The advancement of the Industry 5.0 in information technology has led to increased interest in integrating edge-cloud cooperation with Internet of Things (IoT) and cyber-physical system (CPS) designs. This integration effectively reduces service delays and provides real-time analysis feedback to physical spaces, attracting attention from both academia and industry. These advanced technologies enhance production system intelligence, their alignment with circular economy principles for promoting sustainability has been overlooked. To address this gap, this article proposes an intelligent sustainability evaluation strategy driven by edge-cloud cooperation, IoT, and CPS. The proposed approach aims to enhance production sustainability and intelligence through circular economy perspectives. It introduces improved gray relation analysis and deep clustering network techniques to extract meaningful insights from diverse indicators within the evaluation system. By analyzing relationships between different equipment and workshops, it provides an analytical method that enhances production efficiency while reducing energy consumption and resource waste. To further validate the proposed method, an illustrative example using a partner company’s production data demonstrates its accuracy. © 2014 IEEE.

With an increasing demand for wireless communications, it is difficult for traditional communication technologies to achieve high-quality multi-channel wireless transmissions. Complex-amplitude metasurfaces provide an effective method to deal with this issue by jointly controlling the amplitude and phase of electromagnetic (EM) waves. However, the limitations of single-layer transmission efficiency and amplitude-phase coupling make it challenging to achieve multi-channel high-quality transmission and system integration. Here, a single-layer complex-amplitude metasurface design strategy for multi-channel high-quality transmission is proposed. The amplitude and phase of each transmission channel can be concurrently controlled by adjusting the structural parameters and rotation angles of the resonators. The metasurface successfully reconstructs different holograms in five transmission channels. All experimental results align well with the calculated and simulated results, demonstrating an innovative solution for multi-channel high-quality information transmission, with significant potential applications in the fields of wireless communications. © 2025 Optica Publishing Group.

Although the superior mechanical properties and non-flammability of solid electrolytes substantially improve the safety of Li-ion batteries, these merits are mostly nullified by lower Li ionic conductivity than the organic counterpart. However, the discovery of lithium superionic conductors, such as Li10GeP2S12 (LGPS) with its ionic conductivity comparable to that of the liquid electrolytes used in current Li-ion batteries, marks a turning point as it opens the potential for fast-charging solid-state batteries. In this study, we explore the LGPS-based solid electrolytes with even higher ionic conductivity by adding cation dopants. Using density functional theory (DFT) calculations and machine-learning-based molecular dynamics (ML-based MD) simulations, we demonstrate the crystal structures of LGPS after doping eight different cations of C, Co, Pb, Ti, Sb, Nb, Mn, and Bi. The thorough comparative analysis suggests Pb is a promising dopant that can enhance the ionic conductivity up to 43.5 %, with relatively less degree of synthesis difficulty. The intrinsic atomic mechanisms responsible for this enhanced ionic conductivity are further elucidated by analyzing two Li-ion transport mechanisms of paddle-wheel dynamics and cooperative hopping. With a particular focus on the dopant properties on the dynamics of Li-ions and surrounding tetrahedra, we also provide a fundamental guideline for developing solid electrolytes with superior conductivity. © 2025 Elsevier B.V.

High operation temperatures increase the sodium-ion conductivity of solid-state sodium batteries but may cause early short-circuiting due to sodium-ion flux inhomogeneity and rapid sodium dendrite penetration caused by poor contacts between solid electrolytes particles. This study characterizes Sb-doped Na3Zr2Si2PO12 (Na3.1Zr1.9Sb0.1Si2PO12, NZSbSP) as a prospective solid-state electrolyte and determines its compatibility with sodium-metal electrodes by examining the cycling performance of symmetric Na/NZSbSP/Na cells at 60 °C. Compared with Na3Zr2Si2PO12, NZSbSP exhibits a higher sodium-ion conductivity and sodium-ion transference number while featuring a lower electronic conductivity and activation energy for sodium-ion conduction. The Na/NZSbSP/Na symmetric cell sustains 3055 h of cycling at 0.1 mA cm−2, which reflects the superior compatibility of NZSbSP with sodium metal. The instrumental analyses of NZSbSP after high-temperature operation reveal suppressed dendrite formation and the homogeneity of the sodium-ion flux at the NZSbSP–sodium metal interface. A Na0.67Fe0.5Mn0.5O2/NZSbSP/Na coin cell exhibits a discharge capacity retention of 58.84% after 50 cycles as well as a high coulombic efficiency and sodium-ion diffusion coefficient. The oxidation of Sb during cycling is shown to prevent electrolyte degradation during high-temperature operation and stabilize the electrode interface. These results demonstrate the feasibility of using NZSbSP in solid-state sodium batteries operated at high temperatures. © 2025, The Authors. All rights reserved.

