DOI: 10.1007/s12928-020-00674-2
Abstract: We evaluated the factors that increase the maximum static friction force between the anchoring balloon and the vessel wall. The anchor technique in percutaneous coronary intervention (PCI) may be better supported by a guiding catheter.… read more here.

Abstract: We present an experiment in which we measure the static friction force necessary for a cylinder to roll without slipping on a horizontal surface. Additionally, we introduce an alternative formulation of the rolling condition, based… read more here.

Abstract: In the textbook formulation of dry friction laws, static and dynamic friction (stick and slip) are qualitatively different and sharply separated phenomena. However, accurate measurements of stick-slip motion generally show that static friction is not… read more here.
