Such cell death can be caused by disruptions in the process of either fusion or fission. [4] The shapes of mitochondria in cells are continually changing via a combination of fission, fusion, and motility. Specifically, fusion assists in modifying stress by integrating the contents of slightly damaged mitochondria as a form of complementation.
Mitochondrial fission is the process by which mitochondria divide or segregate into two separate mitochondrial organelles. Mitochondrial fission is counteracted by mitochondrial fusion , where two mitochondria fuse together to form a larger one. [ 1 ]
Melodic fission occurring in mm 1-2 of the Allemande from J.S. Bach's violin partita in B minor (BWV 1002). [1] Red and blue have been used to denote the two separate streams. In music cognition , melodic fission (also known as melodic or auditory streaming , or stream segregation ), is a phenomenon in which one line of pitches (an auditory ...
The first Soviet fusion bomb test, RDS-6s, American codename "Joe 4", demonstrated the first fission/fusion/fission "layercake" design, limited below the megaton range, with less than 20% of the yield coming directly from fusion. It was quickly superseded by the Teller-Ulam design. This was the first aerial drop of a fusion weapon.
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [ 1 ]
In ethology, fission–fusion society is one in which the size and composition of the social group change as time passes and animals move throughout the environment; animals merge into a group (fusion)—e.g. sleeping in one place—or split (fission)—e.g. foraging in small groups during the day. For species that live in fission–fusion ...
Mitochondrial fission 1 protein (FIS1) is a protein that in humans is encoded by the FIS1 gene on chromosome 7. [ 5 ] [ 6 ] [ 7 ] This protein is a component of a mitochondrial complex, the ARCosome, that promotes mitochondrial fission .
Fission (biology), the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original; Nuclear fission, when the nucleus of an atom splits into smaller parts; Fission (band), a Swedish death metal band; Fission, by Jens Johansson
