One variety is here recognized, C. javensis var. polyphyllus (including C. acuminatu…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

Up to 50% of all children and adolescents growing up worldwide are exposed to at least one form of childhood adversity (CA), which is one of the strongest predictors for later-life psychopathology.
