Mode & communication environnementale

Cell communication by periodic cyclic-AMP pulses.

At the surface of aggregating cells of the slime mould, Dictyostelium discoideum, two different sites interacting with extracellular cAMP are detectable: binding sites and cycl-nucleotide phosphodiesterase. Both sites are developmentally regulated. An adequate stimulus for the chemoreceptor system in D. discoideum is the change of cAMP concentration in time, rather than concentration per se: lo...

Current Mode based Communication System

Abstract: This paper focuses on the various advantages of current mode circuits over the widely used voltage mode circuits in communication system. The individual blocks of a basic communication system are designed in voltage mode and the circuits are then converted into their equivalent voltage mode. Conclusions are drawn based on the various responses observed in both the modes. The existing ...

The logically instantaneous communication mode: a communication abstraction

Communication is Logically Instantaneous (li) when there is a logical time frame in which for each message, the send event and the corresponding delivery events occur simultaneously. li is stronger than Causally Ordered (co) communication, but weaker than Rendezvous (rdv) communication. This paper explores Logically Instantaneous communication and provides a simple and eecient protocol that imp...

An Adaptive HW/SW Dual Communication Mode

HW/SW communication mode makes significant impact on HW/SW communication efficiency. Based on the characteristics of the hardware functions, this paper presents an adaptive HW/SW dual communication mode according to the traffic between the hardware and software, and builds an adaptive decision algorithm to choose HW/SW communication mode. The algorithm combining the simulated annealing and chai...
