The adsorption of α-pinene to solid surfaces is an important primary step during the chemical conversion of this common terpene over mesoporous materials, as well as during the formation of atmospheric aerosols. We provide evidence of tight and loose physisorbed states of α-pinene bound on amorphous SiO2 as determined by their adsorption entropy, enthalpy, and binding free energies characterize...

We investigate the dynamical properties of chaotic trajectories in mushroom billiards. These billiards present a well-defined simple border between a single regular region and a single chaotic component. We find that the stickiness of chaotic trajectories near the border of the regular region occurs through an infinite number of marginally unstable periodic orbits. These orbits have zero measur...

Closed analytical expressions for scattering intensity and other global structure factors are derived for a new solvable model of polydisperse sticky hard spheres. The starting point is the exact solution of the “mean spherical approximation” for hard core plus Yukawa potentials, in the limit of infinite amplitude and vanishing range of the attractive tail, with their product remaining constant...

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...

We developed and evaluated a device that can be used for the quantitative measurement of stickiness. While a typical pressure distribution sensor can measure a pressing force, it cannot measure a tensile force. We therefore installed a pin array on a sensor, with the pin array applying an offset pressure to the sensor through its weight. We measured the stickiness of natto and baby powder using...

To prevent users from switching to competitors, on-line companies in the B2C market are implementing various technologies and investing substantial resources to enhance the “stickiness” of their Web sites. The authors propose that users stick with a Web site through a process of developing a relationship with it. Thus, sticking with a Web site reflects a persistent Web site–user relationship. T...

Following a recession, the aggregate labor market is slack–employment remains below normal and recruiting efforts of employers, as measured by help-wanted advertising and vacancies, are low. A model of matching friction explains the qualitative responses of the labor market to adverse shocks, but requires implausibly large shocks to account for the magnitude of observed fluctuations. The incorp...
