In conventional plasmonic media and metamaterials, such as metallic wire meshes, a longitudinal mode of an electromagnetic wave manifests itself in frequency overlapping transverse modes, which impedes clear observation longitudinal-mode-specific physical effects. Through interlacing two sets ideal band for the is achieved ranging from zero to plasma frequency, where modes are completely forbid...
In vivo environments are highly crowded and inhomogeneous, which may affect reaction processes in cells. In this study we examined the effects of intracellular crowding and an inhomogeneity on the behavior of in vivo reactions by calculating the spectral dimension (d(s)), which can be translated into the reaction rate function. We compared estimates of anomaly parameters obtained from fluoresce...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
در این پژوهش نحوه ساخت نانوکامپوزییت eva/ag و اثر ضد میکروبی آن در درصدهای مختلف نانو ذره نقره مورد بررسی قرار گرفته است.نانوکامپوزیت حاصل از نطر شکل شناختی ، اندازه ذرات، ساختمان شیمیایی ، با استفاده از تستهای sem(scanning electrou microscopy)،tem (transmission electron microscope) ، xrd (x-ray fluorescence spectroscopy) ،ftir (fourier transform infrared spectroscopy) مورد ارزیابی قرار گرفت. د...
Radio frequency wireless technology is surely one of the most used technologies in indoor localization. Indeed, wireless indoor positioning systems can be easily deployed to track the trajectory of an object or a person respect to other moving elements. Within this scenario, different algorithms are implemented to optimize the localization task. Anyway, the majority of the localization algorith...
BACKGROUND Despite consistently meeting international performance targets for tuberculosis case detection and treatment success, areas where tuberculosis is hyperendemic fail to achieve the predicted epidemiological impact. In this article, we explore the anomalous relationship between defined performance targets and actual reduction in tuberculosis transmission. METHODS In areas where tuberc...
