The formation of Intracardiac thrombi is rare in the absence of structural heart disease or atrial fibrillation. We describe a case of spontaneous right atrial thrombus formation that occurred in a patient with a hypercoagulable condition who had been sub optimally anticoagulated.
We consider wave propagation in random cell materials when the wavelength is finite, so that scattering effects must be taken into account. An effective dielectric coefficient is introduced, which in general is a spatially dependent function, yet reduces, under the infinite wavelength assumptions, to the constant effective parameter in the quasistatic… (More)
