A Diffusive Epidemic Model with Criss-Cross Dynamics

Dynamics of a Delayed Epidemic Model with Beddington-DeAngelis ‎Incidence Rate and a Constant Infectious Period

In this paper, an SIR epidemic model with an infectious period and a non-linear Beddington-DeAngelis type incidence rate function is considered. The dynamics of this model depend on the reproduction number R0. Accurately, if R0 < 1, we show the global asymptotic stability of the disease-free equilibrium by analyzing the corresponding characteristic equation and using compa...

The Criss-Cross Heart

During infancy, the patient was diagnosed with a large VSD and underwent PA banding through a left thoracotomy at the age of 5 months. At the time of PA banding for this patient, two-dimensional echocardiography and MRI were not yet available, and the complex anatomy could not be detected as easily as it can be today. When he was 4 years old, he underwent a sternotomy to close the VSD. However,...

Criss-cross heart with d-ventricular loop.

To the Editor: In a recent issue of Circulation, we saw the interesting images concerning magnetic resonance angiography in a patient with criss-cross heart.1 In the description of the case, the authors correctly report the atrial situs (solitus), the position of the ventricle (inverted), and the connection of the great arteries (discordant with L-position of the aorta). This is the most freque...

Dynamics of an eco-epidemic model with stage structure for predator

The predator-prey model with stage structure for predator is generalized in the context of ecoepidemiology, where the prey population is infected by a microparasite and the predator completely avoids consuming the infected prey. The intraspecific competition of infected prey is considered. All the equilibria are characterized and the existence of a Hopf bifurcation at the coexistence equilibriu...
