System requirements-OSS components: matching and mismatch resolution practices – an empirical study

Developing systems by integrating Open Source Software (OSS) is increasingly gaining importance in the software industry. Although the literature claims that this approach highly impacts Requirements Engineering (RE) practices, there is a lack of empirical evidence to demonstrate this statement.

Evidence for single top-quark production in the s-channel in proton–proton collisions at √s=8 TeV with the ATLAS detector using the Matrix Element Method

This Letter presents evidence for single top-quark production in the s-channel using proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. The analysis is performed on events containing one isolated electron or muon, large missing transverse momentum and exactly two b-tagged jets in the final state. The analysed data set corresponds

Combination of searches for WW, WZ, and ZZ resonances in pp collisions at √s=8 TeV with the ATLAS detector

The ATLAS experiment at the CERN Large Hadron Collider has performed searches for new, heavy bosons decaying to WW, WZ and ZZ final states in multiple decay channels using 20.3 fb−1 of pp collision data at s=8 TeV. In the current study, the results of these searches are combined to provide a more stringent test of models predicting heavy resonances with couplings to vector bosons. Direct searches

A computer simulation model of the natural history and economic impact of chronic obstructive pulmonary disease

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is a major health problem with high societal costs. The Global Initiative for Chronic Lung Disease (GOLD) has identified a need for health economics data for COPD. For chronic diseases, such as COPD, where the natural history of disease is lifetime, a modeling approach for economic evaluation may be more realistic than prospective, piggy-back

Dijet production in √s=7 TeV pp collisions with large rapidity gaps at the ATLAS experiment

A 6.8 nb−1 sample of pp collision data collected under low-luminosity conditions at s=7TeV by the ATLAS detector at the Large Hadron Collider is used to study diffractive dijet production. Events containing at least two jets with pT>20GeV are selected and analysed in terms of variables which discriminate between diffractive and non-diffractive processes. Cross sections are measured differentially

Constraints on non-Standard Model Higgs boson interactions in an effective Lagrangian using differential cross sections measured in the H → γγ decay channel at √s=8 TeV with the ATLAS detector

The strength and tensor structure of the Higgs boson's interactions are investigated using an effective Lagrangian, which introduces additional CP-even and CP-odd interactions that lead to changes in the kinematic properties of the Higgs boson and associated jet spectra with respect to the Standard Model. The parameters of the effective Lagrangian are probed using a fit to five differential cross

Endogenous insensitivity to the Orco agonist VUAA1 reveals novel olfactory receptor complex properties in the specialist fly Mayetiola destructor

Insect olfactory receptors are routinely expressed in heterologous systems for functionalcharacterisation. It was recently discovered that the essential olfactory receptor co-receptor (Orco)of the Hessian fly, Mayetiola destructor (Mdes), does not respond to the agonist VUAA1, whichactivates Orco in all other insects analysed to date. Here, using a mutagenesis-based approach weidentified three res

Bronchial extracellular matrix from COPD patients induces altered gene expression in repopulated primary human bronchial epithelial cells

Chronic obstructive pulmonary disease (COPD) is a serious global health problem characterized by chronic airway inflammation, progressive airflow limitation and destruction of lung parenchyma. Remodeling of the bronchial airways in COPD includes changes in both the bronchial epithelium and the subepithelial extracellular matrix (ECM). To explore the impact of an aberrant ECM on epithelial cell phe

Synthesis of armchair graphene nanoribbons from the 10,10′-dibromo-9,9′-bianthracene molecules on Ag(111) : The role of organometallic intermediates

We investigate the bottom-up growth of N = 7 armchair graphene nanoribbons (7-AGNRs) from the 10,10′-dibromo-9,9′-bianthracene (DBBA) molecules on Ag(111) with the focus on the role of the organometallic (OM) intermediates. It is demonstrated that DBBA molecules on Ag(111) are partially debrominated at room temperature and lose all bromine atoms at elevated temperatures. Similar to DBBA on Cu(111)

Simultaneous multispectral imaging of flame species using Frequency Recognition Algorithm for Multiple Exposures (FRAME)

Imaging the interaction between different combustion species under turbulent flame conditions requires methods that both are extremely fast and provide means to spectrally separate different signals. Current experimental solutions to achieve this often rely on using several cameras that are time-gated and/or equipped with different spectral filters. In this work we explore a technique called Frequ

Perceived child eating behaviours and maternal migrant background

The Child Eating Behaviour Questionnaire (CEBQ) is a well-established instrument in the study of obesity-related eating behaviours among children. However, research using the CEBQ in multicultural samples is limited. This study aims to identify and examine differences in child eating behaviours as reported by Swedish-born and non-Swedish-born mothers living in Sweden. Mothers (n = 1310, 74 countri

Structural stability of SoPIP2;1 aquaporin under reconstitution in polymersomes

In the present paper we show the preparation of polymersomes using ABA triblock copolymers with poly(dimethylsiloxane) and poly(2-methyloxazoline) blocks with the incorporation of SoPIP2;1 aquaporin in their structure. The presence of the protein in the polymersome membrane was demonstrated using imaging techniques, and the conformation of the protein into the membranes was assessed using Raman sp

Enhanced nitrate-nitrogen removal by modified attapulgite-supported nanoscale zero-valent iron treating simulated groundwater

Attapulgite (or palygorskite) is a magnesium aluminium phyllosilicate. Modified attapulgite-supported nanoscale zero-valent iron (NZVI) was created by a liquid-phase reduction method and then applied for nitrate-nitrogen (NO3-N) removal (transformation) in simulated groundwater. Nanoscale zero-valent iron was sufficiently dispersed on the surface of thermally modified attapulgite. The NO3-N remova

Sensors of Succinate : Neural Stem Cell Grafts Fight Neuroinflammation

In this issue of Cell Stem Cell, Peruzzotti-Jametti et al. (2018) demonstrate how neural stem cells, transplanted in a mouse model of multiple sclerosis, respond to extracellular succinate and modulate neuroinflammation by releasing anti-inflammatory prostaglandin E2 and scavenging succinate. This mechanism reduces CNS damage and ameliorates motor impairment. In this issue of Cell Stem Cell, Peruz
