What's the difference between invariant and varying?

Invariant


Definition:

  • (n.) An invariable quantity; specifically, a function of the coefficients of one or more forms, which remains unaltered, when these undergo suitable linear transformations.

Example Sentences:

  • (7) It is suggested that a general manner of folding may be a common feature of the heterogeneous population of kappa-chains: one bridge which folds an invariable stretch of the chain, another bridge which folds a stretch that varies from protein to protein, and a bridge at the C-terminus which is the interchain link.
  • (8) An obsessional artist who was an enemy of all institutions, cinematic as well as social, and whose principal theme was intolerance, he invariably gets delivered to us today by institutions - most recently the National Film Theatre, which starts a Dreyer retrospective this month - that can't always be counted on to represent him in all his complexity.
  • (9) Patients with anti-NC1 antibodies were characterised by linear immune deposits along the glomerular basement membrane and the clinical outcome was invariably grim.

  • (12) The species invariance of this lysine residue, number 175, and the substantial conservation of adjacent sequence support the probability for a functional role in catalysis of the lysyl epsilon-amino group.
  • (13) Under these assumptions, any time-invariant variable may behave like a metabolite concentration, i.e.
  • (14) However, in conical cells the new oral apparatus and fission line form well posterior to the cell equator, so the opisthes are invariably smaller than proters.

  • (16) Limited data indicates that, while enhanced thermal stability invariably results, the optimum temperature for catalysis may not change.
  • (17) The relative invariance of the allometric baselines of wing morphology in nature is most easily explained as the result of continuous natural selection around a local optimum of functional design.
  • (18) When the paper had some explaining to do, Kuttner was invariably asked to carry out that task.
  • (19) We found that NS1 cells express correctly sized mRNA for the MHC class II genes A alpha, E alpha and the invariant chain.
  • (20) When we reached our summit, or whatever spot was deemed by my father to be of adequately punishing distance from the car to deserve lunch, Dad would invariably find he had forgotten his Swiss army knife (looking back, I begin to doubt he ever had one) and instead would cut cheese into slices with the edge of his credit card.

Varying


Definition:

  • (p. pr. & vb. n.) of Vary
  • () a. & n. from Vary.

Example Sentences:

  • (2) Ethanol and L-ethionine induce acute steatosis without necrosis, whereas azaserine, carbon tetrachloride, and D-galactosamine are known to produce steatosis with varying degrees of hepatic necrosis.
  • (3) The time of observation varied between 2 and 17 years.
  • (4) However, the relationships between sociometric status and social perception varied as a function of task.
  • (5) Their contour lengths varied from 0.28 to 51 micron, but unlike in the case of maize, a large difference was not observed in the distribution of molecular classes greater than 1.0 micron between N and S cytoplasms of sugar beet.
  • (6) In four main regions the conservation varied from 83-91% while in the remaining regions the homology dropped to between 56-62%.
  • (7) For related pairs, both the primes (first pictures) and targets (second pictures) varied in rated "typicality" (Rosch, 1975), being either typical or relatively atypical members of their primary superordinate category.
  • (8) Change of steps in achieved just by varying the reaction conditions without any product purification.
  • (9) SD is shown to have therapeutic and differential diagnostic significance in varying pathological conditions of cerebral dopaminergic systems.
  • (10) The relative strength of the progressions varies with excitation wavelength and this, together with the absence of a common origin, indicates the existence of two independent emitting states with 0-0' levels separated by either 300 or 1000 cm-1.
  • (11) Although the relative contributions of different fuels varies greatly in different organisms, in none is there a simple reliance on stored ATP.

  • (13) The standard varies from modest to lavish – choose carefully and you could be staying in an antique-filled room with your host's paintings on the walls, and breakfasting on the veranda of a tropical garden.
