This paper proposes a new method for searching two-valued (binary) game trees in games like chess or Go. Lambda-search uses null-moves together with different orders of threat-sequences (so-called lambda-trees), focusing the search on threats and threat-aversions, but still guaranteeing to find the minimax value (provided that the game-rules allow passing or zugzwang is not a motive). Using neg...

Active learning (AL) is often used in corpus construction (CC) for selecting “informative” documents for annotation. This is ideal for focusing annotation efforts when all documents cannot be annotated, but has the limitation that it is carried out in a closed-loop, selecting points that will improve an existing model. For phenomena-driven and exploratory CC, the lack of existing-models and spe...

In open and dynamic environments, agents will usually differ in the domain ontologies they commit to and their perception of the world. The availability of Alignment Services, that are able to provide correspondences between two ontologies, is only a partial solution to achieving interoperability between agents, because any given candidate set of alignments is only suitable in certain contexts....

The work described in this paper presents an approach on scheduling in a virtual enterprise in the tourism sector. This scheduling scenario has to reconcile customers’ and service providers’ interests. That is, the customer’s temporal constraints on when to consume the service, and the service provider’s preferences on when to accept a booking. An algorithm is being developed for this situation...

The PS Move, Kinect, and Wii tout their technological capabilities as evidence that they can best support intuitive, creative movements. However, games for these systems tend to use their technology to hold the player to higher standards of conformity. This style of game design can result in the player being made to 'fit' the game, rather than the other way around. It is worthwhile to explore a...

We demonstrate that the tunable potential introduced by a surface acoustic wave on a homogeneous polariton condensate leads to fragmentation of the condensate into an array of wires which move with the acoustic velocity. Reduction of the spatial coherence of the condensate emission along the surface acoustic wave direction is attributed to the suppression of coupling between the spatially modul...

We propose to include gravity in quantum field theory non-perturbatively by modifying the propagators so that each virtual particle in a Feynman graph move in the space-time determined by the momenta of the other particles in the same graph. We then obtain a modified Feynman propagator for the massless neutral scalar field which shows a suppression at high momentum strong enough to entail finit...

The function of verbal short-term memory is supported not only by the phonological loop, but also by semantic resources that may operate on both short and long time scales. Elucidation of the neural underpinnings of these mechanisms requires effective behavioral manipulations that can selectively engage them. We developed a novel cued sentence recall paradigm to assess the effects of two factor...

OBJECTIVES To study whether the growth hormone (GH) response after the subcutaneous administration 50 microg of octreotide (acute octreotide test) has any predictive value for long-term IGF-I normalization with Sandostatin LAR. DESIGN Twenty four therapy-naive patients with active acromegaly were studied. RESULTS > 75% GH decrease in the acute octreotide test predicted long-term IGF-I norma...
