What's the difference between concave and inflection?

Concave


Definition:

  • (a.) Hollow and curved or rounded; vaulted; -- said of the interior of a curved surface or line, as of the curve of the of the inner surface of an eggshell, in opposition to convex; as, a concave mirror; the concave arch of the sky.
  • (a.) Hollow; void of contents.
  • (n.) A hollow; an arched vault; a cavity; a recess.
  • (n.) A curved sheath or breasting for a revolving cylinder or roll.
  • (v. t.) To make hollow or concave.

Inflection


Definition:

  • (n.) The act of inflecting, or the state of being inflected.
  • (n.) A bend; a fold; a curve; a turn; a twist.
  • (n.) A slide, modulation, or accent of the voice; as, the rising and the falling inflection.
  • (n.) The variation or change which words undergo to mark case, gender, number, comparison, tense, person, mood, voice, etc.
  • (n.) Any change or modification in the pitch or tone of the voice.
  • (n.) A departure from the monotone, or reciting note, in chanting.
  • (n.) Same as Diffraction.

Example Sentences:

  • (1) An initial complex-soma inflection was observed on the rising phase of the action potential of some cells.
  • (2) When she speaks, it is in a quiet, clear voice that is middle-class but also flat and London-inflected enough to seem almost classless: it is the voice of the modern southern English professional.
  • (3) We conclude from these six studies that: (a) BN presents a counter-example to the claim that non-fluent patients have particular difficulty with those aspects of morphology which have a syntactic function; (b) BN processes both derived and inflected words by mapping the sensory input onto the entire full-form of a complex word, but the semantic and syntactic content of the stem alone is accessed and integrated into the context.
  • (4) The Hill plots of all resonances of the imidazole rings, including the 15N resonances, show a small inflection in the pH range 5.8-6.4.
  • (5) Two of the three inflection points occurring in the voltammograms are invariant with changes in scan rate, pH, CO2, O2, and glucose.
  • (6) With prose that takes the English language and infuses it with inflections and a history that is uniquely Igbo, discernibly Nigerian and unmistakably African, Achebe's is a realism that ensures the enduring relevance of his fiction.
  • (7) We measured the pressure-volume curves (PV curves) of the lung simultaneously at three levels in the esophagus below the tracheal bifurcation using the three-short-balloon-catheter system in 11 normal seated men and compared the inflection points (IP's) of three PV curves with the closing volume (CV) on the single-breath nitrogen washout curve.
  • (8) Stimulation of secretion of preloaded 125I-mannose-N-acetyl-poly-D-lysine by mannose-BSA was more pronounced at lower temperatures with a sharp inflection point at 10 degrees C.

  • (17) On the other hand, the number of groups corresponding to the second inflection is slightly increased.
  • (18) Parameter estimates are obtained from estimates of the size and time at the point of inflection, the size and time at any other arbitrarily selected point, and the maximum size.
