Protein molecules in solution exist as an equilibrium of different conformations, but the sizes and shifts of these populations cannot be determined from static structures. A report now shows how they ...
The realization of the mechanical nonreciprocity requires breaking either the time-reversal symmetry or the material deformation symmetry. The time-reversal asymmetry was the commonly adopted approach ...
It has been demonstrated that particles reach a dynamic equilibrium level in normal operating machines. The theory is based on the fact that if particles are generated at a constant rate and are then ...
