In vitro relationships of galactic cosmic radiation and epigenetic clocks in human bronchial epithelial cells

open access: yesEnvironmental and Molecular Mutagenesis, Volume 63, Issue 4, Page 184-189, April 2022., 2022
Abstract Ionizing radiation is a well‐appreciated health risk, precipitant of DNA damage, and contributor to DNA methylation variability. Nevertheless, relationships of ionizing radiation with DNA methylation‐based markers of biological age (i.e. epigenetic clocks) remain poorly understood.

A Platform for Complementary Metal‐Oxide‐Semiconductor Compatible Plasmonics: High Plasmonic Quality Titanium Nitride Thin Films on Si (001) with a MgO Interlayer

open access: yesAdvanced Photonics Research, Volume 2, Issue 7, July 2021., 2021
The insertion of a thin MgO interlayer for TiN on Si (001) leads to cube‐on‐cube epitaxy of TiN films on Si with significantly improved plasmonic quality. The TiN/MgO/Si structure enables access to the hybrid‐plasmonic‐photonic waveguide platform with sufficiently low losses, and thus long propagation lengths from microns to tens of micrometers, for ...

180 Gbit/s 4:1 power multiplexer for NRZ‐OOK signals with high output voltage swing in SiGe BiCMOS technology

open access: yesElectronics Letters, Volume 56, Issue 2, Page 69-71, January 2020., 2020
A 4:1 multiplexer (MUX) circuit in SiGe BiCMOS technology intended to directly drive a plasmonic Mach–Zehnder modulator for transmitter applications is presented. To achieve the highest data rates at a high output voltage swing, a power MUX concept is applied that maps the high‐speed performance of the final clock signal onto the output data.
