where they can be detected by a production system that responds to patterns of information in the buffers. At any point in time a single production rule is selected to respond to the current pattern. Subsymbolic processes serve to guide the selection of rules to fire as well as the internal operations

Abstract. Fire Regime Condition Class (FRCC) has been developed as a nationally consistent interagency method in the US to assess degree of departure between historical and current fire regimes and vegetation structural conditions across differing vegetation types. Historical and existing

in most circumstances. FIRE is empirically benchmarked and is shown to help agents effectively select appropriate interaction partners.

Patterns of neural firing linked to eye movement decisions show that behavioral decisions are predicted by the differential firing rates of cells coding selected and nonselected stimulus alternatives. These results can be interpreted using models developed in mathematical psychology to model

and that the generally accepted input- (or synapse-) specific rule for modification appears not to be strictly adhered to. Spike timing– dependent modifications, together with selective spread of synaptic changes, provide a set of cellular mechanisms that are likely to be important for the development and functioning

We analyze the following (solitaire) game: each node of a graph contains a pile of chips, and a move consists of selecting a node with at least as many chips on it as its degree, and let it send one chip to each of its neighbors. The game terminates if there is no such node. We show

Temporally selective firing of cortical and thalamic neurons during sleep and wakefulness:

Using noninvasive functional magnetic resonance imaging (fMRI) techniques, we analyzed the responses in human area MT with regard to visual motion, color, and luminance contrast sensitivity, and retinotopy. As in previous PET studies, we found that area MT responded selectively to moving (compared

and evolutionary biology to provide this linkage. Ecosystem functioning is the end result of the operation of multiple environmental filters in a hierarchy of scales which, by selecting individuals with appropriate responses, result in assemblages with varying trait composition. Functional linkages and trade

Specific risks are associated with working in a chemical laboratory. An emergency situation in a laboratory may involve a fire, explosion, chemical hazard or major spill. This guideline details the procedures to follow to minimise the impact of a major incident on the safety of people and property
