Abstract

Objective To compare the safety and efficacy of transurethral laser and transurethral resection for treatment of non-muscle invasive bladder cancer (NMIBC). Methods Randomized controlled trials, cohort studies and case-control studies comparing transurethral laser and transurethral resection of NMIBC were retrieved from PubMed, Medline, Embase, Cochrane Library, Web of Science, Social Science Citation Index, China Journal Full-text Database (CNKI), Chinese Biomedical Literature Database and VIP medical database. RevMan 5.3 software was used for meta-analysis of the data extracted from the eligible studies. Results We retrieved 16 eligible studies involving a total of 2 570 patients from the databases. Meta-analysis of the data from these studies showed no significant difference between the 2 surgical modalities in terms of the operation time (MD=-0.70, 95%CI: -2.78~1.38, P=0.51) or the occurrence of postoperative urethral stricture (OR=0.70, 95%CI: 0.24~2.06, P=0.52). Compared with transurethral resection, transurethral laser surgery was associated with significantly lower incidences of intraoperative obturator nerve reflex (OR=0.05, 95%CI: 0.02~0.10; P < 0.001) and bladder perforation (OR=0.11, 95%CI: 0.04~0.29, P < 0.001), shorter postoperative catheterization time (MD=-1.08, 95%CI: -1.46~-0.71, P < 0.001) and length of hospital stay (OR=0.05, 95%CI: 0.02~0.10, P < 0.001), and lower rates of bladder irrigation (OR=0.21, 95%CI: 0.13~0.35, P < 0.001) and postoperative recurrence at 12 months (OR=0.67, 95%CI: 0.48~0.93, P=0.02) and 24 months (OR=0.60, 95%CI: 0.41~0.86, P=0.005). Conclusion Transurethral laser surgery for NMIBC, as compared with transurethral resection, is associated with lower incidences of intraoperative complications (obsessive nerve reflex and bladder perforation), a lower postoperative recurrence rate, and faster postoperative recovery.

Abstract

This research introduces a novel, highly precise, and learning-free approach to locomotion mode prediction, a technique with potential for broad applications in the field of lower-limb wearable robotics. This study represents the pioneering effort to amalgamate 3D reconstruction and Visual-Inertial Odometry (VIO) into a locomotion mode prediction method, which yields robust prediction performance across diverse subjects and terrains, and resilience against various factors including camera view, walking direction, step size, and disturbances from moving obstacles without the need of parameter adjustments. The proposed Depth-enhanced Visual-Inertial Odometry (D-VIO) has been meticulously designed to operate within computational constraints of wearable configurations while demonstrating resilience against unpredictable human movements and sparse features. Evidence of its effectiveness, both in terms of accuracy and operational time consumption, is substantiated through tests conducted using open-source dataset and closed-loop evaluations. Comprehensive experiments were undertaken to validate its prediction accuracy across various test conditions such as subjects, scenarios, sensor mounting positions, camera views, step sizes, walking directions, and disturbances from moving obstacles. A comprehensive prediction accuracy rate of 99.00% confirms the efficacy, generality, and robustness of the proposed method.

197. MgO-Based Granular Sorbent Pelletized by Using Ordered Mesoporous Silica as Binder for Low-Temperature CO2Capture

Author

Abstract

Cyclic CO2adsorption by using MgO as a sorbent at low temperatures is considered a promising route for postcombustion CO2capture. However, most MgO-based sorbents are in the form of fine powder and cannot be used in a fluidized bed reactor, and at the same time, suffer from a rapid loss in CO2uptake capacity due to the decrease of surface area aroused by pore shrinking and grain sintering. In this study, mesoporous silicas with highly ordered pore structures have been used as binders, for the first time, to fabricate MgO-based sorbent pellets via a simple and scalable extrusion–spheronization approach. The obtained MgO-based pellets exhibit high porosity attributed to the nature of the mesoporous binder, leading to a significantly increased stability and CO2uptake capacity. Especially for the low-concentration CO2that is comparable to the flue gas from a coal-fired power plant, the results show that the ordered mesoporous silica binder provides a remarkable promotion effect and excellent stability in the capture performance. The CO2uptake capacity of the best-performing sorbent, 20-KIT-6–100, displays a small decline of 6.86% (from 1.02 mmol of CO2/g in the first cycle to 0.95 mmol of CO2/g in the 10th cycle). It is envisaged that mesoporous materials hold great potential to be used as binders in reinforcing the metal oxide-based sorbents for flue-gas CO2capture in practical applications.

