Massive star clusters are observed in galaxies spanning a broad range of luminosities and types, and are assumed to form in dense gas-rich environments. Using a parsec-resolution hydrodynamical simulation of an isolated gas-rich low-mass galaxy, we discuss here the non-linear effects of stellar feedback on the properties of star clusters with a focus on the progenitors of nuclear clusters. Our sim

We combine parallaxes from the first Gaia data release with the spectrophotometric distance estimation framework for stars in the fifth RAVE survey data release. The combined distance estimates aremore accurate than either determination in isolation - uncertainties are on average two times smaller than for RAVE-only distances (three times smaller for dwarfs), and 1.4 times smaller than TGAS parall

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

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

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

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

Context: Value stream mapping (VSM) as a tool for lean development has led to significant improvements in different industries. In a few studies, it has been successfully applied in a software engineering context. However, some shortcomings have been observed in particular failing to capture the dynamic nature of the software process to evaluate improvements i.e. such improvements and target value

Heterogeneous systems comprising sets of inherent subsystems are challenging to integrate. In particular, testing for interoperability and conformance is a challenge. Furthermore, the complexities of such systems amplify traditional testing challenges.We explore (1) which techniques are frequently discussed in literature in context of heterogeneous system testing that practitioners use to test the

[Context and motivation] Quality requirements (QRs) are inherently difficult to manage as they are often subjective, context-dependent and hard to fully grasp by various stakeholders. Furthermore, there are many sources that can provide input on important QRs and suitable levels. Responding timely to customer needs and realizing them in product portfolio and product scope decisions remain the main

Many agricultural technology interventions that aim to improve farmers’ livelihoods focus on households as the unit of analysis and ignore gender roles that entail different benefits and costs for different household members. Agricultural projects have shown limited success where gender roles and relations were ignored and thus more gender sensitive research is needed in agricultural technology de

Background: Software testing benefits from the usage of Knowledge Management (KM) methods and principles. Thus, there is a need to adopt KM to the software testing core processes and attain the benefits that it provides in terms of cost, quality, etc. Aim: To investigate the usage and implementation of KM for software testing. The major objectives include 1. To identify various software testing as

Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly. Here, the past and present distribution Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly.

Recent research has shed light on the various tradeoffs involved in carbon forestry, i.e. the pursuit of international forestry projects to help mitigate climate change. This article contributes to these debates by highlighting the importance of resource quality and degradation in evaluating project benefits and tradeoffs. Focusing on the case of an industrial tree plantation in Uganda, the Kachun

Amyloid protein aggregation results in major disturbances of cellular processes in humans. The most common amyloid-related disorders are Alzheimer´s disease and Parkinson´s disease. Parkinson´s disease is charaterized by the formation of protein-rich aggregates that are deposited in neurons, termed Lewy bodies and Lewy neurites. The main component identified in these protein-rich deposits is the pAmyloid protein aggregation results in major disturbances of cellular processes in humans.
