An electromagnetic coil (the first lens) concentrates the electrons into a more powerful beam. Another electromagnetic coil (the second lens) focuses the beam onto a certain part of the specimen. The specimen s
It took a few decades for Edwin Hall's revolutionary discovery to catch on, but now it's used in all kinds of places—even in electromagnetic space rocket engines. It's no exaggeration to say that Hall's groundbreaking work has had quite an effect!
We propose a mechanism to explain the low-frequency QPOs observed in X-ray binary systems and AGNs. To achieve this, we perturbed stable accretion disks ar
Other evidence of the relevance of our experiments to the jet in the Crab nebula is provided by several important dimensionless parameters. Both jets have a Lorentz factor of the order of unity (Γ=1 for the laboratory plasma jet andΓ≈1.09 for the Crab Nebula jet30). Similarity in the M...
DICS beamforming: Power in the individual α-band (IAF ± 2 Hz) was projected into source-space using a DICS beamformer42utilizing all 306 (magnetometer and gradiometer) channels. A common spatial filter was computed from the averaged cross-spectrum in the IAF band across all segments ...
The connectivity can be defined as a feature/facility that allows one to be in contact with the other or with many to share information or data. It can be analog (in old times) or digital, wired or wireless, etc. The speed of sharing data depends upon the type of technology used ...
Answer to: Cones are visual receptors involved in: a) tonotopic vision. b) scotopic vision. c) photopic vision. d) rhodopsin. e) somatotopic...
Since radio waves are part of the electromagnetic spectrum, they travel at the speed of light (300,000 km/second or 186,000 miles/second), so the waves are picked up almost instantaneously by the other handsets. The radio waves are converted back into fluctuating electric currents and the ...
IEEE Spectrum. Sep 22, 2014. Robots don't need complicated vision if they can pick up RFID signals from nearby objects to help them navigate instead. RFID technology thwarts bird's nest counterfeiters by Jennifer Pak. BBC News, May 29, 2012. An unlikely application of RFID tags in ...
‘between domain’ correlations revealed 8 significantly different correlation coefficients (\(p<0.05\)), and even after most conservative Bonferroni correction (corrected critical\(p=0.05/12=0.0042\)), five of these remained significant (for details, see Supplementary Materials TableS2). This is ...
