Abstract	BOPS (Buy Online, Pick up in Store) is a popular channel strategy that plays an important role in promoting the sustainable development of omni-channel retailing. Focusing on consumer’s sustainable usage intention of BOPS service, this paper uses a Technology Acceptance Mode (TAM) framework to investigate how the channel integration quality influences the willingness to adopt BOPS service from four dimensions: channel service transparency, channel choice breadth, content consistency, and process consistency. Our findings support previous research in the TAM field, as perceived usefulness and perceived ease of use strongly affect consumer’s favorable attitude towards BOPS service. The pivotal roles of channel service transparency and process consistency in the formation of BOPS using intention is verified, as they both have positive effect on perceived usefulness and perceived ease of use. However, channel choice breadth indirectly affects the sustainable usage intention of BOPS through perceived usefulness but has no significant effect on perceived usefulness. In addition, content consistency positively affects perceived ease of use, but the diversity of channels does not necessarily make consumers find BOPS more useful. On this basis, the implications of BOPS service management are discussed.

Abstract	Establishing wildlife corridors to link detached habitat patches is a widely advocated conservation strategy to reduce the adverse impacts of habitat fragmentation. Given the scarcity of conservation resources, designing an efficient corridor system calls for an optimization approach. The optimal configuration of a wildlife corridor system involving multiple habitat patches poses significant challenges, both methodologically and computationally. This study proposes a two-stage procedure for that purpose. In the first stage, we determine a best-quality corridor between each pair of habitat patches using the method described in Wang et al. (2022). In the second stage, we select a subset of those corridors to assemble a least-cost corridor system using a mixed integer linear programming model presented in this paper. We use an illustrative example to demonstrate the workings of the two-stage method, and then apply it to a real dataset for an area in Cumberland County, Nova Scotia, Canada, involving 1039 irregular land parcels. Results show that an efficient corridor system where each habitat patch is connected to some neighboring habitat patches through a specified minimum number of corridors can be identified conveniently in terms of both data processing and computational effort.

Abstract	Protected areas (PAs) are an important estate for sustainable development. Children in PAs are of particular concern, as they are potential future stakeholders of this estate, yet they may be the ones affected the most by the conservation and development programs in PAs. However, knowledge on children in PAs has been very limited, which threatens the probability of the success of both nature conservation and sustainable development. In this paper, we present the findings from a questionnaire survey targeted at schoolchildren in China’s PAs. Our sample consisted of 41 primary schools across China. We looked at 22 indexes of the sample, inferred the conditions in the whole PAs using an exact binomial test, and compared them with those in other rural or urban areas in China. We found that schoolchildren in PAs are substantially disadvantaged in terms of many indexes, both in school and at home. We discuss possible reasons, link these results to Sustainable Development Goals (SDGs), and discuss some policy implications. With this preliminary study, we hope to stimulate additional research on the conditions of children in PAs and their potential implications for sustainable development.

Abstract	Lake ecosystems play a crucial role in maintaining global biodiversity, flood storage, and water purification. Fish living in lakes and their habitat quality are significant indicators of the overall health of the lake ecosystem. In recent years, the impact of climate change and human activities on lake habitats has become an important research topic. In this paper, using fish as an indicator species, the habitat factors of lake fish were classified into hydrological factors, water quality factors, topographic and substrate factors, and biological factors, based on which the influence mechanism of each factor of the lake habitat system on fish was sorted out. We used the VOSviewer bibliometric analysis tool to visualize the knowledge map and identify current research hotspots and development trends related to simulation and assessment methods for lake fish habitats. Additionally, we reviewed the research progress of four types of lake habitat models. Based on the current research perspectives and shortcomings, a research framework for assessing the risk of lake habitat degradation is proposed, which consists of four parts. This framework could establish a theoretical foundation for the protection and restoration of lake ecosystems.

Abstract	Depression is of increasing concern as its prevalence increases. Our study's objective was to create and evaluate a nomogram to predict the likelihood that hypertension patients may experience depression. 13293 people with hypertension who were under 20 years old were chosen from the National Health and Nutrition Examination Survey (NHANES) database between 2007 and 2018 for this study. The training and validation sets were split up into the dataset at random in a 7:3 ratio. To find independent predictors, univariate and multivariate logistic regression were employed on the training set. Using information from the validation set, nomogram was subsequently created and internally validated. The effectiveness of the nomogram is assessed using calibration curve and receiver operator characteristic (ROC) curve. Combining univariate logistic regression analysis and multifactor logistic regression analysis, the results showed that age, sex, race, marital, education level, sleep time on workdays, poverty to income ratio, smoking, alcohol consumption, sedentary time and heart failure status were risk factors for hypertensive patients suffering from depression and were included in the nomogram model, and ROC analysis showed that the AUC of the training set was 0.757 (0.797-0.586), with a sensitivity of 0.586; the AUC of the test set was 0.724 (0.712-0.626), with a sensitivity of 0.626, which was a good fit. Decision curve analysis further confirms the value of nomogram for clinical application. In the civilian non-institutionalized population of the United States, our study suggests a nomogram that can aid in predicting the likelihood of depression in hypertension patients and aiding in the selection of the most effective treatments.

