2 unusual facts about cyclic


2',3'-Cyclic-nucleotide 3'-phosphodiesterase

Deletion of the C-terminus of CNP or phosphorylation abolish the catalytic activity of microtubule formation.

Cyclic/collective pitch mixing

Conventional model helicopters use three independent servos to manipulate the swashplate.


Actin remodeling

Cell surface (cortical) actin remodeling is a cyclic process, and each step is responsive to cell signaling, making this a dynamic process.

Aethiopis

We are almost entirely dependent on a summary of the Cyclic epics contained in the Chrestomathy attributed to an unknown "Proclus" (possibly to be identified with the 2nd-century AD grammarian Eutychius Proclus).

Big Bounce

In 2003, Peter Lynds has put forward a new cosmology model in which time is cyclic.

Bulk loaded liquid propellants

In 1981, the Naval Weapons Center tried a 350 round/minute cyclic bipropellant gun, using 90% Nitric Acid and a proprietary hydrocarbon (probably a low molecular weight alkane, like Propane).

Conformal cyclic cosmology

The conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity, advanced by the theoretical physicists Roger Penrose and Vahe Gurzadyan.

Dance improvisation

B-boying features a heavily improvisational style based on cyclic movement patterns.

Endre Boros

In 1986, Boros settled (with T. Szőnyi) a conjecture by Beniamino Segre about the cyclic structure of finite projective planes, and in 1988 provided the best known bound for a question posed by Paul Erdős about blocking sets of Galois planes.

Forskolin

Cyclic AMP acts by activating cAMP-sensitive pathways such as protein kinase A and Epac.

Generic polynomial

Lenstra showed that a cyclic group does not have a generic polynomial if n is divisible by eight, and Smith explicitly constructs such a polynomial in case n is not divisible by eight.

Geraldine Claudette Darden

Her dissertation was completed under the auspices of James Reid, Ph.D., entitled, "On the Direct Sums of Cyclic Groups".

Great White Brotherhood

Gareth Knight describes its members as the "Masters" or "Inner Plane Adepti", who have "gained all the experience, and all the wisdom resulting from experience, necessary for their spiritual evolution in the worlds of form." While some go on to "higher evolution in other spheres", others become teaching Masters who stay behind to help younger initiates in their "cyclic evolution on this planet".

Hilbert's theorem

Hilbert's Theorem 90, an important result on cyclic extensions of fields that leads to Kummer theory

History of the Big Bang theory

Edgar Allan Poe presented a similar cyclic system in his 1848 essay titled Eureka: A Prose Poem; it is obviously not a scientific work, but Poe, while starting from metaphysical principles, tried to explain the universe using contemporary physical and astronomical knowledge.

Iliupersis

For its storyline we are almost entirely dependent on a summary of the Cyclic epics contained in the Chrestomathy written by an unknown "Proclus" (possibly to be identified with the 2nd century CE grammarian Eutychius Proclus).

Interval cycle

Cyclic tonal progressions in the works of Romantic composers such as Gustav Mahler and Richard Wagner form a link with the cyclic pitch successions in the atonal music of Modernists such as Béla Bartók, Alexander Scriabin, Edgard Varèse, and the Second Viennese School (Arnold Schoenberg, Alban Berg, and Anton Webern).

Kolakoski sequence

For example, Stephen Wolfram describes the Kolakoski sequence in connection with the history of cyclic tag systems.

Marl

Upper Cretaceous cyclic sequences in Germany and marl–opal-rich Tortonian-Messinian strata in the Sorbas basin related to multiple sea drawdown have been correlated with Milankovitch orbital forcing.

Ménage problem

However, two Hamiltonian cycles are considered to be equivalent if they connect the same vertices in the same cyclic order regardless of the starting vertex, while in the ménage problem the starting position is considered significant: if, as in Alice's tea party, all the guests shift their positions by one seat, it is considered a different seating arrangement even though it is described by the same cycle.

Multiscale Electrophysiology Format

Data fidelity is ensured by a 32-bit cyclic redundancy check in each compressed data block using the Koopman polynomial (0xEB31D82E), which has a Hamming distance of from 4 to 114 kbits.

Peter Lynds

Lynds in December 2006 put forward a new cosmology model in which time is cyclic and the universe repeats exactly an infinite number of times.

Polycyclic

Polycyclic compound, in organic chemistry, a cyclic compound with more than one hydrocarbon loop or ring structures

Prelog strain

When water is eliminated from cyclic tertiary alcohols by an E1 route, three major products are formed.

Problems in Latin squares

A related question is to estimate the number of transversals in the Cayley tables of cyclic groups of odd order.

Rāhula

Supporting the first account, in the Dhammapada, the pleasure and joy that a man receives in his wife and children is called a "soft fetter" that ties individuals to life and suffering, not just through eventual loss and separation of loved ones but more deeply and subtly may act as ties to cyclic existence (samsara).

Sexagenary cycle

In China, the cyclic year normally changes on the Chinese Lunar New Year.

Tetrapeptide

Tentoxin (cyclo(N-methyl-L-alanyl-L-leucyl-N-methyl-trans-dehydrophenyl-alanyl-glycyl)) is a natural cyclic tetrapeptide produced by phytopathogenic fungi from genus Alternaria.

Wheel of time

Peter Lynds has put forward a cosmology model in which time is cyclic and the universe repeats exactly an infinite number of times.
