ABSTRACT
The lubricant transfer at the head disk interface of hard disk drives was investigated by the direct simulation Monte Carlo method. It was found that the air molecules between the disk and the slider have an effect of shielding the slider surface, preventing the evaporated lubricant molecules from reaching it. We propose a model that well describes the shielding effect and show that the shielding effect has distinct characteristics depending on the Knudsen number.

    While bending and twist can be treated as independent degrees of freedom for linear DNA molecules, the loop closure constraint introduces a coupling between these variables in circular DNA. We performed Monte Carlo simulations of wormlike rods with both bending and twist rigidity in order to...

    The atomic force microscope can be used to forcibly unfold and extend single polypeptide chains. The resulting force versus distance curves have been widely interpreted to arise from the loss of entropy that the unfolded polypeptide chain experiences as it is extended.
