Atomic clock ensemble in space (ACES) data analysis [PDF]
, 2017 The Atomic Clocks Ensemble in Space (ACES/PHARAO mission, ESA & CNES) will be installed on board the International Space Station (ISS) next year. A crucial part of this experiment is its two-way microwave link (MWL), which will compare the timescale ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Shell-structure effects on high-pressure Rankine-Hugoniot shock adiabats
, 2007 Rankine-Hugoniot shock adiabats are calculated in the pressure range 1 Mbar-10 Gbar with two atomic-structure models: the atom in a spherical cell and the atom in a jellium of charges.

Benchmarking atomic data for astrophysics: a first look at the soft X-ray lines [PDF]
, 2012 A collection of the best solar and laboratory spectra in the soft X-rays is used here to perform a preliminary benchmark in this wavelength region, by comparing observed vs. predicted wavelengths and calibrated solar irradiances. The benchmark focuses on

ATOMIC and Molecular Data [PDF]
Symposium - International Astronomical Union, 1978 Excitation, ionization and recombination processes are discussed elsewhere in this volume by Seaton (1977). I will restrict my attention to those processes involving heavy particles that may modify the ionization structure of planetary nebulae and that may affect the molecular composition of condensations and of the transition regions between the ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...
