As a well-known physical unclonable function that can provide huge number of challenge response pairs (CRP) with a compact design and fully compatibility with current electronic fabrication process, the arbiter PUF (APUF) has attracted great attention. To improve its resilience against modeling attacks, many APUF variants have been proposed so far. Though the modeling resilience of response obfuscated APUF variants such as XOR-APUF and lightweight secure APUF (LSPUF) have been well studied, the challenge obfuscated APUFs (CO-APUFs) such as feed-forward APUF (FF-APUF), and XOR-FF-APUF are less elucidated, especially, with the deep learning (DL) methods. This work systematically evaluates five CO-APUFs including three influential designs of FF-APUF, XOR-FF-APUF, iPUF, one very recently design (dubbed as MnS1,S2,S3-APUF) and our newly optimized design (dubbed as OAX-FF-APUF), in terms of their reliability, uniformity (related to uniqueness), and modeling resilience. Three DL techniques of GRU, TCN and MLP are employed to examine these CO-APUFs' modeling resilience-the first two are newly explored. With computation resource of a common personal computer, we show that all five CO-APUFs with relatively large scale can be successfully modeled-attacking accuracy higher or close to its reliability. The hyper-parameter tuning of DL technique is crucial for implementing efficient attacks. Increasing the scale of the CO-APUF is validated to be able to improve the resilience but should be done with minimizing the reliability degradation. As the powerful capability of DL technique affirmed by us, we recommend the DL, specifically the MLP technique always demonstrating best efficacy, to be always considered for examining the modeling resilience when newly composited APUFs are devised or to a large extent, other strong PUFs are constructed.

Water is called the “source of life”; it is the foundation of our human existence, and it is also an essential resource in the development of the country. Water pollution mainly includes two aspects. The first is that the water quality is polluted to a certain extent. Although our country has successively introduced many policies and measures to improve the water environment and reduce water pollution in recent years, people’s treatment of the water environment and the degree of attention is still not in place. The other is due to the extensive use of various pesticides and chemical fertilizers in the process of land planting and plant planting, resulting in a decrease in the water storage and drainage capacity of the soil. The quality of water resources has a certain degree of influence on the utilization efficiency of water resources. The full use of water resources refers to the use of water resources as raw materials or production costs into the production and operation process. While promoting urban development, the overall coordinated development of cities in adjacent or similar areas, especially cities with similar or the same water area, should be carried out, so that the development of each city and the development of the water area can coexist harmoniously. The theory of green development lies in the water. The definition in the efficient use of resources is to use the smallest possible investment in water resources in exchange for maximum benefits. This article organically combines the allocation of water resources with the protection and pollution control of the ecological and natural environment, so as to study the utilization of water resources in cities, and provide corresponding theoretical support for the improvement of the ecological environment of water resources and the increasing cleanliness.

Quiescent galaxies are predominantly observed in local galaxy clusters. However, the fraction of quiescent galaxies in high-redshift clusters significantly varies among different clusters. In this study, we present the results of an analysis of the star formation properties of z ∼ 0.87 clusters and groups from a cosmological hydrodynamical simulation Horizon Run 5. We investigate the correlation between the quiescent galaxy fraction (QF) of these model clusters/groups and their various internal or external properties. We find that halo mass is one of the most important characteristics as higher-mass clusters and groups have higher QFs. We also find that other properties such as stellar-mass ratio and FoF fraction, measures the proportion of the area around a cluster occupied by dense structures, may mildly affect the QFs of clusters and groups. This may indicate that the evolutionary history as well as the large-scale environment of clusters and groups also play a certain role in determining the star formation status of high-redshift galaxy clusters and groups. © 2024, CC BY-NC-ND.

Methicillin-resistant Staphylococcus aureus (MRSA) is a human and animal-associated opportunistic pathogen. The bioaerosols from livestock units have been identified to spread MRSA from indoor to outdoor ambient environments and represent a significant risk to public health. Different bioaerosol sampling methods (filtration, impingement, impaction, cyclone, condensation, electrostatic precipitation etc.) have been discussed based on their merits. In this report, we conducted a literature survey approach to understand the lineages of MRSA clones in various livestock air via molecular typing classification, as well as the function of bioaerosol transmission which could impose infection risk in other clean settings. Our analysis found that globally the spa types t011, t002, t034, t127, and t899 are widespread genotype lineages in different livestock's farm air. It is noteworthy that the MRSA clones ST398 and ST9 are most commonly found in livestock settings and carry various types of staphylococcal cassette chromosome mec (SCCmec) elements. In addition, the aerosolization process in livestock units helps to increase the load of MRSA colony in ambient air, which could transmit to the downwind direction of the livestock farms. Ultimately, in the molecular classification of prevalent MRSA clones in livestock settings, the air dynamics are essential in assessing the potential risk of bioaerosol transmission towards outdoor ambient environments. A basic hygiene-driven One-Health approach is critical in mitigating the risks associated with MRSA transmission from livestock settings and promoting public health. Furthermore, to avoid outbreaks, continuous surveillance and effective infection control measures are necessary to prevent the spread of MRSA and other antibiotic-resistant bacteria in both animal and human populations. © 2024 elsevier Ltd

