A Review of Slow- and Fast-Light Based on Stimulated Brillouin Scattering in Future Optical Communication Networks

open access: yesCommunications, 2008
Slow- and Fast-Light has been investigated during the last years as a powerful tool to reduce and increase the group velocity of light pulses by light.

Privatisierung der Infrastruktur und Raumordnungspolitik [PDF]

open access: yesGeographica Helvetica
Die Globalisierung und der internationale Standortwettbewerb haben in den letzten Jahren auch in der Schweiz eine eigentliche Liberalisierungs-, Privatisierungs- und Deregulierungswelle ausgelöst.

Ursachen und Folgen des Telekommunikationsnotstandes in den neuen Bundesländern

open access: yesRaumforschung und Raumordnung, 1991
Aufgrund jahrzehntelanger Vernachlässigung der Fernmeldeinfrastruktur stehen im Osten Deutschlands die uns im Westen zur Selbstverständlichkeit gewordenen Möglichkeiten der Telekommunikation nicht oder nur in höchst unzureichender Weise zur Verfügung ...

Coherent $$\mathrm{J}/\psi $$ J / ψ  and $${\uppsi '}$$ ψ ′  photoproduction at midrapidity in ultra-peripheral Pb–Pb  collisions at $$\sqrt{s_{\mathrm {NN}}}~=~5.02$$ s NN = 5.02  TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The coherent photoproduction of $$\mathrm{J}/\psi $$ J / ψ and $${\uppsi '}$$ ψ ′ mesons was measured in ultra-peripheral Pb–Pb collisions at a center-of-mass energy $$\sqrt{s_{\mathrm {NN}}}~=~5.02$$ s NN = 5.02  TeV  with the ALICE detector.

Flexible Nyquist Pulse Sequence Generation With Variable Bandwidth and Repetition Rate

open access: yesIEEE Photonics Journal, 2014
The rectangular spectrum of sinc-shaped Nyquist pulses enables the encoding of data in a minimum spectral width. Sinc pulses can improve optical sampling devices, could enable the implementation of ideal rectangular microwave photonics filters, and can ...

Measurement of beauty and charm production in pp collisions at s $$ \sqrt{s} $$ = 5.02 TeV via non-prompt and prompt D mesons

open access: yesJournal of High Energy Physics, 2021
The p T-differential production cross sections of prompt and non-prompt (produced in beauty-hadron decays) D mesons were measured by the ALICE experiment at midrapidity (| y | < 0.5) in proton-proton collisions at s $$ \sqrt{s} $$ = 5.02 TeV.
