Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Impact of tear morphology and meniscal laterality on repair failure in stable knees: Medial repairs show over twofold risk

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the failure rates of all‐inside meniscal repair based on tear morphology in stable knees (i.e., without concomitant anterior cruciate ligament reconstruction [ACLR]) and to assess the influence of failure. Methods This retrospective cohort study included 1008 patients who underwent arthroscopic all‐inside meniscal repair ...

High failure rate after all‐inside revision meniscal repair: Female sex and absence of ACL reconstruction increase risk

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine the failure rate and identify factors associated with failure following all‐inside revision meniscal repair in patients with persistent or recurrent symptoms after primary meniscal repair. Methods This was a retrospective cohort study including 108 consecutive patients who underwent arthroscopic all‑inside revision ...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, EarlyView.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

Laser &Photonics Reviews, EarlyView.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures

Laser &Photonics Reviews, EarlyView.
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

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

Laser &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.

Parallel Multi‐Target Detection for Quantum LiDAR

Laser &Photonics Reviews, EarlyView.
Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

High‐Speed Integrated Graphene‐Silicon Slot‐Waveguide Electro‐Absorption Modulator at 2 and 1.5 µm Wavebands

Laser &Photonics Reviews, EarlyView.
A high‐speed, efficient, robust, and compact 2‐μm$\mathrm{\mu}\mathrm{m}$ waveband E/O absorption modulator based on a graphene‐silicon slot waveguide is demonstrated. This work represents a significant advancement towards the realization of high‐speed integrated E/O modulators for optical communication systems operating at the 2‐μm$\mathrm{\mu}\mathrm{
