Application of 3D scanning technology in Royal Malaysian Air Force Industrial Revolution 4.0‐based aircraft maintenance

IET Networks, EarlyView., 2022
Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Preliminary observations from the China Fengyun-4A Lightning Mapping Imager

, 2023
The Fengyun-4A (FY-4A) Lightning Mapping Imager (LMI) is the first satellite-borne lightning imager developed in China, which can detect lightning over China and its neighboring regions. In this study, the LMI-observed temporal and spatial variations of lightning activity were compared with Lightning Imaging Sensor (LIS) and World Wide Lightning ...

Single-Molecule Imaging and Spectroscopy Enables Quantification of Location-Dependent Light-Matter Interactions on Nanoantennas. [PDF]

Small Sci
The fluorescence intensity as well as the spectral shape of the emission of single dye molecules strongly depend on the molecules’ exact position relative to plasmonic nanoparticles in hybrid systems. By point‐spread function modification analysis, the vertical binding location of single fluorophores on gold nanocones is obtained and correlated to both

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.
