On sparse multimode zero forcing transceivers

2015 IEEE International Conference on Digital Signal Processing (DSP), 2015
This paper introduces sparse multimode zero forcing transceivers in which a combination of l 1 -norm minimization and the Farrow structure allows efficient low-cost channel equalization. Specifically, the Farrow structure (i) realizes multimode pulse shaping filters, and (ii) equalizes the amplitude distortion. The phase distortion is equalized using a

Gravity as a zero-point-fluctuation force

Physical Review A, 1989
Sakharov has proposed a suggestive model in which gravity is not a separately existing fundamental force, but rather an induced effect associated with zero-point fluctuations (ZPF's) of the vacuum, in much the same manner as the van der Waals and Casimir forces.

Failed zero forcing

Given a graph G, a set S ⊆ V (G) is called a zero forcing set if repeatedly applying the following colour change rule results in all vertices of G being coloured black: if a black vertex v has exactly one white neighbour u, then u becomes black. The zero forcing number Z(G) is the size of the smallest zero forcing set of G.

On Zero Forcing Number of Permutation Graphs

2012
Zero forcing number, Z(G), of a graph G is the minimum cardinality of a set S of black vertices (whereas vertices in \(V(G)\!\setminus\!S\) are colored white) such that V(G) is turned black after finitely many applications of “the color-change rule”: a white vertex is converted black if it is the only white neighbor of a black vertex.