Privacy-preserving federated learning with intermediate-level model sharing

expert Systems with Applications 2025年 291卷

Federated learning allows multiple entities to collaboratively train machine learning models without sharing raw data. Despite its promise of enhancing privacy, sensitive information can still leak through shared model parameters. Additionally, communication inefficiencies and model training under heterogeneous data distributions remain major challenges in federated learning. Although hierarchical architectures offer reasonable solutions, achieving all goals simultaneously remains extremely challenging. This study proposes an intermediate-level model-sharing approach within a hierarchical federated learning framework, considering model performance, communication overhead, and privacy requirements holistically. We evaluated our approach with two privacy mechanisms, first with local differential privacy and second with an intermediate-level perturbation mechanism combined with homomorphic encryption. An extensive set of experiments was conducted adopting a three-tier hierarchical architecture using federated datasets derived from three widely recognized datasets. Results revealed that the proposed model-sharing approach enhances the model utility and exhibits acceptable convergence performance. Additionally, our approach yielded high accuracies in the early stages of training, demonstrating its ability to reduce global communication rounds and thereby decrease the communication burden while increasing privacy. Moreover, the intermediate-level perturbation mechanism achieved better model performance compared to the client-side perturbation. Furthermore, we introduced a fair aggregation mechanism integrating sample-based weighting at intermediate servers and accuracy-based weighting at the central server. Although this did not significantly increase accuracy, it offered greater privacy benefits than mechanisms that rely solely on sample-based weighting. This study underscores the effectiveness of our approach in improving model performance while addressing critical chal

作者： Hussain, Bashir Chen, Jung-Sheng Huang, Shih-Wei Tsai, I-Sen Rathod, Jagat Hsu, Bing-Mu Department of Earth and Environmental Sciences National Chung Cheng University Chiayi County Taiwan Department of Biomedical Sciences National Chung Cheng University Chiayi Taiwan Department of Medical Research E-Da Hospital I-Shou University Kaohsiung Taiwan Institute of Environmental Toxin and Emerging Contaminant Cheng Shiu University Kaohsiung Taiwan Center for Environmental Toxin and Emerging Contaminant Research Cheng Shiu University Kaohsiung Taiwan Doctoral Program in Science Technology Environment and Mathematics National Chung Cheng University Chiayi Taiwan -City Gujarat Gandhinagar India

Understanding the structure, dynamics, and functionality of microbial communities is essential for developing sustainable and effective bioremediation strategies, particularly for sites contaminated with mixed chlorinated volatile organic compounds (CVOCs), which can make the biodegradation process more complex and challenging. In this study, 16S rRNA amplicon sequencing revealed a significant change in microbial distribution in response to CVOCs contamination. The loss of sensitive taxa such as Proteobacteria and Acidobacteriota was observed, while CVOCs-resistant taxa such as Campilobacterota were found significantly enriched in contaminated sites. Additionally, varying abundances of crucial enzymes involved in the sequential biodegradation of CVOCs were expressed depending on the contamination level. Association analysis revealed that specific genera such as Sulfurospirillum, Azospira, Trichlorobacter, Acidiphilium, and Magnetospririllum could relatively survive under higher levels of CVOC contamination, whereas pH, ORP and temperature had a negative influence in their abundance and distribution. However, Dechloromonas, Thiobacillus, Pseudarcicella, Hydrogenophaga, and Sulfuritalea showed a negative relationship with CVOC contamination, highlighting their sensitivity towards CVOC contamination. These findings provide valuable insights into the relationship among ecological responses, the groundwater bacterial community, and their functionality in response to mixed CVOC contamination, offering a fundamental basis for developing effective and sustainable bioremediation strategies for CVOC-contaminated groundwater systems. © 2023 elsevier Ltd