Abstract	The accumulation of discarded mollusk shells has occupied a large land area and caused severe environmental pollution problems. Discarded mollusk shells are mainly composed of calcium carbonate and therefore can be used for the removal of heavy metals from the contaminated aquatic environment. Theoretically, shells with a smaller powder size have a higher adsorption capacity for heavy metal ions. However, the agglomeration and the outflow of small particles limit the applications of mollusk shells in water treatment practices. To overcome the shortcomings of mollusk shells in heavy metals adsorptions, a polymer composite material comprising poly (vinyl alcohol)/oyster shell powder (PVA-OSP) was prepared with the solution casting method for the adsorption of heavy metal ions from wastewater. The structures and the heavy metal adsorption properties of the oyster shell powder (OSP) and the composite PVA-OSP were studied and compared. Analysis results of XRD and FT-IR showed a successful combination of OSP and PVA by a chemical cross-linking modified with sodium silicate. The composite PVA-OSP has good thermal stability for common adsorption processes. The adsorption results showed that the adsorption capacity of the PVA-OSP composite for both Cu2+ and Cd2+ was much higher than that of the OSP. The adsorptions of Cu2+ and Cd2+ on the OSP followed the pseudo-second-order kinetic model as well as the Temkin and Freundlich isotherm model. Comparatively, the adsorptions of heavy metal cations on the PVA-OSP followed the pseudo-first-order kinetic model as well as the Temkin and Langmuir isotherm model. In conclusion, this study showed that the PVA-OSP composite materials may be useful in the treatment of wastewater polluted by heavy metals.

Abstract	Novel profile control agents are constantly emerging in the field of enhanced oil recovery, contributing to the extension of a stable production period. However, evaluation performed through conventional core flow experiments is usually inadequate to reveal the in-depth mechanism of profile control agents. Besides, due to different operation and production modes, there is an urgent need for a specific experimental method applicable to horizontal wells in bottom water reservoirs. In this context, this paper describes two models tailored to bottom water reservoirs and investigates the flow characteristics and mechanisms of three water-shutoff agent types. At the pore scale, further study was carried out on the water-shutoff synergism between a gel and an emulsifier. The results show that the gel is present at the edge of the pore body, while the emulsion is blocked in the center of the pore body. Hence, gel that enters a water channel (main flow and accumulation area of emulsion) can cooperate with an emulsion to achieve high-strength water shutoff, making the bottom water that re-invades mainly break through at oil-rich areas. Compared with water shutoff with gel alone (randomly distributed in the breakthrough area), the synergism improves the gel’s ability to select flow channels, inhibits emulsifier channeling, and achieves a remarkable EOR effect.

Abstract	Accurate forecasting of solar radiation (Rs) is significant to photovoltaic power generation and agricultural management. The National Centers for Environmental Prediction (NECP) has released its latest Global Ensemble Forecast System version 12 (GEFSv12) prediction product; however, the capability of this numerical weather product for Rs forecasting has not been evaluated. This study intends to establish a coupling algorithm based on a bat algorithm (BA) and Kernel-based nonlinear extension of Arps decline (KNEA) for post-processing 1–3 d ahead Rs forecasting based on the GEFSv12 in Xinjiang of China. The new model also compares two empirical statistical methods, which were quantile mapping (QM) and Equiratio cumulative distribution function matching (EDCDFm), and compares six machine-learning methods, e.g., long-short term memory (LSTM), support vector machine (SVM), XGBoost, KNEA, BA-SVM, BA-XGBoost. The results show that the accuracy of forecasting Rs from all of the models decreases with the extension of the forecast period. Compared with the GEFS raw Rs data over the four stations, the RMSE and MAE of QM and EDCDFm models decreased by 20% and 15%, respectively. In addition, the BA-KNEA model was superior to the GEFSv12 raw Rs data and other post-processing methods, with R 2 = 0.782–0.829, RMSE = 3.240–3.685 MJ m −2 d −1 , MAE = 2.465–2.799 MJ m −2 d −1 , and NRMSE = 0.152–0.173.

Abstract	Reflective tomography Lidar has been proved to be a new Lidar system with long distance and high resolution. The reflective tomography Lidar image is prone to clutter and artifacts; thus, it is important for space target recognition to extract the target from the image. In this study, we proposed image fusion algorithm combined with visual saliency could be applied to the target extraction of reflective tomography Lidar image, which can not only preserve the target information but also eliminate the clutter and artifacts in the image. The efficiency of this algorithm is shown by simulation and the experiment of the reflective tomography Lidar system. Also, we analyzed the main source of reflective tomography Lidar image artifacts and the reason why this algorithm could remove clutter and artifacts.

Abstract	Military installations are valuable in global biodiversity conservation as they secure representative ecosystems from land conversion and protect many threatened or endangered species. Selecting suitable areas for biodiversity conservation within military installations is a challenging problem as this must not impede military training activities. The issue gets more complicated when considering multiple cohabiting species in a metacommunity with species dependency. In this paper, we present an example for the conservation of two cohabiting species, Gopher Tortoise (GT) and Gopher Frog (GF), located within the boundaries of a military installation, Fort Stewart, Georgia, United States. The GF depends on both locations of GT habitat (burrows) and ephemeral vernal ponds (for breeding). We develop a model that identifies the cost-efficient areas for the conservation of these two species while taking into account the dependency of GF on GT burrows. The model selects a specified number of conservation areas for the two species, where each GF conservation area covers an adequate number of vernal ponds for the GFs to accommodate their reproduction, and each GT conservation area provides adequate habitat quality to sustain a viable GT population. The model also requires each GF site to be located close to GT sites so that the GFs could find refuge after they leave the water. We use the total distance of selected sites to the main roads in the military installation as a proxy for the conservation cost. We achieve contiguity of each conservation area by selecting sites that are adjacent to a central site of the conservation area to ensure undisrupted travel for both the GFs and the GTs. Using the model, we generated alternative configurations of conservation areas that could be considered by the land managers of Fort Stewart. Our methods are general and can be applied to other reserve site selection and land management problems with cohabiting interrelated species.
