Non-adapting superior cervical ganglion (SCG) neurones with a clustering activity and sub-threshold membrane potential oscillations were occasionally recorded, suggesting the presence of a persistent sodium current (I(NaP)). The perforated-patch technique was used to establish its properties and physiological role. Voltage-clamp experiments demonstrated… (More)
In this note we study uncertainty sequencing situations, i.e., 1-machine sequencing situations in which no initial order is specified. We associate cooperative games with these sequencing situations, study their core, and provide links with the classic sequencing games introduced by Curiel et al. (1989). Moreover, we propose and characterize two simple cost… (More)
The basis of rhythmic activity observed at the dorsal column nuclei (DCN) is still open to debate. This study has investigated the electrophysiological properties of isolated DCN neurones deprived of any synaptic influence, using the perforated-patch technique. About half of the DCN neurones (64/130) were spontaneously active. More than half of the… (More)
This paper considers sequencing situations with due date criteria. Three diierent t ypes of criteria are considered: the weighted penalty criterion , the weighted tardiness criterion and the completion time criterion. The main focus is on convexity of the associated cooperative games.
We present a new allocation rule for the class of balanced games: the core-center. This allocation rule selects a centrally located point within the core of a balanced game. Different interpretations supporting this solution are given and a study of its main properties is carried out.
In this paper we answer a question posed by Sertel and¨Ozkal-Sanver (2002) on the manipulability of optimal matching rules in matching problems with endowments. We characterize the classes of consumption rules under which optimal matching rules can be manipulated via predonation of endowment.
