Petunia embryos carrying the no apical meristem (nam) mutation fail to develop a shoot apical meristem. Occasional shoots on nam- seedlings bear flowers that develop ten instead of five primordia in the second whorl. Double mutants with the homeotic gene green petals show that nam acts independently of organ identify in whorl 2 and now also affects primordium number in whorl 3. The nam gene was...

In this paper, we present the use of stethoscope and silicon NAM microphones in automatic speech recognition. NAM microphones are special acoustic sensors, which are attached behind the talker’s ear and can capture not only normal (audible) speech, but also very quietly uttered speech (non-audible murmur). As a result, NAM microphones can be applied in automatic speech recognition systems when ...

We developed the next generation of skin-attachment sensors for sampling NAM (Non-Audible Murmur) signals by using soft silicone, which has an acoustic impedance close to that of human flesh, as the prime medium of vibration. With new NAM microphones we could sample expanded target voice signal, suppressing air conduction noise signal to low by the experiment of synchronous stereo sampling of a...

Non-Audible Murmur (NAM) is an extremely soft whispered voice detected by a special body-conductive microphone called a NAM microphone. Although NAM is a promising medium for silent speech communication, its quality is significantly degraded by its faint volume and spectral changes caused by body-conductive recording. To improve the quality of NAM, several enhancement methods based on statistic...

BACKGROUND We previously reported that serum N1-methylnicotinamide (me-Nam), an indicator of nicotinamide N-methyltransferase activity, is associated with obesity and diabetes mellitus in Chinese patients. However, whether nicotinamide N-methyltransferase plays a role in human coronary artery disease (CAD) remains to be elucidated. We aim to investigate the associations of serum me-Nam with CAD...

Keeping order in the classroom, modifying students’ behavioral problems, and implementing regulations codified at schools are among the issues in education involving the minds of headmasters and teachers. Following adolescence appropriate behavioral patterns plays a key role in bringing about the adolescents’ positive social behavior. This study aimed to investigate the predictors o...

The number of households and businesses using HFC cable networks for Internet access is rapidly approaching 40 million in the United States. The cable industry has standardized on a single MAC and physical layer standard, the Data Over Cable System Interface Specification (DOCSIS). The emerging IEEE 802.16 broadband wireless access MAC protocol is based on DOCSIS. We have implemented a simulati...
