Robotic ultrasound is an emerging and important technology. This technology can help in performing ultrasound imaging in potentially contagious patients while minimizing risks of infections for sonographers (persons who perform ultrasound). This study assesses whether the robotic ultrasound system can reduce the musculoskeletal injuries sonographers endure. We developed a haptically-enabled robotic ultrasound system, which provides sonographers with a sense of touch throughout the scan. The system has haptic capabilities in which the sonographer can feel the contact force remotely and would be able to apply pressure appropriately to safeguard the patient. The system is equipped with various force thresholds. The sonographer can view the patient as well as the transducer’s position and orientation. More than 500 robotic images were captured, and a supplementary evaluation by expert radiologists was conducted to provide initial insights into image quality. In total, 56 subjects, 31 female and 25 male, aged from 21 to 55 years, participated in the clinical trials. An assessment is also carried out on the stimulation of the sonographer’s muscles during conventional vs. robotic scanning. As a result, the sonographer experienced substantial relief in back and neck muscles, right abductor pollicis brevis and right C4 paraspinal, by 88.12%, 89.19%, 93.57%, 82.0%, 72.83%, and 75.1% reduction from manual to teleoperated scenario, respectively. Subjects also reported a much more comfortable experience during robotic ultrasound scans.","PeriodicalId":13079,"journal":{"name":"IEEE Access","volume":"13 ","pages":"75585-75598"},"PeriodicalIF":3.4,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10979984","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although most of the recently proposed methods demonstrate remarkable performance on high-quality datasets, such as LFW, their effectiveness is limited when assessed on low-resolution images. To address this challenge, knowledge distillation and super-resolution techniques have been applied, primarily using the ResNet architecture. However, the performance of deep learning approaches depends in part on the architecture used. In this study, we use neuroevolution with a genetic algorithm (GA) to design Convolutional Neural Networks (CNNs) automatically for low-resolution (LR) FR. To reduce the search time, a binary classifier is used to identify which generated architectures should be trained and which should not. The selected architectures are then trained and evaluated using QUMUL-TinyFace (training partition), a native LR dataset, to obtain their fitness, while the remaining architectures are assessed using a performance predictor model to estimate their fitness, bypassing the training stage. The classifier and performance predictor are trained using the CNN architectures evaluated from previous generations, with the architecture encoding used as a feature vector. The proposed method was assessed on both the QMUL-TinyFace (for face identification) and QMUL-SurvFace (for face verification) datasets, achieving a rank-1 recognition rate of 74.7% and a mean verification accuracy rate of 85.1%, respectively, outperforming results from previously published methods.","PeriodicalId":13079,"journal":{"name":"IEEE Access","volume":"13 ","pages":"75911-75923"},"PeriodicalIF":3.4,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10979850","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It maintains multiple levels of lists, which makes it efficient in traversing sorted data. In addition, it is flexible in inserting and deleting data, while avoiding the restructuring overhead of tree-based structures. However, there are considerable challenges in the conventional skip list design. First, the linked list structure has a drawback in utilizing microarchitecture features such as cache, pipeline, and SIMD (Single Instruction Multiple Data) capability. Second, the skip list randomly selects the level of a new node. That is, the skip list runs based on probability rather than data distribution, which can lead to suboptimal lookup performance. Unlike balanced tree structures, the worst-case lookup performance of a skip list remains O(n). This paper proposes a new data structure called DASL (Deterministic Arrayed Skip List). It follows the algorithm of the skip list, but seamlessly integrates the array and devises a new deterministic raise operation in order to obtain flexibility, microarchitecture-friendliness, and reduced tail latency. In specific, a node in DASL consists of an array structure with multiple elements instead of a single element, taking advantage of the array within a list structure. Additionally, the raise operation is conducted deterministically instead of probabilistically, allowing data to be more balanced in multiple lists. Furthermore, we devise two optimization techniques, utilization-based adaptive intra-node search and uneven split operation. Experimental results with various synthetic and real-world workloads demonstrate that DASL outperforms other state-of-the-art in-memory indexes, including skip list, B+tree, and ART.","PeriodicalId":13079,"journal":{"name":"IEEE Access","volume":"13 ","pages":"78303-78319"},"PeriodicalIF":3.4,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10979934","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Optical Communication, the data can be communicated from source to destination through the established lightpaths. However, as the signal traverses the optical links and devices, its QoT may deteriorate due to various impairments. The QoT is an essential component that determines the connectivity of an optical network. Therefore, ensuring a QoT guarantee is necessary to establish a successful lightpath. Predicting the QoT before establishing lightpaths can guide the routing and allocation of resources required for the lightpaths. In this research, using ML models an appropriate QoT analytical prediction model is developed computationally. Simulations were conducted at a 10 Gbps data rate per channel for 64-channel DWDM systems. The proposed model significantly improves in detecting fiber nonlinearity, and performance was studied using Q-factor, BER, and noise power. The results indicate that the SVM-based classifier with regression learning performs better than any other classifiers discussed in this research. This study assesses the efficiency of the proposed ML models in predicting the QoT for established lightpaths. Results indicate that all the ML classifiers with Regression models can accurately predict the transmission quality for over 90% of lightpaths. However, the proposed SVM-based classifier with a regression model demonstrates superior generalization, with a nearly perfect QoT prediction rate of around 99% for the established lightpaths.

To achieve more natural communication, nonverbal cues—especially those tied to emotional states—are critical and have been studied via deep learning. However, three key challenges persist in existing emotion recognition datasets: 1) most assume human-to-human interaction, neglecting shifts in speech patterns when users address a machine, 2) many include acted emotional expressions that differ from genuine internal states, and 3) even non-acted datasets often rely on third-party labels, creating potential mismatches with speakers’ actual emotions. Prior studies report that agreement between external labels and speakers’ internal states can be as low as 60–70%. To address these gaps, we present the VR-Self-Annotation Emotion Dataset (VSAED), consisting of 1,352 naturally induced and non-acted Japanese utterances (1.5 hours). Each utterance is labeled with self-reported internal emotional states spanning six categories. We investigated: 1) how effectively non-acted, machine-oriented speech conveys internal emotions, 2) whether speakers alter expressions when aware of an emotion recognition system, and 3) whether specific conditions yield notably high accuracy. In experiments using a HuBERT-based classifier, we achieve around 40% recognition accuracy, underscoring the complexity of capturing subtle internal emotions.
