The Complete Life Cycle of Dark Spot NDS‐2018 on Neptune
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Hubble Space Telescope collected imaging data spanning the full lifetime of Neptune's dark spot NDS‐2018, which is the sixth large, persistent dark spot seen in the planet's atmosphere. Neptune's dark spots are thought to be anticyclonic vortices, although internal flows have never been directly measured to confirm their rotation. Previous

Visual Behavior in Inline Speed Skating: An Eye‐Tracking Evaluation for Performance Analysis
European Journal of Sport ScienceThis study analyzed oculomotor behavior (fixations and saccades) in 19 competitive inline speed skaters (5 males, 14 females; aged 10–26 years) from the Aragonese Skating Federation (Spain), comparing high‐performance (N1) and intermediate (N2) groups ...

Journal of the European Optical Society-Rapid PublicationsThe electromagnetic behavior of light at the interface between isotropic materials is governed by the Fresnel formulas. These formulas primarily describe the electric field and are straightforward to interpret when dealing with transparent materials and ...

Journal of the European Optical Society-Rapid PublicationsIn the present work, the viability of a novel recording geometry to produce reflection holographic couplers is analyzed. Recalling the idea of previous works, photopolymers are used as the recording material because they have been proven to be well ...

Analysis of the recording of Fibonacci lenses on photopolymers with 3-D diffusion model
Journal of the European Optical Society-Rapid PublicationsIn this work a three-dimensional diffusion model is used to model photopolymers as a recording media. This model allows us to predict the properties of the Diffractive Optical Elements (DOEs) once we recorded into the photopolymer.
