The Inner Mongolia grassland has been facing critical degradation. To combat this issue, China has launched a series of ecological restoration programs since the early 2000s to promote the recovery of degraded grasslands (e.g., the Beijing–Tianjin Wind/Sand Source Control Program, the Grazing Withdrawal Project, and the Ecological Compensation Policy). However, the long-term effects of these measures on the recovery of the Inner Mongolia grassland still need further evaluation. To quantitatively assess the grassland degradation status and dynamics, we utilized long-term remote sensing datasets (GIMMS NDVI and MODIS NDVI) from 1982 to 2020 to calculate the fractional vegetation cover (FVC, the ratio of vegetation canopy's vertical projection area to the unit area) and grassland degradation index (GDI, the ratio of average FVC during peak growing season to historical optimum FVC). Results showed that across the study region, the average FVC was 42% over the past four decades, with degraded grassland (GDI < 0.9) accounting for 84.6% of the total area. Noteworthy spatial differences were observed. Specifically, study region to the west of 115°E had an average FVC of 20.7% with 98.2% areas exhibiting a degraded state. By contrast, study region to the east had an average FVC of 57.7% with 68.5% areas experiencing degradation. Over time, the proportion of degraded grassland generally decreased, particularly in the past two decades. However, approximately 3/4 of the grassland remained degraded in the last decade (2011–2020). Although degraded grassland is recovering, grassland degradation remains serious, especially in the west of 115°E, where 80.8% of the grassland was moderately and severely degraded (GDI < 0.6) in the last decade. Our findings suggest that while the implementation of ecological protection measures in Inner Mongolia has slowed down grassland degradation, the persisting degradation underscores the necessity of region-specific grassland protection and restoration.

内蒙古草原已面临严重退化。为了解决这一问题，自21世纪初以来，中国启动了一系列生态恢复计划，以促进退化草原的恢复（如京津风沙源治理计划、退牧工程和生态补偿政策）。但这些措施对内蒙古草原恢复的长期效果还有待进一步评价。为了定量评价草地退化状况和动态，利用1982 ~ 2020年的长期遥感数据（GIMMS NDVI和MODIS NDVI），计算了植被覆盖度（FVC，植被冠层垂直投影面积与单位面积之比）和草地退化指数（GDI，植被生长旺季平均覆盖度与历史最优覆盖度之比）。结果表明：近40年来，研究区平均植被覆盖度为42%，退化草地（GDI < 0.9）占总面积的84.6%；观察到显著的空间差异。其中，东经115°以西研究区平均植被覆盖度为20.7%，98.2%的区域处于退化状态。东部研究区平均植被覆盖度为57.7%，退化面积为68.5%。随着时间的推移，退化草地的比例普遍下降，特别是在过去二十年中。然而，在过去十年（2011-2020年）中，约有3/4的草地仍处于退化状态。虽然退化的草地正在恢复，但退化程度仍然严重，特别是在115°E以西，近10年来80.8%的草地处于中度和重度退化状态（GDI < 0.6）。研究结果表明，虽然内蒙古生态保护措施的实施减缓了草原退化，但持续的退化凸显了因地施治草地保护与恢复的必要性。

Organophosphate esters (OPEs) are a class of chemicals of emerging concern. However, little is known about the environmental behavior, transformation and ecological risk of OPEs in mid-latitude glacial environments. This study investigated the concentration and composition characteristics of organophosphate triesters (tri-OPEs) and organophosphate diesters (di-OPEs) in the runoff of Urumqi No. 1 Glacier and Koxkar Glacier in the Tianshan Mountains, and estimated the output of them from glacial rivers. The total concentration of tri-OPEs (Σ₁₃tri-OPEs) was 8565 pg/L in glacier surface meltwater and 6568 pg/L in proglacial rivers. Di-OPEs exhibited lower concentrations, with 99 pg/L and 117 pg/L (Σ₁₀di-OPEs) in glacier surface meltwater and proglacial rivers, respectively. Tri-OPEs exhibited clear diurnal variations, which are presumed to be related to environmental temperature, while di-OPEs did not show an obvious trend. Although risk quotients (RQs) indicated that the concentrations of OPEs pose minimal risk to the glacier aquatic environment, the Toxicological Priority Index (ToxPi) score results showed that tris(2-chloroethyl) phosphate (TCEP) has the highest priority and therefore requires more attention. The total output flux of OPEs (Σ₁₃tri-OPEs and Σ₁₀di-OPEs) in glacial rivers throughout the entire Tianshan region was estimated to be ∼847 kg/year. Given the continuity of glacial melting and the accumulation of emerging pollutants in glaciers, the process of melting poses an increasing risk to freshwater resources, warranting heightened attention.

