Assessing vegetation response to drought in the northern Great Plains using vegetation and drought indices
Lei Ji,Albert J. Peters +1 more
TL;DR: The relationship between vegetation vigor and moisture availability, however, is complex and has not been adequately studied with satellite sensor data as mentioned in this paper, however, an analysis was conducted on time series of monthly NDVI (1989-2000) during the growing season in the north and central U.S. Great Plains.
Journal ArticleDOI
Analysis of Dynamic Thresholds for the Normalized Difference Water Index
Lei Ji,Li Zhang,Bruce K. Wylie +2 more
TL;DR: In this article, the normalized difference water index (NDWI) has been successfully used to delineate surface water features, but two major problems have often encountered: (a) NDWIs calculated from different band combinations [visible, nearinfrared, or shortwave-infrared (SWIR)] can generate different results, and (b) NDWI thresholds vary depending on the proportions of subpixel water/non-water components.
Journal ArticleDOI
Recent developments in and perspectives on three-coordinate boron materials: a bright future.
TL;DR: This work highlights recent developments in the synthesis, optical and electronic properties of 3-coordinate boron compounds and their applications in materials.
Journal Article
Drought Monitoring with NDVI-Based Standardized Vegetation Index
TL;DR: In this article, the authors used the Normalized Difference Vegetation Index (NDVT) to estimate the probability of occurrence of the present vegetation condition at a given location relative to the possible range of vegetative vigor, historically.
Journal ArticleDOI
Bioapplications of small molecule Aza-BODIPY: from rational structural design to in vivo investigations.
Zhenxiong Shi,Xu Han,Wenbo Hu,Hua Bai,Bo Peng,Lei Ji,Quli Fan,Lin Li,Wei Huang,Wei Huang,Wei Huang +10 more
TL;DR: This review is aimed at providing an insightful design guideline and a clear overview of Aza-BODIPY dyes, which might entice new ideas and directions in this field.
