Squat gait is the most common abnormal gait in children with cerebral palsy. Gait training with lower limb rehabilitation robots can improve rehabilitation efficiency and reduce manual labor for them. A novel exoskeleton-based lower limb rehabilitation robot for children with cerebral palsy is proposed, considering the squat gait characteristics of children with cerebral palsy. The structure of the lower limb rehabilitation robot, which combines hip and knee with 4 active degrees of freedom exoskeleton and mobile walker, is designed and optimized. Static analysis of the key mechanical structure of the exoskeleton is conducted using ANSYS Workbench, and local structures are optimized to ensure the safety factor of the mechanical structure is greater than 1, guaranteeing reasonable structural strength and stiffness design. Dynamic simulation analysis based on the ADAMS model validates the reliability and dynamic walking effect of the lower limb exoskeleton rehabilitation robot, obtaining the curve relationship between joint angles and motion cycles, thus verifying the effectiveness of the mechanical system motion. © 2024 IEEE.

While polymerized whey finds wide application in dairy products, modifications to their molecular weight and gel structure can impact digestibility. Herein, we investigated a modified whey protein isolate (MWPI) by pre-heating with Transglutaminase to assess its digestibility, peptide profiles and satiety. Due to the high molecular weight and gel structure, it exhibited a slow digesting rate. Compared to WPI, MWPI yielded 103 peptides with greater abundance, including 17 predicted as ACE inhibitors and 1 as a DPP IV inhibitor. Visual analytics indicated the primarily differential peptides originated from WPI and MWPI located at distinct α-helix and β-sheet of β-lactoglobulin, α-lactalbumin and bovine serum albumin. Furthermore, the WMPI gavage extended stomach retention time in mice, decreased intestinal propulsion rate and enhanced the satiety within 120 min than WPI administration. Overall, whey polymerization modulates the protein-enzyme interactions, validating the release of different peptides from gel structure and enhancing of satiety. © 2024, The Authors.

Currently, the utilization of Fenton or Fenton-like reactions is prevalent in various domains such as environmental control, biology, and life science. In this study, we drew inspiration from the MoS2 cocatalytic heterogeneous Fenton system and devised a Z-scheme CNFe/MoS2 heterojunction. This heterojunction is connected through atomic-level Fe-S-Mo and Mo-N interfacial chemical bonds, serving as a catalyst for synergistic photocatalytic effects in conjunction with Fenton reactions. The utilization of dual reduction approaches involving photo-generated electrons and Mo4+ effectively facilitates the stable circulation of Fe3+/Fe2+ with high efficiency in an acidic microenvironment, which is facilitated by the S-SO42- edge of MoS2. The active centers for the Fenton reaction in CNFe/MoS2 are represented by the Fe-N3 and S-Fe-N3 moieties. Moreover, the CNFe/MoS2 Z-scheme heterojunction exhibits enhanced production of ∙O2 and H2O2, thereby demonstrating the photo-self-Fenton effect. This effect not only reduces the quantity of hydrogen peroxide generated but also contributes to cost reduction. This work not only experimentally verifies the coupling effect of Z-scheme heterojunction and cocatalytic heterogeneous Fenton system but also provides a new idea for the design of efficient advanced oxidation processes (AOPs). © 2023, The Authors.

Parameter-Sharing-Based Average-Consensus Time Synchronization in IoT Networks

Average-consensus protocol is one of the ways to develop distributed time-synchronization algorithms in Internet of Things (IoT) networks. However, the large number of iteration leads to a common time notion issue in nodes. This poses a critical challenge in the convergence of the time-synchronization algorithm and resulting asymptotic convergence in the average consensus protocol. In this article, a parameter-sharing-based average-consensus time-synchronization (PACTS) algorithm is proposed. For fast convergence, the proposed PACTS quickly forwards the time information to multihop nodes and employs multihop average-consensus instead of single-hop average consensus. Specifically, a node asynchronously and periodically broadcasts the relative clock offset estimation of neighbors with its local time information. Meanwhile, the relative clock offset estimation of the multihop node is calculated and used to estimate the average value. Consequently, an average consensus among local multihop nodes is obtained. As a result, the iteration number and convergence time are significantly reduced over the network. Finally, the experimental results indicate that the proposed PACTS algorithm has low complexity, high accuracy, and quick convergence. © 2023 IEEE.
