Why? Physics and physical dimensions.
In the past 30 years, these models have evolved from rather crude representations of the physics and chemistry impacting trace species to their current state: comprehensive, but not complete.
An overview of this nature should establish which genus, or set, is at issue, that is to say whether we are faced with a theoretical discipline, such as physics (and then with what species, or sub-set, e.g., zoology), or with a non-theoretical discipline such as poetics.
The same is true in biology about the classification of species [13, 14], or in physics the data model underlying the grand unification of forces [15].
Simulation of fsPAGE was performed on COMSOL Multiphysics v4.2a (COMSOL, Inc., Palo Alto, CA) with Transport of Diluted Species and Electric Currents 3D physics modules.
It has to be considered that analogous to the uncertainty principle in quantum physics, present technology in proteomics may influence the protein species composition.
This encompasses all human endeavors, and is vitally dependent upon interstellar propulsion physics to realize our coming of age as an interstellar species.
H2SO4 vapor is a key species in the global-scale sulfur cycle and the physics and chemistry of H2SO4-H2O clouds (Imamura and Hashimoto, 1998, 2001).
In a particle physics analogy, it describes the Brownian motion of individuals within a larger species group.
A concern with modeling and forecasting is the growing awareness that the abundance and, in particular, the toxicity of HAB species may not be explainable solely in terms of the physics and chemistry of the environment.
