We build a dynamic equilibrium model of a durable goods oligopoly with a competitive secondary market to evaluate the bias in estimating the structural parameters of demand and supply when durability is omitted. We simulate data from our dynamic model and use them to estimate the model’s static counterpart. We find that the static estimate of the elasticity of demand is an overestimate of the t...

Threshold voltage shifts associated with negative gate bias temperature instability in p-channel power VDMOSFETs under the static and pulsed stress conditions are analysed in terms of the effects on device lifetime. The pulsed bias stressing is found to cause less significant threshold voltage shifts in comparison with those caused by the static stressing, which is ascribed to the effects of dy...

PMOS stress (ON) probability has a strong impact on circuit timing degradation due to NBTI effect. This paper evaluates how the granularity of stress probability calculation affects NBTI prediction using a state-of-the-art long term prediction model. Experimental evaluations show that the stress probability should be estimated at transistor level to accurately predict the increase in delay, esp...

In this paper, we propose an accurate model for the read static noise margin (SNM). The model includes the effects of soft oxide breakdown (SBD), negative and positive bias temperature instabilities (NBTI and PBTI, respectively). To assess the accuracy of the proposed model, its predictions are compared with those of HSPICE simulations for 32, and 22 nm technologies. The comparison verifies the...

We discuss two slightly counter-intuitive findings about the environmental dependence of clustering in the Sloan Digital Sky Survey. First, we find that the relation between clustering strength and density is not monotonic: galaxies in the densest regions are more strongly clustered than are galaxies in regions of moderate overdensity; galaxies in moderate overdensities are more strongly cluste...

Motivated by the properties of early universe scenarios that produce observationally large local non-Gaussianity, we perform N-body simulations with non-Gaussian initial conditions from a generalized local ansatz. The bispectra are schematically of the local shape, but with scale-dependent amplitude. We find that in such cases the size of the non-Gaussian correction to the bias of small and lar...

We simulate one-dimensional competitive reversible binding of many diffusing particles to a single, saturable, static site. The particles are initially randomly distributed, and either one or none is initially bound to the site. The time dependence of the binding probability (site occupancy) is compared with an approximation involving singleparticle diffusion with a nonlinear, locally bimolecul...

A linear lumped-parameter mechanical model of the muscle spindle is presented. It is shown that the model simulation exhibits the spindle behavior in most aspects of transient ramp-stretch performance. The requirements that such a model places on the mechanisms of fusimotor control are discussed. Then the efficacy of static γ and dynamic γ stimulation on primary ending output and secondary endi...
