Hybrid Deep Reconstruction for Vignetting-Free Upconversion Imaging through Scattering in ENZ Materials
Optical imaging through turbid or heterogeneous environments (collectively referred to as complex media) is fundamentally challenged by scattering, which scrambles structured spatial and phase information. To address this, we propose a hybrid-supervised deep learning framework to reconstruct high-fidelity images from nonlinear scattering measurements acquired with a time-gated epsilon-near-zero (ENZ) imaging system. The system leverages four-wave mixing (FWM) in subwavelength indium tin oxide (…

While Venezuela is not a democratic example like Ukraine, the echoes of Russia's invasion of Ukraine as Trump moves US military assets toward the Venezuelan coast are certainly there.
"Maduro spoke to the Venezuelan people on Monday, asking them to prepare for an invasion.
"In the face of this maximum military pressure, we have declared maximum preparedness for the defence of Venezuela," Maduro said of the deployment, which he characterized as "an extravagant, unjustifiable, immoral and absolutely criminal and bloody threat."
He deployed troops along the coast and at the border with Colombia. He also urged Venezuelans to enlist in a civilian militia.”

Ionic glass formers show an inverted relation between fragility and relaxation broadness
Supercooled liquids undergo a rapid change in dynamics as they are cooled to their glass transition temperature and turn from a flowing liquid into an amorphous solid. Depending on how steeply the viscosity changes with temperature around the glass transition, glass formers are classified as strong or fragile. An empirical relation exists between the fragility of the liquid and the broadness of its relaxation spectrum. However, the microscopic origins of this correlation remain unclear and its …
