‘Initiation into drug use’ addendum: findings from the DUMA program [PDF]
, 2012 The age at which an individual first experiments with illicit drugs has been of significant interest to policymakers and practitioners, primarily because research has persistently shown a link between early juvenile onset of drug use and less favourable ...

Mean-field optimal control and optimality conditions in the space of probability measures [PDF]
, 2020 We derive a framework to compute optimal controls for problems with states in the space of probability measures. Since many optimal control problems constrained by a system of ordinary differential equations (ODE) modelling interacting particles converge

Quantum Catalysis of Magnetic Phase Transitions in a Quantum Simulator [PDF]
, 2013 We control quantum fluctuations to create the ground state magnetic phases of a classical Ising model with a tunable longitudinal magnetic field using a system of 6 to 10 atomic ion spins.

An assessment of interference cancellation applied to BWA [PDF]
, 2007 It is a general principle that a communication system should be designed to avoid interference in the first place, either through network planning or with effective radio resource management and medium access control.

Discrete Multitone Modulation for Maximizing Transmission Rate in Step-Index Plastic Optical Fibres [PDF]
, 2009 The use of standard 1-mm core-diameter step-index plastic optical fiber (SI-POF) has so far been mainly limited to distances of up to 100 m and bit-rates in the order of 100 Mbit/s.

Mixing and merging for spoken document retrieval [PDF]
, 1998 This paper describes a number of experiments that explo- red the issues surrounding the retrieval of spoken documents. Two such issues were examined. First, attempting to find the best use of speech recogniser output to produce the highest retrieval ...

Quantum Critical Behavior in Gauged Yukawa Matrix Field Theories with Quenched Disorder [PDF]
, 1997 We use the Wilson-Fisher $\epsilon$ expansion to study quantum critical behavior in gauged Yukawa matrix field theories with weak quenched disorder. We find that the resulting quantum critical behavior is in the universality class of the pure system.

MATREX: DCU machine translation system for IWSLT 2006 [PDF]
, 2006 In this paper, we give a description of the machine translation system developed at DCU that was used for our first participation in the evaluation campaign of the International Workshop on Spoken Language Translation (2006).

Long distance decoy state quantum key distribution in optical fiber [PDF]
, 2007 The theoretical existence of photon-number-splitting attacks creates a security loophole for most quantum key distribution (QKD) demonstrations that use a highly attenuated laser source.
