A large mass hierarchy from a small extra dimension

by Lisa Randall , 1999
"... We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from a large scale of order the Planck scale through an exponential hierarchy. However, this exponential arises not from gauge interactions but from the background metric (which is a slice of ..."

. There are fundamental spin-2 excitations with mass of weak scale order, which are coupled with weak scale as opposed to gravitational strength to the standard model particles. The phenomenology of these models is quite distinct from that of large extra dimension scenarios; none of the current If spacetime

Parallel Networks that Learn to Pronounce English Text

by Terrence J. Sejnowski, Charles R. Rosenberg - COMPLEX SYSTEMS , 1987
"... This paper describes NETtalk, a class of massively-parallel network systems that learn to convert English text to speech. The memory representations for pronunciations are learned by practice and are shared among many processing units. The performance of NETtalk has some similarities with observed h ..."

is essential. (iv) Relearning after damage is much faster than learning during the original training. (v) Distributed or spaced practice is more effective for long-term retention than massed practice. Network models can be constructed that have the same performance and learning characteristics on a particular

Loopy belief propagation for approximate inference: An empirical study. In:

by Kevin P Murphy , Yair Weiss , Michael I Jordan - Proceedings of Uncertainty in AI, , 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

Practical animation of liquids

by Nick Foster, Dimitri Metaxas - Graphical Models and Image Processing , 1996
"... We present a comprehensive methodology for realistically animating liquid phenomena. Our approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior. It is based on the Navier-Stokes equations which couple momentum and mass con ..."

The string dual of a confining four-dimensional gauge theory

by Joseph Polchinski, Matthew J. Strassler , 2000
"... We study N = 1 gauge theories obtained by adding finite mass terms to N = 4 Yang-Mills theory. The Maldacena dual is nonsingular: in each of the many vacua, there is an extended brane source, arising from Myers’ dielectric effect. The source consists of one or more (p,q) 5-branes. In particular, the ..."

Particle-Based Fluid Simulation for Interactive Applications

by Matthias Müller, David Charypar, Markus Gross , 2003
"... Realistically animated fluids can add substantial realism to interactive applications such as virtual surgery simulators or computer games. In this paper we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate fluids with free surfaces. The method is an extension ..."

of the SPH-based technique by Desbrun to animate highly deformable bodies. We gear the method towards fluid simulation by deriving the force density fields directly from the Navier-Stokes equation and by adding a term to model surface tension effects. In contrast to Eulerian grid-based approaches

Multiagent systems

by Katia P. Sycara - AI Magazine , 1998
"... ■ Agent-based systems technology has generated lots of excitement in recent years because of its promise as a new paradigm for conceptualizing, designing, and implementing software systems. This promise is particularly attractive for creating software that operates in environments that are distribu ..."

is becoming apparent. Central to the design and effective operation of such multiagent systems (MASs) are a core set of issues and research questions that have been studied over the years by the distributed AI community. In this article, I present some of the critical notions in MASs and the research work

The Effects of Financial Education in the Workplace: Evidence from a Survey of Employers.” NBER Working Paper No. 5655. Cambridge, Mass.: National Bureau of Economic Research

Thematic relations as links between nominal reference and temporal constitution

by Manfred Krifka , 1992
"... This paper treats the correspondence between the reference type of NPs (i.e., mass nouns, count nouns, measure constructions, plurals) and the temporal constitution of verbal predicates (i.e., activities, accomplish-ments). A theory will be developed that handles the well known influence of the refe ..."

Worms: Identifying Impacts on Education and Health in the presence of Treatment Externalities

by Edward Miguel, Michael Kremer - ECONOMETRICA , 2004
"... Intestinal helminths—including hookworm, roundworm, whipworm, and schistosomiasis—infect more than one-quarter of the world’s population. Studies in which medical treatment is randomized at the individual level potentially doubly underestimate the benefits of treatment, missing externality benefits ..."
