Local deformation and stiffness distribution in fly wings

open access: yesBiology Open, 2019
Mechanical properties of insect wings are essential for insect flight aerodynamics. During wing flapping, wings may undergo tremendous deformations, depending on the wings’ spatial stiffness distribution.

Compact almost automorphic solutions for some nonlinear integral equations with time-dependent and state-dependent delay

open access: yesAdvances in Difference Equations, 2017
We study the existence of compact almost automorphic solutions for a class of integral equations with time-dependent and state-dependent delay. An application to a blowflies model and a transmission lines model is carried out to support the theoretical ...

Permanence and Existence of Periodic Solutions for Nicholson’s Blowflies Model with Feedback Control and Delay on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2018
Sufficient conditions are established for the permanence in a delayed Nicholson’s blowflies model with feedback control on time scales. Our investigation confirms that the bounded feedback terms do not have any influence on the permanence of this system.

Diversity of Calliphoridae and Sarcophagidae (Diptera: Oestroidea) in a forested area in the municipality of Macaé, RJ, Brazil

open access: yesEntomoBrasilis
Sarcophagidae and Calliphoridae are families of Diptera that cover, respectively, about 3,100 and 1,000 species described worldwide. The species of these families have medical and veterinary importance, due to their role as vectors of pathogenic agents.

New results on periodic solutions of delayed Nicholson's blowflies models

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper is concerned with a class of Nicholson's blowflies models with a nonlinear density-dependent mortality term. We use coincidence degree theory and give several sufficient conditions which guarantee the existence of positive periodic solutions ...

Positive periodic solutions of delayed Nicholson's blowflies model with a linear harvesting term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper is concerned with a class of Nicholson's blowflies model with a linear harvesting term. By applying the method of coincidence degree, some criteria are established for the existence and uniqueness of positive periodic solutions of the model.

Delay effect in the Nicholson's blowflies model with a nonlinear density-dependent mortality term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
This paper is concerned with a class of non-autonomous delayed Nicholson’s blowflies model with a nonlinear density-dependent mortality term. Under proper conditions, we prove that the positive equilibrium point is a global attractor of the addressed ...
