    Abstract Despite the growing attention being paid to the use of Automated Writing Evaluation (AWE) in China, it is still uncertain what factors lie behind EFL (English-as-a-foreign-language) learners’ continuance intention to use it. To this end, by adding two external factors (i.e., computer self-efficacy and perceived ease of use) to the expectation confirmation model (ECM), we surveyed 345 Chinese EFL learners and tested a number of proposed hypotheses using their response data. Data were analyzed using descriptive statistics and structural equation modeling (SEM). Results demonstrated that four factors directly influenced EFL learners’ continuance intention to use AWE, of which perceived ease of use was the most significant factor. Furthermore, confirmation was the most important factor impacting on EFL learners’ satisfaction and perceived ease of use of AWE. Perceived ease of use of AWE played an important role in influencing EFL learners’ perceived usefulness of AWE. Implications regarding the findings were also discussed.

    Abstract ABSTRACT Introduction: Due to various uncertain and unexpected factors in life such as diseases, natural disasters, traffic accidents, and congenital disabilities, the number and proportion of lower limb amputations are still rising for many reasons, so the research on lower limb prostheses is particularly important. Objective: This work aimed to study the relationship between altitude exercise and cardiopulmonary function. Methods: A model of abnormal changes in cardiopulmonary function was established, and then 40 plateau exercisers were selected, all of whom arrived in Tibet in March 2017. The relationship between pulmonary circulation volume and internal pressure in the chest was observed and compared. The relationship between cardiopulmonary sensory reflex and exercise (high altitude) breathing and heart rate was analyzed. A comparison of the cardiopulmonary function of subjects of different genders was implemented. Moreover, the influence of different altitudes on the subjects’ cardiopulmonary function and the subjects’ cardiopulmonary function changes before departure and during the first, second, and third week after departure were observed and compared. Results: I. As the pressure in the thoracic cavity increased, the subjects’ pulmonary circulation blood volume gradually decreased, and the decrease was most obvious in the stage of thoracic pressure −50 to 0. II. As the cardiorespiratory reflex coefficient increased, the subjects’ breathing and heart rate compensatory acceleration appeared. III. Tracking and monitoring of the subjects’ cardiopulmonary indicators revealed that with the increase in altitude, the subjects’ average arterial pressure, respiratory frequency, and heart rate all showed an upward trend, while the blood oxygen saturation value showed a downward trend. IV. No matter how high the altitude was, the average arterial pressure, respiratory rate, and heart rate monitored of the subjects under exercise were significantly superior to the indicator values under resting state. In contrast, the blood oxygen saturation value showed the opposite trend. V. The subjects’ average arterial pressure, respiration, and heart rate in the first week were higher than other periods, but the blood oxygen saturation was relatively lower. In the second and third weeks, the changes in cardiopulmonary function were relatively smooth (all P<0.05). VI. The changes in the index of the cardiopulmonary function of subjects of different genders were small (p>0.05). Conclusion: Through modeling, the results of the plateau environment on the cardiopulmonary function of the body were made clearer, and these research data provided theoretical references for the training of the sports field in the plateau area. Level of evidence II; Therapeutic studies - investigation of treatment results.

    Abstract At present, the zero-carbon goal has become the common choice of all the world. Driven by the zero-carbon goal, energy system in China will develop to be cleaner and cleaner. In this situation, Energy Internet has become the future development trend of the energy system. Based on the detailed analysis on the development history, the basic connotation and the key features of Energy Internet, an Energy Internet evaluation index system is introduced. This proposed indicator system evaluates Energy Internet from five dimensions, and all the indexes include the qualitative and the quantitative indicators, the process indicators and the result indicators, the technical indicators and the economic indicators. On this basis, an evaluation method is proposed based on the Analytic Hierarchy Process and the Delphi method. The proposed evaluation index system and the evaluation method can provide a good objective evaluation of the development of Energy Internet.

    Abstract With the growth of computer technology and graphic design, to solve the pattern collapse of the generator and improve the diversity of generated results, a study was conducted and designed based on BicycleGAN. A Map2Style module was added to modify the encoder of the model to obtain encoding feature information, thereby improving the accuracy of the encoder and solving the pattern collapse of the generator, thereby increasing the diversity of generated results. The results denoted that the structural similarity indicators of sapphire and white effects were both 0.93. The structural similarity index of the water effect was 0.59, and the peak signal-to-noise ratio index was 28.16. When the batch size was the same, the training time was the same for pattern search generative adversarial network, Bicycle generative adversarial network, and improved method. At this point, the three occupied 3.6, 3.2, and 3.3 GB of video memory, respectively. The area between the receiver operating characteristic curve of the improved model and the coordinate axis was 0.9837, which was higher than that of the Bicycle generative adversarial network, denoting that the improved model had more accurate effectiveness. The performance accuracy of the improved model was 96.31%, and the sensitivity was 80.65%. The improved model has a significant effect, making it more stable and achieving convergence faster during training. It plays a certain role in promoting the application of motion graphics creative design.

