Do destinations have multiple lifecycles?

Multiple Access for Multiple Destinations in Ad Hoc Networks

In this paper, we address the medium-access control (MAC) problem in systems with multiple destinations, a problem that is crucial to the development of ad hoc networks. We focus on collision-resolution algorithms, specifically on First-Come, First-Serve (FCFS) splitting algorithms. We illustrate the difficulties that arise because of the interference between two populations of nodes that share...

Cannabinoids in multiple sclerosis: do they have a therapeutic role?

This is an exciting time for cannabinoid research. Evidence suggests that cannabis (marijuana) can alleviate symptoms like muscle spasticity and pain in patients with multiple sclerosis (MS). Interest in the field of cannabinoids has been strengthened by the identification and cloning of cannabinoid receptors located in the central nervous system and the peripheral immune organs, and by the dis...

Agents with non-anthropomorphic lifecycles

Most software agent lifecycles are designed in such a way that they mimic the lifecycles of humans (anthropomorphism). This position paper presents a set of operations for software agents which have no immediate biological analogies, such as splitting and merging agents. We argue through a series of scenarios the potential benefits of this approach. We present a method to implement these operat...

Do Sentences Have Tense?

A fact often not made explicit by syntacticians is that these labels need to be interpreted in semantics. The semantics of tenses has been formulated as a theory of temporal reference since the seminal work of Reichenbach (1947). Subsequently this theory has been integrated into a theory of context change, which widens the domain of tense semantics from the sentence to discourse (Kamp. 1979, Ka...
