TL;DR: Measurements of RFV were successfully obtainable, reproducible, and not influenced by pharmacological pupil dilation, and adjustment to the LSFG technique is required to address apparent issues with RFV, especially saturation effects with higher arterial flow rates.

A novel measure to characterise optimality of diameter relationships at retinal vascular bifurcations
TL;DR: It is proposed that a measure of the extent of departure of optimality ratio from its optimal value of 2−1/3 may be a useful indicator of microvascular endothelial dysfunction in vivo.

Murray's law, the ‘Yarrum’ optimum, and the hydraulic architecture of compound leaves
Katherine A. McCulloh,John S. Sperry,Frederick C. Meinzer,Barbara Lachenbruch,Cristian Atala +4 more
TL;DR: Competence with both optima within the xylem of compound leaves, where conduits should have a minimal mechanical role, is evaluated, indicating that taper is optimized for a constrained conduit number.

Network analysis of an arterial tree
Mair Zamir,S. Phipps +1 more
TL;DR: It is shown that if the tree is to be measured accurately, the concept of 'whole vessels' on which the classical model is based must be abandoned since such vessels do not actually exist in the network, nor can they be accurately defined.

Fluid flows shaping organism morphology
TL;DR: Cytoplasmic fluid flows flowing through the tubular networks have been identified as the key driver of morphological dynamics and inquiries how fluid flows can shape living matter from small to large scales opens up many new avenues for research.
