In its full generality, a time domain can be defined as a set of temporal individuals connected by a set of temporal relations. Different choices for the temporal individuals and/or the temporal relations give rise to different temporal ontologies. In the database context, the most common temporal ontology takes time instants (equivalently, points or moments) as the temporal individuals and a l...

ETRI Journal, Volume 29, Number 1, February 2007 In this paper, we present a time domain combined field integral equation formulation (TD-CFIE) to analyze the transient electromagnetic response from dielectric objects. The solution method is based on the method of moments which involves separate spatial and temporal testing procedures. A set of the RWG functions is used for spatial expansion of...

The hippocampus is critical to remembering the flow of events in distinct experiences and, in doing so, bridges temporal gaps between discontiguous events. Here, we report a robust hippocampal representation of sequence memories, highlighted by "time cells" that encode successive moments during an empty temporal gap between the key events, while also encoding location and ongoing behavior. Furt...

Humor is a uniquely human quality whose neural substrates remain enigmatic. The present report combined dynamic, real-life content and event-related functional magnetic resonance imaging (fMRI) to dissociate humor detection ("getting the joke") from humor appreciation (the affective experience of mirth). During scanning, subjects viewed full-length episodes of the television sitcoms Seinfeld or...

The idea that temporal propositions are vague predicates is examined with attention to the nature of the objects over which the predicates range. These objects should not, it is argued, be identified once and for all with points or intervals in the real line (or any fixed linear order). Context has an important role to play not only in sidestepping the Sorites paradox (Gaifman 2002) but also in...

Space-time paths and prisms are time geographic concepts delimiting the actual and potential mobility pattern of an object in space and time, respectively. While there is a range of similarity measures for space-time paths, it is only recently that researchers started to develop similarity measures for the space-time prism (STP). This paper proposes a new methodology for measuring the similarit...

We experience the world as a seamless stream of percepts. However, intriguing illusions and recent experiments suggest that the world is not continuously translated into conscious perception. Instead, perception seems to operate in a discrete manner, just like movies appear continuous although they consist of discrete images. To explain how the temporal resolution of human vision can be fast co...
