In-flight calibration confirms LEIA performs as designed
—
in AstronomyWhat the study found The Lobster Eye Imager for Astronomy (LEIA) showed in-orbit performance that generally matched its design and ground expectations. The study reports that its spatial resolution, source positioning, effective area, energy response, and background behavior were all characterized and were largely consistent with prior values or models. Why the authors say this…
Post-processing improved wind-speed ensemble forecasts
—
in MeteorologyWhat the study found Post-processing generally improved both probabilistic calibration and point forecast accuracy for wind-speed ensemble forecasts. The study also found that spatial resolution was more important than ensemble size in these forecasts. Why the authors say this matters The authors conclude that forecast skill can be changed substantially by statistical calibration, which reduces…
Unweighted HJM setting supports yield-curve modeling with negative yields
New approach to Heath–Jarrow–Morton framework using unweighted function spaces and functional PCA, enabling better yield curve modeling with support for negative interest rates.
Integrated calibration improved Nile River model performance
Integrated sensitivity-optimisation framework for calibrating hydrodynamic and water-quality models applied to the Nile River using Brute-Force analysis and Dual-Annealing optimisation.
Dataset covers sewer flow, pollution, and rain observations from 2008 to 2011
Four years of continuous sewer hydraulic and water quality data from Austria with precipitation records and hydrodynamic model for combined sewer system analysis and pollutant transport research
