Prognostic Value of Cranial Nerve Invasion in T4‐Stage Nasopharyngeal Carcinoma: A Retrospective Cohort Study With a Median Follow‐Up of 136 Months

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background The objective of this study was to evaluate the prognostic value of cranial nerve invasion (CNI) in T4‐stage nasopharyngeal carcinoma (NPC) patients with nonmetastatic. Methods We retrospectively analyzed 299 T4‐stage NPC patients with nonmetastatic disease in the Cancer Hospital of Shantou University Medical College.

Octave‐Spanning, Deterministic Single Soliton Generation in 4H‐Silicon Carbide‐On‐Insulator Microring Resonators

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...
