New, Low-Cost, Hand-Held Multispectral Device for In-Field Fruit-Ripening Assessment

open access: yesAgriculture, 2022
The state of ripeness at harvest is a key piece of information for growers as it determines the market price of the yield. This has been traditionally assessed by destructive chemical methods, which lead to low-spatiotemporal resolution in the ...

Dark matter line searches with the Cherenkov Telescope Array [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from astrophysical or instrumental backgrounds. We provide an updated assessment

Flat clathrin lattices are dynamic actin-controlled hubs for clathrin-mediated endocytosis and signalling of specific receptors

open access: yesNature Communications, 2017
Clathrin lattices at the plasma membrane coat both invaginated and flat regions forming clathrin-coated pits and clathrin plaques, respectively. The function and regulation of clathrin-coated pits in endocytosis are well understood but clathrin plaques ...

Accelerometry-Based Distance Estimation for Ambulatory Human Motion Analysis

open access: yesSensors, 2018
In human motion science, accelerometers are used as linear distance sensors by attaching them to moving body parts, with their measurement axes its measurement axis aligned in the direction of motion. When double integrating the raw sensor data, multiple
