a 1-cell : is represented by a vertical segment—called a string—separating the plane in two (the right part corresponding to A and the left one to B), a 2-cell α : f ⇒ g : A → B {\displaystyle \alpha :f\Rightarrow g:A\to B} is represented by an intersection of strings (the strings corresponding to f above the link, the strings ...
Interactions in the Standard Model. All Feynman diagrams in the model are built from combinations of these vertices. q is any quark, g is a gluon, X is any charged particle, γ is a photon, f is any fermion, m is any particle with mass (with the possible exception of the neutrinos), m B is any boson with mass. In diagrams with multiple particle ...
A central-peak crater is the most basic form of complex crater. A central-peak crater can have a tightly spaced, ring-like arrangement of peaks, thus be a peak ring crater, though the peak is often single. [3] Central-peak craters can occur in impact craters via meteorites. An Earthly example is Mistastin crater, in Canada. [1]
English: How crater-depth is measured, using the side-view of a typical crater. Depth "A" measures from the surface to the bottom of the crater. Depth "B" measures from the mean height of the rim to the bottom of the crater.

Additionally, crater depth and the volume of melt produced in the impact are directly related to the gravitational acceleration between the two bodies. [4] It has been proposed that “reverse faulting and thrusting at the final crater rim [is] one of the main contributing factors [to] forming the elevated crater rim”. [2]
A property graph, labeled property graph, or attributed graph is a data model of various graph-oriented databases, [1] where pairs of entities are associated by directed relationships, and entities and relationships can have properties.
An explosion crater is a type of crater formed when material is ejected from the surface of the ground by an explosion at or immediately above or below the surface. Stylised cross-section of a crater formed by a below-ground explosion. A crater is formed by an explosion through the displacement and ejection of material from the ground.
