What is an online political advert? An interrogation of conceptual challenges in the formation of digital policy response

open access: yesPolicy &Internet, Volume 15, Issue 4, Page 713-730, December 2023., 2023
Abstract Despite British and European policymakers' quest to regulate online political advertising, it is not clear what exactly constitutes an online political advert. As with many areas of digital governance, it is therefore necessary to impose definitional criteria, yet the process of doing so is by no means straightforward.

Fossil image identification using deep learning ensembles of data augmented multiviews

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 12, Page 3020-3034, December 2023., 2023
Abstract Identification of fossil species is crucial to evolutionary studies. Recent advances from deep learning have shown promising prospects in fossil image identification. However, the quantity and quality of labelled fossil images are often limited due to fossil preservation, conditioned sampling and expensive and inconsistent label annotation by ...

Spatio‐temporal dynamics of human−elephant conflict in a valley of pineapple plantations 菠萝种植园中的人象冲突时空动态

open access: yesIntegrative Conservation, Volume 2, Issue 2, Page 95-107, June 2023., 2023
This is a study of the spatiotemporal patterns of Human−Elephant conflict in a community area adjacent to Kuiburi National Park, southern Thailand. We examined temporal and spatial patterns of elephant crop raiding by assessing the locations of elephant raids in conjunction with environmental factors along with crop characteristics and crop ...

A systematic review of animal personality in conservation science

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer‐reviewed literature relating to conservation science and animal personality.

An Improved Multi‐Task Pointwise Network for Segmentation of Building Roofs in Airborne Laser Scanning Point Clouds

open access: yesThe Photogrammetric Record, Volume 37, Issue 179, Page 260-284, September 2022., 2022
Zhang et al. propose an improved multi‐task pointwise network to simultaneously segment instances (that is, individual roof planes) and semantics (that is, groups of roof planes with similar geometric shapes) in point clouds. A new roof data‐set (called RoofNTNU) is established by taking standard airborne laser scanning (ALS) point clouds as training ...

Ignoring non‐English‐language studies may bias ecological meta‐analyses

open access: yesEcology and Evolution, Volume 10, Issue 13, Page 6373-6384, July 2020., 2020
Ignoring non‐English‐language literature may bias outcomes of ecological meta‐analyses, due to systematic differences in effect sizes between studies published in English and non‐English languages. Abstract Meta‐analysis plays a crucial role in syntheses of quantitative evidence in ecology and biodiversity conservation.

A network approach to prioritize conservation efforts for migratory birds

open access: yesConservation Biology, Volume 34, Issue 2, Page 416-426, April 2020., 2020
Abstract Habitat loss can trigger migration network collapse by isolating migratory bird breeding grounds from nonbreeding grounds. Theoretically, habitat loss can have vastly different impacts depending on the site's importance within the migratory corridor.

基于改进集合模态分解的真空断路器分合闸线圈电流特征值提取

open access: yesGaoya dianqi, 2020
断路器动作时,分合闸线圈电流特征能够反映断路器操动机构或者二次回路的运行状态,分析分合闸线圈电流特性,对断路器故障诊断具有重要意义。文中提出了基于改进集合模态分解(MEEMD)的分合闸线圈电流特征值提取方法。该方法使用MEEMD分解分合闸线圈电流信号,得到经验模态分量(IMF),然后对分量求其瞬时频率,利用频率谱中峰值所对应坐标表征原始信号的特征值。实验结果表明,该方法能正确有效提取分合闸线圈电流特征值。
