Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Journal of Analytical Psychology, EarlyView.Abstract This paper examines the concept of non‐understandable in psychotherapy, based on the author's own play therapy with a boy with mild ASD (autism spectrum disorder). ASD is considered to belong to an area beyond comprehension, as psychotherapy is often deemed ineffective for it.

Gaoya dianqi, 2023 在中国大容量的电力传输中，大多数采用三相五柱变压器，由于三相五柱变压器中零序磁路的存在导致直流入侵后磁路会发生严重饱和。为深入研究三相五柱变压器直流偏磁问题，搭建磁场有限元仿真模型，并配合变压器YNyn0联结的外电路方程进行耦合，通过在原边侧中性点输入不同大小的直流电流，首次模拟直流偏磁对三相五柱变压器负载下的影响。文中通过计算变压器原、副边电流和励磁电流波形与空载直流偏磁进行对比，并重点分析尖顶波处的变压器磁场分布，发现直流入侵对负载下副边绕组电流影响较小，原边电流随着直流电流增大发生一定程度的畸变 ...

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, EarlyView.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

基于小波变换的2013年芦山MS7.0地震前姑咱台钻孔应变异常时频分析
Dizhen xuebao, 2019 2013年4月20日芦山MS7.0地震前，四川省姑咱台四分量YRY-4型钻孔应变仪记录到显著的高频应变畸变信号。为了避免该畸变信号的高频部分在时频演化过程中发生频率混叠现象，同时便于讨论同一研究频段内震前更早记录到的弱应变异常时段与显著应变异常时段的相关性，本文对2012年1月1日至2013年4月20日期间姑咱台的钻孔应变数据进行了时频分析，并使用时域分段的小波变换方法，在局部时频谱中提取了应变异常，分析了各应变异常的频率相关性。结果表明，研究频段内存在两个峰值频率 ...

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

, 1999 对β′Ｃｕ－Ｚｎ合金的中温片状相（α１）在母相溶质原子贫化的区成分位移相变机制进行了热力学分析，结果表明，相变驱动力随贫化区溶质成分的减小而增加，贫化至确定成分时驱动力可在整个相变温区为负值，因此 ...
