Atmospheric Light Columns from Artificial Lights [PDF]

Nature, 1930
WHEN travelling by tram, I have often seen the light of street lamps drawn out into beams perpendicular to the direction of streaks left upon the window glass. Effective fibres of the cleaners' cloth are sensibly parallel, and though I had mentally noted that the beams were due to diffraction, it had not hitherto seemed worth while publishing the ...

A light-driven artificial flytrap [PDF]

Nature Communications, 2017
AbstractThe sophistication, complexity and intelligence of biological systems is a continuous source of inspiration for mankind. Mimicking the natural intelligence to devise tiny systems that are capable of self-regulated, autonomous action to, for example, distinguish different targets, remains among the grand challenges in biomimetic micro-robotics ...

Analysis on the Economic Feasibility of a Plant Factory Combined with Architectural Technology for Energy Performance Improvement

Agriculture, 2022
In this study, a comparative economic analysis was conducted for typical greenhouses, plant factories with natural and artificial light, and those with only artificial light, based on the insulation, artificial light, and photovoltaic (PV) installation ...

USE OF ARTIFICIAL LIGHT IN MUSHROOM CULTIVATION [PDF]

Biotechnologia Acta, 2013
Artificial light is used in greenhouses to increase productivity and quality of agricultural and ornamental plants. Despite the awareness of the fact that light also plays important role in the life of nonhotosynthetic organisms, such as fungi, its using

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

Information
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 ...

SDENet: A Novel Approach for Single Image Depth of Field Extension

Algorithms
Traditional hardware-based approaches for depth-of-field extension (DOF-E), such as optimized lens design or focus-stacking via layer scanning, are often plagued by bulkiness and prohibitive costs.

Light pollution affects the coastal zone of Lake Baikal

Limnological Review, 2021
The role of light pollution in aquatic ecosystems functioning has increased in recent times. In addition, the effect of such pollution has mostly been studied in coastal marine ecosystems, leaving freshwater ecosystems much less studied.

Generating artificial light curves: Revisited and updated

, 2013
The production of artificial light curves with known statistical and variability properties is of great importance in astrophysics. Consolidating the confidence levels during cross-correlation studies, understanding the artefacts induced by sampling ...
