Lithium-plating-type defects in lithium-ion batteries pose severe safety risks due to their potential to trigger thermal runaway. To prevent defective batteries from entering the market, developing in-line detection methods during manufacturing is critical yet challenging. This study introduces a deep learning-based method for detecting lithium-plating-type defects using formation and capacity grading data, enabling accurate identification of defective batteries without additional equipment. First, lithium-plating-type defect batteries with various types and area ratios are fabricated. Formation and capacity grading data from 154 batteries (48 defective, 106 normal) are collected to construct a dataset. Subsequently, a dual-task deep learning model is then developed, where the reconstruction task learns latent representations from the features, while the classification task identifies the defective batteries. Shapley value analysis further quantifies feature importance, revealing that defective batteries exhibit reduced coulombic efficiency (attributed to irreversible lithium loss) and elevated open-circuit voltage/K-values (linked to self-equalization effects). These findings align with the electrochemical mechanisms of lithium plating, enhancing the model's interpretability. Validated on statistically robust samples shows that the framework achieves a recall of 97.14% for defective batteries and an overall accuracy of 97.42%. This deep learning-driven solution provides a scalable and cost-effective quality control strategy for battery manufacturing. © 2025 Science Press

作者： Wang, Yuan Ruhan, R. Jia, Xiaoxi Zhou, Donghua Zhang, Weiwei Gao, Liping Xiao, Kang Dong, Xiaoping Shi, Qi National Key-Laboratory of Intelligent Tracking and Forecasting for Infectious Disease NHC Key Laboratory of Medical Virology and Viral Diseases National Institute for Viral Disease Control and Prevention Chinese Center for Disease Control and Prevention Beijing 102206 China Basic Medical College North China University of Science and Technology Tangshan 063210 China Shanghai Institute of Infectious Disease and Biosafety Shanghai 200433 China

Mounting evidence shows that short-chain fatty acids (SCFAs), derived mainly from intestinal bacteria, play a significant role in maintaining the homeostasis of the immune system and the central nervous system (CNS). SCFAs, directly or indirectly mediated by SCFA receptors and transporters in neuronal cells, participate in the pathophysiological processes of various neurodegenerative diseases, but their roles in prion diseases are rarely addressed. Here, the abnormal changes in SCFA receptors and transporters in a prion-infected cell line and in the brains of several prion-scrapie-infected rodent models were evaluated by various methods. Markedly decreased GPR41 and MCT4 levels were observed in the brains of scrapie-infected rodents at the terminal stage and in the prion-infected cell line, whereas GPR43 and MCT1 levels did not change significantly. Morphological assays identified close colocalization of both GPR41 and MCT4 with NeuN-positive cells, while only a low amount was observed with Iba1-positive and GFAP-positive cells in the brains of prion-infected mice. Reduction of HO-1, an antioxidative agent in Nrf2 signaling, was observed in the brains of both prion-infected rodent models and the prion-infected cell line. Reductions of GPR41 and MCT4 in the prion-infected cell line were reversible after the removal of prion replication and stimulation with SCFA (sodium propionate) or a GPR41 agonist, accompanied by recovering the HO-1 level and improving cell viability. Our data presented here demonstrate a correlation between alterations in GPR41/MCT4 expression and the shifts in cellular composition that accompany prion pathogenesis. Furthermore, we explore the potential association between SCFA signaling and prion neurotoxicity, identifying it as a crucial area for future research endeavors. © 2025 American Chemical Society.

The last decades have seen a burst of experimental platforms reaching the so-called strong-coupling regime, where quantum coherent effects dominate over incoherent processes such as dissipation and thermalization. This has allowed us to create highly nontrivial quantum states and put counterintuitive quantum-mechanical effects to test well beyond what the founding fathers of quantum mechanics ever thought possible. The strong-coupling regime comes with certain challenges though: The need for a large isolation makes it difficult to access the system for control or monitoring purposes. In this Letter we propose a way to access such systems through an engineered environment that does not compromise their strong-coupling effects. As a proof of principle, we apply the approach to the photon-blockade effect present in nonlinear resonators or Kerr cavities, optomechanical systems, and the open Jaynes-Cummings model, but argue that the mechanism is quite universal. We also propose an architecture based on superconducting circuits where the required unconventional environment can be implemented, opening the way to the experimental analysis of our ideas.

