Scalable Synaptic Transistor Memory from Solution-Processed Carbon Nanotubes for High-Speed Neuromorphic Data Processing.

Neural networks as a core information processing technology in machine learning and artificial intelligence demand substantial computational resources to deal with the extensive multiply-accumulate operations. Neuromorphic computing is an emergent solution to address this problem, allowing the computation performed in memory arrays in parallel with high efficiencies conforming to the neural networks. Here, scalable synaptic transistor memories are developed from solution-sorted carbon nanotubes. The transistors exhibit a large switching ratio of over 105, a significant memory window of ≈12V arising from charge trapping, and low response delays down to tens of nanoseconds. These device characteristics endow highly stabilized reconfigurable conductance states, successful emulation of synaptic functions, and a high data processing speed. Importantly, the devices exhibit uniform characteristic metrics, e.g., with a 1.8% variation in the memory window, suggesting an industrial-scale manufacturing capability of the fabrication. Using the memories, a hardware convolution kernel is designed and parallel image processing is demonstrated at a speed of 1M bit per second per input channel. Given the efficacy of the convolution kernel, a promising prospect of the memories in implementing neuromorphic computing is envisaged. To explore the potential, large-scale convolution kernels are simulated and high-speed video processing is realized for autonomous driving.

LuckyMera: a modular AI framework for building hybrid NetHack agents

In the last few decades we have witnessed a significant development in Artificial Intelligence (AI) thanks to the availability of a variety of testbeds, mostly based on simulated environments and video games. Among those, roguelike games offer a very good trade-off in terms of complexity of the environment and computational costs, which makes them perfectly suited to test AI agents generalization capabilities. In this work, we present LuckyMera, a flexible, modular, extensible and configurable AI framework built around NetHack, a popular terminal-based, single-player roguelike video game. This library is aimed at simplifying and speeding up the development of AI agents capable of successfully playing the game and offering a high-level interface for designing game strategies. LuckyMera comes with a set of off-the-shelf symbolic and neural modules (called "skills"): these modules can be either hard-coded behaviors, or neural Reinforcement Learning approaches, with the possibility of creating compositional hybrid solutions. Additionally, LuckyMera comes with a set of utility features to save its experiences in the form of trajectories for further analysis and to use them as datasets to train neural modules, with a direct interface to the NetHack Learning Environment and MiniHack. Through an empirical evaluation we validate our skills implementation and propose a strong baseline agent that can reach state-of-the-art performances in the complete NetHack game. LuckyMera is open-source and available at https://github.com/Pervasive-AI-Lab/LuckyMera.

The impact of a brief and immersive use-of-force training exercise on citizens’ attitudes toward police

Purpose Citizens’ attitudes toward police (ATP) have declined dramatically in recent years, prompting many agencies to implement police–community relations programs designed to build back the community’s trust. Such programs are often time-intensive, requiring many hours to complete. The current study examined the impact of a brief (approximately 15 minutes) community relations intervention on citizens’ ATP and police use of force (UoF).Design/methodology/approach A sample of 104 citizens completed three UoF training exercises (i.e., the intervention) inside a video simulator at a municipal police department. Immediately before and after the intervention, citizens’ ATP and police UoF were recorded.Findings Despite having relatively favorable impressions of police at baseline, many attitudes grew to be more favorable following the intervention, including perceptions of job difficulty and the belief that police are treated too harshly by the media. While global impressions of the police did not change, citizens came to believe that greater UoF levels were warranted in specific types of encounters, such as when a suspect tries to strike an officer.Originality/value These findings suggest that providing citizens with an opportunity to experience UoF decision-making first-hand can positively impact certain ATP and police work. Law enforcement agencies may find that such brief, immersive interventions are useful tools for improving police–community relations.

360° Video Simulation Scenario for the WHO Global Patient Safety Challenge "Medication Without Harm".

