This study aims to develop a deep-learning system (DLS) for automatic detection of spinal metastasis and feature evaluation using computed tomography and to determine the impact of the DLS on physician performance in the detection and assessment of spinal metastasis. DLS assistance in a multireader, multicase test study results in higher sensitivity and specificity in spinal metastasis detection and feature evaluation (all p < 0.001). Additionally, resident physicians show a more significant improvement in sensitivity and specificity compared with attending or chief physicians in spinal metastasis detection and most feature evaluation (p < 0.01). In a cohort test study, resident oncologists assisted by the DLS achieve significantly higher sensitivity and specificity compared with those without assistance (all p < 0.01), except for the sensitivity of vertebral body collapse evaluation (p > 0.01). DLS assistance may improve physicians’ performance in the detection and evaluation of spinal metastases, particularly that of resident oncologists.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202400956","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medical microrobots could be injected into the bloodstream and magnetically navigated to the clot for administering the drugs directly to the target. The magnetic manipulation that is required to navigate medical microrobots depends on various parameters such as the microrobots size, the blood velocity, and the imposed magnetic field gradients. Numerical simulation was used to study the motion of magnetically controlled microrobots flowing through representative cerebral bifurcations, for predicting the magnetic gradients required to navigate the microrobots from the injection point until the target location. Upon thorough validation of the model against several independent analytical and experimental results, the model was used to generate maps and predictive equations providing quantitative information on the required magnetic gradients, for different scenarios. The developed maps and predictive equations are crucial to inform the design, operation, and optimization of magnetic navigation systems for healthcare applications.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202400993","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent achievements have integrated legged mobility with manipulation capabilities, yet the accuracy of end-effector trajectory tracking remains a challenge, which is crucial for practical applications. This study proposes an innovative approach that integrates coordinated trajectory generation with decoupled tracking control to enhance the accuracy of end-effector trajectory tracking. This approach also expands the end-effector's workspace and improves the smoothness of the robot's movements. The trajectory optimization-based coordinated trajectory generator leverages the active motion of the quadruped's body to produce smooth movements. Meanwhile, the decoupled tracking control models the robotic arm and quadrupedal robot as independent floating-base systems, incorporating interaction forces to enhance the overall system's tracking accuracy. Finally, a series of experiments demonstrate that the proposed method can successfully perform a variety of trajectory-tracking tasks, reducing the root mean squared error by 82.7% compared to independent control in the stance mode, and cutting additional computational overhead by 53.4% compared to the unified control.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202500242","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These accelerators require a large network of synaptic elements with high degree of plasticity, high endurance, large integration density, and ultralow programing energy. Although emerging nonvolatile memories exhibit promising potential as synaptic devices, their widespread application in training accelerators is limited due to their low endurance and immature fabrication technology. In contrast, capacitor-less 1 transistor-dynamic random-access memories (1T-DRAMs) have recently emerged as lucrative alternative to the conventional (1T/1C) DRAMs owing to their high scalability and low footprint. Considering the high endurance, large integration density, and ultralow write energy of the 1T-DRAMs, in this work, for the first time, their potential is explored as synaptic elements for online learning. The proposed 1T-DRAM-based synaptic element exhibits multi-level capability (up to 6 bits), a large dynamic range (3.91 × 103), an ultralow energy, and an appreciable linearity for potentiation/depression. The 1T-DRAM-based synaptic element also exhibits a paired pulse facilitation with an exponential decay similar to the biological synapses. Furthermore, a multilayer perceptron utilizing the proposed 1T-DRAM synapses achieves an accuracy of 87.10% on MNIST dataset.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202400912","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Augmented reality (AR) technology currently offers a solution to provide intuitive guidance. To enhance the AR user experience, an automated method for calibrating and dynamically registering deformable tissues is proposed. First, an automatic calibration method is proposed to help register the target tissue from the virtual to the real world. The calibration method is based on a 6D pose estimator, which is built on the feature-matching network, SuperGlue and the depth estimation network, Metric3D. Subsequently, a dynamic registration method is proposed to track the deformation of the target tissue in real-time. Moreover, a piece of cloth is utilized for four automatic calibration trials, resulting in a mean absolute error (MAE) of calibration accuracy at 3.79 ± 0.64 mm. The dynamic registration accuracy is also assessed by varying the deformation of the target, yielding an MAE of 6.03 ± 0.96 mm. Finally, an ex vivo experiment involving a piece of small intestine is conducted to validate the effectiveness of the proposed system, with an MAE of 3.11 ± 0.56 mm for AR calibration and 3.20 ± 1.96 mm for dynamic registration error.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202400845","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
