1. How strong are the links between global warming and surface solar radiation changes? 

   Stamatis M.; Hatzianastassiou N.; Korras-Carraca M.B.; et al. (2024)

   Climatic Change

   The aim of this study is to investigate the possible relationship between the recent global warming and the interdecadal changes in incoming surface solar radiation (SSR), known as global dimming and brightening (GDB). The analysis is done on a monthly and annual basis on a global scale for the 35-year period 1984–2018 using surface temperature data from the European Centre for Medium-Range Weather Forecasts (ECMWF) v5 (ERA5) reanalysis ...

2. Non-holomorphic modular forms from zeta generators 

   Dorigoni D.; Doroudiani M.; Drewitt J.; et al. (2024)

   Journal of High Energy Physics

   We study non-holomorphic modular forms built from iterated integrals of holomorphic modular forms for SL(2, ℤ) known as equivariant iterated Eisenstein integrals. A special subclass of them furnishes an equivalent description of the modular graph forms appearing in the low-energy expansion of string amplitudes at genus one. Notably the Fourier expansion of modular graph forms contains single-valued multiple zeta values. We deduce the ...

3. Kalman filter-driven state observer for thermal error compensation in machine tool digital twins 

   Lang S.; Talleri S.; Mayr J.; et al. (2024)

   Manufacturing Letters

   Sustainable reduction of thermal errors during production is the key challenge in modern high-precision manufacturing. Numerical compensation models provide an energy-efficient solution, but in the case of data-driven models, high-quality experimental data must be time-consuming and expensive to produce, negatively impacting overall productivity. Furthermore, robustness concerns arise in the case of new operating conditions, which were ...

4. Effects of winter soil warming on crop biomass carbon loss from organic matter degradation 

   Ni H.; Hu H.; Zohner C.M.; et al. (2024)

   Nature Communications

   Global warming poses an unprecedented threat to agroecosystems. Although temperature increases are more pronounced during winter than in other seasons, the impact of winter warming on crop biomass carbon has not been elucidated. Here we integrate global observational data with a decade-long field experiment to uncover a significant negative correlation between winter soil temperature and crop biomass carbon. For every degree Celsius ...

5. Too hot to print, too slow to handle; finding optimal path characteristics for WAAM 

   Sideris I.; Petrik J.; Bambach M. (2024)

   Manufacturing Letters

   Wire + Arc Additive Manufacturing (WAAM) is recognized as a highly capable metal additive process. However, the quality of manufactured parts is often compromised by defects stemming from process-induced temperature fields and transient weld-bead shapes, largely due to suboptimal path planning. Recent efforts have predominantly focused on optimizing either the thermal aspects or the productivity of WAAM, but the interplay between these ...
