Abstract

The perception of physical objects and miniatures enhances the realism and immersion in VR. This work explores the relationship between haptic feedback from real objects and their visual representations in VR. The study examines how users confirm and adjust the sizes of different virtual objects. The results show that as the size of the virtual cubes increases, users are less likely to perceive the size correctly and need more adjustments. This research provides insights into how haptic sensations and visual inputs interact, contributing to the understanding of visual-haptic illusions in VR environments., Comment: 8 pages, 6 figures, VINCI 2024

Abstract

Objective: Despite extensive research on the link between pornography exposure and sexual aggression, inconsistent results have hindered consensus on the association. To help resolve inconsistencies and advance the field of knowledge, the present study conducted a latent profile analysis to identify common patterns of pornography exposure and to examine their associations with sexual aggression and its risk factors. Method: A total of 491 men in the United States completed assessments of six pornography exposure profile indicators (i.e., frequency of pornography exposure, duration of typical pornography exposure, and exposure to pictures, sex films, degrading films, and violent films) and six outcome variables (i.e., sexual aggression, rape myth acceptance, hostile masculinity, casual sex, psychopathy, and emotion regulation difficulties). Results: The analysis identified three profiles: "infrequent pornography viewers" (n = 113), "average pornography viewers" (n = 302), and "violent pornography viewers" (n = 76). Compared to the infrequent pornography viewers and average pornography viewers profiles, the violent pornography viewers profile had significantly higher means for each outcome variable (ps <.05). Significant differences between the infrequent pornography viewers and average pornography viewers profiles were found for casual sex and difficulties engaging in goal-directed behavior (ps <.05), but not the other outcome variables. Conclusions: Findings provided further insight into the association between pornography and sexual aggression in a way that cannot be observed using a variable-centered approach.

Abstract

While participatory design approaches aim to include stakeholders in all design activities, in resource-limited situations, participation is challenging. Participatory designers often make decisions dealing with the tension between the agency of stakeholder participants and the project's viability. In designing health services, care professionals have limited availability, and patients, such as low-income older adults, have limitations such as lack of transportation and lower access to specialized communication technology or broadband. Yet, it is critical to find innovative ways to engage stakeholders in the design process for services and interventions that aim to improve their health and well-being. This article explores new ways to engage stakeholders in the participatory design process in resource-limited projects. We used a case study approach focused on the design experience of a project focused on social isolation and older adults to understand the complexity of real-world participatory design. While there are tradeoffs between project viability and stakeholders' agency, stakeholders' agency is possible in resource-limited projects. However, experts must adjust and balance influence in different activities to achieve meaningful participation of all stakeholders. [ABSTRACT FROM AUTHOR]

35. Infrared and visible image fusion using a feature attention guided perceptual generative adversarial network.

Author

Chen, Yunfan, Zheng, Wenqi, and Shin, Hyunchul

Abstract

In recent years, the performance of infrared and visible image fusion has been dramatically improved by using deep learning techniques. However, the fusion results are still not satisfactory as the fused images frequently suffer from blurred details, unenhanced vital regions, and artifacts. To resolve these problems, we have developed a novel feature attention-guided perceptual generative adversarial network (FAPGAN) for fusing infrared and visible images. In FAPGAN, a feature attention module is proposed to incorporate with the generator aiming to produce a fused image that maintains the detailed information while highlighting the vital regions in the source images. Our feature attention module consists of spatial attention and pixel attention parts. The spatial attention aims to enhance the vital regions while the pixel attention aims to make the network focus on high frequency information to retain the detailed information. Furthermore, we introduce a perceptual loss combined with adversarial loss and content loss to optimize the generator. The perceptual loss is to make the fused image more similar to the source infrared image at the semantic level, which can not only make the fused image maintain the vital target and detailed information from the infrared image, but also remove the halo artifacts by reducing the discrepancy. Experimental results on public datasets demonstrate that our FAPGAN is superior to those of state-of-the-art approaches in both subjective visual effect and objective assessment.

Abstract

Purpose The study investigates the molecular epidemiology of multi-drug resistant (MDR) Bacteroides spp. isolates and the clinical characteristics of the patients. Materials and methods Bacteroides spp. clinical strains were identified through MALDI-TOF MS and VITEK-2 anaerobes and corynebacterium (ANC) cards. A broth microdilution method was employed to detect the antimicrobial sensitivities of Bacteroides spp. isolates. PCR was used to detect the resistance genes, including cfxA, cepA, cfiA, ermF, nim, as well as the upstream insertion sequence (IS) element of the cfiA gene. The effects of broad-spectrum efflux pump inhibitors (EPIs) on the minimal inhibitory concentration (MICs) of cefoxitin, moxifloxacin, and imipenem for MDR Bacteroides spp. were investigated. Results The total resistance rates of 115 Bacteroides spp. isolates to cefoxitin, moxifloxacin, clindamycin, metronidazole, imipenem and meropenem were 4.3%, 16.5%, 80.0%, 5.2%, 13.9% and 13.9%, respectively. The positive rates of carbapenem resistance gene cfiA were 38.9% and 8.6% for B. fragilis and non-B. fragilis isolates, respectively. The isolation rate of MDR isolates reached up to 18.26% (21/115), and the isolation rate among the gastrointestinal cancer patients was significantly higher when compared to the non-gastrointestinal cancer patients (52.38%/26.08%, P = 0.006). Furthermore, MDR isolates were more likely to be isolated from the patients exposed to cephalosporins 3 months before Bacteroides spp. isolation (76.19%/31.52%, P = 0.000). Conclusion The overall resistance rates of Bacteroides spp. isolates against multiple antimicrobials were at a high level, especially for B. fragilis. The CfiA gene carrying rate among B. fragilis isolates was as high as 38.9%, and its mediated carbapenem resistance was the major resistance mechanism for B. fragilis. The findings of this study imply that the real resistance tendency of Bacteroides spp. may be underestimated and need to be given more attention.
