the purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for dierent family of reactionterms. we...

in this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (anfis) for canceling maternal electrocardiogram (mecg) in fetal electrocardiogram extraction (fecg).this technique is used to estimate the mecg present in the abdominal signal of a pregnant woman. the fecg is then extracted by subtracting the estimated mecg from the abdominal signal. p...

Previous research suggests that mass incarceration in the United States may have contributed to lower rates of violent crime since the 1990s but, surprisingly, finds no evidence of an effect of imprisonment on violent crime prior to 1991. This raises what Steven Levitt has called “a real puzzle.” This study offers the solution to the puzzle: the error in all prior studies is that they focus exc...

We use weighted mean and median statistics techniques to combine individual estimates of ΩM0, the present mean mass density in non-relativistic matter, and determine the observed values and ranges of ΩM0 from different combinations of data. The derived weighted mean ΩM0 values are not good representatives of the individual measurements, under the assumptions of Gaussianity and negligible correl...

The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...

An anecdotal introduction to dimensional theory is used to focus on the issue of combining samples that differ allometrically with size. None of the ideas are original with the author. Indeed, the principles are well-known. Proponents of the body mass index who propose a common scale for individuals 20 to 65 years old blatantly ignore them. The error of combining samples is demonstrated using l...

In this work, two models are proposed for electricity prices as energy commodity prices which in addition to mean-reverting properties have jumps and spikes, due to non-storability of electricity. The models are simulated using an Euler scheme, and then the Monte-Carlo method is used to estimate the expectation of the discounted cash-flow under historical probability, which is considered as the...
