Is this difference a matter of quality or degree? Many people have had dreams of intense, prolonged falling, even though they have never fallen from such heights before. Perhaps vestibular-somatosensory responses, a...

Pek et al. describe how a stable, intron-derived RNA regulates the expression of its host gene during Drosophila embryogenesis. Once they are spliced out of nascent mRNAs, noncoding intron sequences are usually degraded rapidly. At least in Xenopus eggs and human cell lines, however, some intronic RNAs persist for long periods, although the function of these stable intronic sequence (sis) RNAs ...

This paper gives an up-to-date estimate of the costs of road accidents in Iran. Conventional methods of estimating costs are considered together with special factors which apply to Iran. An attempt is made to quantify direct and indirect costs of accidents, including considerations relating to the exercise of Shar'ia law. The overall results show that road accidents account for between 1.4 and ...

Privacy-preserving digital credentials are cryptographic tools that allow a user to prove a predicate about his/her identity or qualifications, without the verifying party learning additional information beyond the status of that predicate. The Identity Mixer (Idemix) [CL01] is a framework providing such credentials. In Idemix, we can distinguish two types of credentials: (1) one-time show cred...

A short segment on Alice has been used in introductory programming classes. The intent was to introduce objects in an easily accessible way. In the third iteration of this approach a presentation was made on quality issues in dramatics. The students were instructed on how to make the video more entertaining. Although this may be accomplished in a class hour or less, the results were encouraging...
