Modeling mammal response to fire based on species’ traits
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Fire has shaped ecological communities worldwide for millennia, but impacts of fire on individual species are often poorly understood. We performed a meta‐analysis to predict which traits, habitat, or study variables and fire characteristics affect how mammal species respond to fire.

Spatial mismatch between wild bee diversity hotspots and protected areas
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Wild bees are critical for multiple ecosystem functions but are currently threatened. Understanding the determinants of the spatial distribution of wild bee diversity is a major research gap for their conservation. We modeled wild bee α and β taxonomic and functional diversity in Switzerland to uncover countrywide diversity patterns and ...

MsaH2A.W is identified response to salt tolerance in Miscanthus sacchariflorus
GCB Bioenergy, Volume 15, Issue 8, Page 1058-1073, August 2023., 2023 To study the underlying genetic basis of Miscanthus adaptation to salt stress, the transcriptome variations of Miscanthus sinensis, Miscanthus sacchariflorus and their hybrid were analysed using RNA‐seq technology under salt treatment. According to the expression pattern of known salt‐tolerant genes, a histone variant gene MsaH2AW of M.

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

Using porous metals to enhance heat transfer in phase change materials (PCMs) [PDF]
, 2011 Heat transfer enhancement mechanism of Phase Change Materials (PCMs) by high-porosity metal foams was investigated in this study. The Darcy-Brinkman-Forchheimer modified flow model was employed in the numerical simulations to consider the non-Darcy ...

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

Research of Resonator-sound-generator Atomizing Nozzle [PDF]
, 2015 喷嘴技术的应用范围几乎包含所有工业领域、农业生产、交通运输以及人们的日常生活。作为必备组件在燃烧装置上的应用尤为重要。以往对于新型的流体动力式超声波雾化喷嘴研究表明：这类喷嘴的雾化粒径小（小于50μm）且分布均匀性好，对实现低氧燃烧、减少烟气中烟尘和氮氧污染物的排放有实质性的意义。因此本文以谐振腔式声能雾化喷嘴为研究对象，通过设计结构，利用FLUENT软件对其流场、声场以及雾化性能进行多参数的数值模拟，通过雾化性能的变化规律分析了其雾化机理。 研究首先基于哈特曼发声哨的原理设计了谐振腔式声能雾化喷嘴 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

Studies of the PPDF Chemical Reaction Rate Model for the Numerical Simulation of Nitrogen Oxides [PDF]
, 2016 本文在目前应用广泛的湍流燃烧模拟方法PPDF，即预设概率密度函数的基础上，以混合分数和温度为变量，同时引入时间尺度的考虑，提出了一个NOx计算模型——PPDF化学反应速率模型。在该模型的理论基础上，使用CHEMKIN软件的SENKIN模块，以详细的化学反应机理计算NO的生成速率，并将计算结果拟合建立成数据库。 使用该模型在STAR-CD中计算了三组湍流非预混射流火焰：H2、H2/CO/N2和CH4/H2/N2射流火焰，并与Sandia实验室公布的实验数据进行比较 ...
