The possibility of reverter can only follow a fee simple determinable. Example: "O grants Blackacre to A as long as A refrains from drinking alcohol." Analysis: If A never drinks after the grant (and never sells the property), then Blackacre will belong to A at O's death, and be distributed according to the rules of probate .
An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. [1] This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of excitable cells, which include animal cells like neurons and muscle cells, as well as some plant cells.
An attempt to create such an interest is construed as a fee simple subject to condition subsequent (see below), and a person who would have possibility of reverter at common law will instead have a right of entry. [1] A fee simple determinable does not violate the rule against perpetuities, since a possibility of reverter is not subject to the ...
A reversion in property law is a future interest that is retained by the grantor after the conveyance of an estate of a lesser quantum than he has (such as the owner of a fee simple granting a life estate or a leasehold estate).
We can consider as an example a positively charged ion, such as K +, and a negatively charged membrane, as it is commonly the case in most organisms. [4] [5] The membrane voltage opposes the flow of the potassium ions out of the cell and the ions can leave the interior of the cell only if they have sufficient thermal energy to overcome the energy barrier produced by the negative membrane ...
Afterhyperpolarization, or AHP, is the hyperpolarizing phase of a neuron's action potential where the cell's membrane potential falls below the normal resting potential. This is also commonly referred to as an action potential's undershoot phase. AHPs have been segregated into "fast", "medium", and "slow" components that appear to have distinct ...
Figure FHN: To mimick the action potential, the FitzHugh–Nagumo model and its relatives use a function g(V) with negative differential resistance (a negative slope on the I vs. V plot). For comparison, a normal resistor would have a positive slope, by Ohm's law I = GV, where the conductance G is the inverse of resistance G=1/R.
Another kind of acceptable reversion is an incidental one. A Wikipedia editor is not expected to investigate the history of an article to find out if an edit being considered is a reversion of some prior edit. The rule against reversions applies only to cases where the reverter is aware that the edit is a reversion of another edit.
