    Abstract Abstract High temperature stress poses significant adverse effects on crop yield and quality. Yet the molecular mechanisms underlying heat stress tolerance in plants/crops, especially regarding the organellar remodeling and homeostasis, are largely unknown. In a recent study, Zhou et al. reported that autophagy-related 8 (ATG8), a famous regulator involved in autophagy, plays a new role in Golgi restoration upon heat stress. Golgi apparatus is vacuolated following short-term acute heat stress, and ATG8 is translocated to the dilated Golgi membrane and interacts with CLATHRIN LIGHT CHAIN 2 (CLC2) to facilitate Golgi restoration, which is dependent on the ATG conjugation system, but not of the upstream autophagic initiators. These exciting findings broaden the fundamental role of ATG8, and elucidate the organelle-level restoration mechanism of Golgi upon heat stress in plants.

    Abstract A large-scale energy emergency production plan driven by extreme events in energy supply chain networks is the low-probability/high-consequence event that is difficult to prepare. One of the most prominent challenges is efficiently computing the equilibrium point characterized with more frequently involved in common resource conflicts due to different player behaviors in energy supply chain networks. In this paper, a novel large-scale equilibrium model of energy emergency production: embedding social choice rules into Nash Q-learning automatically achieving consensus of urgent recovery behaviors, is proposed to tackle this challenge. The main contributions of this work are that firstly set up a large-scale equilibrium model of energy emergency production to formulate energy emergency production plans by modifying the large-scale energy equilibrium model, and the computational limitations of Generalized Nash Equilibrium are overcame by combination of Nash Q-learning methods and individuals’ preferences reaching a collective decision which guarantees uniqueness of the large-scale Nash equilibrium to achieve both system-level efficiency and maximum fairness. Simulations results show that the generalized Nash bargaining solution can be implemented by the proposed large-scale equilibrium model of energy emergency production, in which outcome of the game is the emergency production stable equilibria alternative with no chance moves in a given consensus level, and compared with the existing techniques considering non-cooperative behaviors, it has a significantly lower minimisation of time for the energy restoration by twenty-nine percent, and reduces minimisation of cost for the energy restoration by seventeen percent and minimisation of carbon dioxide emissions by twenty-three percent with disaster recovery.

    Abstract Summary: In the winter months, the temperature in most of the Earth stays below 0°C; the average temperature in winter at the South Pole is about −60°C. Therefore, it is urgent to develop efficient catalytic systems for selective and efficient H2 evolution upon NH3BH3 hydrolysis at subzero temperatures. For solving the freezing issue of water at below 0°C, herein, we have employed a facile and surfactant-free approach to synthesize M-Pt/C nanocomposites (M = Pd, Rh, Ru, Ni, Cu, or Fe), by the alloying of commercial Pt/C with Pd, Rh, Ru, Cu, Ni, or Fe for selective and efficient H2 evolution upon NH3BH3 hydrolysis in saline solution at below 0°C, even at −15°C. In addition, NH3BH3 hydrolysis over Pd-Pt/C in the saturated NaCl solution is utilized not only for safe hydrogen production but also for its in situ hydrogenation reduction in organic chemistry, which could avoid using dangerous hydrogen cylinders.

    Abstract In this paper, we develop a DSGE model including heterogeneous households, introduce the financial friction of credit constraint mechanism, and study the impact of house price shocks on the consumption of heterogeneous household. Based on this, the CHFS data in 2011, 2013, 2015, 2017, and 2019 were used to test the marginal propensity to consume for housing wealth appreciation under different credit constraints. Results show that: Firstly, the financial accelerator mechanism plays an important role in the transmission of housing price shocks to household consumption. The looser the degree of credit constraints, the more obvious the rise in housing prices will be to the consumption expenditure of borrowing household. Secondly, the impact of housing wealth appreciation on household consumption under different credit constraints is heterogeneous. Among them, housing wealth appreciation has a significant positive impact on household consumption expenditure with multiple houses, credit cards, non-loan restrictions, while the marginal effect on the consumption expenditure of households with only one house, loan limited, and no credit cards decreases. Thirdly, for every 1% increase in the housing wealth appreciation, household consumption will increase significantly by 0.10-0.14%.

