Abstract ：
Abdominal and intrauterine adhesions are common postoperative problems that can cause serious complications. Current adhesives are usually double sided and suffer from poor wet adhesion, nondegradability, and monofunctionality, which limits their application in preventing postoperative adhesions. Herein, a bioinspired microstructured Janus bioadhesive, named OD/GM@PG, with a wet adhesive inner layer and an antiadhesive outer layer is prepared by combining electrostatic spun and adhesive materials. By using both capillary suction and a catechol-based strategy, the wet adhesive strength and interfacial toughness of the Janus bioadhesive reach 98 kPa and 325 J m-2, respectively, which are much higher than those of commercial fibrin glues and cyanoacrylate glues. The electrostatic spun outer layer acts as a physical barrier with antiadhesive and friction-reducing effects. Additionally, the Janus bioadhesive demonstrates biodegradable, hemostatic, antioxidative, anti-inflammatory, and prohealing properties. In vivo results show that the asymmetric adhesion effect of the Janus bioadhesive effectively preventing postoperative abdominal and intrauterine adhesions. Notably, tandem mass tags-labeled quantitative proteomics analysis demonstrate that the expression of inflammatory response-associated proteins (S100A8, S100A9) is associated with adhesion; the Janus bioadhesive significantly downregulates this expression. Therefore, the OD/GM@PG Janus bioadhesive is a promising candidate for preventing postoperative adhesions. A bioinspired microstructured Janus bioadhesive with an asymmetric structure and adhesion behavior is prepared by combining electrostatic spinning and adhesive materials. By employing capillary suction and a catechol-based strategy, the Janus bioadhesive exhibits impressive wet adhesive strength and interfacial toughness. Furthermore, the asymmetric adhesion effect of the Janus bioadhesive effectively alleviates postoperative abdominal and intrauterine adhesions. image

Abstract ：
Cardiovascular disease is becoming the leading cause of human mortality. In order to address this, flexible continuum robots have emerged as a promising solution for miniaturizing and automating vascular interventional equipment for diagnosing and treating cardiovascular diseases. However, existing continuum robots used for vascular intervention face challenges such as large cross-sectional sizes, inadequate driving force, and lack of navigation control, preventing them from accessing cerebral blood vessels or capillaries for medical procedures. Additionally, the complex manufacturing process and high cost of soft continuum robots hinder their widespread clinical application. In this study, we propose a thermally drawn-based microtubule soft continuum robot that overcomes these limitations. The proposed robot has cross-sectional dimensions several orders of magnitude smaller than the smallest commercially available conduits, and it can be manufactured without any length restrictions. By utilizing a driving strategy based on liquid kinetic energy advancement and external magnetic field for steering, the robot can easily navigate within blood vessels and accurately reach the site of the lesion. This innovation holds the potential to achieve controlled navigation of the robot throughout the entire blood vessel, enabling in situ diagnosis and treatment of cardiovascular diseases.

Abstract ：
The traditional pneumatic soft actuator offers significant advantages, including high output force and strong deformation capabilities, making it widely utilized in soft robotics. Building on this foundation, a phase change drive mechanism addresses the size and weight issues associated with pneumatic actuators, but it also results in prolonged working times. In this paper, we propose a method for manufacturing a chamber using PVA 3D printing and design an electrothermal soft actuator featuring a double multichamber structure driven by the principles of phase change. The actuator utilizes phase transformation to generate air pressure, which enhances the recovery speed and expands the working range through the antagonistic effect. Under low voltage (<8 V), the average deformation rate of the actuator designed in this paper is increased by more than 50% through the antagonistic effect of the double multicavity structure, which effectively improves the actuator's overall efficiency. In addition, the actuator can achieve a unilateral deformation of 18.7 mm and generate a load output force of 540.7 g while weighing only 15.8 g.