Attributed graph clustering, aiming to discover the underlying graph structure and partition the graph nodes into several disjoint categories, is a basic task in graph data analysis. Although recent efforts over graph contrastive clustering have achieved decent performances, most of them get accustomed to construct the positive neighbor set by the generated pseudo clustering information, directly ignoring the ready-made neighbor nodes and the underlying semantics of edges in a graph. How to well deal with the graph neighbor-specific information to facilitate the performance of graph contrastive clustering is still a challenging problem. Therefore, in this work, we propose a novel Homophily Induced Contrastive Attributed Graph Clustering (HomoCAGC) method, where the power of homophily is exploited in facilitating the performance of contrastive attributed graph clustering, while the pseudo homophily in a graph is also explored and distinguished. Especially, the node feature as reliable information guidance is used to compute the underlying feature-oriented pair-wise node similarity, based on which the positive node pairs in contrastive regularizer are adjusted for better node representation characterization. According to the refined node representations, a triplet self-supervised clustering objective is well-designed to ensure the output embedding is cluster-oriented, and suitable for the downstream clustering task. Extensive experiments on seven benchmarks are conducted to demonstrate the effectiveness of HomoCAGC. © 1991-2012 IEEE.

Despite the importance of genetic testing for risk assessment and treatment in breast cancer, the prognostic impact of germline pathogenic variants (PVs), especially in Asian populations, is unclear. We assessed the impact of germline PVs in patients with early-stage breast cancer. This study included 7278 Japanese multihospital registry patients. PVs of ATM, BRCA1, BRCA2, CDH1, CHEK2, NBN, NF1, PALB2, PTEN, STK11, and TP53 were evaluated. PV and non-PV carriers were matched by age, histology, and stage. Associations between PVs and survival were assessed. The primary outcome was invasive disease-free survival (IDFS). Secondary outcomes included relapse-free survival (RFS), overall survival, and breast cancer-specific survival. We identified 320 (4.4%) patients with BRCA1/2 PVs and 79 (1.1%) with PVs other than BRCA1/2 (non-BRCA1/2). A total of 360 patients (BRCA1/2, n = 289;non-BRCA1/2, n = 71) were matched to 720 noncarriers. Patients with BRCA1/2 PVs had significantly shorter 10-year IDFS (adjusted hazard ratio (aHR) = 2.15;95% confidence interval (CI), 1.61–2.86;p < 0.001);and RFS (aHR = 1.74;95% CI, 1.25–2.44;p = 0.001) than noncarriers. Among patients with hormone receptor-positive HER2-negative breast cancer, BRCA1/2 PV carriers exhibited significantly shorter 10-year IDFS than noncarriers, even those with stage I/II disease (total, aHR = 2.23;95% CI, 1.55–3.23;p < 0.001, Stage I/II, aHR = 2.22;95% CI, 1.43–3.44;p < 0.001). There was no significant difference in 10-year IDFS between the non-BRCA1/2 PV carrier and noncarrier groups (aHR = 1.40;95% CI, 0.67–2.93;p = 0.37). Asian patients with breast cancer carrying germline BRCA1/2 PV, even those with a low recurrence risk, have significantly shorter 10-year IDFS than noncarriers. © 2025 The Author(s).

1 IntroductionText categorization methods based on machine learning always encounter the curse of dimensionality. Therefore, it is crucial to perform feature selection to reduce dimensionality of text vectors. Methods based on the difference between document rate of a term in the positive class and that in the negative class have been widely studied in recent years, which is originated from balanced accuracy measures (ACC2) [1].
