Asymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents, terrorist groups, or resistance militias operating within territory mostly controlled by the superior force.
Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). [1] Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. [2]
Notably, stem cells divide asymmetrically to give rise to two distinct daughter cells: one copy of the original stem cell as well as a second daughter programmed to differentiate into a non-stem cell fate. (In times of growth or regeneration, stem cells can also divide symmetrically, to produce two identical copies of the original cell.
For example, human male brains are more asymmetrically lateralized than those of females. However, gene expression studies done by Hawrylycz and colleagues and Pletikos and colleagues, were not able to detect asymmetry between the hemispheres on the population level. [3] [4] People with autism have much more symmetrical brains than people ...
E does not c-command any node because it does not have a sister node or any daughter nodes. F c-commands G. G c-commands F. If node A c-commands node B, and B also c-commands A, it can be said that A symmetrically c-commands B. If A c-commands B but B does not c-command A, then A asymmetrically c-commands B.
An example of an asymmetric non-transitive, even antitransitive relation is the rock paper scissors relation: if beats , then does not beat ; and if beats and beats , then does not beat . Restrictions and converses of asymmetric relations are also asymmetric.
Asymmetric federalism or asymmetrical federalism is found in a federation or other types of union in which different constituent states possess different powers: one or more of the substates has considerably more autonomy than the other substates, although they have the same constitutional status.
John- TOP nani-o what- ACC kaimashita bought ka Q John-wa nani-o kaimashita ka John-TOP what-ACC bought Q 'What did John buy' Japanese has an overt "question particle" (ka), which appears at the end of the sentence in questions. It is generally assumed that languages such as English have a "covert" (i.e. phonologically null) equivalent of this particle in the 'C' position of the clause — the ...