有机磷酸酯（OPEs）是一类日益受到关注的化学品。然而，对中纬度冰川环境下OPEs的环境行为、转化和生态风险了解甚少。研究了天山乌鲁木齐一号冰川和科什卡冰川径流中有机磷三酯（triopes）和有机磷二酯（diopes）的浓度和组成特征，并估算了冰川河流中有机磷三酯（triopes）和有机磷二酯（diopes）的产量。三opes总浓度（Σ13tri-OPEs）在冰川表层融水中为8565 pg/L，在前冰川河流中为6568 pg/L。在冰川表面融水和原冰川河流中，二氯opes的浓度较低，分别为99 pg/L和117 pg/L （Σ10di-OPEs）。三opes有明显的日变化，推测与环境温度有关，而二opes无明显的变化趋势。尽管风险商（RQs）表明，OPEs浓度对冰川水生环境的风险最小，但毒理学优先指数（ToxPi）评分结果显示，三（2-氯乙基）磷酸（TCEP）具有最高的优先级，因此需要更多关注。整个天山地区冰川河流OPEs （Σ13tri-OPEs和Σ10di-OPEs）的总输出通量估计为~ 847 kg/年。鉴于冰川融化的连续性和冰川中新出现的污染物的积累，融化的过程对淡水资源构成越来越大的危险，值得进一步注意。

Climate change requires an immediate transition from fossil fuels to clean energy sources. Although hydrogen is considered a future energy source, over 90% of hydrogen is currently produced from fossil fuels, and large-scale renewable-fed hydrogen processes are limited by current technologies and economic processes. Therefore, hydrogen production from fossil fuels is a significant topic, particularly if fossil fuel-fed hydrogen production and utilization can be absolutely carbon-free. For the first time, this review critically discusses and analyses the current advances and fundamentals of fossil fuel dehydrogenation from the perspective of techno-economic-environmental assessments while considering all potential fossil resources and hydrogen technology. This review concludes that the preference of fossil fuels for any hydrogen production technology is as follows: fossil gas > heavy fossil liquid > light fossil liquid > fossil minerals. Thermo-catalytic hydrocarbon decomposition can outperform most other hydrocarbon reforming and pyrolysis processes owing to its energy efficiency, economic effectiveness, and environmental friendliness. Further, we explore potentially new “green hydrogen” technology and confirm that fossil fuels could be completely decarbonized throughout the full-chain stages from exploration to production and consumption. Overall, this work reveals that fossil fuels can be utilized completely carbon-free and provides technical support for future fossil fuel dehydrogenation and energy decarbonization in academic research, industrial practice, and governmental strategies.

气候变化要求我们立即从化石燃料转向清洁能源。虽然氢被认为是一种未来的能源，但目前超过90%的氢是由化石燃料产生的，大规模的可再生氢工艺受到当前技术和经济过程的限制。因此，化石燃料制氢是一个重要的话题，特别是如果化石燃料制氢和利用可以完全无碳。本文首次从技术-经济-环境评价的角度对化石燃料脱氢的现状和基础进行了批判性的讨论和分析，同时考虑了所有潜在的化石资源和氢技术。本文认为，化石燃料对任何制氢技术的偏好为：化石气体；重质化石液体；轻质化石液体；矿物矿物。由于其能源效率、经济效益和环境友好性，热催化烃类分解可以优于大多数其他烃类重整和热解过程。此外，我们探索了潜在的新型“绿色氢”技术，并确认化石燃料可以在从勘探到生产和消费的全链阶段完全脱碳。总体而言，本研究揭示了化石燃料完全可以无碳利用，并为未来化石燃料脱氢和能源脱碳在学术研究、工业实践和政府战略上提供了技术支持。

The air intake-compression systems of modern aircraft usually use the aero-engine intake and fan/compressor as the main components. Inlet-engine compatibility has always been the key to the stable and safe operation of the propulsion system, including the influence of inlet distortion on the compressor performance and stall margin. Since 1950, theoretical models and experiments on the flow stability and inlet distortion of axial compressors have been released. After the 1990s, numerical methods became important tools. In the 21st century, the new trends of aircraft propulsion system/inlet integration, blended wing body, and stealth capability led to a new direction for the inlet-engine flow matching problem. This review aims to combine the development of both the inlet and the axial compressor components, and provides an overview of the research history, latest progress, and prospects of compressor inlet distortion in inlet-engine compatibility problems. Analytical or numerical models, experiments, and simulations related to inlet distortion problems are summarized.

