Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
Advanced Functional Materials, EarlyView.A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

A Process Calculus for Mobile Ad Hoc Networks
Science of Computer Programming, 2008 AbstractWe present the ω-calculus, a process calculus for formally modeling and reasoning about Mobile Ad Hoc Wireless Networks (MANETs) and their protocols. The ω-calculus naturally captures essential characteristics of MANETs, including the ability of a MANET node to broadcast a message to any other node within its physical transmission range (and no

Mobility helps security in ad hoc networks [PDF]
Proceedings of the 4th ACM international symposium on Mobile ad hoc networking & computing, 2003 Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are established, when they are in the vicinity of each other, by exchanging appropriate cryptographic ...

A survey of survivability in mobile ad hoc networks [PDF]
IEEE Communications Surveys & Tutorials, 2009 Many efforts have been done towards secure MANETs, but the conventional lines of defense are still inefficient to put all attacks off. This article examines survivable approaches whose goal is to enable networks to fulfill correctly their critical functions even in the presence of attacks or intrusions.
