How Bacteria Handle Copper

Copper in biological systems presents a formidable problem: it is essential for life, yet highly reactive and a potential source of cell damage. Tight control of copper is thus a cellular necessity. To meet this challenge, cells have evolved pumps for transmembranous transport, chaperones for intracellular routing, oxidases and reductases to change the oxidation state of copper, and regulators ...

How to Handle Interacting Concerns?

Concerns in software applications can range from general-purpose concerns such as tracing, synchronization or error handling, to more specific ones such as scheduling in simulation domains or time constraints in real-time systems. An appropriate separation of concerns is supposed to reduce software complexity and improve software evolution, by keeping track of different decomposition criteria (...

How many rounds can Random Selection handle?∗

The construction of zero-knowledge proofs is greatly simplified if the protocol is only required be secure against the honest verifiers. Damg̊ard, Goldreich and Wigderson invented an technique, called Random Selection, to transform a public-coin honest verifier zero-knowledge protocol to a general zero-knowledge protocol [3]. However, it has been widely assumed that the technique itself only wor...

How Best to Handle a Dicey Situation

We introduce the Destructive Object Handling (DOH) problem, which models aspects of many real-world allocation problems, such as shipping explosive munitions, scheduling processes in a cluster with fragile nodes, re-using passwords across multiple websites, and quarantining patients during a disease outbreak. In these problems, objects must be assigned to handlers, but each object has a probabi...
