We point out the existence of some simple string solitons in AdS 5 × S 5 , which at the same time are spinning in AdS 5 and pulsating in S 5 , or vice-versa. This introduces an additional arbitrary constant into the scaling relations between energy and spin or R-charge. The arbitrary constant is not an angular momentum, but can be related to the amplitude of the pulsation. We discuss the soluti...

The antennal pulsating organ of mosquitoes consists of two vesicles, each sending a blood-vessel to the antenna of its side and each connected to the aorta by a muscle. Contraction of the muscle causes blood to enter the vesicle through a valve and relaxation allows an elastic contraction of the vesicle so that the blood is discharged through the blood-vessel to the antenna. The organ appears t...

We consider a diffusional-thermal model with twostep competitive reactions for premixed combustion wave propagation in one spatial dimension. Numerical investigation of the flame speed of the system for different fuel types shows the existence of regions where two stable travelling combustion wave solutions co-exist solutions pertaining to the fast and slow branches. A hysteresis type phenomena...

In this study, a realistic model for dynamic instability of embedded single-walled nanotubes (SWCNTs) conveying pulsating fluid is presented considering the viscoelastic property of the nanotubes using Kelvin–Voigt model. SWCNTs are placed in longitudinal magnetic fields and modeled by sinusoidal shear deformation beam theory (SSDBT) as well as modified couple stress theory. The effect of slip ...
