Is mobile phone radiofrequency radiation all bad?
In 1992, Dr. Sheldon Wolff published his widely cited paper ‘Is Radiation All Bad? The Search for Adaptation’ [1]. Dr. Wolff was widely honoured for his findings on the stimulatory effects of low doses of ionising radiation. Now, due to exponential increase in mobile phone use (4.6 billion users globally), we should ask a new question, ‘‘Is mobile phone radiofrequency (RF) radiation all bad?’’ ...

Materials and Methods: In this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...
متن کاملForgetting Exceptions is Harmful
We show that in language learning, contrary to received wisdom, keeping exceptional training instances in memory can be beneecial for generalization accuracy. We investigate this phenomenon empirically on a selection of benchmark natural language processing tasks: grapheme-to-phoneme conversion, part-of-speech tagging, prepositional-phrase attachment, and base noun phrase chunking. In a rst ser...
متن کاملIs Consistency Harmful?
One of the major goals of most early concept learners was to find hypotheses that were perfectly consistent with the training data. It was believed that this goal would indirectly achieve a high degree of predictive accuracy on a set of test data. Later research has partially disproved this belief. However, the issue of consistency has not yet been resolved completely. We examine the issue of c...
