Nearly a dozen of Rotating RAdio Transients (RRATs) have been discovered recently. These objects share similar spin parameters with normal radio pulsars but distinguish themselves from normal pulsars by being quiescent most of the time and only becoming radio bright occasionally. We discuss two possible interpretations to the phenomenon. The first model suggests that these objects are pulsars s...

Relativistic plasma masers operating on the anomalous cyclotronCherenkov resonance ω − k‖v‖ + ωB/ γres = 0 and the Cherenkov-drift resonance ω − k‖v‖ − kxud = 0, are capable of explaining the main observational characteristics of pulsar radio emission. Both electromagnetic instabilities are due to the interaction of the fast particles from the primary beam and from the tail of the secondary pai...

We report the discovery of a coherent magnetic spiral structure within the nearby ringed Sab galaxy NGC4736. High sensitivity radio polarimetric data obtained with the VLA at 8.46GHz and 4.86GHz show a distinct ring of total radio emission precisely corresponding to the bright inner pseudoring visible in other wavelengths. However, unlike the total radio emission, the polarized radio emission r...

background: radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (ir). in this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by cho-k1 cells. materials and methods: whole blood and cho-k1 cells were cultured in rpmi-1640 complete medium. cells were separately irradiated with...

We derive the SZ effect arising in radio-galaxy lobes that are filled with high-energy, non-thermal electrons. We provide here quantitative estimates for SZ effect expected from the radio galaxy lobes by normalizing it to the Inverse-Compton light, observed in the X-ray band, as produced by the extrapolation to low energies of the radio emitting electron spectrum in these radio lobes. We comput...

The advance of wireless communications brings in various schemes of wireless digital communication technology. Analog communication and broadcasting services convert into digital services in many countries. The IBOC (InBand On-Channel) system has been developed to work in the same band with the conventional analog radio and broadcasting digital signal simultaneously. HDR (HD-Radio) standard of ...

The purpose of this study was to determine the correlation between over-expression of the neuropilin 1 (NRP1) gene and growth, survival, and radio-sensitivity of non-small cell lung carcinoma (NSCLC) cells. 3-[4,5-dimethylthylthiazol-2-yl]-2,5 diphenyltetrazolium broide (MTT) and colony assays were then performed to determine the effect of NRP1 inhibition on the in vitro growth of NSCLC cells. ...

The development toward programmatic operation and control of 5G networks is a compelling and technically challenging task. A fundamental component is the capability of exposing and controlling the network state across heterogeneous equipment in a unified manner. In this paper, we outline the COHERENT approach to network abstractions enabling unified representation and programming of heterogeneo...