现代飞机的进气压缩系统通常采用航空发动机进气和风扇/压气机作为主要部件。进气道与发动机的兼容性一直是推进系统稳定安全运行的关键，包括进气道畸变对压气机性能和失速裕度的影响。自1950年以来，关于轴流压气机的流动稳定性和进口畸变的理论模型和实验已经发布。90年代以后，数值方法成为重要的工具。进入21世纪，飞机推进系统/进气道一体化、翼体混流、隐身能力等新趋势为进气道-发动机流匹配问题开辟了新的发展方向。本文结合进气道和轴向压气机部件的发展，综述了压气机进气道畸变在进气道-发动机兼容性问题中的研究历史、最新进展和展望。总结了与进气道畸变问题有关的分析或数值模型、实验和模拟。

Tissue-inspired stretchable ionic conductors hold immense promise as core sensing and signal-transmitting elements for human-machine interfaces and soft robotics. Their inherent stretchability and softness allow seamless integration with human skin and other substrates, enabling real-time electrophysiological signal acquisition or sensitive monitoring of deformations and environmental stimuli. However, this innate softness often renders them susceptible to a range of unpredictable mechanical damages, such as fractures, cuts, tears, fatigue, and impacts. Environmental factors like heat, freezing, swelling, and vibrations can also lead to their gradual mechanical deterioration. These diverse damages may induce permanent structural failures, significantly compromising the materials’ stability and long-term reliability in practical applications. This review categorizes and summarizes the recent strategies for designing damage-tolerant stretchable ionic conductors, emphasizing the tunability and evolution of their condensed structures toward high damage resistance. We highlight bio-inspired heterogeneous network designs with viscoelastic polymers, which elegantly address the inherent trade-off between softness and damage tolerance. These advancements in mechanical robustness pave the way for developing a new generation of durable soft devices.

受组织启发的可拉伸离子导体作为人机界面和软机器人的核心传感和信号传输元件具有巨大的前景。其固有的可拉伸性和柔软性允许与人体皮肤和其他基底无缝集成，实现实时电生理信号采集或变形和环境刺激的敏感监测。然而，这种天生的柔软往往使它们容易受到一系列不可预测的机械损伤，如骨折、割伤、撕裂、疲劳和冲击。热、冻结、膨胀和振动等环境因素也会导致它们的机械性能逐渐恶化。这些不同的损伤可能导致永久性结构破坏，严重影响材料在实际应用中的稳定性和长期可靠性。本文对近年来设计耐损伤可拉伸离子导体的策略进行了分类和总结，强调了其凝聚态结构的可调性和向高抗损伤方向发展。我们强调用粘弹性聚合物设计的仿生异质网络，它优雅地解决了柔软性和损伤容忍度之间的内在权衡。这些在机械稳健性方面的进步为开发新一代耐用软设备铺平了道路。

The 2017 Milin earthquake occurred near Namche Barwa on the southeastern Tibetan Plateau. This research employed Sentinel-1 imagery to capture the corresponding coseismic deformation field and adopted a joint inversion approach using geodetic measurements and teleseismic waveform data to assess earthquake mechanics. The coseismic deformation indicated distinct differential movements, indicating a thrust movement of this fault with uplift in northeast side. The calculated seismic moment magnitude was Mw 6.5, with the fault striking of 305° and a dip angle of 72° The earthquake hypocenter was located at a depth of approximately 10 km, and the maximum fault slip was approximately 1.08 m. The event was attributed to the northwestern segment of the Xixingla fault. Numerical simulations indicated a peak ground velocity of approximately 0.3 m/s. The northwestern segment of the Xixingla fault was identified as the seismogenic fault of the event. Furthermore, the Coulomb stress analysis indicates that the earthquake induced stress loading on the Dongju–Milin and Jiali faults. The surface strain analysis reveals a region of high strain adjacent to the fault. The 2017 Milin earthquake occurred because the Xixingla fault underwent predominantly thrust-type sliding due to the continuous tectonic stress induced within the Tibetan Plateau. Notably, the middle segment of the Xixingla fault currently experiences relatively low seismic activity and is in a state of stress and strain accumulation. Thus, strong earthquakes may occur within the middle segment of the Xixingla fault.

