Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

Laser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

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 ...

Improved Corrosion Resistance of a Micro‐Alloyed Carbon Steel Assessed by Multi‐Element Electrical Resistance Probes and Coupons in Natural Seawater and Soil

Materials and Corrosion, EarlyView.
Multi‐element electrical resistance probes fabricated from industrial carbon steels enable real‐time corrosion monitoring in natural seawater and soil. A micro‐alloyed grade (AMLoCor) demonstrates up to 2.4 times improved uniform corrosion resistance over conventional S355 GP steel.

Design and performance of a capacitor‐based burn‐through monitor for high‐power X‐ray beams at XFEL facilities

Journal of Synchrotron Radiation, EarlyView.
We present the results of testing 92 prototypes of a capacitor‐based burn‐through monitor at the LCLS XCS and XPP endstations. We quantify the beam energy density thresholds required to induce a detectable high‐voltage electrical short prior to complete burn‐through and demonstrate the reliability of this scalable, low‐cost solution for machine and ...
