Automating the analysis of public saliency and attitudes toward biodiversity from digital media

open access: yesConservation Biology, EarlyView.
Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Automatic vibration fault detection of coal mine explosion-proof electrical equipment based on One-Class Support Vector Machine [PDF]

open access: yes
The vibration generated by explosion-proof electrical equipment in coal mines during operation can compromise its mechanical integrity, leading to fastener loosening, component wear, and changes in the structure and vibration modes of the equipment. This

基于逐次变分模态分解的飞轮-火电一次调频控制策略 [PDF]

open access: yes全球能源互联网
随着新型电力系统的大力建设与推广,火电机组面临的调频压力增大,提出一种逐次变分模态分解的飞轮-火电一次调频控制策略。首先,以飞轮储能和火电机组为研究对象,建立考虑新能源占比的飞轮-火电一次调频模型;其次,将一次调频功率指令利用逐次变分模态方法分解,由火电机组响应分解后的低频功率指令,同时设计飞轮储能下垂优化控制方法,实现飞轮储能与火电机组响应频率变化的协同控制;最后在不同工况下仿真验证,结果表明所提策略可有效避免火电机组一次调频时的频繁出力,减小火电机组响应频率变化时的调控要求 ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

基于噪声敏感先验的改进VMD惯导异构信号降噪

open access: yesZhendong Ceshi yu Zhenduan
针对煤矿锚杆钻车姿态估计中惯性导航的多源噪声,提出一种基于噪声敏感先验的改进变分模态分解(variational mode decomposition,简称VMD)惯导异构信号降噪方法。首先,利用加速度和角速度时频域参数特性变化,探究捷联惯导异构信号的噪声敏感差异和多源噪声作用规律;其次,根据异构信号噪声敏感先验和最大峭度变化趋势,构建双分解层,并通过能量波动模型监测在不同分解层下模态分量的能量变化,避免参数固定造成的过分解和欠分解问题,实现对惯导异构信号同步VMD分解;然后,根据皮尔逊相关系数 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Research on advocacy coalitions suggests that belief homophily—the tendency of actors to coordinate based on shared policy beliefs—drives coalition formation. However, coalition opportunity structures, which are shaped by institutional contexts, may influence the extent to which belief homophily matters.

A Review of UWB Radar Detection of Respiration and Heartbeat Signals in Different Scenarios [PDF]

open access: yes
Due to their many advantages, such as simple structure, low transmission power, strong penetration capability, high resolution, and high transmission speed, UWB (Ultra-WideBand) radars have been widely used for detecting life information in various ...

The Five‐Thread Model & Academic Policy Entrepreneurs: From the White Australia Policy to Multicultural Australia

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Why did Australia go from the White Australia Policy, which excluded non‐whites, to institutionalizing multiculturalism policy in the 1970s? This question defies traditional political ideologies of the major political parties, which had long supported the White Australia Policy. This article is a rare empirical demonstration of the Five‐Thread
