Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Guangtongxin yanjiu, 2008 文章提出了一种基于差分演化算法的光纤布拉格光栅（FBG）参数重构技术。基于均匀FBG的目标反射谱,可利用差分演化算法寻找一组光栅参数,根据这组参数计算得到的反射谱与目标反射谱偏差最小,该组参数即为重构的光纤光栅参数。数值实例表明,差分演化算法计算效率高,结果精确,是一种实用的参数重构方法。

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

四川大学学报. 自然科学版, 2007 简要分析了H.264中的上下文自适应变长编码(CAVLC),并研究其采用的Golomb编码,提出了一种基于最优Golomb编码参数选择的改进算法.利用前一个需编码的数值的Golomb编码最优参数,对当前编码参数进行预测,使当前编码参数更逼进它的最优编码参数.试验结果表明:该算法较原有算法能更好的压缩残差数据,在量化参数QP较小时,能带来一定的压缩增益.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Gaoya dianqi, 2005 电力工程上不但需要知道互感线路的零序集总参数, 有时还需要知道分布参数。通过对线路端电气量的同步测量,可以计算得到线路的集总参数,继而可以分别对互感部分和非互感部分求取线路的分布参数。笔者首先给出了输电线路分布参数模型和集总参数模型之间的转化公式;在此基础上,提出了互感线路分布参数在线测量方法,并通过仿真试验对所提出的方法进行了验证。

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019
Conservation Biology, EarlyView.Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.