Abstract

Piezoelectric traveling-wave microactuator based on microelectromechanical systems (MEMSs) technology has the advantages of miniaturization and easy to integrate. However, the lack of angle sensing function limits their application in the aspect of microstructural rotation closed-loop control. Here, we present a self-sensing piezoelectric traveling-wave microactuator. By integrating the capacitive encoder with the microactuator, high-precision step angle rotation can be achieved, facilitating rotation closed-loop control of various MEMS microstructures. The prototype size of the self-sensing microactuator is $5 \times 5$ mm. The angle detection accuracy and the resolution can reach up to 0.06° and 0.01°, respectively, which ensures the microacutor complete adaptive angle adjustments. This work is expected to pave a new way for in situ calibration of inertial sensors, microrobot movement, control of optical devices, and light path manipulation.

199. Low-Complexity Output Feedback Control With Prescribed Performance for Bioinspired Cable-Driven Actuator

Author

Wang, Zezheng, Zhou, Zhihao, Xu, Ming, Mai, Jingeng, and Wang, Qining

Abstract

This article addresses the modeling and control of bioinspired cable-driven actuator that can mimic the three activation modes of human muscles. First, the dynamic model of the actuator is established by utilizing the coordinate transformation and kinetic energy theorem for controller and observer design. Then, a low-complexity output feedback controller with prescribed performance is proposed, so that the driving disc can track the rotation of the cable pulley without overshoot during the operation of the actuator. Specifically, the collision caused by overshoot during the tracking process must be avoided, as it can cause a sudden change of the cable tension, impact noise, and even mechanical parts damage. The presented low-complexity control strategy guarantees that the tracking error does not violate the predefined performance constraint and can converge to a predetermined residual set in finite time by introducing a novel error transformation function and a performance function. In addition, to avoid using angular velocity sensor, a finite-time observer with interval type-2 fuzzy system and adaptive technique is developed to estimate the angular speed of the driving disc. Finally, simulation studies and prototype experiments are performed to validate the effectiveness of the proposed control scheme on the bioinspired actuator.

200. Bioinspired Cable-Driven Actuation System for Wearable Robotic Devices: Design, Control, and Characterization

Author

Xu, Ming, Zhou, Zhihao, Wang, Zezheng, Ruan, Lecheng, Mai, Jingeng, and Wang, Qining

Abstract

Wearable robotic devices interact with humans by applying the assistive force in parallel with muscle–tendon systems. Designing actuations in mimicking the natural activation patterns of human muscles is a promising way to optimize the performance of wearable robots. In this article, we propose a bioinspired cable-driven actuation system capable of providing anisometric contractions (including concentric and eccentric contraction) assistance or nearly acting as a transparent device in an efficient manner. A novel clutch–spring mechanism is employed to accomplish switches between assistive modes and the transparent mode. Corresponding control strategies coordinating with the mechanical design were presented and described in detail. Multiple evaluations were conducted on a test bench to characterize the system's performance. The closed-loop bandwidth of the system running concentric assistance control was 18.2 Hz. The R-squared values of linear fitting under eccentric assistance control were above 0.99. The engagement time of the proposed clutch was about 90 ms. Applying the actuation to an ankle exoskeleton, multiple walking experiments with electromyography measurements were performed on five subjects to show its application potential in existing wearable robots. Experimental results revealed that the proposed design could reduce soleus muscle activity by 27.32% compared with normal walking. This study highlights the importance of functional bionic design in human-assistance-related devices and introduces a general actuation system that could be directly applied to existing cable-driven wearable robots.
