A Knowledge‐Augmented Wearable System for Interpretable Plant Health Monitoring
FlexTech, EarlyView.We present K‐Wear, a knowledge‐augmented wearable system for interpretable plant health monitoring. A soft multimodal sensing platform continuously captures spectral, humidity, and temperature signals from plant leaves, which are processed through a knowledge‐guided large language model reasoning framework to generate mechanistic diagnoses and ...

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers
Laser &Photonics Reviews, EarlyView.Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...
