Century Dictionary and Cyclopedia
    • n attrition The rubbing of one thing against another; mutual friction: as, the abrasion of coins by attrition.
    • n attrition The act of wearing away by rubbing; the state of being worn down or smoothed by friction; abrasion.
    • n attrition In theology, imperfect contrition or repentance, with real detestation of sin, and a true purpose of amendment, arising from those supernatural motives of faith which are lower than charity, or the true love of God for his own infinite perfections. Such motives are a love of justice for its own sake, the intrinsic shamefulness of sin, the fear of divine punishment, etc. Attrition remits sin only when complemented by the grace conferred through sacramental absolution. See contrition.

In science:

For finite N , sn is reduced due to the presence of loops in the network, which causes the emergence of attrition of the paths.
Self-avoiding walks on scale-free networks
However, the self-avoiding property causes attrition of the paths, in the sense that a large fraction of paths generated in a stochastic manner have to be abandoned because they are overlapping.
Self-avoiding walks on scale-free networks
Here we study long-range properties of SAWs on equilibrium scale-free networks, and discuss the ‘attrition problem’.
Self-avoiding walks on scale-free networks
IV we analyze the length at which non-reversal random walks intersect themselves in these networks (self-intersection length), and in Sec. V we calculate the average attrition length of kinetic growth SAWs, at which they cannot continue without violating the self-avoidance condition.
Self-avoiding walks on scale-free networks
These walks were studied to describe the irreversible growth of linear polymers , and will allow us to consider the ‘attrition length’ for a walk on a given network (see Sec. V).
Self-avoiding walks on scale-free networks
Note that kinetic growth walks are less sensitive to attrition than non-reversal SAWs, since in the former the walker always escapes whenever a way exists.
Self-avoiding walks on scale-free networks
However, the minimum degree k0 affects strongly other properties of SAWs, such as the attrition length studied in the following section.
Self-avoiding walks on scale-free networks

Self-avoiding walks on scale-free networks
Mean attrition length hLi as a function of system size for SF networks with γ = 3 and several values of k0 .
Self-avoiding walks on scale-free networks
The presence of loops in a network is responsible for attrition of the walks.
Self-avoiding walks on scale-free networks
High-degree nodes are visited more probably than low-degree ones, and once visited the former are more effective to block a SAW in later steps (they have more connections), thus reducing the mean self-intersection and attrition lengths.
Self-avoiding walks on scale-free networks
We have calculated self-intersection and attrition lengths by using an approximate probabilistic method, which yields results in good agreement with those derived from numerical simulations.
Self-avoiding walks on scale-free networks
Both, the average selfintersection length and attrition length scale as a power of the system size N .
Self-avoiding walks on scale-free networks
The length of kinetic growth walks in scalefree networks is limited by attrition of the paths, and the mean attrition length follows a dependence hLi ∼ N α , with α depending on γ and the minimum degree k0 .
