Impact of optical crosstalk in fibre-radio systems incorporating WDM

open access: yes, 2003
We investigate analytically and experimentally optical crosstalk effects in fibre-radio, systems incorporating wavelength-division multiplexing. Both in-band and out-of-band crosstalk are considered and the effect of the RF phase difference between the ...

An Adipocyte MKK3–p38β Axis Preserves Insulin Responsiveness in Mice and Is Reciprocally Altered in Human Obesity

open access: yesAdvanced Science, EarlyView.
The adipocyte MKK3–p38β axis emerges as an adaptive stress‐response pathway during obesity. Human visceral adipose tissue analyses, adipocyte‐specific mouse models, and primary adipocytes show that the MKK3–p38β axis supports insulin responsiveness by restraining p70S6K‐dependent inhibitory IRS1 feedback and preserving AKT–GLUT4 signaling. This pathway
