Assessing limits of sustainable seed harvest in wild plant populations
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

Politics &Policy, Volume 53, Issue 5, October 2025.ABSTRACT This study examines how military expenditure moderates the negative effect of terrorism on economic complexity in Europe. Terrorism is proxied by terrorism‐related incidences, fatalities, injuries, and hostages. The study utilizes a panel dataset comprising 33 European economies spanning the period 2011–2022.

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

World Affairs, Volume 187, Issue 3, Page 317-331, Fall 2024.Abstract This research investigates how enhancing remittances affects total factor productivity (TFP) dynamics in Sub‐Saharan Africa. The Generalized Method of Moments empirical strategy is adopted for this study and the engaged TFP dynamics are: TFP, real TFP, welfare TFP, and real welfare TFP.

四川大学学报. 自然科学版, 2011 提出了一种新的用于均匀线阵的四阶累积量DOA估计算法.针对传统MUSIC-like算法中四阶累积量矩阵存在大量冗余信息的情况,本文算法提出了一种新的四阶累积量矩阵构造方法.用该方法构造的四阶累积量矩阵在保证阵列扩展性能的同时,去掉了MUSIC-like算法中四阶累积量矩阵的冗余信息,降低了矩阵的阶数.与MUSIC-like算法相比,本文算法的运算复杂度显著降低,但仍保持了同等的估计性能.实验仿真表明了提出方法的有效性.

World Affairs, Volume 187, Issue 1, Page 63-77, Spring 2024.Abstract The purpose of this study is to assess how some governance dynamics, such as political stability and the rule of law, moderate the incidence of some macroeconomic factors (i.e., domestic investment and trade openness) on tourism development. The focus of this study is on 47 countries in sub‐Saharan Africa with data from 2002 to 2018, and the ...

Politics &Policy, Volume 52, Issue 1, Page 118-139, February 2024.Abstract Motivated by the difficulty of ensuring gender equality and the chaotic state of democracy, we analyze the effects of gender political inclusion and democracy on environmental policy performance. The study uses a panel of 45 African countries over the period 2012–2018 and employs the method of moments by quantile regression.

四川大学学报. 自然科学版, 2013 针对衰减-时延混合模型,提出一种改进的欠定语音盲分离算法.第一步根据独立语音源在时频域上的稀疏性,用势函数法分别聚类估计衰减矩阵和时延矩阵,然后配对以确定各声源混合矩阵.第二步由估计的混合矩阵,采用改进最短路径法恢复出目标语音.为了减少计算量,设置门限对能量较小的时频点直接置零处理,在衰减矩阵和时延矩阵聚类估计时采用了分段聚类算法.仿真实验表明本文算法分离出的语音和源语音相似系数达0.96,0.97,0.93,信噪比达12.66dB,12.86dB,8.87dB,且有效减少了计算量 ...
