基于最高频相位法和空间滤波法的二维模型的大地电磁静态校正

open access: yesDizhen xuebao, 2022
静态效应一直是影响大地电磁测深法精确性的主要原因之一。在相位校正法的基础上提出了一种更适用于电性变化较为平缓的地质情况的静态校正方法—最高频相位法,其核心是用需要校正测点两侧受静态效应影响较小测点的最高频视电阻率的算术平均值代替相位法递推公式中每个频点前一个频点的视电阻率值,以消除相位法中的误差积累。以二维模型的正反演为例,通过对比空间滤波法、相位法和最高频相位法对不同模型静态校正前后的正反演结果,证明了最高频相位法的有效性和优越性,同时表明,对于电阻率变化大并且静态位移严重的水平层状地层模型 ...

The association between daytime napping and risk of type 2 diabetes is modulated by inflammation and adiposity: Evidence from 435 342 UK‐Biobank participants 午睡与2型糖尿病风险之间的关联受到炎症和肥胖的调节:来自英国生物样本库(UK‐Biobank) 435 342名参与者的证据

open access: yesJournal of Diabetes, Volume 15, Issue 6, Page 496-507, June 2023., 2023
Highlights Using a large‐scale prospective population‐based cohort study, we found that a higher frequency of daytime napping is associated with an increased risk of incident type 2 diabetes (T2D), and such relations are modified by body fat percentage (BFP) and C‐reactive protein (CRP) levels.

Introducing a common taxonomy to support learning from failure in conservation

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Although some sectors have made significant progress in learning from failure, there is currently limited consensus on how a similar transition could best be achieved in conservation and what is required to facilitate this. One of the key enabling conditions for other sectors is a widely accepted and standardized classification system for ...

Systematic review of conservation interventions to promote voluntary behavior change

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Understanding human behavior is vital to developing interventions that effectively lead to proenvironmental behavior change, whether the focus is at the individual or societal level. However, interventions in many fields have historically lacked robust forms of evaluation, which makes it hard to be confident that these conservation ...

基于储能惯性响应的电网紧急频率控制方法 [PDF]

open access: yes全球能源互联网, 2023
针对特高压直流闭锁等原因造成的受端电网频率严重跌落问题,提出一种储能紧急频率控制策略。首先,建立储能参与紧急频率控制的数学模型。其次,对于大功率缺额后发电机组惯性响应不足问题,提出了改进的频率变化率(rate of change of frequency,RoCoF)下垂控制策略以提高储能的惯量支撑,根据储能比例分配系数实时调节储能虚拟惯性及下垂控制出力;惯性响应阶段以RoCoF下垂控制为主、虚拟惯性控制为辅,抑制系统频率变化率;结合频率调节需求和储能系统出力特点提出不同区域的调频策略 ...

Mitigating the effects of climate change on the nests of sea turtles with artificial irrigation

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract For sea turtles, like many oviparous species, increasing temperatures during development threaten to increase embryonic mortality, alter offspring quality, and potentially create suboptimal primary sex ratios. Various methods are being implemented to mitigate the effects of climate change on reproductive success, but these methods, such as ...

Rapid assessment of insect pollination services to inform decision‐making

open access: yesConservation Biology, Volume 36, Issue 4, August 2022., 2022
Abstract Pollinator declines have prompted efforts to assess how land‐use change affects insect pollinators and pollination services in agricultural landscapes. Yet many tools to measure insect pollination services require substantial landscape‐scale data and technical expertise.

A landscape‐scale framework to identify refugia from multiple stressors

open access: yesConservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract From a conservation perspective, quantifying potential refugial capacity has been predominantly focused on climate refugia, which is critical for maintaining the persistence of species and ecosystems. However, protection from other stressors, such as human‐induced changes in fire and hydrology, that cause habitat loss, degradation, and ...

Plant diversity ameliorates the evolutionary development of fungicide resistance in an agricultural ecosystem

open access: yesJournal of Applied Ecology, Volume 58, Issue 11, Page 2566-2578, November 2021., 2021
The development of fungicide resistance greatly threatens food security and ecological sustainability, and it is urgent need to develop agricultural practices which can ameliorate this problem. Our results show that potato crop with a genetic diversity is associated with a late blight pathogen of higher fungicide sensitivity and lower potential of ...

Healthy mistrust or complacent confidence? Civic vigilance in the reporting by leading newspapers on nuclear waste disposal in Finland and France

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 12, Issue 2, Page 130-157, June 2021., 2021
Abstract Trust and confidence have been identified as crucial for efforts at solving the conundrum of high‐level radioactive waste management (RWM). However, mistrust has its virtues, especially in the form of “civic vigilance”—healthy suspicion towards the powers that be.
