Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Applications of the optical fiber to the generation and to the measurement of low-phase-noise microwave signals

, 2008
The optical fiber used as a microwave delay line exhibits high stability and low noise and makes accessible a long delay (>100 microseconds) in a wide bandwidth (about 40 GHz, limited by the optronic components).

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]

, 2002
This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume

Stimulated Raman Spectroscopic Imaging by Microsecond Delay-Line Tuning

Asia Communications and Photonics conference and Exhibition, 2016
We report microsecond-scale acquisition of simulated Raman spectra by resonant delay-line tuning. Our scheme improved the spectral acquisition speed by 100 times compared to previous works by motorized translational-stage tuning. 4-D images ($\mathrm{x}-\

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Gigahertz optical tuning of an on-chip radio frequency photonic delay line

, 2017
Rapid and continuous tunability of time delay is a crucial functionality for radio frequency (RF) photonic signal processing systems. Recent developments in photonic integration have enabled realizations of integrated microwave photonic (MWP) delay lines

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.
