The robots in Asimov's stories, being Asenion robots, are incapable of knowingly violating the Three Laws but, in principle, a robot in science fiction or in the real world could be non-Asenion. "Asenion" is a misspelling of the name Asimov which was made by an editor of the magazine Planet Stories. [24]

Dendrochronological and oxygen–carbon isotopic analysis was conducted on tree rings collected at two different elevations from three different regions in western Anatolia, Turkey. Tree rings were sampled from Anatolian black pines (Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe) of at least 200 years old through an N–S transect covering Bolu-Mengen (north), Kütahya–Simav, and Antalya–Alanya (south) .

Jun 30, 2008 · White spruce ( Picea glauca (Moench) Voss) trees were sampled to investigate the relationship between ring width and δ 13 C as well as between these descriptors and climate. Cross-sections from eight white spruce trees growing in the Hudson Bay Lowlands, subartic Manitoba, with an establishment date prior to 1775 were selected from our archive.
We developed high-resolution intra-annual oxygen isotope chronologies from tree-ring cellulose of eight trees from five sites along the elevation gradient. The analysis period covers the decade 2007–2016 for seven trees and the period 1987–2016 for one tree, respectively.

Aliquots of cellulose were recovered using a computer-controlled robotic micromilling device at a spatial resolution of ~0.5mm. Ring widths of our cottonwood trees were up to 7mm, permitting high-resolution sampling. δ13C, δ18O and δD values were obtained from each of the 410 collected samples resulting in a continuous record from 1944-2006.

The unique features of this system include the passive and active anti-falling mechanisms, which prevent the robot from falling to the ground under either static or dynamic situations, the capability to vertically or spirally climb up a tree trunk, and the flexibility to suit different trunk sizes.

A robotic micromilling device offers many advantages in that it allows for tree-rings to be accurately mapped and sampled and prevents crosscutting of growth bands. The micromill also allows for the sampling of very small and/or highly curvilinear rings that would be difficult or impossible to sample by other techniques.
