A finite metric (or more properly semimetric) on n points is a nonnegative vector d = (dij) 1 i < j n that satisfies the triangle inequality dij dik + djk . The L 1 (or Manhattan ) distance x - y 1 between two vectors x = (xi) and y = (yi) in Rm is given by x - ...
Mathematically a norm is a total size or length of all vectors in a vector space or matrices. For simplicity, we can say that the higher the norm is, the bigger the (value in) matrix or vector is. Norm may come in many forms and many names, including these popular name:Euclidean dis...

A sequence of input signals is distributed through a data pipe line (495) to a programmable accumulator. The accumulator (498) sums the input signals to generate an output signal. The L1 norm operation can be performed using the distance between two vectors....
(B) Detailed interactions between BMAL1 and E-box. The red dashed lines represent the hydro- gen-bonding contacts and the black dashed line represents the distance between two atoms. The bond lengths or distance are shown in Angstroms (Å). (C) ITC measurements of the binding affinities ...

3C), suggesting an association between the molecules. Then, proximity ligation (Duolink) was performed to analyze the possibility that the association was within a distance of 40 nm or less. Positive Duolink amplification signals (red) were detected in many nuclei (Fig. 3D), confirming that...
In plants, inactivation of either of the thylakoid proteins PGR5 and PGRL1 impairs cyclic electron flow (CEF) around photosystem I. Because PGR5 is unstable in the absence of the redox-active PGRL1, but not vice versa, PGRL1 is thought to be essential fo
