A new rate-dependent plasticity model for dilative granular media is presented, aiming to bridge the seemingly disparate solidand fluid-like behavioral regimes. Up to date, solid-like behavior is typically tackled with rate-independent plasticity models emanating from Mohr–Coulomb and Critical State plasticity theory. On the other hand, the fluid-like behavior of granular media is typically tre...

In this paper the studies of the two-phase super Plasticity stainless steels is studied. The aim of this study obtained the suitable criteria to thermo-mechanical treatment condition for decrease the microstructure (grain size) and super plasticity property in two-phase stainless steels. Also here we want to show the appropriate ranges of temperature and strain rate used in the process super pl...

In spike-timing-dependent plasticity (STDP), the order and precise temporal interval between presynaptic and postsynaptic spikes determine the sign and magnitude of long-term potentiation (LTP) or depression (LTD). STDP is widely utilized in models of circuit-level plasticity, development, and learning. However, spike timing is just one of several factors (including firing rate, synaptic cooper...

morphine’s effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. the present study intended to investigate whether administration of morphine ...

Rate based (Bienenstock-Cooper-Munroe, BCM) and spike timing dependent plasticity (STDP) are the two principal learning behaviors found at cortical synapses. Some BCM induction protocols have been shown to be compatible with STDP rules, thus combining both forms of plasticity. However, we demonstrate that the majority of actual experimental BCM protocols cannot be reproduced by STDP. This sensi...
