These poles directly influence how the system responds to inputs and disturbances. Ackermann's formula provides a direct way to calculate the necessary adjustments—specifically, the feedback gains —needed to move the system's poles to the target locations.
Prospective Outlook on Long-term Energy Systems (POLES) is a world simulation model for the energy sector that runs on the Vensim software.It is a techno-economic model with endogenous projection of energy prices, a complete accounting of energy demand and supply of numerous energy vectors and associated technologies, and a carbon dioxide and other greenhouse gases emissions module.
The level of support for evolution among scientists, the public, and other groups is a topic that frequently arises in the creation–evolution controversy, and touches on educational, religious, philosophical, scientific, and political issues.
Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as the latitudinal diversity gradient. [1] The latitudinal diversity gradient is one of the most widely recognized patterns in ecology. [1] It has been observed to varying degrees in Earth's past. [2]
Dennett, Daniel (1995), Darwin's Dangerous Idea (Evolution and the Meaning of Life), Simon & Schuster, ISBN 0-684-82471-X. Dennett's book explores the significance and power of natural selection. He supports Dawkins' views on evolution, and is at times quite critical of Gould's approach. Gould, Stephen Jay (2002). The Structure of Evolutionary ...
The primary driver of evolution is the mutation or changes in genes and accounting for those changes over time determines the approximate genetic distance between species. These specific molecular clocks are fairly conserved across a range of species and have a constant rate of mutation like a clock and are calibrated based on evolutionary ...
The rate of evolution is quantified as the speed of genetic or morphological change in a lineage over a period of time. The speed at which a molecular entity (such as a protein, gene, etc.) evolves is of considerable interest in evolutionary biology since determining the evolutionary rate is the first step in characterizing its evolution .

In this special case, the Hilbert space is a space of irreducible unitary representations of the inhomogeneous Lorentz group (the Poincaré group); the S-matrix is the evolution operator between = (the distant past), and = + (the distant future). It is defined only in the limit of zero energy density (or infinite particle separation distance).
