Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

The Application of Telemedicine in Surgery

open access: yesMed Research, EarlyView.
This figure provides an overview of the content presented in this article. Telemedicine is integrated throughout the entire surgical workflow, with distinct applications across the preoperative, intraoperative, and postoperative phases. These applications are enabled by a suite of supporting technologies, while the associated implementation challenges ...

Interdiction Models and Heuristics for Graph Propagation

open access: yesNetworks, EarlyView.
ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Impact of Weak‐Constraint Four‐Dimensional Variational data assimilation on the prediction of a sudden stratospheric warming event in 2024

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The Weak‐Constraint Four‐Dimensional Variational (WC‐4DVAR) system markedly improved the analysis and forecasting of the 2024 sudden stratospheric warming (SSW) event. It reduced biases and enhanced 7–9 day predictions of temperature across the SSW life cycle, with the most pronounced gains for winds also during the critical onset period.
