In this paper we report on an investigation of the effects a self-avatar's visual similarity to user's actual appearance, their perceptions avatar in immersive virtual reality (IVR) experience. We conducted user study examine participant's sense body ownership, presence and realism under three levels avatar-owner similarity: (L1) reconstructed from real imagery (L2) cartoon-like created by 3D artist for each participant, where shoes clothing mimic that but using low-fidelity model, (L3) with...
It is unknown whether artificial intelligence-based computer-aided detection (AI-CAD) can enhance the accuracy of chest radiograph (CR) interpretation in real-world clinical practice. We aimed to compare CR assisted by AI-CAD that conventional patients who presented emergency department (ED) with acute respiratory symptoms using a pragmatic randomized controlled trial.
Abstract With the continued technology innovation in object sensing and human motion tracking, traditional two‐dimensional video‐based tele‐conference systems are projected to evolve into three‐dimensional immersive augmented reality (AR) based on which one can communicate with teleported remote other as if present, moving interacting naturally same location. One technical hurdle this vision is need resolve environmental differences resulting avatar anomaly between local sites. This paper...
A new compatibilizer, polythiophene-graft-poly(methyl methacrylate) (PMMA), for poly(styrene-co-acrylonitrile) (SAN)/multiwalled carbon nanotube (MWCNT) composite is synthesized. Fluorescence emission spectra and Raman indicate that the polythiophene part of compatibilizer strongly interacts with surface MWCNT, while differential scanning calorimeter (DSC) thermograms show PMMA graft miscible SAN matrix. The use yields well-dispersed SAN/MWCNT nanocomposites enhanced mechanical properties,...
The ammonium perchlorate composite propellant is a common choice for solid rocket propulsion. externally heated via fires, instance, can cause the energetic substance to ignite, and this may lead thermal runaway event or slow cook-off phenomenon marked by severe explosion. To develop preventive measures reduce possibility of such accidents in propulsion systems, we investigate ignition initiation characteristics ammonium-perchlorate-based propellants andperform decomposition simulation...
With continued technology innovation, the traditional 2D video based tele-conferencing and collaborative systems are evolving into ones that immersive, 3D, more interactive even augmented in real environment. One important quality of a tele-collaboration system is sense co-presence as felt by participating users. Virtual reality implementations media presentation will have different ramification toward effectiveness communication. In this paper, we propose to carry out preliminary study...
Abstract Objective High-quality cardiopulmonary resuscitation is crucial for the survival of patients experiencing cardiac arrest, but effect chest compression release velocity (CCRV) has not been well studied. The aim this study was to evaluate CCRV on cerebral perfusion pressure (CePP) in an experimental porcine arrest. Methods A ventricular fibrillation (VF)-induced model arrest established 16 pigs. subjects were randomized into a high-CCRV (400 mm/sec) group and low-CCRV (300 group. Six...
Delivery of automatic electrical defibrillator (AED) by unmanned aerial vehicle (UAV) was suggested for out-of-hospital cardiac arrest (OHCA). The goal this study is to assess the effect topographic and weather conditions on call AED attach time UAV-AED. We included OHCA patients from 2013 2016 in Seoul, South Korea. developed a UAV-AED flight simulator using information Seoul Euclidean pathway including vertical overcome high-rise structures. used 4 kinds UAV scenarios according or...
Injuries pose a significant global health challenge due to their high incidence and mortality rates. Although injury surveillance is essential for prevention, it resource-intensive. This study aimed develop validate locally deployable large language models (LLMs) extract core injury-related information from Emergency Department (ED) clinical notes.
