Non-invasive anemia detection from conjunctiva and sclera images using vision transformer with attention map explainability [PDF]

open access: yesScientific Reports
Iron-deficiency anemia, a prevalent global health issue, traditionally requires invasive procedures for accurate diagnosis, such as a blood sample for measuring hemoglobin (Hgb) concentration.

Addressing pathological deficiencies in the simulation of complex charged fluids using neural network force fields [PDF]

open access: yesScientific Reports
In this work, we evaluate the capability of Neural Network-based force fields, particularly NeuralIL (J Chem. Inf. Model. 62, 88-101, 2021), to simulate complex charged fluids.

Multi-beam vortex generation induced by the non-linear optical anisotropy of graphene [PDF]

open access: yesEPJ Web of Conferences, 2022
We analyse the high harmonic emission from single-layer graphene driven by infrared vector beams. We demonstrate that graphene’s anisotropy offers a privileged scenario to explore non-trivial light spin-orbit couplings, which substantially extends the ...

Fourier-limited attosecond pulse generation with magnetically pumped high-order harmonic generation [PDF]

open access: yesEPJ Web of Conferences, 2022
After more than two decades of attosecond physics, the generation and control of the shortest laser pulses available remains as a complex task. One of the main limitations of reducing the temporal duration of attosecond pulses emitted from high-order ...

Ultra-high phase-locked harmonic generation from magnetic transversal confinement of electrons [PDF]

open access: yesEPJ Web of Conferences, 2023
The technological refinements on high-power laser systems of Petawatt class unveil scenarios for light-matter interaction beyond the laser-plasma perspective.

Ultraestable spatiotemporal characterization of optical vortices in the visible and near infrared [PDF]

open access: yesEPJ Web of Conferences, 2022
We show the versatility of the bulk lateral shearing interferometer characterizing complex spatiotemporal structures in different spectral ranges. Specifically, we have characterized constant and timevarying optical vortices in the visible and near ...

Machine-learning applied to the simulation of high harmonic generation driven by structured laser beams [PDF]

open access: yesEPJ Web of Conferences, 2023
High harmonic generation (HHG) is one of the richest processes in strong-field physics. It allows to up-convert laser light from the infrared domain into the extreme-ultraviolet or even soft x-rays, that can be synthesized into laser pulses as short as ...

Pulse self-compression down to the sub-cycle regime in hollow capillary fibers with decreasing pressure gradients [PDF]

open access: yesEPJ Web of Conferences, 2022
We theoretically demonstrate an enhancement in the generation of clean, near-infrared sub-cycle laser pulses by soliton self-compression in gas-filled hollow capillary fibers using decreasing pressure gradients. Furthermore, we identify the optimal input

Fuente alterna de energía renovable: Celdas solares orgánicas

open access: yesEntreciencias: Diálogos en la Sociedad del Conocimiento, 2013
Las celdas solares como fuente de energía renovable basadas en materiales inorgánicos han mostrado un gran desarrollo en las últimas décadas, sin embargo el alto costo de su producción ha imposibilitado su amplio uso.
