Ages of young stars [PDF]

, 2013
Determining the sequence of events in the formation of stars and planetary systems and their time-scales is essential for understanding those processes, yet establishing ages is fundamentally difficult because we lack direct indicators. In this review we

Stellar ages from asteroseismology [PDF]

, 2008
Asteroseismology provides powerful means to probe stellar interiors. The oscillations frequencies are closely related to stellar interior properties via the density and sound speed profiles.

Whole Genome Sequencing Based Surveillance of L. monocytogenes for Early Detection and Investigations of Listeriosis Outbreaks

Frontiers in Public Health, 2019
In Austria, all laboratories are legally obligated to forward human and food/environmental L. monocytogenes isolates to the National Reference Laboratory/Center (NRL) for Listeria. Two invasive human isolates of L. monocytogenes serotype 1/2a of the same

Galaxies into the Dark Ages [PDF]

, 2017
We consider the capabilities of current and future large facilities operating at 2\,mm to 3\,mm wavelength to detect and image the [CII] 158\,$\mu$m line from galaxies into the cosmic "dark ages" ($z \sim 10$ to 20).

From Young and Hot to Old and Cold: Comparing White Dwarf Cooling Theory to Main Sequence Stellar Evolution in Open Clusters [PDF]

, 2005
I explore the current ability of both white dwarf cooling theory and main sequence stellar evolution theory to accurately determine stellar population ages by comparing ages derived using both techniques for open clusters ranging from 0.1 to 4 Gyr.

How Galaxies Disguise Their Ages [PDF]

, 2000
We calculate the contribution to Balmer line indices from far ultraviolet component sources. We find that this is significant, and may lead to identification of spurious age differences of the order of a total span of $\sim 6$ Gyrs or $\sim 15%$ size ...

Enrichment and analysis of glycated proteins

Reviews in Analytical Chemistry, 2022
Glycation is a spontaneous post-translational modification of lysine, arginine, and the N-terminus of proteins. Protein glycation is closely related to the pathogenesis of human diseases, including diabetes, Alzheimer’s disease, renal disease, and cancer.
