Attitudes and concerns related to privacy are not homogeneous, but instead differ based on the individual and context at hand. Understanding how these attitudes and concerns vary could inform product, service, and policy design. Questionnaires, such as the Privacy Attitudes Questionnaire (PAQ), can be used to evaluate and derive implications from people’s privacy orientations in numerous domains, including healthcare, social media, and e-commerce. Our objective is to refine the PAQ to reflect areas of privacy concern in today’s landscape. The panel will serve as a forum for conversation about areas of privacy concern, guided by our panelists’ expertise and questions about demographic and user considerations for the revised PAQ, a framework-inspired understanding of privacy, and privacy in healthcare. Insights and perspectives arising from the discussion panel will be considered for subsequent revisions of the PAQ. © 2023 Human Factors and Ergonomics Society.

In confluent cell monolayers, patterns of cell forces and motion are systematically altered near topological defects in cell shape. In turn, defects have been proposed to alter cell density, extrusion, and invasion, but it remains unclear how the defects form and how they affect cell forces and motion. Here, we studied +1/2 defects, and, in contrast to prior studies, we observed both tail-to-head and head-to-tail defect motion occurring at the same time in the same cell monolayer. We quantified the cell velocities, the tractions at the cell-substrate interface, and stresses within the cell layer near +1/2 defects. Results revealed that both traction and stress are sources of activity within the epithelial cell monolayer, with their competition defining whether the cells inject or dissipate energy and determining the direction of motion of +1/2 defects. Interestingly, patterns of motion, traction, stress, and energy injection near +1/2 defects existed before defect formation, suggesting that defects form as a result of spatially coordinated patterns in cell forces and motion. These findings reverse the current picture, from one in which defects define the cell forces and motion to one in which coordinated patterns of cell forces and motion cause defects to form and move.

An optimal axial force is critical for achieving favourable weld joints during FSW. This study investigates the effect of various axial forces with increments of 1000 N on the weld quality of aluminium 6082 plates. Two aluminium 6082 T6 plates were joined using the same parameters, except for the downward forging force of 1, 2, and 3 kN. A scanning electron microscope was used to examine the microstructural recrystallization on the welded zone. Tensile and hardness tests were conducted according to E8/E8m-13a and ASTM E384. Tensile tests show that the tensile properties increase significantly from 1 kN to 2 kN and slightly at 3 kN forge force. As the downward forge force increases, the average material hardness increases on a weld zone.

Knowledge discovery in databases (KDD) is concerned with progress in data analysis tools. Data mining is a crucial parts of the KDD process. Data mining is a method for discovering and extracting patterns from huge medical datasets. There are a number of benefits to using the Support Vector Machine (SVM) algorithm in healthcare systems. SVM is a strong and flexible machine learning algorithm that may excel at certain healthcare analytics applications. SVM is preferred in healthcare systems because of their adaptability, ability to manage imbalanced datasets, feature interpretability, handling of high-dimensional data, handling of classification, predictive modeling tasks, handling of non-linear relationships, resistance to overfitting and provision of a distinct margin of separation. It is essential to carefully consider the unique needs and features of the healthcare application when choosing an algorithm. Healthcare systems that use SVM algorithms do so with the intention of capitalizing on SVM's capabilities to tackle domain-specific problems and tasks. In light of this development, the relevant literature on this topic with regard to approach, SVM algorithm, and outcomes are surveyed. The publications evaluated in this study have been categorized according to their relevance to the disciplines, models, tasks, and approaches discussed. Data mining is the practice of sifting through massive amounts of unstructured data for meaningful patterns and insights. Results show 90% accuracy and 98% precision and F measures of the given medical dataset. © 2024 IEEE.

Biohybrid actuators and robots require the integration of biological materials with synthetic materials. Synthetic materials provide structural support and attachment points for biological materials. One technique for fabricating these synthetic support structures is 3D printing. Although some 3D-printable resins have been designed to be biocompatible, the process for assessing biocompatibility is not reported consistently. Furthermore, the ISO 10993-1 standard emphasizes that biocompatibility must be evaluated based on specific use cases. Therefore, for biohybrid actuator applications, two commercial Asiga dental resins, DentaGUIDE and DentaGUM, were printed using a low-cost, LCD resin printer (Phrozen Sonic Mini 8K) and analyzed for their biocompatibility with C2C12, a muscle cell line commonly used in biohybrid actuators. C2C12 cells were cultured in direct contact with resin samples for 72 h, and their viability was examined using ethidium homodimer-1 and calcein acetoxymethyl ester (calcein AM), fluorescent dyes that mark dead and live cells, respectively. The ratio of calcein AM to ethidium homodimer 1 (CalAM:EthD-1) fluorescence was significantly larger for cultures exposed to the autoclaved (4,941±1,122) or ethanol-sterilized (3,783±683) DentaGUIDE samples as compared to the ratio for cultures exposed to polydimethylsiloxane (PDMS) (autoclaved: 1,940±989, ethanol-sterilized: 345±446). The CalAM:EthD-1 ratio measured in cultures exposed to DentaGUM (autoclaved: 43.67±9.38, ethanol-sterilized: 101.7±86.0) was significantly lower than the ratio found for autoclaved PDMS. This analysis suggested that DentaGUIDE has little to no impact on the health of C2C12, but DentaGUM negatively impacted the culture. Therefore, DentaGUIDE could be a suitable rigid material choice for biohybrid actuators. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

