There is one other significant difference in the energy loss of fast electrons as compared with that of heavy charged particles.
The reduction of ripple loss of fast ions was clearly demonstrated by both experiments and calculations.
Rather, we propose that the decrease in conductivity is due to loss of fast segmental motions associated with chain ends, which become tethered to the network upon crosslinking.
In this paper, we demonstrate the versatility of NMR relaxometry by presenting three different approaches for obtaining viscosity correlations that incorporate T1, T2, and hydrogen-index (HI) data as a function of temperature and five inter-echo spacings (TE) to account for the signal loss of fast-relaxing components in heavy oil.
This was based on a large body of literature showing that in aging there is a preferential loss of fast motor units (especially in non-postural muscles) resulting in a preferentially loss of fast-twitch myofibers [53], [54].
The reduced peripheral fatiguability of ageing muscle may be due to the loss of fast-twitch muscle fibres and their replacement by slow-twitch muscle fibres which are more resistant to fatigue [20] [21].
Compared with the age-matched wild type mouse, the ageing KO mouse shows greater loss of fast muscle force generation and male muscle mass, good maintenance of grip strength, and increased oxidative metabolism and greater force recovery after fatigue [31].
Fast-fatiguable (FF) motor axons are affected very early (first detectable in nearly 40-day-old SOD1G93A mice), whereas weakening, followed by loss of fast fatigue-resistant (FR) axons and weakening of slow (S) axons coincide with the onset of the clinical phase and progression during advanced clinical stages of the disease, respectively [16].
In particular, mutagenesis of Glu-194 or Glu-204 in bR results in loss of fast proton release [ 3, 4].
These findings indicate that there is a loss of fast-twitch muscle fibres in EDL of hFUS mice (Fig. 9g, h).
