Cerebral haemodynamic responses to inspiratory muscle work
Experimental Physiology, EarlyView.Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...

Time‐Resolved SNOM via Phase‐Domain Sampling
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Time‐resolved scanning near‐field optical microscopy (tr‐SNOM) grants access to the dynamic dielectric function of monolayer and multilayer WS2, using visible wavelengths. In order to use a femtosecond laser with a repetition rate of 200 kHz, the signal is sampled and demodulated in the modulation phase domain, marking the first realization of tr‐SNOM ...

Nanophotonics, Volume 15, Issue 11, 13 June 2026.The fundamental index–bandgap trade‐off strictly limits materials for short‐wavelength nanophotonics. The van der Waals crystal CdPS3 emerges as a compelling alternative platform challenging this paradigm. Combining an exceptionally high refractive index approaching 3 with a broad mid‐infrared‐to‐ultraviolet transparency window, CdPS3 unlocks new ...
