Day-night genes and their associated binomial P value.

open access: yes, 2023
For each gene, the number of tissues for which the gene is day or night, for (i) all tissues, (ii) non-brain tissues, and (iii) brain tissues. For each of the previous tissue classification, a binomial P value is associated to test if the gene has a ...

Improved NOAA-20 Visible Infrared Imaging Radiometer Suite Day/Night Band Image Quality by Upgraded Gain Calibration

open access: yesRemote Sensing, 2021
Due to complex radiometric calibration, the imagery collected by the Day/Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar Partnership (Suomi-NPP) and the NOAA-20 follow-on satellite is subject to ...

Automatic Boat Identification System for VIIRS Low Light Imaging Data

open access: yesRemote Sensing, 2015
The ability for satellite sensors to detect lit fishing boats has been known since the 1970s. However, the use of the observations has been limited by the lack of an automatic algorithm for reporting the location and brightness of offshore lighting ...

A visible-infrared double band photodetector absorber

open access: yesResults in Physics, 2020
In this paper, a double-band visible-infrared photodetector absorber is proposed, which consists of a modified microbolometer and a metallic reflective layer which has a deep well. The simulated results show that the absorber proposed has high absorption

Statistical analysis of night radiance RH using VIIRS day/night band satellite time series data [PDF]

open access: yes, 2019
Amount of night lights in an area is a proxy indicator of electricity consumption. This is interlinked to indicators of economic growth such as socio-economic activities, urban population size, physical capital, incidence of poverty.

The effects of day and night temperature on Chrysanthemum morifolium: investigating the safe limits for temperature integration [PDF]

open access: yes, 2009
The impact of day and night temperatures on pot chrysanthemum (cultivars ‘Covington’ and ‘Irvine’) was assessed by exposing cuttings, stuck in weeks 39, 44, and 49, to different temperature regimes in short-days. Glasshouse heating setpoints of 12°, 15°,
