The efficiency and quality of tobacco leaf harvesting are crucial for the economic performance of the tobacco industry. To enhance harvesting efficiency, a non-destructive tobacco leaf harvesting robot based on machine vision and robotics technology was developed. Experimental evaluations of key components demonstrated that the biomimetic flexible gripper based on the fin ray effect has good stiffness when the clamping force is 2.5 N, ensuring stable subsequent harvesting and collection of tobacco leaves. The introduction of a 6+1-axis robotic arm significantly expands the working range compared to the original 6-axis design, effectively covering the height of the tobacco stalk. The robotic arm’s speed notably affects harvesting time (P © (2025), American Psychological Association

The rapid advancement of flexible electronics has unlocked opportunities across diverse fields, including medical science and device engineering. Developing flexible three-dimensional integrated circuits (3D ICs) is a key strategy for driving the miniaturisation, wearability and multifunctionality of flexible devices. Among these innovations, liquid metal-based flexible electronics have elicited significant attention due to their exceptional conductivity, high stretchability and low toxicity. This review highlights recent research breakthroughs in the application of liquid metal for flexible 3D ICs, providing a detailed discussion of the design concepts and strategies for patterning and interconnection structures that harness the unique properties of liquid metal. Using 3D printing technology to fabricate high-resolution, durable 3D ICs from liquid metal represents a major research direction. Moreover, advanced fabrication methods diverging from conventional 3D printing systems are explored. Finally, we examine persistent challenges and offer a forward-looking perspective on the potential of liquid metal-based flexible 3D ICs to revolutionise human–machine interactions and enable intelligent living.

Memristors with threshold transition behavior and rich dynamics are ideal candidates for simulating biological pulse neurons and constructing efficient neuromorphic systems. Based on changes in material structure, charge distribution, molecular polarization and other physical states, new integrated memory-computing devices have been constructed and applied to the sensor-memory-computing integrated systems. In this review, we first discuss the classification of memristive materials from the perspective of device structure design and focus on introducing the working mechanisms of valence variation, polarization, and carrier transfer covered internally. Further, the latest progress of memristors with multi-physical mechanisms is comprehensively summarized, including the formation/fracture of conductive filaments, carrier capture/release, polarization/depolarization. In particular, it is discussed in detail the principles and applications of memristors with different working mechanisms for constructing neuromorphic systems. Finally, the potential challenges and opportunities that may exist in the development of memristors in the coming years are discussed in depth. © 2025 Elsevier Ltd

In recent years, as people’s living standards have improved and consumption concepts have been transformed, the demand for purchasing consumer electronics online has continued to grow, further stimulating the development of the logistics industry. Consequently, how to deliver consumer electronics to households at minimal cost has become a crucial factor that limits the development of the consumer technology industry. To tackle this problem, this paper studies the task assignment problem for multiple initially dispersed UAVs to deliver products to target locations while minimizing their total operation time. Each UAV can continuously provide delivery services to multiple target locations within its limited loading capacity and operation time. To solve this problem, we propose several hybrid multipopulation genetic algorithms. First, a novel crossover operator for the genetic algorithms is designed, through which a single parent chromosome can generate offspring individually. Second, two mutation mechanisms are performed to increase gene diversity. Third, multiple local search strategies are employed to enhance the populations’ fitness during each iteration of evolution. An improved 2-opt local search strategy is applied to optimize individual chromosomes when their similarity with the current best chromosome falls below a prescribed threshold. Alternatively, local search strategies are utilized for 1-opt, 2h-opt and interchange processes. Combining local search strategies, genetic operators, and the multi-population mechanism leads to several hybrid multi-population genetic algorithms. Numerical simulations and experimental tests demonstrate that the hybrid multi-population genetic algorithm, integrated with the improved 2-opt and 1-opt local search strategies, exhibits superior performance among the designed hybrid genetic algorithms, the minimum marginal cost algorithm (MMA), and the existing popular Co-evolutionary Multi-population Genetic Algorithm (CMGA).

Background::Streptococcus suis ( S. suis) can be transmitted to humans through exposure to pigs or consumption of raw pork and causes serious diseases. Although infection through skin abrasions is considered an important route of transmission, few studies have reported skin injuries in patients during exposure or before infection. This study explored a rare instance of intraocular infection and bilateral deafness caused by S. suis and emphasized the importance of timely diagnosis and treatment to prevent disease progression. Methods::The diagnosis was made on the basis of clinical symptoms, imaging, molecular detection, and isolated culture methods. Drug susceptibility testing was conducted to determine the effectiveness of antibiotics. Whole-genome sequencing was used to identify the strain’s sequence type and serotype as well as the presence of pathogenicity islands (PAIs).Results::A patient with intraocular infection and bilateral deafness was diagnosed with an S. suis infection. The infection was hypothesized to result from interspecies transmission due to the patient’s occupation and recent skin damage. The isolated strain was sensitive to ampicillin, ceftriaxone, vancomycin, linezolid, levofloxacin, and meropenem. Whole-genome sequencing revealed that the strain belonged to sequence type 353 and serotype 2, showing close similarity to strains isolated from wild boars in Chinese provinces. The strain lacked the 89 complete kb PAI but had a 33 kb PAI with high similarity, potentially indicating variable virulence. Conclusion::This study highlights the importance of employing multiple diagnostic strategies for the timely identification and treatment of S. suis infections. The presence of a potentially less virulent strain emphasizes the need for continuous surveillance and monitoring of emerging S. suis infections, particularly in Asian countries with high-risk populations associated with the pig farming industry.

The paper primarily investigates the fixed-time consensus problem of multi-agent systems (MAS) with impulsive effect. We firstly present a novel and suitable fixed-time protocol to solve the fixed-time consensus problems of MAS with impulsive effect. Under the control protocol, it is theoretically demonstrated that fixed-time consensus of MAS could be legitimately solved. Finally, some numerical simulations are given to verify the feasibility and effectiveness of the theoretical results. © 2018 IEEE.
