We argue that the string theory dual to a certain sector of the four-dimensional Yang-Mills theory at large-N is the A-model wrapping N Lagrangian Dbranes on the twistor space of the complex two-dimensional projective space, with a certain flux and Wilson loop background, by finding that the targetspace beta function of this A-model coincides with the large-N beta function of the Yang-Mills the...

An ongoing debate concerns whether spoken word recognition happens in an incremental or continuous manner (Marslen-Wilson & Zwitserlood, 1989; McClelland & Elman, 1986). In the current study, participants (31 adults and 49 infants aged 24-30months) were presented with four images while they heard a sentence like “Look at the cat”. Among the images was one object that rhymed with the spoken word...

In a remarkable work of social history called More Work for Mother: The Ironies of Household Technology from the Open Hearth to the Microwave, Ruth Cowan examines the effects of new technologies in the kitchen. Her main conclusion: new technologies like stoves (which were invented in the 18 century and replaced traditional cooking on the open hearth) did not generally make less work for mother....

A critical property of the perception of spoken words is the transient ambiguity of the speech signal. In localist models of speech perception this ambiguity is captured by allowing the parallel activation of multiple lexical representations. This paper examines how a distributed model of speech perception can accommodate this property. Statistical analyses of vector spaces show that coactivati...

Abundance comparisons of neutron-capture elements – those formed in slow (sprocess) and rapid (r-process) neutron-capture nucleosynthesis – are providing important new information about the nature of the earliest Galactic nucleosynthesis and the first stellar generations (see recent reviews by Truran et al. 2002, Sneden & Cowan 2003 and Cowan & Thielemann 2004). Most previous studies have been ...

Many information systems (IS) programs have been touting the positive economic outlook and opportunities for IS graduates as a strategy for increasing enrollment. Today, the unemployment rate is the highest its been in 25 years with the unemployment rate for college graduates the highest since the U.S. government started keeping records (Yang 2009). The purpose of this panel is to discuss strat...

We study the unitary matrix model with a topological term. We call the topological term the theta term. In the symmetric model there is the phase transition at λc = 2. If the Wilson term is larger than the theta term, there is the phase transition at the same λc. On the other hand, if the theta term is larger than the Wilson term, there is no phase transition.

We compute the circular Wilson loop ofN = 4 SYM theory at large N in the rank k symmetric and antisymmetric tensor representations. Using a quadratic Hermitian matrix model we obtain expressions for all values of the ’t Hooft coupling. At large and small couplings we give explicit formulae and reproduce supergravity results from both D3 and D5 branes within a systematic framework. 1. Background...
