In order to efficiently explore the nearly infinite composition space in multicomponent solid solution alloys for reaching higher mechanical performance, it is important establish predictive design strategies using computation-aided methods. Here, ab initio calculations we systematically study effects of magnetism and chemical on generalized stacking fault energy surface (γ-surface) Cr-Co-Ni me...

Abstract   In this study, generalized differential quadrature analysis of elastic/plastic buckling of skew thin plates is presented. The governing equations are derived for the first time based on the incremental and deformation theories of plasticity and classical plate theory (CPT). The elastic/plastic behavior of plates is described by the Ramberg-Osgood model. The ranges of plate geometries...

the effect of cysteamine, a somatostatin depletor, on synaptic plasticity induced by tetanic and paired-pulse stimulation was investigated in rat hippocampal ca1. for this purpose, hippocampal slices from saline (1 ml/kg, s.c.) and cysteamine (200 fig/kg, s.c.)-treated and intact rats were used. population spikes were recorded following schaffer collateral stimulation. to induce ltp, primed bur...

Different from nonvolatile memory applications, neuromorphic computing applications utilize not only the static conductance states but also switching dynamics for computing, which calls compact dynamical models of memristive devices. In this work, a generalized model to simulate diffusive and drift memristors with same set equations is presented, have been used reproduce experimental results fa...

The advancement of microstructure-sensitive models for elevated temperature applications requires experimental data at the relevant length scales and usage environments. Towards this goal, we studied evolution grain-level strains in a Ni-based superalloy during heating subsequent loading temperature. specimen was heated using two halogen lamps furnace designed explicitly special load frame used...

in this paper direct proofs of some common fixed point results for two and three mappings under weak contractive conditions are given. some of these results are improved by using different arguments of control functions. examples are presented showing that some generalizations cannot be obtained and also that our results are distinct from the existing ones.

in this paper, we deal with molaei’s generalized groups. we definethe notion of a fuzzy generalized subgroup with respect to a t-norm (ort-fuzzy generalized subgroup) and give some related properties. especially,we state and prove the representation theorem for these fuzzy generalizedsubgroups. next, using the concept of continuity of t-norms we obtain a correspondencebetween tf(g), the set of ...

Our recent studies show that chronic oral nicotine partially protects against striatal damage in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated nonhuman primates. To identify the cellular changes associated with this protective action, we investigated the effects of nicotine treatment on stimulus-evoked dopamine release, dopamine turnover, and synaptic plasticity in striatum from l...

Nanocrystalline (NC) metals with grain sizes <100 nm have attracted a lot of attention in the materials science fi eld for more than a few decades because of their ultra-high strength and hardness. Various experimental and computational studies indicate that dislocation-mediated plasticity prevails in NC metals when the grain size is larger than ~10 nm. Recent molecular dynamics (MD) simulation...