While the LiFePO4-LiCoxNiyMn1-x-yO2 (LFP-NCM) hybrid battery pack has the potential to leverage the unique advantages of both types of batteries, current life cycle assessments fail to resolve the multi-dimensional trade-offs between carbon reduction, resource security, and spatiotemporal heterogeneity in hybrid battery pack production. In this study, the carbon footprint and other environmental impacts during the production of NCM, LFP, and LFP-NCM battery packs are evaluated using life cycle assessment. Meanwhile, the resource supply risks are compared and sensitivity analysis of the carbon footprint is conducted from spatiotemporal perspective. Results show that the carbon footprint of the LFP-NCM configuration is reduced while the peak environmental impacts during production are mitigated compared to single battery pack. Resource supply risks follow the hierarchy NCM > LFP-NCM > LFP, with LFP primarily contributed by lithium and graphite, while NCM and LFP-NCM mainly influenced by cobalt. Spatiotemporal analysis indicates that the carbon footprint is significantly reduced by optimizing energy structures and locating production in renewable-rich regions, and the reduction in LFP-NCM is greater than that in LFP. The LFP-NCM hybrid configuration demonstrates potential for decarbonization and resource sustainability, advancing battery lifecycle environmental performance. © 2025 The Institution of Chemical Engineers

This paper examines the problem of optimal deception attacks against state estimation with partially secured measurements, where smart sensors transmit innovation sequences to the remote end for information fusion. Due to resource limitations or defensive countermeasures, the adversary can only modify data packets transmitted through unreliable channels. Meanwhile, the attack should be synthesized with sophistication to deceive an anomaly detector. To investigate the vulnerabilities of such estimation systems without feedback links and enhance security performance, the optimal attack policy is derived by formulating and explicitly solving a convex optimization problem, with the goal of maximizing the sum of estimation errors. Subsequently, a novel attack detection and resilient state estimation algorithm is proposed to ensure an acceptable level of estimation accuracy. The theoretical performance metrics, including false alarm rates for the proposed detector, are provided. Finally, the effectiveness of the results is confirmed through numerical examples. © 2014 IEEE.

This paper investigates stealthy attacks on sampled-data control systems, where a continuous process is sampled periodically, and the resultant discrete output and control signals are transmitted through dual channels in wireless communication networks. Acknowledging the vulnerability of these transmitted data to cyber threats, we analyze two types of stealthy attacks that compromise either one or both channels. We explicitly present the necessary and sufficient conditions for the existence of stealthy single-channel attacks. To mitigate these security risks, we implement encryption-based countermeasures, including linear time-invariant and periodic encryption methods. We detail sufficient conditions under which these encryption strategies effectively thwart single- and dual-channel stealthy attacks. The effectiveness of these approaches and the theoretical findings are demonstrated through numerical simulations. © 1963-2012 IEEE.

Data-Driven Digital Adaptive Timing Mismatch Calibration for Sub-Nyquist Wideband Sampling

The employment of sub-Nyquist sampling enables the adaptation to the ever-increasing bandwidth demands of wireless communication systems. Multicoset sampling is a nonuniform sub-Nyquist sampling technique that can be realized by using a multi-channel architecture. Nevertheless, the performance of multicoset sampling is significantly affected by timing mismatches among sub-ADCs. Traditional analog calibration scheme mitigates timing mismatch errors by adjusting the sampling clock in the front-end, but its performance is suboptimal due to the difficulty in selecting an appropriate initial step size and the sequential calibration process. In this paper, a data-driven digital adaptive timing mismatch calibration approach is proposed that uses real-time measurement data only to calculate calibration parameters without changing hardware circuits, making it effective for tracking variations in mismatches among multiple channels. Based on the nonlinear relationship between the timing mismatches and the normalized mean squared error of the output spectrum, the proposed data-driven calibration scheme jointly computes calibration parameters among multiple channels in parallel through a series of dynamic linearization data models with a time-varying pseudo-partial derivative parameter estimation procedure, and then adaptively adjusts the sampling matrix in the reconstruction to correct unwanted distortions in the output spectrum. To further improve the calibration performance, particle swarm optimization algorithm is exploited to generate parameter vectors used in the proposed data-driven calibration scheme. Numerical analyses indicate that the proposed data-driven digital calibration scheme can eliminate timing mismatches with fewer calibration iterations and enhanced accuracy. © 2015 IEEE.

