A TUMOR-IMMUNE MODEL WITH MIXED IMMUNOTHERAPY AND CHEMOTHERAPY: QUALITATIVE ANALYSIS AND OPTIMAL CONTROL

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2022; 30 (2)

We develop a mathematical model of tumor-immune interactions, including six populations (tumor cells, CD8(+)T cells, natural killer (NK) cells, dendri......

DYNAMIC BEHAVIOR OF A STOCHASTIC NON-AUTONOMOUS PREDATOR-PREY MODEL WITH CROWLEY-MARTIN FUNCTIONAL RESPONSE AND IMPULSES

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2022; 30 (1)

A stochastic non-autonomous one-prey two-predator model with Crowley-Martin functional response and impulses is proposed in this paper. First, by cons......

STOCHASTIC PERIODIC SOLUTION OF A NUTRIENT-PLANKTON MODEL WITH SEASONAL FLUCTUATION

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2022; 30 (4)

In this paper, a stochastic nutrient-plankton model with seasonal fluctuation was developed to investigate how seasonality and environmental noise aff......

STABILITY ANALYSIS AND OPTIMAL CONTROL OF A LYME DISEASE MODEL WITH INSECTICIDES SPRAYING AND VACCINATION

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2022; 30 (3)

This paper studies an SIS-type Lyme transmission model incorporating insecticides spraying and vaccination as interventions. We obtain the positivity ......

DYNAMICS OF AN SIRS EPIDEMIC MODEL WITH PERIODIC INFECTION RATE ON A SCALE-FREE NETWORK

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2022; 30 (3)

Influenced by seasonal changes, the infection rate of many infectious diseases fluctuates in cycles. In this paper, we propose and investigate an SIRS......

COMPETITION AND COOPERATION ON PREDATION: BIFURCATION THEORY OF MUTUALISM

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2021; 29 (01)

In this paper, we investigate two predator-prey models which take into consideration hunting cooperation (i.e., mutualism) between two different preda......

NOTE ON THE UNIQUENESS OF AN ENDEMIC EQUILIBRIUM OF AN EPIDEMIC MODEL WITH BOOSTING OF IMMUNITY

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2021; 29 (02)

For some diseases, it is recognized that immunity acquired by natural infection and vaccination subsequently wanes. As such, immunity provides tempora......

DYNAMICAL BEHAVIOR OF STOCHASTIC COMPETITION BETWEEN PLASMID-BEARING AND PLASMID-FREE ORGANISMS IN A CHEMOSTAT MODEL

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2021; 29 (01)

In this paper, a model of stochastic competition between plasmid-bearing and plasmid-free organisms in a chemostat is investigated. First, we show tha......

THE EFFECTS OF INVASIVE EPIBIONTS ON CRAB-MUSSEL COMMUNITIES: A THEORETICAL APPROACH TO UNDERSTAND MUSSEL POPULATION DECLINE

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (1)

Blue mussels (Mytilus edulis) are important keystone species that have been declining in the Gulf of Maine. This could be attributed to a variety of c......

SIGNAL-TO-NOISE RATIO GAIN VIA CORRELATED NOISE IN AN ENSEMBLE OF NOISY NEURONS

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (1)

The collective response of an ensemble of leaky integrate-and-fire neurons induced by local correlated noise is investigated theoretically. Based on t......

A PROGNOSTIC IMMUNOTHERAPY MODEL FOR 4T1 BREAST CANCER WITH COMBINED CYCLOPHOSPHAMIDE AND TLR AGONIST

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (1)

Based on experimental results of a mouse model provided in the literature, we develop a mathematical model by using system biology approach, aiming to......

CROSS-DIFFUSION-DRIVEN PATTERN FORMATION AND SELECTION IN A MODIFIED LESLIE-GOWER PREDATOR-PREY MODEL WITH FEAR EFFECT

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (1)

Spatial patterns through diffusion-driven instability are stationary structures that appear spontaneously upon breaking the symmetry of the spatial do......

ANALYSIS OF AN AGE-STRUCTURED HIV-1 INFECTION MODEL WITH LOGISTIC TARGET CELL GROWTH

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (4)

In this work, we construct an age-structured HIV-1 infection model to investigate the interplay between T cells and viruses. In our model, we assume t......

SPATIOTEMPORAL DYNAMICS OF A DIFFUSIVE LESLIE-TYPE PREDATOR-PREY MODEL WITH BEDDINGTON-DEANGELIS FUNCTIONAL RESPONSE

期刊: JOURNAL OF BIOLOGICAL SYSTEMS, 2020; 28 (3)

In this paper, we study the spatiotemporal dynamics of a diffusive Leslie-type predator-prey system with Beddington-DeAngelis functional response unde......
