Prospective comparison of diagnostic accuracy of ultrasound, PET/CT and DW‐MRI for preoperative assessment of pelvic lymph nodes in cervical cancer patients: results of the CANNES trial

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 836-851, June 2026.
ABSTRACT Objective To determine whether ultrasound is non‐inferior to positron‐emission tomography/computed tomography (PET/CT) and diffusion‐weighted magnetic resonance imaging (DW‐MRI) in terms of overall diagnostic accuracy for the preoperative assessment of pelvic lymph‐node status in cervical cancer.

Rapid construction of insect–plant interaction networks via multiplexed long‐fragment DNA metabarcoding and NGS

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 6, Page 1896-1909, June 2026.
Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

基于MATLAB语言的静电场模拟电荷法分析

open access: yesDianci bileiqi, 2005
模拟电荷法是一种应用于静电场数值计算的有效方法。笔者应用模拟电荷法对球一板电极电场进行了计算,并用MATLAB语言编制了计算软件。计算结果表明,模拟电荷法原理简单,方法应用简洁,适用于求解各类电极较为规则和介质类别不多的电场问题。在实际计算中,应用MATLAB语言编制计算软件,在计算速度、精度以及图形生成上更加具有快捷、方便的特点。

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Energized? How German and Italian Party Actors Used Emotions in Energy Policy Narratives During the 2024 EU Elections

open access: yesEuropean Policy Analysis, Volume 12, Issue 3, Summer 2026.
ABSTRACT Energy transitions pose wicked policy problems that trigger strong public responses, shaped by how emotions are used in policy communication. Within the Narrative Policy Framework (NPF), policy actors leverage emotionally charged narratives to influence public opinion and policy processes.

滴灌条件下土壤平均含水率计算方法研究

open access: yesShuitu Baochi Xuebao, 2011
为寻找适合滴灌农田土壤平均含水率的计算方法,在裸地和大田试验研究的基础上选用单点平均、三点平均等5种方法分别计算了滴灌条件下平均土壤含水率,并以积分法为标准,对其他4种方法进行评价。结果表明,3点取样,采用面积加权平均法计算各层土壤的平均含水率,然后在垂直方向上采用积分中值定理求平均值的方法计算结果更接近真实值,误差最小,可利用该方法计算滴灌农田土壤平均含水率。
