INTEGRAL Cross-calibration Status

open access: yes, 2004
The status of the INTEGRAL cross-calibration is presented for a standard X-ray astronomy source, the Crab Nebula, as well as for some weaker sources. The relative flux normalization for the different INTEGRAL instruments is discussed together with spectral shape features.

Radiometric Cross-calibration of KOMPSAT-3A with Landsat-8 [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
In this study, Cross calibration was conducted at the Libya 4 PICS site on 2015 using Landsat-8 and KOMPSAT-3A. Ideally a cross calibration should be calculated for each individual scene pair because on any given date the TOA spectral profile is ...

Initial Cross-Calibration of Landsat 8 and Landsat 9 Using the Simultaneous Underfly Event

open access: yesRemote Sensing, 2022
With the launch of Landsat 9 in September 2021, an optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while being moved into its final orbit.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
