Temperature characteristics of Pockels electro-optic voltage sensor with double crystal compensation

AIP Advances, 2016
Voltage sensors based on the Pockels electro-optic effect in LiNbO3 crystals have been applied to practical engineering measurements because of their passive nature, wide operating bands, and low transmission loss.

Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

Ibrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

Estradiol replacement attenuates alendronate‐associated adverse effects on alveolar bone repair in ovariectomized rats

Journal of Periodontology, EarlyView.
Abstract Background Sodium alendronate (ALN) is widely used to treat postmenopausal osteoporosis, but both estrogen deficiency and antiresorptive therapy may impair alveolar bone repair after tooth extraction. A clinically relevant but insufficiently explored scenario involves estrogen‐deficient individuals receiving hormone replacement therapy (HRT ...

Age‐related local versus systemic early phase wound healing dynamics following free gingival graft harvest

Journal of Periodontology, EarlyView.
Abstract Background Free palatal gingival grafts (FGG) are commonly harvested during mucogingival procedures. The present study investigates age‐related local and systemic early secondary wound healing outcomes, following FGG harvest in a rat model. Methods A 4.2 mm diameter defect was created in the palate of 24 younger (2 m) and 24 older (6 m) Wistar

Minimization of Temperature Effects of High-Birefringent Elliptical Fibers for Polarmetric Optical-Fiber Sensors [PDF]

, 1994
The temperature dependence of polarization-maintaining fibers is a problem in polarimetric optical-fiber sensors. We report a novel method for making a temperature-insensitive, polarization-maintaining fiber, which may be used for the sensing part in a ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

Limnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Coccolithophore particulate inorganic and organic carbon ratios: An evaluation of acid decalcification methods

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Bridging Classical and Quantum Approaches for Quantitative Sensing of Turbid Media with Polarization‐Entangled Photons

Laser &Photonics Reviews, EarlyView.
This work bridges classical and quantum polarimetry toward quantitative quantum photonic sensing of turbid environments. Theoretical and experimental investigations reveal how polarization‐entangled photonic states evolve in turbid media, uncovering robust trends in entanglement evolution and paving the way for advanced quantum sensing in biomedical ...
