With most internet connections being short–lived (i.e. ~10 segments), it is very tempting to enlarge the TCP Initial Window (IW). This would save two of the three RTTs needed to transfer most of the web pages through a legacy slow start. However it has been demonstrated that the bursts created by a larger IW greatly impair global performance. An intuitive solution is the TCP Pacing. By spreadin...

This paper presents a spreading-activation theory of human semantic processing, which can be applied to a wide range of recent experimental results. The theory is based on Quillian's theory of semantic memory search and semantic preparation, or priming. In conjunction with this, several of the miscondeptions concerning Qullian's theory are discussed. A number of additional assumptions are propo...

In this paper, we describe an extension of the theory of shortterm memory decay for the ACT-R cognitive architecture. By including a short-term decay for elements recently cleared from active memory, we have extended the functionality of spreading activation as a source of implicit contextual information for the model. In ACT-R models of serial memory and decision-making, contextual information...

Almost without exception, acquired language disorders resulting from focal brain injury are accompanied by impairments of verbal short-term memory (STM) and verbal learning. Moreover, disturbances in verbal STM are generally associated with language dysfunction, in some cases mild and not disruptive to most language activities. The co-occurrence of language and mnestic deficits in the aphasic p...

This essay looks at the historical significance of three APS classic papers that are freely available online: Leão AAP. Spreading depression of activity in the cerebral cortex. J Neurophysiol 7: 359–390, 1944 (http://jn.physiology.org/cgi/reprint/7/6/359). Leão AAP. Pial circulation and spreading depression of activity in the cerebral cortex. J Neurophysiol 7: 391–396, 1944 (http://jn.physiolog...

Motivated by the recent emergence of the so-called opportunistic communication networks, we consider the issue of adaptivity in the most basic continuous time (asynchronous) rumor spreading process. In our setting a rumor has to be spread to a population; the service provider can push it at any time to any node in the network and has unit cost for doing this. On the other hand, as usual in rumo...

To analyze the transport process, a formalism was developed similar to charge carrier transport in crystalline materials. Classical electrostatic and electrodynamics treatment with specific boundary conditions were employed. The spreading velocities and deep trapping times were evaluated. By this method we determined the dispersive and spatiotemporal features of the transient charge packets in ...

Modelling how a word is activated in human memory is an important requirement for determining the probability of recall of a word in an extra-list cueing experiment. The spreading activation, spooky-action-at-a-distance and entanglement models have all been used to model the activation of a word. Recently a hypothesis was put forward that the mean activation levels of the respective models are ...

The inequality of bargaining power between employees who do not possess full freedom of association or actual liberty of contract and employers who are organized in the corporate or other forms of ownership association substantially burdens and affects the flow of commerce, and tends to aggravate recurrent business depressions, by depressing wage rates and the purchasing power of wage earners i...
