High‐resolution optical design of the sub‐meV ARPES beamline at the Ultrafast Transient Experimental Facility

Journal of Synchrotron Radiation, EarlyView.
The Ultrafast Transient Experimental Facility at Chongqing University is developing an advanced ARPES beamline capable of 0.4 meV energy resolution within the 10–40 eV photon energy range, featuring photon flux over 1012 photons s−1, tunable polarization and ultra‐low temperatures below 1.5 K.

New opportunities for grassland species in warming temperate winters

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperate winters are getting warmer, the length of the growing season is increasing and mid‐winter fluctuations of warm and freezing temperatures are more frequent. Although typically winter dormant, some herbaceous perennials can maintain or grow green leaves during ...

Three‐dimensional morphological analysis of Chang'e‐5 lunar soil using deep learning‐automated segmentation on computed tomography scans

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based

Lessons from the void: What Boltzmann brains teach

Analytic Philosophy, EarlyView.
Abstract Some physical theories predict that almost all brains in the universe are Boltzmann brains, that is, short‐lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis ...

Physical and chemical characterization of recycled glass sand for environmental restoration

Restoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.
