In the present study we attempt to induce a quadruped r obot to walk dynamically on irregular terrain and run on at terrain by using a nervous system model. For dynamic walking on irregular terrain, we employ a control system involving a neural oscillator network, a stretch re BLOCKINex and a exor re BLOCKINex. Stable dynamic walking when obstructions to(More)
The carotid artery (CA) dural ring is an important structure in aneurysm surgery of the paraclinoid region. The authors used three-dimensional computerized tomography (3D-CT) angiography to study the CA dural ring. Three-dimensional computerized tomography angiography was performed in patients with cerebral aneurysms and other cerebrovascular diseases. The(More)
Cerebral angiography (CAG) and transcranial Doppler (TCD) were performed at the same time in 18 patients with ruptured aneurysms within 1-3 days after onset, and the results were compared. Delayed ischemic neurological deficits (DIND) accompanying vascular spasm were detected in 8 patients, but three of the 8 patients recovered from the DIND within about 2(More)
