The significance of compression wood in restoration of the leader in Pinus sihestris L. damaged by moose (Alces alces). II. Structure of growth rings in regenerating stems in relation to juvenile wood formation

open access: yesActa Societatis Botanicorum Poloniae, 2015
The corewood of pine ds very prone to compression wood formation, this changing the whole pattern of the tree ring structure and the siz.es of early and late wood. Compression wood always increases the formation of late wood at the expense of early wood.

Rings Reconcile Genotypic and Phenotypic Evolution within the Proteobacteria. [PDF]

open access: yes, 2015
Although prokaryotes are usually classified using molecular phylogenies instead of phenotypes after the advent of gene sequencing, neither of these methods is satisfactory because the phenotypes cannot explain the molecular trees and the trees do not fit

Atmospheric iodine (127I and 129I) record in spruce tree rings in the northeast Qinghai-Tibet Plateau.

open access: yesEnvironmental Science and Technology, 2019
Atmospheric iodine isotopes have significant impacts on climate change and human health. However, the sources, transport pathway, and transfer process of atmospheric iodine are still not well understood.

Spurious shear induced by the tree rings of the LSST CCDs

open access: yes, 2015
We present an analysis of the impact of the tree rings seen in the candidate sensors of the Large Synoptic Survey Telescope (LSST) on galaxy-shape measurements. The tree rings are a consequence of transverse electric fields caused by circularly symmetric

Elements content in tree rings from Xi'an, China and environmental variations in the past 30 years [PDF]

open access: yes, 2018
Using inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectroscopy (ICP-AES), the characteristics of chemical elements were analyzed in white poplar (Populus bonatii Levl.) and ailanthus (Ailanthus ...

Analysis of modified degree six chordal rings and traditional chordal rings degree six interconnection network [PDF]

open access: yes, 2008
Chordal rings are attractive network interconnection due to their short diameters especially when the degree was increased. Chordal rings were related to find the shortest path in a ring structured.
