Recorded displacements in a landslide slope due to regional and teleseismic earthquakes [PDF]

open access: yes, 2015
Regional and teleseismic earthquakes can induce displacements along joints in a landslideinvolved rocky slope in Central Italy. The rarity of these effects is due to specific physical properties of the seismic signals associated with: (i) the energy ...

Thermal conductivity of sedimentary rocks in the Sichuan basin, Southwest China [PDF]

open access: yesEnergy Exploration & Exploitation, 2018
The optical scanning method was adopted to measure the thermal conductivities of 418 drill-core samples from 30 boreholes in Sichuan basin. All the measured thermal conductivities mainly range from 2.00 to 4.00 W/m K with a mean of 2.85 W/m K. For clastic rocks, the mean thermal conductivities of sandstone, mudstone, and shale are 3.06 ± 0.73, 2.57 ...

DNA Barcoding Reveals Cryptic Diversity and Informs Conservation Priorities in Chinese Firmiana Species (Malvaceae) Using Genome Skimming Data DNA条形码揭示中国梧桐属 (锦葵科) 隐存多样性及保护优先级:来自基因组浅层测序数据的证据

open access: yesIntegrative Conservation, EarlyView.
Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...
