Recent Experimental Results from HELIOS

Recent Theoretical and Experimental Results

We consider a wireless ad hoc network with single antenna nodes under a two-hop relay traffic pattern. Some of the nodes in the network form source/destination pairs, while the other nodes serve as amplify and forward relays. The relay gains are assigned such, that the interference between different source/destination links is nulled (multiuser zero forcing relaying; MU-ZFR). This essentially r...

The Physics of Charm: Recent Experimental Results

We review the most recent results from experiments studying systems containing charmed quarks. The selection reflects the presenter’s bias, and there is an emphasis on decays of open charm. We discuss precision measurements of various sorts, various new states in the charmonium system, measurements aimed at testing Lattice QCD, and the latest searches for charm mixing. We conclude with a discus...

From Helios to Zeus

We present Zeus, a verifiable internet ballot casting and counting system based on Helios, in which encrypted votes are posted eponymously to a server, then are anonymized via cryptographic mixing, and finally are decrypted using multiple trustee keys. Zeus refines the original Helios workflow to address a variety of practical issues, such as usability, parallelization, varying election types, ...

OMEGA Experimental Program and Recent Results

LLE Review, Volume 72 161 The Laboratory for Laser Energetics (LLE) with its OMEGA facility is part of the national laser-fusion effort within the U.S. Department of Energy and has as its main mission direct-drive laser-fusion research in support of the upcoming National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory (LLNL). The upgraded OMEGA laser system has been in ope...
