Light-matter interaction in the strong coupling regime enables light control at the single-photon level. We develop numerical method and analytical expressions to calculate the decay kinetics of an initially excited two-level quantum emitter in dielectric nanostructure and single-mode cavity, respectively. We use these methods to discover the dual effects of disorder on the stronglycoupled system composed of a single quantum dot and a photonic crystal L3 cavity. The quality factor is sensitive to disorder,while the g factor and vacuum Rabi splitting are robust against disorder. A small amount of disorder may either decrease or increase the light localization and the light-matter interaction. Our methods offer flexible and efficient theoretical tools for the investigation of light-matter interaction, especially cavity quantum electrodynamics. Our findings significantly lower the requirements for optimization effort and fabrication precision and open up many promising practical possibilities.

Investigating the impacts of soil conversion on soil organic carbon(OC) content and its fractions within soil aggregates is essential for defining better strategies to improve soil structure and OC sequestration in terrestrial ecosystems. However, the consequences of soil conversion from paddy soil to upland soil for soil aggregates and intra-aggregate OC pools are poorly understood. Therefore, the objective of this study was to quantify the effects of soil conversion on soil aggregate and intra-aggregate OC pool distributions. Four typical rice-producing areas were chosen in North and South China, paired soil samples(upland soil converted from paddy soil more than ten years ago vs. adjacent paddy soil) were collected(0–20 cm) with three replicates in each area. A set of core parameters(OC preservation capacity, aggregate carbon(C) turnover, and biological activity index) were evaluated to assess the responses of intra-aggregate OC turnover to soil conversion. Results showed that soil conversion from paddy soil to upland soil significantly improved the formation of macro-aggregates and increased aggregate stability. It also notably decreased soil intra-aggregate OC pools, including easily oxidized OCa(EOCa), particulate OCa(POCa), and mineral-bound(MOCa) OC, and the sensitivity of aggregate-associated OC pools to soil conversion followed the order: EOCa(average reduction of 21.1%) > MOCa(average reduction of 15.4%) > POCa(average reduction of 14.8%). The potentially mineralizable C(C_(0)) was significantly higher in upland soil than in paddy soil, but the corresponding decay constant(k) was lower in upland soil than in paddy soil. Random forest model and partial correlation analysis showed that EOCa and pH were the important nutrient and physicochemical factors impacting k of C mineralization in paddy soil,while MOCa and C-related enzyme(β-D-cellobiohydrolase) were identified as the key factors in upland soil. In conclusion, this study evidenced that soil conversion

Mineralized tissue regeneration is an important and challenging part of the field of tissue engineering and regeneration. At present,autograft harvest procedures may cause secondary trauma to patients, while bone scaffold materials lack osteogenic activity, resulting in a limited application. Loaded with osteogenic induction growth factor can improve the osteoinductive performance of bone graft,but the explosive release of growth factor may also cause side effects. In this study, we innovatively used platelet-rich fibrin(PRF)-modified bone scaffolds(Bio-Oss?) to replace autograft, and used cytokine(BMP-2) to enhance osteogenesis. Encouragingly, this mixture, which we named "Autograft Mimic(AGM)", has multiple functions and advantages.(1) The fiber network provided by PRF binds the entire bone scaffold together, thereby shaping the bone grafts and maintaining the space of the defect area.(2) The sustained release of BMP-2 from bone graft promoted bone regeneration continuously.(3) AGM recruited bone marrow mesenchymal stem cells(BMSCs) and promote their proliferation, migration, and osteogenic differentiation. Thus, AGM developed in this study can improve osteogenesis, and provide new guidance for the development of clinical bone grafts.

将五光子晶体单模波导平行、邻近放置构成定向耦合器,依据自映像原理,数值分析了输入光场对称入射时,该系统中光的传播行为。基于此结构,设计了1×3光分束器,其器件长度可短至14.26μm。仅仅通过对称地改变耦合区中两个介质柱的有效折射率,使光场在横向发生重新分布,便可实现输出能量的均分或自由分配。通过非对称地改变耦合区中的一个介质柱,可实现3个输出端的输出能量的自由分配。该光分束器具有微小尺寸和各输出端输出能量的比例可自由调制的特点,在未来集成光回路中具有广泛的应用价值。

静止气象卫星产品在天气监测和气候变化应用中发挥着重要作用。受天气状况影响,静止气象卫星地表温度经常存在缺失现象,严重影响着地表温度产品的深入应用。在地表温度缺失值的时间维重建过程中,现有研究大多是比较了不同时间维重建方法的精度,而有关数据缺失时段对模型能否有效重建的影响研究较少。本文以黑河流域为例,基于INA08温度日循环模型,通过模拟实验分析夏季FY-4A(风云4号A星)AGRI(Advanced Geostationary orbit Radiation Imager,先进的静止轨道辐射成像仪)LST(Land Surface Temperature,陆地表面温度)数据缺失对重建结果精度的影响,提出了不同缺失时段的数值替换方案,并采用真实数据对理论实验分析结果进行验证。结果表明:(1)缺失第二时段(13—15时)对重建结果的影响可忽略不计,缺失第五时段(次日0—6时)对重建结果影响最大;(2)随着缺失时段的增多,参与INA08模型拟合的遥感反演原始值减少,精度也有所下降;(3)模拟实验总结的缺失时段数值替换方案对INA08模型重建FY-4AAGRI LST具有一定指导作用,缺失时段某个时刻被替换为其他时刻地表温度后,能够显著提高缺失数据重建精度。
