Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

The Laspeyres bias in the Spanish consumer price index [PDF]

open access: yes, 2000
The CPI compares the cost of acquiring a reference quantity vector at current and base prices. Such reference vector is the vector of mean quantities actually bought by a reference population, whose consumption patterns are investigated during a period t

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

open access: yesSmart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

Is the temporomandibular joint affected by rheumatoid arthritis? A comparative investigation with knee arthritis in an experimental rat model

open access: yesJournal of Anatomy, Volume 249, Issue 1, Page 114-126, July 2026.
Animals were sensitized with mBSA emulsified in CFA/IFA and subsequently received three intra‐articular injections of mBSA into either the TMJ or the knee (once per week). Mechanical hyperalgesia was assessed using electronic von Frey testing after arthritis establishment at 24 h or 7 days following the third intra‐articular injection.
