Rare jongens, die elektronen
Hoe supergeleiding werkt is voor onderzoekers allang geen geheim meer. De laatste vijf jaar hebben ze vooral aandacht voor het onverklaarbare gedrag van de elektronen die in het binnenste van supergeleiders zitten. Een internationaal onderzoeksteam met onder meer Leidse natuurkundigen zette in juli…

Improving vegetation representation in Multi-sensor Earth Observation Products through phenology and trait-based priors
What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

Rare jongens, die Romeinen
Waren jongeren in de Oudheid vroeg-volwassenen met verantwoordelijke publieke functies, of wispelturige, soms idealistische adolescenten? In het boek Jeugd in het Romeinse Rijk analyseren Leids historicus Johan Strubbe en zijn Leuvense collega Christian Laes een debat. Spreken literaire bronnen en inscripties…

Zeldzame aardmetalen voor kwantumopslag
Zeldzame aardmetalen, Rare-earth materialen, zijn goede kandidaten om kwantuminformatie op te slaan, omdat de ongewenste interactie met hun omgeving minimaal is. Aan de andere kant zorgt dit gebrek aan interactie voor een erg lage respons op licht, waardoor data lezen en wegschrijven moeilijk wordt.…
