A 36× enlarged triply periodic porous cube of photocured polymer, 60 millimeters in total length, shown refl ected off a pool of uncured resin. Computer-aided design makes it possible to tailor materials with control over porosity, pore size, and mechanical properties. These materials may subsequently fi nd use as scaffolds for tissue engineering and cell-laden hydrogel constructs. See the spec...

Introduction: urban challenges of a transitional period

Stateless connections

We describe a secure transformation of stateful connections or parts of them into stateless ones by attaching the state information to the messages. Secret-key cryptography is used for protection of integrity and con dentiality of the state data and the connections. The stateless protocols created in this way are more robust against denial of service resulting from high loads and resource exhau...

Stateless Geocasting

We present two stateless algorithms that guarantee to deliver the message to every device in a designated geographic area: flooding and planar geocasting. Due to the algorithms’ statelessness, intermediate devices do not have to keep message data between message transmissions. We formally prove the algorithms correct, estimate their message complexity and evaluate their performance through simu...
