Field emission is usually analyzed using Fowler–Nord- heim (F–N) theory, according to which emission current density is dependent on the ... significant emission current was observed from sample 1 in the measurement range. This confirmed that the cat- alytic particles lying on the substrate had no contribution and emission occu...

This type of SR phenomenon has potential for improving sensorim- otor ... inhibition by facilitating muscle activation. Thus, greater dynamic ankle joint stability may result from SR stimulation. In our cur- rent study, six weeks of coordination training with SR stimu...