High-quality video productions integrating 360° simulations of real-life nursing scenarios, though still emerging and relatively rare, have shown promise in enriching learning experiences and refining students' competencies, attitudes, and knowledge. To develop a 360° video simulation scenario for teaching medication safety in nursing. The methodological framework comprised 3 key stages: (1) crafting the script; (2) scrutinizing the script's validity through evaluation by expert judges in medication administration; and (3) developing the set, filming scenes, and refining the video using a 360° camera. All evaluated elements garnered substantial concurrence among the expert panel. After script validation, the video script underwent refinement and validation by expert judges. The 360° video was tailored for utilization with virtual reality glasses, rendering it accessible for integration into nursing education curricula. The final version consisted of a continuous scene that ended with a question that prompted the identification of errors.

Infrasecularity in Stardew Valley

ABSTRACT Stardew Valley is a role-playing and farm simulator video game released by sole creator Eric Barone (online alias ConcernedApe) in 2016. This paper aims to apply an infrasecular (della Dora, V. 2018, “Infrasecular Geographies: Making, Unmaking and Remaking Sacred Space.” Progress in Human Geography 42 (1): 44–71) lens to the analysis of sacred spaces in Stardew Valley. Della Dora’s (2018. “Infrasecular Geographies: Making, Unmaking and Remaking Sacred Space.” Progress in Human Geography 42 (1): 44–71) work on infrasecularity stresses the layered nature of sacred spaces. Different belief systems may be present in a single sacred space that interact with each other over time. This paper analyzes some of the game’s spiritual spaces, including magical ritual spaces, as well as spaces dedicated to reverence of in-game deity “Yoba”. This paper’s methods include auto-ethnography and narrative analysis.

Effects of mindfulness-based music listening on conflict control in young adults with insomnia disorder: behavioral and event-related potential evidence.

Insomnia Disorder (ID) has become the second most prevalent mental disorder, with significant negative effects on daytime cognitive functions. Previous studies suggested that mindfulness-based music listening (MBML) can effectively improve conflict control and attentional processing in healthy adults. However, the behavioral and neurophysiological characteristics of MBML in young adults with ID remain unclear. To explore the behavioral and neurophysiological characteristics of MBML in regulating negative emotions among young Chinese adults with ID, 60 young adults with ID were asked to complete an emotion-word Stroop task under three mood states while recording event-related potentials (ERPs). Task and questionnaire results showed that (1) negative emotion induced by the negative simulated video significantly suppressed the attentional processing of emotional faces and words in the conflict control task among young people with ID, (2) MBML reduced cognitive and physical arousal levels, enhanced positive mood, and improved attentional control abilities in young adults with ID. The ERP results showed that a greater N3 effect and the smaller P3 and late positive component (LPC) effects reflected that MBML effectively regulated negative emotions induced by the negative simulated video and attentional processing abilities for conflict control in young adults with ID. Maintaining mindfulness while listening to music may enhance positive emotional experiences and improve cognitive ability, and exhibit larger N3 effects and smaller P3 and LPC effects in the electrophysiology mechanism, with a reduction in the hyperarousal level in young adults with insomnia disorders.

Virtual play and real connections: unpacking the impact of rice farming simulation video games

This study investigates how the rice farming simulation video game Sakuna: Of Rice and Ruin affects interest in real-world agriculture and the inclination to start farming amidst Japan’s declining farming population. We surveyed 428 Japanese residents, including not only game players but also those who watch the game live or are merely aware of its existence. We also interviewed an individual who started rice farming after playing the game. The findings indicate that the game successfully stimulates greater interest in agriculture and somewhat motivates players to consider farming, more than just viewers or those who are aware of it. Moreover, individuals with real-life connections to agriculture, such as farming experience or professional connections, were optimistic about the transition from game to reality. The study suggests that rice farming simulation games can foster expectations of developing an interest in agriculture and potentially embarking on farming careers, demonstrating the game’s significant impact beyond entertainment.

Online Mindfulness-Based Interventions for Healthcare Professionals: A Scoping Review.

