In the direct approach, the model includes the cause of cancer, and depending on the state of the modeled cancer cause, the model represents either a malignant or normal tissue cell.
We show that a discrete tight-binding model representing either a random or a quasiperiodic array of bonds can have the entire energy spectrum or a substantial part of it absolutely continuous, populated by extended eigenfunctions only, when atomic sites are coupled to the lattice locally, or non-locally from one side.
The background model is usually a Markov model representing either the relative frequencies of the nucleotides A, C, G, and T (zeroth order); the 16 di-nucleotides (first order) or any word-length of nucleotides (n-th order).
These different models may represent either different biological systems, or the same biological process at different levels of details or under different biological assumptions.
Because we sought general results, we took special care to establish not only the generality of our results for a particular model but also their robustness to changes in model structure, representing either uncertainty about basic biological process or variability in process between systems of interest.
While most of these models focus on representing either forest demographics including age and height structure, or forest biogeochemistry including plant physiology and ecosystem carbon cycling, it is increasingly seen as crucial that forest ecosystem models include equally good representations of both.
However, the difference between the two models was exactly "1" representing either a gain of new clan or a loss of ancestral clan in either of the two branches.
"The models represent the architects' design concepts at this point in time.
Analysts aren't sure whether these business models represent more than a splash.
Electric models represent a fraction of the overall auto market.
