The aim of this study was to investigate the changes in serum pituitary hormone levels and the mechanism of hyponatremia in aneurysmal subarachnoid hemorrhage (SAH). Nuclear medical tests and serum electrolyte monitoring were performed in 49 aneurysmal SAH cases and 10 healthy volunteers. The levels of serum pituitary hormones were significantly higher in(More)
This paper proposes a new algorithm for dense optical flow computation. It combines Gabor filter texture description in a variational framework. The textural features with spatial Gabor filter group are used as an extension to the original bright constant model. The corresponding global energy functional is established, and the flow field at each pixel of(More)
The single robot joint, which contains a DC torque motor and a harmonic reducer, was designed. And sliding mode control strategy by the self-adaptive adjustment of the sliding parameter ε was proposed in this paper. This control strategy can adaptively adjust ε by switching variables and their derivatives according to the system. It is applied(More)
