New Phytologist, EarlyView.Whole‐genome duplication enhances gray mold resistance in autotetraploid Fragaria nilgerrensis through coordinated gene‐dosage effects, DNA methylation remodeling, and cell‐type‐specific transcriptional reprogramming. Summary Whole‐genome duplication (WGD) triggers genetic and epigenetic remodeling that confers stress adaptation in plants, but how ...

Journal of Critical Infrastructure Policy, Volume 8, Issue 1, Spring/Summer 2027.ABSTRACT Epistemic orphaning, responsibility drift, loss of institutional memory, and non‐stationarity are not new problems in infrastructure governance—they have accompanied long‐life infrastructure throughout its history. What artificial intelligence changes is not the existence of these problems but their scale, opacity, and the structural ...

, 2007 我国强制执行机构的改革在很大程度上受制于关于执行权性质的理论探讨和实践尝试。由于对执行权和执行机构属性定位的误差,我国法院执行机构的改革出现了一定的偏差。理性地认识强制执行权并在法院现有体制下纯化执行庭的裁判职能,将执行权中行政属性职权交由法院司法警察行使 ...

How e‐Government Shapes Citizen Engagement in Participatory Budgeting
Latin American Policy, Volume 17, Issue 4, December 2026.ABSTRACT E‐government has been widely adopted to enhance citizen participation and improve transparency in public decision making. Yet, its effects on engagement remain context‐dependent and insufficiently theorized, particularly in Global South settings.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)

Shuitu Baochi Xuebao, 2006 根据18年的长期定位试验，探讨了不同施肥处理对黄土丘陵区栗褐土土壤容重、土壤结构、孔隙性、水分物理性质以及对土壤有机质和土壤氮，磷含量的影响。结果表明，长期施用有机肥有利于保持和改善土壤孔隙状况，促进水稳性团聚体的形成，提高土壤的透水性和持水能力。单施化肥与不施肥相比，土壤物理性质有所改善，但与初始值比较则变劣。有机肥与化肥配合施用，可减轻化肥对土壤物理性质的不良影响。长期不施肥土壤物理性质有恶化趋势。单施有机肥和有机无机肥配合施用可显著提高土壤有机质和氮、磷含量，有机无机肥配合施用效果更明显 ...
