Live Organs from Dead People

Live and Dead Nodes

In this paper, we explore the consequences of a distinction between ‘live’ and ‘dead’ network nodes; ‘live’ nodes are able to acquire new links whereas ‘dead’ nodes are static. We develop an analytically soluble growing network model incorporating this distinction and show that it can provide a quantitative description of the empirical network composed of citations and references (inand out-lin...

Distance Is Dead , Long Live Distance

For many educators, the phrase ‘from distance education to e-learning’ conjures up the view of an ‘evolutionary’ progression beginning with correspondence study and developed through more sophisticated technologies to its current identification with computers, the Internet, and the World Wide Web. For others, particularly those with little knowledge or experience of (and often equally little in...

Dendritic Cells Pulsed with Live and Dead

Is live problem better than dead cert?

Cholecystoduodenal fistula is a type of biliary enteric fistula that can occur as a result of chronic cholecystitis. The majority of cases are diagnosed and their subsequent management planned intraoperatively. Previous reports have focused on successful laparoscopic management. We report three cases of elective cholecystectomy that were diagnosed intraoperatively with a cholecystoduodenal fist...

KASLR is Dead: Long Live KASLR

Modern operating system kernels employ address space layout randomization (ASLR) to prevent control-flow hijacking attacks and code-injection attacks. While kernel security relies fundamentally on preventing access to address information, recent attacks have shown that the hardware directly leaks this information. Strictly splitting kernel space and user space has recently been proposed as a th...
