Two-particle pseudorapidity correlations are measured in sNN=2.76TeVPb+Pb, sNN=5.02TeVp+Pb, and s=13TeVpp collisions at the Large Hadron Collider (LHC), with total integrated luminosities of approximately 7μb-1, 28 nb-1, and 65 nb-1, respectively. The correlation function CN(η1,η2) is measured as a function of event multiplicity using charged particles in the pseudorapidity range |η|

Skrift utgiven den 1 maj 1910, i samband med återöppnandet av de nyordnande avdelningarna av universitetets konstmuseum, målerisamlingen i universitetets övervåning och skulptursamlingen i bottenvåningen (under aulan).

High-precision measurements by the ATLAS Collaboration are presented of inclusive W+→ ℓ+ν, W-→ ℓ-ν¯ and Z/ γ∗→ ℓℓ (ℓ= e, μ) Drell–Yan production cross sections at the LHC. The data were collected in proton–proton collisions at s=7TeV with an integrated luminosity of 4.6fb-1. Differential W+ and W- cross sections are measured in a lepton pseudorapidity range | ηℓ| < 2.5. Differential Z/ γ∗ cross se

Results of a search for physics beyond the Standard Model in events containing an energetic photon and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. As the number of events observed in data, corresponding to an integrated luminosity of 36.1 fb- 1 of proton–proton collisions at a centre-of-mass energy of 13TeV, is in agreement with the Standard

The development of large, software-intensive systems is a complex undertaking that we generally tackle by a divide and conquer strategy. Companies thereby face the challenge of coordinating individual aspects of software development, in particular between requirements engineering (RE) and software testing (ST). A lack of REST alignment can not only lead to wasted effort but also to defective softw

Nuytsia floribunda, was first described in print by Jacques Labillardière in a work from 1805 – Novae Hollandiae Plantarum Specimen – under the name of Loranthus floribundus. The name aimed at describing the colorful flowering, on a tree unique in the plant world through its hemiparastic way of living, developing of haustoria not seen elsewhere. Labillardière had observed the species on a journey

Software Engineering activities are information intensive. Research proposes Information Retrieval (IR) techniques to support engineers in their daily tasks, such as establishing and maintaining traceability links, fault identification, and software maintenance. We describe an engineering task, test case selection, and illustrate our problem analysis and solution discovery process. The objective o

During the past decade it has become evident that immunological, infl ammatory and vascular processes play an important role in the etiology and pathogenesis of various neuro-degenerative diseases. Alzheimer's disease (AD) is a complex and genetically heterogeneous disease that is the most common form of dementia and aff ects up to 15 million individuals worldwide. Th e presenting pathology of AD

The worldwide growing demand for whey proteins and derivatives requires more efficient and sustainable whey protein production processes. Whey is an important by-product from cheese manufacturing. In whey industry membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis are well-established to concentrate, fractionate and purify whey proteins as well as whey

Fouling is a constant challenge in membrane-based technologies. As conventional fouling monitoring and control methods are often based on process performance or product quality, they might reveal fouling so late that it has already damaged the membrane in severe and non-reversible way. Thus, surface sensitive online monitoring techniques capable of providing early warning capacity and information

Measurements of jet activity in top-quark pair events produced in proton–proton collisions are presented, using 3.2 fb- 1of pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events are chosen by requiring an opposite-charge eμ pair and two b-tagged jets in the final state. The normalised differential cross-sections of top-quark p

To assess the benefits of introducing Agile practices, it is important to get a clear understanding of the baseline situation, i.e. the situation before their introduction. Without a clear baseline, we cannot properly assess the extent of impacts, both positive and negative, of introducing Agile practices. This paper provides a preliminary guideline to help researchers in capturing and reporting b

Software developing organizations strive to achieve flexibility to maintain a competitive advantage. There is no common understanding of what characterize flexibility for a software organization beyond the scope of the software product. Without a common understanding, it is difficult to evaluate the degrees of flexibility of software development approaches. The aim of this literature review is to

Periodic boundary conditions (PBC) are well suited to describe repetitive structures in space, yet flawed for isotropic setups in which it is commonly used. We present an approach based on exploiting the congruency of a unit cell which combines the periodic nature of PBC with isotropy of an alternating cell. By applying these isotropic periodic boundary conditions (IPBC) to the standard Ewald summ

Purpose: This study examined if speed reduction effects from animal-vehicle collision (AVC) countermeasures are merely local or do extend to a wider area, and what implications the results have on road planning practice regarding AVCs. Methods: Twenty-five drivers drove repeatedly on a 9-km long road stretch in a high-fidelity driving simulator. The development of vehicle speed in the surrounding

DevOps as a new way of thinking for software development and operations has received much attention in the industry, while it has not been thoroughly investigated in academia yet. The objective of this study is to characterize DevOps by exploring its central components in terms of principles, practices and their relations to the principles, challenges of DevOps adoption, and benefits reported in t

Cisterna magna cannulation (CMc) is a straightforward procedure that enables direct access to the cerebrospinal fluid (CSF) without operative damage to the skull or the brain parenchyma. In anesthetized rodents, the exposure of the dura mater by blunt dissection of the neck muscles allows the insertion of a cannula into the cisterna magna (CM). The cannula, composed either by a fine beveled needle

We test asteroseismic radii of Kepler main-sequence and subgiant stars by deriving their parallaxes which are compared with those of the first Gaia data release. We compute radii based on the asteroseismic scaling relations as well as by fitting observed oscillation frequencies to stellar models for a subset of the sample, and test the impact of using effective temperatures from either spectroscop

In recent years, there has been significant shift from rigid development (RD) toward agile. However, it has also been spotted that agile methodologies are hardly ever followed in their pure form. Hybrid processes as combinations of RD and agile practices emerge. In addition, agile adoption has been reported to result in both benefits and limitations. This exploratory study (a) identifies developme