Abstract ：
Low-dimensional nanomaterials are receiving widespread attention as one ideal material for manufacturing high-performance electronic switches, which play an important role in improving the reliability, working speed and miniaturization of electron devices. This article reviews 16 classes of low-dimensional nanomaterials used to prepare or refine micro-/nanoelectromechanical switches, molecular electrical switches, resistive switches for memory, molecular switches, spin switches and radio frequency switches. By classifying the size difference into zero-dimensional (0D) nanomaterials, one-dimensional (1D) nanomaterials and two-dimensional (2D) nanomaterials, the effect of nanomaterials on the switching performance and the progress of application in related electronic devices are reviewed. By comparison, we discovered the advantages of low-dimensional nanomaterial-based electronic switches compared to conventional semiconductor switches. Finally, the development direction, challenges and opportunities of low-dimensional nanomaterials for improving electronic device performance are presented, and future research directions are predicted.

Abstract ：
In recent years, designing a soft robot that can jump continuously and quickly explore in a narrow space has been a hot research topic. With the continuous efforts of researchers, many types of actuators have been developed and successfully employed to actuate the rapid locomotion of soft robots. Although these mechanisms have enabled soft robots with excellent movement capabilities, they largely rely on external energy supply cables, which greatly limits their applications. Therefore, it is still a big challenge to realize the unconstrained movement of the soft robot and the flexible adjustment of the movement direction in a narrow space. Here, a wireless magnetically controlled soft jumping robot with single-leg is proposed, which can achieve continuous and rapid jumping motion. What's more interesting is that by changing the frequency and waveform of the control signal, this soft robot can easily switch between forward and backward motions. This motion direction switching function enables the magnetically controlled soft robot to return to the initial position without adjusting the direction when it completes the operation in a narrow pipe or takes the wrong path, which greatly improves the motion efficiency of the soft jumping robot and broadens its application field.

Abstract ：
为了解决多目标跟踪（MOT）算法中由于模糊行人特征造成的身份切换（IDS）等跟踪问题，并验证行人外观在跟踪过程中的重要性，提出了一种基于中心点检测模型的注意力自相关网络（ASCN）。首先，对原图进行通道和空间注意力网络的学习以获得两种不同的特征图，并对深度信息完成解耦；然后，通过特征图之间的自相关性学习，获得更加准确的行人外观特征和行人方位信息，并将这些信息用于关联过程的跟踪；此外，制作了低帧率条件下视频的跟踪数据集，以验证改进算法的性能。在视频帧率条件不理想时，改进算法利用ASCN获取了行人外观信息，相较于仅利用方位信息的跟踪算法具有更好的准确率和鲁棒性。最后，将改进算法在MOT Challenge的MOT17数据集上进行测试。实验结果表明，与不加入ASCN的FairMOT(Fairness in MOT)相比，改进算法的跟踪平均准确率（MOTA）和识别F值（IDF1）指标分别提高了0.5和1.1个百分点，IDS数减少了32.2%，且在单卡NVIDIA Tesla V100上的运行速度达到了每秒21.2帧，这验证了改进算法不仅减少了跟踪过程中的错误，也提升了整体跟踪效果，且能够满足实时性要求。

Abstract ：
Traditional pneumatic soft actuators have been widely used in the field of soft robotics owing to their high output force and large deformation capabilities. However, their bulky pumping systems pose limitations on their portability and miniaturization. In this study, we propose a method of PVA film-assisted manufacturing chamber and design an electrothermal soft actuator based on a phase change material. The actuator makes the phase change material filled in the chamber change into the vapor phase by heating from the embedded electrothermal wire, thus driving the actuator to deform. The actuator designed in this article can achieve a unilateral deformation of 17 mm and an output force of 0.265 N at a voltage of 5 V (the weight of the actuator itself is 1.5 g). In addition, based on the absolute node coordinate method, we adopt the hyperelastic material model, which can well describe the large deformation behavior of this soft structure, to model the actuator.
