Blue light regulated shade avoidance
(Landes Bioscience, 2012-04)
Most plants grow in dense vegetation with the risk of being out-competed by neighboring plants. These neighbors can be detected not only through the depletion in light quantity that they cause, but also through the change ...
Rapid generation of HNO induced by visible light
(Royal Society of Chemistry, 2017-04)
We present a new method for controlled generation of HNO, based on the combination of a pH photoactuator induced by visible light with an HNO donor activated by pH increase. This method avoids the use of UV light, and in ...
Light intensity regulates stoichiometry of benthic grazers through changes in the quality of stream periphyton
(University of Chicago Press, 2019-06)
In mountain streams, light is a key factor for primary production and primary producer nutrient stoichiometry, or the relative composition of carbon (C) compared to phosphorous (P) and nitrogen (N) in primary producers. ...
Seasonal affective disorder: Lighting research and Environmental psychology
(Sage Publications Ltd, 2008-06)
This review uses Seasonal Affective Disorder, a depression with a seasonal pattern, to illustrate why engineers, architects, and designers need to look beyond their disciplines and make use of the research output of ...
Three-dimensional trapping of light with light in semiconductor planar microcavities
(American Physical Society, 2019-05)
When light is confined in all three directions and in dimensions of the order of the light wavelength, discretization of the photon spectra and distinctive phenomena occur, the Purcell effect and the inhibition of emission ...
Ultra-long light sheets via curved beam intercrossing
(Optical Society of America, 2020-07-31)
An approach to yield a planar light sheet with thickness below the Abbe’s diffraction limit over ultra-long propagation distances is presented. Such features emerge by an induced interference of the fields associated to ...
Twisted-light-induced optical transitions in semiconductors: Free-carrier quantum kinetics
(American Physical Society, 2010-09)
We theoretically investigate the interband transitions and quantum kinetics induced by light carrying orbital angular momentum, or twisted light, in bulk semiconductors. We pose the problem in terms of the Heisenberg ...
Electronic transitions in disk-shaped quantum dots induced by twisted light
(American Physical Society, 2009-04)
We theoretically investigate the absorption and emission of light carrying orbital angular momentum (twisted light) by quasi-two-dimensional (disk-shaped) quantum dots in the presence of a static magnetic field. We calculate ...
Procedure for continued urban lighting management evaluation
(Znack Publishing House, 2001-05)
In order to evaluate the urban lighting management, a procedure based on the benefit/cost operation relationship is described. Taking into account several types of facilities under different management and maintenance ...
Access to electric light is associated with shorter sleep duration in a traditionally hunter-gatherer community
(SAGE Publications, 2015-08)
Access to electric light might have shifted the ancestral timing and duration of human sleep. To test this hypothesis, we studied two communities of the historically hunter-gatherer indigenous Toba/Qom in the Argentinean ...
