Journal of Modern Optics, 2017 We know that in empty space there is no preferred state of rest. This is true both in special relativity but also in Newtonian mechanics with its associated Galilean relativity.

Investment Frictions versus Financing Frictions [PDF]
SSRN Electronic Journal, 2009 Bertola/Caballero (1994) and Abel/Eberly (1996) extended Jorgenson's classical model of firms' optimal investment. By introducing investment frictions, they were able to capture the role of future anticipations in investment decisions as well as the lumpy and intermittent nature of investment dynamics. We extend Jorgenson's model to the other direction

Superhydrophobic frictions [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance The matchless mobility of water on superhydrophobic materials is often considered as the hallmark of water repellency. The friction of drops is indeed found to be unusual: instead of observing classical friction such as due to contact line and liquid viscosity, we show that the main source of resistance to the water motion arises

SSRN Electronic Journal, 2013 The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a multi-city general equilibrium model to address this question at three different levels: Do spatial frictions ...

Shear Thickening of Dense Suspensions: The Role of Friction [PDF]
, 2019 Shear thickening of particle suspensions is characterized by a transition between lubricated and frictional contacts between the particles. Using 3D numerical simulations, we study how the inter-particle friction coefficient influences the effective ...
