Dynamically reversible cooperation and interaction of multiple rotating micromotors.

Micromotors have been shown to have great potential in various fields (e.g., targeted therapeutics, self-organizing systems), and research on the cooperative and interactive behaviours of multiple micromotors could potentially revolutionize many fields in terms of performing multiple or complex tasks to compensate for the limitations of individual micromotors; however, dynamically reversible transitions among diverse behaviours remain much less explored, and such dynamic transformations are advantageous for achieving complex tasks. Here, we present a microsystem consisting of multiple disk-like micromotors capable of performing reversible transformations between cooperative and interactive behaviours at the liquid surface. The micromotors with aligned magnetic particles in our system have great magnet properties, which provides a strong magnetic interaction with each other and is vital for the whole microsystem. We offer and analyse the physical models among multiple micromotors concerning the cooperative and interactive modes in the lower and higher frequency ranges, respectively, between which the state transformation can reversibly occur. Furthermore, based on the proposed reversible microsystem, the feasibility of the application of self-organization is verified by demonstrating three different dynamic self-organizing behaviours. Our proposed dynamically reversible system has great potential to serve as a paradigm for studying cooperative and interactive behaviours among multiple micromotors in the future.

Multi-stage hybrid evolutionary algorithm for multiobjective distributed fuzzy flow-shop scheduling problem.

In the current global cooperative production mode, the distributed fuzzy flow-shop scheduling problem (DFFSP) has attracted much attention because it takes the uncertain factors in the actual flow-shop scheduling problem into account. This paper investigates a multi-stage hybrid evolutionary algorithm with sequence difference-based differential evolution (MSHEA-SDDE) for the minimization of fuzzy completion time and fuzzy total flow time. MSHEA-SDDE balances the convergence and distribution performance of the algorithm at different stages. In the first stage, the hybrid sampling strategy makes the population rapidly converge toward the Pareto front (PF) in multiple directions. In the second stage, the sequence difference-based differential evolution (SDDE) is used to speed up the convergence speed to improve the convergence performance. In the last stage, the evolutional direction of SDDE is changed to guide individuals to search the local area of the PF, thereby further improving the convergence and distribution performance. The results of experiments show that the performance of MSHEA-SDDE is superior to the classical comparison algorithms in terms of solving the DFFSP.

Toward a Cooperative ADAS for Train Driving based on Real-Time Human Parameters and Delay Estimation

Modern railway research focuses on autonomous train control systems, however the existing rolling stock still requires human driver in the control loop, especially for safety critical operations. This article is about the interaction of the train driver and an autonomous driver advisory system (ADAS) based on human state estimation to avoid confrontative and encourage integrative cooperation modes. This is made possible using a special observer design approach that allows to estimate driver's reaction delay to ADAS advises, and to reconfigure the ADAS mode accordingly. The result is that the driver acceptance rates (for ADAS suggestions) improve, along with the overall train control performance, ensuring successful mission. Theoretical developments and simulation results are provided.

Dual-prodrug cascade activation for chemo/chemodynamic mutually beneficial combination cancer therapy.

The combination of chemodynamic therapy (CDT) and chemotherapy has shown promise for achieving improved cancer treatment outcomes. However, due to the lack of synergy rationale, a simple one-plus-one combination therapy remains suboptimal in overcoming the obstacles of each treatment approach. Herein, we report a nanoplatform consisting of a pH-sensitive ferrocene- and cinnamaldehyde-based polyprodrug and a hydrogen peroxide-responsive doxorubicin (DOX) prodrug. Under an acidic tumor environment, the cinnamaldehyde polyprodrug will be activated to release free cinnamaldehyde, which can increase the intracellular hydrogen peroxide level and enhance the Fenton reaction. Subsequently, due to the collapse of nanoparticle structures, the DOX prodrug will be released and activated under a hydrogen peroxide stimulus. Meanwhile, the quinone methide produced during DOX prodrug activation can consume glutathione, an important antioxidant, and thus in turn enhance the efficacy of CDT. This design of a nanoplatform with dual-prodrug cascade activation provides a promising mutually beneficial cooperation mode between chemotherapy and CDT for enhancing antitumor efficacy.

