Abstract White dwarfs (WDs) often show metal lines in their spectra, indicating accretion of asteroidal material. Our Sun is to become a WD several gigayears. Here, we examine how the solar accretes from three major small body populations: main belt asteroids (MBAs), Jovian Trojan (JTAs), and trans-Neptunian objects (TNOs). Owing mass loss during giant branch, 40% JTAs are lost but vast majorit...

Although the gender gap in earnings has been decreasing over time, it still persists in many professions such as business. Gender differences in competitiveness have been proposed as an important explanation for the remaining earnings differential. Using a laboratory experiment to measure competitiveness, this paper investigates whether this measure explains the gender gap in earnings in a samp...

Evolution of Knowledge Bases (KBs) expressed in Description Logics (DLs) has gained a lot of attention recently. Recent studies of the topic mostly focused on model-based approaches (MBAs), where the evolution of a KB results in a set of models. For KBs expressed in tractable DLs, such as those of the DL-Lite family, which we consider here, it was shown that one is faced with inexpressibility o...

Burkholderia pseudomallei is a gram-negative facultative intracellular pathogen that causes melioidosis, an invasive disease of humans and animals. To address the response of this bacterium to iron-limiting conditions, we first performed a global transcriptional analysis of RNA extracted from bacteria grown under iron-limiting and iron-rich conditions by microarrays. We focused our study on tho...

We investigate whether the gender composition of teams affect their economic performance. We study a large business game, played in groups of three, where each group takes the role of a general manager. There are two parallel competitions, one involving undergraduates and the other involving MBAs. Our analysis shows that teams formed by three women are significantly outperformed by any other ge...

Evolution of Knowledge Bases (KBs) expressed in Description Logics (DLs) proved its importance. Recent studies of the topic mostly focussed on model-based approaches (MBAs), where an evolution (of a KB) results in a set of models. For KBs expressed in tractable DLs, such as DL-Lite, it was shown that the evolution suffers from inexpressibility, i.e., the result of evolution cannot be expressed ...
