Here, we perform systematic studies on the elastic properties of the Cu–6wt% Ag alloy wire, which is a promising candidate material for the new-generation pulsed magnets, by employing two independent ultrasonic techniques, i.e., resonant ultrasound spectroscopy(RUS) and ultrasound pulse-echo experiments. Our RUS measurements manifest that the elastic properties of the Cu–6wt% Ag alloy wires can be improved by an electroplastic drawing procedure as compared with the conventional cold drawing. We also take this opportunity to test the availability of our newly-built ultrasound pulse-echo facility at the Wuhan National High Magnetic Field Center(WHMFC, China), and the results suggest that the elastic performance of the electroplastically-drawn Cu–6wt% Ag alloy wire remains excellent without anomalous softening under extreme conditions,e.g., in ultra-high magnetic field up to 50 T and nitrogen or helium cryogenic liquids.展开更多

文摘The escalating complexity of modern malware continues to undermine the effectiveness of traditional signature-based detection techniques,which are often unable to adapt to rapidly evolving attack patterns.To address these challenges,this study proposes X-MalNet,a lightweight Convolutional Neural Network(CNN)framework designed for static malware classification through image-based representations of binary executables.By converting malware binaries into grayscale images,the model extracts distinctive structural and texture-level features that signify malicious intent,thereby eliminating the dependence on manual feature engineering or dynamic behavioral analysis.Built upon a modified AlexNet architecture,X-MalNet employs transfer learning to enhance generalization and reduce computational cost,enabling efficient training and deployment on limited hardware resources.To promote interpretability and transparency,the framework integrates Gradient-weighted Class ActivationMapping(Grad-CAM)and Deep SHapleyAdditive exPlanations(DeepSHAP),offering spatial and pixel-level visualizations that reveal howspecific image regions influence classification outcomes.These explainability components support security analysts in validating the model’s reasoning,strengthening confidence in AI-assisted malware detection.Comprehensive experiments on the Malimg and Malevis benchmark datasets confirm the superior performance of X-MalNet,achieving classification accuracies of 99.15% and 98.72%,respectively.Further robustness evaluations using FastGradient SignMethod(FGSM)and Projected Gradient Descent(PGD)adversarial attacks demonstrate the model’s resilience against perturbed inputs.In conclusion,X-MalNet emerges as a scalable,interpretable,and robust malware detection framework that effectively balances accuracy,efficiency,and explainability.Its lightweight design and adversarial stability position it as a promising solution for real-world cybersecurity deployments,advancing the development of trustworthy,automated,and transparent malware classification systems.

文摘Synaptic pruning is a crucial process in synaptic refinement,eliminating unstable synaptic connections in neural circuits.This process is triggered and regulated primarily by spontaneous neural activity and experience-dependent mechanisms.The pruning process involves multiple molecular signals and a series of regulatory activities governing the“eat me”and“don't eat me”states.Under physiological conditions,the interaction between glial cells and neurons results in the clearance of unnecessary synapses,maintaining normal neural circuit functionality via synaptic pruning.Alterations in genetic and environmental factors can lead to imbalanced synaptic pruning,thus promoting the occurrence and development of autism spectrum disorder,schizophrenia,Alzheimer's disease,and other neurological disorders.In this review,we investigated the molecular mechanisms responsible for synaptic pruning during neural development.We focus on how synaptic pruning can regulate neural circuits and its association with neurological disorders.Furthermore,we discuss the application of emerging optical and imaging technologies to observe synaptic structure and function,as well as their potential for clinical translation.Our aim was to enhance our understanding of synaptic pruning during neural development,including the molecular basis underlying the regulation of synaptic function and the dynamic changes in synaptic density,and to investigate the potential role of these mechanisms in the pathophysiology of neurological diseases,thus providing a theoretical foundation for the treatment of neurological disorders.
