Compactification on Calabi-Yau threefolds: consistent truncation to pure supergravity
Published 2025-03-01“…We furthermore match the supersymmetry transformations and demonstrate the consistency to full non-linear order in fermions. Our construction is independent of the choice of Calabi-Yau threefold and only involves the universal structures such as the Kähler form and the holomorphic three-form, in agreement with implicit constructions in the generalised geometry literature. …”

Estimating the body size of orchid bees (Hymenoptera: Apidae: Euglossini) using the distance between their tegulae
Published 2024-02-01“…In the past, estimates of body mass were often based on general mathematical equations in which body mass was related to linear measurements of anatomical structures. For example, in female bees, estimates of dry body mass are expected to follow a non-linear relationship (power function) with the distance between the tegulae on their thorax, also known as the intertegular distance (ITD). …”
