Climatic niche divergence and high‐elevation adaptation promoted rapid diversification of Pimoa spiders in Pan‐Himalaya

The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across thr...

Analysis of mid-infrared spectral characteristics and recognition models of coal with different particle sizes

As a core energy source, the accurate identification of coal particle size is a critical part in the quality control of raw coal mining, separation and processing, storage and transportation, and quality upgrading. The differences in physical and chemical properties of coal with...
