Preventive Effect of Upland Pigmented Potatoes Against LPS‐Induced Inflammation in THP‐1 Macrophages

open access: yesMolecular Nutrition &Food Research, EarlyView.
The anti‐inflammatory activity of extracts from three commercial potato varieties cultivated upland was investigated on THP‐1 macrophages insulted with LPS. While the chlorogenic acid (CGA)‐rich extract from Kennebec reduced inflammation only at supraphysiological doses, carotenoid‐rich Desirèe and anthocyanin (ACN)‐rich Bleuet decreased TNF‐α, IL‐1β ...

Free‐Space Diffraction and Interference in a Transformed Frame

open access: yesNatural Sciences, EarlyView.
In free propagation from a focus the Hermite–Gauss mode functions of optics, or the equivalent Harmonic Oscillator eigenfunctions of quantum mechanics spread in space. It is shown that a transformation to a frame travelling with the normals to the wave fronts gives the Gouy phase as proper position or time variable.

Multi‐Slit Diffraction in Scaled Space‐Time

open access: yesNatural Sciences, EarlyView.
A space‐time scaling is used to transform quantum wave packets describing free particle motion to packets moving in an effective harmonic oscillator potential that confines and directs the wave fronts along the classical phase space of the oscillator. The transformation is applied to multi‐slit diffraction and shown to characterize diffraction features

Low‐energy electron microscopy intensity–voltage data – Factorization, sparse sampling and classification

open access: yesJournal of Microscopy, Volume 289, Issue 2, Page 91-106, February 2023., 2023
Abstract Low‐energy electron microscopy (LEEM) taken as intensity–voltage (I–V) curves provides hyperspectral images of surfaces, which can be used to identify the surface type, but are difficult to analyse. Here, we demonstrate the use of an algorithm for factorizing the data into spectra and concentrations of characteristic components (FSC3) for ...
