An international collaboration led by RIKEN researchers has discovered how unusual spherical structures form in the brains of people with a mutation that causes a form of inherited Alzheimer's ...

Thermal stresses in the material of a furnace of approximate spherical form due to differences of temperature, and the stresses due to pressures on the inside and outside surfaces, may be ...

A spherical surface is defined by only one parameter, the radius or curvature of the surface. If the surface is refractive, with different indices of refraction before and after the surface, then the ...
