This article presents a composite nonlinear feedback (CNF) control method using self-triggered (ST) adaptive dynamic programming (ADP) algorithm in a human-machine shared steering framework. For the overall system dynamics, a two-degrees-of-freedom (2-DOF) vehicle model is established and a two-point preview driver model is adopted. A dynamic authority allocation strategy based on cooperation level is proposed to combine the steering input of the human driver and the automatic controller. To make further improvements in the controller design, three main contributions are put forward. Firstly, the CNF controller is designed for trajectory tracking control with refined transient performance. Besides, the self-triggered rule is applied such that the system will update in discrete times to save computing resources and increase efficiency. Moreover, by introducing the data-based ADP algorithm, the optimal control problem can be solved through iteration using system input and output information, reducing the need for accurate knowledge of system dynamics. The effectiveness of the proposed control method is validated through Carsim-Simulink co-simulations in diverse driving scenarios. © 2025 IEEE. All rights reserved.

Achieving the complete adsorption of phosphorus-containing organics from the complex wastewater generated during the recycling process of waste batteries is a critical environment challenge. The research findings of this work reveal that in complex solution systems, ions can significantly alter the hydrophilicity or structural morphology of phosphorus-containing organic compounds, thereby influencing their adsorption efficacy. Based on these insights, an innovative adsorption strategy based on ion-regulation was proposed for the complete removal of phosphorus-containing organics from complex wastewater. By precisely modulating the concentration of H3O+ ions within actual cobalt extraction wastewater prior to the adsorption process, we achieved a removal rate exceeding 99.98% for phosphorus-containing organics. This breakthrough offers innovative perspectives for the comprehensive removal of organic pollutants in complex wastewaters within the waste battery recycling sector and provides important guarantees for the industry’s environmental health and sustainable development. © 2025, The Authors.

Controlling the molecular weight (Mw) of oligosaccharides in an enzymatic conversion process is a challenge in the production of intermediate-sized oligosaccharides. The enzymatic membrane reactor (EMR) with immobilized enzymes is proposed as a strategy to improve production of the intermediate-sized oligosaccharides. The immobilized enzymes catalyze reactions near the membrane surface, and the target molecules can be immediately separated from the enzymes once they reach the desired size. Hence, EMRs with immobilized enzymes enable better control on the product quality. However, immobilizing enzymes directly on the membrane surface usually causes inevitable membrane fouling and reduces the membrane separation performance. In this study, we proposed a novel configuration of EMR that contains a porous 3-D fibrous layer, that was produced via electrospinning, a porous mechanical support layer on top and a commercial separation membrane on the bottom. Polydopamine (PDA), tannic acid (TA) and (3-Aminopropyl) triethoxysilane (APTES) were firstly used to modify electrospun fibers to offer binding sites for enzyme immobilization. Then the enzymes were filtrated through the 3-layer structure for the immobilization. In comparison to the incubation-immobilized enzymes (produced 0.075 µmol-isomaltose/min), the ‘fouling-induced’ enzyme immobilization proposed here significantly increased the immobilized enzyme activity up to 11.5 µmol-isomaltose/min. Moreover, the extra layer on the membrane surface preserved the desired catalytic pattern of the enzymes, and reduced membrane fouling caused by the enzymes, and thus the membrane preserved high selectivity towards the oligosaccharides products. In the production of low Mw oligosaccharides, due to the high enzyme activity (up to 11.3 µmol-isomaltose per minute) on the catalytic layer and excellent selectivity of the membrane, stable Mw of oligosaccharides were obtained, which indicates a successful high-performance EMR.

This paper proposes SaleNet - an end-to-end convolutional neural network (CNN) for sustained attention level evaluation using prefrontal electroencephalogram (EEG). A bias-driven pruning method is proposed together with group convolution, global average pooling (GAP), near-zero pruning, weight clustering and quantization for the model compression, achieving a total compression ratio of 183.11x. The compressed SaleNet obtains a state-of-the-art subject-independent sustained attention level classification accuracy of 84.2% on the recorded 6-subject EEG database in this work. The SaleNet is implemented on a Artix-7 FPGA with a competitive power consumption of 0.11 W and an energy-efficiency of 8.19 GOps/W. Copyright © 2022, The Authors. All rights reserved.

The separation of 1,2,4-butanetriol (BT) through phenylboronate anion reactive extraction in fermentation broth has been proposed based on the process where the boronic acid groups specifically recognize the cis-dihydroxyl groups. To fully elucidate the affinity process of boronic acid group and polyols, here we have investigated the binding constant (Ka) and thermodynamic data of four phenylboronic acid derivates (PBADs) and four structurally similar linear polyols (BT, 1,2-butanediol (1,2-BD), 1,3-butanediol (1,3-BD), and 1,4-butanediol (1,4-BD)) through fluorescence spectroscopy, isothermal titration calorimetry (ITC), and computational chemistry. It can be concluded that the substituent group of boronic acid, the numbers and relative positions of the hydroxyl group in polyols affected the affinity of the boronic acid group to it. The ionized boronic acid group preferentially reacts with the 1,2-dihydroxy group to form a pentacyclic phenylboronate. Compared with other three butanediols, phenylboronic acid (PBA) has a larger binding constant and shows a smaller Gibbs free energy change with BT. © 2023, The Authors. All rights reserved.

Uniaxial and multiaxial ratcheting tests of zirconium cladding tubes with constant internal pressure and cyclic axial loading were conducted at 648 K, aiming to investigate the influences of axial mean stress, stress amplitude, and inner pressure. Anomalous ratcheting behaviors were observed, including negative axial ratcheting strain accumulation under symmetric uniaxial cyclic loading conditions and significant changes in ratcheting strain direction under certain multiaxial loading conditions. Isotropic phenomenological constitutive models based on the Armstrong-Frederick kinematic hardening rules were found to be insufficient in predicting such behaviors by a geometric interpretation method. A generalized form of dynamic recovery terms was proposed to improve the flexibility in predicting multiaxial cyclic behaviors. Based on this scheme, a kinematic hardening model incorporating the influences of the twinning-detwinning mechanism on cyclic plasticity was formulated. The simulations of the proposed model show acceptable agreement with the test results. © 2024, The Authors. All rights reserved.

This study aimed to produce high-performance dissolving pulps from corn stalks using a combination of Cold caustic extraction (CCE) and deep eutectic solvent (DES) method. Results showed that CCE not only removed hemicellulose but also altered the structure of cellulose, increasing its polymerization degree and influencing the Fock reactivity of the dissolving pulp (reduced to 10.55%). Subsequent treatment with DES effectively dissolving the remaining hemicellulose while disrupting the cellulose crystallinity and improving the Fock reactivity of the dissolving pulp (increased to 72.14% from 10.55%). The study implied that the hydrogen bond donor in DES played a crucial role in breaking the cellulose chains and improving the reactivity of the dissolving pulp. The dissolving pulp produced from corn stalks using through the combination of CCE and DES method exhibited the cellulose content of 94.46% and the Fock reactivity of 72.14%, surpassing the traditional prehydrolysis kraft-based dissolving pulps from wood, providing a new strategy for the high-value utilization of stover resources. © 2023, The Authors.