We have been developing a standard test method to assess the self-localization function of drones in a non-GPS environment. In this study, we focus on developing an evaluation environment and trajectory. Because it takes time to construct a real evaluation environment, we constructed an evaluation environment using a simulator developed in our previous study and evaluated the factors, such as the drone flight trajectory and the environmental characteristics, which affect the simultaneous localization and mapping (SLAM) methods. In the verification, four SLAM methods, which are open-source methods available in the robot operating system (ROS), were compared. The results obtained from this study showed that small changes in the environment did not significantly affect the performance of the SLAM methods, whereas the flight trajectories had a significant impact on them.

To protect high-speed trains in derailments, reinforced concrete (RC) derailment containment walls are often built beside the track. The resulting problem is that derailed trains hit the surrounding RC derailment containment wall. This paper aims to investigate high-speed train post-derailment impact responses and evaluate the crashworthiness and containment capacity of the RC derailment containment wall. The finite element (FE) models of the eight-vehicle marshalling high-speed train and RC wall were developed and verified against single rail vehicle derailment test, eight-vehicle marshalling train-to-train impact test, and RC structure drop tower tests. FE simulations of the train post-derailment crash on a curve of 400 m radius were performed in LS-DYNA. Results show that the RC wall is capable of protecting high-speed trains from running off the wall in post-derailment collisions up to 150 km/h, while the train may fall off high-speed railway bridges with a derailment velocity beyond 150 km/h. The vehicles of the derailed train successively hit the RC wall due to the multi-vehicle coupling effect of trains. The number of vehicles hitting the wall increases with the increase in derailment velocity. This study provides engineering help for designing RC walls and protecting high-speed train occupants in post-derailment collisions on a curve. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Shield back-face deformation (BFD) is the result of composite ballistic shields deflecting or absorbing a projectile and deforming towards the user. Back-face deformation can result in localised loading to the upper extremity, where the shield is supported. An anthropomorphic test device upper extremity was modified to quantify applied load due to shield BFD. Four vulnerable locations along the upper extremity were investigated - the hand, wrist, forearm, and elbow - for examining differing boundary conditions and their effect on resultant load. Fifteen shots were conducted on composite shields according to Level III ballistic test standards, with an average bullet velocity of 840.7 ± 5.0 m/s. The mean peak back-face velocity of the shield was 208.9 ± 44.6 m/s. Results showed minimal effect of anatomical location, with only the wrist forces exceeding the elbow (p = 0.004), suggesting a more simplified version of testing may be used for future safety tests. The average duration for all impacts was 0.569 ± 0.233 ms, with no significant differences among locations. This is the first step in developing injury criteria for the upper extremity resulting from behind shield blunt trauma and these data will be used for developing injury thresholds in post-mortem human surrogates. © 2022 International Research Council on the Biomechanics of Injury.

One of the critical components of large-scale manufacturing of bioengineered tissues is the sensing of information for quality control and critical feedback of tissue growth. Modern sensors that measure mechanical qualities of tissues, however, are invasive and destructive. The goal of this project is to develop noninvasive methodologies to measure the mechanical properties of tissue engineering products. Our approach is to utilize acoustic waves to induce nanoscale level vibrations in the engineered tissues in which corresponding displacements are measured in full-field with quantitative optical techniques. A digital holographic system images the tissue’s vibration at significant modes and provides the displacement patterns of the tissue. These data are used to train a supervised learning classifier with a goal of using the comparisons between the experimental vibrational modes and the ones obtained by finite element simulation to estimate the physical properties of the tissue. This methodology has the promise of mechanical properties that would allow technicians to noninvasively determine when samples are ready to be packaged, if their growth deviates from expected time frames, or if there are defects in the tissue. It is expected that this approach will streamline several components of the quality control and production process. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
