Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period

This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge

Cellulose gelation in NaOH solutions is due to cellulose crystallization

Abstract: Cellulose gelation in 2 M NaOH aqueous solution was followed by time resolved turbidity and rheology measurements. The kinetics of gelation is observed to change from several hours down to few seconds when the temperature is increased from 25 to 30 °C. The increase of turbidity upon gelation demonstrates the formation of larger cellulose aggregates, while wide angle X-ray scattering data

Diversity mechanisms and MIMO throughput performance of a compact six-port dielectric resonator antenna array

This paper demonstrates multiple-input-multiple-output (MIMO) throughput performance of a six-port dielectric resonator antenna (DRA) array for Wireless-LAN applications in a measured indoor office environment when a six-port dual-polarized patch array is used at the transmitter. The throughput was obtained using an IEEE802.11n/Draft 5.00 simulator for measured channels with different antenna and

Quality of life in patients with advanced epithelial ovarian cancer (EOC) randomized to maintenance pazopanib or placebo after first-line chemotherapy in the AGO-OVAR 16 trial. Measuring what matters-patient-centered end points in trials of maintenance therapy

Background: Health-related quality of life (HRQoL) was a secondary end point in AGO-OVAR 16, which randomized 940 patients with EOC after first-line chemotherapy to maintenance pazopanib (PZ) or placebo (P). Additional post hoc analyses were carried out to investigate additional patient-centered end points. Patients and methods: HRQoL was measured with EORTC-QLQ-C30, QLQ-OV28 and EQ-5D-3L. Pre-spe

Prenatal phthalate exposure was associated with croup in Swedish infants

Aim: This study examined whether prenatal phthalate exposure was associated with lower or upper airway inflammation in infants. Methods: From 2007 to 2010, we used liquid chromatography-tandem mass spectrometry, adjusted for creatinine, to analyse 14 phthalate metabolites and one phthalate replacement in the urine of 1062 Swedish mothers at a median of 10 weeks of pregnancy. This was used to deter

Centrality, rapidity, and transverse momentum dependence of isolated prompt photon production in lead-lead collisions at sNN =2.76 TeV measured with the ATLAS detector

Prompt photon production in sNN=2.76-TeV Pb+Pb collisions has been measured by the ATLAS experiment at the Large Hadron Collider using data collected in 2011 with an integrated luminosity of 0.14 nb-1. Inclusive photon yields, scaled by the mean nuclear thickness function, are presented as a function of collision centrality and transverse momentum in two pseudorapidity intervals, |η|

Search for new phenomena in events with at least three photons collected in pp collisions at √s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in events with at least three photons are reported. Data from proton– proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb−1, were collected with the ATLAS detector at the LHC. The observed data are well described by the Standard Model. Limits at the 95 % confidence level on new phenomena are presented bas

Identification and characterization of DNA sequence variants associated with multiple myeloma

Multiple myeloma (MM) is the second most common hematologic malignancy. The disease is characterized by an uncontrolled growth of malignant plasma cells in the bone marrow, producing a monoclonal immunoglobulin (“M protein”) that can be detected in peripheral blood. Clinically, MM is characterized by bone marrow failure, lytic bone lesions, hypercalcemia, and kidney failure. It is preceded by mono

Climate change and anthropogenic intervention impact on the hydrologic anomalies in a semi-arid area : Lower Zab River Basin, Iraq

Climate change impact, drought phenomena and anthropogenic stress are of increasing apprehension for water resource managers and strategists, particularly in arid regions. The current study proposes a generic methodology to evaluate the potential impact of such changes at a basin scale. The Lower Zab River Basin located in the north of Iraq has been selected for illustration purposes. The method h

Grassroots practices of citizenship and politicization in the urban : the case of right to the city initiatives in Barcelona

This article aims to produce an analysis of the politicization of the citizens after Spain’s Indignados movement from a citizenship framework. The article suggests that claiming the right to the city involves more than issues of access to urban amenities: it is also about claiming the right to participate in the formation and transformation of the city and the right to appropriate the city center.

Fast Tracking of Fluid Invasion Using Time-Resolved Neutron Tomography

Water flow in a sandstone sample is studied during an experiment in situ in a neutron tomography setup. In this paper, a projection-based methodology for fast tracking of the imbibition front in 3D is presented. The procedure exploits each individual neutron 2D radiograph, instead of the tomographic-reconstructed images, to identify the 4D (space and time) saturation field, offering a much higher

Prevalence and associated factors for stunting among 6-12 years old school age children from rural community of Humbo district, Southern Ethiopia

Background: Stunting is one of the most serious and challenging public health problems in Ethiopia, which constitute a significant obstacle to achieving better child health outcomes. This study aimed to assess the prevalence and factors associated with stunting among 6-12 years old children in Humbo district, Southern Ethiopia. Methods: This was a cross-sectional study conducted among 633 children

Assistive technology and people : a position paper from the first global research, innovation and education on assistive technology (GREAT) summit

Assistive technology (AT) is a powerful enabler of participation. The World Health Organization’s Global Collaboration on Assistive Technology (GATE) programme is actively working towards access to assistive technology for all. Developed through collaborative work as a part of the Global Research, Innovation and Education on Assistive Technology (GREAT) Summit, this position paper provides a “stat

Sustainability of an Enhanced Recovery Program for Pancreaticoduodenectomy with Pancreaticogastrostomy

Background: Enhanced recovery program for pancreaticoduodenectomy have become standard care. Little is known about adherence rates and sustainability of the program, especially when pancreaticogastrostomy is used in reconstruction. The aim of this study was, therefore, to evaluate adherence rates and continued outcome, after implementation of an enhanced recovery program. Methods: Consecutive pati

Proteomics in Hypothermia as Adjunctive Therapy in Patients with ST-Segment Elevation Myocardial Infarction : A CHILL-MI Substudy

Cardiovascular and inflammatory biomarkers in therapeutic hypothermia have been studied in cardiac arrest, but data on patients with ST-segment elevation myocardial infarction (STEMI) treated with therapeutic hypothermia are currently unavailable. A multiplex proximity extension assay allowed us to measure 157 cardiovascular disease (CVD) and inflammatory disease-related biomarkers in patients fro

Two-dimensional Fano lineshapes : Excited-state absorption contributions

Fano interferences in nanostructures are influenced by dissipation effects as well as many-body interactions. Two-dimensional coherent spectroscopies have just begun to be applied to these systems where the spectroscopic signatures of a discrete-continuum structure are not known. In this article, we calculate the excited-state absorption contribution for different models of higher lying excited st
