Quantitative evaluation of methods to analyze motion changes in single-particle experiments
Datasets and ground truth
In order to benchmark the different methods on data with a known ground truth, we relied on numerical simulations. We developed the andi-datasets Python package71 to generate the required datasets to train and evaluate…

The first observations of auroras with dynamic vision sensors
DVS noise filtering
Two types of noise are apparent: hot pixels and front-end noise. Hot pixels generate excessive amounts of the same polarised events, several magnitudes higher than the regular scene event rate. The front-end noise has several…

Reconfigurable binary and ternary logic devices enabling logic state modulation
Figure 1a presents a schematic illustration of the structure of the reconfigurable binary–ternary transistor developed in this study. The device comprises two bottom-gate bottom-contact n-type semiconductor channels connected in series. An…

Ultrafast core-to-core luminescence in BaF2 – LaF3 single crystals
Characterizations of the crystals
The unit cell parameters of the BaF2-LaF3 crystals were examined by XRD (Fig. 2). With increasing the LaF3 concentration, the unit cell parameter a decreased slightly without changes in the Fm-3m space group…

Temperature-tunability of perovskite quasi-bound states in the continuum-metastructure for enhanced terahertz performance and CO2 sensing
MAPbI3 characteristics
The complex refractive index of MAPbI3 is calculated using Eqs. (1–5) in the supplementary information and is depicted in Fig. 3. Since we use x- and y-polarized light to investigate the optical response of the…

Parameterized quantum circuits as universal generative models for continuous multivariate distributions
In this section, we introduce expectation value sampling models and define precisely the universality property for generative models. We state formally our first main result, namely the existence of two universal families of expectation value…

Study of trijet production in proton-proton collisions at different energies
Using Monte Carlo (MC) event generator is a method to simulate the kinds of events that should be produced at the LHC in proton-proton collisions. They also provide helpful guidance for selecting or developing existing experiments as well as…
