A systems model of spinal neuro-musculo-skeletal system (alpha - gamma model) is developed to investigate the plausible roles of spinal proprioceptive feedback in movement control. The model is composed of a joint, a pair of antagonist muscles, length and velocity feedback from muscle spindle, as well as spinal stretch reflex, reciprocal inhibition and(More)
The effects of chilling (CT, day/night temperatures of 12/10 °C, an irradiance of 250 μmol m−2 s−1), chilling combined with a low irradiance (CL, 12/10 °C, 80 μmol m−2 s−1), and a high temperature (HT, 42/40 °C, 250 μmol m−2 s−1) on chlorophyll content, chlorophyll fluorescence, and gas exchange were studied in two watermelon cultivars, ZJ8424 and YS01,(More)
Slowing down or even stopping light is the first task to realising optical information transmission and storage. Theoretical studies have revealed that metamaterials can slow down or even stop light; however, the difficulty of preparing metamaterials that operate in visible light hinders progress in the research of slowing or stopping light.