    Abstract Summary: Sodium formate (SF) is regarded as a technological additive to improve H2 generation upon HCOOH dehydrogenation. The development of SF as a hydrogen storage material is still a challenge. Herein, we report the design and synthesis of carbon nanosphere-stabilized Pd nanoparticles (Pd/CNS) for the direct H2 generation upon SF hydrolysis in the presence of Fe3+. The tandem reaction, isotopic mass spectrometry, and gas chromatograms result confirmed that SF hydrolysis generates H2 with one H atom provided by SF and other H by H2O. The kinetic study and detailed mechanistic investigations have demonstrated that the concerted process between the cleavage of O-H bond in H2O and -O2C-H bond oxidative addition is the rate-controlling step in SF hydrolysis. This work offers a new chemical hydrogen storage material (HCOONa) for the high-efficiency generation, transport, and storage of H2.

    Abstract Fleet electrification is one of the most promising strategies to mitigate carbon emissions and improve air quality. This study provides a comprehensive analysis of the currently unclear CO2 mitigation and human health benefits from electric vehicle (EV) adoption and energy decarbonization in the Yangtze River Delta (YRD) region by integrating fleet modeling, emission projection, air quality modeling and health risk assessment. Based on future socioeconomic trajectories, we project that the total vehicle stock in the YRD region will peak at 107–117 million around 2045–2050. The transition to EVs combined with largely renewable energy in the YRD region can potentially reduce CO2 emissions by 870 Tg in 2060 and brings along substantial health co-benefits with ∼360 avoided premature deaths per million from reduced PM2.5 and O3 concentrations. This study further explores the NO2-attributable burden from road transportation and reveals that fleet electrification could yield greater NO2-attributable health benefits than those from reduced PM2.5 and O3, especially in traffic-dense urban areas. Those findings indicate that China’s near-term energy development plans (35% renewable energy) have created the conditions for large-scale EV adoption. Our results imply that the benefits of EVs exhibit substantial spatial heterogeneity, underscoring the importance of region-specific EV incentive policies, and hint that policymakers should prioritize densely populated megacities to maximize the potential for public health gains.

    Abstract AbstractThe construction of urban excavation involves several potential risks, and the application of scientific methodologies is necessary for a reliable risk assessment. This paper proposes a novel risk assessment framework for urban excavation that combines the fuzzy analytic hierarchy process (FAHP) with the multi criteria compromise solution ranking (VIKOR) approach. FAHP is utilised to determine the weights of risk factors and identify high risk factors, and VIKOR is employed to evaluate the risk level of urban excavation. The proposed method comprises five key components: information source collection, risk-factor rating, weight calculation, establishment of project classification standards, and project feedback. By comprehensively considering the weights of various evaluation indicators and the superiority or inferiority of different factors, this method provides comprehensive risk assessment results. The effectiveness and feasibility of the proposed method are validated through a real case conducted in Nanning, China. The FAHP-VIKOR risk assessment method offers scientific decision support for urban excavation construction and serves as a valuable reference for risk reduction and ensuring construction safety.

    Abstract To address the issues of low automation, reliance on manual screening by professionals, and long detection cycles in current urban drainage pipeline defect detection, this study proposes an improved object detection algorithm called EFE-SSD (enhanced feature extraction SSD), based on the SSD (Single Shot MultiBox Detector) network. Firstly, the RFB_s module is added to the SSD backbone network to enhance its feature extraction capabilities. Additionally, multiple scale features are fused to improve the detection performance of small target defects to some extent. Then, the improved ECA attention mechanism is used to adjust the channel weights of the output layer, suppressing irrelevant features. Finally, the Focal Loss is employed to replace the cross-entropy loss in the SSD network, effectively addressing the issue of imbalanced positive and negative samples during training. This increases the weight of difficult-to-classify samples during network training, further improving the detection accuracy of the network. Experimental results show that EFE-SSD achieves a detection mAP of 92.2% for four types of pipeline defects: Settled deposits, Displaced joints, Deformations, and Roots. Compared to the SSD algorithm, the model’s mAP was increased by 2.26 percentage points—ensuring the accuracy of pipeline defect detection.
