This study aims at exploiting and processing multi-temporal satellite images of the Google Earth Engine platform (GEE), combined with topographic data since 1965 to monitor changes in estuary and shoreline of the coastal area of Cua Dai, Tra Khuc river, Quang Nam province during a period of 1965–2021. The analysis results show shoreline changes and hot spots of erosion and landslides along the coast, on both sides of Cua Dai river.

The paper "Applying machine learning algorithms to classify forest cover type from sentinel 2 MSI data" presents the results of forest cover classification in Dak Lak province from Sentinel 2 optical satellite image data using machine learning techniques. Sentinel 2 MSI images taken in November 2015 and December 2020 are used to classify forest cover objects and then evaluate forest cover changes in the period 2015-2020.

The study "Mangrove degradation assessment using WorldView-2 imagery for Mekong delta, Vietnam" reported research findings on mangrove degradation assessment using WorldView2-based NDVI and NDVI differencing techniques. NDVI was estimated through analysis of satellite images band ratio to give an indication of greenness and healthy forests. The findings contribute to identifying areas with high levels of degradation that need to prioritize restoration and conservation solutions.

This paper relies on remote sensing images, collected from Sentinel-2 satellite, to preliminarily map the green space in Da Nang city. The remote sensing data was collected in November 2022. The normalized difference vegetation index (NDVI) is used to recognize the green space pixels. Based on this preliminary study, the area of green space in Da Nang city is approximately 140 km2 , which occupies roughly 56% of the total urban area.

Invasive species threaten the biodiversity and the function of ecosystems. Drone image, satellite images, and image analysis software were used to create the map of invasive distribution and the potential spreading of invasive plants. 13 most invasive plants were identified with 11 species listed as invasive species in Southeast Asia and 5 of them in the 100 world’s invasive species by IUCN.

Growing evidence has shown that unilateral nerve injury results in pain hypersensitivity in the ipsilateral and contralateral sides respective to the injury site. This phenomenon is known as mirror image pain (MIP). Glial cells have been indicated in the mechanism of MIP; however, it is not clear how glial cells are involved in MIP.
