What's the difference between cyclide and quartic?
Cyclide
Definition:
(n.) A surface of the fourth degree, having certain special relations to spherical surfaces. The tore or anchor ring is one of the cyclides.
Example Sentences:
(1) Clinically observed were inflammatory changes of the conjunctiva and cyclids margins as well as traumatisation of the corneal and conjunctival epithelia, appearing at different stages on the experiment.
(2) These studies suggest that methylprednisolone may be beneficial in the prevention of myocardial failure following hypoxia via a modulation in myocardial cyclid GMP content.
(3) All endoperoxide analogues tested (bicyclic compounds) were powerful platelet stimulants, and all active compounds (whether mono- or bi-cyclid) apparently acted via the same receptor as the endogenous prostaglandin endoperoxides.
(4) Infection is related to ingestion of "ceviche", a very popular mexican delicacy made with raw Cyclid fishes of the Miguel Aleman dam.
(5) The bilayer configurations in all species were consistent with the two geometries predicted by minimal energy solutions of a continuum theory of liquid crystals subject to the boundary conditions imposed by the amphiphilic nature of lung surfactant lipid: concentric (either closed or partially closed) spheres and Dupin cyclides.
(6) The mechanical and thermal stresses induced by sonication nucleate liquid crystalline defects in the liposomes, including edge and screw dislocations and +1 disclinations, but the Dupin cyclide structure of unsonicated liposomes is still recognizable in the larger particles after sonication.
(7) Assay of phosphodiesterase using 3-H-labeled cyclid AMP of frog and rabbit corneal epithelial homogenates showed an inhibitory effect of ascorbic acid.
(8) Acetylcholine (1muM) increased cyclid GMP content in paced perfused rat hearts within 15 sec., with peak content occurring at 1 min.
Quartic
Definition:
(a.) Of the fourth degree.
(n.) A quantic of the fourth degree. See Quantic.
(n.) A curve or surface whose equation is of the fourth degree in the variables.
Example Sentences:
(1) To calculate NEmkg, dietary intake must be known or estimated, or it can be calculated using a complicated quartic equation.
(2) The patterns comprised linear, quadratic, cubic, and quartic mathematical functions and varied in spatial complexity.
(3) The transformed values of the third and fourth methods are obtained as the numerical solutions of quartic equations.

(7) Post hoc analysis revealed a significant quartic trend for age.
(8) This quartic equation, when solved, gives the percentages of selected feedstuffs necessary to balance a diet.
(9) Since in many models it is necessary to go beyond linear terms, quadratic, cubic and quartic terms are also derived explicitly and details given of their extension to higher degrees.
(10) The polynomial coefficients provided an accurate description of dental arch morphology with the quadratic (chi 2) and quartic (chi 4) terms reflecting arch shape and the linear (chi) and cubic (chi 3) terms summarizing asymmetry.
(11) There were no significant differences between the groups in either the quadratic or quartic terms.

(17) The bile acid pool half-life remained constant until 28 days of age when it increased significantly and then held steady until it increased again at 8 wk of age following a quartic trend.
