Prediction of Shear Bond Strength of Asphalt Concrete Pavement Using Machine Learning Models and Grid Search Optimization Technique

Determination of Shear Bond strength(SBS)at interlayer of double-layer asphalt concrete is crucial in flexible pavement structures.The study used three Machine Learning(ML)models,including K-Nearest Neighbors(KNN),Extra Trees(ET),and Light Gradient Boosting Machine(LGBM),to predict SBS based on easily determinable input parameters.Also,the Grid Search technique was employed for hyper-parameter tuning of the ML models,and cross-validation and learning curve analysis were used for training the models.The models were built on a database of 240 experimental results and three input variables:temperature,normal pressure,and tack coat rate.Model validation was performed using three statistical criteria:the coefficient of determination(R2),the Root Mean Square Error(RMSE),and the mean absolute error(MAE).Additionally,SHAP analysis was also used to validate the importance of the input variables in the prediction of the SBS.Results show that these models accurately predict SBS,with LGBM providing outstanding performance.SHAP(Shapley Additive explanation)analysis for LGBM indicates that temperature is the most influential factor on SBS.Consequently,the proposed ML models can quickly and accurately predict SBS between two layers of asphalt concrete,serving practical applications in flexible pavement structure design.

Supply-Side Structural Reforms and China's Potential Economic Growth Rate

This paper examines the effect of supply-side structural reforms on China＇s potential economic growth rate in the coming decade according to the data the authors have gathered. Under the rapid growth scenario with the implementation of supply-side structural reforms, China＇s potential economic growth rate will reach an average of 6.5% and 5.8% respectively in the 13th Five-year Plan （2016-2020） and 14th Five-year Plan （2021-2025） periods. These rates are 0.2 and 0.3 percentage points higher, respectively, than that under the baseline scenario with the inertia of historic trends. In implementing supply-side structural reforms, China must transform governmental functions, break monopolies, create a comprehensive competitive market environment, foster the creation of pro-innovation mechanisms, refocus on quality and efficiency, and raise capital utilization and labor productivity.

China's Infrastructure Development and Supply-Side Structural Reforms

Despite significant improvements in transport, energy and information communication technology （ICT） infrastructures, inadequacies still exist in China＇s infrastructure development in light of emerging demand and industrial transition and upgrade. China lags far behind advanced economies such as the United States, Germany and Japan in terms of the quality of transport infrastructures except railroad,＂ electricity infrastructure is insufficient and service efficiency needs improvement; ICT infrastructure requires all-round upgrade and gaps in Internet bandwidth are striking. This paper suggests that, based on the needs of supply-side structural reform, China must reform its investment and financing systems to enhance the efficiency of infrastructure investment. Efforts must be made to enhance air transport and port infrastructure to support industrial upgrade; to develop the energy Internet to address emerging demands; and to forge a new generation of ICT infrastructure with industrial Internet as the priority to prepare China for the new round of industrial competition.

China＇s Economic Slowdown under Supply-Side Perspective

This paper creates an analytical framework for ongoing China＇s economic slowdown and reveals the major.factors affecting potential growth rate. First, proceeding from the factors that led to a decline in China ＇s potential growth rate, this paper demonstrates that the slowdown since 2012 is not caused by demand-side shock.s＇ but is a natural result of the demographic transition and the change of economic development stage that stemmed from supply-side factors. It is therefore suggested that the demand- side perspective for cyclical analysis must be abandoned and the supply-side perspective for growth analysis ought to be followed Secondly, this paper argues that it is theoretically unjounded and empirically unconvincing for existing literature based on the growth perspective to simply apply the statistical pattern of ＂regression towards the mean＂ to forecast China ＇s growth outlook and thus arrive at pessimistic conclusions. On this basis, this paper identifies a host of initiatives that can significantly increase potential growth rates and proposes policy recommendations for deriving reform dividends foom supply-side structural reform.

On the Supply-side Structural Reform in the Oil and Gas Industry

The supply-side structural reform in the oil and gas industry can be divided into three different levels. At present, there are four major categories of problems—a weak supply insurance capacity, a structural supply and demand imbalance, a certain degree of excess capacity and an imperfect market system. The primary target of supply-side reform in the oil and gas industry is ensuring a clean and efficient supply. The focus is to optimize the allocation of resources, improve resource allocation efficiency, and improve total factor productivity. Under the new situation, we should adjust the strategy and tactics used for supply insurance and carry out three tasks. We must adhere to the principles of "marketization", "globalization" and "integration" reform, strengthen the building of supply insurance capacity, improve the oil and gas market system, optimize the industry structure, and resolve excess capacity.

