-2010. This data set, developed under the Monitoring Atmospheric Compo

Stratified structural and epistemic aspects of the care manager's discretion : A theoretical approach to social work related to older people's potential relocation to a residential home

Det övergripande syftet med artikeln är att med hjälp av en teoretisk utgångspunkt beskriva, analysera och försöka förstå varför biståndshandläggarna i sin dagliga yrkesutövning normaliserar en restriktiv hållning när äldre personer överväger en flytt till ett särskilt boende. Medan tidigare forskning i stor utsträckning har uppmärksammat på vilket sätt biståndshandläggarna tillämpar en restriktivBy applying a theoretical point of departure, the overarching aim of this article is to describe, analyze, and try to understand why care managers in their everyday occupational practice normalize the restrictive approach when older people consider relocation to a residential home. While earlier research to a large extent has drawn attention to how the care managers carry out the restrictive appro

Models of Workplace Incivility: The Relationships to Instigated Incivility and Negative Outcomes

The aim of the study was to investigate workplace incivility as a social process, examining its components and relationships to both instigated incivility and negative outcomes in the form of well-being, job satisfaction, turnover intentions, and sleeping problems. The different components of incivility that were examined were experienced and witnessed incivility from coworkers as well as supervis

The Satisfaction with Daily Occupations (SDO-13) Scale: Psychometric Properties among Clients in Primary Care in Sweden.

This article describes the results to expand and develop the use of the Satisfaction with Daily Occupations (SDO-13) Scale. Data were collected in primary care before (I) and after intervention (II) among clients with stress-related disorders and musculoskeletal pain. The Cronbach's alpha values of the SDO-13 Scale were 0.80 and 0.88. Convergent validity was assessed against global occupational sa

In-Plane Magnetic Anisotropy and Temperature Dependence of Switching Field in (Ga, Mn)As Ferromagnetic Semiconductors

We explore the magnetic anisotropy of GaMnAs ferromagnetic semiconductor by Planar Hall Effect (PHE) measurements. Using low magnitude of applied magnetic field (i.e., when the magnitude H is smaller than both cubic Hc and uniaxial Hu anisotropy field), we have observed various shapes of applied magnetic field direction dependence of Planar Hall Resistance (PHR). In particular, in two regions of t

Modeling Charge Preparation And Combustion In Diesel Fuel, Ethanol, And Dual-Fuel PCCI Engines

In this work, multi-dimensional computational fluid dynamics modeling predictions are compared for three different methods of achieving high-efficiency, low NOT, and soot premixed charge compression ignition (PCCI) combustion. The first method is early injection, highly dilute (i.e., low oxygen concentration), diesel fuel PCCI operation. In this method, the oxygen concentration is reduced to exten

B cell lymphoma and myeloma in murine Gaucher's disease

Multiple myeloma and B cell lymphoma are leading causes of death in Gaucher's disease but the nature of the stimulus driving the often noted clonal expansion of immunoglobulin-secreting B cells and cognate lymphoid malignancy is unknown. We investigated the long-term development of B cell malignancies in an authentic model of non-neuronopathic Gaucher's disease in mice: selective deficiency of -gl