本研究利用Sentinel-1影像获取相应的同震形变场，采用大地测量与远震波形数据联合反演的方法进行地震力学评估。同震形变表现出明显的差异运动，表明该断裂为逆冲运动，东北侧隆升。地震矩震级为Mw 6.5，断层走向为305°，断层倾角为72°，震源深度约10 km，最大断层滑动量约1.08 m。该事件发生在西杏拉断裂西北段。数值模拟表明，峰值地面速度约为0.3 m/s。确定西杏拉断裂西北段为该事件的发震断裂。库仑应力分析表明，东聚-米林断裂和嘉里断裂存在地震诱发应力作用。地表应变分析显示断层附近有一个高应变区。值得注意的是，西杏拉断层中段目前地震活动相对较少，处于应力应变积累状态。因此，在西杏拉断层中段可能发生强震。

The coronavirus disease 2019 (COVID-19) continues to have a huge impact on health care and economic systems around the world. The first question to ponder is to understand the flow of COVID-19 in the spatial and temporal dimensions. We collected 7 Omicron clusters outbreaks in China since the outbreak of COVID-19 as of August 2022, selected outbreak cases from different provinces and cities, and collected variable indicators that affect spillover outcomes, such as distance, migration index, PHSM index, daily reported cases number and so on. First, variables influencing spillover outcome events were assessed and analyzed retrospectively by constructing an infectious disease dynamics model and a classifier model, and secondly, the association between explanatory variables and spillover outcome events was constructed by fitting a logistics function. This study incorporates 7 influencing factors and classifies the spillover risk level into 3 levels. If different outbreak sites could be classified into different levels of spillover, it may reduce the pressure of epidemic prevention in some districts due to the lack of a uniform standard, which might be more conducive to achieving the goal of "dynamic zero".

2019年冠状病毒病（COVID-19）继续对世界各地的卫生保健和经济系统产生巨大影响。首先要思考的问题是，从空间和时间维度上理解新冠病毒的流动。我们收集了自2019冠状病毒病（COVID-19）暴发以来截至2022年8月在中国发生的7起Omicron聚集性疫情，选取了不同省市的疫情病例，收集了影响外溢结果的变量指标，如距离、迁移指数、PHSM指数、日报告病例数等。首先，通过构建传染病动力学模型和分类器模型对影响外溢结果事件的变量进行回顾性评估和分析；其次，通过拟合logistic函数构建解释变量与外溢结果事件的关联关系。本研究纳入7个影响因素，将溢出风险等级划分为3个等级。如果可以将不同的疫情发生地划分为不同的外溢程度，可能会减轻一些城市因缺乏统一标准而面临的防疫压力，更有利于实现“动态零”目标。

Spin orbit torque (SOT) of spin current has provided an efficient manipulation of ferromagnet order, antiferromagnet order, and exchange bias field for various spintronic applications. Here, in contrast to the external magnetic field which is very hard to apply locally, we propose to utilize the local control characteristic of SOT on the macro-nano-meter scale to set four different directions of exchange bias field at the IrMn/CoFe interface on one chip simultaneously. Moreover, with this fully electrical control technology to replace the existing various complex processes based on magnetic field annealing, we fabricate monolithic dual-axis full Wheatstone-bridge magnetoresistance sensors to detect two-dimensional magnetic field vector, which exhibit very high detection sensitivity of 9.45 nT

自旋电流的自旋轨道转矩（SOT）为各种自旋电子应用提供了对铁磁体有序、反铁磁体有序和交换偏置场的有效控制。本文针对外部磁场难以局部施加的问题，提出利用SOT在宏观纳米尺度上的局部控制特性，在同一芯片上的IrMn/CoFe界面同时设置4个不同方向的交换偏置场。此外，利用这种全电气控制技术取代现有的基于磁场退火的各种复杂工艺，我们制作了单片双轴全惠斯通桥磁阻传感器来检测二维磁场矢量，该传感器在10 Hz时分别具有9.45 nT·Hz - 1/2和12.3 nT·Hz - 1/2的检测灵敏度，用于x轴和y轴检测。本研究提供了一种利用SOT的局部控制特性同时实现自旋电子器件功能配置的范例。

