The Gaussian model of discontinuous percolation, recently introduced by Araújo and Herrmann [Phys. Rev. Lett. 105, 035701 (2010)], is numerically investigated in three dimensions, disclosing a discontinuous transition. For the simple cubic lattice, in the thermodynamic limit we report a finite jump of the order parameter J=0.415±0.005. The largest cluster at the threshold is compact, but its ex...

— When the Signal-to-Noise Ratio (SNR) falls below a certain level, the error of the Time-of-Flight (ToF) Maximum Likelihood Estimator (MLE) increases abruptly due to the well-known threshold effect. Nevertheless, operating near and below the threshold SNR value might be necessary for many remote sensing applications due to imposed power-related constraints. These constrains might include a lim...

We investigated the properties of mixed states in a sparsely encoded associative memory model with a structural learning method. When mixed states are made of s memory patterns, s types of mixed states, which become equilibrium states of the model, can be generated. To investigate the properties of s types of the mixed states, we analyzed them using the statistical mechanical method. We found t...

Previous research has found little evidence that banking supervision improves bank performance, possibly because supervision is endogenous to performance. This paper estimates causal effects of supervision on performance using discontinuities in the minimum frequency of examinations imposed by regulation. The bank asset size threshold at which these discontinuities occur changes over time, prov...

Many service systems provide queue length information to customers thereby allowing customers to choose among many options of service. However, queue length information is often delayed and is often not provided in real time. Recent work by Dong et al. [7] explores the impact of these delays in an empirical study in U.S. hospitals. Work by Pender et al. [27] uses a two-dimensional fluid model t...

This paper concerns the use of genetic algorithms for line labelling. We are interested in finding an optimal set of algorithm control parameters for this problem. We give results from using a simple genetic algorithm to solve several line labelling problems and discuss the effects of crossover type, population size, crossover rate, mutation rate and iteration limit on algorithm performance. We...

Quantum error-correcting codes have a distance parameter, conveying the minimum number of single spin errors that could cause error correction to fail. However, the success thresholds of the finite per-qubit error rate that have been proven for the likes of the toric code require them to work well beyond this limit. We argue that, without the assumption of being below the distance limit, the su...

As part of the energy efficient system modeling, which is of interest amongst all areas of research in industry and academia, this paper proposes a design of energy efficient Ethernet access system. The model estimates the feasibility of operating the network interface component under power saving modes, without compromising on the quality of service. In order to prevent degradation of the serv...

a b s t r a c t there are three types of nerve fibers that are involved in the transmission of pain stimuli: c fibers (slower fibers) for thermal, mechanical and chemical stimuli, a-delta fibers for thermal or mechanical stimuli and a-beta fibers for touch stimuli. clinically, this is crucial in making an accurate assessment of the pain level experienced by a suffering patient, in indicating th...

Abstract Peaks-over-threshold analysis using the generalised Pareto distribution is widely applied in modelling tails of univariate random variables, but much information may be lost when complex extreme events are studied results. In this paper, we extend peaks-over-threshold to extremes functional data. Threshold exceedances defined a r modelled by r-Pareto process, generalisation that covers...
