    Mining the Ocean Genome: Global Bioprospecting Expeditions and Genomic Extractivism on the Oceanic Frontier by Amedeo Policante, Erica Borg

    Published 2023-06-01
    “…We argue that emergent practices of ocean bioprospecting are sparking new ways of thinking, living and exploiting marine ecosystems as «genomic mines». We chart the recent history of genomic bioprospecting operations in the global ocean – focusing on the Sorcerer II expedition (2004-2006) and the Tara Oceans project (2009-2013) – and recount the rise of the «ocean genome» as an object of knowledge and a target of extractivist practices. …”

    Research on Feature Fusion Method of Mine Microseismic Signal Based on Unsupervised Learning by Rui Liu

    Published 2021-01-01
    “…The feature extraction of high-precision microseismic signals is an important prerequisite for multicategory recognition of microseismic signals, and it is also an important basis for intelligent sensing modules in smart mines. Aiming at the problem of unobvious feature extraction of multiclass mine microseismic signals, this paper is based on the unsupervised learning method in the deep learning method, combined with wavelet packet energy ratio and empirical modulus singular value decomposition, and proposes a method based on wavelet packet energy and empirical modulus singular value decomposition and proposes a method (M-W&E) based on wavelet packet energy and empirical modulus singular value decomposition. …”