Functional traits are increasingly used to forecast the response of plant performance to abiotic and biotic conditions. However, it remains unclear how functional traits will mediate the complex responses of plants to interactive drivers in a rapidly changing world. Here, we collected 17-year monitoring data on seedlings of 28 locally coexisting species and 8 functional traits in a temperate forest, and built multi-level regression models to evaluate (1) whether seedling survival varied among species along the acquisitive-conservative strategy gradient, and which functional trait affected seedling survival; and (2) how survival of species with different functional strategies responded to negative density dependence (NDD) and climate variation. We found that species with an acquisitive strategy had higher seedling survival. Specifically, seedling survival was positively correlated with specific root length (SRL), specific leaf area (SLA), and leaf area (LA), but inversely correlated with leaf dry mass content (LDMC). Functional strategies along the acquisitive-conservative gradient showed no significant effects on survival response to conspecific and phylogenetic negative density dependence. Negative effects of heterospecific negative density dependence on seedling survival were weaker for species with higher LDMC, but stronger for seedlings with larger SRL. In addition, species with more conservative strategies had higher resistance to drought stress and freezing damage. For example, species with lower SRL and SLA, and higher LDMC had higher survival under severer seasonal drought. Also, heavier seeds and thicker roots enhanced freezing resistance, whereas higher SRL and LA intensified the negative effects of cold weather. Our study provides strong evidence that functional traits could widely mediate the effects of local biotic interactions and climatic variation on plant performance dynamics, and help to infer community assemblages and species coexistence in the context of a changing world.

功能性状越来越多地用于预测植物对非生物和生物条件的反应。然而，在一个快速变化的世界中，功能性状如何调节植物对交互驱动因素的复杂反应仍不清楚。在此，我们收集了温带森林中28种本地共存物种和8种功能性状的幼苗17年监测数据，并建立了多级回归模型来评估(1)幼苗存活率是否在物种间沿获取-保守策略梯度变化，以及哪些功能性状影响幼苗存活；(2)不同功能策略的物种生存对负密度依赖（NDD）和气候变化的响应。我们发现，具有获取策略的物种幼苗存活率更高。其中，幼苗成活率与比根长（SRL）、比叶面积（SLA）、叶面积（LA）呈正相关，与叶片干质量含量（LDMC）呈负相关。沿着获取-保守梯度的功能策略对同种和系统发育负密度依赖的生存反应没有显著影响。异种负密度依赖对幼苗成活率的负面影响在LDMC高的物种中较弱，在SRL大的物种中较强。此外，保守策略的物种对干旱胁迫和冻害的抗性更高。例如，在严重的季节性干旱条件下，SRL和SLA较低、LDMC较高的物种存活率较高。种子较重、根系较粗增强了抗冻性，而SRL和LA较高则加剧了寒冷天气的负面影响。我们的研究提供了强有力的证据，表明功能性状可以广泛地介导局部生物相互作用和气候变化对植物性能动态的影响，并有助于推断在变化的世界背景下的群落组合和物种共存。

It is of great significance to develop a high-precision and high spatiotemporal resolution of stereoscopic detection technology to finely delineate the horizontal and vertical distributions of CO₂. This study elaborates on the superiorities of single photon spectroscopy, key steps to develop a high-performance single photon LIDAR, and their potential applications. Single-photon CO₂ LIDAR integrates quantum sensing techniques with classical spectral measurement techniques, and can overcome the detection limitations of traditional CO₂ LIDAR in terms of detection distance, sensitivity, and spatiotemporal resolution. We anticipate that the single-photon spectroscopic technology can be widely applied in the detection of regional distribution and emission fluxes of CO₂, transboundary transport fluxes of CO₂, and in supporting the establishment of a new carbon monitoring framework.

开发高精度、高时空分辨率的立体探测技术，对精细刻画CO2的水平和垂直分布具有重要意义。本文阐述了单光子光谱学的优势，高性能单光子激光雷达的关键步骤及其应用前景。单光子CO2激光雷达将量子传感技术与经典光谱测量技术相结合，克服了传统CO2激光雷达在探测距离、灵敏度、时空分辨率等方面的局限性。我们期望单光子光谱技术可以广泛应用于CO2的区域分布和排放通量、CO2的跨界输送通量的检测，并支持建立新的碳监测框架。
