Advanced Photonics Research, Volume 7, Issue 7, July 2026.A hybrid‐structured pentagonal‐core photonic crystal fiber sensor operating in the terahertz regime is proposed for fuel adulteration detection. Numerical analysis using the finite element method in COMSOL shows optimal performance at 2 THz, achieving high relative sensitivity (up to 98.20%) with ultralow confinement loss (~10−¹³ dB/m). The design also

Journal 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.

Nanophotonics, Volume 15, Issue 12, 25 June 2026.A hybrid metasurface composed of Ge dielectric pillars and a VO₂ grating is proposed, which enables functional switching between symmetric and asymmetric polarization conversion in transmission. By continuously tuning the conductivity of VO2, the structure achieves multiple dynamic controls of asymmetric transmission, circular dichroism, and ...