Risk Identification from the Perspective of South-South Cooperation —Evidence from China and Mongolia Agricultural Technology Cooperation

Continuous growth, the transformation of animal husbandry, and economic policy offer substantial opportunities for agriculture development, alleviate poverty, food security gains, improve human nutrition, and grow the agriculture economy. In Mongolia, successive governments have brought revolutionary changes to establish the planting industry in the region. The Mongolian government vigorously implemented a "land reclamation" policy three times to promote and develop the plant industry. Plant industry is the only viable livelihood option for the impoverished Mongolian people. Therefore, South-South Cooperation agricultural technology transfer project is a significant component of China's international agricultural cooperation and assistance. It has carried out many exemplary agricultural projects to improve agriculture development and animal husbandry in Mongolia, positively enhancing agriculture productivity. Therefore, this article aims to analyze the modes, achievements, and risks critically. This introductory article examined the existing difficulties and risks related to the dairy cow, sheep, and freshwater fisheries in China and Mongolia during 2000-2020. It concluded that lack of supply chain cooperation and unsustainability are significant problems. Finally, this study provides guidelines to promote the agricultural economy, technology, and market mechanisms to gain the mutual benefit of economic and trade cooperation. This study suggests transforming the existing single project-driven cooperation mode of government and enterprises into a deepen corporation by multiple projects in agriculture, animal husbandry, technological management, metrology, crops, and veterinary medicine. Moreover, to increase renewable energy, the government should support, cooperate, and implement the “One Billion Trees" campaign as part of the "Recovery Policy" to mitigate climate change.

Quality Inspection Method of Agricultural Products Based on Image Processing

Farmers should provide high-quality agricultural products and companies should receive high-quality agricultural products, which is the purpose and pursuit of the business model of "companies plus farmers". In order to increase the stability of the cooperation mode between companies and farmers, it is necessary to detect the quality of agricultural products accurately, objectively and efficiently. Therefore, this article studies the quality inspection method of agricultural products based on image processing. Firstly, the traditional threshold calculation method and threshold function are improved to obtain more ideal denoising effect of agricultural products images. Aiming at the problem that the traditional image processing model cannot obtain fine-grained feature information of image objects, a multi-level feature dependence extraction network is constructed, and the structure and working principle of the network model are introduced in detail. Experimental results verify the effectiveness of the proposed algorithm and model for agricultural product quality inspection.

A long way for the popularization and improvement of burn rehabilitation

In more than half a century, burn rehabilitation in China has experienced three periods: initial exploration in the latter half of the 20th century, gradual development in the first decade of the 21st century, and the accelerating popularization in the recent decade. Looking back at the historical development of burn rehabilitation, we can see not only great progresses, but also many problems and deficiencies. In China, many units still do not even provide burn rehabilitation treatment, and many units where rehabilitation is also in practice, are commonly experiencing problems such as lack of enough therapists, insufficient team construction and training, incomplete treatment programs and limited curative effects, unstable multi-disciplinary cooperation mode, and lack of high-level rehabilitation research and technological innovation. Based on this, this paper puts forward some suggestions for further development and improvement, hoping to push the burn rehabilitation in China from popularization towards a comprehensive high level.

A novel structural–functional integration piezoelectric thruster for miniature unmanned underwater vehicles

Unmanned underwater vehicles (UUVs) play a vital role in marine exploration, and can achieve an extension of human hands and eyes to help researchers reach inaccessible and complex underwater spaces. However, the developed UUVs are driven by electromagnetic motors that also make it difficult to miniaturize due to the existence of the transmission system. Additionally, electromagnetic motors need to be protected to against water intrusion, especially in the deep sea. Therefore, in order to solve the above-mentioned problems, a novel structure-functional integration piezoelectric thruster for miniature UUVs is proposed in this study. Based on the converse piezoelectric effect and the direct friction drive principle, rudders and propellers can be alternately driven by a piezoelectric actuator, constructing the thrust unit and the steering unit of the piezoelectric thruster, respectively. Therefore, this makes the structure and function of the piezoelectric thruster integrated. Finite element simulations are first conducted to determine the geometrical sizes of the proposed actuator. The efficiency of the designed piezoelectric actuator is then confirmed using an underwater vibration measurement. Finally, experimental evaluations of the output performance of the piezoelectric thruster are performed. In the propulsion mode, the maximum rotation speed and thrust of the positive and negative propeller of the prototype with an excitation voltage of 600 Vpp were 404 rpm/0.10 N and 413 rpm/0.11 N, respectively. In the cooperative working mode, 20.00 kHz was used as the driving frequency, and the yaw and pitch rudders had the maximum average angle velocities of 92 deg s−1 and 90 deg s−1 for an excitation voltage of 600 Vpp, respectively. The maximum rotation speed and thrust of the positive and negative propellers of the prototype with an excitation voltage of 600 Vpp were 133 rpm/0.01 N and 132 rpm/0.01 N, respectively. According to experimental findings, the prototype piezoelectric thruster exhibits excellent mechanical properties.