Healthcare professionals work in challenging environments with extended working hours and excessive workloads to provide high-quality care. However, they hardly get the time to care for themselves. Online mindfulness-based interventions-which are not restricted by time or location-can be a powerful strategy to help healthcare professionals. This scoping review aims to explore the current evidence about online mindfulness-based interventions for healthcare professionals. A scoping review was conducted. A literature search was conducted to retrieve articles published between October 2016 and March 2023 in seven databases, including backward and forward citation tracking from the included articles. Among 1,278 articles retrieved, 33 met the criteria for review. Two-thirds of the studies utilized commercialized mindfulness programs (n = 22). Duration of the mindfulness interventions varied from 1 week to 4 months, and half of the studies used audio-guided programs. Online mindfulness-based intervention studies were targeted to reduce burnout (n = 26), and the majority reported reduction in burnout (n = 18). Most studies used individual audio-guided programs that warrant the use of diverse delivery methods such as video media, simulation, and virtual reality for interactions in the future. Although the literature has accumulated evidence for commercialized online mindfulness-based interventions, further studies are needed to develop and test tailored interventions for healthcare professionals.

The effects of video-based simulation in Collaborative Learning in a Student-led Global Classroom (CLSGC) program on non-technical skills among undergraduate nursing students in three regions: A mixed-methods study

BackgroundGlobal nursing shortages and increasing cultural diversity in healthcare necessitate the development of culturally sensitive nurses. Intercultural learning and exchange programs have been shown to enhance nursing students' intercultural knowledge, cultural awareness, and sensitivity. However, non-technical skills such as communication, leadership, and teamwork are less emphasized in existing programs, despite their importance in facilitating adaptation to clinical contexts and ensuring patient safety across different ethnic groups. ObjectiveThis study aims to evaluate the effectiveness of a Collaborative Learning in a Student-led Global Classroom (CLSGC) program that employs video-based learning and student-led debriefings to enhance non-technical skills, and to explore the experiences of undergraduate nursing student participants from three different regions. MethodsSeventy-eight nursing students from the Hong Kong Polytechnic University, Malmo University, and La Trobe University participated in the program. The program included three webinars on teamwork, communication skills, and leadership, facilitated through student-led discussions and video simulations. Data were collected using the Team Strategies and Tools to Enhance Performance and Patient Safety Teamwork Attitudes Questionnaire, and qualitative methods including focus groups and reflective journals. A paired t-test and manifest content analysis were used to analyze the quantitative and qualitative data, respectively. ResultsThe quantitative results indicated significant improvements in the students' attitudes towards teamwork, communication, and leadership. The qualitative data shed light on the students' learning experiences, highlighting the value of cultural exchanges in exploring the importance of non-technical skills in practice, and the effectiveness of the program structure. ConclusionsThe CLSGC program effectively improved nursing students' non-technical skills and enriched their clinical practice. Integrating simulation-based learning and student-led debriefing sessions to enhance nursing students' knowledge and attitudes towards teamwork, communication, and leadership is recommended in nursing education. Continuous exposure to simulation should be part of nursing education to reinforce the significance of non-technical skills in practice.

Estimation of Inferior Vena Cava Size from Ultrasound Imaging in X-Plane

Ultrasound (US) scans of the inferior vena cava (IVC) provide useful information on the volume status of a patient. However, their investigation is user-dependent and prone to measurement errors. An important technical problem is the objective difficulty in studying a very compliant blood vessel like IVC, which makes large respirophasic movements and shows a complicated three-dimensional geometry. Using bi-dimensional (2D) B-mode views either in a long or short axis has improved the characterization of IVC dynamics compared to measurements along a single direction (M-mode). However, specific movements of the IVC can also challenge the information provided by these 2D sections. Thus, these two orthogonal views, provided by an US system in the X-plane, are integrated here using an innovative method. It is tested on simulated videos of the IVC by performing complicated movements, which are compensated by the new method, overcoming the biased measurements provided by 2D scans. The method is then applied on example experimental data.

