A 'gradual' deceleration has a time from onset to nadir of 30 seconds or more. Early decelerations begin and end at approximately the same time as contractions, and the low point of the fetal heart rate occurs at the peak of the contraction. [7] Late decelerations: a result of placental insufficiency, which can result in fetal distress ...
English: The Early effect: A graph of the collector current (I C) against collector-emitter voltage (V CE). The tangents to the currents at large voltages extrapolate backwards to the same point: the Early voltage (−V A).
Some visual variable can be combined harmoniously to make a map clearer and more informative, while other combinations tend to add more confusion than usefulness. For example, early experiments with using Chernoff faces on maps have been criticized as difficult to interpret correctly. [23]
On fetal heart tracing (a linear recording of the fetal heart rate) this would usually look like moderate to severe variable decelerations. [6] In overt cord prolapse, the cord can be seen or felt on the vulva or vagina. [1] The main issue with cord prolapse is that, once the cord is prolapsed, it is prone to compression by the foetus and the womb.
This is typically the case in sentences like "function of a real variable", "x is the variable of the function f : x ↦ f(x)", "f is a function of the variable x" (meaning that the argument of the function is referred to by the variable x). In the same context, variables that are independent of x define constant functions and are therefore ...
This notion has made it possible to use the methods of graph theory in universal algebra and several other areas of discrete mathematics and computer science.Graph algebras have been used, for example, in constructions concerning dualities, [2] equational theories, [3] flatness, [4] groupoid rings, [5] topologies, [6] varieties, [7] finite-state machines, [8] [9] tree languages and tree ...
An ordered pair of vertices, such as an edge in a directed graph. An arrow (x, y) has a tail x, a head y, and a direction from x to y; y is said to be the direct successor to x and x the direct predecessor to y. The arrow (y, x) is the inverted arrow of the arrow (x, y). articulation point A vertex in a connected graph whose removal would ...
Equivalently, a comparability graph is a graph that has a transitive orientation, [3] an assignment of directions to the edges of the graph (i.e. an orientation of the graph) such that the adjacency relation of the resulting directed graph is transitive: whenever there exist directed edges (x,y) and (y,z), there must exist an edge (x,z).
