  • The use of ANNs as software sensors in microalgae cultivation has been reported for the estimation of cell counts, contamination in monoalgal cultures, or biomass concentration using fluorescence spectra, multispectral absorption, and reflectance through offline monitoring.

    “The use of ANNs as software sensors in microalgae cultivation has been reported for the estimation of cell counts, contamination in monoalgal cultures, or biomass concentration using fluorescence spectra, multispectral absorption, and reflectance through offline monitoring (López Expósito et al. 2017; Franco et al. 2019; Liu et al. 2020a).”

  • The cell concentration range was 2×10^5 to 6.4×10^6 cells/mL.

    “The cell concentration range was 2 × 10 5 -6.4 × 10 6 cells•mL -1 .”
  • Comparison of measured and predicted cell count values in three validation sets showed an acceptable result only in one set, with errors in range -8 to 34% of true value, while other two sets had prediction errors in range 5 to 110% and -95 to 25% of true value.

    “Comparison of the measured and predicted cell count values in three validation sets showed an acceptable result only in one set, with errors in the range -8 to 34% of the true (hemocytometer measured) value, where the other two sets had prediction errors in the range 5 to 110% and -95 to 25% of the true value.”
  • An ANN or Genetic-Algorithm-ANN was trained to correlate cell count in C. reinhardtii cultivation measured with a hemocytometer with fluorescence emission intensity of suspension samples at 101 wavelengths in 660-760 nm with 1 nm steps, excited with 470 nm LED.

    “An ANN or Genetic-Algorithm-ANN was trained to correlate cell count in a C. reinhardtii cultivation measured with a hemocytometer with the fluorescence emission intensity of suspension samples at 101 wavelengths acquired in the range 660-760 nm with 1 nm steps, excited with a 470 nm LED [39].”
  • With increasing cell concentration, the fluorescence peak moved to a slightly longer wavelength.

    “With increasing cell concentration, the peak moved to a slightly longer wavelength.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
