Two cast Mg–Al–Ba–Ca alloys, DieMag633 and DieMag844, are the focus of this study. Their microstructureMicrostructure consists of a eutectic Ca-rich structure, the lamellar Al2Ca, and of a hard, compact and brittle interdendritic Ba-rich phase, the Mg21Al3Ba2 phase. Both phases have a much higher hardness than the α-Mg matrix and strongly influence the crack propagationCrack propagation under quas

Low-dimensional topological states have transformed our understanding of charge transportation through quantum materials. Many relevant observations have been connected to bismuth (Bi) containing materials or ultrathin Bi films. Here, we studied sub-monolayer amounts of Bi deposition on the In-terminated InSb(111)A surface using various complementary surface science techniques. Bi deposition at el
Three new genera in the lichen family Teloschistaceae, i.e.: Josefhafellia for the former Caloplaca bellemerei group, Bagliettoella for the former Gyalolechia marmorata branch and Tsarenkoella for the former Caloplaca obscurella group are described and compared with closely related genera. The positions of the species Lacrima apostatica (basionym: Loekoesia apostatica) and Neoplaca sideritis (basi
The distribution of betony (Betonica officinalis L.) is mapped using 390 herbarium specimens from 31 countries (28 European, 2 African and 1 Asian), representing ca 200 localities. Populations from 19 of these localities were used in seed cultivation experiments. Characters that correlate with their biogeography were searched for both in the herbarium material and in the cultivated material. Three
Extracellular vesicles (EVs) have been identified as important mediators of cancer metastasis, especially in the establishment of organ-specific metastatic niches. These membranous vesicles secreted by tumor cells release diverse bioactive cargo, including proteins, nucleic acids, and lipids, thereby allowing for intercellular communication and microenvironment modulation. Recent evidence demonstr
OBJECTIVE: Sarcopenia (loss of muscle strength/mass) reduces physical performance (walking, strength, mobility) and is common in Parkinson's disease (PD), but data on newly diagnosed, untreated patients ("de novo") are scarce. Fatigue is frequent in PD and linked to physical decline and malnutrition, key sarcopenia risk factors. We aimed to describe sarcopenia prevalence, malnutrition risk, and fa
AC-DC converters, which transform alternating current (AC) into controlled direct current (DC), are key instruments for systems requiring stable and efficient power conversion. Among various AC-DC topologies, the Cuk converter topology is increasingly used for power factor correction (PFC) applications, enabling efficient power conversion for various industrial and household devices. Despite its g
Since 2016, the city of Stockholm has been replacing one of the region’s most important communication hubs, the so-called Slussen (The Lock). This enormous building site is situated within the historical city area of Stockholm. For this reason, archaeologists have been involved throughout the process, mapping a giant historic topographic jigsaw puzzle.
