Three nontrivial solutions for Neumann problems resonant at any positive eigenvalue
Le Matematiche, 2010 We consider a semilinear Neumann problem with a parametric reaction which has a concave term and a perturbation which at ±∞ can be resonant with respect to any positive eigenvalue.

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Air–sea feedback in the northeastern tropical Atlantic in boreal summer at intraseasonal time‐scales
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates air–sea interactions in the northeastern tropical Atlantic at intraseasonal time‐scales, focusing on the feedback between sea‐surface temperature (SST) and surface winds. It finds that trade wind anomalies drive SST changes, creating a feedback loop that lasts 2–3 weeks.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We study the impact of observation‐error correlations in data assimilation using both a simple idealised system and a more realistic configuration. A spectral analysis of data assimilation in the idealised system allows us to gain insights on the effect of observation‐error correlations, which are then validated using the realistic configuration.

Statistical Complexity of Quantum Learning
Advanced Quantum Technologies, EarlyView.The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...
