The thermal emission spectra of ultra-hot Jupiters typically have muted spectral features and thus closely resemble blackbodies in existing narrowband measurements2,3. The interpretation of these spectra has been controversial, with some studies claiming that the data are indicative of high metallicities ...
Through calculation and analysis of different types of test functions, it can show the performance of the algorithm more effectively and comprehensively. Table 3 Benchmark test functions. Full size table To verify the performance of the IGWOA algorithm proposed in this paper, several classical and ...
1b). This was similar to the particle number and size distributions in measurements of jet engine exhaust conducted in a jet engine test facility (see Additional file 1: Figure S1 B). In the size-resolved mass distributions for PL, PA, and FT, there was a mode around 150–200 nm ...

Furthermore, flux chambers provide a snap-shot measurement in time over a few measurement locations under good weather conditions, where results are not representative of spatial and temporal variability. Recently, regulatory guidance for the quantification of area fugitive emissions at oil sands mines ...
suggesting that the jet engine combustion particles are below 10 nm in aerodynamic diameter (Fig.1b). This was similar to the particle number and size distributions in measurements of jet engine exhaust conducted in a jet engine test facility (see Additional file1: Figure S1 B). In the si...
This suggests that there was no ongoing myocyte necrosis at the time of imaging and that troponin is a poor screening test for ongoing inflammation. However, we did identify elevations in systemic inflammatory biomarkers in participants with focal FDG uptake. This supports the biological plausibility ...

3, seeks to maximize the log-likelihood function and assigns the scattered emission photons of the ghost images to the original spatial locations. During the iterative process we defined two constraints; first total number of photons of the MMM images is constant before and after the processing, ...
In practice, using amyloid PET imaging one can rigorously and directly test pre-specified hypotheses on both the quantitative and spatial associations of various indirect markers of CAA-related brain injury with vascular Aβ burden. However, only limited studies have been reported to date, typically...
