Title MOBILE MAPPING OF NIGHT-TIME ROAD ENVIRONMENT LIGHTING CONDITIONS Type Journal Article
Year 2018 Publication The Photogrammetric Journal of Finland Abbreviated Journal
Volume (down) 26 Issue 1 Pages
Keywords Lighting; Remote Sensing
Abstract The measurement of 3D geometry for road environments is one of the main applications of mobile mapping systems (MMS). We present mobile mapping applied to a night-time road environment. We integrate the measurement of luminances into a georeferenced 3D point cloud. The luminance measurement and the 3D point cloud acquired with an MMS are used in assessing road environment lighting conditions. Luminance (cd/m2) was measured with a luminance-calibrated panoramic camera system, and point cloud was produced by laser scanners. The relative orientation between the GNSS, IMU, camera, and laser scanner sensors was solved in order to

integrate the data sets into the same coordinate system. Hence, the georeferenced luminance values are transferable into geographic information systems (GIS). The method provides promising results for future road lighting assessment. In addition, this article demonstrates the night-time mobile mapping principle applied to a road section in Helsinki, Finland. Finally, we discuss the

future applications of mobile-mapped luminance point clouds.

Title Artificial Light at Night of Different Spectral Compositions Differentially Affects Tumor Growth in Mice: Interaction With Melatonin and Epigenetic Pathways Type Journal Article
Year 2018 Publication Cancer Control : Journal of the Moffitt Cancer Center Abbreviated Journal Cancer Control
Volume (down) 25 Issue 1 Pages 1073274818812908
Keywords Human Health; 6-Smt; Cfl; EE-halogen; GDM-levels; body mass; carbon; corticosterone; cosinor analysis; light at night; yellow-LED
Abstract Lighting technology is rapidly advancing toward shorter wavelength illuminations that offer energy-efficient properties. Along with this advantage, the increased use of such illuminations also poses some health challenges, particularly breast cancer progression. Here, we evaluated the effects of artificial light at night (ALAN) of 4 different spectral compositions (500-595 nm) at 350 Lux on melatonin suppression by measuring its urine metabolite 6-sulfatoxymelatonin, global DNA methylation, tumor growth, metastases formation, and urinary corticosterone levels in 4T1 breast cancer cell-inoculated female BALB/c mice. The results revealed an inverse dose-dependent relationship between wavelength and melatonin suppression. Short wavelength increased tumor growth, promoted lung metastases formation, and advanced DNA hypomethylation, while long wavelength lessened these effects. Melatonin treatment counteracted these effects and resulted in reduced cancer burden. The wavelength suppression threshold for melatonin-induced tumor growth was 500 nm. These results suggest that short wavelength increases cancer burden by inducing aberrant DNA methylation mediated by the suppression of melatonin. Additionally, melatonin suppression and global DNA methylation are suggested as promising biomarkers for early diagnosis and therapy of breast cancer. Finally, ALAN may manifest other physiological responses such as stress responses that may challenge the survival fitness of the animal under natural environments.

Title Blue light exposure decreases systolic blood pressure, arterial stiffness, and improves endothelial function in humans Type Journal Article
Year 2018 Publication European Journal of Preventive Cardiology Abbreviated Journal Eur J Prev Cardiol
Volume (down) 25 Issue 17 Pages 1875-1883
Keywords Human Health; Blue light; blood pressure; endothelial function; forearm blood flow; pulse wave velocity
Abstract AIMS: Previous studies have shown that ultraviolet light can lead to the release of nitric oxide from the skin and decrease blood pressure. In contrast to visible light the local application of ultraviolet light bears a cancerogenic risk. Here, we investigated whether whole body exposure to visible blue light can also decrease blood pressure and increase endothelial function in healthy subjects. METHODS: In a randomised crossover study, 14 healthy male subjects were exposed on 2 days to monochromatic blue light or blue light with a filter foil (control light) over 30 minutes. We measured blood pressure (primary endpoint), heart rate, forearm vascular resistance, forearm blood flow, endothelial function (flow-mediated dilation), pulse wave velocity and plasma nitric oxide species, nitrite and nitroso compounds (secondary endpoints) during and up to 2 hours after exposure. RESULTS: Blue light exposure significantly decreased systolic blood pressure and increased heart rate as compared to control. In parallel, blue light significantly increased forearm blood flow, flow-mediated dilation, circulating nitric oxide species and nitroso compounds while it decreased forearm vascular resistance and pulse wave velocity. CONCLUSION: Whole body irradiation with visible blue light at real world doses improves blood pressure, endothelial function and arterial stiffness by nitric oxide released from photolabile intracutanous nitric oxide metabolites into circulating blood.

