We study nonnegative solutions of two porous medium equations with nonlinear coupled boundary conditions and nonnegative nontrivial compactly supported initial data. We describe them in terms of the ...

Inflation has climbed since 2021, as the labor market has tightened. Two historical data relationships can account for elevated inflation over the past two years: the Beveridge curve, which relates ...

Dynamic traits change their phenotypes with time or other independent variables. A profound understanding of the genetic control of a dynamic trait should include the timing of the underlying genes to ...

Our understanding of avian growth rates can benefit from the use of two statistical approaches that explicitly model the sources of intraspecific variation. First, random effects can evaluate whether ...

Italian scientists have looked at how non-linear degradation curves could affect the profitability of large-scale solar projects. They found that full substitution of the modules after 10 years could ...

Activation functions play a critical role in AI inference, helping to ferret out nonlinear behaviors in AI models. This makes them an integral part of any neural network, but nonlinear functions can ...

New data covering the period since May 2023 have continued to follow the path of a nonlinear Phillips curve that shows the relationship between inflation and a particular measure of labor market slack ...
