Diverging fluctuations in a spatial five-species cyclic dominance game
, 2013 A five-species predator-prey model is studied on a square lattice where each species has two prey and two predators on the analogy to the Rock-Paper-Scissors-Lizard-Spock game.

Structural and Dynamic Stability of Model Predator-Prey Systems [PDF]
, 1976 A modified set of Volterra's differential equations for dynamics of prey and predator populations is analyzed. This modification takes three effects into consideration: (1) Satiation of predator resulting in the inability of either predation rate or ...

Advanced Functional Materials, EarlyView.A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

Hopf Bifurcation Analysis of a Predator-Prey Biological Economic System with Nonselective Harvesting
Discrete Dynamics in Nature and Society, 2015 A modified predator-prey biological economic system with nonselective harvesting is investigated. An important mathematical feature of the system is that the economic profit on the predator-prey system is investigated from an economic perspective.

Oscillatory behaviour in a lattice prey-predator system
, 1999 Using Monte Carlo simulations we study a lattice model of a prey-predator system. We show that in the three-dimensional model populations of preys and predators exhibit coherent periodic oscillations but such a behaviour is absent in lower-dimensional ...

Advanced Functional Materials, EarlyView.A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Stability and Hopf Bifurcation in a Delayed Predator-Prey System with Herd Behavior
Abstract and Applied Analysis, 2014 A special predator-prey system is investigated in which the prey population exhibits herd behavior in order to provide a self-defense against predators, while the predator is intermediate and its population shows individualistic behavior. Considering the

A modified predator–prey model for the interaction of police and gangs [PDF]
Royal Society Open Science, 2016 A modified predator–prey model with transmissible disease in both the predator and prey species is proposed and analysed, with infected prey being more vulnerable to predation and infected predators hunting at a reduced rate.
