A leaf of an unrooted tree is a node of vertex degree 1. Note that for a rooted or planted tree, the root vertex is generally not considered a leaf node, whereas all other nodes of degree 1 are. A function to return the leaves of a tree may be implemente
Graph theoryGraphs (Charts)Trees (Mathematics)BoundariesConnectorsTheoremprovingTheoremsLet G be a connected (multi)graph. The leaf exchange spanning tree graph (T subl) (G) of G, with vertex and edge sets is defined. (T sub l) (G) is a spanning subgraph of the so-called spanning tree ...
LeafVein is a graph theory plug-in for Grasshopper. You can generate graphs from geometric objects or maps and perform multiple graph algorithms.
We study the leaf-to-leaf distances on one-dimensionally ordered, full and complete m-ary tree graphs using a recursive approach. In our formulation, unlike in traditional graph theory approaches, leaves are ordered along a line emulating a one-dimensional lattice. We find explicit analytical form...
To improve our understanding of the origin and evolution of mycoheterotrophic plants, we here present the chromosome-scale genome assemblies of two sibling orchid species: partially mycoheterotrophic Platanthera zijinensis and holomycoheterotrophic Platanthera guangdongensis. Comparative analysis shows that myc...
One of the most intriguing questions in evolutionary developmental biology is how an insect acquires a mimicry pattern within its body parts. A striking example of pattern mimicry is found in the pattern diversity of moth and butterfly wings, which is th
LGL syntax examples.This figure shows some examples of graph structures defined through the Leaf Graph Language (LGL). Tree structures of any depth and degree can be encoded using the fork arrow (<) and void node (.) mechanisms. Note that through LGL it is possible to define graphs that ...
Below you'll find an explanation of Digital Phantom Leaf Photography and some of the present state of the art pictures. Cottonwood Tree Leaf In order to help explain how Digital Phantom Leaf Photography is done this image shows how the process begins. A freashly picked cottonwood tree leaf has...
We confirmed that OLE, containing a quantity of oleuropein of 87 % of the total extract, shows anti-proliferative and pro-apoptotic activity on MDA-MB-231 cells. For the first time, our results indicate that OLE inhibits OVCAR-3 cell viability inducing cell cycle arrest, and it also increase...