Rate Bumpless Switching control for Turbofan control Systems With Actuator Fault Based on Switched Models

IEEE Transactions on aerospace and Electronic Systems 2025年

This article proposes a rate bumpless switching control approach for the turbofan control systems with actuator faults based on switched models. A characterization of the rate bump restraint is introduced, quantifying the rate bump restraint level based on the state magnitude at the switching points. Unlike the existing description of the rate bumpless switching performance, this description more accurately captures the original intent of bumpless switching. By jointly designing the rate bumpless restriction-dependent switching command and dynamic output feedback control law, a robust stability condition is formulated with the actuator fault addressed. The established rate bumpless switching control method is effectively validated through simulation experiments on the hardware-in-the-loop platform and semiphysical experimental testbed. © 1965-2011 IEEE.

The metabolic activity of pathogens poses a substantial risk across diverse domains, including food safety, vaccine development, clinical treatment, and national biosecurity. Conventional subculturing methods typically require several days and fail to detect metabolic activity promptly, limiting their application in many areas. Consequently, there is an urgent need for a method capable of rapidly and accurately detecting this activity. This study builds upon an investigation of the effects of D2O onStaphylococcus aureus (S. aureus), utilizing D2O-probed single-cell Raman spectroscopy to detect the metabolic activity ofS. aureus by the Carbon-Deuterium ratio (C-Dratio). Then, it evaluates the performance of various machine learning models in classifying the metabolic states of the pathogen. Medium D2O concentration below 50 % has no significant impact on the growth and reproduction ofS. aureus or on the classification of metabolic states ofS. aureus based on the fingerprint region by machine learning models. Additionally, as the metabolic activity ofS. aureus decreases, both the C-Dratio and the rate of viable cells also gradually decrease. The support vector machine model demonstrated an accuracy of 99.82 % in classifying viable and deadS. aureus, while the linear discriminant analysis model demonstrated an accuracy of 99.92 % in classifyingS. aureus exhibiting distinct metabolic activities. Therefore, D2O-probed single-cell Raman spectroscopy, combined with high-throughput technology, can rapidly, non-destructively, and accurately detect pathogen metabolic activity, offering valuable applications across multiple fields.

A Generalized Non-local Quasicontinuum Approach for Efficient Modeling of Architected Truss-based Lattice Structures

To mitigate the substantial computational costs associated with modeling the mechanical behavior of large-scale architected lattice structures, this work introduces a concurrent multiscale approach: the Generalized Non-local Quasicontinuum (GNQC) method. GNQC generalizes the classical nonlocal Quasicontinuum framework by eliminating the assumption of affine or high-order deformation patterns for accurate energy sampling in coarse-grained regions and by ensuring consistency with general finite element shape functions used for coarse-graining. The introduced GNQC method offers three key features: (1) a constitutive-model-consistent framework that employs the same lattice constitutive relationship in both the locally full-resolution region and the coarse-grained domain, similar to existing nonlocal QC approaches;(2) a shape-function consistent energy sampling mechanism that aligns with the interpolation order of the generally employed shape functions, differing significantly from existing Quasicontinuum works and substantially reducing computational costs;and (3) consistent interfacial compatibility, which enables seamless energy and force transfer across interfaces between regions of different resolutions without cumbersome interfacial treatments. The performance of GNQC is validated through a series of numerical test cases—including tension, clamped bending, three-point bending, and crack propagation problems—that demonstrate good accuracy. Additionally, the error analysis and convergence behavior of GNQC are investigated. Copyright © 2025, The Authors. All rights reserved.
