Expanded Farm Safety Net Payments Under the One Big Beautiful Bill Act

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The One Big Beautiful Bill Act (OBBBA) strengthens the agricultural risk coverage (ARC) and price loss coverage (PLC) programs by aligning program parameters more closely with recent market dynamics and allows for an expansion in program acres. This study projects the increases in ARC‐County and PLC payments for corn, soybeans, and wheat under

Evaluation of Greenhouse Gas Emissions and Sludge Characteristics in Typical AAO Process WWTPs in Taihu Lake Basin, China

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigated sludge characteristics and greenhouse gas (GHG) emission from 16 anaerobic‐anoxic‐oxic (AAO) process wastewater treatment plants (WWTPs), 11 municipal and 5 industrial WWTPs, located in the Taihu Lake Basin, China. Influent/effluent water quality, sludge properties, operational parameters, GHG emission patterns, and ...

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Reduction in the potential distribution of bee species in low latitudes under different climate change scenarios: conservation implications

open access: yesFrontiers in Ecology and Evolution
To quantify the climate-change impact on bees and guide conservation planning, we employed ecological niche modeling (ENM) driven by three representative concentration pathways (RCP 4.5, 6.0 and 8.5) and three general circulation models (CCSM4, HadGEM2 ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
