AbstractExpansion microscopy (ExM) facilitates nanoscale imaging under conventional microscopes, but it frequently encounters challenges such as fluorescence losses, low signal‐to‐noise ratio (SNR), and limited detection throughput. To address these issues, a method of orthogonal DNA self‐assembly‐based ExM (o‐DAExM) platform is developed, which employs hybridization chain reaction instead of conventional fluorescence labeling units, showcasing signal amplification efficacy, enhancement of SNR, and expandable multiplexing capability at any stage of the ExM process. In this work, o‐DAExM has been applied to compare with immunofluorescence‐based ExM for cellular cytoskeleton imaging, and the resolved nanoscale spatial distributions of cytoskeleton show outstanding performance and reliability of o‐DAExM. Furthermore, the study demonstrates the utility of o‐DAExM in accurately revealing exosome heterogeneous information and multiplexed analysis of protein targets in single cells, which provides infinite possibilities in super‐resolution imaging of cells and other samples. Therefore, o‐DAExM offers a straightforward expansion and signal labeling method, highlighting future prospects to study nanoscale structures and functional networks in biological systems.
Introduction: The American Climate Emergency Narrative
Authors: Höglund Johan 
Published: July 2024

AbstractThe introductory chapter problematises the prevalent notion that climate fiction written in North America is about a ‘climate crisis’ and that consuming such fiction can help readers move towards more sustainable futures. The introduction thus observes that the present biospheric crisis has been caused not by humans as a species, but by capitalism as a system and that this crucial fact is elided by many climate narratives. The introduction then argues that much of what has been called climate fiction in fact narrates the ongoing socio-ecological crisis as an emergency for capitalism rather than for the planet. In view of this, a better name for these texts is the American Climate Emergency Narrative. With the help of the world-literature perspective, the introduction explains how this is a type of text that emerges out of the core of the world-system and how it participates in the securitization of this world-system and of the US as its hegemon at a time of planetary socio-ecological crisis.
Settler Capitalist Frontiers
Authors: Höglund Johan 
Published: July 2024

AbstractThis chapter shows how writing from the early colonial period registers the extractive relationship between land and people on which the emerging capitalist world-ecology relied. The chapter moves through two distinct historical and narrative stages where the first is the settler colonial text that, from the very beginning, narrated ecology as an emergency-inducing space that needed to be violently combatted, and the second the white pro-slavery and abolitionist text that registered slavery and the plantation as central to the growing US economy, but also as drivers of human and ecological exhaustion.

Published: July 2024

AbstractHighway in mountainous area is easily threatened by landslide and other disasters, so it is necessary to comprehensively evaluate the prevention and control effect of the treatment when the subgrade is restored and rebuilt after landslide. In order to deeply study the landslide treatment effect of subgrade reconstruction, taking the landslide damage reconstruction of G326 highway in Guizhou Province as the object, the deformation and failure process of landslide induced by heavy rainfall is simulated, and the prevention effect of different treatment plans such as “cutting + anti-slide pile + anchor cable” is evaluated. The results show that with the increase of rainfall, the landslide deformation gradually expands from the vicinity of the front national G326 highway to the back edge; Under the combined treatment of “cutting + anti-slide pile + anchor cable”, the maximum displacement of the main sliding area of landslide is 3.1 mm, and the maximum displacement of the trailing edge is 1.7 mm, which makes the overall deformation in a controllable range. As a result, it has certain reference value for the reconstruction of highway subgrade engineering damaged by landslide.

Authors: Fu Yu , Cheng Jiuhuan , Su Juan 
Published: July 2024

AbstractThe suspended ceiling (SC) of LNG storage tank on land is mainly composed of hanger rods, reinforcing rings, and aluminum panels. The hanger rods are prone to damage during earthquakes, which will affect the safe operation of the whole storage tank. In order to facilitate the study of the response of the SC under horizontal seismic shaking, the finite element models of the hanger rods with four different sections, including rectangular, circular, thin-walled circular tube, and groove shape, were established using the ABAQUS software. By inputting EL-Centro horizontal seismic waves, the dynamic time-history analysis is carried out for four hanger rod models with different sections. The response characteristics of acceleration, displacement and internal force with time are obtained, and the comparative analysis results of the maximum peak acceleration (MPA), maximum peak displacement (MPD), and maximum peak internal force (MPIF) at each measuring point are obtained. The results show that the shape of the section has obvious influence on the seismic response of the hanger rods, and the amplitudes of the acceleration-time and displacement-time curves of the hanger rods with different sections are different, and the MPA, MPD and MPIF of the hanger rods are closely related to the shape of the section.

