High Speed Visible Light Communication Using Blue GaN Laser Diodes [PDF]

, 2016
GaN-based laser diodes have been developed over the last 20 years making them desirable for many security and defence applications, in particular, free space laser communications.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Daily blue-light exposure shortens lifespan and causes brain neurodegeneration in Drosophila

npj Aging and Mechanisms of Disease, 2019
Light is necessary for life, but prolonged exposure to artificial light is a matter of increasing health concern. Humans are exposed to increased amounts of light in the blue spectrum produced by light-emitting diodes (LEDs), which can interfere with ...

Effects of blue pulsed light on human physiological functions and subjective evaluation

Journal of Physiological Anthropology, 2012
Background It has been assumed that light with a higher irradiance of pulsed blue light has a much greater influence than that of light with a lower irradiance of steady blue light, although they have the same multiplication value of irradiance and ...

Effect of Photoperiod on Chinese Kale (Brassica alboglabra) Sprouts Under White or Combined Red and Blue Light

Frontiers in Plant Science, 2021
To determine the response of Chinese kale (Brassica alboglabra) sprouts to photoperiods under different light sources, we used four photoperiods (0-h light/24-h dark, 8-h light/16-h dark, 12-h light/12-h dark, and 16-h light/8-h dark) to investigate ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Genome-wide analyses of light-regulated genes in Aspergillus nidulans reveal a complex interplay between different photoreceptors and novel photoreceptor functions.

PLoS Genetics, 2021
Fungi sense light of different wavelengths using blue-, green-, and red-light photoreceptors. Blue light sensing requires the "white-collar" proteins with flavin as chromophore, and red light is sensed through phytochrome.

Blue-light induced infrared absorption in KNbO3 [PDF]

, 1994
We have used a high-finesse cavity to measure the cw intensity dependence and dynamics of blue-light-induced infrared absorption (BLIIRA) in KNbO3 crystals for blue-light intensities between 7 x 10^-4 and 2 x 10^4 W/cm^2.

75%-efficiency blue generation from an intracavity PPKTP frequency doubler [PDF]

, 2004
We report on a high-efficiency 461 nm blue light conversion from an external cavity-enhanced second-harmonic generation of a 922 nm diode laser with a quasi-phase-matched KTP crystal (PPKTP).

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
