Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Transition metal compounds and alloys: A first-principles investigation [PDF]
, 2015 含过渡金属的化合物与合金在数据存储、光催化和能量存储与转换等领域有重要的应用，主要得益于其特定的电子结构、力学性能等性质。本论文利用基于密度泛函理论的第一性原理计算方法，选取特定的研究体系，系统地探索了过渡金属化合物与合金的电子结构（第三章）、内部原子扩散（第四章）、力学性能（第五章）以及压力与温度对其性质的影响（第六章）。 为了研究缺陷和掺杂对过渡金属氧化物电子结构的调制，我们以SrZrO3为研究对象，首先研究了内部含有有序氧空位和部分无序氧空位体系的电子结构。计算结果表明 ...

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

Theoritical investigations of phase stability, elastic and thermodynamic properties of γ’ phase in Co-X (X:Al, V) based superalloys [PDF]
, 2016 Ni基高温合金是航空航天领域应用最广的高温材料。随着国防科技的发展，新一代的航空航天飞机对发动机涡轮叶片材料的承温能力提出更高的要求。然而Ni基高温合金受熔点的限制，其服役温度很难进一步提高。寻找下一代高温合金成为国内外研究机构的关注焦点。最近，研究者们陆续在Co-Al基和Co-V基合金中发现与Ni3Al类似的γ’析出强化相，由此掀起了新型钴基高温合金的研究热潮。作为新型Co基高温合金中的关键强化相，γ’相的结构稳定性和弹性性质直接决定了Co基高温合金的综合力学性能 ...

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.