    Abstract Post-wildfire debris flows represent a significant hazard for transportation infrastructure. The location and intensity of post-fire debris movements are difficult to predict, and threats can persist for several years until the watershed is restored to pre-fire conditions. This situation might worsen as climate change forecasts predict increasing numbers of wildfire burned areas and extreme precipitation intensity. New insights are needed to improve understanding of how roadways are vulnerable to post-fire flows and how to prioritize protective efforts. Using California as a case study, the vulnerability of transportation infrastructure to post-fire debris flow was assessed considering geologic conditions, vegetation conditions, precipitation, fire risk, and roadway importance under current and future climate scenarios. The results showed significant but uneven statewide increases in the number of vulnerable roadways from the present to future emission scenarios. Under current climate conditions, 0.97% of roadways are highly vulnerable. In the future, the ratio of vulnerable roadways is expected to increase 1.9–2.3 times in the representative concentration pathways (RCPs) 4.5 emission scenarios, and 3.5–4.2 times in the RCP 8.5 emission scenarios. The threat of post-fire debris flow varies across the state, as precipitation changes are uneven. The vulnerability assessment is positioned to (a) identify, reinforce, and fortify highly vulnerable roadways, (b) prioritize watershed fire mitigation, and (c) guide future infrastructure site selection.

    Abstract Karst mountain cities are important population agglomerations in southwestern China, as well as integral components of the significant regional economic belt - the Central Guizhou Economic Belt. Ecological corridors serve as crucial pathways for species migration and play a vital role in integrating regional habitats, particularly in the highly fragmented and ecologically vulnerable karst areas. However, it is not yet clear how human activities and natural factors drive the distribution of ecological corridors in the rapidly expanding urban areas of karst region. In light of this, based on multi-source data from 2005 to 2020, this study identified ecological source areas using ecological sensitivity analysis and a resistance surface model was adjusted using the rocky desertification factor. The Minimum Cumulative Resistance (MCR) model was employed to extract ecological corridors for each of the four time periods. Furthermore, space syntax analysis was conducted to evaluate the selection, integration, and depth of the corridors under different levels of urbanization. Finally, correlation analysis in R language was performed to determine the degree of influence of various driving factors on the distribution of ecological corridors. Our findings indicate that during the urbanization process, the negative impact of human disturbance factors on corridor distribution in highly urbanized areas has decreased. And the overall development of ecological corridors in the research region has shown improvement over the past 20 years. However, extreme climatic conditions have negatively affected the distribution of ecological corridors. Additionally, policy-driven measures will have an impact on the distribution of ecological corridors. By exploring the spatiotemporal differentiation and driving mechanisms of corridors in Karst mountain cities over the past two decades, our research will provide scientific evidence for biodiversity conservation and the construction of ecologically secure environments in karst areas.

    Abstract Reverse logistics is attracting attention due to the increasing concerns over environmental issues and the important economic impacts. The design of a reverse logistics network is a major strategic problem in the field of reverse logistics. As cost pressures in product returns continue to mount, a growing number of manufacturers have begun to outsource reverse logistics operations to third-party logistics (3PL) providers. On the other hand, considering disruption risks caused by natural or man-made factors in the reverse logistics network design is inevitable. This paper studies third-party reverse logistics network designs under uncertain disruptions. The problem is formulated as a risk-averse two-stage stochastic programming model with a mean risk objective. Two types of risk measures, value at risk (VaR) and conditional value at risk (CVaR), were examined, respectively. Finally, the sensitivity analysis of the model was carried out. The validity of the mean risk criteria is proved by comparison with risk-neutral approach. Moreover, the performance of the proposed model was examined by stochastic measures.

    Abstract ABSTRACTDifferences in human mobility reflect temporal variations and spatial differences in urban spaces, including regional functions, physical environments, and geographical sentiments. Accurately quantifying these differences is critical for understanding and managing cities. However, existing measurement methods overlook the spatial distribution of population movement, which limits the ability to compare spatial differences in human mobility. Separate treatment of the spatial distribution, flux, and distance of human movement increases the complexity and uncertainty of understanding geographic phenomena. Therefore, we propose a flow-based location measure, termed the mobility difference index (MDI), that fuses multidimensional movement characteristics to quantify temporal variations and spatial differences in human mobility. The method quantifies the differences in human mobility by calculating the minimum transformation cost between two sets of origin-destination flows based on optimal transport theory. Simulation experiments confirmed the advantage of the MDI in perceiving the multidimensional characteristics of human movement, particularly regarding spatial distribution. We examined mobile signaling and positioning data from Wuhan and found that the proposed MDI could effectively identify the spatial and temporal dependencies of variations in human mobility and heterogeneous effects of spatial semantics and distance on spatial differences in human mobility.

    Abstract Due to their geometry and thermal physiology, hands are most vulnerable to cold weather injuries and loss of dexterity. Gloves are the most common for hand protection during exposure to extreme thermal and hazardous environments. Although glove microclimate properties such as area factor, air gap thickness, and contact area play a significant role in thermal protection, identifying local (at individual hand segments) glove microclimate properties is still a research gap. For the first time, the glove-microclimate properties for 16 hand segments at high spatial resolution were analyzed by employing state-of-the-art hand-held 3D scanner and post-processing techniques for different glove types. Our results clearly indicate that the glove area factor for distal phalanges is significantly higher (by 49.8 %) than that for other hand segments, which increases the heat transfer from distal phalanges. In contrast, average air gap thickness was relatively uniform across all hand segments. The glove type had a pronounced effect on glove microclimate properties, e.g., bulky and heavy cold weather protective gloves had a larger average air gap thickness and glove area factor. Regression models are also developed to estimate the glove microclimate properties from simple measurement (i.e., ease allowance). Overall, this study provides essential information for the design and development of protective gloves that can help improve safety, comfort, and dexterity. Methods and mathematical models developed in this study also contribute to facilitating extremity (e.g., hand) focused thermoregulation modeling, hazard simulation, injury prediction, ergonomic design, optimum performance (dexterity and tactility) along with thermal protection.
