Being able to detect changes in our visual environment reliably and quickly is important for many daily tasks. The motion silencing effect describes a decrease in the ability to detect feature changes for faster moving objects compared with stationary or slowly moving objects. One theory is that spatiotemporal receptive field properties in early vision might account for the silencing effect, suggesting that its origins are low-level visual processing.

Murphy and Hall (2024) present two criticisms of our review of construct validity evidence reporting practices for the Reading the Mind in the Eyes Test (RMET; Higgins, Kaplan, Deschrijver, & Ross, 2024). Namely, they argue that we conflated poor reporting practices with poor validity and that our conclusions about the validity of RMET scores relied too heavily on structural validity evidence at the cost of external validity evidence. Moreover, they argue that the existing external and structural validity evidence indicates that RMET scores are generally valid for assessing emotion recognition ability.

Mantle oxidation by sulfur drives the formation of giant gold deposits in subduction zones.

Proc Natl Acad Sci U S A

December 2024

Frontiers Science Center for Deep-time Digital Earth, State Key Laboratory of Geological Processes and Mineral Resources, School of Earth Sciences and Resources, China University of Geosciences, Beijing 100083, China.

Oxidation of the sub-arc mantle driven by slab-derived fluids has been hypothesized to contribute to the formation of gold deposits in magmatic arc environments that host the majority of metal resources on Earth. However, the mechanism by which the infiltration of slab-derived fluids into the mantle wedge changes its oxidation state and affects Au enrichment remains poorly understood. Here, we present the results of a numerical model that demonstrates that slab-derived fluids introduce large amounts of sulfate (S) into the overlying mantle wedge that increase its oxygen fugacity by up to 3 to 4 log units relative to the pristine mantle.

Ultrathin BIC Metasurfaces Based on Ultra-Low-Loss SbSe Phase-Change Material.

Nano Lett

December 2024

School of Physics and Astronomy, Faculty of Science, Monash University, Melbourne, Victoria 3800, Australia.

Ultrathin and low-loss phase-change materials (PCMs) are highly valued for their fast and effective phase transitions and applications in reconfigurable photonic chips, metasurfaces, optical modulators, sensors, photonic memories, and neuromorphic computing. However, conventional PCMs mostly suffer from high intrinsic losses in the near-infrared (NIR) region, limiting their potential for high quality factor (-factor) resonant metasurfaces. Here we present the design and fabrication of tunable bound states in the continuum (BIC) metasurfaces using the ultra-low-loss PCM SbSe.
