Here, we propose a spatial allocation procedure that builds on the assumption that land transitions occur in two phases: change occurrence and change spreading (or contagion).
We performed a sensitivity analysis where we show that the relation between both rates (i.e. change occurrence and change spreading) allows patches-of-change expand before other patches arise or vice versa.
The period of the occurrence and change of these phenomena can be directly and accurately described by the time scale rather than the real line.
On the other hand, the occurrence and change of many natural phenomena may directly depend on time scales, but not depend on the real line.
Metabolomics studies the occurrence and change of concentrations of small molecular weight chemical compounds (metabolites) in organisms, organs, tissues, cells and ultimately cell compartments in the context of environmental changes, disease or other boundary conditions.
While doing this, students are able to establish a link between the occurrences and changes taking place at the microscopic level and its effect on the macroscopically observable physical quantities.
After every trial, photic sneezers were asked three questions about their subjective experience of sneezing (occurrence, frequency and changes of the "tickling" sensation).
For each day, all early VLF events (early/fast, early/slow, step-like, unusually long recovery events) were visually inspected for the period November 2006 to January 2007, and a count of perturbation events (≥0.2 dB) along with their time of occurrence and amplitude changes (Δ A) in dB was made.
The data reveal a strong temporal correlation between the Ca2+ peak occurrence and morphological changes of neurite retraction and cell body shrinkage.
The occurrence and expression changes of ERFs, PIL5, and GA2 oxidase antisense transcripts were validated by qPCR (Additional file 5: Figure S3).
