Identification of host factors that play a key role in viral replication is of great importance for antiviral development. Metabotropic glutamate receptor subtype 2(mGluR2) is the receptor to trigger clathrin-mediated endocytosis(CME), the major pathway by which influenza virus enters cells. However, other host factors almost certainly involved in the influenza virus CME are largely unknown. Here, we found that the four-transmembrane protein claudin-11 plays an integral part in influenza virus CME. Claudin-11 promotes the dissociation of KCa1.1(potassium calcium-activated channel subfamily M alpha 1) from mGluR2 and, together with mGluR2, is internalized in viruscontaining clathrin-coated pits(CCPs), where it regulates the depolymerization of polymerized F-actin, allowing the CCPs to ***, over 60% of claudin-11-silenced mice survived infection with a lethal influenza virus. Our findings advance the understanding of influenza virus infection and provide a promising strategy for the development of host-based antiviral drugs.

Curve-Suppression-Based Event-Triggered Mechanisms for Quasi-Synchronization of Fuzzy Delayed Neural Networks on Time Scales

IEEE Transactions on Systems, Man, and Cybernetics: Systems 2025年第5期55卷 3174-3187页

The vast majority of published event-triggered mechanisms (ETMs) are constructed based on measurement errors, which introduces a problem naturally that they are updated when the measurement errors exceed the thresholds although the current obtained sampling states can make systems converge well. With this problem in mind, we redesign ETMs for quasi-synchronization of T-S fuzzy neural networks (FNNs) with time delays on time scales. First, a novel ETM is designed for continuous-time FNNs with time-varying delays to achieve quasi-synchronization, with which synchronization errors is suppressed to globally exponentially converge to a ball. Second, we introduce the ETM for continuous-time FNNs to discrete-time FNNs, owing to the existence of discrete-time states, the Lypunov function of synchronization errors run over the exponentially decay curve, but it can be suppressed to evolve under another exponentially decay curve. Third, for FNNs on time scales with constant and time-varying delays, we estimate the forward jump operator of the Lyapunov functions and design ETMs to guarantee that the Lypunov functions evolve under the exponentially decay curves, so quasi-synchronization can be achieved. Last but not least, we prove that Zeno behavior will not happen and four numerical examples are introduced to verify the validity and the superiority of the proposed ETMs in reducing information transmission. © 2013 IEEE.

This work is aimed at analysing the optimal management by a producer who may redistribute the income to expand production or to pay dividends. There is external investment provided in the beginning and over the planning period of time these funds should be paid back to the external investor. The management problem is formulated as an optimal control problem with an inequality type constraint on both state and control. The necessary optimality conditions are analysed to find out the property of the solution. Numerical analysis of this problem is used to verify the properties of the solution. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

QR code is a commonly used two-dimensional barcode employed in a variety of applications. To simplify the detection and segmentation of QR code, its structure incorporates three finder patterns. Sometimes, code sides are cropped due to printing issues or overlapping. However, most recognition methods refuse to work if at least one of three finder patterns is missing or damaged. This paper proposes an approach that allows reading such codes. It is based on utilizing alignment patterns alongside with finder patterns and the RANSAC scheme to estimate a projective transform that maps the symbol modules to the input image. The effectiveness of the proposed approach is evaluated using the generated dataset called SE-QR-SYN-500. It simulates cropped QR codes, both with and without projective distortions, and is published for the open use. The existing open-source solutions show zero accuracy on this dataset. In comparison, our implementation of the proposed approach demonstrates 77.8% accuracy for straight QR codes and 76.4% accuracy for QR codes with projective distortions. Copyright © 2025 SPIE.

In this paper, we use deep reinforcement learning to enable connected and automated vehicles (CAVs) to drive in a intersection with human-driven vehicles. The multi-agent deep deterministic policy gradient (MADDPG) algorithm is improved to be more efficient for data processing, so that it can solve the problem of learning bottlenecks in complex environments, and use sliding control to execute control strategies. Finally, the feasibility of the method is verified in the simulation environment of CARLA. Copyright © 2025 by SCITEPRESS - science and Technology Publications, Lda.

