Background & Aims: In this study with the aim of benefiting from non-laser sources in photodynamic therapy, photo and radio sensitivity of indocyanine green as a sensitizer in photodynamic and radiation therapies were investigated. Methods: Based on the broad absorption peak of indocyanine green and using non-coherent light, the experiments were performed on human cells derived from breast canc...

We propose a coherent optical and radio seamless network concept that allows broadband access without deployment of additional optical fibers within an optical fiber dead zone while enhancing network resilience to disasters. Recently developed radio-over-fiber (RoF) and digital coherent detection technologies can seamlessly convert between optical and radio signals. A millimeter-wave radio with...

Interactions of ultrahigh energy neutrinos of cosmological origin in large volumes of dense, radio-transparent media can be detected via coherent Cherenkov emission from accompanying electromagnetic showers. Antarctic ice meets the requirements for an e cient detection medium for a radio frequency neutrino telescope. We carefully estimate the sensitivity of realistic antennas embedded deep in t...

in this paper, lagrangian and equations describing one-dimensional anisotropic non-heisenberg model are studied. in this study we used the generalized coherent states in real parametrizations and the feynman path integral for these states in su(3) group. these equations describe nonlinear dynamics of non-heisenberg ferromagnetic chain completely. solutions of these equations are magnetic solito...

background: about 83% of patients with breast cancer (bc) undergo radiation therapy. these patients show various degrees of mild to acute reactions during and after the completion of treatment.the aim of this study was to compare inherent radiosensitivity of gamma-irradiated g0-lymphocytes between bc patients and normal individuals using cytokinesis blocked micronucleous assay. methods: three t...

Some 15% of solar flares having a soft X-ray flux above GOES class C5 are reported to lack coherent radio emission in the 100 – 4000 MHz range (type I – V and decimetric emissions). A detailed study of 29 such events reveals that 22 (76%) of them occurred at a radial distance of more than 800′′ from the disk center, indicating that radio waves from the limb may be completely absorbed in some fl...

A conducting reball expanding at relativistic speed into an ambient magnetic eld generates a rapidly changing electric current which emits coherent electromagnetic radiation at radio frequencies. The critical frequency (upper limit of the emission) strongly depends on the Lorentz factor of the expansion. We have searched for simultaneous radio emission in the data of solar radio spectrographs a...

A cognitive radio is a novel approach in wireless communications. As, the radio spectrum for transmission is very limited but the usage of spectrum is increasing day by day. So for Proper utilization of spectrum the new technology is used, which sense the vacant spectrum and used that space by secondary user. For sensing the spectrum the CR network used various detection techniques such as ener...
