In this study we obtain the phase line equations for the nematic-smectic A (NA), smectic A-smectic C (AC) and nematic-smectic C (NC) transitions using a mean field model. We fit these phase line equations to the experimental ...

The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related ...

The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ...
