Abstract This paper reports the fabrication of an artificial synapse (AS) based on two-dimensional molybdenum disulfide (MoS 2 ) film. The AS emulates important synaptic functions such as paired-pulse facilitation, spike-rate dependent plasticity, spike-duration plasticity and spike-number plasticity. spike voltage can mediate ion migration in gel to regulate conductance MoS channel, thereby re...

Instrumented indentation tests are an efficient approach for the characterization of stress–strain curves instead tensile or compression and have recently been applied evaluation mechanical properties at elevated temperatures. In high-temperature tests, rate dependence load appears to be dominant. this study, strain-rate-dependent plasticity in instrumented high temperatures was characterized t...

A coupling between phase transformation and viscoplasticity is observed in HTSMAs during actuation. The dislocations generated retained phases accumulated are responsible for the coupling. It results functional fatigue, which reflected as an alteration properties of alloy, increase irrecoverable deformations. objective present study was to develop a theoretical framework account interactions si...

Previous attempts at integrating spike-timing dependent plasticity rules in the NEF have met with little success. This project proposes a spike-timing dependent plasticity rule that uses local information to learn transformations between populations of neurons. The rule is implemented and tested on a simple one-dimensional communication channel, and is compared to a similar rate-based learning ...

Long-term modification of synaptic strength is one of the basic mechanisms of memory formation and activity-dependent refinement of neural circuits. This idea was purposed by Hebb to provide a basis for the formation of a cell assembly. Repetitive correlated activity of pre-synaptic and post-synaptic neurons can induce long-lasting synaptic strength modification, the direction and extent of whi...

In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependant plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependant plasti...
