There is a renewed surge in percolation-induced transport properties of diverse nanoparticle composites (cf. RSC Nanoscience & Nanotechnology Series, Paul O’Brien Editor-inChief). We note in particular a broad interest in nanocomposites exhibiting sharp electrical property gains at and above percolation threshold, which motivated us to revisit the classical setting of percolation in random resi...

Articles you may be interested in Single-photon and resonance-enhanced multiphoton threshold ionization of the allyl radical Single-photon threshold photoionization spectra for jet-cooled NO have been measured for the v+ =0 and 1 vibrational levels of the X I~+ ground state of NO+. The NO+ rotational state distribution for the v+ =0 level is shown to be perturbed by nearby autoionizing levels, ...

A parameterized threshold nonlinearity, which separates a mixture of signals with any distribution (except for Gaussian), is introduced. This nonlinearity is particularly simple to implement, since it neither uses hyperbolic nor polynomial functions, unlike most nonlinearities used for blind separation. For some specific distributions, the stable region of the threshold parameter is derived, an...

A parameterized activation function in the form of an adaptive threshold for a single-layer neural network, which separates a mixture of signals with any distribution (except for Gaussian), is introduced. This activation function is particularly simple to implement, since it neither uses hyperbolic nor polynomial functions, unlike most other nonlinear functions used for blind separation. For so...

A game-theoretic model of scrip (artificial currency) systems is analyzed. It is shown that relative entropy can be used to characterize the distribution of agent wealth when all agents use threshold strategies—that is, they volunteer to do work iff they have below a threshold amount of money. Monotonicity of agents’ bestreply functions is used to show that scrip systems have pure strategy equi...

A new cost function based on stochastic fuzzy discrimination information measure is introduced in this paper. Focusing on their significant parts, this cost function is used to find the optimal value of threshold for denoising image. It is, in fact, an extension of fuzzy entropy cost function by the present author. Multivariable normal distribution is used for creating focus on significant part...

We study experimentally as well as numerically the transport and generation of light in multiple scattering media with optical gain. By imaging the spatial distribution of light escaping from the side of the sample, the propagation depth is analyzed. Far below and far above random laser threshold, the spatial profile of emission light is independent of pump intensity, while around threshold, th...

Extreme precipitation events have significant environmental consequences because they may cause considerable damages to urban as well as rural areas. The aim of this work is to construct a threshold model which will describe the exceedances over a threshold for the daily precipitation totals over Athens, Greece. The data used are daily precipitation totals recorded at the National Observatory o...

For an epidemic to occur in a closed population, the transmission rate must be above a threshold level. In plant populations, the threshold depends not only on host density, but on the distribution of hosts in space. This paper presents an alternative analysis of a previously presented stochastic model for an epidemic in continuous space (Bolker, 1999, Bull. Math. Biol. 61, 849-874). A variety ...

We demonstrate that both the kT and threshold resummations can be performed in the Collins-Soper resummation formalism by evaluating soft gluon emissions with infrared cutoffs for the longitudinal and transverse loop momenta, respectively. The reason the kT resummation for a parton distribution function leads to suppression in the large b region, b being the conjugate variable of parton transve...
