Recent progress has revealed that the capture of genetic resources of complex microbial communities in metagenome libraries allows the discovery of a richness of new enzymatic diversity that had not previously been imagined. Activity-based screening of such libraries has demonstrated that this new diversity is not simply variations on known sequence themes, but rather the existence of entirely ...

Both musically trained and untrained adults can reproduce the tempo of familiar music with high precision. However, conflicting evidence exists as to how well representations of tempo are preserved within musical imagery. The present study investigated whether previous conflicting evidence might result from the use of different tasks to measure imagined tempo. Tempo judgments for familiar music...

In this article, I scrutinize the process by which scientific research on human subjects is regulated by Institutional Review Boards (IRBs). At the outset, let us agree that at least some biomedical scientific research on human subjects must be externally monitored and that whether government should sometimes be involved in that process is at least an open question. We simply cannot forget the ...

Our goal is to collect a speech corpus for the purpose of studying intelligibility and acoustic differences between the conversational and clear speech styles. The ideal corpus has the following properties: (1) speech has been produced spontaneously as part of a communicative interaction, as opposed to having been read to an imagined interlocutor; (2) entire identical utterances, or large parts...

The use of brain-computer interfaces as a new communication channel has become an interest topic, nevertheless, there are many challenges to achieve a natural communication. In the particular case of imagined speech BCIs, there are difficulties to analyze the brain signals. In this work, a bag of features representation to identify patterns in electroencephalograms is explored. This method has ...

Brain Computer Interface (BCI) can help patients of neuromuscular diseases restore parts of the movement and communication abilities that they have lost. Most of BCIs rely on mapping brain activities to device instructions, but limited number of brain activities decides the limited abilities of BCIs. To deal with the problem of limited ablility of BCI, this paper verified the feasibility of con...
