Computing modular coincidences can show whether a given substitution system, which is supported on a point lattice in R, consists of model sets or not. We prove the computatibility of this problem and determine an upper bound for the number of iterations needed. The main tool is a simple algorithm for computing modular coincidences, which is essentially a generalization of Dekking coincidence t...
The ionization dynamics of pure He nanodroplets irradiated by Extreme ultraviolet radiation is studied using Velocity-Map Imaging PhotoElectron-PhotoIon COincidence spectroscopy. We present photoelectron energy spectra and angular distributions measured in coincidence with the most abundant ions He(+), He2(+), and He3(+). Surprisingly, below the autoionization threshold of He droplets, we find ...
There is a consensus that turbulence-free images cannot be obtained by conventional computational ghost imaging (CGI) because the CGI only classic simulation, which does not satisfy conditions of imaging. In this article, we first report turbulence-immune method based on multi-scale generative adversarial network (MsGAN). Here, framework changed, but coincidence measurement algorithm optimized ...
* Correspondence: hassen. [email protected] Institut Supérieur d’Informatique et des Technologies de Communication de Hammam Sousse, Université de Sousse, Route GP1-4011, Hammam Sousse, Tunisie Full list of author information is available at the end of the article Abstract In this article, we present tripled coincidence point theorems for F: X ® X and g: X ® X satisfying weak -contractions in p...
The choice of injected dose of 18 F -FDG and acquisition time is important in obtaining consistently high-quality PET images. The aim of this study was to determine the optimal acquisition protocols based on patient weight for 3-dimensional lutetium oxyorthosilicate PET/CT. Methods: This study was a retrospective analysis of 76 patients ranging from 29 to101 kg who were injected with 228–395.2 ...
UNLABELLED The choice of injected dose of (18)F-FDG and acquisition time is important in obtaining consistently high-quality PET images. The aim of this study was to determine the optimal acquisition protocols based on patient weight for 3-dimensional lutetium oxyorthosilicate PET/CT. METHODS This study was a retrospective analysis of 76 patients ranging from 29 to 101 kg who were injected wi...
Weyl’s antiquated idea of scale invariance was resurrected by Cheng in 1988, almost 60 years later. The requirement of local scale invariance leads to the existence of a completely new vector field, which we call as “Cheng-Weyl vector field”. The Cheng-Weyl vector field only couples to the scalar field and the gravitational field naturally. It does not interact with other known matters in the p...
We present the first results using a new technique that combines femtosecond pump–probe methods with energyand angle-resolved photoelectron–photoion coincidence imaging. The dominant dissociative multiphoton ionization ~DMI! pathway for NO2 at 375.3 nm is identified as three-photon excitation to a repulsive potential surface correlating to NO(C P)1O(P) followed by one-photon ionization to NO(X ...
