Time and frequency transfer in all-optical network
Smotlacha, V. ; Kuna, Alexander
This paper describes usage of all-optical network for time metrology application - Time and frequency transfer between two geographically distant sites. Although several approaches exist, there is no production implementation yet. Our method is based on newly developed adapters utilizing channels in a DWDM (Dense Wavelength-Division Multiplexing) network. We present results of tests performed in real production all-optical network including the time transfer between atomic clocks in Prague and Vienna over more than 500 km long optical path

Emmer, J. ; Vavrinská, A. ; Sychrovský, Vladimír ; Benda, Ladislav ; Kříž, Z. ; Koča, J. ; Boelens, R. ; Sklenář, V. ; Trantírek, L.
Density functional theory was employed to study the influence of O-phosphorylation of serine, threonine, and tyrosine on the amidic N-15 chemical shielding anisotropy (CSA) tensor in the context of the complex chemical environments of protein structures.
