Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

Assessment of Electrical Resistance Sensors Sensitivity to Localized Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Are electrical resistance (ER) sensors reliable for localized corrosion detection? This study combines analytical modeling and experimental validation to show the vulnerability of ER sensors. The results demonstrate significant underestimation of the true corrosion depth of localized attacks depending on defect's geometry.

At‐Home Versus in‐Clinic Vital Capacity Measurement: Insights From the HEALEY ALS Platform Trial

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Respiratory weakness, typically monitored as vital capacity (VC), is a central feature of amyotrophic lateral sclerosis (ALS). VC is increasingly measured remotely in participants' homes, although in‐clinic assessment remains the standard.

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

open access: yesPeople and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.
