We present the light scattering of individual Plasmodium falciparum-parasitized human red blood cells (Pf-RBCs), and demonstrate progressive alterations to the scattering signal arising from the development of malaria-inducing parasites. By selectively imaging the electric fields using quantitative phase microscopy and a Fourier transform light scattering technique, we calculate the light scatt...
We present the light scattering properties of individual human red blood cells (RBCs). We show that both the RBC static and dynamic scattering signals are altered by adenosine 5'-triphosphate (ATP)-driven membrane metabolic remodeling. To measure the light scattering signal from individual RBCs, we use diffraction phase microscopy together with a Fourier transform light scattering technique. RB...
PURPOSE To determine quantitatively dependence on the wavelength and angle, as a function of depth, of light scattering in the human lens. To compare the result for forward directions with psychophysical data. To derive candidate particle distributions that might be responsible for nuclear light scattering as significant in the psychophysical situation. METHODS The amount of light scattered b...
یکی از عواملی که در فرایند تشکیل تصویر سه بعدی در دستگاهای اولتراسوند اختلال ایجاد می کند، نویز لکه ای است. این نویز باعث افت کیفیت بصری تصاویر می شود و تقطیع خودکار حجمهای بدست آمده را دشوار می سازد. تاکنون روشهای متنوعی برای کاهش نویز لکه ای ارایه شده است. برخی از این روشها نیاز به اطلاعات دقیقی از خصوصیات فنی دستگاه تولید کننده تصویر دارند، که این اطلاعات معمولا در دسترس نمی باشد. روشهایی نی...
In this paper, the optical properties of gold nanoparticles investigated. For this purpose the scattering intensity of a laser beam incident on gold nanoparticles has been studied using Mie theory and their respective curves versus different parameters such as scattering angle, wavelength of the laser beam and the size of gold nanoparticles are plotted. Investigating and comparison of the depi...
In recent years, significant progress in the calculation of HLbL contribution to anomalous magnetic moment muon has been achieved both with data-driven methods and lattice QCD. these proceedings I will discuss current developments aimed at controlling scattering level 10%, as required for final precision Fermilab E989 experiment.
