本发明提供了一种当一级磁相变材料作为磁致冷材料应用时拓展该材料制冷温区的方法,将该一级磁相变材料经零磁场冷却后进行升温,在升温过程中仅在相变温区磁性和电阻发生相变,具有磁熵变△S,而在其它温区磁性和电阻不发生变化,无磁熵变;同时,将该材料经非零磁场冷却后进行升温,由于捕获相的出现在升温过程中还在其它温区发生磁性和电阻的变化,具有磁熵变化△S’;因此,当该材料作为磁制冷材料应用时,通过对该材料施加磁场,在该磁场条件下降温冷却,使其铁磁性、低电阻的奥氏体相捕获到低温,即可实现低温区的巨磁热效应 ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Ten rules for using evidence to guide ecosystem restoration
These 10 rules provide a guidance framework to put into action the best available evidence, ensuring that restoration benefits people and nature. We highlight the importance of knowledge brokering systems in this process, effectively informed and empowered to fulfil their emerging role across existing institutions and new ones dedicated to Science ...

Cutting Through the State: Examining Voter Alignment With Milei's Agenda and His Chainsaw Plan
ABSTRACT Argentina's political landscape experienced a major shift with the unexpected election of Javier Milei as President. Known for his radical right‐wing stance, Milei has pledged to drastically minimize the state's role, proposing a public spending cut of 14% of the gross domestic product.

Out of Sight, Out of Mind? The Impact of Issue Proximity on Policy Choice at the Individual Level
ABSTRACT Scholars have extensively studied the link between issue definition and policy choice. However, empirical evidence on the role of issue proximity on policy support at the individual level remains scarce. The study draws on policy and management literatures to examine whether framing an issue as more or less spatially proximate to an individual
