Title Direct and indirect effects of light pollution on the performance of an herbivorous insect Type Journal Article
Year 2018 Publication Insect Science Abbreviated Journal (up) Insect Sci
Volume 26 Issue 4 Pages 770-776
Keywords Animals; Plants
Abstract Light pollution is a global disturbance with resounding impacts on a wide variety of organisms, but our understanding of these impacts is restricted to relatively few higher vertebrate species. We tested the direct effects of light pollution on herbivore performance as well as indirect effects mediated by host plant quality. We found that artificial light from streetlights alters plant toughness. Additionally, we found evidence of both direct and indirect effects of light pollution on the performance of an herbivorous insect, which indicates that streetlights can have cascading impacts on multiple trophic levels. Our novel findings suggest that light pollution can alter plant-insect interactions and thus may have important community-wide consequences.

Title The Acute Effects of Intermittent Light Exposure in the Evening on Alertness and Subsequent Sleep Architecture Type Journal Article
Year 2018 Publication International Journal of Environmental Research and Public Health Abbreviated Journal (up) Int J Environ Res Public Health
Volume 15 Issue 3 Pages
Keywords Human Health
Abstract Exposure to bright light is typically intermittent in our daily life. However, the acute effects of intermittent light on alertness and sleep have seldom been explored. To investigate this issue, we employed within-subject design and compared the effects of three light conditions: intermittent bright light (30-min pulse of blue-enriched bright light (~1000 lux, ~6000 K) alternating with 30-min dim normal light (~5 lux, ~3600 K) three times); continuous bright light; and continuous dim light on subjective and objective alertness and subsequent sleep structure. Each light exposure was conducted during the three hours before bedtime. Fifteen healthy volunteers (20 +/- 3.4 years; seven males) were scheduled to stay in the sleep laboratory for four separated nights (one for adaptation and the others for the light exposures) with a period of at least one week between nights. The results showed that when compared with dim light, both intermittent light and continuous bright light significantly increased subjective alertness and decreased sleep efficiency (SE) and total sleep time (TST). Intermittent light significantly increased objective alertness than dim light did during the second half of the light-exposure period. Our results suggested that intermittent light was as effective as continuous bright light in their acute effects in enhancing subjective and objective alertness and in negatively impacting subsequent sleep.

Title A Global Perspective for Sustainable Highway Tunnel Lighting Regulations: Greater Road Safety with a Lower Environmental Impact Type Journal Article
Year 2018 Publication International Journal of Environmental Research and Public Health Abbreviated Journal (up) Int J Environ Res Public Health
Volume 15 Issue 12 Pages
Keywords Lighting
Abstract Tunnel lighting installations function 24 h a day, 365 days a year. These infrastructures have increased exponentially and now connect quite distant locations, even on different continents. This has led European administrations and international regulatory bodies to establish regulations for tunnel safety with the lowest environmental impact. However, until now, these regulations have almost exclusively focused on traffic safety, and relegated sustainability to the background. Even though they recognize the need to reduce energy consumption, they do not propose any tools for doing so. Given the impact of these installations and the lack of a specific regulatory framework, Asian countries will soon be forced either to update previous standards for tunnel lighting or elaborate new ones. A better understanding of the weaknesses of European regulations combined with a willingness to embrace innovation could position Asia as a world leader in the regulation of more sustainable road tunnels. The objective of this research was to improve the sustainability of tunnel lighting installations through new regulations or amendments to existing ones, without impairing the mental well-being of users, who could potentially be affected by energy-saving measures. Accordingly, this paper presents and analyzes a broad proposal for formulating tunnel lighting regulations. The originality of this proposal lies in the fact that it integrates road safety, lower environmental impact, and user well-being. Furthermore, it is expected to broaden the perspective of regulatory bodies and public administrations with regard to tunnel installations, which would ultimately enhance their sustainability.

Title Regulation of the MAPK signaling pathway by miR-421-5p in rats under light pollution Type Journal Article
Year 2018 Publication International Journal of Molecular Medicine Abbreviated Journal (up) Int J Mol Med
Volume in press Issue Pages in press
Keywords Animals
Abstract The present study aimed to explore the difference in the expression profiles of ovarian microRNA sequences in rats in a light pollution environment and rats in a normal light environment. Rats in the control group were exposed to 12h light/dark cycles, while rats in the model group were continuously exposed to 24h light. The ovaries were extracted from the two groups of rats, and Illumina HiSeq 2500 highthroughput sequencing technology was used to detect the differences in microRNA (miRNA) expression among the two groups. Fluorescence quantitative reverse transcriptionpolymerase chain reaction was used to verify the differential expression of miRNA. The present study was designed to experimentally validate the interaction between miR4215p and mitogenactivated protein kinase (MAPK) 7 by using the dualluciferase reporter system, and to explore the expression of proteins in the MAPK signaling pathway with a lentiviral vectormediated small hairpin RNA interference against microRNA4215p. The expression of 45 miRNAs was significantly different. In total, 13 miRNAs were upregulated, of which 5 miRNA sequences were known and 8 were predicted. Furthermore, 32 miRNAs were downregulated, of which 11 miRNA sequences were known and 21 were predicted. The results of the luciferase reporter assay confirmed the targeting association between miR4215p and MAPK7. The expression levels of MAPK and genes in its downstream signaling pathways, including cFos, CREB and cMyc, were downregulated when miR4215p was overexpressed and upregulated when miR4215p was silenced. The differential expression of miRNAs may serve an important role in the development of the ovary in a light pollution environment. miR4215p may regulate ovarian growth and development by targeting the MAPK signaling pathway in light polluted rat ovaries.

Title Application of power line communication technology in street lighting control Type Journal Article
Year 2018 Publication International Journal of Design & Nature and Ecodynamics Abbreviated Journal (up) Int. J. DNE
Volume 13 Issue 2 Pages 176-186
Keywords Lighting
Abstract Rapidly increasing usage of telecommunication systems causes new transmission technologies and networks to emerge. Not only the efficiency, reliability and accessibility of the network are important, but also the economic issues. One cost-effective solution could be power line communication (PLC) technology, which transmits data using the existing electricity infrastructure. The application of this communication technique is an attractive and innovative solution for the realization of smart cities and smart homes. With intelligent control networks, energy savings can be optimized and the operating as well as maintenance costs can be reduced. Since outdoor lighting systems are the major consumers of electricity, to create a modern, energy-efficient city, intelligent street lighting control is needed. This paper provides an overview of power line communication principles including the theoretical background of data communication, modulation techniques, channel access methods, protocols, disturbances and noises. Furthermore, in order to highlight the benefits of a PLC-based street lighting control system, a pilot project will be presented.
