Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

PARCE: Accurate Inference of Crystal Structure Information From Phonon Vibrational Modes

Materials Genome Engineering Advances, EarlyView.
In this work, we introduce a multidescriptor framework and accuracy‐adaptive ensemble network to classify over 30,000 crystals from phonon and Raman data, achieving > 60% accuracy across diverse structures. Our work reduces reliance on ideal XRD data, enabling automated and large‐scale material structure analysis.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Electrostatic Control of Terahertz High‐Harmonic Generation in Turbostratically Stacked Graphene

Small Methods, EarlyView.
This study investigates electrostatic control of terahertz high‐harmonic generation in top‐gated turbostratic multilayer graphene. A quantitative model combining graphene's thermodynamic nonlinear terahertz response with multilayer bias screening reproduces the experimental yields.

Current Advances of Treatments, Therapeutic Targets, Biomarkers, Novel Drugs, and Machine Learning for Hypopharyngeal Squamous Cell Carcinoma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive subtype of head and neck squamous cell carcinoma with insidious onset, early metastasis, and dismal prognosis. Conventional multimodal therapy achieves limited survival benefit, highlighting an urgent need for refined precision strategies.
