Since its original description the diagnosis of word deafness has been greatly expanded. Confusion has arisen with regard to the usage of the related terms pure word deafness, auditory agnosia, and cortical deafness. Three new cases of word deafness are presented including one case with CT and necropsy correlation. These cases are compared with 34 previously reported cases of various cortical a...

Sensor clusters (aka sensor networks) are interesting because of the role they play in distributed data collection. Conventionally, a sensor network designer had to worry about getting data from the sensors to a processing application. This paper argues that dedicated data collection networks are better suited to this data collection task. Like the sensor clusters they support, data collection ...

In 1895 Wilhelm Conrad Roentgen was the professor and head of the department of physics at the Julius-Maximillan University at Wurzburg in Germany. On the 8 November of that year, he was working with cathode rays using evacuated glass bulbs. Rontgen noted that when a current was passed across the bulb, a barium platinocyanide screen was seen to fluoresce. He at once realised the significance of...

Holomorphic dynamics has been a key area of study for 100 years. In this survey, we focus on the dynamics of rational functions.

Poliovirus was first isolated nearly 100 years ago in a landmark experiment that established the viral etiology of poliomyelitis. This discovery stimulated investigation of the pathogenesis of poliomyelitis in many laboratories. Nearly 50 years later, when two effective poliovirus vaccines were developed, the impetus to study poliovirus pathogenesis waned. The identification of the cell recepto...

This historical review takes a few selected issues from the rheological studies of extensional flow that fill the literature, starting with extracts from the seminal papers of Trouton (Proc. Roy. Soc. A77 (1906) 426-440) and Fano (Archivio di fisiologio, 5 (1908) 365-370). Work in the first half of the twentieth century on spinnability and extensional viscosity measurement is highlighted, follo...