Study of the Development of Chinese sports Industry in the Context of Supply-side Structura Reform

In recent years,China’s sports industry has witnessed rapid development gradually forming an emerging strength in its Supply-side Structural Reform and thus increasingly being highlighted in the development of the nationa economy.Being integrated,society-based,green and sustainable,the sports industry is gaining popularity among the Chinese people.This paper studies the overall development of Chinese sports industry during the 12th FiveYear Plan period(2011-2015)and unveils the key achievements it made,such as the expansion of scale,the diversification of products and services,the improvement of industry policies,the apparent upgrading and optimization of the industry’s structure and its further integration with the Internet However,there are still some problems in the development of China’s sports industry&Chinese sports industry accounts for a fairly low proportion in the gross domestic product(GDP)and cannot yet compare with those of developed countries.Besides,given that its the sports services make up only a small share and that a supply-demand imbalance still exists in the sports products and services,its industrial structure requires further upgrading and optimization.In addition,failure to fully stimulate an innovation initiative restricts this industry’s further development.Targeting the bottleneck facing Chinese sports industry and corresponding path selection,this paper mainly analyzes its institutional mechanism reform,structural upgrading and layout product quality improvement and talent supply optimization.Based on the analysis,it is concluded that the development of Chinese sports industry is of great importance to China’s economic transformation,upgrading and healthy development and it echoes the call of Supply-side Structural Reform.

Setting the Structural Reform of Supply-Side as the Focus and Shifting the Economic Development Model

To focus on SRSS during the 13th Five-Year Plan period(2016-2020) is a necessary response to the changes of the international economic environment and to China's goal of achieving the new normal in economic development. The main reason why the focus shifts from changing EDM to reforming the supply-side structure lies in the fact that structural reform boosts the transformation of EDM, and only by accomplishing the former will the latter be realized. Today SRSS is faced with challenges like different ideologies, insufficient conditions and backward regulations. It should be led by the Five Major Development Concepts proposed by President Xi Jinping, "Innovation, coordination, greenness, openness and sharing," and the "supply-side" and "demand-side" must be simultaneously propelled.

The 13^(th) Five Year Plan is a critical period for the transformation of economic development patterns and economic restructuring, so clarifying the theoretical values and practical significances of the supply-side structural reforms, making a clear explanation of the scientific connotations and policy implications of these reforms from a scientific standpoint, and discussing concrete measures to promote the reforms against the background of the economic new normal not only has academic values but also has important practical implications. Viewed from the practical standpoint of China' s new normal and through analyzing the basic national conditions, this article proposes a roadmap for implementing the proposed reforms and points out that only by doing well in the hybrid operation of "addition, subtraction, multiplication and division", based on the framework of the "five policy pillars", an innovative path of the supply-side structural reforms with Chinese characteristics can be paved.

Evolutionary Neural Architecture Search and Its Applications in Healthcare

Most of the neural network architectures are based on human experience,which requires a long and tedious trial-and-error process.Neural architecture search(NAS)attempts to detect effective architectures without human intervention.Evolutionary algorithms(EAs)for NAS can find better solutions than human-designed architectures by exploring a large search space for possible architectures.Using multiobjective EAs for NAS,optimal neural architectures that meet various performance criteria can be explored and discovered efficiently.Furthermore,hardware-accelerated NAS methods can improve the efficiency of the NAS.While existing reviews have mainly focused on different strategies to complete NAS,a few studies have explored the use of EAs for NAS.In this paper,we summarize and explore the use of EAs for NAS,as well as large-scale multiobjective optimization strategies and hardware-accelerated NAS methods.NAS performs well in healthcare applications,such as medical image analysis,classification of disease diagnosis,and health monitoring.EAs for NAS can automate the search process and optimize multiple objectives simultaneously in a given healthcare task.Deep neural network has been successfully used in healthcare,but it lacks interpretability.Medical data is highly sensitive,and privacy leaks are frequently reported in the healthcare industry.To solve these problems,in healthcare,we propose an interpretable neuroevolution framework based on federated learning to address search efficiency and privacy protection.Moreover,we also point out future research directions for evolutionary NAS.Overall,for researchers who want to use EAs to optimize NNs in healthcare,we analyze the advantages and disadvantages of doing so to provide detailed guidance,and propose an interpretable privacy-preserving framework for healthcare applications.

Cooperative UAV search strategy based on DMPC-AACO algorithm in restricted communication scenarios

Improvement of integrated battlefield situational awareness in complex environments involving dynamic factors such as restricted communications and electromagnetic interference(EMI)has become a contentious research problem.In certain mission environments,due to the impact of many interference sources on real-time communication or mission requirements such as the need to implement communication regulations,the mission stages are represented as a dynamic combination of several communication-available and communication-unavailable stages.Furthermore,the data interaction between unmanned aerial vehicles(UAVs)can only be performed in specific communication-available stages.Traditional cooperative search algorithms cannot handle such situations well.To solve this problem,this study constructed a distributed model predictive control(DMPC)architecture for a collaborative control of UAVs and used the Voronoi diagram generation method to re-plan the search areas of all UAVs in real time to avoid repetition of search areas and UAV collisions while improving the search efficiency and safety factor.An attention mechanism ant-colony optimization(AACO)algorithm is proposed for UAV search-control decision planning.The search strategy is adaptively updated by introducing an attention mechanism for regular instruction information,a priori information,and emergent information of the mission to satisfy different search expectations to the maximum extent.Simulation results show that the proposed algorithm achieves better search performance than traditional algorithms in restricted communication constraint scenarios.
