面向工程应用的先进绝热压缩空气储能模型及先进㶲分析 [PDF]
全球能源互联网先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system，AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200 MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进分析。结果表明 ...

Using incentive payments to promote human–carnivore coexistence
Conservation Biology, EarlyView.Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

He jishu编码孔径成像广泛应用于低能量（<0.2 MeV）伽马成像领域，其在中高能段（0.2~5 MeV）的应用也在得到逐步拓展。为解决中高能伽马成像中串扰光斑、内散射增强所导致的成像性能恶化的问题，提出了基于推测首次反应位置的降噪方法。通过使用掺铈钆铝镓石榴石晶体（Cerium-doped Gadolinium Aluminum Gallium Garnet，GAGG：Ce）与硅光电倍增管（Silicon Photon Multiplier，SiPM）阵列耦合，并使用A5202采集模块读出 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

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.

Applications of Aqueous Metal Phthalocyanine Spectroscopic Probes in the Analysis of Biomacromolecules and Inorganic Anions [PDF]
, 2015 金属酞菁是一类化学性质稳定（耐热、耐酸、耐碱），较易合成的化合物。自Braun和Tehemiac获得第一个酞菁化合物以来，酞菁化合物由于其特殊的物理化学和光学性质而在化学和化工领域得到了广泛研究和应用。上世纪80年代开始，酞菁化合物在生物医学领域的应用也逐步得到开发应用。由于金属酞菁的吸收峰和荧光发射峰都在长波区段，可以避开绝大多数天然物质背景光的干扰，在生物化学分析中具有广泛的应用前景。本论文围绕水溶性金属酞菁作为分子探针在生物大分子和无机阴离子检测中的应用而展开 ...

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
