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 ...

Output Power Monitoring of Ultraviolet Light-Emitting Diode via Sapphire Substrate

Photonics, 2020
Ultraviolet (UV) light plays an important role in air/water/surface sterilization now. Maintaining a certain light intensity is often required to attain the targeted effect. In this paper, on-chip power monitoring of a UV-A light-emitting diode (LED) via

Closed loop fiber optic rotation sensor [PDF]

, 1987
An improved optical gyroscope is provided, of the type that passes two light components in opposite directions through an optic fiber coil, and which adds a small variable frequency to one of the light components to cancel the phase shift due to rotation

High output LED in hybrid lighting for Alstroemeria

Acta Horticulturae, 2022
Alstroemeria cultivation in the Netherlands requires artificial light in order to overcome the low levels of natural light in winter. Typical supplementary light levels are low (60-100 µmol m-2 s-1). In order to increase the supplementary light intensity with the lowest possible electricity costs, Alstroemeria producers are placing LED lights as an ...

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 ...

Effects of Neutron Irradiations in Various Crystal Samples of Large Size for Future Crystal Calorimeter [PDF]

, 2010
In this paper, we report an investigation on the radiation damage effects induced by neutrons in large size crystal scintillator: BGO, CeF_3, LYSO:Ce and PWO. The irradiations were carried out by using fast neutrons from one ^(241)Am-Be and two ^(252)

Enhanced light output of dipole source in GaN-based nanorod light-emitting diodes by silver localized surface plasmon

, 2014
The light output of dipole source in three types of light-emitting diodes (LEDs), including the conventional planar LED, the nanorod LED, and the localized surface plasmon (LSP) assisted LED by inserting silver nanoparticles in the gaps between nanorods,

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
