Nature research paper: Diode effect in Josephson junctions with a single magnetic atom
from the slope of thecurve in the trapped state. In analysing the data, we account for several instrumental effects. A slow creep of the piezoelectric elements causes the tip to drift towards the surface, effectively changing the junction conductance. We continuously monitor. The differential amplifier used during the Josephson measurements introduces a slowly shifting voltage offset, which we subtract from the individualcurves. The voltage/current source has a small offset.

Multicopy suppressor screens reveal convergent evolution of single-gene lysis proteins - Nature Chemical BiologyIn contrast to dsDNA phages where multiple genes are involved in programmed host lysis, ssRNA Fiersviridae phages require only a single gene. Here, genome-wide host suppressors of diverse single-gene lysis systems are identified using a high-throughput genetic screen.