EXPERIENCE MUSEOLOGY AND EPHESUS EXPERIENCE MUSEUM

In the rapidly changing world of the 21st century, museums are not only places where exhibits are stored, but also turn into experience centers that offer more opportunities to their visitors. As a concept created by this transformation, the experience museum offers visitors the opportunity to interact not only by watching the works, but also by experiencing the artifacts and historical processes. In addition, in this process, concepts such as experience museology and immersive reality have emerged with the use of technological tools such as AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality), AI (Artificial intelligence), hologram, simulation and 360-degree video mapping. With the technologies used in the Ephesus Experience Museum, an immersive environment has been created that appeals to the visual or auditory senses of the audience. While visiting the museum in this immersive environment, visitors also experience the historical process by listening to it through audio guides. In this article, by focusing on the museums developed in line with technological possibilities, the Ephesus Experience Museum was visited and examined in the context of experience museology, and the data obtained from the literature review were tried to be analyzed by comparing them with the experience museums in the west. A different exhibition atmosphere has been created with the technological facilities used in the Ephesus Experience Museum. Visitors' experience of the museum has also increased the information opportunities. At the same time, the deficiencies of the Ephesus Experience Museum have been identified. Celsus (Selçuk) Library, one of the important structures of the ancient city of Ephesus, and other historical buildings were not included in the storytelling, and this created a lack of stories. It is thought that this deficiency can be achieved with QR code or augmented reality applications.

Simulated fire video collection for advancing understanding of human behavior in building fires.

The goal of the present research was to develop a video collection of simulated fires to investigate how people perceive growing building fires. In fire safety science, a critical factor to occupant responses to building fires is the pre-movement period, determined by how long it takes an individual to initiate taking protective action with an incipient fire. Key to studying the psychological processes that contribute to the duration of the pre-movement period is presenting human subjects with building fires. One approach used in previous research is to present videos of building fires to individuals via scenarios. The numerical simulations used to model fire dynamics can be used to render videos for these scenarios. However, such simulations have predominantly been used in fire protection engineering to design buildings and are relatively inaccessible to social scientists. The present study documents a collection of videos, based on numerical simulations, which can be used by researchers to study human behavior in fire. These videos display developing fires in different types of rooms, growing at different rates, different smoke thickness, among other characteristics. As part of a validation study, participants were presented with subsets of the video clips and were asked to rate the perceived risk posed by the simulated fire. We observed that ratings varied by the intensity and growth rate of the fires, smoke opacity, type of room, and where the viewpoint was located from the fire. These effects aligned with those observed in previous fire science research, providing evidence that the videos could elicit perceived risk using fire simulations. The present research indicates that future studies can utilize the video library of fire simulations to study human perceptions of developing building fires as situational factors are systematically manipulated.

Gamification Attributes to Enhance Socio-Vocational Readiness Among People with Autism Spectrum Disorder and Intellectual Developmental Disabilities: A Conceptual Paper

People with disabilities, such as autism spectrum disorder (ASD) and intellectual developmental disabilities (IDD) may experience obstacles in social, communication, vocational, and behavioral skills that limit their participation. Video modeling (VM) entails demonstrating desired behaviors through video simulation. Its effectiveness in encouraging adaptive behaviors in work-related social activities has been demonstrated for ASD and IDD. Gamification is the application of game attributes to nongame situations. Within health care, education, and rehabilitation, gamification has included simulations of real-life events to engage clients and improve function. In this conceptual paper, we examined the link between gamification’s intrinsic attributes and the VM paradigm through examples of our evolving VM studies for individuals with ASD and IDD. The discussed interfaces demonstrate gamification attributes that likely contributed to their usability and effectiveness. This conceptual framework illustrated a new perspective concerning the effectiveness of VM paradigms. We encourage clinicians and technology developers to consider the value of incorporating gamification when designing VM interventions to enhance independence in the daily lives of vulnerable populations. Embracing gamified VM can promote engaging interventions, enhancing skill acquisition across diverse populations.

