The deep submicron (DSM) semiconductor technologies will make the worst-case design impossible, since they can not provide design margins that it requires. Research directions should go to typical-case design methodologies, where designers are focusing on typical cases rather than worrying about very rare worst cases. In this paper, canary logic is proposed(More)
—Negative Bias Temperature Instability (NBTI) is one of the major reliability problems in advanced technologies. NBTI causes threshold voltage degradation in a PMOS transistor which is biased to negative voltage. In an SRAM cell, due to NBTI, threshold voltage degrades in the load PMOS transistors. The degradation has the impact on Static Noise Margin(More)
It is well known that sound presented in the contralateral ear can elicit the activity of the olivocochlear (OC) efferent. In the present study, the effects of the addition of contralateral noise on the psychophysical measurements of auditory thresholds were investigated in human subjects with normal hearing. The results obtained in the present study(More)
<italic>Recently, the practice of speculation in resolving data dependences has been studied as a means of extracting more instruction level parallelism (ILP). An outcome of an instruction is predicted by value predictors. The instruction and its dependent instructions can be executed simultaneously, thereby exploiting ILP aggressively. One of the serious(More)
SUMMARY Operand bypass logic is likely to be one of the critical structures for future microprocessors to achieve high clock speed. The logic delay causes the execution time budget to be reduced significantly, so that the execution stage is divided into several stages. The variable latency pipeline (VLP) structure has the advantages of pipelining and(More)
OBJECTIVE To assess the acoustic transfer function of the Eustachian tube by means of audiometric measurements in order to evaluate the severity of the patulous condition. MATERIAL AND METHODS Detection thresholds for tones presented in the nasal cavity (at the nostril) were measured in subjects with a patulous Eustachian tube (PET) and in normal(More)
OBJECTIVE Nasal-noise masking audiometry was developed to assess the acoustic transfer function from the nasopharyngeal cavity to the middle ear via patulous eustachian tube (ET). STUDY DESIGN Prospective. SETTING Tertiary referral center. PATIENTS Twenty-seven ears of 18 patients with patulous ET and 20 ears of 10 healthy subjects with no history of(More)
CONCLUSION Trans-tympanic insertion of a new silicone plug seems to be useful for controlling the distressing symptoms of patients with a chronic patulous Eustachian tube (PET). OBJECTIVE To evaluate the effectiveness of a new silicone plug for blocking the isthmus of a PET in patients whose symptoms were resistant to other therapies for > 6 months. (More)
