We assessed the agreement between sampling windows of different size and orientation on packing density estimates in images of the parafoveal cone mosaic acquired using a flood-illumination adaptive optics retinal camera. Horizontal and vertical oriented sampling windows of different size (320x160 µm, 160x80 µm and 80x40 µm) were selected in two retinal locations along the horizontal meridian i...

HIGHLIGHTS AxonPacking: Open-source software for simulating white matter microstructure.Validation on a theoretical disk packing problem.Reproducible and stable for various densities and diameter distributions.Can be used to study interplay between myelin/fiber density and restricted fraction. Quantitative Magnetic Resonance Imaging (MRI) can provide parameters that describe white matter micros...

In the circle packing problem for triangular containers, one asks whether a given set of circles can be packed into a given triangle. Packing problems like this have been shown to be NP-hard. In this paper, we present a new sufficient condition for packing circles into any right or obtuse triangle using only the circles’ combined area: It is possible to pack any circle instance whose combined a...
