When patients with limb deformities wear a 6-DOF external fixator after surgery, it is impossible to accurately analyze the muscle strength of the relevant muscles to guide patients to carry out rehabilitation training. In view of the above problems,the 3D motion capture system and force measurement platform were used to collect the marker point data set and ground reaction force data of the experimental object wearing the Taylor frame, and the biomechanical simulation software Opensim was used to establish the coupling model of the human lower limb femur with the 6-DOF external fixation support, and the muscle force of the human lower limb femur with and without the 6-DOF external fixation support was analyzed and compared through Opensim. The simulation results show that: compared with the patients without the 6-DOF external fixator, wearing the 6-DOF external fixator will increase the muscle strength of the lower limb related muscles when the patients walk after surgery, and the increase is within the patient's tolerance.

Design of Experient is an integral part of uncertainty quantification. Latin hypercube designs, including methods such as maximizing distance LHDs and maximizing projection LHDs, are widely used for quantifying and computing engineering uncertainties. In particular, it is challenging to construct efficient designs for large designs with high parameter dimensionality and large data volume. In the current literature, various optimization tools exist to select the optimal LHDs, and each method has its advantages and disadvantages. In this paper, we combine commonly used optimization methods with different space-filling criteria to analyze the effects of parameter dimensionality, data volume, and algorithm hyperparameters for solving the problem of flexibility selection of optimization algorithms. The results of this paper can be used as a guide for the selection of optimization algorithms for experimental design aspects of practical engineering applications.

Given the broad adoption of artificial intelligence, it is essential to provide evidence that AI models are reliable, trustable, and fair. To this end, the emerging field of eXplainable AI develops techniques to probe such requirements, counterbalancing the hype pushing the pervasiveness of this technology. Among the many facets of this issue, this paper focuses on baseline attribution methods, aiming at deriving a feature attribution map at the network input relying on a "neutral" stimulus usually called "baseline". The choice of the baseline is crucial as it determines the explanation of the network behavior. In this framework, this paper has the twofold goal of shedding light on the implications of the choice of the baseline and providing a simple yet effective method for identifying the best baseline for the task. To achieve this, we propose a decision boundary sampling method, since the baseline, by definition, lies on the decision boundary, which naturally becomes the search domain. Experiments are performed on synthetic examples and validated relying on state-of-the-art methods. Despite being limited to the experimental scope, this contribution is relevant as it offers clear guidelines and a simple proxy for baseline selection, reducing ambiguity and enhancing deep models’ reliability and trust. © 2025, CC BY.

The increasing prevalence of new phishing and scamming attack methodologies in Indonesia, orchestrated by threat actors, highlights significant concerns for Android users. The dynamic frequency and sophistication of cyberattacks in Indonesia, particularly through Android Package Kit (APK), presents a challenge for cybersecurity researchers and experts to protect the Indonesian public. This research carefully dissects the patterns and tactics used in these fraudulent attacks, explaining the common traits of malicious APKs and the strategies used by threat actors to exploit vulnerabilities in Android devices. A comprehensive examination of APK phishing incidents reported in Indonesia over the past few years forms the basis of this research, drawing insights from various cybersecurity reports, case studies, and digital forensic analyses. The research studied vulnerabilities inherent to the Android system, including behavioral analysis and security lapses on user devices. In addition, an in-depth review was conducted to assess the efficacy of existing cybersecurity measures and policies in Indonesia, measuring their ability to thwart fraudulent APK attacks. This research underscores the importance of more robust security protocols, better user education, and strict regulatory frameworks to mitigate the risks associated with phishing APK attacks. The findings aim to provide cybersecurity professionals, policymakers, and the general public with a deeper understanding of security awareness of the nature and implications of fraudulent APK attacks in improving digital security in Indonesia.

Coating protection is an economical and effective means to prevent the corrosion of metal materials during service. However, organic coatings exposed to the atmospheric environment will also be subject to aging due to various environmental factors. In this paper, aiming at the problem that the mechanism of polyurethane coating atmospheric aging system is unclear and the aging law is difficult to analyze quantitatively, a framework for mining the influencing law of polyurethane coating atmospheric aging is proposed. Firstly, the Clustering Feature Elimination (CFE) algorithm is proposed to solve the problem that the key environmental factors are difficult to determine due to the complex mechanism of coating atmospheric aging. Secondly, based on Random Forest Regression (RFR), the atmospheric aging data-driven model of Polyurethane coating with key environmental factors as input is constructed. Finally, the influence rules of key environmental factors are mined using the model visualization method. The results show that the key environmental factors screened by the CFE algorithm are more consistent with the general law of coating atmospheric aging. The atmospheric aging model of polyurethane coating based on these key environmental factors has higher prediction accuracy. The coating aging law obtained by four-dimensional visualization can further reveal the mechanism of coating atmospheric aging.

In this study, a new self-healing strategy that can simultaneously recover the corrosion resistance and the adhesion strength of coatings was introduced. The coating was based on a shape memory epoxy resin containing ethylene vinyl acetate(EVA) microspheres loaded with Ce(NO_(3))_(3)inhibitors, and was cured at a relatively high temperature to facilitate the fusion of adjacent microspheres for a strengthened self-healing effect. The electrochemical impedance spectroscopy(EIS) and scanning electrochemical microscopy(SECM) results demonstrated that the shape memory effect of epoxy matrix, the filling of molten EVA microspheres as well as the release of Ce(NO_(3))_(3)inhibitors contributed synergistically to suppress the corrosion reaction at the coating damage. After healing, the low frequency impedance modulus of the coatings containing Ce(NO_(3))_(3)-EVA microspheres was three orders of magnitude higher than that of the blank epoxy coating. The adhesion strength of the coatings containing Ce(NO_(3))_(3)-EVA microspheres on the metal substrate was also largely repaired thanks to the strong bonding effect of the EVA microspheres.

作者： Liu, Yong Gao, Qihang Zhang, Ran Gao, Shuo Huang, Anbiao Wang, Wenshuo Beihang University China The School of Instrumentation and Optoelectronic Engineering Beijing Advanced Innovation Center for Big Data-Based Precision Medicine Interdisciplinary Innovation Institute of Medicine and Engineering Beihang University Beijing100191 China The School of Automation Science and Electrical Engineering Beihang University Beijing China

Human-machine interface based on force touch panel has attract enormous attention, for the merits of high human-machine interaction efficiency. Many studies and researches are devoted to diverse force touch technologies. Broad applications in both actual use and research have been developed, such as 3D Touch and force-based keystroke authentication. The fruitful results are based on the assumption that users’ touch habits remain unchanged along the time, thus a stationary customized force sensing model can be build. However, in long-term use, users’ touch habits changed due to time-drifting and specific-event, causing stationary force sensing model’s performance decreased. To address this issue, a rectified artificial neural network for long-term force sensing in piezoelectric touch panels is presented in this paper. With additional information of touching time and sign of specific-event, the predictions of force level are rectified, achieving an accuracy of 94.79% on long-term data set. The proposed technique enables customized force sensing in long-term use and enhancing human-machine interactive efficiency. © 2023, CC BY.