Published: July 2024

AbstractTo overcome the limitations of traditional Markov bridge degradation prediction models, which fail to consider the interactions between different component degradation mechanisms and struggle to accurately capture the true degradation conditions of bridge components, introducing an improved version of the traditional Markov model by incorporating the Weibull distribution. This enhancement results in a semi-Markov model that offers a probability distribution for predicting the technical condition of bridge components. Taking advantage of periodic inspection data from a highway section in Shandong Province, China. With this data, the states of bridge components are defined in the semi-Markov degradation model. The improved semi-Markov model integrates a two-parameter Weibull distribution and involves determining the parameters of the Weibull distribution, transition probability matrix, and state distribution vector. The semi-Markov degradation model, in contrast to commonly used Markov degradation models, accounts for both the state and duration of each state, resulting in significantly more accurate predictions of the degradation process of bridge components, achieving a prediction accuracy of 96%. The developed semi-Markov bridge degradation model facilitates the timely detection of changes in the technical condition of bridge components by updating the transition probability matrix according to variations in the duration of each state, thereby improving the efficiency of subsequent bridge maintenance decision-making.

Published: July 2024

AbstractThis paper evaluates the shear strength of the steel stud connectors in the steel-UHPC lightweight composite bridge deck composed of the orthotropic steel deck with closed U-ribs. The interlaminar shear stress between the UHPC pavement and the steel plate of orthotropic steel deck in the new steel-UHPC lightweight composite bridge deck is computed using the finite element method, in which the influence of wheel loading conditions and overloaded vehicles are studied. Results show that the largest interlaminar transverse shear stress between UHPC pavement and steel plate is induced by the action of triple-axle loading. The interlaminar shear stress between the UHPC pavement and the steel plate will increase significantly under the action of the overloaded vehicles.

AbstractThe soil nutrients, main agronomic indexes, and key yield factors during the maize growth period were studied by using a nutrient expert system to recommend optimal fertilization. The results showed that the fertilizer application had a significant impact on the growth and yield formation of maize, especially the N fertilizer application. N deficiency in maize seriously affected the yield and its component factors, while P and K deficiency had no significant effect on decreasing maize yield. The optimized fertilization treatment (NE) significantly reduced the bald tip length and increased the ear length and the yield of maize by 10.2% compared with the conventional fertilization treatment (FP). NE significantly increased the utilization rate of N, P, and K in maize, which was 20.1%, 12.4%, and 45.4% higher than that of FP. The trend of fertilizer N deficiency was opposite to NE, but P and K deficiency were not obvious. Compared with FP, soil organic matter of NE did not change significantly, and the pH value was increased. Nitrate nitrogen and ammonium nitrogen were decreased by 51.9% and 3.9%, respectively. A significant correlation between maize yield and alkali hydrolyzed nitrogen, organic matter. In conclusion, the optimized fertilization treatment had obvious effects on the growth indicators and yield components of maize, improving the fertilizer utilization rate, and providing technical support for rational fertilization of maize.

AbstractThis study relies on the Huangbuling 500 kV transmission project to investigate the dynamic response law of gas insulated line (GIL) pipe gallery under vehicle traveling loads. A numerical model of GIL pipe gallery considering soil-structure interaction is developed using finite element software ABAQUS, and the effect of soil pressure on GIL is studied through static analysis. This study proposes a continuous step loading method for simulating vehicle traveling loads, and parametric analyses of different traveling directions and speeds are carried out to reveal the GIL’s dynamic response law in depth. The results show that the maximum stresses in the concrete and steel reinforcement cage of the GIL under soil pressure are located at the root of the right-side wall (both are less than the strength design value), and the maximum value of displacement is 6.556 cm occurs in the middle of the top plate. The maximum vertical acceleration, velocity and displacement responses under vehicle load occur at the top midpoint of the pipe gallery, while the maximum stress response occurs at the lower left corner. When heavy vehicle passes over the pipe gallery at different speeds, the peak acceleration, velocity and stress of the pipe gallery tends to increase with the increase of vehicle speed, while the peak displacement does not change significantly.

