BioArt. BioArt is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy, and biotechnology (including technologies such as genetic engineering, tissue culture, and cloning) the artworks are ...
Cell Painting. The Cell Painting assay is a high-content, high-throughput imaging technique used to capture a wide array of cellular phenotypes in response to diverse perturbations. [1] These phenotypes, often termed "morphological profiles", can be used to understand various biological phenomena, including cellular responses to genetic changes ...
Coalescent theory. Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation ...
The left fixed point is always unstable, and the right one stable. Figure 5. Ideal transcritical bifurcation phase portraits. Fixed points are marked on the x-axis, each trajectory in a different color. The direction of the arrows indicates which direction they move as r increases. The red point is unstable, and the blue point is unstable.
Photo-activated localization microscopy ( PALM or FPALM) [1] [2] and stochastic optical reconstruction microscopy (STORM) [3] are widefield (as opposed to point scanning techniques such as laser scanning confocal microscopy) fluorescence microscopy imaging methods that allow obtaining images with a resolution beyond the diffraction limit.
The CO 2 compensation point (Γ) is the CO 2 concentration at which the rate of photosynthesis exactly matches the rate of respiration. There is a significant difference in Γ between C 3 plants and C 4 plants: on land, the typical value for Γ in a C 3 plant ranges from 40–100 μmol/mol, while in C 4 plants the values are lower at 3–10 μmol/mol. Plants with a weaker CCM, such as C2 ...
Pointillism. Pointillism ( / ˈpwæ̃tɪlɪzəm /, also US: / ˈpwɑːn - ˌ ˈpɔɪn -/) [1] is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism.
The pin-point method (or point-intercept method) is used for non-destructive measurements of plant cover and plant biomass. [1] [2] In a pin-point analysis, a frame (or a transect) with a fixed grid pattern is placed above the vegetation. A pin is inserted vertically through one of the grid points into the vegetation and will typically touch a ...
