For decades, Bessel van der Kolk, a psychiatrist whose ideas about how the body records pain helped millions find language for their suffering, has been regarded as the world’s leading expert in the ...

Bessel functions, central to many problems in mathematical physics, provide solutions to differential equations that describe wave propagation, heat conduction and vibrations in cylindrical or ...

When it comes to weight-resistance exercise, you can choose free weights such as dumbbells or barbells. Or weight machines, which are often driven by cables or levers. You can use resistance bands or ...

Many people have low-level risk factors, such as early signs of heart disease, smoldering inside their body. But they can only take preventative action if aware of potential threats. That’s the ...

Abstract: The spherically layered media (SLM) theory has wide applications for electromagnetic wave scattering analysis. Due to the involved Bessel functions, the traditional formulations of the SLM ...
