How species form: What the tangled history of polar bear and brown bear relations tells us It’s complicated. Rather than simple splitting events, the species histories of polar and brown bears ...

It’s complicated. Rather than simple splitting events, the species histories of polar and brown bears, like those of humans, hide convoluted stories of divergence and interbreeding, study finds.

In section 3 , the derivation of the equations of motion and boundary conditions is carried out. This technique is applied for rectangular and circular plates. 2. Continuum Dynamics In this section, ...

“Rectangular watches have a small but loyal following,” Anthony de Haas, A. Lange & Söhne’s director of product development, wrote in an email. “Our new watch highlights the importance we ...

This article provides a closed form solution to the telegrapher’s equation with three space variables defined on a subset of a sphere within two radii, two azimuthal angles and one polar angle. The ...
