physica status solidi (RRL) – Rapid Research Letters, EarlyView.Energetic particles make space a harsh environment that solar cells must endure. This study demonstrates that proton flux critically affects radiation damage in Cu(In,Ga)Se2 solar cells. By irradiating identical cells at different fluxes, a flux‐dependent balance between defect generation and dynamic annealing was revealed.

A Method to Improve the Analysis of Cluster Ensembles [PDF]
, 2014 Clustering is fundamental to understand the structure of data. In the past decade the cluster ensembleproblem has been introduced, which combines a set of partitions (an ensemble) of the data to obtain a singleconsensus solution that outperforms all the ...

Assessing wildfire dynamics during a megafire in Portugal using the MesoNH/ForeFire coupled model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Weather conditions affect megafires by inducing different fire behaviors over several days or weeks. The coupled MesoNH/ForeFire code was used to represent the dynamics of fire generating pyro‐convective clouds. To advance the understanding of wildfire dynamics, high‐resolution coupled fire–atmosphere modeling was employed.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis
Advanced Quantum Technologies, EarlyView.By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Journal of Field Robotics, EarlyView.ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...
