In models of dust growth in protoplanetary discs focus is typically on coagulation, a mechanism which unfortunately seems incapable of forming particles larger than centimeters. The main reasons for this are that collisions between larger particles lead to bouncing or fragmentation rather than sticking, and that particles approaching meter-sizes drift radially inwards in the disc due to interactio

BACKGROUND: High blood pressure contributes to organ damage. However, during the past two decades there have been great advances in the medical treatment of hypertension. Technical progress has also made it easier to visualize organ damage. Hence we found it of interest to examine heart, brain and retina in a group of middle-aged treated hypertensives, comparing the results with those from a group

This study analyzes how risk attitudes influence the agricultural productivity of men and women in a sub- Saharan African country, Burkina Faso. By using a large representative panel survey of farmers, the results show that as female farmers increase risk taking, the productivity of female-owned plots goes down. The study controls for various socio-economic factors and explores how the diversity o

The application of Agent-Based Modeling and Simulation (ABMS) has few established guidelines and often suffers from insufficient model documentation. We assess the prevalence of best practices associated with different types of model documentation in light of the European Union’s AI Act (AI Act). Our analysis reveals that best practices are often implemented together but ultimately reinforce the p

The stability of the Nyström method for the Sherman–Lauricella equation on piecewise smooth closed simple contour $\Gamma$ is studied. It is shown that in the space $L_2$ the method is stable if and only if certain operators associated with the corner points of $\Gamma$ are invertible. If $\Gamma$ does not have corner points, the method is always stable. Numerical experiments show the transformati

Resource extraction and processing contribute to more than 90% of biodiversity loss and water scarcity and about 50% of climate impacts globally. Moving towards a sustainable resource use is fundamental for reducing environmental impact. Resource use is often considered within the framework of the Circular Economy, a concept that has been widely adopted as a key strategy to meet this challenge. In

With a far going protection of IP rights, the EU aims to protect the assets of companies which invested in innovative products. If the EU framework provides a far going mechanism of protection of IP rights, the complexity and the cost of this mechanism have been a barrier to the access of IP rights. In additional to these structural issues, the digital revolution introduced new challenges for the

Recent work by Nissen and Schuster have found two distinct populations of halo stars with -1<5 alpha [Fe/H] -0<5. Both populations are kinematically selected to be halo stars. The differences between the two groups are the alpha -elemental abundances and the [Na/Fe] and [Ni/Fe] ratios. From angular momentum space, we can see that the majority of these stars do not show any extreme kinematic indica
