Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Insights for conservation from the Ecological Knowledge Games project

open access: yesConservation 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 ...

基于可行模型集合方法的多模型切换控制

open access: yes, 2004
对含参数跳变的一类具有有界干扰的多输入多输出系统,为改善系统的瞬态响应性能,采用由多个固定模型和两个自适应模型组成的多模型,并引入切换指标函数构成多模型切换控制器.为克服多模型方法计算量大的缺点,采用可行模型集合方法,给出了可行模型应满足的必要条件.应用这一必要条件,对系统的多个模型进行检验,可快速缩小模型可行集合的范围,再通过切换指标函数,在可行模型集合中选择正确的控制器,从而在不降低系统响应性能的前提下 ...

Role of funders in embedding tests in conservation practice

open access: yesConservation Biology, EarlyView.
Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

STZ诱导C57BL小鼠T1DM模型优化的研究

open access: yesZhongguo shiyan zhenduanxue, 2007
目的探索制备T1DM小鼠模型优化条件,为研究T1DM病因及发病机理提供理想的动物模型。方法分别应用不同剂量、不同性别小鼠以小剂量、多次注射链脲佐菌素方法(multiple low dose of streptozotocin,MLDS)制备T1DM小鼠糖尿病模型,动态监测小鼠血糖水平、体重的变化,比较不同方法糖尿病模型成功率与糖尿病小鼠死亡率。结果MLDS诱导雌性C57BL小鼠T1DM模型STZ小剂量组模型成功率为0,死亡率为22.06%。STZ大剂量组模型成功率为57.14%,死亡率为28.56 ...

"fordi før så skreiv æ Å-G". En studie om andreklassingers valg av stavemåter.

open access: yes, 2023
The purpose of this master's thesis has been to look at the choices students in Year 2 make when spelling words. The students participating in this research are in the transition between phonological and orthographic writing, and the study will focus on how these students adopt different spelling strategies. The assignment's data material is taken from

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

雷电冲击下换流变压器的缩比模型设计与测试

open access: yesGaoya dianqi, 2019
换流变压器进行雷电冲击耐压试验研究周期长、代价高,而利用缩比模型进行试验研究具有良好的经济性,且利于试验数据的获取,并可与仿真结果进行对比分析。为设计与原模型电气特性一致的缩比模型,本文推导了雷电冲击下变压器的缩比公式,设计了缩比模型,对缩比模型和原模型在相似激励下的电场和磁场分布进行了仿真对比,并利用多导体传输线模型计算了缩比模型与原模型在雷电冲击下的绕组电压波形,原模型与缩比模型误差在5%以内。对缩比模型进行了绕组分布电压测量,结果表明,引出线结构会影响绕组电气特性,需进一步研究修正方法。
