Left Ventricular False Tendons (LVFTs) are cord-like structures that traverse the cavity of the left ventricle, connecting the left ventricular free wall or papillary muscle and the ventricular septum without attachment to the mitral valve leaflets.They are incidentally found in autopsy heart specimens.False tendons are generally benign anatomic va
Insect immunity is assorted into humoral and cellular immune reactions.Humoral reactions involve the regulated production of anti-microbial peptides, which directly kill microbial invaders at the membrane and intracellular levels.In cellular immune reactions, millions of hemocytes are mobilized to sites of infection and replaced by hematopoiesis St
Spatial and temporal characteristics of a degenerate four-wave converter in a multimode waveguide with resonant nonlinearity in a scheme with counter-pumping waves are analyzed using the time response function and the point spread function.For single-mode pump waves with equal mode numbers, the dependences of the time response width on the waveguid
