Article Abstract
An optical frequency transfer system was designed aiming at silicon photonics integration. To evaluate the expected performance before fabricating the photonic integrated circuits, an experimental simulator was developed by employing alternative optics that were replaceable with the corresponding photonic functions. In particular, a carrier-suppressed single-sideband Mach-Zehnder modulator was first exploited as a double-pass phase-compensation actuator in fiber-induced noise cancellation. Experimental simulation in a 90 km length fiber network demonstrated an instability of 2 × 10-18 for the transmitted optical frequency and uninterrupted operations over 24 h. By adopting the design established here, a chip-scale and highly accurate optical frequency transfer system is feasible for numerous applications.

Photonic Reservoir Computing (RC) systems leverage the complex propagation and nonlinear interaction of optical waves to perform information processing tasks. These systems employ a combination of optical data encoding (in the field amplitude and/or phase), random scattering, and nonlinear detection to generate nonlinear features that can be processed via a linear readout layer. In this work, we propose a novel scattering-assisted photonic reservoir encoding scheme where the input phase is deliberately wrapped multiple times beyond the natural period of the optical waves [0,2π).

Purpose: To explore the causal links between antihypertension drugs usage and age-related macular degeneration (AMD).
Methods: Multiple genetic analyses, including summary data-based Mendelian randomization (SMR), traditional MR, and colocalization analysis, were used to explore the causal associations between antihypertension drugs and AMD. Clinical data from the UK Biobank and the National Health and Nutrition Examination Survey (NHANES) was applied to refined risk assessment of specific antihypertensive medications in the context of AMD development.

Purpose: To assess macular choriocapillaris (CC) metrics in healthy volunteers (HVs) without ocular disease and demonstrate CC variations in patients with inherited retinal dystrophies (IRDs) using adaptive optics optical coherence tomography angiography (AO-OCTA).
Methods: Twenty-one HVs and three IRD patients were imaged. Macular variation in 20 HVs in CC metrics (CC density, CC diameter, CC tortuosity, void diameter, void area, lobule count, lobule area, and RPE-CC distance) were assessed by imaging a 28° strip of overlapping AO-OCTA volumes (3° × 3°) from the optic nerve head to the temporal macula.

Antimony selenide (SbSe), a narrow-bandgap semiconductor with strong light absorption, exhibits photoresponse up to ≈1050 nm due to its intrinsic 1.15 eV bandgap. To extend detection into the near-infrared (NIR, 700-1350 nm), Bi-alloyed (BiSb)Se is developed via vacuum sputtering and postselenization.

Oropouche virus (OROV) is emerging as a growing public health concern, with increasing numbers of case, an expanding global spread and the potential for severe clinical outcomes. However, despite the increasing incidence, the clinical features of OROV infections have not yet been thoroughly examined. The present systematic review and meta-analysis aimed to investigate the prevalence of clinical manifestations in OROV infections.
