LINC01204 Negatively Regulates the Effect of MiR-214 on Lung Cancer Cell Apoptosis, Migration, Invasion and Radio-sensitivity
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...
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...
We discuss the nature of the unidentified EGRET source 3EG J1621+8203. In an effort to identify the gammaray source, we have examined X-ray images of the field from ROSAT PSPC, ROSAT HRI, and ASCA GIS. Of the several faint X-ray point sources in the error circle of 3EG J1621+8203, most are stars or faint radio sources, unlikely to be counterparts to the EGRET source. The most notable object in ...
I summarize recent results from radio observations of high redshift star forming galaxies, discuss radio continuum emission as a measure of star formation rate, and consider future capabilities at cm to IR wavelengths. 1 Radio surveys to μJy sensitivity Source counts based on low frequency surveys of the sky with Jy sensitivity showed a significant departure from a Euclidean, non-evolving sourc...
We have constructed and operated the Survey for Transient Astronomical Radio Emission (STARE) to detect transient astronomical radio emission at 611 MHz originating from the sky over the northeastern United States. The system is sensitive to transient events on timescales of 0.125 s to a few minutes, with a typical zenith flux density detection threshold of approximately 27 kJy. During 18 month...
We investigate the tunneling shot noise limits on the sensitivity of a microme-chanical displacement detector based on a metal junction, radio-frequency single-electron transistor (rf-SET). In contrast with the charge sensitivity of the rf-SET electrometer, the displacement sensitivity improves with increasing gate voltage bias and, with a suitably optimized rf-SET, displacement sensitivities o...
Inhibition of heat shock protein 90 (Hsp90) is an attractive modality for cancer therapy. Recent studies presented that an Hsp90 inhibitor, 17AAG (17-allylamino-17-demethoxygeldanamycin), enhanced tumor radio-sensitivity, while this was not observed in normal cells. One of the studies reported that the effect of this drug was only observed in tumor cells carrying the wild-type p53 gene, thus de...
