This study introduces a novel methodology for estimating and analysing coastal cliff degradation, using machine learning and remote sensing data. Degradation refers to both natural abrasive processes and damage to coastal reinforcement structures caused by natural events. We utilized orthophotos and LiDAR data in green and near-infrared wavelengths to identify zones impacted by storms and extreme weather events that initiated mass movement processes.

Article Synopsis
- Chemiluminescence (CL) is a chemical reaction that produces light without needing external energy sources, offering advantages in sensitivity and imaging.
- Researchers developed a series of unimolecular probes that emit light in the near-infrared (NIR-II) range for better imaging, specifically targeting wavelengths up to 1060 nm.
- The study successfully demonstrated these probes for real-time detection of superoxide anions in a mouse model of liver injury, highlighting their potential for advanced bioimaging and disease diagnosis.
Introduction: Cerebral oximetry measurement using near-infrared spectroscopy (NIRS) has been highlighted as a technology that can provide noninvasive information on regional cerebral oxygen saturation (rSO2) during CPR even though its effectiveness has not been fully confirmed. The research focuses on the use of NIRS to predict the return of spontaneous circulation (ROSC) and neurological outcomes.
Objectives: The purpose of the study is to evaluate the validity of using regional cerebral oxygen saturation (rSO2) measurement compared to ETCO2 during CPR to and its association with ROSC, as well as to evaluate the neuroprognostic value of NIRS.

The black soldier fly larvae (BSFL) are well known to utilise a wide variety of organic waste streams, delivering a product rich in protein (30-50%) and lipids (15-49%) and other micronutrients. The objective of this study was to evaluate the ability of NIR spectroscopy combined with chemometrics to predict the concentration of fatty acids in BSFL reared in different commercial waste streams. Intact BSFL samples were analysed using a bench top NIR instrument where calibration models for fatty acids were developed using partial least squares (PLS) regression.
