The acoustic properties of a wall jet over a hard-walled backward-facing step of aspect ratios 6, 3, 2, and 1.5 are studied using a 24-channel microphone phased array at Mach numbers up to M=0.6. The Reynolds number based on inflow velocity and step

Objective: Spinal cavernomas (SC) depict a rare entity in spinal lesions, but causal surgical treatment and definite cure is reachable. Operative strategies are very demanding due to the vulnerability of the spinal cord with possibly permanent neurol

Objective: Spinal cord cavernous malformations (CM) are rare, they account for 5–12% of all spinal vascular tumors. The annual bleeding rate is reported to reach 4.5% assuming lesion presence since birth, and an annual re-bleeding rate of 66% per y

Objective: Prediction of outcome after surgery in patients with cervical spondylotic myelopathy remains difficult. Recent studies suggested a correlation between the extent of signal changes on the preoperative MRI and the clinical outcome but a mean
