Mobile phone usage is nearing 90% of the world population. Harmful effects of Electromagnetic (EMG) radiation have been a concern for regulation. Safe Specific Absorption Rate (SAR) as watt/kg is defined for thermal effects, but EMG has non thermal effects as well. EMG can affect genes, neural tissue, endocrine regulation and sperms. Research workers have pointed out the mechanism of EMG radiat...

Dysaesthesiae of the scalp and neurological abnormality after mobile phone use have been reported previously, but the roles of the phone per se or the radiations in causing these findings have been questioned. We report finding a neurological abnormality in a patient after accidental exposure of the left side of the face to mobile phone radiation [code division multiple access (CDMA)] from a do...

Almost all U.S. states have laws limiting drivers' cellphone use. The evidence suggests that all-driver bans on hand-held phone conversations have resulted in long-term reductions in hand-held phone use, and drivers in ban states reported higher rates of hands-free phone use and lower overall phone use compared with drivers in non-ban states. Bans on all phone use by teenage drivers have not be...

AIMS   To assess the effect of mobile phone intervention on glycaemic control in diabetes self-management. METHODS We searched three electronic databases (PubMed, EMBASE and Cochrane Library) using the following terms: diabetes or diabetes mellitus and mobile phone or cellular phone, or text message. We also manually searched reference lists of relevant papers to identify additional studies. ...

This study aimed to investigate whether third generation mobile phone radiation peaks result in event related potentials. Thirty-one healthy females participated. In this single-blind, cross-over design, a 15 minute mobile phone exposure was compared to two 15 minute sham phone conditions, one preceding and one following the exposure condition. Each participant was measured on two separate days...

This paper considers discriminative training of acoustic models for Mandarin large vocabulary continuous speech recognition. Two frame-level information cues were explored and integrated into the minimum phone error (MPE) training. First, the frame-level entropy of Gaussian posterior probabilities obtained from the word lattice of the training utterance was exploited to weight the framelevel st...

In this work, we validate the effectiveness of our recently proposed integrated template matching and statistical modeling approach on four baseline systems with increasing phone recognition accuracies in the range of 73% to 78% for the TIMIT task. The four baselines were generated using the methods of 1) Discriminative Training (DT) of Minimum Phone Error (MPE), 2) MFCC concatenated with ensem...

This paper investigated the relationship between incrementally logged phone logs and self-reported survey data to derive regularity and predictability from mobile phone usage logs. First, we extracted information not from a single value such as location or call logs, but from multivariate contextual logs. Then we considered the changing pattern of the incrementally logged information over time....

In this paper, we propose two confidence measures (CMs) in speech recognition: one based on acoustic likelihood and the other based on phone duration. For a decoded speech frame aligned to an HMM state, the CM based on acoustic likelihood depends on the relative position of its output likelihood value in the probability distribution of likelihood value in that particular state. The CM of whole ...

There are many circumstances in which it is useful or necessary to recognise phones rather than words, but phone recognition is inherently less accurate than word recognition. We describe here a post-recognition method for “translating” an errorful phone string output by a speech recogniser into a string that more closely matches the transcription. The technique owes something to Kohonen’s idea...
