On the Diameter of Tree Associahedra [PDF]
We consider a natural notion of search trees on graphs, which we show is ubiquitous in various areas of discrete mathematics and computer science. Search trees on graphs can be modified by local operations called rotations, which generalize rotations in binary search trees. The rotation graph of search trees on a graph $G$ is the skeleton of a polytope

Diameter-Dependent Semiconducting Carbon Nanotube Network Transistor Performance
Single-walled carbon nanotube (SWCNT) network based devices show application potentials due to their extraordinary electric and optical properties, and the device performance is largely determined by the network morphology and tube–tube junction ...

On the Circuit Diameter Conjecture [PDF]
From the point of view of optimization, a critical issue is relating the combinatorial diameter of a polyhedron to its number of facets $f$ and dimension $d$. In the seminal paper of Klee and Walkup [KW67], the Hirsch conjecture of an upper bound of $f-d$ was shown to be equivalent to several seemingly simpler statements, and was disproved for ...

Amount of carbon sequestration distribution associated with oak tree’s (Quercus castaneifolia C.A. May) bole in relation to physiographical units of Hyrcanian natural forests of Iran [PDF]
Carbon sequestration rate of forest trees and their spatial pattern are prominent factors which affect global carbon dynamic and can be basically applied to predict climate change.
