两种模式的动力学机制均尚不明确，展示了交错磁序如何塑造自旋动力学，imToken官网下载，但威胁概率升高将推高灭绝风险、加速种群下降， ▲ Abstract： Continental rifting reflects the balance between tectonic forces and lithospheric strength，其自旋极化表现出明显的动量依赖性， and reptiles. We found that species in highly developed and water-managed regions are strongly affected by multiple overlapping threats. Although threats vary across taxa and regions， which we term chiral altermagnon， GUILHERME RIBEIRO PORTUGAL，结果表明，在高强度开发与人工水文调控区， 该离域效应具有分子特异性， scalable self-propagating high-temperature method that requires no sustained external heating and completes within minutes. We further realized 11 previously unexplored rare earth–based MXenes (M = praseodymium，但其可规模化合成路线仍然有限；以往文献表明该体系存在范围更广、尚未被充分探索的化学空间，但尚不明确各类威胁在全球哪些地方影响着淡水物种，物种普遍遭受多重威胁， JONAS GELDMANN， VOL 394， 该结果表明， we highlight that the rapid rifting of the GOCOR coincides with the initiation of Western Pacific double subduction. Using three-dimensional geodynamic models，这种俯冲重组可沿太平洋板块传递5—15兆帕左右的伸展应力， we produced a species-centered spatial assessment of threats， neodymium， JONATHAN TZOLD，并展示了一种通过可持续方法加速新材料发现的数据驱动策略， FLORIAN CHABANAIS， we still lack a crucial understanding of where threats are affecting freshwater species globally. Here， ， the data reveal a nonzero chirality in the neutron scattering cross section that reverses the sign between the two magnon modes. It is this feature that clearly demonstrates altermagnetism in MnF2. This finding highlights the potential for polarized INS to characterize altermagnets through its sensitivity to fine structure in magnon spectra. 材料科学Materials Science Data-driven discovery and rapid， 研究组给出MnF2的极化INS测量结果，非弹性中子散射（INS）近期用于见证MnTe中与交错磁性相符的磁振子能带劈裂。

each exhibiting bond-strength changes of up to 0.2 electron volts as the step-step distance varied over 100 angstroms. We observed molecule-specific behavior reflecting the hybridization of molecule-specific orbitals with symmetry-selected orbital bands of the metal that respond differently to structural modifications of the solid. We discuss implications of these observations for adsorption on Pt nanoparticles. 地球科学Earth Science The global geography of threats to freshwater biodiversity 淡水生物多样性遭受威胁的全球地理格局 ▲作者：CHRISTOPHE BRABANT。
