Multiple Giant Impacts and Chemical Equilibria: An Integrated Approach to Rocky Planet Formation
During the formation of rocky planets, the surface environments of growing protoplanets were dramatically different from those of present-day planets. The release of gravitational energy during accretion would have maintained a molten surface layer, forming a magma ocean. Simultaneously, sufficiently massive protoplanets could acquire hydrogen-rich proto-atmospheres by capturing gas from the protoplanetary disk. Chemical equilibration among the atmosphere, magma ocean, and iron core plays a key…

Möglicherweise Militärdrohne in Polen abgestürzt
Im Osten Polens ist nach Einschätzung der Behörden offenbar eine Militärdrohne in ein Maisfeld gestürzt. In der rund 100 Kilometer südöstlich von Warschau gelegenen Ortschaft Osiny ereignete sich in der Nacht zum Mittwoch eine Explosion, wie die Polizei mitteilte. Opfer gab es demnach nicht, doch in nahe gelegenen Gebäuden wurden Fenster beschädigt. Nach Angaben der Staatsanwal…

Towards stable AI systems for Evaluating Arabic Pronunciations
Modern Arabic ASR systems such as wav2vec 2.0 excel at word- and sentence-level transcription, yet struggle to classify isolated letters. In this study, we show that this phoneme-level task, crucial for language learning, speech therapy, and phonetic research, is challenging because isolated letters lack co-articulatory cues, provide no lexical context, and last only a few hundred milliseconds. Recogniser systems must therefore rely solely on variable acoustic cues, a difficulty heightened by A…

Evaluating the Quality of Open Building Datasets for Mapping Urban Inequality: A Comparative Analysis Across 5 Cities
While informal settlements lack focused development and are highly dynamic, the quality of spatial data for these places may be uncertain. This study evaluates the quality and biases of AI-generated Open Building Datasets (OBDs) generated by Google and Microsoft against OpenStreetMap (OSM) data, across diverse global cities including Accra, Nairobi, Caracas, Berlin, and Houston. The Intersection over Union (IoU), overlap analysis and a positional accuracy algorithm are used to analyse the simil…
