They argued that the spectrum may appear continuous because the electrons can easily lose energy by breamsstrahlung in material. The ma ...

Particle Based Visualization of Stress Distribution Caused by the Aortic Valve Deformation
... aortic valve is treated as the elastic body and the blood is treated as Herschel-Bulkley fluid. The deformation has been calculated by an implicit method using MPS in order to perform stable transformation. In addition, the pressure of the fluid and the repulsive force between surface particles of the ...

The BEH Mechanism and its Scalar Boson by François Englert
... bosons in the theory, we turn our attention to a class of theories where the state of a system is asymmetric with respect to the symmetry principles that govern its dynamics. This is often the case in the statistical physics of phase transitions [3]. This is not surprising, since more often than not ...
