Performance of intrinsic and soil line-based vegetation indices to mangrove mapping in Malaysia. [PDF]

, 2011
The use of vegetation indices of remote sensing data in vegetation mapping has been long recognised. However, the accuracy of mapping through the use of vegetation indices model has limitations, and has so far not been investigated.

ANALYSIS OF BURNED VEGETATION RECOVERY BY MEANS OF VEGETATION INDICES

SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2019
One of the largest fires in the Croatian history, so called ‘mother of all fires’, broke out on Monday, 17. July 2017 in the area between Split and Omis (Croatia). The fighting with the firestorm lasted until 18. July when the situation was put under control, and on 19. July, the recovery of the affected area started. The classification showed that the

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

Comparison of Pre‐ and Postoperative Gut Microbiota Diversity in Patients With Rectal Cancer Undergoing Stoma Creation and Closure

Annals of Gastroenterological Surgery, EarlyView.
We investigated the impact of temporary stoma creation and closure on gut microbiota diversity in rectal cancer patients. 16S rRNA sequencing revealed that microbial diversity significantly decreased postoperatively in the stoma group but remained stable in non‐stoma patients.

Characterization of the climate-vegetation-soil complexity using vegetation indices

, 2023
Multiple studies describe vegetation as a spatial-time-varying complex ecological system, varying in time and space, with non-linear relationships between the different variables. Therefore, developing and implementing methodologies that allow us to broaden our knowledge of the system is essential.

Significance of Self‐Expandable Metallic Stent for Postoperative Intra‐Abdominal Infection After Pancreatoduodenectomy in Patients With a Hard Pancreas

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Self‐expandable metal stents (SEMS) are often used for preoperative biliary drainage in pancreatoduodenectomy (PD); however, their impact on postoperative intra‐abdominal infection (POAI) remains unclear. This study aimed to evaluate the clinical significance of SEMS in relation to POAI.

Impact of Biomimetic Pinna Shape Variation on Clutter Echoes: A Machine Learning Approach

Advanced Intelligent Systems, EarlyView.
Bats with dynamic ear structures navigate dense, echo‐rich environments, yet the echoes they receive are highly random. This study shows that machine learning can reliably detect structural signatures in these seemingly chaotic biosonar signals. The results open new directions for biologically inspired sensing, where time‐varying receiver shapes ...

Machine Learning Vegetation Filtering of Coastal Cliff and Bluff Point Clouds

Remote Sensing
Coastal cliffs erode in response to short- and long-term environmental changes, but predicting these changes continues to be a challenge. In addition to a chronic lack of data on the cliff face, vegetation presence and growth can bias our erosion ...
