It had all the appearances of a conventional sentencing hearing. The accused sat quietly in the front row of the Middleton Court House with his wife beside him, arm in arm. She gave him one last hug after the judge pronounced sentence: five years in a federal institution. Among the small group attending the hearing were two young teenagers, the daughters of the accused. When the judge handed do...

This paper addresses networks of chemically coupled Hindmarsh-Rose neurons. After a brief presentation of the model, two synchronisation phenomena are studied. We first show that the minimal coupling strength needed to obtain complete synchronisation only depends on the in-degree of the network nodes and follows a power law. Then we propose an algorithm of numerical detection of burst synchroni...

A study has been conducted on amine-cured epoxy resins and the effects on the ultimate burst strength of internally loaded glass-reinforced filament-wound vessels when these rosins were used as the plastic matrices. The tensile properties of the niatrLx were changed by systematically altering the molecular structure of the amine-cured epoxy resin. It was found that resintensile properties had a...

this study was performed to investigate the effects of refining on the mechanical and optical properties of waste newspaper. waste newspapers were prepared from gorgan ettelaat newspaper agency and were cut to 5 centimeter pieces, and then were soaked with sufficient distillated water. after 1 day fibers were separated by disintegrator and freeness values for each pulp before and after refining...

In this paper, the stress rupture reliability of Carbon/Epoxy Composite Overwrapped Pressure Vessels (COPVs) is examined utilizing the classic Phoenix model and accounting for the differences between the design and the actual burst pressure, and the liner contribution effects. Stress rupture life primarily depends upon the fiber stress ratio which is defined as the ratio of stress in fibers at ...

Rock burst is the most attractive and hot research area in geomechanics, mining, and civil engineering due to the increasing depth of mines and construction of deep underground structures. It has also been a severe problem in ground control measures in the last few decades. Many studies have been done by different researchers in order to minimize the hazards of rock burst and to provide a safe ...

Hippocampal cells often fire prolonged bursts of action potentials, resulting in dynamic modulation of postsynaptic responses; yet long-term potentiation (LTP) has routinely been studied using only single presynaptic stimuli given at low frequency. Recent work on neocortical synapses has suggested that LTP may cause a "redistribution of synaptic strength" in which synaptic responses to the firs...
