Abstract In this study, we employ the synthetic control method to evaluate the transmission of external shocks, taking COVID‐19 as an example, on the stock market in the Chinese hospitality and tourism industry, specifically in the catering, hotel, cultural landscape, natural landscape, and travel agency sectors. We find an increasingly negative causal

Exploring Time‐Domain Femtosecond Rotational Coherent Raman Scattering for Diagnostics
The diagnostic potential of femtosecond (fs) rotational coherent Raman scattering (RCRS) in the time domain is initially investigated. Experiments in air and pure nitrogen are reported, revealing the temperature sensitivity in the recorded fs‐RCRS temporal scans.

Integrated RF Photonic Front‐End Capable of Simultaneous Cascaded Functions
An integrated programmable RF photonic front‐end capable of simultaneous cascaded functions is demonstrated, including notch filtering with true time delay or phase shifting. This work shows the feasibility to achieve cascaded functions within an integrated RF photonic front‐end.

ABSTRACT Photoremovable protecting groups (PPGs) offer a straightforward solution for the temporary inactivation of biologically active substrates and their subsequent controlled release by light irradiation. Their relatively easy design and mode of application have made them useful tools for studying dynamic biological processes in vitro and in vivo ...

Abstract Purpose To enable contactless cardiac gating at 0.55T using pilot tone (PT). Current PT methods are unable to extract weak motions, including cardiac motion, at lower B0 field strengths (<1.5T). Methods We utilize high‐amplitude pilot tone with interference cancellation, termed HAPTIC.

Unmanned aerial vehicles (UAVs) are increasingly used for plant protection treatments. We describe the corresponding Swiss regulatory framework. We also summarize practical experiences gained from technical assessments performed within this framework, field use patterns and the results of field efficacy trials.
