TL;DR: In this article, the ballistic treatment can be re-expressed in a diffusion limit such that conservation of lattice sites is retained and moreover, a closed-form steady-state solution exists.

TL;DR: An interferometric method to detect chemical binding at an interface that can be used to detect and quantify surface binding of less than 1 A of material, sensitivity similar to that of surface plasmon resonance imaging or arrayed imaging reflectometry.
Abstract: We report an interferometric method to detect chemical binding at an interface. The interference layer consists of the thin native oxide on silicon, and we utilize nearly opposite phase shifts of light at the oxide/water and oxide/silicon interfaces to achieve near-complete destructive interference. We measure selective binding of thrombin in solution to DNA aptamers covalently bound to the oxide. The technique can be used to detect and quantify surface binding of less than 1 A of material, sensitivity similar to that of surface plasmon resonance imaging or arrayed imaging reflectometry. Results are in quantitative agreement with what is predicted theoretically. The method is very convenient to implement since it utilizes unmodified silicon wafers as substrates and is extremely insensitive to both probe light bandwidth and collimation.

TL;DR: The data suggests that OBPs like AcerASP2 might make a large contribution toward assisting the honeybee in sensing and foraging flowers, and A. cerana has evolved a good circadian rhythm to perceive a flower's odor following the fluctuation of temperature in the olfactory system.

TL;DR: In this article, it was shown that β-scission selectivities increase with decreasing proton density, and that an equilibrated pool of reactive C6 ketols and alkenones are present at pseudo-steady-state concentrations during catalysis and that they act as intermediates in βscission routes.
