The Low Noise Limit in Gene Expression. [PDF]
PLoS ONE, 2015 Protein noise measurements are increasingly used to elucidate biophysical parameters. Unfortunately noise analyses are often at odds with directly measured parameters. Here we show that these inconsistencies arise from two problematic analytical choices:

Low-noise GaAs quantum dots for quantum photonics [PDF]
Nature Communications, 2020 Quantum dots are both excellent single-photon sources and hosts for single spins. This combination enables the deterministic generation of Raman-photons—bandwidth-matched to an atomic quantum-memory—and the generation of photon cluster states, a resource

Low-Frequency Noise: Experiences from a Low-Frequency Noise Perceiving Population
International Journal of Environmental Research and Public Health, 2023 Although low-frequency noise (LFN) is associated with various complaints, there is still much unknown about this phenomenon. This research aims to provide an extensive description of (1) LFN perceptions, (2) LFN-related complaints, and (3) the characteristics of LFN complainants. In an explorative observational cross-sectional survey study, a sample of
