Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Apex predators exploit advantageous snow conditions across hunting modes
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

CHINESE UNIVERSITIES AS URBAN DEVELOPERS: The Tale of Two Innovation Complexes in Nanjing, China
Abstract Chinese universities are important but undertheorized players in the production of urban built environments. Most work focuses on purpose‐built university towns, neglecting the redevelopment of underutilized downtown campuses. Therefore, this article considers how two publicly funded universities in Nanjing attempted to establish ‘innovation ...

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt
Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.
