What's the difference between dichromatic and occurring?

Dichromatic


Definition:

  • (a.) Having or exhibiting two colors.
  • (a.) Having two color varieties, or two phases differing in color, independently of age or sex, as in certain birds and insects.

Example Sentences:

  • (4) The results indicate that dichromatic and trichromatic monkeys differ only trivially on tests where performance is based on the contributions of non-opponent mechanisms, that the contribution of spectrally opponent mechanisms to the "brightness signal" is very similar in trichromatic and dichromatic monkeys, and that in increment-threshold discriminations where there are both chromaticity and luminance cues some test wavelengths yield superior performance for trichromats while others appear to favor the dichromat.

  • (6) Spectral characteristics of X-linked Dichromats (13 protanopes, 20 deuteranopes) were studied with spectral ERG.
  • (7) The results imply that newborns have some, albeit limited, ability to discriminate chromatic from achromatic stimuli and hence, that they are at least dichromats.
  • (8) Measurements were carried out using noninvasive techniques: quantitative computer tomography and dual photon absorptiometry (mono- and dichromatic).
  • (9) Many errors were due to the small number of protanopes averaged and inability to distinguish trichromats from dichromats.

  • (13) Thus the color vision in these animals is dichromatic.
  • (14) Spectrophotometric analysis of this blue dye at different concentrations and with or without heparin showed that the reddish hues are due to dichromatism and not metachromasia.
  • (15) The results suggest that the adult expression of dichromatic color vision does not depend on color experience during the first 4 months of life.
  • (16) Collectively, these and previous results imply that although newborns have at least dichromatic color vision, they possess relatively poor chromatic-achromatic discrimination in two spectral regions - in the short-wavelengths (including stimuli of 470-480 nm) and in the mid-wavelengths (including 565 nm).
  • (17) (3)-(8) are consistent and allow the calculation of a maximum optical density for those pigments which underlie the dichromats' long-wave mechanism.
  • (18) An intense background also changes the relative spectral sensitivity of the dichromats.
  • (19) Temporal properties of the short-wavelength cone mechanism of the California ground squirrel (Spermophilus beecheyi), a dichromat, were explored with single light pulses and pulse trains.
  • (20) Sampling was from the femoral artery through a dichromatic cuvette densitometer.

Occurring


Definition:

  • (p. pr. & vb. n.) of Occur

Example Sentences:

  • (2) Direct fetal digitalization led to a reduction in umbilical artery resistance, a decline in the abdominal circumference from 20.3 to 17.8 cm, and resolution of the ascites within 72 h. Despite this dramatic response to therapy, fetal death occurred on day 5 of treatment.
  • (3) Patients with papillary carcinoma with a good cell-mediated immune response occurred with much lower infiltration of the tumor boundary with lymphocyte whereas the follicular carcinoma less cell-mediated immunity was associated with dense lymphocytic infiltration, suggesting the biological relevance of lymphocytic infiltration may be different for the two histologic variants.
  • (4) It is concluded that during exposure to simulated microgravity early signs of osteoporosis occur in the tibial spongiosa and that changes in the spongy matter of tubular bones and vertebrae are similar and systemic.
  • (5) HSV I infection of the hand classically occurs in children with herpetic stomatitis and in health care workers infected during patient care delivery.
