Objective
 The false sensorineural loss caused by otosclerosis
 due to stapes fixation is known as the Carhart notch.
 To examine changes in air-bone gap (ABG)
 and bone-conduction (BC) hearing thresholds by
 comparing preoperative postoperative
 audiometry results patients with chronic otitis media
 (COM), investigate effects of air conduction
 (AC) on B...

Bone conduction (BC) hearing relies on sound vibration transmission in the skull bone. Several clinical findings indicate that in the human, the skull vibration of the inner ear dominates the response for BC sound. Two phenomena transform the vibrations of the skull surrounding the inner ear to an excitation of the basilar membrane, (1) inertia of the inner ear fluid and (2) compression and exp...

We empirically test predictability on asset price using stock selection rules based maximum drawdown and its consecutive recovery. In various equity markets, monthly momentum- weekly contrarian-style portfolios constructed from these alternative criteria are superior not only in forecasting directions of prices but also capturing cross-sectional return differentials. periods, the ranked by meas...
