Self‐supervised Learning of Fine‐to‐Coarse Cuboid Shape Abstraction
Computer Graphics Forum, EarlyView.Abstract The abstraction of 3D objects with simple geometric primitives like cuboids allows us to infer structural information from complex geometry. It is important for 3D shape understanding, structural analysis and geometric modeling. We introduce a novel fine‐to‐coarse self‐supervised learning approach to abstract collections of 3D shapes.

How iteration frequencies affect project uncertainty and risk ‐ An empirically elaborated model
Decision Sciences, EarlyView.Abstract Iterative approaches have gained prominence in new product development (NPD) projects in response to increasingly dynamic and turbulent business environments. In this article, we study how iteration frequency—that is, the rhythm at which development teams revisit and test comprehensive products—affects an NPD project's uncertainty and risk. We

Small-scale dipolarization fronts in the Earth′s magnetotail
Earth and Planetary Physics, 2019 Previous studies suggest that dipolarization fronts (DFs) are 1 to 3RE (RE is the earth radius) wide in the dawn-dusk direction. Recent kinetic simulations have found that DFs may break up into small-scale structures after they are produced by ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, EarlyView.Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
