Estimating Ice Cover on the Great Lakes Using Seismic Ambient Noise
Abstract Lake ice impacts seismic noise on nearby seismometers, and therefore seismic observations can be used to monitor ice changes. However, the transfer function describing how lake‐microseism noise covaries with ice cover has not been quantified.

Abstract Accurate estimates of geothermal heat flow (GHF) are critical for predicting basal melting and identifying stable sites for ancient ice, yet GHF remains one of the least constrained boundary conditions for the Antarctic Ice Sheet. We evaluate nine published Antarctic GHF models against radar‐derived specularity content in the South Pole Basin (

Listening to the Atmosphere: Using Infrasound Observations to Infer Atmospheric Conditions
Abstract The stratosphere and mesosphere are important regions for the prediction of weather at the Earth's surface for medium‐ and long‐range forecasts. The availability of observations in these layers is lower than that of the troposphere, especially for the dynamics. While seeking new observational sources is important, there are existing infrasound

A near‐infrared organic photonic synapse with gold nanorods enhances light absorption and synaptic plasticity. When integrated into CNN and CSNN models, the device achieved accuracies of 98.57% and 92.01% on MNIST digit and dynamic gesture recognition tasks, respectively, demonstrating strong potential for intelligent vision and low‐power neuromorphic ...

Long‐Term Effects of Freeze–Thaw Events on Ecosystem Carbon Exchange
In this work, we utilized 24 long‐term (over 10 years) observed flux tower sites to analyze the impact of freeze–thaw events on net ecosystem carbon exchange (NEE) and ecosystem respiration (RE), and explored the resistance of ecosystem carbon exchange to freeze–thaw events.

ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,