Title Illuminating austerity: Lighting poverty as an agent and signifier of the Greek crisis Type Journal Article
Year 2018 Publication European Urban and Regional Studies Abbreviated Journal Eur Urban Reg Stud
Volume (down) 25 Issue 4 Pages 360-372
Keywords Economics; Society
Abstract Light – whether natural or artificial – plays multiple roles in the home: both as a material enabler of everyday life and as a device for exercising a variety of social relations. The post-2008 Greek economic crisis has endangered those roles by limiting people's ability to access or afford adequate energy services. This paper focuses on the enforced lack of illumination in the home, and the strategies and tactics undertaken by households to overcome this challenge. I connect illumination practices and discourses to the implementation of austerity, by arguing that the threat of darkness has become a tool for compelling vulnerable groups to pay their electricity bills. The evidence presented in the paper is based on two sets of interviews with 25 households (including a total of 55 adult members) living in and around Thessaloniki – Greece's second largest city, and one that has suffered severe economic consequences as a result of the crisis. I have established that the under-consumption of light is one of the most pronounced expressions of energy poverty, and as such endangers the ability to participate in the customs that define membership of society. But the emergence of activist-led amateur electricians and the symbolic and material mobilization of light for political purposes have also created multiple opportunities for resistance.

Title Impact of artificial lighting on capture success in two species of frugivorous bats (chiroptera: phyllostomidae) in an urban locality from the Venezuelan Andes Type Journal Article
Year 2018 Publication Mastozoologia Neotropical Abbreviated Journal
Volume (down) 25 Issue 2 Pages
Keywords Animals
Abstract Artificial light is becoming a major issue for bats because it affects critical activities such as foraging, reproduction, and communication. We assessed the effect of artificial lighting on Artibeus lituratus and Artibeus jamaicensis in a small secondary growth forest patch near a street subjected to unexpected illumination. Bats were captured in the forest patch using a 12-m long mist net. Results indicated a nearly six-fold, significant decrease in capture success after the street lamps were installed. Artificial light from street lamps functions as a “light barrier” that inhibits bats from conducting short and long-distance movements, which might have detrimental consequences for bats and the plants they disperse. RESUMEN. Impacto de la luz artificial en el éxito de captura de dos especies de murciélagos frugívoros (Chiroptera: Phyllostomidae) en una localidad urbana de Los Andes venezolanos. La luz artificial se ha convertido en un problema grave para los murciélagos, porque está afectando actividades críticas que incluyen forrajeo, reproducción y comunicación. Evaluamos el efecto de la luz artificial en los murciélagos frugívoros Artibeus lituratus y Artibeus jamaicensis, en un pequeño parche de bosque secundario, cercano a una calle sujeta a una iluminación artificial inesperada. Capturamos a los murciélagos en el bosque secundario, empleando una red de neblina de 12 m de longitud. Los resultados indican que el éxito de captura disminuyó significativamente casi seis veces después de la instalación de los bombillos. La luz artificial de las lámparas funciona como “barreras u obstáculos de luz” que inhiben a los murciélagos de realizar movimientos de corta y larga distancia, lo cual podría tener consecuencias perjudiciales para los murciélagos y las plantas que ellos dispersan.
