Mapping Lightscapes: Spatial Patterning of Artificial Lighting in an Urban Landscape [PDF]

open access: yes, 2013
Artificial lighting is strongly associated with urbanisation and is increasing in its extent, brightness and spectral range. Changes in urban lighting have both positive and negative effects on city performance, yet little is known about how its ...

A study of discrete wavelet transform based denoising to reduce the effect of artificial light interferences for indoor optical wireless communication [PDF]

open access: yes, 2010
The optical power penalty (OPP) due to the artificial light interferences (ALIs) can be significantly high in an indoor optical wireless communication (OWC) channel making such link practically infeasible.

Wavelet—Artificial Neural Network Receiver for Indoor Optical Wireless Communications [PDF]

open access: yes, 2011
The multipath induced intersymbol interference (ISI) and fluorescent light interference (FLI) are the two most important system impairments that affect the performance of indoor optical wireless communication (OWC) systems.

Non-visual effects of light on human circadian physiology and neurobehavioral performance [PDF]

open access: yes, 2015
Light is of crucial importance for human circadian rhythms. In fact, light exposure allows for resetting individual biological rhythms to the 24-h day.

THE LINK BETWEEN CIRCADIAN CLOCK AND TUMORIGENESIS

open access: yesBuletinul Academiei de Ştiinţe a Moldovei: Ştiinţe Medicale, 2021
The circadian clock is fundamental for allowing the human body to work properly. Studies demonstrated that circadian disruption is a risk factor for a lot of pathological states and in this Review, the idea is to focus on tumorigenesis.

MCF-SCA: A Multi-Scale Spatio-Temporal Convolution and Multi-Order Gated Spatial-Channel Aggregation Networks for Cross-Subject EEG-Based Emotion Recognition

open access: yesInformation
Cross-subject emotion recognition using EEG remains challenging due to substantial inter-individual variability. To address this, we propose a Multi-scale Spatio-Temporal Convolution and Multi-order Gated Spatial-Channel Aggregation Network (MCF-SCA ...

Can artificial light promote submerged macrophyte growth in summer?

open access: yes, 2021
Loss of submerged macrophytes resulting from high turbidity has become a global environmental problem in shallow lakes, associated with eutrophication. To help macrophyte recovery, application of artificial light-emitting diodes (LEDs) has been proposed ...
