[02668] Assessment of the role of supplementary food on predatory interactions in the context of biological control

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : Biological control is an eco-friendly approach to suppressing pests or weeds by releasing natural enemies into the environment. Many natural enemies display polyphagous behaviour and consume non-prey sources of nutrition. Although using non-prey food sources positively contributes to the success of biological control, complexity arises when pest demonstrates omnivorous behaviour. In this talk, using the dynamical system theory, we analyse resource-prey-predator interaction when prey and predator consume extra food resources. The stability and various bifurcations occurring in the system and system controllability are systematically investigated. The theoretical observations and their validity are demonstrated through numerical simulations.

[00375] Modelling Typhoid Fever Transmission: Optimal control and Cost-Effectiveness Analysis

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Industrial Contributed Talk
  • Abstract : Typhoid fever has been a public health challenge globally, most especially in the developing countries where sanitation and personal hygiene are not taken serious coupled with non-availability of safe-drinking water. In this paper, a deterministic mathematical model of direct and indirect mode of transmission of Typhoid fever dynamics is formulated to investigate the influence of limited clinical efficacy of antibiotics administer to patients suffering from the disease with optimal control and cost-effectiveness analysis. Typhoid fever has been a public health challenge globally, most especially in the developing countries where sanitation and personal hygiene are not taken serious coupled with non-availability of safe-drinking water. In this paper, a deterministic mathematical model of direct and indirect mode of transmission of Typhoid fever dynamics is formulated to investigate the influence of clinical efficacy of antibiotics administer to patients suffering from the disease. The basic reproduction number is analytically computed, and existence and local stability condition of disease-free equilibrium is investigated. Subsequently, the global sensitivity analysis of the model parameters is computed. The optimal control and cost-effectiveness analysis were also computed. Our results suggest that hygiene practice and awareness campaign, and disinfection or sterilization or bacteria decay control is the most cost-effective in eliminating the disease from the population and from preventing the susceptible individuals from contracting the bacteria disease.

[00431] Modeling Impact of Temperature Changes on Onchocerciasis Disease with Control Strategies

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Industrial Contributed Talk
  • Abstract : This study develops temperature autonomous and temperature non-autonomous compartmental models to examine temperature effect on Onchocerciasis transmission dynamics. We conduct analyses including computation of basic reproduction number, existence of equilibrium, stability of equilibrium states and sensitivity to detect crucial parameters of programs targeted to eradicate the disease. We formulate optimal control model to adopt the cost effectiveness and best control options and perform numerical simulations to evaluate the effect of alternative and complementary control strategies.

[00892] Predicting response to pediatric leukemia with flow cytometry data

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : 15% of children with B-cell acute lymphoblastic leukemia fail to achieve response or long-term remission. With new treatments being developed to provide an alternative for this subset of patients, an improved risk classification at diagnosis can help to plan and prepare for this eventuality. Flow cytometry is currently used to characterize the leukemic clone but it has no prognosis value. In this work we use flow cytometry data at diagnosis from 250 pediatric patients from hospitals in Spain to find features associated with response by means of an array of computational methods.

[02082] Circulating renin-angiotensin systems mediated feedback controls over the mean-arterial pressure

  • Session Date & Time : 3C (Aug.23, 13:20-15:00)
  • Type : Contributed Talk
  • Abstract : Recent research has challenged the classic assumption regarding the renin-angiotensin system that it only has negative effects on the cardiovascular system. This study found that the AT2R-mediated feedback mechanism plays a vital role in maintaining normal blood pressure by controlling the activities of AT1R and renin. The study highlights the importance of considering AT2 receptor adaptor protein and direct agonism at AT2R in treating hypertension and other cardiovascular disorders, in addition to blocking AT1R mediation.