Decision-making of active collision avoidance system based on comprehensive evaluation method of dangerous scenarios

Dangerous scenario modeling is of great significance for the development of automatic driving functions, and the active collision avoidance system directly affects the safety of vehicles and the intelligence level of vehicles. However, the current existing collision risk evaluation methods are difficult to comprehensively evaluate different dangerous scenarios, the evaluation methods are complicated and there is no normalized description form. In addition, the traditional decision-making method of active collision avoidance system based on collision time distance will lead to the problems of inconsistent risk evaluation scale and single way of collision avoidance. To solve the above problems, the mechanism analysis of the longitudinal, lateral, and parallel collision risks is carried out respectively, and then the model based on kinematics and dynamics is established. After that, the corresponding expression form of collision risks is derived. Finally, the comprehensive evaluation method of dangerous collision scenarios is proposed. Secondly, based on the comprehensive evaluation method of collision risk, considering longitudinal constraints, lateral constraints, parallel constraints, and road regulations, an active collision avoidance decision-making method that used the cooperative collision avoidance mode of breaking and steering is designed. Thirdly, different simulation experiments are designed based on PanoSim/Simulink. The results show the comprehensive evaluation method can effectively model the collision risk of vehicles in the motion process. At the same time, the decision-making method of the active collision avoidance system achieves the expected working effect, thus improving driving stability and safety.

The task coordination method of intelligence‐alliance innovation team of universities in Western China

AbstractTo resolve the dilemma among a shortage of high‐end talents, low level of scientific research and a huge brain drain in western universities in China, we proposes a way out by building an intelligence‐alliance innovation team—a new interregional and multiagent cooperation mode. We identify major disagreements that hamper a fruitful collaboration, and then analyze reasons of such poor coordination. Given diversified backgrounds and different preferences of intelligence‐alliance innovation teams, we suggest multiagent group decision‐making as a method of seeking task coordination for participants in conflict and their problem‐solvers. Finally, a specific case is given to prove that this method can improve task coordination of intelligence‐alliance innovation teams, and that holistic feedback coordination may be the best scheme of task coordination for intelligence‐alliance innovation teams.

Network Analysis Measuring the Impact of Volcanic Eruptions

Volcanoes can be extremely damaging to the environment, human society, and also impact climate change. During volcanic eruption, massive amounts of gases and dust particles are thrown into the atmosphere and propagated instantaneously by the stratospheric circulation, resulting in a huge impact on the interactive pattern of the atmosphere. Here, we develop a climate network-based framework to study the temporal evolution of lower stratospheric atmosphere conditions in relation to a volcanic eruption, the Hunga Tonga-Hunga Ha’apai (HTHH) volcano, which erupted on 20 December 2021. Various spatial-temporal topological features of the climate network are introduced to analyze the nature of the HTHH. We show that our framework has the potential to identify the dominant eruption events of the HTHH and reveal the impact of the HTHH eruption. We find that during the eruption periods of the HTHH, the correlation behaviors in the lower stratosphere became much stronger than during normal periods. Both the degree and clustering coefficients increased significantly during the dominant eruption periods, and could be used as indications for the eruption of HTHH. The underlying mechanism for the observed cooperative mode is related to the impact of a volcanic eruption on global mass circulations. The study on the network topology of the atmospheric structure during a volcanic eruption provides a fresh perspective to investigate the impact of volcanic eruptions. It can also reveal how the interactive patterns of the atmosphere respond to volcanic eruptions and improve our understanding regarding the global impacts of volcanic eruptions.
