Bifurcation Analysis of a Predator-Prey Model with Allee Effect and Cooperative Hunting
Yujie Gao, Ton Viet Ta
We propose a novel predator-prey model that integrate two ecologically significant mechanisms: the Allee effect in the prey population and cooperative hunting behavior among predat…
Modeling Predator-Prey Dynamics with Stochastic Differential Equations: Patterns of Collective Hunting and Nonlinear Predation Effects
Junyi Qi, Ton Viet Ta
We investigate predator-prey school interactions in aquatic environments using a stochastic differential equation (SDE)-based, particle-level model that incorporates attraction, re…
Towards High-Fidelity and Controllable Bioacoustic Generation via Enhanced Diffusion Learning
Tianyu Song, Ton Viet Ta
Generative modeling offers new opportunities for bioacoustics, enabling the synthesis of realistic animal vocalizations that could support biomonitoring efforts and supplement scar…
Deep Learning for Automated Identification of Vietnamese Timber Species: A Tool for Ecological Monitoring and Conservation
Tianyu Song, Van-Doan Duong, Thi-Phuong Le +1
Accurate identification of wood species plays a critical role in ecological monitoring, biodiversity conservation, and sustainable forest management. Traditional classification app…
Mathematical Models for Fish Schooling
Linh Thi Hoai Nguyen, Ton Viet Ta, Atsushi Yagi
This note reviews our mathematical models for fish schooling, considered in free space, and in space with obstacle and food resource. These models are performed by stochastic diffe…
Quantifying Fish School Fragmentation under Predation Using Stochastic Differential Equations
Junyi Qi, Thorkil Casse, Masayoshi Harada +2
This study builds upon our previously proposed stochastic differential equation (SDE)-based model to further investigate fish school fragmentation under predation. Specifically, we…
