Videoconferencing is becoming a commonplace facility. In the past this has been over dedicated lines, but increasingly, communities are experimenting with video and audio over today’s packet switched digital networks without using very expensive quantities of bandwidth, in attempt to economise by using the existing communications infra-structure. This paper is about traffic characterisation and...

Web-based malware is pervasive. Miscreants compromise insecure hosts or even set up dedicated servers to distribute malware to unsuspecting users. This scourge is mainly fought by the voluntary action of private actors who detect and report infections to affected site owners, hosting providers and registrars. In this paper we describe an experiment to assess whether sending reports to affected ...

Beam-type collisional activation dissociation (HCD) offers many advantages over resonant excitation collision-activated dissociation, including improved identification of phosphorylated peptides and compatibility with isobaric tag-based quantitation (e.g. tandem mass tag (TMT) and iTRAQ). However, HCD typically requires specially designed and dedicated collision cells. Here we demonstrate that ...
