THE “HAPPY THROUGHT” COT PROTECTOR.

Cot deaths: the aftermath.

Happy Chatbot, Happy User

We compare our own embodied conversational agent (ECA) scheme, BotCom, with seven other complex Internet-based ECAs according to recentlypublished information about them, and highlight some important attributes that have received little attention in the construction of realistic ECAs. BotCom incorporates the use of emotions, humor and complex information services. We cover issues that are likel...

Chromosome Segregation: Disarming the Protector

One of the key features of meiosis is that shugoshin in complex with protein phosphatase 2A (PP2A) protects centromeric cohesin during meiosis I, but not during meiosis II. A new model suggests that a PP2A inhibitor mediates deprotection of centromeric cohesin during meiosis II.

How to protect the protector?

This paper describes ongoing research to harden the lower part of the software stack, normally not covered by existing software-based fault-tolerance mechanisms. I discuss a combination of four techniques to harden the operating system kernel against hardware faults: resilient data structures, asynchronous checks, restartable OS services, and message protection. I present initial performance re...
