An EARLINET early warning system for atmospheric aerosol aviation hazards
(European Geosciences Union (EGU), 2020-09-15)
Article.
Accés obert

Deep learning (DL) models have provided the state-of-the-art performance in a wide variety of medical imaging benchmarking challenges, including the Brain Tumor Segmentation (BraTS) challenges. However, the task of focal ...
Spiraling vortices in exciton-polariton condensates
(American Physical Society (APS), 2020-07-23)
Article.
Accés obert
Article.
Accés obert
We introduce the phenomenon of spiraling vortices in driven-dissipative (nonequilibrium) exciton-polariton condensates excited by a nonresonant pump beam. At suitable low pump intensities, these vortices are shown to spiral ...
Combining Swarm Langmuir probe observations, LEO-POD-based and ground-based GNSS receivers and ionosondes for prompt detection of ionospheric earthquake and tsunami signatures: Case study of 2015 Chile-Illapel event

Article.
Accés obert
Article.
Accés obert
The study investigates ionospheric electric field responses to the earthquake (EQ) of magnitude 8.3, and the related seismic activity and tsunami triggered by the mainshock in Chile-Illapel region, at 22:54 UTC, in the ...
A comparative analysis of aerosol optical coefficients and their associated errors retrieved from pure-rotational and vibro-rotational raman lidar signals
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-11)
Article.
Accés obert
Article.
Accés obert
This paper aims to quantify the improvement obtained with a purely rotational Raman (PRR) channel over a vibro-rotational Raman (VRR) channel, used in an aerosol lidar with elastic and Raman channels, in terms of signal-to-noise ...
Context-unsupervised adversarial network for video sensors
