On the Accuracy of Infrared Photometry [PDF]

open access: yesSymposium - International Astronomical Union, 1985
Photometric errors due to scintillation are considered in detail. Given noise characteristics, the standard deviations, as deduced from observations, are computed for the quantities measured at successive steps of the photometric procedure. This allows us to understand better the errors computed on-line in observatories, and to understand better the ...

Photometric and Spectral Characterization of Spacecraft Materials With Application to Lunar Trailblazer

open access: yesEarth and Space Science, Volume 13, Issue 3, -Not available-.
Abstract If a spacecraft loses contact with Earth, ground‐based observatories can collect observations to assist the recovery effort by providing information on spacecraft location and state. Optical observations converted to a light curve of spacecraft magnitude over time show the spin period and/or orientation of the spacecraft.

Structural basis for uPAR binding to an antibody developed for targeted cancer therapy. Mechanistic insights into flexibility, ligand recognition, and molecular imaging

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract The urokinase‐type plasminogen activator receptor (uPAR) is currently gaining momentum as a promising molecular target for treatment of various solid cancers. For patient stratification, we developed a high‐affinity uPAR‐targeting peptide (AE105) detecting primary cancer lesions as well as occult metastasis by positron emission tomography (PET)

Inhibiting Liver‐Derived C3 Protein Rescues Anesthesia/Surgery‐Induced Cognitive Impairment, Synaptic Disorders, and Microglial Phagocytosis

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
This study provides evidence that anesthesia/surgery can induce the BBB breakdown and promote the release of hepatogenous C3 protein into the blood. This surgical dual factors ultimately drove C3 to cross the damaged BBB and selectively colocalize with C3aR in the hippocampus, which results in structural and functional injury of synapse, C3aR‐mediated ...

Exploration of the Near-infrared Colors of Cold Y Dwarfs from the Ground and Space

open access: yesThe Astrophysical Journal
The James Webb Space Telescope (JWST) has provided critical mid-infrared data for cold brown dwarfs. It has also provided low-resolution near-infrared spectra, and for faint sources these are the first spectra at these wavelengths.
