  Title Correlation Analysis of Image Reproduction and Display Color Temperature Change to Prevent Sleep Disorder Type Journal Article
  Year 2019 Publication IEEE Access Abbreviated Journal IEEE Access  
  Volume 7 Issue Pages (down) 59091-59099  
  Keywords Human Health  
  Abstract This paper aims to determine the effect of the smartphone warm color temperature functionthat relieves display’s HEVL (high-energy visible light and short wavelength series blue light), which isknown to cause suppression of melatonin secretion on actual image reproduction quality. For this study,the author of this paper measured the display based on the color difference in 26 sampling colors. It was foundthat for correlated color temperature (CCT) of 4000 K or less, the color difference rose sharply, centeringaround red and green. In hardware or software, a low CCT was realized by reducing the output centered onblue and green, but in actual color quality, a problem arose in the red and green channels. As far as tonegradation is concerned,1E increased for CCT of 4500 K or less while the accuracy of the shadow detail wasreduced. With regard to color gamut reproduction, for the coverage of sRGB color space, the color gamutbecame narrow for CCT of 5500 K or less, and for volume, the color gamut became narrow sharply for CCTof 4000 K. It was found that the maximum CCT changes to prevent a decline in melatonin secretion at alevel of minimizing the degradation of image quality is 4000–4500 K.

  Title Light-at-night exposure affects brain development through pineal allopregnanolone-dependent mechanisms Type Journal Article
  Year 2019 Publication ELife Abbreviated Journal Elife  
  Volume 8 Issue Pages (down) e45306  
  Keywords Animals; chicken; neuroscience; Circadian disruption; pineal allopregnanolone; cell death  
  Abstract The molecular mechanisms by which environmental light conditions affect cerebellar development are incompletely understood. We showed that circadian disruption by light-at-night induced Purkinje cell death through pineal allopregnanolone (ALLO) activity during early life in chicks. Light-at-night caused the loss of diurnal variation of pineal ALLO synthesis during early life and led to cerebellar Purkinje cell death, which was suppressed by a daily injection of ALLO. The loss of diurnal variation of pineal ALLO synthesis induced not only reduction in pituitary adenylate cyclase-activating polypeptide (PACAP), a neuroprotective hormone, but also transcriptional repression of the cerebellar Adcyap1 gene that produces PACAP, with subsequent Purkinje cell death. Taken together, pineal ALLO mediated the effect of light on early cerebellar development in chicks.

  Title Amazon Fire Monitoring and Analysis Based on Multi-source Remote Sensing Data Type Journal Article
  Year 2020 Publication IOP Conference Series: Earth and Environmental Science Abbreviated Journal IOP Conf. Ser.: Earth Environ. Sci.  
  Volume 474 Issue Pages (down) 042025  
  Keywords Remote Sensing  
  Abstract In August 2019, a large-scale fire broke out in the Amazon rainforest, bringing serious harm to the ecosystem and human beings. In order to accurately monitor the dynamic change of forest fire in Amazon rainforest and analyse the impact of fire spreading and extinction on the environment, firstly, based on NPP VIIRS data covering the Amazon fire area, the sliding window threshold method is adopted to extract the fire point, and the cause of fire change is monitored and analysed according to the time series. Secondly, based on the time series of CALIPSO data, the vertical distribution changes of atmospheric pollutants in the amazon fire area are analysed, and the comprehensive analysis is carried out by combining NPP VIIRS data. The experimental results show that only NPP VIIRS data is used to predict the fire, and the combination of CALIPSO data can better monitor the forest fire and predict the fire development trend. The combination of optical image and laser radar has greater advantages in dynamic fire monitoring and fire impact analysis. The method described in this paper can provide basic data reference for real-time and accurate prediction of forest fires and provide new ideas for dynamic fire monitoring.

  Title Acute exposure to low-level light at night is sufficient to induce neurological changes and depressive-like behavior Type Journal Article
  Year 2019 Publication Molecular Psychiatry Abbreviated Journal Mol Psychiatry  
  Volume Issue Pages (down) s41380-019-0430-4  
  Keywords Human health; physiology; brain  
  Abstract The advent and wide-spread adoption of electric lighting over the past century has profoundly affected the circadian organization of physiology and behavior for many individuals in industrialized nations; electric lighting in homes, work environments, and public areas have extended daytime activities into the evening, thus, increasing night-time exposure to light. Although initially assumed to be innocuous, chronic exposure to light at night (LAN) is now associated with increased incidence of cancer, metabolic disorders, and affective problems in humans. However, little is known about potential acute effects of LAN. To determine whether acute exposure to low-level LAN alters brain function, adult male, and female mice were housed in either light days and dark nights (LD; 14 h of 150 lux:10 h of 0 lux) or light days and low level light at night (LAN; 14 h of 150 lux:10 h of 5 lux). Mice exposed to LAN on three consecutive nights increased depressive-like responses compared to mice housed in dark nights. In addition, female mice exposed to LAN increased central tendency in the open field. LAN was associated with reduced hippocampal vascular endothelial growth factor-A (VEGF-A) in both male and female mice, as well as increased VEGFR1 and interleukin-1beta mRNA expression in females, and reduced brain derived neurotrophic factor mRNA in males. Further, LAN significantly altered circadian rhythms (activity and temperature) and circadian gene expression in female and male mice, respectively. Altogether, this study demonstrates that acute exposure to LAN alters brain physiology and can be detrimental to well-being in otherwise healthy individuals.
