In ad hoc networks, devices are required to self-organize themselves into a network without previously established infrastructure. The kind of ad hoc network we consider in this paper is made up of a multitude of relatively low mobility , short range, wireless devices, pervasively deployed throughout the environment. One of the most important design(More)
—This paper introduces the neuRFon™ Netform, a self-organizing wireless network for low data rate, low-power fixed sensor nodes. The protocol utilizes a logical backbone architecture through which data communications between all the network nodes are supported by hierarchical routing. We present algorithms that underpin the self-organizing features. The(More)
A comparative study of the expression of metabotropic glutamate receptor 2/3 (mGluR2/3) was done in the hippocampus of rats and mice after pilocarpine-induced status epilepticus (APISE), and of patients with mesial temporal lobe epilepsy. At 1 day APISE, there was a marked increase in mGluR2/3 immunoreactivity in the stratum lacunosum moleculare (SLM) of(More)
In CA1 area and the hilus of the dentate gyrus of the mouse hippocampus, drastic reduction of NeuN, calbindin, calretinin, or parvalbumin immunopositive neurons was shown at 3, 7 and 60 days after pilocarpine-induced status epilepticus. In gliotic CA1 area at 60 days, few dendritic branches of calcium binding protein immunopositive neurons could be found(More)
In this paper we simulate a multi-hop self-organizing wireless sensor network. The purpose of the simulation is to investigate, quantitatively, the performance of our self-organizing network design. In particular, we examine such parameters as network formation time, data packet delivery performance, throughput, and device duty cycle. In addition, we(More)
The effects of bis(7)-tacrine, a novel acetylcholinesterase inhibitor, on ischemia-induced cell death and apoptosis were investigated in primary cerebral cortical astrocytes of mice. Following a 6 h in vitro ischemic incubation of the cultures, a marked decrease in the percentage of viable cells was observed by lactate dehydrogenase (LDH) release assay.(More)