Accurate neuron segmentation method for one-photon calcium imaging videos combining convolutional neural networks and clustering

One-photon fluorescent calcium imaging helps understand brain functions by recording large-scale neural activities in freely moving animals. Automatic, fast, and accurate active neuron segmentation algorithms are essential to extract and interpret information from these videos. One-photon imaging videos’ low resolution, high noise, and high background fluctuation pose significant challenges. Here, we develop a software pipeline to address the challenges of processing one-photon calcium imaging videos. We extend our previous two-photon active neuron segmentation algorithm, Shallow U-Net Neuron Segmentation (SUNS), to better suppress background fluctuations in one-photon videos. We also develop additional neuron extraction (ANE) to locate small or dim neurons missed by SUNS. To train our segmentation method, we create ground truth neurons by developing a manual labeling pipeline assisted with semi-automatic refinement. Our method is more accurate and faster than state-of-the-art techniques when processing simulated videos and multiple experimental datasets acquired over various brain regions with different imaging conditions.

Furthermore, the researchers carried out a teacher and student readability test on the simulation video media. The scores obtained were 91,2% for teachers and 89,2% for students. So that simulation video products able as media supplements in learning.

Development of a virtual reality simulator for training canine endotracheal intubation technique and evaluation of the educational impacts

Virtual reality (VR)-based training has shown some benefits in medical education, supporting skill acquisition, and helping reduce anxiety in real-world settings. However, the use of VR simulators in veterinary education remains limited. This study aimed to introduce a VR simulator to support veterinarian training in canine anaesthesia induction and endotracheal intubation. This study involved a group that learned solely with instructional videos (video group), and one that learned concurrently with the video and VR simulator (VR group). Third- and fourth-year veterinary students were included and underwent a descriptive test on canine endotracheal intubation. Canine endotracheal intubation success rates were compared between the video (n = 364) and VR (n = 60) groups of fifth-year students. A survey on the VR usability was conducted (n=91). The median descriptive test scores improved in the VR (63.3/100) vs the video group (51.5/100). The canine intubation success rates were comparable in the VR and video groups at 84.3 % and 77.4 %, respectively. A total of 90.1 % of the surveyed students rated the ease of use of the simulator highly. Overall, VR simulators were well-received, suggesting benefits in new skill retention. Further studies are required to evaluate the extent of skill improvement through VR-based training, compared to conventional methods, and to assess its impact on student motivation. Evaluating the long-term effects of VR-based training on skill development and retention will also provide a deeper understanding of its educational benefits.

Influence of Simulation and Interactivity on Human Perceptions of a Robot During Navigation Tasks

In Human-Robot Interaction, researchers typically utilize in-person studies to collect subjective perceptions of a robot. In addition, videos of interactions and interactive simulations (where participants control an avatar that interacts with a robot in a virtual world) have been used to quickly collect human feedback at scale. How would human perceptions of robots compare between these methodologies? To investigate this question, we conducted a 2x2 between-subjects study (N=160), which evaluated the effect of the interaction environment (Real vs. Simulated environment) and participants’ interactivity during human-robot encounters (Interactive participation vs. Video observations) on perceptions about a robot (competence, discomfort, social presentation, and social information processing) for the task of navigating in concert with people. We also studied participants’ workload across the experimental conditions. Our results revealed a significant difference in the perceptions of the robot between the real environment and the simulated environment. Furthermore, our results showed differences in human perceptions when people watched a video of an encounter versus taking part in the encounter. Finally, we found that simulated interactions and videos of the simulated encounter resulted in a higher workload than real-world encounters and videos thereof. Our results suggest that findings from video and simulation methodologies may not always translate to real-world human-robot interactions. In order to allow practitioners to leverage learnings from this study and future researchers to expand our knowledge in this area, we provide guidelines for weighing the tradeoffs between different methodologies.
