A hydraulic engine mount (HEM) is an advanced tuned mass damper (TMD) system used to isolate the noise and vibration from chassis. This paper aims design a semiactive HEM based on TMD model, which only tunes damping without affecting other lumped parameters of system. Firstly, dynamic equations modeled as are derived linear parameter model (LPM). Each analyzed identify relevant that affect damp...

We report a case of large vestibular aqueduct syndrome with a markedly dilated endolymphatic sac bilaterally. The density and signal intensity of the extraosseous portion of the sac were higher than those of cerebrospinal fluid on CT and MR studies. The findings may represent protein-rich and hyperosmolar fluid within the endolymphatic sac.

We present a rare case of venous hemangioma in the temporalis muscle that repeatedly and spontaneously enlarged and disappeared over several months. MR imaging depicted multiple fluid-fluid levels in the tumor alongside characteristic findings of hemangioma, indicating that the peculiar course was due to hemorrhage and blood resorption within the tumor.

Quantum states extended over a large volume in phase space have oscillations from quantum interferences in their Wigner distribution on scales smaller than variant Planck's over 2pi [W. H. Zurek, Nature (London) 412, 712 (2001)]]. We investigate the influence of those sub-Planck-scale structures on the sensitivity to an external perturbation of the state's time evolution. While we do find an ac...

PURPOSE The aim of the present study was to investigate the relation between magnetic resonance (MR) evidence of joint effusion and concentrations of proinflammatory cytokines, including interleukin (IL)-1β and IL-6, in washed-out synovial fluid samples obtained from patients with mandibular condyle fractures. PATIENTS AND METHODS Twenty-five joints in 23 patients with mandibular condyle frac...
