Exploring Plausible Preference of Body-Centric Locomotion with Reinforcement Learning in Virtual Reality

Zijun Mai, BoYu Gao, Huawei Tu, Haojun Zheng et autres

Investigating users' plausible preferences for body-centric locomotion can help researchers better understand the impact of different factors on this locomotion method and optimize the locomotion configuration for providing a plausible locomotion experience. In this paper, we propose to evaluate users' plausible preferences …

Recognition of feeding sounds of large-mouth black bass based on low-dimensional acoustic features

Shijing Liu, Renyu Qi, Haojun Zheng, Jiapeng Zhang et autres

Introduction The eating sounds of largemouth black bass (Micropterus salmoides) are primarily categorized into swallowing and chewing sounds, both intensities of which are closely correlated with fish density and feeding desire. Therefore, accurate recognition of these two sounds is of significant importance …

Evaluating Plausible Preference of Body-Centric Locomotion using Subjective Matching in Virtual Reality

BoYu Gao, Haojun Zheng, Jingbo Zhao, Huawei Tu et autres

Body-centric locomotion in Virtual Reality (VR) involves multiple factors, including the point of view, avatar representations, tracked body parts for locomotion control and transfer functions that map body movement to the displacement of the virtual viewpoint. Understanding the role of these factors …

Effects of Aspect Ratio on Vortex Dynamics in Starting Rectangular Jets

Haojun Zheng, Lei Gao, S. C. M. Yu

The vortex dynamics of starting rectangular jets with aspect ratios of 1, 4, 8, and 10 is investigated numerically at Reynolds number of 1000. The 45°-axis-switching for the square vortex ring and 90°-axis-switching for the rectangular vortex ring are found to be …

Identification of Large Yellow Croaker under Variable Conditions Based on the Cycle Generative Adversarial Network and Transfer Learning

Shijing Liu, Cheng Qian, Xueying Tu, Haojun Zheng et autres

Variable-condition fish recognition is a type of cross-scene and cross-camera fish re-identification (re-ID) technology. Due to the difference in the domain distribution of fish images collected under different culture conditions, the available training data cannot be effectively used for the new identification …

α-Viniferin-Induced Apoptosis through Downregulation of SIRT1 in Non-Small Cell Lung Cancer Cells

Cheng Huang, Zijun Lin, Jui‐Chieh Chen, Haojun Zheng et autres

α-Viniferin, a natural stilbene compound found in plants and a polymer of resveratrol, had demonstrated potential anti-cancer and anti-inflammatory effects. However, the specific mechanisms underlying its anti-cancer activity were not yet fully understood and required further investigation. This study evaluated the effectiveness …

Secure Authentication with 3D Manipulation in Dynamic Layout for Virtual Reality

Zongyong Bu, Haojun Zheng, Weiqiang Xin, Yi Zhang et autres

Since Virtual Reality (VR) applications are applied with many traditional fields (e.g., education, game, shopping), the user authentication is necessary to protect privacy and security (e.g., Shoulder Surfing attacks). In this work, we design and implement an interactive sphere-like input layout for …

Novel Instant Vacuum Biopsy Needle System

Andrew Barnett, Patrick W. McLaughlin, Haojun Zheng, Jason Z. Moore

This paper explores the benefits of vacuum assistance to 18 gauge needle biopsy. Current biopsy methods are inefficient or have a high rate of failure, causing the need for further painful insertions. A novel needle insertion device was developed to create the …
