Computer science A new class of low-density parity-check matrices with large girth and their applications in networks UNIVERSITY OF LOUISIANA AT LAFAYETTE Gui-Liang Feng ShenJiachenLow-density parity-check codes had been buried in dust for more than thirty years since 1961 when they were invented...
2[uncountableU]COMPUTING a system for finding mistakes when information is sent from one computer or another Parity is used in many hardware applications where detecting an error is helpful. 3[uncountableU]FINANCE when one unit of a currency or COMMODITY (=oil, metal, farm product etc) is wor...
(computer science) The use of a self-checking code in a computer employing binary digits in which the total number of 1's or 0's in each permissible code expression is always even or always odd. (mathematics) Two integers have the same parity if they are both even or both odd. ...
Noun1.parity bit- (computer science) a bit that is used in an error detection procedure in which a 0 or 1 is added to each group of bits so that it will have either an odd number of 1's or an even number of 1's; e.g., if the parity is odd then any group of bits that ...
1]T=x[PTIn−k]=xHT=0,H=[PTIn−k](n−k)xn The H-matrix in (2.52) is known as the parity-check matrix. We can easily verify that (2.53)GHT=[IkP][PIn−k]=P+P=0, meaning that the parity check matrix of an (n,k) LBC H is a matrix of rank n−k and dimensions...

However, despite the nonconservative nature of neurons due to energy exchange between intra‐ and extra‐cellular regions through ion channels, the critical role of non‐Hermitian physics in the photonic analogy of a neuron has been neglected. Here, a neuromorphic non‐Hermitian photonic system ...
