Facebook and Meta Platforms have been criticized for their management of various content on posts, photos and entire groups and profiles. This includes but is not limited to allowing violent content, including content related to war crimes, and not limiting the spread of fake news and COVID-19 misinformation on their platform, as well as allowing incitement of violence against multiple groups.
The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and ...
Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity. Note that the special characteristics of vectors allow for greater resolution example images. The other algorithms are standardized to a resolution of 160x160 and 218x80 pixels respectively.
The nonlinear response to illumination caused by the quenching process in which adding more light causes the image to become less bright generates sub-diffraction limited information about the location of dye molecules, allowing resolution far beyond the diffraction limit provided high illumination intensities are used.
By 1978, the first theoretical ideas had been developed to break the Abbe limit, which called for using a 4Pi microscope as a confocal laser-scanning fluorescence microscope where the light is focused from all sides to a common focus that is used to scan the object by 'point-by-point' excitation combined with 'point-by-point' detection.

Under the image there should be a set of numbers in the form "NNNNxMMMM." This is the size of the image in pixels. If these numbers do not appear, then the image is smaller than the limit you specified for display in the "Files" pane in your preferences. If you did not adjust that limit, the default size is 800x600 pixels.
Given a sufficient number of observation images, and if the set of observations vary in their phase (i.e. if the images of the scene are shifted by a sub-pixel amount), then the phase information can be used to separate the aliased high-frequency content from the true low-frequency content, and the full-resolution image can be accurately ...
The Facebook privacy and copyright hoaxes are a collection of internet hoaxes claiming that posting a status on Facebook constitutes a legal notice protecting one's posts from copyright infringement [1] or providing privacy protection to one's profile information and posted content. The hoax takes the form of a Facebook status that urges others ...