Authors: Liu Jiangyu , Sun Xiao , Liu Yan , Wang He 
Published: July 2024

AbstractThe study of the stability of rock masses in hydraulic tunnels is a highly complex problem with significant uncertainty, involving a large amount of randomness and fuzziness. Traditional deterministic analysis methods are insufficient in capturing the aforementioned characteristics. Therefore, based on fuzzy random theory, this paper establishes a fuzzy random reliability calculation model for the stability of rock masses in hydraulic tunnels. The model constructs a functional relationship that represents the safety margin of the stability, taking into account the fuzziness and randomness of the failure events in hydraulic tunnels. The proposed model is applied to an engineering case study, and the computed results align well with the actual conditions. This model provides a more accurate reflection of the real state of the rock masses in hydraulic tunnels and offers a scientifically rational alternative for calculating the stability of rock masses in hydraulic tunnels.

Authors: Tan Donglian , Zhao Yue 
Published: July 2024

AbstractSeismic fragility analysis is of paramount significance in studying the seismic characteristics of bridges, especially for special structures like special-shaped bridges. Special-shaped bridges exhibit more complex geometric and mechanical properties. Therefore, it is even more essential to conduct seismic fragility analysis for special-shaped bridges. Analyzing the response of special structures to lateral seismic loads benefits the evaluation of their seismic performance and facilitates enhancements in seismic design. A finite element model was established using Midas/Civil to investigate the seismic fragility of a space special-shaped steel box arch bridge under lateral seismic loads. To assess the seismic fragility of space special-shaped steel box arch bridges, displacement data from bridge abutments, arch support platforms, and bearings were selected as damage indicators. The seismic fragility curves for bridge components were constructed using the incremental dynamic analysis (IDA) method. In the end, the weighting method was adopted to calculate the seismic fragility curve for the entire bridge system. The bearings and bridge abutments are more susceptible to seismic damage under lateral seismic loads, making them the vulnerable components of the bridge. Among the four bearings, the ones located near the arch ribs have poorer seismic performance and constitute vulnerable areas in the bearing layout. Through the case study of the seismic fragility analysis of space special-shaped steel box arch bridge, common issues in the fragility analysis of special bridges were explored. This further provides rational recommendations for enhancing and improving the seismic design of special-shaped bridge structures.

AbstractSecondary grouting can effectively control the ground settlement caused by shield construction and is widely used in urban shield tunnel construction. Therefore, it is necessary to study the grouting material and grouting effect of secondary grouting. Based on the background of below-passed Metro Line, this paper determines the optimal ratio of grouting materials by studying the effects of different cement content and superplasticizer addition on the fluidity, consistency, initial setting time and compressive strength of cement inert slurry, this paper also studies the influence of grouting on the settlement of soil above the tunnel by monitoring the settlement value of soil above the tunnel during grouting. This study contributes to the understanding of grouting techniques in urban shield tunnel construction. The results show that Grouting has a significant effect on controlling the settlement of shield machine in the later stage of crossing, and the ground settlement can be basically stable within 4 days.

AbstractThe subway system has benefited the transportation in a lot of modern cities with advantages such as convenience, rapidity, large volume, etc. However, with the construction of more and more subway systems, the underground space is increasingly crowded. According to engineering practice, existing tunnel is inevitably distorted by adjacent tunneling construction, reducing stability and safety, especially when the distance between two tunnels is small. To explore the convergence deformation of existing tunnels, field monitoring and analysis are conducted on the convergence deformation of the existing tunnel induced by the adjacent tunnel construction. This research finds that: (i) the convergence of each monitoring section gradually develops and stabilizes, and then the convergence of tunnel segments exhibits “horizontal duck egg” pattern and non-uniform convergence pattern; and (ii) after the tunnel shield machine passes, due to the lateral compression deformation of surrounding soil, horizontal convergence of the existing tunnel has an increase in horizontal convergence and a decrease in vertical convergence.