The paper considers a mathematical model that describes the interactions between the economic system and the ecological system through waste emissions, resource consumption, and the restoration of restorable resources. It is assumed that the state levies a tax on waste emissions, thereby controlling emissions and the consumption of resources by the economy. The model also describes the impact of economic and environmental factors on demographics. The state should strive for economic growth and avoid environmental disasters, and the model can be useful for achieving these goals. Besides, a software implementation of the model was constructed. Some technical details of the software implementation were also considered. Numerical experiment with one of the possible sets of parameters’ values was carried out, which displayed one of the possible situations of stable development. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

The article presents the indicators for the quantitative assessment of durability and storability developed in this research and mathematical models for their calculation and use in the assessment of the overall dependability of industrial control systems. The relevance of the research is underpinned by the fact that data in digital form during the digital transformation of the economy and society is becoming a key factor in digital manufacturing in general and when used in industrial control systems in particular. Mathematical models are developed for the following indicators: storage life, probability of storability, mean storage life, and gamma-percentile storage life. The proposed system of indicators is new and was developed on the basis of international standards for dependability assessment, such as GOST 27.102-2021, IEC 60319, ISO 2394, GOST R 54989-2012, and ISO/TR 18492:2005. The advantage of the proposed system of indicators is their simplicity and harmonization with the existing calculations of standardized dependability indicators. In further research, the author plans to improve the presented mathematical models of durability and storability assessment and develop a methodology for their consideration in the overall dependability assessment of industrial control systems. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Optimal Tracking control for Leader-Following Consensus of Nonlinear Multiagent Systems

This article investigates distributed adaptive leader-following consensus tracking optimal control problem for nonlinear multiagent systems (MASs) subject to unknown nonlinearities and uncertain external disturbances. In contrast to traditional centralized control, the primary challenge is that only partial subsystems can access the desired reference trajectory. To address this, positive time-varying smooth function compensating terms are introduced to counteract the effects of uncertain external disturbances and unknown desired trajectories. Then, by fusing consensus errors into the backstepping technique, feedforward controllers are given. On this basis, the controlled nonlinear systems are transformed into an equivalent affine form, and feedback optimal controllers are designed using actor and critic neural networks (NNs) to execute control behavior and evaluate control performance. The whole control laws comprise both feedforward and feedback controllers. The proposed distributed adaptive consensus control protocol can simultaneously achieve desired optimal control performance and minimize the cost function, as demonstrated through theoretical analysis and simulation results. © 2025 IEEE.

Animal experiments should minimize pain and discomfort and maximize animal welfare to satisfy the experimental animal 3R principle. The quality of vital signs monitor results collected from conscious and stress-free rodents is superior, ensuring experimental data’s reliability, accuracy, and scientificity. This work proposes a noncontact video-based vital signs continuous monitoring method for unconstrained conscious rodents. First, rodents are tracked using keypoint detection, and regions of interest (ROI) on the rodents are selected based on signal-to-noise ratio (SNR) distribution of vital signs. Second, corner motion within the ROI region is tracked to synthesize skin pulsations, from which respiratory signals are extracted. Finally, a method is proposed to eliminate the influence of respiratory harmonics, thereby removing respiratory interference and extracting the heart rate (HR). Four rats and four mice were used to measure the performance of the proposed method. This work is the first to use a camera to continuously monitor the HR of unrestrained and conscious rodents. Compared with the ground truth [semi-implantable electrocardiogram (ECG)], the relative HR error was 1.86% \pm ~0.82 % and 1.20% \pm ~0.33 % for rats and mice, respectively. This method is used for unconstrained conscious rodents and has high applicability, allowing it to be used in various experimental environments and conditions. At the same time, this work contributes to the development of new methods for continuously and objectively evaluating animal welfare, thereby promoting the development of modern biomedical and ethical research. © 2001-2012 IEEE.
